The advantages of berries

...ree radicals - groups of atoms produced within the cell which otherwise may trigger the growth of a tumour. Black raspberries do contain an extraordinarily wide range of beneficial compounds - compared to other berries and fruits. They are full of anthocyanins, which give them their dark colour, phenols l...

Microwave radiation has no hazards

...t low-energy radiation emitted by radar detectors, cell phones and microwaves is different from extremely high-energy radiation like x-rays, which, as numerous studies have shown, can cause harm. Furthermore, he explained that the Navy veterans followed in this study were exposed to much more radiation th...

A new drug for bladder cancer

... A drug which is used for pancreatic and non-small cell lung cancer may also be applicable to bladder canc...s fever, pain on urination and reduced white blood cell counts. Gemcitabine works by blocking the growth of cancer cells. The scene is now set for larger tr...

Stem Cells Have Few Mutations

...udy, everybody has assumed that the embryonic stem cell had a mutation rate, we show that it is actually l...u find in the adult cells.// Peter J. Stambrook, a cell biologist at the University of Cincinnati and a co-author of the study, said that the most common em...

How to repeal male infertility?

... Inder Verma, used gene therapy to correct Sertoli cell dysfunction in mice. Their goal was to see if this could lead to sperm production and whether or not the sperm could be used to produce offspring. Researchers were also looking at whether or not the alteration would be passed on. Researchers correct...

New treatment for Rheumatoid Arthritis

...dent on the growth of new blood vessels that cause cell proliferation. This ongoing angiogenesis supplies nutrients and oxygen to growing tumors and can be inhibited //by a substance called endostatin. The angiogenesis observed in tumor growth is nearly identical to that of patients with rheumatoid arthri...

Enzyme stimulates growth of adult stem cells

...w to coax embryonic stem cells into desired mature cell types. This type of cloning is not intended to produce an offspring, but instead to produce an embryo that has stem cells are made specifically for treating a specific patient's disease....

Birth weight may be influenced by genes

...fluence on birth weight, since genetic material in cell powerhouses called mitochondria, which are found in the cytoplasm, are inherited only from the mother. Many factors are known to influence birth weight, such as nutrition, smoking, drug use and stress, but according to Ha, the results suggest that b...

Family planning with folate

...effect says, Judith. Folate is needed for healthy cell growth and development of men, women and children and folate is recommended in their daily diet. However it is also very important for women before and during the early stage of pregnancy to take folate as it is necessary for the healthy developmen...

Antioxidants found in chocolates

...release energy.// Unchecked, free radicals damage cell components like DNA and proteins, setting the scene for heart disease, cancer and other health problems. Antioxidants also help prevent blood clots and inflammation. The reason for recommending lots of fresh fruits and vegetables is because they co...

Stem cell transplantation of eye

...burns, damages the limbus resulting in limbal stem cell deficiency characterised by corneal blindness. The advantages of this procedure were use of patient's own tissue from the healthy eye to treat the diseased one avoiding the risk rejection, which is generally the case with cadaveric tissue....

Researchers find new HIV hiding place

... their findings show a type of NK (natural killer) cell a significant cell of the immune system could be infected by HIV. Not only do these cells get infected, they stay infe...

Developing HIV fighter

...arp's team made two different siRNAs that targeted cell surface proteins essential for the HIV virus to infect a cell. They targeted the parts of the virus that make the protein as well as a regulator protein. According to Sharp, in both cases we were able to show that these small RNAs in cells would inh...

Protection mechanism of fatty acids for Cancer

...C beta II (PKCbII) - which is linked with abnormal cell division. In this study, genetically-modified mice, which produce excess levels of PKCbII, were given a diet high in omega-3s. This measure was found to decrease the risk of these highly prone mice to that of normal animals. This new insight into h...

Photographs as a parameter

...o mass-screen patients.Strokes are caused by brain cell death due to bleeding from damaged blood vessels. Drugs that are effective at preventing stroke in high-risk patients are available, so doctors are keen to identify people with changes to their network of blood vessels - their vascular system - that ...

Hormone Therapy applicable for Prostate Cancer

Morphine may excite cancerous tumors

...d protein kinase (MAPK). MAPK promotes endothelial cell multiplication and angiogenesis, or formation of new blood vessels. Angiogenesis can cause tumor growth by providing nutrients to growing tumors and by transporting cancer cells from a tumor to other parts of the body. Lead researcher Kalpna Gupta, ...

Animal Fat increases risk Of stomach cancer

...pe of cancer of the esophagus--esophageal squamous cell carcinoma. Cholesterol, animal protein and vitamin B12, found primarily in animal products, were also associated with a higher risk of these cancers.
