We previously reported a patient who had developed 2 glioblastomas at the age of 54 and 64 years, respectively. The first glioblastoma in the right frontal lobe was treated with surgery and radiotherapy. Ten years later, the patient developed a second, left frontal glioblastoma. Discordant patterns of TP53 and PTEN mutations suggested that the second tumor was not a recurrence but an independently developed glioblastoma. To determine the molecular mechanism underlying this enigmatic case with 10-year survival, we performed whole-exome sequencing...

BACKGROUND AND PURPOSE: Headache disorders are considered one of the ten most disabling conditions, for both males and females, according to the World Health Organization. Chronic type tension headache (CTTH) has a prevalence of 2-3% within the general population. The purpose of this research was to investigate the effect of stimulating noninvasively the trigeminal nerve in the supraorbital area (SOES) for treatment of CTTH. METHODS: In an 8-week period of intervention, 45 patients were divided equally into three groups...

Evaluating performance validity is essential in neuropsychological and forensic assessments. Nonetheless, most psychological assessment tests are unable to detect performance validity and other methods must be used for this purpose. A new Performance Validity Test (DETECTS - Memory Performance Validity Test) was developed with several characteristics that enhance test utility. Moreover, precise response time measurement was added to DETECTS. Two groups of participants (normative and simulator group) completed DETECTS and three memory tests from the Wechsler Memory Scale III...

BACKGROUND AND AIMS: The activity of CYP2A6, the major nicotine-inactivating enzyme, is measurable in smokers using the nicotine metabolite ratio (NMR; 3'hydroxycotinine/cotinine). Due to its role in nicotine clearance, the NMR is associated with smoking behaviours and response to pharmacotherapies. The NMR is highly heritable (~80%), and on average lower in African Americans (AA) versus Whites. We previously identified several reduce and loss-of-function CYP2A6 variants common in individuals of African descent...

There currently is renewed interest in blood clotting Factor XII as a potential target for thrombosis inhibition. Historically untargeted, there is little drug information with which to start drug candidate searches. Typical high-throughput screening can identify potential drug candidates, but is inefficient. Virtual high-throughput screening can be used to raise efficiency by focusing experimental efforts on compounds predicted to be active and is applied here to identify new Factor XIIa inhibitors. We combine principal component analysis, genetic algorithm and support vector machine to create the models used in the virtual high-throughput screening...

The prokaryotic ATP-dependent ClpP protease, localized in the relict plastid of malaria parasite, represents a potential drug target. In the present study, we utilized in silico structure-based screening and medicinal chemistry approaches to identify a novel pyrimidine series of compounds inhibiting P. falciparum ClpP protease activity and evaluated their antiparasitic activities. Structure-activity relationship indicated that morpholine moiety at C2, an aromatic substitution at N3 and a 4-oxo moiety on the pyrimidine are important for potent inhibition of ClpP enzyme along with antiparasiticidal activity...

Biomass as a fuel for cooking is a common practice in rural India, and about 700 million people use traditional stoves to meet their energy demand. However, the thermal and the combustion efficiencies of these stoves are very low, leading to an inefficient use of biomass, and also, resulting in significant indoor air pollution. Research development has however led to the development of some improved stoves viz., natural draft and forced draft for both domestic as well as large scale cooking applications and government is trying to promote them...

Three-dimensional tumor spheroid models have been increasingly used to investigate and characterize cancer drug compounds. Previously, the Celigo image cytometer has demonstrated its utility in a high-throughput screening manner for evaluating potential drug candidates in a 3D multicellular tumor spheroid (MCTS) primary screen. In addition, we have developed real-time kinetic caspase 3/7 apoptosis and propidium iodide viability 3D MCTS assays, both of which can be used in a secondary screen to better characterize the hit compounds...

BACKGROUND: When symptoms of otitis media appear, parents and patients often access the Internet for health information. We study the content and quality of health information in parent-patient-focused websites for otitis media. METHODS: We searched the 3 search engines (Google, Yahoo, and Bing) using "otitis media" and "middle ear infection" then reviewed the top 30 hits for each search. We included sites that were focused on providing patient-patient information about otitis media...

The increasing accessibility of data to researchers makes it possible to conduct massive amounts of statistical testing. Rather than follow specific scientific hypotheses with statistical analysis, researchers can now test many possible relationships and let statistics generate hypotheses for them. The field of genetic epidemiology is an illustrative case, where testing of candidate genetic variants for association with an outcome has been replaced by agnostic screening of the entire genome. Poor replication rates of candidate gene studies have improved dramatically with the increase in genomic coverage, due to factors such as adoption of better statistical practices and availability of larger sample sizes...

Cyclophilin D (CypD) is a mitochondria-specific cyclophilin that is known to play a pivotal role in the formation of the mitochondrial permeability transition pore (mPTP).The formation and opening of the mPTP disrupt mitochondrial homeostasis, cause mitochondrial dysfunction and eventually lead to cell death. Several recent studies have found that CypD promotes the formation of the mPTP upon binding to β amyloid (Aβ) peptides inside brain mitochondria, suggesting that neuronal CypD has a potential to be a promising therapeutic target for Alzheimer's disease (AD)...

Thrombotic complications in pregnancy represent a major cause of morbidity and mortality. Pregnancy is a primary hypercoagulable state due to enhanced production of clotting factors, a decrease in protein S activity, and inhibition of fibrinolysis. These physiologic changes will yield a collective rate of venous thromboembolism (VTE) of about 1-2 in 1000 pregnancies for the general obstetric population, which represents a five- to tenfold increased risk in pregnancy compared to age-matched non-pregnant peers...

In the light of the promising bioactivity of the tetraarsenic marine metabolite arsenicin A, the dimethyl analogue 2 and four isomeric methylene homologues (including the natural product itself) were obtained using a one-pot microwave-assisted synthesis, starting from arsenic (III) oxide. Due to the poor diagnostic value of the NMR technique in the structural elucidation of these molecules, they were fully characterized by mass spectrometry and infrared (IR)-spectroscopy, comparing density functional theory (DFT) simulated and experimental spectra...

Exposure to polybrominated diphenyl ethers (PBDEs) during fetal development may be associated with deficits in attention and impulse control. However, studies examining postnatal PBDE exposures and inattention and impulsivity have been inconsistent. Using data from 214 children in the Health Outcomes and Measures of the Environment (HOME) Study, a prospective pregnancy and birth cohort with enrollment from 2003 to 2006 in the Greater Cincinnati Area, we investigated the relationship of both prenatal and postnatal PBDE exposures with attention and impulse control...

Influenza A virus (IAV) genomes are composed of eight single-stranded RNA segments that are coated by viral nucleoprotein (NP) molecules. Classically, the interaction between NP and viral RNA (vRNA) is depicted as a uniform pattern of 'beads on a string'. Using high-throughput sequencing of RNA isolated by crosslinking immunoprecipitation (HITS-CLIP), we identified the vRNA binding profiles of NP for two H1N1 IAV strains in virions. Contrary to the prevailing model for vRNA packaging, NP does not bind vRNA uniformly in the A/WSN/1933 and A/California/07/2009 strains, but instead each vRNA segment exhibits a unique binding profile, containing sites that are enriched or poor in NP association...
