Irregular sleep/wake patterns in student-athletes exposed to early morning training.

This study aimed to examine the sleep parameters and sleep/wake regularity of a cohort of student-athletes who start training between 06:30 and 07:00. Twenty-one male Rugby Union players, aged 21 ± 2 years and competing at a national level, were assessed using actigraphy over two weeks, and the Athlete Sleep Screening Questionnaire (ASSQ). Sleep/wake regularity was calculated using the Sleep Regularity Index (SRI).

HER2DX in HER2-positive inflammatory breast cancer: correlative insights and comparative analysis with noninflammatory breast cancers.

Background: The HER2DX assay predicts long-term prognosis and pathologic complete response (pCR) in patients with early-stage human epidermal growth factor receptor 2 (HER2)-positive breast cancer receiving neoadjuvant systemic therapy but has not been evaluated in inflammatory breast cancer (IBC).

Patients And Methods: HER2DX was analyzed in baseline biopsy tissues from 23 patients with stage III HER2-positive IBC on a phase II trial (NCT01796197) treated with neoadjuvant trastuzumab, pertuzumab, and paclitaxel (THP). To assess the assay's predictive accuracy for pCR in IBC, clinical-pathological features and outcomes from this IBC cohort were compared with 156 patients with stage III HER2-positive non-IBC from four different cohorts.

Differentiating the contributions of Na/K pump current and persistent Na current in simulated voltage-clamp experiments.

The persistent Na current (I) is thought to play important roles in many brain regions including the generation of inspiration in the ventral respiratory column (VRC) of mammals. The characterization of the slow inactivation of I requires long-lasting voltage steps (>1 s), which will increase intracellular Na and activate the Na/K-ATPase pump current (I). Thus, I may contribute to the previously measured slow inactivation of I and the generation of the inspiratory bursting rhythm.

Self-Collected Testing for Sexually Transmitted Infections: A National Text Message Survey of Adolescents and Young Adults.

Purpose: We aimed to analyze adolescent and young adults' (AYAs) perspectives on using sexually transmitted infection (STI) self-collection kits to help guide the provision and implementation of accessible and confidential reproductive health-care services for those who experience the burden of STIs and STI-related morbidity.

Methods: We utilized MyVoice, a nationwide text message survey of AYAs, to pose 6 open-ended questions on their perceptions and use of STI self-collection kits. Two independent reviewers used inductive content analysis to develop a codebook and analyze responses, and a third settled any coding discrepancies through discussion to reach consensus.

The saccade target is prioritized for visual stability in naturalistic scenes.

The present study investigated the mechanisms of visual stability using naturalistic scene images. In two experiments, we asked whether the visual system relies on spatial location of the saccade target, as previously found with simple dot stimuli, or relational positions of the objects in the scene during visual stability decisions. Using a modified version of the saccadic suppression of displacement task, we manipulated the information that is displaced in the scene as well as visual stability using intrasaccadic target blanking paradigm.
