The pigs survived the surgery
Anastomosis is performed more than a million times each year in the United States, for surgery involving the intestines, as well urologic and gynecologic operations."If you have a more consistent and a more, well-tensioned, evenly spaced suture around this garden hose, it’s going to be able to withstand a higher burst pressure," Decker said.
The study showed STAR outperformed expert surgeons and a well-known robotic surgery tool already on the market, called the da Vinci robot, which is held in the surgeon’s hand and used to perform surgeries such as hysterectomies through a few small incisions."That’s in fact what happened with our anastomosis.Researchers stressed that surgeons were keeping a close eye on the machine as it worked, and it could be quickly stopped if any error were to occur.Soft tissue is particularly complicated because it is malleable and moveable. Researchers expect there will be a need for clinical trials to assess its safety in humans before it can approved by regulators. (Photo: AP)A robotic machine has succeeded at stitching two segments of a pig’s bowel together, an advance for the tricky field of soft tissue surgery, researchers said on Wednesday..The STAR system is likely years away from widespread use.But being able to improve on such surgeries "could potentially reduce complications and improve the safety and efficacy of soft tissue surgeries, about 45 million of which are performed in the US each year," according to the study led by doctors at the Children’s National Health System in Washington, DC and Johns Hopkins University in Baltimore, Maryland. They were able to withstand a higher burst pressure than surgeons performing the same task.The STAR was tested on a procedure called anastomosis, which comes after a surgeon has cut open the patient’s body and completed the main goal of the surgery — for instance by removing a tumour from the bowel — and is then reconnecting two sections, "like trying to put together a garden hose, which has been cut," explained co-author Ryan Decker."
The pigs survived the surgery and showed no complications a week later. For the current study, surgeons made fluorescent markings on the vessels to be sewn, and the robot followed them, showing it could make more consistent and evenly spaced stitches, or sutures, than a human surgeon, Decker told reporters.Until now, robotic surgeries have largely relied on the expertise of the surgeon and outcomes have varied according the doctor’s skill, researchers say.This photo provided by Axel Krieger/Science Translational Medicine shows Dr Azad Shademan and Ryan Decker during supervised autonomous in-vivo bowel anastomosis performed by the smart tissue autonomous robot.The machine, called the Smart Tissue Autonomous Robot (STAR), does not replace the need for a skilled surgeon, but acts as a tool to improve the accuracy of stitching, said the report in the journal Science Translational Medicine.As many as 30 per cent of gastrointestinal anastomoses "are complicated by leakage, strictures, and stenosis," according to a statement from the Children’s National grain grinder machine for sale Health System.

Put spices in the center
Take the case of South India — "We drink something warm before our meal to aid digestion, hence rasam and even sambhar is consumed piping hot to maintain a warm temperature in the stomach which helps the process of extracting nutrition from food. Post that, you can add any acid like tamarind water or tomato puree.Add chicken shorba. Bring to a boil.Make a bouquet garni (potli) of cinnamon, black peppercorns, fennel, cloves and black cardamom.
In its original form, Mulligatawny is made from chicken or lamb broth, fried onions and curry powder," says Chef Nadeem Qureshi, Executive Chef, Soma, Grand Hyatt, Mumbai. Cover and simmer for 20 minutes or till chicken is soft.For Shorba — Step 2Heat ghee in a pan. Set the shorba aside. Bring to a boil. Fry mutton on high heat for 4-5 minutes. Add cumin seeds and mutton. Mix well and boil it. Once you have the base ready, add whole spices like pepper, cumin and cloves. Continue to simmer for 15 minutes more, till the mixture becomes soft. Now cut the tomatoes into big pieces, slice the onions, and crush the ginger and garlic cloves using a mortar and pestle. Sauté till a fine aroma is emitted. Sauté this mixture for 2-3 minutes. Open the pan and let the soup cool. Lower the heat.Indian cuisine doesn’t really have a soup culture unlike its Western counterpart. Cover and simmer on medium heat for 50 minutes. Historically, South India is popular for rasam and its many variants are popularly consumed as a soup," says Chef Dharmesh Karmokar, Chef and co-owner of Thangabali Restaurant in Mumbai that specialises in cuisine from the kitchens of South India."Hence, you will see tamarind, kokum and tomato being used as a base along with lentils for the body.Badami Murgh ShorbaIngredients:Chicken with bone: 300gmFor Spice PotliFine cloth: 1Saunf: 2 tbspCinnamon stick: 3 inch piece, broken in halfCloves: 8Black cardamom: 5, cracked openBlack peppercorn: 10Bay leaf: 2Cumin seeds: 1 tspCoriander seeds: 2 tspFor SoupWater: 4 cupsGhee: 3 tbspOnions: 3/4 cup, finely choppedGarlic: 1 tbsp, mincedGinger: 1 inch piece, finely choppedTurmeric powder: ¼ tspCayenne pepper powder as per tasteAlmond- 100gm pasteDried fenugreek leaf: ½ tspBengal gram powder: 2 tbspSalt as per tasteMethod:Clean the chicken and debone. Indian soups are even more helpful in fighting cold and cough as we often use coconut oil which contains the magic element — sodium monolauric, the base of the human immune system.
Pressure cook till mutton is nicely done. "Therefore, the body of the soup tends to be lighter and tangier with the addition of souring agents instead of heavy creams and flour-based sauces," explains Karmokar. Sauté for about 2 minutes.For Shorba — Step 1Heat ghee in a heavy bottomed pan.Recipe for a quick and easy rasam — Heat coconut oil and add mustard seeds, garlic, curry leaves and hing. Set aside. Gather edges and tie a string around it. The name originates from the Tamil words mullaga/milagu and thanni, which translates into "pepper-water".Add turmeric powder, salt, cayenne powder and kasoori leaves.Fold cloth in half.Add whisked yogurt in the pan and bring the soup to a boil. Fry for 5 minutes. Instead, we rely on tamarind, kokum, kadampulli and tomatoes in our recipes. Remove browned chicken and keep aside.Cut into 1 inch pieces.Add chicken meat.

When the oil is hot and starts smoking, simmer the heat.
Put spices in the center.Meanwhile, the Anglo Indian community has its favourite soup that is still popular at restaurants — the ubiquitous Mulligatawny soup. Discard spice potli.Not surprisingly, our soups are full of nutrients and essential vitamins, thanks to the ingredients employed. "Mulligatawny is an English soup derived from an Indian sauce recipe and is most often served with rice. Squeeze the bouquet garni in the pan and discard it.Drizzle some lemon juice and garnish with coriander leaves. Also break the bones into 2 inch long pieces. Yet surprisingly, Indian soups have held their own from region to region in spite of traditional heavyweights nudging them off the culinary charts in terms of popularity and exposure. Add it in the pressure pan. Strain and remove bones.Remove the pan from heat and let the pressure release. Once the oil is heated, add the chopped onions and sauté them till they are golden-brown in colour.Tamatar and Tulsi Shorba Ingredients:Tamatar- 500gmLime juice: 1 tspVegetable oil: 2 tbspTulsi: 10-12 pcsChilli powder: 1 tspOnion: 1Water: 10 cupsCurry powder: 5 tspCloves: 6Ginger garlic paste: 2 tbspSalt to tasteMethod:Wash and chop the tulsi leaves over a chopping board.Fry bones for 10 minutes.

Now add ginger, garlic, chilli powder and curry powder. In South Asia, it’s a traditional practice to boil spices and make a concoction called ‘kadha’ that is best served as a warm drink before meals.Take rasam, a favourite China meat cutter for sale for colds and coughs. Shorba is derived from an Arabic term, ‘Shurbah’ meaning soup. Bring water to a boil.Most regions have recipes for soups that are fairly unique and distinct from each other based on topography and local ingredients. For a fruity punch, pineapples or plums can be incorporated.Squeeze the head of garlic and add the pulp in the pan. Garnish with coriander leaves, serve piping hot. Add the mutton pieces again and cook for 4-5 minutes.East vs WestUnlike the West, we don’t use butter, cream or bechamel in our soups. Also add the chopped tulsi and salt to the pan..Add browned chicken.
Turn off heat.Garnish with fresh coriander and serve piping hot.Add water, chicken bones, almond paste and spice potli in a pot. However, while soup is often served as the first course, Shorba can also be served as an accompaniment to the main dish or in between courses.Sprinkle Bengal gram powder.

Scientists have developed a magnetised
Researchers at the University of Illinois at Chicago (UIC) in the US found that by adding magnetic particles to surgical cement used to heal spinal fractures, they could guide magnetic nanoparticles directly to lesions near the fractures.. This is a very promising technology as it has the potential to become a surgical option for patients with primary China soybean milk maker for sale spinal column tumours or tumours that metastasise to the spinal column," said Steven Denyer, co-lead author of the study published in the journal PLOS ONE."Our study provides an in vivo proof-of-concept that this novel drug delivery system can help treat underlying causes of spinal fractures in addition to providing structural support," said Abhiraj Bhimani, a student at UIC.
Most commonly, this is achieved by binding a minute amount of drug to the nanoparticle, which is designed to also bind to a specific type of cell, such as a cancer cell.Using a pig model to study the magnetically-guided drug delivery system, scientists were successfully able to steer magnetic nanoparticles to the magnetic cement in the animals spinal vertebrae.While kyphoplasty can stabilise the bone, cancer patients are still often left with spinal column tumours that are very hard to reach with conventional chemotherapy, which has to cross the blood-brain barrier when delivered intravenously.
Scientists have developed a magnetised surgical cement that can be used to heal spinal fractures, and deliver drugs to hard-to-reach areas.Patients with spinal fractures caused by tumours or osteoporosis usually undergo a procedure called kyphoplasty, where the fracture is filled with surgical cement.In future studies to test the efficacy of this technique on treating spinal column tumours, the magnetic nanoparticles would be bound to tiny amounts of chemotherapy drugs."By modifying the kyphoplasty bone cement, we can both stabilise the spinal column and provide a targeted drug delivery system.Nanoparticles bound to various drugs have been used to target drugs to specific locations or types of cells in the body.

It would have been very formal
Akbar has been branded a foreigner defeated in battle and efforts are on to erase Aurangzebs name – if not from history, at least from road signs."Khilji was aware he was cruel but he was not the kind to be running after women and then conquering kingdoms. He was only interested in expansions and conquests," she said. The poet did not project him as a barbarian ruler either.The film, according to Bhansali, is based on the 16th century-epic poem Padmavat written by Sufi poet Malik Muhammad Jayasi two centuries after Khilji’s death.History doesn’t quite remember Alauddin Khilji like this, but that is the image Sanjay Leela Bhansali seeks to portray of the Khilji dynasty king in his film Padmaavat.The poet Amir Khusro, who flourished during the Khilji rule, gave a detailed account of the king’s conquests as well as his reign in the 13th century."There is a clear pattern to colour Islamic rulers as villains with no reference to any facts based on authentic sources of information," said Heeram Chaturvedi, head of department of history at Allahabad University."
The rulers followed the exact potato cutting machine factory code of conduct and etiquette as in Persia.A section of academics believes the depiction of Khilji is only the latest move in a larger movement in parts of the country to distort history.Bhansali’s Khilji, played by Ranveer Singh, has kohl- rimmed hungry eyes, a scarred face, a gym-toned body, wears furs when he is not bare-chested and rips meat off the bone with his teeth.Alauddin was a "cruel imperialist" and a good military strategist who wanted to crush Mongol invaders, she held..New Delhi: He gnaws the meat off the bone, bares his hairy chest, has long unruly locks and laughs like a hyena.
It would have been very formal – the eating, dining and sartorial choices," Safvi said.While members of some Rajput groups are still violently opposing the film’s release, a section of historians states that the filmmaker misses the mark, not in portraying Padmavati, a role played by Deepika Padukone, but in painting the Sultan as a barbarian. Jayasi wrote it in Awadhi, not any Rajasthani dialect.Safvi added that the barbarism the film depicts in Khilji is to only show him as a villain andShahid Kapoors Ratan Singh as a sophisticated rival. It was under his rule the Delhi Sultanate heavily drew from Persia, one of the oldest and most sophisticated civilisations of all time, she said.The king is depicted almost like a barbarian in the film, which was released today after months of strife – in court, on the streets and at the Censor Board."
It cannot be ignored that the epic Padmavat was penned centuries after Khiljis attack. He belonged to a different region," pointed out Arunima Gopinath, associate professor of Womens Studies at Jawaharlal Nehru University.Historian Rana Safvi believes that Khilji was anything but savage.
