In this study, we evaluated the psychometric properties of the items to measure the work-family conflict and the time use for personal care and leisure, included in the baseline questionnaire of the Longitudinal Study of Adult Health (ELSA-Brazil). We evaluated temporal stability (7-14 days) using kappa statistic and the validity of the construct by the correlation of Kendall's tau with other variables. Test-retest stability was discreet to moderate and the correlations were compatible with the underlying theory...

AIM: As no upper limit of the daily dose of gonadotropins (DD GN) used for controlled ovarian hyperstimulation (COH) in patients undergoing assisted reproductive technology (ART) has been established, we aimed to evaluate the efficacy of using different DD GN in terms of live-birth achievement. METHODS: Data of patients treated at a single university medical center during the same period was analyzed retrospectively. Four groups were analyzed according to the DD GN administered: group I ("high dose"):  >225- ≤ 375 IU; Group II ("Very high dose"): 376-450 IU; group III ("extremely high dose"): 451-600 IU...

UNLABELLED: We present a technique that uses a near-point string to demonstrate the anticipated near point of multifocal and accommodating intraocular lenses (IOLs). Beads are placed on the string at distances corresponding to the near points for diffractive and accommodating IOLs. The string is held up to the patient's eye to demonstrate where each of the IOLs is likely to provide the best near vision. FINANCIAL DISCLOSURE: None of the authors has a financial or proprietary interest in any material or method mentioned...

Anti-N-Methyl-D-Aspartate receptor encephalitis is a recently described entity (Dalmau et al. 2007, 2008) that may present with a variety of complex movements in addition to other features (Kleinig et al. 2008). The purpose of our presentation of such a patient is twofold: (1) to characterize these complex oculo-oro-linguo-masticatory and limb movements with "smooch sign" as myorhythmia, based on a combined clinical and electrophysiological analysis (Masucci et al. 1984); and (2) to document possibly characteristic EEG evolution in the course of observation in our institution for three weeks from diffuse slowing to evolving rhythmic delta activity, which may represent a pattern of electrographic seizure activity...

Underutilized plant species has started changing the conception of plants by expanding the use well beyond from foods and fibers to rich source of medicinally important secondary metabolites. Bioactive compounds from natural sources are gaining importance as potential drug candidates towards many inflammatory conditions like Rheumatoid Arthritis (RA). The focus of the present study has been centred to reveal the anti-inflammatory potential of an underutilized fruits of B. sapida. Further efforts towards its medicinal significance may provide relieve from symptoms of RA by reducing the side effects that are observed in available medications...

New technologies are revealing genetic variants of unknown significance (VUS), raising questions about the indications that call for preimplanation genetic diagnosis (PGD). Two couples requesting PGD for VUS are presented. The first couple requested PGD for Lynch syndrome. Whole exome sequencing identified in a healthy male with a family history of Lynch-associated tumours, a MLH1 missense variant. The variant had not been reported as pathogenic, but was predicted as damaging by algorithms. The second couple had a child diagnosed with pervasive developmental disorder and intellectual disability, carrying a microduplication on chr:Xp...

When and where is an idea dispersed? Social media, like Twitter, has been increasingly used for exchanging information, opinions and emotions about events that are happening across the world. Here we propose a novel visualization design, "Whisper", for tracing the process of information diffusion in social media in real time. Our design highlights three major characteristics of diffusion processes in social media: the temporal trend, social-spatial extent, and community response of a topic of interest. Such social, spatiotemporal processes are conveyed based on a sunflower metaphor whose seeds are often dispersed far away...

Can data from mobile phones be used to observe economic shocks and their consequences at multiple scales? Here we present novel methods to detect mass layoffs, identify individuals affected by them and predict changes in aggregate unemployment rates using call detail records (CDRs) from mobile phones. Using the closure of a large manufacturing plant as a case study, we first describe a structural break model to correctly detect the date of a mass layoff and estimate its size. We then use a Bayesian classification model to identify affected individuals by observing changes in calling behaviour following the plant's closure...

ETHNOPHARMACOLOGICAL RELEVANCE: Bai-Hu-Tang (BHT) has been traditionally used to clear heat and engender fluids. AIM OF THE STUDY: To reveal the alteration of differentially expressed genes (DEGs) between lipopolysaccharide (LPS) febrile syndrome in rabbits and treatment with BHT which is a classical anti-febrile formula in traditional Chinese medicine. MATERIALS AND METHODS: Febrile model was induced by LPS injection (i.v.) in rabbits, and BHT was gavaged to another group of febrile rabbits...

Do leaders persuade? Social scientists have long studied the relationship between elite behavior and mass opinion. However, there is surprisingly little evidence regarding direct persuasion by leaders. Here we show that political leaders can persuade their constituents directly on three dimensions: substantive attitudes regarding policy issues, attributions regarding the leaders' qualities, and subsequent voting behavior. We ran two randomized controlled field experiments testing the causal effects of directly interacting with a sitting politician...

We examined whether treatment with minimum-dose stimulation (MS) protocol enhances clinical pregnancy rates compared to high-dose stimulation (HS) protocol. A retrospective cohort study was performed comparing IVF and pregnancy outcomes between MS and HS gonadotropin-antagonist protocol for patients with poor ovarian reserve (POR). Inclusion criteria included patients with an anti-Müllerian hormone (AMH) ≤8 pmol/L and/or antral follicle count (AFC) ≤5 on days 2-3 of the cycle. Patients from 2008 exclusively had a HS protocol treatment, while patients in 2010 had treatment with a MS protocol exclusively...

At Leghorn hens in the second half of embryogenesis and in 4-day-old chicks are studied reaction volume flow velocity (VF) in the superficial layers of the cerebral hemispheres and in skeletal muscle (Lazer Doppler FIowmetry) after the local influence of norepinephrine and sodium nitroprusside. It is shown that the response to these substances begins to manifest itself in the hemisphere in the last quarter of embryogenesis and authentically expressed by the end of it and in the chickens. It is noted that the response to these substances skeletal muscle VF (according to the new and previously published data on gastrocnemius and pectoral muscle) is also clearly manifested by the end of embryogenesis...

Search is a ubiquitous property of life. Although diverse domains have worked on search problems largely in isolation, recent trends across disciplines indicate that the formal properties of these problems share similar structures and, often, similar solutions. Moreover, internal search (e.g., memory search) shows similar characteristics to external search (e.g., spatial foraging), including shared neural mechanisms consistent with a common evolutionary origin across species. Search problems and their solutions also scale from individuals to societies, underlying and constraining problem solving, memory, information search, and scientific and cultural innovation...
