Expression systems are disclosed for the direct expression of peptide products into the culture media where genetically engineered host cells are grown. High yield was achieved with novel vectors, a special selection of hosts, and/or fermentation processes which include careful control of cell growth rate, and use of an inducer during growth phase. Special vectors are provided which include control regions having multiple promoters linked operably with coding regions encoding a signal peptide upstream from a coding region encoding the peptide of interest. Multiple transcription cassettes are also used to increase yield. The production of amidated peptides using the expression systems is also disclosed.

The present invention provides a manufacturing method for the production of peptides that are grown in insect cell lines. The peptides are grown in insect cell cultures that are infected with baculovirus particles in a culture supplemented with a lipid mixture. The peptides are then isolated from the insect cell culture using a method that employs a tangential flow filtration cascade. The isolated peptides are glycopeptides having an insect specific glycosylation pattern. The glycopeptides may then be conjugated to a modifying group via linkage through a glycosyl linking group interposed between and covalently attached to the peptide and the modifying group. The conjugates are formed from glycosylated peptides by the action of a glycosyltransferase.

The present invention discloses a three-dimensional porous growth surface made from polysaccharide material, especially the alginic acid, to enhance cell growth surface, promote cell adherence, immobilization and propagation, maintain surface structure integrity, enable programmable degradation, and thus increase cellular production. The present invention teaches several methods: a method to enhance the integrity of the growth surface by protecting the growth surface in a rigid solid support; a method of use for enhancing the performance of the surface; and a method of modifying a growth surface for eukaryotic and/or prokaryotic cells comprising the steps of increasing surface area by creating porous and 3-D structure, treating a surface to encourage cell attachment, promoting cell growth and proliferation, and disposing the growth surface in any conventional cell cultivating device. The growth surface is able to program degradation and release the cell/tissue mass after the culture is completed.

The present disclosure provides compositions and methods for genomic engineering.

The invention discloses an air conditioner operation control method which comprises carrying out once or alternately carrying out a high-temperature sterilization process and a low-temperature self-cleaning process. The high-temperature sterilization process comprises controlling the heating operation of an air conditioner; and the low-temperature self-cleaning process comprises, to control the air conditioner, controlling an indoor unit to carry out frosting operation and defrosting operation in sequence. By the application of the air conditioner operation control method, self-cleaning treatment of sterilization and dust removal of the air conditioner is realized.

The invention discloses an air conditioner and a control method and device thereof. The control method comprises the steps of detecting the environment temperature of the space where the air conditioner is located; controlling the air conditioner to perform refrigeration running for a preset time according to the environment temperature to enable the air conditioner to form frost, judging whether the thickness of the formed frost meets the heating running condition or not; controlling the air conditioner to perform heating running when it is determined that the thickness of the formed frost meets the heating running condition. According to the environment temperature, the air conditioner is controlled to form frost, so that frost is formed to generate low temperature so as to lower the activity and survival ability of bacteria of an indoor unit, then the air conditioner is controlled to perform heating running to generate high temperature rapidly to kill the bacteria or lower the activity of the bacteria again, meanwhile, flowing water formed after a frost layer is molten by heating can bring away dust and bacteria, automatic cleaning and dust removal can be achieved, a running mechanism of the air conditioner does not need to be added, and the problems that due to an existing dust removal mode that a moving mechanism is added, the cost of the air conditioner is increased, and stability is low are solved.

An apparatus for sectioning fresh unfixed tissue into very thin layers with preserved tissue architecture, antigenicity, mRNA content, and amenable to 3-D computer reconstruction without mechanical or thermal damage by employing a sectioning tool having an electrode with an intense focused electrical field at an edge. A computer controlled x-y-z translation stage moves the sectioning tool through the tissue as defined by a predetermined program. The sectioning tool produces consecutive thin sections of fresh tissue for immunohistochemical and nucleic acids analyses without mechanical or thermal damage, ultimately allowing high-resolution volumetric reconstruction of gene and protein expression patterns of large tissue specimens. The geometry of the sectioning tool is selected so as to produce a spatially localized electrical field of sufficient intensity to sever molecular bonds or propagate flaws in tissue without mechanical cutting.

The present disclosure encompasses compositions comprising a surfactant, and an acid such as, but not limited to, levulinic acid, that together have a synergistic effect in reducing the viability of a virus population compared to the efficacy of the individual compounds. This synergy allows the formulation of compositions where the active agents (including an acid and a surfactant) are present at concentrations effective to inactivate viruses on surfaces, including human skin. The viricidal compositions disclosed herein are efficacious without damaging the surface to which they may be applied, or even altering the organoleptic properties of a treated food substance. The viricidal compositions and wipes containing such compositions are suitable for sanitizing any surface suspected of having a viral load thereon, or where it is desirable to ensure that a viral load is as low as possible.

The invention relates to HDAC inhibitors, or combinations comprising an HDAC inhibitor and a PI3K inhibitor for the treatment of non-hodgkin's lymphoma in a subject in need thereof.

Electronic coupons are loaded into a portable reader for electro-optically reading bar code symbols that identify products to be purchased. A coupon processor matches the identified product with an available coupon and confirms redemption of the coupon.

A low aspect ratio flying wing provides aerodynamic stability throughout the flight envelope with improved aerodynamic efficiency. Insufficient stability and reduced aerodynamic efficiency typical of low aspect ratio flying wings is improved through wing design and proper application and placement of horizontal stabilizers and boundary layer control. Lateral asymmetric boundary layer manipulation is employed to alter flying wing orientation in flight. Lateral extension and retraction of the main structure wing optimizes efficiency. This novel flying wing is not found in literature or “prior art” and provides improvement in aerodynamic stability and efficiency over previous designs. Given the large amount of research, literature, patents and activity in the field since the 1930's and the absence of a practical design indicates the non-obvious nature of these disclosures. In addition, those skilled in the art teach away from present disclosures failing to realize the better than predicted advantages.
