Utility of Repeat Latent Tuberculosis Testing with QuantiFERON‐TB Gold test in Psoriasis Patients Treated with TNF‐α inhibitors at a Single U.S. Institution
Abstract Risk of latent tuberculosis infection (LTBI) reactivation in psoriasis patients treated with TNF‐α inhibitors (TNFIs) is well‐known1. Thus, some organizations, including the National Psoriasis Foundation, recommend serial LTBI testing in patients receiving long‐term TNFI treatment2. Additionally, annual LTBI screening has been incorporated into Medicare Merit‐Based Incentive Payment Systems (MIPS) quality measures and will impact physician reimbursement3.

AKT‐dependent hyperproliferation of keratinocytes in familial hidradenitis suppurativa with NCSTN mutation: A potential role of defective miR‐100‐5p
Abstract Hidradenitis suppurativa (HS), also known as acne inversa, is a chronic inflammatory skin disorder affecting apocrine gland‐bearing areas of the body.1 Although the precise pathogenesis of HS is unclear, genetic mutation may one important factor. Recently, loss‐of‐function mutations of nicastrin (NCSTN), a subunit of γ‐secretase, are detected in some familial HS patients.2,3 In 2016, we reported that the expression of both AKT and its activated form phosphorylated‐AKT (p‐AKT) is up‐regulated...

HiLDA: a statistical approach to investigate differences in mutational signatures
We propose a hierarchical latent Dirichlet allocation model (HiLDA) for characterizing somatic mutation data in cancer. The method allows us to infer mutational patterns and their relative frequencies in a set of tumor mutational catalogs and to compare the estimated frequencies between tumor sets. We apply our method to two datasets, one containing somatic mutations in colon cancer by the time of occurrence, before or after tumor initiation, and the second containing somatic mutations in esophageal...

Cyclodipeptides from Pseudomonas aeruginosa modulate the maize (Zea mays L.) root system and promote S6 ribosomal protein kinase activation
Background Pseudomonas aeruginosa is an opportunistic and pathogenic bacterium with the ability to produce cyclodipeptides (CDPs), which belong to a large family of molecules with important biological activities. Excessive amounts of CDPs produced by Pseudomonas strains can activate an auxin response in Arabidopsis thaliana and promote plant growth. Target of rapamycin (TOR) is an evolutionarily conserved eukaryotic protein kinase that coordinates cell growth and metabolic processes in response...

Testing the function of dromaeosaurid (Dinosauria, Theropoda) ‘sickle claws’ through musculoskeletal modelling and optimization
Dromaeosaurids were a clade of bird-like, carnivorous dinosaurs that are well known for their characteristic morphology of pedal digit II, which bore an enlarged, sickle-shaped claw and permitted an extreme range of flexion–extension. Proposed functions for the claw often revolve around predation, but the exact manner of use varies widely. Musculoskeletal modelling provides an avenue to quantitatively investigate the biomechanics of this enigmatic system, and thereby test different behavioural hypotheses....

Comparative transcriptomics reveals the difference in early endosperm development between maize with different amylose contents
In seeds, the endosperm is a crucial organ that plays vital roles in supporting embryo development and determining seed weight and quality. Starch is the predominant storage carbohydrate of the endosperm and accounts for ∼70% of the mature maize kernel weight. Nonetheless, because starch biosynthesis is a complex process that is orchestrated by multiple enzymes, the gene regulatory networks of starch biosynthesis, particularly amylose and amylopectin biosynthesis, have not been fully elucidated....

Endogenous testosterone correlates with parochial altruism in relation to costly punishment in different social settings
Testosterone plays a key role in shaping human social behavior. Recent findings have linked testosterone to altruistic behavior in economic decision tasks depending on group membership and intergroup competition. The preferential treatment of ingroup members, while aggression and discrimination is directed towards outgroup members, has been referred to as parochial altruism. Here we investigated in two consecutive studies, whether testosterone is associated with parochial altruism depending on individual...

Determination of nucleotide and enzyme degradation in haddock (Melanogrammus aeglefinus) and herring (Clupea harengus) after high pressure processing
Background The degradation of nucleotides and their enzymes had been widely used to evaluate fish freshness. Immediately after fish death, adenosine triphosphate (ATP) degrades into inosine-5-monophosphate (IMP) via adenosine-5-diphosphate (ADP) and adenosine-5-monophosphate (AMP). IMP degradation continues to produce inosine (ino) and hypoxanthine (Hx) and further deteriorates the fish by producing xanthine and uric acid. The dephosphorylation of IMP to Ino is carried out by the enzyme 5′-nucleotidase...
