EL PASO, Texas - Researchers in The University of Texas at El Paso's Department of Chemistry and Biochemistry have developed a nanohybrid vehicle that can be used to optimally deliver drugs into the human body.
The research was published in April 2020 in ACS Applied Materials & Interfaces. Leading the study are Mahesh Narayan, Ph.D., professor, and Sreeprasad Sreenivasan, Ph.D., assistant professor, both from the Department of Chemistry and Biochemistry and the Border Biomedical Research Center (BBRC) in UTEP's College of Science.
URBANA, Ill. - When the tree fell that October in 2015, the tropical giant didn't go down alone. Hundreds of neighboring trees went with it, opening a massive 2.5-acre gap in the Panamanian rainforest.
Treefalls happen all the time, but this one just happened to occur in the exact spot where a decades-long ecological study was in progress, giving University of Illinois researchers a rare look into tropical forest dynamics.
The high cost of testing cannabis in California leads to higher prices for the consumer, which could drive consumers to unlicensed markets.
A new study from researchers at the University of California, Davis, finds the safety tests cost growers about 10 percent of the average wholesale price of legal cannabis. The biggest share of this expense comes from failing the test.
Pancreatic cancer cells use a normal waste removal process to hide tags on their surfaces that would otherwise let the immune system destroy them, a new study finds. Published online April 22 in Nature, the study results help to answer a longstanding question: why are pancreatic cancers so resistant to immunotherapies, which use the body's own immune defenses to fight cancer?
A worldwide compilation of long-term insect abundance studies shows that the number of land-dwelling insects is in decline. On average, there is a global decrease of 0.92% per year, which translates to approximately 24% over 30 years. At the same time, the number of insects living in freshwater, such as midges and mayflies, has increased on average by 1.08% each year. This is possibly due to effective water protection policies. Despite these overall averages, local trends are highly variable, and areas that have been less impacted by humans appear to have weaker trends.
LEBANON, NH - Colorectal cancer is estimated to cause more than 53,000 deaths in the US in 2020, making it the second most common cause of cancer death. This death rate, however, has been steadily dropping, likely due to better cancer screening programs such as colonoscopy. During colonoscopies, clinicians excise colorectal polyps and visually examine them on histopathology slides for neoplasia. Detecting cancer at an early, curable stage and removing pre-invasive adenomas or serrated lesions ultimately reduces the mortality rate.
A new study led by scientists at the University of Birmingham has shed fresh light on how a key front-line drug kills the tuberculosis bacterium.
The research paves the way for development of new antibiotic drugs targeted at emerging strains of TB.
New research has heralded a promising step for sufferers of wheat sensitivity or allergy.
A joint project between Edith Cowan University (ECU) in Australia and CSIRO has revealed key insights about the proteins causing two of the most common types of wheat sensitivity - non-coeliac wheat sensitivity and occupational asthma (baker's asthma).
With an estimated 10 per cent of people suffering from wheat sensitivity or allergy causing a raft of chronic health issues, researchers are developing tests that will help the production of low-allergen wheat varieties in the future.
A new study from the University of Helsinki presents the current state of knowledge on the exposure and vulnerability of Indigenous Peoples to environmental pollution, reviewing the innumerable impacts that pollution poses on Indigenous communities from all over the world.
Telehealth delivery of dementia care in the home can be as effective as face-to-face home visit services if carers and recipients take advantage of the technologies available, Australian researchers say.
Dementia affects almost 50 million people worldwide, which is predicted to increase to 131.5 million people by 2050. Every three seconds someone in the world develops dementia.
A new study from Tampere University in Finland found that eye contact during video calls can elicit similar psychophysiological responses than those in genuine, in-person eye contact.
Antioxidants are one of the most interesting and widely investigated compounds in life sciences due to their key role in the protection of living systems from the negative effects of free radicals. A great variety of antioxidants and discoveries of new ones give opportunities to better understand their pathways and mechanisms of action. Furthermore, evaluation of the ratios of antioxidants in different samples (foods, herbs, pharmaceuticals, biological fluids, etc.) helps quality control and predicting of possible health effects.
Laboratory of Novice Magnet Materials working in collaboration with Spanish scientists (the University of Oviedo, Spain) tested the Preisach model using interfacing Fe-based microwires. This research was made to check whether it is applicable for FORC-analysis and how real-life conditions affect it.
Soft magnetic ferromagnetic microwires are used for magnetic field sensors, as well as for encoding and reading information. Such microwires are used, for example, for the implementation of 3D geolocation in gadgets, as well as for tagging commercial fish, etc.
Efforts to contain the spread of the Covid-19 pandemic are now the top priority of governments across the globe. As they make these life-saving decisions, it is particularly crucial for policymakers to accurately predict how the spread of the virus will change over time. Through research published in EPJ Plus, Ignazio Ciufolini at the University of Salento, and Antonio Paolozzi at Sapienza University of Rome, identify a clear mathematical trend in the evolution of daily new cases and death numbers in China, and use the same curve to predict how a similar slowdown will unfold in Italy.
B-cell acute lymphoblastic leukemia (B-ALL) is characterized by the accumulation of abnormal immature B-cell precursors (BCP) in the bone marrow (BM) and is the most common pediatric cancer. Among the different subtypes known in B-ALL, the most common one is characterized by the presence of a higher number of chromosomes than in healthy cells and is called High hyperdiploid B-ALL (HyperD-ALL). This genetic abnormality is an initiating oncogenic event affiliated to childhood B-ALL, and it remains poorly characterized.
