Many evaluations have been carried out on the economic impact of pneumococcal vaccination in older adults (>64 years of age) in several countries, including Italy. However, these studies did not include the new data on the effectiveness of 13-valent conjugate pneumococcal vaccine (PCV13) in the elderly reported by the CAPiTA Study. The aim of the present study was to update our previous budget impact analysis of multi-cohort PCV13 vaccination in adults in Italy by including new scientific evidence. We also compared single-cohort vaccination strategies per year, in order to identify the cohort with the most favourable economic profile, in the event of the multi-cohort approach not being economically sustainable for the National Health System (NHS)...

The timing of the seasonal freeze-thaw cycle of arctic lakes affects ecological processes and land-atmosphere energy fluxes. We carried out detailed ice-phenology mapping of arctic lakes, based on daily surface-reflectance time series for 2000-2013 from MODIS at 250 m spatial resolution. We used over 13,300 lakes, area >1 km(2), in five study areas distributed evenly across the circumpolar Arctic - the first such phenological dataset. All areas showed significant trends towards an earlier break-up, stronger than previously reported...

BACKGROUND: Young adults often experiment with heavy use of alcohol, which poses severe health risks and increases the chance of developing addiction problems. In clinical patients, cognitive retraining of automatic appetitive processes, such as selective attention toward alcohol (known as "cognitive bias modification of attention," or CBM-A), has been shown to be a promising add-on to treatment, helping to prevent relapse. OBJECTIVE: To prevent escalation of regular use into problematic use in youth, motivation appears to play a pivotal role...

Pseudoneglect is the tendency for the general population to over-attend to the left. While pseudoneglect is classically demonstrated using line bisection, it also occurs for visual search. The current study explored the influence of eye movements and functional cerebral asymmetry on asymmetries for visual search. In Experiment 1, 24 participants carried out a conjunction search for a target within a rectangular array. A leftward advantage for detecting targets was observed when the eyes were free to move, but not when they were restricted by short exposure durations...

Oncogenic BRaf V600E mutation is involved in the development, invasion and metastasis of colon cancer. Selective inhibition of BRaf(V600E) mutant has been recognized as a therapeutic strategy for the cancer. Here, we carried out atomistic molecular dynamics (MD) simulations to characterize the structural basis, energetic property, and dynamics behavior of conformational change in BRaf activation loop upon the mutation. It is found that V600E mutation destabilizes inactive DFG-out conformation of activation loop and promotes its conversion to the active DFG-in conformation, thus conferring constitutive activity for BRaf kinase...

The clinical diagnosis of Lyme borreliosis can be supported by various test methodologies; test kits are available from many manufacturers. Literature searches were carried out to identify studies that reported characteristics of the test kits. Of 50 searched studies, 18 were included where the tests were commercially available and samples were proven to be positive using serology testing, evidence of an erythema migrans rash, and/or culture. Additional requirements were a test specificity of ≥85% and publication in the last 20 years...

Jian Ma, Yuan Yuan, Dongxing Yuan
The automated in-field determination of trace phosphate (and other nutrients) is highly valuable for studying nutrient dynamics and cycling in oligotrophic oceans. Here, we report an automated portable analyzer for week-long underway analysis of nanomolar dissolved reactive phosphorus (DRP) in seawater. The method is based on classic phosphomolybdenum blue (PMB) chemistry combined with on-line solid phase extraction (SPE) and flow analysis. Under optimized conditions, the formed PMB from sample is automatically concentrated on a hydrophilic lipophilic balanced (HLB) copolymer SPE...

REVIEW
Benjamin L Woolbright, Hartmut Jaeschke
Drug-induced acute liver failure carries a high morbidity and mortality rate. Acetaminophen overdose is the number one cause of acute liver failure and remains a major problem in Western medicine. Administration of N-acetyl cysteine is an effective antidote when given before the initial rise in toxicity; however, many patients present to the hospital after this stage occurs. As such, treatments which can alleviate late-stage acetaminophen-induced acute liver failure are imperative. While the initial mechanisms of toxicity are well described, a debate has occurred recently in the literature over whether or not there exists a second phase of injury, mediated by inflammatory processes...

The present work assessed the contributions of high root-mean-square (RMS) level (H-level, containing primarily vowels) and middle-RMS-level (M-level, with mostly consonants and vowel-consonant transitions) segments to the intelligibility of noise-masked and noise-suppressed sentences. In experiment 1, noise-masked (by speech-spectrum shaped noise and 6-talker babble) Mandarin sentences were edited to preserve only H- or M-level segments, while replacing the non-target segments with silence. In experiment 2, Mandarin sentences were subjected to four commonly-used single-channel noise-suppression algorithms before generating H-level-only and M-level-only noise-suppressed sentences...

J M V Grzybowski, E E N Macau, T Yoneyama
This work concerns analytical results on the role of coupling strength in the phenomenon of onset of complete frequency locking in power-grids modelled as a network of second-order Kuramoto oscillators. Those results allow estimation of the coupling strength for the onset of complete frequency locking and to assess the features of network and oscillators that favor synchronization. The analytical results are evaluated using an order parameter defined as the normalized sum of absolute values of phase deviations of the oscillators over time...

INTRODUCTION: The commercially available (68)Ge/(68)Ga generators are generally used in clinical context in conjunction with automated or semi-automated modules for the syntheses of (68)Ga radiopharmaceuticals. It is desirable to develop strategies for the formulation of (68)Ga-radiopharmaceuticals without use of such expensive modules in order to make (68)Ga-based clinical positron emission tomography (PET) more popular and affordable worldwide. METHODS: An organic matrix based (68)Ge/(68)Ga generator was used for preparation of clinically relevant doses of four different (68)Ga-based radiopharmaceuticals, namely (68)Ga-DOTA-NOC, (68)Ga-NODAGA-RGD2, (68)Ga-PSMA-11 and (68)Ga-BPAMD...
