Abstract:

Introduction: Post-dilution online hemodiafiltration is the most efficient extracorporeal depurative treatment of CKD. Recently a new type of membrane has been developed, with a higher cut-off point also called a medium cut-off point, which has the capacity to eliminate higher molecular weight molecules in hemodialysis. The hemodialysis performed with these membranes has been called “Expanded Hemodialysis”. Objective: Compare the purifying efficacy of medium and high molecular weight molecules in patients dialyzed with high-flux hemodialysis, VitaPES 210HF, and with patients treated with expan

Abstract:

Medium chain triglycerides are considered to be readily absorbed intact in the absence of pancreatic lipase, unlike long chain triglycerides. Commercial medium chain triglyceride oils comprise various medium chain fatty acids from 6 to 12 carbons in length resulting in triglyceride molecules of different sizes and molecular weights. The effect of molecular weight and hence fatty acid chain length on the efficiency of intact medium chain triglyceride absorption is unknown. Therefore, this study measured, using a single-pass marker perfusion technique, intestinal jejunum absorption of five mediu

Chronic kidney disease leads to the accumulation of a wide range of uremic toxins. Negative effects of uremic toxins are most likely due to the combined effects of many uremic solutes, including small molecules, middle molecules, and soluble protein-linked substances.

In the present study, hydrolysates of mackerel and herring were produced and utilized as sources of peptones in the formulation of new bacterial culture media. The molecular weight distribution analysis showed that molecules present in the hydrolysates were lower than 1300 Da for herring, and lower than 930 Da for mackerel.

Abstract:

The search for new forms of already known drug compounds is an urgent problem of high relevance as more potent drugs with fewer side effects are needed. The trifluoromethyl group in flufenamic acid renders its chemical structure differently from other fenamates. This modification is responsible for a large number of conformational polymorphs. Therefore, flufenamic acid is a promising structural modification of well-known drug molecules. An effective approach in this field is micronization, employing “green” supercritical fluid technologies. This research raises some key questions to be answere

Abstract:

The presence of toxins is believed to be a major factor in the development of uremia in patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD). Uremic toxins have been divided into 3 groups: small substances dissolved in water, medium molecules: peptides and low molecular weight proteins, and protein-bound toxins. One of the earliest known toxins is urea, the concentration of which was considered negligible in CKD patients. However, subsequent studies have shown that it can lead to increased production of reactive oxygen species (ROS), and induce insulin resistance in vi

The purpose of blood purification therapy is to remove uremic toxins, and middle molecules (MMs) are a specific target. An MM is defined as a solute that passes through the glomerulus with a molecular weight in the range of 0.5–58 kDa, and new classifications of “small-middle 0.5–15 kDa,” “medium-middle 15–25 kDa,” and “large-middle 25–58 kDa” were proposed. In Japan, the removal of α1-microglobulin (αMG) in the large-middle range has been the focus, but a new theory of removal has been developed, emphasizing the antioxidant effect of αMG as a physiological function.

The T2612C transition predicts substitution of cysteine by arginine at amino acid position 788 (C788R), and the T3923G transversion predicts substitution of cysteine by glycine at position 1225 (C1225G) of pre-pro-vWF.
