Objective: To evaluate the prevalence of hypertension in older Mexicans in the United States and Mexico.
Methods: Stratified by sex, logistic regression models to predict physician-diagnosed hypertension were conducted by using the Hispanic Established Populations for Epidemiologic Study of the Elderly (wave 3) and the Mexican Health and Aging Study (age > or =70 years) datasets.
Results: Older Mexican and Mexican American women have a greater prevalence of hypertension than their male counterparts. Mexican women who have migrated to the United States and returned to Mexico have similarly high rates of hypertension as their female counterparts in the United States. After adjusting for demographic characteristics, diabetes, obesity, alcohol use, and smoking, older Mexican women who have migrated to the United States are at increased risk for hypertension. Conversely, immigrant older Mexican American men are at significantly lower odds of hypertension.
Conclusions: Sex differences exist in hypertension risk for older Mexicans and Mexican Americans living in the United States and Mexico. Older women who migrate to the United States are at a particular risk for hypertension in Mexico.

Mechanoluminescent units, when integrated into polymer matrices, undergo structural transformations in response to mechanical force, resulting in changes in fluorescence. This phenomenon holds considerable promise for the development of stress-sensing materials. Despite the high demand for robust, tunable mechanoluminescent mechanophores for force assessment and smart force-responsive materials, strategies for their design and synthesis remain underdeveloped.

Keeping track of time intervals is a crucial aspect of behavior and cognition. Many theoretical models of how the brain times behavior make predictions for steady-state performance of well-learned intervals, but the rate of learning intervals in these models varies greatly, ranging from one-shot learning to learning over thousands of trials. Here, we explored how quickly rats and mice adapt to changes in interval durations using a serial fixed-interval task.

Cellular senescence is a phenotypic state that contributes to the progression of age-related disease through secretion of pro-inflammatory factors known as the senescence-associated secretory phenotype (SASP). Understanding the process by which healthy cells become senescent and develop SASP factors is critical for improving the identification of senescent cells and, ultimately, understanding tissue dysfunction. Here, we reveal how the duration of cellular stress modulates the SASP in distinct subpopulations of senescent cells.

Purpose: To investigate how obesity affects the pharmacokinetics of biologics in a rat model.
Method: Male Long-Evans rats were fed a high-fat diet from the age of 3 weeks and development of obesity was monitored by measuring body size and composition (fat and lean mass). The animals received nivolumab (1 and 8 mg/kg) or recombinant human erythropoietin (rHuEPO, 1000 IU/kg) by intravenous or subcutaneous injection.

Examples of long-range gene regulation in bacteria are rare and generally thought to involve DNA looping. Here, using a combination of biophysical approaches including X-ray crystallography and single-molecule analysis for the KorB-KorA system in Escherichia coli, we show that long-range gene silencing on the plasmid RK2, a source of multi-drug resistance across diverse Gram-negative bacteria, is achieved cooperatively by a DNA-sliding clamp, KorB, and a clamp-locking protein, KorA. We show that KorB is a CTPase clamp that can entrap and slide along DNA to reach distal target promoters up to 1.
