摘要:
A flow-cell device for the monitoring of blood or any other cell suspension under flow comprising: a rigid transparent base having a pair of holes with inlets and outlets, one hole for transferring the cell suspension from a supplying means to a flow channel and the other hole for transferring the tested suspension back from the flow channel to a receiving means, a flow-channel plate sandwiched between the base and a transparent plate wherein the flow channel is a wide opening in the middle of the flow-channel plate, said flow-channel plate can be an integral part of either the base or the transparent plate, a transparent plate covering the flow-channel plate, a rigid cover covering the transparent plate with a hole enabling a microscope objective to approach the flow-channel plate, the transparent plate and the cover being attached to each other firmly by any conventional means or the transparent plate being an integral part of the cover.
摘要:
A medical drain tube for the removal of blood, secretions and other fluids or semifluids from surgical and inflammatory lesions and from other anatomical spaces wherein said drain is characterized by the ability to prevent or minimize an uncontrolled spillage and leakage of said fluids from the drain tube in the course of removing the drain from the patient's body at atmospheric pressure by means of unidirectional inlets along the tube's wall and a unidirectional valve or a plug at the distal opening of the drain tube, enabling the body fluids to flow in one direction from the outside into the inside of the tube.

摘要:
A system for option commodity recommendation. The system includes a network interface, a processing unit, and an option trade unit. The processing unit selects a plurality of candidate option commodities from the option trade unit according to the investment direction and the predicted stock trend received via the network interface, and calculates a possible return for each candidate option commodity under a win probability. The processing unit selects the candidate option commodity with the highest return as a recommendation option commodity under the win probability.
摘要:
The invention relates to a multifunctional vitamin D derivative of formula (I) wherein; O represents the oxygen atom of an ether group; X represents a spacer group having a length of 0.8 to 4.2 nm, for example, an amino carboxylic acid radical, an amino undecanoic acid radical, or an amino polyether radical; Y represents hydrogen or hydroxy; A represents a tracer group such as biotin, digoxygenin or another vitamin D group which are bound by a protein having a higher affinity; R represents a hydrocarbon side-group of vitamin D or vitamin D metabolites. The invention also relates to a method for quantitatively determining a 25-hydroxy-vitamin D metabolite and a 1 alpha ,25-dihydroxy-vitamin D metabolite in a sample.
摘要:
A ballpoint (10) pen has an ink reservoir tube (12) which stores ink (13), a point assembly (14) disposed in the front of the ink reservoir tube (12), and a ball bearing (16) held at the front end of the point assembly (14). The ball bearing (16) is a shape memory alloy (SMA), Preferably a TiNi intermetallic compound or a TiNi based alloy. The ball bearing (16) solves the problem of ink failing to flow when the ballpoint pen (10) is dropped on the ground.
摘要:
A method for screening an antagonist of the human endothelin receptor so as to identify and study agents of the circulatory system, comprising the steps of contacting a sample comprising a protein receptor with a candidate compound, the protein receptor having high affinity for human ET-1 and ET-2 and lower affinity for human ET-3 and an amino acid sequence from Asp at +1 to Asn at + 407 as shown in SEQ ID NO: 1, and detecting the binding of the candidate compound to the protein receptor. The agent of the circulatory system can used in the manufacture of medicament for treatment of essential hypertension, vasospastic stenocardia, acute myocardial infarction, chronic renal insufficiency, subarachnoid hemorrhage and hypoxia.
