Unveiling cryptic macroinvertebrate sentinels to enhance biomonitoring in tropical rivers: Bridging traditional approaches with DNA barcoding in the Indo-Burma biodiversity hotspot.

Human activities present significant threats to tropical freshwater ecosystems, notably in many global biodiversity hotspots, threats that are further increased by inadequate taxonomic knowledge and the lack of appropriate biomonitoring tools. This study integrates globally validated biomonitoring approaches with DNA-based identification methods to create a macroinvertebrate-based tool for diagnosing ecosystem health and assessing the biodiversity of tropical river ecosystems in Myanmar (Indo-Burma bioregion). To evaluate river site degradation, comprehensive data on water and habitat quality, as well as land use information, were collected.

Multiple stressor effects act primarily on microbial leaf decomposers in stream mesocosms.

At the global level, stream ecosystems are influenced by multiple anthropogenic stressors such as eutrophication, habitat deterioration, and water scarcity. Multiple stressor effects on stream biodiversity are well documented, but multiple stressor effects on stream ecosystem processes have received only limited attention. We conducted one mesocosm (stream channel) and one microcosm (feeding trial) experiment to study how combinations of reduced flow, increased nutrient concentrations, and increased fine sediment coverage would influence fungal and macroinvertebrate decomposer assemblages and their active contribution to leaf decomposition.

Evaluation of five different methods for diagnosis of Helicobacter pylori from fecal samples.

Accurate detection of Helicobacter pylori and its antimicrobial resistance is essential for eradication of the infections. The aim of this study was to compare five different CE-IVD marked assays in detection of H. pylori from 268 clinical stool samples.

Because I see you: Pharmacist social determinants of health as predictor of structural awareness.

Background: The contribution of social determinants of health (SDOH) to health disparities and patient outcomes is widely acknowledged. Much less has been done to characterize provider SDOH, and in particular, their effect on delivery of structurally competent care. Differing lived experiences create blind spots to the critical upstream factors contributing to health.
