Article Synopsis
- - Chronic mild sleep restriction (SR) for 6 weeks does not significantly affect levels of free thyroxine (FT4) or thyroid-stimulating hormone (TSH) in adults, but shows a potential sex difference with TSH reductions noted in women only.
- - The study involved 30 healthy participants (mostly women, with diverse racial/ethnic backgrounds), and measured hormonal levels before and after the AS (adequate sleep) and SR phases through blood samples.
- - Results suggest that while FT4 and fibroblast growth factor-21 (FGF-21) are unchanged, sustained mild sleep restriction might disrupt the regulation of TSH in women, which could be linked to higher cardiometabolic risks compared to

Mammalian genomes contain thousands of genes for long noncoding RNA (lncRNAs), some of which have been shown to affect protein coding gene expression through diverse mechanisms. The lncRNA transcripts are longer than 200 nucleotides and are often capped, spliced, and polyadenylated, but not translated into protein. Nuclear lncRNAs can modify chromatin structure and transcription in trans or cis by interacting with the DNA, forming R-loops, and recruiting regulatory proteins.

With the advancements in conventional treatment modalities such as radiation, chemotherapy, and surgery, as well as the emergence of immunotherapy, the overall cure rate for solid tumor malignancies has experienced a significant increase. However, it is unfortunate that exposure to cancer treatments can have detrimental effects on the function of osteoblasts and osteoclasts, disturbing bone metabolic homeostasis in patients, as well as causing damage to bone marrow cells and other bone tissues. Consequently, certain tumor treatment options may pose a risk for subsequent bone diseases.

Introduction: People with the human immunodeficiency virus (PWH) who were diagnosed long ago are more prone to age-related conditions and comorbidities than the general population. We hypothesized that older PWH have endocrine abnormalities that may influence the patient's health status.
Methods: Mean hormonal values across the thyrotropic, somatotropic, corticotropic, and gonadal axis, and percentage of subjects with abnormal values, were compared between PWH aged ≥50 years (n=30) and people without HIV (n=30) (Over50 cohort).
