S-glutathionylation (SSG) is increasingly recognized as a critical signaling mechanism in the heart, yet SSG modifications in cardiac sarcomeric proteins remain understudied. Here we identified SSG of the ventricular isoform of myosin light chain 1 (MLC-1v) in human, swine, and mouse cardiac tissues using top-down mass spectrometry (MS)-based proteomics. Our results enabled the accurate identification, quantification, and site-specific localization of SSG in MLC-1v across different species.

Article Synopsis
  • Hymenoptera is an insect order that includes species like honeybees and wasps, and their venom can cause severe allergic reactions in dogs, similar to humans.
  • A study examined the medical histories of 178 dogs stung by these insects to understand risk factors for severe systemic reactions (SSRs), finding that younger dogs, smaller breeds, and those stung in sensitive areas faced higher risks.
  • The research highlighted that many dogs with SSRs experienced similar or worse symptoms upon subsequent stings, indicating a strong case for using venom immunotherapy (VIT) for affected dogs.

Background/objectives: The Strengths and Difficulties Questionnaire (SDQ) is a widely used 25-item screening and diagnostic tool for behavioral and emotional problems in young people. Despite its popularity, evaluations of the SDQ's factor structure in adolescent populations have produced disparate results, and its relationships with theoretically related variables are rarely evaluated. In the present study, these two elements of validity were evaluated based on a large sample of Western Australian adolescents.

Article Synopsis
  • Aquatic species in productive coastal habitats experience dynamic changes in water temperature and oxygen levels, but the impact of these fluctuations on their thermal tolerance is not well understood.
  • The research hypothesizes that the predictability of these diel (daily) environmental changes can explain how different marine species respond to temperature shifts.
  • Results indicate that tropical species face more predictable fluctuations, allowing them to adjust their thermal performance under high oxygen levels, suggesting predictability should be considered in models forecasting marine responses to global warming.

  • Pediatric long COVID is still not fully understood, and this study aimed to explore its impact on children and adolescents following the 2021 Delta variant outbreak in Australia.
  • Out of 11,864 surveyed parents, 17.6% responded, with 11.7% of children reporting ongoing symptoms or functional impairment; only a small fraction were classified as having Long COVID.
  • The findings suggest that while most children recover within 12 weeks, a notable minority may experience long-term symptoms, highlighting the need for further attention and research on risk factors like age and previous health issues.

In this study, a brief measure of four internal attributes found to protect against the impact of adverse life events on mental health was developed and validated. In addition, profiles of internal strengths that significantly predict mental health outcomes in young Chinese adults were identified. The results of exploratory and confirmatory factor analyses on data from 831 Chinese university students supported the proposed four-factor model of the ISALES.

Fragile X Syndrome (FXS) is the most common inherited form of intellectual disability and is caused by mutations in the gene encoding the Fragile X messenger ribonucleoprotein (FMRP). FMRP is an evolutionarily conserved and neuronally enriched RNA-binding protein (RBP) with functions in RNA editing, RNA transport, and protein translation. Specific target RNAs play critical roles in neurodevelopment, including the regulation of neurite morphogenesis, synaptic plasticity, and cognitive function.

Background: A conceptual model of effective symptom management was previously developed from interviews with multidisciplinary healthcare professionals (HCP) working in English hospices. Here we aimed to answer the question; does a HCP data-derived model represent the experience of patients and carers of people with advanced cancer?

Methods: Semi-structured interviews were undertaken with six patients with advanced cancer and six carers to gain an in-depth understanding of their experience of symptom management. Analysis was based on the framework method; transcription, familiarisation, coding, applying analytical framework (conceptual model), charting, interpretation.

Hoarding disorder (HD) and obsessive-compulsive disorder (OCD) are highly comorbid and genetically related, but their similarities and differences at the neural level are not well characterized. The present study examined the time-frequency information contained in stimulus-related EEG data as participants worked on a visual flanker task. Three groups were included: participants diagnosed with HD (N = 33), OCD (N = 26), and healthy controls (N = 35).

We recently reported on small-molecule inhibitors of the GroES/GroEL chaperone system as potential antibiotics against and the ESKAPE pathogens but were unable to establish GroES/GroEL as the cellular target, leading to cell death. In this study, using two of our most potent -sulfonamido-2-phenylbenzoxazoles (PBZs), we established the binding site of the PBZ molecules using cryo-EM and found that GroEL was the cellular target responsible for the mode of action. Cryo-EM revealed that PBZ1587 binds at the GroEL ring-ring interface (RRI).

Native top-down mass spectrometry (nTDMS) allows characterization of protein structure and noncovalent interactions with simultaneous sequence mapping and proteoform characterization. The majority of nTDMS studies utilize purified recombinant proteins, with significant challenges hindering application to endogenous systems. To perform native top-down proteomics (nTDP), where endogenous proteins from complex biological systems are analyzed by nTDMS, it is essential to separate proteins under nondenaturing conditions.

Most chemistry and biology occurs in solution, in which conformational dynamics and complexation underlie behaviour and function. Single-molecule techniques are uniquely suited to resolving molecular diversity and new label-free approaches are reshaping the power of single-molecule measurements. A label-free single-molecule method capable of revealing details of molecular conformation in solution would allow a new microscopic perspective of unprecedented detail.
