INTRODUCTION: Methicillin-resistant Staphylococcus aureus (MRSA) is globally recognized as an important public health problem. Whereas comprehensive molecular typing data of MRSA strains is available, particularly in Europe, North America and Australia, similar information is very limited in sub-Saharan Africa including Zambia. METHODS: In this study, thirty two clinical isolates of Staphylococcus aureus, collected at a large referral hospital in Lusaka, Zambia between June 2009 and December 2012 were analysed by Staphylococcal cassette chromosome mec (SCCmec), Staphylococcus protein A gene typing (spa) and detection of the Panton-Valentine Leukocidin genes (pvl)...

Giant amphiphiles encompassing a hydrophilic β-cyclodextrin (βCD) component and a hydrophobic calix[4]arene (CA4) module undergo self-assembly in aqueous media to afford core-shell nanospheres or nanocapsules, depending on the nanoprecipitation protocol, with high docetaxel (DTX) loading capacity. The blank and loaded nanoparticles have been fully characterized by dynamic light scattering (DLS), ζ-potential measurements and cryo-transmission electron microscopy (cryo-TEM). The data are compatible with the distribution of the drug between the nanoparticle core and the shell, where it is probably anchored by inclusion of the DTX aromatic moieties in βCD cavities...

INTRODUCTION: Hydrocephalus represents impairment in cerebrospinal fluid (CSF) dynamics. If the treatment of hydrocephalus is considered difficult, the repeated revisions of ventriculo-peritoneal (VP) shunts are even more challenging. OBJECTIVE: The aim of this article is to evaluate the efficiency of ventriculo-epiplooic (VEp) shunt as a feasible alternative in hydrocephalic patients. MATERIAL AND METHODS: A technical modification regarding the insertion of peritoneal catheter was imagined: midline laparotomy 8-10cm long was performed in order to open the peritoneal cavity; the great omentum was dissected between its two layers; we placed the distal end of the catheter between the two epiplooic layers; a fenestration of 4cm in diameter into the visceral layer was also performed...

PURPOSE: Knowledge of the psychological distress of long- and very long-term (>10 years) prostate cancer (PC) survivors is limited. This study intended to examine the parameters influencing anxiety related to prostate-specific antigen (PSA) and PC in long-term survivors after radical prostatectomy. METHODS: We surveyed 4719 PC survivors from the German multicenter prospective database "Familial Prostate Cancer." We evaluated the association of PC-related anxiety (MAX-PC) with sociodemographic characteristics, family history of PC, global health status/quality of life (EORTC QLQ-C30), depression and anxiety (PHQ-2; GAD-2), latest PSA level, time since radical prostatectomy, and current therapy...

In today's market, every product seems to be marked by the label of "experience". It is expected that successful products give the consumer "extraordinary experiences". The research in consumption experience is growing, but much work still needs to be done to understand the food and beverage experience. A qualitative study was conducted using contextual focus groups to explore the building blocks of consumers' drinking experience of industrial and craft beers. The results show that drinking experience is shaped by our cognitive, sensory or affective systems, especially during the core consumption experience...

AMP-activated protein kinase (AMPK) is an enzyme crucial in cellular metabolism found to be inhibited in many metabolic diseases including type 2 diabetes. Thiazolidinediones (TZDs) are a class of anti-diabetic drug known to activate AMPK through increased phosphorylation at Thr(172), however there has been no research to date on whether they have any effect on inhibition of AMPK's lesser known site of inhibition, Ser(485/491). HepG2 cells were treated with troglitazone and phosphorylation of AMPK was found to increase at both Thr(172) and Ser(485) in a dose- and time-dependent manner...

Squamous cell carcinoma (SCC) in situ or Bowen's disease (BD) is a slowly progressive malignancy. However, cases of regression have been reported. Recent reviews cover only certain aspects of this disease; therefore, this paper's aim is to cover all the relevant aspects for medical practice, such as clinical, histological and therapeutic details. BD may affect all regions of the skin and mucosa, but in accordance with the region and etiologic factor, it may embrace different clinical forms, some of them very similar with other skin lesions...

One of the major and essential classes of transmembrane (TM) receptors, present in all domains of life, is sensor histidine kinases (HKs), parts of two-component signaling systems (TCS). The structural mechanisms of transmembrane signaling by these sensors are poorly understood. We present here crystal structures of the periplasmic sensor domain, the TM domain and the cytoplasmic HAMP domain of the Escherichia coli nitrate/nitrite sensor HK NarQ in the ligand-bound and mutated ligand-free states. The structures reveal that the ligand binding induces significant rearrangements and piston-like shifts of TM helices...

BACKGROUND AND AIMS: Chronic low-grade inflammation is involved in the development of metabolic disorders including atherosclerosis, type 2 diabetes (T2D) and metabolic syndrome. Aerobic exercise has been shown to be anti-inflammatory and attenuate postprandial blood lipids, however, the effect of exercise on postprandial inflammation remains unclear. The aim of this study was to determine the protective effect of a single bout of aerobic exercise against postprandial lipemia and peripheral blood mononuclear cell (PBMC) inflammation and to evaluate associations with changes in the energy-sensing enzyme, AMP-activated protein kinase (AMPK)...

INTRODUCTION: Strong scientific evidence supports voluntary medical male circumcision as part of an overall HIV prevention strategy, but self-report information on circumcision status may be inaccurate. The study objectives were to obtain estimates of male circumcision within the Rwanda Defense Force (RDF), to assess the ability of soldiers to correctly report their own circumcision status, and to document the uptake of voluntary medical male circumcision (VMMC) in the RDF. METHODS: Data were collected from members of the Rwandan military during their annual physical examination...

Our previous studies reported that one of the main mechanisms of the antitumor activity of simvastatin (SIM) in B16.F10 murine melanoma cells was associated with strong suppression of the constitutive cell production of the α subunit of the heterodimeric transcription factor hypoxia-inducible factor (HIF)-1. Thus, the present study aimed to broaden this finding under hypoxic conditions induced by incubation of B16.F10 cells with cobalt chloride, when the constitutive production of HIF-1α in these melanoma cells is amplified by inducible expression of this factor...

Quantum systems can be characterized by their correlations. Higher-order (larger than second order) correlations, and the ways in which they can be decomposed into correlations of lower order, provide important information about the system, its structure, its interactions and its complexity. The measurement of such correlation functions is therefore an essential tool for reading, verifying and characterizing quantum simulations. Although higher-order correlation functions are frequently used in theoretical calculations, so far mainly correlations up to second order have been studied experimentally...

Staphylococcus aureus MRSA strains belonging to the clonal complex 398 (CC398) are highly prevalent in livestock and companion animals but may also cause serious infections in humans. CC398 strains in livestock usually do not possess well-known virulence factors that can be frequently found in other MRSA sequence types (ST). Since many staphylococcal virulence genes are residing on the genomes of temperate phages, the question arises why livestock-associated (LA-) CC398 strains are only rarely infected by those phages...

Introduction It has been shown that brain ultrasonography (US) is an efficient tool for improving three-dimensional (3D) spatial orientation during neurosurgical interventions. However, it necessitates specific training as it is highly operator-dependent. To date, neurosurgeons have relied solely on intraoperative practice to improve their mastery of brain US; this has obvious limitations. Herein, we consider whether a study of brain US on human cadavers could enable a training platform for neurosurgeons and residents to be developed...

Manganese-containing BEA zeolites, MnxSiBEA (x = 1-4 wt%) and Mn(I.E.)AlBEA, were prepared by a two-step post-synthesis method and a conventional wet ion-exchange, respectively, and applied as catalysts in the selective catalytic reduction of NO with ammonia (NH3-SCR). The physicochemical analysis of zeolite properties by high-energy-resolution fluorescence-detected XANES (HERFD-XANES) and X-ray emission spectroscopy (XES) uncovered that the coordination, geometry and oxidation state of Mn species are strongly related to the preparation method...
