Transperineal Ultrasound-Guided Prostate Biopsy

Prostate cancer is the most common male cancer in the United States, and the third most common worldwide. Prostate biopsies are often performed to confirm a cancer diagnosis and examine suspect tissue. Prostate biopsies are most often performed under transrectal ultrasound imaging (TRUS) guidance. TRUS images in real-time, at relatively low cost, and shows both prostate and boundaries. However, major problems with TRUS imaging are poor spatial resolution and low sensitivity for cancer detection.

Robotic Exoskeleton for Treatment of Crouch Gait in Children with Cerebral Palsy (CP)

Crouch gait is a common disorder in pediatric cerebral palsy (CP). Effective treatment of crouch during childhood is critical to maintain mobility into adulthood. Current interventions do not alleviate crouch gait long-term for most patients. This technology relates to a powered exoskeleton designed for gait assistance. The powered assistance may provide a physical therapy-type intervention to improve and maintain mobility.  

Tni-FNL: An Improved Trichoplusia Ni Cell Line for Protein Expression

Researchers at the National Cancer Institute (NCI) have developed an improved insect cell line, Tni-FNL, derived from the cabbage looper, Trichoplusia ni.  The Tni-FNL cell line is capable of high level expression of heterologous proteins using baculovirus-based expression systems.  When compared to commercially available cell lines used for the same purpose, the Tni-FNL cell line often outperforms those for protein expression.  These cells have a high growth rate and are capable of growth at a lower temperature.

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.
