Systems and Devices for Training and Imaging an Awake Test Animal

Typical MRI imaging sessions can last over 45 minutes and depend on the subject remaining still during the procedure for accurate imaging. In particular, animals being imaged, such as rodents (rats) in an awakened state, are not readily compliant with the restricted movement required when being imaged. Current techniques for imaging awake animals focus on training them with full body restraints and head fixation using a bite bar and/or ear bars.

A Sensitive, High Throughput Pseudovirus-Based Papillomavirus Neutralization Assay for HPV 16 and HPV 18

Human Papilloma Viruses (HPV) is a very common virus; nearly 80 million people—about one in four—are currently infected in the United States. HPV is a group of more than 150 related viruses. Each HPV virus in this large group is given a number which is called its HPV type. HPV is named for the warts (papillomas) some that HPV types can cause. Some other HPV types can lead to cancer, especially cervical cancer.

Device to guide oxygen over cells for photo-oxidation

Researchers at the NCI Laboratory for Cell Biology have invented a device to guide a stream of oxygen or carbon dioxide over a dish of cells during fluorescence microscopy. The invention includes the 3D printing software to create the device.  The device facilitates application of a steady source of oxygen or carbon dioxide to cells while operating a fluorescent microscope to oxidize fluorophores for subsequent visualization via electron microscopy. 

Device for Growing Mammalian Cells on EM Grids

Researchers at the NCI Center for Molecular Microscopy invented a device to hold transmission electron microscopy grids that allows adherent mammalian cells to be grown on it, as well as the 3D printing software to create the holder.  The TEM cell grid holder solves the difficulty of lifting the TEM grid out of a plate without bending or damaging the grid.  The holder can be reproduced in various sizes with 3D printing. 

Radiographic Marker for Portable Chest and Abdominal X-Rays

The NIH Clinical Center seeks parties interested to license a method and apparatus that can significantly improve the diagnostic performance of portable chest (CXR) and abdominal x-rays.  This device (see image below) quantifies angulation of a patient to provide for a better comparison of day-to-day improvement. Potential applications include portable chest and abdominal x-rays performed at patient's hospital bedside.

Optical Microscope Software for Breast Cancer Diagnosis

The successful treatment of cancer is correlated with the early detection of the cancerous cells. Conventional cancer diagnosis is largely based on qualitative morphological criteria, but more accurate quantitative tests could greatly increase early detection of malignant cells. It has been observed that the spatial arrangement of DNA in the nucleus is altered in cancer cells in comparison to normal cells. Therefore, it is possible to distinguish malignant cells by mapping the position of labeled marker genes in the nucleus.
