No data exist on the impact of cultivation practices on food safety risks associated with cucumber. Cucumbers are typically grown horizontally over a mulch cover, with fruit touching the ground, but this vining plant grows well in vertical systems. To assess whether production system affects bacterial dispersal onto plants, field trials were conducted over 2 years. Cucumber cultivar 'Marketmore 76' was grown horizontally on plastic, straw, or bare ground or vertically on trellises installed on bare ground in soil previously amended with raw dairy manure...

During goal-directed arm movements, the eyes, head, and arm are coordinated to look at and reach the target. We examined whether the expectancy of visual information about the target modifies Anticipatory Postural Adjustments (APAs). Ten standing subjects had to (1) move the eyes, head and arm, so as to reach, with both gaze and index-finger, a target of known position placed outside their visual field (Gaze-Reach); (2) look at the target while reaching it (Reach in Full Vision); (3) keep the gaze away until having touched it (Reach then Gaze) and (4) just Gaze without Reach the target...

PREMISE OF THE STUDY: The stigmas of several species are touch sensitive and respond to pressure by closing. Previous research suggests that stigma closure could prevent self pollination within a flower during a pollinator's visit or enhance male function by increasing pollen export. Both factors could be favored in outcrossers, and neither would be beneficial in selfers. METHODS: We investigated variation in stigma-closing and the duration of closure in annual and perennial populations of the variable species Mimulus guttatus and whether four closely related selfing species (M...

Congenital muscular dystrophies display a wide phenotypic and genetic heterogeneity. The combination of clinical, biochemical, and molecular genetic findings must be considered to obtain the precise diagnosis and provide appropriate genetic counselling. Here we report five individuals from four families presenting with variable clinical features including muscular dystrophy with a reduction in dystroglycan glycosylation, short stature, intellectual disability, and cataracts, overlapping both the dystroglycanopathies and Marinesco-Sjögren syndrome...

Ciliary disorders, which are also referred to as ciliopathies, are a group of hereditary disorders that result from dysfunctional cilia. The latter are cellular organelles that stick up from the apical plasma membrane. Cilia have important roles in signal transduction and facilitate communications between cells and their surroundings. Ciliary disruption can result in a wide variety of clinically and genetically heterogeneous disorders with overlapping phenotypes. Because cilia occur widespread in our bodies many organs and sensory systems can be affected when they are dysfunctional...

Research shows that preschoolers are likely to anthropomorphize not only animals, but also inanimate toy after being exposed to books that personify these objects. Can such an effect also arise through young children's use of touch-screen games? The present study is the first to examine whether playing a touch-screen personified train game affects young children's anthropomorphism of real trains. Seventy-nine 4- and 6-year-old children were randomly assigned to play either a touch-screen game or a board game of Thomas the Tank Engine for 10 min...

Historically, research on emotion perception has focused on facial expressions, and findings from this modality have come to dominate our thinking about other modalities. Here we examine emotion perception through a wider lens by comparing facial with vocal and tactile processing. We review stimulus characteristics and ensuing behavioral and brain responses and show that audition and touch do not simply duplicate visual mechanisms. Each modality provides a distinct input channel and engages partly nonoverlapping neuroanatomical systems with different processing specializations (e...

Brood parasitism frequently leads to a total loss of host fitness, which selects for the evolution of defensive traits in host species. Experimental studies have demonstrated that recognition and rejection of the parasite egg is the most common and efficient defence used by host species. Egg-recognition experiments have advanced our knowledge of the evolutionary and coevolutionary implications of egg recognition and rejection. However, our understanding of the proximate mechanisms underlying both processes remains poor...

<ce:para>This scoping review examines the effects of touch/massage on agitation and stress in aged hospitalized patients suffering from dementia. This intervention is multidimensional, at the edges of medical neurosciences, nursing sciences, and social sciences. This review is primarily supported by a biological model of social relations, describing the interconnection between cognition, affect, and endocrine aspects of attachment modes. It is also guided by nursing sciences conceptualizations which anchors touch/massage in the heart of nursing practice...

Low intensity, non-noxious, stimulation of cutaneous somatosensory nerves has been shown to trigger oxytocin release and is associated with increased social motivation, plus reduced physiological and behavioural reactivity to stressors. However, to date, little attention has been paid to the specific nature of the mechanosensory nerves which mediate these effects. In recent years, the neuroscientific study of human skin nerves (microneurography studies on single peripheral nerve fibres) has led to the identification and characterisation of a class of touch sensitive nerve fibres named C-tactile afferents...

Acupuncture is a therapeutic treatment that is characterised by the insertion of a needle at a particular location on the body. Acupuncture stimulation includes sensory-discriminative and affective-social touch dimensions. In this review, we discuss the role of touch during acupuncture stimulation with an emphasis on the therapeutic, sensory-discriminative and affective-social aspects. In the discriminative dimension, de qi, which is associated with needling, includes a combination of various sensations, such as heaviness, numbness, soreness and distension...

Perivascular adipose tissue (PVAT) releases multiple factors and adipokines with paracrine effects on both vascular structure and function. This influence is variable depending on regional differences in PVAT among blood vessels and with changes in adiposity. Considerable evidence demonstrates the association between coronary PVAT and the development and progression of coronary artery disease, associated with inflammation, oxidative stress, angiogenesis, vascular remodeling and blood clotting. However, PVAT also has a protective role on vascular grafts, especially the no-touch saphenous vein, in patients undergoing coronary artery bypass...

Humans are able to judge the speed of an object's motion by touch. Research has suggested that tactile judgment of speed is influenced by physical properties of the moving object, though the neural mechanisms underlying this process remain poorly understood. In the present study, functional magnetic resonance imaging was used to investigate brain networks that may be involved in tactile speed classification and how such networks may be affected by an object's texture. Participants were asked to classify the speed of 2-D raised dot patterns passing under their right middle finger...

AIM OF THE STUDY: Since there have been only few works reporting the diagnosis of kidneys using Acoustic Radiation Force Impulse technique and those works do not provide consistent results of shear wave velocity measurements in renal tissue, we have decided to use kidney phantoms with known properties to examine the reliability of the method itself in a controlled setup similar to kidneys examination. MATERIALS AND METHODS: Four gelatin-based phantoms imitating different clinical situations were manufactured - two with thick and two with thin renal cortex, each type at a depth similar to a normal-weight or overweight patient...

Spinal cord injury (SCI) is a devastating condition that affects patient on a personal as well as on a societal level. The objective of the study is to improve the prediction of long-term functional outcome following SCI based on the acute clinical findings. 76 patients with acute traumatic SCI were prospectively enrolled in a cohort study in a single level I trauma center. Spinal Cord Independence Measure (SCIM) at 1 year after the trauma was the primary outcome. Potential predictors of functional outcome were recorded during the acute hospitalization: age, sex, level and type of injury, comorbidities, American Spinal Injury Association (ASIA) Impairment Scale (AIS), ASIA Motor Score (AMS), ASIA Light Touch score (LT), ASIA Pin Prick score (PP), Injury Severity Score (ISS), Traumatic Brain Injury (TBI) and delay from trauma to surgery...

C-mechanoreceptors in humans comprise a population of unmyelinated afferents exhibiting a wide range of mechanical sensitivities. C-mechanoreceptors are putatively divided into those signaling gentle touch (C-tactile afferents, CTs) and nociception (C-mechanosensitive nociceptors, CMs), giving rise to positive and negative affect, respectively. We sought to distinguish, compare and contrast the properties of a population of human C-mechanoreceptors to see how fundamental the divisions between these putative subpopulations are...

INTRODUCTION: Various behaviors, such as physical activity and sleep, have been shown to have stress-reducing and beneficial effects on wellbeing. In contrast, the rewarding effects of eating and drinking have rarely been investigated, particularly using ecologically valid approaches, and little is known about mediating mechanisms on the biological level. METHODS: Seventy-seven healthy young adults completed items on eating and drinking as well as momentary wellbeing (measured by mood, energy, tension, stress and fatigue levels) on an iPod touch 5×/day for 4 consecutive days...

This paper presents a vibrotactile haptic feedback system for use under dynamic conditions, verifies its functionality, and shows how results may be affected by the amount of training that subjects receive. We hope that by using vibrotactile feedback to distinguish between different textures, upper-limb amputees may be able to partially regain the sense of touch. During a previous experiment [23], we noticed a correlation between how familiar the subjects were with haptic systems, and how well they were able to use the haptic system to accurately identify textures...
