The availability of iron limits primary productivity and the associated uptake of carbon over large areas of the ocean. Iron thus plays an important role in the carbon cycle, and changes in its supply to the surface ocean may have had a significant effect on atmospheric carbon dioxide concentrations over glacial-interglacial cycles. To date, the role of(More)
INTRODUCTION This prospective study aimed to analyze the functional outcome after a two-stage laparoscopic total proctocolectomy with ileal pouch-anal anastomosis. MATERIALS AND METHODS From May 1999 to May 2008, 68 consecutive two-stage laparoscopic total proctocolectomies with ileal pouch-anal anastomosis were performed (ulcerative colitis: n = 61;(More)
We report 15 examples of popliteal artery entrapment syndrome observed in 11 patients. The anatomical causes were as follows: in one case, the popliteal artery presented an aberrant course medially to the medial head of the gastrocnemius muscle. In 5 cases, there was a small fibrous band linking the medial head of the gastrocnemius muscle to the lateral(More)
BACKGROUND Treatment of anastomotic fistulas after bariatric surgery is difficult, and they are often associated with additional surgery, sepsis, and prolonged non-oral feeding. OBJECTIVE To assess a new, totally endoscopic strategy to manage anastomotic fistulas. DESIGN Prospective study. SETTING Tertiary-care university hospital. PATIENTS This(More)
Sudden deceleration and frontal/rear impact configurations involve rapid movements that can cause spinal injuries. This study aimed to investigate the rotation rate effect on the L2-L3 motion segment load-sharing and to identify which spinal structure is at risk of failure and at what rotation velocity the failure may initiate? Five degrees of sagittal(More)
HIV infection is associated with cytokine production by monocytes and expansion of a monocyte subset that expresses high levels of CD16. Our study was designed to investigate the effects of anti-retroviral therapies on these immune parameters. Four groups of HIV+ patients were included in the study. The first group comprised drug-naive patients (n = 20);(More)
In the field of numerical crash simulations in road safety research, there is a need to accurately define the initial conditions of a frontal impact for the car occupant. In particular, human models used to simulate such impacts barely take into account muscular contracting effects. This study aims to quantify drivers' behaviour in terms of posture and(More)
This study lies within the scope of passive road safety, and more particularly injury mechanisms of the abdominal area. The finite element modeling, which makes it possible to simulate a road accident and to observe the possible bone fractures or internal tissue injuries, allows large projections in the comprehension of injury mechanisms. However, the(More)
BACKGROUND The improvement of vulnerable users' protection has become an essential objective for our society. Injury assessments observed in clinical traumatology have led researchers and manufacturers to understand the mechanisms involved and to design safe vehicles (to reduce the severity of pedestrian injuries). METHODS In all, 137 crash tests between(More)
Hemorrhage after pancreaticoduodenectomy is a life-threatening complication, which occurs in 4% to 16% of cases, even in experienced centers. Many diagnostic and therapeutic options exist but no one has yet established management guidelines. This study aimed to determine the role of conservative management in delayed hemorrhage. From January 2005 to August(More)
