[Repetitive transcranial magnetic stimulation in major depression: response factor].

Objective: Repetitive transcranial magnetic stimulation (rTMS) is a brain stimulation technique that has been investigated as a novel treatment for psychiatric disorders, notably in major depression, and has shown statistically significant effects. The authors found it necessary to propose an up-to-date review of positive predictors for antidepressive response to repetitive transcranial magnetic stimulation.

Method: Based on an exhaustive consultation of Medline data, supplemented by a manual research, only works evaluating response factors of rTMS in major depression were retained.

In-plane magnetic anisotropy and temperature dependence of switching field in (Ga, Mn) as ferromagnetic semiconductors.

Improvement of health-related quality of life in depression after transcranial magnetic stimulation in a naturalistic trial is associated with decreased perfusion in precuneus.

Background: Assessing Health-related Quality of life (HRQoL) is necessary to evaluate care and treatments provided to patients with major depressive disorder (MDD), in addition to the traditional assessment of clinical outcomes. However, HRQoL remains under-utilized to assess the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in research or in a routine clinical setting. The primary objective of this exploratory study on MDD was to investigate the impact of low-frequency rTMS on HRQoL using the SF-36 questionnaire.

Potential of the pseudo-inverse method as a constrained static optimization for musculo-tendon forces prediction.

Inverse dynamics combined with a constrained static optimization analysis has often been proposed to solve the muscular redundancy problem. Typically, the optimization problem consists in a cost function to be minimized and some equality and inequality constraints to be fulfilled. Penalty-based and Lagrange multipliers methods are common optimization methods for the equality constraints management.

Inhibition of p-aminobenzoate and folate syntheses in plants and apicomplexan parasites by natural product rubreserine.

Glutamine amidotransferase/aminodeoxychorismate synthase (GAT-ADCS) is a bifunctional enzyme involved in the synthesis of p-aminobenzoate, a central component part of folate cofactors. GAT-ADCS is found in eukaryotic organisms autonomous for folate biosynthesis, such as plants or parasites of the phylum Apicomplexa. Based on an automated screening to search for new inhibitors of folate biosynthesis, we found that rubreserine was able to inhibit the glutamine amidotransferase activity of the plant GAT-ADCS with an apparent IC(50) of about 8 μM.

Biochemical and structural characterization of the Arabidopsis bifunctional enzyme dethiobiotin synthetase-diaminopelargonic acid aminotransferase: evidence for substrate channeling in biotin synthesis.

Diaminopelargonic acid aminotransferase (DAPA-AT) and dethiobiotin synthetase (DTBS) catalyze the antepenultimate and the penultimate steps, respectively, of biotin synthesis. Whereas DAPA-AT and DTBS are encoded by distinct genes in bacteria, in biotin-synthesizing eukaryotes (plants and most fungi), both activities are carried out by a single enzyme encoded by a bifunctional gene originating from the fusion of prokaryotic monofunctional ancestor genes. In few angiosperms, including Arabidopsis thaliana, this chimeric gene (named BIO3-BIO1) also produces a bicistronic transcript potentially encoding separate monofunctional proteins that can be produced following an alternative splicing mechanism.

3D kinematic of bunched, medium and elongated sprint start.

The aim of this study was to test the influence of 3 different horizontal distances between the blocks (bunched, medium and elongated) on the velocity of the centre of mass (VCM) and the kinetic energy (KE) of the body segments and of the whole body. 9 well-trained sprinters performed 4 maximal 10 m sprints. An opto-electronic Motion Analysis® system (12 digital cameras 250 Hz) was used to collect the 3D trajectories of 63 markers during the starting block phase.

Influence of joint models on lower-limb musculo-tendon forces and three-dimensional joint reaction forces during gait.

Several three-dimensional (3D) lower-limb musculo-skeletal models have been developed for gait analysis and different hip, knee and ankle joint models have been considered in the literature. Conversely to the influence of the musculo-tendon geometry, the influence of the joint models--i.e.

Anesthesia for cesarian section in pregnant woman with acute intermittent porphyria and hypothyroidism--case report.

Acute intermittent porphyria (AIP) is a rare autosomal dominant metabolic disorder' affecting the production of heme, the oxygen-binding prosthetic group of hemoglobin. It is characterized by a deficiency of the enzyme hydroxymethylbilane synthase; without this cytoplasmic enzyme, heme synthesis cannot finish, and the metabolite porphobilinogen accumulates in the cytoplasm. Some additional factors must also be present such as drugs, hormones, dietary changes, infections diseases and surgery that trigger the appearance of symptoms, which include neurological disorders, abdominal pain, constipation, and muscle weakness.

Sagittal spine posture assessment: feasibility of a protocol based on intersegmental moments.

Evaluation of spinal posture has recently benefited from the contribution of three-dimensional reconstruction technologies that have helped improve our understanding of this dynamic balance. The aim of this study was to present the preliminary results of a three-dimensional protocol to analyze postural balance. This analytical method is not limited by certain constraints of the radiological approach and evaluates postural balance using a new approach taking into account the net efforts of different intersegmental centers.

Outcomes of primary surveillance for intraductal papillary mucinous neoplasm.

Background: Limited data are available regarding the natural history of patients undergoing primary surveillance for intraductal papillary mucinous neoplasm (IPMN). We hypothesize that symptoms, radiologic characteristics, and cytopathology will predict cancer risk during surveillance.

Methods: Between March 2002 and March 2010, 522 patients were diagnosed with IPMN at a single, high-volume institution.

The many faces of aspartate kinases.

Based on recent X-ray structures and biochemical characterizations of aspartate kinases from different species, we show in this review how various organizations of a regulatory domain have contributed to the different mechanisms of control observed in aspartate kinases allowing simple to complex allosteric controls in branched pathways. The aim of this review is to show the relationships between domain organization, effector binding sites, mechanism of inhibition and regulatory function of an allosteric enzyme in a biosynthetic pathway.

4-hydroxyphenylpyruvate dioxygenase catalysis: identification of catalytic residues and production of a hydroxylated intermediate shared with a structurally unrelated enzyme.

4-Hydroxyphenylpyruvate dioxygenase (HPPD) catalyzes the conversion of 4-hydroxyphenylpyruvate (HPP) into homogentisate. HPPD is the molecular target of very effective synthetic herbicides. HPPD inhibitors may also be useful in treating life-threatening tyrosinemia type I and are currently in trials for treatment of Parkinson disease.

Effect of axis alignment on in vivo shoulder kinematics.

BACKGROUND. To describe 3D shoulder joint movements, the International Society of Biomechanics (ISB) recommends using segment coordinate systems (SCSs) on the humerus, scapula and thorax, and joint coordinate systems (JCSs) on the shoulder. However, one of the remaining problems is how to define the zero angles when the arm is in an initial reference position.

Foot mechanics during the first six years of independent walking.

Recognition of the changes during gait that occur normally as a part of growth is essential to prevent mislabeling those changes from adult gait as evidence of gait pathology. Currently, in the literature, the definition of a mature age for ankle joint dynamics is controversial (i.e.

[Affective disorders and repetitive transcranial magnetic stimulation: Therapeutic innovations].

Depression is the most common psychiatric disorder with a particularly important disability due to its evolution to chronicity and treatment-resistance. In the same way, the outcome of bipolar disorder is similar. Only 75% subjects remain remitted in the year following the onset of mood episode and depressive episode leads to worth responsiveness than patients in phase hypo/manic.
