Optimal modes of mind-body exercise for treating chronic non-specific low back pain: Systematic review and network meta-analysis.

Background: There were limited studies that directly compare the outcomes of various mind-body exercise (MBE) therapies on chronic non-specific low back pain (CNLBP).

Objectives: To compare the efficacy of the four most popular MBE modes [Pilates, Yoga, Tai Chi (TC), and Qigong] in clinically CNLBP patients, we conducted a systematic review and network meta-analysis (NMA).

Methods: We searched databases for eligible randomized controlled trials (RCTs) (from origin to July 2022).

Convolutional-de-convolutional neural networks for recognition of surgical workflow.

Computer-assisted surgery (CAS) has occupied an important position in modern surgery, further stimulating the progress of methodology and technology. In recent years, a large number of computer vision-based methods have been widely used in surgical workflow recognition tasks. For training the models, a lot of annotated data are necessary.

Are Mind-Body Exercise Beneficial for Treating Pain, Function, and Quality of Life in Middle-Aged and Old People With Chronic Pain? A Systematic Review and Meta-Analysis.

Background: Aging is a significant risk factor in chronic pain development with extensive disability and greater health care costs. Mind-body exercise (MBE) has been scientifically proven to affect the pain intensity and physical health.

Objectives: To assess the effects of MBE modes (Tai Chi, yoga, and qigong) for treating chronic pain among middle-aged and old people, compared with nonactive and active treatment, as well as function, quality of life, and adverse events.

Two new iridoid glycosides from .

Two new iridoid glycosides, named 3'--benzoyl-dolichocymboside D () and dolichocymboside E (), along with ten known glycosides (), were isolated from the ethanol extract of the whole plants of Moench. The structures of the isolated compounds were elucidated by 1D and 2D NMR and HR-ESI-MS spectra and by comparison with those reported in the literature. This is the first report on compounds and isolated from the family Scrophulariaceae, and compounds were isolated from the genus .

Two new stilbene glucosides and a new benzoic acid derivative from .

Two new stilbene glucosides, -3,5-dihydroxy-4-methoxystilbene 3--D-glucopyranoside (), -3,5-dihydroxy-4-methoxystilbene 3--D-glucopyranoside (), one new benzoic acid derivative, -4-hydroxy-3-hydroxymethyl-2-butenyl benzoate 4--D-glucopyranoside (), and four known compounds () were isolated from L. The structures of these compounds were elucidated on the basis of spectral data. Anti-inflammatory effects of compounds () were evaluated in terms of inhibition on production of NO, TNF-α and IL-6 in LPS-induced RAW 264.

[Relationship between pCO2 and algal biomass in Xiangxi Bay in spring].

Water temperature (WT), pH, HCO3-, dissolved oxygen and the concentration of Chl-a in Xiangxi Bay were measured in spring. The partial pressure of carbon dioxide was calculated by the chemical balance and Henry's Law while CO2 flux by the thin-layer diffusion model. Results showed that pCO2 of surface water in Xiangxi Bay varied from 8.

[Diurnal changes in greenhouse gases at water-air interface of Xiangxi River in autumn and their influencing factors].

With the closed chamber and gas chromatography method, a 24-hour continuous monitoring was carried out to understand the greenhouse gases fluxes across the water-air interface of the Xiangxi River Bay, the Three-Gorges Reservoir in Autumn. Results indicated that the fluxes of CO2, CH4 and N2O across the water-air interface showed an obvious diurnal variation. The absorption and emission process of CH4 showed strong diurnal variation during the experimental period, reaching the highest emission at 1 am, whereas CO2 and N2O were emitted all day.
