Autoantibodies can potentially detect lung cancer at early stage

Preliminary research has identified autoantibodies, immune proteins found in the blood specific for one's own proteins, that can potentially detect lung cancer early by distinguishing between smokers with or without lung cancer and also discriminate between lung cancer and low-dose computed tomography (LDCT) detected non-cancerous lung lesions.

Eating one portion of fish a week helps reduce dementia risk

Eating at least one portion of fish per week helps to reduce a person's risk of developing Alzheimer's disease and dementia-related illnesses. This was evidenced by international research conducted at the Rush University Medical Center in Chicago and published in the Journal of American Medical Association (JAMA).

Researchers reveal how brain-specific microRNA plays key role in causing abnormal brain development

Autism Spectrum Disorders (ASDs) are a group of highly inheritable behavioural disorders that pose major personal and public health concerns. Patients with ASDs have mild to severe communication difficulties, repetitive behaviour and social challenges. Such disorders significantly challenge an individual's ability to conduct daily activities and function normally in society. Currently there are very few medication options that effectively treat ASDs.

Studies explore causative factor of hypertension in younger, obese men and women

There's no doubt estrogen plays a big role in the differences between males and females, and now researchers want to know if it also helps explain emerging sex differences in what makes younger, obese men and women hypertensive.

Patterns of philopatry and longevity contribute to menopause, study suggests

The evolution of the menopause was 'kick-started' by a fluke of nature, but then boosted by the tendency for sons and grandsons to remain living close to home, a new study by Liverpool scientists suggests.

New optogenetic technology could turn on immune cells to attack melanoma tumors

A new optogenetic technology developed at UMass Medical School, called optogenetic immunomodulation, is capable of turning on immune cells to attack melanoma tumors in mice. Using near-infrared light, UMMS researchers have shown they can selectively activate an immune response by controlling the flow of calcium ions into the cell. This breakthrough could lead to less invasive, and more controlled and selective, immunotherapies for cancer treatment.

NUS-led study reveals key player contributing to maintenance of hematopoietic stem cells

A study led by scientists from the Cancer Science Institute of Singapore (CSI Singapore) at the National University of Singapore has uncovered a key player contributing to the maintenance of hematopoietic stem cells (HSCs), blood cell precursors which have the ability to become any type of blood cell in the body.

FAU researchers find mechanism that promotes metastasis and causes tumours to resist treatment

Fast metastasis and resistance to treatment are characteristic of aggressive types of cancer such as pancreatic cancer and certain kinds of breast cancer. They are also the main causes of cancer-related death, as there is currently no specific treatment available that is able to stop tumours spreading throughout the whole body. Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg have recently made a discovery that could change this.

Wistar researchers find potential way for using STAT3 inhibitors to stop cancer progression

Imagine developing a drug designed to inhibit a protein that helps cancer cells proliferate and survive only to find that the drug does not perform very well in the clinic. This was the dilemma faced by scientists researching inhibitors of signal transducer and activator of transcription (STAT3), a protein that controls transcription by the STAT3 gene.

Small chemical change to existing antibacterial drug may result in better treatment for TB

Researchers with Vanderbilt University have discovered that one small chemical change to an existing antibacterial drug results in a compound that is more effective against its target enzyme in tuberculosis.

Isomaltulose more suitable than table sugar for people with type 2 diabetes

Potsdam-Rehbruecke - Like sucrose (table sugar), the natural disaccharide isomaltulose (PalatinoseTM) consists of glucose and fructose, but it is apparently more suitable for people with type 2 diabetes with regard to regulating blood glucose levels.

Small peptide TAxI holds promise for carrying biologic drugs into spinal cord

A small peptide dubbed TAxI is living up to its name. Recent studies show it to be an effective vehicle for shuttling functional proteins, such as active enzymes, into the spinal cord after a muscle injection.

Study reveals another clue to workings of trachoma

Another clue to the workings of trachoma - the world's leading infectious cause of blindness - has been revealed in a new study published in BMC Infectious Diseases. Researchers identified markers of genetic regulation present in the early stages of infection that could predispose children to developing the condition in its long-term, severe form.

New study could help explain critical shortcomings in stem cell-driven therapies for heart disease

With every heart attack, billions of cardiomyocytes, the contracting heart muscle cells that make the heart pump time after time over a lifetime, are lost which can lead to heart failure or injury. Stem cell-based replacement strategies could open new and much needed therapeutic avenues.

Green tea compound has high potential as treatment for rheumatoid arthritis

Researchers at Washington State University in Spokane have identified a potential new approach to combating the joint pain, inflammation and tissue damage caused by rheumatoid arthritis.

Synthetic RNA and DNA could reverse protein deficiency that causes Friedreich's ataxia

Researchers at UT Southwestern Medical Center have identified synthetic RNA and DNA that reverses the protein deficiency causing Friedreich's ataxia, a neurological disease for which there is currently no cure.

Study shows new RNA letter as regulatory key to control gene expression

DNA, RNA, protein -- the end. Or is it? Until recently, the pattern used to encode genetic information into our cells was considered to be relatively straightforward: four letters (A,G,C,T) for DNA and four (A,G,C,U) for RNA. This equation, however, turned out to be oversimplified -- RNA was holding out.

Penn researchers use network science to gain new insights into torn ligament

When doctors diagnose a torn ligament, it's usually because they can see ruptures in the ligament's collagen fibers, visible on a variety of different scans. However, they also often treat patients with many of the symptoms of a tear, but whose ligaments don't show this kind of damage.

Researchers discover factor that controls embryonic stem cell development

After a gestation period of around ten months, fawns are born in early summer - when the weather is warm and food is plentiful for the mother. Six months would actually be enough for the embryo's development, but then offspring from mating in the later portion of summer would be born in winter.
