Lysine 2,3-Aminomutase and a Newly Discovered Glutamate 2,3-Aminomutase Produce β-Amino Acids Involved in Salt Tolerance in Methanogenic Archaea.

Many methanogenic archaea synthesize β-amino acids as osmolytes that allow survival in high salinity environments. Here, we investigated the radical -adenosylmethionine (SAM) aminomutases involved in the biosynthesis of N-acetyl-β-lysine and β-glutamate in C7. Lysine 2,3-aminomutase (KAM), encoded by MmarC7_0106, was overexpressed and purified from followed by biochemical characterization.

Raising lipids acutely reduces baroreflex sensitivity.

Impaired baroreflex sensitivity (BRS) is associated with hypertension and cardiovascular risk. Lipid abnormalities accompanying insulin resistance may impair BRS. To test this, nine obese, dyslipidemic hypertensive and seven healthy normotensive individuals were studied.

Training status and interest in certification of nondiplomate faculty teaching predoctoral dental public health.

Objectives: A survey was conducted to better understand the training needs of faculty members without dental public health (DPH) specialty board certification who teach DPH to dental students.

Methods: An 11-item questionnaire was sent to 193 non-DPH diplomate faculty members at US dental schools who were dentists and at least one of the following: a member of the American Association of Dental Schools Community and Preventive Dentistry Section, a referral from an academic American Board of Dental Public Health diplomate, a DPH faculty listed on the school's Web pages, a DPH contact from the AADS Institutional Directory, or the school's dean if no other contact.

Results: A 70 percent response rate was obtained.

Academic dental public health diplomates: their distribution and recommendations concerning the predoctoral dental public health faculty.

Objective: The purpose of this study was to assess the representation of academically based diplomates of the American Board of Dental Public Health (ABDPH) and to identify their perceptions on the training of dental public health predoctoral faculty.

Methods: Data were collected by a mailed, self-administered, 13-item questionnaire. The population was the 48 diplomates of the ABDPH as of March 1997 associated with academic institutions.
