Retrograde (reversed) blood flow in healthy astronauts during 50 days space flight. 
JAMA Network
Exposure to a weightless environment during spaceflight results in a chronic headward blood and tissue fluid shift compared with upright posture on Earth. To investigate the association of the change with cerebral venous outflow, researchers obtained jugular vein ultrasonography of healthy crew members participating in long-duration spaceflight missions to the International Space Station. Stagnant and/or reverse internal jugular vein flow was observed in 6 of 11 crew members on flight day 50. This ultrasonography video illustrates an example of retrograde (grade 4) flow; blood in the internal jugular vein is flowing in the reverse direction (toward the head, left). Click

Physiology & Medicine / Recent Flooding: Has it resulted in a parasite epidemic in grazing animals?

« on: 08/11/2014 18:21:43 »

http://youtu.be/EmPzVaqfhQQ

Having fed our dogs raw meat for many years, collected from an abattoir or purchased frozen from other sources, it came to our attention that the last batch of raw green tripe were infected with parasites that at first looked similar to seeds inside a pomegranate.

To add to this, earlier in the year we came across a cow in a heard that had severe oedema in it's jaw line and recent research into this particular parasite has revealed that the cow's condition is bottle-jaw, a symptom related to heavy fluke infections.

The video from the link provided is short and to the point and graphically shows the Rumen fluke along with the infected cow.

Note on reporting the cow, which was in Churston, Torbay, South Devon UK we were told that the cow was allergic to grass and sunlight, which not for a minute did we accept. It was then reported to the local area vet connected to DEFRA and we were assured that they would call back to let us know the outcome and didn't.

The history of this particular parasite has shown a rapid spread throughout the UK and I suspect that given the fact that it requires a water snail host to proliferate, the recent flooding may have accelerated the success of this leach like invader. What do you think?

The Environment / How do you install a grey water DIY System for under £65.00?

« on: 24/06/2010 20:57:54 »

http://www.waterwise.org.uk/reducing_water_wastage_in_the_uk/house_and_garden/clothes_washing_at_home.html
According to Water Wise, we use about 14% per cent of our domestic water supply to wash clothes. A new machine uses around half the water and energy of the average 10-year-old machine. Many of the most efficient washing machines now use less than 50 litres of water per wash.
Washing machine use has risen by 23% in the past 15 years, up from 3 times a week in 1990 to an average of 4 times a week per household today.

If your machine is 10 years or more, it will use 100 litres per wash, Washing 4 times a week will use 400 litres. Many families wash 7 times a week, that’s a whopping 700 litres down the drain.
Installing this DIY grey water system saves the 700 litres of water from the plughole, and enables us to re-use the water for other tasks including watering the garden, cleaning the car, hosing down the patio and flushing the toilet. This means we have liberated the 700 litres from the water rates. We now grow our own food and use the grey water for all the plants in the garden except for salad plants, saving us a lot of extra money by not having to drive to the supermarket to get certain expensive summer food.
The cost to install it yourself is £39.00 for the pump (Ebay) £10.00 for the switch and fittings to connect it (local trade plumbing store) £15.00 for the plastic barrel (ex fruit juice container from Mole Valley Farmers) just under £65.00 completed.

Famous Scientists, Doctors and Inventors / Roger W. Sperry The Nobel Prize in Physiology or Medicine 1981

« on: 26/12/2009 14:42:49 »

Roger W. Sperry
The Nobel Prize in Physiology or Medicine 1981

In experiments with fish, frogs, and salamanders (chosen because they have great powers of regeneration), Sperry demonstrated that individual nerve fibers (which are actually different cells) behave as if each is chemically different from every other, and these chemical differences are matched in the brain. The result is that in an animal whose optic nerves are severed and then allowed to regenerate, the thousands of individual fibers that make up each optic nerve grow back into the brain and there make the same connections they had before. The animal is then able to see as if the nerves had never been severed. Proof that no adaptive reorganization of the neural circuits is involved in regeneration consisted of showing that if an eye whose optic nerve is severed is also rotated in its socket, the world seen by the eye after regeneration is still upside down and backwards. Furthermore, as in the case of the rat with the crossed nerves, no amount of retraining makes it see correctly: the animal invariably strikes to the left when it sees a worm on its right.

The conclusion that the circuitry of the brain is fixed in early development is supported by much more evidence than I can summarize here. It has given rise to a field of research focused on "axonal guidance". Sperry's result concerning the chemical individuality of each nerve fiber has been confirmed by modern molecular methods. It is a result that is loaded with meanings at many levels - from immediate consequences for neurosurgery to large and still not fully explored implications for evolution and development, and even for social-political questions. It raises other fascinating and still unsolved questions. For example, the capacity to learn obviously implies some neural plasticity. But given the basic determinism of the brain that Sperry uncovered, what does learning actually consist of at the cellular and chemical level? These and other questions posed by his findings are now being studied, and no doubt they will continue to be worked on for a long time in the future.

Complementary Medicine / Clinical Trial Results of Hawthorn Extract for High Blood Pressure.

« on: 18/07/2009 11:25:19 »

Going to give this a whirl as bp is up at the moment.


The patients taking hawthorn had a significant reduction in mean DBP over 16 weeks compared with those on placebo (-2.6 vs +0.5 mm Hg, P = .035). There was no difference between the 2 groups with regard to mean SBP reduction, although a nonsignificant (P = .096) decline of 3.6 mm Hg was seen in the hawthorn group, Dr. Walker and her colleagues reported. There was no significant outcome difference between groups in the indices of glycemic control (fasting glucose, glycated hemoglobin, and fructosamine). No herb-drug interactions were found and minor health complaints were reduced from baseline in both groups.

"The blood pressure lowering effect in this study was real, and worked in addition to the drugs being taken by patients," said Dr. Walker. "There has been a great deal of confusing publicity about herbal remedies affecting the efficacy of prescribed drugs, but we were able to confirm there were no side effects or adverse reactions," she said. "As hypertension is such a huge problem in Western societies, any safe, natural approach, which can be used with or without modern drugs, is worth exploring. It is possible to have modern and herbal medicines working in harmony." http://cme.medscape.com/viewarticle/537304_6

Complementary Medicine / Vitamin C for the Big C ? Could High Doses of ascorbate be the cure for cancer?

« on: 14/06/2009 10:45:27 »

Vitamin C 'slows cancer growth'
   
TREATMENT IMPACT
See the impact of vitamin C treatment on mice with tumours.

An injection of a high dose of vitamin C may be able to hold back the advance of cancers, US scientists claim.

The vitamin may start a destructive chain reaction within the cancer cell, they add.

The jab halved the size of brain, ovarian and pancreatic tumours in mice, reported the journal Proceedings of the National Academy of Sciences.

However, Cancer Research UK said other studies suggested large vitamin C doses may interfere with cancer treatment.

   
This is encouraging work but it's at a very early stage because it involves cells grown in the lab and mice
Dr Alison Ross
Cancer Research UK

Earlier research by the team at the National Institutes of Health in Maryland had suggested that the vitamin, also called ascorbate, could kill cancer cells in the laboratory.

After these successful tests in mice, they are now suggesting that the treatment be considered for human use at similar levels.

The dose they employed - up to four grams per kilo of bodyweight - was far greater than any that could be achieved using diet or vitamin pills, as the digestive system does not absorb more than a fixed amount taken orally.

The mice were bred to have malfunctioning immune systems, then injected with human cancer cells, which as a result, grew quickly into large tumours. The vitamin was then injected into their abdominal cavity.

Tumour growth and weight fell by between 41% and 53%, and while in untreated mice, the disease spread rapidly to involve other body parts, no such spread was seen in the vitamin C-treated animals.

The researchers wrote: "These pre-clinical data provide the first firm basis for advancing pharmacologic ascorbate in cancer treatment in humans."

Peroxide bomb

The treatment works because a tumour cell is chemically different to a healthy cell.

The vitamin C reacts with this chemical make-up, producing enough hydrogen peroxide to kill the cell, while leaving healthy cells unscathed.

However, Dr Alison Ross, from Cancer Research UK said that much more work would have to be done to see if vitamin C could be a viable treatment.

"This is encouraging work but it's at a very early stage because it involves cells grown in the lab and mice.

"There is currently no evidence from clinical trials in humans that injecting or consuming vitamin C is an effective way to treat cancer.

"Some research even suggests that high doses of antioxidants can make cancer treatment less effective, reducing the benefits of radiotherapy and chemotherapy."

Vitamin C 'helps to fight cancer'
oranges
High dose vitamin C injected into the bloodstream help fight cancer
High doses of vitamin C injected into the bloodstream may help fight cancer, a US study says.

Scientists found that intravenous vitamin C in the form of ascorbate killed cancer cells in lab tests.

The findings contradict earlier studies, but the Maryland-based Institutes of Health said they had looked at lower-dose oral vitamin C.

Cancer experts said the "overwhelming" evidence still suggested vitamin C was not an effective treatment.

Studies in the 1970s first suggested the administration of high doses of vitamin C could help treat cancer, but later research did not back this up.

   
There are many substances that have been shown to kill cancer cells in the lab but failed to fulfil that promise when tested in people
Henry Scowcroft, of Cancer Research UK

In the latest study, published in the Proceedings of the National Academy of Sciences, researchers conducted laboratory experiments which simulated clinical infusions of vitamin C on a range of nine cancer and four normal cells.

In five of the cancer lines, there was a 50% decrease in cell survival, while normal cells were unaffected.

A more detailed look at lymphoma cells - which were especially sensitive to ascorbate - showed they were killed completely.

The effective dose was around four millimoles, a concentration much higher than an oral dose but easily achievable by intravenous infusion.

Cells

Researchers were unable to explain what caused the results, although they did note the treatment led to the formation of hydrogen peroxide, a chemical known to be toxic to cells.

Alternative medicine practitioners have already administered high doses of intravenous ascorbate.

INTRAVENOUS VITAMIN C and CANCER

by Ron Hunninghake, M.D.

"...it takes much more than logic and clear-cut demonstrations to overcome the inertia and dogma of established thought." — Irving Stone

Irving Stone was an early thinker and writer about vitamin C (its scientific name is ascorbic acid). He knew it would be an uphill battle to change the way the medical profession viewed vitamin C. While most doctors accept that scurvy is a vitamin C deficiency illness, few have made the rather humongous jump to seeing high dose intravenous vitamin C as a major player in the management of cancer.



Lead researcher Dr Mark Levine said the treatment would have to be proved safe before being given to patients.

But he added: "Ascorbate as a potential cancer therapeutic agent has a controversial and emotionally charged past."

Henry Scowcroft, senior information officer at Cancer Research UK, said despite the findings, the "overwhelming" evidence still pointed to vitamin C not being an effective treatment.

"This work is at a very early stage. There are many substances that have been shown to kill cancer cells in the lab, but failed to fulfil that promise when tested in people.

"But we do know that eating a healthy, balanced diet, including plenty of fresh fruit and vegetables, is an effective way to reduce the risk of getting cancer in the first place."

The Environment / Thermal Solar Panel DIY Project for domestic hot water under £100

« on: 21/04/2009 20:33:37 »

Click on Link For Slide Show:

70cmx45cm timber   2 lengths 214 cm  2 lengths 81cm mitred grip fixed and screwed to form the frame to house your solar panel.

2 lengths of 3x5cm to support galvanised corrugated sheet sides

I standard corrugated tin roof sheet  (recycle centre £5.00) overcharged me IMO J

Black foam backed reflective foil faced thermal lagging (lucky find in recycle centre £2.00) This is used on the underside of the corrugated steel sheet to prevent heat escaping from the back of the panel. (pictures to follow)

Perspex cover sheet. A used aluminium window and frame can do the same job. This is to provide a heat retaining shield to let the energy in from the sun and prevent the heat escaping from the mat black painted corrugated sheet an copper tubing carrying the domestic hot water.

2x 3meter lengths of 22 mil copper tube
6x 3 meter lengths of 15 mm copper tube
16 x   22mm reducing Tees to 15 mm middle outlet fittings
4x 22 mm elbows
2 15mm sockets to join offcuts to save on copper tubing requirements.


Make wooden frame mitre the ends, grip fix or wood glue and screw ends together

This should be made so that the corrugated sheet fits inside with ease, the bottom and top edges of the sheet are cut with tin snips and bent to a right angle. Screws can be hammered through the thin sheet to secure the top and bottom.

The 2 lengths of 3x5cm are nailed flush with the edge of the frame on both sides. The corrugated sheet is inserted and secured by hammering screws through the sheet, best done with a screw driver and hammer, then wizzed up with the powered screw driver after you have lagged the back of the sheet with the reflective foam backed lagging. This way the tin sheet secures the lagging and the sheet in one go. Allow sufficient lagging to hang over the sides of the frame so that the Perspex/ glass lid can be secured to form a nice weather proof gasket.

Once the frame is lagged and secured with screws along the sides and the snipped corrugated ends of the sheet are folded over these can be secured again by driving the screws through the thin sheet into the wooden frame with a hammer.

Now for the soldering bits n bobs.

The 22 mm tube is for the outer edge fitting inside the timber frame sides, top and bottom, with an outlet via a Tee converter at the bottom and on the top at the opposite side giving maximum distribution of the inflowing cold water (bottom) and out-flowing hot water (top opposite side)

Each corrugation on the tin sheet will have a 15 mm copper pipe joined at the top and bottom by a reducing Tee fitting. Repeat until all corrugations have a 15 mm pipe. When all the soldering is checked for leaks under pressure by linking to the mains via a jubilee clip and hose pipe or whatever method you choose and you are certain there are no leaks.


Spray paint the sheet surface and pipes with mat black heat resistant stove paint or exhaust paint. This is going to get hot quickly.

The idea is using aerosol paint we can have a very thin mat black surface to maximise heat transfer to the water inside the tubes.

Secure the Perspex / glass lid in place and couple it to either an indirect heating system or a direct heating system making sure there is an expansion tank on the system to take care of increased pressure building up as the water expands when heated and does not compress. I used plastic lugs shown in picture to secure the perspex sheets as they are prone to crack if drilled and screwed

Adequate lagging and an outside isolating stop cock and drain plug for those freezing winter nights might be a worthy consideration.

My system hopefully will run solar heated water back to my combi boiler, which fingers crossed should not have to fire up and if it does fire up will shut off once the heated water reaches the internal thermostat. Though on sunny days, we should have hot water with the boiler turned off.

Early days yet and more modifications may be required, but thought you might be interested in this project designed to supply our hot water needs.

This total build is costing under a hundred pounds!

My philosophy is if I put a hundred pounds in the bank, by the end of the year, given the pathetic interest rates and poor performance of the pound against the euro, I will probably have lost money.

Here my hundred pounds will earn me money every time we have some moderate sunlight.

220 deaths and 2,658 injured in first four dangerous days

BANGKOK: -- Road casualties climbed to 220 deaths and 2,658 people injured as 2,658 accidents were recorded nationwide in the first four of the "seven most dangerous days" of the Songkran festival.

Chiang Rai had the most accidents at 102 followed by Nakhon Si Thammarat at 94, Paichit Varachit, deputy permanent secretary of the Public Health Ministry, said yesterday.

Monday alone saw 863 traffic accidents with 81 deaths and 940 injuries.

Driving under the influence of alcohol was the major cause of accidents followed by speeding.

Most mishaps involved motorcycles driven from 4pm8pm.

Nakhon Si Thammarat had the most accidents on Monday at 36 and the most injuries at 47 cases, while Nakhon Sawan had the most deaths at seven.

In the four days to Monday, emergency medical units went out on 12,621 missions, with 5,149 to minister to people including those suffering from road accidents, 5,513 to treat illnesses, 932 to dress wounds from fighting and 38 to attend to victims of water accidents.

Anucha Mokhaves, directorgeneral of the Disaster Prevention and Mitigation Department, said provincial authorities and police were instructed to warn motorcyclists and passengers to strictly follow traffic rules and regulations, as Songkran travellers were expected to start returning to Bangkok today.

Officials manning checkpoints would also take extra measures in areas prone to accidents, he added.

Physics, Astronomy & Cosmology / Small planet found close to the sun and obscured by asteroid belt.

« on: 01/04/2009 18:46:53 »

http://www.newscientist.com/issue/current

The Planet, discovered by a German physicist Gertrude Schmidt who first tracked the newly forming planet at 14.35 on February the 31st said we are incredibly excited by this find and believe we have much to learn about this developing new planet, thought to be approximately half the size of Mars.

According to Schmidt, it is unlikely to support life and is thought to be cooling down rapidly from it’s creation, estimated to be around 3.5 billion years.

We asked how come it has taken scientists so long to find this planet? Schmidt said; “The planet has been obscured from view until now because it has been orbiting on the inside of an asteroid belt close to the sun.

Cells, Microbes & Viruses / New Ideas About the Cause, Spread of Lyme Disease

« on: 30/03/2009 09:36:32 »

New Ideas About the Cause, Spread
and Therapy of Lyme Disease
by Dr. James Howenstine

Townsend Letter for Doctors and Patients, July 2004

Lyme Disease was initially regarded as an uncommon illness caused by the spirochete Borrelia burgdorferi (Bb).  The disease transmission was thought to be solely by the bite from a tick infected with this spirochete.  The Bb spirochete is able to burrow into tendons, muscle cells, ligaments, and directly into organs.  A classic bulls-eye rash is often visible in the early stage of the illness.  Later in the illness the disease can afflict the heart, nervous system, joints and other organs.  It is now realized that the disease can mimic amyotrophic lateral sclerosis, Parkinson’s disease, multiple sclerosis, Bell’s Palsy, reflex sympathetic dystrophy, neuritis, psychiatric illnesses such as schizophrenia, chronic fatigue, heart failure, angina, irregular heart rhythms, fibromyalgia, dermatitis, autoimmune diseases such as scleroderma and lupus, eye inflammatory reactions, sudden deafness, SIDS, ADD and hyperactivity, chronic pain and many other conditions.

Biology professor, Lida Mattman, author of Cell Wall Deficient Forms: Stealth Pathogens, has been able to recover live spirochetes of Bb from mosquitos, fleas, mites, semen, urine, blood, and spinal fluid.  A factor contributing to making Bb so dangerous is that it can survive and spread without having a cell wall (cell wall-deficient CWD).  Many valuable antibiotics kill bacteria by breaking down the cell wall.  These antibiotics often prove ineffective against Bb.

Lyme Disease is now thought to be the fastest growing infectious disease in the world.  There are believed to be at least 200,000 new cases each year in the US and some experts think that as many as one in every 15 Americans is currently infected (20 million persons).  Dr. Robert Rowen knows a family where the mother’s infection spread to 5 of her 6 children1 all of whom recovered with appropriate therapy.  It is difficult to believe that these children were all bitten by ticks and seems more plausible that person to person spread within the family caused this problem.  Dr. Mattman states “I’m convinced Lyme disease is transmissible from person to person.”  In 1995 Dr. Mattman obtained positive cultures for Bb from 43 of 47 persons with chronic illness.  Only 1 of 23 control patients had a positive Bb culture.  Dr. Mattman has subsequently recovered Bb spirochetes form 8 out of 8 cases of Parkinson’s Disease, 41 cases of multiple sclerosis, 21 cases of amyotrophic lateral sclerosis and all tested cases of Alzheimer’s Disease.  The complete recovery of several patients with terminal amyotrophic lateral sclerosis after appropriate therapy shows the great importance of establishing the diagnosis of Lyme Disease.
