Eight Nigerian Children with Heart Disease undergo open heart surgery in India

Nigerian children heart surgery in India

Eight children from Nigeria suffering from congenital heart  disease were operated successfully through open heart surgery in India by peadiatric cardiac specialists at Innova Hospitals at Hyderabad in India, in early December 2012. Team Innova comprising of Dr. K. S. Murthy, Prof. I. M. Rao, Dr. K. V. Ramana, Dr. Gnanasekhar, Dr. Rama Krishna, Dr. Pankaj Kumar and Dr. Yogesh operated on the Nigerian kids. These surgeries were sponsored by MTN-Nigeria under a CSR initiative. The children hail from deprived families, one of them being an orphan. These children aged between 1 – 10 years were suffering from complex birth defects in the heart. Three of them were sick on arrival and were admitted in the ICU. One of the 3...

Cancer cell has potential on-off switch

Lung cancer treatment in India

Epigenetics is the phenomena in which genetically identical cells succeed in expressing their genes differently and it result in different physical traits. At present, it is believed that cancer develops from environmental and genetic changes to cancer progenitor cells. These changes occur due to mutations, exposure to toxic substances or hormonal imbalances. "If we believe that everything in nature occurs in an organised fashion, then it is logical to assume that cancer development cannot be as disorganised as it may seem," said Sibaji Sarkar, instructor of medicine at Boston University School of Medicine (BUSM). "There should be a general mechanism that initiates cancer progression from predisposed progenitor cells, which likely involves epigenetic changes," said Sarkar. Read more: Cancer Treatment by...

Sugar is the culprit behind heart diseases

Researchers have uncovered evidence that sugar has a direct effect on risk factors for heart disease, and is likely to impact on blood pressure, independent of weight gain. Research Fellow with Otago's Department of Human Nutrition Dr Lisa Te Morenga, Professor Jim Mann and colleagues have conducted a review and meta-analysis of all international studies that compared the effects of higher versus lower added sugar consumption on blood pressure and lipids (blood fats or cholesterol) - both of which are important cardiovascular risk-factors. They located dietary intervention trials published in English-speaking journals between 1965 and 2013, comparing diets where the only intended differences were the amount of sugars and non-sugar carbohydrates consumed by the participants, and which measured the effects...

Garlic can fight hardiest bacterial strains

A chemical compound in the humble garlic can neutralise resistant bacteria by paralysing their communication system, scientists say. Bacteria are developing resistance at an alarming pace, and aggressive multi-resistant infections constitute an increasing health problem all over the world, researchers said. Tim Holm Jakobsen, from University of Copenhagen, said that ajoene - the substance present in garlic - specifically prevents the bacteria from secreting the toxin rhamnolipid which destroys white blood cells in the body. White blood cells are indispensable because they play a crucial role in the immune defence system, not only warding off infection, but also killing bacteria, he said. When bacteria clump together in what is known as biofilm - where they surround themselves with a tough...

Scientists Identify the Switch that Says It’s Time to Sleep

The switch in the brain that sends us off to sleep has been identified by researchers at Oxford University’s Centre for Neural Circuits and Behaviour in a study in fruit flies. The switch works by regulating the activity of a handful of sleep-promoting neurons in the brain. The neurons fire when we’re tired and need sleep, and dampen down when we’re fully rested. “When you’re tired, these neurons in the brain shout loud and they send you to sleep,” says Professor Gero Miesenböck of Oxford University, in whose laboratory the new research was performed, in a release. Although the research was carried out in fruit flies, or Drosophila, the scientists say the sleep mechanism is likely to be relevant to...
