BACKGROUND: Long COVID describes a condition with symptoms that linger for months to years following acute COVID-19. Many of these are like those experienced by patients myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). OBJECTIVE: We wanted determine if people post-exertional malaise (PEM), the hallmark symptom ME/CFS, and so, how it compared PEM ME/CFS. METHODS: A questionnaire asked about domains including triggers, experience, recovery, prevention was administered 80 seeking...

Understanding and predicting individual responses to common stressors is essential for optimising performance in high-stress environments. This article outlines a protocol study identify biomarkers that predict under heat, musculoskeletal, psychosocial sleep stress, future integration into wearable sensor system. In Phase I, healthy adults aged between 18 45 years (n=104) will be recruited an intervention trial involves exposure one of the four stressors: or deprivation. Biomarkers...

Peritoneal exudate cells (PEC), obtained after the rejection of EL4 leukemia by BALB/c mice, are much more effective in specific vitro destruction 51Cr-labeled than spleen, thymus, lymph node, or peripheral blood lymphocytes. The presence a large number effector at site graft is reflected potent cytolytic activity seen vitro. Effector temporarily lose reactivity when treated with trypsin but regain time. This recovery occurs normal as well immune serum. destructive PEC increased macrophages...

While dance may improve motor features in Parkinson's disease (PD), it is not yet clear if the benefits extend to non-motor features.To determine whether classes based on Dance for PD®, cognition, psychological symptoms and Quality of Life (QoL) PD.Participants were allocated a Group (DG; n = 17) or Control (CG: 16). Participants had early-stage PD (Hoehn & Yahr: DG 1.6±0.7, CG 1.5±0.8) with no cognitive impairment (Addenbrooke's score: 93.2±3.6, 92.6±4.3). The undertook one-hour class,...

Post-concussion syndrome (PCS) is a controversial constellation of cognitive, emotional, and physical symptoms that some patients experience following mild traumatic brain injury or concussion. PCS-like are commonly found in individuals with depression, pain, stress, as well healthy individuals. This study investigated the base rate PCS sample 96 participants examined relationship between these symptoms, demographics. were assessed using British-Columbia Post-Concussion Symptom Inventory....

Clinically, individuals diagnosed with Parkinson disease (PD) present several symptoms that impact on their functional independence and quality of life. While there is accumulating evidence supporting dance as an effective symptom management option, few studies have objectively assessed these benefits, particularly related to the Dance for Parkinson's Disease® (DfPD®) program.The aim this study was explore effects DfPD®-based classes disease-related symptoms, fine-manual dexterity mobility...

A pathway for cell-mediated tumor destruction in vitro by immune peritoneal exudate lymphoid cells has been proposed. The union of lymphocytes and precedes the formation an intermediate phase leading to lysis. initial interaction is only partially temperature dependent. cytolytic process per se highly dependent, being negligible at 25°C but proceeding rapidly 37°C. 51Cr release from demonstrable within 10 min 37°C can be reversibly arrested cooling. Once initiated, lysis largely independent...

Background and objectives Neuromuscular complications are almost universal in CKD by the time that a patient commences dialysis. Recent studies have indicated chronic hyperkalemia may contribute to development of neuropathy CKD.

Sleep disturbance after mild traumatic brain injury (mTBI) is commonly reported as debilitating and persistent. However, the nature of this poorly understood. This study sought to characterize sleep mTBI compared with a control group. A cross-sectional matched case design was used. Thirty-three persons recent (1-6 months ago) 33 age, sex, ethnicity controls completed established questionnaires quality, quantity, timing, sleep-related daytime impairment. The participants were an independent...

Background Some patients with acute COVID-19 are left persistent, debilitating fatigue, cognitive impairment (“brain fog”), orthostatic intolerance (OI) and other symptoms (“Long COVID”). Many of the like those post-infectious fatigue syndromes may meet criteria for myalgic encephalomyelitis/chronic syndrome (ME/CFS). Common diagnostic laboratory tests often unrevealing. Methods We evaluated whether a simple, standardized, office-based test OI, 10-min NASA Lean Test (NLT), would aggravate...

Postconcussion symptoms are relatively common in the acute recovery period following mild traumatic brain injury (MTBI).However, for a small subset of patients, self reported postconcussion continue long after injury.Many factors have been proposed to account presence persistent symptoms.The influence personality traits has as one explanation.The purpose this study was examine relation between postconcussion-like symptom reporting and sample 96 healthy participants.Participants completed...

Lymphocytes in peritoneal exudate from BALB/c mice immunized against ascites leukemia EL4 are uniquely efficient at destroying 51 chromium-labeled cells vitro. The lytic process depends upon the number of lymphocyte-tumor cell interactions. Effector lymphocytes not inactivated as a result lethal contact but can interact repeatedly with tumor cells.
