AI Article Synopsis
- This study investigates how a deficiency in selenium affects mRNA levels of 25 different selenoproteins in the adipose tissues of chickens.
- One hundred and fifty 1-day-old chickens were divided into two groups, with one group receiving a low-selenium diet and the other a control diet.
- Results indicated that the chickens on the low-selenium diet had significantly lower expression of the selenoprotein mRNAs, which decreased further over time.
Article Abstract
This study describes the effects of selenium (Se) deficiency on the messenger ribonucleic acid (mRNA) expression of 25 selenoproteins (Sels) (including glutathione peroxidases (GPx1-GPx4), thioredoxin reductases (TrxR1-TrxR3), iodothyronine deiodinases (ID1-ID3), selenophosphate synthetase 2 (SPS2), 15-kDa Sel (Sel15), SelH, SelI, SelK, SelM, Sepn1, SelO, Sepx, Selpb, SelS, SelT, SelW, Sepp1, and SelU in the adipose tissues (subcutaneous adipose, visceral adipose, and articular adipose) of chickens. One hundred and fifty 1-day-old chickens were randomly assigned to two groups of 75 each and were fed a low-Se diet (0.032 mg/kg Se) or a control diet (0.282 mg/kg Se). The expression levels of 25 Sel mRNAs were determined on days 35, 45, and 55 from three parts (subcutaneous adipose, visceral adipose, and articular adipose) of the chicken adipose tissues. The results showed that the expression levels of the 25 Sel mRNAs were significantly lower (P < 0.05) in the low-selenium group than in the control group. In addition, the Sel mRNA expression levels in the three adipose tissues were observed to decrease in a time-dependent manner with increasing feeding time.

Skeletal muscle oxidative capacity related to intramyocellular lipid in young but not in older individuals.
Appl Physiol Nutr Metab
January 2025
Nagoya University, Graduate School of Education and Human Development, Nagoya, Japan.
Skeletal muscles contain lipids inside and outside cells, namely intramyocellular lipids (IMCL) and extramyocellular lipids (EMCL), respectively; lipids have also been found to be interspersed between these muscles as adipose tissue, namely intermuscular adipose tissue (IMAT). Metabolized IMCL has been recognized as an important substrate for energy production and their metabolism is determined by the muscle oxidative capacity. Therefore, it has been speculated that muscle oxidative capacity is related to muscle lipid content.

The present study examined factors associated with trunk skeletal muscle thickness (MT, an index for the amount of skeletal muscle) and echo intensity (EI, an index for the content of non-contractile tissue, such as intramuscular adipose tissue) in young Japanese men and women in consideration of habitual dietary intake. Healthy men (n = 26) and women (n = 24) aged 20 to 26 were enrolled. Trunk MT and EI were evaluated using ultrasound imaging at the height of the 3rd lumbar vertebra.

Changes in the lipid and carbohydrate metabolism, adipokines, and growth factors during the development of metabolic disorders were studied in three mouse models: C57BL/6 (alimentary obesity), db/db (leptin-resistant obesity), and NOD (diabetes mellitus) lines. In the group of alimentary obesity, moderate fatty infiltration of the liver and hypertrophy of the adipose tissue, hyperglycemia, and increased concentrations of adiponectin, transforming growth factor β1 (TGF-β1), leptin, and cholesterol were detected. In the group of leptin-resistant obesity, multiple pathological changes in tissues, severe hyperglycemia and hyperleptinemia, hyperinsulinemia, and reduced concentrations of triglycerides, adiponectin, myostatin, and TGF-β1 were detected.

This study tested whether combined ceftriaxone and adipose-derived mesenchymal stem cells (ADMSCs) would defend the spinal cord against acute spinal infection (ASI) in rodent. Adult-Male-SD rats were grouped into groups 1 (SC)/2 (ASI)/3 (ASI + ceftriaxone from days 2 to 28 after ASI induction)/4 (ASI + allogenic ADMSCs from day 2 for a total of 3 doses/3 consecutive intervals by intravenous injection)/5 (ASI + combined ceftriaxone and ADMSC) and spinal cord tissues were harvested by day 28. Circulatory levels of TNF-α/IL-6 at days 7 and 28, and these two parameters in spinal fluid at day 28 were lowest in group 1, highest in group 2, significantly lower in group 5 than in groups 3/4, and significantly lower in group 3 than in group 4 (all p < 0.

Background: Immune-mediated inflammatory diseases (IMIDs) are a group of chronic conditions characterized by dysregulated immune responses and persistent inflammation. Rheumatoid arthritis (RA), spondyloarthritis (SpA), and ulcerative colitis (UC) exemplify prominent IMIDs, each presenting unique challenges for their management, that impact patient's quality of life (QoL). Obesity, marked by persistent low-grade inflammation, influences the progression, response to treatment, and clinical management of patients with RA, SpA, and UC.
