C-EnterNet used the laboratory-based surveillance system for reportable illnesses in place in Ontario in which it is mandatory for clinical laboratories to Sirolimus mw report each case of reportable disease to the local public health authority. C-EnterNet enhanced this system in ROW public health by implementing a systematic

follow-up of each reported case by a public health inspector using a standardized questionnaire (available at http://www.phac-aspc.gc.ca/c-enternet/pdf/campylobacter-w_e.pdf). Detailed information on demographics and disease symptoms, as well as exposure to 14 potential risk factors (including travel) which may have occurred during a given number of days prior to the disease onset (ie, the number of days is disease specific and accounts for varying length of incubation) was collected.

In addition, the enteropathogen isolates were forwarded to the Ontario Agency for Health Protection and Promotion’s Toronto Public Health Laboratory in Etobicoke, Ontario for further characterization depending on the pathogen genus. These laboratory results were then sent to the ROW public health authorities, who ultimately provided the depersonalized epidemiological and microbiologic data to C-EnterNet, Public Health Agency of Canada. Potential AG-014699 price duplicates were systematically checked and removed by ROW public health personnel through their routine work prior to providing the dataset to C-EnterNet. Ethics approval was provided through the ROW public health ethics review. Reported cases that could not

be reached for the follow-up interview were considered as lost to follow up and removed from the dataset (n = 145). Outbreak-related cases, as defined by ROW public health authority on the basis of epidemiological or laboratory evidence, were removed as well. The remaining cases were classified as either TRC or DC as follows. TRC were defined as cases for which travel outside Canada prior to the disease onset were recorded and the expected incubation period overlapped the travel time. More specifically, the delay between departure and onset dates had to be greater or equal to the minimum incubation period and the delay between return and onset dates less than the Sulfite dehydrogenase maximum incubation period. The minimum and maximum incubation periods were from Heyman:22 14 to 28 days for amebiasis, 1 to 10 days for campylobacteriosis, 1 to 12 days for cryptosporidiosis, 1 to 14 days for cyclosporiasis, 3 to 25 days for giardiasis, 15 to 50 days for hepatitis A, 0 to 3 days for non-typhoidal salmonellosis, 0 to 4 days for shigellosis, 7 to 21 days for typhoid and paratyphoid fever, 2 to 10 days for VTEC infection, and 3 to 7 days for yersiniosis. Cases not classified as TRC were considered as DC cases. In each record, a free text field allowed the public health inspector, responsible for case follow-up, to indicate his/her opinion on the probable source.

Student’s t-test was used to compare the mean AIs of various clinical isolates with MG 1655 (nonaggregating) and UPEC 536 (aggregating) cultures.

Light and phase-contrast microscopy (Nikon Eclipse E600) was used to verify Z-VAD-FMK mw the absence of aggregates in nonaggregating cultures. AIs were not determined for these cultures. Calcofluor White stain (Sigma) was used to assess the presence of cellulose in aggregates by epifluorescence microscopy (Nikon Eclipse E600) according to the manufacturer’s instructions. Field emission cryoscanning electron microscopy (cSEM) was performed on a Philips XL30 S-FEG with an EDAX Phoenix EDS detector and a Gatan Alto cryo-trans system at the Research Centre for Surface and Materials Science, University 5-Fluoracil of Auckland. UPEC 536 cultured overnight in R with shaking forms large aggregates. The aggregates are not present in the overnight culture if the media are supplemented with 10 μM FeCl3 (RF). To investigate further,

the overnight RF culture was used to inoculate fresh R and RF cultures at a dilution of 1 in 100 and we observed that while initially (2–4 h) aggregates formed in both cultures, they did not persist in the RF culture. We sought to quantify the aggregation using the AI. Determination of the AI is a destructive test and so measurements are made from 10-mL cultures at timed intervals. The methodology provides consistently reproducible data and shows that aggregates form in both R and RF, but only persist in R (Fig. 1a). We did not observe aggregation with a laboratory strain of E. coli K12, MG 1655. We did observe aggregation with seven O-methylated flavonoid of 12 UPEC strains isolated from UTI patients at Auckland Hospital (Table 1). We hypothesized that the presence of iron might stimulate dispersion from aggregates, and so investigated whether aggregate dispersal would be seen upon the provision of iron. We grew UPEC 536 aggregates in R to maximal aggregation (about 4 h after 1 : 100 inoculation from an overnight RF culture), FeCl3 was added to 10 μM, and AIs were measured

at timed intervals. The provision of iron clearly dispersed the aggregates in a quantifiable manner (Fig. 1a, Table 1). UPEC can acquire iron from numerous iron sources in vivo, including ferritin, transferrin, and lactoferrin via siderophores and haem and haemoglobin via direct binding to receptors (Torres et al., 2001; Hagan & Mobley, 2009; Henderson et al., 2009). Iron from these sources induces dispersal (Table 2). We conclude that the provision of usable iron, or the acquisition of iron, is a signal for aggregated, iron-starved cells to disperse. Iron is not the only metal ion to play an important role in bacterial function (Hantke, 2005; Papp-Wallace & Maguire, 2006; Rink & Hasse, 2007; Sabri et al., 2009).

, 2007; van Es et al., 2007, 2008, 2009; Schymick et al., 2007b; Cronin et al., 2008; Chio et al., 2009c; Landers et al., 2009; Simpson et al., 2009). Interestingly, three of them have identified

factors related to the axonal compartment or vesicle release. One study on 1821 sporadic ALS patients and 2258 controls from the US and Europe found no association I-BET-762 price in itself, but identified an SNP in the gene encoding the kinesin-associated protein 3 (KIFAP3) to be associated with disease duration (Landers et al., 2009). The variant associated with increased survival was associated with decreased KIFAP3 expression. In another study involving 781 patients and 702 controls, a polymorphic marker in the elongation protein 3 homolog (ELP3) gene was found to protect against the occurrence of ALS (Simpson et al., 2009). This finding were shown to have biological

relevance as, within the same study, an independent genetic screen in Drosophila identified two different loss-of-function mutations in the fly homologue of Elp3 that induced aberrant axonal outgrowth and synaptic defects. Furthermore, the knockdown of Elp3 in the zebrafish induced selleck chemical motor axonal abnormalities, and lower expression levels of Elp3 were found in the brains of individuals with the ALS at-risk genotype. Taken together, these results suggest that low Elp3 expression renders the motor neuron vulnerable to neurodegeneration (Simpson et al., 2009). Interestingly, Elp3 is mainly localized in the cytosol in neuronal cells (Pokholok et al., 2002; Simpson et al., 2009),

suggesting the existence of additional cytosolic targets for acetylation in these cells. Given the fact that α-tubulin acetylation is a key regulator of axonal transport (Westermann & Weber, 2003; Hammond et al., 2008) and that impairment of this process leads to neurodegeneration in general and to motor neuron degeneration in particular (De Vos et al., 2008), α-tubulin emerged as an obvious candidate for acetylation (Gardiner et al., 2007). In fact, an elegant study by Creppe et al. (2009) demonstrated that Elp3 acetylates α-tubulin and regulates migration and differentiation of cortical neurons. Furthermore, the role SPTLC1 of Elongator on α-tubulin acetylation was recently corroborated in C. elegans, in which Elongator mutants also exhibited decreased neurotransmitter levels (Solinger et al., 2010), perhaps due to defects in vesicle transport and release. Of interest, mutations in Elp1, the scaffolding subunit for the enzymatically active Elp3, cause familial dysautonomia, a recessive degenerative disease of the autonomic nervous system (Anderson et al., 2001; Slaugenhaupt et al., 2001). Recently, another genome-wide association study of 2323 individuals with sporadic ALS and 9013 control subjects identified unc-13 homolog A (UNC13A) as susceptibility gene for sporadic ALS (van Es et al., 2009).

The exact cause of microstomia of generalized RDEB is not known, although it seems likely that it reflects the scarring of the buccal and labial mucosa and commissures1,5,9,28. The microstomia of generalized RDEB gives rise to a wide variety of functional problems that include difficulties in eating, speech, and oral hygiene maintenance. Additionally, dental treatment and general anaesthesia can BIBW2992 concentration be complicated and the aesthetics of the lower face compromised19,22,25,36,79. Cancer risk.  Squamous cell

carcinoma (SCC) has been described as the leading cause of death in patients with EB80. Few cases affecting the oral cavity have been reported. The tongue is the most commonly affected site, although tumours on the lip and the hard palate have also been learn more reported. The age of diagnosis has ranged from 25 to 54 years of age. At least three cases have been lethal5,28,77,81. Periodontal disease.  Extensive plaque deposits

have been reported on most patients4,11,16,27,41,45. Mean plaque score measured using a modification of the index of O’Leary revealed higher values for patients with DEB (n = 23; 18 RDEB, five DDBE) in the primary (33.7 ± 31.3) and secondary dentitions (28.6 ± 31.6) when compared to a control group (1.8 ± 3.3/4.6 ± 5.6, respectively)20. Mean gingivitis scores (using the simplified gingival index) have been found to be significantly greater in patients with DEB (n = 23; 18 RDEB, five DDEB) in both primary (21.5 ± 29) and permanent dentitions (27.5 ± 34.9) when compared to a control group (0.00/2 ± 4.6, respectively)20. There does not appear to be an increased risk of periodontal membrane and bone involvement in MG-132 in vivo RDEB27,36. Caries.  Patients with RDEB have significantly

higher caries scores (DMFT, DMFS, combined DMFS with dmfs and combined DMFT with dmft) than control patients (Images 28 and 29)5,12,19,20. Only few patients have been reported to have cellulitis secondary to periapical infection.30 Occlusal abnormalities.  A variety of occlusal anomalies have been described in RDEB including increased overjet and overbite22, severe crowding12,22,49, cross-bite molar relationship12, and class II skeletal malocclusion22,48. Some of the anomalies may be due to reduced alveolar arches (secondary to growth retardation) and collapse of the dental arches (secondary to soft tissue retardation)8. A cephalometric study of 42 patients with RDEB found significantly smaller jaws in these patients50, thus adding weight to the suggestion that significant dento-alveolar disproportion and dental crowding are features of RDEB. Dental maturity.  Two studies have been published on dental maturity and dental development in patients with RDEB finding no significant delay82,83. Facial Growth.

[14] Mammalian TLR comprise a large family consisting of at least 11 members. TLR1–9 were found to be conserved between humans and mice. TLR10 is presumably functional in humans but non-functional in mice. Similarly, mouse TLR11 is functional, but there is a stop codon in the human TLR11 gene, which results in a lack of production of human TLR11.[15] The cytoplasmic OSI 744 portion of TLR shows high similarity to that of the

interleukin (IL)-1 receptor family, and is termed a Toll/IL-1 receptor (TIR) domain. Despite this similarity, the extracellular portions of both types of receptors are structurally unrelated. The IL-1 receptors possess an immunoglobulin-like domain, whereas TLR bear leucine-rich repeats in the extracellular domain. Functionally, a critical role of TLR4 in the

recognition of the microbial component was initially characterized.[16] Subsequently, it has been established that individual TLR play important roles in recognizing specific microbial components derived from pathogens including bacteria, fungi, protozoa and viruses. Toll-like receptor 2 is essential Selleck Ixazomib in the recognition of microbial lipopeptides and peptidoglycan derived from Gram-positive bacteria. TLR1 and TLR6 cooperate with TLR2 to discriminate subtle differences between triacyl and diacyl lipopeptides, respectively. TLR2 forms heterophilic dimers with TLR1 and TLR6, both of which are structurally related to TLR2.[17] TLR4 is the receptor for LPS derived from the outer membrane of Gram-negative bacteria. TLR5 recognizes flagellin. TLR3 is implicated in the recognition of viral dsRNA associated with viral replication, whereas TLR7 and TLR8 are implicated in viral-derived ssRNA recognition. Thus, polyinosinic–polycytidylic acid (polyI:C), which is a synthetic mimetic for dsRNA, can induce TLR3 signaling.[18] TLR9 is essential in unmethylated

(CpG) DNA recognition.[4] There are two types of ligands, exogenous and endogenous, for TLR4.[19] As described above, TLR4 is an essential receptor for bacterial endotoxin or LPS recognition. In addition however to LPS, other exogenous ligands are F protein from respiratory syncytial virus, chlamydial heat shock protein (Hsp)60 and taxol, a plant-derived anticancer reagent that mimics the action of LPS in mice but not in humans.[19] Endogenous ligands of TLR4 comprise fibrinogen, fibronectin, heparan sulfate, hyaluronic acid, and Hsp60 and Hsp70. However, all of these endogenous ligands require very high concentration to activate TLR4. It has been shown that contamination of LPS in Hsp70 preparation confers ability to activate TLR4. LPS is a very potent immuno-activator and accordingly, TLR4 can be activated by a very small amount of LPS, contaminating these endogenous ligand preparations.[4, 19-22] Therefore, we need careful attention in biological research using these endogenous ligands. The different TLR and their corresponding ligands are described in Table 1.

Therefore, a study with a larger sample size is needed to clarify the relationship between anti-TNF therapy and endothelial function in patients with RA. In addition, we only performed FMD examination, and did not examine microvascular endothelial function or induced macrovascular dilation using glyceryl trinitrate, which are well-known global measures of endothelial function. Furthermore, the links between systemic inflammation, and vascular function and morphology in patients with RA are not completely supported, as noted in a recent systematic review.[44] Further studies, involving evaluation of both microvascular and macrovascular endothelial function, with much larger numbers of subjects and longer

follow-up periods are warranted to validate the present findings. In conclusion, the present results demonstrate significant associations between the FMD measurements, disease activity and anti-TNF therapy among randomly selected patients with RA. see more Anti-TNF therapy may influence endothelial function more than conventional DMARD therapy.

“To validate the Thai version of the Health Assessment Questionnaire (HAQ) for patients with psoriatic arthritis (PsA). The Thai version of the HAQ was administered to 47 patients with PsA attending our rheumatology clinic. Clinical assessments included the measures of disease activity, disease severity and functional status. The correlation of the single items and total score of the Thai HAQ with the measures of disease activity, disease severity and functional status was assessed using Pearson’s correlation or Spearman rank correlation, as appropriate. Of 47 patients who fulfilled the Classification Criteria for Psoriatic Arthritis (CASPAR), 21 were male. Their mean age ± standard deviation (SD) and Interleukin-3 receptor mean disease duration ± SD were 49 ± 10 years and 6.97 ± 6.17 years, respectively. Spondylitis was the most common manifestation (38%). The mean Thai HAQ score was 0.47. The single items and total score of the Thai HAQ were moderately to highly correlated with several measures of disease activity (r = 0.32–0.81, P < 0.01), except for swollen joint count (r = 0.16). For functional status and disease severity, the Thai HAQ was moderately correlated with grip strength (r = −0.39, P < 0.01), but poorly correlated with the range of spinal movement and the number of damaged joints. (r = −0.01 to 0.17).

succinogenes S85. In fact, intracellular xylanase activity of strain R-25 was induced by the supernatant of F. succinogenes S85 culture and xylooligosaccharides medium. Induction of xylanolytic enzyme by xylooligosaccharides was reported on known rumen bacterium S. ruminantium and Prevotella bryantii (Cotta & Whitehead, 1998; Miyazaki et al., 2005). Fibrobacter succinogenes S85 can degrade the xylan chain of hemicellulose by its own xylanolytic enzymes (Matte & Forsberg, 1992; Matte et al., 1992). isocitrate dehydrogenase inhibitor However, recent

genomic study indicates that F. succinogenes S85 lacks many of the genes necessary to transport and metabolize the hydrolytic products of noncellulose polysaccharides such as xylan (Suen et al., 2011). Therefore, strain R-25 might be able to utilize xylooligosaccharides produced by F. succinogenes S85 in the coculture without competition. Although the DM digestion was improved in coculture of strains R-25 and F. succinogenes S85, the fermentation products of these two strains accumulated. As d-lactate and succinate are rarely accumulated in the rumen, these organic acids should be removed to maintain the function of F. succinogenes S85 and Dabrafenib datasheet strain R-25. Selenomonas ruminantium is known as a succinate-utilizing and propionate-producing bacterium in the rumen (Strobel & Russell, 1991) and is classified into two subspecies, lactate nonutilizing subsp. ruminantium and lactate utilizing subsp. lactilytica (Flint & Bisset, 1990).

Our previous studies showed that S. ruminantium S137, which was a lactate–succinate-utilizing strain, enhanced fibrolytic activity of F. succinogenes (Sawanon et al., 2011) and Ruminococcus flavefaciens Carnitine palmitoyltransferase II (Sawanon

& Kobayashi, 2006). Therefore, S. ruminantium S137 was used in this study as a lactate–succinate-utilizing bacterium to determine whether this strain is helpful for metabolizing organic acids that accumulate in coculture of strains R-25 and F. succinogenes S85. Rice straw digestion and bacterial population were highest in triculture. As predicted, lactate/succinate consumption and propionate production was observed when S. ruminantium S137 was included to form a triculture. These observations strongly suggest that the consumption of d-lactate and succinate by S. ruminantium S137 could improve the growth of strains R-25 and F. succinogenes S85, resulting in increased digestion in the triculture. Other than S. ruminantium, there are many kinds of rumen bacteria that can metabolize lactate and/or succinate, such as Megasphaera elsdenii, Schwartzia succinivorans, Succiniclasticum ruminis, and Veillonella parvula. These metabolite utilizers may play a similar role to S. ruminantium S137 in ruminal fiber digestion. Although rice straw digestion was not observed in mono- and coculture of strain R-25 and S. ruminantium S137, metabolites were detected in these cultures. Probably, these strains utilized soluble sugars derived from rice straw for their growth in the culture without F. succinogenes S85.

05). None of the LAB strains stimulated AFB1 accumulation in any of the fungal strains assayed. On the contrary, toxin production of A. flavus RC2053 and A. flavus RC2055 was totally inhibited by L. fermentum L23. It is likely that the low concentration of AFB1 in the presence of Lactobacillus strains could

be due to low mycelial biomass formation. Growth inhibition could directly affect AFB1 production as a result of low synthesis of the enzymes involved. Furthermore, AFB1 is a secondary metabolite that does not occur during primary growth of fungus, so that growth inhibition may reduce its production. In this study we have showed that there could exist a relationship between fungal growth and AFB1 production. In fact, these results showed that minimal yields of toxin coincided with see more minimal mycelial growth. Tukey’s test of the data revealed the influence of L. fermentum L23 and L. rhamnosus L60 on growth parameters (lag phase and growth rate) and AFB1 production. Our results agree with Zinedine Ceritinib et al. (2005), who demonstrated the ability of some strains of LAB to reduce the initial concentration of AFB1 in MRS broth.

Similar observations were made by Aryantha & Lunggani (2007), who observed that L. plantarum, L. fermentum and Lactobacillus delbrueckii significantly inhibited fungal growth of A. flavus and AFB1 production. Dalié et al. (2010) established that the main LAB recognized

for their ability to limit mycotoxinogenic mould growth belong to the genera Lactococcus and Lactobacillus, including L. rhamnosus, in agreement with our results. These results reflect a strong ability to inhibit growth rate and AFB1 production by both Lactobacillus strains with a wide spectrum of antimicrobial activity and high probiotic potential. This suggest that the use of LAB with antifungal properties instead of chemical preservatives would enable the food and feed industry to produce organic food without chemical additives. In addition to the known excellent properties of Lactobacillus strains, they could enhance Liothyronine Sodium the nutritional value and prolong the conservation of food. These results are important given that these aflatoxicogenic fungi are natural contaminants of raw materials used for food and feed production, which could be effectively controlled by L. rhamnosus L60 and L. fermentum L23, both strains having probiotic properties. It is concluded that, under favourable conditions, the two lactobacilli strains not only inhibited aflatoxicogenic fungal growth, but also inhibited AFB1 biosynthesis. Future studies with L. rhamnosus L60 and L. fermentum L23 may test the application of these lactobacilli as biocontrollers of fungal contaminants and also to extend the self life of food and feed stuffs, approaching in situ their probiotic properties.

None of them had a history of psychiatric or neurological conditions, and all had normal http://www.selleckchem.com/products/ganetespib-sta-9090.html neurological and medical examinations, and Mini Mental State Examination scores in the normal range (27–30). Participants were not taking any medication known to affect motor cortical excitability at the time of the study and did not have any contraindications to TMS. All tolerated the TMS without any side effect or complication. All gave their

written informed consent to the study, which followed international guidelines and recommendations for the safe use of TMS (Rossi et al., 2009), had been approved by the local Institutional Review Board (Beth Israel Deaconess Medical Center, Boston, USA) and was conducted in adherence with the Declaration of Helsinki. We evaluated the effects of cTBS, a repetitive TMS intervention. Before and after cTBS, corticospinal excitability was assessed by recording MEPs in response to single-pulse TMS. EEG was recorded

concurrently, and TMS-induced electroencephalographic potentials and spectrum perturbation were evaluated. Finally, resting eyes-closed EEG was also evaluated. The stimulation set-up consisted of a Nexstim stimulator (Nexstim Ltd, Helsinki, Finland) for single-pulse TMS and a MagPro stimulator (MagVenture A/S, Farum, Denmark) for the cTBS intervention. We used figure-of-eight TMS coils delivering biphasic pulses (for Nexstim – mean diameter 50 mm and outer diameter 70 mm, each wing; for MagPro – inner diameter 35 mm and outer diameter AZD5363 manufacturer 75 mm, each wing). In all instances, the Nexstim neuronavigation system was used, ensuring reproducible and reliable coil placement within each experimental session. All participants underwent a brain magnetic resonance imaging (MRI) scan to rule out structural brain lesions and generate a high-resolution, anatomical

brain image to guide the TMS using the Nexstim neuronavigation system. A 3-Tesla scanner (GE) was used for MRI acquisition. For MEP measurement, surface electromyography (EMG) was recorded using pre-gelled, disposable Ag/AgCl electrodes with the active electrode over the first dorsal interosseus muscle (FDI), the reference electrode over the metacarpophalangeal joint and the ground electrode over the wrist. The EMG signal was acquired at 3 kHz, Amino acid filtered (10–500 Hz), amplified, displayed and stored for off-line analysis. Electroencephalography was recorded with a 60-channel TMS-compatible EEG system (eXimia EEG, Nexstim Ltd). This system is designed to avoid amplifier saturation after TMS pulses by using a sample-and-hold circuit that keeps the input of the amplifiers constant from 100 μs prestimulus to 2 ms poststimulus (Virtanen et al., 1999). The signals were sampled at 1450 Hz with 16-bit resolution and referenced to an electrode placed on the forehead. Impedance of each electrode was kept below 5 kΩ. Vertical electrooculogram (EOG) was recorded by two extra sensors.

This low use of lipid-lowering medication is in agreement with the findings of a cross-sectional study of 881 patients, of whom over 80% were on ART [7], and our own previous work evaluating a single site [8]. Although the role of

HAART-related hyperlipidaemia in HIV infection remains to be fully elucidated, the risk of cardiovascular disease is increased in those living with HIV and cholesterol abnormalities are a well-established risk factor [18,19]. Based on our results and other evidence, we Epacadostat manufacturer believe that viral hepatitis status should be included as a variable in studies evaluating cardiovascular disease in HIV infection. Several lines of evidence support the biological plausibility of our observations related to HCV. Hepatitis C virions associate with LDL, very low-density lipoprotein (VLDL) and HDL cholesterol in plasma [18–21]. Specifically, HCV envelope glycoprotein (E2) and HCV core protein interact with VLDL and LDL particles [22–25] and HCV core protein has been identified within cellular lipid storage droplets [26]. It is noteworthy that HCV viral load is diminished in HCV-infected patients following LDL plasmapheresis

[2]. HCV cell binding and entry is mediated, in part, by an LDL receptor-mediated process [26–29] and HDL may facilitate www.selleckchem.com/products/gsk-j4-hcl.html HCV entry through the class B type 1 scavenger receptor [28]. Recruitment of apolipoprotein E by nonstructural protein 5A (NS5A) is important for viral assembly and release of eltoprazine infectious HCV particles

[30,31]. The use of these receptors may not only explain how HCV gains intracellular entry and release but may also provide a mechanism by which HCV perturbs the lipid profile (i.e. by enhanced cellular lipid uptake). HCV proteins may also induce de novo triglyceride synthesis via activation of sterol regulatory element-binding protein 1c (SREBP1c) with concurrent diminished triglyceride secretion, leading to lower serum triglyceride levels and the well-recognized phenomenon of HCV-associated hepatic steatosis [32]. We have described an increase in lipid levels following clearance of chronic HCV infection with antiviral therapy in HIV/HCV coinfection that has been confirmed by others [8,15]. This further supports the validity of the results of the present study. There is little literature describing the influence of HBV on lipid levels. However, at least one group reported lower levels of triglycerides and HDL cholesterol in those chronically infected with HBV without HIV coinfection [33]. It is unclear if and how this observation is related to the observation that the HBV X protein induces lipid accumulation within hepatic cells [34]. Our analysis provides interesting preliminary information on the potential influence of HBV on lipid levels in HIV-infected patients on HAART. However, we acknowledge the limitations of this cohort analysis and the potential influence of confounders.
