Background: The skin is primarily affected by aging, especially when it is exposed to particulate matter present in the environment. It has been hypothesized that consumption of products with known antioxidant properties would help combat factors associated with both intrinsic and extrinsic aging factors.

Objective: The aim of the present study was to evaluate the effect of the formulation Blue Fenugreek Kale Extract (BFKE) on skin aging.

Despite the prominence of carbohydrate-specific antibodies in human sera, data on their emergence and antigen specificities are limited. Whereas maternal IgG are transferred prenatally to the fetal circulation, IgM present in cord blood originate from fetal B lymphocytes. Considering the limited exposure of the fetus to foreign antigens, we assessed the repertoire of carbohydrate-specific antibodies in human cord blood and matched maternal blood samples using glycan arrays.

Inflammatory bowel disease is associated with intestinal dysbiosis and with elevated antibody production toward microbial epitopes. The underlying processes linking the gut microbiota with inflammation are still unclear. Considering the constant induction of antibodies by gut microbial glycans, the aim of this study was to address whether the repertoire of carbohydrate-specific antibodies is altered in Crohn's disease or ulcerative colitis.

Carbohydrate-specific antibodies are widespread among all classes of immunoglobulins. Despite their broad occurrence, little is known about their formation and biological significance. Carbohydrate-specific antibodies are often classified as natural antibodies under the assumption that they arise without prior exposure to exogenous antigens.

Purpose: To examine the expression of fatty acid binding proteins (FABPs) at the human blood-brain barrier (BBB) and to assess their ability to bind lipophilic drugs.

Methods: mRNA and protein expression of FABP subtypes in immortalized human brain endothelial (hCMEC/D3) cells were examined by RT-qPCR and Western blot, respectively. FABPs that were found in hCMEC/D3 cells (hFABPs) were recombinantly expressed and purified from Escherichia coli C41(DE3) cells.
