Eight females with GV and eight healthy controls completed a running-induced fatigue protocol.

Biomechanical effects of asymmetric backpack shoulder straps on the unilateral flatfoot: a finite element analysis.

This study investigated the biomechanical effects of asymmetric backpack shoulder strap configurations on individuals with unilateral flatfoot (UF) using finite element analysis (FEA). A male subject with UF was recruited, and different shoulder strap settings were simulated to assess their impact on plantar fascia and Achilles tendon stress and strain, as well as on changes in foot arch morphology. The results showed that using equal-length straps on both shoulders resulted in lower stress and strain levels in the plantar fascia and Achilles tendon during walking.

Clofazimine targeting the spike protein and RdRp exhibits highly efficient antiviral activity against porcine epidemic diarrhea virus in vitro.

Porcine epidemic diarrhea virus (PEDV) infection causes acute watery diarrhea in neonatal piglets, leading to substantial economic losses within the pig farming industry. This study demonstrates that clofazimine (CFZ) significantly inhibits PEDV replication in a dose-dependent manner in vitro, with negligible cytotoxicity. Findings from our time-of-addition assays indicate that CFZ effectively disrupts multiple stages of the viral infection cycle.

EFTUD2 is a promising diagnostic and prognostic indicator involved in the tumor immune microenvironment and glycolysis of lung adenocarcinoma.

Gait adaptations in step length and push-off force during walking with functional asymmetry.

Human walking is highly adaptable, allowing individuals to maintain efficiency and stability across diverse conditions. However, how gait adapts to functional asymmetry remains poorly understood.

Serum amyloid P component (SAP), a member of acute response phase protein (APP) family, has been reported to play a crucial role in innate immune response against various microbial pathogens.

The effects of different carbon-fiber plate shapes in shoes on lower limb biomechanics following running-induced fatigue.

Different shapes of carbon-fiber plates (CFPs) are likely to affect lower limb biomechanics, particularly under conditions of running-induced fatigue, and potentially impact runners' performance and risk of injury. However, no studies have yet elucidated the precise effects of CFP shapes on the lower limb biomechanical characteristics subsequent to running-induced fatigue. The purpose of this study was to investigate the effects of different CFP shapes in running shoes on the lower limb biomechanics of runners following running-induced fatigue.
