Prevalence of Sarcopenia in Connective Tissue Disease Associated Interstitial Lung Diseases: A Single-Centre Study from India.
Mediterr J Rheumatol
December 2024
Department of Pulmonary Medicine, Kalinga Institute of Medical Sciences, KIIT University, Bhubaneswar, Odisha, India.
Background: Sarcopenia, a progressive loss of skeletal muscle strength and mass, can lead to decreased quality of life, physical disability, and mortality. Early identification of sarcopenia is crucial in limiting morbidity and mortality in connective tissue disease associated interstitial lung diseases (CTDILD) patients.
Objective: The objectives of this study are to determine the prevalence of sarcopenia in CTD-ILD patients and to correlate the severity of sarcopenia with pulmonary function tests, spirometry, and 6-minute walk test (6MWT).
C3AR1 as a target for preeclampsia: from bioinformatics and network pharmacology to experimental validation.
BMC Pregnancy Childbirth

Obstetrics and Gynecology Center, Department of Gynecology, Zhujiang Hospital, Southern Medical University, Guangzhou, Guangdong, 510280, China.
Background: Preeclampsia, characterized by hypertension and proteinuria during pregnancy, poses significant risks to both mother and fetus. The complement system's aberrant activation, notably the C3AR1, is important to the pathogenesis of preeclampsia, although the precise mechanisms are not fully understood.
Materials And Methods: Utilizing the Comparative Toxicogenomics Database (CTD) and Molecular Signatures Database (MSigDB), we identified complement system targets associated with preeclampsia and environmental pollutants.
Uncovering novel KCC2 regulatory motifs through a comprehensive transposon-based mutant library.

Introduction: The neuron-specific K-Cl cotransporter KCC2 maintains low intracellular chloride levels, which are crucial for fast GABAergic and glycinergic neurotransmission. KCC2 also plays a pivotal role in the development of excitatory glutamatergic neurotransmission by promoting dendritic spine maturation. The cytoplasmic C-terminal domain (KCC2-CTD) plays a critical regulatory role in the molecular mechanisms controlling the cotransporter activity through dimerization, phosphorylation, and protein interaction.

Background: Effective management of dual antiplatelet therapy (DAPT) following drug-eluting stent (DES) implantation is crucial for preventing adverse events. Traditional prognostic tools, such as rule-based methods or Cox regression, despite their widespread use and ease, tend to yield moderate predictive accuracy within predetermined timeframes. This study introduces a new contrastive learning-based approach to enhance prediction efficacy over multiple time intervals.

The intricate link between cholesterol metabolism and host immune responses is well recognized, but the specific mechanisms by which cholesterol biosynthesis influences hepatitis B virus (HBV) replication remain unclear. In this study, we show that SREBP2, a key regulator of cholesterol metabolism, inhibits HBV replication by interacting directly with the HBx protein, thereby preventing its nuclear translocation. We also found that inhibiting the ER-to-Golgi transport of the SCAP-SREBP2 complex or blocking SREBP2 maturation significantly enhances HBV suppression.
