Unesterified cholesterol accumulation in the late endosomal/lysosomal (LE/LY) compartment is cellular hallmark of Niemann-Pick C (NPC) disease, caused by defects genes encoding NPC1 or NPC2. We previously reported dramatic stimulation NPC2 transport rates to and from model membranes LE/LY phospholipid lysobisphosphatidic acid (LBPA). It had been shown that enrichment NPC1-deficient cells with LBPA results clearance. Here we demonstrate human NPC2-deficient cells, either directly via its...

To improve the phenomenon of exercise-induced fatigue that often occurs during horse racing, we previously studied improvement in exercise tolerance by acupoint catgut embedding preconditioning an rat model. We found pretreatment effectively improved animal tolerance. Here, combining transcriptomics and metabolomics, aimed to explore underlying mechanisms this improvement. used blood biochemical detection combined with ELISA detect triglyceride (TG), total cholesterol (TC), lactate...

Patients with chronic lymphocytic leukemia (CLL) have reduced seroconversion rates and lower binding antibody (Ab) neutralizing (NAb) titers than healthy individuals following Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) mRNA vaccination. Here, we dissected vaccine-mediated humoral cellular responses to understand the mechanisms underlying CLL-induced immune dysfunction.

Abstract Knowledge about neighborhood characteristics that predict disease burden can be used to guide equity-based public health interventions or targeted social services. We a case-control design examine the association between area-level vulnerability and severe COVID-19 using electronic records (EHR) from regional information hub in greater Philadelphia region. Severe cases ( n = 15,464 unique patients) were defined as those with an inpatient admission diagnosis of 2020. Controls 78,600;...

Background The majority of elderly individuals prefer to spend their final days in the Intensive Care Unit (ICU). ICU nurses are key providers hospice care, and attitudes toward death influence quality end-of-life nursing. Positive psychology emphasizes promoting positive death. A sense meaning life resilience critical aspects psychology, which essential for shaping nurses’ Objective This study aims investigate whether a indirectly affects through mediation resilience.

Niemann Pick Type C (NPC) disease is a lysosomal storage disorder characterized by cholesterol accumulation in the late endosome/lysosome (LE/LY) caused genetic defects either NPC1 or NPC2 proteins. Wild type (WT) 16 kDa soluble protein that binds with 1:1 stoichiometry. We previously showed interacts directly membranes to transport cholesterol; structure‐function analysis has shown several regions of surface are involved transport, suggesting can not only interact various orientations, but...

Chronic lymphocytic leukemia (CLL) patients have lower seroconversion rates and antibody titers following SARS-CoV-2 vaccination, but the reasons for this diminished response are poorly understood. Here, we studied humoral cellular responses in 95 CLL 30 healthy controls after two BNT162b2 or mRNA-2173 mRNA immunizations. We found that 42% of vaccinees developed SARS-CoV-2-specific binding neutralizing antibodies (NAbs), while 32% had no response. Interestingly, 26% were seropositive,...
