Abstract
The study aimed to uncover a unique aspect of obesity-related metabolic disorders in the testicles induced by a high-fat diet (HFD) and explored the potential mitigating effects of exercise modalities on male fertility. Thirty mature male Wistar rats were randomly assigned to control, HFD-sole, moderate-intensity exercise with HFD (HFD+MICT), high-intensity continuous exercise with HFD (HFD+HICT), and high-intensity interval exercise with HFD (HFD+HIIT) groups (n=6/group). Intracytoplasmic carbohydrate (ICC) storage, expression levels of GLUT-1, GLUT-3, MCT-4, Igf1, and Igf1R, and testicular lactate and lactate dehydrogenase (LDH) levels were assessed. ICC storage significantly decreased in HFD-sole rats, along with decreased mRNA and protein levels of GLUT-1, GLUT-3, MCT-4, Igf1, and Igf1R. The HFD-sole group exhibited a notable reduction in testicular lactate and LDH levels (p<0.05). Conversely, exercise, particularly HIIT, upregulated ICC storage, expression levels of GLUT-1, GLUT-3, MCT-4, Igf1, and Igf1R, and enhanced testicular lactate and LDH levels. These results confirm that exercise, especially HIIT, has the potential to mitigate the adverse effects of HFD-induced obesity on testicular metabolism and male fertility. The upregulation of metabolite transporters, LDH, lactate levels, Igf1, and Igf1R expression may contribute to maintaining metabolic interactions and improving the glucose/lactate conversion process. These findings underscore the potential benefits of exercise in preventing and managing obesity-related male fertility issues.

Abstract
INTRODUCTION Diabetes mellitus can affect and disrupt the levels of PGC1α and NRF2 proteins in the mitochondrial biogenesis pathway. Considering the anti-diabetic properties of Urtica Dioica extract and exercise, this study aimed to investigate the beneficial effects of Urtica Dioica extract and endurance activity on PGC1α and NRF2 protein levels in the streptozotocin-induced diabetic rat heart tissue. MATERIALS AND METHODS 58 male Wistar rats were divided into five groups (N = 12) including: healthy control (HC), diabetes control (DC), diabetes Urtica Dioica (D-UD), diabetes exercise training (DT), and diabetes exercise training Urtica Dioica (DT-UD). Diabetes was induced intraperitoneally by STZ (45 mg/kg) injection. Two weeks after the induction of diabetes, the rats were stimulated to carry out the exercise (moderate intensity/5day/week) and the gavage of UD extract (50 mg/kg/day) was administered to the rats for six weeks. In this study, the western blotting method was used to measure the levels of PGC1α and NRF2 proteins. Moreover, cardiography was used to evaluate the functional parameters of the heart (ejection fraction & fractional shortening). Finally, the bioluminescence and ELISA methods were used to determine the content of adenosine triphosphate and citrate synthase. RESULTS The cardiac function parameters, the mitochondrial ATP and the CS content in DC group mice were impaired in comparison with the other study groups and showed a decreasing trend (P < 0.001). The treatment with EX + UD extract was able to minimize the rate of these disorders and acted as a protector of mitochondrial function. There were significant differences in the expression levels of NRF2 (F = 17.7, P = 0.001) and PGC-1α (F = 43.7, P = 0.001) mitochondrial proteins among the different groups. The levels of these proteins were significantly reduced in the DC group in comparison with the HC group (P < 0.001). The treatment with EX or UD extract increased the expression of PGC-1α and NRF2 proteins in the heart muscle of animals in the DT and D-UD groups in comparison with the DC group (P < 0.05). Moreover, the expression of these proteins was more pronounced in the DT-UD group. There was not a significant difference between the DT-UD group and the HC group regarding the expression of these proteins (P > 0.05). CONCLUSIONS The results of this study showed that treatment with EX and UD extract could treat the disorders which were caused by diabetes in the parameters of cardiac function. Moreover, it was able to improve the expression of the levels of proteins which were involved in mitochondrial biogenesis and its function. Finally, this kind of treatment could attract more attention to the roles of EX and UD extract in the prevention of cardiovascular complications in future studies.

Abstract
BACKGROUND The aim of this study was to investigate the effect of 8 weeks of aerobic exercise on the expression of mir-126 and some angiogenesis factors in the endothelial tissue of the cardiac muscle of type 2 diabetic rats. METHODS Sixteen male Wistar rats were divided into two groups: diabetic control and diabetic training. Nicotinamide and streptozotocin injections were used to induce type 2 diabetes. After familiarization, the training group participated in an 8-week exercise protocol on a treadmill with an intensity of 25 m per minute, a slope of 5% and 30 min per session. RT-PCR was used to evaluate the expression of mir-126 and PI3K genes. Expression of raf1, VEGF, blood glucose and insulin was determined by ELISA and insulin resistance was assessed by HOMA-IR homeostasis model. Immunohistochemistry was used to measure the capillary density of the cardiac muscle. Data were analyzed by t-test for independent groups with a significance level of p < 0.05. RESULTS Diabetes reduces angiogenesis in cardiac tissue, which is associated with a significant reduction in the expression of mir-126, raf1, VEGF and PI3K; while aerobic exercise increased the expression of mir-126, raf1, PI3K, VEGF. Exercise also decreased blood glucose levels and insulin resistance. CONCLUSION It seems that aerobic exercise can prevent the destructive effects of diabetes by activating the angiogenic pathway of cardiac tissue. Therefore, regulatory processes through mir-126, which are influenced by aerobic exercise, can be a valuable strategy in developing new treatments for diabetes.

Abstract
Objective The current research was designed to analyze the effect of moderate-intensity exercise training (MEXT),
solely and simultaneous with insulin, on the network between oxidative stress and Hsp70 and Hsp90 chaperones after
experimental type I diabetes (DM) induction in rats.
Materials and Methods In the experimental study, 36 mature Wistar rats were assigned into control and experimental
type I DM-induced groups, and then the diabetic animals were categorized to sedentary type I DM-induced (SDM),
exercise training-sole without DM (E), exercise training DM-induced (EDM), insulin-treated sedentary DM-induced
(ISDM), and exercise training insulin-treated DM-induced (EIDM) groups. After 6 weeks, Johnson’s score was evaluated
to analyze the spermatogenesis ratio.
Results The Hsp70 and Hsp90 expression levels, testicular total antioxidant capacity (TAC), protein peroxidation ratio,
testicular DNA fragmentation ratio, and mRNA damage were investigated. The animals in EDM and EIDM groups (solely
and simultaneously) represented a significant (P<0.05) improvement in Johnson’s score, spermatogenesis, and TAC
ratios versus SDM animals. Moreover, the DM-induced DNA and mRNA damage and protein peroxidation ratio were
significantly (P<0.05) recovered in EDM and ISDM groups, which was more remarkable in the EIDM group. The EDM
and EIDM groups exhibited significant (P<0.05) increment in Hsp70 and Hsp90 expression levels versus the control
and SEDT1 animals. However, the EIDM group exhibited no significant changes compared to the control animals.
Conclusion The EX could ameliorate the EDT1-induced detrimental impact by up-regulating Hsp70 and Hsp90
expressions. Meanwhile, it exerts potentially more effective impact, when it is considered simultaneously with insulin
therapy.

Abstract
BACKGROUND AND PURPOSE The specific molecular mediators involved in dyslipidemia in older people are not yet clearly understood. The current study was, thus, an attempt to investigate whether moderate aerobic exercises and curcumin administration alleviates the abnormalities caused by aging in the rats' liver. EXPERIMENTAL APPROACH Thirty-two eight-year-old young rats were classified into five groups, namely, young control, aged control, aged-curcumin, aged-exercise, and aged-curcumin-exercise co-treatment. The rats in the exercise groups were trained on an animal treadmill for 60 min/day five times per week for eight weeks. FINDINGS/RESULTS The results revealed a significant increase in FAT/CD36, PTP1B, significantly decreased HNF4α genes expression, increase in LDL and cholesterol in the aged group compared to the young control. Compared to those in the young control group, no significant changes in HDL and TG amounts in the aged control were observed. Moreover, compared to the young control, the aged group showed liver histological changes such as fibrosis and mild or grade 1 steatohepatitis. Moderate aerobic exercise and curcumin alone or in combination completely masked this effect. CONCLUSION AND IMPLICATIONS The findings revealed dyslipidemia and liver steatosis related to aging might be partly associated with changes in hepatic transcriptional factors which can be mitigated via moderate aerobic exercise and curcumin.

Abstract
Despite other tissues, the effect of different exercise training protocols (ETPs) on the expression levels of metabolic substrates transmembrane transporters in the testicular tissue, remains completely unexplored. Thus, the effects of low, moderate and high-intensity ETPs on the SCs and germ cells potentials in GLUT-1, GLUT-3 and MCT-4 expression levels was investigated in this study. The animals were assigned into 4 groups, including sedentary control, low-intensity continuous (LICT), moderate-intensity (MICT) and high-intensity (HICT) ETPs-induced groups (n = 6/group). The GLUT-1, GLUT-3 and MCT-4 expressions, cytoplasmic carbohydrate storages of SCs and germ cells, the SCs survival and the spermatogenesis and spermiogenesis rates were assessed. The LICT and MICT did not significantly alter the protein expression levels of GLUT-3 and MCT-4 in the SCs and germ cells, while decreased the GLUT-1 protein content versus the sedentary control animals. In contrast, the HICT remarkably suppressed the GLUT-1 and MCT-4 in both SCs, and germ cells and diminished GLUT-3 in SCs and increased in the germ cells. No significant changes were revealed in the cytoplasmic carbohydrate storage in the LICT and MICT groups, while significantly diminished in the HICT group. The HICT group showed a failed spermatogenesis and spermiogenesis, which were not demonstrated in the sedentary control, LICT and MICT groups. In conclusion, the HICT, by reducing the GLUT-1, GLUT-3 and MCT-4 protein contents in the SCs and reducing the SCs survival, can suppress the glucose transmembrane transport and inhibit the lactate export from SCs, which in turn, ends with failed spermatogenesis and spermiogenesis.

Abstract
AIMS The spermatogenesis failure is reported as the main complication for diabetes and the moderate-intensity exercise (EX) is shown to ameliorate the diabetes-induced impairments both at spermatogenesis and sperm levels. Thus, the current study was done to investigate the possible effect of EX in the sole and simultaneous form with insulin on the network between Sertoli and spermatogonial stem cells (SSCs) by focusing on niche factor Glial cell-derived neurotrophic factor (GDNF). METHODS For this purpose, 30 mature male Wistar rats were divided into control and experimental type 1 diabetes (T1D)-induced groups. Then the T1D-induced animals were subdivided to sedentary T1D-induced (ST1D), EX + T1D, insulin (INS) + T1D and EX + INS + T1D groups. The general histological changes of testicles, mRNA and protein contents of GDNF and its special receptors gfrα1 and c-RET were evaluated and compared between groups. RESULTS EX in the sole and simultaneous form with INS significantly (p < 0.05) diminished the T1D-induced histological damages, amplified the GDNF expression, and enhanced the gfrα1 and c-RET mRNA and protein contents compared to ST1D group. CONCLUSION In conclusion, the EX in the sole form promotes spermatogenesis by up-regulating the GDNF signaling system. Moreover, EX remarkably amplifies the insulin-induced ameliorative effect on spermatogenesis.

Abstract
The aim of this study was to investigate the ameliorative effect of moderate-intensity exercise training in sole and simultaneous forms with insulin on experimental type 1 diabetes (T1D)-induced apoptosis. A total of 36 mature male Wistar rats were divided into six equally sized groups, including sedentary control (Con), moderate-intensity exercise training (E-sole), sedentary T1D-induced (D-sole), moderate-exercise-trained T1D-induced (DE), insulin-treated sedentary T1D-induced (DI) and exercise-trained, and insulin-treated T1D-induced (DEI) groups. The 6-week exercise training intervention was involved 30 min of moderate-intensity running on a treadmill once daily (5 days/week). Next, tubular differentiation (TDI) and spermiogenesis (SPI) indices were assessed. The Bcl-2, Bax and caspase-3 expressions were determined using RT-PCR, immunohistochemistry and western blot techniques. Finally, the TUNEL staining was used to analyze the apoptosis ratio. The moderate-intensity exercise training in the sole and when simultaneously considered with insulin (DEI) maintained testicular cellularity, up-regulated Bcl-2 expression, reduced Bax expression and ameliorated the diabetes-induced apoptosis. We failed to show remarkable alterations in caspase-3 mRNA and protein levels in the DE group versus D-sole animals. In conclusion, the moderate-intensity exercise training is able to potentially protect testicular cells from T1D-induced intrinsic apoptosis via up-regulating Bcl-2 and downregulating Bax expressions. Moreover, it amplifies the insulin-induced anti-apoptotic impacts.

Abstract
Misuse of anabolic androgenic steroids (AAS) increases prevalence of cardiovascular abnormalities in athletes, and the underlying molecular mechanism involved in those abnormalities continues to be investigated. The aim of this study was to investigate the effect of chronic nandrolone exposure on alpha and beta-myosin heavy chain (MHC) isoforms gene expression transition, blood pressure related parameters, calcium/calmodulin-dependent protein kinaseIIδ (CaMKIIδ), and monoamine oxidase (MAO) activities in rats' hearts. It was also planned to evaluate the effect of strenuous exercise on cardiac abnormalities induced by nandrolone. Thirty-two male wistar rats were assigned into four groups, namely control, nandrolone, nandrolone with strenuous exercise, and strenuous exercise groups. Nandrolone consumption significantly increased systolic, diastolic, pulse and dicrotic pressure, mean arterial pressure, as well as the amplitude of first peak (H1). Moreover, exercise combined with nandrolone completely masked this effect. The mRNA expression of β-MHC and the ratio of β -MHC/α -MHC showed a significant increase in the nandrolone and nandrolone with strenuous exercise groups compared to those in the control group. The values of heart tissue calcium/calmoldulin-dependent protein kinase IIδ (CaMKIIδ), and monoamine oxidase (MAO) in the nandrolone, nandrolone with strenuous exercise and exercise groups were significantly higher than those values in the control group. These findings indicate that nandrolone-induced heart and hemodynamic abnormalities may in part be associated with MHC isoform changes and Ca2+ homeostasis changes mediated by increased CaMKIIδ and MAO activities and that these effects can be provoked via strenuous exercise.

Abstract
Emami, A, Tofighi, A, Asri-Rezaei, S, and Bazargani-Gilani, B. Effect of short-term coenzyme Q10 supplementation and precooling on serum endogenous antioxidant enzymes of elite swimmers. J Strength Cond Res 32(5): 1431-1439, 2018-This study aimed to investigate the effect of the use of a 2-week precooling strategy and supplementation coenzyme Q10 (CoQ10) on superoxide dismutase (SOD), catalase (CAT), and serum glutathione peroxidase (GPx) in elite, adolescent swimmers during heavy and regular trainings and recording of freestyle swimming. Thirty-six healthy males (mean ± SD; age: 17.5 ± 1.1 years, body fat content: 14.55 ± 1.75%) were randomly selected and divided into 4 groups of CoQ10 (300 mg·d), precooling (immersion in the water at 18 ± 0.5° C), supplementation with precooling, and control, each with 9 participants. During an 18-session protocol in the morning and evening, participants attended speed and endurance trainings for 5 km every session. A 3-stage blood sampling was conducted before the first recording and before and after the second recording in 800, 200, and 50 m. Repeated measurement and the Bonferroni correction were used for the statistical analyses of the data (α = 0.05). According to the results, there was no significant difference between the mean serum level of SOD, CAT, and GPx in the groups at the first stage of blood sampling (p > 0.05). At the third stage, a significant difference was observed among all groups (p < 0.05). At the second stage, precooling and control groups show a significant increase compared with the supplementation and supplementation with precooling groups (p < 0.05). As an antioxidant essential for adenosine triphosphate synthesis, CoQ10 supplementation prevented adverse changes of antioxidant enzymes during heavy trainings and swimming recording and decreased the serum level, while precooling individually increased serum level of antioxidant enzymes by itself.

Abstract
BACKGROUND X-linked lymphoproliferative disease (XLP) is an often fatal inherited immunodeficiency disorder characterised by fulminant infectious mononucleosis, acquired haemophagocytic lymphohistiocytosis, dysgammaglobulinaemia and malignant lymphoma. Given the paucity of data on the genetic stratification of XLP gene mutations in paediatric patients diagnosed with B-cell lymphoma, we sought to determine the existence of such association in the present study. METHODS We studied 20 male subjects diagnosed with non-Hodgkin B-cell lymphoma. RESULTS Eleven patients had laboratory evidence of EBV infection by serology and quantitative PCR. The SH2D1A gene analysis was negative in all patients. CONCLUSIONS This is the first study to analyse the SH2D1A gene mutations in Iranian paediatric patients diagnosed with lymphoma. Although we could not demonstrate such an association in our cohort of patients, larger, multi-centre studies are required to extend and confirm our early findings.

Abstract
BACKGROUND Atherosclerotic cardiovascular disease is currently a cause of mortality in some parts of the world. The ATP-Binding Cassette Transporter (ABCA1) gene prepares instructions to produce the ATP-binding cassette transporter protein whose operation is for export of phospholipids and cholesterol, outside cells where they are limited to Apolipoprotein A1 (apoA1). Increased ABCA1 activity could inhibit atherosclerosis. OBJECTIVES In the present study, the effect of aerobic exercise was investigated on gene expression and biochemical parameters. PATIENTS AND METHODS The participants included 36 inactive women, which were randomly assigned to control (CON) and experimental (EX) groups. The EX group performed 12 weeks of aerobic exercise and the CON group remained inactive. Fasting blood samples were collected 24 hours before the first session and 48 hours after completion of the course. The ABCA1 and APOA1 gene expressions were measured using semi-quantitative-RT-PCR. Data were analyzed by the SPSS software (version 18). RESULTS A significant increase in blood ABCA1 (EX group P < 0.002, t = - 9.876) and Apo A-I (EX group P < 0.05, t = 2.76) gene expression was shown following the 12 weeks of training. Plasma high-density lipoprotein-cholesterol (HDL-C) concentration increased (P < 0.001, t = 4.90 respectively) while plasma low-density lipoprotein-cholesterol (LDL-C) concentration decreased (P < 0.001, t = 4.27) in the EX group compared with the CON group. CONCLUSIONS Aerobic exercises can increase ABCA1 and APO-A1 gene expression. Induction of these genes can effectively prevent cardiovascular disease.

Abstract
AbstractPoorly crystalline apatites (PCA) are characterized by a non-stoichiometric composition, a high specific surface area and the existence of labile, non-apatitic environments detected by spectroscopic techniques. These environments have been shown to belong mainly to an hydrated layer at the surface of the crystals and determine their surface and bulk reactivity. PCA can be easily synthesized in aqueous media and the amount of labile, non-apatitic environments can be modulated by using apatites at different maturation stage. PCA can adsorb many active proteins or drugs, Growth factors (FGF-2, for example), were strongly bound and remained mostly attached to the surface. Several mineral ions which have been shown to have a biological activity such as strontium, can also be trapped at the surface or into the lattice of poorly crystalline apatites. Due to their reactivity, PCA cannot be shaped easily into materials, however, they have the ability to agglomerate irreversibly into solid body at low temperature. These low temperature ceramics show a variable amount of pores (30 to 60 %) and pore size (5 to 25 nm) in which organic components can be trapped and are released only by the dissolution of the ceramic.

Abstract
The in vitro and in vivo properties of a novel, fully resorbable, apatitic calcium phosphate bone substitute (ABS) are described. The ABS was prepared from calcium phosphate precursors that were hydrated to form an injectable paste that hardens endothermically at 37 degrees C to form a poorly crystalline apatitic calcium phosphate (PCA). The PCA reaction product is stable in vivo as determined by FTIR and XRD analysis of rabbit intramuscular implants of ABS retrieved 4, 7, and 14 days postimplantation. Bone formation and resorption characteristics of the ABS material were characterized in a canine femoral slot defect model. Femoral slot defects in dogs were filled with either autologous bone implants or the ABS material. Sections of femoral bone defect site from animals sacrificed at 3, 4, 12, 26, and 52 weeks demonstrated that new bone formation proceeded similarly in both autograft and ABS filled slots. Defects receiving either material were filled with trabecular bone in the first 3 to 4 weeks after implantation; lamellar or cortical bone formation was well established by week 12. New bone formation in ABS filled defects followed a time course comparable to autologous bone graft filled defects. Histomorphometric evaluation of ABS resorption and new bone formation indicated that the ABS material was greater than 99% resorbed within 26 weeks; residual ABS occupied 0.36+/-0.36% (SEM, n = 4) of the original defect area at 26 weeks. Quantitatively and qualitatively, the autograft and ABS were associated with similar new bone growth and defect filling characteristics.

Abstract
alpha-BSM is a biomimetic endothermically setting apatitic calcium phosphate bone substitute material. Its injectability and ability to harden at body temperature in the presence of physiologic saline, and other buffering agents, makes it an attractive clinical bone substitute and delivery vehicle for therapeutic agents in orthopaedic and dental applications. In osseous tissue, alpha-BSM alone remodels into bone and promotes bone healing. alpha-BSM treatment has been shown in several animal models to be effective in promoting healing of surgically created critical size defects and restoring bone biomechanical strength to values equal to or greater than values achieved with autograft controls. In vitro studies with alpha-BSM containing gentamicin show that antibiotics can be incorporated stably into alpha-BSM and that the release kinetics can be controlled with the appropriate formulation and preparative procedures. Growth factors and enzymes also are compatible with the alpha-BSM setting reaction. The incorporation of recombinant human bone morphogenetic protein-2 with alpha-BSM was shown to be effective in stimulating bone formation and accelerating restoration of the differentiated phenotype in an osteotomy model. Clinical trial investigators in Europe currently are using alpha-BSM implantations for treatment of fractures and other indications.
