Vitamin D for Cancer Prevention.

  • Higher serum levels of the main circulating form of vitamin D, 25-hydroxyvitamin D (25(OH)D), are associated with substantially lower incidence rates of colon, breast, ovarian, renal, pancreatic, aggressive prostate and other cancers.
  • new model of cancer etiology that accounts for these actions of 25(OH)D and calcium.
  • Its seven phases are disjunction, initiation, natural selection, overgrowth, metastasis, involution, and transition (abbreviated DINOMIT).
  • Vitamin D metabolites prevent disjunction of cells(Upregulates E-Cadherins,Catenins and intercellular junctions) and are beneficial in other phases.
  • It is projected that raising the minimum year- round serum 25(OH)D level to 40 to 60 ng/mL (100–150 nmol/L) would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year
  • Such intakes also are expected to reduce case-fatality rates of patients who have breast, colorectal, or prostate cancer by half.
  • There are no unreasonable risks from intake of 2000 IU per day of vitamin D3, or from a population serum 25(OH)D level of 40 to 60 ng/mL.

Oxygen therapy relieves headache pain in the ED, cuts length of stay, drug use.

Giving high-flow oxygen therapy for 15 minutes to emergency department patients with headaches provides rapid relief and reduces hospital stays, use of CT scans, and headache pharmacotherapy, according to a pilot study.

Dr. Boris Veysman of the University of Medicine and Dentistry of New Jersey-Robert Wood Johnson Medical School reported the results on Monday at the annual meeting of the American College of Emergency Physicians in Boston.

"Very often, when a patient comes to the emergency department with one complaint being headache, they're uncomfortable and symptomatic and they have to wait for a workup before anyone can determine the cause. A diagnosis may not even be made in the emergency department," Dr. Veysman told Reuters Health. "So we approached it from a different perspective and asked, 'What if therapy were the first thing you did (for a headache) before attempting to find a cause?' And so we tried giving oxygen therapy, because it's so widespread and safe."

In the placebo-controlled study, 17 patients were randomized to 100% oxygen at 15 L/min for 15 minutes; 14 received high flow air for 15 minutes; and 17 received no intervention prior to standard treatment. Headache intensity was assessed using a 10-point visual analog scale.

Median times to relief were significantly shorter for patients treated with oxygen (40 minutes) compared with those treated with high flow air (110 minutes) or nothing (120 minutes). Median length of stay was also significantly shorter for patients treated with oxygen (57.5 minutes) than for those treated with air (210 minutes) or nothing (180 minutes).

In addition, CT scans were ordered less frequently: for four of 17 patients (24%) who received oxygen; 11 of 14 (79%) who received air; and eight of 17 (47%) who got nothing.

Medication was given to 29% of those who received oxygen, 86% of those who received air, and 82% of those who received no treatment.

Headache intensity was significantly reduced at both 15 minutes and 30 minutes after initiation of treatment, with patients treated with oxygen realizing the greatest reductions.

The conclusion is what interested me(Lines in the screenshot)

October 8-World Sight Day 2009 "Gender and Eye Health – equal access to care" #WSD09

VISION 2020 - World Sight Day 2009

  • World Sight Day 2009
  • The theme of World Sight Day 2009 (WSD09) is: Gender and Eye Health – equal access to care
  • Global Key Messages for WSD09 Nearly two-thirds of blind people worldwide are women & girls In many places, men have twice the access to eye care as women Equal access to eye care could substantially reduce blindness in poor countries* Simple and effective strategies can and do successfully address this inequity within VISION 2020: The Right to Sight
  • Don't forget: 80% of blindness is avoidable - either treatable, curable or preventable 90% of blind people live in low-income countries Cataract is the leading cause of blindness – yet it is curable by a simple, cost-effective operation 8 million people worldwide are blind due to uncorrected refractive errors. A simple sight test and glasses could restore sight to most of these people
  • Up to 80% of the world's blindess is avoidable.

    Avoidable blindness is defined as blindness which could be either treated or prevented by known, cost-effective means. Although there are many other causes of vision impairment, VISION 2020 seeks to address the main causes of avoidable blindness, in order to have the greatest possible impact on vision loss worldwide.

    The target disease areas for VISION 2020 are:




    Childhood Blindness

    Refractive Error

    Low Vision


    Diabetic Retinopathy

    Age Related Macular Degeneration

2009 Nobel Prize in Chemistry to Venkatraman Ramakrishnan, Thomas A. Steitz and Ada E. Yonath

  • 2009 Nobel Prize in Chemistry to Venkatraman Ramakrishnan, Thomas A. Steitz and Ada E. Yonath
  • The Royal Swedish Academy of Sciences has decided to award the 2009 Nobel Prize in Chemistry jointly to Venkatraman Ramakrishnan, MRC Laboratory of Molecular Biology, Cambridge,United Kingdom Thomas A. Steitz, Yale University, New Haven, CT, USA Ada E. Yonath, Weizmann Institute of Science, Rehovot, Israel
  • "for studies of the structure and function of the ribosome"
  • The knowledge about the ribosome's inner workings is put to practical use in many of today's antibiotics which cure diseases by blocking the function of bacterial ribosomes. Bacteria cannot survive without functional ribosomes, so ribosomes are an important target for new antibiotics.
  • They used a method called X-ray crystallography to map the position for each and every one of the hundreds of thousands of atoms that make up the ribosome.  They have generated 3D models that show how different antibiotics bind to the ribosome. These models are now used to develop new antibiotics, directly assisting the saving of lives and decreasing humanity's suffering.

This is a screenshot of the official Nobel website.I am disappointed that they have not cared to acquire and post the image of Sir Venkataraman.

WHO pain relief ladder in cancer palliation therapy

  • WHO has developed a three-step "ladder" for cancer pain relief.
  • If pain occurs, there should be prompt oral administration of drugs in the following order
  • nonopioids (aspirin and paracetamol)
  • then, as necessary, mild opioids (codeine)
  • then strong opioids such as morphine, until the patient is free of pain.
  • To calm fears and anxiety, additional drugs – “adjuvants” – should be used.
  • To maintain freedom from pain, drugs should be given “by the clock”, that is every 3-6 hours, rather than “on demand”
  • This three-step approach of administering the right drug in the right dose at the right time is inexpensive and 80-90% effective.
  • Surgical intervention on appropriate nerves may provide further pain relief if drugs are not wholly effective.

American trio get nobel prize for medicine(2009)for discovering 'Telomerase'.

  • Three Americans Share Nobel Prize for Medicine
  • Americans Elizabeth H. Blackburn, Carol W. Greider and Jack W. Szostak won the 2009 Nobel Prize in medicine on Monday for discovering a key mechanism in the genetic operations of cells, an insight that has inspired new lines of research into cancer.
  • The first time two women have been among the winners of the medicine prize
  • The trio solved the mystery of how chromosomes, the rod-like structures that carry DNA, protect themselves from degrading when cells divide.
  • Telomeres that are often compared to the plastic tips at the end of shoe laces that keep those laces from unraveling.(What a beautiful analogy!)
  • Blackburn and Greider discovered the enzyme that builds telomeres -- telomerase -- and the mechanism by which it adds DNA to the tips of chromosomes to replace genetic material that has eroded away.
  • Some inherited diseases are now known to be caused by telomerase defects, including certain forms of congenital aplastic anemia, in which insufficient cell divisions in the stem cells of the bone marrow lead to severe anemia. Certain inherited diseases of the skin and the lungs are also caused by telomerase defects.

Emailing, texting may harm you- Really!I will email this right away to all my frens:)

Experts have warned that the increasing popularity of social networking sites, emailing and texting may be injurious to public

Nada Kakabadse, a professor at Northampton University, says that these technologies are leading to anxiety, reduced productivity and a generation of smartphone orphans.

She points out that people these days are increasingly becoming obsessed with information from an ever growing number of sources. "One third of our sample suffer from technological addiction. They are addicted to their gadgets - phones, BlackBerries, laptops. It is a problem. It has negative consequences on their family life, their health and their social life," Sky News quoted her as saying.

Nada says that “pop-up alerts” often interrupt netizens from their primary task in favour of reading emails, and then direct them to other online links. She says that people then suddenly feel low energy, become clumsy and have a spatial disorder.

The expert says that even though people become exhausted, they may check other stacked up behind the new one, have a quick look on Facebook, Twitter or something else, and it may be half an hour before we’’re back to that primary task. "You can not any more do effectively the task you were originally doing, even if it was routine. You will suddenly feel low energy, you become clumsy and you have a spatial disorder. You become exhausted," Nada said.

In a survey of 4,000 email users that the US firm AOL recently conducted in America, 46 per cent described themselves as being "hooked" on email. Nearly 60 per cent had checked email in the bathroom, 15 per cent checked it in church, and 11 per cent had hidden the fact that they were checking it from those around them.

And this is said to have given rise to the phenomenon of BlackBerry orphans, children who desperately fight to regain their parents’’ attention from the devices. Susan Bailey, a principal lecturer at Northampton University, says that she need look no further for a techno-addict than herself. "I probably only sleep four hours a night. And immediately when I wake up I feel that I have to connect. My family would say it is a problem. I am trying to manage it," she said.

The answer, according to digital strategist Andrew Grill, is techno-management.

"I think it wouldn’t hurt to have people to help us understand how to relax with all this digital information," he said. "I read an interesting tweet the other day about someone who learnt how to turn off the flashing light on their BlackBerry and it had apparently changed their life.

They are now regulating their usage because they don’t feel the need to pick it up every time it flashes," he added.

He says that it is about simple management and a little self control.
