Abstract Background Impaired deoxyribonucleic acid (DNA) repair may induce an autoimmune response in susceptible individuals. The association between DNA repair gene XRCC1 Arg399Gln gene polymorphism and susceptibility of systemic lupus erythematosus (SLE) is controversial. This study aimed to detect the association of XRCC1 Arg399Gln gene polymorphism with SLE and its clinical manifestations in the Egyptian population. Results A significant association was found between weight loss and genotype GG (P = 0.048); however, genotype AG was significantly associated with high serum creatinine and lo

TAFRO syndrome is a systemic inflammatory disorder of unknown etiology, and its diagnosis requires the exclusion of autoimmune diseases. A 42-year-old Japanese woman presented with TAFRO syndrome-like manifestations, but had undiagnosed limited-cutaneous systemic sclerosis preventing a definitive diagnosis of TAFRO syndrome. However, her clinical course and pathological findings, including renal glomerular microangiopathy, were consistent with TAFRO syndrome. We performed a systematic review of the literature to evaluate how autoimmunity affects the clinical characteristics of TAFRO syndrome/i

Continuous industrial productivity and modern societies have resulted in excess artificial light. The altered circadian rhythm causes many diseases. During intrauterine life, the mother's maternal melatonin rhythm has a major role in influencing organ development. The aim of this study was to investigate the effect of maternal exposure to constant light on the structure and ultrastructure of neonatal skin. Twenty pregnant New Zealand rabbits were divided into two groups (n=10 each): control group (12-h light/dark) and constant light group (24-h light). Plasma maternal melatonin and corticoster

Conversion of native habitats into agricultural monocultures is a major cause of biodiversity loss favouring a small number of generalist species. Rodents can cause significant declines in crop yield, hence understanding the factors affecting their population dynamics is of importance to the agricultural sector. Sugarcane plantations in African savannas harbour a low diversity of small mammals, with a single genus (Mastomys spp.) often dominating the community. Our study investigated the factors that shape the composition of the small mammal community and the life-history traits of the dominan

Serum creatinine has many limitations when being used to diagnose acute kidney injury (AKI), especially in the scope of intensive care unit due to its low sensitivity to depict the kidney dysfunctional level of critically-ill patients. Out of numerous new available biological markers, four biological markers are widely used all over the world to detect AKI, e.g. neutrophil gelatinase-associated lipocalin (NGAL), cystatin C, KIM-1, and interleukin-18.

Background: Hip abductor muscles play a critical role in stabilizing the pelvis during functional activities. A decline in hip abductor strength is associated with impaired balance and an increased risk of falls, particularly in elderly females who experience physiological changes and age-related muscle loss. Although limb dominance has been proposed to influence lower extremity muscle strength in young adults, no studies have yet examined differences in hip abductor strength between the dominant and non-dominant limbs in elderly females. Furthermore, the relationship between hip abductor stre
