Thermodynamic and thermophysical properties of Na2SiO3 in the Cmc21 structural state are computed ab-initio using the hybrid B3LYP density functional method. The static properties at the athermal limit are first evaluated through a symmetry-preserving relaxation procedure. The thermodynamic properties that depend on vibrational frequencies viz, heat capacities, thermal expansion, thermal derivative of the bulk modulus, thermal correction to internal energy, enthalpy, Gibbs free energy, are then computed in the framework of quasi-harmonic approximation...

BACKGROUND: Hamstring injuries are among the most common non-contact injuries in sports. The Nordic hamstring (NH) exercise has been shown to decrease risk by increasing eccentric hamstring strength. OBJECTIVE: The purpose of this systematic review and meta-analysis was to investigate the effectiveness of the injury prevention programs that included the NH exercise on reducing hamstring injury rates while factoring in athlete workload. METHODS: Two researchers independently searched for eligible studies using the following databases: the Cochrane Central Register of Controlled Trials via OvidSP, AMED (Allied and Complementary Medicine) via OvidSP, EMBASE, PubMed, MEDLINE, SPORTDiscus, Web of Science, CINAHL and AusSportMed, from inception to December 2015...

Nonnormality of univariate data has been extensively examined previously (Blanca et al., Methodology: European Journal of Research Methods for the Behavioral and Social Sciences, 9(2), 78-84, 2013; Miceeri, Psychological Bulletin, 105(1), 156, 1989). However, less is known of the potential nonnormality of multivariate data although multivariate analysis is commonly used in psychological and educational research. Using univariate and multivariate skewness and kurtosis as measures of nonnormality, this study examined 1,567 univariate distriubtions and 254 multivariate distributions collected from authors of articles published in Psychological Science and the American Education Research Journal...

Obstructive sleep apnea (OSA) is an independent risk factor for cardiovascular diseases. Aldosterone was reported to be increased in patients with OSA and correlated with OSA severity. Many studies investigated the effect of continuous positive airway pressure (CPAP) therapy on plasma aldosterone concentrations (PAC) in OSA patients. The results, however, were inconsistent. In the present study, we aimed to evaluate the effects of CPAP therapy on PAC by performing a meta-analysis. Literature search was carried out in electronic databases including PubMed/Medline, Cochrane Library, Embase and Web of Science...

Middle- and low-income countries bear 80 % of the global chronic disease burden. Population-level, multi-sectoral approaches to promoting healthful lifestyles that take into local physical, socioeconomic, and sociocultural characteristics of both the environment and the population are needed. The "Nuestra Voz (Our Voice)" is one such approach that involves neighborhood residents acting as "citizen scientists" to systematically gather information on the barriers and facilitators of physical activity in their neighborhoods and then use their data to collectively advocate for local environmental- and policy-level changes to support active living...

PURPOSE: This study aimed to investigate the relationship and reliability of cepstral peak prominence (CPP) measures from two acoustic software applications, Analysis of Dysphonia in Speech and Voice (ADSV) and Praat. METHODOLOGY: Flemish and English recordings of sustained vowels and connected speech samples were analyzed using ADSV and Praat. Correlational analyses and measures of the standard error of the estimate were applied to the vowel and connected speech data obtained from the two programs...

BACKGROUND: Identification of patients at highest risk of early stroke after transient ischaemic attack has been improved with imaging based scores. We aimed to compare the validity and prognostic utility of imaging-based stroke risk scores in patients after transient ischaemic attack. METHODS: We did a pooled analysis of published and unpublished individual-patient data from 16 cohort studies of transient ischaemic attack done in Asia, Europe, and the USA, with early brain and vascular imaging and follow up...

BACKGROUND: In an unprecedented rate data in the life sciences is generated and stored in many different databases. An ever increasing part of this data is human health data and therefore falls under data protected by legal regulations. As part of the BioMedBridges project, which created infrastructures that connect more than 10 ESFRI research infrastructures (RI), the legal and ethical prerequisites of data sharing were examined employing a novel and pragmatic approach. METHODS: We employed concepts from computer science to create legal requirement clusters that enable legal interoperability between databases for the areas of data protection, data security, Intellectual Property (IP) and security of biosample data...

Metastasis accounts for most of the deaths from breast cancer and the preference of invasive breast cancer metastasising to bone has been widely reported. However, the biological basis of breast cancer osteotropism is not fully understood. This paper provides, for the first time, an integrative, systematic review of evidence of molecular factors that have functional roles in the homing of metastatic breast cancer to the bone. Pubmed, Web of Science and EBSCOhost were searched using keywords and synonyms for molecular, metastasis, breast cancer and bone to identify articles published between January 2004 and August 2016...

BACKGROUND: Carpal tunnel syndrome (CTS) is a common peripheral nerve entrapment disease. Either surgical or conservative intervention for CTS patients is needed to choose. We conducted this systematic review and meta-analysis to compare the clinical efficacy, safety, and cost of surgical versus nonsurgical intervention. METHODS: The eligible studies were acquired from PubMed, Medline, Embase, Web of Science, Google, and Cochrane Library. The data were extracted by 2 of the coauthors independently and were analyzed by RevMan5...

Combination of docetaxel, cisplatin, and 5-fluorouracil (DCF) is an active but not well-tolerated regimen for advanced gastric cancer (GC) with standard 3-weekly doses. Several modified schedules (mDCFs) have been designed to reduce acute toxicities and improve feasibility as first-line therapy in patients with metastatic GC. The objective of this systematic review was to evaluate overall survival (OS), progression-free survival (PFS), overall response rate (ORR), and grade (G) greater than or equal to 3 adverse event of mDCF chemotherapy in this setting...

Post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD) are highly co-morbid in humans. Although we have some understanding of the structural and functional brain changes that define each of these disorders, and how those changes contribute to the behavioral symptoms that define them, little is known about the neurobiology of co-morbid PTSD and AUD, which may be due in part to a scarcity of adequate animal models for examining this research question. The goal of this review is to summarize the current state-of-the-science on co-morbid PTSD and AUD: we summarize epidemiological data documenting the prevalence of this co-morbidity, review what is known about the potential neurobiological basis for the frequent co-occurrence of PTSD and AUD, and discuss successes and failures of past and current treatment strategies...

BACKGROUND: Many treatments for the common cold exist and are sold over-the-counter. Nevertheless, evidence on the effectiveness and safety of nasal decongestants is limited. OBJECTIVES: To assess the efficacy, and short- and long-term safety, of nasal decongestants used in monotherapy to alleviate symptoms of the common cold in adults and children. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 6, June 2016), which contains the Cochrane Acute Respiratory Infections (ARI) Specialised Register, MEDLINE (1946 to July 2016), Embase (2010 to 15 July 2016), CINAHL (1981 to 15 July 2016), LILACS (1982 to July 2016), Web of Science (1955 to July 2016) and clinical trials registers...

BACKGROUND: Childhood caries (tooth decay) consists of a form of tooth decay that affects the milk teeth (also known as baby or primary teeth) of children. This may range from tooth decay in a single tooth to rampant caries affecting all the teeth in the mouth. Primary teeth in young children are vital to their development and every effort should be made to retain these teeth for as long as is possible. Dental fillings or restorations have been used as an intervention to repair these damaged teeth...
