An adaptive cushion for reducing pressure on body parts of a person positioned on a chair or bed includes an overlay cushion having a plurality of individual air bladder cells, each having thereon a force sensor. The cushion includes a controller for inflating and deflating individual air bladder cells to air pressures that tend to reduce the interface pressures sensed by the force sensors. A pressure reduction method includes varying the inflation pressure in a first air bladder cell while measuring the sum of the interface pressures exerted on all or a plurality of the air bladder cells, re-pressurizing the first cell to that air pressure for which a minimum total interface pressure was obtained, repeating this process for the remaining air bladder cells.

An air mattress apparatus includes an air mattress which comprised of an array of air bladder cells that are individually inflatable to quiescent pressure levels which provide comfortable support for the body of a human, and a pressure-pulse generator controlled by a wave sequence generator for introducing into ordered patterns of air bladder cells a wave-like time sequence of air pressure pulses which vary quiescent pressure levels in the cells, the pressure wave resulting in a traveling wave of support force variation which travels over the surfaces of the pulsed air bladder cells, thus inhibiting formation of bedsores. The wave pattern may optionally simulate water waves and / or rocking motions of a boat to produce relaxing effects.

Disclosed are methods for determining the methylation status of the promoter region of the TWIST1 gene in genomic DNA from bladder cells, including bladder cells present in a urine sample. Also disclosed are kits for performing the disclosed methods, such as kits for determining the methylation status of the promoter region of the TWIST1 gene comprising at least one primer pair for determining the methylation status of TWIST1. The kits may contain means for processing a urine sample.

The present invention provides methods for imaging and the treatment of cancer. In certain embodiments, a polyarginine (e.g., R11) may be used to selectively image prostate or bladder cells (e.g., a metastatic prostate cancer). In other embodiments, a DOC-2 / DAB2 peptide, optionally conjugated to a cell permeable peptide (e.g., R11) may be used to treat a cancer, such as prostate cancer.

A traveling wave air mattress apparatus includes an air mattress comprised of an array of laterally disposed, longitudinally spaced air bladder cells that are individually inflatable to quiescent pressure levels which provide comfortable support for a human body, and an air pressure-pulse generator controlled by a wave sequence generator for periodically introducing into sequences of the air bladder cells timed sequences of air pressure pulses which vary pressures in the cells from quiescent pressures, the air pressure variations resulting in leading and lagging soliton-like traveling waves of body support force variation which travel longitudinally over the surfaces of the pulsed air bladder cells, thus inhibiting formation of bedsores. The wave patterns may optionally simulate water waves and / or rocking motions of a boat to produce relaxing effects.

Composition and methods are disclosed for utilizing microaggregation of FAP-containing complexes to promote their fast internalization. This approach allows the uptake of cytotoxic cargo coupled to either FAP-Antibodies or FAP-liposome complexes by tumor bladder cells. Importantly, this approach is efficient even under serum-free conditions such as the ones found in the lumen of the bladder.

The present invention relates to compositions comprising therapeutic and / or diagnostic anionic agents together with cationic peptides and their use in methods for delivering the anionic agents to bladder cells.

The invention relates to a method for constructing an air bladder cell system of blotchy rockcod, which comprises: taking an air bladder tissue of the blotchy rockcod as a material to start primary culture, and culturing the air bladder tissue in a DMEM / F12 liquid medium which contains fetal calf serum, carboxymethyl chito-oligosaccharide, basic fibroblast growth factors, I-type insulin-like growth factors, N-acetyl glucose hydrochloride and culture supernatant of heart cells of the blotchy rockcod in the log phase and has a pH value of between 7.0 and 7.4; and adopting a trypsin digestion method for subculturing. The air bladder cell system of the blotchy rockcod constructed by the method is subcultured for 62 generations currently. The technology is scientific and reasonable, is hopefulto be applied to ecotoxicological research, performs pollution monitoring and safety evaluation on various environmental pollutants in the sea, and can also be applied to separation, identification and in vitro breeding of fish viroids, and research in the aspects of interaction of viruses and host cells, and so on.

A method of detecting a predisposition to, or the incidence of, bladder cancer in a sample comprises detecting an epigenetic change in at least one gene selected from FOXE1 and GATA4. Detection of the epigenetic change is indicative of a predisposition to, or the incidence of, bladder cancer. The sample comprises nucleic acid molecules from bladder cells. The methods may be used to select treatments and patients for treatment. Related kits include primers allowing the methylation status of the genes to be determined.

The invention relates to a hair cultivation essence of natural plant ingredients extracted from more than 10 rare Chinese medicinal herbs, which is prepared through ultrasonic extractive technique and ultrasonic homogenization techniques for the traditional Chinese medicines, and by adding silk peptide, tyrosine, cystine and natural vitamin A, wherein the hair health product can be orally administrated or used externally. The product can activate bladder cells and stimulate the blood circulation on head.
