Lei Huang, Aman Xu
To date, gastric carcinoma (GC) is one of the common and fatal digestive malignancies worldwide. The prognosis of GC is not always satisfactory because of late diagnosis. Scholars are keen on discovering novel accurate and economical biomarkers in body liquids for GC screening to detect and evaluate the lesion before the results of imaging techniques are obtained. While traditional serum assays have limited sensitivity and specificity, gastrointestinal juice may provide relevant specific biomarkers because of its close contact with the tumor...

OBJECTIVE: Season of birth has repeatedly been found to be a risk indicator for adverse neurodevelopmental outcomes. Several explanations for this finding have been put forward but no conclusion has been reached. In the current study, we explored the role of sociodemographic and biological factors in the association between season of birth and child IQ. DESIGN: In a prenatally recruited birth cohort (born in 2002-2006), we examined the association between season of birth and non-verbal IQ at age 6 years among 6034 children...

Considerable epidemiological evidence suggests that high levels of circulating vitamin D (VD) are associated with a decreased incidence and increased survival from cancer, i.e., VD may possess anti-cancer properties. The aim of this investigation was therefore to investigate the anti-cancer potential of a low calcemic vitamin D analogue, i.e., inecalcitol and compare it with the active form of vitamin D, i.e., calcitriol, in a panel of breast cancer cell lines (n = 15). Using the MTT assay, IC50 concentrations for response to calcitriol varied from 0...

BACKGROUND: Fibroblast growth factor (FGF23) is a protein that is produced by osteoblasts and osteocytes. Increased serum levels of FGF23 have been associated with increased risks of osteoporotic fractures and cardiovascular disease, particularly in participants with poor renal function. Serum iron (Fe) has been suggested as a regulator of FGF23 homeostasis. OBJECTIVE: To determine whether Fe and iron status are determinants of the levels of intact FGF23 (iFGF23) in elderly men...

Cellular immunosuppression appears to be involved in sepsis and sepsis-induced multiple organ dysfunction syndrome (MODS). Recent evidence showed that parenteral vitamin C (Vit C) had the ability to attenuate sepsis and sepsis-induced MODS. Herein, we investigated the impact of parenteral Vit C on cellular immunosuppression and the therapeutic value in sepsis. Using cecal ligation and puncture (CLP), sepsis was induced in WT and Gulo(-/-) mice followed with 200 mg/Kg parenteral Vit C administration. The immunologic functions of CD4(+)CD25(+) regulatory T cells (Tregs) and CD4(+)CD25(-) T cells, as well as the organ functions, were determined...

BACKGROUND: Horse serum-induced immune complex coronary vasculitis in swine is the first experimental model to mimic most of the pictures of Kawasaki disease. Immune complex mechanism has been implicated as one of the possible mechanisms in the pathogenesis of vasculitis in Kawasaki disease. Antioxidants have a significant role in the reduction of cardiovascular diseases in both human and animal studies. We tried giving vitamins A, E, and C to treat immune complex vasculitis, in the hope of mitigating coronary vasculitis in Kawasaki disease...

Few studies have examined how vitamin C status is affected in diabetic pregnancy and no comparison between normal and diabetic pregnancies has been found. This study evaluated vitamin C status prospectively during pregnancy in women with type 1 diabetes mellitus (n=76), in non-diabetic women (n=60), and in their respective neonates. Vitamin C was lower in diabetic women throughout all trimesters compared to controls (p<0.01). Repeated measurements analysis showed significant differences between diabetic and non-diabetic women; also when adjusted for birth weight ratio and age...

Vitamin B12 is a cofactor for many enzymes but it also functions as a catalyst in C-C bond forming reactions. In the present study, the impact of corrin structural modifications on their catalytic efficacy was examined. Derivatives with various substituents at c-, d-, and meso-positions were synthesized using traditional and new microwave methodologies and then tested in the model reaction of 1,1-diphenylethylene with EDA. To complement our experimental data, CV and DFT calculations were performed. Mainly alterations at the c- or d-positions influence both the reaction yield and selectivity...

: In pre-pubertal girls, nutrient intakes and non-aquatic organized activity were evaluated as factors in vertebral body bone mass, structure, and strength. Activity, vitamin B12, and dietary fiber predicted bone outcomes most consistently. Exercise and vitamin B12 appear beneficial, whereas high fiber intake appears to be adverse for vertebral body development. PURPOSE: Childhood development sets the baseline for adult fracture risk. Most studies evaluate development using postero-anterior (PA) dual-energy X-ray absorptiometry (DXA) areal bone mineral density, bone mineral content, and bone mineral apparent density...
