Starch binding domains of starch synthase III from Arabidopsis thaliana (SBD123) binds preferentially to cell wall polysaccharides rather than to starch in vitro. Transgenic plants overexpressing SBD123 in the cell wall are larger than wild type. Cell wall components are altered in transgenic plants. Transgenic plants are more susceptible to digestion than wild type and present higher released glucose content. Our results suggest that the transgenic plants have an advantage for the production of bioethanol in terms of saccharification of essential substrates...

INTRODUCTION: This study explored schizotypy as a familial liability marker for schizophrenia-spectrum disorders (SSD) by examining: 1) the aggregation of schizotypy in families with a SSD patient, 2) whether familial resemblance of schizotypy is associated with ridge dissociations (RD), another SSD liability marker, 3) whether schizotypy aggregation patterns influence patients' psychopathology. METHODS: The sample comprised 30 SSD patients and 82 healthy first-degree relatives...

Microalgae biomass has been recognised as a sustainable bio-product to replace terrestrial biomass in biofuel production. The microalgae industry has high operating costs, specifically on harvesting and biomass recovery. Therefore, the development of an efficient harvesting method is crucial to the minimisation of production cost. A statistical analysis via response surface methodology was used to investigate the optimisation of harvesting efficiency using alum and chitosan as a coagulant. Growth rate and biomass productivity were also determined...

BACKGROUND: Ovarian tissue cryopreservation (OTC) is the only option available to preserve fertility in prepubertal females with neuroblastoma (NB), a childhood solid tumor that can spread to the ovaries, with a risk of reintroducing malignant cells after an ovarian graft. PROCEDURE: We set out to determine whether the analysis of TH (tyrosine hydroxylase), PHOX2B (paired-like homeobox 2b), and DCX (doublecortin) transcripts using quantitative reverse transcriptase polymerase chain reaction (RT-qPCR) could be used to detect NB contamination in ovarian tissue...

Psychopathological symptoms and cognitive impairment are related to psychosocial functioning. However, the nature of the association of cognitive impairment with psychosocial functioning still remains under scrutiny. We aimed to examine the relationships of premorbid adjustment, lifetime psychopathological dimensions, and cognitive performance with the typical level of psychosocial functioning during the previous year. We assessed ninety patients with schizophrenia spectrum disorders and affective disorders with psychotic symptoms to collect data on premorbid adjustment, lifetime psychopathological dimensions, cognitive performance and psychosocial functioning...

Treacher Collins Syndrome (TCS) is a rare congenital disease (1:50 000 live births) characterized by craniofacial defects, including hypoplasia of facial bones, cleft palate and palpebral fissures. Over 90% of the cases are due to mutations in the TCOF1 gene, which codifies the nucleolar protein Treacle. Here we report a novel TCS-like zebrafish model displaying features that fully recapitulate the spectrum of craniofacial abnormalities observed in patients. As it was reported for a Tcof1(+/-) mouse model, Treacle depletion in zebrafish caused reduced rRNA transcription, stabilization of Tp53 and increased cell death in the cephalic region...

OBJECTIVE: To identify the presence of environmental factors linked to the onset of allergies and asthma in the homes of children participating in an early detection program that were identified with sensitivity to common allergens in the region of Sonora, Mexico. METHODS: A walkthrough assessment was carried out in the homes of sensitized children; the research tools were the questionnaire and environmental checklist proposed by the Lowell Healthy Homes Program of the University of Massachusetts-Lowell...

We know from the violence literature that a distinct sex disparity exists in the perpetration of other-directed violence (ODV). Some scholars suggest that this disparity is explained in part by gendered reactions to stress, strain, or violence victimization, in which males and females engage in different coping mechanisms, with males more likely to engage in ODV than females. Using a college sample, we investigate the behavioral responses of male and female victims of psychological intimate partner abuse. We find that although there is a sex disparity in the use of ODV as a coping mechanism, there is also a distinct gender orientation disparity...

AIM: Very few studies have compared epidemiological characteristics of patients with Familial Colorectal Cancer Type X (FCCTX) with sporadic colorectal cancer (S-CRC). The aim of the study was to compare clinicopathological characteristics and survival in FCCTX and S-CRC patients from a historically isolated geographic region. METHOD: A retrospective study was carried out of patients with S-CRC and FCCTX treated in the Canary Islands. Family and personal history of colorectal cancer (CRC), genetic (microsatellite instability), immunohistochemical and clinical variables were recorded...

Little is known about the interaction of nanoparticles (NPs) with soil constituents and their effects in plants. Boron (B), an essential micronutrient that reduces crop production at both deficiency and excess, has not been investigated with respect to its interaction with cerium oxide NPs (nano-CeO2). Considering conflicting results on the nano-CeO2 toxicity and protective role as antioxidant, their possible modulation on B toxicity in sunflower (Helianthus annuus L.) was investigated. Sunflower was cultivated for 30 days in garden pots containing original or B-spiked soil amended with nano-CeO2 at 0-800 mg kg(-1)...

A series of penta- and heteropentadienyl [CH2CHCHCHXBe](+), (X = CH2, O, NH, S) complexes has been theoretically studied. All calculated complexes show beryllium atoms with two, three, and five coordination numbers. The density functional theory (DFT) was used to determine the electron and structural behavior of those beryllium complexes. The nature of the ligands plays an important role in the form of binding to the beryllium atom. Beryllium structures 1-4 are able to coordinate only one hydrogen molecule...

We explore the convergence of the dual-space microscopy (DSM) phase-recovery algorithm. DSM is an optical microscopy technique based on simultaneous observation of an object in the position and momentum spaces. We present one-dimensional (1D) simulations of this technique, demonstrating that the DSM technique is capable to resolve periodic and nonperiodic structures with a resolution well below the Rayleigh resolution limit. Using a simple and faster 1D version of the full 2D DSM algorithm, we simulated the DSM technique for thousands of different samples...

African ancestry alleles may contribute to CKD among Hispanics/Latinos, but whether associations differ by Hispanic/Latino background remains unknown. We examined the association of CKD measures with African ancestry-specific APOL1 alleles that were directly genotyped and sickle cell trait (hemoglobin subunit β gene [HBB] variant) on the basis of imputation in 12,226 adult Hispanics/Latinos grouped according to Caribbean or Mainland background. We also performed an unbiased genome-wide association scan of urine albumin-to-creatinine ratios...

Several studies report that (+)-usnic acid, a lichen secondary metabolite, inhibits growth of different bacteria and fungi; however, the mechanism of its antimicrobial activity remains unknown. In this study, we explored the ability of usnic acid, obtained from Usnea amblyoclada, as an antibiofilm agent against azole-resistant and azole-sensitive Candida albicans strains by studying the cellular stress and antioxidant response in biofilms. The biofilm inhibitory concentration of usnic acid (4 µg/mL) exhibited a significant biofilm inhibition, 71...
