PURPOSE: This phase I research study is looking at the presence of donor-derived DNA in semen samples form cancer survivors who underwent donor stem cell transplant.
- To examine semen samples from male survivors of allogeneic hematopoietic stem cell transplantation for the presence of donor-derived DNA.
OUTLINE: Semen samples are collected and assessed by flow cytometry and PCR. DNA samples are compared to previously analyzed DNA extracted from survivor and donor. Samples are also analyzed for sperm concentration, motility, morphology, and viability.

RATIONALE: PEG-interferon alfa-2b may interfere with the growth of tumor cells. Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It may ...
RATIONALE: Aflibercept may be able to carry cancer-killing substances directly to myelodysplastic syndrome cells. It may also stop the growth of cancer cells by blocking blood flow to the ...
RATIONALE: Studying samples of tissue and blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to c...

RATIONALE: Collecting and storing samples of tissue, blood, and bone marrow from patients with cancer to study in the laboratory may help doctors learn more about changes that may occur in...
We assessed the applicability of giant unilamellar vesicles (GUVs) for RNA detection using in vesicle reverse transcription polymerase chain reaction (RT-PCR). We prepared GUVs that encapsulated one-p...
Spectral and imaging flow cytometry are emerging technologies that allow quantifying spectral, fluorescent, and/or morphological parameters of heterogeneous cellular populations. The protocol describe...
We aim to update a meta-analysis to evaluate the efficiency of polymerase chain reaction (PCR) for diagnosis of periprosthetic joint infection (PJI) because different types of PCR assays have yielded ...
The phosphorylation of histone H2AX (γ-H2AX) at the DNA double-strand break (DSB) site is frequently used for quantifying DSBs and may be useful as a biomarker for clinical applications. We have prev...
To detect the presence of herpes virus in corneal scrapings/corneal grafts of suspected herpetic keratitis patients attending the outpatient department/casualty of the Dr Rajendra Prasad Centre for Op...
Methods for using more than one primer set in a polymerase chain reaction to amplify more than one segment of the target DNA sequence in a single reaction.
Methods used for detecting the amplified DNA products from the polymerase chain reaction as they accumulate instead of at the end of the reaction.
A heat stable DNA-DIRECTED DNA POLYMERASE from the bacteria Thermus aquaticus. It is widely used for the amplification of genes through the process of POLYMERASE CHAIN REACTION. EC 2.7.7.-.
MOLECULAR BIOLOGY techniques used in the diagnosis of disease. Included are such techniques as IN SITU HYBRIDIZATION of chromosomes for CYTOGENETIC ANALYSIS; OLIGONUCLEOTIDE ARRAY SEQUENCE ANALYSIS of gene expression patterns in disease states; identification of pathogenic organisms by analysis of species specific DNA sequences; and detection of mutations with POLYMERASE CHAIN REACTION.
In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
