Erich Hückel’s Education and Scientific Awakening: The Path to Quantum Chemistry

2009

A lucky star seems to have hung over the year 1896 for quantum chemistry. Three of its founders in the 20th century were born in that year: Erich Huckel, Friedrich Hund and Robert S. Mullikan. Armand Arthur Erich Joseph Huckel was born on August 9, 1896 in Charlottenburg, on the outskirts of Berlin, as the second of three sons to Marie Huckel (1879–1947) nee Maier and the lecturer and medical doctor Armand Huckel (1860–1927). He spent his first 3 years in Charlottenburg with his brother Walter, who was a year older than him, in a spatious apartment on the first story of a building on Schluterstrasse before the arrival of their younger brother Rudi

Impact of hydrothermal ageing on the thermal stability, morphology and viscoelastic performance of PLA/sisal biocomposites

2016

The influence of the combined exposure to water and temperature on the behaviour of polylactide/sisal biocomposites coupled with maleic acid anhydride was assessed through accelerated hydrothermal ageing. The biocomposites were immersed in water at temperatures from 65 to 85 °C, between the glass transition and cold crystallisation of the PLA matrix. The results showed that the most influent factor for water absorption was the percentage of fibres, followed by the presence of coupling agent, whereas the effect of the temperature was not significant. Deep assessment was devoted to biocomposites subjected to hydrothermal ageing at 85 °C, since it represents the extreme degrading condition. Th…

Emergency sclerotherapy or band ligation combined with vasoactive drugs for bleeding esophageal varices in cirrhosis

2019

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To assess the efficacy as well as adverse events of emergency sclerotherapy (or band ligation) combined with pharmacological treatments versus sclerotherapy (or band ligation) alone or vasoactive drugs alone for acute variceal bleeding in cirrhotic patients based on the results of randomised clinical trials (RCTs).

Case Report: The JAK-Inhibitor Ruxolitinib Use in Aicardi-Goutieres Syndrome Due to ADAR1 Mutation

2021

Type I Interferonopathies comprise inherited inflammatory diseases associated with perturbation of the type I IFN response. Use of Janus kinase (JAK) inhibitors has been recently reported as possible tools for treating some of those rare diseases. We describe herein the clinical picture and treatment response to the JAK-inhibitor ruxolitinib in a 5-year-old girl affected by Aicardi-Goutières Syndrome type 6 (AGS6) due to ADAR1 mutation. The girl's interferon score (IS) was compared with that of her older brother, suffering from the same disorder, who was not treated. We observed a limited, but distinct neurological improvement (Gross Motor Function and Griffiths Mental Development Scales). …

A progressive stage IIIB melanoma treated with oncolytic ECHO-7 virus: A case report

2020

Melanoma is an aggressive skin cancer form with a grave prognosis. Current results suggest that oncolytic virus treatment of melanoma has a high therapeutic potential. ECHO-7 (Rigvir) is the first oncolytic virus registered in Latvia. A female patient was diagnosed with stage IIIB melanoma in December 2012, over 9.4 years ago. After the first excision and re-excision, the patient had several recurrences and disease progressions. After the patient had received surgical treatment in 2014, ECHO-7 virus oncolytic virotherapy was started. Since then, the patient has experienced only one more disease progression episode in May 2015 and has been stable for over 60 months. The patient has not rece…

The cultivable human oral gluten-degrading microbiome and its potential implications in coeliac disease and gluten sensitivity

2013

AbstractCoeliac disease is characterized by intestinal inflammation caused by gluten, proteins which are widely contained in the Western diet. Mammalian digestive enzymes are only partly capable of cleaving gluten, and fragments remain that induce toxic responses in patients with coeliac disease. We found that the oral microbiome is a novel and rich source of gluten-degrading organisms. Here we report on the isolation and characterization of the cultivable resident oral microbes that are capable of cleaving gluten, with special emphasis on the immunogenic domains. Bacteria were obtained by a selective culturing approach and enzyme activities were characterized by: (i) hydrolysis of paranitr…

Comparison between Disk Diffusion and Microdilution Methods for Determining Susceptibility of Clinical Fungal Isolates to Caspofungin

2007

ABSTRACT We compared the caspofungin (CAS) susceptibility testing results generated by the disk diffusion (DD) assay with the results of the Clinical and Laboratory Standards Institute (CLSI) broth microdilution (BD) reference method for 106 yeast isolates. The isolates represented 11 different fungal species, including Candida albicans ( n = 50), C. parapsilosis ( n = 10), C. glabrata ( n = 10), C. tropicalis ( n = 10), C. guillermondii ( n = 6), C. rugosa ( n = 5), C. krusei ( n = 5), C. kefyr ( n = 2), C. pelliculosa ( n = 2), Saccharomyces cerevisiae ( n = 3), and Geotrichum candidum ( n = 3). The DD assay was performed in supplemented Mueller-Hinton agar with CAS, which was tested at c…

Evaluation of the Disk Diffusion Method Compared to the Microdilution Method in Susceptibility Testing of Anidulafungin against Filamentous Fungi

2008

ABSTRACT Susceptibility testing of anidulafungin (AFG) against 32 mold isolates showed an excellent correlation between disk diffusion (DD) and broth microdilution methods. Based on our data, a 2-μg disk of AFG and a 24-h reading time might represent the best parameters for AFG DD testing against filamentous fungi.

More than Pneumonia: Distinctive Features of SARS-Cov-2 Infection. From Autopsy Findings to Clinical Implications: A Systematic Review

2020

Despite safety recommendations for the management of corpses with COVID-19 infection and the high number of deaths worldwide, the post-mortem investigation rate is extremely low as well as the scientific contributions describing the pathological features. The first results of post-mortem investigations provided interesting findings and contributed to promoting unexplored therapeutic approaches and new frontiers of research. A systematic review is provided with the aim of summarizing all autopsy studies up to February 2020 in which a complete post-mortem investigation in patients with COVID-19 disease was performed, focusing on histopathological features. We included case reports, case serie…
