Abstract: The present invention relates to cutting body hair such as beard stubble. More particularly, the present invention relates to a cutter system for an electric shaver and/or trimmer, with a pair of cooperating cutting elements with at least one row of comb-like cutting teeth. The cutting elements are movably supported relative to each other by a support structure. At least one of the cutting elements, when viewed in cross section, has a C-shape including a pair of dog-eared holding flanges attached to the support structure and a slightly dome shaped or flat center section. The row of comb-like cutting teeth are formed in a transitional section between the dog-eared holding flanges and the center section. The dog-eared holding flange at the transitional section may be provided with a step-like concave depression forming thinned-out tooth tips.

Abstract: The present invention discloses a genetically engineered bacteria, which is E. coli integrated with lysogenic ?DE3, and lacZ gene is completely inactivated, but does not affect exogenous protein expression of the genetically engineered bacteria. The present invention also discloses a method for culturing the genetically engineered bacteria, and a method for preparing human milk oligosaccharides using the same, and use of the genetically engineered bacteria. The genetically engineered bacteria of the present invention can efficiently produce human milk oligosaccharides, such as 2?-fucosyllactose, and have wide industrial application prospects.

Abstract: The invention discloses a genetically engineered bacterium and a method for preparing a fucosylated oligosaccharide using the same. The method includes: transferring a fucosyl group of a donor to an oligosaccharide receptor by a fucosyltransferase heterologously expressed in a genetically engineered bacterium; wherein the donor is a nucleotide-activated donor, the fucosyltransferase has ?-1,2-fucosyltransferase activity; wherein, the fucosyltransferase is selected from one or more of the enzymes corresponding to NCBI Accession Numbers WP_109047124.1, RTL12957.1, MBP7103497.1, WP_120175093.1, RYE22506.1, WP_140393075.1 and HJB91111.1. The preparation method of the invention has high yield, greatly improved substrate conversion rate and product conversion rate, and has the potential to be applied to industrial production.

Abstract: The present invention relates to the field of biomedicine, and in particular to a use of goji glycopeptide in the preparation of a drug for preventing and/or treating amyotrophic lateral sclerosis. Experimental results prove the use of goji glycopeptide in the preparation of a drug for preventing and/or treating amyotrophic lateral sclerosis.

Abstract: The present invention relates to an electric hair removal device, in particular an electric shaver or a hair trimmer or a hair epilator, comprising a handle and a head, said head comprising a head base, a first attachment for skin treatment, said first attachment being releasably connectable with said head base, and a second attachment having a hair removal tool, said first attachment being releasably connectable with said head base, wherein a motor output drive is moveable and non-operatively coupled within an inner head space of a joint head housing of said head base and said first attachment for generating head housing vibrations.

Abstract: A cutter system for an electric shaver and/or trimmer, having a pair of cooperating cutting elements with two rows of comb-like cutting teeth at opposite edges thereof and at least one field of cutting perforations between the rows of comb-like cutting teeth. The cutting elements are movably supported relative to each other by a support structure with an inner one of the cutting elements being sandwiched between an outer one the cutting element and the support structure. The support structure includes a pair of outer frame portions and a pair of inner frame portions supporting the inner cutting element. The inner frame portions form rigid support ribs extending from a base portion of the support structure at a steeper angle than the outer frame portions and forming rigid support edges supporting the inner cutting element along the outer edge of the field of cutting perforations.

Abstract: The present invention relates to cutting body hair such as beard stubbles of multidays' beard. More particularly, the present invention relates to a cutter system for an electric shaver and/or trimmer, comprising an inner cutting element and an outer cutting element forming a pair of cooperating cutting elements with at least one row of comb-like outer cutting teeth extending parallel to a first axis (I), wherein said cutting elements are movably supported relative to each other. Skin irritation may be reduced by the at least one row of comb-like outer cutting teeth having, at a position of 0.2 mm away from the tip, a ratio between tooth width in a direction perpendicular to said first axis (I) and width of an opening slot between two adjacent teeth between 1.0 and 2.0.

Abstract: The present invention relates to a cutter system for an electric shaver and trimmer, comprising a pair of cooperating cutting elements with two rows of comb-like cutting teeth at opposite edges thereof and cutting perforations between said rows of comb-like cutting teeth, wherein said cutting elements are movably supported relative to each other by a support structure. The cutting perforations may be arranged in two separated elongated fields of perforations which are separated from each other by an elongated unperforated center section of an outer one of said cutting elements defining a skin contact surface, and which include each at least two rows of perforations extending along the rows of comb-like cutting teeth.
