Abstract
In order to evaluate the effects of ARG sources (arginine [ARG] and Guanidinoacetic acid [GAA]) and phenylalanine (PHE) supplementation on performance, susceptibility to ascites, intestinal morphology, and nutrient digestibility in the cold-stressed broilers fed a canola meal (CM)-based diet, a 2×2 factorial experiment with four treatments was conducted. The dietary treatments included CM-based diet + 2.57 g/kg ARG, CM-based diet + 2.57 g/kg ARG + 1.5 g/kg PHE, CM-based diet + 1.8 g/kg GAA and CM-based diet + 1.8 g/kg GAA + 1.5 g/kg PHE. The corn-CM diet without supplementation was used as a negative control (NC) group in the fifth treatment that excluded the factorial arrangement. The results showed that adding ARG to diets without PHE supplement increased (p < 0.05) feed intake. Also, birds fed diets containing ARG had higher (p < 0.05) body weight gain (BWG) compared to those fed GAA added diets. Supplementation of PHE improved (p < 0.05) the FCR compared to groups fed diets without added PHE. Further, ARG addition increased (p < 0.05) plasma nitric oxide (NO) concentration, carcass, breast and leg yields, duodenal, jejunal, and ileal villus height (VH) to crypt depth (CD, and dry matter digestibility, while decreasing (p < 0.05) ascites mortality and right ventricle (RV) to total ventricle (TV) ratio compared to GAA added groups. Supplementation of PHE also declined susceptibility to ascites by reducing (p < 0.01) RV to TV ratio while increasing (p < 0.05) plasma NO level. The digestibility of ether extract also increased (p < 0.05) in broilers fed GAA supplemented diets versus those fed ARG added diets. The findings suggested that ARG may improve BWG and lower ascites incidence in broilers fed a diet based on CM under cold stress because of its antihypertensive effects. Moreover, the findings of this study demonstrated the importance of including PHE formulation in ARG-deficient diets to attenuate the adverse effects of cold stress on broilers. It was also concluded that GAA could be efficaciously used in cold-stressed broilers fed an ARG-deficient diet.

Abstract
To estimate the repro-protective effect of royal jelly (RJ) on phenylhydrazine (PHZ)-induced anemia's detrimental effects, 24 mature mice were divided into control group (0.10 mL normal saline; intra-peritoneally), RJ group (100 mg/kg/day; orally), experimental anemia (EA) group that received only PHZ (6 mg/100 g/48 h; intra-peritoneally), and RJ + EA (according to the previous prescription) group. After 35 days, testicular histoarchitecture, RNA damage in germinal cells, sperm characteristics, testicular total anti-oxidant capacity and malondialdehyde as well as serum testosterone levels, pre-implantation embryo development and cyclin D1 and c-myc mRNA levels at two-cell, morula and blastocyst stages were analyzed. Spermatogenesis indices were ameliorated following RJ co-administration. Moreover, RJ co-treatment reduced germinal cells RNA damage, improved sperm characteristics, boosted pre-implantation embryo development and restored androgenesis, and oxidant/anti-oxidant status. Co-administration of RJ also decreased mRNA levels of cyclin D1 and up-regulated those of c-myc in two-cell embryos, morulas and blastocysts. The findings suggest that RJ can play a repro-protective role in PHZ-induced anemia in mice through anti-oxidant defense system reinforcement and androgenesis restoration as well as cyclin D1 and c-myc expressions regulation.

Abstract
COVID-19 has heightened human suffering, undermined the economy, turned the lives of billions of people around the globe upside down, and significantly affected the health, economic, environmental and social domains. This study aims to provide a comprehensive analysis of the impact of the COVID-19 outbreak on the ecological domain, the energy sector, society and the economy and investigate the global preventive measures taken to reduce the transmission of COVID-19. This analysis unpacks the key responses to COVID-19, the efficacy of current initiatives, and summarises the lessons learnt as an update on the information available to authorities, business and industry. This review found that a 72-hour delay in the collection and disposal of waste from infected households and quarantine facilities is crucial to controlling the spread of the virus. Broad sector by sector plans for socio-economic growth as well as a robust entrepreneurship-friendly economy is needed for the business to be sustainable at the peak of the pandemic. The socio-economic crisis has reshaped investment in energy and affected the energy sector significantly with most investment activity facing disruption due to mobility restrictions. Delays in energy projects are expected to create uncertainty in the years ahead. This report will benefit governments, leaders, energy firms and customers in addressing a pandemic-like situation in the future.

Abstract
The current study was conducted to analyze the dose-dependent effects of liraglutide against the diabetes-induced detrimental impact on sperm parameters and fertilization potential. For this purpose, 42 adult male mice were randomly divided into control (with no intervention) and experimental groups. Next, the experimental group was subdivided into diabetic, 1.20 mg kg-1 liraglutide-received diabetic, 1.80 mg kg-1 liraglutide-received diabetic, 1.20 mg kg-1 liraglutide-received non-diabetic and 1.80 mg kg-1 liraglutide-received non-diabetic groups. All chemicals were administrated subcutaneously. Following 42 days, the animals were euthanized, and sperm samples were collected. The sperm count, motility, viability, DNA integrity, and maturity were analyzed and compared between groups. Moreover, the sperm fertilization potential was investigated by in vitro fertilization (IVF). For this purpose, the preimplantation embryo development at 2-cell, 4-cell, morula, and blastocyst stages was investigated and compared. Observations revealed that diabetes significantly diminished sperm count, motility, viability, chromatin condensation, and DNA integrity percentages versus a control group. On the other hand, 1.20 mg kg-1 and 1.80 mg kg-1 of liraglutide did not improve sperm motility and viability, while ameliorated sperm count and chromatin condensation and DNA integrity in diabetic animals. The diabetic animals represented diminished preimplantation embryo development, which was not altered in liraglutide-received groups. In conclusion, at least in administrated doses, liraglutide could not improve the sperm viability and motility and, via this mechanism, could not induce an appropriate/beneficial effect on IVF outcome.

Abstract
Testicular heat stress (HS) can lead to testicular tissue destruction and spermatogenesis disturbances. Royal Jelly (RJ) has been introduced as a potent antioxidant. We investigated the effects of RJ on testicular tissue, oxidative stress and sperm apoptosis in HS-exposed rats. Compared to HS-exposed groups, RJ co-treatment could improve testosterone reduction and histopathological damages. The RJ co-administration decreased MDA level in testicular tissue, while TAC and CAT levels were remarkably increased compared to HS-exposed groups. Moreover, significant higher expression level of Bcl-2 and lower expression levels of P53 and Caspase-3 were seen following RJ co-administration compared to HS-exposed groups. Our data suggest that RJ can effectively ameliorate experimental HS-induced testiculopathies in rats through testicular antioxidant defense system restoration and germ cells apoptosis regulation.

Abstract
Ethephon (C2H6ClO3P; ETP), an organophosphorus pesticide regulating plant growth, is widely used for early ripening of fruits and vegetables in agriculture. The aim of this study was to investigate the effects of ETP on histomorphometrical and biochemical parameters in mouse testicular tissue. In this study, 90 adult male mice were randomly divided into six equal groups (n = 15). The ETP was administered orally at different doses (120, 240 and 480 mg kg-1) daily for 35 days. Untreated control, sham (received only normal saline) and neostigmine bromide-treated (positive control; 0.10 mg kg-1 orally; once per week) groups were also considered. Following 35 days, animals were euthanized and testicle and serum samples were taken. Accordingly, blood and serum acetylcholinesterase (AChE), catalase, total antioxidant capacity (TAC) and malondialdehyde (MDA) levels as well as histomorphometrical changes of testicles were investigated. The ETP-administered animals represented a significant reduction in AChE, TAC and catalase levels and remarkable increment in MDA content. A marked reduction was also seen in the germinal epithelium height, connective tissue thickness, seminiferous tubules diameter and Leydig cell number as well as spermiogenesis and Sertoli cell indices in ETP-treated mice compared to control ones. Similar findings were found in neostigmine bromide-treated animals. In conclusion, the ETP significantly affects the serum and blood anti-oxidant statuses and results in severe histological damages both at germ and somatic cell levels, suggesting its hematotoxic and reprotoxic characteristic.

Abstract
Background Polycystic ovary syndrome (PCOS) is an oxidative state resulting in ovarian dysfunction. Licorice is one of the natural antioxidants used for the treatment of infertility. Objective To evaluate the effect of licorice extract on ovarian morphology, oocyte maturation, and embryo development in PCOS-induced mice. Materials and Methods thirty-two female NMIR mice were divided into four groups (n = 8/each): control group receiving no treatment (group I); PCOS group injected with estradiol valerate once daily for 21 days (group II); and experimental groups receiving either 100 mg/kg (group III) or 150 mg/kg (group IV) licorice by gavage along with estradiol valerate once daily for 3 wk. Serum levels of the testosterone and estrogen were measured using ELISA kit. Histological study of ovaries was evaluated, and oocyte maturation, fertilization rate, and embryo development were determined after in vitro maturation. Results Experimental groups (III, IV) had significantly higher testosterone and estradiol levels compared to the PCOS group (p ≤ 0.001). A significant increase in the number of healthy follicles (primary, preantral follicles) (p = 0.001), corpus luteum (p = 0.001) with significant decrease in the number of atretic follicles (primary, preantral, cystic follicles) (p ≤ 0.001) was seen in the experimental groups. Increase in the fertilization rate (p ≤ 0.001) and blastocyst stage embryos (p = 0.02, p = 0.004) were observed in the experimental groups. Conclusion It appears that the two doses (100 mg and 150 mg) of licorice could decrease ovarian cyst and improve the fertilization rate of oocyte and embryo development in PCOS mice. However, there was no statistically significant difference between the two experimental groups.

Abstract
Polyvinyl chloride (PVC) has toxic effects through the induction of oxidative stress in the body and testicles. Vitamin E (Vit E) is a dietary compound that functions as an antioxidant scavenging toxic free radicals. The present study aimed to probe the protective effect of Vit E against PVC-induced reprotoxicity in male rats. In this experimental study, 24 male rats were randomly divided into four groups (n=6) including control, Vit E (150 mg kg-1 per day; orally), PVC (1000 mg kg-1 per day; orally) and PVC + Vit E. After 40 days, rats were euthanized and epididymal sperms characteristics, embryo development and malondialdehyde (MDA) and testosterone levels were examined. The PVC decreased sperm count, motility and viability as well as testosterone level and increased sperms with damaged chromatin in comparison with controls. Also, the percentages of fertilization, two-cell embryos and blastocysts as well as MDA levels were decreased in PVC-treated rats. However, Vit E improved PVC-induced alterations in aforesaid parameters. The results indicated that PVC can reduce fertility potential in male rats probably through androgen and sperm quality and quantity reductions, while Vit E can exert protective effects in PVC-related reproductive toxicities.

Abstract
It is well documented that aging has negative effects on fertility. With increasing age, the activity of antioxidant enzymes are reduced and because of roosters sperm composition, a high proportion of polyunsaturated fatty acids (PUFAs), the probability of sperm damage increases. The objective of the present study was to compare the effects of nano-selenium and sodium selenite on fertility in aged male broiler breeder chickens. Thirty-five male broiler breeders (Cobb 500)® at 50 weeks of age were randomly divided into five equal groups: The control group was fed on a commercial diet, group T1 was fed on a commercial diet supplemented with sodium selenite (0.30 mg kg-1 feed), group T2, T3 and T4 were fed on a commercial diet supplemented with nano-selenium (0.15, 0.30 and 0.60 mg kg-1 feed, respectively). Sperm characteristics (sperm count, motility, viability, and maturity) as well as testicular histomorphometric features [tubule differentiation (TDI), spermiation (SPI), Sertoli cell (SCI) and meiotic (MI) indices] were assessed. The results showed that sperm characteristics were gradually decreased with age in the control group, however, it increased in group T3. Also, TDI, SPI, SCI, and MI in group T3 were higher than those of other groups. Our findings revealed that dietary supplementations with nano-selenium boosted fertility in aged male broiler breeders and the best results were obtained when the roosters received 0.30 mg kg-1 nano-selenium. Supplementation of nano-selenium in aged broiler breeder males might be effective to maintain flock fertility and/or increase the flock fertility.

Abstract
In order to conduct this study, eight adult turkey heads were obtained. Pituitary glands were harvested following cranial bones removal and examined morphologically and anatomically as well as topographically. Then, tissue sections were prepared and stained using Hematoxylin and Eosin, Alcian blue, orange G and periodic acid-Schiff staining techniques. The results showed that turkey pituitary gland as a pea-sized structure is located in the ventral part of the cerebrum and composed of adenohypophysis and neurohypophysis parts. Moreover, histological analyses revealed that sinusoids are well-developed at the distal part of the adenohypophysis and irregular masses of endocrine cells exist among them. Distributions of basophilic cells in the distal part of adenohypophysis were significantly higher than those of other endocrine cells, while the acidophilic cells had the lowest distribution. Lower and higher numbers of chromophobe cells were also found compared to those of basophilic and acidophilic cells, respectively. These findings were mostly similar to the other birds' pituitary gland anatomical and histological features, but there were also differences in cellular elements distributions along with infundibular cavity topography.

Abstract
This study describes the effects of royal jelly (RJ) on testicular injury induced by nicotine (NIC) in mice. Thirty-six male BALB/c mice were randomly divided into six groups (n = 6). Group 1 received normal saline, group 2 received 100 mg/kgBW/day RJ, groups 3 and 4 received NIC at doses of 0.50 and 1.00 mg/kgBW/day, respectively, and groups 5 and 6 received NIC at doses of 0.50 and 1.00 mg/kg BW/day, respectively, plus RJ. Following 35 days, the serum level of testosterone, histopathological changes, germ cell apoptosis, proliferating cell nuclear antigen (PCNA), malondialdehyde (MDA) content, and antioxidant indexes including total antioxidant capacity (TAC) and catalase (CAT) activity were determined. In addition, the mitochondria-dependent apoptosis was investigated by assessing the Bcl-2, p53, and Caspase-3 mRNA levels expression by reverse transcription-PCR (RT-PCR). Compared to NIC receiving groups, the concomitant administration of RJ could protect the testosterone reduction and histological damages. After RJ treatment, the level of tissue MDA content decreased, while tissue TAC and CAT levels were remarkably increased compared to NIC-exposed groups. Remarkable higher TUNEL-positive germ cells and low PCNA index were observed in NIC receiving groups. Besides, the expression level of Bcl-2 was significantly higher and the p53 and Caspase-3 levels were significantly lower in the RJ co-administration groups than NIC-only receiving groups. Our results confirmed that RJ effectively protects the testis against NIC evoked damages by antioxidant and anti-apoptotic effects involving the up regulation of the antioxidant status, mitochondria-dependent apoptosis pathway prevention, and the proliferating activity improvement.

Abstract
Royal jelly (RJ) as an antioxidant has been shown to have attenuated oxidative stress damages in reproductive organs. The objective was carried out the effects of RJ on sperm characteristics, sperm malondialdehyde (MDA) concentration and in vitro fertilisation (IVF) outcome in heat stress (HS) exposed male rats. Forty-eight male rats were randomly divided into eight groups; group 1 received normal saline, group 2 received RJ (100 mg kg-1 day-1 ; PO), groups 3, 4 and 5 were heat-stressed (43, 39 and 37°C for 20 min per day respectively) and groups 6, 7 and 8 were heat-stressed along with RJ (43, 39 and 37°C for 20 min per day, respectively, plus RJ at a dose of 100 mg kg-1 day-1 ; PO). The HS was induced through immersion of experimental rat scrotums in a water bath. After 48 days, the HS induced remarkable diminish in sperm motility, viability and fertilising potential along with reduced blastulation rate and enhanced sperm chromatin abnormality, MDA levels and DNA damage. Nevertheless, RJ co-administration improved sperm characteristics and early embryo development as well as sperm lipid peroxidation level. Our data suggest that RJ can effectively ameliorate the experimental HS-induced infertility in rats through MDA concentration restoration and sperm characteristics and pre-implantation embryo development improvement.

Abstract
The presence of cyclopiazonic acid (CPA) as a mycotoxin has been reported in feed and foodstuffs. The aim of this investigation was to determine the effects of CPA on reproductive functions of male mice. In this experiment, 40 mature male mice were randomly assigned into five groups (n=8): control, control-sham, CPA (0.03 mg/kg, body weight (BW)), CPA (0.06 mg/kg, BW) and CPA (0.12 mg/kg, BW). Following 28 days exposure to CPA, sperm quality parameters, in vitro fertilisation (IVF) capacity of sperms, serum testosterone level, Leydig cells number and serum total antioxidant capacity (TAC) were analysed. The results revealed a significant (P<0.05) reduction in sperm count, sperm viability, sperm motility, chromatin quality of sperm, sperms with intact DNA, IVF rate, testosterone level, Leydig cell distribution and TAC in comparison to the control group. The most prominent detrimental effects of CPA were found at the highest given dose level. Our results suggest that CPA at higher dose levels exerts detrimental effects on the male reproductive system. Moreover, these descriptive warrant further investigations into the specific mechanisms of action and the effects of CPA on spermatogenesis.

Abstract
This study evaluated the possible protective effect of royal jelly (RJ) on sperm parameters and sperm malondialdehyde (MDA) concentration and in vitro fertilizing potential in nicotine (NIC) exposed male mice. Thrtiy-six male BALB/c mice were randomly divided into six groups (n = 6). Group 1 received normal saline, group 2 received 100 mg kg-1 per day RJ, groups 3 and 4 received NIC at doses of 0.50 and 1.00 mg kg-1 per day, respectively and groups 5 and 6 received NIC at doses of 0.50 and 1.00 mg kg-1 per day, respectively plus RJ. Caudal epididymal sperm characteristics, lipid peroxidation and in vitro fertilizing capacity and embryo development were evaluated after 35 days. The NIC treatment caused a significant decrease in sperm motility and viability and fertilization rate along with poor blastocyst formation and increased sperm DNA damage and MDA levels. Moreover, the incidences of chromatin abnormality in spermatozoa were significantly higher in NIC-exposed mice than those of control. Nevertheless, RJ treatment improved sperm parameters and in vitro fertilization outcome as well as sperm lipid peroxidation level. Data from the current study suggest that RJ has a potential repro-protective action against NIC-induced sperm abnormalities and embryotoxicity in mice.

Abstract
OBJECTIVES The current study was conducted to examine the possible protective and retentive effects of one-week intra-peritoneal (IP) administration of selenium nanoparticles (Se-NPs), compared to its bulk counterpart, selenite sodium (Ss), after one complete cycle of spermatogenesis in mature male mice. MATERIALS AND METHODS Thirty adult male mice were divided into 3 groups. Control group was administrated phosphate-buffered saline (IP) and the other groups received Ss (0.50 mg kg-1) and Se-NPs (0.50 mg kg-1) for seven successive days. Then, the animals were monitored for 28 days and finally sacrificed and tissue and blood samples were taken. Histopathological features, sperm quality, in vitro fertilization (IVF) capability and selenium (Se) content in testicular tissue were analyzed. Antioxidant enzyme activities including catalase, glutathione peroxidase, and superoxide dismutase as well as total antioxidant capacity and malondialdehyde levels were assessed in blood and the tissue samples. RESULTS Remarkable differences were found in sperm characteristics, histopathological features and oxidative stress biomarkers between control and treatment groups. Moreover, IVF evaluation and tissue Se concentration examination weren't similar for Se-NPs and Ss. CONCLUSION Conclusively, Se-treated groups had more antioxidant capacity than the control group, but sperm quality and histopathological features revealed that Se-NPs might possess more antioxidative and retentive potential compared to Ss in one spermatogenesis cycle.

Abstract
Foeniculum vulgare (FVE; fennel) is an aromatic plant belonging to Umbelliferae family, which is widely used in traditional societies because of its different pharmaceutical properties. To uncover the fennel-derived essential oil (FVEO)-induced effects on male reproductive potential, 24 mature male albino mice were divided into, control, 0.37, 0.75, and 1.5 mg kg-1 FVEO-received groups. Following 35 days, the animals were euthanized and the testicular tissue and sperm samples were collected. The histological alterations, tubular differentiation (TDI), spermiogenesis (SPI) indices, apoptosis ratio, and RNA damage of germinal cells were analyzed. Moreover, the sperm count, motility, viability, chromatin condensation, and DNA fragmentation were assessed. Finally, the pre-implantation embryo development including; the percentage of zygote, 2-cell embryos and blastocysts were assessed. Observations showed that the FVEO, dose dependently, increased histological damages, resulted in germ cells dissociation, depletion, nuclear shrinkage and significantly (P < .05) decreased tubular differentiation and spermiogenesis ratios. Moreover, the FVEO-received animals (more significantly in 1.5 mg kg-1 -received group) exhibited decreased sperm count, viability, and motility and represented enhanced percentage of sperms with decondensed chromatin and DNA fragmentation. Finally, the animals in FVEO-received group showed diminished zygote formation and represented decreased pre-implantation embryo development compared to control animals. In conclusion, our data showed that, FVEO albeit at higher doses, is able to adversely affect cellular DNA and RNA contents, which in turn is able to negatively affect the sperm count and morphology. All these impairments are able to negatively affect the fertilization potential as well as pre-implantation embryo development.

Abstract
The aim of this study was to uncover the protective effect of berberine (BBR), an antioxidant chemical, on experimental varicocele (VCL)-induced adverse effects on cell cycle machinery during early germ cells mitosis. To follow-up this study, 30 mature male Wistar rats were divided into control-sham, nontreated VCL, 50 mg kg-1 and 100 mg kg-1 BBR-treated VCL groups. Following 60 days, histological alterations were analysed by haematoxylin and eosin (H and E) staining, and expressions of cyclin-D1, cyclin-dependent kinase-4 (cdk4) and p21 were investigated by immunohistochemical (IHC) staining technique. Finally, DNA ladder test was carried out to examine the testicular DNA fragmentation. Administration of BBR remarkably diminished the percentage of seminiferous tubules with deformed shape, depleted germ cells and germ cells dissociation compared to VCL-sole group. The IHC observations showed that BBR significantly (p < .05) reduced VCL-induced p21 expression increase and up-regulated cyclin-D1 and cdk4 expressions. Moreover, BBR decreased VCL-induced DNA fragmentation. In conclusion, BBR can promote cell cycle through cellular DNA content protection, p21 expression down-regulation and maintaining cyclin-D1 and cdk4 expressions. Thus, BBR could be considered as a novel protective biochemical agent against experimental VCL-induced derangements. However, more studies are needed to uncover BBR-induced effects on cells cycle process and germ cells development.

Abstract
Current study was done to assess possible anti-proliferative effect of nanomicelle curcumin (NMCM) against germ cells in testicular tissue. For this purpose, 24 mature male Wistar rats were divided into control and test groups. The animals in test groups received 7.5mg/kg, 15mg/kg and 30mg/kg of NMC (NO=6 rats in each group). Following 48days, the expression of Bcl-2, Bax, caspase-3, P53 and proliferating cell nuclear antigen (PCNA) were evaluated by using reverse transcription-PCR and immunohistochemistry. Histological changes, tubular differentiation index (TDI), tissue cellularity and serum level of testosterone were analyzed. Finally, the DNA laddering test was used to assess the DNA fragmentation as hallmark for apoptosis. The NMCM significantly (P<0.05) diminished the Bcl-2, p53 and PCNA and enhanced the Bax and caspase-3 mRNA levels. The NMCM significantly (P<0.05) elevated the percentage of Bax and caspase-3-positive tubules and remarkably reduced the percentage of tubules with positive reaction for Bcl-2, p53 and PCNA. The NCMN-received animals exhibited remarkable (P<0.05) reduction in cell population, TDI ratio and serum level of testosterone. Severe DNA fragmentation was observed in 30mg/kg NMCM-received group. In conclusion, the NMCM by reducing the testicular endocrine status, down-regulating Bcl-2 expression and by enhancing the Bax and caspase-3 expression initiates the intrinsic apoptosis pathway. On the other hand, inhibited expression of p53 and PCNA (at dose level of 30mg/kg) suppresses the p53 and PCNA-related hemostasis/preservative reactions. All these alterations adversely affect the spermatogenesis.

Abstract
Bisphenol-S (BPS) is a new bisphenol-A substitute widely used in many plastic products. Bisphenol-A as a main member of bisphenol family has been known as an endocrine system disrupter chemical compound. Like other members of bisphenol family, there is public health concern about the toxic effects of BPS on reproductive system, thus, we examined BPS effects on in vitro fertilization (IVF) potential and oxidative stress status in a murine model. Adult female mice (n = 70) were randomly divided into control and BPS-treated groups. Bisphenol-S was administered at doses of 0, 1, 5, 10, 50 and 100 µg kg-1 body weight per day intraperitoneally for 21 consecutive days. Twenty-Four hr after the last treatment, five mice in each group were super-ovulated and the oocytes were harvested for IVF. All ovaries were collected and used for biochemical factors analyses. Bisphenol-S exposure at doses more than 10 µg kg-1 induced developmental arrest of pre-implantation embryos. Further, lipid peroxidation measurement in ovaries indicated that all doses of BPS cause oxidative stress in female mice. In conclusion, BPS administration even in low doses can result in female reproductive toxicities and oxidative stress in mice.

Abstract
The middle ear ossicles are important due to transmission of sound to the inner ear leading to sound understanding. The aim of present study was to determine the anatomical and morphometrical aspects of middle ear ossicles in Makouei sheep fetuses. For this experimental study, eight sheep fetuses at the age of 2 to 3 months were provided from public slaughterhouse; their middle ear ossicles were removed from tympanic cavity subsequently and assessed anatomically using stereomicroscope. For statistical analysis, one-way ANOVA and Tukey's post-hoc test were used. The results showed that rostral process of malleus doesn't exist, but an osseous lamina extending to the tympanic bulla and tympanic ring is located in this place. Moreover, lenticular bone and muscular process of stapes weren't found. These findings were similar to the other animal's ossicles anatomical features, but there were also some differences that can be useful for study of these ossicles developmental evolution.

Abstract
Chlorpyrifos (CPF) is a broad spectrum organophosphate pesticide used for agricultural health purposes. Its principal mechanism of toxicity is the inhibition of acetylcholinesterase. The purpose of present study was to investigate the effects of CPF on testicular tissue and sperm parameters in male rats. Thirty-two healthy male rats were divided into two groups: a CPF-exposed group and a control-sham group. Control-sham group received corn oil (0.20 mL per day). The CPF was administered orally to male rats at 37 mg kg-1 BW for 45 days to evaluate the reproductive toxicity. In all rats, sampling for histological and sperm analyses was performed on days 5, 15, 30 and 45. The CPF caused a significant (p < 0.05) decrease in sperm count, viability and motility and increased immature sperms and DNA damage in sperm cells. Light microscopic analyses revealed increased arrested spermatogenesis, negative tubular differentiation and repopulation indexes and decreased Leydig cells number. These findings indicate that CPF has adverse effects on sperm cells and reproductive system of male rats.

Abstract
Background Methotrexate (MTX), as an anti-folate agent, is widely used in the
treatment of rheumatic disorders and malignant tumors, however it damages reproductive sys-
tem in mice. The aim of this research was to study the effects of ethyl pyruvate (EP) on embryo
development and oxidative stress changes in the testis of mice treated with MTX.
Materials and Methods In this experimental study, thirty-two adult male Naval
Medical Research Institute mice, with average weight of 26 ± 2 g, were divided into
four groups. The first group (control) received distilled water (0.1 ml/mice/day), while
the second group was intraperitoneally (IP) treated with 20 mg/kg MTX once per
week. The third group was IP treated with 40 mg/kg/day EP, and the fourth group was
IP treated with both 20 mg/kg MTX and 40 mg/kg/day EP for 30 days. At the end of
treatment fertilization rate and embryonic development were evaluated. Differences
between these groups were assessed by ANOVA using the SPSS software package for
Windows with a Tukey-Kramer multiple post-hoc comparison test. Results MTX treatment caused significant (P<0.05) increase in malondialdehyde
(MDA) and reduced catalase (CAT), as well as leading to in vitro fertilization (IVF) and
embryonic development. The improved effects of EP on the IVF were determined by the
reduced level of MDA (index of oxidative stress) and significant increased level of CAT
(a key antioxidant). We observed significant increase in fertilization rate and embryonic
development in the treated group with both MTX and EP. Conclusion It is suggested that EP can be useful in ameliorating testicular
damages and embryotoxicity induced by MTX. These effects could be attributed to its
antioxidant properties.

Abstract
The present experiment was conducted to evaluate the effects of organic acids and phytase enzyme supplementation on performance and intestinal histomorphology of broilers. The experiment was done in a factorial arrangement 2 × 2 × 2 based on completely randomized design with eight treatments, five replicates with 12 chicks in each until 42 days of age. Diets included natural vinegar (0 and 2%), citric acid (CA; 0.00 and 1.00%) and phytase enzyme (PHY; 0.00 and 500 FTU phytase per kg of feed). One bird from each treatment replicate was randomly selected and slaughtered to evaluate the small intestinal morphology on 42 days of age. Analysis of results showed that vinegar increased feed consumption and body weight gain in total experimental period (p ˂ 0.05), while CA significantly decreased feed consumption on 0-14 days of age (p ˂ 0.05). No effect was observed on performance in interaction of organic acids together and with PHY group (p > 0.05). In duodenum CA increased the villus height and width (p ˂ 0.05) and PHY enzyme increased villus width (p ˂ 0.05) and decreased crypt depth (p ˂ 0.05). On the other hand, CA along with PHY significantly decreased crypt depth (p ˂ 0.05). In jejunum PHY alone and in combination with vinegar increased the goblet cells numbers (p ˂ 0.05), whereas vinegar significantly increased the goblet cells numbers in ileum (p ˂ 0.05). The muscular thickness in duodenum, jejunum, and ileum was not affected among different treatment groups. The results showed that supplementation of organic acids and phytase together in this experiment, with no negative effects on each other, improved their effects on some parameters.

Abstract
Background The effects of cyclosporine (Cs), a fungal cyclic polypeptide with potent
immunosuppressive activity, on fertility have assumed greater significance with the increasing numbers of transplantations being performed all over the world. Current study
was undertaken to investigate the potential of Satureja khuzestanica Essential Oil (SEO)
as an antioxidant to mitigate Cs-induced reprotoxicity. Materials and Methods In this experimental study (April-July 2012), thirty-two
adult male Wistar rats were randomly divided into 4 groups of 8 animals each. Two
groups of rats were administered Cs [40 mg/kg/day, per oral (p.o.)] for 45 days. One
of these groups received SEO (225 mg/kg/day, p.o.) four hours after Cs administration. A vehicle-treated control group and a SEO control group were also included.
Epididymal sperm characteristics, in vitro fertilizing capacity as well as embryo development were evaluated. For statistical analysis, one-way ANOVA and Tukey’s
post-hoc test were used, and the value of P<0.05 was considered as the criterion for
statistical significance. Results Sperm count and viability along with fertilization and blastocyst development
rates were significantly decreased by Cs treatment. Moreover, Cs-treated group showed
significant increases in DNA damage, protamine deficiency of the sperm cells and proportion of spermatozoa with cytoplasmic droplet. Notably, aforementioned parameters
were improved to near normal level by SEO co-administration. Conclusion These results suggest that SEO has a protective action against Cs-induced
reprotoxicity in a rat model.

Abstract
OBJECTIVE To determine bilateral effects of unilateral iatrogenic vas deferens trauma (UIT) on epididymal sperm characteristics and in vitro fertilizing capacity in an experimental mouse model. METHODS Experiments were performed on three equal groups each comprising six adult male mice. Following anaesthesia, UIT was induced by clamping left vas deferens with a mosquito clamp in fully locked fashion for 2 minutes in UIT group. Control-sham mice only had exposure of the left vas deferens through a groin incision. Control animals only received ceftriaxone (100 mg/kg) intraperitoneally at the day of experimental UIT induction. Ipsilateral and contralateral epididymal sperm characteristics and in vitro fertilizing capacity were evaluated after 35 days. RESULTS UIT significantly decreased sperm concentration, motility and viability as well as fertilization, two-cell embryos, blastocysts and hatched blastocysts rates. Moreover, incidence of DNA damage and abnormality in spermatozoa was significantly higher in UIT group. CONCLUSION The findings suggest that a non-recognized iatrogenic vas deferens trauma may have detrimental effects on spermatozoa leading to infertility.

Abstract
Biodiesel is a green (clean), renewable energy source and is an alternative for diesel fuel. Biodiesel can be produced from vegetable oil, animal fat and waste cooking oil or fat. Fats and oils react with alcohol to produce methyl ester, which is generally known as biodiesel. Because vegetable oil and animal fat wastes are cheaper, the tendency to produce biodiesel from these materials is increasing. In this research, the effect of some parameters such as the alcohol-to-oil molar ratio (4:1, 6:1, 8:1), the catalyst concentration (0.75%, 1% and 1.25% w/w) and the time for the transesterification reaction using ultrasonication on the rate of the fatty acids-to-methyl ester (biodiesel) conversion percentage have been studied (3, 6 and 9 min). In biodiesel production from chicken fat, when increasing the catalyst concentration up to 1%, the oil-to-biodiesel conversion percentage was first increased and then decreased. Upon increasing the molar ratio from 4:1 to 6:1 and then to 8:1, the oil-to-biodiesel conversion percentage increased by 21.9% and then 22.8%, respectively. The optimal point is determined by response surface methodology (RSM) and genetic algorithms (GAs). The biodiesel production from chicken fat by ultrasonic waves with a 1% w/w catalyst percentage, 7:1 alcohol-to-oil molar ratio and 9 min reaction time was equal to 94.8%. For biodiesel that was produced by ultrasonic waves under a similar conversion percentage condition compared to the conventional method, the reaction time was decreased by approximately 87.5%. The time reduction for the ultrasonic method compared to the conventional method makes the ultrasonic method superior.

Abstract
Background Diabetes mellitus has a variety of structural and functional effects on the
male reproductive system. Diabetes results in reduced sperm parameters and libido. The
present study aims to investigate the effects of royal jelly (RJ) on reproductive parameters of testosterone and malondialdehyde (MDA) production in diabetic rats. Materials and Methods This experimental study was conducted on adult male Wistar
rats. The animals were divided into four groups (n=8 per group): control, RJ, diabetic and
diabetic treated with RJ. Diabetes was induced by intraperitoneal injection of 60 mg/kg
body weight (BW) of streptozotocin (STZ). RJ, at a dose of 100 mg/kg BW was given
by gavage. The duration of treatment was six weeks. After the treatment period the rats
were sacrificed. The testes were weighed and changes in sperm count, motility, viability,
deformity, DNA integrity and chromatin quality were analyzed. Serum testosterone and
MDA concentrations of testicular tissue were determined. Data were analyzed by oneway ANOVA with p<0.05 as the significant level. Results STZ-induced diabetes decreased numerous reproductive parameters in rats. Testicular weight, sperm count, motility, viability and serum testosterone levels increased in
the diabetic group treated with RJ. There was a significant decrease observed in sperm
deformity, DNA integrity, chromatin quality, and tissue MDA levels in diabetic rats treated with RJ compared to the diabetic group (p<0.05). Conclusion RJ improved reproductive parameters such as testicular weight, sperm
count, viability, motility, deformity, DNA integrity, chromatin quality, serum testosterone
and testicular tissue MDA levels in diabetic rats.

Abstract
BACKGROUND Stanozolol (ST) is a synthetic anabolic-androgenic steroid often abused by athletes. An increasing body of evidence points towards the role of ST misuses in the pathogenesis of a wide range of adverse effects including reprotoxicity. OBJECTIVE The aim of this study was to analyze the possible reproprotective effect of royal jelly (RJ) as an efficient antioxidant in ST-treated mice. MATERIALS AND METHODS Adult male mice were divided into four groups (n=5). Two groups of mice received ST (4.6 mg/kg/day) via gavage for 35 days. RJ was given orally to one of these groups at the dose level of 100 mg/kg body weight per day synchronously. Untreated control group and RJ-only treated group were also included. Epididymal sperm characteristics and in vitro fertilizing capacity were evaluated after 35 days. RESULTS ST treatment caused a significant (p<0.05) decrease in sperm count and motility and fertilization rate along with poor blastocyst formation and increased sperm DNA damage. Moreover, the incidence of apoptosis and abnormality in spermatozoa was significantly (p<0.05) higher in ST-exposed mice than those of control. The above-mentioned parameters were restored to near normal level by RJ co-administration. CONCLUSION Data from the current study suggest that RJ has a potential repro-protective action against ST-induced reproductive toxicity in mice. However, clinical studies are warranted to investigate such an effect in human subjects.

Abstract
Abstract
Bioethanol has been found to be a suitable substitute for gasoline in internal combustion engines. It could be used either in an undiluted form or blended with gasoline. To blend the ethanol and gasoline, the water content of ethanol should reach 0.5% or less. In the present research work, 3A Zeolite was used as an absorbent with vacuum distillation. The effects of the operating parameters such as temperature, vacuum pressure and vapor flow rate on ethanol–water separation were investigated. Final ethanol concentration was obtained at the end of every run as well as the concentration of outlet ethanol. Both linear regression and ANN design were used to determine the best fit for two final parameters. The optimum condition was obtained at 0.4 bar vacuum pressure and 20 l/min ethanol–water vapor flow rate. ANN model is more qualified to the simulation of outspread data while the linear regression is not. L10L10 mode and L5T10 mode provide the best results for final concentration and total time, respectively. The Trainlm Algorithm like the previous research training algorithm is the best.

Abstract
BACKGROUND Leptin, as a 16 kDa adipokine, is a pleiotropic cytokine-like hormone that primarily secreted from adipose tissue. It also involves in the regulation of energy homeostasis, neuroendocrine function, immunity, lipid and glucose homeostasis, fatty acid oxidation, angiogenesis, puberty and reproduction. The aim of this study was to investigate the effects of in vitro addition of leptin to in vitro maturation (IVM) medium on buffalo oocyte maturation and apoptosis. MATERIALS AND METHODS In this experimental study, Ovaries from apparently normal reproductive organs of slaughtered adult buffaloes (Bubalus bubalis) with unknown breeding history were collected from Urmia Abattoir, Urmia, Iran, and were transported immediately to the laboratory in a thermos flask containing sterile normal saline with added antibiotics. Oocytes were aspirated from 2-8 mm visible follicles of the ovaries using an 18-G needle attached to a 10 ml syringe. IVM medium included tissue culture medium-199 (TCM-199), 10% fetal bovine serum (FBS), 22 µg/ml sodium pyruvate, 0.5 IU/ml ovine follicle-stimulating hormone (oFSH), 0.5 IU/ml ovine luteinizing hormone (oLH), 1 μg/ml oestradiol, 50 μg/ml gentamycin, and leptin [0 (control), 10, 50, and 100 ng/ml]. The good quality buffalo oocytes (batches of 10 oocytes) were placed in a culture plate containing six 50 μl droplets of maturation medium, covered with sterilized mineral oil, and then incubated at 38.5˚C with 5% CO2 in air for 24 hours. The maturation of oocytes was evaluated under a stereomicroscope by detecting the first polar body extrusion of oocytes. FITC-Annexin V propidium iodide (PI) staining method was used to detect oocyte apoptosis. RESULTS From a total of 115 collected ovaries, 1100 oocytes were recovered among which 283 oocyte were suitable for IVM. In the groups of leptin treated with 0 (control), 10, 50 and 100 ng/ml, the percentage of oocytes maturation was 74.65, 83.81, 77.85, and 75.40%, while the percentage of oocytes apoptosis was 9.83, 9.54, 9.93, and 10.42%, respectively. Our results showed that addition of 10 ng/ml leptin to buffalo IVM medium increased oocyte maturation, significantly, as compared with that in control group. However, addition of leptin to IVM medium had no significant influence on buffalo oocyte apoptosis. CONCLUSION Our findings suggested that addition of 10 ng/ml leptin to IVM medium of buffalo oocyte can improve oocyte nuclear maturation. Furthermore, we showed that there is no relation between in vitro addition of leptin to buffalo oocyte IVM medium and oocyte apoptos. CONCLUSION Our findings suggested that addition of 10 ng/ml leptin to IVM medium of buffalo oocyte can improve oocyte nuclear maturation. Furthermore, we showed that there is no relation between in vitro addition of leptin to buffalo oocyte IVM medium and oocyte apoptosis.

Abstract
UNLABELLED Objectives : The aim of the present study was to evaluate protective effect of royal jelly on sperm parameters, testosterone level, and malondialdehyde (MDA) production in mice. MATERIALS AND METHODS Thirty-two adult male NMRI mice weighing 30±2 g were used. All the animals were divided into 4 groups. CONTROL GROUP received saline 0.1 ml/mouse/day orally for 30 days. Royal jelly group (RJ): received royal jelly at dose of 100 mg/kg daily for 30 days orally. Oxymetholone group: the received Oxymetholone (OX) at dose of 5 mg/kg daily for 30 days orally. Royal jelly+Oxymetholone group: received royal jelly at dose of 100 mg/kg/day orally concomitant with OX administration. Sperm count, sperm motility, viability, maturity, and DNA integrity were analyzed. Furthermore, serum testosterone and MDA concentrations were determined. RESULTS In Oxymetholone group, sperm count, motility as well as testosterone concentration reduced significantly (p<0.05), while significant (p<0.05) increases in immature sperm, sperm with DNA damaged, and MDA concentration were announced in Oxymetholone group in comparison with control group and Royal jelly+Oxymetholone group. RJ caused partially amelioration in all of the above- mentioned parameters in Royal Jelly+Oxymetholone group. CONCLUSION In conclusion, RJ may be used in combination with OX to improve OX-induced oxidative stress and male infertility.

Abstract
The carotid is a small mass of chemoreceptor's and sustentacular cells that detects changes in the composition of the arterial blood. The aim of the present study was to identify the size, color, location, blood and nerve supply of the carotid body in Makouei sheep. Fourteen heads of sheep from both sexes were collected from Urmia public slaughter-house. The exact situation and nerve supply of the carotid body was determined. Before dissection, blue latex was injected into right and left common carotid arteries. All the branches of the common carotid artery and the branch supplying carotid body were investigated. This study showed that, carotid body in sheep has been situated around the muscular branch of the occipital artery. The mean weight, width and length, thickness of carotid body were 0.01 g, 0.83 mm, 1.07 mm, and 1.06 mm respectively. Blood to the carotid body was supplied by glomic artery which was a branch of occipital artery. It was innervated by herring nerve which was a branch of glossopharyngeal nerve.

Abstract
BACKGROUND Methotrexate (MTX) is an anti-metabolite drug widely used in treatment of neoplastic disorders, rheumatoid arthritis and psoriasis. The ester derivative, ethyl pyruvate (EP) is stable in solution and should function as an antioxidant and energy precursor. This study was conducted to evaluate the protective role of EP on sperm parameters, testosterone level and malondialdehyde (MDA) production in mice treated with MTX. METHODS 32 adult male NMRI mice weighing 26±2 g were divided into 4 groups. Group 1 received 0.1 ml/mice/day of distilled water intraperitoneally for 30 days (ip). Group 2 was treated with methotrexate at a dose of 20 mg/kg once a week (ip) for 30 days. Group 3 was treated with ethyl pyruvate at a dose of 40 mg/kg/daily (ip) for 30 days. Group 4 was treated with methotrexate (20 mg/kg) once a week simultaneously with ethyl pyruvate 40 mg/kg for 30 days. The results were analyzed by oneway ANOVA. A p<0.05 was considered to be significant. RESULTS The results showed significant (p<0.05) decrease in sperm count and sperm motility as well as testosterone concentration while sperm with damaged DNA and MDA concentration in mice treated with MTX in comparison with control and MX+EP groups increased significantly (p<0.05). Instead, MTX+EP group caused partial amelioration in all parameters mentioned above. CONCLUSION Based on the present study, it can be concluded that MTX induced toxicity in sperm parameters and serum level of testosterone and increased MDA level. EP with its antioxidant properties could be administrated during treatment with MTX due to its protective effects on sperm parameters, plasma testosterone levels and lipid peroxidation.

Abstract
The purpose of this study was to evaluate the probable effects of leptin addition in different levels to the semen extender on sperm quality (motility and motility parameters, viability, sperm membrane integrity, and DNA damage). Semen specimens were evaluated immediately after leptin addition, equilibration time and after thawing the frozen semen. Five healthy buffalo bulls (5 ejaculates from each bull) were used. Each ejaculate was diluted at 37 ˚C with tris-based extender containing 0 (control), 10, 20, 50, 100, and 200 ng mL(-1) leptin. The diluted semen was kept 4 hr in refrigerator to reach to the equilibration time and then packed in 0.5 mL French straws and frozen in liquid nitrogen. Our results showed that, in the fresh semen, no significant difference was observed in all sperm quality parameters evaluated among all of the examined leptin concentrations. Addition of 10 ng mL(-1) leptin into semen extender significantly preserved sperm motility, all of the motility parameters, and viability in equilibrated semen compared to that of control group. However, in vitro addition of 200 ng mL(-1) leptin, significantly decreased theses parameters. In the frozen thawed semen, all leptin concentrations decreased sperm motility and viability, but significant decrease was observed in concentrations of 100 and 200 ng mL(-1). Adding leptin to semen extender did not have any significant influence on sperm DNA damage and sperm membrane integrity in all examined groups. These findings suggest that in vitro addition of 10 ng mL(-1) leptin could preserve sperm motility and viability in cooled semen of buffaloes.

Abstract
Gibberellic acid (GA3) is a group of plant hormones identified in various plants. The aim of this study was to determine the effects of GA3 on sperm parameters and in vitro fertilization (IVF). Fifty six adult male rats were divided into seven groups as, control, treatment and sham. Following 15, 30 and 45 days of GA3 and methanol alcohol (MA) administration, rats were euthanized and epididymis tail was transferred to human tubular fluid (HTF) medium containing 4 mg mL(-1) bovine serum albumin (BSA) .Total number of sperms, the percentage of live sperms, immature sperms and sperms with damaged chromatin and IVF were examined. The oocytes were obtained from immature rats after the injection of pregnant mare's serum (PMSG) and human chorionic gonadotropin (HCG) hormones. Human tubular fluid was used as the fertilization medium and zygotes transferred to fresh 1-cell rat embryos culture medium (mR1ECM) to reach the blastocyst stage. This study showed that GA3 could decrease the number of total sperms on days 30 and 45 in treated group comparison with the control and sham groups. Additionally, GA3 increased the immature sperms and sperms with damaged chromatin. The percentage of fertilization, two-cell embryos and blastocyst resulting from the treatment group on days 30 and 45 also decreased and showed significant differences with the control and sham groups (p < 0.05). The results obtained from this study indicated that the oral use of GA3 could reduce the fertility in rats by influencing the sperm number and the quality of sperm's chromatins.
