When we do not know a language, we are at the mercy of an interpreter. The same is true for research: Special Operations Forces (SOF) clinicians not actively involved in research initiatives may rely on scientific interpreters, so it is important to speak some of the language personally. For any clinician, using evidence in practice requires a working knowledge of how that evidence was generated from research, which requires an understanding of research science language. Here we review common basics of research science to reinforce concepts and elements of experimental and nonexperimental research...

Live bird markets are common in certain regions of the U.S. and in other regions of the world. We experimentally tested the ability of a wild bird influenza A virus to transmit from index animals to naïve animals at varying animal densities in stacked cages in a simulated live bird market. Two and six mallards, five and twelve quail, and six and nine pheasants were used in the low-density and high-density stacks of cages, respectively. Transmission did not occur in the high-density stack of cages likely due to the short duration and relatively low levels of shedding, a dominance of oral shedding, and the lack of transmission to other mallards in the index cage...

The diagnosis ileus is one of the most common indications for an emergency laparotomy. In 70% of the cases, the small intestine is affected, and in 30% it is the colorectum. While stuck hernias are a major cause in developing countries, the most common causes in western countries are postoperative adhesions that lead to an acute bowl obstruction. The timeframe for treatment of a complete mechanical obstruction is short as acute ischemia can lead to necrosis with bowl perforation within 6 h. The perioperative lethality for an emergency laparotomy due to an ileus ranges from 5-15%...

Automated left ventricular (LV) segmentation is crucial for efficient quantification of cardiac function and morphology to aid subsequent management of cardiac pathologies. In this paper, we parameterize the complete (all short axis slices and phases) LV segmentation task in terms of the radial distances between the LV centerpoint and the endo- and epicardial contours in polar space. We then utilize convolutional neural network regression to infer these parameters. Utilizing parameter regression, as opposed to conventional pixel classification, allows the network to inherently reflect domain-specific physical constraints...

Carbon nanomaterials have been used to treat neurodegenerative diseases and neural disorders due to their diverse molecular structures. Corannulene is a three-dimensional π-bowl carbon nanomaterial that is different from planar PAHs, fullerenes and carbon nanotubes, but little is known about its biological functions. Herein, corannulene was functionalized with mPEG-DESP to prepare PEGylation corannulene nanoparticles (PEGylation CoNps). The synthesized PEGylation CoNps shows enhanced solubility and reduced aggregation when compared corannulene...

Phosphoinositide-3-kinase and protein kinase B (PI3K-AKT) is upregulated in multiple myeloma (MM). Using a combination of short hairpin RNA (shRNA) lentivirus-mediated knockdown and pharmacologic isoform-specific inhibition we investigated the role of the PI3K p110γ (PI3Kγ) subunit in regulating MM proliferation and bone marrow microenvironment-induced MM interactions. We compared this with inhibition of the PI3K p110δ (PI3kδ) subunit and with combined PI3kδ/γ dual inhibition. We found that MM cell adhesion and migration were PI3Kγ-specific functions, with PI3kδ inhibition having no effect in MM adhesion or migration assays...

Using an automated cell counting technique developed previously (Case et al., Ecology and Evolution 2014; 4: 3494), we explore the lifespan effects of lac-1, a ceramide synthase gene paralogous to lag-1 in Neurospora crassa in conjunction with the band bd (ras-1) gene. We find that the replicative lifespan of a lac-1(KO)bd double mutants is short, about one race tube cycle, and this double mutant lacks a strong ~21-hr clock cycle as shown by race tube and fluorometer analysis of fluorescent strains including lac-1(KO) ...

OBJECTIVE: To examine whether older age was associated with lower health-related quality of life (HRQOL) among patients with systemic lupus erythematosus (SLE) and whether differential disease-related damage and activity explained these associations. METHODS: We used cross-sectional data on 684 patients with SLE aged ≥20 years from the Georgians Organized Against Lupus cohort to estimate the associations between age (categorised as 20-39, 40-59 and ≥60 years) and HRQOL (Short Form-12 norm-based domain and physical component summary (PCS) and mental component summary (MCS) scores), using multivariable linear regression...

INTRODUCTION: Acute latissimus dorsi tendon injuries are uncommon, having not previously been described in cricketers. The leg spinner's stock ball bowling technique and the fast bowler's back-of-the-hand slow ball, which is used much more widely in T20 cricket, produce a significant eccentric contraction load on the latissimus dorsi muscle. METHODOLOGY: A retrospective review of a case series of acute latissimus dorsi tendon injuries in 3 elite cricketers (2 fast bowlers and a leg-spin bowler)...

INTRODUCTION: Isolated coracoid fractures are rare and few scattered cases are reported in literature. Coracoid fractures can be missed and the treatment for coracoid process fractures is still controversial. The case presented here is of an isolated coracoid process fracture which was treated surgically. CASE REPORT: A 15-years old male presented after 4 days of injury complaining of persistent pain in the right shoulder following a jerk during bowling. Physical examination revealed tenderness in the left shoulder...

The solid, central part of a comet--its nucleus--is subject to destructive processes, which cause nuclei to split at a rate of about 0.01 per year per comet. These destructive events are due to a range of possible thermophysical effects; however, the geophysical expressions of these effects are unknown. Separately, over two-thirds of comet nuclei that have been imaged at high resolution show bilobate shapes, including the nucleus of comet 67P/Churyumov-Gerasimenko (67P), visited by the Rosetta spacecraft. Analysis of the Rosetta observations suggests that 67P's components were brought together at low speed after their separate formation...

Cricket is a popular international team sport with various game formats ranging from long-duration multiday tests to short-duration Twenty20 game play. The role of batsmen is critical to all game formats, with differing physiological demands imposed during each format. Investigation of the physiological demands imposed during cricket batting has historically been neglected, with much of the research focusing on bowling responses and batting technique. A greater understanding of the physiological demands of the batting role in cricket is required to assist strength and conditioning professionals and coaches with the design of training plans, recovery protocols, and player-management strategies...

We have investigated the electronic and charge transport properties of two regioisomeric contorted polyaromatic hydrocarbons at the molecular level as well as in the crystalline state. Electron and hole transport is studied on the basis of an incoherent charge hopping model through DFT calculations. For trifluro-dibenzoperylene (CF3-DBP, ), which crystallizes as a herringbone network, the computed drift hole and electron mobilities are 0.234 and 0.008 cm(2) V(-1) S(-1), respectively. The greater hole mobility in the DBP crystal (μh/μe = 29) can be rationalized by its lower hole reorganization energy and higher hole transfer integral simultaneously...

BACKGROUND: Antihypertensive medication use has been associated with an increased risk of falls in some but not all studies. Few data are available on the short-term risk of falls after antihypertensive medication initiation and intensification. METHODS AND RESULTS: We examined the association between initiating and intensifying antihypertensive medication and serious fall injuries in a case-crossover study of 90 127 Medicare beneficiaries who were ≥65 years old and had a serious fall injury between July 1, 2007, and December 31, 2012, based on emergency department and inpatient claims...

A short-cut review was carried out to establish whether cardiac compressions are beneficial in children in traumatic cardiac arrest. Forty-eight unique papers were found using the reported searches but none were relevant to the clinical question. It is concluded that there is no evidence available to answer the question posed and that local guidelines should be followed.

Shape-persistent macrocycles are attractive functional targets for synthesis, molecular recognition, and hierarchical self-assembly. Such macrocycles are noncollapsible and geometrically well-defined, and they are traditionally characterized by having repeat units and low conformational flexibility. Here, we find it necessary to refine these ideas in the face of highly flexible yet shape-persistent macrocycles. A molecule is shape-persistent if it has a small change in shape when perturbed by external stimuli (e...
