Dual-energy X-ray absorptiometry for the simultaneous determination of Density and Moisture Content in Porous Structural Materials

open access: yes, 1999
The paper describes the dual-energy x-ray equipment, which consists of a x-ray source, filters and a detector. The x-ray beam can be moved automatically in two dimensions relative to a fixed specimen.

Bone biology in aging periodontal and peri‐implant tissues

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Periodontal disease is an age‐related chronic inflammatory condition leading to tooth loss. Dental implants are an option for replacement of lost teeth in older adults. However, age‐related changes to alveolar bone may have pathological implications for its role in supporting the dentition and dental implants.

On X-ray Source for Dual Wave Absorptiometry [PDF]

open access: yes, 2019
A new method for the formation of a dual X-ray source spectrum for the method of analyzing multiphase fluid flow based on wave dispersive X-ray absorptiometry using crystalline monochromators is proposed.

Effect of artificial gravity on calcaneal bone marrow adipose tissue and mineral content in female and male participants in 60 days of bed rest

open access: yesExperimental Physiology, EarlyView.
Abstract Modulation of bone marrow adipose tissue (BMAT) with prolonged inactivity was reported in haemopoietic but not in non‐haemopoietic bones. This prospective randomized controlled trial submitted 16 men and 8 women to 60 days of 6° head‐down‐tilt bed rest.

Molecular pathophysiology of chronic kidney disease–mineral and bone disorder: Focus on the fibroblast growth factor 23–Klotho axis and bone turnover dynamics

open access: yesExperimental Physiology, EarlyView.
Abstract Chronic kidney disease–mineral and bone disorder (CKD‐MBD) is a major complication of chronic kidney disease (CKD), characterized by disruptions in mineral metabolism, abnormal bone turnover and vascular calcification, which collectively increase the risk of fractures and cardiovascular disease.

Prevalence of sarcopenia and sarcopenic obesity in Korean adults: The Korean Sarcopenic Obesity Study (KSOS)

open access: yes, 2009
*Context:* Sarcopenic obesity (SO), a combination of excess weight and reduced muscle mass and/or strength, is suggested to be associated with an increased risk of adverse health outcomes.

Seven days of mixed‐method heat acclimation improved markers of cardiovascular and fluid‐regulatory strain during exercise‐heat stress

open access: yesExperimental Physiology, EarlyView.
Abstract A mixed‐method heat acclimation (HA) protocol may optimise performance by supporting the training taper while promoting thermal adaptation; however, the impact on cardiovascular and fluid‐regulatory adjustments to protect health is unknown. Therefore, we examined the effects of a mixed‐method heat protocol on physiological responses, including
