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.

The technology relates to software, systems, and methods for automated medical image segmentation via deep learning. Standard holistically-nested networks (HNNs) used in computer vision and medical imaging for segmentation and edge detection have a problem with coarsening resolution. The described technology addresses this.
 

Ultrasound-based cancer screening and biopsy imaging technologies are a clinical need. Ultrasound based biopsy imaging can provide a real-time modality for lower cost that is comparable to, or complimentary to MRI imaging.  This technology may enable more accurate, less costly and more accessible cancer screening.

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.

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.

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. 

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. 

The AKT pathway plays a key role in the regulation of cellular survival, apoptosis, and protein translation and has been shown to have prognostic significance in a number of cancers.  Recently, the inventors have identified several functions of the AKT pathway in certain cancers, such as extrahepatic cholangiocarcinoma (EHCC).

GISTs are one of the most common sarcomas of the gastrointestinal tract with an estimated 5,000-10,000 new cases in the U.S. reported each year. GISTs affect mainly pediatric and young adult patients, and respond poorly to current therapies. Paragangliomas are rare neuroendocrine neoplasms that develop primarily in the abdomen.

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.
