Objectives: To determine the relation of hemostatic markers to cardiovascular fitness and adiposity and the effect of physical training (PT) on these markers.
Study Design: Seventy-four obese teenagers were randomly assigned to 8 months of lifestyle education (LSE), LSE plus moderate-intensity PT, or LSE plus high-intensity PT. Measures included fibrinogen, plasminogen activator inhibitor-1 (PAI-1), D-dimer, C-reactive protein (CRP), fitness, percent body fat (%BF), and visceral adiposity (VAT).
Results: At baseline, fibrinogen and CRP were significantly correlated with %BF and VAT (0.27
Conclusions: Unfavorable levels of fitness and adiposity were associated with higher levels of hemostatic markers, putting individuals with this profile at greater risk for future cardiovascular disease. No evidence was provided that 8 months of PT had a direct influence on these markers in obese youths.

Ultraviolet B (UVB) irradiation from sunlight is one of the primary environmental factors that causes photodamage to the skin. The aim of this study was to prepare succinyl-chitosan oligosaccharide (SU-COS) and evaluate its protective effects and related molecular mechanisms against UVB-induced photodamage for the first time. SU-COS (substitution degree: 69.

Neutrophils are peripheral blood-circulating leukocytes that play a pivotal role in host defense against bacterial pathogens which upon activation, they release web-like chromatin structures called neutrophil extracellular traps (NETs). Here, we analyzed and compared the importance of myeloid differentiation factor 88 (MYD88), peptidyl arginine deiminase 4 (PAD4), and gasdermin D (GSDMD) for NET formation in vivo following sepsis and neutrophilia challenge. Injection of lipopolysaccharide (LPS)/E.

In the current research, we developed a safe method using Iranian yarrow extract for the synthesis of silver nanoparticles (IY-AgNPs) as reducing and stabilizing agents in different conditions. The prepared and stabilized IY-AgNPs under optimal conditions were characterized using FT-IR, XRD, TEM, and UV-vis techniques. Also, the blood-clotting, hemolytic, antioxidant, bactericidal and, fungicidal properties, cytotoxicity effects and inhibition of protein denaturation efficiency of IY-AgNPs were assessed in vitro.

Background: Recently, silver nanoparticles (Ag-NPs) were shown to provoke oxidative stress through the release of reactive oxygen species and consequently induce cell damage. Selenium-loaded chitosan nanoparticles (CS-SeNPs) have anti-inflammatory and antioxidant effects, indicating that they ameliorate Ag-NPs-induced ovarian toxicity.
Objective: This study aimed to assess how well CS-SeNPs counteract the damaging effects of Ag-NPs on the ovarian tissue of adult female albino rats.

Aging is an inevitable aspect of life, but age-related diseases are not an inseparable part of the aging process, and their risk can be reduced through a healthy lifestyle. Vitamin K has a broader impact than just blood clotting, and yet it remains overshadowed by other vitamins and underestimated by both doctors and consumers. Vitamin K (VK) is a multifunctional micronutrient with anti-inflammatory and antioxidant properties, whose deficiency may cause age-related diseases such as cardiovascular diseases, neurodegenerative diseases and osteoporosis.
