Vaginal discharge among the primary school students and detection of the affection factors

Large gravitational wave interferometric detectors, like Virgo and LIGO, demonstrated the capability to reach their design sensitivity, but to transform these machines into an effective observational instrument for gravitational wave astronomy a large improvement in sensitivity is required. Advanced detectors in the near future and third-generation observatories in more than one decade will open the possibility to perform gravitational wave astronomical observations from the Earth. An overview of the possible science reaches and the technological progress needed to realize a third-generation observatory are discussed in this paper. The status of the project Einstein Telescope (ET), a design study of a third-generation gravitational wave observatory, will be reported

Toward Male Individualization with Rapidly Mutating Y-Chromosomal Short Tandem Repeats

Relevant for various areas of human genetics, Y-chromosomal short tandem repeats (Y-STRs) are com- monly used for testing close paternal relationships among individuals and populations, and for male lineage iden- tification. However, even the widely used 17-loci Yfiler set cannot resolve individuals and populations completely. Here, 52 centers generated quality-controlled data of 13 rapidly mutating (RM) Y-STRs in 14,644 related and unrelated males from 111 worldwide populations. Strik- ingly, >99% of the 12,272 unrelated males were com- pletely individualized. Haplotype diversity was extremely high (global: 0.9999985, regional: 0.99836\u20130.9999988). Haplotype sharing between populations was almost ab- sent except for six (0.05%) of the 12,156 haplotypes. Haplotype sharing within populations was generally rare (0.8% nonunique haplotypes), significantly lower in ur- ban (0.9%) than rural (2.1%) and highest in endogamous groups (14.3%). Analysis of molecular variance revealed 99.98% of variation within populations, 0.018% among populations within groups, and 0.002% among groups. Of the 2,372 newly and 156 previously typed male relative pairs,29% were differentiated including 27% of the 2,378 father\u2013son pairs. Relative to Yfiler, haplotype diversity was increased in 86% of the populations tested and over- all male relative differentiation was raised by 23.5%. Our study demonstrates the value of RM Y-STRs in identifying and separating unrelated and related males and provides a reference database
