UTARI researchers developing soft robotic glove for post-stroke hand rehabilitation
(University of Texas at Arlington) Initial rehabilitation therapy for many stroke victims may focus on regaining the ability to walk. But when hands also are affected, therapy focused only on the legs can leave hand muscles contracted, a condition that can be difficult to overcome.

Evaluating cardiac physiology through echocardiography in bottlenose dolphins: using stroke volume and cardiac output to estimate systolic left ventricular function during rest and following exercise RESEARCH ARTICLE
Stefan Miedler, Andreas Fahlman, Monica Valls Torres, Teresa Alvaro Alvarez, and Daniel Garcia-Parraga Heart-rate (fH) changes during diving and exercise are well documented for marine mammals, but changes in stroke volume (SV) and cardiac output (CO) are much less known. We hypothesized that both SV and CO are also modified following intense exercise. Using transthoracic ultrasound Doppler at the level of the aortic valve, we compared blood flow velocities in the left ventricle and cardiac frequencies during rest and at 1, 3 and 4 min after a bout of exercise in 13 adult bottlenose dolphins (Tursiops truncatus, six m...

Where Have All the Rodents Gone? The Effects of Attrition in Experimental Research on Cancer and Stroke
by Constance Holman, Sophie K. Piper, Ulrike Grittner, Andreas Antonios Diamantaras, Jonathan Kimmelman, Bob Siegerink, Ulrich Dirnagl Given small sample sizes, loss of animals in preclinical experiments can dramatically alter results. However, effects of attrition on distortion of results are unknown. We used a simulation study to analyze the effects of random and biased attrition. As expected, random loss of samples decreased statistical power, but biased removal, including that of outliers, dramatically increased probability of false positive results. Next, we performed a meta-analysis of animal reporting and attrition...

Nerve growth factor-carbon nanotube complex exerts prolonged protective effects in an in vitro model of ischemic stroke
Publication date: Available online 2 December 2016 Source:Life Sciences Author(s): Parichehr Hassanzadeh, Elham Arbabi, Fatemeh Atyabi, Rassoul Dinarvand Aims The therapeutic potential of nerve growth factor (NGF) against the neurological disorders may be negatively affected by its short half-life. Based on the superior properties of carbon nanotubes (CNTs) for controlled drug delivery, we aimed to prepare CNT-NGF complex and evaluate its effect in an in vitro model of ischemic stroke. Materials and methods Multi-walled CNTs (MWCNTs)-NGF complex was prepared using amino-functionalized COOH-MWCNTs and characterized by Four...

Molecular therapy set to protect at-risk patients against heart attack and stroke
(Charit é - Universit ä tsmedizin Berlin) Even a single dose of a specific ribonucleic acid molecule, known as a small interfering RNA (siRNA), offers patients at high risk of cardiovascular disease long-lasting protection against high LDL cholesterol -- one of the main risk factors for heart attack and stroke. This is the result of a clinical study that researchers from Charit é and Imperial College London have published as leading authors in the current edition of New England Journal of Medicine.

Ban on trans fats in diet may reduce heart attacks and stroke
(Yale University) People living in areas that restrict trans fats in foods had fewer hospitalizations for heart attack and stroke compared to residents in areas without restrictions, according to a study led by a Yale researcher. This finding suggests the benefit of limiting trans fats could have widespread impact as trans fat restrictions are set to expand nationwide.

Comparison of the Pharmacological Effects of Dimeric Dipeptide Nerve Growth Factor Mimetic GK-2 and Mexidol on the Model of Ischemic Stroke in Rats
We compared the effects of GK-2 (dimeric dipeptide mimetic of nerve growth factor) and Mexidol (standard preparation for the therapy of stroke) on rat model of transient occlusion of the middle cerebral artery. GK-2 and Mexidol were administered intraperitoneally in the most active doses (1 and 100 mg/kg, respectively) 6 h after surgery and then once a day for 6 days. The preparations reduced the volume of cerebral infarction (by 60 and 30%, respectively). At the same time, GK-2 had a pronounced and statistically more reliable effect in a dose that is lower by two orders of magnitude. In addition, GK-2 significantly reduce...

Phragmoplast expansion: the four-stroke engine that powers plant cytokinesis.
Abstract The phragmoplast is a plant-specific secretory module that partitions daughter cells during cytokinesis by constructing a cell plate from membranes and oligosaccharides. The cell plate is typically a long structure, which requires the phragmoplast to expand to complete cytokinesis. The phragmoplast expands by coordinating microtubule dynamics with membrane trafficking. Each step in phragmoplast expansion involves the establishment of anti-parallel microtubule overlaps that are enriched with the protein MAP65, which recruits cytokinetic vesicles through interaction with the tethering factor, TRAPPII. Cell ...

Ammar, Sameera RashidAbstractImmunocompromised status is associated with invasive fungal infections including mucormycosis. These infections are challenging to treat and associated with high overall mortality.Here we report a fatal case of invasive mucormycosis in a cirrhotic, diabetic patient. Despite the swift diagnosis and management; the fungal invasion of the right internal carotid artery lead to massive ischemic stroke.Timely diagnosis and management is crucial f...

Cell death mechanisms in stroke and novel molecular and cellular treatment options
(Bentham Science Publishers) As a result of ischemia or hemorrhage, blood supply to neurons is disrupted which subsequently promotes a cascade of pathophysiological responses resulting in cell loss. This review will explore the most updated cellular death mechanisms leading to neuronal loss in stroke.

Comparative Analysis of the Effects of Intravenous Administration of Placental Mesenchymal Stromal Cells and Neural Progenitor Cells Derived from Induced Pluripotent Cells on the Course of Acute Ischemic Stroke in Rats
We compared the effects of placental mesenchymal stromal cells and neural progenitor cells derived from induced human pluripotent cells after their intravenous administration to rats in 24 h after transitory occlusion of the middle cerebral artery. The therapeutic effects were evaluated by the dynamics of animal survival, body weight, neurological deficit, and the volume of infarction focus in 7, 14, 30, and 60 days after surgery. Intravenous injection of neural progenitor cells produced a therapeutic effect on the course of experimental ischemic stroke by increasing animal survival in the most acute period and acceleratin...
