In the framework of the Chlorella microalgae cultivation process, the researchers from Peter the Great St.Petersburg Polytechnic University (SPbPU) obtained microalgae biomass with a high content of carotenoid pigments, which is suitable for the food industry. The research results were published Nov. 2020 in the scientific journal "Agronomy Research".
Global greenhouse gas emissions over the last century have made southern China a hotspot for bat-borne coronaviruses, by driving growth of forest habitat favoured by bats.
A new study published today in the journal Science of the Total Environment provides the first evidence of a mechanism by which climate change could have played a direct role in the emergence of SARS-CoV-2, the virus that caused the COVID-19 pandemic.
Neanderthals' gut microbiota already included some beneficial micro-organisms that are also found in our own intestine. An international research group led by the University of Bologna achieved this result by extracting and analysing ancient DNA from 50,000-year-old faecal sediments sampled at the archaeological site of El Salt, near Alicante (Spain).
(Boston)--A new study recommends healthy children with symptoms of sleep disordered breathing, such as snoring or temporary cessation of breathing, should consider undergoing a sleep study (polysomnography) and should discuss the potential benefits of this with their pediatrician or otolaryngologist to possibly manage the child's symptoms medically and before surgery.
Gene expression is a highly regulated process, which involves several steps. These include transcription of DNA instructions into RNA, removal of non-coding segments from the RNA message, and its subsequent translation into proteins. All these steps involve specific molecular machineries responsible for conducting each process with high accuracy. The Galej group, based at EMBL Grenoble, studies the structure and function of the RNA-protein complexes that are involved in the regulation of gene expression.
The early prognosis of high-risk older adults for amnestic mild cognitive impairment (aMCI), using noninvasive and sensitive neuromarkers, is key for early prevention of Alzheimer's disease. A recent study, published in the Journal of Alzheimer's Disease, by researchers at the University of Kentucky establishes what they believe is a new way to predict the risk years before a clinical diagnosis. Their work shows that direct measures of brain signatures during mental activity are more sensitive and accurate predictors of memory decline than current standard behavioral testing.
USC researchers have developed a new method to counter emergent mutations of the coronavirus and hasten vaccine development to stop the pathogen responsible for killing thousands of people and ruining the economy.
Using artificial intelligence (AI), the research team at the USC Viterbi School of Engineering developed a method to speed the analysis of vaccines and zero in on the best potential preventive medical therapy.
SSRgenotyper is a newly developed, free bioinformatic tool that allows researchers to digitally genotype sequenced populations using simple sequence repeats (SSRs), a task that previously required time-consuming lab-based methods.
Reporting in a recent issue of Applications in Plant Sciences, the tool's developers designed the program to seamlessly integrate with other applications currently used for the detection and analysis of SSRs.
The group led by Dr. Enrique J. Calderón - "Clinical Epidemiology and Vascular Risk" at the Institute of Biomedicine of Seville - IBiS/University Hospitals Virgen del Rocío and Macarena/CSIC/University of Seville, also a member of CIBERESP, participated in a project with researchers from CIBER-BBN, in which they developed systems to detect Pneumocystis jirovecii, an atypical fungus responsible for very severe pneumonia in immunosuppressed patients.
In-silico modelling helps with the integrated study of the intervertebral disc in health and disease
The spinal column consists of 24 vertebrae that provide axial support to the torso and protection to the spinal cord that runs through its central cavity. The vertebrae are connected by means of intervertebral discs. These discs are highly hydrated, flexible and highly mechanically resistant. They allow the column its flexibility and act as shock absorbers during daily activities such as walking, running and in impact situations, such as jumping.
What is common between a technology for storing energy in a solar cell and that for water purification? They both rely on the use of porous materials, or more specifically, "nanoporous" materials that can trap gas molecules within narrow spaces on their surface, called "pores", which are only nanometers (one-billionth of a meter) in size! In chemistry parlance, the phenomenon is known as "adsorption" and has played an important role in the synthesis of porous materials of different compositions, pore sizes, and even pore geometries.
Treating severe COVID-19 patients with the anticancer drug bevacizumab may reduce mortality and speed up recovery, according to a small clinical study in Italy and China that was led by researchers at Karolinska Institutet in Sweden between February and April 2020. On average, blood oxygen levels, body temperature and inflammatory markers significantly improved in patients treated with a single dose of bevacizumab in addition to standard care. The research is published in Nature Communications.
A research team led by Prof. HE Shunping from the Institute of Hydrobiology (IHB) of the Chinese Academy of Sciences has discovered through genome sequencing that the non-teleost ray-finned fishes--bichir, paddlefish, bowfin and alligator gar--exhibit mosaic genomic features of lobe- and ray-finned fishes. The study was published in Cell.
Using patient data, artificial intelligence can make a 90 percent accurate assessment of whether a person will die from COVID-19 or not, according to new research at the University of Copenhagen. Body mass index (BMI), gender and high blood pressure are among the most heavily weighted factors. The research can be used to predict the number of patients in hospitals, who will need a respirator and determine who ought to be first in line for a vaccination.
When treating cancer, researchers are always searching for ways to remove cancer cells while minimizing damage to the rest of the body. One possible approach is to find processes unique to cancer cells, and which would allow specific targeting. If such a process can be disrupted, only those cells would be affected.
