To study the effects of whole-body vibration exercises on mobility function, balance and general health status, its feasibility as an intervention in frail elderly patients.Pilot randomized controlled trial.Forty-four older persons (85.27 ± 3.63 years) meeting Fried Frailty Criteria.All eligible subjects were randomly assigned to experimental group, who received a exercise alone (vibration amplitude: 1-3 mm; frequency: 6-26 Hz; 4-5 bouts × 60 seconds; 3-5 times weekly), or control usual care...
Understanding post-fire vegetation recovery dynamics is crucial for damage assessment and planning, yet spatiotemporal patterns in complex plateau environments remain poorly understood. This study addresses this gap by focusing on Yunnan Province, a mountainous region with high fire incidence. We developed an innovative approach combining differenced Normalized Burn Ratio (dNBR) visual interpretation Google Earth Engine (GEE) to generate high-quality training samples from Landsat 5 TM/7...
Forest fine fuels are a crucial component of surface and play key role in igniting forest fires. However, despite nearly 20 years long-term prescribed burning management on Zhaobi Mountain Xinping County, Yunnan Province, China, there remains lack specific quantification regarding the effectiveness fuel Pinus yunnanensis forests. In this study, 10 m × sample plots were established following one year growth after burning. The placed (PB) area an unburned control (UB) area. We utilized...
Two previously undescribed sesquiterpenoids, including one germacrane sesquiterpenoid (1) and guaiane (2), were isolated characterized from the branches leaves of Michelia alba DC., along with eleven known sesquiterpenoids (3‐13). The structures new compounds elucidated using comprehensive high‐resolution electrospray ionization mass spectroscopy, infrared, ultraviolet, nuclear magnetic resonance analyses, absolute configurations determined through single‐crystal X‐ray diffraction analysis...
A fluorescence probe for detecting nitric oxide based on dihydropyridine showed high selectivity and sensitivity as well cell imaging ability.
Introduction Positioning studies on prescribed burning in Pinus yunnanensis forests have been conducted for several years, focusing the effects of fire composition and structure, growth, regeneration, relative bark thickness, density understory oak species forests. Methods The study was Zhaobi Mountain, Yi-Dai Autonomous County Xinping, Yuxi City, Yunnan Province. In burn after restoration full 1 year area did not implement were set up 10 m × sample plots 30 pairs comparisons, all trees...
The Altai Mountains, located in the northwesternmost part of China, have a harsh climate and little human activity, making it an excellent location to study forest ecology undisturbed by interference. is frequently struck lightning experiences long-term natural fire disturbances, leading evolution unique adaptation traits major conifer species. To explore role disturbances Mountain ecosystem, we conducted on Larix sibirica, Pinus Picea obovata, Abies reconstructed history area over past 100...
The present study investigated the effects of nesfatin-1 on gastric distension (GD)-responsive neurons via an interaction with corticotropin-releasing factor (CRF) receptor signaling in ventromedial hypothalamic nucleus (VMH), and potential regulation these by hippocampal projections to VMH. Extracellular single-unit discharges were recorded VHM following administration nesfatin-1. projection nerve fibers expression assessed retrograde tracing fluoro-immunohistochemical staining,...
We analyzed hemoglobin (Hb) levels and degree of anemia in relation to genotype patients with H (Hb H) disease, thereby providing a scientific basis for the prevention treatment Hb disease Guangxi region China. analysis was conducted 615 using high performance liquid chromatography. Seven α-thalassemia 17 β-thalassemia genotypes commonly found Chinese population were detected by Gap-polymerase chain reaction reverse dot hybridization. Multiple ligation-dependent probe amplification...
Warming-induced drought stress and El Nino-associated summer precipitation failure are responsible for increased forest fire intensities of tropical temperate forests in Asia Australia. However, both effects unclear boreal forests, the largest biome carbon stock over land. Here, we combined frequency, burned area, climate data Altai southmost extension Siberia’s into China, explored their link with Nino–Southern Oscillation (ENSO). Surprisingly, severity occurrence showed significant (p <...
Prescribed burning is a widely used fuel management employed technique to mitigate the risk of forest fires. The Pinus yunnanensis Franch. forest, which frequently prone fires in southwestern China, serves as prime example for investigating effects prescribed on flammability surface dead fuel. This research aims establish scientific foundation managing forests, well fire prevention and control strategies. Field data was collected from P. forests located central Yunnan Province 2021 2022....
795 nm oxide-confined distributed feedback (DFB) lasers have been developed. The structure is used to realize lateral optical and current confinement, the first order surface gratings offer frequency selectivity for single longitudinal mode operation. fabricated 200-um-long devices exhibited a low-threshold of ∼4.8 mA, 3-dB modulation bandwidth ∼5.8 GHz maintained stable operation around with side suppression ratio (SMSR) as high ∼40 dB. simple compact laser greatly reduces difficulty device...
Histone deacetylase (HDAC) inhibitors have been demonstrated to be effective anti-cancer candidates against aggressive malignancies.In previous study, a novel hydroxamic acid derivate, CTS203 cyclo(-l-Asu(NHOH)-l-A3mc6c-l-Phe-d-Pro-), promising HDAC inhibitory activity.Herein, more biological evaluations including cell viability, cycle distribution, cellular morphology, expression quantification as well protein-protein interactions were measured investigate its cytotoxic...
The basis for individual variation in gastroduodenal vulnerability to NSAIDs is not well understood.
Abstract Background The Pinus yunnanensis forest in southwestern China is a unique and significant vegetation type. However, it susceptible to frequent fires. To mitigate the risk of hazardous fires, prescribed burning has often been employed these forests. Nevertheless, important consider potential impact on structure plant communities species diversity investigate specific changes community characteristics caused by burning, study was conducted located Zhaobi Hill, Xinping county. Results...
