Objectives: The singular focus on self-identified race and ethnicity in health disparities research may not fully convey the individual and structural components of experiencing race in society, or in a racialized context such as prison. Processes of racialization create boundaries between incarcerated individuals and regulate their daily interactions and access to resources, with possible effects on well-being. However, the relationship between perceived race and health has not been examined within the imprisoned population.

Article Synopsis
  • The natural compound 7α-acetoxy-6β-hydroxyroyleanone (Roy) has shown cytotoxic effects on various cancer cell lines.
  • Semi-synthetic derivatives of Roy were created and tested for their anticancer potential using computational methods, which included evaluating drug-likeness, toxicity risks, and binding interactions with cancer-related proteins.
  • The results pointed to strong anticancer properties across these derivatives, suggesting they could be promising candidates for chemotherapeutic development and warrant further experimental investigation.

The diterpene 7α-acetoxy-6β-hydroxyroyleanone isolated from demonstrates promising antibacterial, anti-inflammatory and anticancer properties. However, its bioactivity may be enhanced via strategic structural modifications of such natural products through semisynthesis. The anticancer potential of 7α-acetoxy-6β-hydroxyroyleanone and five derivatives was analyzed in silico via the prediction of chemicals absorption, distribution, metabolism, excretion, and toxicity (ADMET), quantum mechanical calculations, molecular docking and molecular dynamic simulation.

Patients with a mixed type of irritable bowel syndrome (IBS-M) experience constipation and diarrhea, which alternate between weeks or months. The pathogenesis of this syndrome is still little understood. The aim of the study was mainly to evaluate the urinary excretion of selected tryptophan (TRP) metabolites during the constipation and diarrhea periods of this syndrome.

Objectives: Similar to women overall, Black women are socialized to be communal and "self-sacrificing," but unlike women from other racial/ethnic backgrounds, Black women are also socialized to be "strong" and "invulnerable." This phenomenon is labeled Superwoman schema. This study examined associations between Superwoman schema endorsement and subjective sleep quality.

Gendered racial microaggressions reflect historical and contemporary gendered racism that Black women encounter. Although gendered racial microaggressions are related to psychological outcomes, it is unclear if such experiences are related to sleep health. Moreover, the health effects of gendered racial microaggressions dimensions are rarely investigated.

Due to the impact of nodal metastasis on colon cancer prognosis, adequate regional lymph node resection and accurate pathological evaluation are required. The ratio of metastatic to examined nodes may bring an additional prognostic value to the actual staging system. This study analyzes the identification of factors influencing a high lymph node yield and its impact on survival.

Bisphenols (BPs) have become a chemical group of special interest due to their ability to interfere with the endocrine system and their ubiquitous presence in the environment. As some of them possess mild estrogenic and anti-androgenic effects, they might be associated with the diagnosis of polycystic ovary syndrome (PCOS). Acting on multiple tissues, BPs exposure may lead to metabolic derangements characteristic for metabolic syndrome (MetS).

The Lamiaceae is one of the most important families in the production of essential oils known to have a wide spectrum of biological activity. Recent research has highlighted the dermatological capabilities of various Lamiaceae essential oils, which appear to offer potential in free radical scavenging and anti-inflammatory activity. Some have also been extensively studied for their tissue remodeling and wound-healing, anti-aging, anti-melanogenic, and anti-cancer properties.

Using nationally representative data from the Household Pulse Survey (April 2020-March 2021), we examined how associations between household job insecurity and mental health changed throughout the first year of the COVID-19 pandemic in the United States ( = 1,248,043). We also documented changes in the unequal distribution of job insecurity by race/ethnicity and educational attainment over time. We find that job insecurity was strongly associated with depression and anxiety throughout the study period, and the associations strengthened as the pandemic continued, especially in fall 2020.

The JAK/STAT signal pathway is a system of intracellular proteins used by many cytokines and growth factors to express genes responsible for the process of cell activation, proliferation and differentiation. There has been numerous inflammatory and autoimmune diseases identified where the JAK/STAT signaling is disrupted; however, there are only a few papers concerning autoimmune bullous diseases published. The aim of this study was to evaluate the expression of proteins: JAK3, STAT2, STAT4 and STAT6 in epithelium lesions in patients with pemphigus vulgaris (PV), bullous pemphigoid (BP), oral lichen planus (LP) and chronic ulcerative stomatitis (CUS), as well as in the control group.
