Genetic dissection of five ethnic groups from Punjab, North-West India-A study based on Autosomal Markers.

The present study assessed the applicability of Alu insertion elements and Single Nucleotide Polymorphisms (SNPs) in forensic identification and estimated the extent of genetic variation in five major ethnic groups of Punjab, North-West India. A total of 1012 unrelated samples belonging to Banias, Brahmins, Jat Sikhs, Khatris and Scheduled Castes were genotyped for four Alu elements (ACE, APO, PLAT, D1) and six Single Nucleotide Polymorphisms [ESR (PvuII), LPL (PvuII), HTR2A (MspI), DRD2 Taq1A, Taq1B, Taq1D]. Allele frequencies observed heterozygosity and forensic efficacy parameters were determined.

Morphology and age-related changes in calcospherites of human teeth: an ultrastructural study.

Background: Dentine has been examined extensively for age-related physiological changes, but there are limited data on age-related changes at ultrastructural level of dentine.

Aim: The present study aimed to examine age-related ultrastructural changes in calcospherites of human dentine under the scanning electron microscope.

Materials And Methods: Thirty single rooted teeth of North Western adult Indians (18-75 years) were collected from the Department of Oral Health Sciences, PGIMER, Chandigarh.

Genetic differentiation and population structure of five ethnic groups of Punjab (North-West India).

The state of Punjab in the North-West part of India has acted as the main passage for all the major human invasions into the Indian subcontinent. It has resulted in the mixing of foreign gene pool into the local populations, which led to an extensive range of genetic diversity and has influenced the genetic structure of populations in Punjab, North-West India. The present study was conducted to examine the genetic structure, relationships, and extent of genetic differentiation in five Indo-European speaking ethnic groups of Punjab.

Analysis of ANKKI (rs1800497) and DRD2 (rs1079597, rs1800498) variants in five ethnic groups from Punjab, North-West India.

Dopamine D2 receptor (DRD2) is one of the essential neurotransmitters in the brain studied extensively in the field of psychiatric disorders, alcoholic behaviors and Pharmacology. It is also a promising gene for studying the evolutionary and genetic variation among populations. The present study was an attempt to understand the extent of genetic variation among five different ethnic groups (Bania, Brahmin, Jat Sikh, Khatri and Scheduled caste) of Punjab (North West India).

Body composition and fat distribution among older Jat females: a rural-urban comparison.

The aim of the present cross-sectional study is to describe and compare age related changes in body composition and fat patterning among rural and urban Jat females of Haryana State, India. A total of 600 females (rural=300, urban=300), ranging in age from 40 to 70 years were selected by the purposive sampling method. Body weight, height, two circumferences (waist and hip) and skinfold thickness at five different sites (biceps, triceps, calf, subscapular, and supra-iliac) were taken on each participant.

The most ancient democracy in the world is a genetic isolate: an autosomal and Y-chromosome study of the hermit village of Malana (Himachal Pradesh, India).

Malana, a small village in Kullu District of Himachal Pradesh, India, has historically been considered a hermit village. Today it has a census size of 1,101 individuals. Geographic, linguistic, and population barriers have contributed to its seclusion.

Growth trends in body, fat, circumferential and physiological traits during adolescence among Rajput females of Theog, Shimla District (Himachal Pradesh), India.

Background: Information on growth status of a population is essential to establish the health status of the population and administer any health intervention programmes.

Aims: The study aimed to examine growth patterns in body, fat and physiological traits during adolescence in the light of various hypotheses and other studies.

Subjects And Methods: Cross-sectional data on a sample of 220 Rajput girls aged 11-17 years were collected from Theog tehsil, Shimla District in Himachal Pradesh.

A grey zone approach for evaluation of 15 short tandem repeat loci in sibship analysis: a pilot study in Indian subjects.

The evaluation of 15 STR loci Applied Biosystems Identifiler kit for sibship determination in Indian subjects is reported. Cumulative sibship indices (CSIs) calculated following standard methods in sibling pairs and non-sibling pairs, showed mean values comparable to other reports. Mean CSI value in sibling group was higher than in corresponding non-sibling group.
