In vivo molecular evaluation of guinea pig skin incisions healing after surgical suture and laser tissue welding using Raman spectroscopy.

The healing process in guinea pig skin following surgical incisions was evaluated at the molecular level, in vivo, by the use of Raman spectroscopy. After the incisions were closed either by suturing or by laser tissue welding (LTW), differences in the respective Raman spectra were identified. The study determined that the ratio of the Raman peaks of the amide III (1247 cm(-1)) band to a peak at 1326 cm(-1) (the superposition of elastin and keratin bands) can be used to evaluate the progression of wound healing.

Lifetime sexual and physical victimization among male veterans with combat-related post-traumatic stress disorder.

Because of the high prevalence of post-traumatic stress disorder (PTSD) among veteran men and the limited research on victimization in this group, we recruited 133 male veterans with combat-related PTSD from a psychiatric inpatient unit and assessed them for lifetime physical and sexual trauma. Results indicated that 96% of the sample had experienced some form of victimization over their lifetimes; 60% reported childhood physical abuse, 41% childhood sexual abuse, 93% adulthood physical assault, and 20% adulthood sexual assault. In the preceding year alone, 46% experienced either physical or sexual assault.

Guidelines for preclerkship bioterrorism curricula.

Purpose: To develop medical school curriculum guidelines related to bioterrorism to ensure that future medical graduates are armed with the critical knowledge, skills, and attitudes to face this emerging threat.

Method: An Internet-based Delphi survey was performed in 2002 under the auspices of the Association of Medical School Microbiology and Immunology Chairs involving 64 medical educators in microbiology, immunology, and infectious diseases representing 54 U.S.

Retrospective analysis of an outbreak of B virus infection in a colony of DeBrazza's monkeys (Cercopithecus neglectus).

In 1981, an outbreak of herpetic disease developed in a colony of DeBrazza's monkeys (Cercopithecus neglectus). In seven of eight infected animals, clinical signs of infection included vesicular and ulcerative lesions on the lips, tongue, and/or palate. Histologic examination of lesions revealed intranuclear inclusion bodies, and electron microscopy revealed nucleocapsids and virions with typical herpesvirus morphology.
