Single-photon imaging is an emerging technology in sensing that is capable of imaging and identifying remote objects under extreme conditions. However, it faces several challenges, such as low resolution and high noise, to do the task of object detection. In this work, we propose an enhanced You Only Look Once network to identify and localize objects within images generated by single-photon sensing.

This study aimed to explore the correlation between serum ferritin and additional biomarkers associated with iron metabolism, as well as their connection to muscle atrophy and frailty in the community-dwelling middle-aged and elderly population. The study included 110 middle-aged and elderly participants. Participants were categorized into an iron accumulation group (31 cases) and a normal iron group (79 cases) based on the standard ferritin values for men and women.

The objective of this study is to employ Mendelian randomization techniques to clarify the association between serum iron status and sarcopenia. We conducted a bi-directional Mendelian randomization (MR) analysis to investigate the potential causal relationship between iron status and sarcopenia.

The main purpose of this study is to evaluate the relationship between outpatients' different internal factors (sociodemographic and psychological characteristics) and different external factors (provider characteristics) regarding their choice of hospital.
Methods: The data obtained via questionnaire was analyzed with a linear regression model to verify the relationship between outpatients' internal and external factors.
Osteopetrosis is a rare congenital bone disorder, characterized by systemic osteosclerosis due to a deficiency of or functional defect in osteoclasts. Autosomal dominant osteopetrosis (ADOP) is the most common form with a late onset, a stable condition, relatively few symptoms and a good prognosis. Few studies to date have reported successful total hip arthroplasty (THA) in patients with ADOP and its operative difficulties.

The pathogenesis of sarcopenia is complex, and many factors are involved in its development and progression. Sarcopenia might be associated with iron accumulation given that (1) age-related iron accumulation was found in the skeletal muscle, (2) excess iron could cause skeletal muscle damage or atrophy, and (3) patients with sarcopenia showed higher levels of serum ferritin.

However, in human subjects, a direct molecular relationship has not been identified between angiogenesis and agents that promote bone disease or factors related to age. Osteopenia is a condition in which bone mineral density is lower than normal, and it represents a sign of normal aging.

Various irrigation solutions are currently being used; however, a comprehensive study on their efficacy is lacking. In the present study, a comparison of the effects of normal saline, iodophor and hydrogen peroxide as the irrigation solutions for debridement of open femur fractures in rat models was conducted.

This meta-analysis, which pooled results from 10 prospective cohort studies, was performed to derive a more precise estimation between cigarette smoking and the risk of hip fracture in women.
Materials And Methods: Pubmed, Cochrane Central Register of Controlled Trials and ISI Web of Science were systematically searched to identify relevant studies.

Objective: To explore the antagonistic effect of estrogen on iron-induced bone resorption and the role of oxidative stress.
Methods: In vivo, 8-week-old female imprinting control region mice were randomly divided into 3 groups of ferritin (F), ovariectomy (OVX) and F+OVX. Intervention was made by ferric ammonium citrate (FAC) and OVX.
Iron metabolism is tightly regulated in osteoblasts, and ferroportin 1 (FPN1) is the only identified iron exporter in mammals to date. In the present study, the regulation of FNP1 in human osteoblasts was investigated following various iron treatments. The human osteoblast cell line hFOB 1.

Because iron overload may be one of the causes of osteoporosis, hepcidin may have therapeutic potential for osteoporosis patients. However, the effects of hepcidin on bone metabolism are not fully clear.

Iron overload has recently been connected with bone mineral density in osteoporosis. However, to date, the effect of iron overload on osteoblasts remains poorly understood. The purpose of this study is to examine osteoblast biological activity under iron overload.
View Article and Find Full Text PDFBone metabolism has a close relationship with iron homeostasis. To examine the effects of iron excess and iron deficiency on the biological activities of osteoblast in vitro, human osteoblast cells (hFOB1.19) were incubated in a medium supplemented with 0-200 μmol/L ferric ammonium citrate and 0-20 μmol/L deferoxamine.
