Functional Respiratory Imaging Can Predict the Course of Covid-19
Functional Respiratory Imaging (FRI) quantifies and visualizes the distribution of blood vessels in the lungs in great detail. This simple model, which combines the results of the imaging with the patient’s age, can accurately predict the risk of dying and the necessity for ventilation. Clinical research conducted has revealed that inflammation of the endothelium and microangiopathy occur ...

A Healthy Environment - In life sciences and pharmaceuticals, it’s the key to success
With 1,000 miles of airways, 60,000 miles of blood vessels, and 100 trillion cells1, the human body is often referred to as the world’s most complex machine. So it’s no surprise that industries such as pharmaceuticals and life sciences, devoted to keeping that machine in good working order, require a complex and highly exacting set of operating environments. Manufacturers in these ...

The Tumor Marker: Vascular Endothelial Growth Factor 165 (VEGF165)
Tumors and Blood Vessel Growth Tumor, as an abnormal mass of cells, has blood vessels of various sizes that can be seen everywhere on the surface and deep within it. Nutrients for life are continuously supplied to the depths of tumor cells through these blood vessels. As the tumor continues to grow, nearby blood vessels also undergo rapid and chaotic growth, with these newly formed capillaries ...

3D-printed blood vessels in monkeys marks medical breakthrough towards artificial organs
A Chinese firm has made a major medical breakthrough by succeeding in developing 3D-printed blood vessels that have been successfully implanted into monkeys, which is a major step towards making artificial human organs possible in future. Sichuan Revotek is a Chinese biotechnology firm that developed a 3D bioprinter back in 2015 which prints using stem cell-based bio ink, and it has now ...

Evaluation of Anti-Stroke Drugs
Stroke, also known as transient ischemic attack or cerebrovascular accident, is an acute brain disease. Usually, a sudden rupture of a blood vessel in the brain or a blockage of a blood vessel that prevents blood from flowing to the brain can cause damage to brain tissue, resulting in a stroke. Long-term strokes can lead to brain damage, disability and even death. The brain serves as a ...

Chinese company implants 3-D printed blood vessels into monkeys
Beijing, China (CNN)A major breakthrough in 3-D printed medicine could bring hope to nearly 1.8 billion patients with cardiovascular disease. Chinese scientists working for Sichuan Revotek have successfully 3-D printed blood vessels and implanted them in rhesus monkeys, the company said. It is a major step on the road to mass printing human organs for transplants. The company ...

Some results of studying laser micromachining at medical stents manufacturing
Cardio-vascular diseases are the number one killer in the world. As an alternative to common treatment methods the installation of specific-purpose stents into the damaged blood vessel could be used in order to minimise fatal outcomes. Existing technologies of stent manufacturing provide quite good results but are very expensive at the moment. The given paper deals with the design of stents for ...

What dermatologists need to know about Bartonella
Galaxy Diagnostics co-founder Dr. Ed Breitschwerdt on ReachMD with Dr. Michael Greenberg on what dermatologists should know about Bartonella species infections. Research over the past 30 years has shown that Bartonella species infect a wide array of cell types, including red blood cells and endothelial cells (in particular cells that line the blood vessels), in both people and ...

Arterial reconstruction with human bioengineered acellular blood vessels in patients with peripheral arterial disease
Abstract Objective: Vascular conduit is essential for arterial reconstruction for a number of conditions, including trauma and atherosclerotic occlusive disease. We have developed a tissue-engineered human acellular vessel (HAV) that can be manufactured, stored on site at hospitals, and be immediately available for arterial vascular reconstruction. Although the HAV is acellular when implanted, ...

Understanding and Treating Diabetic Neuropathy
What is diabetic neuropathy? The most common complication of diabetes is neuropathy, which is nerve damagecaused by high blood sugar. Most neuropathy affects the legs, hands and feet and usually presents as numbness, pain or tingling. Diabetic neuropathy can also seriously impact the heart, blood vessels, digestive system and the kidneys. Symptoms can range from mild discomfort to extreme pain. ...

Dissolved Hydrogen Application
Hydrogen molecule is the smallest molecule in nature. It is extremely penetrating and extremely volatile. It can freely enter and exit the body cells, remove aging and toxic free radicals. After drinking, it enters human body tissues and diffuses to act on all organ line particles and nucleus. Absorbed by the body. Realize the balance of the environment in the body and initiate the mechanism of ...

NovoSorb BTM: Application & Delamination
Most superficial wounds (ones involving the epidermis and sometimes the partial dermis) heal quickly, often without scarring, and typically covered with readily available wound dressings. However, when trauma occurs and large portions of the epidermis and dermis are destroyed, it may be necessary to put a structure in place to aid the body in generating new tissue. NovoSorb® BTM is a fully ...

Effect of endothelium mimicking self-assembled nanomatrices on cell adhesion and spreading of human endothelial cells and smooth muscle cells
Abstract The goal of this study is to develop unique native endothelium mimicking nanomatrices and evaluate their effects on adhesion and spreading of human umbilical vein endothelial cells (HUVECs) and aortic smooth muscle cells (AoSMCs). These nanomatrices were developed by self-assembly of peptide amphiphiles (PAs) through a solvent evaporation technique. Three PAs, one containing the ...

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 ...

Calcium Alginate Wound Dressings - Still Relevant Forty Years On!
SFM has been producing alginate products since the early 1980’s and still to this day alginates are an important product for our business. Alginate dressings are classed as ‘advanced wound care’, a label that up until now I have strongly disagreed with. How can a relatively simple dressing be thought of as ‘advanced’ in the current market? With newer ...

Microfluidic tools to investigate pathologies in the blood microcirculation
We show how microfluidics technology can be used to fabricate simple and innovative biomimetic tools to shed new light on physiopathological events occurring in the blood microcirculation. Examples of applications are given in the context of the acute respiratory distress syndrome (ARDS), an inflammatory disease of the lung triggered by a massive arrest of white blood cells in the lung ...

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 ...
