https://www.readbyqxmd.com/read/28538994/predictive-feature-remapping-before-saccadic-eye-movements
#1
Dongjun He, Ce Mo, Fang Fang
Saccadic eye movements cause rapid and dramatic displacements of the retinal image of the visual world, yet our conscious perception of the world remains stable and continuous. A popular explanation for this remarkable ability of our visual system to compensate for the displacements is the predictive feature remapping theory. The theory proposes that, before saccades, the representation of a visual stimulus can be predictively transferred from neurons that initially encode the stimulus to neurons whose receptive fields will encompass the stimulus location after the saccade...

This article aims to estimate the prevalence and analyze the factors associated with cross-nursing. A cross-sectional study was conducted in 2013 with interviews with a representative sample of mothers of infants less than one-year-old (n' = 695) attended in nine primary health units in Rio de Janeiro, Brazil. Sociodemographic characteristics were studied; pregnancy, childbirth and primary care assistance; maternal habits and baby features. Adjusted prevalence ratios (PR) were obtained by Poisson Regression, retaining variables associated with the outcome in the final model (p ≤ 0...

Patients' knowledge about oral anticoagulant therapy may favor the achievement of therapeutic results and the prevention of adverse pharmacotherapy-related events. Brazil lacks validated instruments for assessing the patient's knowledge about treatment with warfarin. This study aimed to perform the cross-cultural adaptation of the Oral Anticoagulation Knowledge (OAK) Test instrument from English into Portuguese. This is a methodological study developed in an anticoagulation clinic of a public university hospital...

This study aimed to identify factors associated with dissatisfaction with dental services among adults. It analyzed 830 adult participants of an epidemiological survey of oral health. The dependent variable was dissatisfaction with the dental service, and the independent ones were selected according to the theoretical model set forth by Andersen and Davidson (1997). Estimates were corrected by the sample design effect, and Binary Logistic Regression was carried out. It was found that about 11% of adults were dissatisfied with the dental service...

Work stressors influence work ability - WA - and increasing age is associated with functional aging. We sought to establish whether work stressors differentially influence WA in young and aging nursing professionals. A cohort (2009-2011) composed of 304 workers at a hospital in Sao Paulo responded questionnaires Effort-Reward Imbalance (ERI), Job Stress Scale (JSS), Work-Related Activities That May Contribute To Job-Related Pain and/or Injury (WRAPI) and Work Ability Index (WAI). Changes in perceived exposure to stressors in each age group (< 45 and ≥ 45 years old) were compared to delta-WAI (difference between initial and final WAI score) by means of the Mann-Whitney test...

Lips are structures that play an essential role in aesthetics and in different functions such as nutrition and speech. The complex anatomy of the lips - with three different layers composed of skin, mucosa, and muscles - makes surgical management of this area a therapeutic challenge. The use of flaps for the reconstruction of large defects with low risk of necrosis is possible given the abundant blood supply of the lips. We report a case of surgical reconstruction of the lower lip after the excision of a severe squamous cell carcinoma using a skin-mucosa Abbe-Estlander flap with a satisfactory final outcome...

Colorectal cancer (CRC) is the fourth leading cause of cancer-induced mortality. Histone deacetylase 2 (HDAC2) is involved in prognosis and therapy of CRC. This study aimed to explore novel therapeutic targets for CRC. The alteration of HDAC2 expression in CRC tissues was estimated by qRT-PCR. After lentivirus transfection, HDAC2 knockdown was confirmed by western blot analysis. The effect of HDAC2 knockdown on cell proliferation was then assessed by 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay...

Objective: To evaluate the effects that passive cycling exercise, in combination with conventional physical therapy, have on peripheral muscle strength, duration of mechanical ventilation, and length of hospital stay in critically ill patients admitted to the ICU of a tertiary care university hospital. Methods: This was a randomized clinical trial involving 38 patients (≥ 18 years of age) on mechanical ventilation who were randomly divided into two groups: control (n = 16), receiving conventional physical therapy; and intervention (n = 22), receiving conventional physical therapy and engaging in passive cycling exercise five days per week...

Tomasz P Wypych, Benjamin J Marsland
From an evolutionary standpoint, allergy has only recently emerged as a significant health problem. Various hypotheses were proposed to explain this, but they all indicated the importance of rapid lifestyle changes, which occurred in industrialized countries in the last few decades. In this review, we discuss evidence from epidemiological and experimental studies that indicate changes in dietary habits may have played an important role in this phenomenon. Based on the example of dietary fiber, we discuss molecular mechanisms behind this and point towards the importance of diet-induced changes in the microbiota...

Over the past decades, peroxisomes have emerged as key regulators in overall cellular lipid and reactive oxygen species metabolism. In mammals, these organelles have also been recognized as important hubs in redox-, lipid-, inflammatory-, and innate immune-signaling networks. To exert these activities, peroxisomes must interact both functionally and physically with other cell organelles. This review provides a comprehensive look of what is currently known about the interconnectivity between peroxisomes and mitochondria within mammalian cells...

BACKGROUND: Advances in three-dimensional imaging and three-dimensional printing technology have expanded the frontier of presurgical design for microtia reconstruction from two-dimensional curved lines to three-dimensional perspectives. This study presents an algorithm for combining three-dimensional surface imaging, computer-assisted design, and three-dimensional printing to create patient-specific auricular frameworks in unilateral microtia reconstruction. METHODS: Between January of 2015 and January of 2016, six patients with unilateral microtia were enrolled...

BACKGROUND: Decellularized cadaveric tendons are a potential source for reconstruction. Reseeding to enhance healing is ideal; however, cells placed on the tendon surface result in inadequate delivery. The authors used an injection technique to evaluate intratendinous cell delivery. METHODS: Decellularized tendons were reseeded with adipose-derived stem cells in culture, and injected with fetal bovine serum or hydrogel. PKH26-stained cells in cross-section were quantified...

The evaluation of the electrically induced bulbocavernosus reflex (BCR) using electromyography (EMG) is a useful tool for evaluating the integrity of sacral spinal segments 2 to 4, and that of their afferent and efferent connections in the urogenital region. In the current retrospective study, the value of this technique in predicting the outcome of bladder dysfunction was investigated in patients with cauda equina syndrome (CES). Electrically induced BCR (E-BCR) was evaluated in 40 patients with bladder dysfunction due to CES at the subacute stage (7-90 days)...
