Belt electrode-skeletal muscle electrical stimulation (B-SES) involves the use of belt-shaped electrodes to contract multiple muscle groups simultaneously. Twitch contractions have been demonstrated to protect against denervation-induced muscle atrophy in rats, possibly through mitochondrial biosynthesis. This study examined whether inducing tetanus contractions with B-SES suppresses muscle atrophy and identified the underlying molecular mechanisms.

Epidemiological studies have shown that the consumption of green tea has beneficial effects against cancer. Basic studies have provided evidence that epigallocatechin gallate (EGCG) is a major contributor to these effects. Matrix metalloproteinases (MMPs) are zinc-dependent metalloproteinases with the ability to degrade the extracellular matrix proteins and are involved in various diseases including cancer in which MMPs have a critical role in invasion and metastasis.

Growing evidence has been accumulated to show the anticancer effects of daily consumption of polyphenols. These dietary polyphenols include chlorogenic acid, curcumin, epigallocatechin-3--gallate, genistein, quercetin, and resveratrol. These polyphenols have similar chemical and biological properties in that they can act as antioxidants and exert the anticancer effects via cell signaling pathways involving their reactive oxygen species (ROS)-scavenging activity.

Article Synopsis
  • Belt electrode skeletal muscle electrical stimulation (B-SES) can effectively contract multiple muscle groups and may help prevent muscle atrophy due to denervation.
  • A study using a new ankle stimulation system showed that low-frequency electrical stimulation (7-8 Hz for 30 minutes daily) partially protected against muscle loss in rats compared to control and denervation-only groups.
  • Findings indicated that B-SES improved mitochondrial function and reduced muscle proteolytic activities, highlighting its potential to maintain muscle health after nerve damage.

Nivolumab, an immune checkpoint inhibitor (ICI), is now used to treat many advanced cancers, including non-small cell lung cancer (NSCLC) and renal cancer. Immune-related adverse events are characteristic side effects of ICIs. Among them, fulminant type 1 diabetes mellitus is an infrequent but potentially life-threatening and clinically significant concern.
