Background: Insulinoma is a disorder affecting one in 100,000 of the general population. The clinical profile of insulinomas among Indian patients has not been characterized. Aim of the study: To study the clinical characteristics, biochemical and radiological parameters and treatment aspects of adult patients with insulinomas. Methodology: A retrospective analysis of 18 patients with insulinoma who were treated from 1992 to 2004

We transfected siRNA targeting HIV-1 promoter region into a cell line productively infected with HIV-1. ChIP analysis revealed that the RNA duplex induced transcriptional gene silencing and enrichment of Ago1, H3K9me2, and HDAC1 in HIV promoter region to form heterochromatin structure. The data indicates RNA duplex induces the latent phase of HIV infection, since the chromosome formation is very similar to the state of HIV latently infected cell lines

An inadequate transfer of oxygen can lead to rapid changes in cell physiology, metabolism, and cell death. In this work, the KLa is evaluated in a Taylor vortex flow bioreactor and a mass transfer correlation is proposed. The experimental conditions employed were: rotational Reynolds number between 244 and 2928, airflow rates varying from 80 mL.min-1 to 550 mL.min-1 and used culture medium DMEM.

Three proteases involved in the contact phase of vertebrate blood coagulation were searched in genomes of amphibians, birds and mammals. Several data sources were used during this bioinformatics analysis. Our survey confirmed that the vertebrate contact phase has occurred by way of a series of gene duplications during the course of several hundred million years of evolution, beginning with the appearance of fXII and a PK-fXI predecessor in amphibians.

In this work, a pressurized bioreactor was used for Y. lipolytica batch cultivation under increased air pressure from 1 bar to 6 bar. Cell growth was strongly enhanced by the pressure rise. The increase of oxygen availability caused the induction of the antioxidant enzyme SOD. The pre-growth of Y. lipolytica under increased pressure conditions did not affect the lipase production ability of the cells.

Pichia pastoris processes for heterolougous protein expression are typically run in three phases: a batch phase, an exponential feeding fed-batch phase and a long oxygen transfer limitation (OTL) phase. The final protein titre is often limited by the oxygen availability in the OTL phase. Here a direct adaptive controller is designed for the OTL phase. The controller was validated in pilot P. pastoris cultivations expressing a single chain antibody fragment (ScFv). This work shows that the propos

Image processing is a very relevant area of computer science with applications in many domains. Quantitative analysis and interpretation of digitized images is currently an important tool in several scientific domains. The aim of the present work is the development of shape discrimination and size classification algorithms for liquid drops in monochromatic digitized frames.

Using primary cells for RNAi based applications such as target identification or – validation, requires a highly efficient transfection technology in combination with a reliable and robust automation system. To accomplish these requirements we integrated the amaxa 96-well Shuttle® in a Tecan Freedom EVO® cell transfection workstation which is based on Tecan’s Freedom EVO® liquid handling platform and include all the necessary components and features for unattended cell transfection.
