Identification, analysis and prediction of valid and false information related to vaccines from Romanian tweets.

Introduction: The online misinformation might undermine the vaccination efforts. Therefore, given the fact that no study specifically analyzed online vaccine related content written in Romanian, the main objective of the study was to detect and evaluate tweets related to vaccines and written in Romanian language.

Methods: 1,400 Romanian vaccine related tweets were manually classified in true, neutral and fake information and analyzed based on wordcloud representations, a correlation analysis between the three classes and specific tweet characteristics and the validation of several predictive machine learning algorithms.

Assimilation of Both Column- and Layer-Integrated Dust Opacity Observations in the Martian Atmosphere.

A new dust data assimilation scheme has been developed for the UK version of the Laboratoire de Météorologie Dynamique Martian General Circulation Model. The Analysis Correction scheme (adapted from the UK Met Office) is applied with active dust lifting and transport to analyze measurements of temperature, and both column-integrated dust optical depth (CIDO), (rescaled to a reference level), and layer-integrated dust opacity (LIDO). The results are shown to converge to the assimilated observations, but assimilating either of the dust observation types separately does not produce the best analysis.

Contribution of the cyto-histopathological diagnosis and ultrastructural parameters to the evaluation of maxillary cysts - a 10-year multidisciplinary approach.

Diagnostic and treatment plans in cystic jawbone tumors are often difficult to address. The etiopathogenic links involved in cell-matrix differentiation disorders are complex. Quantification of the inflammatory process in the evolution of cystic odontogenic lesions highlights a particular reactivity of the host, especially age-dependent and the endodontic-periodontal space interrelation, drawing attention to the difficulties of etiopathogenic, evolution, prognostic and treatment of these lesions.

Obtaining and Characterization of a Polydisperse System Used as a Transmembrane Carrier for Isosorbide Derivatives.

Due to their effect of vasodilatation, isosorbide nitrates represent one of the most important and most used solutions for angina pectoris. Unfortunately, these compounds have multiple dose-related adverse drug reactions such as headache, weakness, mild dizziness, and occasionally heart rate changes, nausea, vomiting, and sweating. The main aims of this research were to obtain and to evaluate new polyurethane (PU) structures that can be used as a proper transmembrane carrier with an improved release kinetic.

The development of a scoring and ranking strategy for a patient-tailored adverse drug reaction prediction in polypharmacy.

Only few applications are currently dealing with personalized adverse drug reactions (ADRs) prediction in case of polypharmacy. The study aimed to develop a patient-tailored ADR web application, considering characteristics from 734 drugs and relevant patient related factors. The application was designed in Python using a scoring and ranking system based on frequency and severity, computed for each ADR and expressed through an online platform.

Sperm quality in frozen beef and dairy bull semen.

Background: There is speculation that beef bull semen quality is inferior to that of dairy bulls although few scientific studies are available in the literature. The aim of this study was to evaluate sperm quality in beef bull semen and to determine which parameters could be indicative of fertility after insemination. Sperm quality, assessed by computer assisted sperm motility analysis and flow cytometric evaluation of membrane integrity, levels of reactive oxygen species, mitochondrial membrane potential, acrosome status and DNA fragmentation index, was evaluated in beef and dairy bull semen.

Giant maxillary cyst with intrasinusal evolution.

Giant maxillary cysts deserve one's attention, mainly because of all the complication they can originate, such as facial aesthetic changes, jaw fractures, infections and occasional but the most severe one the neoplasia of its epithelium. Here we present the case of a 51-year-old man who was sent to the Clinic of Oral and Maxillofacial Surgery of Timisoara, Romania, because of a facial asymmetry due to the hyper-dimension of the right superior genian and labial region, consecutive to the volume growth of the subjacent alveolar process. The clinical and paraclinical investigations, especially the fine-needle aspiration and the 3D imagistic investigation, most likely lead to the diagnosis of maxillary cyst with intrasinusal evolution, the lesion being caused by the untreated teeth of the superior right hemiarcade.

The role of color histograms in predicting the prognosis of patients with digestive tract adenocarcinoma.

Objectives: To establish the correlation between the degree of vascularisation detected using power Doppler ultrasonography in digestive tract adenocarcinoma and the prognosis of these patients.

Material And Method: Ultrasonography was performed in 45 patients diagnosed with digestive tract adenocarcinoma (16 stomach-35.6%, 6 cecum and ascending colon-13.

The posterior intrahepatic approach to the left portal pedicle using the ligamentum venosum: anatomical basis.

Purpose: Prevention of blood loss in liver resections is essential for reducing postoperative morbidity. The main method to control bleeding during surgery of the left hemiliver is occlusion of the left portal pedicle. This may be accomplished by hilar, fissural or posterior intrahepatic techniques.

Magnetic resonance-guided focused ultrasound surgery (MRgFUS). Four ablation treatments of a single canine hepatocellular adenoma.

Background: Canine hepatocellular adenomas are benign, well-differentiated, primary hepatic tumors. Surgical resection is technically demanding and is considered a major procedure with relatively high morbidity rates. Magnetic resonance-guided focused ultrasound surgery (MRgFUS) uses focused ultrasonic energy to non-invasively create a heat-coagulated lesion deep within the body.

Magnetic resonance-guided focused ultrasound surgery (MRgFUS): ablation of liver tissue in a porcine model.

Background: Liver surgery is technically demanding and is considered a major procedure with relatively high morbidity rates. Magnetic resonance-guided focused ultrasound surgery (MRgFUS) uses focused ultrasonic energy to create a heat coagulation lesion, which can be achieved in a totally controlled, very accurate manner (<1 mm). The aim of this study was to evaluate the safety and accuracy of non-invasive focal ablation of liver tissue achieved by consecutive MRgFUS sonications.

Use of transportal balloon catheter occlusion of the portal triad in prevention of bleeding during liver resection.

Background: Operative blood loss is among the most important factors determining the prognosis of patients undergoing hepatic resection. The best method for preventing bleeding is preliminary selective vascular occlusion of lobar, sectoral, or segmental portal triads, although not always technically feasible.

Method: Transportal occlusion of the portal triad with a balloon catheter was used in 35 hepatectomies for various tumors.

Rescue surgery for unresectable colorectal liver metastases downstaged by chemotherapy: a model to predict long-term survival.

Objective: To evaluate the long-term survival of patients resected for primarily unresectable colorectal liver metastases (CRLM) downstaged by systemic chemotherapy and to use prognostic factors of outcome for a model predictive of survival on a preoperative setting.

Summary Background Data: Surgery of primarily unresectable CRLM after downstaging chemotherapy is still questioned, and prognostic factors of outcome are lacking.

Methods: From a consecutive series of 1439 patients with CRLM managed in a single institution during an 11-year period (1988-1999), 1104 (77%) initially unresectable (NR) patients were treated by chemotherapy and 335 (23%) resectable were treated by primary liver resection.
