A new research has found that taking low-dose aspirin could reduce risk of cancer. This study has been published in the Lancet. Eight previous studies were reviewed for this study. All told, about 25,500 patients' information was included. This research is incredibly promising. There isn't really yet enough details for doctors to make a decision on aspirin therapy. Source for this article - Study links aspirin and cancer survival - don't start pills yet by Money Blog Newz. Aspirin might be able to stop cancer Today, the meta-study was published. A team or researchers in Britain published them. They said that taking aspirin every single day for five years redu…

I have some microscope slides with brain tissue slides on them. They have a glass cover slip over all of the slices. I'll do oil drop on them in order to observe, but when I'm cleaning up I have to use alcohol. It's been a while since I've walked into the laboratory, and it's difficult for me to get a hold of my supervisors. As such, anyone know which alcohol I should be using? Isopropanol? 70% ethanol? I cannot seriously recall nor reason as to why not to use one rather than the other.

Responses from physicians, scientists, or SFN members sought and welcomed.

I'm wondering about this. Mosquito biting is always harmful? Malaria, dengue, yellow fever, west nile virus are not very harmful disease for human. They are come from mosquito biting. But think about this. There is a mosquito which is not infected such disease, mosquito biting is all bad. How do we get immune capacity? We get immune capacity from vaccine injection or illness ... So, the mosquito biting which is not infected by harmful disease is not so bad for our health. How can we get the immune capacity for fighting cancer?

Imagine what would have happened to our world if there were no doctors to treat us from our diseases? The mortality rate would have increased and as such it would have tremendously affected the health of the nation. Scientific discoveries in the sphere of medicine have indeed come as a boon to human beings. One such discovery which has made quite a stir in the medicinal world is the discovery of umbilical cord blood stem cells and cord blood stem cells. The discovery of umbilical cord blood stem cells and cord blood stem cells have led to the prevention to a number of diseases which were other wise considered as incurable. Cord blood stem cell is the process of uti…

I have a Chinese friend who has lots of pustules and sometimes likes to pop them. I'm wondering whether doing this is healthy. Is it harmful in any way? Generally, is popping pustules a better alternative to not popping? What are the latest scientific evidence suggesting?

I tend to get what I would call cold symptoms, regularly if I go out on a cold day. Even after 20 minutes outside in the cold, I will regularly end up with cold-like symptoms. However, my wife insists on calling these symptoms (blocked nose, occasional sneezing) 'chills' rather than colds. So what is the matter? Do I manifest the symptoms of cold viruses inside me that have been 'waiting' inside me, or are these 'chills' related, instead, to inflammation of the mucus membranes of the nose which copy the effect of having an actual cold without all the symptoms

Humans can tolerate wide ranges of temperature variation. With increasing hot or cold, however, discomfort is reached and ultimately health problems may result. I'm wondering about the limits of sustainable indoor temperature. I have read about acclimatization studies where native Alaskans were observed to walk barefoot in very cold temperatures and were measured as shivering at lower temperatures than other students who did not engage in acclimatization practices. Does anyone know what the minimum consistent indoor temperature humans can tolerate without encountering health problems? Obviously clothing and other factors make a difference, but I would guess around 50…

Having checked out a few websites which suggest that diabetes increases the rate of heart disease, I am none the wiser. What is the mechanism that increases heart disease and is it diabetes Type I or II which is worse for a person's heart.

Hey, I've been using melanotan as a redhead, but you can find many other patents online to darken hair and skin without having to use the needles ( no dyes or sunless stains but really increasing melanin activity), what I'm currently looking for is a doctor, formulator, scientist,...that could help me on formulating those patents, calling the right people to see what kinda penetration agents they need,.... So I thought on a scientific forum might be people that could help me and all other users wanting to darken hair and skin. If you want to have some links, just contact me...

Is it unhealthy to crack your bones constantly (e.g. your fingers and toes)?

What is the difference between circulatory system and cardiovascular system? According to my knowledge, both are the names of same system of human body. Cardiovascular is more anatomic term and circulatory is more physiologic term. So the system to which anatomists refer as cardiovascular system, physiologists will call it circulatory system. For more details on my explanation of cardiovascular system vs. Circulatory system, see my blog post "Circulatory System vs. Cardiovascular System"

What can cause this or one eye farsighted in one eye and nearsighted in other eye ? I also have tinnitus it gets worse at night.

It is indeed a revelation in the medical world to have come up with something as cord blood stem cells to cure diseases. Cord blood stem cells which have been proven at healing severe illness are gaining popularity among parents who seem to be gearing up to this new found remedy by giving their umbilical cord blood for collection. It is a known fact that cord blood which is rich in stem cells, are often discarded at the time of child birth. With parents getting to know its benefits, they are now opting for umbilical cord blood donation, because diseases do not wait for a green signal to attack anyone. Having preserved this precious cord blood, you can take a sigh o…

My dear friends till yet most of us was in the wrong concept that Menstrual blood is just a wastage. But scientist found stem cells naturally from this menstrual blood. There are so many private cord blood banks with latest technology to collect, preserve the stem cells from the menstrual blood. As per my research I found Celle's patent-pending technology, and easy-to-use collection kit, you have the reassurance and peace of mind you need, when it comes to collecting, isolating and preserving menstrual blood. A graceful quote "Welcome to Celle – where every month holds a miracle". If you really liked my post as well as my research resource please repl…

Because of its important role in maintaining vascular health and promoting vasodilation, some have proposed that nitric oxide be regarded as an essential nutrient. I was wondering if anyone could suggest a good dietary source of nitric oxide donors or a nitric oxide donor supplement other than the well-known one of l-arginine?

I guess I'm one of those people. These days I notice that my sense of smell wasn't as strong as it was in the past. I could not no longer detect heavy odor and it came to my surprise that on one particular day, I couldn't even detect the cooking gas leakage until my sister highlighted to me. I guess not only is this bad but it might be dangerous in the long run. At the moment, I'm not going to seek medical advice as my worst fear is having to undergo operation. If anybody has any clue or advice, I would appreciate it. So far, my search in the internet did not really offer any lead. What I need maybe is herbal treatment or cure. thanks in advance guys.

Dear Ladies and Gentlemen, Nonspecific inflammation of lungs (pneumonia) in children is a significant problem in the world. In this regard, World Health Organization intends to spend 39 billions of dollars in 2010-2015 years only to prevent this disease (“New WHO/UNICEF action plan to tackle pneumonia”, November 2, 2009, www.who.com). I’d like to bring your attention to acute pneumonia (AP) with progressive tendency. There appears to be an inability of AP treatment to stop the development of inflammatory process and its complications. Although this patients’ group has been a regular subject of numerous publications, the purpose of this discussion is t…

Research injecting neural (adult) stem cells into the brains of dogs has shown to be very successful in treating cancerous tumors.Using conventional techniques, brain cancer is difficult to treat because it spreads so rapidly. Researchers at the Harvard Medical School transplanted human neural stem cells into the brain of rodents that received intracranial tumours. Within days, the cells migrated into the cancerous area and produced cytosine deaminase, an enzyme that converts a non-toxic pro-drug into a chemotheraputic agent. As a result, the injected substance was able to reduce the tumor mass by 81 percent. The stem cells neither differentiated nor turned tumorigenic. S…

Hi: I’m currently thinking of a hypothetical diet product that is vegan-friendly and has all the vegetables, fruits, herbs, algae, seaweed, mushrooms and other non-animal organisms that are necessary/beneficial for human health. It also contains beneficial and essential microbes [such as probiotics]. All the aforementioned are in amounts optimum for human health. This product is completely organic and free of any pesticides, synthetic ethylene and other man-made substances that compromise the health of organisms and their human consumers. In addition, no organisms used in the product are genetically-engineered, pasteurized, or irradiated to any extent. Equally im…
