Methods, systems, and computer program products for hierarchical registration (102) between a blood vessel and tissue surface model (100) for a subject and a blood vessel and tissue surface image for the subject are disclosed. According to one method, hierarchical registration of a vascular model to a vascular image is provided. According to the method, a cascular model is mapped to a target image using a global rigid transformation to produce a global-rigid-transformed model. Piecewise rigid transformations are applied in a hierarchical manner to each vessel tree in the global-rigid-transformed model to perform a piecewise-rigid-transformed model. Piecewise deformable transformations are applied to branches in the vascular tree in the piecewise-transformed-model to produce a piecewise-deformable-transformed model.

The present invention relates to tissue engineering scaffolds (TE scaffolds) that mimic the biomechanical behavior of native blood vessels, tissue engineered blood vessels (TEBVs) derived from the TE scaffolds, and methods of making and using the TE scaffolds and TEBVs.

An ophthalmic formulation that includes nanoparticles. Each nanoparticle includes a shell which encapsulates sulfated non-anticoagulant heparin (SNACH), with or without hydrophobic anti-angiogenesis Tyrosine Kinase inhibitors. The SNACH is ionically or covalently bonded to the shell. The shell includes a polymer selected from the group consisting of poly (lactic-co-glycolic acid) (PLGA), chitosan, chitosan-alginate, and NIPAAM-APMAH-AA, wherein NIPAAM is N-isopropyl acrylamide, APMAH is N-3-aminopropylmethacrylamide hydrochloride, and AA is acrylic acid. A method for treating an eye disease of a subject includes: administering to an eye of the subject a therapeutically effective amount of the ophthalmic formulation for treating the eye disease. The eye disease involves an ocular angiogenesis-mediated disorder.

A method of vascularising a cell aggregate on a microfluidic device, microfluidic cell culture devices comprising perfusable vascular networks and kits and assays using the microfluidic cell culture devices are described. The microfluidic devices comprise one or more capillary pressure barriers allowing for formation of an extracellular matrix gel within a confined area of the network, in which cells can be cultured for different uses.

The invention discloses a loss preventing and hair strengthening nourishing solution. The nourishing solution comprises components in percentage by mass as follows: 0.0005%-0.002% of a hair follicle activation factor, 0.01%-1% of vitamins, 0.05%-5% of amino acid, 0.01%-1% of microelements, 0.01%-20% of a transdermal agent, 0.02%-10% of a conditioner and the balance of water. Meanwhile, the invention discloses a preparation method of the nourishing solution. The hair follicle activation factor is taken as the core effective component of the loss preventing and hair strengthening nourishing solution and matched with other auxiliary scalp nutrients, all the components cooperate and can balance microcirculatory system of scalp and reconstruct scalp barriers; the nourishing solution can activate resting cells, repair damaged hair follicle and rapidly stop loss and strengthen hair. Besides, the nourishing solution directly supplies hair growth nutrients through scalp hair follicle, can strengthen hair roots, activate activity of hair follicle, dredge blood vessels and promote rapid growth of hair, and has significant effects on soft hair, dry hair, splitting, no gloss, scalp itching, more dandruff, more hair oil, climacteric hair loss, alopecia areata and sebrrheic alopecia.

The invention discloses haemostatic forceps for liver and gall surgery. The haemostatic forceps comprise an upper forceps body and a lower forceps body which are connected through a rotating pin. A ring is fixedly connected to the rear end of the upper forceps body, and a ring is fixedly connected to the rear end of the lower forceps body. Transparent plastic bodies are welded to the front end and the rear end of the upper forceps body respectively, and transparent plastic bodies are welded to the front end and the rear end of the lower forceps body respectively. An LED light-emitting device is arranged in each transparent plastic body. An automatic connecting device is arranged on the lower side of the upper forceps body, and an automatic connecting device is arranged on the upper side of the lower forceps body. A chargeable thermal probe is fixedly connected to the lower portion of the front end of the upper forceps body. The brightness of the LED light-emitting devices in the transparent plastic bodies is sufficient, and heat is little; being installed in the integrated transparent plastic bodies of the upper forceps body and the lower forceps body, the LED light-emitting devices are more convenient to use; the chargeable thermal probe is simpler in structure, and can be charged when out of power, a temperature adjusting device installed in the probe can adjust the temperature of the probe according to needs, and therefore the haemostatic effect is better; meanwhile, due to electromagnetic upper and lower connecting bodies, the upper forceps body and the lower forceps body can vise blood vessels more tightly, and relieving is also convenient.

Methods for treating angiogenesis-mediated diseases are disclosed. More particularly, the present disclosure relates to methods of inhibiting ferrochelatase as an antiangiogenic therapy.
