Meta-analysis shows dose-response between protein intake and muscle strength

Writing in Sports Medicine – Open, ​the researcher from Meiji and Waseda University added that protein intake must be coupled with resistance training to see a significant improvement in muscle strength. ​ This is said to be the first time that a dose-response was found between protein intake and muscle strength. “​Previous studies have clarified … Read more

What is the impact of cholesterol on SARS-CoV-2 Spike protein-mediated membrane fusion?

In a recent study posted to the bioRxiv* preprint server, researchers assessed the impact of ceramide (CER) and cholesterol (CHOL) on membrane fusion mediated by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein. Study: Cholesterol and ceramide facilitate SARS-CoV-2 Spike protein-mediated membrane fusion. Image Credit: CROCOTHERY/Shutterstock. Background SARS-CoV-2 entrance into host cells is … Read more

BC30 boosts amino acid absorption from plant protein concentrate: Study

Weizmannia coagulansGBI-30, 6086 (BC30, formerly classified as Bacillus coagulans​) has been reported to produce digestive enzymes (proteases) that can digest proteins more efficiently than the endogenous human proteases alone. New data from scientists from Lindenwood University and Increnovo report that combining BC30 supplements with rice and pea protein concentrates led to significantly greater levels of … Read more

Plant-based proteins boost muscle mass in the elderly Chinese population

As most existing data on the association between dietary protein intake and muscle mass come from Western countries, researchers in China have conducted a cross-sectional study to investigate how different amounts and sources of protein consumption affect muscle mass in older Chinese adults. The analysis was based on data from the China Health and Nutrition … Read more

ING2 co-founder on excitement around dileucine

As reported by NutraIngredients-USA​, the company’s dileucine ingredient – ​​branded RAMPS (Rapid Action Muscle Protein Synthesis) – was the subject of a paper published in the Journal of Applied Physiology​, which reported that young men who consumed dileucine had significantly more muscle synthesis than men who ingested only leucine. “When we talk about leucine, this … Read more

Diet therapy with protein and probiotics improves post-COVID sarcopenia treatment

The prolonged immobilisation associated with COVID-19 infection and the restrictions imposed by the pandemic have determined major changes in physical activity and eating habits, with a negative impact on physical performance. Resistance exercise is typically thought to be the strongest protection against sarcopenia (age related progressive loss of muscle mass). Plus protein intake of 1.0–1.3 … Read more

Study finds protein added to carbs aids athletic recovery, but doesn’t boost performance

The new research was published in the Journal of the International Society of Sports Nutrition​. It was the work of a group of researchers associated with Beijing Sport University. The goal of the research was to determine which of the various formulation strategies pursued by energy drink manufacturers (carbohydrates alone or carbohydrates plus protein) helped … Read more

Researchers design a COVID-19 vaccine construct using hybrid SARS-CoV-2 spike protein and nucleocapsid protein peptides

In a recent study posted to the bioRxiv* preprint server, researchers designed a coronavirus disease 2019 (COVID-19) vaccine construct using hybrid SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) spike(S) protein (containing SARS-CoV-2 Delta and Omicron variant mutations) and nucleocapsid (N) protein peptides that confer T lymphocyte-mediated immune protection. Study: De novo design of anti-variant COVID … Read more

Motif-based SARS-CoV-2 protein-human protein interactions as potential antiviral target sites

In a recent study posted to the bioRxiv* preprint server, researchers performed a ProP-PD (proteomic peptide phage display) analysis to identify peptides from intrinsically disordered human (host) proteome regions that bind with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome-encoded folded protein domains (PDs). Study: Identification of motif-based interactions between SARS-CoV-2 protein domains and human … Read more
