Receptor activator of nuclear factor kappa-B ligand (RANKL) initiates a complex signaling cascade that is crucial for inducing osteoclast differentiation and activation. RANKL-induced signaling has been analyzed in detail, and the involvement of TNF receptor-associated factor 6 (TRAF6), calmodulin-dependent protein kinase (CaMK), NF-κB, mitogen-activated protein kinase (MAPK), activator protein-1 (AP-1), and molecules that contain an immunoreceptor tyrosine-based activation motif (ITAM) has been reported. However, the precise molecular steps that regulate RANKL signaling remain largely unknown.

Article Synopsis
  • Impaired bone quality and increased fracture risk in diabetes may be linked to oxidative stress from high glucose levels affecting osteoblast function.
  • High glucose causes an increase in reactive oxygen species and disrupts the PINK1/Drp1 pathway, which is crucial for mitophagy and late-stage osteoblast differentiation.
  • Enhancing PINK1/Drp1 expression in diabetic mice can improve bone quality and mineral density, indicating it as a possible target for treating diabetic osteoporosis.

Background: Previous studies suggest that it may be inappropriate to determine treatment strategies solely based on the degree of stenosis for patients with intracranial atherosclerotic stenosis (ICAS). In order to better risk stratify patients with ICAS, we developed a novel non-invasive fractional flow (FF) calculation technique based on intracranial angiography (Angio-FF) to assess the hemodynamics for patients with ICAS. This study aims to investigate the difference in FF between symptomatic and asymptomatic patients with ICAS and its potential optimal threshold.

Article Synopsis
  • Benign prostatic hyperplasia (BPH) is a common issue in older males, but how it develops is still not fully understood, prompting research into the role of sphingosine-1-phosphate (S1P) and its receptors (S1PRs) in the prostate.
  • The study found that S1P and its receptors are highly expressed in the prostate, and S1PR1, S1PR2, and S1PR3 are involved in promoting cell growth, muscle contraction, and reducing inflammation via various cellular pathways.
  • Treatment with S1P and specific receptor agonists led to prostate enlargement in rats, while antagonists of S1PR1 and S1PR3 reduced BPH symptoms

Technological advance in industry has complexity, divisibility, systematicity and market selectivity, and companies may generate technological investment expansion and form technological job demand, which may also lead to the occupation of company resources and trigger the replacement of the original jobs. This paper empirically examines the impact of technological advance in industry on the labour employment demand of companies by taking Chinese A-share listed companies as research samples from 2008 to 2022, and finds that: overall technological advance in industry has a suppressive effect on the labour employment demand of companies; The heterogeneity test shows that industrial technological advancement mainly produces inhibitory effects on the labour employment of low-education level employees and production sectors, while it produces incentive effects on the labour employment of high-education level employees and non-production sectors Industrial technological advancement mainly produces job substitution and destructive effects on the labour employment of low-education level employees and production sectors, while it produces incentive effects on the labour employment of high-education level employees and non-production sectors. Mechanism test shows that industrial technological advancement has incentive effects such as technology investment expansion effect and industry chain conduction effect, and also produces inhibitory effects such as enterprise resource occupation effect and employment delay effect.
