Abstract: An optical system for a stereo video endoscope, a stereo video endoscope and a method for operating an optical system. The optical system includes a distal optical assembly and a proximal optical assembly with a left lens system channel and a right lens system channel. The distal optical assembly couples light incident from an object space into the left lens system channel and into the right lens system channel of the proximal optical assembly. The distal optical assembly is an optical assembly with an adjustable focal length, wherein a change in the focal length causes a displacement of an axis intersection point in the object space.

Abstract: An anti-oxidative Lactobacillus rhamnosus CCFM1107 can relieve chronic alcoholic liver injury, and L. rhamnosus CCFM1107 can be used in preparing dairy products as starter culture. The dairy products of this invention include milk, milk powder, milk capsules or fermented milk containing L. rhamnosus CCFM1107. It has strong abilities of anti-oxidation, scavenging diphenyl picrylhydrazyl (DPPH) radical and hydroxyl radical, inhibiting lipid peroxidation, tolerating cholate, chlorine sodium and pH, and can improve liver function and antioxidative index, lower serum endotoxin level and regulate intestinal flora distribution, thus effectively relieving alcoholic liver injury of mice.

Abstract: The invention provides a novel strain of cadmium-removing Lactobacillus plantarum bacterium, CCFM8610, which has a good tolerance to acidic environments. Lactobacillus plantarum CCFM8610 has a good tolerance to cadmium-containing medium and can effectively bind cadmium in vitro. Animal studies have shown that it can effectively reduce tissue cadmium accumulation and facilitate fecal cadmium excretion. Lactobacillus plantarum CCFM8610 has a great potential to be used as an active ingredient in cadmium-removing pharmaceutical drugs and fermented foods.

Abstract: It relates to the manufacturing and preparation of frozen dough, and its application in microwaveable fried food. The preparation of fried fritters comprises the following steps: disposal of raw materials, dough kneading, dough proofing for the first time, dough folding, dough proofing for the second time, making blanks, frying and quick-freezing. Alum as the acidic component in leavening agents is replaced by a complex formulation of gluconic acid-?-lactone, glycerol monolaurate and calcium dihydrogen phosphate, thus reducing the toxicity of the dough. The fried fritters preparing by the dough of the present invention possess a good expansion rate, crispness and taste, and should satisfy consumer demands for quality food products that can be reheated by microwaving.
