Evaluating the blood toxicity of functionalized graphene-arginine with anticancer drug ginsenoside Rh2 in balb/c mouse model with breast cancer

Background: Gensenoside Rh2 is an anticancer drug with low toxicity and stability in the body. The aim of this study was to evaluate the blood toxicity of functionalized graphene-arginine with anticancer drug ginsenoside Rh2 in balb/c mouse model with breast cancer. Materials and Methods: Graphene-Arginine (G-Arg) and Graphene-Arginine-ginsenoside Rh2 (G-Arg-Rh2) were synthesized using microwave method. For evaluation of blood toxicity, 32 mice with breast tumors were randomly divided into 4 groups: control (3mg/kg 6 mg / kg PBS sterile), group 1 (6 mg / kg ginsenoside), group 2 (3 mg / kg G-Arg), and group 3 (3 mg / kg G-Arg-Rh2). Treatment was done intravenously once every three days for 32 days. Finally, blood factors were also examined by sampling from the heart. Results: Complete functionalization was proven by FTIR and Raman. Examination of blood factors showed that white blood cells had a very small increase. Anova test showed significant difference among four groups in term of WBC count (p=0.016). Pair sample T test showed that there was significant difference between control and group 1(p=0.036) and control and group 2 (p=0.036). There was no significant difference between control and group 3 (p=0.051). Other blood factors had no significant difference among examined groups (p>0.05). Conclusion: Based on results, after treatment with all designed nanostructures, only white blood cells had a very small increase and inflammatory reactions were statistically similar in all groups. This indicates the high efficiency of designed drug.

Prospects for assessing the biological and immunological age of a person by blood factors

According to the WHO, by 2050 in developed countries, the population over 60 years old will double. This will lead to a further increase in the retirement age and an elevation of burden on the health care system. Therefore, there is an acute issue of maintaining health and prolonging active longevity, as well as the introduction of monitoring for prevention of premature aging and age-related disorders to avoid early disability. The review aims to discuss the aging process and identify critical blood factors affecting or indicating progress in biological aging. The connection of biological age, the regenerative and immune systems aging with the shift in circulating blood factors have been evaluated. The concepts of "health and longevity hygiene" and the concept of "immunological age" are debated. Perspective methods of rapid and multiplex analyzes of blood factors are discussed, as well as the prospects for preliminary analysis of biological and immunological age at home with subsequent processing in high-tech centers to identify risk groups and monitor healthy aging. Approaches to protecting health, slowing aging and rejuvenating the elderly, maintaining healthy aging, and prolonging active life have been defined.

A Study to decrease the incidence of PPH in our hospital setting

Objective: This study aimed to measure incidence, identify risk factors (pre‐existing or acquired) forPPH and to prevent progression to severe PPH. Methods: This is a prospective observational study.The causes are likely to be multifactorial with shifting demography and health status widely cited,e.g. age, obesity, comorbidity, multiple pregnancy and ethnicity. Results: Prepregnancy factors forPPH include age, ethnicity, BMI, previous PPH and assisted conception Conclusion: Prophylacticuterotonic agents in high-risk patients, use of intramuscular or intravenous oxytocin, timelyapplication of B –lynch suture, adequate and timely arrangement of blood and blood factors can helpprevent PPH.

Can Blood-Circulating Factors Unveil and Delay Your Biological Aging?

According to the World Health Organization, the population of over 60 will double in the next 30 years in the developed countries, which will enforce a further raise of the retirement age and increase the burden on the healthcare system. Therefore, there is an acute issue of maintaining health and prolonging active working longevity, as well as implementation of early monitoring and prevention of premature aging and age-related disorders to avoid early disability. Traditional indicators of biological age are not always informative and often require extensive and expensive analysis. The study of blood factors is a simple and easily accessible way to assess individual health and supplement the traditional indicators of a person’s biological age with new objective criteria. With age, the processes of growth and development, tissue regeneration and repair decline; they are gradually replaced by enhanced catabolism, inflammatory cell activity, and insulin resistance. The number of senescent cells supporting the inflammatory loop rises; cellular clearance by autophagy and mitophagy slows down, resulting in mitochondrial and cellular damage and dysfunction. Monitoring of circulated blood factors not only reflects these processes, but also allows suggesting medical intervention to prevent or decelerate the development of age-related diseases. We review the age-related blood factors discussed in recent publications, as well as approaches to slowing aging for healthy and active longevity.

The role of physical activity on blood factors, lipid profile, and liver enzymes of tile factory workers (A Case Study)

Introduction: Inhalation of dust particles is prone to chronic diseases, and regular exercise reduces the risk of cardiovascular disease and improves blood variables. The purpose of this study was to investigate the role of physical activity on blood factors, lipid profile, and liver enzymes in tile factory workers. Materials and Methods: This is a cross-sectional study. 70 workers who were eligible to participate in the study were selected based on the sampling method available at the workplace. According to the Beck questionnaire, 15 people were included in each active and inactive groups. After 12 hours of worker's last meal, 10 ml of venous blood was used to evaluate biochemical variables of Blood factors (RBC, Hematocrit, Hemoglobin, WBC), lipid profile (Cholesterol, Triglyceride). Liver enzyme (ALT, AST, ALP) tests of both groups were performed in the occupational medicine laboratory of Meybod city, and SPSS Ver.23 software was used for analysis. Results: The results showed that red blood cells (p = 0.003) and hemoglobin (p = 0.034) in the active group were significantly higher than the inactive group. Also triglyceride (p = 0.025) and cholesterol (p = 0.042) of liver enzymes, (p = 0.011) ALT and AST (p = 0.047) were significantly lower. Conclusion: It seems that physical activity can have a positive effect; it can improve blood factors, liver enzymes, and fat profile in workers. According to the results, tile factory workers can achieve the desired blood factors with minimal physical activity.
