Prenatal stress was found to be a risk factor for infant temperamental unpredictability when combined with low social support perceived by the mother during pregnancy. Support of others, not previously examined in this context, can reduce the impact of prenatal stress.

The Ages & Stages Questionnaires Third Version (ASQ-3) identifies the risk of developmental delay in children aged 2 to 66months. The ASQ-3 is available in many languages. https://www.selleckchem.com/products/Zileuton.html However, there is little evidence of the psychometric properties of the Spanish version and using nationally-representative samples.

This study evaluates the reliability and factor solution of the Spanish version of the ASQ-3 (18- to 54-month questionnaires) in a large, representative sample of Uruguayan children. Besides, it explores the association of ASQ-3 scores with sociodemographic characteristics.

Participants were 4016 main caregivers selected randomly across the country who completed the ASQ-3 for their children. All participants responded to the ASQ-3 and a sociodemographic questionnaire within the context of a government-run survey of child development.

Most versions of the ASQ-3 in Spanish have acceptable-to-good psychometric properties, supporting the 5-factor-solution. Personal-Social and, to a lesser extent, Problem-solving scores were the subscales that showed more suboptimal internal consistency coefficients. Scores showed higher ceiling effects than the original US sample but varied across domains, with Gross Motor showing the highest pattern. Sex and socioeconomic status are associated with scores of most age-versions and subscales of the ASQ-3.

In general, results support the reliability and dimensionality of ASQ-3 scores, but psychometric properties varied across age-version and domains. Overall, earlier versions presented less precision, while the Personal-social domain showed reduced reliability in most age-versions.

Besides its nutritional value, it is a good source of chitinase, an enzyme with excellent biological and catalytic properties for many industrial applications. In the present study, a putative chitinase-encoding cDNA was synthesized from mRNA from F. merguiensis hepatopancreas tissue. Subsequently, the corresponding cDNA was cloned, sequenced and functionally expressed in Escherichia coli, and the recombinant F. merguiensis chitinase (rFmCHI) was purified by His-tag affinity chromatography. The bioinformatics analysis of aminoacid sequence of rFmCHI displayed a cannonical multidomain architecture in chitinases which belongs to glycoside hydrolase family 18 (GH18 chitinase). Biochemical characterization revealed rFmCHI as a monomeric enzyme of molecular weight 52 kDa with maximum activity at 40 °C and pH 6.0 Moreover, the recombinant enzyme is also stable up to 60 °C, and in the pH range 5.0-8.0. Steady-state kinetic studies for colloidal chitin revealed KM, Vmax and kcat values of 78.18 μM, 0.07261 μM. min-1 and 43.37 s-1, respectively. Overall, our results aim to demonstrate the potential of rFmCHI as suitable catalyst for bioconversion of chitin waste.Adsorption of therapeutic proteins to material surfaces can be a pivotal issue in drug development, especially for low concentration products. Surfactants are used to limit adsorption losses. For each formulation component, surface adsorption is the result of a combination of its diffusion and surface adsorption rates. The latter are difficult to measure accurately because a depletion layer forms rapidly in the bulk solution above a bare surface, slowing down adsorption. Adapting flow conditions and local surface chemistry, we are able to minimize depletion limitations and measure apparent adsorption rate constants of three monoclonal antibodies, other proteins and surfactants with a hydrophobic surface. We show that surface adsorption rates scale with the molecular mass of the molecule, with polysorbates therefore showing thousand times slower rates than antibodies. Moreover, we observed that the desorption dynamic of polysorbates from a given hydrophobic surface depends on surface coverage, whereas this is not the case for Poloxamer 188. These novel contributions to surface adsorption dynamics enable a new perspective on the evaluation of drug surface compatibility and can, together with diffusion rates, be used to predict the protective potential of surfactants in given conditions.Although the biomedical sciences have achieved tremendous success in developing novel approaches to managing prostate cancer, this disease remains one of the major health concerns among men worldwide. Liposomal formulations of single drugs have shown promising results in cancer treatment; however, the use of multi drugs has shown a better therapeutic index than individual drugs. The identification of cancer-specific receptors has added value to design targeted drug delivering nanocarriers. We have developed genistein and plumbagin co-encapsulating liposomes (∼120 nm) with PSMA specific antibodies to target prostate cancer cells selectively in this work. These liposomes showed >90 % decrease in PSMA expressing prostate cancer cell proliferation without any appreciable toxicity to healthy cells and human red blood cells. Release of plumbagin and genistein was found to decrease the expression of PI3/AKT3 signaling proteins and Glut-1 receptors (inhibited glucose uptake and metabolism), respectively. The decrease in migration potential of cells and induced apoptosis established the observed anti-proliferative effect in prostate cancer cell lines.
