The invention provides the use of mesenchymal stem cells for preparing drugs/medicines for the treatment of non-healing burn wounds. The inventor found that the mesenchymal stem cells of the present application are used to treat burn wounds and have significant curative effects. They can effectively promote the repair of hard-to-heal burn wounds, increase the healing rate of hard-to-heal burn wounds, and shorten wound healing time, with non-toxic side effects, easy absorption and other advantages. Therefore, the mesenchymal stem cells and the composition containing them can be used to prepare drugs/medicines for treating non-healing burn wounds.

Genetically engineered bacteria, pharmaceutical compositions thereof, and methods of treating or preventing autoimmune disorders, inhibiting inflammatory mechanisms in the gut, and/or tightening gut mucosal barrier function are disclosed.

The invention is directed to a hypertension animal model, and methods of using the same to induce heart failure with preserved ejection fraction (HFpEF) responses.

Disclosed herein are compositions and in vitro and in vivo methods for reprogramming post-natal (adult and juvenile) tissue into insulinogenic cells. These compositions and methods are useful for a variety of purposes, including the development of diabetes therapies.

A hybrid composite and method for producing a polymer network are provided. The hybrid composite includes nanocrystalline hydroxyapatite (nHA) and polyurethane. The method for producing a polymer network includes reacting nanocrystalline hydroxyapatite (nHA) particles with lysine derived triisocyanate (LTI) to form a nHA/LTI hybrid prepolymer and reacting the prepolymer with a thioketal (TK) diol to form a nHA/poly(thioketal urethane) (PTKUR) hybrid polymer network.

The present invention relates to a method for producing an animal model of preterm birth and an animal model of preterm birth produced by the method. The animal model of the present invention can be effectively applied to investigate the causes and symptoms of preterm birth induced by cervical injury. The mortality rate of the animal model according to the present invention is low until preterm birth despite its induced preterm birth. In addition, the animal model of the present invention is produced in a higher yield than any other existing model. Furthermore, the preterm birth of the animal model according to the present invention is induced at a desired time point. Due to these advantages, the animal model of the present invention can be effectively applied to investigate the causes and mechanisms of preterm birth. The mortality rate of premature neonates born from the animal model of the present invention is considerably low and the premature neonates are immature. Therefore, the animal model of the present invention can be effectively applied to studies on complications of premature neonates.

The present invention relates to a method for generating sterile Zeugodacus scutellata males by emitting an electron beam at a dose of 150 Gy (inclusive) to 250 Gy (exclusive) to pupae of Zeugodacus scutellata and a method for controlling Zeugodacus scutellata by releasing the generated sterile males and normal males at a ratio of 9:1. In the present invention, electron beams are used instead of radioactive beams and suitable doses of electron beams are determined to generate sterile males of domestic native Zeugodacus scutellata. The generated sterile Zeugodacus scutellata males and normal males are released at a ratio of 9:1 to effectively control Zeugodacus scutellata through a sterile insect release technique (SIT).

Disclosed is a method for culturing urine-derived kidney stem cells, which belongs to the field of cell biology. The method comprises the following steps: isolating cells from the urine, and then culturing the cells with a culture medium of urine-derived kidney stem cells on feeder cells to obtain the urine-derived kidney stem cells, wherein the feeder cells are fibroblasts, and the culture medium of urine-derived kidney stem cells contains 200-300 mL of DMEM medium, 200-300 mL of F12 medium, 20-70 mL of fetal bovine serum, 0.2-2 mM of L-glutamine, 1-14 ng/mL of insulin, 0.1-1 ng/mL of epidermal growth factor, 5-30 μg/mL of adenine, and 2-20 μg/mL of hydrocortisone. By using the method, kidney stem cells with high proliferation capacity and specificity can be obtained and applied, and thus the regenerative outcome of the kidney tissue after injury can be improved.

A system for treating cancer and evaluating chemo-preventive potential of PHC and its prepared chitosan nanoparticles is described. The rats are divided into eight groups, from which group 1 is served as normal control, and group 2-8 are given single dose of DEN and repeated dose of CCl.sub.4, wherein freshly prepared solution of DEN in normal saline is used for the induction of HCC in rats by administering 200 mg/kg, i.p., PHC (2:1:1) in normal saline suspension to administer at doses of 900 mg/kg, wherein serum and tissue samples are collected after anesthetizing overnight fasted rats using intraperitoneal administration of thiopentone sodium at a dose of 40 mg/kg, wherein the collected serum and tissue samples is treated and thereby the chemo-preventive potential of PHC (2:1:1) and its prepared chitosan nanoparticles is evaluated upon determining liver markers, antioxidant parameters, total bilirubin, protein, lipid peroxidation, and liver cancer biomarkers.

The disclosure relates to therapeutic proteins and pharmaceutical compositions comprising said proteins, which have utility in treating various human diseases. In particular aspects, the disclosed therapeutic proteins are useful for treating human gastrointestinal inflammatory diseases and gastrointestinal conditions associated with decreased epithelial cell barrier function or integrity. Further, the disclosed therapeutic proteins are useful for treating human inflammatory bowel disease, including inter alia, Crohn's disease and ulcerative colitis.
