In the microheterogeneous ionic liquids that we used as examples, the polar subsets always form a single domain in all investigated liquids. Although the fluorous side chains are also more or less connected in one or, maximally, two domains, the alkyl phases are dispersed.Although approaches for performing genome-wide association studies (GWAS) are well developed, conventional GWAS requires high-density genotyping of large numbers of individuals from a diversity panel. Here we report a method for performing GWAS that does not require genotyping of large numbers of individuals. Instead XP-GWAS (extreme-phenotype GWAS) relies on genotyping pools of individuals from a diversity panel that have extreme phenotypes. This analysis measures allele frequencies in the extreme pools, enabling discovery of associations between genetic variants and traits of interest. This method was evaluated in maize (Zea mays) using the well-characterized kernel row number trait, which was selected to enable comparisons between the results of XP-GWAS and conventional GWAS. An exome-sequencing strategy was used to focus sequencing resources on genes and their flanking regions. A total of 0.94 million variants were identified and served as evaluation markers; comparisons among pools showed that 145 of these variants were statistically associated with the kernel row number phenotype. These trait-associated variants were significantly enriched in regions identified by conventional GWAS. XP-GWAS was able to resolve several linked QTL and detect trait-associated variants within a single gene under a QTL peak. XP-GWAS is expected to be particularly valuable for detecting genes or alleles responsible for quantitative variation in species for which extensive genotyping resources are not available, such as wild progenitors of crops, orphan crops, and other poorly characterized species such as those of ecological interest.
This study was conducted to determine whether low folate and vitamin B12 levels, as well as high homocysteine levels in pregnant women are associated with neural tube defects (NTDs) in Tunisia.

A total of 75 NTDs pregnancies and 75 matched controls were included in the study. Their vitamin B12, folate, and red blood cell folate concentrations were measured using a radio-immunoassay kit and total homocysteine concentrations were determined using a fluorescent polarization immunoassay.

Vitamin B12 and folate concentrations were lower in NTD-affected pregnant women than in controls (respectively, p = 0.009 and p < 0.001). Total homocysteine concentration was significantly higher in the NTDs group than in controls (p = 0.008). In the case group, the folate levels were positively related with vitamin B12 levels (r = 0.54; p < 0.001) and negatively correlated with total homocysteine levels (r = -0.19; p = 0.04). Besides, red blood cell folate levels were positively correlated with folate levels (r = 0.24; p = 0.02) and negatively correlated with total homocysteine levels (r = -0.37; p = 0.001).

Lower concentrations of folate and vitamin B12 are related to the increased risk of NTDs. Both folate and vitamin B12 intake insufficiency could contribute to the increased risk of NTDs. A dietary supplement, combining folate and vitamin B12, might be an effective measure to decrease the NTDs incidence in Tunisia.

Percutaneous radiofrequency ablation (P-RFA) therapy is a widely applied treatment for small hepatocellular carcinoma (HCC); however, local recurrence is a major issue of HCC located at the surface of the liver (surface HCC). The aim of this study was to compare the outcome of laparoscopic hepatic resection (LH) and P-RFA for surface HCC in case-control patient groups using the propensity score.

Between 2011 and 2013, 40 and 52 patients underwent LH and P-RFA for surface HCC (≤3cm, 1-3 nodules). To correct the difference in clinicopathological factors between the two groups, propensity score matching was used at a 11 ratio, which resulted in a comparison of 27 patients/group. We compared outcomes between the two groups, with special reference to local recurrence.

Clinicopathological variables were well balanced between the two groups. One patient in the LH group was converted to open surgery due to adhesion. The incidence of complications was 0% in the P-RFA group and 15% (four patients) in the LH group (P = 0.11); however, none of these four patients in the LH group sustained severe complications. The duration of hospitalization following treatment was longer in the LH group than in the P-RFA group (12.6 vs 7.6days, P <0.01). The incidence of local recurrence was lower in the LH group (0%) than in the P-RFA group (eight patients [30%], P = 0.004).

LH is an effective treatment for surface HCC with regard to control of local recurrence.

Mutations in known JBTS genes account for approximately half of the cases. By homozygosity mapping and whole-exome sequencing, we identified a novel locus, JBTS23, with a homozygous splice site mutation in KIAA0586 (alias TALPID3), a known lethal ciliopathy locus in model organisms. Truncating KIAA0586 mutations were identified in two additional patients with JBTS. EPZ020411 mw One mutation, c.428delG (p.Arg143Lysfs*4), is unexpectedly common in the general population and may be a major contributor to JBTS. We demonstrate KIAA0586 protein localization at the basal body in human and mouse photoreceptors, as is common for JBTS proteins, and also in pericentriolar locations. We show that loss of TALPID3 (KIAA0586) function in animal models causes abnormal tissue polarity, centrosome length and orientation, and centriolar satellites. We propose that JBTS and other ciliopathies may in part result from cell polarity defects.We report the prenatal detection of a de novo unbalanced complex chromosomal rearrangement (CCR), in a fetus with growth delay and bilateral cataracts. Standard karyotype and FISH analyses on amniotic fluid revealed a complex de novo translocation, resulting in a 46,XY,t(1;12;14)(q42;q14;q32) karyotype. CGH-array showed a significant deletion of 387 kb at 12q14.3, at a distance of only 200-700 kb from the breakpoint at 12q14, which encompassed the HMGA2 gene and occurred de novo. Although 12q14 microdeletions are associated with growth delay in several reports in the literature, we present here the smallest deletion prenatally detected, and we detail the clinical description of the fetus. The correlation between cataracts and this complex genotype is puzzling. Among the genes disrupted by the breakpoint in 12q14, GRIP1 has been associated with abnormal eye development in mice, including lens degeneration. Interestingly, HMGA2 is expressed in the mouse's developing lens, and its expression is decreased in lens of elderly humans, correlated with the severity of lens opacity. In this report, we refine the link between HMGA2 loss of function and growth delay during prenatal development. We also discuss the correlation between cataracts and genotype in this unbalanced CCR case of unexpected complexity.Cornelia de Lange syndrome (CdLS) is a rare dominantly inherited genetic multisystem developmental condition with considerable phenotypic and allelic heterogeneity. Missense and in-frame deletions within the SMC1A gene can be associated with epilepsy and milder craniofacial features. We report two females who presented with developmental delay and developed isolated medically refractory seizures with unrevealing initial laboratory, imaging and genetic evaluations. Whole exome sequencing (WES) analyses were performed and were instrumental in uncovering the genetic etiology for their conditions. WES identified two novel de novo heterozygous frameshift mutations in the SMC1A gene [c.2853_2856delTCAG (p.Ser951Argfs*12) and c.3549_3552dupGGCC (p.Ile1185Glyfs*23)]. We also observed marked skewing of X-inactivation in one patient. The individual with the p.Ser951Argfs*12 mutation represents an extreme on the CdLS phenotypic spectrum, with prominent neurological involvement of severe developmental delay and refractory epilepsy, with mild craniofacial features. Both individuals eventually had incomplete clinical responses to therapy with valproic acid. We review previous reports of SMC1A mutations with epilepsy. SMC1A should be included in clinical gene panels for early infantile and early childhood epileptic encephalopathy.Three-dimensional cell spheroids prepared without using any artificial scaffold materials are desirable for cell-based transplants. However, conventional cell culture systems are inefficient for rapid, large-scale and non-cytotoxic generation of size-controlled spheroids (>1 mm diameter) that are required for tissue regenerative therapy application. In this study, we prepared millimeter-order spheroids of adipose-derived mesenchymal stem cells (ADSCs) by controlling the spheroid size (diameter range 0.4-2.5 mm). Notably, spheroid generation required only one day of culture on charged culture dishes. Almost all spheroid-derived ADSCs were viable and produced adhesion molecules and growth factors, which play an important role in tissue regeneration. Moreover, spheroid-derived ADSCs could infiltrate and recellularize collagenous tissue membranes in vitro. The ADSC spheroids developed in this study could be directly (without additional processing) used for cell-based tissue regeneration therapy. Furthermore, the rapid scale-up process and noncytotoxic generation of spheroids would also enable other applications such as use as screening models for drug discovery.
To describe the associations between body composition and hormonal and inflammatory factors measured 5 years prior and tibial cartilage volume in young adults, and to explore if these factors contribute to the sex difference in tibial cartilage volume.

Subjects broadly representative of the young adult Australian population (n = 328, ages 31-41 years, 47.3% women) were selected. They underwent T1-weighted fat-suppressed magnetic resonance imaging (MRI) of their knees. Tibial cartilage volume was measured from MRI. Sex hormone binding globulin (SHBG) and testosterone in a subset of women and C-reactive protein (CRP) level and fibrinogen in both sexes were measured 5 years prior. Body mass index (BMI), fat mass, and lean mass were calculated from height, weight, and skinfolds.

In multivariable analyses, correlates of tibial cartilage volume included lean body mass (β = 26.4 mm(3) ; 95% confidence interval [95% CI] 13.6, 39.1), fat mass (β = -11.8 mm(3) ; 95% CI -22.2, -1.4), and fibrinogen (β = -146.4 mm(3) ; 95% CI -276.4, -16.4), but not BMI, testosterone, or CRP level. In women, SHBG was positively associated with tibial cartilage volume (β = 0.67 mm(3) ; 95% CI 0.14, 1.20) and Free Androgen Index was negatively associated with lateral tibial cartilage volume (β = -0.04 mm(3) ; 95% CI -0.07, 0.00). Men had 13% more tibial cartilage volume (500 mm(3) ) than women. The magnitude of this association decreased by 38%, 20%, and 37% after adjustment for lean body mass, fat mass, and fibrinogen, respectively.

Body composition, sex hormones, and fibrinogen correlate with knee cartilage volume in young adult life. Sex difference in knee cartilage volume is contributed largely by variations in body composition and/or fibrinogen.
