Fluorescent hydrogen-bonded organic framework act as a multifunctional platform for Fe and F sensing, and for information encryption.

Due to their exceptional optical properties and adjustable functional characteristics, hydrogen-bonded organic frameworks (HOFs) demonstrate significant potential in applications such as sensing, information encryption. However, studies on the synthesis of HOFs designed to construct multifunctional platforms are scant. In this work, we report the synthesis of a new fluorescent HOF by assembling melem and isophthalic acid (IPA), designated as HOF-IPA.

Evaluation of 12 Multi-InDel markers for forensic ancestry prediction in Asian populations.

Various types of genetic markers have been applied to forensic ancestry inference. Biallelic markers, such as SNPs and InDels, have proven to be optimal choices except for the low information content provided by a single locus. Multi-InDel marker is defined as a specific DNA fragment with several InDel markers located tightly in the physical position.

Genetic portrait and phylogenetic analysis of an Aksu Uyghur population based on the 19 X-STR system.

The X chromosome has a special mode of inheritance, and is thus a rich resource for population studies. In this study, the allele frequencies and forensic statistics of the 19 X chromosomal short tandem repeat loci were evaluated in 500 Uyghur individuals from Aksu Prefecture in northwest China. We further aimed to study whether the Uyghur populations located in various regions of Xinjiang share similar allele and haplotype frequency distributions, as they have experienced genetic exchanges.

Genetic diversity and phylogenetic study of the Chinese Gelao ethnic minority via 23 Y-STR loci.

Haplotype diversity for 23 Y chromosomal short tandem repeat (Y-STR) loci included in the PowerPlex Y23 System was analyzed in the Chinese Gelao minority group of 234 unrelated males living in Daozhen Gelao-Miao Autonomous County in Guizhou Province, southwest China. A total of 216 different haplotypes were detected, of which 199 haplotypes were unique. The overall haplotype diversity (HD) and discrimination capacity (DC) were 0.

Next Generation Sequencing Plus (NGS+) with Y-chromosomal Markers for Forensic Pedigree Searches.

There is high demand for forensic pedigree searches with Y-chromosome short tandem repeat (Y-STR) profiling in large-scale crime investigations. However, when two Y-STR haplotypes have a few mismatched loci, it is difficult to determine if they are from the same male lineage because of the high mutation rate of Y-STRs. Here we design a new strategy to handle cases in which none of pedigree samples shares identical Y-STR haplotype.

Forensic characteristics and phylogenetic analyses of the Chinese Yi population via 19 X-chromosomal STR loci.

The demographic characteristics and genetic polymorphism data of 56 Chinese nationalities or 31 administrative divisions in Chinese mainland have repeatedly been the genetic research hotspots. While most genetic studies focused on some particular Chinese populations based on autosomal or Y-chromosomal genetic markers, the forensic characteristics and phylogenetic analyses of the seventh largest Chinese population (Yi ethnicity) on the X-chromosomal genetic markers are scarce. Here, allele frequencies and forensic statistical parameters for 19 X-chromosomal short tandem repeat loci (DXS7424-DXS101, DXS6789-DXS6809, DXS7423-DXS10134, DXS10103-HPRTB-DXS10101, DXS10159-DXS10162-DXS10164, DXS10148-DXS10135-DXS8378, and DXS7132-DXS10079-DXS10074-DXS10075) of 331 Chinese Yi individuals were obtained.

Validation of the Microreader™ 23sp ID system: A new STR 23-plex system for forensic application.

Microreader™ 23sp ID system is a new 23-plex STR genotyping system that amplified 21 non-CODIS STR loci (D6S477, D18S535, D19S253, D15S659, D11S2368, D20S470, D1S1656, D22-GATA198B05, D7S3048, D8S1132, D4S2366, D21S1270, D13S325, D9S925, D3S3045, D14S608, D10S1435, D12S391, D2S1338, D17S1290 and D5S2500), one CODIS STR locus (D16S539) and the amelogenin locus in one reaction. Microreader™ 23sp ID system was validated according to the guidelines of "Validation Guidelines for DNA Analysis Methods (2012)" described by the Scientific Working Group on DNA Analysis Methods (SWGDAM), including PCR-based studies, sensitivity study, precision and accuracy evaluation, stutter percentage and peak height ratio, inhibitors, species specificity and DNA mixture studies. Our results suggested that Microreader™ 23sp ID system is a useful tool for identification and parentage testing.

Population genetics of 23 Y-STR loci in the Mongolian minority population in Inner Mongolia of China.

In this study, 23 Y chromosomal STRs (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385a, DYS385b, DYS438, DYS439, DYS437, DYS448, DYS456, DYS458, DYS635, YGATAH4, DYS576, DYS481, DYS549, DYS533, DYS570, and DYS643) were investigated in 258 unrelated individuals of Mongolian descent living in the Inner Mongolia Autonomous Region. A total of 233 different haplotypes were found, and 209 of them were unique. Haplotype diversity was 0.

Phylogenetic analysis and forensic characteristics of 12 populations using 23 Y-STR loci.

Genetic analysis of Y-STRs has the potential to be used to explore the complexity in population substructures and to perform forensic ancestry inference. In this study, 334 individuals from 12 populations were typed using the PowerPlex(®) Y23 System (Promega, USA) to investigate their relationship. Population comparisons with other East Asian populations collated from YHRD (Y-STR Haplotype Reference Database) were also performed.
