The dimer of the amyloid-beta peptide Aβ of 42 residues is the smallest toxic species in Alzheimer's disease, but its equilibrium structures are unknown. Here we determined the equilibrium ensembles generated by the four atomistic OPLS-AA, CHARMM22*, AMBER99sb-ildn and AMBERsb14 force fields with the TIP3P water model. Based on 144 microsecond replica exchange molecular dynamics simulations (with 750 ns per replica), we find that the four force fields lead to random coil ensembles with calculated cross-collision sections, hydrodynamics properties and small-angle X-ray scattering profiles independent on the force field...

Multiple therapeutic agents have been developed to target the phosphatidylinositol 3-kinase (PI3K) signaling pathway, which is frequently dysregulated in cancer promoting tumor growth and survival. These include pan PI3K inhibitors, which target class Ia PI3K isoforms and have largely shown limited single agent activity with narrow therapeutic windows in clinical trials. Here, we characterize SN32976, a novel pan PI3K inhibitor, for its biochemical potency against PI3K isoforms and mTOR, kinase selectivity, cellular activity, pharmacokinetics, pharmacodynamics and antitumor efficacy relative to five clinically-evaluated pan PI3K inhibitors: buparlisib, dactolisib, pictilisib, omipalisib and ZSTK474...

BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic and potentially life threatening condition resulting from excessive ovarian stimulation. Reported incidence of moderate to severe OHSS ranges from 0.6% to 5% of in vitro fertilization (IVF) cycles. The factors contributing to OHSS have not been completely explained. The release of vasoactive substances secreted by the ovaries under human chorionic gonadotrophin (hCG) stimulation may play a key role in triggering this syndrome...

As the United States transitions from a volume-based health care system to one that rewards value, new frameworks are emerging to help patients, providers, and payers assess the value of medical services and biopharmaceutical products. These value assessment frameworks are intended to support various types of health care decision making. They have the potential to substantially affect patients, whether as tools for shared decision making with their doctors, as an input to care pathways used by providers, or through payer use of the frameworks to make coverage or reimbursement decisions...

REVIEW
Elliott M Antman
Some drugs used to treat noncardiovascular conditions may adversely impact the cardiovascular status of individuals both with and without known cardiovascular disease. When the US Food and Drug Administration judges the potential cardiovascular safety signal to be of sufficient concern, it may require the pharmaceutical manufacturer of the drug in question to conduct a postmarketing (phase 4) randomized controlled trial (RCT). Although historically many phase 4 RCTs focused on efficacy (using a superiority design), contemporary phase 4 RCTs often are focused on safety and use a noninferiority design...

Pasteurella multocida is a pathogen causing disease in a wide range of hosts including sheep and pigs. Isolates from ovine pneumonia were characterized by MLST (Multi-host and RIRDC databases) and virulence-associated gene (VAG) typing and compared with porcine isolates. Ovine and porcine isolates did not share any STs as determined by both schemes and exhibited different VAG profiles. With the Multi-host database, sixteen STs were identified among 43 sheep isolates with two STs (ST50 and ST19) comprising 53...

OBJECTIVE: To validate the application of an automated neuronal spike classification algorithm, Wave_clus (WC), on interictal epileptiform discharges (IED) obtained from human intracranial EEG (icEEG) data. METHOD: Five 10-min segments of icEEG recorded in 5 patients were used. WC and three expert EEG reviewers independently classified one hundred IED events into IED classes or non-IEDs. First, we determined whether WC-human agreement variability falls within inter-reviewer agreement variability by calculating the variation of information for each classifier pair and quantifying the overlap between all WC-reviewer and all reviewer-reviewer pairs...

Multifocal visual evoked potential (mf-VEP) represents a new approach to the classical full field (ff-)VEP with separate responses from up to 60 sectors of the visual field. A thorough literature survey of the use of mf-VEP in optic neuritis (ON) and multiple sclerosis (MS) is presented (38 published studies were retrieved). Mf-VEP provides direct topographical information of specific lesions and facilitates investigations on structural-functional correlations thus providing new methods for exploring the interplay between demyelination, atrophy and remyelination in MS...

Oleg V Krokhin
In a recent mini-review, Tarasova et al. (Analyst, 2016, 141, 4816) compared several peptide retention prediction models for reversed-phase HPLC developed for applied proteomics. The mechanism of peptide retention in RP-HPLC is very complex. Peptide separation selectivity is affected by multiple parameters of a separation system. Consequently, proper comparison of the models requires a detailed knowledge (to provide the best match) of separation conditions used to acquire both optimization and test datasets...

Michal Solomon, Eli Schwartz
Leishmaniasis is endemic in Israel and is increasing in its frequency. The pathogens that cause cutaneous leishmaniasis (CL) in Israel are Leishmania major (L. major) and Leishmania tropica (L. tropica). In recent years, there have been significant changes in the distribution of these species. L. major is endemic mainly in the Negev, Arava and the Beit She'an Valley. L. tropica is endemic in Tiberias, northern Sea of Galilee, Samaria and in the vicinity of Jerusalem such as at Kfar Adumim, Ma'ale Adumim and Anathoth (north-east of Jerusalem)...
