BACKGROUND: Lung adenocarcinoma (LUAD) is the most common histologic subtype of lung cancer and has a high risk of distant metastasis at every disease stage. We aimed to characterize the genomic landscape of LUAD and identify mutation signatures associated with tumor progression. METHODS AND FINDINGS: We performed an integrative genomic analysis, incorporating whole exome sequencing (WES), determination of DNA copy number and DNA methylation, and transcriptome sequencing for 101 LUAD samples from the Environment And Genetics in Lung cancer Etiology (EAGLE) study...

The primary goals of compulsory, inpatient, psychiatric treatment are to decrease dangerous behaviors and help improve functioning so that a safe discharge to a less restrictive environment can be obtained. This study examined the aggression rates, levels of functioning, and treatment adherence for persons treated for schizophrenia (N = 506) compared with persons treated for borderline personality disorder (BPD) (N = 98) in an inpatient psychiatric facility. Over half of persons engaged in at least one incident of aggressive behavior during hospitalization...

Background: There are limited treatments available for autism spectrum disorder (ASD). Studies have reported significant associations between the receptor genes of oxytocin (OT) and vasopressin (AVP) and ASD diagnosis, as well as ASD-related phenotypes. Researchers have also found the manipulation of these systems affects social and repetitive behaviors, core characteristics of ASD. Consequently, research involving the oxytocin/vasopressin pathways as intervention targets has increased. Therefore, further examination into the relationship between these neuropeptides and ASD was undertaken...

INTRODUCTION: Wipple disease (WD) is a rare chronic disease caused by the bacillus Tropheryma whipplei. Constitutive, rheumatologic, gastrointestinal, cardiac, cerebral, lymphatic, cutaneous, and ophthalmological signs are possible systemic symptoms. However, thrombotic manifestations are rarely described as "stroke-like syndrome" or arterial thrombosis. Diagnosis is based on clinical manifestations and pathological examination. Laboratory findings may include anemia, leukocytosis, and thrombocytosis...

Preeclampsia is a hypertensive disorder of pregnancy, responsible for over 60 000 maternal deaths annually. Endothelial dysfunction is a central aspect to its pathophysiology, and currently, no medical therapeutic is available for its treatment. In this study, we aim to investigate the effect of epidermal growth factor (EGF) on endothelial dysfunction using primary human tissues. We performed a number of in vitro assays that mimic the vascular endothelial dysfunction that occurs in preeclampsia. Epidermal growth factor reduced the expression of vascular cell adhesion molecule-1, a marker of endothelial dysfunction, after insult with tumor necrosis factor α (TNF-α) or serum from women with preeclampsia...

BACKGROUND: Adolescents are physically, cognitively, socially, and emotionally different than adults in ways that may partially explain why alcohol misuse typically develops during this period. Ample animal-science evidence and nascent ecological evidence points toward developmentally limited differences in sensitivity to alcohol's stimulatory and sedative effects. Field-based research methods were used to test for such age-related differences in a sample of adolescents through young adults...

Ipilimumab (IPI) is a monoclonal antibody that targets the inhibitory CTLA4 receptor of T cells, enhancing T-cell-driven antitumor responses. IPI therapy in metastatic melanoma results in significant improvement in disease-free and overall survival, although after initial responses disease progression generally ensues. Identification of specific responses in tissue where melanoma tumor cells are subjected to IPI-driven immune attack may reveal mechanisms of treatment efficacy or resistance, permitting refinement of targeted therapeutic approaches...

BACKGROUND: Muay Thai is a combat sport of Thailand that uses stand-up striking along with various clinching techniques. Currently, little is known about the injuries and risk factors for injuries among Muay Thai fighters. Gaining more insight into the nature and frequency of injury in this sport provides part of the overall sports injury picture, within the larger burden of injury as a public health issue. Generating this information is a critical first step toward the broader goal of improving the health and safety of Muay Thai fighters engaged in competition...

Feldspar minerals are the most common rock formers in Earth's crust. As such they play an important role in subjects ranging from geology to climate science. An atomistic understanding of the feldspar structure and its interaction with water is therefore desirable, not least because feldspar has been shown to dominate ice nucleation by mineral dusts in Earth's atmosphere. The complexity of the ice/feldspar interface arising from the numerous chemical motifs expressed on the surface makes it a challenging system...

Among the minorities underserved by today׳s healthcare system, the lesbian, gay and bisexual (LGB) population may be the least studied, and the least understood by healthcare providers. High-quality evidence is often lacking regarding optimal preventive care measures, both in medical areas that (to date) fail to identify differences in need between LGB and heterosexual patients, and in those more prevalent in or more specific (or both) to sexual minorities. Issues of substance abuse, sexual health and sexually transmitted diseases, obesity and other eating disorders, cardiovascular prevention, cancer prevention and screening, depression and other psychological disorders, social isolation and personal and intimate partner violence are all as or more important to address in LGB patients as they are in the general American population...

PURPOSE: There have been an increasing number of studies involving ultra-high-field 7T of intracranial pathology, however, comprehensive clinical studies of neuropathology at 7T still remain limited. 7T has the advantage of a higher signal-to-noise ratio and a higher contrast-to-noise ratio, compared to current low field clinical MR scanners. We hypothesized 7T applied clinically, may improve detection and characterization of intracranial pathology. MATERIALS AND METHODS: We performed an IRB-approved 7T prospective study of patients with neurological disease who previously had lower field 3T and 1...

The paper continues the series of publications from the International Nuclear Workers Study cohort (INWORKS) that comprises 308,297 workers from France, the United Kingdom and the United States, providing 8.2 million person-years of observation from a combined follow-up period (at earliest 1944 to at latest 2005). These workers' external radiation exposures were primarily to photons, resulting in an estimated average career absorbed dose to the colon of 17.4 milligray. The association between cumulative ionizing radiation dose and cancer mortality was evaluated in general relative risk models that describe modification of the excess relative risk (ERR) per gray (Gy) by time since exposure and age at exposure...

The plant PHosphate Transporter 1 (PHT1) family of membrane proteins belongs to the major facilitator super family and plays a major role in the acquisition of inorganic phosphate (Pi) from the soil and its transport within the plant. These transporters have been well characterized for expression patterns, localization, and in some cases affinity. Furthermore, the crystal structure of a high-affinity eukaryotic phosphate transporter from the fungus Piriformospora indica (PiPT) has revealed important information on the residues involved in Pi transport...

OBJECTIVE: Squalor affects 1 in 1000 older people and is regarded as a secondary condition to other primary disorders such as dementia, intellectual impairment and alcohol abuse. Squalor frequently is associated with hoarding behaviour. We compared the neuropsychological profile of people living in squalor associated with hoarding to those presenting with squalor only. METHODS: This study is a retrospective case series of hospital inpatient and community healthcare services of 69 people living in squalor (49 from aged care, 16 from aged psychiatry, 3 from acute medical and 1 from a memory clinic)...
