Site Occupancy Determination in ThZn- and TbCu-types SmFeCo Compounds using Synchrotron Resonant Diffraction.

SmFe compounds are high-performance permanent magnets. Cobalt substitution allows us to further improve their magnetic properties. Depending on the thermal treatment, cobalt-substituted compounds can be synthesized either in the TbCu (disordered) or in the ThZn (ordered) structure type.

Modeling and determination of directionality of the kerf in epifluorescence sharp bone trauma analysis.

Characteristics of sharp bone trauma can be extremely useful to determine the origin of cut marks and to provide information regarding the context of death. Using human ribs and clavicle bones, this study analyzes the characteristics of bone kerfs made by different bladed implements, thanks to epifluorescence macroscopy. This technique, which is a nondestructive tool that uses autofluorescence of bones, documents bone damage precisely with high resolution.

Sexual function of young women with myelomeningocele.

Objectives: To assess the sexual function of young women with spina bifida and myelomeningocele and to determine the factors influencing their sexual function.

Methods: A postal cross-sectional study using a self-administered questionnaire was performed in 44 women, mean age 27.66 ± 5.

Unusual duplicate bladder exstrophy in a female newborn: a case report.

The authors report a rare variant of exstrophy-epispadias complex, a duplicate bladder with normal bladder communicating with an exstrophic bladder by a fistula, in a girl with no genital malformation except for a duplicated clitoris. This variant could be a hybrid form of duplicate bladder exstrophy and superior vesical fistula. It seems easier to repair and has a better prognosis than classic bladder exstrophy.

Anatomy of the bands of the hamstring tendon: how can we improve harvest quality?

Background: The hamstring tendons, gracilis and semitendinosus are widely used in ligament and reconstructive surgery. Their accessory bands or insertions are technical pitfalls during harvesting.

Methods: Thirty fresh cadaver knees have been studied, in order to 1) determine the anatomy of the bands of the gracilis and semitendinosus tendons, and, 2) to identify risk factors for failure during harvesting.

Anatomical basis of the risk of injury to the right laryngeal recurrent nerve during thoracic surgery.

Purpose: Despite the intrathoracic part being short, the right laryngeal recurrent nerve is often injured during thoracic surgery. The aim of this cadaver study was to understand the mechanisms of right laryngeal recurrent nerve injuries during thoracic surgery and to describe anatomical landmarks for its preservation.

Methods: Dissections were performed on 10 fresh human cadavers.

Deciphering the elusive nature of sharp bone trauma using epifluorescence macroscopy: a comparison study multiplexing classical imaging approaches.

Characterization of sharp-force trauma on human bones can be extremely useful in providing information regarding the nature and context of death. Nevertheless, in the identification of weapons used to cause sharp-force trauma and analysis of bone wounds, challenging tasks still remain. Current analysis attempting to dissect bone wound characteristics varied quite a lot and mixed different criteria, thus leading sometimes to conflicting results.

Anatomic variations of the renal vessels: focus on the precaval right renal artery.

The aim of this study was to determine the prevalence of precaval right renal artery and to investigate the distribution of renal arteries and veins. We discuss a theory of development of renal vascular variants. We retrospectively reviewed 120 arterial phase contrast material-enhanced spiral computerized tomography scans of the abdomen (1- to 2-mm section thickness) performed during a two-month period.

The anconeus, an active lateral ligament of the elbow: new anatomical arguments.

Purpose: As there are a few detailed anatomical studies of the active function of anconeus muscle in stabilizing the elbow, we aimed to look for anatomical features confirming its role as an active stabilizer of the humero-ulnar joint.

Methods: Thirty fresh unembalmed elbows from 15 cadavers were dissected. We examined the anatomy, insertions, relationships and orientation of the muscle fibres of the anconeus.

Ovarian germ cell tumors in children. Management, survival and ovarian prognosis. A report of 75 cases.

Background/purpose: The aims of this study were to evaluate survival and ovarian prognosis in patients treated for ovarian germ cell tumor (OGCT) and to propose a decision-making protocol.

Methods: Charts of girls operated on for OGCT from 1976 up to 2009 were reviewed retrospectively. Tumor characteristics were assessed by tumor markers, imaging, and pathology.

Ovarian torsion. Management and ovarian prognosis: a report of 45 cases.

Background/purpose: Ovarian torsion in childhood and adolescence is a rare entity. Traditionally, treatment is oophorectomy. The aim of this study was to evaluate ovarian outcome and to propose a decision-making protocol for suspected ovarian torsion.

EXAFS structural study of platinum-based anticancer drugs degradation in presence of sulfur nucleophilic species.

Three platinum complexes, cisplatin, carboplatin and oxaliplatin are currently used worldwide. Investigation of their main structural modifications in presence of sulfur nucleophiles is of particular interest because of the implication of thiol and thioether groups in biochemical mechanism of action, resistance mechanism and in vivo or in vitro detoxification. We present the main structural results we have obtained concerning the reaction of these drugs with diverse sulfur nucleophiles (cysteine, glutathione, methionine, thiosulfate and thiocyanate), monitored in solution or as precipitates by EXAFS spectroscopy.

Fetal ovarian cysts management and ovarian prognosis: a report of 82 cases.

Background/purpose: Fetal ovarian cysts are frequently complicated by intracystic hemorrhage without associated clinical signs, which is often secondary to ovarian torsion leading to loss of the ovary. The aim of this study was to evaluate ovarian outcome and the place of prenatal management and surgery in the first few days of life in order to save the ovary.

Methods: Between January 1987 and June 2006, 82 fetal ovarian cysts in 79 patients were managed and clinically and ultrasonographically followed up for several months (median, 11 months; range, 6 months to 10 years) in all of the cases where the ovary was not removed.

Evaluation of sexual function in young men with spina bifida and myelomeningocele using the International Index of Erectile Function.

Objectives: To assess sexual function in young men with spina bifida and myelomeningocele.

Methods: Between November 2003 and February 2004, a cross-sectional study was performed in 55 men older than 18 years of age who had been regularly followed up for myelomeningocele since childhood, between 1961 and 1985, in the Pediatric Internal Surgery Department. The International Index of Erectile Function (IIEF) questionnaire was mailed to each man.

The outcome of prenatally diagnosed renal tumors.

Purpose: We assessed the incidence of perinatal morbidity and evaluated the outcome in children with prenatally diagnosed renal tumors in a retrospective multicenter study.

Materials And Methods: A review of the records of patients from 20 institutions identified 28 children with prenatally diagnosed renal tumors. Prenatal findings, clinical charts, and radiological, surgical and pathological reports were reviewed in this study.

A spin transition molecular material with a wide bistability domain.

[Fe(hyptrz)3](4-chloro-3-nitrophenylsulfonate)22 H2O (1; hyptrz=4-(3-hydroxypropyl)-1,2,4-triazole) has been synthesized and its physical properties have been investigated by several physical techniques including magnetic susceptibility measurements, calorimetry, and Mössbauer, optical, and EXAFS spectroscopy. Compound 1 exhibits a spin transition below room temperature, together with a very wide thermal hysteresis of about 50 K. This represents the widest hysteresis loop ever observed for an FeII-1,2,4-triazole spin transition material.
