  • Forensic DNA Typing charts the progress and development of DNA applied to criminal forensics, providing vivid demonstrations of the amazing potential of the method, not only to convict the guilty but also to exonerate the innocent. John Butler has created a text that caters to all audiences, covering the basics of DNA structure and function and describing in detail how the techniques are used. In addition, the extensive use of D.N.A. (Data, Notes, and Application) Boxes in the text enables the reader to dip in and out as he or she pleases....

  • This book contains four parts with 16 chapters. Firstly, an optimal stimulation scheme  for  ovaries,  particularly  natural  and  minimal  stimulation  of  ovaries,  has  been  discussed  in  the  first  part.  Then,  one  paper  analyzed  that  how  many  oocytes  per  retrieval will be  the best  for human IVF practice. If one stimulation scheme produces  too  many  eggs,  it  often  results  in  hyperstimulation  syndrome.

  • More discrete sequence alterations rely heavily on the use of the PCR, which allows rapid gene amplification and analysis. Moreover, PCR makes it possible to perform genetic testing and mutational analysis with small amounts of DNA extracted from leukocytes or even from single cells, buccal cells, or hair roots. Screening for point mutations can be performed by numerous methods (Table 62-9); most are based on the recognition of mismatches between nucleic acid duplexes, electrophoretic separation of single- or double-stranded DNA, or sequencing of DNA fragments amplified by PCR.

  • A novel, type 1 ribosome-inactivating protein designated charybdin was isolated from bulbs of Charybdis maritimaagg. The protein, consisting of a single polypeptide chain with a molecular mass of 29 kDa, inhibited trans-lation in rabbit reticulocytes with an IC50of 27.2 nm. Plant genomic DNA extracted from the bulb was amplified by PCR between primers based on the N-terminal and C-terminal sequence of the protein from dissolved crys-tals.

  • The naturally synchronous plasmodia of myxomycetes synthesize poly(b-L-malic acid), which carries out cell-specific functions. In Physarum polycephalum, poly(b-L-malate) [the salt form of poly(b-L-malic acid)] is highly concentrated in the nuclei, repressing DNA synthetic activity of DNA polymerases by the formation of reversible complexes. To test whether this inhibitory activity is cell-cycle-dependent, purified DNA polymerase a of P.

  • While the nature and prevalence of defensive medical practices have been widely debated, most agree that the costs are exorbitant. In fact, some estimates report that the practice of defensive medicine costs the American health care system in excess of $100 billion dollars annually, which would account for up to 12% of all health care expenditures.

  • Base excision repair (BER), a major pathway for the removal of simple lesions in DNA, requires the co-ordinated action of several repair and ancillary proteins, the impairment of which can lead to genetic instability. We here address the role of poly(ADP-ribose) polymerase-1 (PARP-1) in BER. Using anin vitro cross-linking assay, we reveal that PARP-1 is always involved in repair of a uracil-containing oligonucleotide and that it binds to the damaged DNA during the early stages of repair.

  • In routine histopathology, most tissues are fixed in formalin and embedded in paraffin for long-term preservation. DNA can be extracted from these tissues for subsequent molecular analysis by amplification methods. We describe herein a protocol for DNA preparation from paraffin-embedded tissues based on published procedures (1–3). In brief, tissue sections are placed into microfuge tubes, then deparaffinized with xylene. The xylene is removed with ethanol washes, and the tissue is treated with proteinase K to make DNA available for amplification....

  • Cell-free protein synthesis using cell extracts from Escherichia coli, wheat germ and rabbit reticulocytes has been used for over 40 years to produce small amounts of radiolabeled proteins for identification of gene products and other applications. In the E. coli system programmed with plasmid DNA, the cell extract contains or is supplemented with an RNA po-lymerase to transcribe the gene, and the mRNAs are translated by a complex mixture that contains ribo-somes and a full complement of initiation,...

  • The gene 4CL1 was isolated from Chinese red pine (Pinus massoniana Lamb) and ligated into vector pPTN289 to perform transformation vector pPTN289-4CL1. This construction was transformed into Agrobacterium tumefaciens strain C58, and then transformed into Chinaberrytree (Melia azedarach L.). The transgenic Chinaberrytree was screened on selection medium (MS + 0.5mg/l 6-BA + 1mg/l vitamine B5 + 30g/l sucrose + 8g/l agar + 500mg/l Cefotaxime + 1mg/l PPT) and then extracted total DNA and tested the existence of interested gene using PCR method. ...

  • This experiment examines a human Alu dimorphism at the PV92 locus. A sample of human cells is obtained by saline mouthwash (alternatively DNA may be isolated from hair sheaths). DNA is extracted by boiling with Chelex® resin, which binds contaminating metal ions. Polymerase chain reaction (PCR) is then used to amplify a chromosome region that contains the PV92 Alu dimorphism. The Alu insertion allele (+) is 300 nucleotides longer than the non-insertion allele (–), so the two alleles are readily separated by agarose gel electrophoresis.
