To acquire extremely thermostable proteins of given functions is challenging for conventional protein engineering. Here we applied ABACUS, a statistical energy function we developed for de novo amino acid sequence design, to globally redesign a Ras-binding domain (RBD), and obtained an extremely thermostable RBD that unfolds reversibly at above 110°C, the redesigned RBD experimentally confirmed to have expected structure and Ras-binding interface. Directed evolution of the redesigned RBD improved its Ras-binding affinity to the native protein level without excessive loss of thermostability. The designed amino acid substitutions were mostly at the protein surface. For many substitutions, strong epistasis or significantly differentiated effects on thermostability in the native sequence context relative to the redesigned sequence context were observed, suggesting the globally redesigned sequence to be unreachable through combining beneficial mutations of the native sequence. find more Further analyses revealed that by replacing 38 of a total of 48 non-interfacial surface residues at once, ABACUS redesign was able to globally "invert" the protein's charge distribution pattern in an optimized way. Our study demonstrates that computational protein design provides powerful new tools to solve challenging protein engineering problems.

To determine whether patients with epilepsy (PWE) are particularly over-represented in a very large cohort of patients with COVID-19. We also investigated whether COVID-19 is associated with a different clinical picture or a more severe course of illness in PWE (compared with others).

All consecutive patients who referred to and admitted at healthcare facilities anywhere in Fars province (located in the south of Iran with a population of 4,851,000 people) from February 19, 2020 until November 20, 2020 were included.

A total of 37,968 patients were studied. Eighty-two patients (0.2%) had pre-existing epilepsy. link= find more Seizures were significantly more frequent among PWE as a presenting manifestation of COVID-19 compared with that in people without epilepsy (Odds Ratio=27; p=0.0001). Furthermore, PWE less often reported cough (significantly) and more often had gastrointestinal symptoms (vomiting and anorexia; as trends) compared with those in people without epilepsy. Patients with epilepsy were not differently likhould be investigated and clarified in the future studies.The COVID-19 pandemic has greatly heightened interest in ultraviolet germicidal irradiation (UVGI) as an important intervention strategy to disinfect air in medical treatment facilities and public indoor spaces. However, a major drawback of UVGI is the challenge posed by assuring safe installation of potentially hazardous short-wavelength (UV-C) ultraviolet lamps. Questions have arisen regarding what appear to be unusually conservative exposure limit values in the UV-C spectral band between 180 and 280 nm. We review the bases for the current limits and proposes some adjustments that would provide separate limits for the eye and the skin at wavelengths less than 300 nm and to increase both skin and eye limits in the UV-C below 250 nm.

Inflammation plays an important role in the ageing process in which monocytes/macrophages are important players. Intercellular adhesion molecule-1 (ICAM-1), tumour necrosis factor-α (TNF-α) and Toll-like receptor 4 (TLR4) are well-known inflammatory markers. This study aimed to investigate the relationship between age and the expression and correlation of ICAM-1, TNF-α and TLR4 mRNA in peripheral blood mononuclear cells (PBMCs).

A total of 239 participants were recruited in a medical centre in Taiwan. The mRNA isolated from the PBMCs was used to determine the levels of ICAM-1, TNF-α and TLR4 mRNAs with real-time polymerase chain reaction (PCR). The propensity-matched analysis was also applied for subgroup analysis.

When compared 189 older adults (≧65years) to 50 younger adults (<65years), the ICAM-1, TNF-α and TLR4 mRNA levels in PBMCs were significantly higher in older adults (2.00±0.72 vs 0.87±0.34 for ICAM-1, 2.32±0.69 vs 1.15±0.44 for TNF-α and 1.56±0.47 vs 1.05±0.51 for TLR4, and all P<.0001). Also, both age and TLR4 were independent factors affecting mononuclear cell ICAM-1 in the multiple linear regression analysis (P<.0001).

The mRNA levels of ICAM-1 and TLR4 in PBMCs are higher in older adults than those in younger adults. find more TLR4 is an independent factor affecting ICAM-1 expression in PBMCs, especially in older adults. This may suggest that ICAM-1 and TLR4 in PBMCs are potential biomarkers and their relationship may shed some light on the ageing process.

Therefore, the aim of this survey was to assess national practices for paediatric procedural sedation outside operation rooms and intensive care units in terms of indications, sedative medication, treatment facilities, patient safety and training of the personnel. An online survey including single- and multiple-choice questions and open-ended questions was sent to Finnish paediatricians, paediatric surgeons and paediatric anaesthesiologists via the electronic mailing lists of national societies in December 2019. A total of 71 responses were received. Lumbar puncture (41%), intra-articular injections (38%) and MRI (17%) were the most common procedures that required routine sedation. Benzodiazepines were the most frequently used sedatives during both painful procedures (80%) and imaging (61%). Pulse oximetry monitoring was reported by 75% of the respondents, but other physiological parameters were rarely monitored (ECG 28%; blood pressure 39%; respiratory rate 34%). link2 The level of sedation was not objectively assessed. Adrenaline (72%) and equipment for managing adverse respiratory outcomes (supplemental oxygen 98%; ventilation equipment 92%) were available in most facilities in which sedation was performed. Only one-third of the respondents had undergone training for paediatric procedural sedation, and only 39% of the hospital units compiled statistical data on sedation-related adverse events. The paediatric procedural sedation practices vary across hospitals. National guidelines for patient monitoring and training of personnel could improve treatment quality and patient safety.

Interleukin 11 (IL11) is highly upregulated in skin and lung fibroblasts from patients with systemic sclerosis (SSc). Here we tested whether IL11 is mechanistically linked with activation of human dermal fibroblasts (HDFs) from patients with SSc or controls.

We measured serum IL11 levels in volunteers and patients with early diffuse SSc and manipulated IL11 signalling in HDFs using gain- and loss-of-function approaches that we combined with molecular and cellular phenotyping.

In patients with SSc, serum IL11 levels are elevated as compared with healthy controls. All transforming growth factor beta (TGFβ)isoforms induced IL11 secretion from HDFs, which highly express IL11 receptor α-subunit and the glycoprotein 130 (gp130) co-receptor, suggestive of an autocrine loop of IL11 activity in HDFs. link2 IL11 stimulated ERK activation in HDFs and resulted in HDF-to-myofibroblast transformation and extracellular matrix secretion. link3 The pro-fibrotic action of IL11 in HDFs appeared unrelated toSTAT3 activity, independent of TGFβ upregulation and was not associated with phosphorylation of SMAD2/3. Inhibition of IL11 signalling using either a neutralizing antibody against IL11 or siRNA against IL11RA reduced TGFβ-induced HDF proliferation, matrix production and cell migration, which was phenocopied by pharmacological inhibition of ERK.

These data reveal that autocrine IL11-dependent ERK activity alone or downstream of TGFβ stimulation promotes fibrosis phenotypes in dermal fibroblasts and suggest IL11 as a potential therapeutic target in SSc.

Currently, an aid from the American College of Sports Medicine exists to help oncology care providers advise, assess, and refer patients to physical activity (PA). However, some limitations include the lack of specific resources and programs for referral, detailed PA, and physical function assessments and not being designed following an international gold standard (Appraisal of Guidelines for Research and Evaluation [AGREE] II). This study aimed to develop a recommendation guide to facilitate PA counseling by assessing the risk for PA-related adverse events and offering a referral to an appropriate recommendation. Recommendation guide development followed AGREE II, and an AGREE methodologist was consulted. Specifically, a stakeholder group of oncology care providers and cancer survivors were engaged to develop the assessment criteria for comorbidities, PA levels, and physical function. Assessment criteria were developed from published PA interventions, consultations with content experts, and targeted web-based searches for cancer-specific PA programs. Feedback on the recommendation guide was solicited from stakeholders and external reviewers with relevant knowledge and clinical experience. Independent AGREE methodologists appraised the development process. The recommendation guide is a five-page document, including a preamble, assessment criteria for absolute contraindications to PA, comorbidities, and PA/functional capacity with a list of appropriate resources. Independent AGREE methodologists rated the development process as strong and recommended the guide for use. The recommendation guide has the potential to facilitate PA counseling between oncology care providers and cancer survivors, thus, potentially impacting PA behavior.Omics technologies offer great promises for improving our understanding of diseases. The integration and interpretation of such data pose major challenges, calling for adequate knowledge models. Disease maps provide curated knowledge about disorders' pathophysiology at the molecular level adapted to omics measurements. However, the expressiveness of disease maps could be increased to help in avoiding ambiguities and misinterpretations and to reinforce their interoperability with other knowledge resources. link3 Ontology is an adequate framework to overcome this limitation, through their axiomatic definitions and logical reasoning properties. We introduce the Disease Map Ontology (DMO), an ontological upper model based on systems biology terms. We then propose to apply DMO to Alzheimer's disease (AD). Specifically, we use it to drive the conversion of AlzPathway, a disease map devoted to AD, into a formal ontology Alzheimer DMO. We demonstrate that it allows one to deal with issues related to redundancy, naming, consistency, process classification and pathway relationships.
