Genetic markers are powerful tools for understanding genetic diversity and the molecular basis of traits, ushering in a new era of molecular breeding in crops. Over the past 50 years, DNA markers have rapidly changed, moving from hybridization-based and second-generation-based to sequence-based markers. Simple sequence repeats (SSRs) are the ideal markers in plant breeding, and they have numerous desirable properties, including their repeatability, codominance, multi-allelic nature, and locus specificity.

Single nucleotide polymorphism (SNP)-based markers are increasingly gaining momentum for screening and utilizing vital agronomic traits in wheat. To date, more than 260 million SNPs have been detected in modern cultivars and landraces of wheat.

Then it was characterized by assaying the optimal pH, temperature, storage stability and reusability. The results on immobilization with sodium alginate and calcium chloride showed that a combination of 2% sodium alginate and 0.

Children presenting with recurrent infections have a high risk of developing vitamin A deficiency. Conjunctival impression cytology (CIC) was used in the present study in such children to detect subclinical deficiency and to monitor the outcome after therapy. Seventy children with history of recurrent infections, and 10 healthy children in the age group of six months to five years were included in the study.

Introduction: Immune response plays an important role in the interaction between malignant neoplasms and their host, which is reflected as histologic changes in the lymph nodes draining tumours.
Material: 641 regional lymph nodes from 64 primary carcinomas of breast, stomach and colon were examined to assess such a response.
Methods: The lymphnodes were classified into one of the following histological patterns--lymphocyte predominance (LP), germinal centre predominance (GCP), lymphocyte depletion (LD) and unstimulated (U).
