Article Abstract
Purpose:: To evaluated histopathological changes, morphometric and expression of proteins CASPASE-3, BCL-2 and XIAP related to apoptosis in the cerebellum after induction of temporary focal cerebral ischemia followed by reperfusion, with or without a model of chronic alcoholism.
Methods:: Fifty Wistar rats were used and divided into: control group (C), sham group (S), ischemic group (I), alcoholic group (A), and ischemic and alcoholic group (IA). The cerebellum samples collected were stained for histopathological and morphometric analysis and immunohistochemistry study.
Results:: Histopathological changes were observed a greater degree in animals in groups A and IA. The morphometric study showed no difference in the amount of cells in the granular layer of the cerebellum between the groups. The expression of CASPASE-3 was higher than BCL-2 and XIAP in the groups A and IA.
Conclusion:: We observed correlation between histopathological changes and the occurrence of apoptosis in cerebellar cortex.
Background/aims: Gestational Diabetes Mellitus (GDM), a prevalent complication in pregnancy, is characterized by the Diabetes Association as diabetes diagnosed in the second or third trimester, often remaining asymptomatic. This study investigates the intricate effects of Streptozotocin on pregnant rats, unraveling its impact on Gestational Type 2 Diabetes (GTD). The research delves into the potential therapeutic roles of mesenchymal stem cells (MSCs) and olive leaf extract (OLE) in mitigating the consequences of Streptozotocin-induced pancreatic impairment.
Objective: To explore the antitumor effect of Inonotus obliquus extract on 4T1 tumor-bearing mice in vivo and its possible mechanism.
Methods: 4T1 tumor-bearing mice model was established. After successful modeling, tumor-bearing mice were randomly divided into model control group, cyclophosphamide(CTX) positive group, and high, medium and low dose groups of Inonotus obliquus extract, with 10 mice in each group, which were administered continuously for 21 days.
Optimal blood flow through a patent cerebral circulation is critical for supply of oxygen and nutrients for brain function. The integrity of vascular elements within arterial vessels of any calibre can be compromised by various disease processes. Pathological changes in the walls of veins and the venous system may also alter the dynamics of cerebral perfusion.

Background: Benign prostatic hyperplasia (BPH) is a disease linked to the hormonal imbalance that occurs during aging and over the last decades, complementary and alternative medicines have come on the scene as a treatment option for BPH, such as herbal medicines. Coconut oil has been shown to be capable of interfering in testosterone-induced BPH. However, until now there is no study of the effect of coconut oil during aging.
One neglected zoonotic illness is toxocariasis. There are not enough anthelmintic drugs in the market to treat low-effectiveness toxocariasis against migrating larvae. Therefore, it is critical to find new, safe alternatives to toxocariasis treatment today.
