Abstract
Background The influence of homeostatically regulated physiological processes, including cardiorespiratory fitness (VO2max), on the response to physical stressors such as acclimatisation and marching, remains understudied. We aimed to investigate the effects of summer and winter acclimatisation and marching on cortisol levels and blood lactate, to gain insight into the role of these physiological processes in the stress response. Methods Two groups of young Europeans, classified as poor (PCF; n=9) and good physical condition (GCF; n=21), based on a VO2MAX threshold of 40 mL O2/ kg/min, underwent 2-h March (6-7 km/h) in winter (5˚C) and summer (32˚C). Commercial tests, UniCel DxI Access Cortisol assay and EKF Biosen Clinic/GP assay were used for cortisol and lactate blood measurements (morning samples and those taken immediately after marches), respectively.

Abstract
As part of this study, the mechanisms of the antioxidant activity of previously synthesized coumarin-trihydrobenzohydrazine derivatives were investigated: (E)-2,4-dioxo-3-(1-(2-(2″,3″,4″-trihydroxybenzoyl)hydrazineyl)ethylidene)chroman-7-yl acetate (1) and (E)-2,4-dioxo-3-(1-(2-(3″,4″,5″-trihydroxybenzoyl)hydrazineyl)ethylidene)chroman-7-yl acetate (2). The capacity of the compounds to neutralize HO• was assessed by EPR spectroscopy. The standard mechanisms of antioxidant action, Hydrogen Atom Transfer (HAT), Sequential Proton Loss followed by Electron Transfer (SPLET), Single-Electron Transfer followed by Proton Transfer (SET-PT), and Radical Adduct/Coupling Formation (RAF/RCF) were examined using the QM-ORSA methodology. It was estimated that the newly synthesized compounds, under physiological conditions, exhibited antiradical activity via SPLET and RCF mechanisms. Based on the estimated overall rate constants (koverall), it can be concluded that 2 exhibited a greater antiradical capacity. The obtained values indicated a good correlation with the EPR spectroscopy results. Both compounds exhibit approximately 1.5 times more activity in comparison to the precursor compound used in the synthesis (gallic acid).

Abstract
The aim of this study was to compare knee extensor and flexor strength recovery following anterior cruciate ligament (ACL) reconstruction between bone-patellar tendon-bone (BPTB) and hamstring tendon (HT) grafts in international male soccer players undergoing comparable 6-month rehabilitation programmes. Seventeen players underwent ACL reconstruction with either an autogenous BPTB graft or HT graft. Knee extensor and flexor peak torques were measured at 3 months and 6 months in the injured and contralateral legs following surgery using isokinetic dynamometry. The moderate-large asymmetries in knee extensor peak torque between legs at 3 months across graft types (BPTB: p = 0.002, g = -0.94; HT: p = 0.02, g = -0.55) were reduced to trivial asymmetries at 6 months (BPTB: p = 0.30, g = -0.19; HT: p = 0.40, g = -0.16), with a non-significant difference in limb symmetry index (LSI) between grafts at 6 months (p = 0.62, g = -0.24). Similarly, moderate-large asymmetries in knee flexor peak torque between legs at 3 months across graft types (BPTB: p = 0.13, g = -0.50; HT: p = 0.01, g = -0.97) were reduced to trivial-small asymmetries at 6 months (BPTB: p = 0.25, g = 0.18; HT: p = 0.01, g = -0.47); however, a superior LSI was evident with BPTB compared to HT grafts at 6 months (p = 0.007, g = 1.43, large). Strength and conditioning professionals working with soccer players who are rehabilitating from ACL reconstruction after receiving a HT graft should give adequate attention to delivering suitable hamstring exercises that ensure optimal strength restoration.

Abstract
The objective of this study was to synthesize seven novel thiourea derivatives of naproxen (8-14), examine the anti-inflammatory activity of the newly synthesized compounds, investigate the cytotoxic potential of both sets of synthesized compounds (1-7 and 8-14), and select the most promising anti-inflammatory and antitumor drug candidates. The results of the in vivo anti-inflammatory study clearly showed that compounds 8 and 9 were capable of decreasing paw edema, as evident from a high percentage of inhibition (44.83% and 49.29%, respectively). In addition, the results of in vitro enzyme inhibition assays demonstrated that neither of the newly synthesized compounds reached 50% inhibition of 5-LOX at concentrations lower than 100 µM. In terms of antitumor potential, derivatives 3 and 8 exhibited strong cytotoxic effects on the HeLa cell line, suggesting the involvement of the extrinsic pathway of apoptosis. According to the overall results obtained for both sets of synthesized molecules, derivatives 4 and 8 can be underlined as molecules with the strongest anti-inflammatory activity, while derivatives 3 and 8 are the most promising cytotoxic agents.

Abstract
We describe the preparation, dynamic, assembly characteristics of vase-shaped basket 13- along with its ability to form an inclusion complex with anticancer drug mitoxantrone in abiotic and biotic systems. This novel cavitand has a deep nonpolar pocket consisting of three naphthalimide sides fused to a bicyclic platform at the bottom while carrying polar glycines at the top. The results of 1 H Nuclear Magnetic Resonance (NMR), 1 H NMR Chemical Exchange Saturation Transfer (CEST), Calorimetry, Hybrid Replica Exchange Molecular Dynamics (REMD), and Microcrystal Electron Diffraction (MicroED) measurements are in line with 1 forming dimer [12 ]6- , to be in equilibrium with monomers 1(R) 3- (relaxed) and 1(S) 3- (squeezed). Through simultaneous line-shape analysis of 1 H NMR data, kinetic and thermodynamic parameters characterizing these equilibria were quantified. Basket 1(R) 3- includes anticancer drug mitoxantrone (MTO2+ ) in its pocket to give stable binary complex [MTO⊂1]- (Kd =2.1 μM) that can be precipitated in vitro with UV light or pH as stimuli. Both in vitro and in vivo studies showed that the basket is nontoxic, while at a higher proportion with respect to MTO it reduced its cytotoxicity in vitro. With well-characterized internal dynamics and dimerization, the ability to include mitoxantrone, and biocompatibility, the stage is set to develop sequestering agents from deep-cavity baskets.

Abstract
OBJECTIVE To quantify and compare injury incidence between national-level, adolescent and regional-level, senior, male basketball players competing in Serbia overall and according to injury mechanism (contact, non-contact, or overuse), exposure setting (training or games), and history (new or recurrent). METHODS A total of 218 male basketball players from 19 teams (106 senior and 112 adolescent players) volunteered to participate in the study. Descriptive data regarding game and training injury incidence were gathered across all players and reported per 10,000 athlete-exposures (AE) with 95% confidence intervals. RESULTS Overall, 26 injuries were reported across 52,509 AE. Ankle (n = 10, incidence rate [IR] = 1.90 [0.97, 3.40]) and knee injuries (n = 8, IR = 1.52 [0.71, 2.89]) accounted for 69% of all reported injuries, with only 1-2 injuries documented for other body regions. Ankle injuries were attributed to contact (60%, IR = 1.14 [0.46, 2.38]) or non-contact mechanisms (40%, IR = 0.76 [0.24, 1.84]). Most knee injuries occurred due to overuse (50%, IR = 0.76 [0.24, 1.84]) or non-contact mechanisms (38%, IR = 0.57 [0.15, 1.56]). Comparisons according to exposure setting revealed significantly higher knee (incidence rate ratio [IRR] = 9.95 [1.85, 53.41], p = 0.004) and ankle (IRR = 39.79 [7.94, 384.67], p < 0.001) injuries per 10,000 AE during games compared to training. Recurrent injuries were most prominent in the ankle (30% of all ankle injuries, p = 0.11). Total contact (p = 0.04), non-contact (p = 0.04), and recurrent IR (p = 0.005) were significantly higher in senior than adolescent players. CONCLUSION The players examined were most susceptible to ankle and knee injuries, particularly during games compared to training. Ankle injuries were mostly attributed to player contact, while knee injuries were mostly attributed to overuse and non-contact mechanisms. Senior players were at a greater risk of sustaining contact, non-contact and recurrent injuries than adolescent players.

Abstract
OBJECTIVE To assess the effects of a novel multicomponent neuromuscular warm-up program on lower-extremity injury incidence in basketball players competing at the regional level. METHODS A cluster randomized controlled experimental design was adopted to compare injury incidence between players exposed to the injury prevention warm-up program and those exposed to a typical warm-up program across an entire basketball season. Four teams consisting of 57 players (male: n = 42; female: n = 15) were allocated to the intervention group (age: 21.6 ± 2.5 years; height: 186.2 ± 8.8 cm; body mass: 80.0 ± 10.4 kg) and four teams consisting of 55 players (male: n = 43; female: n = 12) were allocated to the control group (age: 21.6 ± 2.6 years; height: 186.9 ± 9.1 cm; body mass: 81.5 ± 10.9 kg). The novel warm-up combined running exercises with active stretching, plyometrics, balance, strength, and agility drills. Coaching and medical staff provided details on injury incidence each week. Data analyses included the use of poisson regression analyses and the incidence rate ratio (IRR) with 95% confidence intervals (CI). RESULTS The intervention group experienced a significantly lower ankle sprain incidence rate (IRR = 0.26, 95% CI = 0.05, 0.98, p = 0.02) and a tendency toward a lower knee injury incidence rate (IRR = 0.32, 95% CI = 0.03, 1.78, p = 0.07) compared to the control group. Considering only non-contact lower-extremity injuries of any type, the intervention group experienced a significantly lower incidence rate compared to the control group (IRR = 0.26, 95% CI = 0.05, 0.98, p < 0.001). CONCLUSION This multi-team study demonstrated a novel multicomponent warm-up program resulted in less lower-extremity injuries, particularly ankle sprains and knee injuries, compared to a typical warm-up program in regional-level male and female basketball players.

Abstract
The aim of the study was a synthesis and investigation of the dose-dependent anti-inflammatory effect of new thiourea derivatives of naproxen with selected aromatic amines and esters of aromatic amino acids. The results of the in vivo study indicate that derivatives of m-anisidine (4) and N-methyl tryptophan methyl ester (7) showed the most potent anti-inflammatory activity four hours after injection of carrageenan, with the percentage of inhibition of 54.01% and 54.12%, respectively. In vitro assays of COX-2 inhibition demonstrated that none of the tested compounds achieved 50% inhibition at concentrations lower than 100 µM. On the other hand, the aromatic amine derivatives (1-5) accomplished significant inhibition of 5-LOX, and the lowest IC50 value was observed for compound 4 (0.30 μM). High anti-edematous activity of compound 4 in the rat paw edema model, together with potent inhibition of 5-LOX, highlight this compound as a promising anti-inflammatory agent.

Abstract
The aim of this study was to compare QT dispersion (QTd) and echocardiographic parameters in male athletes competing across different sports (long-distance running, volleyball, football, powerlifting, and bodybuilding) and a control population. Significant moderate-strong differences (p < 0.001, [Formula: see text] = 0.52-0.71) were found in corrected QTd, intraventricular septal wall thickness (ISWT), posterior wall thickness (PWT), relative wall thickness (RWT) and LV (left ventricular) index between groups. Corrected QTd, ISWT, PWT, and RWT were significantly (p < 0.001) higher in powerlifters and bodybuilders compared to other athlete groups and controls. While all athlete groups displayed a significantly higher LV index (p < 0.05) compared to controls, corrected QTd was significantly lower (p < 0.001) only in long-distance runners, volleyball athletes, and football athletes compared to controls. Normal or eccentric LV hypertrophy (LVH) was observed in most long-distance runners (58% and 33%), volleyball athletes (50% and 50%), and football athletes (56% and 41%). In contrast, concentric LVH was observed in most powerlifters (58%) and bodybuilders (54%). Advanced LVH, predominantly concentric in nature, appears to be accompanied with increased QTd in powerlifters and bodybuilders. On the other hand, runners, volleyball athletes, and football athletes experienced LVH toward the upper threshold of the normal reference range alongside reduced QTd compared to other groups.

Abstract
ABSTRACT Milutinović, A, Jakovljević, V, Dabović, M, Faude, O, Radovanović, D, and Stojanović, E. Isokinetic muscle strength in elite soccer players 3 months and 6 months after anterior cruciate ligament reconstruction. J Strength Cond Res 37(4): e297-e304, 2023-The aim of this study was to evaluate interlimb symmetry in quadriceps and hamstring peak torque of elite soccer players at 3 months (stage 1) and 6 months (stage 2) after anterior cruciate ligament (ACL) reconstruction. Eight male professional soccer players competing at the highest level across different European countries, who had undergone ACL reconstruction, participated in this study. All patients underwent a supervised physiotherapy program after surgery. Data analyses included the use of separate two-way repeated-measures analyses of variance and effect sizes. Although knee extensor and flexor strength of the non-injured limb was found to be relatively unaltered ( g = -0.10 to 0.00) between stage 1 and stage 2, comparisons across time points revealed moderate improvements in quadriceps peak torque ( p = 0.01, g = 0.52), hamstring peak torque ( p = 0.07, g = 0.51), and hamstring:quadriceps (H/Q) ratio ( p = 0.03, g = -0.68) of the injured leg, as well as small-large improvements in the quadriceps ( p = 0.004, g = 1.24) and hamstring limb symmetry index (LSI) ( p = 0.056, g = 0.41). A time-dependent moderate-large asymmetry observed at stage 1 between the injured and noninjured leg in quadriceps peak torque ( p < 0.001, g = -1.83), hamstring peak torque ( p = 0.157, g = -0.67), and the H:Q ratio ( p = 0.06, g = 1.01), as well as between the hamstring and quadriceps LSI ( p = 0.03, g = -0.74) was eliminated at stage 2 ( g = -0.31 to 0.42). Our findings indicate the importance of supervised and comprehensive therapy, as well as strength screening to assist in recovery aimed at optimizing identified strength deficits following ACL reconstruction.

Abstract
OBJECTIVE To quantify the incidence rate of anterior cruciate ligament (ACL) injuries and ankle sprains according to player sex, playing level, and exposure setting (training vs. games) in basketball players. METHODS PubMed, MEDLINE, Google Scholar, and ScienceDirect were searched. Only studies reporting the number of ACL injuries and/or ankle sprains alongside the number of athlete-exposures (training sessions and/or games) in basketball players were included. RESULTS Thirty studies (17 reporting ACL injuries and 16 reporting ankle sprains) were included in the meta-analysis. Higher (p < 0.05) ACL injury incidence rates per 1000 athlete-exposures were recorded in females (female: 0.20 95% confidence intervals [0.16-0.25]; male: 0.07 [0.05-0.08]; female-to-male ratio: 3.33 [3.10-3.57]), in players competing at higher playing levels (amateur: 0.06 [0.04-0.09]; intermediate: 0.16 [0.13-0.20]; elite: 0.25 [0.14-0.64]), and in games (games: female, 0.27 [0.21-0.32]; male, 0.06 [0.03-0.08]; training: female, 0.03 [0.02-0.05]; male: 0.01 [0.00-0.02]; game-to-training ratio: 7.90 [4.88-12.91]). Higher (p < 0.05) ankle sprain incidence rates per 1000 athlete-exposures were observed in males (female: 0.82 [0.61-1.03]; male: 0.90 [0.61-1.19]; female-to-male ratio: 0.91 [0.83-0.99]), in players competing at higher playing levels (amateur: 0.54 [0.51-0.57]; intermediate: 1.12 [1.00-1.24]; elite: 1.87 [1.29-2.46]), and in games (games: 2.51 [1.85-3.16]; training: 0.80 [0.52-0.80]; game-to-training ratio: 2.77 [2.35-3.26]). CONCLUSION According to player sex, ACL injury incidence rate is higher in females, while ankle sprain incidence rate is greater in males. ACL injury and ankle sprain incidence rates are greater in players competing at higher playing levels and during games compared to training.

Abstract
The dose-response relationship of sildenafil effects on cardiac function is not completely elucidated. The aim of this study was to assess the effects of different doses of sildenafil on coronary flow and oxidative stress in isolated rat hearts. Coronary flow and markers of oxidative stress, including nitrite outflow, and superoxide anion production in coronary effluent, were determined for isolated rat hearts. The experiments were performed during control conditions and in the presence of sildenafil (10, 20, 50, 200 nM) alone or with Nω-nitro-L-arginine monomethyl ester (L-NAME) (30 μM). Sildenafil was shown to result in a significant increase in coronary flow at lower coronary perfusion pressure (CPP) values at all administered doses, whereas, with an increase in CPP, a reduction in coronary flow was observed. An increase in nitric oxide (NO) was most pronounced in the group treated with the lowest dose of sildenafil at the highest CPP value. After the inhibition of the NO-cyclic guanosine monophosphate (cGMP) signaling (NOS) system by L-NAME, only a dose of 200 nM sildenafil was high enough to overcome the inhibition and to boost release of O2-. That effect was CPP-dependent, with statistical significance reached at 80, 100 and 120 mmHg. Our findings indicate that sildenafil causes changes in heart vasculature in a dose-dependent manner, with a shift from a vasodilatation effect to vasoconstriction with a pressure increase. The highest dose administered is capable of producing superoxide anion radicals in terms of NOS system inhibition.

Abstract
Maternal mental health may be considered a determining factor influencing fetal and child development. An essential factor with potentially negative consequences for a child's psychophysiological development is the presence of maternal distress during pregnancy and the postpartum period. The review is organized and presented to explore and describe the effects of anxiety, stress, and depression in pregnancy and the postpartum period on adverse child developmental outcomes. The neurobiology of maternal distress and the transmission mechanisms at the molecular level to the fetus and child are noted. In addition, the paper discusses the findings of longitudinal studies in which early child development is monitored concerning the presence of maternal distress in pregnancy and the postpartum period. This topic gained importance in the COVID-19 pandemic context, during which a higher frequency of maternal psychological disorders was observed. The need for further interdisciplinary research on the relationship between maternal mental health and fetal/child development was highlighted, especially on the biological mechanisms underlying the transmission of maternal distress to the (unborn) child, to achieve positive developmental outcomes and improve maternal and child well-being.

Abstract
OBJECTIVE This study was undertaken to (1) describe the cardiac structure and function and (2) to quantify the relationships between 25-hydroxyvitamin D [25(OH)D] and echocardiographic parameters in female basketball players. DESIGN A cross-sectional experimental design. SETTING Controlled laboratory setting. PARTICIPANTS Professional, female basketball players (n = 18). INTERVENTION 25(OH)D and echocardiographic screening at the midpoint of the in-season phase, over a 2-week period in late Fall. MAIN OUTCOME MEASURES 25(OH)D and echocardiographic parameters. RESULTS A high prevalence of vitamin D insufficiency was observed in the female players examined (77.8%), with most also displaying eccentric cardiac hypertrophy (77.8%). Nonsignificant, moderate correlations were found between 25(OH)D and structural echocardiographic parameters, including left atrium diameter (r = 0.34, P = 0.16), left ventricular (LV) end-systolic diameter (r = -0.46, P = 0.06), posterior wall thickness (r = 0.36, P = 0.14), LV mass (r = 0.30, P = 0.23), and LV index (r = 0.33, P = 0.18). Significant, large correlations were found between 25(OH)D and echocardiographic parameters indicative of systolic function, including LV ejection fraction (r = 0.59, P = 0.01), fractional shortening (r = 0.59, P = 0.01), and peak systolic mitral tissue velocity (r = 0.51, P = 0.003). Similarly, a significant, large correlation was found between 25(OH)D and diastolic function as indicated by mitral valve inflow deceleration time (r = 0.51, P = 0.03). CONCLUSIONS Our findings suggest the importance of female basketball players maintaining 25(OH)D concentration, given its possible physiological benefits on cardiac structure and function.

Abstract
This study assessed the effect of a 6-month walking program on biochemical parameters in patients with type-2 diabetes mellitus. A group of 40 sedentary patients with type-2 diabetes volunteered to participate in this study. Plasma glucose, triglyceride, total cholesterol, low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase, urea, creatinine, uric acid, C-reactive protein (CRP), and erythrocyte sedimentation rate were measured. Differences in outcome measures between pre- and post-intervention were assessed using paired t-test or Wilcoxon signed-rank test, with effect sizes interpreted separately for normally (µ2: small 0.01-0.06, moderate 0.061-0.14, and large >0.14) and non-normally distributed data (r: small = 0.1-0.3, moderate = 0.3-0.5, and large >0.5). Significant (p < 0.001) large decrease between the initial and final measurements was observed for glucose (r = 0.62), total cholesterol (µ2 = 0.88), triglycerides (r = 0.62), LDL (r = 0.61), AST (µ2 = 0.82), ALT (µ2 = 0.79), gamma-glutamyl transferase (µ2 = 0.79), urea (µ2 = 0.92), creatinine (r = 0.62), uric acid (r = 0.62), CRP (µ2 = 0.80), and erythrocyte sedimentation rate (µ2 = 0.58). On the other hand, significant (p < 0.001) large increase between the initial and final measurements was observed for HDL (r = 0.62). Supervised 6-month aerobic walking program is an effective strategy in (1) reducing hyperglycemia; (2) increasing HDL and reducing LDL, and triglycerides; (3) reducing plasma biomarkers of liver dysfunction, kidney dysfunction, and inflammation in type-2 diabetic patients.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Medicinal properties of hyssop have been used in traditional medicine since ancient times, inter alia, in diseases/conditions with an inherent inflammatory process. AIM OF THE STUDY Accordingly, the aim of this study was to investigate the anti-inflammatory properties of hyssop herb preparations (essential oil and methanol extracts) in vivo, in vitro and in silico. MATERIALS AND METHODS For in vitro testing of essential oils and extracts of hyssop herb, the cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzyme assays were used. In vivo anti-inflammatory potential of the extracts (at doses of 50, 100 and 200 mg/kg) was assessed using the carrageenan-induced rat paw edema test. Molecular docking and dynamics were used for in silico testing of the inhibitory activity of chlorogenic (CA) and rosmarinic (RA) acids, as the dominant compounds in the tested methanol extracts against COX-1 and COX-2 enzymes. RESULTS Significant inhibitory activity was shown in the COX-2 test regarding extracts (essential oils did not exhibit any significant activity). Namely, all analyzed extracts, at a concentration of 20 μg/mL, showed a percentage of inhibition of COX-2 enzyme (54.04-63.04%), which did not indicate a statistically significant difference from the positive control of celecoxib (61.60%) at a concentration of 8.8 μM. In vivo testing showed that all methanol extracts of hyssop herb, at the highest test dose of 200 mg/kg in the third and fourth hours, after carrageenan administration, exhibited a statistically significant (p < 0.05) inhibitory effect on the increase in rat paw edema in relation to control. This activity is comparable or higher in relation to the reference substance, indomethacin, at a concentration of 8 mg/kg. The preliminary in silico results suggest that investigated compounds (RA and CA) showed better inhibitory activity against COX-1 and COX-2 than standard non-steroidal anti-inflammatory drug (NSAID), ibuprofen, as evident from the free binding energy (ΔGbind in kJ mol-1). The binding energies of the docked compounds to COX-1 and -2 were found to be in the range between -47.4 and -49.2 kJ mol-1. Ibuprofen, as the one NSAID, for the same receptors targets, showed remarkably higher binding energy (ΔGbind = -31.3 kJ mol-1 to COX-1, and ΔGbind = -30.9 kJ mol-1 to COX-2). CONCLUSION The results obtained not only support the traditional use of hyssop herb in inflammatory conditions in folk medicine, but also open the door to and the need for further in vivo testing of extracts in order to examine the molecular mechanism of anti-inflammatory activity in living systems and possibly develop a new anti-inflammatory drug or supplement.

Abstract
Background/Aim: Optimal intake of magnesium minerals is essential in maintaining the coordinated physiological functions of cells, tissues and organs. The importance of this element is reflected in the fact that it is the fourth most abundant cation in the human body, participating as a cofactor in more than three hundred enzymatic reactions. Its presence is necessary for the proper functioning of a number of vital functions, such as glycaemic control, the work of the heart and the vascular system and it can potentially play a role in the regulation of body weight. Aim of this study was to investigate the effects of subchronic intake of magnesium hydrocarbonate-rich water on changes in body weight, organ weight and cardiovascular variables in rats with streptozotocin-induced diabetes. Methods: Wistar rats (n = 28) were divided into 4 groups: two control groups, on tap water (TW-C, n = 7) and magnesium hydrocarbonate-rich water (MW-C, n = 7); and two experimental groups with streptozotocin-induced diabetes, on tap water (TW-DM, n = 7) and magnesium hydrocarbonate-rich water (MW-DM, n = 7). The values of body weight, organ weight and cardiovascular parameters were compared after 6 weeks between control groups of rats on subchronic treatment with tap water (TW-C) and magnesium hydrocarbonate-rich water (MW-C) and between groups with streptozotocin-induced diabetes on tap water (TW-DM) and with magnesium hydrocarbonate-rich water (MW-DM). Results: By comparing the values of cardiovascular parameters between groups, significant (p < 0.05) positive effects of magnesium hydrocarbonate-rich water were registered on the values of systolic and pulse blood pressure in diabetic rats fed with magnesium hydrocarbonate-rich water (MW-DM) compared to those fed with tap water (TW-DM). In contrast, no significant effect of magnesium hydrocarbonate on changes in body weight and organ weight was observed. Conclusion: Based on the results, the beneficial effects of magnesium hydrocarbonate-rich water in the regulation of blood pressure can be clearly observed. Potential effects on other cardiovascular variables and body weight and organ weight should be further investigated.

Abstract
Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder characterized by persistent deficits in social communication and social interaction across multiple contexts and restricted, repetitive patterns of behavior, interests and activities. The maternal status of polyunsaturated fatty acids (PUFA) regulates microglial activity and neuroinflammatory pathways during a child's brain development. In children with ASD, the metabolism of PUFA is thought to be deficient or abnormal, leading to increased production of proinflammatory cytokines, increased oxidative stress and an imbalance in the formation and action of neurotransmitters. In addition, nutritional deficits in omega-3 PUFA may affect gut microbiota and contribute to ASD by the gut-brain axis. The aim of this study was to review the possible role of neuroinflammation in ASD development and the effect of omega-3 PUFA supplementation in children with ASD. Due to a wide heterogeneity across RCTs, no definitive conclusion about omega-3 PUFA effects in ASD can be drawn. Supplementation with PUFA could be considered as one of the aspects in regulating the biological status of the organism and could provide added value to standard medical and psychological interventions for reducing behavioral deficits.

Abstract
This study aimed to investigate the effect of vitamin D3 supplementation at a dose of 4,000 IU/day for 6 weeks on serum levels of: 25-hydroxyvitamin D [25(OH)D], bone turnover [osteocalcin and carboxy-terminal telopeptides of crosslinks of type I collagen (CTx-I)], and muscle damage [lactate dehydrogenase (LDH) and creatine kinase (CK)] in middle adolescent (15-18 years) and late-adolescent to early adulthood (19-30 years) female basketball players with inadequate vitamin D status. Participants (N=24) were randomly assigned in a double-blind manner into a vitamin D or placebo group. Data were analyzed using separate 2×2x2 mixed ANOVAs with one within-subjects factor (time) and two between-subjects factors (condition and age). When a significant interaction was observed, the intra-group changes were assessed using paired t tests and Hedge's g. Paired t-tests comparing intra-group changes in the vitamin D condition revealed a non-significant large improvement in 25(OH)D (p = 0.06; g = 0.86), non-significant small decreases in CTx-I (p = 0.13; g = -0.22) and CK (p = 0.07; g = -0.26), as well as a significant moderate decrease in LDH (p = 0.004; g = -0.74). Paired t-tests comparing intra-group changes in the placebo condition revealed a significant moderate decline in 25(OH)D (p <0.001; g = -0.77), as well as significant small increases in CTx-I (p = 0.04; g = 0.47) and CK (p = 0.04; g = 0.36). Vitamin D3 supplementation at 4,000 IU/day could be effective in reducing bone resorption and muscle damage in female basketball players with inadequate baseline vitamin D, irrespective of age.

Abstract
CONTEXT Despite growing interest in quantifying and correcting vitamin D inadequacy in basketball players, a critical synthesis of these data is yet to be performed to overcome the low generalizability of findings from individual studies. OBJECTIVE To provide a comprehensive analysis of data in basketball pertaining to (1) the prevalence of vitamin D inadequacy; (2) the effects of vitamin D supplementation on 25-hydroxyvitamin D [25(OH)D] concentration (and its association with body composition), bone health, and performance; and (3) crucial aspects that warrant further investigation. DATA SOURCES PubMed, MEDLINE, ERIC, Google Scholar, SCIndex, and ScienceDirect databases were searched. STUDY SELECTION After screening, 15 studies were included in the systematic review and meta-analysis. STUDY DESIGN Systematic review and meta-analysis. LEVEL OF EVIDENCE Level 3. DATA EXTRACTION The prevalence of vitamin D inadequacy, serum 25(OH)D, body composition, stress fractures, and physical performance were extracted. RESULTS The pooled prevalence of vitamin D inadequacy for 527 basketball players in 14 studies was 77% (P < 0.001; 95% CI, 0.70-0.84). Supplementation with 4000 IU/d and 4000 IU/wk (absolute mean difference [AMD]: 25.39 nmol/L; P < 0.001; 95% CI, 13.44-37.33), as well as 10,000 IU/d (AMD: 100.01; P < 0.001; 95% CI, 70.39-129.63) vitamin D restored 25(OH)D to normal concentrations. Body composition data revealed inverse correlations between changes in serum 25(OH)D (from pre- to postsupplementation) and body fat (r = -0.80; very large). Data concerning positive impacts of vitamin D supplementation on bone health and physical performance remain sparse. CONCLUSION The high proportion of vitamin D inadequacy underscores the need to screen for serum 25(OH)D in basketball players. Although supplementation restored vitamin D sufficiency, the beneficial effects on bone health and physical performance remain sparse. Adiposity can modulate 25(OH)D response to supplementation.

Abstract
Hyssopus officinalis L. is a well-known aromatic plant used in traditional medicine and the food and cosmetics industry. The aim of this study is to assess the antioxidant, genotoxic, antigenotoxic and cytotoxic properties of characterized hyssop essential oils and methanol extracts. Chemical composition was analyzed by gas chromatography - mass spectrometry (GC-MS) and liquid chromatography with diode array detection and mass spectrometry (LC-DAD-MS), respectively. Antioxidant activity was examined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing/antioxidant power (FRAP) tests; genotoxic and antigenotoxic activity were examined by the comet assay, while cytotoxicity was evaluated by the 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide dye (MTT) test against tumor cell lines (SW480, MDA-MB 231, HeLa) and non-transformed human lung fibroblast cell lines (MRC-5). The essential oils were rich in monoterpene hydrocarbons (e.g., limonene; 7.99–23.81%), oxygenated monoterpenes (1,8-cineole; 38.19–67.1%) and phenylpropanoids (methyl eugenol; 0.00–28.33%). In methanol extracts, the most abundant phenolics were chlorogenic and rosmarinic acid (23.35–33.46 and 3.53–17.98 mg/g, respectively). Methanol extracts expressed moderate to weak antioxidant activity (DPPH IC50 = 56.04–199.89 µg/mL, FRAP = 0.667–0.959 mmol Fe2+/g). Hyssop preparations significantly reduced DNA damage in human whole blood cells, induced by pretreatment with hydrogen peroxide. Methanol extracts exhibited selective and potent dose- and time-dependent activity against the HeLa cell line. Results of the current study demonstrated notable H. officinalis medicinal potential, which calls for further investigation.

Abstract
In a series of our previous works, we revealed the beneficial effects of applied soy isoflavones (genistein or daidzein) on the wide context of corticosteroidogenesis in vivo, in a rat model of the andropause. Soy isoflavones decreased the circulating levels of pituitary adrenocorticotropic hormone, inhibited aldosterone secretion, as well as corticosterone production and secretion, but stimulated dehydroepiandrosterone secretion, all in andropausal rats. In vitro studies indicate that the mechanism underlying these hormonal changes relies on inhibition of the pituitary tyrosine kinase and adrenocortical 3β-hydroxysteroid dehydrogenase enzymes by soy isoflavones. Although the clinical studies are in their infancy, the opinion is that genistein and daidzein have therapeutic potential for the safe treatment of ageing-caused androgen deprivation and glucocorticoid excess with related metabolic/hemodynamic issues in males. Our accumulated experience and knowledge in the field of biomedical effects of plant polyphenols have provided a platform for potential recommending the agenda to organize and accelerate experimental research aimed at producing the optimal supplementation. We hypothesize that an in vivo approach should first be exploited in the sequence of investigative steps, followed by in vitro studies and synchronously conducted molecular docking analyses. In vivo research, besides establishing the margin of exposure safety or adjustment of the correct polyphenol dose, enables identification and quantification of the metabolites of applied polyphenols in the blood. Subsequent in vitro exploitation of the metabolites and related docking analyses provide clarification of the molecular mechanisms of action of applied polyphenols. Chemical modification of the polyphenol structure or coupling it with nanoparticles might be the next step in optimizing the design of supplementation. Selected, intact or chemically-modified polyphenol molecules should be included in preclinical studies on a more closely-related species, while clinical studies would finally assess the safety and effectiveness of a polyphenol-based remedial strategy. The final supplement represents a product of an appropriate technological process, conducted in accordance with the recommendations derived from the preceding research.

Abstract
AIM To compare echocardiographic parameters between female powerlifters, fitness-oriented athletes, and sedentary controls. METHODS A between-subject, cross-sectional experimental design was adopted. Echocardiographic parameters were measured in female powerlifters (n = 10; progressive overload 60%-95% of 1 repetition maximum [RM]), fitness-oriented athletes (n = 10; 50%-70% of 1-RM), and sedentary control subjects (n = 10). Comparisons were made with Kruskal-Wallis tests, one-way analyses of variance, and eta-squared (η2 ) interpreted as small = 0.01-0.06, moderate = 0.061-0.14, and large >0.14. RESULTS Large differences (P > .05) were observed between resistance-trained groups and sedentary controls, whereby relative wall thickness (RWT) and left ventricular (LV) index were greater in powerlifters (RWT: 0.40 ± 0.05, η2 = 0.15; LV index: 95.6 ± 13.6 g/m2 , η2 = 0.15) and fitness-oriented athletes (RWT: 0.40 ± 0.05, η2 = 0.15; LV index: 97.9 ± 14.2 g/m2 , η2 = 0.20) compared to sedentary controls (RWT: 0.36 ± 0.05; LV index: 85.9 ± 10.3 g/m2 ). Large differences were observed in intra-ventricular septal wall thickness (ISWT) and late diastolic velocity (a') between groups, whereby powerlifters exhibited lower a' (8.6 ± 1.2 cm/s) compared to fitness-oriented athletes (9.9 ± 0.9 cm/s, η2 = 0.26, P = .04) and sedentary controls (9.6 ± 0.9 cm/s, η2 = 0.19, P > .05), while fitness-oriented athletes exhibited greater ISWT (10.1 ± 0.7 mm) compared to sedentary controls (9.4 ± 1.0 mm, η2 = 0.16, P > .05). CONCLUSIONS Differences in cardiac structure between powerlifters, fitness-oriented athletes, and sedentary controls suggest specific cardiac remodeling may occur in response to resistance training, without impairment of cardiac function.

Abstract
There is a plethora of evidence to suggest that Galectin-3 plays an important role in normal functions of mammalian cells, as well as in different pathogenic conditions. This review highlights recent data published by researchers, including our own team, on roles of Galectin-3 in the nervous system. Here, we discuss the roles of Galectin-3 in brain development, its roles in glial cells, as well as the interactions of glial cells with other neural and invading cells in pathological conditions. Galectin-3 plays an important role in the pathogenesis of neuroinflammatory and neurodegenerative disorders, such as multiple sclerosis, Alzheimer’s disease, Parkinson’s disease, and Huntington’s disease. On the other hand, there is also evidence of the protective role of Galectin-3 due to its anti-apoptotic effect in target cells. Interestingly, genetic deletion of Galectin-3 affects behavioral patterns in maturing and adult mice. The results reviewed in this paper and recent development of highly specific inhibitors suggests that Galectin-3 may be an important therapeutic target in pathological conditions including the disorders of the central nervous system.

Abstract
Methionine is the precursor of homocysteine, a sulfur amino acid intermediate in the methylation and transsulfuration pathways; methionine-rich diets were used to induce hyperhomocysteinemia, and cardiovascular pathology was often observed. Other sulfur amino acids interfere with this metabolism, i.e., L-cysteine (Cys) and N-aceyl-L-cysteine (NAC), and probably also affect cardiovascular system. Their effects are controversial due to their ability to act both as anti- or pro-oxidant. Thus, this study aimed to elucidate their influence on levels of homocysteine, folate and vitamin B12, levels of different haemostatic parameters (fibrinogen, D-dimer, vWF Ag, vWF Ac) in rat serum or plasma as well as their effects on cardiac and aortic tissue histology in subchronically methionine-treated rats. Wistar albino rats were divided into 4 experimental groups: (a) control group (0.9% sodium chloride 0.1-0.2 mL/day) (n = 10) (K); (b) DL-methionine (0.8 mmol/kg/bw/day) (n = 10) (M); (c) DL-methionine (0.8 mmol/kg/bw/day) + L-cysteine (7 mg/kg/bw/day) (n = 8) (C); (d) DL-methionine (0.8 mmol/ kg/bw/day) + N-acetyl-L-cysteine (50 mg/kg/bw/day) (n = 8) (N). All substances were applied i.p., treatment duration 3 weeks. Lower levels of vitamin B12 in all the groups were found. Folate was reduced only in N group. Decreased fibrinogen was noted in C and N groups and increased D-dimer only in C. VWF activity was reduced in M and C groups. Deleterious effects in heart were observed, especially after Cys and NAC application. Aortic tissue remained unchanged. In conclusion, it could be said that sulfur amino acids have the significant impact on cardiovascular system in subchronically methionine-treated rats. This study points out the relevance of their complex interactions and deleterious effects mediated by either direct influence or procoagulant properties.

Abstract
Taking into consideration that a high concentration of oxygen can express toxic effects due to production of reactive oxygen species (ROS), the aim of our investigation was to establish the influence of hyperbaric oxygenation on oxidative stress parameters and antioxidant enzymes in patients with diabetes mellitus (DM) type 2. Investigation included 50 patients with DM type 2 divided into two groups. The first group consisted of 25 patients, mean age 70 years, mean duration of illness 12 years and without manifest peripheral vascular complications (Wagner 0). The second group consisted of 25 patients, mean age 74 years, mean duration of illness 17 years and with manifest peripheral vascular complications (Wagner 1-5). All patients underwent the same therapeutic protocol, which included 10 hyperbaric oxygenation therapies, once a day for a duration of 60 minutes, with an average partial oxygen pressure of 1.7 atmospheres absolute (ATA). In blood samples the following parameters of redox balance were determined: levels of nitrites (NO₂-), index of lipid peroxidation (TBARS), superoxide anion radical (O₂-), hydrogen peroxide (H₂O₂) and antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT). Our results clearly show that hyperbaric oxygen (HBO₂) therapy does not have a pro-oxidative effect. Additionally, it seems that this procedure strongly mobilized the antioxidant enzyme system, thus improving defense from oxidative damage. All significant data are marked as P ⟨0.05. Our results have shown that in terms of ROS production, HBO₂ can be safe to use in patients suffering from DM type 2 with or without vascular complications.

Abstract
BACKGROUND Intensive exercise changes physiological need for glucose and several biochemical pathways responsible for its metabolism response. Among them are those which involve insulin, insulin-like growth factor (IGF-1), and IGF-binding proteins (IGFBPs). Different types and degrees of exercise, as well as an athlete's fitness, may induce a range of responses regarding concentrations and time needed for the alteration. The idea of the work was to find out whether and how insulin/IGF axis responds to additional physical activity in the already trained subjects and if so, is the adaptation potentially beneficial from the aspect of metabolic control. METHODS The effect of 4-week intensive training on campus (preparatory training) on the levels of insulin, IGF-1, and IGFBPs during maximal progressive exercise test (MPET) on a treadmill was compared to the results obtained during MPET conducted after a regular training season of a female elite handball team (n = 17, age: 17 ± 1 years, height: 171 ± 8 cm, weight: 65 ± 8 kg, body mass index: 22 ± 1 kg/m2 at the beginning of the study; there were no significant changes at the end). Serum samples were obtained from players immediately before the test (basal), at the end of the test after reaching the point of maximal oxygen consumption (VO2max), and after recovery. RESULTS The concentration of insulin decreased at VO2max, but remained higher in players after preparatory training (12.2 ± 2.5 mU/L vs. 8.9 ± 4.4 mU/L, p = 0.049). The level of IGFBP-1 decreased in players at VO2max in either case of training, but it remained much higher in tests performed after the preparatory regime than before (p = 0.029). Concentrations of IGF-1, IGFBP-2, -3, and -4 did not change significantly. CONCLUSION The inverse relation between insulin and IGFBP-1 was lost during MPET, as these 2 molecules changed in the same direction. The results obtained suggest less severe stress-induced depression of insulin and IGFBP-1 after preparatory training. But another metabolic mechanism cannot be excluded, and that is potentially impaired insulin sensitivity resulting in higher level of IGFBP-1.

Abstract
BACKGROUND/AIM Some oligoelements are now investigated as possibly having a role in atherosclerosis. The aim of this study was to compare the concentrations of copper and zinc in the serum and carotid plaque and parameters of lipid metabolism in patients with different morphology of carotid atherosclerotic plaque. METHODS Carotid endarterectomy due to the significant atherosclerotic stenosis was performed in 91 patients (mean age 64 ± 7). The control group consisted of 27 patients (mean age 58 ± 9), without carotid atherosclerosis. Atheroscletoric plaques were divided into four morphological groups, according to ultrasonic and intraoperative characteristics. Copper and zinc concentrations in the plaque, carotid artery and serum were measured by atomic absorption spectrophotometry. RESULTS Serum copper concentrations were statistically significantly higher in the patients with hemorrhagic in comparison to those with calcified plaque (1.2 ± 0.9 µmol/L vs 0.7 ± 0.2 µmol/L, respectively; p = 0.021). Zinc concentrations were statistically significantly lower in plaques of the patients with fibrolipid in comparison to those with calcified plaques (22.1 ± 16.3 g/g vs 38.4 ± 25.8 µg/g, respectively; p = 0.024). A negative significant correlation was found for zinc and triglycerides in the serum in all the patients (r = -0.52, p = 0.025). In the control group we also demonstrated a positive significant correlation for low-density lipoprotein cholesterol and copper in the serum (r = 0.54, p = 0.04). CONCLUSION The data obtained in the current study are consistent with the hypothesis that high copper and lower zinc levels may contribute to atherosclerosis and its sequelae as factors in a multifactorial disease. Further studies are necessary in order to conclude whether high concentration of copper and zinc in the serum could be risk factors for atherosclesrosis.

Abstract
The aim of our study was to determine the role and dynamics of oxidative and nitrosative stress, as well as superoxide dismutase (SOD) and catalase activity in the hepatocytes and erythrocytes in early phase of acute lindane intoxication. Male Wistar rats were divided into groups: control, dimethylsulfoxide and lindane-treated groups (L, 8 mg/kg, intraperitoneally). Animals were sacrificed 0.5 and 4 hours after treatment (L(0.5) and L(4) groups, respectively). Oxidative and nitrosative stress parameters and antioxidant enzymes were determined spectrophotometrically. Liver and plasma thiobarbituric acid reactive substances (TBARS) concentration were significantly increased 0.5 after lindane administration (p < .01), with subsequent additional rise within 4 hours (p < .01), while plasma nitrite + nitrate level was significantly higher only 4 hours after lindane treatment. Total liver SOD activity was significantly increased in L(4) group in comparison with control group (p < .01). In conclusion, oxidative and nitrosative stress play an important role in early phase of acute lindane hepatotoxicity. Antioxidant capacity of hepatocytes is partly increased, due to an adaptive increase in SOD activity.

Abstract
Our aim was to investigate the relation between fetal distress and oxidative stress. Fetal distress was associated with increased concentration of superoxide in the fetal blood and with significant increase of the level of H2O2 in both maternal and fetal blood. The activity of superoxide dismutase was increased roughly sixfold (p<0.01) in the maternal (7330 +/- 2240 U/g of hemoglobin in controls (C) and 36811 +/- 16862 U/g in fetal distress (FD)) and fetal blood (C: 5930 +/- 2641 U/g; FD: 41912 +/- 17133 U/g). In contrast, fetal distress was related to a considerable decrease of catalase activity in both maternal (C: 26011 +/- 8811 U/g; FD: 7212 +/- 1270 U/g) and fetal blood (C: 37194 +/- 9191 U/g; FD: 6173 +/- 1965 U/g). From this we concluded that in fetal distress, the maternal and fetal bloods are exposed to superoxide- and H2O2-mediated oxidative stress, which could be initiated by hypoxic conditions in the fetal blood and placenta. A tremendous increase/decrease of the activities of superoxide dismutase/catalase in the blood of women bearing a distressed fetus in comparison to healthy subjects implies that the assessment of superoxide dismutase/catalase activity could be of use for establishing a timely and accurate ante- or intrapartum diagnosis of fetal distress.

Abstract
BACKGROUND/AIM Oxidative stress is a state of disturbed balance between reactive oxygen species (ROS) and reactive nitrogen species (RNS) on the one hand, and antioxidative defense on the other. As a result of oxidative stress we have irreversible changes in cell function leading to pathological tissue changes, development of many diseases and fast aging process. Increased consumption of oxygen during exercise could be the cause of oxidative stress. The aim of the study was to establish oxidative status of elite karate athletes in the state of rest and after the loading, monitoring the parameters of oxidative stress and components of antioxidative defense in a training process. METHODS During training process, a group of 30 elite karate athletes was included in the study of prevalence. They were males, from 16 to 30 years of age. The examination was conducted both in resting condition and after the loading. Oxidative status was determined by the level of superoxide anion radical (O2-), hydrogen peroxide (H2O2) as prooxidants, and enzymes of the antioxidant defanse system: superoxide dismutase (SOD) and catalase (CAT). RESULTS There was a homogenous group of young athletes of normal weight and fats percentage. A significant decrease of O2- after the load was founded, while the levels of H2O2 was significantly increased. Activity of SOD was not significantly changed after exsercise while that of CAT was significantly increased. CONCLUSION In the long run a programmed physical exercise does not lead to oxidative stress, but an excessive physical load may cause its occurrence.

Abstract
The female reproductive system is very sensitive to different harmful environmental factors. A great danger is hidden in an increased use of food additives like monosodium glutamate (MSG). Numerous studies have shown that application of high doses of MSG to different kinds of animals during the neonatal period may cause lesions of neural structures and the retina. Later in adulthood animals exhibit a series of neuroendocrine disorders: a stunted growth, obesity and infertility. The mechanism of MSG action is not well explained yet. We hypothesized that high concentration of MSG could alter permeability of neural membrane for calcium. We studied whether pretreatment with diltiazem prevented the effects of MSG on ovaries in rats. Female rat pups were treated with: 0.9% NaCl, MSG, diltiazem or diltiazem with MSG. MSG treatment resulted in a cystic degeneration of ovaries and irregular and prolonged estrus phase of estrus cycle. The other treated groups of rats had normal ovarian histology and estrus cycle. The pretreatment with diltiazem prevented development of morphological and functional disorders of ovaries. Our results suggest that calcium overloading play an important role in mechanisms of MSG toxicity.

Abstract
INTRODUCTION Kartagener's (or Siewert) syndrome represents a clinical presentation of primary ciliary diskinesia (PCD) with 3 dominant symptoms: bronchiectasiae, chronic sinusitis and situs viscerum inversus totalis or dextrocardia, only. Siewet demonstrated the first case of this clinical phenomenon in 1904, which was recognized by Kartagener in 1933, as a congenital disorder. PCD is an autosomal recessive disease with extensive genetic heterogenity. Dyskinetic or completely absent motiliy of cilia predisposes to recurrent pulmonary and upper respiratory tract infections resulting in bronchiestasis. Also, infections of the middle ear are common due to lack of ciliary movement in the Eustachian tube. Men have reduced fertility due to spermatozoa with absent motility or abnormalities in the ductuli efferentes. CASE REPORT Our case report represents a middle age woman, treated ambulatory for many years as a chronic obstructive pulmonary disease (COPD). The patient noted recurrent upper respiratory tract infections from her childhood, headaches and recurrent sinusitis. Also, she had extrauterine pregnancy, no children, in spite of several arteficial inseminations. Due to the clinical signs of the right heart failure and the described ECG changes, the echocardiographic examination was done, which showed the dextracardia and the ultrasonographic examination of the abdomen revealed the situs inversus, the finding being within the physiological limits. CONCLUSION All data regarding situs viscerum invesrus, supported by CT verification of bronchiectasiae and chronic inflammation of maxillar sinus led us to conclude that the patient suffered from Kartagener's syndrome.

Abstract
Bladder cancer has poor prognosis. Outcome of the treated patients is dependent on correct staging, histologic grade of the tumor, and correctly realized surgical intervention, i.e. radicality of the operation. During the period from 2002. to 2004, on the Department for Urology in Smederevo, 120 patients were surgically treated because of bladder tumors. Of that number, in 34 patients radical cystectomy and derivation by Sygma-Rectum pouch was done. Of these 34 patients, 22 (64.7%) were being followed during the five-years period.

Abstract
The aim of this study was to assess the effects of folic acid on coronary flow and oxidative stress markers with or without non-specific inhibition of nitric oxide synthase by L-NAME in isolated rat hearts. The hearts of male Wistar albino rats (n = 12, age 8 weeks, body mass 180-200 g) were retrograde perfused according to the Langendorff technique at gradually increased constant perfusion pressure (40-120 cmH2O). Coronary flow and markers of oxidative stress: nitrite outflow, superoxide anion production, and index of lipid peroxidation (by measuring thiobarbituric acid reactive substances) in coronary effluent were calculated. The experiments were performed during control conditions and in presence of folic acid (100 microM) alone or folic acid (100 microM) plus L-NAME (30 microM). Control values of coronary flow varied in range from 4.37 +/- 0.10 ml/min/g wt at 40 cmH2O to 12.05 +/- 0.42 ml/min/g wt at 120 cmH2O. Nitrite outflow varied from 1.68 +/- 0.17 nmol/min/g wt at 40 cmH2O to 3.56 +/- 0.17 nmol/min/g wt at 120 cmH2O and was parallel with coronary perfusion pressure-coronary flow curve. Folic acid significantly increased coronary flow (40-120 cmH2O, 5.63 +/- 0.10 ml/min/g wt and 15.2 +/- 0.42 ml/min/g wt, respectively) and was accompanied by significant increase in nitrite outflow (2.28 +/- 0.29 nmol/min/g wt at 40 cmH2O to 6.66 +/- 0.50 nmol/min/g wt at 120 cmH2O). In addition, folic acid significantly decreased superoxide anion production especially at upper coronary perfusion pressure values (60% at 120 cmH2O) and increased index of lipid peroxidation (37.16% at 120 cmH2O), respectively. Folic acid plus L-NAME did not change control values of coronary flow significantly. However, folic acid plus L-NAME increased nitrite outflow especially at upper coronary perfusion pressure values (43.05% at 120 cmH2O) and did not change significantly superoxide anion production or index of lipid peroxidation versus control values, respectively. The results clearly showed that on isolated rat hearts at gradually increased constant perfusion pressure, folic acid increased coronary flow, increased nitrite outflow, decreased superoxide anion production, and increased index of lipid peroxidation. These effects were reversed or blocked by L-NAME thus demonstrating mediation or at least participation of NO in the mechanism of the folic acid-induced effects.

Abstract
The pharmacokinetics of a new verapamil retard tablet formulation have been investigated in a randomized cross-over bioequivalence study on 12 healthy subjects. The drug was given orally at a single new or standard retard tablet dose of 240mg and at a single intravenous dose of 5mg. Plasma verapamil concentrations were determined by HPLC. New retard tablets produced peak plasma verapamil concentrations of 81.34+/-5.69microg/l, time to peak plasma concentrations of 4.91+/-0.89h and an AUC (0-24h) of 1291+/-103.4h x microg/l, with a terminal phase half-life of 55.1+/-14.9h. After intravenous administration verapamil exhibited biphasic elimination kinetics with a terminal plasma half-life of 2.36+/-0.42h and systemic clearance of 34.32+/-5.81 l/h. Bioavailability of the new peroral retard formulation ranged from 19.49+/-4.41% to 67.69+/-11.70%. Absorption rates and amounts were evaluated by means of the spline-convolutional method. Input rates for the new verapamil retard formulation ranged from 0.77+/-0.20mg/h to 5.57+/-1.58mg/h. The cumulative amount of verapamil input was 39.17+/-9.71% for the new retard tablets. All pharmacokinetic parameters for the new verapamil retard tablet formulation, were in reasonable agreement with the data obtained on already registered verapamil retard formulations, indicating their bioequivalence.

Abstract
It has been shown that common carotid intima-media thickness (CCA-IMT) is a useful outcome measure in clinical studies and intervention trials reflecting early stage of atherosclerosis and cardiovascular risk. The present study examined the association between CCA-IMT and incident ischemic stroke and its subtypes in 75 cases and 21 controls. Cases with ischemic brain infarctions (IBI) were consecutively recruited and classified into subtypes by CT and Bamford's classification (the size and site of infarct) like total anterior circulation infarcts (TACIs), partial anterior circulation infarcts (PACIs), posterior circulation infarcts (POCIs) or lacunar infarcts (LACIs). Controls were recruited among individuals hospitalized at the same institutions and matched for age and sex. Patients and control subjects underwent B-mode ultrasonographic measurements of IMT of the distal wall of both common carotid arteries. Of 75 patients with an acute ischemic stroke, 10 (14%) were classified as TACIs, 34 (45%) with PACIs, 12 (16%) with POCIs and 19 (25%) with LACIs. Mean CCA-IMT was higher in cases (1.03+/-0.18 mm) than in controls (0.85+/-0.18 mm; p<0.0001). The difference in CCA-IMT between cases and controls was significant and the relation between CCA-IMT and IBI remained after adjustment for main cardiovascular risk factors. Regarding the subtypes of IBI, IMT values were significantly higher in patients with TACIs and PACIs versus those with LACIs and POCIs. An increased CCA-IMT was associated with the all subtypes IBI and was significantly higher in those with anterior circulation infarcts versus posterior circulation and lacunar infarcts.

Abstract
UNLABELLED AGING AS A CARDIOVASCULAR RISK FACTOR: Atherosclerosis is the major cause of mortality in the Western world (>50%) as well as in Serbia and Montenegro (>60%). Atherosclerosis/arteriosclerosis functional and structural vascular changes as a consequence of angina pectoris, myocardial infarction, transient ischemic cerebrovascular attacks, stroke, ischaemic attacks in peripheral circulation and/or thromboembolic complications. Aging, lipids (oxidized LDL), infective agents, inflammation, increased glucose level, hypertension, smoking, increased homocysteine level, oxidative stress etc. are recognized as factors which lead to endothelial dysfunction and cause atherosclerosis. Thus, in response to such attacks endothelium releases different substances like: nitric oxide, prostacyclin, endothelium-derived hyperpolarizing factor (EDHF), endothelin, bradykinin, angiotensin II, free oxygen radicals etc. which could be involved in the pathogenesis of atherosclerosis. Atherosclerosis/arteriosclerosis begins with endothelial vasomotor and anti-thrombotic dysfunction and it is of strategic importance to discover this condition earlier. In regard aging, both higher thickness and stiffness of arterial blood vessels appear following an incidence of cardiovascular diseases. DIAGNOSTIC METHODS Over the last decade non-invasive, echosonographic method for visualization of carotid intima-media thickness (indicator of arteriosclerosis/atherosclerosis) was introduced in clinical practice. However, it is also used to compare brachial artery diameter changes, linear velocity and bloodflow which are estimated during basal conditions, during ischemia, during reactive hyperemia (endothelium/independent phase) as well as with left ventricular mass index. DISCUSSION AND CONCLUSION Due to aging there is a decreased response to reactive hyperemia, increased carotid intima-media thickness and increased left ventricular mass, but there is a lack of time-dependent correlation. First endothelial dysfunction occur twenty years before any manifestations appear--as typical vascular and ventricular remodeling. During this period certain markers, for example homocysteine, and diagnostic procedures are important parts of primary prevention.

Abstract
INTRODUCTION Ampicillins are thought to be the most widely used antibiotics. Although ampicillin is included in the WHO list of essential drugs, its per-oral administration is not recommended, whereas amoxicillin is recommended due to its identical antimicrobial spectrum and better pharmacokinetic characteristics. Instead, per oral form of amoxicillin is recommended because of its identical antimicrobial spectrum and better pharmacokinetic characteristics. MATERIAL AND METHODS Drug utilization evaluation of aminopenicillins (ampicillin and amoxcillin) was performed at the Clinic for Infectious Diseases. Clinical Center of Novi Sad and in the Outpatient Health Care Center, Novi Sad "Liman" (Department of General Practice Children's Health Care Department and Ear, Nose and Throat Department) during one calendar month in the year 2000. RESULTS The use of aminopenicillin was 5.1 Defined Daily Doses per 100 bed-days (5.1 DDD/100 BD) at the Clinic for Infectious Diseases. Ampicillin was used in 37.64% of patients and amoxicillin in 13.13%. In Outpatient Health Care Center (OHCC), Department of General Practice, aminopenicillins were prescribed in 1.02 Defined Daily Doses per 1000 inhabitants per day (DDD/1000 inh/day); ampicillin being prescribed in 24.51% and amoxicillin in 75.49%, and it is an optimal ratio. In Children's Health Care Department, OHCC, in children older than 14 years, aminopenicillins were prescribed in 0.37 pediatric DDD/1000 inh/day (ampicillin 40.5%, amoxicillin 59.5%). In the same department, in the age group between 3 and 14 years it was 0.31 pediatric DDD/1000 inh/day (ampicillin 22.5%, amoxicillin 77.5%), while in the age group from 1 to 3 years there were 0.006 pediatric DDD/1000 inh/day prescribed (amoxicillin 100%). At the Ear, Nose and Throat Department, OHCC aminopenicillins were prescribed in 0.02 DDD/1000 inh/day (amoxicillin 100%). CONCLUSIONS Our research showed a change in habits in regard to prescriptions towards the recommended protocol. Oral administration of ampicillin has decreased, especially in comparison to the earlier period in which it had dominated in our primary health care.

Abstract
An international multicenter study entitled Collaborative Study on Drug Use in Pregnancy (DUP) was initiated in 1987 by the Mario Negri Institute (Milano) and co-sponsored by the WHO Regional Office for Europe (Copenhagen). The study covered the use of medicines during pregnancy, labour and postpartum period. The Novi Sad centre contributed with 296 questionnaires. The aim of the study was to evaluate the pharmacotherapy by means of comparison, to identify problems in a particular settings and to plan actions toward improvement. The prescribing of some medicines in the Novi Sad center was found to be at the extreme, being among the lowest in the use of iron preparations during pregnancy and among the highest in the use of ergot alkaloids in the postpartum period. Educational efforts have been made to change this practice after the conclusion of the study in 1989. Ten years later, in 1999, the same questionnaire was applied to 100 women in the postpartum period in the same nursery, the Department of Obstetrics and Gynecology in Novi Sad. The results have shown a distinct improvement with the increase of iron prescribing during pregnancy and almost complete abandonment of postpartum use of ergot alkaloids. In the second study period some other inconsistencies with accepted therapeutical principles were identified. For example, although the use of analgesics fell from 22.3 to 8%, the selection changed towards the high use of metamizole (noraminophenazone) and no use of paracetamol (acetaminophen). It was concluded that international pharmacoepidemiological studies such as DUP, could substantially contribute to the improvement of pharmacotherapy if followed by appropriate actions in changing the prescribing behaviour of the physicians and information directed to the target population.

Abstract
INTRODUCTION An international study on drug use in pregnancy (DUP) started in 1987. There were 22 countries involved, among which two centers from Yugoslavia: Novi Sad and Zagreb. The investigation in Novi Sad comprised 296 parturients. On the basis of obtained results, education of physicians-gynecologists has been organized. 10 years later, a check-up study of 100 parturients was introduced in order to find out possible changes in the applied pharmacotherapy. MATERIAL AND METHODS An investigation on drug use in pregnancy, delivery and puerperium has been performed at the Department of Obstetrics and Gynecology in Novi Sad. It included 296 parturients in 1989 (1st investigated period) and 100 parturients in 1999 (2nd investigated period). Results obtained in 1999 were compared with the results from 1989. RESULTS AND DISCUSSION Chronic use of drugs was found similar for both investigated periods (2.38% in 1989 vs 5% in 1999). In this group there were no drugs which could endanger the fetus. In 1989, there were 12.6% of pregnant women using preparations such as iron supply, versus 54% in 1999, so that trends in prevention of pharmacotherapy of anemia approached those in developed countries. In the second investigated period there was a significant decrease in progresterone therapy and two times increased use of beta-adrenergic agonists, which is in accordance with new trends in pharmacology. Use of paracetamol decreased, whereas use of metamizole, known by serious side-effects, increased. Drug administration during delivery decreased in 1999 (77%) in relation to 1989 (94.93%) mostly comprising drugs for autonomous nervous system, analgesics and analgoantipyretics. Administration of ergot-alkaloids decreased: from 65.8% in 1989 to 22% in 1999. Use of drugs after delivery can endanger both the parturient and lactation, i.e. nutrition of the newborn infant and consequently the newborn itself. During 1989 practically every parturient (95.27%) was administered drugs, out of which about 97% belonged to the group of ergot-alkaloids which were routinly administered for acceleration of uterine involution. In 1999 ergot-alkaloids were administered only in 9% of delivered women. Use of oxytocins was also reduced because they were administered not routinely but only on purpose. CONCLUSIONS The following conclusions were made on the basis of obtained data: 1. During the first period there was a difference in drug use when compared to the countries with developed pharmacotherapeutic practice. 2. Use of progesterones was remarkably decreased in 1999 versus two times increased use of beta-adrenergic agonists administered in prevention of spontaneous abortions. 3. Use of opiate analgesics during delivery was significantly reduced from 43% to 11% in 1999. 4. In the second investigated period use of iron preparations was significantly increased versus decreased use of ergot-alkaloids. 5. Use of paracetamol decreased, whereas use of metamizole (known by serious side-effects) increased.

Abstract
The effects of Hypericum perforatum L. (Hypericaceae) crude ethanol extract (A), ethyl acetate extract (B), aqueous extract (C) and infusion (I), on pentobarbital induced sleeping time, intestinal motility, and their analgesic activity, have been investigated. Extracts A and B exhibited significant stimulatory and antidepressant effects on the CNS. Both extracts prolonged sleep, increasing time up to more than 25 min. The antidepressive activity of extract A was also achieved by significant reduction of the myorelaxant activity of diazepam. Extract B exhibited strong analgesic activity reducing abdominal stretching induced by acetic acid by nearly 50 %. Extracts A, B and C exhibited spasmolytic activity, significantly reducing intestine motility.
