The risk of type 2 Diabetes mellitus is constantly increasing and therefore it is necessary to seek effective and new therapies. Cornelian cherry (Cornus mas L.) presents an opportunity in an alternative for treatment of type 2 Diabetes mellitus due its high antioxidant effects. The objective of the study was to assess the effect of Cornelian cherry pulp and stone on ZDF rats, which are suitable biological model for type 2 diabetes. ZDF rats received Cornelian cherry in three doses (1500, 2000 mg kg-1 body weight of the pulp and 250 mg kg-1 body weight of the stone) using the sterile oral rodent gavage for 4 months. Blood glucose, insulin, antioxidant activity and compounds in Cornelian cherry were determined to investigate the effects. Cornelian cherry stone significantly decreased affected blood glucose levels in ZDF rats when compared to the untreated control group. Total polyphenols and phenolic acids had significantly higher values in Cornelian cherry stone against pulp. Also, high concentrations of the anthocyanins were determined in the pulp. The results suggest that Cornelian cherry stone would potentially provide promising source of natural antioxidants and use in the management of Diabetes mellitus.

Endocrine disruptors (EDCs) are chemicals that interfere with hormonal balance in both animals and humans, potentially leading to a wide range of health problems. This review explores how endocrine disruptors function, their sources, and their effects on human and animal health, including their impact on the reproductive system, metabolism, neuroendocrine function, and cancer progression. The aim of this review is to describe the mechanisms of action of endocrine disruptors, such as their interactions with hormonal receptors, induction of epigenetic changes, and effects on cell signaling pathways. Additionally, this work examines how endocrine disruptors influence physiological processes, evaluates the impact of nanoparticles on endocrine disruption, and discusses the body's defense mechanisms against these agents. Among the most well-known EDCs are bisphenol A (BPA) and phthalates, which have been linked to a wide range of health conditions. Recent studies have also highlighted the risks posed by nanoparticles, including microplastics and nanoplastics, which amplify endocrine disruption and disturb hormonal balance. Future research should focus on identifying molecular pathways affected by EDCs to mitigate their negative impact on the endocrine system.

Sodium fluoride (NaF), although helpful in preventing dental decay, may negatively affect the body. The aim of this study was to examine the effects of a 6-hin vitrotreatment of livers isolated from 14-day-old chicken embryos with NaF at doses of 1.7 (D1), 3.5 (D2), 7.1 (D3) and 14.2 mM (D4), with regard to apoptosis, cell proliferation and tissue structure. The mRNA expression of the apoptosis regulatorsCYCS,APAF1,BCL2,CASP3,CASP9andTMBIM1was analysed by the qPCR method. Apoptotic cells were detected by a TUNEL assay. The tissue and DNA structure were also analysed by histological staining (H&E, Feulgen). The number of proliferating cells was determined and the apoptosis regulatory proteins were localised by the immunohistochemical staining of PCNA, CASP3 and APAF1. The results showed that the mRNA expression ofCYCS,BCL2,CASP3,CASP9andAPAF1increased significantly in the D1 group, as did that ofCASP9in the D3 group and ofBCL2andAPAF1in the D4 group. The number of apoptotic cells increased significantly in the D4 group, where they increased from 18% to 49%. On the other hand, the number of proliferating cells decreased gradually, in a dose-dependent manner, from 84% in the control group to 5.5% in the D4 group. The expression of apoptosis-regulating factors also increased: in the D3 and D4 groups, the CASP3 immunopositive reaction was more intensive in single cells in the embryonic livers, whereas that of APAF1 increased in the hepatocytes as well as in the hepatic blood vessel walls. The mechanism of the effect of NaF on apoptosis in the embryonic liver is very complex. In the groups exposed to higher doses of NaF, apoptosis was significantly stimulated, while proliferation was inhibited and the tissue structure was damaged. The expression of apoptosis regulators at the mRNA and protein levels increased, but the mRNA expression did not depend on the NaF dose. These results reveal that NaF, by changing the balance between apoptosis and the proliferation of hepatocytes, may disturb the development and function of the liver in embryonic chickens. Therefore, the risk of exposure to NaF should be considered when determining the standards for human and animal exposure to this compound.

Over the course of the last 10 years, there has been a significant amount of advancement in the subject of nanotechnology, which has demonstrated a great deal of potential not only in the realm of technological fields but also in the realm of medical research. It is possible to see a broad variety of uses for zinc oxide nanoparticles (ZnO-NPs) in the field of cancer research, which is being conducted using nanotechnology. Despite the fact that scientific knowledge is continually expanding in terms of its comprehension of the molecular foundation of cancer cells, the number of people who are diagnosed with cancer continues to rise. The World Health Organisation (WHO) forecasted that the number of cancer cases will rapidly rise over the following ten years. ZnO-NPs have established themselves as a viable option for the treatment of cancer as a result of their capacity to trigger apoptosis in cancer cells. Due to the fact that ZnO nanoparticles have been shown to have anticancer, antibacterial, anti-diabetic, and anti-inflammatory activities, they have garnered a lot of interest in the field of biomedicine. The purpose of this study is to provide a summary of the recent research that have been conducted on the application of ZnO-NPS in the medical field.

The aim of this study was to evaluate the effect of the cholinergic receptor antagonists on ghrelin (GHRL) expression and release from parts of the gastrointestinal system in an unique animal model—newly hatched chickens. Ghrelin was released from explants of the crop, proventriculus, and duodenum tissues in vitro. The expression of GHRL, along with that of ghrelin O-acyltransferase (GOAT) and growth hormone secretagogue receptor (GHSR-1a), was also observed in the crop, proventriculus, and duodenum. This is the first report on ghrelin expression, synthesis, and release in the avian crop. The release and expression of ghrelin, together with ghrelin-related parameters (expression of GOAT and GHSR-1a), were influenced by incubation with cholinergic antagonists, particularly in gastrointestinal explants from chicks within 2 h of hatching. For instance, there was increased release of ghrelin from crop or proventriculus explants from newly hatched chicks in the presence of hexamethonium. In addition, the expressions of ghrelin, GOAT, and GHSR-1a were increased in the presence of hexamethonium in crop explants from newly hatched chicks. In contrast, the release of ghrelin from duodenal explants was decreased in the presence of either atropine or hexamethonium in both newly hatched and 1-day-old chicks. There were relationships between ghrelin release and expression and also with GOAT and GHSR-1a expression, particularly in crop explants from newly hatched chicks. For instance, there were strong relationships (adjusted R2 > 0.84) between the expression of ghrelin, GOAT, and GHSR in tissue incubated with cholinergic antagonists. This is a novel report demonstrating ghrelin release and synthesis from three regions of the avian gastrointestinal tract. It also demonstrates the cholinergic control of ghrelin release and synthesis.
