Abstract
The impact of circadian rhythms on cardiovascular function and disease development is well established, with numerous studies in genetically modified animals emphasizing the circadian molecular clock's significance in the pathogenesis and pathophysiology of myocardial ischemia and heart failure progression. However, translational preclinical studies targeting the heart's circadian biology are just now emerging and are leading to the development of a novel field of medicine termed circadian medicine. In this review, we explore circadian molecular mechanisms and novel therapies, including (1) intense light, (2) small molecules modulating the circadian mechanism, and (3) chronotherapies such as cardiovascular drugs and meal timings. These promise significant clinical translation in circadian medicine for cardiovascular disease. (4) Additionally, we address the differential functioning of the circadian mechanism in males versus females, emphasizing the consideration of biological sex, gender, and aging in circadian therapies for cardiovascular disease.

Abstract
Diabetes Mellitus (DM) can damage the function of metabolic tissues, including the liver. Liver macrophages are the first responders to tissue damage or exercise. We sought to determine whether eight weeks of interval training (HIIT & MIIT) protect against diabetes-induced modulation of hepatic CD86 and CD206 expression associated with the amelioration of insulin resistance and inflammation in rats. Thirty rats were divided into six groups, including a control group, MIIT, HIIT, DM, DM + MIIT, and DM + HIIT (n = 5 in each group). Diabetes was induced using a combination of a high-fat diet (HFD) and STZ. Wistar rats in the exercise groups were subjected to moderate and high-intensity interval training for eight weeks. After sample collection, liver tissue was removed and weighed. Serum levels of TNFα, IL-6, TGFβ, and IL-10 were measured by ELISA. Protein expression of the immune markers CD86 and CD206 in liver tissue was determined by immunohistochemical staining. Induction of diabetes increased glycemic indices, insulin resistance, and liver injury enzymes, especially in DM and DM + HIIT groups (p < 0.05). Moreover, diabetic groups showed an increase in liver CD86 protein expression, an increase in TNFα, IL-6, and TGFβ serum levels, and a decrease in liver CD206 and serum IL-10 (p < 0.05). Doing exercise while being diabetic, especially MIIT, significantly reversed the aforementioned factors and reduced insulin resistance (p < 0.05), except IL-10). We concluded that performing exercise training specially MIIT by decreasing CD86 and increasing CD206 in the liver, followed by decreasing pro-inflammatory factors (TNFα, IL-6) caused the regulation of liver enzymes and insulin resistance in diabetic rats. Therefore, it seems that exercise training by regulating macrophage markers CD86 and CD206 can reduce damage to the insulin-signaling pathway by reducing pro-inflammatory cytokines.

Abstract
In this study, we designed an engineered tissue and transplanted it to an animal model, trying to take an effective step toward meeting the needs of diabetic patients. Here, human endometrial cells were differentiated into PDX1-expressing cells using a small molecule of Y-27632 on polyacrylonitrile (PAN) electrospun scaffolds and transplanted into diabetic rats. PAN nanofibers were made by electrospinning. RT-PCR and immunocytochemical analysis were performed to express pancreatic precursor (PP) genes. The differentiated cells were then transplanted into the abdominal cavity of diabetic rats with Streptozotocin. In another group of rats, differentiated cells were injected through the tail. Blood glucose was measured 7, 14, and 28 days after transplantation, and rat weight was also measured. The results showed that the expression of PP markers including Sox-17, Ngn3, Pdx1, and NKx2.2 genes was significantly increased in differentiated cells compared to the control group. In diabetic rats receiving differentiated cells, both transplanted and injected, glucose concentration as well as body weight improved compared to the control group. Rats receiving transplants in the peritoneum had a lower blood glucose concentration than those in the cell receiving group by injection, and the cell receiving group in the form of injections was more effective in increasing the body weight of rats than in the other groups. According to the results of the study, the transplantation of PP from endometrium using PAN scaffolding at the site of peritoneum could be recommended for the treatment of diabetes, although further studies are needed to provide a complete cure.

Abstract
High temperatures can induce oxidative stress, impairment of spermatogenesis, and reduction of sperm quality and quantity concomitant with transient periods of partial or complete infertility in male mammals. Promising beneficial effects of betaine supplementation on the epididymal spermatozoa have been reported in experimental studies; however, its effects on testicular heat stress (HS)-induced impairment have yet to be determined. In the present study, betaine (Bet) was orally administrated (250 mg/kg day) during a 14-day period, before (Bet + HS group) or after (HS + Bet group) induction of testicular HS in 7-9 week-old male mice. HS was induced by testicular immersion in water at 42 °C in stress groups. Epididymal spermatozoa and testes were collected at days 14 and 28 after HS induction in order to analyze sperm characteristics, testicular oxidative status, and histological changes. Our studies showed that HS reduced testicular weight, the quality and quantity of epididymal spermatozoa, and impaired maturation of germinal cells. The levels of MDA, catalase, SOD, and GPX were increased in the testes of HS-induced mice (P < 0.01). Although betaine treatment before and after exposure to HS enhanced antioxidant defense (P < 0.05) and accelerated germinal epithelium regeneration, its effects on the characteristics of epididymal spermatozoa were scarce. On the other hand, in the absence of heat stress, quality and quantity of epididymal spermatozoa were improved following 14 days of betaine consumption. Our study revealed the beneficial effect of betaine on HS-induced complications of spermatogenesis, as well as its potency to improve epididymal spermatozoa in intact mice.

Abstract
Diabetes mellitus is one of the most common causes of neuropathy. Although antioxidant and antidiabetic effects of the aqueous extract of purslane (Portulaca oleracea) (AEOP) have been demonstrated before by other researchers, we did not find any study that assessed the psychobiological effects of AEOP in diabetes induced animals. Thirty ovariectomized (OVX) female Wistar rats were randomly divided into 3 groups of control, Dia and Dia+AEOP. The latter group was orally treated by 300 mg/kg of AEOP for 35 days. Dia and Dia+AEOP groups were made diabetic by IP injection of 60 mg/kg of streptozotocin (STZ). The psychobiological effects of AEOP were assessed by Morris water maze (MWM), elevated plus maze (EPM), forced swimming test (FST) and tail pinch stressor (TPS). AEOP significantly decreased hyperglycemia (p<0.001). Diabetes significantly decreased their spatial cognitive performance at the training trial as well as the total distance traveled at the probe trial in MWM (p<0.05). All the diabetes related deficits at training trials were improved by AEOP treatment (p<0.05). AEOP treatment not only improved the motor deficit of Dia group in EPM, but also showed anxiolytic effects compared to both control and Dia groups (p<0.05). In the FST, no differences were observed between any groups (p>0.05). Diabetes significantly increased their non-functional masticatory activity in TPS (p≤0.001) while it was improved in Dia+AEOP group. We showed that AEOP has significant anxiolytic effects and it can improve spatial cognitive performance, locomotor deficit and stress in diabetic OVX rats.

Abstract
Steadily increased use of silver nanoparticles (Ag-NPs), has increased the amount of its exposure to humans and animals. Current scarce knowledge about the influences of prenatal exposure to Ag-NPs on postnatal outcomes, motivated us to investigate whether being exposed to it during pregnancy has any effects on neurobehavioral development of the adult offspring. Thirty virgin female NMRI mice were mated and treated subcutaneously once every three days from gestation day 3 until delivery, by 0, 0.2 and 2 mg/kg of bodyweight (BW) of Ag-NPs. Behavioral functions of adult offspring including spatial memory, passive avoidance learning, stress, anxiety-like behaviors and locomotor activities were assessed by commonly used neurobehavioral paradigms and the results were compared according to treatment and sex. Prenatal exposure to Ag-NPs significantly impaired their cognitive behavior in the Morris water maze. Although no evidence was observed indicating more anxiety-like behaviors in the treated offspring in the elevated plus maze, the number of defecations and leanings in the open field assay and number of passages in the light-dark box were greater in groups prenatally treated by Ag-NPs. Most of the impairments were more apparent in the offspring which had been prenatally exposed to high doses of Ag-NPs, particularly female ones. The present study indicated that the exposure of pregnant animals to Ag-NPs may lead to various neurobehavioral disorders in their offspring. Thus, more attention should be paid to avoid exposure to Ag-NPs, especially from pregnant females.

Abstract
Carbon nanotubes with extraordinary properties may become a novel drug and gene delivery tool in nanomedicine; however, insufficient information is available regarding their biosafety. Therefore, this work was performed to study the effect of prenatal exposure of single-walled carbon nanotubes (SWCNTs) on reproductive and neurobehavioral endpoints in mice. Thirty pregnant female mice were assigned to three groups ( n = 10 for each group). The two treated groups were injected intraperitoneally (i.p.) with 1 or 10 mg/kg body weight (b.w.) of SWCNTs suspended in 1 ml of phosphate buffer saline (PBS) on gestational days 0 and 3. The control group was injected i.p. with an equal volume of PBS. The neurobehavioral ontogeny of pups was evaluated using a modified Fox battery. A decrease in litter size on postnatal day 2 was observed in the group treated with 10 mg/kg b.w. of SWCNTs whereas no significant differences between groups were observed in any other parameters. The behavioral development of pups did not show significant differences during growth except for the surface righting reflex, which showed significant delay compared to control in the group treated with 1 mg/kg b.w. SWCNTs. Moreover, exposed offspring (10 mg/kg b.w. SWCNTs) displayed enhanced anxiety in the elevated plus maze; however, other ethological analysis (Morris water maze and open field test) did not show behavioral changes in the experimental groups. In conclusion, the present results demonstrated small changes in offspring sensory and motor development following exposure to SWCNTs and support the idea that SWCNT risk assessment merits further investigation.

Abstract
PURPOSE The purpose of the present study was to investigate the effect of sesame oil on the reproductive parameters of diabetic male Wistar rats. MATERIALS AND METHODS The adult male rats in a split plot design were divided into normal (n=10), normal 5% (n=5; 5% sesame oil enriched diet), diabetic (Streptozocin induced diabetes; n=9), diabetic 5% (n=9; 5% sesame oil enriched diet), and diabetic 10% (n=9; 10% sesame oil enriched diet) groups. Diet supplementation continued for 56 days. RESULTS Sesame oil supplementation did not reduce the plasma glucose concentration of rats in the diabetic groups (p>0.05). The total spermatogonia, spermatocytes, Leydig cells/tubule, and the germ cell to Sertoli cell ratio were lower in the diabetic rats than the normal ones (p<0.05), and with the exception of spermatogonia counts, these values improved by the addition of sesame oil to the diet (p<0.05). The sperm progressive motility and viability were lower in the diabetic rats (p<0.05) and sesame oil supplementation did not improve them. Incorporation of sesame oil into the diet improved the plasma testosterone concentration of the diabetic rats in a dose-dependent manner (p<0.05). CONCLUSIONS In summary, sesame oil supplementation improved the reproductive parameters of diabetic rats at the levels of the testicular microstructure and function, but was not effective in protecting the epididymal sperm.

Abstract
OBJECTIVES Since diabetes mellitus is accompanied by cognitive impairment in diabetic patient and animal models and since lipids play important roles in neuronal membrane composition, structure and function; we intended to evaluate the effect of dietary butter oil on passive avoidance memory of streptoztosin (STZ)-induced diabetic rats in this study. MATERIALS AND METHODS THIRTY SIX ADULT MALE RATS WERE RANDOMLY ALLOCATED TO FOUR EQUAL GROUPS: normal (N) and diabetic control (D) groups with free access to regular rat diet; but the diet of normal butter oil (NB) and diabetic butter oil (DB) groups was supplemented with 10% butter oil. Diabetes in D and DB groups was induced by intravenous (i.v.) injection of 50 mg/kg.bw of STZ. Passive avoidance memory and cholesterol of brain and hippocampal tissues has been measured six weeks after diabetes confirmation. RESULTS Diabetes, especially in diabetic butter oil group decreased the abilities of learning and memory. The level of cholesterol in hippocampus was higher in NB (P< 0.05) and DB (P< 0.01) groups. CONCLUSION We suggest consumption of butter oil may worsen cognitive impairment of diabetic animal. This may be related to the higher elevation of cholesterol in the hippocampus of diabetic animals.
