Differential cortical aspartate uptake across the oestrous cycle is associated with changes in gut microbiota in Wistar-Kyoto rats.

Pain and psychological stress are intricately linked, with sex differences evident in disorders associated with both systems. Glutamatergic signalling in the central nervous system is influenced by gonadal hormones via the hypothalamic-pituitary-adrenal axis and is central in pain research. Emerging evidence supports an important role for the gut microbiota in influencing pain signalling.

Marketing strategies in business-to-business advertisements for oral nicotine products.

Introduction: Although the popularity of oral nicotine products (ONPs) such as ZYN and On! is growing globally, there is limited research on their marketing and advertising. This report describes recent ONP marketing communication to retailers. Promotion to retailers can provide insight into new product flavours and styles, as well as future marketing strategies targeting consumers.

Comprehensive Assessment of Lifetime Cigarette Smoking and Its Association with Health-Related Quality of Life among Older US Adults-A Cross-sectional Study.

Background: Cigarette smoking is an established risk factor for lower health-related quality of life (HRQOL). Studies to date have not used comprehensive measures of tobacco exposures across the life course. We examined the association between a lifetime cigarette smoke exposure index (LCSEI) and HRQOL among older US adults.

Impact of low FODMAP sourdough bread on gut microbiota using an colonic fermentation model.

This study explores the development of whole-grain sourdough bread with reduced FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) content to offer dietary solutions for individuals with irritable bowel syndrome (IBS). Three sourdough breads were prepared using different lactic acid bacteria (LAB) strains including FST1.7 (SD-FST1.

Donor human milk: the influence of processing technologies on its nutritional and microbial composition.

Human milk is regarded as the gold standard nutrition for newborn infants, providing all nutrients required for adequate growth and development from birth to 6 months. In addition, human milk is host to an array of bioactive factors that confer immune protection to the newborn infant. For this reason, the supply of human milk is crucial for premature, seriously ill, or low birth weight infants (<1,500 g).

Black identity and internal health attributions of second generation black immigrant women.

Objective: Despite second generation Black immigrants being a rapidly growing population, they are often overlooked in health attribution research that treats Black populations as a monolithic group. Very few studies focus on how discrimination, societal pressure, and racial identity play a role in the health attributions of Black immigrant women. Even fewer studies have examined this relationship solely with second generation Black immigrant women.

Discussion of Heated Tobacco Products on Twitter Following IQOS's Modified-Risk Tobacco Product Authorization and US Import Ban: Content Analysis.

Background: Understanding public opinions about emerging tobacco products is important to inform future interventions and regulatory decisions. Heated tobacco products (HTPs) are an emerging tobacco product category promoted by the tobacco industry as a "better alternative" to combustible cigarettes. Philip Morris International's IQOS is leading the global HTP market and recently has been subject to important policy events, including the US Food and Drug Administration's (FDA) modified-risk tobacco product (MRTP) authorization (July 2020) and the US import ban (November 2021).

Yeast -glucan supplementation lowers insulin resistance without altering microbiota composition compared with placebo in subjects with type II diabetes: a phase I exploratory study.

The increased global prevalence of type II diabetes mellitus (T2DM) is associated with consumption of low fibre 'Western diets'. Characteristic metabolic parameters of these individuals include insulin resistance, high fasting and postprandial glucose, as well as low-grade systemic inflammation. Gut microbiota composition is altered significantly in these cohorts suggesting a causative link between diet, microbiota and disease.

Manipulating a host-native microbial strain compensates for low microbial diversity by increasing weight gain in a wild bird population.

Empirical studies from laboratory systems and humans show that the gut microbiota is linked to host health. Similar evidence for effects on traits linked to fitness in nature is rare, not least because experimentally manipulating the gut microbiota is challenging. We isolated, characterized, and cultured a bacterial strain, APC4233, directly from a wild bird (the great tit ) and provided it as a self-administered dietary supplement.

Flavor and Device Choices Among People Who Use ENDS: Results From the PATH Study.

Introduction: In guidance published in February 2020, the FDA described their intent to prioritize enforcement against the sale of flavored cartridge-based Electronic Nicotine Delivery Systems (ENDS) except tobacco and menthol flavors. This guidance was specific to cartridge-based ENDS and did not apply to other ENDS types or e-liquids sold in the U.S.

Geographical location, cigarette risk perceptions, and current smoking among older US adults.

Introduction: Cigarette smoking and smoking-related lung disease are more common in rural (vs urban) areas of the United States (US). This study examined relationships between geographical location, cigarette risk perceptions, and current smoking among older adults who are at greatest risk of developing smoking-related lung disease.

Methods: The study was a secondary data analysis of 12126 respondents aged ≥40 years from Wave 5 of the Population Assessment of Tobacco and Health Study.

Prospective Randomized Trial Comparing 2 Devices for Deep Inspiration Breath Hold Management in Breast Radiation Therapy: Results of the BRAVEHeart Trial.

Purpose: The Breast Radiotherapy Audio Visual Enhancement for sparing the Heart (BRAVEHeart) trial prospectively randomized patients with left-sided breast cancer to 1 of 2 deep inspiration breath hold biofeedback devices: a novel chest surface tracking system and an abdominal block tracking system. The primary hypothesis was that the accuracy of chest tracking would be higher than that of abdominal tracking as the chest is a more direct surrogate of the breast target.

Methods And Materials: Patients with left-sided breast cancer were treated in deep inspiration breath hold with intensity modulated radiation therapy delivery.

The glycolytic metabolite methylglyoxal covalently inactivates the NLRP3 inflammasome.

The NLRP3 inflammasome promotes inflammation in disease, yet the full repertoire of mechanisms regulating its activity is not well delineated. Among established regulatory mechanisms, covalent modification of NLRP3 has emerged as a common route for the pharmacological inactivation of this protein. Here, we show that inhibition of the glycolytic enzyme phosphoglycerate kinase 1 (PGK1) results in the accumulation of methylglyoxal, a reactive metabolite whose increased levels decrease NLRP3 assembly and inflammatory signaling in cells.

Somatic cell count as an indicator of subclinical mastitis and increased inflammatory response in asymptomatic lactating women.

Unlabelled: Subclinical mastitis is an asymptomatic inflammatory condition that can be difficult to define and diagnose. In the dairy industry, subclinical mastitis is diagnosed by milk somatic cell counts (SCCs) of ≥250,000 cells mL. In this pilot study, we assessed the efficacy of this index to identify human subclinical mastitis by comparing SCC levels with the inflammatory response [interleukin-8 (IL-8) levels] in 37 samples from asymptomatic and 10 clinical mastitis (CM) lactating women.
