To evaluate the long-term effect of breast conservation with accelerated partial breast irradiation (APBI) for early-stage breast cancer, PubMed, EMBASE, Cochrane Library, Web of Science, Chinese Biomedical Literature Database, Chinese Scientific Journals Full-text Database, and China Journal Full-text Database were se…

We present the case of a 75-year-old man who was diagnosed with Degos disease (DD) in the context of type 2 diabetes mellitus. The cutaneous lesions of DD were located at the trunk as well as in the proximal parts of the arms. He presented with positive laboratory test for lupic anticoagulant, but other rheumatologic p…

A 73-year old man presented with the tinnitus in the left ear for 11 months. Computer tomography (CT) showed an enlarged dolichoectasia of the left vertebral artery. Magnetic resonance imaging (MRI) of the brain shows dolichoectasia of the left vertebral artery and the initial part of the basilar artery. Multi-slices c…

The near-infrared and visible wavelength spectrum of the water dimer is considered to be the major contributor to the so-called water continuum at these wavelengths. However, theoretical models of this spectrum require the simultaneous treatment of both monomer and dimer excitations. A model for treating this problem i…

The article brings a biomechanical analysis of the determination of the position of gravity centre of trainee in plane, both graphically and by calculation. The importance of determining the position of the gravity centre in different postures of a trainee should not be underestimated, as it belongs to the basic princi…

Abnormal peritoneal folds near the liver are very rare. This case report presents an observation of an abnormal fold of peritoneum that extended from the upper right part of the greater omentum and stomach to the fossa for gallbladder. This fold merged with the lesser omentum on the left and extended to the right kidne…

With academic internationalisation at full speed, English is increasingly used as a medium of instruction in higher education. The question arises of whether unbalanced bilinguals remember study materials in a non-native language (L2) as well as in a first language (L1). In previous studies, we found a disadvantage for…

Invited for the cover of this issue is the group of Pascal Van Der Voort at the University of Ghent and colleagues at Technische Universität Berlin. The image depicts the covalent triazine frameworks reported in the manuscript for the sorption of COand also in metal-free catalysis. Read the full text…

An extension of a coarse-grained, implicit-solvent peptide model wherein each amino acid residue is represented by four interaction sites is presented and discussed. The model is used to study the coil-to-helix transition of five peptide sequences, ranging from all hydrophobic to all hydrophilic, for a 10-residue pepti…

Cystic dilatation is a rare disease of extra- or intra-hepatic bile ducts. According to the literature it is an disorder accompanying other diseases rather than an independent diagnosis. In the case of smaller dimensions it is often found by coincidence because of its asymptomatic course of development. Mostly it manif…

AIM OF THE STUDY: To evaluate the results of surgical therapy of esophageal perforation in relation to the time of onset. METHODS: A retrospective study of patients records with a discharge diagnose of esophageal perforation RESULTS: During 12 years, 9 patients with esophageal perforation were treated at our surgical…

INTRODUCTION: Cases of venous thrombosis associated with celiac disease have been rarely published. We report a case of celiac disease associated with deep venous thrombosis in the left leg. MATERIAL AND METHODS: A 44-year-old man was admitted to the hospital due to diarrhea, which was present for three months. The di…

Accurate fault diagnosis of analog circuits is critical for ensuring the reliability of modern electronic systems. Two practical challenges hinder data-driven methods: data imbalance, where certain fault modes are rare, and variable operating conditions, where models trained under one fault severity fail to generalize…

BACKGROUND: The paper examines Co(II)-amino acid-imidazole systems (where amino acid = L-α-amino acid: alanine, asparagine, histidine) which, when in aqueous solutions, activate and reversibly take up dioxygen, while maintaining the structural scheme of the heme group (imidazole as axial ligand and Oupt…

We designed and implemented a generic search engine (Vaidurya), as part of our Digital clinical-Guideline Library (DeGeL) framework. Two search methods were implemented in addition to full-text search: (1) concept-based search, which relies on pre-indexing the guidelines in a clinically meaningful fashion, and (2) cont…

Authors present a case of a 78-year-old female patient with invasive ductal adenocarcinoma in the pacemaker, s pocket. A decubitus-like tumor had developed in this place, and has been missinterpretated as a benign lesion for 5 months. Diagnosis was done with a time delay. An excisional biopsy revealed annvasive ductal…

We study the phase behaviour of hard spheres confined between two parallel hard plates using extensive computer simulations. We determine the full equilibrium phase diagram for arbitrary densities and plate separations from one to five hard-sphere diameters using free energy calculations. We find a first-order fluid-so…

The availability of full text medical journal articles is rapidly increasing with the increased availability of the Internet. The potentials of the new technology present researchers, publishers, and librarians with new problems and challenges. Some resources are made available free of charge, whereas others are distri…

The myocardial performance index (MPI) is a simple quantitative, non-geometric index of ventricular function and is readily applicable for evaluation of the right and left ventricle function. The aim of the study was to assess normal MPI values in healthy children. We studied 38 healthy children from 3 to 18 years of a…

We propose an approach to predicting implicit gene-disease associations based on the inference network, whereby genes and diseases are represented as nodes and are connected via two types of intermediate nodes: gene functions and phenotypes. To estimate the probabilities involved in the model, two learning schemes are…
