Oxidation of Myofibrillar Proteins in Human Heart Failure

Journal of the American College of Cardiology, 2011
We investigated the incidence and contribution of the oxidation/nitrosylation of tropomyosin and actin to the contractile impairment and cardiomyocyte injury occurring in human end-stage heart failure (HF) as compared with nonfailing donor hearts.Although there is growing evidence that augmented intracellular accumulation of reactive oxygen/nitrogen ...

The Age‐Dependent Resident Myonuclear Multi‐Omic Response to an Acute Skeletal Muscle Hypertrophic Stimulus in Mice

Advanced Science, EarlyView.
Resident myonuclei are the molecular “control centers” for large multinuclear muscle fibers. It is presumed that, with aging, these control centers become compromised and contribute to delayed or blunted muscle adaptive potential. This study is a detailed roadmap that exposes how young versus aged myonuclei respond to a hypertrophic loading stimulus ...

Understanding protein–flavor interactions: Factors, characterization techniques, and the effect of processing

Food Biomacromolecules, EarlyView.
Abstract The perception of flavor in a food system depends on its release from the protein matrix. Apart from hydrogen bonding, hydrophobic interactions and van der Waal's forces, the formation of covalent adducts between the flavor and protein highly impacts the release of flavor from the protein matrix.

Pressure-Induced Changes in Myofibrillar Proteins [PDF]

Australian Journal of Biological Sciences, 1979
Natural actomyosin, synthetic actomyosin, myosin and F-actinwere subjected to lactoperoxidasecatalysed iodination with 1251 before and after exposure to a pressure of 150 MNm-2 ? After iodination myosin was split into its subfragments, light and heavy meromyosin, and the actomyosins were separated into their component ...

Chondroitin sulfate restores muscle mass via gut–muscle axis remodeling through sugar–bile acid metabolism reprogramming

iMeta, EarlyView.
The graphical abstract illustrates the molecular mechanism by which chondroitin sulfate (DCS) alleviates glucocorticoid‐induced myopathy through the gut–muscle axis. DCS selectively enriches L. johnsonii Z‐RW, enhancing bshA‐encoded BSH activity to promote bile acid deconjugation and reduce the sugar–bile acid ratio, thereby re‐establishing intestinal ...

Effect of Processing Methods on Protein Oxidation of Beef

Shipin gongye ke-ji, 2022
In order to study the changes of protein oxidation during heat processing, cattle tendon and shoulder were treated at different temperatures (40, 50, 60, 70, 80, 90, 100 ℃, holding time 30 min) and at 70 kPa high pressure for different times (15, 20, 25,

Main effects of ascorbic acid levels and organic acid type on physicochemical properties, microbial populations, texture, and biogenic amine formation in sucuk

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Sucuk is a traditional Turkish dry fermented sausage, the quality and safety of which depend on physicochemical, microbiological, and biochemical changes during fermentation and ripening. Organic acids, their salts, and antioxidants such as ascorbic acid (AA) are widely used in fermented meat products; however, information about ...

Circadian Immunity and Vascular Inflammation in Cardiovascular Disease Chronotherapy Windows: Time for a Re‐Assessment

Med Research, EarlyView.
ABSTRACT Circadian rhythms orchestrate cardiovascular physiology by regulating immune and inflammatory pathways. Disruption of these rhythms profoundly alters vascular homeostasis, thereby promoting the onset and progression of cardiovascular diseases (CVD).

Understanding interactions between four main fishy compounds and grass carp myofibrillar proteins using the SPME-GC–MS, multiple spectroscopy, and molecular docking

Food Chemistry: X
The interaction mechanism between four fishy compounds and myofibrillar proteins of grass crap was explored using solid phase microextraction-gas chromatography–mass spectrometry, multispectroscopy, and molecular docking.

Juvenile hormone‐mediated accelerated post‐flight recovery of ovarian development in Loxostege sticticalis (Lepidoptera: Crambidae)

New Plant Protection, EarlyView.
Flight in female beet webworms (Loxostege sticticalis) promotes an increase in feeding, thereby enhancing abdominal energy reserves. Following flight, the flight muscles undergo accelerated histolysis, and the energy substances undergoing histolysis are redirected to the ovaries. These two processes collectively promote ovarian development.
