Anomalous origin of pulmonary branches from the ascending aorta. A report of five cases and review of the literature.

J Cardiol Cases 2015 Jan 29;11(1):1-6. Epub 2014 Oct 29.

Pediatric Cardiology Surgery Department, Instituto Nacional de Cardiología "Ignacio Chávez," Mexico City, Mexico.

The anomalous origin of pulmonary branches is a rare entity where, either the right or the left pulmonary arteries arise from the ascending aorta and where the aortic and pulmonary valves are separated. Clinical manifestations usually appear in the infant or, more rarely, in the newborn and include respiratory distress or congestive heart failure due to increased pulmonary resistance.The survival rate in an Indian series was 94% with the death of one patient from Fallot tetralogy.

Repurposing Drugs Based on Evolutionary Relationships Between Targets of Approved Drugs and Proteins of Interest.

Methods Mol Biol 2019 ;1903:45-59

Molecular Biophysics Unit, Indian Institute of Science, Bangalore, Karnataka, India.

Drug repurposing has garnered much interest as an effective method for drug development among biopharmaceutical companies. The availability of information on complete sequences of genomes and their associated biological data, genotype-phenotype-disease relationships, and properties of small molecules offers opportunities to explore the repurpose-able potential of existing pharmacopoeia. This method gains further importance, especially, in the context of development of drugs against infectious diseases, some of which pose serious complications due to emergence of drug-resistant pathogens.

National Center for Atmospheric Research, Climate and Global Dynamics Laboratory, 1850 Table Mesa Drive, Boulder, CO 80305, USA.

The mechanisms driving glacial-interglacial changes in the climate of the Indo-Pacific warm pool are poorly understood. Here, we address this question by combining paleoclimate proxies with model simulations of the Last Glacial Maximum climate. We find evidence of two mechanisms explaining key patterns of ocean cooling and rainfall change interpreted from proxy data. Read More

Injectable Biomimetic Hydrogels as Tools for Efficient T Cell Expansion and Delivery.

Front Immunol 2018 28;9:2798. Epub 2018 Nov 28.

Department of Tumor Immunology, Oncode Institute, Radboud Institute for Molecular Life Sciences, Radboud University Medical Center, Nijmegen, Netherlands.

Biomaterial-based scaffolds are promising tools for controlled immunomodulation. They can be applied as three dimensional (3D) culture systems , whereas they may be used to dictate cellular localization and exert spatiotemporal control over cues presented to the immune system. As such, scaffolds can be exploited to enhance the efficacy of cancer immunotherapies such as adoptive T cell transfer, in which localization and persistence of tumor-specific T cells dictates treatment outcome.
