The tumor protein p53 is a cell cycle regulator. It responds to DNA damage by triggering the DNA repair pathway and allowing cell division to occur or inducing cell growth arrest, cellular senescence, and/or apoptosis. p53 therefore acts as a tumor suppressor by preventing uncontrolled cell division. However, mutations in p53 that impair its cell cycle regulatory functions can induce uncontrolled cell division leading to cancer.
Molecular imaging is a disease-specific targeting modality that promises much more accurate diagnoses of serious diseases such as cancer and infections. Agents are being continually developed with a view to clinical translation, with several such therapies requiring measurement of very small doses. Currently, there is no way of accurately measuring small amounts of radioactivity used in many pre-clinical tracer studies, as on-the-market commercial dose calibrators measure at too high a dose range, typically at 10-1000 µCi and higher.
The ability to hold and transport tissue, especially needle biopsies in a pre-defined and controlled environment is critical for the preservation of biopsy samples in downstream analytic applications. Currently, tissue specimens are placed in open containers with variable, poorly controlled solutions applied to them, often in less than sterile conditions. Evaluation of the tissue by examination through a stereoscope or similar approaches to determine adequacy is limited and requires manipulation of the tissue that can further damage the tissue.
Virus entry into a susceptible host cell is the first step in the formation of all viral diseases. Controlling viral infections by disrupting viral entry is advantageous for antibody-mediated neutralization by the host’s immune system and as a preventive and therapeutic antiviral strategy. Plant-derived carbohydrate-binding proteins (lectins) have emerged as a new class of antiviral biologics by taking advantage of a unique glycosylation pattern only found on the surface of viruses.
GSD-Ia is an inherited disorder of metabolism associated with life-threatening hypoglycemia, hepatic malignancy, and renal failure caused by the deficiency of glucose-6-phosphatase-alpha (G6Pase-alpha or G6PC). Current therapy, which primarily consists of dietary modification, fails to prevent long-term complications in many patients, including growth failure, gout, pulmonary hypertension, renal dysfunction, osteoporosis, and hepatocellular adenomas (HCA).
