Calcium (Ca ) ions affect nearly all aspects of biology. Excessive Ca entry is cytotoxic and Ca - mobilizing receptors have evolved diverse mechanisms for tight regulation that often include Calmodulin (CaM). TRPA1, an essential Ca -permeable ion channel involved in pain signaling and inflammation, exhibits complex Ca regulation with initial channel potentiation followed by rapid desensitization.

Protein tandem mass spectrometry data are most often interpreted by matching observed mass spectra to a protein database derived from the reference genome of the sample being analyzed. In many application domains, however, a relevant protein database is unavailable or incomplete, and in such settings de novo sequencing is required. Since the introduction of the DeepNovo algorithm in 2017, the field of de novo sequencing has been dominated by deep learning methods, which use large amounts of labeled mass spectrometry data to train multi-layer neural networks to translate from observed mass spectra to corresponding peptide sequences.

Article Synopsis
  • SGM individuals often receive poorer palliative care, and this study aims to explore palliative care physicians' attitudes and practices towards providing care for these communities.
  • Through interviews with 24 physicians across Canada, four key themes emerged: increased knowledge boosts clinician confidence; standardizing SOGI data collection improves care; addressing biases enhances service; and understanding SOGI leads to better care outcomes.
  • The study highlights the necessity for tailored training and policy implementation to better meet the unique needs of SGM patients in palliative care settings.

A key parameter of any bottom-up proteomics mass spectrometry experiment is the identity of the enzyme that is used to digest proteins in the sample into peptides. The Casanovo de novo sequencing model was trained using data that was generated with trypsin digestion; consequently, the model prefers to predict peptides that end with the amino acids "K" or "R". This bias is desirable when Casanovo is used to analyze data that was also generated using trypsin but can be problematic if the data was generated using some other digestion enzyme.

Article Synopsis
  • - The study explores the role of race dialogues, or discussions about race and racism among people of different racial backgrounds, in improving medical practices and patient experiences for racially minoritized groups.
  • - A scoping review analyzed 54 articles focusing on the necessary preparations, leadership qualities, and follow-up needed for effective race dialogues, highlighting the importance of trauma-informed practices and the need to center minoritized voices.
  • - Implementing race dialogues in medicine can foster a more inclusive environment, enhance colleague relationships, and ultimately lead to better care for patients from diverse racial identities.

Zebrafish (Danio rerio) is now the second most used animal model in biomedical research. As with other vertebrate models, underlying diseases and infections often impact research. Beyond mortality and morbidity, these conditions can compromise research end points by producing nonprotocol induced variation within experiments.

Motivation: One of the core problems in the analysis of protein tandem mass spectrometry data is the peptide assignment problem: determining, for each observed spectrum, the peptide sequence that was responsible for generating the spectrum. Two primary classes of methods are used to solve this problem: database search and de novo peptide sequencing. State-of-the-art methods for de novo sequencing use machine learning methods, whereas most database search engines use hand-designed score functions to evaluate the quality of a match between an observed spectrum and a candidate peptide from the database.

Background: Ethnically Chinese adults in Canada and the United States face multiple barriers in accessing equitable, culturally respectful care at the end-of-life. Palliative care (PC) is committed to supporting patients and families in achieving goal-concordant, high-quality serious illness care. Yet, current PC delivery may be culturally misaligned.

Article Synopsis
  • Interventions aimed at improving care for seriously ill patients often do not reach marginalized communities, including racialized, indigenous, and rural populations, despite their demonstrated benefits.
  • The study focused on understanding the implementation of the Serious Illness Care Program in healthcare systems that primarily serve these underserved groups by conducting qualitative interviews and focus groups with healthcare team members.
  • Three main themes were identified regarding implementation factors: patient-related challenges, specific elements of the intervention, and the health system's context; notable barriers include resource limitations and mistrust in healthcare, while mission-driven efforts and interprofessional collaboration were seen as supportive factors.

Early palliative care, palliative care integrated with oncology care early in the course of illness, has myriad benefits for patients and their caregivers, including improved quality of life, reduced physical and psychological symptom burden, enhanced prognostic awareness, and reduced health care utilization at the end of life. Although ASCO and others recommend early palliative care for all patients with advanced cancer, widespread implementation of early palliative care has not been realized because of barriers such as insufficient reimbursement and a palliative care workforce shortage. Investigators have recently tested several implementation strategies to overcome these barriers, including triggers for palliative care consultations, telehealth delivery, navigator-delivered interventions, and primary palliative care interventions.

Membrane-bound particles in plasma are composed of exosomes, microvesicles, and apoptotic bodies and represent ~1-2% of the total protein composition. Proteomic interrogation of this subset of plasma proteins augments the representation of tissue-specific proteins, representing a "liquid biopsy," while enabling the detection of proteins that would otherwise be beyond the dynamic range of liquid chromatography-tandem mass spectrometry of unfractionated plasma. We have developed an enrichment strategy (Mag-Net) using hyper-porous strong-anion exchange magnetic microparticles to sieve membrane-bound particles from plasma.

Background: Health disparities exist in end-of-life (EOL) care. Individuals and communities that are marginalized due to their race, ethnicity, income, geographic location, language, or cultural background experience systemic barriers to access and receive lower quality EOL care. Advance care planning (ACP) prepares patients and their caregivers for EOL decision-making for the purpose of promoting high-quality EOL care.

Community surveillance surveys offer an opportunity to obtain important and timely public health information that may help local municipalities guide their response to public health threats. The objective of this paper is to present approaches, challenges, and solutions from SARS-CoV-2 surveillance surveys conducted in different settings by 2 research teams. For rapid assessment of a representative sample, a 2-stage cluster sampling design was developed by an interdisciplinary team of researchers at Oregon State University between April 2020 and June 2021 across 6 Oregon communities.

Background: Psychedelic-assisted therapies (PAT) are emerging as a promising treatment for psycho-existential distress in patients with serious illness. A recent qualitative analysis of perspectives of 17 experts in serious illness care and/or PAT research identified divergent views on the therapeutic potential and safety of PAT in patients with serious illness. This paper further analyzes the factors that may influence these views.
