Carbonate compensation depth drives abyssal biogeography in the northeast Pacific.

Abyssal seafloor communities cover more than 60% of Earth's surface. Despite their great size, abyssal plains extend across modest environmental gradients compared to other marine ecosystems. However, little is known about the patterns and processes regulating biodiversity or potentially delimiting biogeographical boundaries at regional scales in the abyss.

Artificial Intelligence for Detecting Acute Fractures in Patients Admitted to an Emergency Department: Real-Life Performance of Three Commercial Algorithms.

Rationale And Objectives: Interpreting radiographs in emergency settings is stressful and a burden for radiologists. The main objective was to assess the performance of three commercially available artificial intelligence (AI) algorithms for detecting acute peripheral fractures on radiographs in daily emergency practice.

Materials And Methods: Radiographs were collected from consecutive patients admitted for skeletal trauma at our emergency department over a period of 2 months.

Application of artificial intelligence to imaging interpretations in the musculoskeletal area: Where are we? Where are we going?

The interest of researchers, clinicians and radiologists, in artificial intelligence (AI) continues to grow. Deep learning is a subset of machine learning, in which the computer algorithm itself can determine the optimal imaging features to answer a clinical question. Convolutional neural networks are the most common architecture for performing deep learning on medical images.

Ecology of a polymetallic nodule occurrence gradient: Implications for deep-sea mining.

Abyssal polymetallic nodule fields constitute an unusual deep-sea habitat. The mix of soft sediment and the hard substratum provided by nodules increases the complexity of these environments. Hard substrata typically support a very distinct fauna to that of seabed sediments, and its presence can play a major role in the structuring of benthic assemblages.

Monitoring mosaic biotopes in a marine conservation zone by autonomous underwater vehicle.

The number of marine protected areas (MPAs) has increased dramatically in the last decade and poses a major logistic challenge for conservation practitioners in terms of spatial extent and the multiplicity of habitats and biotopes that now require assessment. Photographic assessment by autonomous underwater vehicle (AUV) enables the consistent description of multiple habitats, in our case including mosaics of rock and sediment. As a case study, we used this method to survey the Greater Haig Fras marine conservation zone (Celtic Sea, northeast Atlantic).

Megafaunal variation in the abyssal landscape of the Clarion Clipperton Zone.

The potential for imminent polymetallic nodule mining in the Clarion Clipperton Fracture Zone (CCZ) has attracted considerable scientific and public attention. This concern stems from both the extremely large seafloor areas that may be impacted by mining, and the very limited knowledge of the fauna and ecology of this region. The environmental factors regulating seafloor ecology are still very poorly understood.

An approach for the identification of exemplar sites for scaling up targeted field observations of benthic biogeochemistry in heterogeneous environments.

Continental shelf sediments are globally important for biogeochemical activity. Quantification of shelf-scale stocks and fluxes of carbon and nutrients requires the extrapolation of observations made at limited points in space and time. The procedure for selecting exemplar sites to form the basis of this up-scaling is discussed in relation to a UK-funded research programme investigating biogeochemistry in shelf seas.

Landscape-scale spatial heterogeneity in phytodetrital cover and megafauna biomass in the abyss links to modest topographic variation.

Sinking particulate organic matter (POM, phytodetritus) is the principal limiting resource for deep-sea life. However, little is known about spatial variation in POM supply to the abyssal seafloor, which is frequently assumed to be homogenous. In reality, the abyss has a highly complex landscape with millions of hills and mountains.

Oncologic outcomes after laparoscopic partial nephrectomy: mid-term results.

Introduction: To describe the oncologic outcomes of renal cell carcinoma (RCC) diagnosed in patients and submitted to laparoscopic partial nephrectomy (LPN) in a laparoscopic referral center.

Patients And Methods: We retrospectively analyzed data of 150 consecutive patients with small renal masses and treated with LPN between 2000 and 2010 at a laparoscopic referral center. Pathologic RCC was diagnosed in 137 patients and were included in the oncologic outcome analysis.

[Use of [-2] pro PSA and phi index for early detection of prostate cancer: a prospective of 452 patients].

Introduction: Early detection of prostate cancer (Pca) is a real challenge to reduce morbidity and mortality while avoiding over-diagnosis and over-treatment. The prostate specific antigen (PSA) is characterized by its imperfections justifying the evaluation of new serum or urinary specific markers allowing a better selection of patients at risk of developing aggressive Pca.

Aim: To compare the value of -2pro PSA and phi index to total and free PSA.

[Place of sclerotherapy in the treatment of chronic chyluria].

Chyluria is rare. The parasite that causes filariasis is the most common cause while the non-parasitic causes is anecdotal. Medical treatment is often insufficient to treat cases of chronic chyluria for which the standard treatment is surgical lymphatic disconnection renovascular.

Radical prostatectomy: evolution of surgical technique from the laparoscopic point of view.

Purpose: To review the literature and present a current picture of the evolution in radical prostatectomy from the laparoscopic point of view.

Materials And Methods: We conducted an extensive Medline literature search. Articles obtained regarding laparoscopic radical prostatectomy (LRP) and our experience at Institut Montsouris were used for reassessing anatomical and technical issues in radical prostatectomy.

[Tuna: clinical retrospective study addressing mid-term outcomes].

Purpose: To estimate the efficiency and morbidity of the radiofrequency (Tuna) for treatment of symptomatic benign prostatic hyperplasia (BPH) in patients with medical treatment failure.

Material And Methods: Between September 2003 and July 2007, 31 patients, mean age 59,5 years (50-76), were treated for BPH with Tuna. Patients had initially received medical treatment, which happened to fail and Tuna was offered as surgical treatment.

A transition to laparoendoscopic single-site surgery (LESS) radical prostatectomy: human cadaver experimental and initial clinical experience.

Background And Purpose: Laparoendoscopic single-site surgery (LESS) represents a novel approach to abdominal surgery. Several applications have already been described. Drawbacks include limited range of motion and need for articulated instruments.

[Evaluation of the practical skills of final year medical students: example of bladder catheterization].

Introduction: When performed incorrectly, bladder catheterization can cause iatrogenic complications, especially urinary tract infections and trauma. The objective of this study was to determine the capacity of final year medical students to perform the various bladder catheterization techniques.

Material And Methods: Between January and March 2007, a catheterization self-administered questionnaire was sent by e-mail to a representative sample of final year medical students, two months before the national classifying examination.
