Photographic protocol for image acquisition in craniofacial microsomia

Craniofacial microsomia (CFM) is a congenital condition associated with orbital, mandibular, ear, nerve, and soft tissue anomalies. We present a standardized, two-dimensional, digital photographic protocol designed to capture the common craniofacial features associated with CFM

Common Variants of the Liver Fatty Acid Binding Protein Gene Influence the Risk of Type 2 Diabetes and Insulin Resistance in Spanish Population

SummaryThe main objective was to evaluate the association between SNPs and haplotypes of the FABP1-4 genes and type 2 diabetes, as well as its interaction with fat intake, in one general Spanish population. The association was replicated in a second population in which HOMA index was also evaluated.Methods1217 unrelated individuals were selected from a population-based study [Hortega study: 605 women; mean age 54 y; 7.8% with type 2 diabetes]. The replication population included 805 subjects from Segovia, a neighboring region of Spain (446 females; mean age 52 y; 10.3% with type 2 diabetes). DM2 mellitus was defined in a similar way in both studies. Fifteen SNPs previously associated with metabolic traits or with potential influence in the gene expression within the FABP1-4 genes were genotyped with SNPlex and tested. Age, sex and BMI were used as covariates in the logistic regression model.ResultsOne polymorphism (rs2197076) and two haplotypes of the FABP-1 showed a strong association with the risk of DM2 in the original population. This association was further confirmed in the second population as well as in the pooled sample. None of the other analyzed variants in FABP2, FABP3 and FABP4 genes were associated. There was not a formal interaction between rs2197076 and fat intake. A significant association between the rs2197076 and the haplotypes of the FABP1 and HOMA-IR was also present in the replication population.ConclusionsThe study supports the role of common variants of the FABP-1 gene in the development of type 2 diabetes in Caucasians

Toxoplasma gondii infection and liver disease: a case-control study in a Northern Mexican population

<p>Abstract</p> <p>Background</p> <p>Infection with the protozoan parasite <it>Toxoplasma gondii </it>may cause liver disease. However, the impact of the infection in patients suffering from liver disease is unknown. Therefore, through a case-control study design, 75 adult liver disease patients attending a public hospital in Durango City, Mexico, and 150 controls from the general population of the same region matched by gender, age, and residence were examined with enzyme-linked immunoassays for the presence of anti-<it>Toxoplasma </it>IgG and anti-<it>Toxoplasma </it>IgM antibodies. Socio-demographic, clinical and behavioral characteristics from the study subjects were obtained.</p> <p>Results</p> <p>Seroprevalence of anti-<it>Toxoplasma </it>IgG antibodies and IgG titers did not differ significantly in patients (10/75; 13.3%) and controls (16/150; 10.7%). Two (2.7%) patients and 5 (3.3%) controls had anti-<it>Toxoplasma </it>IgM antibodies (<it>P </it>= 0.57). Seropositivity to <it>Toxoplasma </it>did not show any association with the diagnosis of liver disease. In contrast, seropositivity to <it>Toxoplasma </it>in patients was associated with consumption of venison and quail meat. <it>Toxoplasma </it>seropositivity was more frequent in patients with reflex impairment (27.8%) than in patients without this impairment (8.8%) (<it>P </it>= 0.05). Multivariate analysis showed that <it>Toxoplasma </it>seropositivity in patients was associated with consumption of sheep meat (OR = 8.69; 95% CI: 1.02-73.71; <it>P </it>= 0.04) and rabbit meat (OR = 4.61; 95% CI: 1.06-19.98; <it>P </it>= 0.04).</p> <p>Conclusions</p> <p>Seropositivity to <it>Toxoplasma </it>was comparable among liver disease patients and controls. Further studies with larger sample sizes are needed to elucidate the association of <it>Toxoplasma </it>with liver disease. Consumption of venison, and rabbit, sheep, and quail meats may warrant further investigation.</p

Bisbibenzyls, a New Type of Antifungal Agent, Inhibit Morphogenesis Switch and Biofilm Formation through Upregulation of DPP3 in Candida albicans

The yeast-to-hypha transition plays a crucial role in the pathogenesis of C. albicans. Farnesol, a quorum sensing molecule (QSM) secreted by the fungal itself, could prevent the formation of hyphae and subsequently lead to the defect of biofilm formation. The DPP3, encoding phosphatase, is a key gene in regulating farnesol synthesis. In this study, we screened 24 bisbibenzyls and 2 bibenzyls that were isolated from bryophytes or chemically synthesized by using CLSI method for antifungal effect. Seven bisbibenzyls were found to have antifungal effects with IC80 less than 32 µg/ml, and among them, plagiochin F, isoriccardin C and BS-34 were found to inhibit the hyphae and biofilm formation of C. albicans in a dose-dependent manner. To uncover the underlying relationship between morphogenesis switch and QSM formation, we measured the farnesol production by HPLC-MS and quantified Dpp3 expression by detecting the fluorescent intensity of green fluorescent protein tagged strain using Confocal Laser Scanning microscopy and Multifunction Microplate Reader. The DPP3 transcripts were determined by real-time PCR. The data indicated that the bisbibenzyls exerted antifungal effects through stimulating the synthesis of farnesol via upregulation of Dpp3, suggesting a potential antifungal application of bisbibenzyls. In addition, our assay provides a novel, visual and convenient method to measure active compounds against morphogenesis switch
