Position Paper From the Association of Pathology Chairs: Assessing Autopsy Competency in Pathology Residency Training
(2018-12-10)Declining numbers of hospital autopsies performed in US pathology residency training programs and perceived declining practice of autopsy by many pathologists has caused stakeholder organizations to reassess the role of ... -
Position Paper From the Association of Pathology Chairs: Surgical Pathology Residency Training
(2018-12-10)Training in surgical pathology specimen dissection and microscopic diagnosis is an integral part of pathology residency training, as surgical pathology is one of the defining activities of most pathologists. The Accreditation ... -
Positive mRNA Translational Control in Germ Cells by Initiation Factor Selectivity
(2015)Ultimately, the production of new proteins in undetermined cells pushes them to new fates. Other proteins hold a stem cell in a mode of self-renewal. In germ cells, these decision-making proteins are produced largely from ... -
Post-transcriptional Gene Silencing Induced by Short Interfering RNAs in Cultured Transgenic Plant Cells
(2004-05)Short interfering RNA (siRNA) is widely used for studying post-transcriptional gene silencing and holds great promise as a tool for both identifying function of novel genes and validating drug targets. Two siRNA fragments ... -
Postpartum spontaneous dissection of the first obtuse marginal branch of the left circumflex coronary artery causing acute coronary syndrome: A case report and literature review
(2013-03-19)Spontaneous coronary artery dissection is a rare but important cause of acute coronary syndrome. It can cause unstable angina, acute myocardial infarction, and sudden death. The condition commonly affects young females ... -
Potential Mechanisms and Functions of Intermittent Neural Synchronization
(2017-05-30)Neural synchronization is believed to play an important role in different brain functions. Synchrony in cortical and subcortical circuits is frequently variable in time and not perfect. Few long intervals of desynchronized ... -
The potential role of magnetic resonance spectroscopy in image-guided radiotherapy
(2014-05-04)Magnetic resonance spectroscopy (MRS) is a non-invasive technique to detect metabolites within the normal and tumoral tissues. The ability of MRS to diagnose areas of high metabolic activity linked to tumor cell proliferation ... -
PP1 forms an active complex with TLRR (lrrc67), a putative PP1 regulatory subunit, during the early stages of spermiogenesis in mice
(2011-06)Mammalian spermatogenesis is a highly regulated developmental pathway that demands dramatic rearrangement of the cytoskeleton of the male germ cell. We have described previously a leucine rich repeat protein, TLRR (also ... -
Preclinical and Clinical Assessment of Cannabinoids as Anti-Cancer Agents
(2016-07)Cancer is the second leading cause of death in the United States with 1.7 million new cases estimated to be diagnosed in 2016. This disease remains a formidable clinical challenge and represents a substantial financial ... -
Preclinical evaluation of the PI3K/Akt/mTOR pathway in animal models of multiple sclerosis
(2018-01-03)The PI3K/AKT/mTOR pathway is an intracellular signalling pathway that regulates cell activation. proliferation, metabolism and apoptosis. Increasing body of data suggests that alterations in the PI3K/AKT/mTOR pathway may ... -
Predictors for Using a HIV Self-Test Among Migrant and Seasonal Farmworkers in North Carolina
(2015-07)Background: Approximately, two million migrant and seasonal farmworkers (MSF) work in the United States annually. Several factors, such as lack of access to healthcare services and health behaviors, contribute to risk of ... -
Predominant Expression of Hybrid N-Glycans Has Distinct Cellular Roles Relative to Complex and Oligomannose N-Glycans
(2016-06)Glycosylation modulates growth, maintenance, and stress signaling processes. Consequently, altered N-glycosylation is associated with reduced fitness and disease. Therefore, expanding our understanding of N-glycans in ... -
Premature Ovarian Insufficiency: Procreative Management and Preventive Strategies
(2018-12-28)Premature ovarian insufficiency (POI) is the loss of normal hormonal and reproductive function of ovaries in women before age 40 as the result of premature depletion of oocytes. The incidence of POI increases with age in ... -
Preparation and characterization of flax, hemp and sisal fiber-derived mesoporous activated carbon adsorbents
(2018-02-01)The first aim of this study was to investigate mesoporous activated carbon adsorbents from sisal, hemp, and flax fibers by cost-effective methods. Fibers were impregnated with low concentration (20 wt.%) phosphoric acid. ... -
Prevalence of coronary heart disease risk factors in physical education students
(2015)Abstract To establish the prevalence of coronary risk in physical education students, and compare risk between the genders and the years of course. We evaluated 246 physical education students using RISKO questionnaire to ... -

Prevalence, trends, outcomes, and disparities in hospitalizations for nonalcoholic fatty liver disease in the United States
(2019-07-17)Background: As the frequency of nonalcoholic fatty liver disease (NAFLD) continues to rise in the United States (US) community, more patients are hospitalized with NAFLD. However, data on the prevalence and outcomes of ... -
Preventable hospital admissions among the homeless in California: A retrospective analysis of care for ambulatory care sensitive conditions
(2014-10)Background: Limited research exists that investigates hospital admissions for ambulatory care sensitive conditions (ACSCs) among the homeless, who frequently lack a usual source of care. This study profiled ACSC admissions ... -
Prey Responses to Predator Chemical Cues: Disentangling the Importance of the Number and Biomass of Prey Consumed
(2012-10)To effectively balance investment in predator defenses versus other traits, organisms must accurately assess predation risk. Chemical cues caused by predation events are indicators of risk for prey in a wide variety of ...
