We conducted and analysed semi-structured interviews to identify three comprehensive themes.

TClC effectively suppresses the growth and metastasis of NSCLC via polypharmacology.

Despite significant advances in targeted therapies and immunotherapies, non-small cell lung cancer (NSCLC) continues to present a global health challenge, with a modest five-year survival rate of 28 %, largely due to the emergence of treatment-resistant and metastatic tumors. In response, we synthesized a novel bioactive compound, ethyl 6-chlorocoumarin-3-carboxylyl L-theanine (TClC), which significantly inhibited NSCLC growth, epithelial mesenchymal transition (EMT), migration, and invasion and tumor growth and metastasis without inducing toxicity. TClC disrupts autocrine loops that promote tumor progression, particularly in stem-like CD133-positive NSCLC (CD133+ LC) cells, which are pivotal in tumor metastasis.

The Moderating Role of Educational Attainment in the Association between Social Support and Depressive Symptoms among African Americans.

General social support is commonly studied as a psychosocial resource that improves African Americans' well-being; we know less about how varied indicators of social support influence African Americans' depressive symptoms. Further, it is unclear how social support affects depressive symptoms differently when considering the moderating role of education. Using the National Survey of American Life (NSAL) (n = 3,278), we examined (1) the association between educational attainment and depressive symptoms, (2) the association between social support and depressive symptoms, and (3) whether education moderates the social support-depressive symptoms relationship among African Americans.

Quantitative and longitudinal assessment of human placental inflammation using diffusion basis spectrum imaging.

Besides exchanging nutrients, gases, and wastes, placenta is an intermediary between maternal and fetal immune systems. However, no method exists to safely image and monitor placental inflammation during pregnancy. We customized a Magnetic Resonance Imaging (MRI) method, diffusion basis spectrum imaging (DBSI), to measure immune cells in placenta.

Intraosseous basivertebral nerve ablation: A 5-year pooled analysis from three prospective clinical trials.

Background: Vertebrogenic pain is a documented source of anterior column chronic low back pain (CLBP) that stems from damaged vertebral endplates. Nociceptive signals are transmitted by the basivertebral nerve (BVN) and endplate damage is observed as Type 1 or Type 2 Modic changes (MC) on magnetic resonance imaging (MRI). The clinical impact and safety of intraosseous radiofrequency ablation of the BVN (BVNA) for the treatment of vertebrogenic pain has been demonstrated in three prospective clinical trials (two randomized and one single-arm study).

Whole Genome Sequencing Reveals Genetic Differences Between Symbiodiniaceae Populations Among Reproductively and Geographically Isolated Colonies in Western Australia.

Significant genetic differentiation between Symbiodiniaceae populations in coral hosts can be induced by a range of factors including geography, latitude, depth, temperature and light utilisation. The conventional method of measuring Symbiodiniaceae diversity involving the ITS2 region of rDNA has several limitations, stemming from insufficient genetic resolution and the multi-copy nature of the marker. This could be improved by using higher throughput whole genome sequencing to identify fine-scale population genetic differences and provide new insight into factors influencing coral-Symbiodiniaceae associations.

Multiple environmental tracers combined with a constrained Bayesian isotope mixing model to elucidate nitrate and sulfate contamination in a coastal groundwater system.

Several groundwater quality investigations have been conducted in coastal regions that are commonly exposed to multiple anthropogenic stressors. Nonetheless, such studies remain challenging because they require focused-diagnostic approaches for a comprehensive understanding of groundwater contamination. Therefore, this study integrates a multi-tracer approach to acquire comprehensive information allowing for an improved understanding of the origins of groundwater contamination, the relative contribution of contaminants, and their biogeochemical cycling within a coastal groundwater system.

Associations between cannabis use and same-day health and substance use behaviors.

Objective: Cannabis use has increased in the United States as states have legalized/decriminalized recreational and/or medicinal use. The primary aim of this study was to examine daily associations between cannabis use and health (physical activity [PA]) and substance use (alcohol consumption, cigarette use) behaviors.

Method: Data from a 28-day nationwide study that prompted daily ecological momentary assessments (EMAs) were used to assess daily cannabis use, moderate-to-vigorous PA (MVPA), alcohol containing drinks consumed, and cigarettes smoked.

The public health risks of counterfeit pills.

Synthetic illicit drugs, such as nitazenes and fentanyls, are becoming commonplace in countries around the world, including in Europe, Australia, and Latin America, which raises concern for overdose crises like those seen in North America. An important dimension of the risk represented by synthetic drugs is the fact that they are increasingly packaged in counterfeit pill form. These pills-often indistinguishable from authentic pharmaceuticals-have substantially widened the scope of populations susceptible to synthetic drug overdose in North America (eg, among adolescents experimenting with pills or tourists from the USA seeking psychoactive medications from pharmacies in Mexico).

Defining the optimal radiation-induced lymphopenia metric to discern its survival impact in esophageal cancer.

Background: A detrimental association between radiation-induced lymphopenia (RIL) and oncologic outcomes in esophageal cancer patients has been established. However, an optimal metric for RIL remains undefined, but is important for application of this knowledge in clinical decision-making and trial designs. The aim of this study was to find the optimal RIL metric discerning survival.

Comparative species delimitation of a biological conservation icon.

The United States Endangered Species Act (ESA) of 1973 set a precedent for biodiversity conservation across the globe. A key requirement of protections afforded by the ESA is the accurate delimitation of imperiled species. We present a comparative reference-based taxonomic approach to species delimitation that integrates genomic and morphological data for objectively assessing the distinctiveness of species targeted for protection by governmental agencies.
