Background and Aim: This study examined the effects of black cumin seed oil treatment on oxidative stress and the expression of radixin and moesin in the liver of experimental diabetic rats. Materials and Methods: Eighteen rats were divided into 3 equal groups (control, diabetes, treatment). The control group was not exposed to any experimental treatment. Streptozotocin was administered to the rats in the diabetes and treatment groups. A 2.5 mL/kg dose of black cumin seed oil was administered daily for 56 days to the treatment group. At the conclusion of the experiment, the blood level of malondialdehyde (MDA) and glutathione (GSH) was measured. The expression level and the cellular distribution of radixin and moesin in the liver were analyzed. Results: The plasma MDA (3.05±0.45 nmol/mL) and GSH (78.49±20.45 μmol/L) levels in the diabetes group were significantly different (p0.05) and moesin expression was significantly downregulated (p

A need exists for a safe and effective oral preanaesthetic medication for use in children undergoing elective surgery. The study sought to define the dose of oral ketamine that would facilitate induction of anaesthesia without causing significant side-effects. We studied 80 children undergoing elective surgery under general anaesthesia who received oral ketamine 4, 6 or 8 mg kg(-1) in a prospective, randomized, double-blind placebo controlled study. We compared the reaction to separation from parents, transport to the operating room, the response to intravenous cannula insertion and application of an anaesthetic facemask, the induction of anaesthesia and recovery from anaesthesia. In the group receiving ketamine 8 mg kg(-1), the children were significantly calmer than those of the other groups, and anaesthesia induction was more comfortable. Recovery from anaesthesia was longer in the group receiving ketamine 8 mg kg(-1) compared with the other groups, but no differences between the groups were observed after 2 h in the recovery room. It is concluded that oral ketamine 8 mg kg(-1) is an effective oral premedication in inpatient children undergoing elective surgery.

In this study we aimed to examine the effect of novel vasodilatory drug Riociguat co-administration along resveratrol to recover neurodegeneration in experimental stroke injury. For that purpose, thirty-five adult female rats were divided into five groups (Control, MCAO, MCAO + R, MCAO + BAY, MCAO + C) of seven animals in each. Animals in Control group did not expose to any application during the experiment and sacrificed at the end of the study. Rats in the rest groups exposed to middle cerebral artery occlusion (MCAO) induced ischemic stroke. MCAO + R group received 30 mg/kg resveratrol, and MCAO + BAY group received 10 mg/kg Riociguat. The MCAO + C group received both drugs simultaneously. The drugs were administered just before the reperfusion, and the additional doses were administered 24h, and 48h hours of reperfusion. All animals in this study were sacrificed at the 72nd hour of experiment. Total brains were received for analysis. Results of this experiment indicated that MCAO led to severe injury in cerebral structure. Bax, IL-6 and IL-1ß tissue levels were up-regulated, but anti-apoptotic Bcl-2 immunoexpression was suppressed (p<0.05). In resveratrol and Riociguat treated animals, the neurodegenerations and apoptosis and inflammation associated protein expressions were improved compared to MCAO group, but the most success was obtained in combined treatment exposed animals in MCAO + C group. This study indicated that the novel soluble guanylate stimulator Riociguat is not only a potent neuroprotective drug in MCAO induced stroke, but also synergistic administration of Riociguat along with resveratrol have potential to increase the neuroprotective effect of resveratrol in experimental cerebral stroke exposed rats.

Yapay zeka (YZ), son yıllarda biyomedikal alanlarda, özellikle de yardımcı üreme teknikleri (YÜT) içinde önemli bir yer edinmiştir. YÜT, infertilite tedavisinde kullanılan yöntemleri kapsar ve süreçlerin optimize edilmesi için YZ' nin entegrasyonu büyük bir potansiyele sahiptir. YZ kullanımı, sperm analizi, oosit kalitesinin değerlendirilmesi ve embriyo seçimi gibi kritik aşamalarda önemli iyileştirmeler sağlamaktadır. Ayrıca, bu süreçlerin daha hassas ve doğru bir şekilde yönetilmesine olanak tanırken, kişiselleştirilmiş tedavi yaklaşımlarının uygulanmasını da kolaylaştırır. YZ destekli sistemler, infertilite tedavisinde başarı oranlarını artırabilir, maliyetleri düşürebilir ve klinik sonuçları iyileştirebilir. YÜT alanında YZ' nin entegrasyonunun, gelecekte daha verimli ve etkili tedavi süreçlerinin geliştirilmesine katkı sağlayacağı öngörülmektedir.

Background: Preeclampsia is a pregnancy complication with a high morbidity and mortality rate.BAX is a proapoptotic protein and in recent years, 14-3-3 tau proteins are considered as key regulators of many processes, such as apoptosis. In this study, we investigated the expression of phospho-tau and Bax in preeclampsia apoptosis immunohistochemically. Materials and Methods: 25 healthy and 25 preeclamptic pregnant placentas were included in the study. Placental samples were fixed with 10% neutral buffered formalin. Routine paraffin wax tissue protocol was used. Results: According to histological micrograf, the trophoblastic cells in the villi were normal in the control group. Mild dilatation in blood vessels was seen. Hyalinized and necrotic areas in chorionic villi and an increase in fibrinoid tissue in root villi were detected in preeclampsia sections. Phospho-tau and Bax primary antibodys were used for immunohistochemical evaluation. The sections from of the preeclampsia group were highly positive for syncytiotrophoblasts and villous connective tissue. It was also statistically different from the control group (p<0.05). Conclusions: When we evaluate the results shows that Phospho-tau and Bax may be determinant proteins in the apoptosis pathway of preeclampsia.
