Nucleus accumbens-1 (NAC1), a nuclear factor belonging to the bric-a-brac-tramtrack-broad complex/pox virus and zinc finger gene family, is known to serve important roles in the proliferation and growth of tumor cells, and in chemotherapy resistance. However, the underlying molecular mechanisms through which NAC1 contributes to drug resistance remain unclear. In the present study, the role of NAC1 in drug resistance in ovarian cancer was investigated. NAC1 expression was markedly negatively associated with growth arrest and DNA-damage-inducible 45γ-interacting protein 1 (GADD45GIP1) expression in ovarian cancer...

BACKGROUND: A few bioactivities of constituents from Gynostemma laxum, which has been collected in Vietnam, have been reported until now. There is no report about the effects of constituents from G. laxum although the nuclear factor (erythroid-derived 2)-like 2 (Nrf2)-mediated heme oxygenase-1 (HO-1) antioxidant defense system is involved in neuroprotection in the brain. Therefore, we investigated whether quercetin (2), benzoic acid (10) and their analogues (1, 3-9 and 11) from G. laxum have the antioxidant and neuroprotective activities and also their underlying mechanism...

BACKGROUND: In rural Bangladesh, India and elsewhere, pour-flush pit latrines are the most common sanitation system. When a single pit latrine becomes full, users must empty it themselves and risk exposure to fresh feces, pay an emptying service to remove pit contents or build a new latrine. Double pit pour-flush latrines may serve as a long-term sanitation option including high water table areas because the pits do not need to be emptied immediately and the excreta decomposes into reusable soil...

Drinking and gambling frequently co-occur, and concurrent gambling and drinking may lead to greater negative consequences than either behavior alone. Building on prior research on the effects of alcohol, initial gambling outcomes, impulsivity, and gambling cognitions on gambling behaviors using a chance-based (nonstrategic) slot-machine task, the current study explored the impact of these factors on a skill-based (strategic) video poker task. We anticipated larger average bets and greater gambling persistence under alcohol relative to placebo, and expected alcohol effects to be moderated by initial gambling outcomes, impulsivity, and gambling cognitions...

BACKGROUND: Oxidative stress is one of the important factors involved in the pathogenesis of idiopathic pulmonary fibrosis (IPF). The equilibrium of Nuclear factor-erythroid-related factor 2 (Nrf2)/[BTB (broad-complex, tramtrack and bric-a-brac) and CNC (cap'n'collar protein) homology 1, Bach1] determines the expression level of antioxidant factors, further regulating the function of oxidation/antioxidation capacity. Pirfenidone (PFD) is one of two currently for IPF therapy approved drugs...

Drosophila leg morphogenesis occurs under the control of a relatively well-known genetic cascade, which mobilizes both cell signaling pathways and tissue-specific transcription factors. However, their cross-regulatory interactions, deployed to refine leg patterning, remain poorly characterized at the gene expression level. Within the genetically interacting landscape that governs limb development, the bric-à-brac2 (bab2) gene is required for distal leg segmentation. We have previously shown that the Distal-less (Dll) homeodomain and Rotund (Rn) zinc-finger activating transcription factors control limb-specific bab2 expression by binding directly a single critical leg/antennal enhancer (LAE) within the bric-à-brac locus...

BACKGROUND: Alcohol use and subsequent consequences are harmful for individual college students. Other students and the university can also be negatively impacted by the consequences of alcohol use. METHOD: A field-based study was used to assess the alcohol use environment at college parties. Researchers replicated a previous study by driving and walking a route to identify parties primarily on Thursday, Friday, and Saturday evenings between 9:00 PM and 1:00 AM across an academic year...

BACKGROUND: Although extra pulmonary tuberculosis (EPTB) has long been known as a major public health concern globally, the complex healthcare-seeking pathways of EPTB patients are not widely studied. This study aims to explore the pattern of healthcare-seeking pathways of rural and urban EPTB patients registered with the BRAC TB control programme. BRAC is a Bangladesh-based non-governmental organization dedicated to alleviating poverty through empowering the poor. METHOD: Data were collected through 60 in-depth interviews with rural and urban EPTB patients in Bangladesh...

INTRODUCTION AND AIMS: Subjective drunkenness measures may be useful screening tools for alcohol-related problems. However, if self-reported drunkenness is influenced by social and cultural understandings, the measure may not predict drinking patterns equally across different sociocultural groups. The current study aims to determine whether the two main sociocultural groups in Israel (Arabs and Jews) are equally likely to report drunkenness at comparable levels of breath alcohol content (BrAC)...

BACKGROUND AND AIM: Little evidence is available on whether respondents from divergent sociocultural populations report alcohol consumption in systematically similar ways. Therefore, this study examined whether the validity of self-reported alcohol use differed between Arab and Jewish Israeli pub patrons. METHODS: The analytical sample consisted of 227 Arab and 900 Jewish Israeli pub patrons who were approached as they left pubs and asked to record their Breath Alcohol Content (BrAC) value and complete a questionnaire that probed into their alcohol use...

OBJECTS: To date, multiple models have been developed to estimate blood or breath alcohol concentration (BAC/BrAC). Several factors have been identified that affect the discrepancy between BACs/BrACs and retrospective estimation (eBAC) with existing equations. To the best of our knowledge, a model to quantify the effects of factors on the discrepancy between BAC/BrAC and eBAC is still nonexistent. The goal of this work was to develop a model to provide a more accurate retrospective estimation of breath alcohol concentration (eBAC)...

BACKGROUND: Pancreatic adenocarcinoma (PA) is diagnosed in most cases at an advanced stage requiring chemotherapy. Folfirinox is the standard first-line treatment. After Folfirinox failure, gemcitabine alone is routinely used as second-line therapy without data supporting this attitude. AIM: Determine the response rate and outcome of patients with advanced PA treated with gemcitabine after Folfirinox failure. METHODS: We retrospectively analyzed all consecutive patients treated with gemcitabine after Folfirinox failure for a locally advanced or metastatic PA between 2009 and 2015...

Normal sexual differentiation in the genital organs is essential for the animal species that use sexual reproduction. Although it is known that doublesex (dsx) is required for the sexual development of the genitalia in various insect species, the direct target genes responsible for the sexual differentiation of the genitalia have not been identified. The lozenge (lz) gene is expressed in the female genital disc and is essential for developments of spermathecae and accessory glands in Drosophila melanogaster...

Cullin3 E3 ubiquitin ligase ubiquitinates a wide range of substrates through substrate-specific adaptors Bric-a-brac, Tramtrack, and Broad complex (BTB) domain proteins. These E3 ubiquitin ligase complexes are involved in diverse cellular functions. Our recent study demonstrated that decreased Cullin3 expression induces glioma initiation and correlates with poor prognosis of patients with malignant glioma. However, the substrate recognition mechanism associated with tumorigenesis is not completely understood...

BACKGROUND: Spaceflight alters human cardiovascular dynamics. The less negative slope of the fractal scaling of heart rate variability (HRV) of astronauts exposed long-term to microgravity reflects cardiovascular deconditioning. We here focus on specific frequency regions of HRV. METHODS: Ten healthy astronauts (8 men, 49.1 ± 4.2 years) provided five 24-hour electrocardiographic (ECG) records: before launch, 20.8 ± 2.9 (ISS01), 72.5 ± 3.9 (ISS02) and 152.8 ± 16...

Aims: Studies of social drinkers indicate that subjective response (SR) to alcohol and impulsivity are risk factors for the development of alcohol use disorder which may be related. It is unclear, however, whether there are significant relationships between SR and impulsivity among individuals with alcohol dependence. Using data from an intravenous (IV) alcohol challenge study, the present study is the first to explore the relationship between impulsivity and SR during alcohol administration among alcohol-dependent individuals...

Since May 2006, the BRAC Water, Sanitation and Hygiene (WASH) Programme in Bangladesh has enabled more than 30 million people to achieve hygienic sanitation, contributing to an increase in sanitation coverage from 33 to 83% in programme areas and rapid progress towards universal access. In rural areas, most families have single pit latrines that need to be emptied when full. Since 2007, BRAC has promoted the use of hygienic double-pit latrines. Use of double-pit latrines, where appropriate, is also recommended in the Bangladeshi Draft National Water Supply and Sanitation Strategy...
