The kinetics of the plasmacellular response in the draining lymph node was quantitatively assessed in specific-pathogen-free C3H/He mice grafted S.C. with the syngeneic BP-8 fibrosarcoma. The percentage of plasma cells was estimated on dissociated, cytocentrifuged, and fixed cell preparations by immunoenzymatic staining with either of two B-cell-specific antibody markers. Mice either grafted wi...

Algal filtrate and homogenate, obtained from Baltic seaweeds, were applied in seedling growth tests. Radish seeds were used in order to assess algal products phytotoxicity and their biostimulant effect on growth and nutrient uptake. Algal filtrate, at concentrations ranging from 5.0% to 100% was used for seed soaking and as a liquid biostimulant (soil and foliar application). Algal homogenate w...

alzheimer’s disease (ad) is a neurodegenerative disease that is the most common type of dementia.ad includes 60_80% of dementia and most people with ad have more than 65 years old.ad causes losing neuronal activity by abnormal proteins. plaques of beta-amyloid and tangles of “tau” protein can lead to ad. recently evidence has found that ad may come from outside of central nervous system (cns) a...

The current study deals with a digestive α-amylase in the larvae of Pieris brassicae L. through purification, enzymatic characterization, gene expression, and in vivo effect of a specific inhibitor, Acarbose. Although α-amylase activity was the highest in the whole gut homogenate of larvae but compartmentalization of amylolytic activity showed an equal activity in posterior midgut (PM) and ante...

It has been demonstrated by many workers (l-5) that phenols may be conjugated with glucuronic acid or inorganic sulfate in vitro by liver slices and by cell-free preparations. By using a system developed in this laboratory, together with a modification of the analytical procedure described by Levvy and Storey (3), the synthesis of the conjugated sulfate, and possibly of the glucuronide, has bee...

BACKGROUND Multiple sclerosis is a human autoimmunological disease that causes neurodegeneration. One of the potential ways to stop its development is induction of oral tolerance, whose effect lies in decreasing immune response to the fed antigen. It was shown in animal models that administration of specific epitopes of the three main myelin proteins - myelin oligodendrocyte glycoprotein (MOG),...

Fish inhabiting metal-contaminated environments can take up metals such as Cu via the gills as well as via the gut. Previous research on rainbow trout (Oncorhynchus mykiss) has indicated that dietary Na can reduce the accumulation of waterborne Cu; however, in hard water, dietary Na does not reduce the accumulation of dietary Cu. In this study, we exposed juvenile rainbow trout in soft water wi...
