BACKGROUND: Atypical pituitary adenomas (APAs) are a subset of pituitary adenomas (PAs) characterized by the 2004 World Health Organization (WHO) guidelines to have higher risk histopathological features than typical PAs. In July 2017, the WHO published an update to their classification of pituitary tumors and abandoned the APA terminology. OBJECTIVE: To assess the prevalence and outcomes of patients diagnosed with APA through a literature review. Focus was placed on variation in the application of the previous WHO criteria and on rates of recurrence...

The number of patients with adrenal aldosterone-producing adenomas (APAs) has gradually increased. However, even after adenoma resection, some patients still suffer from high systolic blood pressure (SBP), which is possibly due to great arterial remodeling. Moreover, mineralocorticoid receptors (MRs) were found to be expressed in vascular smooth muscle cells (VSMCs). This study aims to determine whether MR antagonism protects the aorta from aldosterone-induced aortic remolding. Male rats were subcutaneously implanted with an osmotic minipumps and randomly divided into four groups: control; aldosterone (1 μg/h); aldosterone plus a specific MR antagonist, eplerenone (100 mg/kg/day); and aldosterone plus a vasodilator, hydralazine (25 mg/kg/day)...

Auxin is widely involved in plant growth and development. However, the molecular mechanism on how auxin carries out this work is unclear. In particular, impact of auxin on pre-mRNA posttranscriptional regulation is mostly unknown. By using a poly(A) tag (PAT) sequencing approach, mRNA alternative polyadenylation (APA) profiles after auxin treatment were revealed. We showed that hundreds of poly(A) site clusters (PACs) are affected by auxin at the transcriptome level, where auxin reduces PAC distribution in 5'UTR, but increases in 3'UTR...

Teacher-directed violence is a common, yet understudied, phenomenon. Perpetrators of violence against teachers include not just students, but also administrators, parents, and colleagues. Administrators are key stakeholders when it comes to shaping school climate and safety that can reduce or increase the negative impact of violence against teachers. In this study, 237 teachers' qualitative responses from a larger sample of 2,431 anonymous, online survey responses were examined to better understand their experiences with incidents of violence and how administrators played a role in these experiences...

Depersonalization (DP) is a dissociative phenomenon, characterised by feeling "unreal" or detached from one's own emotions, thoughts and behaviour (APA, 2013). It is considered a defense mechanism, employed in response to overwhelming events, whereby thoughts and emotions are suppressed in order to enhance the individual's' capacity to function in traumatic environments. DP has been found to co-occur with anxiety and depressive disorders and childhood emotional maltreatment (EM) has been identified as an important predisposing factor...

Objective: To investigate the role of adrenal vein sampling (AVS) in identifying the subtype of primary aldosteronism (PA). Methods: AVS was performed in 50 patients who were confirmed as PA between September 2010 and September 2016 in Nanjing Drum Tower Hospital. Clinical, biochemical and follow-up data were reviewed retrospectively. Bilaterally simultaneous catheterization without cosyntropin stimulation and contemporaneous cortisol measurement during AVS were used. Selectivity index (SI)≥1.5 suggested that the sample was from the adrenal vein...

Previous studies have shown that the prognosis of lung adenocarcinoma is associated with pathological characterization. In this study, we investigated whether pathology-based prognosis was further influenced by both tumor stage and oncogenic driver mutations. To this end, we recruited a cohort of 465 lung adenocarcinoma patients in China. These patients were classified into 6 pathology-defined subtypes i.e., lepidic-predominant adenocarcinoma (LPA), acinar-predominant adenocarcinoma (APA), papillary-predominant adenocarcinoma (PPA), micropapillary-predominant adenocarcinoma (MPA), solid-predominant adenocarcinoma (SPA), and invasive mucinous adenocarcinoma (IMA)...

The focus of this paper is the investigation of reduced graphene oxide (GO)/nickel foam (RGON) samples for use as supercapacitor electrodes. Nickel foam samples were soaked in a GO suspension and dried before being subjected to two different methods to remove oxygen. Atmospheric pressure annealed (APA) samples were treated with a varying number (10-18) of nitrogen plasma jet scans, where sample temperatures did not exceed 280 °C. Furnace annealed (FA) samples were processed in an atmosphere of hydrogen and argon, at temperatures ranging from 600 °C to 900 °C...

RNAi therapeutics carried a great promise to the area of personalized medicine: the ability to target "undruggable" oncogenic pathways. Nevertheless, their efficient tumor targeting via systemic administration had not been resolved yet. Amphiphilic alkylated poly(α)glutamate amine (APA) can serve as a cationic carrier to the negatively-charged oligonucleotides. APA polymers complexed with siRNA to form round-shaped, homogenous and reproducible nano-sized polyplexes bearing ~50nm size and slightly negative charge...

REVIEW
L Michael Bowen, Brett Williams, Luke Stanke
Background: Professionalism is a pillar of paramedicine. Internationally paramedic curricula emphasize valid assessment of three domains: cognitive, psychomotor, and affective domains (professionalism). Little is reported on competency measures for professionalism specific to paramedicine. Literature suggests that paramedic students, paramedic practitioners, medical directors, and patients believe that professional attributes should have an increased focus. Objective: The objective of this scoping review is to outline valid and reliable assessments that evaluate professional behaviors...

: Antiplatelet agents (APA) are considered first-line therapy in preventing cardiovascular thrombotic events, but they are of limited value in the prophylaxis of venous thromboembolism (VTE) during the perioperative period. Consequently, many patients should receive both an APA and an anticoagulant. This combination can increase the bleeding risk and it is necessary to make some recommendations to minimise that risk. In patients receiving APA chronically, if the risk of VTE outweighs the risk of bleeding, we suggest pharmacological prophylaxis (grade 2C)...

Aldosterone production is initiated by angiotensin II stimulation and activation of intracellular Ca(2+) signaling. In aldosterone-producing adenoma (APA) cells, the activation of intracellular Ca(2+) signaling is independent of the renin-angiotensin-aldosterone systems. The purpose of our study was to clarify molecular mechanisms of aldosterone production related to Ca(2+) signaling. Transcriptome analysis revealed that the CALN1 gene encoding calneuron 1 had the strongest correlation with CYP11B2 (aldosterone synthase) among genes encoding Ca(2+)-binding proteins in APA...

Background: Alternative polyadenylation (APA) is emerging as a major post-transcriptional mechanism for gene regulation, and dysregulation of APA contributes to several human diseases. However, the functional consequences of APA in human cancer are not fully understood. Particularly, there is no large-scale analysis in cancer cell lines. Methods: We characterized the global APA profiles of 6398 patient samples across 17 cancer types from The Cancer Genome Atlas and 739 cancer cell lines from the Cancer Cell Line Encyclopedia...
