| Osmotic pressure and viscosity: Anticancer drug efficacy and restricting tumors using LDDS Posted: 29 Mar 2022 07:00 AM PDT Chemotherapy is known for its painful side-effects. It also has limitations when the cancer has metastasized to the lymph nodes. The lymphatic drug delivery system, where anticancer drugs are injected directly into the sentinel lymph nodes under ultrasound guidance, offers an alternative to conventional chemotherapy. Researchers have now found the optimal osmotic pressure and viscosity ranges, significantly improving the antitumor effect. |
| Heat storage: Scientists develop material that is stable, efficient and eco-friendly Posted: 29 Mar 2022 07:00 AM PDT A new heat storage material could help to significantly improve the energy efficiency of buildings. It can be used to store surplus heat and release it back into the environment when needed. Unlike existing materials, the new one can absorb significantly more heat, is more stable, and is made of harmless substances. |
| Residual water from the food industry gives seaweed cultivation a boost Posted: 29 Mar 2022 07:00 AM PDT Process water from the food industry is an excellent fertilizer in land-based seaweed cultivation. Not only does the seaweed grow faster; its protein content also multiplies. In this way, process water can go from being a cost to becoming a resource in the food industry. |
| An approach to treating a severe congenital myopathy Posted: 29 Mar 2022 07:00 AM PDT The diagnosis is rare, but devastating -- children with congenital muscle disorders often never learn to walk. Until now, there was no chance of recovery, but researchers are now presenting a possible therapeutic approach. |
| New estimation strategy improves soil carbon sampling in agricultural fields Posted: 29 Mar 2022 07:00 AM PDT Researchers have evaluated strategies for efficiently estimating soil organic carbon in agricultural fields. Quantifying soil organic carbon stocks in agricultural fields is essential for developing sustainable management practices and monitoring. The research team found that in a typical Midwestern agricultural field, public soil surveys and satellite imagery can be leveraged to efficiently select sample locations. This may reduce the number of samples needed to achieve a given precision (compared to random sampling). |
| I was here first! This is how hepatitis C inhibits hepatitis E Posted: 29 Mar 2022 06:07 AM PDT Infections with hepatitis C and E are so common that, going only by statistics, many people should be infected with both viruses at the same time. However, only very few such cases have been reported. A research team has a guess as to why this is the case: The researchers found that the viruses inhibit each other when they infect at the same time. |
| Posted: 29 Mar 2022 06:07 AM PDT Police and fire first responders are often first on the scene during an out-of-hospital cardiac arrest, and a new study finds that their intervention correlates with significantly higher chances of patient survival and hospital discharge with good neurological outcomes. Researchers say non-medical first responders are likely underutilized as lifesaving resources in these cases. |
| Rehabilitation psychologists: Specialists you may not yet know, but might one day need Posted: 29 Mar 2022 06:07 AM PDT Rehabilitation psychology is a field that focuses on assessing and treating cognitive, emotional and functional difficulties for patients in a rehabilitation setting. In a recent state of the field survey paper, researchers conclude that providers need to communicate the value they bring to organizations through saving costs from decreased hospitalizations, assessing the likelihood of successful interventions and recovery, and more. Authors also call for broad and simultaneous promotion and recruitment in the field. |

| Citizen science data are crucial to understand wildlife roadkill, demonstrates a study in Flanders Posted: 28 Mar 2022 10:37 AM PDT Researchers in Flanders (Belgium) analyzed roadkill records from the last decade in the region, using data provided by citizen scientists. Their study looks at the fate of 17 mammal species on the roads of Flanders. In the last decade, roadkill incidents there have diminished, but the exact reason is hard to pin down. The recorded observations, the scientists warn, 'are only the tip of the iceberg'. |
| Researchers use skull CT scans to estimate assigned sex at birth Posted: 28 Mar 2022 08:25 AM PDT Researchers have proposed a method of assigned sex estimation that is 'population-inclusive,' or one that did not inherently rely on any estimation of ancestry (population affinity) by using 3D volume-rendered computed tomography (CT) scans of ancestry skulls to estimate assigned sex at birth. |
| More older adults getting treated for substance abuse Posted: 28 Mar 2022 08:23 AM PDT The rates of older adults getting treatment for substance abuse rose sharply from 2000-2017, in tandem with the Baby Boom cohort reaching older adulthood. |
| Evidence of brain changes in those at risk of bipolar disorder captured with MRI scans Posted: 28 Mar 2022 06:20 AM PDT A study that showed changes in the brain in those at risk of developing bipolar disorder raises new hopes about early intervention. |
| Stroke treatments safe and effective for people with existing disability or dementia, study suggests Posted: 28 Mar 2022 06:00 AM PDT A research review found that clot-busting therapy and mechanical clot removal to treat ischemic stroke in people with a pre-existing disability or dementia was as safe and effective as in adults without those conditions. These treatments are key to preventing additional disability. A person's pre-existing disabilities or dementia may cloud the stroke assessment process, which may lead to clinicians thinking the stroke is more severe and beyond the window for optimal treatment. This often results in delayed treatment or no treatment. People with a disability or dementia should be included in randomized controlled trials for stroke treatment. Currently, evidence-based stroke treatment data and guidance for people with disability or dementia are extremely limited. |
