There is an ongoing probing of the role of chemicals in the indoor environment. The majority of potential target substances are so-called very volatile, volatile and semi volatile organic compounds (VVOCs, VOCs and SVOCs). Depending on their physical properties and mass transfer conditions, they distribute in or between the gas phase, particle phase, settled house dust, surface films, clothing and other fabrics as well as the exposed skin and hair of the occupants themselves. Therefore, inhalation, ingestion and dermal uptake all must be considered as relevant pathways for the exposure assessment in human habitats...

The brain of arachnids contains a special neuropil area called the arcuate body (AB), whose function has been widely discussed. Its growth and proportion in the brain volume during postembryogenesis have been investigated only in several spider species. Our allometric study is aimed at determining to what extent the development of the AB in Eratigena atrica, a spider with unique biology and behaviour, is similar to the development of this body in other species. We put forward a hypothesis of allometric growth of this body in relation to the volume of the central nervous system (CNS) and its neuropil as well as in relation to the volume of the brain and its neuropil...

In off-line training of motor imagery-based brain-computer interfaces (BCIs), to enhance the generalization performance of the learned classifier, the local information contained in test data could be used to improve the performance of motor imagery as well. Further considering that the covariance matrices of electroencephalogram (EEG) signal lie on Riemannian manifold, in this paper, we construct a Riemannian graph to incorporate the information of training and test data into processing. The adjacency and weight in Riemannian graph are determined by the geodesic distance of Riemannian manifold...

INTRODUCTION: The functioning of the immune system during pregnancy is altered in both human immunodeficiency virus (HIV)-infected and uninfected women. Unfavorable socioeconomic conditions have been indicative of higher morbidity and mortality and worsening of the immune system. The aim of this study was to correlate social status with levels of interleukin (IL)-10 (non-inflammatory) and interferon-gamma (IFN-γ; inflammatory) cytokines. METHODS: A cross-sectional study was conducted with three groups of women: 33 pregnant HIV-infected (G1); 40 non-pregnant, HIV-infected (G2); and 35 pregnant, HIV-uninfected...

While much progress has occurred since the civil rights act of 1964, minorities have continued to suffer disparate and discriminatory access to economic opportunities, education, housing, health care and criminal justice. The latest challenge faced by the physicians and public health providers who serve the African American community is the detrimental, and seemingly insurmountable, causes and effects of violence in impoverished communities of color. According to statistics from the Centers for Disease Control (CDC), the number one killer of black males ages 10-35 is homicide, indicating a higher rate of violence than any other group...

BACKGROUND: Tuberculosis (TB) contact tracing is a key strategy for containing TB and provides addition to the passive case finding approach. However, this practice has not been implemented in Tanzania, where there is unacceptably high treatment gap of 62.1% between cases estimated and cases detected. Therefore calls for more aggressive case finding for TB to close this gap. We aimed to determine the magnitude and predictors of bacteriologically-confirmed pulmonary TB among household contacts of bacteriologically-confirmed pulmonary TB index cases in the city of Mwanza, Tanzania...

Much of the literature on ageing is presaged upon a model of advocacy that seeks to combat what is seen as the negative stereotyping of old age and old people. One consequence is that ageing studies has difficulty in confronting the darker side of ageing except in so far as age associated disability and distress can be attributed to extrinsic disadvantage, such as low income, poor housing and inadequate services. The pain and suffering associated with age itself tend to be neglected as subject experiences. This paper seeks to shed some light on these topics, considered under the general heading of 'suffering'...

RATIONALE, AIMS AND OBJECTIVES: This study explores the postconsultation follow-up behaviours of patients who used the Australian after-hours house-call (AHHC) medical services. These behaviours provide insights into the nature of the continuity of care (CoC) in the industry and are a measure quality in AHHC service delivery. Understanding the patterns of these CoCs and their predictors will enable stakeholders in the industry, both locally and globally, plan and implement higher quality services...

Polyhydroxybutyrate (PHB), a biodegradable polymer accumulated by bacteria is deposited intracellularly in the form of inclusion bodies often called granules. The granules are supramolecular complexes harbouring a varied number of proteins on their surface, which have specific but incompletely characterised functions. By comparison with other organisms that produce biodegradable polymers, only two phasins have been described to date for Rhodosprillum rubrum, raising the possibility that more await discovery...

BACKGROUND: ATAC-seq (Assays for Transposase-Accessible Chromatin using sequencing) is a recently developed technique for genome-wide analysis of chromatin accessibility. Compared to earlier methods for assaying chromatin accessibility, ATAC-seq is faster and easier to perform, does not require cross-linking, has higher signal to noise ratio, and can be performed on small cell numbers. However, to ensure a successful ATAC-seq experiment, step-by-step quality assurance processes, including both wet lab quality control and in silico quality assessment, are essential...

BACKGROUND: Homelessness is a persistent social issue with diverse impacts reaching far beyond individuals. Strategies and research concerning homelessness and health have largely focused on the risk factors and weaknesses of individuals. Such preoccupation has meant the potential strengths and resources within individuals, and so-called strength-based approaches have received less attention. Consequently, understanding how to effectively work with and engage this population in such interventions is limited...

We give operational meaning to wave-particle duality in terms of discrimination games. Duality arises as a constraint on the probability of winning these games. The games are played with the aid of an n-port interferometer, and involve 3 parties, Alice and Bob, who cooperate, and the House, who supervises the game. In one game called ways they attempt to determine the path of a particle in the interferometer. In another, called phases, they attempt to determine which set of known phases have been applied to the different paths...

The high incidence of meat of impaired quality poses a serious problem in the poultry industry. In recent years, the incidence of the pectoralis major muscle that appeared pale colored, remarkably hardened, and exudative, called "wooden breast" or "woody breast" has increased in slaughter houses. In the present study, 19-day-old Ross 308 broiler chickens affected (n = 10) and unaffected (n = 10) with remarkably hardened breast were selected from a commercial broiler farm, and reared to 55 days of age under a controlled environment...

Newly diagnosed breast abscesses are generally treated as a medical emergency that may necessitate immediate interventional treatment. At our institution, there is no in-house after-hours coverage for breast ultrasonography. We could find no peer-reviewed studies on the cost-effectiveness or clinical management impact of on-call ultrasound technologist coverage for imaging of breast abscesses. The purposes of this study were to determine the incidence of breast abscess in patients with clinical findings highly suggestive of abscess, identify clinical factors associated with breast abscess in such patients, and determine the impact of after-hours emergent or urgent breast ultrasonography on the clinical management of breast abscesses in both outpatients and inpatients...

Bioinformatic analysis is an integral and critical part of clinical next-generation sequencing. It is especially challenging for some pipelines to consistently identify insertions and deletions. We present the validation of an open source tumor amplicon pipeline (OTA-pipeline) for clinical next-generation sequencing targeting solid tumor-associated variants. Raw data generated from 557 TruSight Tumor 26 samples as well as in silico data were analyzed by the OTA-pipeline and legacy pipeline and compared. Discrepant results were confirmed by orthogonal methods...

Clinical Emotional Freedom Techniques (EFT) is an evidence-based treatment for depression and anxiety. The current study sought to elucidate the relationship between posttraumatic stress disorder (PTSD), depression, and anxiety in a nonclinical population. The sample (N = 81) comprised participants at five 2-day EFT workshops. All groups used an EFT protocol called Borrowing Benefits, in which the group facilitator works with a single client while other participants self-apply EFT. Participants were assessed on 9 specific conditions as well as on the breadth (Positive Symptom Total [PST]) and depth (General Symptom Index [GSI]) of psychological distress...

To ensure patient safety and protect the well-being of interns and residents, the Accreditation Council for Graduate Medical Education (ACGME) issued guidelines in 2003 limiting the working hours of physician trainees. Although many supported the goals of the ACGME, institutions struggled to restructure their programs and hire staff required by this unfunded mandate. Numerous studies have analyzed the effects of duty hours restrictions on patient outcomes and physician training over the past 15 years. Most agree that duty hours restrictions improved well-being of house officers, but these improvements came at the expense of continuity, and patient hand-offs led to medical errors...
