San Antonio, Texas (June 6, 2011)—A study introduced at SNM's 58th Annual Meeting may lead to the next wave of cancer imaging by helping to develop a molecular imaging agent that detects many malignant cancers' incessant development of blood vessels—a process called angiogenesis. A protein biomarker known as CD105 has been shown to indicate tumor angiogenesis in cancer patients.

San Antonio, Texas (June 6, 2011)—Researchers are halting kidney cancer with a novel form of radioimmunotherapy that zeroes in on antigens associated with renal cell carcinoma. Patients with progressive kidney cancer receiving up to three doses of the therapy show dramatic slowing of cancer growth and stabilization of their disease.
San Antonio, Texas (June 6, 2011)—Research introduced at SNM's 58th Annual Meeting could be a sign of hope for patients with neuroendocrine cancer not responding well to standard therapies. Most radiotherapies use medical isotopes that emit beta radiation. The therapy in this study employs alpha particles, which have potential for higher potency. In fact, one single atom could be enough to kill an entire cancer cell.
San Antonio, Texas (June 6, 2011)—Investigators at SNM's 58th Annual Meeting are presenting results from a phase 1 clinical trial for a cancer therapy that has the potential to kill colorectal tumors with less destruction of healthy tissue. Further research could lead to the use of this radioimmunotherapy to eliminate residual cancer after surgery or as a standard treatment to keep tumors from returning or spreading to other organs.
San Antonio, Texas (June 6, 2011)—Research presented at SNM's 58th Annual Meeting is taking targeted molecular imaging to a new level by combining two commonly used imaging agents into one molecular imaging procedure. The combination of these agents creates a comprehensive examination of the extent of cancer spread within a variety of organ systems in the body.
San Antonio, Texas (June 6, 2011)—A study presented at SNM's 58th Annual Meeting may provide a new tool for detection of malignant-stage ovarian cancer. Researchers found that positron emission tomography and computed tomography (PET/CT), which images both functional and anatomical changes in the body, was useful for preoperative cancer imaging of ovarian masses when used with a radiotracer that is actively metabolized by cells as fuel.
San Antonio, Texas (June 6, 2011)—A study revealed at SNM's 58th Annual Meeting is comparing the breast-tumor detection capabilities of two very different imaging technologies—breast-specific gamma imaging (BSGI), which provides functional images of breast physiology, and ultrasound—for women with complex breast imaging cases that require further evaluation. Many women who have dense breast tissue (radiodense breasts) are difficult to image using mammography, currently the gold standard of breast imaging.
Individuals with cancer often do not die as a result of their initial tumor but as a result of tumors at distant sites that are derived from the initial tumor. Pregnancy is a condition that seems to be permissive for tumor dissemination, as breast tumors arising during pregnancy display a tendency for early spread to distant sites (metastasis). Research in mice, led by Ivan Stamenkovic, at the University of Lausanne, Switzerland, has now uncovered a possible reason for this.
WINSTON-SALEM, N.C. – June 6, 2011 – A natural nutritional supplement, marketed for the last decade as a sexual aid, has been shown to significantly improve overall quality of life for female cancer survivors, according to researchers at Wake Forest Baptist Medical Center.
The findings will be presented today at the 2011 American Society of Clinical Oncology (ASCO) annual meeting in Chicago.
Terrorist groups bend the rules of 'true' Islam to justify the use of female suicide bombers, according to Margaret Gonzalez-Perez from Southeastern Louisiana University in the US. Her paper traces the development of radical Islamic doctrine over time, highlights how it deviates from mainstream Islam, and identifies the building blocks that have culminated in Jihadi female suicide bombers.
Cancer cells do not grow equally well everywhere in the body. Often, they first create the conditions in which they can grow. Many years ago researchers discovered that solid tumors attract blood vessels to ensure their supply of nutrients by secreting specific factors. Now the immunologist Dr. Uta Höpken (Tumor and Immunogenetics Research Group at the Max Delbrück Center for Molecular Medicine, MDC, Berlin-Buch in the Helmholtz Association) and the hematologist Dr.
A groundbreaking new test for male infertility, which will save time, money and heartache for couples around the world, has been developed at Queen's University Belfast.
The medical breakthrough, known as the SpermComet, has resulted from more than a decade's research by Professor Sheena Lewis, who leads the Reproductive Medicine research group at Queen's.
An article in the current issue of Global Change Biology Bioenergy finds that natural populations of Miscanthus are promising candidates as second-generation energy sources because they have genetic variation that may increase their stress tolerance.
Sustainable, large-scale bioenergy production requires domestication that develops crops capable of producing sufficiently high biomass on marginal and degraded land.
Back in the mid 19th century, a French doctor, Armand Trousseau, discovered a connection between cancer and thrombosis – the formation of often dangerous blood clots that can lead to venous occlusion. Today it is known that cancer and its treatment change blood flow properties and thus promote the formation of clots. However, clots do not only occur as a side effect and consequence of cancer, but, vice versa, an increased blood clotting tendency may also be associated with an elevated cancer risk.
A group of scientists at the Instituto Gulbenkian de Ciência, in Portugal, have uncovered a surprising link between the cell's skeleton and organ size. The team, led by Florence Janody, show in the journal Development(*), that one of the proteins that regulates the skeleton of the cell also acts to blocks activation of genes that promote cell survival and proliferation. Their findings have implications for cancer research, as they add to the puzzle of understanding how proliferation genes are abnormally activated, often leading to tumours.
