Scientists regenerate neurons in mice with spinal cord injury and optic nerve damage

Each year thousands of patients face life-long losses in sensation and motor function from spinal cord injury and related conditions in which axons are badly damaged or severed. New research in mice shows, however, that gains in functional recovery from these injuries may be possible, thanks to a molecule known as Lin28, which regulates cell growth.

Better understanding of nature's nanomachines may help in design of future drugs

Many of the drugs and medicines that we rely on today are natural products taken from microbes like bacteria and fungi. Within these microbes, the drugs are made by tiny natural machines known as nonribosomal peptide synthetases (NRPSs). A research team has gained a better understanding of the structures of NRPSs and the processes by which they work. This improved understanding of NRPSs could potentially lead to the creation of new potent antibiotics, immunosuppressants and other modern drugs.

An international study has concluded that, in general, there is no correlation between costs of a cancer drugs and their clinical benefit. The researchers are therefore calling for the clinical benefit of drugs to be better reflected in pricing.

The discovery of general anesthetics -- compounds which induce unconsciousness, prevent control of movement and block pain -- helped transform dangerous operations into safe surgery. But scientists still don't understand exactly how general anesthetics work. Now, researchers have revealed how a general anesthetic called isoflurane weakens the transmission of electrical signals between neurons, at junctions called synapses.

Traffic officer protein governs speed of sugar/fat conversion pathway

Structure of biocatalysts depends on whether they are in cells or test tubes

The structure of enzymes determines how they control vital processes such as digestion or immune response. This is because the protein compounds are not rigid, but can change their shape through movable 'hinges.' The shape of enzymes can depend on whether their structure is measured in the test tube or in the living cell. This is what physicochemists discovered about YopO, an enzyme of the plague pathogen.

Syphilis eludes immune attack by altering a single gene

Shuffling of DNA in a single gene might be why the syphilis bacteria can evade the immune system. The change alters a protein on its cell surface to create a distraction. People can become re-infected several times with syphilis because they can't develop immunity, Untreated syphilis can hide in the body for decades. Genomic findings on these evasive strategies may point to designs for vaccines to outwit syphilis' defenses.

Breakthrough discovery in HIV research opens path to new, better therapies

Cells infected with HIV make two forms of the virus's RNA. A new article finds a single nucleotide controls which version of viral RNA an infected cell makes; both forms are necessary for HIV to replicate. The critical nucleotide happens to be in a region of the HIV genome with low mutation rates. That placement makes it a promising target for new therapies, because the virus is less likely to develop resistance.

Scientists show that when a molecule known as c-Jun N-terminal kinase (JNK) becomes active in sepsis, it increases the production of a protein called B-type natriuretic peptide (BNP) -- the more BNP that is produced in sepsis, the greater the deterioration of cardiovascular function. But perhaps more significantly, in mice, the researchers show that JNK and BNP activity can be halted, reversing cardiovascular damage and reducing the risk of death from sepsis.

The sensation of sweetness starts on the tongue, but sugar molecules also trip sensors in the gut that directly signal the brain. This could explain why artificial sweeteners fail to satisfy the insatiable craving for sugar.

Researchers restore sight in mice by turning skin cells into light-sensing eye cells

Researchers have discovered a technique for directly reprogramming skin cells into light-sensing rod photoreceptors used for vision, sidestepping the need for stem cells. The lab-made rods enabled blind mice to detect light after the cells were transplanted into the animals' eyes.

Crohn's disease: Preserving inflammation-free phases

Crohn's disease is a chronic inflammatory disorder of the intestine that, in most cases, relapses episodically. As of now, there is no cure for this disease. A research group has discovered a marker at a microscopic level, which can be used to identify patients that show a high probability of suffering from an inflammation recurrence in the immediate future. With this insight, therapeutic counter-measures may be employed at an earlier stage.

New textile could keep you cool in the heat, warm in the cold

Imagine a single garment that could adapt to changing weather conditions, keeping its wearer cool in the heat of midday but warm when an evening storm blows in. In addition to wearing it outdoors, such clothing could also be worn indoors, drastically reducing the need for air conditioning or heat. Now, researchers have made a strong, comfortable fabric that heats and cools skin, with no energy input.

Alzheimer's patients may need dosing changes in medicines prescribed for other conditions

Patients with Alzheimer's disease (AD) are often prescribed drugs for other conditions -- including diabetes or high blood pressure -- at the same doses as those without dementia. That practice might need to be reexamined in the wake of new mouse studies. The findings suggest that AD could alter absorption of medications from the digestive tract, so dosages might need to be adjusted for these patients.

How probiotic Bifidobacteria could help celiac disease patients

Gluten is enemy No. 1 for those with celiac disease, and it's hard to avoid. Episodes of this chronic autoimmune illness can be triggered by ingesting gluten, a key protein in wheat and some other grains. Researchers have been exploring how gut bacteria, especially Bifidobacteria, could be used as a treatment. Now, scientists report how specific types of Bifidobacteria work.

COPD as a lung stem cell disease

Two stem cell researchers have found an abundance of abnormal stem cells in the lungs of patients who suffer from Chronic Obstructive Pulmonary Disease (COPD), a leading cause of death worldwide. The team, who used single cell cloning of lung stem cells to make their discovery, is now targeting the cells for new therapeutics.

A more plant-based diet without stomach troubles: Getting rid of FODMAPs with enzymes

A plant-based diet is a good choice for both climate and health. However, many plant-based products, especially legumes, contain FODMAP compounds that are poorly digestible and cause unpleasant intestinal symptoms. A study has succeeded in breaking down FODMAPs with enzymes and producing new, stomach-friendly plant-based food products.

Heavy wildfire smoke may raise the risk of out-of-hospital cardiac arrest. To reduce exposure to wildfire smoke, researchers advise people to stay indoors with doors and windows closed, to use high-efficiency air filters in air conditioning systems, avoid exertion, and consider seeking shelter elsewhere if the home does not have an air conditioner and it is too warm to stay inside.

Being right-brained or left-brained comes down to molecular switches

Scientists may have solved one of the most puzzling and persistent mysteries in neuroscience: why some people are 'right-brained' while others are 'left-brained.' The answer lies in how certain genes on each side of the brain are switched 'on' and 'off' through a process called epigenetic regulation. The findings may explain why Parkinson's disease and other neurological disorders frequently affect one side of the body first, a revelation that has far-reaching implications for development of potential future treatments.

How cells recognize uninvited guests

Until now, the immune sensor TLR8 has remained in the shadows of science. A research team has now discovered how this sensor plays an important role in defending human cells against intruders. The enzymes RNaseT2 and RNase2 cut ribonucleic acids (RNAs) of bacteria into small fragments that are as characteristic as a thumbprint. Only then can TLR8 recognize the dangerous pathogens and initiate countermeasures.
