Abstract
BACKGROUND This study explored the effects of hyperbaric oxygen therapy (HBOT) on the cardiovascular system and oxidative stress in streptozotocin-induced diabetic rats. Wistar albino rats were divided into four groups: DM group (diabetic rats), DM+HBOT group (diabetic rats exposed to HBOT for 1 h daily, five days a week, at 2.8 atmosphere absolute (ATA) with 100% oxygen for two weeks), DM+INS group (diabetic rats treated with neutral protamine hagedorn (NPH) insulin at a dosage of 3-5 U/day), and DM+HBOT+INS group (diabetic rats treated with both NPH insulin and HBOT for two weeks). METHODS Evaluations included glycemic control, oxidative stress parameters, and cardiac function measurements. RESULTS NPH insulin treatment reduced blood glucose levels, although normoglycemia was not achieved. The DM+HBOT+INS group demonstrated the lowest pro-oxidative marker levels. NPH insulin treatment improved cardiac function, and combination therapy effectively restored cardiac function in diabetic animals. CONCLUSIONS NPH insulin treatment reduced hyperglycemia and improved cardiac function in diabetic rats. The combined approach of NPH insulin and HBOT resulted in decreased pro-oxidative markers. These findings provide valuable insights for managing cardiovascular complications and oxidative stress in diabetes.

Abstract
BACKGROUND Research suggests peer support groups can amplify and extend treatment effects and enhance long-term recovery from Alcohol and Other Drug (AOD) problems. However, they are rarely integrated into outpatient treatment programs, resulting in a missed opportunity for peer-to-peer learning, and increased connection to others social networks where people want to reduce or cease substance use. METHOD In this mixed-methods study, we examined the uptake, participant experiences and impacts of Self-Management and Recovery Training (SMART) when embedded in three public AOD treatment programs in a pilot program in Australia. Groups were delivered initially in-person but transitioned online during the COVID-19 pandemic. RESULTS A total of 75 SMART Recovery groups were run by the pilot sites, with an average attendance of 6.5 people per meeting. Among Participants (N = 31) who completed the survey, 94% reported benefits relating to substance use (i.e., reduction/ successful maintenance of abstinence), 71% reported improvements in their mental health and wellbeing, 74% reported improvements in their physical health, and 81% reported feeling better connected with others. In-depth qualitative interviews were conducted with 10 participants to explore their experiences. Thematic analysis revealed four themes: motivation to attend, active ingredients, views on the integration of SMART into formal AOD, and the advantages and disadvantages of online groups. CONCLUSION Taken together, these findings suggest embedding SMART Recovery in AOD treatment is a worthwhile endeavour. This was indicated by a good uptake and evidence of multiple and unique benefits to participants over and above their usual care, notably, better management of their AOD use, health, wellbeing, and sense of connection with others.

Abstract
(1) Background: The aim of this study was to show the effects of swimming and nandrolone administration on cardiodynamic and morphometric parameters of the isolated rat heart. (2) The study included 72 Wistar rats, divided into three groups, scheduled to be sacrificed after the second, third, and fourth week. Each group was divided into four subgroups: control (T-N-), nandrolone (T-N+), swimming training (T+N-), and swimming training plus nandrolone (T+N+) group. The rats from T+N- and T+N+ swam 1 h/day, 5 days/week while ones from T-N+ and T+N+ received weekly nandrolone decanoate (20 mg/kg). The isolated hearts were perfused according to the Langendorff technique and measured parameters: dp/dt max/min, SLVP, DLVP, heart rate, and coronary flow. Hearts were fixed and stained with H/E and Masson trichrome dyes. (3) dp/dt max and dp/dt min were increased in the T-N+ group at higher perfusion pressure compared to the T-N- group. SLVP and DLVP were increased in all groups after the 4th week. Collagen content was increased in T-N+ by 403% and in T+N+ by 357% groups, while it was decreased in T+N- compared to the control after 4th week. (4) Conclusions: Nandrolone alone or combined with swimming had a deleterious effect on myocardial function and perfusion.

Abstract
Ruthenium(II) complexes offer the potential for lower toxicity compared with platinum(II) complexes. Our study aimed to compare cardiotoxicity of [Ru(Cl-tpy)(en)Cl][Cl], [Ru(Cl-tpy)(dach)Cl][Cl], [Ru(Cl-tpy)(bpy)Cl][Cl], cisplatin, and saline through assessment of redox status and relative expression of apoptosis-related genes. A total of 40 Wistar albino rats were divided into five groups. Ruthenium groups received a single dose of complexes intraperitoneally (4 mg/kg/week) for a 4-week period; cisplatin group received cisplatin (4 mg/kg/week) and control group received saline (4 mL/kg/week) in the same manner as ruthenium groups. In collected blood and heart tissue samples, spectrophotometric determination of oxidative stress biomarkers was performed. The relative expression of apoptosis-related genes (Bcl-2, Bax, and caspase-3) in hearts was examined by real-time polymerase chain reaction. Our results showed that systemic and cardiac pro-oxidative markers (thiobarbituric acid reactive substances and nitrite) were significantly lower in ruthenium groups compared with cisplatin group, while concentrations of antioxidative parameters (catalase, superoxide dismutase, and oxidized glutathione) were significantly higher. Ruthenium administration led to significantly lower gene expression of Bax and caspase-3 compared with cisplatin-treated rats, while Bcl-2 remained unchanged. Applied ruthenium complexes have less pronounced potential for induction of oxidative stress-mediated cardiotoxicity compared with cisplatin. These findings may help for future studies that should clarify the mechanisms of cardiotoxicity of ruthenium-based metallodrugs.

Abstract
BACKGROUND Studies have recently examined the role of epigenetic mechanisms in preeclampsia pathophysiology. One commonly examined epigenetic process is DNA methylation. This heritable epigenetic marker is involved in many important cellular functions. The aim of this study was to establish the association between DNA methylation and preeclampsia and to critically appraise the roles of major study characteristics that can significantly impact the association between DNA methylation and preeclampsia. MAIN BODY A systematic review was performed by searching PubMed, Web of Science, and EMBASE for original research articles published over time, until May 31, 2019 in English. Eligible studies compared DNA methylation levels in pregnant women with vs. without preeclampsia. Ninety articles were included. Epigenome-wide studies identified hundreds of differentially methylated places/regions in preeclamptic patients. Hypomethylation was the predominant finding in studies analyzing placental tissue (14/19), while hypermethylation was detected in three studies that analyzed maternal white blood cells (3/3). In candidate gene studies, methylation alterations for a number of genes were found to be associated with preeclampsia. A greater number of differentially methylated genes was found when analyzing more severe preeclampsia (70/82), compared to studies analyzing less severe preeclampsia vs. controls (13/27). A high degree of heterogeneity existed among the studies in terms of methodological study characteristics including design (study design, definition of preeclampsia, control group, sample size, confounders), implementation (biological sample, DNA methylation method, purification of DNA extraction, and validation of methylation), analysis (analytical method, batch effect, genotyping, and gene expression), and data presentation (methylation quantification measure, measure of variability, reporting). Based on the results of this review, we provide recommendations for study design and analytical approach for further studies. CONCLUSIONS The findings from this review support the role of DNA methylation in the pathophysiology of preeclampsia. Establishing field-wide methodological and analytical standards may increase value and reduce waste, allowing researchers to gain additional insights into the role of DNA methylation in the pathophysiology of preeclampsia.

Abstract
This study aimed to assess the impact of high-intensity interval training (HIIT) vs. moderate-intensity continuous training (MIT) on cardiodynamic parameters in isolated rat heart. Wistar albino rats were randomly assigned to groups according to running protocol: sedentary control, MIT, and HIIT; spontaneous hypertensive rat (SHR) sedentary control, SHR + MIT, and SHR + HIIT. HIIT groups performed the running in 5 sprints × 45-55 m/min for 30-90 s, with 2 min of rest after each sprint, while MIT groups performed the running of 10-15 m/min for 1 h with 3 min of rest every 100 m; both protocols were implemented 5 days/week over 4 weeks with 1 week of adaptation before protocols started. Isolated rat hearts were perfused according to Langendorff technique at gradually increased coronary perfusion pressures (40-120 cmH2O). Using a sensor placed in the left ventricle, we registered maximum and minimum rate of pressure development in the left ventricle, systolic and diastolic left ventricular pressure, and heart rate. Coronary flow was measured flowmetrically. MIT was connected with cardiac depression in normotensive conditions, while HIIT leads to cardiac depression in hypertensive rats. HIIT induced more significant increase of contractile and relaxation parameters of the isolated rat heart, especially in hypertensive animals.

Abstract
Abstract
Discovery of the metallopharmaceutical cisplatin and its use in antitumour therapy has initiated the rational design and screening of metal-based anticancer agents as potential chemotherapeutics. In addition to the achievements of cisplatin and its therapeutic analogues, there are significant drawbacks to its use: resistance and toxicity. Over the past four decades, numerous transition metal complexes have been synthesized and investigated in vitro and in vivo. The most studied metals among these complexes are platinum and ruthenium. The key features of these investigations is to find novel metal complexes that could potentially exert less toxicity and equal or higher antitumour potency and to overcome other pharmacological deficiencies. Ru complexes have a different mode of action than cisplatin does, some of which are under clinical trials for treating metastatic or cisplatin-resistant tumours. This review consists of the current knowledge, published and unpublished, related to the toxicity of metallopharmaceuticals, and special attention is given to platinum [Pt(II) and Pt(IV)] and ruthenium [Ru(II) and Ru(III)] complexes.

Abstract
Background Our recent clinical observations put into question the routine hormonal therapy for pneumothorax recurrence prevention, in patients operated for catamenial pneumothorax (CP). Methods Retrospective review of the treatment of four women operated for CP in a recent 32-months period. Results The four presented patients with CP represent 4.8 % of the overall number of patients operated for spontaneous pneumothorax and 19 % of women operated for pneumothorax in the same period. In all patients, typical multiple diaphragm holes existed. The involved part of the diaphragm was removed with diaphragm suture in three patients, whilst in one patient, a diaphragm placation was done. Endometriosis was histologically confirmed in two patients. During the follow-up period of 6–43 months, none of the patients underwent a postoperative hormonal therapy for different reasons, and in none of them the pneumothorax recurrence occurred. Conclusion The clinical course of these patients, with the absence of the pneumothorax recurrence despite the omission of the hormonal treatment, suggests that the appropriateness of the routine hormonal treatment with gonadotrophin-releasing hormone analogues for 6–12 months, should be reconsidered and re-evaluated in further studies.

Abstract
BACKGROUND As an alternative to the modified Stoppa approach, the Pararectus approach is used clinically for treatment of acetabular fractures involving the anterior column. The current study assessed the surgical exposure and the options for instrumentation using both of these approaches. METHODS Surgical dissections were conducted on five human cadavers (all male, mean age 88 years (82-97)) using the modified Stoppa and the Pararectus approach, with the same skin incision length (10cm). Distal boundaries of the exposed bony surfaces were marked using a chisel. After removal of all soft-tissues, distances from the boundaries in the false and true pelvis were measured with reference to the pelvic brim. The exposed bone was coloured and calibrated digital images of each inner hemipelvis were taken. The amount of exposed surface using both approaches was assessed and represented as a percentage of the total bony surface of each hemipelvis. For instrumentation, a suprapectineal quadrilateral buttress plate was used. Screw lengths were documented, and three-dimensional CT reconstructions were performed to assess screw trajectories qualitatively. Wilcoxon's signed rank test for paired groups was used (level of significance: p<0.05). RESULTS After utilization of the Pararectus approach, the distances from the farthest boundaries of exposed bone towards the pelvic brim were significantly higher in the false but not the true pelvis, compared to the modified Stoppa approach. The percentage (mean±SD) of exposed bone accessible after utilizing the Pararectus approach was 42±8%, compared to 29±6% using the modified Stoppa (p=0.011). In cadavers exposed by the Pararectus approach, screws placed for posterior fixation and as a posterior column screw were longer by factor 1.8 and 2.1, respectively (p<0.05), and screws could be placed more posteromedial towards the posterior inferior iliac spine or in line with the posterior column directed towards the ischial tuberosity. CONCLUSION Compared to the modified Stoppa, the Pararectus approach facilitates a greater surgical access in the false pelvis, provides versatility for fracture fixation in the posterior pelvic ring and allows for the option to extend the approach without a new incision.

Abstract
AIM The aim of this retrospective study was to evaluate the frequency and distribution of maxillofacial trauma patients over 80 years, with regard to type and environment of accidents as well as treatment and complications. PATIENTS AND METHODS Data for 94 patients (96 cases; aged 80-94 years) with maxillofacial fractures were retrospectively analysed. RESULTS Data of 30 male and 64 female patients with an average age of 85 years were analysed. In 90% of the study population, the cause of fractures was a fall, followed by traffic accidents (9%) and assault (1%). Seventy-two patients had fractures of the midface, 10 had factures of the mandible, 9 had fractures of both the midface and mandible and 5 had fractures of the neurocranium and midface. Surgical intervention was required in 57% of the patients. Post-operative complications were: four cases of diplopia, two cases of infected plates, four cases of lower eyelid ectropion and in one case a retrobulbar haematoma. CONCLUSION Facial trauma in the elderly can often be treated conservatively unless the patient complains of functional problems. Due to co-morbidities, special attention should be paid to hypertension, anticoagulant agents and the surgical approach.

Abstract
BACKGROUND The Aim of our study was to present and analyze the distribution of cerebrovascular insult types and their localization in patients with normal body temperature by means of computerized tomography, and in those with elevated body temperature by means of neuroradiographic findings. METHODS In our study we evaluated 103 patients that suffered a cerebrovascular insult and were treated at Special Hospital for Cerebrovascular disorders "Saint Sava" in Belgrade. All patients were divided into two groups due to the presence of elevated body temperature. RESULTS Fever as a complication in period after acute cerebrovascular insult is presented in almost every fifth patient. In the group of patients with fever, the most common presentation was acute ischemic cerebrovascular insult, namely in 45.63%, while in the group of patients with normal body temperature, the most common presentation was lacunar infarction, namely in 46.60% of participants. The most frequent localization of cerebrovascular insult is in cortex and subcortex regions. CONCLUSIONS It should be stated that some patients with specific types of cerebrovascular insult as well as their localization are at higher risk for development of complications. This study suggests that appropriate diagnostics as well as prevention and management of in-hospital complications could improve the short-term and long-term prognoses after stroke (Tab. 3, Ref. 14).

Abstract
BACKGROUND The efficiency of denatured muscle grafting in nerve repair has been confirmed in experimental models and animals. The first clinical trials to repair digital nerves and mixed sensory-motor nerves were encouraging regarding sensory recovery but motor recovery was poor, probably because of delayed repair. We present the functional outcome of repair of motor nerves using denatured muscle graft and compare the results with those using standard nerve graft techniques. METHODS This prospective study included 9 radial nerve defects repaired with denatured muscle grafts and 23 radial nerve defects repaired using nerve grafts. Missile induced nerve injury, mid-arm level of lesion, a nerve gap smaller than 6 cm, and a preoperative interval of less than 5 months were characteristics shared by all patients. None of the patients had concomitant vascular injury, severe scarring, or significant soft tissue damage in the region of nerve repair. Motor recovery was estimated with 0-5 points, at least 4.7 years after surgery, according to the BMRC scale. RESULTS A successful outcome (>or=M3) was achieved in 7 out of the 9 patients treated using a muscle graft and in 21 out of the 23 patients treated using nerve grafts (P > 0.05). Excellent recovery and the clinically significant re-establishment of thumb extension (M5 grade) were never achieved in the patients treated using muscle grafts. The average motor score was significantly better in patients treated with nerve grafts than in those who received muscle grafts (3.8 +/- 0.9 and 3.2 +/- 0.8; P = 0.035). With the patients who received muscle grafts, an inverse correlation existed between motor recovery and the length of the nerve gap (P = 0.017). CONCLUSIONS Denatured muscle grafts can be useful for bridging short radial nerve defects, but the quality of recovery is significantly worse than after nerve graft repair. Even if relatively short nerve defects are bridged with denatured muscle grafts, the outcomes correlate inversely with the length of the gap.

Abstract
Strategic lesions of the thalamus interfere with cognitive functions and produce complex neuropsychological symptoms. Bilateral, simultaneous thalamic hemorrhages are unusual causes of thalamic dementia. We present clinical, neuropsychological and structural neuroimaging data of a 12-month follow-up period of a patient with bilateral thalamic hemorrhages. After the operation of pancreatitis acuta hemorrhagico-necroticans, the patient developed coma. Computed tomography (CT) and magnetic resonance (MR) of the brain showed medially situated bithalamic hematomas. During the follow-up period, patient's level of consciousness has improved. Moderate dementia (MMSE 20/30) was found with severe temporal and spatial disorientation. Neuropsychological tests showed that attention and concentration were prominently impaired; there were severe verbal and less prominent, visual memory deficits, with anterograde and retrograde amnesia, accompanied by confabulations. Loss of cognitive flexibility and dysexecutive syndrome were also demonstrated. Dynamic apraxia, visual organization and visual construction deficit and impairment of categorial and phonemic fluency were noted. Language was only moderately impaired (anomia). A year later, neuropsychological profile was similar with moderate improvement of retrograde amnesia, whereas anterograde deficits persisted. Neuropsychological syndrome in our patient with bilateral thalamic hemorrhages was characteristic for subcortico-cortical cognitive deficit and was caused by disruption of the cortico-thalamic circuitry.

Abstract
In the Balkan countries, where trichinellosis is a re-emerging zoonosis, it is of great importance to determine Trichinella infection prevalence among the major hosts, including horses. One method for monitoring prevalence is serological surveillance; however, the validity of serological methods in horses is not well understood. The dynamics of anti-Trichinella IgG production and circulating excretory/secretory (ES) antigens were investigated in three horses experimentally-infected with Trichinella spiralis. Horses were slaughtered at 32 week post infection (p.i.). Low worm burdens were found in all three animals. Anti-Trichinella IgG was detected up to 32 weeks p.i. by an indirect immunofluorescence assay (IFA) and by Western blot (Wb), but not by ELISA. The ELISA test detected antibodies for only a short period of time (up to 18 weeks p.i. using ES antigen or up to 20 weeks p.i. using tyvelose-BSA antigen). The presence of circulating muscle larvae ES antigen in sera of infected horses was observed by dot blot from the 4th week p.i. up to the 32nd week p.i.

Abstract
Implementation of methods to control inspection for Trichinella in meat recommended by International Commission on Trichinellosis (ICT), particularly the introduction of the quality assurance standards and proficiency panels for certified analysts is extremely important in Serbia and other countries where Trichinellosis is endemic. In spite of existing regulations, including the inspection of 0.5 g samples of diaphragm by the compression method or by artificial digestion of 1g samples, in Serbia 280 people were diagnosed with clinical trichinellosis after consumption of inspected meat during the period 2001--2002. These outbreaks, which occurred in the municipalities of Kumane, Surcin and Bogatic, were a consequence of inadequate application of inspection methods and insufficient education of some veterinary inspectors. The problem of inadequate veterinary inspection in Serbia can be overcome by strict application of the ICT recommendations for the control of Trichinella with specific emphasis on implementing the quality assurance system (QAS) and proficiency sampling (PS/--PP/panel).

Abstract
A discovery in 2002 of a Trichinella spiralis-infected horse in Serbia offered an opportunity to conduct needed epidemiological studies on how horses, considered herbivores, acquire a meat-borne parasite. This enigma has persisted since the first human outbreaks from infected horse meat occurred in then 1970s. The trace back of the infected horse to a farm owner was carried out. Interviews and investigations on the farm led to the conclusion that the owner had fed the horse food waste in order to condition the horse prior to sale. Further investigations were then carried out to determine the frequency of such practices among horse owners. Based on interviews of horse producers at local horse markets, it was revealed that the feeding of animal products to horses was a common practice. Further, it was alleged that many horses, particularly those in poor nutritional condition would readily consume meat. A subsequent series of trials involving the experimental feeding of 219 horses demonstrated that 32% would consume meat patties. To confirm that horses would eat infected meat under normal farm conditions, three horses were offered infected ground pork balls containing 1100 larvae. All three became infected, and at necropsy at 32 weeks later, were still positive by indirect IFA testing, but not by ELISA using an excretory-secretory (ES) antigen. This result indicates that further study is needed on the nature of the antigen(s) used for potential serological monitoring and surveillance of horse trichinellosis, especially the importance of antigenic diversity. The experimentally-infected horses also had very low infection levels (larvae per gram of muscle) at 32 weeks of infection, and although the public health consequences are unknown, the question of whether current recommended inspection procedures based on pepsin digestion of selected muscle samples require sufficient quantities of muscle should be addressed. It is concluded that horses are more willing to consume meat than realized and that the intentional feeding of animal products and kitchen waste is a common occurrence among horse owners in Serbia (and elsewhere?). This is a high risk practice which demands closer scrutiny by veterinary and food safety authorities, including the implementation of rules and procedures to ensure that such feeds are rendered safe for horses, as is now required for feeding to swine.

Abstract
It is known that, depending on the concentration, treatment with urea could improve skin barrier function, despite its penetration-enhancing properties. This controversial skin effect of urea has been explored systematically in this study in terms of the effect of vehicle on the performance of urea. In the first part, a series of four semi-solid emulsions with 5% (w/w) urea, varying in the type of emulsion, nature of emulsifier and polarity of oil ingredients, have been evaluated with regard to their skin hydrating and transepidermal water loss (TEWL)-modifying properties. Placebo samples were tested alongside the urea-containing ones. Two best performing moisturisers from the above were chosen for the second part of the study, in which sodium lauryl sulphate (SLS)-irritated skin was treated with both placebo and urea-containing samples. In addition to TEWL and skin hydration level, the erythema index (EI) was measured before, during and after the treatment. The results have shown that barrier-improving and hydrating abilities of urea are bi-directional and dependent on both the type of vehicle used for its delivery and the state of skin.

Abstract
The most important safety measure for prevention of CO poisoning is the installation of automatic systems that signal high CO concentrations in the work environment. Public health measures that include stringent pollution control, introduction of low-cost CO monitors, and public education aimed at the high-risk population (e.g., new workers, drivers) should decrease the number of deaths from CO poisoning and should save productive years of life. Toxicity of CO is a consequence of tissue hypoxia created by the displacement of oxygen from hemoglobin and the subsequent impairment of oxygen release to the tissues. Early symptoms of CO intoxication are insidious and can resemble other diseases; physical examination may be unremarkable. For these reasons, many cases of CO poisoning are not readily recognized.

Abstract
We have shown previously that the esters of adenosine-5'-carboxylic acid (10) represent a new class of potent nontoxic coronary vasodilators. For example, the ethyl ester (12), which is active by an intraduodenal or intravenous route in dogs, causes a large increase in coronary sinus PO2 and coronary blood flow. Because of the pronounced vasoactive properties of the esters of adenosine-5'-carboxylic acid, a systematic study of the corresponding amides (14--50) was undertaken. In addition, several other analogues containing the N1-oxide function (51--52) or 2',3' substituents (3--9, 53--54) were studied.
