pulmonis (Teachman et al., 2002). These results underscore the important consideration that past studies have inferred the essentiality of a mycoplasmal gene based on the use of elements that transpose actively in the genome and thus have overestimated the minimal gene set. The use of minitransposons that are stable once inserted into the genome provide a more accurate appraisal of gene essentiality. This work was supported by NIH grant AI63909. Table S1.

“The metabolic syndrome Bafetinib molecular weight (MS) is a common and complex disorder combining obesity, dyslipidaemia, hypertension and insulin resistance. It is a primary risk factor for diabetes and cardiovascular disease, and in the HIV-positive population it is increasingly considered as an emerging risk factor. The recently published guidelines from the European AIDS Clinical Society recommend measurement of waist circumference (WC) in clinical practice learn more at initial and subsequent visits in HIV-infected patients [1]. WC is considered an essential component of the definition of MS, because central obesity is more strongly correlated with other features of MS and with

insulin resistance than any other parameter [2]. Thus, a measure of abdominal obesity appears to be required to define MS, and studies

on MS should include WC measurement. However, as WC was not measured in several epidemiological Aurora Kinase studies carried out in the HIV-infected population, the use of body mass index (BMI) as a surrogate measure for WC has been advocated in the general population as well as in HIV-infected subjects, based on the assumption that BMI and WC have a strong direct relationship. In the D:A:D study [3], a cut-off of >30 kg/m2 for BMI was considered to be equivalent to a WC of 102 cm in men and 88 cm in women, which represent the cut-offs for defining MS. However, HIV-infected subjects with normal or minimally increased BMI values may well have increased visceral adiposity. In two multicentre Italian studies on MS in HIV-infected patients, the SIMONE [4] and the HERMES studies [5], we collected WC, weight and height measurements in people infected with HIV. Using these two databases, we evaluated the relationship between BMI and WC, and the BMI values corresponding to a WC of 102 cm in men and 88 cm in women. We aimed to obtain a specific equation which would be more appropriate for predicting WC from BMI for HIV-infected patients. The two databases included 1522 patients (mean age 42±9 years; 72% men; 69% on antiretroviral treatment). We performed a regression analysis of WC on BMI, separately in the two genders (Fig. 1).
