Colorectal cancer



Introduction
·         Second most common cause of cancer deaths in the UK.
·         Each year 30,000 new cases diagnosed (68% colon, 32% rectal)
·         Disease more common in westernises countries then Asia or Africa




Aetiology
·         Age (56% >70yrs old)
·         Colorectal polyps
·         Family history
Genetic
o        Hereditary non-polyposis colorectal cancer (HNPCC): autosomal dominant disorder due to mutations in the MMR genes. Associated malignancies found in endometrium and ovaries. Precursor lesion is single colonic adenoma rather then multiple as found in FAP.
o        Familial adenomatous polyposis (FAP): Autosomal dominant mutation in the APC gene leads to hundreds/thousands of colorectal adenomas. Average age of developing colorectal cancer is 39yo. Affected people can have prophylactic colectomies.
·         Previous colorectal cancer
·         Ulcerative colitis /colonic crohn’s disease
·         Diet – hit fat/low fibre
·         Smoking
·         Alcohol drinking
·         Lack of exercise

Pathology/Pathogenesis
·         “Adenoma-carcinoma sequence” majority of adenocarcinomas start as benign adenomas that grow and acquire genetic changes that lead to the development of uncontrolled growth leading to adenocarcinomas.
·         Synchronous tumours found in 2% of cases
·         Most of the tumours found on the left side of the colon
·         Spread is through local invasion through the bowl wall and via local lymphatics, blood (portal vein into liver) and transcoelomic.
·         Histology shows well differentiated glandular epithelium with mucin production. Signet rings common characteristics

Symptoms
Left sided tumour:
  • Tenesmus
  • Blood in stool (fresh red blood)
Obstructive symptoms:
  • Change in bowl habit
  • Colicky abdominal pain
  • Nausea vomiting

Right sided tumour:
  • Weight loss
  • Anaemia
  • Abdominal mass (late stage)

Investigations
·         Rectal examination
Bloods tests:
- FBC (can show anaemia)
- CEA (carcino embryonic antigen – tumour marker normally used to monitor treatment)
- LFTs (show liver secondaries)
- faecal occult blood
·         proctoscopy
·         Barium enema
·         Sigmoidoscopy – tumours in the last 15cm of GI tract
·         Colonoscopy – can take biopsy’s
·         Ultrasound/CT – used to stage look for metastasis (liver)
·         CT colonography – less invasive then colonoscopies

Staging
Dukes
Type A – tumour confined to mucosa/sub mucose
Type B – invaded through bowl wall but lymph nodes clear
Type C – regional lymph nodes involved
Type D - Distant metastasis

TNM Staging System (Tumor, Node, Metastisis)
Tumor
T1: Tumor invades submucosa.
T2: Tumor invades muscularis propria.
T3: Tumor invades through the muscularis propria into the subserosa, or into the pericolic or perirectal tissues.
T4: Tumor directly invades other organs or structures, and/or perforates.

Node
N0: No regional lymph node metastasis.
N1: Metastasis in 1 to 3 regional lymph nodes.
N2: Metastasis in 4 or more regional lymph nodes.

Metastasis
M0: No distant metastasis.
M1: Distant metastasis present.

Stage Groupings
Using the TNM criteria colorectal cancers are placed in to 4 stages:

Stage I: T1 N0 M0; T2 N0 M0
Cancer has begun to spread, but is still in the inner lining.
Stage II: T3 N0 M0; T4 N0 M0
Cancer has spread to other organs near the colon or rectum. It has not reached lymph nodes.
Stage III: any T, N1-2, M0
Cancer has spread to lymph nodes, but has not been carried to distant parts of the body
Stage IV: any T, any N, M1
Cancer has been carried through the lymph system to distant parts of the body. This is known as metastasis. The most likely organs to experience metastasis from colorectal cancer are the lungs and liver.

Management
Surgery:
·         Right colon tumours – right hemicolectomy
·         Transverse colon tumours – extended right hemicolectomy
·         Descending colon tumours – left hemicolectomy
·         Sigmoid tumours - Sigmoid colectomy
·         Right rectal tumour – anterior resection (tumour removed colon anastomosed with remaining rectum) if anastomosis in doubt put in temporary stoma (iliostomy/transverse colostomy) mesentery of rectum also removed (mesorectal excision) avoid local recurrence.
·         Low rectal tumour - Abdomioperoneal resection – excise rectum and anus leaving patient with a permanent colostomy

The idea is to remove entire section of bowl supplied by same blood vessel as tumour to ensure clearance of all cancer cells.
Adjuvant chemotherapy increases survival in Dukes B and C.
Neo-adjuvant radiotherapy can be used for rectal tumours, difficult to use with colonic tumours due to the colon not being fixed in a certain position.
Total mesorectal excision gives better prognosis as it ensures the removal of all cancer cells that may have spread radially to the mesorectal tissue

Prognosis
·         Depends upon stage of the cancer
·         Over 95% survival in dukes A tumours that have been resected
·         When cancer has spread to lymph nodes far from the colon or rectum, to the lining of the abdominal cavity, or to other organs, the cancer cannot be cured by surgery alone. Survival time is typically only about 7 months





World's earliest Battery







This Jar like device is the world's earliest record of Battery “The Parthian Battery” invented by the Iranians as early as 250 BC. In a dramatic excavation by the German Archaeologist Wilhelm Konig three intact jars dating back to the Parthian empire were discovered; later reconstructions and testing of this ancient device in western laboratories has revealed that when the jar of the battery was filled with vinegar (or other electrolytes) it was capable of generating between 1.5-2.0 volts; this pill, according to the expert who studies it, was used for electropolating; the pill is also more commonly known as the Baghdad Battery because it was discovered in vicinity of Baghdad city, the Ancient capital of the Iranian Parthian empire; (Bagh-dad itself is a Persian word meaning God-given)
Batteries of Babylon
"In 1938, Dr. Wilhelm Kong, an Austrian archaeologist rummaging through the basement of the museum made a find that was to drastically alter all concepts of ancient science. A 6-inch-high pot of bright yellow clay dating back two millennia contained a cylinder of sheet-copper 5 inches by 1.5 inches. The edge of the copper cylinder was soldered with a 60-40 lead-tin alloy comparable to today's best solder. The bottom of the cylinder was capped with a crimped-in copper disk and sealed with bitumen or asphalt. Another insulating layer of asphalt sealed the top and also held in place an iron rod suspended into the center of the copper cylinder. The rod showed evidence of having been corroded with acid. Schematic of Babylon BatteryWith a background in mechanics, Dr. Konig recognized this configuration was not a chance arrangement, but that the clay pot was nothing less than an ancient electric battery. The ancient battery in the Baghdad Museum as well as those others which were unearthed in Iraq all date from the Parthian Persian occupation between 248 B.C. and A.D. 226. However, Konig found copper vases plated with silver in the Baghdad Museum excavated from Sumerian remains in southern Iraq dating back to at least 2500 B.C. When the vases were lightly tapped a blue patina or film separated from the surfaces, characteristic of silver electroplated to copper. It would appear then that the Persians inherited their batteries from the earliest known civilization in the Middle East."[1]I
"
 

Scientific awareness
More than 60 years after their discovery, the batteries of Baghdad - as there are perhaps a dozen of them - are shrouded in myth.
"The batteries have always attracted interest as curios," says Dr Paul Craddock, a metallurgy expert of the ancient Near East from the British Museum.
"They are a one-off. As far as we know, nobody else has found anything like these. They are odd things; they are one of life's enigmas."
No two accounts of them are the same. Some say the batteries were excavated, others that Konig found them in the basement of the Baghdad Museum when he took over as director. There is no definite figure on how many have been found, and their age is disputed.
Most sources date the batteries to around 200 BC - in the Parthian era, circa 250 BC to AD 225. Skilled warriors, the Parthians were not noted for their scientific achievements.
"Although this collection of objects is usually dated as Parthian, the grounds for this are unclear," says Dr St John Simpson, also from the department of the ancient Near East at the British Museum.
"The pot itself is Sassanian. This discrepancy presumably lies either in a misidentification of the age of the ceramic vessel, or the site at which they were found."
Underlying principles
In the history of the Middle East, the Sassanian period (circa AD 225 - 640) marks the end of the ancient and the beginning of the more scientific medieval era.
Though most archaeologists agree the devices were batteries, there is much conjecture as to how they could have been discovered, and what they were used for.
How could ancient Persian science have grasped the principles of electricity and arrived at this knowledge?
Perhaps they did not. Many inventions are conceived before the underlying principles are properly understood.
The Chinese invented gunpowder long before the principles of combustion were deduced, and the rediscovery of old herbal medicines is now a common occurrence.
You do not always have to understand why something works - just that it does.

A Shocking Claim That Consciousness Lives In Quantum State After Death!

"DEATH is an inevitable consequence of life, but scientists believe they may have found some light at the end of the tunnel.
Life after death has been “confirmed” by experts who say consciousness continues even once a person’s heart has stopped beating.
In a study of more than 2,000 people, British scientists confirmed that thought persists after death, and simultaneously uncovered convincing evidence of an out-of-body experience for a patient declared dead by medics.
Scientists had believed the brain ceased all activity 30 seconds after the heart stopped pumping blood around the body, and that awareness stopped at the same time.
But research from the University of Southampton suggests otherwise.
A new study shows people continue experiencing awareness for up to three minutes after death."

The Psychological Reason You Care More About This Kid Than Millions of Refugees


The bloodied, dust-covered image of Omran Daqneesh, a 5-year-old Syrian boy from Aleppo whose family home was destroyed in an air strike, is making headlines and heartache in ways that the five-year-old conflict rarely does. The last time this happened was about a year ago, with the photo Aylan Kurdi, a 3-year-old Syrian boy whose drowned body washed ashore on the Greek island of Kos. The outpouring that comes following photos such as these would infuriate a utilitarian philosopher — be it Peter Singer or Jeremy Bentham — since why should people be more motivated to care about the tragedy of a single child rather than the 21 million refugees worldwide who have been forced to flee their homes?
According to a new study in Frontiers in Psychology, it’s because people are more biased toward the plight of one person rather than that of a group. The study, lead-authored by psychologist Daffie Konis at Tel Aviv University, follows up previous research indicating that a single victim leads to greater emotional investment and willingness to give to charity than if there are multiple people suffering. Not only that, people are more satisfied with life-saving interventions if fewer people are at risk.
Konis and her team did three experiments to tease out the “one is more valuable than many” reactions. In one experiment with 127 participants recruited online, subjects read a hypothetical story about Dr. Stillman, a dentist who loved to fish. In the story, the doctor decided to take a long-weekend fishing trip and push back the appointments with patients who were waiting to see him. Every participant read three versions of the story: one with two patients, another with three, and a third with ten. The participants then rated how much they thought patients should be compensated for the misdeed. A majority of participants thought that the fewer the patients, the more they should be compensated and the more the dentist should be punished. In a related experiment, 91 subjects read about the story of a financial adviser named Jeff, who read analyst reports saying the stock market was about to drop, but instead of selling off shares, he left the office to hang out with a friend — leading to a 15 percent drop in clients’ portfolios. Instead of each participant reading every story, this time one group read the story with one client losing money, a second with five unrelated clients, and a third with a five clients with a joint plan. Similar to the first experiment, participants thought that the one client got more screwed over than the group of clients. Again, the paradox held: Jeff was more guilty when just one person got the bad end of his negligence.
In another, more wickedly designed experiment, 81 undergrads took what they thought was a test of their cognitive ability, after which they received false feedback: some that they did better than their peers, some that they did worse. Then they received a disclaimer about their being deceived: some were told that everybody who took the test got tricked in the same way, others were told only they were duped. Again, participants thought the offense was less immoral and harmful when others were involved. To he authors, the findings suggest a moral judgment bias where “a transgression affecting several individuals was paradoxically judged as less (rather than more) severe and immoral than one affecting a single victim.” This helps to understand why Daqneesh is so affecting: he’s just one victim. Regardless of how moral it is, people are apparently biased to caring more about the sorrow of a single figure than a group. If you do feel stirred to donate, effective altruism is a good place to start.

Brain Entanglement


The best I can tell, the "egoic mind" is a software program within the bio-computer brain. We aren't born with it but it develops as part of the brain cells' DNA blueprint. What's interesting is that we have a capacity to simply perceive or observe the software commands as its thoughts, concepts and projections, without following or acting out its directives. It's goal of course is the survival of the organism and ensuring its reproduction.
However our consciousness is of a spiritual nature as embodied through the five main chakras as the interface with the central nervous system. It is not dependent on the brain for its existence, but the quantum wave fields of the brain cause a powerful entanglement matrix with the consciousness especially via the crown chakra and ajna chakra; the seat of consciousness in the area of the pineal gland. The consciousness senses that it is inseparable from the body as a result. We call this the "I am my body" identity illusion.
It seems that if the crown chakra can emanate an electro-magnetic gamma wave field frequency over 40 hz. it can disentangle itself from the brain's software program's wave frequencies.
The closer to 80 hz. gamma wave frequency, the greater the success and likelihood of various ESP phenomena beginning to appear. I would suggest that the "Mind of Clear Light" is a non-brain phenomena that occurs well above 40 hz. gamma wave frequency.
Ordinary thinking and conceptualizing are both the brain's software processing of new perceptual data against a background of information stored in memory. The "Mind of Clear Light" has no thoughts or concepts and is completely non-conceptual and absent of any sense of personal identity as a self.
Initial practice in Dzogchen is the differentiating between the "Mind of Clear Light" and the interference patterns from the brain's software programs, called thoughts. When people have an "out of body" experience they momentarily recover their true, non-physical identity.
The greater the identity with the body the more one's existence becomes one of being an animal. It's obvious on this planet at least that most people are acting out of their animal brain software. And remember that the human animal has 96% the same chromosomes as chimpanzees, so we shouldn't be so shocked by how we see humans treating each other in the daily news reports.

Who were these mysterious beings? Did they evolve separately on Earth?What caused them to have such drastic differences from ordinary humans?

The desert peninsula of Paracas is located on the southern coast of one of South America’s most enigmatic countries: Peru. It is there, in this barren landscape where Peruvian archaeologist Julio Tello made one of the most mysterious discoveries in 1928. During excavations, Tello uncovered a complex and sophisticated graveyard under the harsh soil of the Paracas desert.
In the enigmatic tombs, Tello discovered a set of controversial human remains that would forever change how we look at our ancestor and our origins. The bodies in the tombs had some of the largest elongated skulls ever discovered on the planet, called the Paracas skulls. The Peruvian archaeologist discovered over 300 mysterious skulls which are believed to be at least around 3000 years old.
As if the shape of the skulls was not mysterious enough, a recent DNA analysis performed on some of the skulls presented some of the most enigmatic and incredible results that challenge everything we know about the origin and human evolutionary tree.
Skull Deformation: An ancient religious practice

While several cultures around the globe practices skull deformation (elongation), the techniques used were different, meaning the results were also not the same. There are certain South American tribes that used to ‘bind infants skulls’ in order to change their shape, resulting into a drastically elongated cranial shape that resembled anything but ordinary humans. By applying constant pressure over a long period of time with the use of pieces of mood, the ancient tribes would achieve a cranial deformation which can also be found in ancient cultures from Africa. However, while this type of cranial deformation changed the shape of the skull, it did not alter the size, weight or cranial volume, all of which are characteristic traits of regular human skulls.
This is where the details about the Paracas skulls gets interesting. The Paracas skulls are anything but ordinary. The cranium of the Paracas skulls is are least 25 % larger and up to 60% heavier than the skulls of regular human beings. Researchers firmly believe that these traits could not have been achieved through head bindings as some scientists suggest. Not only are they different in weight, the Paracas skulls are also structurally different and only have one parietal plate while ordinary humans have two.
These strange characteristics have further deepened the decade-old mystery surrounding the Paracas skulls and researchers still have no idea what they were in the past.
Further Testing
The director of the Paracas Museum of History sent five samples of the Paracas skulls to undergo genetic testing, and the results were mesmerizing. The samples which consisted of hair, skin teeth and some fragments of cranial bones gave incredible details that have fueled the mystery surrounding these anomalous skulls. The genetic laboratory to where the samples were sent was not informed of the origin of the skulls in order to avoid ‘influenced results’.
Interestingly, the mitochondrial DNA, which is inherited from the mother, showed mutations that were unknown to any man, primate or animal found on planet Earth. The mutations present in the samples of the Paracas skulls suggest that researchers were dealing with a completely new ‘human-like being’, very different from Homo sapiens, Neanderthals or Denisovans.
Brien Foerster reported the following on the geneticist’s findings:
It had mtDNA (mitochondrial DNA) with mutations unknown in any human, primate, or animal known so far. But a few fragments I was able to sequence from this sample indicate that if these mutations will hold we are dealing with a new human-like creature, very distant from Homo sapiens, Neanderthals, and Denisovans.
According to reports, the individuals from the Paracas skulls were so biologically different that it would have been impossible from humans and them to ‘interbreed’. “I am not sure it will even fit into the known evolutionary tree,” the geneticist wrote.
Who were these mysterious beings? Did they evolve separately on Earth? What caused them to have such drastic differences from ordinary humans? And is it possible that these beings are actually not from Earth? All of these possibilities are theories that cannot be overruled given the current testing. The only thing that we know so far is that there are many things out there that go far beyond the understanding of researchers, historians, and scientists. It is possible that after all, the question to whether we are alone in the universe can be answered thanks to the Paracas skulls.

The Solvay Conference




Cecile G. Tamura
Is this the greatest meeting of minds ever? Einstein and Curie among SEVENTEEN nobel prize winners at historic conference
It would be hard to imagine a more intelligent and brilliant group of people, let alone all these great minds in the same room together.
However this was the case in 1927 when Einstein and his venerable colleagues gathered at the Solvay Conference on Electrons and Photons in Brussels.
The International Solvay Institutes for Physics and Chemistry was founded by the Belgian industrialist Ernest Solvay in 1912, following the historic invitation-only 1911 Conseil Solvay, the first world physics conference.
Since then some of the greatest scientists in the world have come together about every three years to discuss the most perplexing problems in both physics and chemistry.
The most famous conference was the October 1927 Fifth Solvay International Conference on Electrons and Photons, where the world’s most notable physicists met to discuss the newly formulated quantum theory.
The leading figures were Albert Einstein and Niels Bohr. Einstein, disenchanted with Heisenberg’s 'Uncertainty Principle,' remarked 'God does not play dice.' Bohr, who won his Nobel prize in 1922. replied, 'Einstein, stop telling God what to do.'
This was not the only squabble between Einstein and Bohr however, as the two interpretations of the laws of physics was a great source of controversy between the pair. More recent research published in the academic journal, Physical Review Letters, has shown Bohr's theory to be the stronger of the two.
Despite Bohr's obvious talent and immense intelligence, Einstein is still a lot more well known. 'You don't need to be Einstein to work that out' is a common saying still used, whereas Bohr is not nearly as much of a household name.
Einstein received his Nobel Prize in 1922 also, 'for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect'. However the Nobel Committee for Physics decided that none of the year’s nominations met the criteria as outlined in the will of Alfred Nobel.
According to the Nobel Foundation's statutes, the Nobel Prize can in such a case be reserved until the following year, and this statute was then applied.
Seventeen of the twenty-nine attendees were or became Nobel Prize winners, including Marie Curie, who is not hard to spot as the only woman in the photograph.
The charity Marie Curie Cancer is one of the biggest cancer charities in the country, which began in 1948 when committee members decided to preserve the Marie Curie name in the charitable medical field.
Marie Curie had won Nobel Prizes in two separate scientific disciplines.
Also among the distinguished panel was Erwin Schrodinger. Eight years after this group photograph was taken he devised his famous quantum theory called Schrodinger’s Cat.
This suggested something could exist in two different states at the same time until it was observed.
In the experiment, Schrodinger proposed the idea of a cat left in a box with a radioactive substance, which had a 50 per cent chance of decaying and releasing a poison, thus killing the cat within an hour.
Because there is also a 50 per cent chance the substance would not decay, and thus not release the poison, quantum mechanics dictate that the cat is neither alive, nor dead, until the box is opened for measurement.

How (antique) wallpaper was made...

 
The prime desire is to select a wallpaper that shall be in harmony with the main purpose for which the room itself is destined. You would not, for instance, think of mounting the same style of wallpaper on dining, living and bedroom walls alike. Let us take a typical early 1900 house, the original residence of a family belonging to the upper middle class. What rooms will it contain and how shall they be papered? 








There will be an entrance hall, of course, dining room, living room, and morning room, master bedroom and two or three other bedrooms, a nursery probably, besides the kitchen and a bathroom. All will require papering, or re-papering at one time or another.
For the main rooms of the 1900 house, there are various alternative decorative methods available. Paint is one; marble-and-varnish another; a plain self-colored wallpaper is a third; whilst a patterned wall covering makes a fourth. All have their good points to recommend them, and each may possess the defects of its good qualities. You can use a virtual room painter to see what looks best beforehan
First we will consider paint. It may be said that if the hall be not a large one, and therefore, not of prime importance in the internal decorative scheme, paint, of some light but pretty tint (pale pink, cream or mustard yellow) will look well, and form a pleasant background to any flower vases, pictures, etc., that may be placed here. But you have always to remember that paint is but a single tint at best, and can suggest nothing at all to its surroundings. So, unless there are many brightly colored rugs to strew about and colorful flowers readily obtainable, plain paint is difficult to recommend.
Next we will consider marble-and-varnish. During the Victorian 1870s, or thereabouts, the marble-and-varnish effect was the one seen in the hall and passages of seven houses out of any ten, and nobody at that time seemed to think anything else was either possible or necessary. It had a neat, if cold, appearance, and that is about all that could be said for it, whilst it certainly made a smallish entrance look smaller still. This style of mural decoration can safely be dismissed from further consideration.
Next to come under discussion is the self-colored wallpaper, and to a certain extent the remarks made in regard to paint apply to this medium also. A wallpaper will always look a shade or two warmer than paint of the same tint, but otherwise there is not much difference between them beyond this -- that paint soils much the more easily of the two. So we may leave the self-toned wallpapers out of count as well.
There remains a "patterned"  or printed wallpaper to consider. Now we will postulate in the first place that there are few or no pictures on the walls here, while there is a fairly large surface to be covered. Obviously what is needed is a printed wallpaper having a somewhat bold design in the brightest colors. The hall should, in our opinion, always be a part of the house that can be "sat in" on occasion and it should look comfortable consequently. Bright colors on the wallpaper are quite admissible, therefore, especially if the light be not too good. A handsome frieze looks well, too, though one would avoid a dado. But color, anyhow, and if possible something original in the way of a design, since first impressions count for much with visitors. One of the charming William Morris designs or Walter Crane wallpapers would give an admirable appearance here.
The beautiful "panel" wallpapers of the period are worth a special mention. A set of designs showing peacocks among flower blooms is an example of magnificent color scheme and treatment. Another example used during this time showed storks sailing down a white-grounded paper to alight upon the flowers beneath. Any house owner would have delighted to paper their hall with either.
Quite a different decorative effect is wanted for the dining room walls. Here you have a room set apart for a definite and distinctive purpose -- that of replenishing the inner man. No marked extraneous influence should be present to deflect him from that purpose. So the dining room wallpaper, while warm and cheerful, should contain nothing startling, nothing on the "showy" side, in either in color or design. A pleasant Indian theme relieved by an artistic wainscoting or dado looks as well as anything, especially if there be a few good pictures on the walls. If the room be a large one, a dullish pattern of scroll work in low coloring will look well. But in any case, there should be no outstanding feature in the design to distract attention from the serious business of eating that is the room’s purpose. Naturally, if the home has low walls, no dado will be needed, as this would make them appear lower still. The paintwork about this room should be in clear contrast to the paper.
Next in importance is the drawing or living room. Here the decorator may let himself go to any extent, provided cost is not a particular object to the client. Just as a subdued plain wallpaper is the thing required for the dining room, so for the living room a light, gracefully patterned and tinted wallpaper is the first choice. There are very many well-known and charming styles of living room wall coverings, many of them French in character. The "Empire" is one of the most pleasing, perennially popular alike for the grace of its outlines and the delicacy of its coloring. The pattern is too large, however, for any but a big room.
In a drawing room or living room of small dimensions a "Chintz" printed wallpaper will look extremely pretty, particularly so if the chair and ottoman coverings are of a pretty bright chintz pattern likewise. Pains will of course be taken to see that wallpaper and furniture coverings "tone" one with the other. Again, the invariable artistic rule must be studiously observed of mounting a wallpaper with a smallish pattern in a low-ceilinged room, or if "stripes" are employed these must be vertical and not horizontal. Paneled papers, of whatever kind, are only for very magnificently sized rooms.
