Cell-free DNA as a potential diagnostic biomarker in academic stress: A case-control study in young adults.

Background: Stress is a pervasive issue in modern life, affecting both physical and mental health. Identifying biomarkers like cell-free DNA (cfDNA) could provide insights into stress response and help detect individuals at risk for stress-related disorders.

Objective: The aim of this study is to investigate the potential use of cfDNA as a diagnostic biomarker in individuals experiencing stress.

In silico analysis of the Val66Met mutation in BDNF protein: implications for psychological stress.

The brain-derived neurotrophic factor (BDNF) involves stress regulation and psychiatric disorders. The Val66Met polymorphism in the BDNF gene has been linked to altered protein function and susceptibility to stress-related conditions. This in silico analysis aimed to predict and analyze the consequences of the Val66Met mutation in the BDNF gene of stressed individuals.

Natural compound targeting BDNF V66M variant: insights from in silico docking and molecular analysis.

Brain-Derived Neurotrophic Factor (BDNF) is a neurotrophin gene family gene that encodes proteins vital for the growth, maintenance, and survival of neurons in the nervous system. The study aimed to screen natural compounds against BDNF variant (V66M), which affects memory, cognition, and mood regulation. BDNF variant (V66M) as a target structure was selected, and Vitamin D, Curcumin, Vitamin C, and Quercetin as ligands structures were taken from PubChem database.

Anthropological analyses of 30 insertion/deletion autosomal markers in five major ethnic groups of Pakistan.

We investigated the forensic efficacy of the 30 insertion/deletion (Indel) markers included in the Qiagen Investigator® DIPplex kit in 529 Pakistani individuals from five major subpopulations in Pakistan (Punjabi, Pashtun, Sindhi, Saraiki, and Baloch). In the Sindhi population, the distribution of HLD81 and HLD97 alleles deviated from Hardy-Weinberg equilibrium after Bonferroni correction. The combined match probability ranged from 2.

Analysis of Skin Pigmentation and Genetic Ancestry in Three Subpopulations from Pakistan: Punjabi, Pashtun, and Baloch.

Skin pigmentation is one of the most prominent and variable phenotypes in humans. We compared the alleles of 163 SNPs and indels from the Human Pigmentation (HuPi) AmpliSeq™ Custom panel, and biogeographic ancestry with the quantitative skin pigmentation levels on the upper arm, lower arm, and forehead of 299 Pakistani individuals from three subpopulations: Baloch, Pashtun, and Punjabi. The biogeographic ancestry of each individual was estimated using the Precision ID Ancestry Panel.

Forensic application and genetic diversity of 21 autosomal STR loci in five major population groups of Pakistan.

Objectives: Investigation of genetic diversity of the 21 autosomal STR loci included in the GlobalFilerTM PCR Amplification Kit in 529 Pakistani individuals belonging to the Punjabi, Pashtun, Sindhi, Saraiki, and Baloch ethnic groups. Population genetic parameters and forensic informative metrics for each group were evaluated.

Results: SE33 showed the greatest power of discrimination in all populations studied.

Development of new PCR multiplex system by the simultaneous detection of 10 miniSTRs, SE33, Penta E, Penta D, and four Y-STRs.

The 18 loci multiplex system has been instigated for co-amplification and fluorescent detection of Amelogenin and 17 STRs, including 10 MiniSTRs (CSF1PO, D18S51, D7S820, D2S1338, TPOX, D13S317, FGA, D5S818, D21S11, D16S539), SE33, Penta E, Penta D, and four Y-STRs (DYS385a/b, DYS438, DYS392). This multiplex system was developed for the simultaneous analysis of compromised DNA samples, Y-amelogenin marker mutation, motherless paternity issues where single allele sharing occurs at autosomal STRs in unrelated individuals, and other complex forensic cases. Selection of loci, primers, and allelic ladders were designed and created in-house with a design strategy to work in this multiplex.

Genetic distribution of 15 autosomal STR markers in the Punjabi population of Pakistan.

Genetic diversity of 15 autosomal short tandem repeat (STR) loci was evaluated in 713 unrelated individual samples of a Punjabi population of Pakistan. These loci were scrutinized to establish allelic frequencies and statistical parameters of forensic and paternity interests. A total of 165 alleles were observed with the corresponding allele frequencies ranging from 0.

Genetic polymorphism of ten MiniSTR loci in the population of Punjab Pakistan for forensic application.

Ten MiniSTR loci were analyzed on 250 unrelated individuals of Punjabi population from Punjab province of Pakistan. The product amplification range is from 65 to 280 bp. Allele frequency for a total of 98 observed alleles is from 0.
