Machine-learning models are superior to severity scoring systems for the prediction of the mortality of critically ill patients in a tertiary medical center.

Background: Intensive care unit (ICU) mortality prediction helps to guide therapeutic decision making for critically ill patients. Several scoring systems based on statistical techniques have been developed for this purpose. In this study, we developed a machine-learning model to predict patient mortality in the very early stage of ICU admission.

mRNA expression and functional analysis of chicken IFIT5 after infected with Newcastle disease virus.

Innate immunity is the first line against the invasion of pathogenic microorganisms. Over the past several years, the antiviral activity and mechanisms of the IFIT5 gene have been confirmed in mammals. However, more information is needed on the role of IFIT5 in response to viral infection in chickens.

Polymorphism in , and genes in different colored feather chickens.

Coat color genetics successfully adapted and applied to different animal species, which provides a good demonstration of the concept of comparative genetics. In this study, we sequenced 945 bp fragments of () gene, 421 bp fragments of exon 1 of () gene and 266 bp fragments of exon 3 of () gene for 250 individuals with five plumage color patterns. We detected a total of three SNPs (T398A, T637C, and G920C) in and built six haplotypes (H1-H6) based on the three SNPs.

[Curative effects of extrusive and Fogarty balloon catheter embolectomy in acute femoral vein thrombosis: experiment with rabbits].

Objective: To compare the influence extrusive and Fogarty balloon catheter embolectomy on the patency rate of bloodstream and the damage of the wall of vein in acute femoral vein thrombosis.

Methods: Eighty rabbits were randomly divided into 4 groups: Group A (n = 25) undergoing ligation of unilateral femoral to establish acute femoral vein thrombosis model and treated by extrusion of the hind leg muscles 24 h after the operation, Group B (n = 25) treated by Fogarty balloon catheter embolectomy 24 h after establishment of the thrombosis model, Group C (n = 25) undergoing sham operation, and Group D (n = 5) as normal controls.7, 14, and 28 days after the treatment digital subtraction angiography (DSA) was conducted to observe the patency rate of the vessel.
