L-shaped association between leisure-time physical activity and depressive symptoms in individuals with chronic inflammatory airway disease: Data from the NHANES (2007-2018).

Background: Chronic inflammatory airway diseases (CIAD) are well-known risk factors for depression symptoms. There exists a complex interplay between leisure-time physical activity (LTPA) and depressive symptoms. However, the relationship between LTPA duration and depressive symptoms in CIAD patients remains unclear.

A novel function for α-synuclein as a regulator of NCK2 in olfactory bulb: implications for its role in olfaction.

To investigate physiological function of α-synuclein is important for understanding its pathophysiological mechanism in synucleinopathies including Parkinson's disease. Employing knockout mice, we found that Snac/α-synuclein deletion induced aberrant projection of olfactory sensory neurons and hyposmia. We identified 9 axon guidance associated differentially expressed proteins using iTRAQ based Liquid Chromatograph Mass Spectrometer.

Aerobic exercise improves BK channel-mediated vasodilation in diabetic vascular smooth muscle via AMPK/Nrf2/HO-1 pathway.

Aims: This study aims to investigate the effect of aerobic exercise training on BK channel in diabetic vascular smooth muscle and explore the underlying mechanism.

Methods: Control m/m mice and diabetic db/db mice were randomly assigned to sedentary groups (W and D) and exercise training groups (WE and DE). Mice in exercise groups underwent training sessions lasting for 12 weeks, with a speed of 12 m/min for 60 min, five times per week.

Association between physical activity dimensions and the risk of hypertension among middle and older adults: A cross-sectional study in China.

Background: It is known that insufficient physical activity is associated with the risk of hypertension, but the relationship to different physical activity dimensions within hypertension risk remains to be elucidated.

Objective: The objective of this study is to identify the association between physical activity intensity, frequency, duration, and volume with hypertension risk. Meanwhile, a dose-response experiment is conducted to determine the relationship between physical activity level and hypertension risk.

High-speed demodulation of weak fiber Bragg gratings based on microwave photonics and chromatic dispersion.

A high-speed demodulation technique based on microwave photonics and chromatic dispersion is proposed for distributed weak fiber Bragg gratings (FBGs). A broadband light modulated with a frequency-swept microwave is reflected by FBGs, and the reflected signal mixes with the original microwave to produce a beat frequency. A dispersion compensation fiber (DCF) changes the beat frequency within the FBG wavelength range.

Online Denoising Based on the Second-Order Adaptive Statistics Model.

Online denoising is motivated by real-time applications in the industrial process, where the data must be utilizable soon after it is collected. Since the noise in practical process is usually colored, it is quite a challenge for denoising techniques. In this paper, a novel online denoising method was proposed to achieve the processing of the practical measurement data with colored noise, and the characteristics of the colored noise were considered in the dynamic model via an adaptive parameter.

Thiophene-linked porphyrin derivatives for dye-sensitized solar cells.

Three novel organic dyes based on porphyrin derivatives were designed and synthesized for dye-sensitized solar cells, resulting in a maximum power conversion efficiency (eta) of 5.14% and a maximum IPCE value of 72% for a cell based on the dye.
