Statin use and fall risk in adults: a cross-sectional survey and mendelian randomization analysis.

Background And Objective: The issue of falls poses a significant threat to the health of the elderly population. Although statins can cause myopathy, which implies that they may cause balance problems and increase the risk of falling, this has not been tested. Our objective was to assess whether the use of statins is linked to a higher risk of falls.

Bioactive monoterpenoids and acetophenones from the aerial parts of Eupatorium fortunei.

Thirty-nine thymol and acetophenone derivatives, including eight pairs of enantiomers, were isolated from the aerial parts of Eupatorium fortunei. Their structures were assigned by detailed analyses of spectroscopic data and NMR calculations based on density functional theory, with 18 ones (1a/1b-14) being previously undescribed compounds. While the absolute configurations of 1a/1b, 2a/2b, 4, 6a/6b, 7, 11a/11b and 15a/15b-18a/18b were established by calculations of electronic circular dichroism data, that of 14 was determined by modified Mosher's method.

Chemical constituents from Eupatorium fortunei and their anti-inflammatory evaluation by in silico and experimental approaches.

The well-known aromatic and medicinal plant Eupatorium fortunei Turcz. is widely cultivated in China, and previous studies on its bioactive constituents mainly focus on the essential oil ingredients especially thymol derivatives. However, reports on other type of constituents and the potential application are lacking.

Yin-Yang: Programming Abstractions for Cross-Domain Multi-Acceleration.

FPGA accelerators offer performance and efficiency gains by narrowing the scope of acceleration to one algorithmic domain. However, real-life applications are often not limited to a single domain, which naturally makes -Domain -Acceleration a crucial next step. The challenge is, existing FPGA accelerators are built upon their specific vertically-specialized stacks, which prevents utilizing multiple accelerators from different domains.

Anti-inflammatory labdane diterpenoids from the aerial parts of Leonurus japonicus.

Twenty-two labdane-type diterpenoids, including ten pairs of 15-epimers and a pair of 13,15-epimers, were obtained from the aerial parts of a well-known medicinal plant Leonurus japonicus Houtt. While these epimers were separated by chiral HPLC, their structures were established mainly via spectroscopic methods especially NMR, X-ray crystallography and ECD techniques. Among them, seventeen compounds, encompassing three pairs of solvolysis artefacts likely due to the use of ethanol as extracting solvent, were reported for the first time in the current work.

UHPLC-QQQ-MS/MS assay for the quantification of dianthrones as potential toxic markers of Polygonum multiflorum Thunb: applications for the standardization of traditional Chinese medicines (TCMs) with endogenous toxicity.

Background: The raw and processed roots of Polygonum multiflorum Thunb (PM) are commonly used in clinical practice to treat diverse diseases; however, reports of hepatotoxicity induced by Polygoni Multiflori Radix (PMR) and Polygoni Multiflori Radix Praeparata (PMRP) have emerged worldwide. Thus, it is necessary for researchers to explore methods to improve quality standards to ensure their quality and treatment effects.

Methods: In the present study, an ultra-high performance liquid chromatography triple quadrupole mass spectrometry (UHPLC-QQQ-MS/MS) method was optimized and validated for the determination of dianthrones in PMR and PMRP using bianthronyl as the internal standard.

A limbic circuitry involved in emotional stress-induced grooming.

Prolonged exposure to negative stressors could be harmful if a subject cannot respond appropriately. Strategies evolved to respond to stress, including repetitive displacement behaviours, are important in maintaining behavioural homoeostasis. In rodents, self-grooming is a frequently observed repetitive behaviour believed to contribute to post-stress de-arousal with adaptive value.

Estradiol-17β regulates proliferation and apoptosis of sheep endometrial epithelial cells by regulating the relative abundance of YAP1.

Yes-associated protein 1 (YAP1) transcription regulator of the Hippo protein kinase pathway, serves as a key regulator of tissue growth and organ size by regulating cell proliferation and apoptosis. Effects of YAP1 on proliferation and apoptosis of sheep endometrial epithelial cells (EEC) as a result of estradiol-17β (E) treatment, however, remain unclear. In the present study, the abundance of YAP1 protein in the uterine horn was greater than that in the uterine body or cervix.

Effects of nitric oxide on steroidogenesis and apoptosis in goat luteinized granulosa cells.

The aim of this study was to investigate effects of nitric oxide (NO) on steroidogenesis and apoptosis in goat luteinized granulosa cells (LGCs). We cultured goat LGCs from healthy follicles in culture medium supplemented with the NO donor sodium nitroprusside (SNP) or the NO synthase inhibitor N-Nitro-l-arginine methyl ester hydrochloride (l-NAME), then examined steroid synthesis, oxidative stress and apoptosis in vitro. The results showed that SNP treatment significantly increased the cGMP concentration in the LGCs (P < 0.

[Particle Size Distribution and Human Health Risk Assessment of Heavy Metals in Atmospheric Particles from Beijing and Xinxiang During Summer].

Under a condition of good air quality (AQI:55-90, PM:37-97 μg·m, PM:17-76 μg·m), six groups of 54 samples were collected using an Andersen cascade impactor from both the indoor and outdoor stations in Beijing and Xinxiang from June to August in 2016. The samples were digested by microwave digestion, and nine heavy metal elements (Pb, Cr, Ni, Cu, Zn, As, Cd, Mn, and Co) in the atmospheric particles were determined with an inductively coupled plasma source mass spectrometer (ICP-MS). The results showed that the enrichment index (0-3) of most elements were low in both cities except for Cd[15.
