Abstract:
A printing head assembly for 3D printing and methods of using the same are provided. The printing head incorporates a backing means that can be shaped and positioned by use of an attractive force. This creates the possibility of embodiments in which the head can move in three dimensions, without the need to print each successive layer on the layer below. Methods of ensuring the security and integrity of the 3D printing process are also provided.
Abstract:
An illumination system incorporating a multi-faceted mirror in operative communication with an array of discrete illumination sources. The multi-faceted mirror may accept incident light beams from discrete illumination sources located at different positions and then deliver a reflected output to a common location for direct acceptance by an optical/imaging device or by a light guide transmission device operatively connected to a downstream optical/imaging device. Individual light sources may be selected and/or combined in a defined sequence by selectively activating and deactivating such light sources electronically with no need for moving parts. By pulsing different illumination sources, the optical/imaging system may be provided with a feed of narrow-band illumination for use in imaging. Outputs from several illumination sources can also be combined if desired to produce a custom-tuned illumination spectrum for a particular application.
Abstract:
The invention is a method of measuring salinity that presents an alternative to conventional salinity sensors that require AC voltage to measure salinity. The use of AC voltage is undesirable due to the need for two accurate analog measurements (current and voltage) and, in the case of computer based measurements both analog measurements must be converted to a digital signal.
Abstract:
The present invention is directed to compositions and methods of preserving viability of islets of Langerhans for transplantation, and treating various diseases and other abnormal or pathological conditions, including inflammatory bowel disease, ischemic heart disease, acute lung injury, acute respiratory distress syndrome and radiation- induced brain injury, with DNA repair enzymes that are directed to the mitochondria.
Abstract:
Substantially water-insoluble, crosslinked polypeptides containing 15 to 85 mole % of amino acid residues such as glutamic acid, aspartic acid, phosphoserine, phosphohomoserine, phosphotyrosine, phosphothreonine, phosphoasparagine, or phosphoglutamine, and 15 to 85 mole % of amino acid residues such as lysine, arginine, asparagine, glutamine, serine or tyrosine, in which the degree of crosslinking is sufficient to result in a substantially water-insoluble polypeptide with the ability to absorb a 1 wt.% aqueous NaCl solution in an amount of at least 20 times the weight of the polypeptide, are useful as superabsorbents in devices such as diapers, etc. Mild alkaline hydrolysis of the crosslinked polypeptides increases their superabsorbency by two to three fold.
Abstract:
The present invention relates to methods and compositions for detection of DNA damage, e.g. ., in a sample, cell or organism, that are amenable to high throughput, efficient and/or economical implementation, also capable of assessing a broad spectrum of DNA lesions.
Abstract:
The disclosure provides chemical compounds possessing therapeutic and/or protective properties against oxidative damage. Methods of making such therapeutic and/or protective compounds and associated compositions are also provided, as are methods for their use, which include protecting cells from oxidative damage and/or inhibiting production of ROS in a cell or subject, as well as preventing or reducing the extent of tissue damage caused by an ischemic event in a subject at elevated risk of such an event.
