Dimensional and concentration dependences of diffusion of aqueous alkaline-earth metal nitrate solutions in porous-glass membranes

Diffusion coefficients characterizing penetration of aqueous solutions of magnesium, calcium, strontium, and barium nitrates across porous-glass membranes with predominant pore radii of 4.5–70 nm were determined. A decrease in the pore radii of the membranes is accompanied in all cases by an exponential fall of the diffusion mobility. A reversal of the diffusion mobility series was observed for membranes with pore radii of 4.5 and 70 nm on the background of the general tendency toward a concentration-related rise in the diffusion coefficients.     

Mechanochemical Modification of Deoxypeganine Hydrochloride by Polyampholite

The solubility and dialysis of deoxypeganine hydrochloride and natural polyampholite were studied by IR spectra and x-ray diffraction analysis. Inclusion complexes form during mechanical treatment of a 1:1 mixture of deoxypeganine hydrochloride and natural polyampholite     

Four Questions on Birkhoff Polytope

We ask several questions on the structure of the polytope P_n of doubly stochastic n 2 n matrices, known as a Birkhoff polytope. We discuss the volume of P_n, the work of the simplex method, and the mixing of random walks on P_n.

The Health-Promoting Properties and Clinical Applications of Rice Bran Arabinoxylan Modified with Shiitake Mushroom Enzyme—A Narrative Review

Rice bran arabinoxylan compound (RBAC) is derived from defatted rice bran hydrolyzed with Lentinus edodes mycelial enzyme. It has been marketed as a functional food and a nutraceutical with health-promoting properties. Some research has demonstrated this rice bran derivative to be a potent immunomodulator, which also possesses anti-inflammatory, antioxidant, and anti-angiogenic properties. To date, research on RBAC has predominantly focused on its immunomodulatory action and application as a complementary therapy for cancer. Nonetheless, the clinical applications of RBAC can extend beyond cancer therapy. This article is a narrative review of the research on the potential benefits of RBAC for cancer and other health conditions based on the available literature. RBAC research has shown it to be useful as a complementary treatment for cancer and human immunodeficiency virus infection. It can positively modulate serum glucose, lipid and protein metabolism in diabetic patients. Additionally, RBAC has been shown to ameliorate irritable bowel syndrome and protect against liver injury caused by hepatitis or nonalcoholic fatty liver disease. It can potentially ease symptoms in chronic fatigue syndrome and prevent the common cold. RBAC is safe to consume and has no known side effects at the typical dosage of 2–3 g/day. Nevertheless, further research in both basic studies and human clinical trials are required to investigate the clinical applications, mechanisms, and effects of RBAC.     

Acceleration of the diffusion of aqueous CoCl2 solutions in porous-glass membrane in the presence of alkali metal chlorides

The diffusion coefficients of a 0.1 M aqueous solution of cobalt(II) chloride in a porous-glass membrane with a predominant pore radius of 45 nm in the presence of 0.5–3.0 M of lithium, potassium, and cesium chlorides were determined. Specific features of the influence exerted by the type of accompanying electrolytes on the rate of diffusion transport of CoCl₂ were considered.
