A label-free ThT-assisted fluorescence detection strategy of alkaline phosphatase activity based on MnO nanosheets.

Alkaline phosphatase (ALP) is a metalloenzyme, the level of which is clinically significant as an abnormality of ALP activity results in several diseases. In the present study, we introduced a MnO nanosheet-based assay for ALP detection employing the adsorption and reduction characteristics of G-rich DNA probes and ascorbic acid (AA), respectively. Ascorbic acid 2-phosphate (AAP) was utilized to act as a substrate for ALP which hydrolyzes AAP generating AA.

Oral delivery of proteins and peptides: Challenges, status quo and future perspectives.

Proteins and peptides (PPs) have gradually become more attractive therapeutic molecules than small molecular drugs due to their high selectivity and efficacy, but fewer side effects. Owing to the poor stability and limited permeability through gastrointestinal (GI) tract and epithelia, the therapeutic PPs are usually administered by parenteral route. Given the big demand for oral administration in clinical use, a variety of researches focused on developing new technologies to overcome GI barriers of PPs, such as enteric coating, enzyme inhibitors, permeation enhancers, nanoparticles, as well as intestinal microdevices.

Exercise intervention in the management of urinary incontinence in older women in villages in Bangladesh: a cluster randomised trial.

Background: Group exercise-based programmes for urinary incontinence appear to be promising low-cost interventions for women in developing countries, but no evidence exists to support whether they could be implemented or effective in such populations. We aimed to evaluate whether a group intervention that comprised pelvic floor muscle training, mobility exercises, and bladder education would be more effective than education alone, and report changes between villages (ie, clusters) rather than between individual participants.

Methods: In this cluster randomised trial, we recruited women from 16 pairs of villages in Bangladesh, with each pair comprising similar villages from the same sub-district.
