PURPOSE: The evaluation and treatment for patients with prolonged periods of seriously impaired consciousness following traumatic brain injury (TBI), such as a vegetative or minimally conscious state, poses considerable challenges, particularly in the chronic phases of recovery. METHOD: This blinded crossover study explored the effects of familiar auditory sensory training (FAST) compared with a sham stimulation in a patient seven years post severe TBI. Baseline data were collected over 4 weeks to account for variability in status with neurobehavioral measures, including the Disorders of Consciousness scale (DOCS), Coma Near Coma scale (CNC), and Consciousness Screening Algorithm...

We investigated whether stimulating the cerebellum and primary motor cortex (M1) using transcranial direct current stimulation (tDCS) could affect postural control in young and older adults. tDCS was employed using a double-blind, sham-controlled design, in which young (aged 18-35) and older adults (aged 65+) were assessed over three sessions, one for each stimulatory condition-M1, cerebellar and sham. The effect of tDCS on postural control was assessed using a sway-referencing paradigm, which induced platform rotations in proportion to the participant's body sway, thus assessing sensory reweighting processes...

Virgin olive oil (VOO) is the only food product requiring official sensory analysis to be classified in commercial categories, in which the evaluation of the aroma plays a very important role. The selection of parents, with the aim of obtaining new cultivars with improved oil aroma, is of paramount importance in olive breeding programs. We have assessed the volatile fraction by headspace-solid-phase microextraction/gas chromatography-mass spectrometry-flame ionization detection (HS-SPME/GC-MS-FID) and the deduced aroma properties of VOO from a core set of olive cultivars (Core-36) which possesses most of the genetic diversity found in the World Olive Germplasm Collection (IFAPA Alameda del Obispo) located in Cordoba, Spain...

In many countries, infant cereals are one of the first foods introduced during the complementary feeding stage. These cereals are usually made with refined cereal flours, even though several health benefits have been linked to the intake of whole grain cereals. Prior evidence suggests that food preferences are developed at early stages of life, and may persist in later childhood and adulthood. Our aim was to test whether an infant cereal with 30% of whole grain was similarly accepted both by parents and infants in comparison to a similar cereal made from refined flour...

Estimating time to contact (TTC) involves multiple sensory systems, including vision and audition. Previous findings suggested that the ratio of an object's instantaneous optical size/sound intensity to its instantaneous rate of change in optical size/sound intensity (τ) drives TTC judgments. Other evidence has shown that heuristic-based cues are used, including final optical size or final sound pressure level. Most previous studies have used decontextualized and unfamiliar stimuli (e.g., geometric shapes on a blank background)...

Transient receptor potential vanilloid 1 (TRPV1) was identified as a receptor of capsaicin, which is a pungent ingredient in hot red peppers. Due to its relevance for nociception, a physiological and pharmacological study of TRPV1 has also been developed. Therefore, it is important to enrich scientific knowledge regarding the TRPV1 activating or inhibiting compounds. In this study, we fractionated soy sauce based on the human TRPV1 (hTRPV1) activity using column chromatography and purified 5-(9H-pyrido[3,4-b]indol-1-yl)-2-furanmethanol (perlolyrine) as an hTRPV1-activating compound...

Social anxiety disorder (SAD) is characterized by negatively biased perception of social cues and deficits in emotion regulation. While negatively biased perception is thought to maintain social anxiety, emotion regulation represents an ability necessary to overcome both biased perception and social anxiety. Here, we used laughter as a social threat in a functional magnetic resonance imaging (fMRI) study to identify cerebral mediators linking SAD with attention and interpretation biases and their modification through cognitive emotion regulation in the form of reappraisal...

The International Working Group (IWG) has classified Alzheimer's disease (AD) as two different types, the typical form and the atypical form, but clinicopathological studies of atypical AD are limited. Because atypical AD cases usually present with early-onset dementia, we investigated 12 patients with early-onset AD, including two patients with typical AD and 10 patients with atypical AD. Of these patients, six had the posterior variant, three had the frontal variant and one had the logopenic variant mixed with semantic dementia...

BACKGROUND Postoperative conversion disorder is rare and has been reported. The diagnosis is usually made after all major organic causes have been ruled out. CASE REPORT We describe a case of a 13-year-old female who presented in the post-anesthesia care unit with acute-onset inspiratory stridor and unresponsiveness to verbal or painful stimuli after receiving a general anesthetic for upper endoscopy. Later in the post-anesthesia care unit, she presented with acute-onset right hemiplegia and sensory loss. She was first evaluated for causes of her stridor and unresponsiveness...

PURPOSE: Neurectomy of the inguinal nerves may be considered for selected refractory cases of chronic postherniorrhaphy inguinal pain (CPIP). There is to date a paucity of easily applicable clinical tools to identify neuropathic pain and examine the neurosensory effects of remedial surgery. The present quantitative sensory testing (QST) pilot study evaluates a sensory mapping technique. METHODS: Longitudinal (preoperative, immediate postoperative, and late postoperative) dermatomal sensory mapping and a comprehensive QST protocol were conducted in CPIP patients with unilateral, predominantly neuropathic inguinodynia presenting for triple neurectomy (n = 13)...

Crossed cheiro-oral syndrome (CCOS) is characterized by crossed sensory disturbance confined to the unilateral perioral area and contralateral hand/finger(s). Although a few classical crossed sensory syndromes accurately predict brainstem or spinal involvement, the clinical significance of CCOS remains unclear. In this study, we analyzed the etiology, localization and outcome of CCOS patients. The results showed that ischemic stroke is the exclusive cause of CCOS. The location of responsible stroke is pertinent to the middle or upper level of the lateral medulla oblongata medial to the lateral sulcus...

Milk consumption in the United States has been in decline since the 1960s. Milk fat plays a critical role in sensory properties of fluid milk. The first objective of this study was to determine the change in percent milk fat needed to produce a detectable or just noticeable difference (JND) to consumers in skim, 1%, 2%, and whole milks. The second objective was to evaluate how milk fat affected consumer preferences for fluid milk. Threshold tests were conducted to determine the JND for each reference milk (skim, 1%, 2%, and whole milk), with a minimum of 60 consumers for each JND...

Spinal cord injury (SCI) results in permanent loss of motor and sensory function due to developmentally-related and injured-induced changes in the extrinsic microenvironment and intrinsic neuronal biochemistry that limit plasticity and axonal regeneration. Our long term goal is to develop cationic, amphiphilic copolymers (poly (lactide-co-glycolide)-g-polyethylenimine, PgP) for combinatorial delivery of therapeutic nucleic acids (TNAs) and drugs targeting these different barriers. In this study, we evaluated the ability of PgP to deliver siRNA targeting RhoA, a critical signaling pathway activated by multiple extracellular inhibitors of axonal regeneration...

Femoral nerve blocks (FNB) can provide effective pain relief but result in quadriceps weakness with increased risk of falls following total knee arthroplasty (TKA). Adductor canal block (ACB) is a relatively new alternative providing pure sensory blockade with minimal effect on quadriceps strength. The meta-analysis was designed to evaluate whether ACB exhibited better outcomes with respect to quadriceps strength, pain control, ambulation ability, and complications. PubMed, Embase, Web of Science, Wan Fang, China National Knowledge Internet (CNKI) and the Cochrane Database were searched for RCTs comparing ACB with FNB after TKAs...
