Abstract: The present invention refers to a furocoumarin-rich extract for use as antimicrobial substance, drug or medicament which comprises an extract of Angelica archangelica. The invention also refers to a non-toxic Angelica plant species furocoumarin-rich extract produced by a described method and to a said method of producing the extract. The Angelica archangelica furocoumarin-rich extract produced as described has shown a marked significant in vitro cytoprotective effect in SARS-CoV-2-exposed Vero E6 cellular cultures. The non-toxic furocoumarin-rich extract may be used for treating pathogenic infections of nucleic acid-regulated microbiome including but not restricted to virus, bacteria, parasites and fungus affecting animals and human beings.

Abstract: A connection system for connecting a board 1 to a boot comprises a plate 5 which is connectable to the board 1, a button 3 having a bottom face and a top face, the top face being connectable to a boot or binding 2, and a collar 4, wherein a part of the button 3 is sandwiched between the collar 4 and the plate 5 with its bottom face adjoining the plate 5, and its top face exposed through the collar 4, such that it can rotate about an axis passing through the connection system and wherein the bottom face of the button 3 has a curved surface, which has rotational symmetry with and which adjoins a complimentary curved surface on the plate 5, such that button 3 can roll to move its axis of rotation A away from an axis P perpendicular to the plate 5, and in that the connection system comprises braking means 8, which restricts movement of the button 3.

Abstract: The invention provides a conjugate of hemoglobin and a nucleic acid cross-linking agent.

Abstract: A method of coin testing is provided in which a laser beam (13) is directed onto a face of a coin (4) and a laser detector (3) is used to detect where the laser beam is intercepted by the coin and where the laser beam is not intercepted by the coin, so as to obtain an indication of a characteristic of the face of the coin. The characteristic of the coin is used to identify the coin. The invention also relates to an apparatus for coin testing, which comprises a laser source (11) to direct a laser beam (13) on a face of a coin (4), a laser detector (3) for detecting where the laser is intercepted by the coin and where the laser is not intercepted by the coin, and a signal-processor (14) which obtains an indication, from an output of the laser detector (3), of a characteristic of the face of the coin which is used to identify the coin.
