Oral streptococci such as Streptococcus gordonii are facultative anaerobes that initiate biofilm formation on tooth surfaces. An isolated S. gordonii::Tn917-lac biofilm-defective mutant contained a transposon insertion in an open reading frame (ORF) encoding a homolog of NosX of Ralstonia eutropha, a putative maturation factor of nitrous oxide reductase.… (More)
Reported are various techniques to determine the early postmortem period by examining the eye. These include corneal opacity, retinal vessel segmentation, pupil reaction, retinal changes and intraocular pressure. All are subjective, requiring experience to implement the techniques.
OBJECTIVE To determine the prevalence of mutations in transforming growth factor beta 3 (TGFβ3) and Jagged2 genes and their association with nonsyndromic cleft lip with or without cleft palate (CL±P) patients. DESIGN Cross-sectional study on nonsyndromic CL±P and noncleft patients. SETTING Reconstructive clinic and outpatient dental clinic, Hospital… (More)
Two novel human leukocyte antigen (HLA) class II alleles have been identified in routine typing of bone marrow donors for the Australian Bone Marrow Donor Registry in Sydney, Australia. Sequence analysis of exon 2 of both the DQB1 and DRB1 genes revealed the novel polymorphism. A silent substitution of G to A at nucleotide position 210 has been identified… (More)
Presented in this paper are the initial results involving the use of the nose or outer ear as temperature measurement sites to determine the postmortem period of the human corpse. Simple mathematical models for both sites are developed based on cooling curves of five corpses. Analysis of errors between actual and calculated postmortem intervals suggest that… (More)
