Drought is an abiotic stress that decreases crop photosynthesis, growth, and yield. Ascorbic acid has been used as a seed preconditioning agent to help mitigate drought in some species, but not yet in broccoli ( var. ).

However, in cancer cells, GRP78 has also been shown to migrate from the ER lumen to the cell surface, playing a role in several cellular pathways that promote tumor growth and cancer cell progression. There is another insidious consequence elicited by cell surface GRP78 (csGRP78) on cancer cells: the accumulation of csGRP78 represents a novel neoantigen leading to the production of anti-GRP78 autoantibodies that can bind csGRP78 and further amplify these cellular pathways to enhance cell growth and mitigate apoptotic cell death.

As part of a larger community-based participatory project in Nunavik, Northern Québec, we travelled to two communities to gather perspectives from Inuit women and healthcare professionals (HCPs) on CC screening services and the possible implementation of HPV self-sampling. We held 10 group discussions with 28 Inuit women and 10 semi-structured interviews with 20 HCPs.

A better understanding of how both groups differentially experience their partnership could help identify strategies to improve collaboration in patient engagement research.
Aim: This study aimed to describe and compare patient partners' and academic researchers' experiences in patient engagement research.
Exercise-based cardiac rehabilitation leads to improvements in cardiovascular function in individuals with coronary artery disease. The cardiac effects of coronary artery disease (CAD) can be quantified using clinical echocardiographic measures, such as ejection fraction (EF). Measures of cardiovascular function typically only used in research settings can provide additional information and maybe more sensitive indices to assess changes after exercise-based cardiac rehabilitation.

The objective of the study was to better understand lower cost 10.6 eV photoionization detector (PID)-based volatile organic compound (VOC) sensors and investigate their utility for near-source emissions detection applications.

The aims of this study were to (1) quantify the protection provided by masks (surgical, fit-testFAILED N95, fit-testPASSED N95) and personal protective equipment (PPE), and (2) determine if a portable high-efficiency particulate air (HEPA) filter can enhance the benefit of PPE.
Methods: Virus aerosol exposure experiments using bacteriophage PhiX174 were performed.
A pancreaticopleural fistula (PPF) is a rare complication of chronic pancreatitis secondary to a pancreatic pseudocyst or any disruption of the main pancreatic duct. It commonly presents as a recurrent left-sided pleural effusion after multiple thoracentesis. We present a rare case of a 41-year-old woman with numerous flares of chronic pancreatitis presenting with large bilateral serosanguinous pleural effusions and trapped lung secondary to a PPF.

Interval chest imaging following this procedure demonstrated worsening right upper lobe opacities and a right-sided pleural effusion. Bronchoscopies identified copious mucoid secretions and an infected bronchocoele with a right upper lobe airways impaction.

This systematic review and meta-analysis ) examined the effects of acute exercise and exercise training on cerebrovascular hemodynamic variables reported in the stroke exercise literature and ) synthesized the peak middle cerebral artery blood velocity (MCAv) achieved during an acute bout of moderate-intensity exercise in individuals after stroke. Six databases (Medline, Embase, Web of Science, CINAHL, PsycINFO, AMED) were searched from inception to December 1st, 2021 for studies that examined the effect of acute exercise or exercise training on cerebrovascular hemodynamics in adults after stroke.

Objectives: This study aimed to establish if practitioners who provide OST are experiencing negative outcomes, specifically aggression, distress, and burnout, and to identify if workload and professional affiliation were associated with these risks.
Objective: To identify lessons learned locally from the invasive cervical cancer audit. To estimate the impact that the application of 'Duty of Candour' may have upon our future service provision.
Methods: Retrospective cohort study with interval analysis of all women diagnosed with cervical cancer at Sheffield Teaching Hospitals NHS Foundation Trust between 1 April 2007 to 31 December 2019.
Background: To combat historical underrepresentation of female participants in research, guidelines have been established to motivate equal participation by both sexes. However, the pervasiveness of female exclusion has not been examined in vascular exercise physiology research. The purpose of this study was to systematically quantify the sex-specific prevalence of human participants and identify the rationales for sex-specific inclusion/exclusion in research examining the impact of exercise on vascular endothelial function.

Data Sources: Four databases (MEDLINE, Embase, PsycINFO, SPORTDiscus) were searched from inception up until September 1, 2020, and updated November 18, 2021.
Study Selection: Searches combined keywords relating to the topics: SCI, subjective measures of exercise intensity, and exercise.
The COVID-19 pandemic notably altered adolescent substance use during the initial stage (Spring 2020) of the pandemic. The purpose of this longitudinal study is to examine trajectories of adolescent substance use across the pandemic and subsequent periods of stay-at-home orders and re-opening efforts. We further examined differences as a function of current high school student versus graduate status.

While the number of children with medical complexity is small, they use a significant amount of health resources across various health settings and sectors. Research to date exploring this pediatric population has relied primarily on quantitative or qualitative data alone, leaving significant gaps in our understanding of this population.
View Article and Find Full Text PDFThe age at onset of motor symptoms in Huntington's disease (HD) is driven by HTT CAG repeat length but modified by other genes. In this study, we used exome sequencing of 683 patients with HD with extremes of onset or phenotype relative to CAG length to identify rare variants associated with clinical effect. We discovered damaging coding variants in candidate modifier genes identified in previous genome-wide association studies associated with altered HD onset or severity.
View Article and Find Full Text PDFin motor planning and in language planning refer to the influence of prior production history on current production behaviour. Computational efficiency accounts of action hysteresis and theoretical accounts of syntactic priming both argue that reusing an existing plan is less costly than generating a novel plan. Despite these similarities across motor and language frameworks, research on planning in these domains has largely been conducted independently.

Methods: This study was a content analysis based on the Standards for Reporting Qualitative Research guidelines. Purposive sampling of 10 Italian osteopaths was applied.
Genome-wide association studies (GWASs) of Huntington disease (HD) have identified six DNA maintenance gene loci (among others) as modifiers and implicated a two step-mechanism of pathogenesis: somatic instability of the causative HTT CAG repeat with subsequent triggering of neuronal damage. The largest studies have been limited to HD individuals with a rater-estimated age at motor onset. To capitalize on the wealth of phenotypic data in several large HD natural history studies, we have performed algorithmic prediction by using common motor and cognitive measures to predict age at other disease landmarks as additional phenotypes for GWASs.
