Gradual Domain Adaptation via Normalizing Flows.

Standard domain adaptation methods do not work well when a large gap exists between the source and target domains. Gradual domain adaptation is one of the approaches used to address the problem. It involves leveraging the intermediate domain, which gradually shifts from the source domain to the target domain.

Treatment Strategies for Non-Small-Cell Lung Cancer with Comorbid Respiratory Disease; Interstitial Pneumonia, Chronic Obstructive Pulmonary Disease, and Tuberculosis.

Non-small cell lung cancer (NSCLC) patients are often complicated by other respiratory diseases, including interstitial pneumonia (IP), chronic obstructive pulmonary disease (COPD), and pulmonary tuberculosis (TB), and the management of which can be problematic. NSCLC patients with IP sometimes develop fatal acute exacerbation induced by pharmacotherapy, and the establishment of a safe treatment strategy is desirable. For advanced NSCLC with IP, carboplatin plus nanoparticle albumin-bound paclitaxel is a relatively safe and effective first-line treatment option.

Inhibitor as a Treatment Option for Non-Small-Cell Lung Cancer with Comorbid Interstitial Pneumonia.

Non-small-cell lung cancer (NSCLC) with comorbid interstitial pneumonia (IP) is a population with limited treatment options and a poor prognosis. Patients with comorbid IP are at high risk of developing fatal drug-induced pneumonitis, and data on the safety and efficacy of molecularly targeted therapies are lacking. mutations have been frequently detected in patients with NSCLC with comorbid IP.

Cost-effective framework for gradual domain adaptation with multifidelity.

In domain adaptation, when there is a large distance between the source and target domains, the prediction performance will degrade. Gradual domain adaptation is one of the solutions to such an issue, assuming that we have access to intermediate domains, which shift gradually from the source to the target domain. In previous works, it was assumed that the number of samples in the intermediate domains was sufficiently large; hence, self-training was possible without the need for labeled data.

How does a small molecule bind at a cryptic binding site?

Protein-protein interactions (PPIs) are ubiquitous biomolecular processes that are central to virtually all aspects of cellular function. Identifying small molecules that modulate specific disease-related PPIs is a strategy with enormous promise for drug discovery. The design of drugs to disrupt PPIs is challenging, however, because many potential drug-binding sites at PPI interfaces are "cryptic": When unoccupied by a ligand, cryptic sites are often flat and featureless, and thus not readily recognizable in crystal structures, with the geometric and chemical characteristics of typical small-molecule binding sites only emerging upon ligand binding.

Horizontally transmitted parasitoid killing factor shapes insect defense to parasitoids.

Interkingdom competition occurs between hymenopteran parasitoids and insect viruses sharing the same insect hosts. It has been assumed that parasitoid larvae die with the death of the infected host or as result of competition for host resources. Here we describe a gene family, (), that encodes proteins toxic to parasitoids of the Microgastrinae group and determines parasitism success.

Association Between the Swallowing Reflex and the Incidence of Aspiration Pneumonia in Patients With Dysphagia Admitted to Long-term Care Wards: A Prospective Cohort Study of 60 Days.

Objective: To investigate the association between the Simple Swallowing Provocation Test (SSPT) and the incidence of aspiration pneumonia in patients with dysphagia in long-term care (LTC) wards.

Design: The study design was a prospective cohort study. Participants were followed for 60 days from admission.

The architecture of EGFR's basal complexes reveals autoinhibition mechanisms in dimers and oligomers.

Our current understanding of epidermal growth factor receptor (EGFR) autoinhibition is based on X-ray structural data of monomer and dimer receptor fragments and does not explain how mutations achieve ligand-independent phosphorylation. Using a repertoire of imaging technologies and simulations we reveal an extracellular head-to-head interaction through which ligand-free receptor polymer chains of various lengths assemble. The architecture of the head-to-head interaction prevents kinase-mediated dimerisation.

An ascovirus isolated from Spodoptera litura (Noctuidae: Lepidoptera) transmitted by the generalist endoparasitoid Meteorus pulchricornis (Braconidae: Hymenoptera).

The family Ascoviridae is a recently described virus family whose members are transmitted by parasitoids and cause chronic and lethal infections in lepidopteran insects. Little is known about the biology and ecology of ascoviruses, and few isolates have been found outside the United States. We report here the isolation of a new ascovirus variant from Spodoptera litura in Japan.

One Electron-Initiated Two-Electron Oxidation of Water by Aluminum Porphyrins with Earth's Most Abundant Metal.

We report herein a new molecular catalyst for efficient water splitting, aluminum porphyrins (tetra-methylpyridiniumylporphyrinatealuminum: AlTMPyP), containing earth's most abundant metal as the central ion. One-electron oxidation of the aluminum porphyrin initiates the two-electron oxidation of water to form hydrogen peroxide as the primary reaction product with the lowest known overpotential (97 mV). The aluminum-peroxo complex was detected by a cold-spray ionization mass-spectrometry in high-resolution MS (HRMS) mode and the structure of the intermediate species was further confirmed using laser Raman spectroscopy, indicating the hydroperoxy complex of AlTMPyP to be the key intermediate in the reaction.

Genotype Specification Language.

We describe here the Genotype Specification Language (GSL), a language that facilitates the rapid design of large and complex DNA constructs used to engineer genomes. The GSL compiler implements a high-level language based on traditional genetic notation, as well as a set of low-level DNA manipulation primitives. The language allows facile incorporation of parts from a library of cloned DNA constructs and from the "natural" library of parts in fully sequenced and annotated genomes.

Paradoxical suppression of small RNA activity at high Hfq concentrations due to random-order binding.

Small RNAs (sRNAs) are important regulators of gene expression during bacterial stress and pathogenesis. sRNAs act by forming duplexes with mRNAs to alter their translation and degradation. In some bacteria, duplex formation is mediated by the Hfq protein, which can bind the sRNA and mRNA in each pair in a random order.

Modulating the frequency and bias of stochastic switching to control phenotypic variation.

Mechanisms that control cell-to-cell variation in gene expression ('phenotypic variation') can determine a population's growth rate, robustness, adaptability and capacity for complex behaviours. Here we describe a general strategy (termed FABMOS) for tuning the phenotypic variation and mean expression of cell populations by modulating the frequency and bias of stochastic transitions between 'OFF' and 'ON' expression states of a genetic switch. We validated the strategy experimentally using a synthetic fim switch in Escherichia coli.

Discovery of 6-phenylpyrimido[4,5-b][1,4]oxazines as potent and selective acyl CoA:diacylglycerol acyltransferase 1 (DGAT1) inhibitors with in vivo efficacy in rodents.

The discovery and optimization of a series of acyl CoA:diacylglycerol acyltransferase 1 (DGAT1) inhibitors based on a pyrimido[4,5-b][1,4]oxazine scaffold is described. The SAR of a moderately potent HTS hit was investigated resulting in the discovery of phenylcyclohexylacetic acid 1, which displayed good DGAT1 inhibitory activity, selectivity, and PK properties. During preclinical toxicity studies a metabolite of 1 was observed that was responsible for elevating the levels of liver enzymes ALT and AST.

Bioluminescence of a firefly pupa: involvement of a luciferase isotype in the dim glow of pupae and eggs in the Japanese firefly, Luciola lateralis.

We isolated cDNA for a luciferase isotype, LlLuc2, from the ovary of the Japanese firefly, Luciola lateralis. The gene product LlLuc2 showed 59% amino acid identity with LlLuc1, which had been isolated from the adult L. lateralis lantern.

Efficient health information management systems using wireless communications technology to aid disaster victims.

Japan is an earthquake-prone country, and disasters have a devastating effect on the lives of residents in stricken areas. Shelters can be constructed in order to secure the physical safety of residents, but there are no such provisions for the shock of experiencing a disaster, losing property and friends, and transitioning to an unfamiliar life in a shelter, all of which can lead to mental disorders. Caretakers such as medical doctors and nurses who are dispatched to disaster sites also face difficulties in the disruption of communications and transportation, thus a system able to secure efficient health management in those facilities is also required.

Discovery of pyrrolopyridazines as novel DGAT1 inhibitors.

A new structural class of DGAT1 inhibitors was discovered and the structure-activity relationship was explored. The pyrrolotriazine core of the original lead molecule was changed to a pyrrolopyridazine core providing an increase in potency. Further exploration resulted in optimization of the propyl group at C7 and the discovery that the ester at C6 could be replaced by five-membered heterocyclic rings.

Heterogeneous levels of oxidative phosphorylation enzymes in rat adrenal glands.

Mitochondria are organelles that produce ATP and reactive oxygen species, which are thought to be responsible for a decline in physiological function with aging. In this study, we morphologically and biochemically examined mitochondria in the rat adrenal gland. Immunohistochemistry showed that the rank order for intensity of immunolabelling for complex IV was zona reticularis > zona fasciculata >> adrenal medulla, whereas for complex V α and β subunits, it was zona fasciculata > zona reticularis and adrenal medulla.

Continuous monitoring of changes in blood volume and limb volume during lower body negative pressure.

Lower body negative pressure (LBNP) induces venous pooling in the legs and a decrease of blood volume (BV). The present study was designed to investigate the dynamic changes in BV and limb volume during LBNP. We made continuous measurements of blood density (h) during LBNP at two different levels (-15 and -30 mmHg) in eight healthy male volunteers.

Distribution and metabolism of dihomo-gamma-linolenic acid (DGLA, 20:3n-6) by oral supplementation in rats.

We compared the dietary effects of dihomo-gamma-linolenic acid (DGLA) contained in the DGLA oil produced by a fungus with gamma-linolenic acid (GLA) on the fatty acid composition. Wistar rats were fed with three kinds of oil for two weeks as follows: (i) control group: corn oil; (ii) GLA group: borage oil; (iii) DGLA group: DGLA oil/safflower oil = 55:45. The DGLA concentrations in the liver, serum, and brain of the DGLA group were higher than those of the GLA oil group.
