Comments on 'formation and characterization of nanotubes of La(OH) 3 obtained using porous alumina membranes'

2010

New experimental evidence concerning the formation of La(OH)3 nanowires on anodic alumina membranes by cathodic polarization in 0.05 M lanthanum nitrate solution is provided to further support the conclusions previously reached in our work (Bocchetta et al 2007 Electrochem. Commun. 9 683-8) and recently criticized by González-Rovira et al (Nanotechnology 2008 19 495305). Some unconvincing aspects of the paper of González-Rovira et al, according to which the same electrochemical process should lead to the formation of hydroxycarbonate nanotubes, are also discussed.

EP260 Is there still a role for laparoscopic radical hysterectomy? Personalizing surgical approach in early stage cervical cancer

2019

Introduction/Background To compare survival outcomes of laparoscopic and open surgery for radical hysterectomy (RH) among patients with early-stage cervical cancer (CC) and to identify which subgroups may benefit from one approach rather than the other. Methodology 237 and 303 consecutive patients, with clinical FIGO stage from IA1 with lymph vascular space involvement to IB1/IIA1 CC underwent open and laparoscopic RH respectively in 3 Italian Institutions. Differences in terms of progression-free survival (PFS) between the two surgical approaches were tested in the entire population and in different patient‘s subgroups. Results Median follow up was 34 months. Open and laparoscopy procedure…

Data from: Plant – herbivorous beetle networks: molecular characterization of trophic ecology within a threatened steppic environment

2015

DNA barcoding facilitates many evolutionary and ecological studies, including the examination of the dietary diversity of herbivores. In this study, we present a survey of ecological associations between herbivorous beetles and host plants from seriously threatened European steppic grasslands. We determined host plants for the majority (65%) of steppic leaf beetles (55 species) and weevils (59) known from central Europe using two barcodes (trnL and rbcL) and two sequencing strategies (Sanger for mono/oligophagous species and Illumina for polyphagous taxa). To better understand the ecological associations between steppic beetles and their host plants, we tested the hypothesis that leaf beetl…

Head and neck squamous cell carcinoma in people living with HIV in France.

2018

Abstract Objectives Head and neck squamous cell carcinoma (HNSCC), mainly due to smoking, is one of the leading causes of cancer deaths. However, an increasing number of tumors – especially oropharyngeal cancer – are reported in non-smokers in association with the human papillomavirus (HPV). As HIV-infected individuals are particularly at risk of HPV-related disease, we aimed to describe the burden of HNSCC in this population. Methods Retrospective chart review of patients from HIV clinics diagnosed with HNSCC between 2004 and 2014. Case patients were defined using the International Classification of Disease for Oncology (3rd edition). Age at HIV diagnosis and time from HIV diagnosis to HNS…

[Use of imaging criteria to identify cervical metastases using CT scans in head and neck tumours].

2008

Abstract Objective To assess the diagnostic certainty of CT images to identify regional spread of head and neck tumours. Patients and method A CT study was performed on 86 patients with neoplasms in the larynx and/or pharynx. After this, surgical dissection was performed for 142 neck sides. In the imaging study the following parameters were considered for all patients before suspecting malignant nodes: size of adenopathy bigger than 10–11 mm, irregular borders, central necrosis, spherical shape, capsular enhancement, and presence of groups with 3 or more lymphadenopathies. Results 48.5% of dissections were N+. Sensitivity and specificity for physical examination were 59% and 82%, respective…

Measure of a limestone weathering degree using Laser Scanner.

2013

The weathering degree of the building materials and natural stones is generally quantified as the decrement of some mechanical features that can be measured experimentally by means of compressive tests or point load tests in the laboratory or Schmidt hammer tests carried out in situ. Such destructive or damaging tests are unacceptable in case of cultural heritage since even small amounts of damage must be avoided. This work shows a correlation between Schmidt hammer rebound values and the reflectivity that is detected by means of terrestrial scanner laser; therefore it allows assessing the weathering degree of buildings or stones in situ. The results demonstrate that such an investigation c…

A genetic link between synsedimentary tectonics-expelled fluids, microbial sulfate reduction and cone-in-cone structures

2018

14 pages; International audience; The late Jurassic (Tithonian) marlstones of the Boulonnais area (English Channel, France) contains diagenetic carbonate beds and nodules. Some nodules exhibit cone-in-cone structures on their lower face. We studied such nodules using various techniques of imaging and chemical (major and trace-elements) and isotopic analyses (Ccarb, Corg, O and S stable isotopes). We interpret the cone-in-cone to be the end product of carbonate-nodule formation during early diagenesis. The diagenetic carbonate precipitation was induced by microbial activity (bacteria and(?) archeae) fueled by upward-migrating fluids. Fluid expulsion was itself triggered by synsedimentary fau…

Latvijas Universitātes Filoloģijas un filozofijas fakultātes Vēstures nodaļa studentu lietās (1919-1940)

2015

Darbs veltīts Latvijas Universitātes Filoloģijas un filozofijas fakultātes Vēstures nodaļas izpētei. Tajā tiek aprakstīts studentu sastāvs un studiju organizācija nodaļā, sniedzot ieskatu Vēstures nodaļas darbībā no 1919. gada, kad tā tika dibināta, – līdz Latvijas Universitātes likvidācijai 1940. gadā. Nozīmīgākie darbā izmantotie materiāli ir Vēstures nodaļas absolventu studentu personīgās lietas, kuras iepriekš nav pētītas. No lietām iegūto informāciju papildinot ar skaidrojumiem historiogrāfijā un citiem materiāliem, tiek parādīts Vēstures nodaļas nozīmīgums Latvijas vēsturē.
