Configuration sampling in multi-component multi-sublattice systems enabled by ab Initio Configuration Sampling Toolkit (abICS)
Simulation of the intermediate levels of disorder found in multi-component
multi-sublattice systems in various functional materials is a challenging
issue, even for state-of-the-art methodologies based on first-principles
calculation. Here, we introduce our open-source package ab Initio Configuration
Sampling Toolkit (abICS), which combines high-throughput first-principles
calculations, machine learning, and parallel extended ensemble sampling in an
active learning setting to enable such simulations. The theoretical background
is reviewed in some detail followed by brief notes on usage of the software. In
addition, our recent applications of abICS to multi-component ionic systems and
their interfaces for energy applications are reviewed as demonstration of the
power of this approach.Comment: 25 pages, 6 figure

Monivammapotilaan kivunhoito
TÀmÀn opinnÀytetyön tarkoituksena oli kartoittaa monivammapotilaan kivunhoitoa ennen sairaalaan tuloa, sairaalassa ja kotona systemaattista kirjallisuuskatsausta soveltaen. Tavoitteena on edistÀÀ monivammapotilaan kivunhoitoa. OpinnÀytetyöhön valikoitui analysoitavaksi 38 (=n) julkaisua.
Monivammapotilaan kivunhoito vaatii moniammatillista osaamista ja yhteistyötÀ. Kivunhoidon oleellisena osana on kivun arviointi. Kipua voidaan arvioida erilaisin mittarein, kuten sanallinen asteikko (VRS), numeroasteikko (NRS) ja visuaalianalogiasteikko (VAS). Potilaan ollessa tajuton, kivunarviointi muuttuu haasteellisemmaksi, sillÀ silloin mittareita ei voida kÀyttÀÀ.
Monivammapotilaan kipua hoidetaan pÀÀsÀÀntöisesti lÀÀkkeillÀ. KeskeisimpiÀ lÀÀkkeitÀ ovat tulehduskipulÀÀkkeet, parasetamoli ja opioidit. LÀÀkkeettömiÀ kivunhoitomuotoja kuten asentohoito, fysikaaliset hoitomuodot, hengitysharjoitukset, musiikin kuuntelu, rentoutumis- ja mielikuvaharjoitukset, kÀytetÀÀn myös, mutta ne ovat tehokkaampia yhdistettynÀ lÀÀkkeelliseen kivunhoitoon. LÀÀkehoito koostuu monen lÀÀkeryhmÀn yhdistelmistÀ eli multimodaalisesta kivunhoidosta. Puudutteet ovat keskeinen osa monivammapotilaan kivunhoitoa, sillÀ ne vÀhentÀvÀt huomattavasti opioidien kÀyttöÀ. Kivunhoito on tasapainoilua potilaan kivuttomuuden ja kivunhoidon haittavaikutuksien vÀlillÀ. Potilaan kivunhoito jatkuu koko hoidon ajan, myös kotiutumisen jÀlkeen.
Kivunhoito on potilaan oikeus eikĂ€ ole olemassa mitÀÀn pĂ€tevÀÀ syytĂ€ jĂ€ttÀÀ kipua hoitamatta. Monivammapotilaat ovat todella kivuliaita, joten kivun hoidon tutkiminen ja kehittĂ€minen on tĂ€rkeÀÀ. Tehokkaalla kivunhoidolla voidaan ehkĂ€istĂ€ kivun kroonistumista.The purpose of this thesis is to improve multi-trauma patients pain management before coming to a hospital, in hospital and at home by using a systematic literature review. The aim is to improve multi-trauma patientâs pain management. There was 38(=n) publications chosen for this thesis.
The pain management of a multi-trauma patient requires multi-professional expertise and cooperation. An essential part of pain management is assessment of pain. The pain can be assessed with different kind of rating scales for example verbal rating scale (VRS), numeric rating scale (NRS) and visual analog scale (VAS). When patient is being unconscious assessment of pain becomes challenging so the rating scales cannot be used.
The pain of a multi-trauma patient is mainly managed with medicine. The most common medicines are inflammatory drugs, paracetamol and opioids. Drug-free pain management formats such as position management, physical therapies, breathing exercises, listening to music, relaxing and imagination exercises are used but they are more effective combined with medicinal pain management. Medication consist of the combination of different drug groups called multimodal pain management. Regional anesthetics are a key part of the pain management of a multi-trauma patient because regional anesthetics reduce remarkably the use of opioids. Pain management is balancing between painless and side effects pain management. The pain management of the patient goes through the whole care also after discharging from hospital.
Pain management is the patients right and there is no competent reason to not treat the pain. Multi-trauma patients are in a high amount of pain so the study and development of pain management is really important. With efficient pain management you can anticipate chronical pain
Proposal for measuring magnetism with patterned apertures
We propose a magnetic measurement method utilizing a patterned post-sample
aperture in a transmission electron microscope. While utilizing electron
magnetic circular dichroism, the method circumvents previous needs to shape the
electron probe to an electron vortex beam or astigmatic beam. The method can be
implemented in standard scanning transmission electron microscopes by replacing
the spectrometer entrance aperture with a specially shaped aperture, hereafter
called ventilator aperture. The proposed setup is expected to work across the
whole range of beam sizes -- from wide parallel beams down to atomic resolution
magnetic spectrum imaging.Comment: 6 pages, 4 figure
Measurement of brain concentration of FK960 for development of a novel antidementia drug: A PET study in conscious rhesus monkeys
éæȹ性ćŠć€§ćŠéąć»ćŠçł»ç 究ç§This study used PET to measure the time course of the brain concentration of 18F-labeled N-(4-acetyl-1-piperazinyl)-p-fluorobenzamide monohydrate (FK960), a novel antidementia drug, after oral administration to conscious rhesus monkeys. Methods: Three young-adult male rhesus monkeys were tested. FK960 (0.1 mg/kg) containing about 370 MBq of 18F-FK960 was administered orally to each monkey. Dynamic PET images were acquired for 4 h from 5 min after the administration. Arterial blood samples were withdrawn during PET scanning and were analyzed by an automatic well Îł-counter and thin-layer chromatography to determine the time course of authentic 18F-FK960 activity concentration in plasma. FK960 concentrations in brain and plasma were calculated in units of mol/L using the specific activity of FK960 preparations. Results: 18F-FK960 penetrated the blood-brain barrier and underwent perfusion-dependent distribution in the entire brain. Maximal concentrations in the brain and plasma were 1.11 ± 0.30 x 10-7 mol/L (at 3.0 ± 0.6 h after administration) and 4.04 ± 1.29 x 10-7 mol/L (at 2.0 ± 1.1 h after administration), respectively. Conclusion: We succeeded in measuring the FK960 concentration in the brains of conscious monkeys and in plasma after oral administration at a dose of 0.1 mg/kg. The results suggested that this method can measure the FK960 concentration in the human brain, and a potential use of the PET technique in drug development was demonstrated
Extreme deformability of insect cell membranes is governed by phospholipid scrambling
æè«ăźçŽ°èăŻæăăăïŒ --现èèăæăăăăăăżăłăăŻèłȘăçșèŠ--. äșŹéœć€§ćŠăăŹăčăȘăȘăŒăč. 2021-06-09.Organization of dynamic cellular structure is crucial for a variety of cellular functions. In this study, we report that Drosophila and Aedes have highly elastic cell membranes with extremely low membrane tension and high resistance to mechanical stress. In contrast to other eukaryotic cells, phospholipids are symmetrically distributed between the bilayer leaflets of the insect plasma membrane, where phospholipid scramblase (XKR) that disrupts the lipid asymmetry is constitutively active. We also demonstrate that XKR-facilitated phospholipid scrambling promotes the deformability of cell membranes by regulating both actin cortex dynamics and mechanical properties of the phospholipid bilayer. Moreover, XKR-mediated construction of elastic cell membranes is essential for hemocyte circulation in the Drosophila cardiovascular system. Deformation of mammalian cells is also enhanced by the expression of Aedes XKR, and thus phospholipid scrambling may contribute to formation of highly deformable cell membranes in a variety of living eukaryotic cells
A novel method, digital genome scanning detects KRAS gene amplification in gastric cancers: involvement of overexpressed wild-type KRAS in downstream signaling and cancer cell growth
<p>Abstract</p> <p>Background</p> <p>Gastric cancer is the third most common malignancy affecting the general population worldwide. Aberrant activation of KRAS is a key factor in the development of many types of tumor, however, oncogenic mutations of <it>KRAS </it>are infrequent in gastric cancer. We have developed a novel quantitative method of analysis of DNA copy number, termed digital genome scanning (DGS), which is based on the enumeration of short restriction fragments, and does not involve PCR or hybridization. In the current study, we used DGS to survey copy-number alterations in gastric cancer cells.</p> <p>Methods</p> <p>DGS of gastric cancer cell lines was performed using the sequences of 5000 to 15000 restriction fragments. We screened 20 gastric cancer cell lines and 86 primary gastric tumors for <it>KRAS </it>amplification by quantitative PCR, and investigated <it>KRAS </it>amplification at the DNA, mRNA and protein levels by mutational analysis, real-time PCR, immunoblot analysis, GTP-RAS pull-down assay and immunohistochemical analysis. The effect of <it>KRAS </it>knock-down on the activation of p44/42 MAP kinase and AKT and on cell growth were examined by immunoblot and colorimetric assay, respectively.</p> <p>Results</p> <p>DGS analysis of the HSC45 gastric cancer cell line revealed the amplification of a 500-kb region on chromosome 12p12.1, which contains the <it>KRAS </it>gene locus. Amplification of the <it>KRAS </it>locus was detected in 15% (3/20) of gastric cancer cell lines (8â18-fold amplification) and 4.7% (4/86) of primary gastric tumors (8â50-fold amplification). <it>KRAS </it>mutations were identified in two of the three cell lines in which <it>KRAS </it>was amplified, but were not detected in any of the primary tumors. Overexpression of KRAS protein correlated directly with increased <it>KRAS </it>copy number. The level of GTP-bound KRAS was elevated following serum stimulation in cells with amplified wild-type <it>KRAS</it>, but not in cells with amplified mutant <it>KRAS</it>. Knock-down of <it>KRAS </it>in gastric cancer cells that carried amplified wild-type <it>KRAS </it>resulted in the inhibition of cell growth and suppression of p44/42 MAP kinase and AKT activity.</p> <p>Conclusion</p> <p>Our study highlights the utility of DGS for identification of copy-number alterations. Using DGS, we identified <it>KRAS </it>as a gene that is amplified in human gastric cancer. We demonstrated that gene amplification likely forms the molecular basis of overactivation of KRAS in gastric cancer. Additional studies using a larger cohort of gastric cancer specimens are required to determine the diagnostic and therapeutic implications of <it>KRAS </it>amplification and overexpression.</p
The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016)
Background and purposeThe Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in February 2017 and published in the Journal of JSICM, [2017; Volume 24 (supplement 2)] https://doi.org/10.3918/jsicm.24S0001 and Journal of Japanese Association for Acute Medicine [2017; Volume 28, (supplement 1)] http://onlinelibrary.wiley.com/doi/10.1002/jja2.2017.28.issue-S1/issuetoc.This abridged English edition of the J-SSCG 2016 was produced with permission from the Japanese Association of Acute Medicine and the Japanese Society for Intensive Care Medicine.MethodsMembers of the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine were selected and organized into 19 committee members and 52 working group members. The guidelines were prepared in accordance with the Medical Information Network Distribution Service (Minds) creation procedures. The Academic Guidelines Promotion Team was organized to oversee and provide academic support to the respective activities allocated to each Guideline Creation Team. To improve quality assurance and workflow transparency, a mutual peer review system was established, and discussions within each team were open to the public. Public comments were collected once after the initial formulation of a clinical question (CQ) and twice during the review of the final draft. Recommendations were determined to have been adopted after obtaining support from a two-thirds (>â66.6%) majority vote of each of the 19 committee members.ResultsA total of 87 CQs were selected among 19 clinical areas, including pediatric topics and several other important areas not covered in the first edition of the Japanese guidelines (J-SSCG 2012). The approval rate obtained through committee voting, in addition to ratings of the strengths of the recommendation, and its supporting evidence were also added to each recommendation statement. We conducted meta-analyses for 29 CQs. Thirty-seven CQs contained recommendations in the form of an expert consensus due to insufficient evidence. No recommendations were provided for five CQs.ConclusionsBased on the evidence gathered, we were able to formulate Japanese-specific clinical practice guidelines that are tailored to the Japanese context in a highly transparent manner. These guidelines can easily be used not only by specialists, but also by non-specialists, general clinicians, nurses, pharmacists, clinical engineers, and other healthcare professionals
