Background: Lu-oxodotreotide peptide receptor therapy (LuPRRT) is an efficient treatment for midgut neuroendocrine tumors (NETs) of variable radiological response. Several clinical, biological, and imaging parameters may be used to establish a relative disease prognosis but none is able to predict early efficacy or toxicities. We investigated expression levels for mRNA and miRNA involved in radiosensitivity and tumor progression searching for correlations related to patient outcome during LuPRRT therapy.

The bone marrow dose is generally derived from a SPECT/CT image-based method with four timepoints or from a blood-based method with up to 9 timepoints, but there is still no reference method. This retrospective single-center study on the same cohort of patients compared the calculated bone marrow dose administered with both methods using mono, bi- or tri-exponential models.

The aim of this study was to investigate the impact of radiation on different immune structures and immune cells in patients treated with CCRT followed by durvalumab.
Material And Methods: Clinicopathologic data, pre- and post-treatment blood counts, and dosimetric data were collected in patients treated with CCRT and durvalumab consolidation for LA-NSCLC.
Salivary gland cancers are rare tumors comprising a large group of heterogeneous tumors with variable prognosis. Their therapeutic management at a metastatic stage is challenging due to the lack of therapeutic lines and the toxicity of treatments. [Lu]Lu-PSMA-617 (prostate-specific membrane antigen) is a vectored radioligand therapy (RLT) initially developed to treat castration-resistant metastatic prostate cancer with encouraging results in terms of efficacy and toxicity.
View Article and Find Full Text PDFAmong all RNA viruses, coronavirus RNA transcription is the most complex and involves a process termed "discontinuous transcription" that results in the production of a set of 3'-nested, co-terminal genomic and subgenomic RNAs during infection. While the expression of the classic canonical set of subgenomic RNAs depends on the recognition of a 6- to 7-nt transcription regulatory core sequence (TRS), here, we use deep sequence and metagenomics analysis strategies and show that the coronavirus transcriptome is even more vast and more complex than previously appreciated and involves the production of leader-containing transcripts that have canonical and noncanonical leader-body junctions. Moreover, by ribosome protection and proteomics analyses, we show that both positive- and negative-sense transcripts are translationally active.

Many studies have focused on laboratory isolates that have been extensively adapted for growth on fibroblasts. Here, we report whole-genome sequences for 10 human cytomegalovirus (HCMV) strains that readily grow on ARPE-19 human retinal pigment epithelial cells.

An isolate from a drill monkey, OCOM6-2, and an isolate from a chacma baboon, OCOM4-52, were subjected to pyrosequencing and assembled. Comparative alignment of published primate cytomegaloviruses (CMVs) showed variable sequence conservation between species.

While over the last thirty years numerous studies have attempted to outline a detailed chronostratigraphy for this important sequence, the failure to employ a common chronological framework has complicated its interpretation. Here, we aim to resolve these inconsistencies by providing a new chronology for the site based on luminescence dating.

Close to the time of replacement, Neandertals show behaviors similar to those of the modern humans arriving into Europe, including the use of specialized bone tools, body ornaments, and small blades. It is highly debated whether these modern behaviors developed before or as a result of contact with modern humans.

The chosen method is based on the Deming wheel, that is to say: 1) Forward planning, done by the quality department of the work organization. 2) Drafting of a task descriptive file of the laboratory technician (working hours, equipments, done analysis, three levels of qualification, recurrent tasks, periodic hours, occasional hours, reference document).
View Article and Find Full Text PDFThe Châtelperronian is a Neandertal-associated archeological culture featuring ornaments and decorated bone tools. It is often suggested that such symbolic items do not imply that Neandertals had modern cognition and stand instead for influences received from coeval, nearby early modern humans represented by the Aurignacian culture, whose precocity would be proven by stratigraphy and radiocarbon dates. The Grotte des Fées at Châtelperron (France) is the remaining case of such a potential Châtelperronian-Aurignacian contemporaneity, but reanalysis shows that its stratification is poor and unclear, the bone assemblage is carnivore-accumulated, the putative interstratified Aurignacian lens in level B4 is made up for the most part of Châtelperronian material, the upper part of the sequence is entirely disturbed, and the few Aurignacian items in levels B4-5 represent isolated intrusions into otherwise in situ Châtelperronian deposits.

Tuberculosis and myelofibrosis are reported in conjunction often enough to raise the possibility that a relationship exists between the 2 entities. However, whether tuberculosis stimulates a secondary fibrotic reaction or develops in patients who have preexisting myeloproliferative disorders is not clear. We describe the case of a 28-year-old man in whom myelofibrosis disappeared completely after administration of antituberculous treatment, which suggests that a causal relationship exists between the 2 disease entities.

Cerebrovascular accidents (CVAs) are the third commonest cause of death in France. Approximately 15% of them are due to stenosis of the extracranial internal carotid. The fact that a third of CVAs are followed by death and another third by major handicaps leads to the need for careful prevention.

Abdominal trauma is a rare and poorly documented cause of portal vein thrombosis. We report here the case of a patient in whom portal vein thrombosis was diagnosed one month after an abdominal blunt trauma. Post-traumatic origin of thrombosis was confirmed by the negativity of an exhaustive aetiological investigation.
