Nine of 18 subjects from South-East Asia (mainly from the Philippines, Thailand and India) harboured non-B subtypes (six CRF01_AE and three C). The recombination analysis of 39 URFs identified 13 B/F, six G/A, four D/B, three A/K,

three G/A/K, three C/B, two CRF02_AG/CRF09_cpx, one CRF02_AG/B, PD0325901 one CRF06_cpx/CRF02_AG, one CRF18_cpx/B, one F/C/B and one G/CRF09_cpx recombinant. The proportion of URFs was comparable in Africans (6.8%), Europeans (9.3%) and Latin Americans (7.1%) infected with non-B clades. As expected, URFs were detected in African subjects from Cameroon, Democratic Republic of Congo, Senegal, Nigeria and Ivory Coast. All B/F recombinants were identified in Italian (n=8) or Brazilian (n=5) patients. A complex G/U/F1/B pattern, obtained from a Cuban patient, was found to be a CRF18_cpx/B recombinant, consistent with the patient’s country of origin. The CRF06_cpx/CRF02_AG unique recombinant was related

to the isolate 00NE-36 from Niger, which has been proposed as the reference sequence for CRF30_cpx (http://www.hiv.lanl.gov/content/sequence/HIV/CRFs/CRFs.html). One of two CRF02_AG/CRF09_cpx mosaic forms was harboured by a patient born in Ivory Coast, where this second-generation recombinant has been isolated. Interestingly, two groups of three sequences each were highly homologous to the MAL (A/K) [23] and the 99GR303 (G/A/K) [24] isolates, respectively. A hallmark of the HIV-1 epidemic in Europe is the substantial increase in non-B clade penetration and circulation that has taken place as a result of the migration flows from sub-Saharan Antidiabetic Compound Library solubility dmso Africa, South-East Asia

and Central and South America that have occurred since the early 1990s [6–13]. In addition to migration, travel to areas with high prevalences of HIV-1 infection, in particular those where commercial sex is widely available, is thought to be responsible for the entry of various group M subtypes into previously subtype B-restricted countries. Italian data from the Centro Operativo AIDS, based on new HIV diagnoses, indicate that the percentage of foreign patients (41.2% from Africa, 25.2% from Latin America and 16.1% from Europe) DOK2 increased from 11 to 32% from 1992 to 2007, with heterosexual contact being the most frequent route of infection (increasing from 24.6 to 75.9% in the same period). Overall, among patients newly diagnosed with HIV-1 infection in the period from 1985 to 2007, the proportion of IDUs declined from 69 to 8.6%, while sexual transmission increased from 13.3 to 73.7% and the male to female ratio decreased from 3.5 to 2.5 [18]. The distributions of ethnicity and route of infection in our patient population are in agreement with these data. Moreover, we were able to investigate the relative proportions of heterosexuals and MSM in a large seroprevalence case file mainly covering the central part of Italy. We found that <3% of HIV-1-infected patients harboured non-B clades before 1993, as compared with about 20% in subsequent years.

, 2009). Based on these data, we evaluated how heme A is synthesized by T. cruzi (and the other trypanosomatids). The coding sequences for putative proteins homologous to HOS and HAS have been identified in the T. cruzi genome. One cds, Tc00.1047053511211.70, was identified as a HAS homologue (named TcCOX15 and TcCox15 for the corresponding protein). Two cds were associated with HOS (Tc00.1047053509601.59 and Tc00.1047053509767.59)

presenting a sequence identity of 98% (named TcCOX10A and TcCOX10B, and TcCox10 A and B for the corresponding protein sequences). The predicted protein sequences [TcCox10 (A and B) and TcCox15] show about 52% and 56% homology and 37% and 41% identity to their S. cerevisiae orthologues, and they are also conserved in other trypanosomatids Pexidartinib mouse (Fig. 1). The multiple sequence alignment of HOSs includes the available trypanosomatid putative protoheme IX farnesyltransferase (HOS) and the S. cerevisiae Cox10 protein (Fig. 1a). The residues N196, R212, R216 and H317 (S. cerevisiae numbering), which are involved in the protein’s function (Bestwick et al., 2010), are conserved in trypanosomatid sequences (indicated in Fig. 1a). The multiple sequence alignment of HAS proteins includes the available trypanosomatid putative HAS enzymes and the S. cerevisiae Cox15

protein (Fig. 1b). The alignment shows that residues involved in HAS activity based on studies from selleck chemical the Bacillus subtilis CtaA enzyme are also conserved in trypanosomatid sequences (Barros et al., 2001; Hederstedt et al., 2005). also Figure 1b shows the residues

H169, H245 and H393 from S. cerevisiae numbering, which correspond to CtaA H60, H123 and H216, respectively. Both T. cruzi putative proteins present eight predicted TMs, which is compatible with this type of protein (Fig. 1). The cds for TcCOX10 and TcCOX15 were amplified by PCR using total genomic DNA as the template and introducing a 3′-coding sequence for a 6xHis tag. As TcCOX10 A and B cds show 98% identity, the primers designed recognize both of them equally. The amplified product for TcCOX10 coincided with the Tc00.1047053509601.59 (TcCOX10A) sequence, and is named TcCOX10 and TcCox10 hereafter for the corresponding protein. Both cds (TcCOX10 and TcCOX15) were subcloned into yeast expression vectors and used to transform yeast cells lacking the corresponding genes (Δcox10 and Δcox15). These knockout cells present a respiration-deficient phenotype due to the absence of heme A production and consequently a functionally inactive CcO complex (Nobrega et al., 1990; Glerum et al., 1997). This deficiency impairs the growth in a nonfermentable carbon source such as glycerol–ethanol, but they all can grow in a media containing a fermentable carbon source as glucose. Their respiratory function was restored once TcCOX10A.6xHIS or TcCOX15.6xHIS was expressed in Δcox10 or Δcox15, respectively (Fig. 2a). Both mutants were also transformed with plasmids containing the corresponding S.

This is in accordance with previous investigations that have examined supernatants from bacterial strains found in the respiratory and gastrointestinal tracts, which identified P. aeruginosa supernatant to have inhibitory properties against A. fumigatus (Yadav et al., 2005). The main antimycotic agent was shown to be pyocyanin and 1-hydroxyphenazine, which Selleck Trametinib are controlled by multiple quorum-sensing systems (Kerr et al., 1999). These networks of genes may play an important role in controlling the interactions between P. aeruginosa with A. fumigatus. It was reported that both HSL molecules and lipopolysaccharides

influence C. albicans morphology and biofilm formation, and that signalling between these two CF pathogens is bidirectional, with farnesol inhibiting the swarming ability of P. aeruginosa (McAlester et al., 2008; Bandara et al., 2010a). Further work is required to determine whether bidirectional chemical interactions exist between P. aeruginosa and A. fumigatus, as no quorum-sensing molecule has been identified as yet for A. fumigatus. This is indeed likely as autoregulatory molecules

have been identified from a range of fungal pathogens, including C. albicans (farnesol and tyrosol), Saccharomyces cerevisiae (tryptophol and phenylethylalcohol), Cryptococcus neoformans (11-mer) and Penicillium paneum (octen-3-ol) (Hornby et al., 2001; Chen et al., 2004; Chitarra et al., 2004; Alem et al., 2006; Lee et al., 2007). The interaction between P. aeruginosa Protein Tyrosine Kinase inhibitor with fungi has been reported, with C. albicans exposure to P. aeruginosa quorum-sensing molecules inhibiting filamentation (Hogan & Kolter, 2002; Hogan et al., 2004; Shirtliff et al., 2009; Holcombe et al., 2010). Our study reported that the deletion of the principal quorum-sensing

networks of P. aeruginosa (LasIR) significantly reduced the capacity for A. fumigatus to form hyphae and undergo biofilm development. Given that a similar inhibitory effect was observed Flavopiridol (Alvocidib) both through direct and through indirect interaction suggested that the release of small heat-stable molecule was responsible for the inhibition, which was confirmed as both filtered and heat-killed supernatants also elicited a biological effect. However, similar inhibition profiles were observed for both LasI and LasR, the former of which is unable to synthesize HSL. These data indicate that molecules, other than or in addition to, HSLs may play a role in modulating A. fumigatus filamentation. Hogan et al. (2004) demonstrated that 3OC12-HSL inhibited the dimorphic switching of C. albicans at a range of concentrations, whereas the smaller molecule C4-HSL had no effect on C. albicans (Hogan et al., 2004). The authors tested 10 different structurally related compounds to assess their ability to inhibit the filamentation of C. albicans, of which four (3OC12-HSL, C12-HSL, dodecanol and farnesol) inhibited the dimorphic switching of C. albicans.

, 2009). Thus, the question of arsenite binding is of great interest to synthetic biologists involved in engineering of novel molecular entities that could be used in arsenite detection and decontamination. Most of the molecular models of arsenite binding involve thiol-based chemistry. In fact, most of the proteins that have been identified to bind to arsenite and thus have been inactivated by it do so through Cys residues (Hughes,

2002; Kitchin & Wallace, 2004). However, neither Cys residue nor Tyr residues, which have also been reported to bind arsenite in some proteins (Page & Wilson, 1985), are present within the sensory domain of AroS. Perhaps the difference in the mode of binding arsenite is not too surprising when considering the function that AroS performs. This protein needs to be able to bind arsenite reversibly and to Ion Channel Ligand Library manufacturer be able to respond to changes in arsenite concentrations. Presently, we cannot provide Nutlin-3a ic50 a definitive answer of what the mechanism of arsenite sensing is; however, our work provides a foundation for further structural and mechanistic analysis of this regulatory system. In addition, not only do arsenite-oxidizing

bacteria need to be able to sense the presence of arsenite in the environment, but they also need means of evading arsenite toxicity. Our studies have demonstrated for the first time that a mutation in aroS has an effect on the growth of NT-26 in the presence of arsenite. Thus, AroS may play an additional role in the regulation of a pathway involved in tolerance to arsenite. T.H.O. is supported by a Natural Environment Research Council studentship (14404A).

“In this issue, Tordato et al. [1] present interesting findings from the Italian Cohort of Antiretrovial Naive patients (ICONA) study group considering the estimated glomerular Astemizole filtration rate (eGFR) and risk factors for mild renal dysfunction, defined as eGFR<90 mL/min/1.73 m2. Since the introduction of combination antiretroviral therapy and subsequent dramatic improvements in morbidity and mortality [2], patients with HIV infection live longer and research has increasingly been carried out on comorbidities, including renal disease [3]. There have been a number of recent studies focusing on renal function using different definitions and methodologies which can lead to conflicting results and difficulty in interpreting data. GFR is commonly estimated using the Cockcroft–Gault (CG) formula [4], the Modified Diet in Renal Disease (MDRD) equations [5], and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation [6].

This DNA fragment was cloned as a BamHI/NdeI restriction selleck chemical fragment in the expression vector pET3a (Novagen) and the clones were verified by DNA sequencing. Escherichia coli BL21(DE3)pLys was transformed with the resulting construct. Following isopropyl β-d-1-thiogalactopyranoside (IPTG) induction (100 μM IPTG) of the BL21 strain containing the Lcl overexpression plasmid, the recombinant protein was purified on a Ni2+-NTA agarose column under denaturing conditions (8 M urea). Following sodium dodecyl sulfate

polyacrylamide gel electrophoresis (SDS-PAGE), the protein was electroeluted from the gel and with this purified protein antibodies (AB) were raised against L. pneumophila Lcl in pfd:Hollander rabbits. The specificity of the antibodies was tested using a total cell lysate of L. pneumophila. The antibodies were used to detect Lcl after SDS-PAGE using Western blot analysis with anti-rabbit antibodies as secondary antibodies and NBT/BCIP (Roche) for signal detection. The denatured proteins were refolded through dialysis Selleckchem Lapatinib and the concentration was determined

using a bovine serum albumin (BSA)-standard curve. The lpg 2644 gene, containing 19 repeat units of 45 nucleotides, was amplified from the L. pneumophila ATCC33152 genomic DNA with the primer pair 5′-TACATATGATACATCGAAATAAAGTCC-3′ and 5′-TAGAATTCTTAAAAGGCTCTTACAGC-3′. This fragment was cloned as an NdeI/EcoRI restriction fragment in the shuttle vector pMMBN and electroporated in L. pneumophila Philadelphia-1 [wild type (WT)/pMMBNlcl]. Expression of the lcl gene was induced by addition of 100 μM IPTG. Cloning procedures led to a spontaneous recombination of the VNTR region, resulting in an lcl gene containing 14 repeat units designated WT/pMMBNlcl(14). Fractionation of L. pneumophila Philadelphia-1 cultures was performed as described before (Vranckx et al., 2007). Briefly, the supernatant was concentrated by trichloroacetic acid

(TCA) precipitation (20% TCA final concentration) and the cells were lysed in a French pressure cell. To extract the inner membrane proteins from the membranes, the sediment was resuspended in 1.5 mL 10 mM Tris (pH 7.5) containing 1.5% sarkosyl and centrifuged. The outer membrane proteins were Galeterone resuspended in 500 μL 10 mM Tris, pH 7.5, and 10 mM EDTA, containing 1% Triton X-100. The quality of the cellular fractions was controlled by testing for the presence of DnaK, a cytoplasmic protein, LepB, an inner membrane protein, and Lpa, an outer membrane protein. WT bacteria grown to the stationary phase were added to a monolayer of A549, macrophage-like cells or A. castellanii (5 × 105 cells per well) at a multiplicity of infection (MOI) of 100. Bacteria overexpressing Lcl were added to a monolayer of A549 or macrophage-like cells also at an MOI of 100. For sampling, after 30 and 60 min, the supernatant was removed and the wells were washed three times with medium to remove the extracellular bacteria.

’ (pharmacist 12). ‘It depends on who gets paid.’ (pharmacist 18). GPs and pharmacists were asked about perceived barriers to collaboration.

Some GPs didn’t identify any barriers, others listed the expected issues; that is, time and poor communication. Several GPs and pharmacists mentioned payment as a potential issue. Pharmacists identified many more barriers which included time and poor communication but also lack of communication, GP attitudes, inaccessibility, lack of familiarity and motivation to interact. For example ‘doctors are a bit insular, they tend to socialise Cabozantinib molecular weight with each other and that actually carries over to the workplace, that kind of barrier, an invisible barrier . . .’ (pharmacist 1). ‘You can’t tell a doctor anything, he can’t learn from anybody he’s supposed to know it all . . .’ (pharmacist 7). ‘For some doctors, they look down on the pharmacist, they tell you what to do . . . they don’t treat you equally. . . .’ (pharmacist 13). Pharmacists also identified that GPs might feel threatened by pharmacist involvement or that there might be an element of territorialism involved. For example ‘I went on a conference. . . . It

got GPs and pharmacists together, you can see they are not very comfortable being together and in terms of providing health care for the patients, they think we are actually stealing their customers.’ (pharmacist 5). For example ‘. . . the GPs might feel that they’re Celecoxib a little bit under attack because they haven’t put their patients on asthma plans, stuff like that.’ (pharmacist 18). GPs

negated this, describing it as their role or responsibility PF-02341066 purchase in patient care. Pharmacists recognised this as well. For example ‘. . . the doctor should lead the team, that’s got nothing to do with territorialism, it’s . . .  accept[ing] responsibility . . .’ (GP 2). ‘. . . doctors still see themselves as the number one provider.’ (pharmacist 10). ‘For some doctors, they look down on the pharmacist, they tell you what to do . . . they don’t treat you equally.’ (pharmacist 13). Low morale of the GP was reported by some GPs and pharmacists and was clearly identified as a potential barrier to teamwork/improved relationships. Universally, the patient was also perceived to be a barrier to a team approach. For example ‘. . . some customers (patients), when you advise them something they never return to the GP or they go to the GP and they might have a different opinion . . . and that’s the problem. . . .’ (pharmacist 5), ‘The patient, if they think its too much trouble [to follow your advice] . . . if you talk to the patient they’ll say “I don’t have time to go see the doctor” that’s probably the main problem because they don’t see asthma as one of the biggest health problems, even though they’re using their puffer four or five times a day . . .’ (pharmacist 12).

Although the reverse PreGen4 primer had sequence mismatches with all the Bacteroides sequences, six sequences had 9–11 consecutive matching

sequences at the 3′ end (data not shown). Thus, the PreGen4 primers may potentially result in the nonspecific amplification of Bacteroides sequences described above. CH5424802 chemical structure Therefore, from the in silico analysis it was concluded that g-Prevo primers are more specific to ruminal Prevotella than PreGen4 primers. Based on their valid coverage and high specificity to ruminal Prevotella, the g-Prevo primers were selected to be used in this study. Real-time PCR quantification of Prevotella revealed that the relative abundance of this genus in the total rumen bacteria of sheep was as high as 19.7% (Table 3). On the other hand, the commonly cultivated ruminal Prevotella species, P. bryantii and P. ruminicola,

accounted for only 0.6% and 3.8%, respectively (Table 3). The relative abundance of Prevotella tended to increase when the animals were switched to a concentrate diet, although one animal showed no difference in the proportion of Prevotella in either diet (data not shown). In order to demonstrate the proportion of classical ruminal bacterial species, the relative abundance of individual species was aggregated (Table 3). The sum of the relative abundance this website of 12 representative rumen bacterial species in the two dietary conditions accounted for 2.4–4.9% of the total rumen bacteria. The relative abundance of the rumen fibrolytic species (F. succinogenes, R. albus and R. flavefaciens) tended to decrease in concentrate-fed sheep. In particular, the abundance of F. succinogenes decreased significantly (P<0.001)

when the sheep were fed a high-concentrate diet. The DGGE fingerprints of rumen Prevotella from the same diet showed a similar banding pattern and tended to cluster according to the diet, although a certain degree of animal-to-animal variation was observed (Fig. 1). The DGGE fingerprints revealed unique bands for either the hay or the concentrate diet, although there were common banding positions for the two dietary conditions. Comparative analysis of the ADP ribosylation factor DGGE profile across diet showed consistently more bands in samples from hay-fed animals (Fig. 1). A total of 139 16S rRNA gene sequences, 60 from sheep on a hay diet and 79 from sheep on a concentrate diet, were subjected to sequence analysis after discarding those suspected to be chimeras. Good’s coverages of the hay and concentrate libraries were 43.3% and 65.8%, respectively. Although the libraries were not comprehensive, we obtained diverse sequences of Prevotella, and diet specificity was supported by both DGGE and library analysis. Based on a 97% sequence similarity criterion (Stackebrandt & Goebel, 1994), only 17 clones (12.2%) from the two libraries were considered to represent the characterized rumen Prevotella species (P. ruminicola or P. bryantii) and the remaining 122 clones (87.

8). The infection was newly identified after the initiation of HAART (unmasking IRIS) in eight out of 18 cases

(44.4%). In the remaining 10 cases (55.6%), IRIS was diagnosed after worsening of a previously treated CNS infection (paradoxical IRIS). The median interval from HAART initiation to diagnosis of IRIS was 39 days (IQR 20–90 days). Table 3 shows demographic, clinical and immunological characteristics of patients who developed paradoxical and unmasking IRIS. In order to identify pretreatment variables associated with the risk of developing paradoxical IRIS, these patients were compared with those who did not experience a paradoxical reaction. We found, as the only difference between the two groups, that patients who did not develop IRIS were more likely to have had a previous AIDS-defining condition (51.1% vs. 0% for those developing paradoxical IRIS; P = 0.002). Patients developing IRIS RG7422 cell line had a more rapid immunological recovery than patients who did

not develop IRIS, as evidenced by a greater increase in CD4 count after find more 3 months of antiretroviral therapy (ART) (170 vs. 62 cells/μL, respectively; P < 0.025). At this time-point, the decrease in viral load was also greater among patients with paradoxical IRIS, but differences did not reach statistical significance (–2.6 vs. −1.8 log10 for those with paradoxical IRIS; P = 0.10). Patients who began HAART within ifenprodil 2 weeks after the diagnosis of a CNS infection were not at higher risk of developing paradoxical IRIS (50% vs. 65.8% for those who began HAART more than 2 weeks after diagnosis; P = 0.32). Figure 3 shows the cumulative probabilities of survival and the median survival time categorized by the development and type of IRIS. We did not find significant differences in survival between patients who developed paradoxical IRIS and those without IRIS. Eight (44.4%) of the 18 patients with IRIS received therapy

with steroids for a variable period depending on the response to therapy and other individual patient characteristics. None of the 10 patients who were not treated with steroids died, while three of the eight who received steroids died. In those three cases, mortality was directly attributed to IRIS. These three patients had PML. In our study, we observed a progressive decline in the incidence of CNS opportunistic infections during the first decade of the 21st Century. The overall rate of CNS infections decreased significantly from 8.3 cases per 1000 HIV-infected patients in the year 2000 to 1.4 in 2010. Since HAART became available, many studies have reported a decrease in the incidence of most opportunistic conditions related to HIV infection, including neurological infections [1-6, 20-22]. For example, a study performed in France by Abgrall et al. in 2001 showed a reduction of 34% in the risk of cerebral toxoplasmosis after the introduction of protease inhibitors [5].

cDNAs from total RNA were prepared with the ImProm-II™ Reverse Transcription System (Promega, Madison, WI) according to the manufacturer’s instructions. RT-PCR was performed using specific primers for the selected genes, and mRNA expression

was normalized to glyceraldehyde 3-phosphate dehydrogenase (GAPDH). PCR products were analyzed on 1% agarose gels visualized with ethidium bromide. All experiments were performed at least three times. The data shown are representative results of the mean ± SD of triplicate experiments. Differences were judged to be statistically significant when the P-value was < 0.05. We examined the hypothesis that Lactobacillus gDNA (p-gDNA) would inhibit TNF-α production based on our previous observation that Lactobacillus LTA reduces LPS-induced TNF-α production. THP-1 cells pretreated with 1 and 10 μg mL−1 of p-gDNA or S. aureus genomic DNA (a-gDNA) followed by re-stimulation with 0.5 μg mL−1 of LPS displayed significantly less check details LPS-induced TNF-α production (Fig. 1a). The inhibitory efficiency of gDNAs increased gradually with the gDNA pretreatment time (Fig. 1b). THP-1 cells treated with various concentrations of a-gDNA for 6 h showed a dose-dependent increase of TNF-α production, whereas

p-gDNA barely produced TNF-α compared to a-gDNA-treated cells (Fig. 2a). TNF-α production from THP-1 cells treated with 10 μg mL−1 of a-gDNA peaked at 6 h after stimulation and slowly decreased (Fig. 2b). As THP-1 cells are very sensitive to endotoxin, we tried to exclude GSK458 endotoxin contamination from prepared gDNA. All gDNA preparations were confirmed for the presence of endotoxin using a Limulus amebocyte lysate assay kit. Although endotoxin concentration remained below stimulatory levels (0.05 ng mL−1) throughout the study, we treated the prepared gDNA with polymyxin B before incubation with

THP-1 cells to test whether the experiments were affected by contamination. As shown in Fig. 2c, endotoxin-induced TNF-α decreased after pretreatment with 50 μg mL−1polymyxin B, but p-gDNA- or a-gDNA-mediated TNF-α production was not affected by polymyxin B, demonstrating that the media and gDNAs were not contaminated with endotoxin. To confirm whether gDNA can induce selleck inhibitor TNF-α production from THP-1 cells, prepared gDNA was treated with DNase. Control aDNA induced TNF-α but DNase-treated aDNA did not. p-gDNA modestly induced TNF-α production in both the DNase treated and untreated tests (Fig. 2d). In another experiment, DNase treatment of gDNA significantly inhibited DNA-mediated tolerance, further confirming that gDNA is responsible for the induction of TNF-α and the inhibition of LPS-induced TNF-α production (Fig. 2e). To identify which signaling pathway may be involved in gDNA-mediated TNF-α production, the signaling inhibitors were treated for 30 min before ligand stimulation. p-gDNA caused low basic TNF-α expression levels that were not affected by inhibitors.

“ODIN (once-daily darunavir in treatment-experienced patients) was a 48-week, phase III, randomized, Protein tyrosine phosphatase open-label trial comparing once-daily (qd) darunavir/ritonavir (DRV/r) 800/100 mg with twice-daily (bid) DRV/r 600/100 mg, both with an optimized background regimen [OBR; at least two nucleoside reverse transcriptase inhibitors (NRTIs)], in treatment-experienced, HIV-1-infected adults with no DRV resistance-associated mutations (RAMs) at screening. Week 48 analyses of virological response by subgroups are reported. A total of 590 patients were randomized to receive qd (n = 294) or bid (n = 296) DRV/r. Virological response (HIV-1 RNA < 50 copies/mL) was assessed according to: screening HIV-1 RNA (≥ or < 50 000 copies/mL), CD4 cell count, prior protease inhibitor (PI) use, number of active NRTIs in the OBR, presence of mutations (primary PI mutations, PI RAMs or M184V/I), gender, age, race, HIV-1 clade and adherence. Baseline characteristics were well balanced between arms and across subgroups.
