Acoustic Analysis of Mandarin-Speaking Transgender Women.

Objectives: This study aims to investigate the speech characteristics and assess the potential risk of voice fatigue and voice disorders in Chinese transgender women (TW).

Methods: A case-control study was conducted involving TW recruited in Shanghai, China. The participants included 15 TW, 20 cisgender men (CISM), and 20 cisgender women (CISW).

Transcriptome analysis of the diseased intervertebral disc tissue in patients with spinal tuberculosis.

Objective: To investigate the differential expression genes (DEGs) in spinal tuberculosis using transcriptomics, with the aim of identifying novel therapeutic targets and prognostic indicators for the clinical management of spinal tuberculosis.

Methods: Patients who visited the Department of Orthopedics at the Second Hospital, Lanzhou University from January 2021 to May 2023 were enrolled. Based on the inclusion and exclusion criteria, there were 5 patients in the test group and 5 patients in the control group.

Characterization of chemical constituents and metabolites in vivo and in vitro after oral administration of Wuteng tablets in rats by UHPLC-Q/TOF-MS.

Waste medicinal plants are widely used in drug production. With the increasing demand for botanical drugs, there is an urgent need to identify new and effective drugs and improve the utilization of medicinal plant resources. Wuteng tablets (WTP) are extracted from the stem of Schisandra chinensis and have a good therapeutic effect on Alzheimer's disease.

Laryngeal Diadochokinesis in the Mandarin Population.

Introduction: This study identifies the most suitable syllable for laryngeal diadochokinesis (LDDK) in Mandarin speakers.

Methods: One hundred and ten Mandarin speakers aged 18-83 years were used in the study. LDDK was assessed using quick repetitions of /ʔe/, /ʔi/, /ʔa/, /he/, /ha/, and /hi/.

α-Mangostin promotes apoptosis of human rheumatoid arthritis fibroblast-like synoviocytes by reactive oxygen species-dependent activation of ERK1/2 mitogen-activated protein kinase.

α-Mangostin (α-M) is a commonly used traditional medicine with various biological and pharmacological activities. Our study aimed to explore the effects and mechanism of α-M in regulating apoptosis of rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS). α-M of 10 to 100 μM was used to treat RA-FLS for 24 hours, followed by measuring cell viability and apoptosis.

MRI analysis of tibial PCL attachment in a large population of adult patients: reference data for anatomic PCL reconstruction.

Background: Consistent reference data used for anatomic posterior cruciate ligament (PCL) reconstruction is not well defined. Quantitative guidelines defining the location of PCL attachment would aid in performing anatomic PCL reconstruction. The purpose was to characterize anatomic parameters of the PCL tibial attachment based on magnetic resonance imaging (MRI) in a large population of adult knees.
