Previous studies have shown catabolism of adenosine 5'-triphosphate (ATP) in systemic blood is a potential surrogate biomarker for cardiovascular toxicity. We compared the acute toxicity of high doses of doxorubicin (DOX) and isoproterenol (ISO) on hemodynamics and ATP catabolism in systemic circulation.

Sprague Dawley (SD) rats (n = 8 - 11) were each given either a single dose of 30 mg/kg ISO, or twice-daily dose of 10 mg/kg of DOX or normal saline (control) for 4 doses by subcutaneous injection. Blood samples were collected up to 6 hours for measuring concentrations of ATP and its catabolites. Hemodynmics was recorded continuously. Difference was considered significant at p < 0.05 (ANOVA).

Mortality was 1/8, 5/11 and 0/11 for the DOX, ISO and control groups, respectively. Systolic blood pressure was significantly lower in the DOX and ISO treated rats than in the control measured at the last recorded time (76 ± 9 for DOX vs 42 ± 8 for ISO vs 103 ± 5 mmHg for Control, p < 0.05 for all). Blood pressure fell gradually after the final injection for both DOX and control groups, but abruptly after ISO followed by a rebound and then gradual decline till the end of the experiment. Heart rate was significantly higher after ISO, but no difference between the DOX and control rats (p > 0.05). RBC concentrations of ADP and AMP, and plasma concentrations of adenosine and uric acid were significantly higher in the ISO group. In contrast, hypoxanthine concentrations were significantly higher in the DOX treated group (p < 0.05).

Acute cardiovascular toxicity induced by DOX and ISO may be measured by changes in hemodynamics and breakdown of ATP and adenosine in the systemic circulation, albeit a notable qualitative and quantitative difference was observed.

One of the most common complications of pregnant women is gestational diabetes mellitus (GDM). Oxidative stress can play an important role in GDM.

The aim of this study was to evaluate salivary antioxidants and oxidative stress markers in GDM.

Twenty pregnant women with GDM and 20 healthy pregnant women with normal blood glucose test participated in this study. Five mL of unstimulated saliva samples were collected. Spectrophotometric assay was carried out for sialochemical analysis. Stata software was used for data analysis.

The GDM group exhibited no significant difference in salivary total antioxidant capacity and malondialdehyde compared to the healthy control group. All of antioxidants markers, the uric acid, total antioxidant, peroxidase and catalase, decreased in GDM group that the difference of peroxidase and catalase was statistically significant. All of oxidative stress markers, the salivary malondyaldehid, total oxidative stress and total thiol, increased in GDM group. GDM group exhibited siood samples in GDM biomarkers changes.Berberine is an alkaloid found in plants. It has e.g. neuroprotective, anti-inflammatory and hypolipidemic activity. The research proves that it also strongly impacts the carbohydrate metabolism. The compound also protects pancreatic βcells and increases sensitivity to insulin in peripheral tissues via the induction of GLUT-1, GLUT-4 and insulin type 1 (Ins1) receptors activity. It also stimulates glycolysis and leads to a decrease in insulin resistance by macrophages polarization, lipolytic processes induction and energy expenditure enhancement (by reducing body mass and limiting insulin resistance caused by obesity). NF-κB inhibitor In liver berberine inhibits FOX01, SREBP1 and ChREBP pathways, and HNF-4α (hepatocyte nuclear factor 4 alpha) mRNA that hinder gluconeogenesis processes. In intestines it blocks α-glucosidase contributing to glucose absorption decrease. Its interference in intestinal flora reduces levels of monosaccharides and suppresses diabetes mellitus complications development.
Increased level of plasma homocysteine (Hcy) is a potential risk factor for several multi-system diseases. The Methylenetetrahydrofolate reductase (MTHFR) gene C677T variant has been established as an important genetic determinant of hyperhomocysteinemia. There are conflicting reports about the effects of physical activity on plasma Hcy. Therefore, the main aim of this study was to investigate whether the MTHFR C677T variant affects the elite athletic performance.

This study was carried out on 214 individuals (114 elite athletes and 100 sedentary controls). Genotyping was performed using PCR- RFLP method. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of association.

There was a significant difference between the athletes and the control group in genotype distribution and allele frequency of the MTHFR C677T variant. MTHFR C677T CC genotype and C allele were more prevalent in elite athletes than those in the sedentary controls (p =0.007, OR 2.16, 95%1.26-3.70; p=0.009, OR 1.84, 95%1.18-2.89, respectively). The control group had a higher MTHFR C677T CT genotype than the athletes had (p=0.019, OR 0.51, 95%0.30-0.88). There was no deviation from HWE for the MTHFR C677T variant in the groups.

Our findings support that there is an association between the MTHFR C677T C allele and athletic performance among the elite Turkish athletes.

Mesenchymal Stem Cells (MSCs) have a natural tendency to home in a tumor microenvironment and acts against it, owing to the similarity of the latter to an injured tissue environment. Several studies have confirmed the recruitment of MSCs by tumor through various cytokine signaling that brings about phenotypic changes to cancer cells, thereby promoting migration, invasion, and adhesion of cancer cells. The contrasting results on MSCs as a tool for cancer cytotherapy may be due to the complex cell to cell interaction in the tumor microenvironment, which involves various cell types such as cancer cells, immune cells, endothelial cells, and cancer stem cells. Cell to cell communication can be simple or complex and it is transmitted through various cytokines among multiple cell phenotypes, mechano-elasticity of the extra-cellular matrix surrounding the cancer cells, and hypoxic environments. In this article, the role of the extra-cellular matrix proteins and soluble mediators that acts as communicators between mesenchymal stem cells and cancer cells has been reviewed specifically for breast cancer, as it is the leading member of cancer malignancies. The comprehensive information may be beneficial in finding a new combinatorial cytotherapeutic strategy using MSCs by exploiting the cross-talk between mesenchymal stem cells and cancer cells for treating breast cancer.
The incidence of insulin resistance syndrome and type 2 diabetes mellitus has increased at an alarming rate worldwide and constitutes a serious challenge to public health care in the 21st century. Endocrine disrupting chemicals are defined as "substances or mixtures of substances that alter the endocrine system function[s] and, hence, adversely affect organisms, their progeny, or [sub] populations" and may be associated with this increase in prevalence.

This study aimed to assess the role of endocrine disrupting chemicals in insulin resistance and the importance of approaching the subject during anamnesis.

a full review of the literature regarding insulin resistance, type-2 diabetes and endocrine disruptors was conducted.

Large-scale production and distribution of endocrine disrupting chemicals coincide with the increase in prevalence of insulin resistance globally. In recent years, studies have shown that endocrine disrupting chemicals are positively associated with insulin resistance syndrome, evidenced by worse prognoses among individuals with higher levels of exposure. Health professionals should recognize the forms of exposure, most susceptible people, and lifestyle habits that can worsen patients' prognoses.

Chronotherapeutics, a branch of pharmacotherapeutics plays a mandate part in the treatment of various disorders, as delivering the drug in correct schedule, correct site, and in correct extent and provides benefit to the patients. The chronopharmacological aspects are very much important in the treatment of diabetes mellitus during daytime as the patients timing of activities of body and medicine treatment has an impact on the increase in the glucose levels in the blood. The fact that increased risk of obesity and diabetes is worse and rates of cardiovascular diseases and death rate is more. A medical savour who works on diabetic problem had been known that the level of glucose in plasma changes independently as regard to eating habits and use of insulin and medicines. People suffering from dawn process is difficult to manage hence the basic aim of a concept is how to detect the function of biological clock of human body, its chronotherapeutic effect on human beings that increases the therapeutic effects and reduces side effects. Keeping these points in mind an attempt has been made in the present review to discuss the role of chronotherapy in the management of diabetes, various techniques used in formulation and design of chronotherapeutic drug delivery systems and regulatory issues related to chronotherapeutics.
The biological dataset was retrieved from two series of α-glucosidase inhibitors synthesized by Rahim et al. and Taha et al. and consisted of a total 46 (forty-six) α-glucosidase inhibitors.
