#1
Bradford T Ulery, R Austin Hicklin, Maria Antonia Roberts, JoAnn Buscaglia
Exclusion is the determination by a latent print examiner that two friction ridge impressions did not originate from the same source. The concept and terminology of exclusion vary among agencies. Much of the literature on latent print examination focuses on individualization, and much less attention has been paid to exclusion. This experimental study assesses the associations between a variety of factors and exclusion determinations. Although erroneous exclusions are more likely to occur on some images and for some examiners, they were widely distributed among images and examiners...

Sorinel A Oprisan, Dave I Austin
We derived analytically and checked numerically a set of novel conditions for the existence and the stability of phase-locked modes in a biologically relevant master-slave neural network with a dynamic feedback loop. Since neural oscillators even in the three-neuron network investigated here receive multiple inputs per cycle, we generalized the concept of phase resetting to accommodate multiple inputs per cycle. We proved that the phase resetting produced by two or more stimuli per cycle can be recursively computed from the traditional, single stimulus, phase resetting...

Proprotein convertase subtilisin/kexin type 9 (PCSK9) plays a key role in regulating the levels of plasma low-density lipoprotein cholesterol (LDL-C). Here, we demonstrate that the compound PF-06446846 inhibits translation of PCSK9 by inducing the ribosome to stall around codon 34, mediated by the sequence of the nascent chain within the exit tunnel. We further show that PF-06446846 reduces plasma PCSK9 and total cholesterol levels in rats following oral dosing. Using ribosome profiling, we demonstrate that PF-06446846 is highly selective for the inhibition of PCSK9 translation...

BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) is a low-to-intermediate grade cutaneous neoplasm with a low propensity for metastasis and a high rate of local recurrence. It typically presents as a dermal plaque or nodule on the trunk, limbs, or head and neck region. Vulvar DFSP has also been described, although it is less common. OBJECTIVE: To review the available literature and discuss the clinical course of DFSP affecting the vulva. MATERIALS AND METHODS: We reviewed the existing English-language literature on DFSP of the vulva with respect to clinical presentation, diagnosis, treatment, and outcome...

The objective of this study was to determine whether administration of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) prior to other neuropsychological testing improves performance on subsequent measures due to practice effects. Participants completed the RBANS and related neuropsychological measures of the same cognitive domain in one of two counterbalanced orders. A MANOVA and follow-up independent t-tests were used to examine whether or not completing one set of measures prior to the other was associated with score differences...

Austin G Hester, Stanley J Kogan
INTRODUCTION: Pediatric presentations of a prostatic utricle have received only scant attention. Though recognized with increased frequency in boys with hypospadias, little is described about their incidence and potential for morbidity in boys with normal external genitalia. METHODS: We initially reviewed a cohort of 64 patients with hypospadias seen over a 3-year period to determine the frequency of investigative lower urinary tract studies and utricle identification...

BACKGROUND: Despite the tremendous and long-standing success of total hip arthroplasty and total knee arthroplasty as treatments for end-stage arthritis, periprosthetic joint infection (PJI) remains a rare but feared complication of these procedures. METHODS: This review highlights some of the difficulties inherent to studying PJI. These include the difficulty in powering studies to capture this relatively uncommon complication, as well as the heterogeneity in clinical presentation and manifestations associated with the diagnosis and treatment of PJI...

REVIEW
Austin Y Shull, Chien-An A Hu, Yong Teng
Peptide-derived drug discovery has experienced a remarkable resurgence in the past decade since the failure of small-molecule modulators to effectively access the large binding surfaces of intracellular protein-protein interactions as well as "undruggable" residues of certain disease-driving proteins. However, the effectiveness of peptide-based cancer therapies is being questioned in light of declines in pharmaceutical R&D efficiency. As a model of whole organism, zebrafish provide a means to develop promising peptide and protein anticancer agents in an informative, cost-effective and time-efficient manner, which also allows for surveying mechanisms of drug action and optimization of drug delivery system...

PURPOSE: Gender nonconformity, that is, transgressing conventionally "masculine" vs. "feminine" characteristics, is often stigmatized. Stigmatization and discrimination are social stressors that raise risk of adverse mental and physical health outcomes and may drive health inequities. However, little is known about the relationship between such social stressors and health-related quality of life (HRQOL). This paper aimed to examine associations between perceived gender nonconformity and HRQOL in a cohort of U...

REVIEW
Evan Austin, Andrew Mamalis, Derek Ho, Jared Jagdeo
Invasive cutaneous melanoma is a growing health concern. Although surgical excision can effectively treat in situ tumors, use for metastatic melanoma is limited. Laser and light-based therapies may be a valuable palliative treatment option for patients with stage III and stage IV cutaneous metastatic melanoma. Our goal is to review the published literature and provide evidence-based recommendations on laser and light-based palliative therapies for metastatic melanoma. A search of the databases Pubmed, EMBASE, Web of Science, and CINAHL was performed on March 10, 2016...

Tardigrades are microscopic animals that survive a remarkable array of stresses, including desiccation. How tardigrades survive desiccation has remained a mystery for more than 250 years. Trehalose, a disaccharide essential for several organisms to survive drying, is detected at low levels or not at all in some tardigrade species, indicating that tardigrades possess potentially novel mechanisms for surviving desiccation. Here we show that tardigrade-specific intrinsically disordered proteins (TDPs) are essential for desiccation tolerance...

The most commonly used method for the formation of well-defined iron and iron-containing heterometallic nanoparticles is the thermal decomposition of iron pentacarbonyl (Fe(CO)5). However, iron pentacarbonyl is highly toxic and volatile, which introduces safety concerns and drastically diminishes control over the reaction stoichiometry. Here we alleviate these issues by beginning with an easy-to-handle solid, triiron dodecacarbonyl (Fe3(CO)12). The issue of poor solubility of this cluster is addressed by its reaction with amine, which renders the cluster fully soluble in common high boiling point solvents...

Austin Cole, John L Hiatt, Christopher Arnold, Terry Sites, Ramon Ylanon
BACKGROUND: Chronic exertional compartment syndrome (CECS) is a recognized condition in the lower limb, with many reports in the literature. However, very few instances include CECS of the upper limb. This article presents the case of a collegiate softball pitcher presenting with CECS in her right forearm. To our knowledge, this is the first case report of a softball player with CECS, with only one similar incident in a major league baseball player. PURPOSE: The rarity of this condition normally places it low on the differential diagnosis...

Diabetic cardiomyopathy is preceded by mitochondrial alterations, and progresses to heart failure. We studied whether treatment with methylene blue (MB), a compound that was reported to serve as an alternate electron carrier within the mitochondrial electron transport chain (ETC), improves mitochondrial metabolism and cardiac function in type 1 diabetes. MB was administered at 10 mg/kg/day to control and diabetic rats. Both echocardiography and hemodynamic studies were performed to assess cardiac function...

BACKGROUND: In 2010, South Africa's National Department of Health launched a national primary health care (PHC) initiative to strengthen health promotion, disease prevention, and early disease detection. The strategy, called Re-engineering Primary Health Care (rPHC), aims to provide a preventive and health-promoting community-based PHC model. A key component of rPHC is the use of community-based outreach teams staffed by generalist community health workers (CHWs). METHODS: We conducted focus group discussions and surveys on the knowledge and attitudes of 91 CHWs working on community-based rPHC teams in the King Sabata Dalindyebo (KSD) sub-district of Eastern Cape Province...

Without a glucocorticoid (GC) ligand, the transcription factor glucocorticoid receptor (GR) is largely cytoplasmic, with its GC-binding domain held in high affinity conformation by a cluster of chaperones. Binding a GC causes serial dis- and re-associations with chaperones, translocation of the GR to the nucleus, where it binds to DNA sites and associates with coregulatory proteins and basic transcription complexes. Herein, we describe the effects of a potent protective osmolyte, trimethylamine N-oxide (TMAO), on a conditions-dependent "activation-labile" mutant GR (GRact/l), which under GR-activating conditions cannot bind GCs in cells or in cell cytosols...

In Alzheimer Disease (AD), non-verbal skills often remain intact for far longer than verbally mediated processes. Four (1 female, 3 males) participants with early-stage Clinically Diagnosed Dementia of the Alzheimer Type (CDDAT) and eight neurotypicals (NTs; 4 females, 4 males) completed the emotional valence determination test (EVDT) while undergoing BOLD functional magnetic resonance imaging (fMRI). We expected CDDAT participants to perform just as well as NTs on the EVDT, and to display increased activity within the bilateral amygdala and right anterior cingulate cortex (r-ACC)...

A heterozygous Caveolin-1 c.474delA mutation has been identified in a family with heritable pulmonary arterial hypertension (PAH). This frameshift mutation leads to caveolin-1 protein that contains all known functional domains but has a change only in the final 20 amino acids of the C terminus. Here we studied how this mutation alters caveolin-1 function using patient-derived fibroblasts. Transmission electron microscopy showed that fibroblasts carrying the c.474delA mutation formed typical caveolae. Expression of mutated caveolin-1 in caveolin-1-null mouse fibroblasts failed to induce formation of caveolae due to retention of the mutated protein in the endoplasmic reticulum...
