Abstract: An optical fiber connector comprising a base and a lid member constituting an element having a doubly split structure which forms a roughly rod-like shape when united, and a spring for housing the base and lid member and applying pressure for pressing them together, wherein centering grooves for positioning and centering optical fibers for adjoinment and connection are provided in at least one or between the opposing faces of the base and lid member which are put together. In a mode wherein the element is inserted into a C-shaped spring having a rod shape with a C-shaped cross section, the optical fibers which are inserted from both ends of the element are pushed to the centering groove and adjoined into connection. By inserting or withdrawing wedges into wedge insertion grooves formed between the base and the lid member, it is possible to open or close the element.

Abstract: A method useful in the diagnosis of Alzheimer's Disease in a patient in which an amyloid protein precursor (APP) substrate is combined with a sample of cerebrospinal fluid or blood obtained from the patient to be tested, and poteolytic cleavage of the APP substrate is detected. The absence of detectable proteolytic cleavage, or the detection of a substantially lesser degree of proteolytic cleavage, in the presence of the patient's sample compared to that detected when an APP substrate is combined with test samples from control individuals, indicates affliction with Alzheimer's Disease. Convenient test reagents and kits for aiding the diagnosis of Alzheimer's Disease are provided, such as comprising an APP substrate and immunoreagents for detecting a fragment formed by proteolytic cleavage as well as chromogenic APP substrates.
