Heterologous Expression of an Insecticidal Peptide Obtained from the Transcriptome of the Colombian Spider .

Spider venoms are composed, among other substances, of peptide toxins whose selectivity for certain physiological targets has made them powerful tools for applications such as bioinsecticides, analgesics, antiarrhythmics, antibacterials, antifungals and antimalarials, among others. Bioinsecticides are an environmentally friendly alternative to conventional agrochemicals. In this paper, the primary structure of an insecticidal peptide was obtained from the venom gland transcriptome of the ctenid spider (Transcript ID PhdNtxNav24).

Effectiveness of social responsibility marketing in young millennials - Generation Y: analysis of three cases for brand positioning.

The aim of this study was to investigate how social responsibility marketing campaigns can be effective in branding for young millennials. An empirical model was applied in three specific cases of cause marketing targeting Generation Y. A total sample of 547 young people was obtained, and the data were analysed through the structural equation methodology using PLS data technical analysis.

Magnetic resonance elastography to quantify liver disease severity in autosomal recessive polycystic kidney disease.

Objectives: To evaluate whether liver and spleen magnetic resonance elastography (MRE) can measure the severity of congenital hepatic fibrosis (CHF) and portal hypertension (pHTN) in individuals with autosomal recessive polycystic kidney disease (ARPKD), and to examine correlations between liver MRE and ultrasound (US) elastography.

Methods: Cross-sectional study of nine individuals with ARPKD and 14 healthy controls. MRE was performed to measure mean liver and spleen stiffness (kPa); US elastography was performed to measure point shear wave speed (SWS) in both liver lobes.

Effects of preconditioning the rhizosphere of different plant species on biotic methane oxidation kinetics.

The rhizosphere is known as the most active biogeochemical layer of the soil. Therefore, it could be a beneficial environment for biotic methane oxidation. The aim of this study was to document - by means of batch incubation tests - the kinetics of CH4 oxidation in rhizosphere soils that were previously exposed to methane.

[Applying the clustering technique for characterising maintenance outsourcing].

Objective: Using clustering techniques for characterising companies providing health institutions with maintenance services.

Methods: The study analysed seven pilot areas' equipment inventory (264 medical devices). Clustering techniques were applied using 26 variables.
