Abstract: The present disclosure provides compositions and methods of use for effectively treating aquarium water in long term. The compositions include various components functioning to improve water quality, reduce or remove inorganic nitrogen and phosphorus, stabilize buffer capacity, and provide other advantages to aquarium water. Methods of using the compositions to improve the efficiency of treating aquarium water are also provided. The compositions and methods of the present disclosure can improve prophylaxis against unfavorable aquatic plant such as algae and extend life of animals in aquarium water.

Abstract: The present description relates to a polymer composition for use in repairing tissue of a patient comprising at least one blood component, as polymer, such a chitosan, and at least one inorganic salt, such as NaCl, method of the composition and method of preparing the composition.

Abstract: The present disclosure relates to an activated polymer composition for use in repairing tissue of a patient comprising platelet-rich plasma (PRP), a chitosan solution, a salt such as NaCI or glycerol phosphate, and an activator such as at least one of CaCI2 and a mixture of thrombin/CaCI2.

Abstract: In some embodiments, a forming body for the temporary sealing of a flow cross-section of an assigned object to be welded is disclosed. In some embodiments, the forming body comprises a dimensionally stable, preferably biologically-degradable material, which has a water solubility ?90% and of which the main component is corn starch and/or corn semolina and/or corn flakes.

Abstract: There is described a method for non-invasively measuring electrical activity in a joint of a subject, the method comprising: removably attaching in a non-invasive manner at least two electrodes to a skin surface around an articulation comprising the joint; generating electroarthrographic potentials within the joint by loading the articulation; capturing the electroarthrographic potentials using the at least two electrodes; discriminating between electroarthrographic potentials originating from joint tissue activity and those from other sources; and generating measurement signals representing the electrical activity of joint tissue.

Abstract: The present invention provides compositions and methods for tissue repair using a cytocompatible self-gelling cross-linked hydrogel. The composition comprises a biocompatible mixture of chitosan, bifunctional dialdehyde, and hydroxylated polymer, which can be used to immobilize or encapsulate viable cells, or bioactive substances. The method includes the process of mixing bioactive substances, live cells, and/or extracellular matrix components with a cross-linking solution comprising a bifunctional aldehyde-treated hydroxylated polymer such as hydroxyethyl cellulose. The cross-linking solution is then mixed homogenously with a neutral isotonic chitosan solution. The chitosan becomes cross-linked by the bifunctional aldehyde, while the cells are protected from potentially nocive effects of the aldehyde cross-linker by the hydroxylated polymer. The injectable solution retains cell viability and bioactivity, and immobilizes cells at the site of injection or delivery.

Abstract: The present invention relates to a new method for repairing human or animal tissues such as cartilage, meniscus, ligament, tendon, bone, skin, cornea, periodontal tissues, abscesses, resected tumors, and ulcers. The method comprises the step of introducing into the tissue a temperature-dependent polymer gel composition such that the composition adhere to the tissue and promote support for cell proliferation for repairing the tissue. Other than a polymer, the composition preferably comprises a blood component such as whole blood, processed blood, venous blood, arterial blood, blood from bone, blood from bone-marrow, bone marrow, umbilical cord blood, placenta blood, erythrocytes, leukocytes, monocytes, platelets, fibrinogen, thrombin and platelet rich plasma. The present invention also relates to a new composition to be used with the method of the present invention.

Abstract: A method for signaling an escape route in a building with emergency warning units arranged in a distributed way can be realized such that the emergency warning units are equipped with luminous means that in the event of an emergency can be activated by a central emergency warning system sequentially in the manner of a running light that designates the direction of the escape route leading away from a hazard site. An emergency warning unit suitable for this purpose may include two LEDs configured as arrows facing in opposite directions, of which either can be switched into a blinking mode by the central emergency warning system in accordance with the emergency conditions.
