High-frequency stimulation (HFS) of the sciatic nerve leads to long-term potentiation (LTP) at C-fiber synapse and long-lasting pain hypersensitivity. The underlying mechanisms, however, are still unclear. In the present study, we investigated the involvement of astrocytes derived l-lactate in the spinal dorsal horn subsequent to glucocorticoid (GC) secretion into the plasma in this process using Sprague-Dawley rats and Aldh1L1-CreER mice of either sex.

The clinical manifestations of AECOPD with and without CAP are confusing. The difference in the survival or readmission rate of AECOPD with or without CAP remains controversial.

Locus ceruleus (LC) neurons, which fire at high rate across wakefulness, are essential for optimal cognitive function. The aim of this study was to investigate whether sirtuin type 3 (SirT3), a redox responses coordinator, plays a role in LTIH-induced neurocognitive impairment.

Compared with soft tissue or bone involvement, thoracic involvement may be associated with a worse prognosis.
Case Presentation: We reported a case of GLA with chylothorax and constrictive pericarditis in a 29-year-old woman.
Rationale: Dyskeratosis congenita (DC) is a rare inherited disease characterized by the classical mucocutaneous triad. Pulmonary fibrosis, bone marrow failure, and solid tumors are the main causes of mortality in DC. Pathogenic variants in TERT, TERC, and DKC1 have been identified in individuals with familial pulmonary fibrosis.

Methods: Two recombinant plasmids with shRNAs targeting the AQP1 gene, AQP1-1-pGenesil and AQP1-2-pGenesil-1 were constructed. Pleural mesothelial cells were obtained from rats, cultured, and randomly divided into 5 groups: blank control group, Lipofectamine 2000 control group, HK negative control group, AQP1-1-pGenesil-1 transfected group, and AQP1-2-pGenesil-1 transfected group.
Objective: The purpose of this study was to investigate whether the expression of AQP-1 on the pleura is altered in a rat model with a tuberculous pleural effusion (TPE) and to study its function.
Methods: A TPE model was established by intrapleural inoculation with 0.03 mg (2 ml) standard tuberculosis bacillus (H(37)Rv).
