Predicting physical functioning status in older adults: insights from wrist accelerometer sensors and derived digital biomarkers of physical activity.

Objective: Conventional physical activity (PA) metrics derived from wearable sensors may not capture the cumulative, transitions from sedentary to active, and multidimensional patterns of PA, limiting the ability to predict physical function impairment (PFI) in older adults. This study aims to identify unique temporal patterns and develop novel digital biomarkers from wrist accelerometer data for predicting PFI and its subtypes using explainable artificial intelligence techniques.

Materials And Methods: Wrist accelerometer streaming data from 747 participants in the National Health and Aging Trends Study (NHATS) were used to calculate 231 PA features through time-series analysis techniques-Tsfresh.

Effect and influence mechanism of biofilm formation on the biological stability of reclaimed water.

Microorganisms and sediments in reclaimed water adhere to the inner walls of pipes or water tanks, forming biofilms that support the continuous growth of microorganisms. These biofilms provide a protective barrier, shielding bacteria from disinfectants. This study investigated the impact of biofilms on bacterial growth and reproduction in reclaimed water and the factors limiting bacterial growth in reclaimed graywater (GMR) and reclaimed mixed wastewater (MWR).

Transmission of Microcystins in Natural Systems and Resource Processes: A Review of Potential Risks to Humans Health.

The rapid rise of microcystins (MCs) poses a serious threat to global freshwater ecosystems and has become an important issue of global public health. MCs have considerable stability and are the most widely distributed hepatotoxins. It cannot only accumulate in aquatic organisms and transfer to higher nutrients and levels, but also be degraded or transferred during the resource utilization of cyanobacteria.

Design of a Synthetic Strategy to Achieve Enhanced Fluorescent Carbon Dots with Sulfur and Nitrogen Codoping and Its Multifunctional Applications.

Here, a rational strategy to achieve multifunctional N, S codoped carbon dots (N, S-CDs) is reported, aiming to improve the photoluminescence quantum yields (PLQYs) of the CDs. The synthesized N, S-CDs have excellent stability and emission properties independent of excitation wavelength. Through the introduction of S element doping, the fluorescence emission of CDs is red-shifted from 430 to 545 nm, and the corresponding PLQYs can be greatly enhanced from 11.

Bufalin inhibits the proliferation of lung cancer cells by suppressing Hippo-YAP pathway.

Lung cancer has high morbidity and mortality. This study demonstrated that Bufalin inhibits the proliferation of lung cancer cells in vivo / in vitro by suppressing Hippo-YAP pathway. Here, we found that Bufalin promoted the binding of LATS and YAP to elevate the level of YAP phosphorylation.

IGF2BP3 is an essential N-methyladenosine biotarget for suppressing ferroptosis in lung adenocarcinoma cells.

A lack of promising targets leads to poor prognosis in patients with lung adenocarcinoma (LUAD). Therefore, it is urgent to identify novel therapeutic targets. The importance of the N-methyladenosine (mA) RNA modification has been demonstrated in various types of tumors; however, knowledge of mA-related proteins in LUAD is still limited.

Association of serum VLDL level with hyperhomocysteinemia in hypertensive patients: A cross-sectional study.

Background: Increasing evidence suggests that hyperhomocysteinemia (HHcy) and hyperlipidemia have been recognized as two independent risks for cardiovascular disease. However, the association between hyperlipidemia and HHcy in hypertensive patients has not been systemically elucidated. The aim of this study was to investigate the relation between very low-density lipoprotein (VLDL) and HHcy in hypertensive patients.

Determination of Isosorbide-5-Mononitrate in Human Plasma by High-Performance Liquid Chromatography-Tandem Mass Spectrometry and Its Application to a Bioequivalence Study.

Isosorbide-5-mononitrate (5-ISMN), an organic nitrate vasodilator, has been widely used worldwide to prevent angina pectoris for more than two decades. A simple and sensitive high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method was developed and validated for the determination of 5-ISMN in human plasma. C-5-ISMN is an internal standard, and 5-ISMN was extracted from human plasma (50 L) with ethyl acetate (200 L) by a simple liquid-liquid extraction method.
