Physician Assistant Program Accreditation Analysis and Survey of Program Directors.

Introduction: To inform physician assistant program directors through citation analysis after implementation of the Accreditation Review Commission on Education for the Physician Assistant (ARC-PA) Accreditation Standards, 5th edition.

Methods: This research used descriptive statistics, Pearson correlation, and the coefficient of determination to analyze the citations reported by ARC-PA during January 2021 to February 2023. Concurrent first-time taker Physician Assistant National Certifying Exam (PANCE) results were used to determine whether a correlation exists between pass rates and citations.

Stressed and Depressed: Prevalence of Anxiety and/or Depression in Physician Assistant Students.

Introduction: This research highlights the prevalence of anxiety and/or depression among physician assistant (PA) students compared with the general population. It is believed that the results of this study will encourage graduate programs to place a stronger emphasis on the mental health of students and create a more positive learning environment.

Methods: An original survey was created using questions from Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, and several original questions.

Substance Use Among Physician Assistant Students: A National Study on the Prevalence of Alcohol, Tobacco, Illicit Substances, and Medication Use.

Introduction: The purpose of this study was to discover the substance use prevalence among physician assistant students (PA-S) compared with the age-relevant general US population and to examine the frequency of stress, burnout, anxiety, and depression during the didactic and clinical phases, while accounting for the impact of the COVID-19 pandemic.

Methods: A 20-item survey instrument was created. Self-reported data included demographics, anxiety, burnout, tobacco, illicit substances, and prescription medication use.

Loss of CENP-F results in distinct microtubule-related defects without chromosomal abnormalities.

Microtubule (MT)-binding centromere protein F (CENP-F) was previously shown to play a role exclusively in chromosome segregation during cellular division. Many cell models of CENP-F depletion show a lag in the cell cycle and aneuploidy. Here, using our novel genetic deletion model, we show that CENP-F also regulates a broader range of cellular functions outside of cell division.

Bves and NDRG4 regulate directional epicardial cell migration through autocrine extracellular matrix deposition.

Directional cell movement is universally required for tissue morphogenesis. Although it is known that cell/matrix interactions are essential for directional movement in heart development, the mechanisms governing these interactions require elucidation. Here we demonstrate that a novel protein/protein interaction between blood vessel epicardial substance (Bves) and N-myc downstream regulated gene 4 (NDRG4) is critical for regulation of epicardial cell directional movement, as disruption of this interaction randomizes migratory patterns.

Cardiac-specific deletion of the microtubule-binding protein CENP-F causes dilated cardiomyopathy.

CENP-F is a large multifunctional protein with demonstrated regulatory roles in cell proliferation, vesicular transport and cell shape through its association with the microtubule (MT) network. Until now, analysis of CENP-F has been limited to in vitro analysis. Here, using a Cre-loxP system, we report the in vivo disruption of CENP-F gene function in murine cardiomyocytes, a cell type displaying high levels of CENP-F expression.

Concerted effort of centrosomal and Golgi-derived microtubules is required for proper Golgi complex assembly but not for maintenance.

Assembly of an integral Golgi complex is driven by microtubule (MT)-dependent transport. Conversely, the Golgi itself functions as an unconventional MT-organizing center (MTOC). This raises the question of whether Golgi assembly requires centrosomal MTs or can be self-organized, relying on its own MTOC activity.

Murine CENP-F regulates centrosomal microtubule nucleation and interacts with Hook2 at the centrosome.

The microtubule (MT) network is essential in a broad spectrum of cellular functions. Many studies have linked CENP-F to MT-based activities as disruption of this protein leads to major changes in MT structure and function. Still, the basis of CENP-F regulation of the MT network remains elusive.

Golgi-derived CLASP-dependent microtubules control Golgi organization and polarized trafficking in motile cells.

Microtubules are indispensable for Golgi complex assembly and maintenance, which are integral parts of cytoplasm organization during interphase in mammalian cells. Here, we show that two discrete microtubule subsets drive two distinct, yet simultaneous, stages of Golgi assembly. In addition to the radial centrosomal microtubule array, which positions the Golgi in the centre of the cell, we have identified a role for microtubules that form at the Golgi membranes in a manner dependent on the microtubule regulators CLASPs.

Microtubule network asymmetry in motile cells: role of Golgi-derived array.

Cell migration requires polarization of the cell into the leading edge and the trailing edge. Microtubules (MTs) are indispensable for polarized cell migration in the majority of cell types. To support cell polarity, MT network has to be functionally and structurally asymmetric.

Asymmetric CLASP-dependent nucleation of noncentrosomal microtubules at the trans-Golgi network.

Proper organization of microtubule arrays is essential for intracellular trafficking and cell motility. It is generally assumed that most if not all microtubules in vertebrate somatic cells are formed by the centrosome. Here we demonstrate that a large number of microtubules in untreated human cells originate from the Golgi apparatus in a centrosome-independent manner.

Unsafe sex: do feelings matter?

The purpose of this study was to investigate the relationships among self-efficacy for condom use during distress (SE-Condom Distress), self-efficacy related to general HIV prevention skills (SE-HIV), and HIV risk behaviors, attitudes, and knowledge. Two hundred and twenty two adolescents with psychiatric disorders between 13 and 18 years-old participated. Participants completed measures related to HIV Self-Efficacy, HIV Attitudes, and Sexual Behaviors.

Repeat rape and multiple offending among undetected rapists.

Pooling data from four samples in which 1,882 men were assessed for acts of interpersonal violence, we report on 120 men whose self-reported acts met legal definitions of rape or attempted rape, but who were never prosecuted by criminal justice authorities. A majority of these undetected rapists were repeat rapists, and a majority also committed other acts of interpersonal violence. The repeat rapists averaged 5.
