Background Anxiety disorders are common psychiatric disorders in childhood and an important health problem that is associated with the risk of serious mental, educational and economical problems. Researchers have mentioned many different mechanisms in the etiopathology of anxiety disorders. This study aimed to investigate ghrelin and leptin levels in children with anxiety disorders and thus to contribute to the clarification of anxiety in children. Methods Forty-three children aged 6-12 years with a diagnosis of the Anxiety Disorder according to DSM 5 and 21 healthy children age- and gender-matched to the study group were included. All the subjects were assessed with Kiddie Schedule for Affective Disorders and Schizophrenia Present and Lifetime Version (K-SADS-PL) and State-Trait Anxiety Inventory for Children (STAI-C) scale. Blood samples were obtained in the morning and serum ghrelin and leptin levels were measured with enzyme-linked immunosorbent assay (ELISA) kits. Results In the anxiety group the ghrelin levels were higher than the control group (p = 0.037) but there was no significant difference between the leptin levels (p = 0.430). Also, when the girls in the anxiety group and the girls in the control group were compared, ghrelin levels were higher in the anxiety group (p < 0.01). Conclusions These findings suggest that ghrelin may play a significant role in the etiologic mechanisms of anxiety disorders. However, more detailed studies are needed to explain the linkage between anxiety disorders and neuropeptides.

Obesity is a modifiable risk factor for breast cancer. Yet, how obesity contributes to cancer initiation is not fully understood. The goal of this study was to determine if the body mass index (BMI) and metabolic hallmarks of obesity are related to DNA damage in normal breast tissue.

Female obesity is a worldwide health issue linked to chronic metabolic low-grade inflammation (metaflammation) causing multiple obesity-related co-morbid conditions. We aimed to assess the serum levels of wingless integration site family member 5 A (Wnt5a), leptin, and tumor necrosis factor-alpha (TNF-α) as markers of obesity-associated metaflammation and investigate the association with toll-like receptors2 (TLR2) gene (Arg753Gln) single nucleotide polymorphism (SNP) among Egyptian females. The study included 60 females with obesity and 30 matched controls.

Background: Immunosenescence is accelerated by chronic infectious and autoimmune diseases and could contribute to the pathobiology of multiple sclerosis (MS). How MS and disease-modifying therapies (DMTs) impact age-sensitive immune biomarkers is only partially understood.
Methods: We analyzed 771 serum samples from 147 healthy controls and 289 people with MS (PwMS) by multiplex immunoassays.

The bone marrow (BM) niche is critical in regulating hematopoiesis, and sexual dimorphism and its underlying mechanism in BM niche and its impact on hematopoiesis are not well understood. We show that male mice exhibited a higher abundance of leptin-receptor-expressing mesenchymal stromal cells (LepR-MSCs) compared to female mice. Sex-mismatched co-culture and BM transplantation showed that the male BM niche provided superior support for in vitro colony formation and in vivo hematopoietic engraftment.

In addition to being linked to an excess of lipid accumulation in the liver, being overweight or obese can also result in disorders of lipid metabolism. There is limited understanding regarding whether different levels of protein intake within an energy-restricted diet affect liver lipid metabolism in overweight and obese rats and whether these effects differ by gender, despite the fact that both high protein intake and calorie restriction can improve intrahepatic lipid. The purpose of this study is to explore the effects and mechanisms of different protein intakes within a calorie-restricted diet on liver lipid metabolism, and to investigate whether these effects exhibit gender differences.
