Rotavirus (RV) is the most common cause of severe gastroenteritis in infants and young children worldwide. RV causes approximately half a million deaths each year among children aged <5 years. According to WHO estimates for 2008, there were approximately 10 to 50 deaths annually in young children due to rotavirus diarrhea in Georgia. The purpose of this study was to assess the knowledge, attitudes, and practices related to rotavirus diarrhea and the rotavirus vaccine among health care workers (HCWs). The National Center for Disease Control and Public Health (NCDC) conducted a cross-sectional survey of HCWs involved in the expanded program of immunization (EPI)...

A series of new Lycopodium alkaloids, namely 1-epi-malycorin A (1), 1-epi-17S-hydroxymalycorin A (2), 6α-hydroxyphlegmariurine A (3), 2S,4R-dihydroxyfawcettimine (4), and 16-hydroxylycodine (5), together with 24 known ones, have been isolated from the club moss Phlegmariurus henryi. The structures of the new compounds were determined by extensive spectroscopic analysis, including 1D and 2D NMR, as well as X-ray crystallographic analysis. Among them, the absolute configurations of 1, 2, and 4 and the structure of 3 were confirmed on the basis of the single-crystal X-ray crystallographic analysis...

BACKGROUND: Contraception helps to prevent unplanned pregnancies among human immune virus positive women. The contraceptive utilization status and associated factors were not well addressed in the study area. Therefore, this study aimed to assess utilization of contraceptives and associated factors among human immune virus positive reproductive age group women appearing at anti-retroviral therapy clinic at the University of Gondar Hospital, North West Ethiopia. METHOD: An institution based cross-sectional study was conducted among 397 systematically selected HIV positive reproductive age women who visited ART unit of the University of Gondar teaching referral hospital from January 8-20, 2014...

Antibiotic resistance is a major threat to human welfare. Inhibitors of multidrug efflux pumps (EPIs) are promising alternative therapeutics that could revive activities of antibiotics and reduce bacterial virulence. Identification of new druggable sites for inhibition is critical for development of effective EPIs, especially in light of constantly emerging resistance. Here, we describe EPIs that interact with periplasmic membrane fusion proteins, critical components of efflux pumps that are responsible for the activation of the transporter and the recruitment of the outer-membrane channel...

BACKGROUND: Neutrophilgelatinase-associated lipocalin (NGAL) has been proven to be a useful biomarker for early detection of acute kidney injury, but it is not known whether adding NGAL measurements to conventional risk factors will improve the risk assessment in the setting of chronic kidney disease (CKD). The aim of the present study was to examine the correlation of NGAL with early stage renal impairment in CKD and to evaluate its prognostic value in these subjects. METHODS: This is a prospective observational cohort study of 54 patients with early stage (stage 1-2) CKD...

BACKGROUND: Normal kidney function or, more specifically, normal glomerular filtration rate (GFR) in men and women and its decline with age is still much debated today. The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation has gender (and race) multiplication factors, accounts for a decline that starts at very young age and assumes that the mean GFR is as high as 120-130 ml/min/1.73 m2 from a young age. The full age spectrum (FAS) estimated mean GFR is about 107 ml/min/1...

PURPOSE: To improve the resolution of elasticity maps by adapting motion and distortion correction methods for phase-based magnetic resonance imaging (MRI) contrasts such as magnetic resonance elastography (MRE), a technique for measuring mechanical tissue properties in vivo. MATERIALS AND METHODS: MRE data of the brain were acquired with echo-planar imaging (EPI) at 3T (n = 14) and 7T (n = 18). Motion and distortion correction parameters were estimated using the magnitude images...

Since the global Expanded Program on Immunization (EPI) was launched in 1974, vaccination against six diseases (tuberculosis, polio, diphtheria, tetanus, pertussis, and measles) has prevented millions of deaths and disabilities (1). Significant advances have been made in the development and introduction of vaccines, and licensed vaccines are now available to prevent 25 diseases (2,3). Historically, new vaccines only became available in low-income and middle-income countries decades after being introduced in high-income countries...

With the advent of ultra-high field MRI scanners in clinical research, susceptibility based MRI has recently gained increasing interest because of its potential to assess subtle tissue changes underlying neurological pathologies/disorders. Conventional, but rather slow, three-dimensional (3D) spoiled gradient-echo (GRE) sequences are typically employed to assess the susceptibility of tissue. 3D echo-planar imaging (EPI) represents a fast alternative but generally comes with echo-time restrictions, geometrical distortions and signal dropouts that can become severe at ultra-high fields...

Zoanthus kuroshio is a colorful zoanthid with a fluorescent pink oral disc and brown tentacles, which dominates certain parts of the Taiwanese and Japanese coasts. This sea anemone is a rich source of biologically active alkaloids. In the current investigation, two novel halogenated zoanthamines [5α-iodozoanthenamine (1) and 11β-chloro-11-deoxykuroshine A (2)], along with four new zoanthamines [18-epi-kuroshine A (3), 7α-hydroxykuroshine E (4), 5α-methoxykuroshine E (5), and 18-epi-kuroshine E (6)], and six known compounds were isolated from Z...

BACKGROUND: Our previous studies demonstrated that 2012 Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations were inaccurate enough for estimating glomerular filtration rate in elderly Chinese. Thus, this study was constructed to modify these equations. METHODS: A total of 839 subjects (aged ≥60 years) from four hospitals in China between October 2009 and December 2014 were included. A random sample of 674 (80.3 %) subjects was used as a training sample set, and the remaining 165 (19...

BACKGROUND: Neural tube defects (NTDs) are severe congenital malformations that arise from failure of neurulation during early embryonic development. The molecular basis underlying most human NTDs still remains largely unknown. Based on the hypothesis that folic acid prevents NTDs by stimulating methylation reactions, DNA methylation changes could play a role in NTDs. We performed a methylome analysis for patients with myelomeningocele (MMC). Using a candidate CpG analysis for HOX genes, a significant association between HOXB7 hypomethylation and MMC was found...

BACKGROUND: To introduce a modified surgical technique, the "parafoveal multiple curvelinear internal limiting membrane (ILM) peeling", to preserve epi-foveal ILM in myopic foveoschisis surgery. METHODS: Consecutive patients with myopic foveoschisis were enrolled in the present prospective interventional case series. The surgeries were performed using transconjunctival 23-gauge system. The macular area was divided into quadrants. ILM was peeled off in a curvilinear manner centered around the site that was away from the central fovea in each quadrant...

BACKGROUND: Researchers have developed several equations to predict glomerular filtration rate (GFR) in patients with chronic kidney diseases (CKD). However, there are scarcely any studies performed to discern the best equation to estimate GFR in patients with pure obstructive nephropathy. In present study, we assessed the suitability of six prediction equations and compared their performance in eGFR evaluation for Chinese patients with obstructive nephropathy. METHODS: A total of 245 adult patients with obstructive nephropathy were enrolled...
