The performances of commercial enzyme-linked immunosorbent assays (ELISAs) in detecting herpes simplex virus type 2 (HSV-2) antibodies have been inconsistent for African and human immunodeficiency virus (HIV)-positive populations. We compared the performances of the HerpeSelect and Kalon glycoprotein G2 ELISAs for patients with genital ulcer disease in Ghana and the Central African Republic. Se...

In this paper, we propose an algorithm to hide secret message in DNA String to increase the security during transmission of data. On preparation, we consider the behavior and characteristics of DNA sequences. In this paper, we propose a new Binary Coded DNA rules towards Data Hiding in DNA. DNA String is identified randomly where a secret message is encoded at Sender’s end. Same DNA String is u...

The production of cloned animals is an inefficient process because of early or late embryonic losses. This study focused on the DNA fragmentation that occurs during embryonic development. The occurrence of DNA fragmentation was examined in bovine embryos produced by in vitro fertilization (IVF) and somatic cell nuclear transfer (NT) using the terminal deoxynucleotidyl transferase (TdT) nick-end...

This study reports a comparative and mechanistic genotoxicity assessment of four engineered nanomaterials (ENMs) across three species, including E. coli, yeast, and human cells, with the aim to reveal the distinct potential genotoxicity mechanisms among the different nanomaterials and their association with physiochemical features. Both the conventional phenotypic alkaline comet test and the ne...

Objective. To analyze the genetic variability in two populations of the native canine breed “Uruguayan Cimarron” from different areas of the country. Materials and methods. DNA was isolated from 40 animals of the Cimarron breed. Using PCR, 11 RAPD (random amplified polymorphism of DNA) molecular markers were analyzed. Results. 14.9% of loci were polymorphic. We found an index of shared bands of...

A full-vectorial H-field formulation-based finite element approach is used to optimize a biosensor structure incorporating a horizontal slot waveguide. It is designed to detect DNA hybridization through the change of the effective index of the waveguide structure. The key parameters, such as normalized power confinement, power density, change in effective index, and sensitivity are presented by...

BACKGROUND Varicocele is associated with high levels of DNA damage in spermatozoa due to oxidative stress and elevated levels of sperm DNA fragmentation, which has been currently proposed to be an essential additional diagnostic test to be recommended for patients with clinical varicocele. The aim of this study was to evaluate the parameters of semen and the DNA fragmentation index (DFI) in pat...

For years, law enforcement personnel have compared DNA found at crime scenes with that of a convicted offender. Recently, a new technique has begun to focus on the genetic similarity of biological relatives. Now, if a crime scene sample partially matches the DNA profile of a previous offender, law enforcement can investigate and possibly arrest that person’s family members. This process is call...

The birth certificate is a document used by a person to obtain identification and licensing documents throughout their lifetime. For identity verification, the birth certificate provides limited information to support a person’s claim of identity. Authentication to the birth certificate is strictly a matter of possession. DNA profiling is becoming a commodity analysis that can be done accuratel...
