Assessment of the variability and correlation of biometric measurements in eyes with cataracts.

Purpose: To assess the variability and correlation of ocular biometric parameters in eyes with cataracts and examine their association with age and gender.

Methods: A retrospective analysis was performed on biometric data from 7,458 eyes without retinal pathologies, using an optical biometer equipped with low-coherence reflectometry technology. Pearson's correlation coefficients (r) were used to evaluate the relationships between age, gender, and various ocular parameters, including axial length (AL), anterior chamber depth (ACD), lens thickness (LT), central corneal thickness (CCT), corneal refractive power (Km), and white-to-white (WTW) measurement.

PBMC-mediated modulation of macrophage polarization in RAW264.7 cells through STAT1/STAT6 signaling cascades.

Peripheral blood mononuclear cells (PBMC), sourced autologously, offer numerous advantages when procured: easier acquisition process, no in vitro amplification needed, decreased intervention and overall increased acceptability make PBMC an attractive candidate for cell therapy treatment. However, the exact mechanism by which PBMC treat diseases remains poorly understood. Immune imbalance is the pathological basis of many diseases, with macrophages playing a crucial role in this process.

Small-Intensity Rainfall Triggers Greater Contamination of Rubber-Derived Chemicals in Road Stormwater Runoff from Various Functional Areas in Megalopolis Cities.

Rubber-derived chemicals (RDCs) originating from tire and road wear particles are transported into road stormwater runoff, potentially threatening organisms in receiving watersheds. However, there is a lack of knowledge on time variation of novel RDCs in runoff, limiting initial rainwater treatment and subsequent rainwater resource utilization. In this study, we investigated the levels and time-concentration profiles of 35 target RDCs in road stormwater runoff from eight functional areas in the Greater Bay Area, South China.

ABBV-744 alleviates LPS-induced neuroinflammation via regulation of BATF2-IRF4-STAT1/3/5 axis.

Suppression of neuroinflammation using small molecule compounds targeting the key pathways in microglial inflammation has attracted great interest. Recently, increasing attention has been gained to the role of the second bromodomain (BD2) of the bromodomain and extra-terminal (BET) proteins, while its effect and molecular mechanism on microglial inflammation has not yet been explored. In this study, we evaluated the therapeutic effects of ABBV-744, a BD2 high selective BET inhibitor, on lipopolysaccharide (LPS)-induced microglial inflammation in vitro and in vivo, and explored the key pathways by which ABBV-744 regulated microglia-mediated neuroinflammation.

Perceptions and self-management of a healthy diet among middle-aged adults with risk of stroke in North China: a qualitative exploration.

Objective: Although stroke is prevalent among older people, there is a rising incidence among the younger subpopulations, particularly middle-aged adults. A healthy diet is one of the key modifiable factors to primary prevention of stroke among these subpopulations, yet there is limited understanding of the dietary habits among middle agers who have the risk factor(s) but no occurrence of stroke. This study aims to explore the views on perceptions and the self-management of middle-aged adults at risk of stroke on a healthy diet and to identify the enablers and barriers that could inform the future development of dietary interventions.

[Exposure Level and Risk Impact Assessment of Pesticides and Veterinary Drugs in Aquaculture Environment].

To explore the exposure level of pesticides and veterinary drugs in an aquaculture environment and its impact on the ecological environment, this study took the aquaculture environment in Shanghai as an example, and samples of water, sediment, and inputs from 40 major aquaculture farms were collected from July to September 2022. The types and contents of pesticides and veterinary drugs were screened using high-performance liquid chromatography-electrostatic field orbital ion trap mass spectrometry, and the risk quotient (RQ) method was used to assess the ecological risk of pesticide contamination in water and sediment. The results showed that 13 drugs were screened out from 204 samples (72 samples of water, 72 samples of mud, and 60 samples of input), namely, chlorpromazine, carbendazim, thiophanate, diazepam, florfenicol, simazine, amantidine, diazepam, trimethoprim, ciprofloxacin, ofloxacin, mebendazole, and enrofloxacin.

A highly efficient liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay for etomidate and etomidate acid in urine, liver and kidney.

Etomidate (ETO) is a highly-efficient drug that can induce anesthesia with increasing doses, thus subject to strict regulation. However, an accurate and efficient method for ETO intake detection is currently lacking. Therefore, this study developed a straightforward sample preparation method using LC-MS/MS to analyze ETO and its primary metabolite, etomidate acid (ETA), in urine, liver, and kidney samples.

However, the activities of family members in sweet potatoes have not been analyzed. In the present study, the sweet potato cultivar 'Pushu 32', which is planted in a large area in China, was used in field experiments at the Agricultural Base of Hainan University (20°06' N, 110°33' E) in 2021, and Sanya Nanfan Research Institute of Hainan University (18°30' N, 109°60' E) in 2022.

A review on the mechanisms underlying the antitumor effects of natural products by targeting the endoplasmic reticulum stress apoptosis pathway.

Cancer poses a substantial risk to human life and wellbeing as a result of its elevated incidence and fatality rates. Endoplasmic reticulum stress (ERS) is an important pathway that regulates cellular homeostasis. When ERS is under- or overexpressed, it activates the protein kinase R (PKR)-like endoplasmic reticulum kinase (PERK)-, inositol-requiring enzyme 1 (IRE1)- and activating transcription Factor 6 (ATF6)-related apoptotic pathways to induce apoptosis.

Detection of Sarcopenia in a Community-Dwelling Older Population in China.

Background And Purpose: Sarcopenia is a common muscle disease among the older population, posing an increased risk for functional decline and intervention for loss of independence in daily living. Early detection of sarcopenia among older people before functional decline would be beneficial in enhancing their quality of life. The Asian Working Group for Sarcopenia (AWGS) 2019 recommends the use of 3 screening methods for community-based sarcopenia detection: calf circumference (CC), or the Strength, Assistance in walking, Rise from a chair, Climb stairs, and Falls (SARC-F) questionnaire, or the SARC-F in combination with CC (SARC-CalF) questionnaire.
