A Magic Gel Could Save Amputations for Diabetics now.

 Millions of diabetics live in fear of a wound that won’t heal. One bad cut can cost a limb.

UC Riverside created a gel that delivers a continuous flow of oxygen directly into the deepest layers of injured tissue using a tiny battery-powered system. Chronic wounds spiral out of control because oxygen can’t reach where it’s needed. This gel fixes that.

No surgery. No skin grafts. Just a gel that breathes life into dying tissue.
Diabetes affects 537 million people. This could save millions of them from amputation.

Simple test may predict preterm births

Researchers have found that a simple test of cervical mucus may reveal pregnant women’s risk of going into labour too early. Up to 18 per cent of babies born worldwide arrive before they are full-term, defined as 37 weeks of gestation. The study, showed that cervical mucus from women who delivered their babies before 37 weeks was very different from that of women who delivered later. This type of analysis could offer an easy way to calculate the risk of early labor, potentially allowing doctors to try to intervene earlier to prevent preterm births.

 “Our prediction is that we might be able to identify risk for preterm birth ahead of time, before labour sets in,” said senior author of the study. Between 25 and 40 per cent of early births are believed to be caused by infections that occur when microbes reach the uterus through the cervical plug, which is made of mucus and normally blocks access to the uterus. For the new study, the researchers decided to investigate the mucus’s permeability to small particles. Mucus is formed from polymers known as mucins, and the composition and arrangement of these mucins determine how porous the gel is.

The researchers collected samples from two groups of patients. The low-risk group included pregnant women who came in to their doctors’ offices for routine visits around 30 weeks and ended up giving birth after 37 weeks.  The high-risk group included women who went into labor early, between 24 and 34 weeks. Doctors were able to halt labour in these women, and the samples were taken after they were stabilised. They all ended up giving birth before 37 weeks.

The researchers found a significant differences in mucus permeability and adhesiveness – the peptides were able to pass through samples from high-risk women much more easily. This suggests that cervical mucus from women at high risk for early labour, for reasons not yet known, may be more susceptible to invasion by potentially harmful bacteria and microbes, making it more likely that those women will experience an infection that leads to preterm birth, the researcher said.

In addition, the altered mucus may be less able to retain helpful immune system components such as antibodies or antimicrobial peptides, which would normally help to combat infection, the study said. The researcher anticipates that cervical mucus testing could be done early in pregnancy, as part of a routine screen that would reveal whether a woman was at high risk of preterm birth.

Soon, gel implant to fight diabetes

Scientists have developed an implantable gel that contains genetically modified light-sensitive cells and it can be used to treat diabetes.

Researchers have designed an implantable gel that guided light under a mouse's skin in experiments.

To control diabetes, the team shone light into the mouse and at the implanted gel using a fibre optic cable attached to its head.

The light triggered cells in the gel to produce a compound that stimulated the secretion of insulin and stabilised blood glucose levels, it was reported.

The team also showed they could monitor for cadmium poisoning using cells that fluoresced when the mouse was under stress from the toxin.

The gel is in the prototype stage but the team is already planning to make it more user-friendly.

For example, he said, "we are thinking of adding a micro-LED with a wireless power receiver [to the gel implant]."

tooth paste for hair !

Keep hair in place. Gel toothpastes contain the same water-soluble polymers that many hair gels are made of. If you’re looking to style and hold an extreme hair creation, try gel toothpaste as your go-to product if you’re out of regular hair gel. (This is also a great trick for making baby barrettes stay in place.)
