Missing genotype imputation in non-model species using self-organizing maps.

Current methodologies of genome-wide single-nucleotide polymorphism (SNP) genotyping produce large amounts of missing data that may affect statistical inference and bias the outcome of experiments. Genotype imputation is routinely used in well-studied species to buffer the impact in downstream analysis, and several algorithms are available to fill in missing genotypes. The lack of reference haplotype panels precludes the use of these methods in genomic studies on non-model organisms.

Diaphragmatic hernia after radiofrequency ablation of liver metastases: a case report and review of the literature.

A diaphragmatic hernia is the protrusion of abdominal tissues into the thoracic cavity secondary to a defect in the diaphragm. Reviewing the literature, we found only 44 references to diaphragmatic hernia secondary to percutaneous radiofrequency treatment. The vast majority of these cases were secondary to the treatment of hepatocellular carcinoma in segments V and VIII.

Alternative forms of portal vein revascularization in liver transplant recipients with complex portal vein thrombosis.

Background & Aims: Complex portal vein thrombosis (PVT) is a challenge in liver transplantation (LT). Extra-anatomical approaches to portal revascularization, including renoportal (RPA), left gastric vein (LGA), pericholedochal vein (PCA), and cavoportal (CPA) anastomoses, have been described in case reports and series. The RP4LT Collaborative was created to record cases of alternative portal revascularization performed for complex PVT.

Dropping mortality by increasing connectivity in plant epidemics.

Pathogen introduction in plant communities can cause serious impacts and biodiversity losses that may take a long time to manage and restore. Effective control of epidemic spreading in the wild is a problem of paramount importance because of its implications in conservation and potential economic losses. Understanding the mechanisms that hinder pathogen propagation is, therefore, crucial.
