Abstract: This invention is a tampon wetness detection system which includes a housing (70) having a distal end, a proximal end, the proximal end being shaped, and dimensioned for insertion into a distal end of an absorbent body (12) inserted into a vagina, and the proximal end of the housing being fluid permeable; a radio frequency identification device (16) being implemented in the housing, and the radio frequency device including a transmitter (18); a conductive wetness sensor (20) being in the proximal end of the housing, and in electrical communication with the radio frequency identification device such that when the conductive wetness sensor senses wetness the radio frequency identification device is operable; a remote reporting device including a receiver for receiving a radio signal concerning the wetness of the absorbent body from the radio frequency identification device, and further including a reporting mechanism for reporting a user of the wetness of the absorbent body.

Abstract: Methods and kits of characterizing a GC rich region of a nucleic acid of interest are provided. One method is effected by (a) contacting the nucleic acid of interest with an agent that modifies cytosine or guanine residues into residues complementary to adenine or thymine for obtaining a modified nucleic acid in which the cytosine or guanine residues are replaced by the residues complementary to adenine or thymine; (b) amplifying the modified nucleic acid by amplification primers being hybridizable with the modified nucleic acid and being designed for directing amplification of at least a portion of the modified nucleic acid, for obtaining an amplification product corresponding to the GC rich region; and (c) determining the size of the amplification product, thereby characterizing the GC rich region of the nucleic acid of interest.

Abstract: A system for diagnosis of menorrhagia, menstrual cycle disorders and their causes comprising (a) a device including (i) a menses-collecting article, e.g., insertable into a vagina; (ii) at least one sensor for sensing a presence of menses in one or more distinct locations of the menses-collecting article; and (iii) a reporter being in data communication with the at least one sensor for reporting the presence of menses in the one or more distinct locations of the menses-collecting article, the reporter serving for recording information relating to the presence of menses in the one or more distinct locations of the menses-collecting article in a time related manner; and (b) an analyzing unit for receiving the information from the reporter and for analyzing the information.

Abstract: A method of simultaneous determination of the identity of nucleotide bases at specific positions in nucleic acids of interest, which includes (a) treating a sample containing the nucleic acids of interest to obtain unpaired nucleotide bases spanning the specific positions, if the nucleic acids are not already single stranded; (b) contacting the unpaired nucleotide bases with combinations of various marked oligonucleotide primers each for hybridizing with a stretch of nucleotide bases present in each nucleic acid of interest immediately adjacent the nucleotide base to be identified, so as to form a duplex between the primer and the nucleic acid of interest such that the nucleotide base to be identified is the first unpaired base in the template immediately 5' of the nucleotide base annealed with the 3'-end of the primer in the duplex; (c) contacting the duplex with the reagent which includes an aqueous carrier, and at least one primer extension unit, the primer extension unit including an extension moiety a se

Abstract: A method aimed at the quantification of di- and trinucleotide repeat which includes (a) treating a sample containing the nucleic acids of interest to obtain unpaired nucleotide bases spanning the position of the repeats and flanking regions, if the nucleic acids are not already single stranded; (b) contacting the unpaired nucleotide bases with an oligonucleotide primer capable of hybridizing with a stretch of nucleotide bases present in the nucleic acid of interest preferably 3' of the trinucleotide repeats to be quantified, so as to form a duplex between the primer and the nucleic acid of interest; (c) providing means to ensure that the examined nucleic acid and the oligonucleotide primer are confined to a reaction chamber at all further steps; (d) contacting the duplex with a primer extension unit which is capable of base pairing with the first nucleotide base in the core sequence of the repeats, and a template dependent extension enzyme; (e) eliminating non-incorporated primer extension units; (f) contacti
