Researchers discover exploiting microbiome bacteria in patients with lung infections improves low oxygen levels

Posted by in categories: biotech/medical, health

Newspaper headlines from the U.S. to the U.K. and most places in between highlight the surge in sick patients suffering from respiratory viruses. The so-called “tripledemic” of lung infections including respiratory synclinal virus (RSV), influenza (flu) and COVID-19 (coronavirus) is likely to last throughout the winter season. This explosion of infections requires more treatment options to support overloaded hospitals and overworked medics as they restore people’s health.

It has been known for a long time that intubation of an infant with any , or even an adult with severe COVID-19 using either ventilation or extra-corporeal membrane oxygenation (ECMO), comes with risks and that could cause permanent damage not limited to the lungs. However, hypoxia, which means , is a that is a common complication of severe . If not treated, it can lead to severe disability and even death.

An Organism That Can Dine Exclusively on Viruses Has Been Found in a World First

Posted by in category: biotech/medical

A type of freshwater plankton has become the first organism seen thriving on a diet of viruses, according to a new study by researchers from the University of Nebraska-Lincoln in the US.

Viruses are often consumed incidentally by a range wide of organisms, and may even season the diets of certain marine protists. But to qualify as a true step in the food chain – described as virovory – viruses ought to contribute a significant amount of energy or nutrients to their consumer.

The microbe Halteria is a common genus of protist known to flit about as its hair-like cilia propel it through the water. Not only did laboratory samples of the ciliate consume chloroviruses added to its environment, the giant virus fueled Halteria’s growth and increased its population size.

IKnife Helps Find Endometrial Cancer

Posted by in category: biotech/medical

Point-of-care diagnoses occur when a doctor can quickly diagnose a patient during an examination without sending biological samples to a laboratory or consulting with other specialists. The stress and anxiety that can come with waiting for the results of medical testing, and the cost associated with in-depth laboratory testing, make point-of-care testing a gold standard. However, point-of-care diagnostics remain rare in oncology.

Research shows that women suspected of endometrial cancer experience stress and anxiety while waiting for a confirmed diagnosis. While the procedures and waiting time associated with endometrial cancer diagnoses vary, endometrial biopsies can take weeks to return results. Of added concern, since most endometrial cancers require surgical intervention, usually a hysterectomy, delays in diagnosis lead to delays in treatment. Indeed, these surgical delays can negatively impact survival. Thus, rapid endometrial cancer diagnostic strategies would significantly improve patient care.

Investigating the intestinal transport of mercury ions with a gut-on-a-chip device

Posted by in categories: biotech/medical, chemistry, engineering, life extension

The transport of mercury ions across intestinal epithelial cells can be studied for toxicology assessments by using animal models and static cell cultures. However, the concepts do not reliably replicate conditions of the human gut microenvironment to monitor in situ cell physiology. As a result, the mechanism of mercury transport in the human intestine is still unknown.

In a new report now published in Nature Microsystems and Nanoengineering, Li Wang and a research team in and in China developed a gut-on-a-chip instrument integrated with transepithelial electrical resistance (TEER) sensors and electrochemical sensors.

They proposed to explore the dynamic concept to simulate the physical intestinal barrier and mirror biological transport and adsorption mechanisms of mercury ions. The scientists recreated the cellular microenvironment by applying fluid shear stress and cyclic mechanical strain.

New nanowire sensors are the next step in the Internet of Things

Posted by in categories: biotech/medical, computing, internet, nanotechnology

A new miniscule nitrogen dioxide sensor could help protect the environment from vehicle pollutants that cause lung disease and acid rain.

Researchers from TMOS, the Australian Research Council Center of Excellence for Transformative Meta-Optical Systems have developed a sensor made from an array of nanowires, in a square one fifth of a millimeter per side, which means it could be easily incorporated into a silicon chip.

In research published in the latest issue of Advanced Materials, Ph.D. scholar at the Center’s Australian National University team and lead author Shiyu Wei describes the sensor as requiring no , as it runs on its own solar powered generator.

Brain Dead Vs. Coma Vs. Vegetative State: What’s The Difference?

Posted by in categories: biotech/medical, employment, neuroscience

In light of Whitney Houston and Bobby Brown’s daughter, Bobbi Kristina being found unconscious, there have been many headlines that said she in “a coma” or a “vegetative state” or even “brain dead”. First things first, patients who suffer brain death are not in coma. And patients who are in coma may or may not progress to brain death.

The brain has a number of vast jobs to complete every second and is a very complex organ. The brain controls not only an individual’s thought process and voluntary movements, but it controls involuntary movements and other vital body functions. These functions include auditory, olfactory, visual and tactile senses, regulation of body temperature, blood pressure, respiration, and heart rate (although the heart can continue to beat without the brain in “autotonic response”). The brain also produces hormones to control individual organ function. A good example is the brain’s production of anti-diuretic hormone (ADH). This hormone is produced to concentrate the urine in the kidneys, thus protecting against life-threatening dehydration.

How to Turn Air Pollution into Gleaming Diamonds

Posted by in categories: biotech/medical, finance

Year 2021 This also another use for air pollution into diamonds.


Mining diamonds is a notoriously destructive and exploitative process, both socially and environmentally. On a mission to produce diamonds sustainably and ethically, one company discovered a way to—quite literally—pull diamonds out of thin air.

According to the International Gem Society, 250 tons of soil are moved for each carat of mined diamond, wreaking havoc on ecosystems, wildlife, and the water table. Nearly 20 years have passed since the United Nations established the Kimberley Process, a certification to address human rights abuses in the mining industry and eradicate conflict diamonds from the global market. Also known as “blood diamonds,” conflict diamonds are mined in rebel-controlled areas and sold to help finance armed conflicts. The Human Rights Watch says that rebel rule, forced labor, and violence are still rampant in the industry.

A New Weapon Against Antibiotic-Resistant Bacteria

Posted by in categories: biotech/medical, health

UNIGE researchers have discovered that a medication commonly used to treat herpes can combat an antibiotic-resistant bacterium by disrupting its defense mechanisms.

Antibiotic resistance, or the ability of bacteria to develop resistance to treatment with antibiotics, has become a major concern for global health. The World Health Organization (WHO) considers it one of the greatest threats to health. The overuse of antibiotics has contributed to the emergence of antibiotic-resistant bacteria, which can cause serious illness and death. One example of an antibiotic-resistant pathogen is Klebsiella pneumoniae, a bacterium commonly found in hospitals and known for its virulence. Without effective treatment options, we could see a resurgence of diseases such as pneumonia and salmonella, which were once easily treated with antibiotics.

Researchers at the University of Geneva (UNIGE) have found that edoxudine, an anti-herpes molecule developed in the 1960s, can disrupt the protective surface of Klebsiella bacteria and make them more vulnerable to being eliminated by immune cells. The researchers’ findings were recently published in the journal PLOS ONE.
