Construction of an individualized sensory space of tastes in water using skin blood flow responses
Perception of tastes and odors in water is a major interest for water producers and distributors because off-flavors in tap water are associated with health risk by consumers. However, the taste of water is difficult to describe due to the medium itself which is supposed to have no taste. Classical sensory methodologies are difficult to adapt and only get part of the whole perception. This ...

Brain region distribution and patterns of bioaccumulative perfluoroalkyl carboxylates and sulfonates in East Greenland polar bears (Ursus maritimus)
The present study investigated the comparative accumulation of perfluoroalkyl acids (PFAAs) in eight brain regions of polar bears (Ursus maritimus, n = 19) collected in 2006 from Scoresby Sound, East Greenland. The PFAAs studied were perfluoroalkyl carboxylates (PFCAs, C6–C15 chain lengths) and sulfonates (C4, C6, C8, and C10 chain lengths) as well as selected precursors including ...

Added value of advanced perfusion parameters in Moyamoya patients - Case Study
Introduction Moyamoya disease (MMD) is a cerebrovascular disease characterised by progressive steno-occlusion of the terminal part of the internal carotid arteries, causing a decline in cerebral perfusion pressure (CPP) distal to the steno-occlusion lesion. This will trigger a haemodynamic and metabolic response to preserve the cerebral metabolic rate of oxygen (CMRO2). Cerebral auto-regulation ...

SAVVE - Ongoing Pivotal - Case Study
Chronic Venous Insufficiency (CVI) occurs when the valves inside the veins of your leg do not function properly, causing blood to flow backwards and pool in the lower leg, leading to elevated venous pressure inside the leg veins. The purpose of the SAVVE study is to determine whether the VenoValve® is a safe and effective treatment for patients with severe, deep venous ...

Amplifi Vein Dilation System: A novel device under development designed to prepare veins for AVF creation
The Amplifi Vein Dilation System (Artio Medical) is is an innovative device designed to dilate arm veins in preparation for AVF surgery using rapid, non-pulsatile venous blood flow. Surendra Shenoy, M.D. (a vascular surgeon with specialist interest in vascular access and transplantation at Washington University School of Medicine, St Louis, Missouri, USA) describes the system as one of the most ...

What’s the difference between a heart attack, cardiac arrest and heart failure?
While heart attack, cardiac arrest and heart failure can sometimes be related, they’re actually three very different types of cardiac emergencies. Cardiac arrest, heart attack and heart failure — three terms that are familiar to most people, but often get confused with one another. While there can be some overlap between them in terms of cause and effect, they are actually three ...

Suture Knotting Techniques
Sutures are sterile surgical strands or threads used to sew damaged body tissues together after an injury and repair lacerations. Once the sutures are satisfactorily placed, they must be secured with knots, which should be tightened sufficiently to approximate the wound edges without constricting the tissues or impeding blood flow. That said, a completed knot should be firm so that it ...

How Hyaluronic Acid Promotes Pancreatic Cancer Cell Growth Revealed
Hyaluronic acid is known to be present in pancreatic tumors. However, in a new study, researchers from the University of Michigan Roger Cancer Center and the University of Pennsylvania found that hyaluronic acid also acts as a food for cancer cells. The results provide new insights into how pancreatic cancer cells grow and point to new possibilities for the treatment of this cancer. The relevant ...

Strengthen your pelvic floor
Many factors affect the strength of your pelvic floor muscles without that you even notice it. Whether it is a question of posture or just because you often carry heavy loads, it is important to adopt good habits and strengthen your pelvic floor to protect it during effort or exertion. There is also a multitude of other factors that damage your pelvic floor. Pregnancy, age and aging tissues, the ...

An Early Study on the Mechanisms that Allow Tissue-Engineered Vascular Grafts to Resist Intimal Hyperplasia
Abstract : Intimal hyperplasia is one of the prominent failure mechanisms for arteriovenous fistulas and arteriovenous access grafts. Human tissue-engineered vascular grafts (TEVGs) were implanted as arteriovenous grafts in a novel baboon model. Ultrasound was used to monitor flow rates and vascular diameters throughout the study. Intimal hyperplasia in the outflow vein of TEVGs was assessed at ...

Academic research conclusion: Is exercising inside hyperbaric chamber the next big thing?
The beneficial effects of hyperoxia supplementation on oxygen transport system capacity, lactic acid metabolism capacity, power output performance, and endurance exercise tolerance have been described in multiple previous studies (Sperlich et al., 2017; Cardinale and Ekblom, 2018). With regard to exercise performance, Knight et al. (1993) used a combination of femoral arterial and venous ...

7 Things You Should Know About Artificial Hearts
Artificial hearts may sound like science fiction, but they’ve actually been in clinical use to help end-stage heart failure patients for more than 35 years — here’s what you should know. As the number of patients suffering from heart disease has increased over the years, so too has the need for heart transplants. Unfortunately, the global supply of donor hearts remains limited, ...

Physiology and Pathology of Coronary Microcirculation
The heart is a unique organ in many respects since its activity is mandatory to sustain life. The heart’s circulatory system and coronary flow regulation are highly adapted to the vital role of the heart in sustaining life and to everyday physiological challenges. Understanding coronary physiology is key for treating patients with ischemic heart disease in general, and ...

Bioprinting Algae To Improve Tissue Oxygenation
Engineers often rely on Mother Nature to help solve difficult problems. After millions of years of evolution, living organisms such as plants, animals, and microbes have discovered how to survive in even the harshest of environments. Often times, organisms from different species are able to provide each other with the nutrients, resources, or protection that both need to prosper. We call ...
