BACKGROUND: Pulmonary infiltrates (PIs) detected in patients with non-Hodgkin lymphoma (NHL) may present a diagnostic challenge due to their wide differential diagnosis, including infection, pulmonary lymphoma and immunochemotherapy-associated pulmonary toxicity. OBJECTIVES: To characterize therapy-associated PIs by positron emission tomography/computed tomography (PET/CT) imaging. METHODS: We conducted a historical analysis of fluorodeoxyglucose-PET/CT (18F-FDG-PET/CT) PIs in NHL patients treated with combined immunochemotherapy including rituximab...

Compared to normal cells, cancer cells have a unique metabolism by performing lactic acid fermentation in the presence of oxygen, also known as the Warburg effect. Researchers have proposed several hypotheses to elucidate the phenomenon, but the mechanism is still an enigma. In this review, we discuss three typical models, such as "damaged mitochondria", "adaptation to hypoxia", and "cell proliferation requirement", as well as contributions from mass spectrometry analysis toward our understanding of the Warburg effect...

Insufficient temporal monitoring of water quality in streams or engineered drains alters the apparent shape of storm chemographs, resulting in shifted model parameterisations and changed interpretations of solute sources that have produced episodes of poor water quality. This so-called 'aliasing' phenomenon is poorly recognised in water research. Using advances in in-situ sensor technology it is now possible to monitor sufficiently frequently to avoid the onset of aliasing. A systems modelling procedure is presented allowing objective identification of sampling rates needed to avoid aliasing within strongly rainfall-driven chemical dynamics...

OBJECTIVE: Soprano singers face a number of specific challenges when singing vowels at high frequencies, due to the wide spacing of harmonics in the voice source. The varied and complex techniques used to overcome these are still not fully understood. Magnetic resonance imaging (MRI) has become increasingly popular in recent years for singing voice analysis. This study proposes a new protocol using three-dimensional MRI to investigate the articulatory parameters relevant to resonance tuning, a technique whereby singers alter their vocal tract to shift its resonances nearer to a voice source harmonic, increasing the amplitude of the sound produced...

REVIEW
David C Spray, Menachem Hanani
Enhanced expression and function of gap junctions and pannexin (Panx) channels has been associated with both peripheral and central mechanisms of pain sensitization. At the level of the sensory ganglia, evidence includes augmented gap junction and pannexin1 expression in glial cells and neurons in inflammatory and neuropathic pain models and increased synchrony and enhanced cross-excitation among sensory neurons by gap junction-mediated coupling. In spinal cord and in suprapinal areas, evidence is largely limited to increased expression of relevant proteins, although in several rodent pain models, hypersensitivity is reduced by treatment with gap junction/Panx1 channel blocking compounds...

BACKGROUND: Intimate partner physical violence is a common global phenomenon. About 30.00% and 38.83% of women in the world and in sub-Saharan Africa experienced physical violence by their partner respectively in 2013. Though intimate partner violence has serious adverse health consequences, there is limited information about partner violence during pregnancy in Ethiopia. Therefore, the aim of this study was to assess the prevalnce of physical intimate partner violence during pregnancy and associated factors among women attending antenatal care in Shire Endaselassie town, Tigray, northen Ethiopia METHODS: A facility based cross-sectional study was conducted from May 3 to July 6, 2015...

BACKGROUND: Haematuria and pelvic pain are recognized and documented adverse reactions related to Cabazitaxel use. To date there has not been any documentation of imaging findings in patients with this presentation. CASES: We report a case series of five patients who experienced these symptoms while on Cabazitaxel and were all found to have very similar urothelial changes on CT. The patients were noted to have ureteric and renal pelvic dilatation along with urothelial enhancement (in those who had post contrast imaging)...

BACKGROUND: The impact of illness labels on the stigma experiences of individuals with mental health problems is a matter of ongoing debate. Some argue that labels have a negative influence on judgments and should be avoided in favour of information emphasising the existence of a continuum of mental health/illness. Others believe that behavioral symptoms are more powerful influencers of stigma than labels. The phenomenon has received little attention in adolescent research, despite the critical importance of the peer group at this developmental stage...

The aggregation-induced emission (AIE) phenomenon of the metal nanoclusters (NCs) has been discovered quite recently, which is considered to be creative to improve the optical properties of NCs upon ligand aggregation. In the present study, we report an AIE system for double-stranded DNA-templated silver nanoclusters (AgNCs-dsDNA) by using bovine serum albumin (BSA) in solution, which induce a moderate emission enhancement of AgNCs (5-fold) and a blue-shift through a loosen interaction. In addition, significant luminescence enhancement (30-fold) is further stimulated by the addition of digestive enzyme to the system by altering the surface structure of the aggregated particles...

Blindsight patients with damage to the visual cortex can discriminate objects but report no conscious visual experience. This provides an intriguing opportunity to allow the study of subjective awareness in isolation from objective performance capacity. However, blindsight is rare, so one promising way to induce the effect in neurologically intact observers is to apply transcranial magnetic stimulation (TMS) to the visual cortex. Here, we used a recently-developed criterion-free method to conclusively rule out an important alternative interpretation of TMS-induced performance without awareness: that TMS-induced blindsight may be just due to conservative reporting biases for conscious perception...

Pain is a subjective and complex phenomenon. Its complexity is related to its heterogeneity: multiple component processes, including sensation, affect, and cognition, contribute to pain experience and reporting. These components are likely to be encoded in distributed brain networks that interact to create pain experience and pain-related decision-making. Therefore, to understand pain, we must identify these networks and build models of these interactions that yield testable predictions about pain-related outcomes...

The liver and kidneys are often similarly affected by a single disease. This is the case in metabolic, immunological, toxic, and infectious diseases, and in the different congenital malformation syndromes. Also, an enzymatic defect in an otherwise healthy liver or the consequences of advanced liver disease by itself can cause kidney disease as a secondary phenomenon. In this review, we describe numerous pathogenic mechanisms leading to dysfunction or malformations of the liver and kidneys in children. We encourage multidisciplinary management for optimal care...

INTRODUCTION: Some patients travel out of, while others come into Africa for medical care through a growing global phenomenon referred to as medical tourism (MT): the travel in search of medical care that is either unavailable, unaffordable or proscribed at home healthcare systems. While some castigate MT as promoting healthcare inequity, others endorse it as a revenue generator, promising local healthcare system strengthening. Currently, however, the understanding of this component of healthcare in Africa is inadequate...

Myocardial infarction is the global leading cause of mortality (Go AS et al. 2014). Coronary artery occlusion is its main etiology and it is commonly treated by Coronary Artery Bypass Graft (CABG) surgery (Wilson CT 2007). The long-term outcome remains unsatisfactory (Benedetto U 2016). The vein faces the phenomenon of restenosis during the post-surgery, which consists of re-occlusion of the lumen and usually requires secondary intervention even within one year after the initial surgery (Harskamp RE 2013). We propose an extensive study of the restenosis phenomenon by implementing two mathematical models previously developed: a heuristic Dynamical System (DS) (Garbey M and Berceli SA 2013), and a stochastic Agent Based Model (ABM) (Garbey M et al...

Cancer chemotherapy failure is often due to the overexpression of ATP-binding cassette (ABC) transporters (particularly ABCB1), resulting in a variety of structurally and pharmacologically unrelated drugs efflux. The multidrug resistance (MDR) phenomenon could be reversed by ABCB1 inhibitors. Now, JL-A7 as the lead compound based on a triazol-N-ethyl-tetrahydroisoquinoline scaffold, 18 compounds were designed and synthesized. Substitution in para positions yielded high activities toward ABCB1. Moreover, compound 5 could effectively block the drug efflux function of ABCB1 and increase the accumulation of anti-cancer drugs to achieve effective treatment concentration in MDR cells...

PURPOSE: Given the high levels of obesity among U.S. children, we examine whether obesity in childhood is a passing phenomenon or remains entrenched into adolescence. METHODS: Data are from the prospective nationally representative Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (analytic sample = 6600). Anthropometrics were measured six times during 1998-2007. Overweight and obesity were defined using CDC cut-points. Entrenched obesity was defined as obesity between ages 5-9 coupled with persistent obesity at ages 11 and 14...

BACKGROUND: We have identified a cause of falsely elevated parathyroid hormone (PTH) levels after total parathyroidectomy with forearm auto-transplantation (TPT-ATx). Our cases highlight the need to draw PTH samples remotely, away from forearm graft sites, to ensure accurate levels. CASE PRESENTATIONS: We report on four patients who were referred to our surgical team at an academic tertiary care center for what was perceived to be recurrent hyperparathyroidism 2-5 years following total parathyroidectomy with auto-transplantation...

Cooperative breeding, in which more than a pair of conspecifics cooperate to raise young at a single nest or brood, is widespread among vertebrates but highly variable in its geographic distribution. Particularly vexing has been identifying the ecological correlates of this phenomenon, which has been suggested to be favored in populations inhabiting both relatively stable, productive environments and in populations living under highly variable and unpredictable conditions. Griesser et al. provide a novel approach to this problem, performing a phylogenetic analysis indicating that family living is an intermediate step between nonsocial and cooperative breeding birds...
