On the completeness of the semigraphoid axioms for deriving arbitrary from saturated conditional independence statements

Marc Gyssens, Mathias Niepert, Dirk Van Gucht, M. Gyssens, more

Information Processing Letters > 2014 > 114 > 11 > 628-633

Conditional independence (CI) statements occur in several areas of computer science and artificial intelligence, e.g., as embedded multivalued dependencies in database theory, disjunctive association rules in data mining, and probabilistic CI statements in probability theory. Although, syntactically, such constraints can always be represented in the form I(A,B|C), with A, B, and C subsets of some...

Searching fee and non-fee toxicology information resources: an overview of selected databases

Larry L. Wright

Toxicology > 2001 > 157 > 1-2 > 89 - 110

Toxicology profiles organize information by broad subjects, the first of which affirms identity of the agent studied. Studies here show two non-fee databases (ChemFinder and ChemIDplus) verify the identity of compounds with high efficiency (63% and 73% respectively) with the fee-based Chemical Abstracts Registry file serving well to fill data gaps (100%). Continued searching proceeds using knowledge...

Rethinking databases: The fib project for a connected data repository

David Fernández‐Ordóñez, Miguel Fernández Ruiz, Nikola Tošić, Roman Wan‐Wendner, more

Structural Concrete > 24 > 4 > 4480 - 4491

The need for reliable test data to verify scientific theories together with the necessity to calibrate code‐oriented expressions and their level of safety have pushed researchers to develop test databases. Such databases collect the work of multiple independent scientific initiatives compiling experimental evidences on similar test configurations but with different parameters such as geometry, size...

Cardiac electronic implantable devices: A call for a new coding system

Damià Pereferrer, Roger Villuendas, Victor Bazan, Axel Sarrias, more

Pacing and Clinical Electrophysiology > 46 > 8 > 939 - 941

Over the last decades, cardiac electronic implantable devices (CEID) have incorporated a myriad of technological capabilities that are not conveniently inferred by using the conventional ICHD and NBG coding systems. We propose a new coding system (i.e., the C‐ARL‐A coding system) aimed at overcoming this important limitation.

A global review demonstrating the importance of nocturnal pollinators for crop plants

Max N. Buxton, Anne C. Gaskett, Janice M. Lord, David E. Pattemore

Journal of Applied Ecology > 59 > 12 > 2890 - 2901

Pollinating insects are critical to ecosystem stability and food security. Concerns about the impact of insect declines have therefore seen increased research on the role of wild pollinators in cropping systems. However, this research has predominantly focused on diurnal pollinators such as bees and flies, leaving the role of nocturnal pollinators poorly understood in comparison. Here, we review...

Association Between Antiosteoporotic Drugs and Risk of Acute Kidney Injury: A Cross‐Sectional Study Using Disproportional Analysis and a Pharmacovigilance Database

Satoru Mitsuboshi, Ryohei Kaseda, Ichiei Narita

The Journal of Clinical Pharmacology > 62 > 11 > 1419 - 1425

The number of fractures related to osteoporosis is expected to increase. Therefore, clarifying the risk of acute kidney injury (AKI) associated with each type of antiosteoporotic drug may avoid discontinuation of osteoporosis pharmacotherapy due to onset of AKI. This cross‐sectional study using disproportional analysis and a pharmacovigilance database assessed the risk of AKI with various antiosteoporotic...

Integrating experience with databases, bioinformatics, and wet lab exercises for students in an introductory genetics course

David J. Carroll

Biochemistry and Molecular Biology Education > 50 > 5 > 457 - 459

Students often have no exposure to the incredible amount of genomic and proteomic data that is freely and easily accessible online. Becoming familiar with these resources, and seeing how they could be applied to a specific research question, is a prerequisite for students to apply them to their own scientific development. Many students have to “see it” and “do it” before they “get it.” This paper...

Redefining the coenzyme A transferase superfamily with a large set of manually annotated proteins

Timothy J. Hackmann

Protein Science > 31 > 4 > 864 - 881

The coenzyme A (CoA) transferases are a superfamily of proteins central to the metabolism of acetyl‐CoA and other CoA thioesters. They are diverse group, catalyzing over a 100 biochemical reactions and spanning all three domains of life. A deeply rooted idea, proposed two decades ago, is these enzymes fall into three families (I, II, and III). Here we find they fall into different families, which...

Pigment Cell & Melanoma Research > 34 > 6 > 1049 - 1061

Acral lentiginous melanoma (ALM) is a rare histological subtype of cutaneous malignant melanoma that typically presents on the palms and soles. To characterize the demographic and treatment characteristics of ALM, we used the National Cancer Database (NCDB) to describe a large multi‐institutional cohort of ALM patients, consisting of 4,796 ALM patients from 2004 to 2015. ALM was more likely to be...

Journal of Integrative Plant Biology > 63 > 11 > 1888 - 1905

To understand and engineer plant metabolism, we need a comprehensive and accurate annotation of all metabolic information across plant species. As a step towards this goal, we generated genome‐scale metabolic pathway databases of 126 algal and plant genomes, ranging from model organisms to crops to medicinal plants (https://plantcyc.org). Of these, 104 have not been reported before. We systematically...

Chemoinformatic Analysis of Isothiocyanates: Their Impact in Nature and Medicine

Araceli Guerrero‐Alonso, Mayra Antunez‐Mojica, José L. Medina‐Franco

Molecular Informatics > 40 > 11 > n/a - n/a

Isothiocyanates (ITCs) have a significant impact on food and natural product chemistry. Several dietary components and food chemicals contain the isothiocyanate moiety. In addition, many ITCs interact with macromolecules of biological relevance, making these compounds relevant for potential therapeutic applications and disease prevention. However, there is a lack of systematic analysis of ITCs in...
