| Researchers find immune component to rare neurodegenerative disease Posted: 21 Jul 2021 02:27 PM PDT Researchers have identified an immune protein tied to the rare neurodegenerative condition known as Niemann-Pick disease type C. The finding, made in mouse models, could offer a powerful new therapeutic target for Niemann-Pick disease type C, a condition that was identified more than a century ago but still lacks effective treatments. |
| New study confirms relationship between toxic pollution, climate risks to human health Posted: 21 Jul 2021 02:27 PM PDT In a new study that combines assessments of the risks of toxic emissions, nontoxic emissions and people's vulnerability to them, researchers found a strong and statistically significant relationship between the spatial distribution of global climate risk and toxic pollution. |
| Ibrutinib effective treatment for difficult-to-treat forms of hairy cell leukemia, study finds Posted: 21 Jul 2021 11:19 AM PDT The oral targeted therapy drug ibrutinib is an effective treatment option for high-risk hairy cell leukemia, according to a new study. |
| Study links vaccine immune response to age Posted: 21 Jul 2021 11:19 AM PDT Older people appear to have fewer antibodies against the novel coronavirus, a new laboratory study suggests. With vaccine uptake slowing in Oregon and across United States, researchers say their findings underscore the importance of promoting vaccinations in local communities. |
| Chromosomes separation under focus Posted: 21 Jul 2021 11:19 AM PDT During cell division, chromosomes are duplicated and separated so that one copy of each chromosome is inherited by each of the two emerging daughter cells. Correct distribution of chromosomes requires high accuracy and defects in this process can cause aberrant distribution of chromosomes and facilitate cancer development. By analyzing the structure of the protein responsible for chromosome separation, a team has shed light on the mechanisms controlling this essential player in cell division. |
| Thumb-sized device quickly 'sniffs out' bad breath Posted: 21 Jul 2021 09:07 AM PDT Researchers have constructed a portable, thumb-sized device that diagnoses bad breath by quickly 'sniffing' exhalations for the gas that makes it stinky -- hydrogen sulfide. |
| Toward one drug to treat all coronaviruses Posted: 21 Jul 2021 09:07 AM PDT Researchers have analyzed viral proteins across 27 coronavirus species and thousands of samples from COVID-19 patients, identifying highly conserved sequences that could make the best drug targets. |
| Breakthrough in detection of SARS-CoV-2 variant in wastewater Posted: 21 Jul 2021 09:07 AM PDT Researchers have developed an innovative method to detect and quantify the more transmissible B.1.1.7 (Alpha) variant of concern via wastewater epidemiology. |
| Wearable brain-machine interface turns intentions into actions Posted: 21 Jul 2021 09:06 AM PDT An international team of researchers is combining soft scalp electronics and virtual reality in a brain-interface system. |
| Toxicity testing on the placenta and embryo Posted: 21 Jul 2021 09:06 AM PDT Researchers have developed a cell culture test to detect substances that are directly or indirectly harmful to embryos. Based on an existing test used for developing new drugs and chemicals, the augmented version is designed to help reduce the number of animal experiments. |
| Advancing the long-term well-being of people living with HIV Posted: 21 Jul 2021 09:06 AM PDT A global multidisciplinary group of HIV experts has developed a consensus statement identifying the key issues health systems must address in order to move beyond the longtime emphasis on viral suppression to instead deliver integrated, person-centered healthcare for people living with HIV throughout their lives. |
| New method predicts COVID-19 severity, could help with hospital triage Posted: 21 Jul 2021 09:06 AM PDT Researchers have developed a blood test to predict which people infected with COVID-19 are most likely to experience serious symptoms, which could help health care workers prioritize patients for hospitalization and intensive care. |
| Breastfeeding, even for a few days, linked to lower blood pressure in early childhood Posted: 21 Jul 2021 07:24 AM PDT Babies who were breastfed, even for a few days, had lower blood pressure at 3 years of age than children who had never been breastfed. Toddlers who had been breastfed had lower blood pressure regardless of their body mass index or their mothers' social, health or lifestyle factors. |
| Cognitive decline may help predict future fracture risk in women Posted: 21 Jul 2021 07:24 AM PDT A 16-year study has revealed a link between cognitive decline, bone loss and fracture risk in women. |
| Residential proximity to oil and gas drilling linked to lower birthweights in newborns Posted: 21 Jul 2021 07:23 AM PDT A new study has found that infants born within three kilometers of oil and natural gas drilling facilities in Texas had slightly lower birthweights than those born before drilling began in their vicinity. |
| C is for Vitamin C -- a key ingredient for immune cell function Posted: 21 Jul 2021 07:23 AM PDT Regulatory T cells (Tregs) help control inflammation and autoimmunity in the body. Unfortunately, it has proven difficult to find the right molecular ingredients to induce stable iTregs. Now a new study reports that Vitamin C and TET proteins can work together to give Tregs their life-saving power. |
| Blocking how the malaria parasite suppresses the immune response Posted: 21 Jul 2021 07:23 AM PDT The parasites that cause severe malaria are well-known for the sinister ways they infect humans, but new research may lead to drugs that could block one of their most reliable weapons: interference with the immune response. |
| Smartphone gaming can be harmful for some seeking relief from boredom, study finds Posted: 21 Jul 2021 07:23 AM PDT Smartphone gaming can be harmful to players who game to escape their negative mood and feelings of boredom, a new study has found. |
| Novel method predicts if COVID-19 clinical trials will fail or succeed Posted: 21 Jul 2021 07:23 AM PDT Researchers have modeled COVID-19 completion versus cessation in clinical trials using machine learning algorithms and ensemble learning. |
| Scientists link frailty and neurocognitive decline in childhood cancer survivors Posted: 21 Jul 2021 07:23 AM PDT Scientists have shown that frailty contributes to neurocognitive decline in young adult survivors of childhood cancer. |
| Nanoparticles create heat from light to manipulate electrical activity in neurons Posted: 21 Jul 2021 07:23 AM PDT Engineers developed technology to use nanoparticles to heat, manipulate cells in the brain and heart. |
| Effectiveness of mRNA vaccines against the Alpha and Beta variants in France Posted: 21 Jul 2021 07:22 AM PDT In a new study, scientists show that the two-dose vaccination regimen of mRNA vaccines provides 88 percent protection against non-variant virus, 86 percent against the Alpha variant, and 77 percent against the Beta variant. |
| Cancer: Information theory to fight resistance to treatments Posted: 21 Jul 2021 07:22 AM PDT A major challenge in cancer therapy is the adaptive response of cancer cells to targeted therapies. Although this adaptive response is theoretically reversible, such a reversal is hampered by numerous molecular mechanisms that allow the cancer cells to adapt to the treatment. A team has used information theory, in order to objectify in vivo the molecular regulations at play in the mechanisms of the adaptive response and their modulation by a therapeutic combination. |
| Many ICU staff have experienced mental health conditions in COVID-19 pandemic Posted: 21 Jul 2021 07:22 AM PDT A high proportion of staff working in intensive care units during the COVID-19 pandemic have experienced mental health conditions, according to a new study. |
| SARS-CoV-2 variant B.1.617 gives the immune system a hard time Posted: 21 Jul 2021 07:22 AM PDT Researchers have investigated the SARS-CoV-2 variant B.1.617 in detail. In cell culture studies, they found that this variant can infect certain lung and intestinal cell lines more efficiently than the original virus. The researchers also demonstrated that B.1.617 is less sensitive to inhibition by antibodies present in the blood of convalescent or vaccinated individuals and resistant to a therapeutic antibody used for COVID-19 treatment. |
