Combo pill alone and with aspirin lowers heart disease risk Posted: 13 Nov 2020 11:18 AM PST A 'polypill' is a single pill that includes multiple medications to control more than one health risk factor (such as heart disease, high blood pressure, high cholesterol, Type 2 diabetes, kidney disease, stroke). In this large, international trial, the polypill included blood pressure and cholesterol lowering medications for people at risk for heart disease. Results from the randomized, placebo-controlled trial show that the combination of a polypill plus aspirin reduced cardiovascular disease by 31%, and the polypill without aspirin reduced CVD by 21%. |
New cardiac arrest resuscitation treatment demonstrated 100% success rate in cannulation Posted: 13 Nov 2020 11:18 AM PST A new study found that the first four months of the Minnesota Mobile Resuscitation Consortium (MMRC) was 100% effective in cannulation for out-of-hospital sudden cardiac arrests. Cannulation is when tubes are placed in large veins and arteries in the legs, neck or chest in a patient by a health care provider. |
Promising MS drug may worsen disease Posted: 13 Nov 2020 11:18 AM PST The drug has not yet made it to human trials for multiple sclerosis, but scientists are urging their colleagues to move cautiously. |
The future's uncertain, but noradrenaline can help us adapt Posted: 13 Nov 2020 09:41 AM PST A brain chemical called noradrenaline is responsible for our responses to uncertain situations - helping us to learn quickly and adapt our behavior, a new study has found. |
Circular RNA regulates neuronal differentiation by scaffolding an inhibitory transcription complex Posted: 13 Nov 2020 09:40 AM PST In a screening for a functional impact to the neuronal differentiation process, researchers identified a specific circular RNA, circZNF827, which surprisingly 'taps the brake' on neurogenesis. The results provide an interesting example of co-evolution of a circRNA, and its host-encoded protein product, that regulate each other's function, to directly impact the fundamental process of neurogenesis. |
New green materials could power smart devices using ambient light Posted: 13 Nov 2020 09:40 AM PST Researchers have developed environmentally friendly materials that could harvest enough energy from indoor light to power wireless smart devices. |
A few kilograms weight loss nearly halves the risk of diabetes Posted: 13 Nov 2020 09:40 AM PST Losing a few kilograms in weight almost halves people's risk of developing Type 2 diabetes - according to a large scale research study. The research shows how providing support to help people with prediabetes make small changes to their lifestyle, diet and physical activity can almost halve the risk of developing Type 2 diabetes. The findings come from the largest diabetes prevention research study in the world in the last 30 years. The clinical trial involved >1,000 people with prediabetes. |
Computer vision app allows easier monitoring of diabetes Posted: 13 Nov 2020 09:40 AM PST A computer vision technology developed by engineers has now been developed into a free mobile phone app for regular monitoring of glucose levels in people with diabetes. |
East African Rift System is slowly breaking away, with Madagascar splitting into pieces Posted: 13 Nov 2020 09:40 AM PST The African continent is slowly separating into several large and small tectonic blocks along the diverging East African Rift System, continuing to Madagascar - the long island just off the coast of Southeast Africa - that itself will also break apart into smaller islands. |
Zinc-ion hybrid capacitors with ideal anions in the electrolyte show extra-long performance Posted: 13 Nov 2020 07:58 AM PST Metal-ion hybrid capacitors combine the properties of capacitors and batteries.
