A Novel Demodulation System in X-ray Imaging

In various x-ray imaging methods, including scattering correction and phase contrast imaging, intensity modulation in space is introduced into the projection images by the use of masks, gratings, or apertures. The present invention relates to a process to demodulate the modulation. The current demodulation processes are either to remove the modulation pattern through digital processing or to move the modulation pattern on the detector in a series of images that requires mechanical movements of a component and tends to lose some information of the imaged object.

Resolution Enhancement for Light Sheet Microscopy Systems

The invention pertains to a technique for enhancing the resolution of images in light sheet microscopy by adding additional enhanced depth-of-focus optical arrangements and high numerical aperture objective lenses. The technique employs an arrangement of three objective lenses and a processor for combining captured images. The image composition utilizes the greater resolving power of the third high numerical aperture objective lens by imaging the light sheet and enhanced depth-of-focus arrangement resulting in improved overall resolution of the light sheet system.

LRRK2 Inhibitors: Novel Treatment for Intestinal Bowel Disorders

Use of Leucine Rich Repeat Kinase 2 (LRRK2) inhibitors for the treatment of Intestinal Bowel Disorders (IBD) is disclosed. IBD is a broad term that describes conditions with chronic or recurring immune response and inflammation of the gastrointestinal tract. Crohn's disease and ulcerative colitis, two common forms of idiopathic IBD, are chronic, relapsing inflammatory disorders of the gastrointestinal tract.

CXCR4 Reduction Leads to Enhancement of Engraftment of Hematopoietic Stem Cells

Methods of enhancing engraftment of donor hematopoietic stem cells (HSCs) by reducing expression or activity of CXCR4 in HSCs is described. HSC are the only cells in the bone marrow that are both pluripotent and long lived. Bone marrow transplantation (BMT) using HSC is an increasingly common medical therapy for severe hematologic cancers and primary hematologic immunodeficiencies. However, for significant HSC engraftment to occur there must usually be pre-transplant conditioning with either irradiation or chemotherapy or both.

A Novel Therapeutic Vector for Hemoglobin Disorders

Investigators at the National Heart, Lung, and Blood Institute have designed a novel lentiviral vector as a potential gene therapy for sickle cell anemia and beta-thalassemia. The novel lentiviral vector encodes the beta-globin gene in a forward orientation and can produce 5-10 fold higher viral titer and 4-10 fold higher gene transfer efficiency to hematopoietic stem cells than reverse-oriented lentiviral vectors. In vivo studies conducted in rhesus macaques show beta-globin production after transplantation with this novel lentiviral vector.

Swing-Away Winch Cathead Guard

Shrimp boat operators use two trawl retrieval mechanisms mounted on the same winch frame. The main spools are used in the first operation; the shrimpers stand within inches of rotating cathead drums and guide incoming wire rope onto the main spools. Second, lazy lines are wrapped multiple times around each of the two spinning catheads (horizontal beams that raise and secure the anchor). Lastly, the guarding ends are pulled by the operators to cinch the rope to the rotating spool aiding trawl retrieval, but poses a hazard for operators to get entangled in the spinning cathead spools.

Emergency Maritime Battery Charger

Boats and other watercrafts have emergency lifesaving equipment like strobe lamps to help rescuers locate individuals overboard in the event of a disaster. The battery life of the equipment is limited, so the amount of time rescuers have to find the victims is also limited. An emergency battery charger that can power emergency equipment is needed to remove this limitation.

SIRT1 KO Human Cell Lines Generated by CRISPR/Cas9-mediated DNA Editing

SIRT1, a NAD+-dependent protein deacetylase, is the most conserved member of the sirtuins family. Through deacetylation of a number of protein substrates that are important transcription factors or co-factors, SIRT1 regulates many vital biological processes such as metabolism, cellular stress response, stem cell pluripotency, and development.

Mouse Model for Study of Diabetic Nephropathy and Role of Soluble Epoxide Hydrolase

Diabetic nephropathy (DN) is the leading cause of renal failure and is characterized by proteinuria that progresses to renal inflammation and decline in the glornerular filtration barrier (GFB). Podocytes are specialized epithelia cells in the glomerular capsule that have a role in filtration of blood and maintaining the integrity of the GFB; dysfunction of these cells plays a significant role in the pathogenesis of DN. Soluble epoxide hydrolase (sEH) is a cytosolic enzyme whose inhibition has beneficial effects in inflammatory diseases.
