Banked blood doesn't deliver oxygen 
   
 
Abstract

Main Article from Howard Hughes Medical Institute

Blood flow in the microcirculation is regulated by physiological O2 gradients that are coupled to vasodilation and vasoconstriction, but the mechanism underlying this fundamental vascular response (which controls O2 delivery to tissues) has remained a major unanswered question in vascular physiology. The discovery of a previously unknown S-nitrosothiol (SNO) derivative of hemoglobin that has potent vasodilatory activity has changed the picture. Most significantly, the affinity of cysteine β93 for NO is high in the R (or oxy) structure and low in the T (or deoxy) structure. Thus, deoxygenatio...

Abstract
Leucine-rich repeat kinase-2 (LRRK2) mutations are a common cause of Parkinson's disease. In this paper, Byoung Dae Lee1, Joo-Ho Shin1, Jackalina VanKampen, Leonard Petrucelli, Andrew B West1, Han Seok Ko1, Yun-Il Lee1, Kathleen A Maguire-Zeiss, William J Bowers, Howard J Federoff, Valina L Dawson1 & Ted M Dawson have identified inhibitors of LRRK2 kinase that are protective in in vitro and in vivo models of LRRK2-induced neurodegeneration. The results establish that LRRK2-induced degeneration of neurons in vivo is kinase dependent and that LRRK2 kinase inhibition provides a potential new neuroprotective paradigm for the treatment of Parkinson's disease.

Title          
Echo Cardio Gram and Color Doppler 
   
 
Abstract

Echo Cardio Gram and Color Doppler.

An echocardiogram, often referred to in the medical community as a cardiac ECHO or simply an ECHO, is a sonogram of the heart. Also known as a cardiac ultrasound, it uses standard ultrasound techniques to image two-dimensional slices of the heart. The latest ultrasound systems now employ 3D real-time imaging.

In addition to creating two-dimensional pictures of the cardiovascular system, an echocardiogram can also produce accurate assessment of the velocity of blood and cardiac tissue at any arbitrary point using pulsed or continuous wave Doppler ultrasound. This allows assessment of cardiac valve areas and function, any abnormal communications between the left and right side of the heart, any leaking of blood through the valves (valvular regurgitation), and calculation of the

Title          
Sleep Apnea 
   
 
Abstract
Sleep apnea is a sleep disorder characterized by pauses in breathing during sleep. Each episode, called an apnea (Greek: ἄπνοια (Špnoia), from α- (a-), privative, πνέειν (pnťein), to breathe), lasts long enough so that one or more breaths are missed, and such episodes occur repeatedly throughout sleep. The standard definition of any apneic event includes a minimum 10 second interval between breaths, with either a neurological arousal (a 3-second or greater shift in EEG frequency, measured at C3, C4, O1, or O2), a blood oxygen desaturation of 3-4% or greater, or both arousal and desaturation. Sleep apnea is diagnosed with an overnight sleep test called a polysomnogram, or a "Sleep Study" which is often conducted by a pulmonologist.

Clinically significant levels of sleep apnea are defined as five or more episodes per hour of any type of apnea (from the polysomnogram). There are three distinct forms of sleep apnea: central, obstructive, and complex (i.e., a combination of central and obstructive) constituting 0.4%, 84% and 15% of cases respectively.[1] Breathing is interrupted by the lack of respiratory effort in central sleep apnea; in obstructive sleep...

Title          
Stem Cell Research Documentary 
   
 
Abstract
Stem Cell Research Initiative: why it's needed and what it does.Embryonic stem cells (ES cells) are stem cells derived from the inner cell mass of an early stage embryo known as a blastocyst. Human embryos reach the blastocyst stage 4-5 days post fertilization, at which time they consist of 50-150 cells. ES cells are pluripotent. This means they are able to differentiate into all derivatives of the three primary germ layers: ectoderm, endoderm, and mesoderm. These include each of the more than 220 cell types in the adult body. Pluripotency distinguishes ES cells from multipotent progenitor cells found in the adult; these only form a limited number of cell types. When given no stimuli for differentiation, (i.e. when grown in vitro), ES cells maintain pluripotency through multiple cell divisions. The presence of pluripotent adult stem cells remains a subject of scientific debate, however, research has demonstrated that pluripotent stem cells can be directly generated from adult fibroblast cultures.[1] Because of their plasticity and potentially unlimited capacity for self-renewal, ES cell therapies have been proposed for regenerative medicine and tissue replacement after injury or disease. However, to date, no approved medical...

Title          
New Diabetes Research 
   
 
Abstract
A discussion of Type 1 diabetes and stem cell treatment.Diabetes mellitus (IPA: /ˌdaɪəˈbiːtiːz/ or /ˌdaɪəˈbiːtəs/, /məˈlaɪtəs/ or /ˈmɛlətəs/), often simply diabetes (Greek: διαβήτης), is a syndrome characterized by disordered metabolism and inappropriately high blood sugar (hyperglycaemia) resulting from either low levels of the hormone insulin or from abnormal resistance to insulin's effects coupled with inadequate levels of insulin secretion to compensate.[2] The characteristic symptoms are excessive urine production (polyuria), excessive thirst and increased fluid intake (polydipsia), and blurred vision. These symptoms are likely absent if the blood sugar is only mildly elevated. The World Health Organization recognizes three main forms of diabetes mellitus: type 1, type 2, and gestational diabetes (occurring during pregnancy),[3] which have different causes and population distributions. While, ultimately, all forms are due to the beta cells of the pancreas being unable to produce sufficient insulin to prevent hyperglycemia, the causes are different.[4] Type 1 diabetes is usually due to ...
