Abstract
Astaxanthin (ASX) is one of the keto-carotenoids, which is biologically more active than other counterparts. Besides its variety of beneficial effects, it was reported to exert anticancer effects. Despite its utilization against different cancer types, the effect of ASX on mesothelioma has yet to be well-studied. In this study, our goal is to ascertain how ASX will affect SPC212 human mesothelioma cells. First, the effective doses of ASX against SPC212 cells were investigated by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) test. Thereafter, with flow cytometry analysis, Annexin-V and caspase 3/7 assay were implemented for the evaluation of apoptotic cell death and an oxidative stress test was carried out to determine how the free radicals changed. Ultimately, the cells' morphology was examined under a light microscope. The effective doses of ASX were found as 50, 100, and 200 µM. In the Annexin V assay, the total apoptosis increased to around 12%, 30%, and 45% with increasing doses of ASX. In the caspase 3/7 assay, the total apoptosis was around 25% and 38% at 100 and 200 µM. In oxidative stress analysis, reactive oxygen species-positive cells rose from 4.54 at the lowest dose to 86.95 at the highest dose. In morphological analysis, cellular shrinkage, decrease in cell density, swelling and vacuolations in some cells, membrane blebbing, and apoptotic bodies are observed in ASX-treated cells. To conclude, the current study provided insights into the efficacy and effects of ASX against SPC212 mesothelioma cells regarding morphology, proliferation, and cell death for future studies.

Abstract
Hyperthyroidism influences the development of cardiac hypertrophy. Transient receptor potential canonical channels (TRPCs) and endoplasmic reticulum (ER) stress are regarded as critical pathways in cardiac hypertrophy. Hence, we aimed to identify the TRPCs associated with ER stress in hyperthyroidism-induced cardiac hypertrophy. Twenty adult Wistar albino male rats were used in the study. The control group was fed with standard food and tap water. The group with hyperthyroidism was also fed with standard rat food, along with tap water that contained 12 mg/L of thyroxine (T4) for 4 weeks. At the end of the fourth week, the serum-free triiodothyronine (T3), T4, and thyroid-stimulating hormone (TSH) levels of the groups were measured. The left ventricle of each rat was used for histochemistry, immunohistochemistry, Western blot, total antioxidant capacity (TAC), and total oxidant status (TOS) analysis. As per our results, activating transcription factor 6 (ATF-6), inositol-requiring kinase 1 (IRE-1), and TRPC1, which play a significant role in cardiac hypertrophy caused by hyperthyroidism, showed increased activation. Moreover, TOS and serum-free T3 levels increased, while TAC and TSH levels decreased. With the help of the literature review in our study, we could, for the first time, indicate that the increased activation of ATF-6, IRE-1, and TRPC1-induced deterioration of the Ca2+ ion balance leads to hypertrophy in hyperthyroidism due to heart failure.

Abstract
Despite the latest technologies and advances in microbiology and orthopedic surgery, chronic osteomyelitis is still a challenging disorder. Antibiotic resistance and bacterially induced bone destruction can have very serious consequences. We hypothesized that calcium phosphate-based bone graft substitution with silver ion doping would simultaneously treat bone infection and the bony defect in the chronic osteomyelitis. An unicortical 10-mm-diameter bone was harvested in the proximal tibial metaphysis of 24 rabbits. After contaminating the wounds with an infective dose of methicillin-resistant Staphylococcus aureus (MRSA), osteomyelitis was proven radiographically and microbiologically in all rabbits. Animals were than divided into three groups. The first group received vancomycin-impregnated bone cement beads (comparative control group), the second/experimental group received silver ion-doped calcium phosphate beads and the third group received pure calcium phosphate beads (negative controls). Radiographs, intraosseous cultures, and histopathological examinations were performed on postoperative Week 10. The cultures showed no evidence of intramedullary infection in the silver ion-doped calcium phosphate beads group, but they were positive for MRSA in four of the six rabbits in the vancomycin- impregnated bone cement beads group and in all of the eight rabbits in the pure calcium phosphate beads group. Quantitative assessment of histopathological examination showed lowest total damage score in silver ion-doped calcium phosphate beads group (p < .001). Percentage of osteoid tissue + bony tissue was also higher in this group compared with other groups. In the final radiological examinations, it was observed that the changes caused by osteomyelitis in the bone tissue in the silver ion-doped calcium phosphate beads group were much improved compared with the vancomycin-impregnated bone cement beads group. Silver ion doped calcium phosphate-based bone-graft substitute offer the ability to stimulate bone growth, combat infection, and, ultimately, treat experimental chronic osteomyelitis in an animal model.

Abstract
For centuries, Turkey has been a significant location here around 80 species of Hypericum with differing names widely occur, which is also known as Turkish folk medicine in treating some bacterial diseases as well as stomach and intestine inflammation. Recent studies have reported this herb family to contain numbers of bioactive compound contents. The study aims to investigate the protective effects of Hypericum triquetrifolium Turra (HT) upon oxidative stress and apoptosis in a rat model in which testes injury was induced by CP. The testicular injury was caused using CP (150 mg/kg). The rats were treated with a single dose (100 mg/kg) of methanol extract of HT to investigate various biochemical markers in the serum and plasma of blood samples apart from assessing the prognosis of CP-induced testicular damage. Added to that, histological analyses were performed to identify possible structural changes and apoptotic indicators, like Bax, Caspase-3, and Bcl-2. In CP Group, there was a rise in the levels of total oxidant status (TOS), malondialdehyde (MDA), oxidative stress index (OSI), Caspase-3, and Bax while superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), Bcl-2, and total antioxidant capacity (TAC) all decreased. Also, our histological analysis showed damaged testes. On the other hand, neither biochemical nor histological analysis showed testicular damage in HT Alone Group. In CP + HT Group, a significant number of the negatives changes due to CP were observed to have improved remarkably following an HT treatment. This study results suggest that HT could help improve CP-induced testicular injury thanks to its anti-oxidative and anti-apoptotic properties.

Abstract
BACKGROUND Quercetin found in fruits and vegetables has an antioxidative effect. We aimed to investigate the protective effects of quercetin according to different doses on hepatic and ischemia-reperfusion (I/R) injury. METHODS Fifty mature male Sprague-Dawley rats were randomly divided into five groups (n = 10 for each). All the animal groups underwent laparotomy. Group 1 rats served as a sham-operated group. Groups 2-5 underwent 1 h hepatic ischemia and were followed by 2 h reperfusion. Group 3-5 animals received an additional intraperitoneal dose of 25, 50 or 100 mg/kg quercetin respectively before I/R operation. Blood samples were collected for determining serum aspartate transaminase (AST), alanine transaminase (ALT) and malondialdehyde (MDA) levels. Also, liver tissue samples were taken for measuring of liver MDA concentration and for histopathology assessment. RESULTS The highest levels of biochemical parameters were observed in group 2. In quercetin-treated groups, serum AST, ALT, MDA levels, and tissue MDA concentration were decreased as inversely with increasing quercetin dose. Microscopic evaluation revealed that most conspicuous histological improvement was observed in 50 mg/kg quercetin co-treated rats. 25 and 100 mg/kg quercetin co-treatment could not protect completely against hepatic I/R injury. CONCLUSION Quercetin can be effective in preventing of hepatic I/R injury when the correct dose was used.

Abstract
BACKGROUND Acrylamide is a widespread substance having many areas of utilization. Besides, it also forms a part of high-temperature processed starchy foods. To date, numerous in vivo and in vitro studies have documented that acrylamide has toxic effects on various organ systems. AIMS To determine the potential protective effect of L-cysteine on acrylamide-induced testicular toxicity. STUDY DESIGN Animal experimentation. METHODS We randomly divided 28 rats into four groups as control (0.9% saline), L-cysteine (150 mg/kg), acrylamide (40 mg/kg) and acrylamide + L-cysteine. After a 10-day intraperitoneal injection period, we euthanized the animals, recorded their body and testis weights, collected blood samples for serum testosterone measurement, and excised testes for histopathological and morphometric evaluation. Besides, immunohistochemical scoring of proliferating cell nuclear antigen and bax proteins was performed. RESULTS Acrylamide reduced body (p<0.01) and testis weights (p<0.05), seminiferous tubule diameter (p<0.001) and proliferating cell nuclear antigen expression (p<0.05), while it increased bax protein expression (p<0.01) and the percentage of seminiferous tubules that contain multinucleated giant cells (p<0.001), but did not significantly change serum testosterone levels when compared to control. L-cysteine administered with acrylamide decreased multinucleated giant cell number (p<0.001) and reversed the reduced proliferating cell nuclear antigen positivity (p<0.001), but did not restore other parameters compared with the acrylamide alone-treated group. CONCLUSION Taking into account the dose and duration employed, the present study concluded that L-cysteine partially protects testis against acrylamide-induced toxic effects.

Abstract
INTRODUCTION It is known that sexual assault victim's contacting to water may decrease the detectability of sperm cells on the body of a victim. The features of water (i.e. chemical and biological) also have an importance in this respect. In this study, it is aimed at studying different kinds of water in terms of the detection of sperm cells in vitro. The difference of the study from other studies in the literature is the usage of different types of water and the search for detectability of sperm in these water samples regarding both time and dilution factor. MATERIALS AND METHODS After sexual abstinence, 30 volunteer young adults' ejaculate samples were taken with their informed consent. These samples were examined in liquid media in terms of change in time. Ejaculate samples which were standardized as to include 50 million sperms cells in each milliliter were diluted by 20% in 4 tubes including distilled water, tap water, sea water and river water. Sperm count in diluted samples was conducted daily. RESULTS It is determined that sperm cells can be detected after a longer time in tap and distilled water than in sea and fresh water. Sperm cells were detected up to 1128 h in tap water, 888 h in sea water, 1008 h in distilled water and 792 h in river water. Changes in sperm count in terms of dilution rate and liquid type were recorded. DISCUSSION AND CONCLUSION It is known that in vitro results are not the same as in vivo results. Time-dependent changes about detectability of sperm cells in different types of water are presented in tables and figures.
