AI Article Synopsis

  • The study examined 14 patients undergoing intermittent haemodialysis, focusing on their plasma and muscle levels of free- and acetylcarnitine.
  • Results indicated that these patients generally had lower levels of these compounds compared to healthy controls, with more severe deficiency in those on longer-term dialysis.
  • One patient exhibited typical nemaline myopathy, as seen under microscopy, with a notably low muscle free-carnitine concentration, while the majority showed no pathological changes in muscle fibers.

Article Abstract

The present study investigates 14 patients on intermittent haemodialysis. Pre-dialysis blood and muscle samples taken for determining plasma free- and acetylcarnitine levels. The tissue fragments were used for light and electron microscopy studies. Our results support the findings of other investigators that patients on haemodialysis generally display decreased free- and acetylcarnitine levels both in plasma and skeletal muscle when compared with control values. Muscle carnitine deficiency was apparently more severe in the longer-term haemodialysis patients. Moreover, a significant correlation (p less than 0.05) between plasma and muscle free-carnitine values was found. Morphologically no pathological alterations were observed in the muscle fibres in 13 of the patients. Light and electron microscopic studies of the muscle fibre of the 14th patient showed a typical nemaline myopathy with rod bodies in the cytoplasm. The muscle free-carnitine concentration in this patient was among the lowest of the group.

The growing sophistication of tumor molecular profiling has helped to slowly transition oncologic care toward a more personalized approach in different tumor types, including in bladder cancer. The National Comprehensive Cancer Network recommends that all patients with stage IVA and stage IVB urothelial carcinoma have molecular analysis that integrates at least testing to help facilitate the selection of future therapeutic options. Sequencing of tumor-derived tissue is the mainstay to obtain this genomic testing, but as in other cancers, there has been extensive research into the integration of liquid biopsies in longitudinal management.

Optimal adaptation to resistance exercise requires maximal rates of myofibrillar protein synthesis (MyoPS), which can be achieved by postexercise consumption of >20 g of protein or ~2 g of the essential amino acid (EAA) leucine. These nutritional recommendations are based on studies in males. The aim of the present study was to compare the postexercise MyoPS response to nutrition in young females.

Nitrite reverses nitroglycerin tolerance via repletion of a nitrodilator-activated nitric oxide store in vascular smooth muscle cells.

Repeated use of nitroglycerin results in a loss of its vasodilatory efficacy which limits its clinical use for the treatment of angina pectoris. This tolerance phenomenon is a defining characteristic of all compounds classified as nitrodilators, which includes NTG as well as S-nitrosothiols and dinitrosyl iron complexes. These compounds vasodilate via activation of soluble guanylate cyclase, although they do not release requisite amounts of free nitric oxide (NO) and some do not even cross the plasma membrane.

Objectives: This study aimed to evaluate the effects of pre-conditioning exercise on body lipid metabolism, leptin secretion, and the downstream pathways at the early stage of type 2 diabetes mellitus (T2DM).

Materials And Methods: The T2DM model was established using an 8-week high-sugar, high-fat diet combined. The T2DM model was established using an 8-week high-sugar, high-fat diet combined with streptozocin (STZ) injection.

Introduction: This systematic review/meta-analysis evaluated the impact of sarcopenia in patients with cirrhosis before liver transplantation (LT) on outcomes after LT.

Methods: A systematic search was conducted in six medical databases until February 2022. The primary outcome was overall mortality after LT, while several secondary outcomes including liver graft survival and rejection, the need for transfusions, the length of the intensive care unit (ICU) and hospital stay, and surgical complications were evaluated.
