Researchers have developed a shoe insole that could help make the healing process more portable for people who develop ulcers as a result of diabetes.
Diabetic ulcers commonly result from high blood sugar damaging nerves, which takes away feeling from the toes or feet.
“One of the ways to heal these wounds is by giving them oxygen,” said Babak Ziaie, Professor at the Purdue University in the US.
“We’ve created a system that gradually releases oxygen throughout the day so that a patient can have more mobility.”
Without the ability to feel pain, hits and bumps tend to go unnoticed and skin tissue breaks down, forming ulcers.
A lot of sugar in the bloodstream, along with dried skin as a result of diabetes, further slow the ulcer healing process.
The researchers used lasers to shape silicone-based rubber into insoles, and then create reservoirs that release oxygen only at the part of the foot where the ulcer is located.
“Silicone is flexible and has good oxygen permeability,” said Hongjie Jiang, a post-doctoral researcher at the varsity.
“Laser machining helps us to tune that permeability and target just the wound site, which is hypoxic, rather than poison the rest of the foot with too much oxygen,” Jiang added.
In a paper published in the journal Materials Research Society Communications, the team said the insole can deliver oxygen at least eight hours a day under the pressure of someone weighing about 53-81 kg.
It can also be customised to take on any weight, the study said.
The team envisions a manufacturer sending a patient a pack of pre-filled insoles customised to his or her wound site, based on a “wound profile” obtained from a doctor’s prescription and a picture of the foot.
“This is mass-customisation at low cost,” said Vaibhav Jain, research associate at Purdue.
A patent is pending on the insole technology. The team is currently seeking corporate partners. (IANS)
With Diwali comes the yearly ritual of disinfectingand deep-cleaning our homes. However, your basic cleaning ritual might not be sufficient to the changing needs of the environment we live in. If the deadly viruses around us have taught anything, disinfection should be as much a goal in our regular cleaning, rather than just the basic visible cleanliness. Therefore, it becomes necessary to know the right way of cleaning and disinfectinghomes that lends itself to a responsible celebration. While we plan to welcome Goddess Lakshmi by cleaning and decorating our living spaces inside out, we should be aware of those corners that are prone to infections, diseases and require our special attention.
The R&D team at ITC Savlon, shares some tips to maximize hygiene and ensure germ-free cleaning this Diwali:
Clean your Kitchen
As the excitement builds for us to be able to open our houses to guests and have the kitchen work overtime to put out scrumptious meals, do spend a moment on considering thorough kitchen disinfection. Bear in mind that the multiple ways in which we use our home kitchen carry with it the burden of microbes that can cause infections.
A disinfection ritual will ensure that any chances of microbial contamination to your person or to the food being cooked gets eliminated. Be it organizing shelves and arranging jars, wiping the crockery cabinet, or cleaning the refrigerator, all you need is a multipurpose disinfectant and cleaner by your side. A Spray & Wipe Multipurpose disinfectant cleaner that is readily available makes the task of cleaning convenient with its dual action of cleaning and disinfection together. The added feature of a citrus fragrance also helps keep the space smelling fresh.

Refresh your Bathroom
When we spruce up our homes around Diwali, we often forget to place our bathroom hygiene on the priority list. Bathrooms are breeding corners for germs and harmful microorganisms. As we accommodate our guests for a get-together or a game of cards, let's also keep in mind that bathrooms are the second most used space by guests. It becomes crucial, therefore, to effectively clean our restrooms and keep them dry. Make sure you buy a multipurpose disinfectant to clean the floor, wipe the washbasin, and faucets, or other frequently touched areas. Add a scented candle of a fragrance diffuser with some essential oil poured in to uplift the space and leave it smelling fragrant.

Style your Living room
We often indulge in renovating your living areas just before Diwali, but there are other comparatively smaller purchases that might help you bypass an overhaul. One can brighten up living spaces with new drapes and bright-coloured cushions giving a cozy look to your favourite couch. At times, buying new furniture, sofas, etc. gets beyond budget, so indulge in fabric covers instead. They give your existing furniture a great face-lift. You could also look at rearranging the furniture placement and adding new wall art. Simple additions like this often give the entire space a new look. While you move around the furniture or add new drapes, make sure you spray them down with a surface disinfectant spray regularly since they are not washed as frequently. Spray Surface Disinfectant Spray post dusting to kill 99.9 per cent of germs. This helps you, welcome guests, to a safe environment and a quick spray after the party winds down, ensures you and your family also stay protected.

According to WHO -- if hand hygiene is done properly this can be over 90 per cent effective in preventing the spread of harmful germs and HCAIs. So, let's ensure to keep our hand hygiene at par by washing hands regularly and wiping down doorknobs, spraying playing cards, or serviette holders with a disinfectant from time to time.
As we get excited to meet our friends, families this festive season we must be cautious while doing handshakes, exchanging high-fives etc. to control the germ transmission. | Photo by Kaffeebart on Unsplash
As we get excited to meet our friends, families this festive season we must be cautious while doing handshakes, exchanging high-fives etc. to control the germ transmission. This can be done by replacing towels with tissue papers in the guest bathroom so that no two people use the same towel. Another way is by placing hand sanitizer bottles that could be accessible for guests enabling them to use it as and when required.

Birbal, an intelligent and witty man, was a beloved courtier to Emperor Akbar. He was one of the youngest men of the court, who had the greatest influence on the ruler. Despite his Hindu background, he supported the Mughal ruler and even adopted Din-i-ilahi towards the end of his life. He died in a battle that he led against a rebel army. He belonged to the precious nine courtiers of Akbar's court known as the Navratnas (nine gems).
Born as Mahesh Das, Birbal was renamed in Akbar's court. He solved many petty issues with his wit and is known as a man of practical wisdom. He lives on today in the literature that shapes children's formative years, in application comedy for adults, and in folktales for everyone else. His wisdom is so unique and so practical that it does not take too much to understand it. At the same time, it is not something that can be easily emulated.
There are certain instances where Birbal's wit is not entirely useful, nonetheless, it provides for a good laugh. As a man who set out to make a change in the world, particularly in a king's court, he is a man who has left a rather impressive legacy for humility, loyalty, and unbounded talent. Although his position in the court was perhaps far more important than that of a jester, he is portrayed as one, and this remains for centuries.
He lives on in the tales of grandparents, in moral science textbooks for young children, and sometimes unconsciously in the decisions that we take daily. Many of the stories we have heard ourselves through various sources remain with us and reflect in the way we look at situations and understand their outcomes.
Birbal, as a character in a story, will not die away anytime soon. As a stalwart for common sense, and a symbol of exercising the innate ability to reason everyday phenomena, he will remain immortal in literature. Children of today and those of tomorrow will surely never tire of reading about him and his marvellous witticisms.

Just as much as man has evolved from the time of the nomads, his practices and rituals have grown more and more sophisticated. With time, things that once were just formalities have acquired ritual significance and are observed in solemnity. Death was once something that marked the end, but now is an important life change event that is memorialized. Some people come alive only after death.
In nomadic times, men buried their dead companions or family along the route they traveled. They would place a stone or any heavy object over it, to prevent the soil from becoming loose around the body, or to keep it safe from scavengers. This practice is no longer followed as the animal kingdom and man's world have become distinct from each other.
Europe is dotted with Stonehenge clusters, which are historical pieces of evidence of human progress. It is a keen and detailed system that human ancestors devised for burying their dead. Carbon dating suggests the presence of decomposed remains, but its actual significance is speculated.
The Egyptians devised building pyramids in which they laid their dead. They are one of the earliest civilizations to propagate the idea of an afterlife. They filled the pyramids with earthly treasures, all of which they believed were required in the next life.

When devastating plagues hit countries, the dead were buried in masses. Walls were built around these sites to contain the dead bodies and to prevent them from spilling out. Later superstitions and folklore about the 'undead' forced people to place crosses and crucifixes on graves to keep their loved ones from turning into blood-sucking vampires. Sometimes, coffins were pierced in the centre with a large stake to prevent the deceased from waking up again. Gravestones were laid to make sure that the person did not escape. Sometimes, an intact gravestone was an indicator of a pure soul.
The Renaissance instilled a scientific spirit of inquiry, which caused brilliant advancements in every field, but this came at rather bizarre costs. Students of human anatomy needed a basis for their theories and were often found vandalizing property, digging up the dead to use for dissection. Laws were passed against this, but it was a practice that prevailed. Some of the most famous principles of medicine come from this era.
Burying the dead has changed so much with the times. Today's practice of laying gravestones has no preventive measures like those in the past. Instead, they serve to immortalize the dead. It is to fulfill the life of the person by laying them to rest in their final earthly abode and leaving behind a marker of their life either by a symbol, a quote, or a verse that best describes them. As the population of the world continues to grow, land space for burial is growing scarce, and gravestones are now becoming a rare privilege.
