New optical microscope sees individual blood cells as they flow inside the body

Blood tests convey vital medical information, but the sight of a needle often causes anxiety and results take time. A new device developed by a team of researchers in Israel, however, can reveal much the same information as traditional blood test in real-time, simply by shining a light through the skin.

Scientists decipher structure of bacterial injection needles at atomic resolution

The plague, bacterial dysentery, and cholera have one thing in common: These dangerous diseases are caused by bacteria which infect their host using a sophisticated injection apparatus. Through needle-like structures, they release molecular agents into their host cell, thereby evading the immune response.

Deletion of 'lunatic fringe' promotes tumor formation of basal-like breast cancers

Multiple research projects - including a 2006 study conducted at the University of North Carolina at Chapel Hill - have used DNA microarray analysis to identify several breast cancer subtypes, including luminal A, luminal B, basal-like and HER2-enriched.

Regenerative medicine researchers explore innovative ways to treat childhood conditions

About 3 percent of the babies born in the United States have a birth defect. Children without a birth defect are also susceptible to injury or disease. At The University of Texas Health Science Center at Houston (UTHealth), regenerative medicine researchers are exploring innovative ways to treat these conditions.

Biomarker neutralizes effect of bevacizumab in pancreas and kidney cancer patients

Diether Lambrechts (VIB - KU Leuven) said "in two large clinical studies with patients with advanced stages of pancreas and kidney cancer a variant in the DNA was discovered that identified patients who did not respond well to the prescribed course of bevacizumab.

Study shows how a drug-lead compound suppresses tumour formation

A team of scientists from the National University of Singapore's (NUS) Department of Biological Sciences and Mechanobiology Institute have discovered how a drug-led compound - a compound that is undergoing preclinical trials as a potential drug - can deprive cancer cells of energy and stop them from growing into a tumour. This drug-led compound is named BPTES.

HS6ST2 enzyme an important regulator of breast cancer cell-bone interactions

Researchers from VTT Technical Research Centre of Finland have in collaboration with the University of Turku, Indiana University and two Finnish companies, Biotie Therapies Corp. and Pharmatest Services Ltd, discovered a novel mechanism regulating the development of breast cancer bone metastases and showed that heparin-like compounds can potentially be used to inhibit breast cancer metastasis to bone.

Study identifies biomarkers that predict patients' response to certain colon cancer drugs

The Stem Cells and Cancer Research Group headed by Dr H-ctor G. Palmer at the Vall d'Hebr-n Institute of Oncology (VHIO) has identified the molecular mechanisms that determine patients' response to certain drugs used in clinical trials for colon cancer treatment. The study led by VHIO also benefited from the collaboration with Professor Alberto Mu-oz-s laboratory at the Instituto de Investigaciones Biomedicas Alberto Sols, Consejo Superior de Investigaciones Cient-ficas.
