New drug to cure diabetes,can we cure type 2 diabetes,certain diabetes pills can help you lose weight unhealthy - .


It is estimated that around 215,000 people in the UK have chronic hepatitis C, but there may be some good news for those suffering. A new pill treatment that is said to offer a "cure" for the chronic liver disease has been launched in the UK.
The drug daclatasvir can rid 90% or more patients of the infection in 12 weeks when combined with other agents. Used with another pill, sofosbuvir, it has produced clinical cure rates of 89% and 98% in patients with different viral strains. Standard treatment for hepatitis C involves injections of the immune system stimulator interferon and can have serious side effects.
The launch of daclatasvir makes a daily pill-only treatment for the disease available that brings eradication of hepatitis C a step closer. Charles Gore, chief executive of the Hepatitis C Trust, said: "We are delighted by today's announcement. Hepatitis C, a blood-borne virus commonly spread by drug takers sharing needles, can hide for years without producing symptoms before leading to potentially fatal liver damage or cancer.
Trial results showing the effectiveness of the pill treatment were hailed as a "turning point" by experts when they emerged in April.
Dr Kosh Agarwal, from the Institute of Liver Studies at King's College London, who took part in the research, said: "Over the last decade we have seen an alarming rise in the number of deaths and hospital visits caused by people with hepatitis C.
When daclatasvir is combined with interferon-alpha and the pill drug ribavirin, it can cure 100% of patients with the less common genotype 4 strain of the virus.
Johanna Mercier, general manager of the pharmaceutical company Bristol-Myers Squibb in the UK and Ireland, which makes the drug, said: "We are committed to improving the quality of life of patients living with hepatitis C and paving the way to cure this chronic and devastating condition. In January daclatasvir was brought forward for priority review by the European Medicines Agency (EMA) in recognition of the unmet treatment need. The drug belongs new to a new family of pharmaceuticals called NS5A inhibitors which target a specific protein in the hepatitis C virus. However, if the virus moves into the chronic stage, your liver will become inflamed permanently, which will lead to cirrhosis. Chronic hepatitis C, clinically speaking, has a habit of only being found by accident as it can go years without any symptoms at all. Chronic Hepatitis B, it's called the silent killer and it affects millions of people around the world. Symptoms of hepatitis B can be pretty mild as around 30% of people infected have no early symptoms. Knowing you have an STD is probably going to be a private part of your life you wouldn't want everyone to know about, so we've put together a small tutorial on how to erase you browsing history in a number of popular browsers so whoever sits down at the computer next won't suddenly start asking unwanted questions about your medical condition. Multiple sclerosis (MS) is an autoimmune disease in which the body's immune system attacks its own central nervous system (CNS), which is made up of the brain and spinal cord.
The exact cause of multiple sclerosis is unknown, but it is believed to be any combination of immunologic, environmental, infectious, or genetic factors. Multiple sclerosis (MS) is an autoimmune disorder where the body perceives its own myelin (the sheath around the nerves) as an intruder and attacks it, as it would a virus or other foreign infectious agent.
There are four different types of multiple sclerosis that have been identified and each type can have symptoms ranging from mild to severe. Relapsing-remitting multiple sclerosis (RR-MS) is the most common type of MS, affecting about 85% of sufferers.
Primary-progressive multiple sclerosis (PP-MS) is characterized by steady worsening of neurologic functioning, without any relapses or remissions. Secondary-progressive multiple sclerosis (SP-MS) is a form of MS that follows relapsing-remitting MS. Progressive-relapsing multiple sclerosis (PR-MS) is the least common form of MS, occurring in about 5% of patients. Symptoms of multiple sclerosis may be single or multiple and may range from mild to severe in intensity and short to long in duration. Multiple sclerosis is often difficult to diagnose as symptoms are so varied and can resemble other diseases. One of the main ways to diagnose multiple sclerosis is an MRI (magnetic resonance imaging). Corticosteroids are drugs that reduce inflammation in the body and affect the function of the immune system. Continued from the last slide, this table lists common multiple sclerosis symptoms, and the treatments often used, along with possible complications. There has been a lot of progress over the years in managing multiple sclerosis, and research is ongoing into new therapies.
Multiple sclerosis (MS) is an autoimmune disease that progressively damages the nerves of the brain and spinal cord. Any sensory or motor (muscular) function in the body may be affected by the nerves damaged from MS.
There are four different types of multiple sclerosis and symptoms range from mild to severe. A repurposed drug that reverses some of the rapid-aging symptoms of Hutchinson-Gilford progeria syndrome also extends life, according to a new report in the journal Circulation.
The drug lonafarnib alters the morphology (lower right) of the nuclear membranes in cells from children with progeria.
The work of the PRF led to finding mutations in the lamin A gene that cause progeria, and that revealed the mechanism, which in turn led to realization that a shelved pediatric cancer drug, lonafarnib, targeted the same pathway. The short version: A class of drugs called farnesyl transferase inhibitors would remove a small organic molecule, farnesyl, from one end of lamin A protein. Normally lamin A forms part of the scaffolding that hugs the inner face of the nuclear membrane, contacting the threads of DNA and their associated proteins (chromatin) in the nucleus. The early results reported in 2012 were incremental, yet definitely steps in the right direction.


The new study underscores the importance of knowing the natural history of a disease – what happens, when, and for how long. The trial began in 2007 with 28 children from 13 countries, and at first evaluated only lonafarnib.
It can be both acute, lasting less than six months and healing on its own, or chronic, lasting longer and can be fatal. Over 85% of adults who get the virus will build up the appropriate anti-bodies and fight it off.
Although there is chance of the virus being fatal, a low percentage of cases turn out this way. Like all forms of hepatitis, your liver becomes inflamed, impairing its ability to work effectively. If results come back positive, your doctor will identify which type it is and offer you the best course of treatment. People in industries such as food preparation, daycare centers, and health care are the prominent people that can spread hepatitis A. Hepatitis B is a virus that attacks your liver which causes inflammation and is the most common serious liver disease in the world.
Around three and four million people have this deadly disease in the US and don't even know it. With MS, the immune system attacks and damages or destroys the myelin, a substance that surrounds and insulates the nerves, causing a distortion or interruption in nerve impulses traveling to and from the brain. Most people are diagnosed between the ages of 20 to 50, though it can also occur in young children and the elderly.
Researchers are examining the possible role of viruses in the cause of MS, but this is still unproven. This causes inflammation and degeneration of the myelin and can lead to demyelination, or stripping of the myelin covering of the nerves. The different types of MS can help predict the course of the disease and the patient's response to treatment.
RR-MS is defined by inflammatory attacks on the myelin and nerve fibers causing a worsening of neurologic function. There may be occasional plateaus, but overall the progression of the disability is continuous. People with PR-MS experience steady disease progression and worsening neurological function as seen in primary-progressive multiple sclerosis (PP-MS), along with occasional relapses like people with relapsing-remitting multiple sclerosis (RR-MS). Many medications carry the risk of some side effects so patients need to manage their treatment with their doctors.
This table (continued on the next slide) lists common multiple sclerosis symptoms, and the treatments often used, along with possible complications.
There are several new avenues of research including techniques to allow brain cells to generate new myelin or prevent the death of nerves. It is intended for general informational purposes only and does not address individual circumstances.
Prevalence is 1 in 18 million, reflecting the fact that average lifespan is only 14.6 years. The problem behind progeria is that farnesyl groups aren’t removed, as they should be, due to mutation affecting a splice site that would otherwise enable the group to be jettisoned.
With the farnesyl groups tenaciously hanging on, the altered architecture interferes with the chromatin, a little like poking one’s abdomen and jostling the intestines.
Progerin impacts DNA replication, RNA transcription, chromatin formation, cell division, apoptosis, and formation of the pores that let molecules in and out of the nucleus. Some children gained weight faster, their arteries grew thinner and more elastic, and their bones strengthened and hearing improved. The PRF patient registry identified 204 children, and information on them provided the control information to compare to effects on children given the drug.
Two years later the protocol added a statin (pravastatin) and an osteoporosis drug (zoledronate), with funding from PRF and the National Heart, Lung and Blood Institute. And that might be an underestimate, because many started the drug when they were far along.
But an extension of 1.6 years for someone with an average life expectancy of 14 years is impressive. But I’ll make an exception for the continuing success story of slowing down the runaway aging clock that is progeria. The author of several textbooks and thousands of articles in scientific, medical, and consumer publications, Ricki's first narrative nonfiction book, "The Forever Fix: Gene Therapy and the Boy Who Saved It," was published by St. There are many strands of the virus throughout the world today, however we will be focusing on the most common: hepatitis A, B, and C. Unfortunately, the virus can eventually lead to any number of conditions if left untreated, including liver cancer, cirrhosis, and fatal scarring of the liver. Washing hands properly is the most effective way to limit the spread of the disease as well as basic hygiene.
It is spread through sharing needles, toothbrushes, but is most commonly transmitted through unprotected sex.
It's important to get tested because if left untreated it can cause serious damage to your liver. People that need to be tested for hepatitis C include people that have had treatment for clotting problems prior to 1987, used and shared needles (around 80% of people that share needles will become infected with hepatitis C within the first year), and Blood transfusion or organ transplant before 1992.
It is three times more common in women than in men, and is more prevalent among Caucasians than other ethnicities.
Symptoms vary from patient to patient, and symptoms can flare up (called relapses or exacerbations) unexpectedly, and then disappear (remission).
This form of MS occurs equally in men and women, and the age of onset is about 10 years later than in relapsing-remitting MS.


After a period of relapses (also called attacks, or exacerbations) and remissions the disease will start to progress steadily. A physician will do a complete history and neurological exam, along with tests to evaluate mental, emotional and language functions, strength, coordination, balance, reflexes, gait, and vision.
On the left is a brain MRI of a 35-year-old man with relapsing remitting multiple sclerosis that reveals multiple lesions with high T2 signal intensity and one large white matter lesion. Other research involves use of stem cells that might be implanted into the brain or spinal cord to regrow the cells that have been destroyed by the disease.
It is not a substitute for professional medical advice, diagnosis or treatment and should not be relied on to make decisions about your health. He passed away at the age of 17 early this year, and was the subject of the HBO documentary Life According to Sam. It’s little wonder that a suite of symptoms ensue, the aging connection emerging perhaps as the misshapen nuclear membrane touches the telomeres (chromosome tips), somehow accelerating the shrinkage that marks biological time. And now that a few more years have passed, it’s clear that the drug is also extending the short lives of these children and adolescents. The researchers also consulted reports in the literature and databases to identify children to match with those being treated.
It is estimated that just over 3% of the worlds population carries a strain of the virus, most not even being aware of it.
If required, you doctor will give you a local anesthetic, and insert a small needle into your liver to retrieve a tissue sample, which they can then study under a microscope. It can easily be spread through the contact of fluids such as sharing a drink, touching foods, or even deep kissing. Provides prolonged disease freeinformation about treatments and symptoms, diagnosis, treatment,sep . MS is believed to have a genetic component as people with a first degree relative with the disease have a higher incidence than the general population. This causes electrical impulses to travel more slowly along the nerves resulting in deterioration of function in body processes such as vision, speech, walking, writing, and memory.
An identical twin of someone with MS has a 25% chance of being diagnosed with the disorder. The most common symptoms of RR-MS include fatigue, numbness, problems with vision, muscle spasms or stiffness, bowel and bladder function problems, and cognitive difficulties.

Some therapies being investigated include methods that would improve the nerve impulse signals. Never ignore professional medical advice in seeking treatment because of something you have read on the MedicineNet Site. The investigators hypothesize that the lonafarnib is extending life because of its effects on arteries. The researchers estimate that it will take at least 6 more years to confirm the survival benefit. In addition to writing, Ricki provides genetic counseling for parents-to-be at CareNet Medical Group in Schenectady, NY and teaches "Genethics" an online course for master's degree students at the Alden March Bioethics Institute of Albany Medical Center. It can lie dormant for decades, slowly eating away at your liver without any physical symptoms. In fact, 60% of the people who have contracted acute hepatitis C never even knew they had it, as it often goes misdiagnosed. For acute versions of the A and B strain, plenty or rest and fluids is all that is needed to clear out the virus.If you are infected with chronic hepatitis, your doctor may advise weekly injections of pegylated interferon alfa, along with twice-daily oral doses of ribavirin. There is a vaccination for the virus and it can be treated, but if you do contract it you can get very sick including nausea, jaundice, fever, and a swollen liver.
It is thought there is an outside trigger and genetics only makes certain people susceptible to getting MS which is why the disease is not considered hereditary – genes may make a person more likely to develop the disease but it is believed there still is an additional outside trigger that makes it happen. In addition the effects of diet and the environment on multiple sclerosis are being investigated. Gordon, from Hasbro Children’s Hospital of Brown University and Boston Children’s Hospital and medical director of the PRF, is first author of the new paper. In this article, we will examine the three strains in-depth, and provide pictures to better illustrate.Hepatitis A, the least severe of the three, is transmitted by a fecal to mouth route. With luck, the combined efforts of the medicine will clear the virus from the bloodstream completely, or at a minimum greatly slow the virus down.
People that already have issues such as liver or kidney problems are in a worse situation as it can become quite problematic.
The most common ways to become infected is consuming contaminated food or water, or sexually.
If your liver is fatally damaged, you will be put on a liver transplant list and await surgery.
If a donor is found in time, and the virus can be or has been cleared from your system, you can expect a full recovery.
Hepatitis B can be transmitted via blood transfusions, tattoos, sharing drug needles, and even from breastfeeding a child.
Although it's generally associated as an STD, or sexually transmitted disease, as that is the most common way to get it. However, this is the only way it can be transmitted.Hepatitis Symptoms Do I Have HepatitisHepatitis A takes between 15-45 days to between the time of infection, and the start of the illness. This strain of the virus does not have a chronic stage, and there exists a vaccination that will permanently prevent the illness.
