Abstract
In the present study, the main objective was to reveal whether treatment by Omega-3 fatty acids could prevent the adverse effects of adolescent nicotine withdrawal on spatial and avoidance memory in male rats. For this purpose, Morris water maze and passive avoidance tests were performed on male Wistar rats and the hippocampal levels of oxidative stress markers, inflammatory indices, brain-derived neurotrophic factor, nitrite, amyloid-B and acetylcholinesterase (AChE) were measured. Moreover, density of dark neurons were assessed in CA1 and CA3 regions. Results showed that adolescent nicotine exposure followed by a period of drug cessation exacerbates the behavioral indices of learning and memory through affecting a variety of biochemical markers within the hippocampal tissues. These changes lead to elevation of oxidative and inflammatory markers, reduction of neurotrophic capacity and increased AChE activity in hippocampal tissues. In addition, it was observed that co-administration of nicotine with Omega-3 fatty acids significantly prevents nicotine withdrawal-induced adverse effects through restoration of the mentioned biochemical disturbances. Therefore, we suggest administration of Omega-3 fatty acids as a safe, inexpensive and effective therapeutic strategy for prevention of memory dysfunctions associated with nicotine abstinence during adolescence.

Abstract
Objective The current study aimed to investigate whether Cocos nucifera L. oil (CO) is effective on menopause-related memory dysfunction in ovariectomized (OVX) rats. Materials and Methods Fifty healthy female Wistar rats were randomly selected and classified into five groups as control, OVX rats, and three OVX groups of rats which received three different doses (100, 200, and 400 mg/kg/day) of CO for five consecutive weeks by gavage. To assess the effect of CO, neurobehavioral tests such as Morris water maze (MWM) and Passive avoidance (PA) were done and then the animals were sacrificed to remove cortical and hippocampal tissues for biochemical analysis. Results In both behavioral tests including MWM and PA, treatment with CO particularly two higher doses of 200, and 400 mg/kg demonstrated significant improvement in comparison with OVX group. Furthermore, antioxidant biomarkers such as total thiol content, catalase and superoxide dismutase (SOD) activities were significantly higher in the OVX-CO groups versus the OVX group. On the contrary, malondialdehyde (MDA) concentration as an oxidative stress biomarker was remarkably lower in the OVX-CO200 and 400 mg groups than the OVX group. Conclusion The present study demonstrated the significant improvement of CO on learning and memory impairment induced by ovariectomy. Although the exact mechanism needs further investigation, it might have occurred due to the anti-oxidative effect of CO.

Abstract
BACKGROUND Despite its vast spectrum of clinical usage, cyclophosphamide (CP) exerts many adverse impacts, including hepatotoxicity. Antioxidant properties of ghrelin might protect the liver from CP-induced toxicity. The current study aimed to assess the protective impacts of ghrelin on CP-induced liver toxicity. METHODS Forty male mice were randomly divided into four groups (n=10) Group 1 as control received no intervention,group 2 received cyclophosphamide (CP) (100 mg/kg, i.p.) for five weeks and once a week. Group 3 received CP+ghrelin (CP+G), (80 µg/kg daily, i.p.) for five weeks. Group 4 received ghrelin with above-mentioned dose. At the end of the experiment, the mice were sacrificed to remove liver tissuesfor histological and biochemical examination. RESULTS Malondialdehyde (MDA) level increased after CP treatment but ghrelin administration significantly decreased the level of MDA (P<0.05). Measurement of the total antioxidant capacity (TAC) noted a significant decrease in the CP group against the control group (P<0.05). Ghrelin treatment in the CP+G group considerably increased the TAC activity when compared to the CP group (P<0.05). Histological examinations also confirmed the hepatocyte necrosis, local bleeding and inflammation, vacuolation, and sinusoidal dilation in the CP group, ghrelin administration reduced the destructive effects of CP on the liver significantly (P<0.05). CONCLUSION Our results reveal the hepatoprotective effect of ghrelin against CP. Therefore, ghrelin might be useful in protecting the body against the adverse impacts of injuries induced by chemotherapeutic drugs.

Abstract
Coronavirus disease 2019 (SARS-CoV-2) (COVID-19) has recently raised worldwide public health concerns. The available data on COVID-19 in patients with diabetes is limited but generally indicate that there is an increased risk of developing COVID-19 infection in diabetic patients, which ultimately impacts the overall patient's survival. Various aspects might be involved; however, the exact mechanisms and interrelationships between diabetes and the novel COVID-19 have not yet been fully elucidated. This review summarizes the possible mechanisms by which present diabetes predispose individuals to COVID-19 infection, modulates the hostviral interactions and increases the risk of mortality. We hope this review can provide beneficial information for further studies and contribute to improved disease management of diabetic patients with COVID-19.

Abstract
Colorectal cancer (CRC) is one of the most common leading causes of cancer death in the world. Although EGFR inhibitors have established efficacy in metastatic colorectal cancer (mCRC), some patients do not respond to this treatment. The EGFR inhibitors' failure and acquired resistance are partly due to KRAS and BRAF mutations. Thus, prognostic biomarkers that help to select eligible patients are highly in demand. To improve patient selection, assessment of mutational status in circulating cell free DNA (cfDNA), which possibly represents the dynamicity of tumor genetic status better than tumor tissue, could be advantageous. This review summarizes the current knowledge of the prognostic value of cfDNA in patients with mCRC treated with EGFR inhibitors with emphasis on the clinical importance of identification of KRAS and BRAF mutations.

Abstract
In human, there is substantial neurogenesis in the hippocampus that is implicated in memory formation and learning. These new-born neurons can be affected by neuropathological conditions. Anesthesia and surgical procedures are associated with postoperative cognitive changes particularly, impaired memory and learning. Therefore, the aim of this study was to evaluate the possible neurodegenerative effects of etomidate in rat hippocampus. Thirty male Wistar rats weighing 250 ± 30 g were randomly divided into 3 groups: 1) Etomidate group; four times 20 mg intraperitoneal injection with 1-h intervals, 2) Control group; the equal volume of normal saline, and 3) Normal group; without any intervention. 6 h after the last injection, the brains were removed and processed according to routine histological methods. TUNEL assay and toluidine blue staining were performed to evaluate neuro-histopathological changes in different regions of hippocampus. Our results showed that the number of TUNEL positive cells and dark neurons (DNs) in etomidate group were significantly higher in the CA1, CA2, CA3, and dentate gyrus (DG) of hippocampus compared with the control and normal groups (p < 0.05). While, there was no significant difference between the various regions of hippocampus in control and normal groups. Our findings showed that etomidate can increase apoptotic cells and dark neurons induction in different regions of hippocampus mainly in DG.

Abstract
The deteriorating effects of Lead (Pb) on central nervous system (CNS) such as cerebellum has been demonstrated in previous studies. Glycoconjugates with the important role in CNS development may be affected by Pb-exposure. Utilization of antioxidant agents and herbal plants has attracted a great deal of attention on attenuating neurotoxicants-induced damage. Thus, in this study the neuroprotective effects of vitamin C and garlic on content of glycoconjugates of cerebellar cortex in Pb-exposed animals were investigated. Wistar pregnant rats were divided into: control (C), Pb-exposed (Pb) (1500 ppm lead acetate in drinking water), Pb plus vitamin C (Pb + Vit C) (500 mg/kg) intraperitoneally, Pb plus garlic (Pb + G) (1 mL /100 g body weight fresh garlic juice via gavage), Pb plus vitamin C and garlic (Pb + Vit C + G), and sham groups (Sh). Finally, levels of Pb in blood were measured in both rats and offspring on postnatal day 50 (PND50). Also, the cerebellums were removed for measuring Pb-levels and performing lectin histochemistry. Blood and cerebellar Pb-levels were increased in Pb-exposed group compared to control group (P < 0.001), whereas they were decreased significantly in Pb + Vit C, Pb + G, and Pb + Vit C + G groups (P < 0.01). By using MPA, UEA-1, and WGA lectin histochemistry, Pb-exposed group showed weak staining intensity compared to other groups. Besides, significant decrease was observed in the density of lectin-positive neurons of Pb-exposed group compared to the control group (P < 0.001). Moreover, strong staining intensity and high lectin-positive neurons were found in Pb + Vit C, Pb + G and Pb + Vit C + G groups than Pb-exposed group (P < 0.001). The present study revealed that Pb-exposure can result in alteration in the cerebellar glycoconjugates contents and co-administration of vitamin C and garlic could attenuate the adverse effects of Pb. The findings of this study revealed the ameliorating effects of vitamin C and garlic against Pb, suggesting the potential use of vitamin C and garlic as preventive agents in Pb poisoning.

Abstract
Diabetes is a disease associated with impairment of the male reproductive system that causes complications such as decreased testosterone, the diameter of the seminiferous tubule, libido, and fertility. Extracellular matrix (ECM) molecules are involved in testicular development and spermatogenesis. Laminin and collagen are key proteins in seminiferous tubule basement membrane and play an important role in spermatogenesis. The present study was conducted to investigate the effect of diabetes on collagen IV and laminin α5 changes in mice testis. In this experimental study, 40 mice (C57BL/6) were divided randomly into 4 groups: 1) Control group: without intervention, 2) Diabetic group: treated mice with 50 mg/kg streptozotocin (STZ), 3) Diabetic + Insulin group: treated mice with STZ and insulin, and 4) Sham group: received citrate buffer. After 35 days, the left testes of all specimens were used for Real-Time PCR while their right testes were applied for immunohistochemical study and Periodic acid-Schiff (PAS) staining. This study showed that gene expression and immunoreactivity of laminin α5 and collagen IV were significantly increased in diabetic mice compared to other groups (P<0.05). Also, PAS staining showed the thickness of seminiferous tubule basement membrane in the Diabetic group compared to other group increased significantly (p<0.05). In Diabetic + Insulin compared to Diabetic group, gene expression, the intensity of immunoreactivity and thickness of seminiferous tubule basement membrane decreased significantly (P<0.05). Our findings indicated that diabetes causes up-regulation of collagen IV and laminin α5 in mRNA and protein levels in the seminiferous tubule basement membrane and may cause disorder in spermatogenesis in mice.

Abstract
There is an evident relationship between the fertilizing capacity of sperm and the normal morphology, quality chromatin, and motility of sperm. It is well known that thyroid hormones are the important regulators of testicular function. A correlation was found between the hypothyroidism and sperm damages. The present study was conducted to investigate the effects of hypothyroidism on sperm morphology, chromatin quality, and motility. For this purpose, 20 male mice were divided into the control and the hypothyroid groups that received 0.05% 6-n-propyl-2-thiouracil (PTU) for 35 days. Sperm morphology with Papanicolaou staining and sperm chromatin quality with both Aniline Blue (AB) and Toluidine blue (TB) staining were assessed. Besides, immunohistochemistry and real-time PCR were performed to evaluate the changes of cation sperm channel (CatSper) genes. A significant increase in the sperm chromatin condensation was found in the hypothyroid mice compared to the control mice (p < 0.05). Furthermore, a significant decrease was observed in the morphology of normal sperm in hypothyroid mice compared to the controls (p < 0.05). The results showed that Hypothyroidism could downregulate the expression of CatSper genes. Immunohistochemical data confirmed the real time-PCR results. Furthermore, the results showed that hypothyroidism could adversely affect sperm morphology, sperm chromatin condensation, and CatSper gene expression in mice and these abnormalities may be related to the excessive production of reactive oxygen species (ROS) in a hypothyroid state.

Abstract
INTRODUCTION Lead toxicity induces retinal cell apoptosis. Vitamin C and garlic may decrease lead-induced apoptosis. This study was undertaken to investigate vitamin C and garlic protective effects on lead-induced apoptosis in eye retina. METHODS Pregnant Wistar rats (n = 72) were divided randomly into 9 groups: (L) treated rats with lead acetate in drinking water and (L+AA) with leaded water and vitamin C intraperitoneally;(L+G), the rats received leaded-water and garlic juice via gavage; (L+AA+G) treated rats with leaded water, ascorbic acid, and garlic juice, (AA) with ascorbic acid, and (G) with garlic juice; (AA+G) treated rats with vitamin C and garlic juice and (Sh) with tap water plus normal hydrogen chloride (HCl) and glucose; normal (N). After 21-day lactation, blood lead level (BLL) in rats was measured, and then their offspring and the rat offspring's eyes were removed and processed for using TUNEL method. TUNEL positive cells in the eye retina were counted and all groups were compared. RESULTS BLL increased in L group compared to the control groups and decreased significantly in L + G, L + AA, and L+ AA + G groups compared to L group (P<0.05). TUNELL positive cell number in eye retina significantly increased in L group compared to control groups (P<0.05) and decreased in L+ G, L+ AA, and L+AA + G groups compared to L group (P<0.05). CONCLUSION Garlic juice and ascorbic acid administration during pregnancy and lactation may protect lead-induced apoptosis in rat offspring's eye retina.
