The case of the monozygotic (MZ) twin as a suspect demonstrates a practical problem in forensic casework. As the MZ twins are genetically identical, they share the same short tandem repeat (STR) profile. Many studies showed that older MZ twins have significant differences in overall content and genomic distribution of methylation between them.

- The study explores the green synthesis of metal/metal oxide nanoparticles using the methanol extract of the medicinal plant Deverra tortuosa, aiming for a safe and cost-effective approach.
- Characterization of the nanoparticles was performed using various techniques, revealing sizes between 11.79-85.9 nm and notable chemical components via GC-MS analysis, including major compounds such as methyl oleate.
- The research demonstrated significant antioxidant and antimicrobial activities of both the D. tortuosa extract and the synthesized nanoparticles, with further cytotoxic assessments against normal and tumor cell lines using MTT assays.
Background: Pure germinomas account for 40% of pineal tumors and are characterized by the lack of appreciable tumor markers, thus requiring a tumor biopsy for diagnosis. MicroRNAs (miRNA) have emerged as potential non-invasive biomarkers for germ cell tumors and may facilitate the non-invasive diagnosis of pure pineal germinomas.
Material And Methods: A retrospective chart review was performed on all patients treated at the Children's Cancer Hospital Egypt diagnosed with a pineal region tumor between June 2013 and March 2021 for whom a research blood sample was available.
Objective: Equine herpes viruses (EHVs) are considered one of the most important respiratory pathogens in equids, resulting in serious outcomes for equine health worldwide. The objectives of the current research were the detection, molecular characterization, and isolation of EHV-1 and EHV-4 circulating within different equine populations in Egypt, either clinically or in apparently healthy horses.
Material And Methods: A total of 120 field samples were collected, and DNA was extracted.
