A Systematic Review of Kissing as a Risk Factor for Oropharyngeal Gonorrhea or Chlamydia.

Background: Tongue kissing is a poorly studied risk factor for sexually transmitted infections (STIs). We undertook the first systematic review to assess whether kissing is a risk factor for gonorrhea or chlamydia of the oropharynx.

Methods: Online databases (MEDLINE, EMBASE, CINAHL, Web of Science, Cochrane) and reference lists were searched until September 30, 2022.

Age, ethnic and travel-related disparities in kissing and sexual practices among heterosexual men in Melbourne, Australia.

Unlabelled: Background The kissing practices of heterosexual men are not well understood, despite the potential of kissing to be a significant risk factor for gonorrhoea transmission. This study aimed to explore kissing and sex practices among heterosexual men.

Methods: A cross-sectional survey among heterosexual men attending the Melbourne Sexual Health Centre in 2016-2017 was conducted.

PrP (prion) gene expression in sheep may be modulated by alternative polyadenylation of its messenger RNA.

Scrapie-associated fibrils and their major protein component, PrP or prion protein, accumulate in the brains and some other tissues of all species affected by transmissible spongiform encephalopathies or prion diseases. To investigate the role of PrP gene expression in the hosts of these diseases, we have analysed some characteristics of PrP gene RNA transcripts in sheep and cattle tissues and made comparisons with PrP RNA transcripts in human and mouse tissues. Two PrP messenger RNAs of 4.

Lymphoproliferative responses to human papillomaviruses in patients with cutaneous warts.

In vitro lymphoproliferative responses of peripheral blood mononuclear cells (PBMC) from patients with cutaneous warts, caused by infection with human papillomavirus type 1 (HPV-1) or type 2 (HPV-2), were assayed during the course of treatment. Purified HPV-1 and HPV-2 were used as antigens, as well as herpes simplex virus (HSV) and concanavalin A (Con A). All patients had normal percentages of subsets within the PBMC population and normal lymphoproliferative responses to Con A, and those with a clinical history of HSV infections had positive lymphoproliferative responses to HSV.

Detection of human apolipoprotein E3, E2, and E4 genotypes by an allele-specific oligonucleotide-primed polymerase chain reaction assay: development and validation.

A polymerase chain reaction (PCR) assay has been developed and validated by using allele-specific oligonucleotide (ASO) primers to specifically amplify E3, E2, and E4 polymorphic sequences of the human apolipoprotein E (apo E) genes. Degenerate ASOs containing one or two additional 3' mismatches provided greater specificity than did ASOs containing a single mid-sequence or 3' allele-specific mismatch with plasmid pEB4 or genomic DNA as template. Optimal specificity and efficiency of amplification did not correlate with primer annealing conditions, whether determined theoretically or via oligo-melting experiments.

Radiolabeling with organomercury compounds: Part 2. High specific activity synthesis of iodine-125 and iodine-131-6-iodocholest-5-en-3 beta-ol and its tissue distribution in rats.

Iodine-125 (125I) and iodine-131- (131I) 6-iodocholest-5-en-3 beta-ol has been prepared directly from 6-chloromercuricholest-5-en-3 beta-ol and [125I] or [131I]sodium iodide. This method produces material of "no-carrier-added" specific activity and excellent radiochemical purity. The entire procedure is complete in 10 min and can be carried out in 95% ethanol.
