Many clinical studies have shown that osteoporosis is associated with atherosclerosis and cardiovascular death. Although both high plasma levels of low density lipoprotein cholesterol (LDL-C) (HDL-C) are known to be risk factors for atherosclerosis, it unclear whether such lipid derangements also the pathogenesis osteoporosis. In this study, we evaluated relationships between total C, LDL-C, HDL-C, or triglyceride (TG) versus bone mineral (BMD) at lumbar spine, femoral neck, radius, body as...

Peripheral quantitative computed tomography (pQCT) is useful for evaluating volumetric bone mineral density (vBMD) as well (BMD) of cortical and trabecular bones separately. Although PTH affects differently, the effects endogenous on vBMD geometry have not previously been examined with pQCT. We, therefore, investigated an excess a deficiency by employing dual-energy x-ray absorptiometry pQCT in 36 female patients primary hyperparathyroidism (hyper), nine idiopathic or postoperative...

Leaf endospheres harbor diverse bacterial communities, comprising generalists and specialists, that profoundly affect ecosystem functions. However, the ecological dynamics of generalist specialist leaf-endophytic bacteria their responses to climate change remain poorly understood. We investigated diversity environmental within leaf endosphere mangroves across China. Our findings show a predominance specialists in mangrove endosphere. Temperature is key factor driving community dissimilarity...

Soil fungi in mangroves are diverse and crucial for organic matter decomposition element cycling. However, the drivers influencing network complexity stability of fungal communities across different mangrove soil habitats remain unclear. This study investigated main factors driving composition, diversity, complexity, clay loam sandy soils ecosystems. Results showed that Dothideomycetes Sordariomycetes dominated soils, respectively. Sandy exhibited higher alpha diversity than loam. Beta...

Cu-Ni-Si alloys are widely used due to their good electrical conductivities in combination with high strength and hardness. In the present work, minor-alloying M = (Cr, Fe, Mo, Zr) was conducted for objective of further improving hardness while maintaining conductivity level. A cluster-plus-glue-atom model introduced design compositions M-alloyed alloys, which an ideal composition formula [(Ni,Si,M)-Cu12]Cu3 (molar proportion) proposed. To guarantee complete precipitation solute elements...

Although many reports have demonstrated the sustained increase in bone mineral density (BMD) at trabecular sites primary hyperparathyroidism (pHPT) after parathyroidectomy (PTX), there been no data available on BMD changes over long-term pHPT patients with and without PTX Japanese population. The present study was designed to investigate both cortical or PTX.The subjects were 97 who had followed up Kobe University Hospital for least 1 year 6 years PTX. recommended all whose pathological...

Methods for the generation of indoor geographic information system (GIS) models based on building modelling (BIM) can promote analysis and application GIS, avoiding complexity traditional space collection. The adjacency relations (i.e., attribute IndoorGML) play a vital role in adjacent query GIS applications obtaining neighbors or affected spaces cellular building). However, current methods ignore important feature, which considerably limits spatial ability GIS. Therefore, we developed...
