Effectiveness of bisphosphonates on bone mineral density in osteopenic postmenopausal women: A systematic review and network meta-analysis of randomized controlled trials.

Background: Various bisphosphonate agents have been proven to be effective in preventing bone loss and fracture in osteopenic postmenopausal women. This study was designed to compare the effectiveness of various BPs on preventing the loss of bone mineral density (BMD) for postmenopausal women with osteopenia.

Methods: PubMed, EMBASE, and Cochrane Central Register of Controlled Trials were screened up to identify randomized controlled trails comparing effectiveness of BPs or placebo on the BMD of postmenopausal women with osteopenia.

Nanosphere [Ag(SR)]: coordination polymers of Ag with a combination of hydrophilic and hydrophobic thiols.

We propose to create nanospheres in aqueous solutions from coordination polymers of Ag+ with a combination of a hydrophilic and a hydrophobic thiol, of diameter ca. 2.7 nm in the case of using cysteine and n-butanethiol.

Chiral Recognition by Flexible Coordination Polymers of Ag with a Cysteine-Based Chiral Thiol Ligand That Bears a Binding Site.

We report a new scheme for chiral recognition using coordination polymers of Ag with a chiral thiol ligand that contains a binding group. -Benzoyl-l-cysteine ethyl ester equipped with a boronic acid group at the para position of the phenyl ring forms coordination polymers with Ag in alkaline aqueous solutions that exhibit excellent selectivity toward a d-glucose enantiomer over l-glucose, while the coordination polymers from the d-cysteine-based thiol ligand are specific for l-glucose. It is assumed that a conformation change occurs upon interaction of a saccharide molecule with the polymeric chain receptor, for which the next binding is promoted, leading to the highly effective chiral recognition, despite the flexible nature of the polymeric receptor.

Effect of comprehensive rehabilitation nursing intervention on hemiplegia patients in sequela stage of stroke.

Objective: To explore the clinical effect of comprehensive rehabilitation nursing intervention on hemiplegia patients in the sequela stage of stroke.

Methods: Patients with knee reflex after stroke were divided into the treatment group and the control group. Patients in the control group received Activities of Daily Living (ADL) training.

Sensing Active Heparin by Counting Aggregated Quantum Dots at Single-Particle Level.

Developing highly sensitive and highly selective assays for monitoring heparin levels in blood is required during and after surgery. In previous studies, electrostatic interactions are exploited to recognize heparin and changes in light signal intensity are used to sense heparin. In the present study, we developed a quantum dot (QD) aggregation-based detection strategy to quantify heparin.

Counting quantum dot aggregates for the detection of biotinylated proteins.

We develop a method to quantify the quantum dots (QDs) in QD aggregates in aqueous solution by recording the entire process of blue shifting and photobleaching under continuous illumination and utilize this method to detect the biotinylated proteins based on counting the degree of aggregation (DOA).

Investigating the photostability of quantum dots at the single-molecule level.

Quantum dots (QDs) have shown great potential to provide spatial, temporal, and structural information for biological systems. However, blinking, photobleaching, and spectral blueshift are adverse effects on their practical applications in biomedical research. An investigation of the effects of six reducing agents including cysteine (Cys), 1,4-dithiothreitol (DTT), ethyl gallate (EG), L-glutathione (GSH), mercaptoacetic acid (MAA), and thiourea (TU) on the photostability of single QDs was studied.
