Climate change is imposing multiple stressors on marine life, leading to a restructuring of ecological communities as species exhibit differential sensitivities to these stressors. With the ocean warming and wind patterns shifting, processes that drive thermal variations in coastal regions, such as marine heatwaves and upwelling events, can change in frequency, timing, duration, and severity. These changes in environmental parameters can physiologically impact organisms residing in these habitats.

Around the world, a significant proportion of sewers and sewer maintenance holes are constructed from concrete. Unfortunately, one major problem with concrete sewer infrastructure is corrosion caused by biogenic hydrogen sulphide, which causes major issues for concrete structural integrity. Furthermore, concrete may be significantly corroded and softened but still pass a visual inspection.

Unprofessional behaviour within cardiology has been well documented and commonly occurs within the cardiac catheterisation laboratory, with higher rates in interventional subspecialities. While most trainees have positive experiences and encounters within the catheterisation laboratory, around one in five report experiencing bullying. This not only has a significant negative impact on the individuals directly involved, but also on the wider multidisciplinary team; importantly, it will have a deleterious effect on patient safety.

Objective: Electrical hazards on farms are one of the occupational risks that contributes to farm injury and fatality. Whilst electricity accounts for a low number of farm injuries each year, it is disproportionately fatal. The aim of this study is to raise the awareness of electrical safety on farms by providing an overview of the literature that explores the evidence of farmers' perception of electrical risk.

  • Recent advancements in targeted protein degradation, particularly utilizing Lysosome-Targeting Chimeras (LYTACs), enable effective clearance of extracellular proteins through unique mechanisms involving the mannose 6-phosphate receptor (M6PR).
  • A novel method has been developed to create site-specific antibody-mannose 6-phosphate (M6P) conjugates using a synthetic M6P glycan called bisM6P combined with an engineered antibody devoid of effector functions, allowing for selective targeting.
  • This M6P-conjugated antibody successfully internalizes and degrades target proteins like human tumor necrosis factor (TNF) in cancer and immune cells, through the endo-

  • Cutaneous leishmaniasis (CL) in Ethiopia, caused by the Leishmania aethiopica parasite, shows multiple clinical forms that are not linked to genetic differences in the parasite's genome or variations in immune system responses among patients.
  • A study analyzed genetic data from 48 parasite isolates and immune signatures from 129 CL patients, finding no significant associations between the genetic variants or immune markers and the different clinical presentations of CL.
  • The research concluded that while there were some differences in chemokines when comparing CL patients to healthy controls, the overall immune response did not significantly vary between the clinical forms of CL.

The ability to notice and reflect on distressing internal experiences from an objective perspective, often called psychological decentering, has been posited to be protective against mental health difficulties. However, little is known about how this skill relates to age across adolescence, its relationship with mental health, and how it may impact key domains such as affective executive control and social cognition. This study analysed a pre-existing dataset including mental health measures and cognitive tasks, administered to adolescents in Greater London and Cambridge (mean age (SD) = 14.

Mass-drug administration (MDA) of human populations using praziquantel monotherapy has become the primary strategy for controlling and potentially eliminating the major neglected tropical disease schistosomiasis. To understand how long-term MDA impacts schistosome populations, we analysed whole-genome sequence data of 570 samples (and the closely related outgroup species, from eight countries incorporating both publicly-available sequence data and new parasite material. This revealed broad-scale genetic structure across countries but with extensive transmission over hundreds of kilometres.

Article Synopsis
  • The text discusses a parasitic flatworm's life cycle, focusing on the miracidium stage which infects freshwater snails to eventually cause schistosomiasis in humans.
  • Researchers created a detailed cellular atlas revealing the 365 cells in the miracidium and identified 19 distinct cell clusters through single-cell RNA sequencing.
  • The study found that most of the larva's cells are somatic, with a small percentage being stem cells, and the stem cells display distinct characteristics potentially related to sex.

Cutaneous leishmaniasis (CL) is a neglected tropical disease caused by Leishmania parasites, that can cause long-term chronic disabilities. The clinical presentation of CL varies in both type and severity. CL presents as three main clinical forms: localised lesions (localised cutaneous leishmaniasis, LCL); mucocutaneous leishmaniasis (MCL) that affects the mucosa of the nose or the mouth; or as disseminated not ulcerating nodules (diffuse cutaneous leishmaniasis, DCL).

Modulation of the cervix by steroid hormones and commensal microbiome play a central role in the health of the female reproductive tract. Here we describe organ-on-a-chip (Organ Chip) models that recreate the human cervical epithelial-stromal interface with a functional epithelial barrier and production of mucus with biochemical and hormone-responsive properties similar to living cervix. When Cervix Chips are populated with optimal healthy versus dysbiotic microbial communities (dominated by Lactobacillus crispatus and Gardnerella vaginalis, respectively), significant differences in tissue innate immune responses, barrier function, cell viability, proteome, and mucus composition are observed that are similar to those seen in vivo.
