BACKGROUND: Anoxia leads to a robust generation of reactive oxygen species/nitrogen species which can result in mitochondrial dysfunction and associated cell death in the cerebral cortex of neonates. AIM: The present study investigated the pharmacological role of tempol in the treatment of rat neonatal cortical mitochondrial dysfunction induced insult progression (day-1 to day-7) and associated neurobehavioral alterations post-anoxia. METHODS: Rat pups of 30h age or postnatal day 2 (PND2) were randomly divided into 5 groups (n=5 per group): (1) Control; (2) Anoxia; (3) Anoxia+Tempol 75mg/kg; (4) Anoxia+Tempol 150mg/kg; and (5) Anoxia+Tempol 300mg/kg, and subjected to two episode of anoxia (10min each) at 24h of time interval in an enclosed chamber supplied with 100% N2...

Stroke is a major cause of death and disability, with most of its burden now affecting low- and middle-income countries (LMIC). People in rural areas of LMIC who have a stroke receive very little acute stroke care and local healthcare workers and family caregivers in these regions lack the necessary knowledge to assist them. Intriguingly, a recent rapid growth in cell-phone use and digital technology in rural areas has not yet been appropriately exploited for health care training and delivery purposes. What should be done in rural areas, at the community setting-level, where access to healthcare is limited remains a challenge...

The relationship between Guillain-Barré syndrome (GBS) and malignancy is uncertain. We retrospectively analyzed data of 118 consecutive patients admitted with GBS from Birmingham, U.K. (2001-2012). We calculated relative cancer risk using different definitions and determined characteristics of malignancy-associated GBS. Malignancy was globally commoner in our GBS cohort compared to the general population (odds ratio: 2.08; CI: 1.06-3.71; p=0.036). However, this was unconfirmed if paraneoplastic criteria were applied...

BACKGROUND: Disability-adjusted life-years lost after stroke in Low & Middle-Income Countries (LMICs) is almost seven times those lost in High-income countries. Although individuals living with chronic neurological and mental disorders are prone to stigma, there is a striking paucity of literature on stroke-related stigma particularly from LMICs. OBJECTIVE: To assess the prevalence, severity, determinants and psycho-social consequences of stigma among LMIC stroke survivors...

Post-hemorrhagic hydrocephalus (PHH), also referred to as progressive ventricular dilatation, is caused by disturbances in cerebrospinal fluid (CSF) flow or absorption following hemorrhage in the brain. As one of the most serious complications of neonatal/adult intraventricular hemorrhage (IVH), subarachnoid hemorrhage (SAH), and traumatic brain injury (TBI), PHH is associated with increased morbidity and disability of these events. Common sequelae of PHH include neurocognitive impairment, motor dysfunction, and growth impairment...

BACKGROUND: Dravet syndrome (DS) is a rare genetic epilepsy syndrome which is particularly pharmacoresistant. Vagus nerve stimulation (VNS) is commonly used in the treatment of DS as an adjunct to medical therapy. A meaningful assessment of post-surgical outcomes with VNS is difficult given the rarity of the condition. OBJECTIVE: In a novel approach, we used social media to contact patients with DS to gather data on post-surgical seizure reduction and overall satisfaction with VNS...

OBJECTIVE: We investigated neuronal correlates of faces versus non-faces processing in a cortically blind patient (TN) and a group of healthy age-matched controls in order to test electrophysiological correlates of the processing of pertinent stimuli in this patient. METHODS: An EEG paradigm was used, in which intact and scrambled faces were displayed on a screen. First, time-frequency transforms were conducted on the patients' data alone. These oscillations were then compared to the frontal activity of six control participants...

CONTEXT: Allopregnanolone is a metabolite from progesterone and a positive modulator of the GABAA receptor. This endogenous steroid may induce negative mood in sensitive women when present in serum levels comparable to the premenstrual phase. Its endogenous isomer, isoallopregnanolone, has been shown to antagonize allopregnanolone effects in experimental animal and human models. OBJECTIVE: The objective was to test whether inhibition of allopregnanolone by treatment with the GABAA modulating steroid antagonist (GAMSA) Sepranolone (UC1010) during the premenstrual phase could reduce symptoms of the premenstrual dysphoric disorder (PMDD)...

Group schema therapy (GST) has been proposed as a novel long-term treatment programme for borderline and cluster C personality disorders. We implemented a short-term GST programme (12-15 sessions, based on the manual by Farrell and Shaw (2012), including both cognitive / behavioural and experiential interventions for in-patients (n=9) with either borderline or cluster C personality disorders (and axis I co-morbidities) treated in a (sub)acute psychiatric in-patient setting. We evaluated pre- and post-treatment self-report of maladaptive and adaptive schema modes (using the SMI) and early maladaptive schemas (YSQ-3), as well as overall symptom severity (brief symptom check list, BSCL-53-S), patient satisfaction (ZUF-8) and group climate and coherence (GCQ-S)...

SCOPE: The uptake of dietary plant small RNAs (sRNAs) in consumers remains controversial, which is mainly due to low dietary content in combination with poor fractional absorption. MIR2911, among all the plant sRNAs including microRNAs, has been shown to be one of the most robustly absorbed sRNAs. Here we analyze the unusual abundance and unique genesis of MIR2911 during vegetable processing. METHODS AND RESULTS: Using qRT-PCR, the abundance of MIR2911 increased dramatically in macerated tissues while other microRNAs degraded...
