Discovery of small molecules against porcine reproductive and respiratory syndrome virus replication by targeting NendoU activity.

Unlabelled: Porcine reproductive and respiratory syndrome (PRRS) remains a major threat to animal health and causes substantial economic losses worldwide. The nonstructural protein 11 (NSP11) of the causative agent, PRRS virus (PRRSV), contains a highly conserved nidoviral uridylate-specific endoribonuclease (NendoU) domain essential for viral replication and immune evasion. Targeting NSP11 offers a novel approach to antiviral intervention.

High-pressure chemistry of functional materials.

Functional materials, possessing specific properties and performing particular functions beyond their mechanical or structural roles, are the foundation of modern matter science including energy, environment, and quantum sciences. The atomic and electronic structures of these materials can be significantly altered by external stimuli such as pressure. High-pressure techniques have been extensively utilized to deepen our understanding of structure-property relationships of materials, while also enabling emergent or enhanced properties.

Aberrant activation of adenine nucleotide translocase 3 promotes progression and chemoresistance in multiple myeloma dependent on PINK1 transport.

Chemoresistance is an important factor in multiple myeloma (MM) relapse and overall survival. However, the mechanism underlying resistance remains unclear. In this study, we identified adenine nucleotide translocase 3 (ANT3) as a novel biomarker and therapeutic target for MM progression and resistance to the proteasome inhibitor bortezomib (BTZ).

Association between ambient temperature and increased total length of hospital stay of patients with cardiopulmonary disease in Hong Kong.

Background: While temperature extremes have been shown to be associated with an increased risk of hospital admissions, evidence of their impact on the length of hospital stay, which may capture the lingering effects of temperature extremes, is scarce.

Objectives: We aimed to evaluate the association between daily variation in ambient temperature and daily variation in daily total length of stay (daily TLOS), a composite measure encompassing the daily count of hospital admissions and their corresponding length of hospital stay among cardiopulmonary patients. Additionally, we quantified the burden of TLOS attributable to non-optimal temperatures among Hong Kong's older adult population.

[The Role of Matrix Metalloproteinase-13 in Multiple Myeloma].

Objective: To investigate the role of matrix metalloproteinase-13 ( ) in the development, diagnosis and prognosis of multiple myeloma (MM).

Methods: Blood samples of 57 MM patients and 45 normal controls were collected, and real-time PCR was performed to detect the mRNA expression level in the study subjects, and the difference of mRNA level between MM patients and normal controls was compared. The correlations of with MM bone disease and its severity, ISS stage, DS stage, and treatment efficacy were analyzed.
