Ergoline derivative LEK-8829-induced turning behavior in rats with unilateral striatal ibotenic acid lesions: interaction with bromocriptine. (1/2795)

LEK-8829 [9,10-didehydro-N-methyl-(2-propynyl)-6-methyl-8- aminomethylergoline bimaleinate] is an antagonist of dopamine D2 receptors and serotonin (5-HT)2 and 5-HT1A receptors in intact animals and a D1 receptor agonist in dopamine-depleted animals. In the present study, we used rats with unilateral striatal lesions with ibotenic acid (IA) to investigate the dopamine receptor activities of LEK-8829 in a model with innervated dopamine receptors. The IA-lesioned rats circled ipsilaterally when challenged with apomorphine, the mixed agonist on D1/D2 receptors. LEK-8829 induced a dose-dependent contralateral turning that was blocked by D1 receptor antagonist SCH-23390. The treatment with D1 receptor agonist SKF-82958 induced ipsilateral turning, whereas the treatment with D2 receptor antagonist haloperidol induced contralateral posture. The combined treatment with SKF-82958 and haloperidol resulted in a weak contralateral turning, indicating the possible receptor mechanism of contralateral turning induced by LEK-8829. Bromocriptine induced a weak ipsilateral turning that was blocked by haloperidol. The ipsilateral turning induced by bromocriptine was significantly potentiated by the coadministration of a low dose but not by a high dose of LEK-8829. The potentiation of turning was blocked either by SCH-23390 or by haloperidol. The potentiation of ipsilateral turning suggests the costimulation of D2 and D1 receptors by bromocriptine and LEK-8829, respectively, whereas the lack of potentiation by the highest dose of LEK-8829 may be explained by the opposing activity of LEK-8829 and bromocriptine at D2 receptors. We propose that the D2 and 5HT2 receptor-blocking and D1 receptor-stimulating profile of LEK-8829 is promising for the treatment of negative symptoms of schizophrenia.  (+info)

The carotid or vertebral selective injection of a total of 15 ml of non-ionic contrast media at 3 ml/sec over 5 seconds allows the selection of the "arterial phase". Four hundred sixty 3D angiographic studies were performed from December 1996 to September 1998 on 260 patients and have been analyzed in MIP (Maximum Intensity Projection) and SSD (Shaded Surface Display) views. The exploration of intracranial aneurysms is simplified and only requires, for each vascular axis, a biplane PA and Lateral run followed by a single rotational angiography run. The 3D angiography image is available on the workstation's screen (Advantage Workstation 3.1, GE Medical Systems) in less than 10 minutes after the acquisition of the rotational run. It therefore allows one to analyze, during the intervention, the aneurysm's angioarchitecture, in particular the neck, and select the best therapeutic technique. When endovascular treatment is the best indication, 3D angiography allows one to define the optimal angle of view and accurately select the microcoils dimensions. 3D angiography replaces the multiple oblique views that used to be required to analyze the complex aneurysms and therefore allows a reduction of the total contrast medium quantity, the patient X-ray dose and the length of the intervention time which is a safety factor. Also, in particular for complex cases, it brings additional elements complementing the results of standard 2D DSA and rotational angiograms. In the cervical vascular pathology, 3D angiography allows for a better assessment of the stenosis level and of dissection lesions. Our current research activities focus on the matching without stereotactic frame between 3D X-ray angiography and volumetric MR acquisition, which should allow us to improve the treatment of intracerebral arterio-venous malformations (AVMs).  (+info)

Recovery of the vestibulocolic reflex after aminoglycoside ototoxicity in domestic chickens. (3/2795)

Avian auditory and vestibular hair cells regenerate after damage by ototoxic drugs, but until recently there was little evidence that regenerated vestibular hair cells function normally. In an earlier study we showed that the vestibuloocular reflex (VOR) is eliminated with aminoglycoside antibiotic treatment and recovers as hair cells regenerate. The VOR, which stabilizes the eye in the head, is an open-loop system that is thought to depend largely on regularly firing afferents. Recovery of the VOR is highly correlated with the regeneration of type I hair cells. In contrast, the vestibulocolic reflex (VCR), which stabilizes the head in space, is a closed-loop, negative-feedback system that seems to depend more on irregularly firing afferent input and is thought to be subserved by different circuitry than the VOR. We examined whether this different reflex also of vestibular origin would show similar recovery after hair cell regeneration. Lesions of the vestibular hair cells of 10-day-old chicks were created by a 5-day course of streptomycin sulfate. One day after completion of streptomycin treatment there was no measurable VCR gain, and total hair cell density was approximately 35% of that in untreated, age-matched controls. At 2 wk postlesion there was significant recovery of the VCR; at this time two subjects showed VCR gains within the range of control chicks. At 3 wk postlesion all subjects showed VCR gains and phase shifts within the normal range. These data show that the VCR recovers before the VOR. Unlike VOR gain, recovering VCR gain correlates equally well with the density of regenerating type I and type II vestibular hair cells, except at high frequencies. Several factors other than hair cell regeneration, such as length of stereocilia, reafferentation of hair cells, and compensation involving central neural pathways, may be involved in behavioral recovery. Our data suggest that one or more of these factors differentially affect the recovery of these two vestibular reflexes.  (+info)

Projections and firing properties of down eye-movement neurons in the interstitial nucleus of Cajal in the cat. (4/2795)

To clarify the role of the interstitial nucleus of Cajal (INC) in the control of vertical eye movements, projections of burst-tonic and tonic neurons in and around the INC were studied. This paper describes neurons with downward ON directions. We examined, by antidromic activation, whether these down INC (d-INC) neurons contribute to two pathways: a commissural pathway to the contralateral (c-) INC and a descending pathway to the ipsilateral vestibular nucleus (i-VN). Stimulation of the two pathways showed that as many as 74% of neurons were activated antidromically from one of the pathways. Of 113 d-INC neurons tested, 44 were activated from the commissural pathway and 40 from the descending pathway. No neurons were activated from both pathways. We concluded that commissural and descending pathways from the INC originate from two separate groups of neurons. Tracking of antidromic microstimulation in the two nuclei revealed multiple low-threshold sites and varied latencies; this was interpreted as a sign of existence of axonal arborization. Neurons with commissural projections tended to be located more dorsally than those with descending projections. Neurons with descending projections had significantly greater eye-position sensitivity and smaller saccadic sensitivity than neurons with commissural projections. The two groups of INC neurons increased their firing rate in nose-up head rotations and responded best to the rotation in the plane of contralateral posterior/ipsilateral anterior canal pair. Neurons with commissural projections showed a larger phase lag of response to sinusoidal rotation (54.6 +/- 7.6 degrees ) than neurons with descending projections (45.0 +/- 5.5 degrees ). Most neurons with descending projections received disynaptic excitation from the contralateral vestibular nerve. Neurons with commissural projections rarely received such disynaptic input. We suggest that downward-position-vestibular (DPV) neurons in the VN and VN-projecting d-INC neurons form a loop, together with possible commissural loops linking the bilateral VNs and the bilateral INCs. By comparing the quantitative measures of d-INC neurons with those of DPV neurons, we further suggest that integration of head velocity signals proceeds from DPV neurons to d-INC neurons with descending projections and then to d-INC neurons with commissural projections, whereas saccadic velocity signals are processed in the reverse order.  (+info)

Modified Bankart procedure for recurrent anterior dislocation and subluxation of the shoulder in athletes. (5/2795)

Thirty-four athletes (34 shoulders) with recurrent anterior glenohumeral instability were treated with a modified Bankart procedure, using a T-shaped capsular incision in the anterior capsule. The inferior flap was advanced medially and/or superiorly and rigidly fixed at the point of the Bankart lesion by a small cancellous screw and a spike-washer. The superior flap was advanced inferiority and sutured over the inferior flap. Twenty-five athletes (median age: 22) were evaluated over a mean period of follow-up of 65 months. The clinical results were graded, according to Rowe, as 22 (88%) excellent, 3 (12%) good, and none as fair or poor. The mean postoperative range of movement was 92 degrees of external rotation in 90 degrees of abduction. Elevation and internal rotation was symmetrical with the opposite side. Twenty-four patients returned to active sport, 22 at their previous level. This modified Bankart procedure is an effective treatment for athletes with recurrent anterior glenohumeral instability.  (+info)

Transport of colloidal particles in lymphatics and vasculature after subcutaneous injection. (6/2795)

This study was designed to determine the transport of subcutaneously injected viral-size colloid particles into the lymph and the vascular system in the hind leg of the dog. Transport of two colloid particles, with average size approximately 1 and 0.41 microm, respectively, and with and without leg rotation, was tested. Leg rotation serves to enhance the lymph flow rates. The right femoral vein, lymph vessel, and left femoral artery were cannulated while the animal was under anesthesia, and samples were collected at regular intervals after subcutaneous injection of the particles at the right knee level. The number of particles in the samples were counted under fluorescence microscopy by using a hemocytometer. With and without leg rotation, both particle sets were rapidly taken up into the venous blood and into the lymph fluid. The number of particles carried away from the injection site within the first 5 min was <5% of the injected pool. Particles were also seen in arterial blood samples; this suggests reflow and a prolonged residence time in the blood. These results show that particles the size of viruses are rapidly taken up into the lymphatics and blood vessels after subcutaneous deposition.  (+info)

Hip moments during level walking, stair climbing, and exercise in individuals aged 55 years or older. (7/2795)

BACKGROUND AND PURPOSE: Low bone mass of the proximal femur is a risk factor for hip fractures. Exercise has been shown to reduce bone loss in older individuals; however, the exercises most likely to influence bone mass of the proximal femur have not been identified. Net moments of force at the hip provide an indication of the mechanical load on the proximal femur. The purpose of this study was to examine various exercises to determine which exercises result in the greatest magnitude and rate of change in moments of force at the hip in older individuals. SUBJECTS AND METHODS: Walking and exercise patterns were analyzed for 30 subjects (17 men, 13 women) who were 55 years of age or older (X = 65.4, SD = 6.02, range = 55-75) and who had no identified musculoskeletal or neurological impairment. Kinematic and kinetic data were obtained with an optoelectronic system and a force platform. Results. Of the exercises investigated, only ascending stairs generated peak moments higher than those obtained during level walking and only in the transverse plane. Most of the exercises generated moments and rate of change in moments with magnitudes similar to or lower than those obtained during gait. CONCLUSION AND DISCUSSION: Level walking and exercises that generated moments with magnitudes comparable to or higher than those obtained during gait could be combined in an exercise program designed to maintain or increase bone mass at the hip.  (+info)

Orientation-tuned spatial filters for texture-defined form. (8/2795)

Detection threshold for an orientation-texture-defined (OTD) test grating was elevated after adapting to an OTD grating of high orientation contrast. Threshold elevation was greatest for a test grating parallel to the adapting grating, and fell to zero for a test grating perpendicular to the adapting grating. We conclude that the human visual system contains an orientation-tuned neural mechanism sensitive to OTD form, and propose a model for this mechanism. We further propose that orientation discrimination for OTD bars and gratings is determined by the relative activity of these filters for OTD form.  (+info)

Rotational instability of the knee may persist after anterior cruciate ligament (ACL) reconstruction, which may be due to insufficiency of anterolateral stabilizing structures. However, no reliable diagnostic tool or physical examination test is available for identifying patients with anterolateral rotatory instability (ALRI). As shown in cadaveric studies, static internal rotation of the knee is increased in higher flexion angles of the knee after severing the anterolateral structures. This might also be the case in patients with an ACL-deficient knee and concomitant damage to the anterolateral structures. The objective of this study is to assess anterolateral rotatory instability of the knee during physical examination with a tibial internal rotation test. ACL-injured knees of 52 patients were examined by two examiners and side-to-side differences were compared. Both lower legs were internally rotated by applying manual internal rotation torque to both feet in prone position with the knees in 30°, 60
FUEL CELL SYSTEM AND METHOD OF CONTROLLING ROTATION SPEED OF COMPRESSOR - Even when the atmospheric pressure is lowered, a sufficient amount of oxidant gas is supplied to a fuel cell without causing any failure in a compressor. A control unit judges whether or not both the following conditions are satisfied: the accelerator opening degree detected by an accelerator opening degree sensor is equal to or larger than a predetermined opening degree; and the state where the atmospheric pressure detected by a pressure sensor is equal to or lower than a predetermined pressure value has been maintained for a predetermined time period or longer. If the judgment result is positive, the control unit changes the maximum rotation speed permitted in the compressor from a normal maximum rotation speed to an increased maximum rotation speed. The control unit then judges whether or not a predetermined time period has elapsed from when the maximum rotation speed was changed to the increased maximum rotation speed, ...

This is a group of three synovial joints that occur between the first two cervical vertebrae, the atlas and the axis. The altlanto-axial joint complex consists of two somewhat planar lateral joints between the articular facets of the lateral masses of the respective bones, and a median pivot joint where the dens of the axis fits into a fibro-osseous tunnel formed by the anterior arch and transverse ligament of the atlas. The principal motion at this joint is rotational movement in the transverse plane, as if one is shaking their head to say no. In addition to the transverse ligament mentioned above, the fibrous capsules of the lateral joints and the alar ligaments, which attach between the dens and the medial aspect of the occipital condyles, are primarily responsible for limiting the rotational movements of the joint ...

A drive mechanism for a medication delivery device is presented having a housing, a rotation member that rotates in a first direction with respect to the housing during setting of a dose of a medication and rotates in a second direction with respect to the housing during delivery of the dose, the second direction being opposite to the first direction. The device also has a piston rod that is displaced in a distal direction with respect to the housing for delivering the dose, a drive member which follows rotational movement of the rotation member in the second direction during delivery of the dose, and a stop member which prevents rotational movement of the drive member with respect to the housing in the first direction during setting of the dose.
A hand operated power tool comprising a housing with a motor and a working element performing an actuating movement if the tool is actuated. The motor is adapted to actuate a tool shaft in order to make it perform a rotational movement. A carrier element is functionally located between the tool shaft actuated by the motor and the working element for translating the rotational movement of the tool shaft into the actuating movement of the working element. In order to provide for a power tool, which allows perfect working of a workpiece with different types of actuating movements and/or working elements, it is suggested that the working element and the carrier element make part of a functional unit constituting a unit separate of the rest of the tool, wherein the functional unit is detachably fixed to the rest of the tool, in particular to the tool shaft.
Distance limiting self-retractable lifeline - A self-retractable lifeline (SRL) having the combination of an active fall arrest braking system and a passive restraint distance limiting mechanism that allows a user to pretension and preset the distance that its cable is capable of paying out. The SRLs cable limiting mechanism includes a pretension assembly, which may include a pair of aligned plates and an actuator that temporarily mobilizes an arbor when the lever is opened. The arbor is affixed to the SRL housing and to an interior of a power spring that rewinds the cable back into the housing when the cable is paid out. The other end of the arbor is in a mechanical relationship to one of the aligned plates that prohibits rotational movement of the arbor when the aligned plates are engaged but allows rotational movement of the arbor when the aligned plates are temporarily disengaged. When pretensioning of the power spring is desired, the actuator is activated and a tension is applied onto at ...

Voir la thèse. jeudi 31 janvier à 14 h 00 - Amphithéâtre Nougaro. Abstract :. This thesis investigates large scale flow rotation in two configurations. In the first, the effect of flow rotation on a laminar flame is investigated. The flame is anchored in the wake of a cylindrical bluff body. The flow rotation is introduced by turning the cylinder along its axis. It is shown by Direct Numerical Simulation (DNS), that the cylinder rotation breaks the symmetry of both flame branches. Flame Transfer Function (FTF) measurements performed by the Wiener-Hopf Inversion suggest, that low rotation rates lead to deep gaps in the gain and the flame becomes almost insensitive to acoustic perturbation at a specific frequency. It furthermore is demonstrated that this decrease in gain of the FTF is due to destructive interference of the heat release signals caused by the two flame branches. The frequency at which the gain becomes almost zero can be adjusted by tuning the cylinder rotation rate. The study ...

The effect of surface topography on the long-term development (≈10 weeks) of biofilms has been investigated using a monitoring technique based on images produced by a flat-bed scanner and initially developed for flat surfaces. The biofilm response to rotation speed changes in lab-scale rotating biological contactors (RBCs) has been studied. Two RBCs, each containing five discs (two with flat surfaces and three with rough surfaces) were run initially at two different rotation speeds: 4 rpm for reactor I and 40 rpm for reactor II. After 47 days, the rotation speed was increased in reactor I to 40 rpm and decreased in reactor II to 4 rpm. Prior to the rotation speed change, the biofilm on the flat discs underwent large detachments in both reactors, but the biofilm on rough discs was less extensively damaged. The increase in rotation speed induced large detachments of the biofilm in reactor I on all discs, but the biofilm on the rough discs recovered more effectively with faster regrowth. In reactor II,

We investigated the perception of self-rotation using constant-velocity chair rotations. Subjects signalled self motion during three independent tasks (1) by pushing a button when rotation was first sensed, when velocity reached a peak, when velocity began to decrease, and when velocity reached zero, (2) by rotating a disc to match the perceived motion of the body, or (3) by changing the static position of the dial such that a bigger change in its position correlated with a larger perceived velocity. All three tasks gave a consistent quantitative measure of perceived angular velocity. We found a delay in the time at which peak velocity of self-rotation was perceived (2-5 s) relative to the beginning or to the end of chair rotation. In addition the decay of the perception of self-rotation was preceded by a sensed constant-velocity interval or plateau (9-14 s). This delay in the rise of self-motion perception, and the plateau for the maximum perceived velocity, contrasts with the rapid rise and ...

The last few weeks I have been on rotation with Dr. Hae Mi Choe at the East Ann Arbor Ambulatory Care Clinic. It has been a great experience in part because I have never experienced amb care before but also because I have been able to accompany Dr. Choe on many of her administrative meetings. I have gained a greater understanding of how amb care clinics fit into the health-system. They serve an integral role in patient care as patients transition from hospital to home. The University of Michigan has a great model where pharmacists pair with physicians to help manage medication therapy on an outpatient basis. For example, we had a patient who was recently diagnosed with type 2 diabetes and her primary care physician sent her to the pharmacist to learn about her medications and glucometers. I spent about 30 minutes with the patient teaching her and her daughter how to measure blood sugar levels and she was very grateful for our time together. We will be following up with the patient over the next ...

Minimizing retinal image slip during locomotion is essential to maintain visual acuity (Angelaki and Hess, 2005; Angelaki and Cullen, 2008). For optimal performance, however, it is necessary that the spatiotemporal profile of gaze-stabilizing eye movements matches the organization and dynamics of the particular locomotory modality used. Although locomotion of terrestrial tetrapods with flexible necks generally requires relatively complex 3D eye movements to stabilize retinal images, the undulatory tail-based swimming of most aquatic vertebrates, such as larval Xenopus (Hoff and Wassersug, 1986; Azizi et al., 2007), necessitates only relatively simple paired (conjugate) ocular movements to counteract head rotational movements that are mainly in the horizontal plane. Indeed, such an eye motion profile has been recently observed during swimming in Xenopus tadpoles (Lambert et al., 2009, 2012), consistent with alternate burst discharge elicited in bilateral synergistic pairs of MR and LR motor ...
The origins of our inner ear lie hundreds of millions of years back in evolution, when primitive fish began to develop hollows in the skin that were sensitive to waves of pressure from water around them, as well as to waters movement as they pitched and rolled. With time the nerves became more refined, the hollows became tubes of seawater, and those tubes eventually closed off and buried themselves in the head. Further on in evolution, bones that were originally related to the jaw migrated and miniaturized, becoming the amplifying bones of the ear. The tubes dedicated to sensing rotational movement became our semicircular canals (balance), and its theorized that parts involved in sensing the pressure waves became our cochleas (hearing). In the composition of their salts, the fluids of our inner ear still carry the memory of that primordial ocean.. Within the human cochlea is a thin sensitive membrane, around thirty to thirty-five millimeters long, wound into a spiral and bathed in this salty ...

A self-contained conveyance or maneuvering device for mounting to the tongue platform of a trailer or the like which has a jack column and a ground-engaging wheel at the lower end thereof which can be vertically raised or lowered by power. The jack column is also rotatably power driven in either direction so as to direction orient the wheel. The wheel is reversibly power driven to move the platform and trailer. The vertical and rotational movement of the jack is accomplished by a single drive source which drives a tranmission which in turn is connected, respectively, to the drives for vertically translating the jack column, and for rotating it. The directions of movement and power applications are determined by a control circuit and control switches, the switches for controlling wheel direction and wheel reversible rotation being located in a hand control unit at the end of a length of electrical cable.
The connector pin assembly releasably retains telescoped excavating support and wear members in their telescoped relationship. The connector pin assembly is removably received in aligned connector openings in the members. A body portion of the assembly blocks removal of the wear member from the support member, and a lock member portion of the assembly is rotatable relative to the body, toward and away from a locking orientation, to releasably lock the body within the connector openings. A resilient sleeve having non-circular interior and exterior surfaces with rounded corners is non-slippably disposed over a rotatable shaft of the lock member in order to slidingly and deformably engage a non-circular shaped interior cavity of the body that rotatably receives shaft and sleeve of the lock member. The sleeve yieldingly resists rotational movement of the lock member away from a locking orientation.
Visual and non-visual cues, both static and dynamic, affect perception of body orientation relative to gravity. Prior research has investigated the relative influence of static orientation and dynamic rotation vestibular signals (from the otoliths and canals, respectively) on perceived body roll. We used a cue-conflict paradigm to directly compare the influence of static orientation and dynamic rotation visual cues. Vestibular stimulation was provided by rolling the subject. Visual stimulation was provided by a stereo display attached to the rolling device. Subjects set a visible rod to earth-vertical after being rolled to the target angle. In static conditions, the visual scene appeared only when the target angle was reached. In dynamic conditions, a rotating scene was visible throughout. The speed of the visual rotation was varied relative to the speed of the body rotation. Four visual scenes were used: 1) dynamic room scene; 2) static room; 3) static cube; 4) dynamic random-dot cloud. ...

Time experts are not sure why this should be so, but they have some ideas. Thomas R. OBrian, who heads NISTs Time & Frequency Division, Boulder, Colo., says the speed of the Earths rotation in the long term has tended to slow, but not during the past five years. The reasons, OBrian suggests, include changes in the motion of the Earths core, the effects of ocean tides and weather, and changes in the shape of the Earths magnetic field. He says most scientists expect the Earths spin to continue to slow in the future. OBrian says: The Earths rotation rate has been the primary clock for nearly all of human history. ...

Use the following table to supplement your rotations in preparation for residency in PM&R:. ...
Different modalities have been used to describe the rotational motion of the ventricles of the heart and studies have indicated LV twist to be an additional integral component in LV function. So far, only amplitudes and timings of rotation have been reported, whereas no method is available to fully describe the rotation pattern of the ventricles. The object of the present application is to achieve a system that presents a novel way to quantify and visualize the ventricular rotation pattern of the heart. We present a novel method that assesses and describes the rotation pattern by calculating the rotation axis of the ventricle. Non- invasive image acquisition is required to collect rotation values from different positions of the myocardium. Thereafter, a kinematic model of a ventricle is constructed to determine the rotation planes at different levels of the heart. The motion of the rotation planes are visualized by plotting the normal vectors of the planes over time, i.e. the rotation axis of ...
Regulation of the direction of flagellar rotation is central to the mechanism of bacterial chemotaxis. The transitions between counterclockwise and clockwise rotation are controlled by a switch complex composed of three proteins (FliG, FliM, and FliN) and located at the base of the flagellar motor. The mechanism of function of the switch is unknown. Here we demonstrate that the diffusible clockwise-signal molecule, the CheY protein, binds to the switch, that the primary docking site is FliM, that the extent of CheY binding to FliM is dependent upon the phosphorylation level of CheY, and that it is unaffected by the other two switch proteins. This study provides a biochemical demonstration of binding of a signal molecule to the bacterial switch and demonstrates directly that phosphorylation regulates the activity of this molecule ...

We show how to implement stick boundary conditions for a spherical colloid in a solvent that is coarse-grained by the method of stochastic rotation dynamics. This allows us to measure colloidal rotational velocity auto-correlation functions by direct computer simulation. We find quantitative agreement with Enskog theory for short times and with hydrodynamic mode-coupling theory for longer times. For aqueous colloidal suspensions, the Enskog contribution to the rotational friction is larger than the hydrodynamic one when the colloidal radius drops below 35 nm.
The possibility of causing adverse changes in patients profile as a result of mandibular displacement still causes concern in indicating maxillary expansions [8]. Clockwise rotation of the mandible with an increase in lower facial height has been reported as a side effect of SARME [6, 9]. In fact, our study found a clockwise rotation of the mandible immediately after SARME. This movement was represented by an increase in the values of the FMA as well as downward and backward displacements of the menton.. However, according to our results, the mandibular rotation seems to be a transient movement as the values observed 6 months after SARME (T3) tended to return close to their initial values (T1). Altug-Atac et al. [6] and Gunbay et al. [9] reported clockwise rotation of the mandible after SARME whereas Parhiz et al. [4] and Iodice et al. [10] did not observe significant rotational movement of the mandible. Methodological differences among these studies and assessment in different time points ...
We experimentally generated superpositions of higher-order Bessel beams that possess no global orbital angular momentum (OAM), yet exhibit an angular rotation in their intensity profile as the field propagates. The digital holograms encoded on a spatial light modulator (SLM), used for generating such fields, consist of two annular rings of unequal radial wave-vectors where each ring is encoded with an azimuthal mode of equal order but opposite charge. We present experimentally measured angular rotation rates for some example superposition fields, which are shown to be in good agreement with that predicted theoretically. Introducing a second SLM and a Fourier transforming lens, we demonstrate a simple approach to perform an azimuthal decomposition of our generated optical fields. Bounding the match-filter to an annular ring, of varying radius, we are able to perform a scale-independent azimuthal decomposition of our initial field. From the measured weightings of the azimuthally decomposed modes ...

During systole, the left ventricle twists around its long axis. This aids in the ejection of blood from the ventricle. Therefore, rotation and torsion are important factors in cardiac mechanics. Typically, a healthy left ventricle will rotate counterclockwise in the apical region and clockwise in the basal region with a net angle of 13 to 27 degrees.. Observations in a cohort of 30 heart failure patients with left bundle branch block (LBBB) show an abnormal twisting motion. To better understand the underlying mechanisms of this abnormal rotation behaviour, an in-silico study on (bi)ventricular, patient specific models will be conducted. Hence, we first create patient specific ventricular geometries from MRI data and perform (electro-)mechanical simulations.. ...

An intramedullar osteosynthetic device includes a body with an elongated shape and a flat cross-section having, in succession, from one of its ends, a first fixation zone cooperating with one of the bone parts to be immobilised, a median zone suitable for withstanding the shear and bending stresses, and a second fixation zone in the other bone part to be immobilised. Each of the fixation zones is made from a material suitable for enabling their deformation by thermal action (tepid memory) or mechanical action (superelasticity), to permit an introduction into the bone parts without pulpar approach, followed by a fixation in the bone parts, while avoiding any rotational movement, withstanding the tensile stresses, and maintaining a compressive force. At least one of the fixation zones has two tabs or fins and which are separable under the effect of the deformation.

So how do you become more relaxed when your natural propensity is be stiff and tense? Well one suggestion that is working for me involves looking at how they do it in the softer martial arts. Like I have mentioned before, my kobudo training is done in a jujitsu club and much of it is based on the principles of jujitsu, which is a soft martial art. Movements are generally slower and circular rather than fast and linear. To move in a more circular way requires you to be more relaxed and to understand how push/pull and rotational movements affect ukes responses ...

A baby bottle equipped with a uniquely effective bottle nipple shield is provided which permits continuous access by the child to the contents of the bottle while simultaneously protecting the nipple from contamination if the bottle is dropped on a surface. In the preferred construction, the nipple shield of the bottle of the invention includes a generally planar base member which defines a central bore in substantially coaxial relation to the nipple proper and which mounts a pair of wing members which project generally upwardly from the base member in spaced apart relation to each other and in substantially parallel relation to the principal axis of the nipple. The projecting wing members terminate with their respective upper free ends position in fixed spaced apart relation to one another so that continuous access to the nipple is enabled. In a particular preferred construction, the projecting wing members are configured in a lobular shape which protects the nipple through rotational movements

To reach and grasp an object in space on the basis of its image cast on the retina requires different coordinate transformations that take into account gaze and limb positioning. Eye position in the orbit influences the images conversion from retinotopic (eye-centered) coordinates to an egocentric frame necessary for guiding action. Neuroimaging studies have revealed eye position-dependent activity in extrastriate visual, parietal and frontal areas that is along the visuo-motor pathway. At the earliest vision stage, the role of the primary visual area (V1) in this process remains unclear. We used an experimental design based on pattern-onset visual evoked potentials (VEP) recordings to study the effect of eye position on V1 activity in humans. We showed that the amplitude of the initial C1 component of VEP, acknowledged to originate in V1, was modulated by the eye position. We also established that putative spontaneous small saccades related to eccentric fixation, as well as retinal disparity cannot
Proxima Centauri b is the closest exoplanet to Earth. It is only four light years away. However, since Proxima Centauri b is much closer to its star than Earth, there is a high probability that it is tidally locked, much like our Moon, where one side always faces the Earth.
The last two basic movements are segment rotations. Rotations can be either medial (also known as internal), and lateral (also known as external). These type of rotations are best described around shoulder movements. If you place your palm flat on your stomach, your arm (humerus) is said to be medially rotated. If you then, while in the same position, keep your elbow close to your waist and gradually take your palm away from your stomach you are laterally rotating your arm. This medial/lateral rotation described above all takes place at the shoulder joint. See the 4 different types of joints ...

Contralateral oblique X-ray of the sacroiliac joint. The anterior and posterior joint lines aligned to form a crisp silhouette of the joint.. The C-arm is rotated and adjusted until the medial cortical line of the medial silhouette is maximally crisp, which coincides with the beam directed into the posterior opening of the inferior joint space. Usually, this view is obtained with 5-20° of contralateral rotation.. A 22- or 25-gauge spinal needle is used and directed toward initially to the sacrum first to appreciate the depth required. Once the bone is contacted, the needle is redirected toward the joint line. The operator should note the depth of the initial contact so that the needle should not penetrate a few more millimeters deeper than this depth.. Once the needle has entered the joint space, 0.3-0.5 mL of contrast is injected. In posteroanterior view, the contrast material should be seen traveling rostral along the joint (Fig. 48.7 ). A lateral X-ray should be used to confirm the needle ...
When thinking about the top ten pitchers in baseball, there are two Cubs starters who I think are just outside that group. Maybe in it.
The shape functions therefore become multi-dimensional embeddings in the physical domains on the respective finite elements, generally spanning the dimensions associated with multiple degrees of freedom. On the Lie algebra, which is, by its mathematical construction, a vector space, rotations can be represented as translations, and it is this aspect which makes this approach particularly interesting for finite-element calculations that involve the modelling of rotations. In established finite element methods, translations and rotations are assigned different degrees of freedom (d.o.f.). Often, the components of the interpolant between two or more nodes belonging to a given finite element are then constructed separately on the basis the individual degrees of freedom, thus eliminating the interplay between translations and rotations that can be observed in the physical reality. Well-known deficiencies of many of these formulations, such as lack of geometric invariance, path dependence and ...

Aims: To investigate the ability of patients with Parkinsons disease to perform a rotation around the longitudinal axis of the body. Three questions were raised. Is body rotation impaired in Parkinsons disease? Is there a level of the kinematic chain from the head to the foot at which the impairment is more severe? Is the deficit related to the general slowness of movement in Parkinsons disease?. Methods: Kinematic data were recorded. The temporal organisation of body rotation during gait initiation was analysed in 10 patients with Parkinsons disease, who were all at an advanced stage of the disease and had all experienced falls and freezing during their daily life, and in five controls. The latency of the onset of the rotation of each segment was measured by taking the onset of the postural phase of step initiation as reference value. Locomotor variables were also analysed.. Results: Body rotation was found to be impaired in patients with Parkinsons disease, as the delay in the onset of ...
For residents, immunology and renal pathology rotations are combined. In immunology the residents learn how to work up a patient with an autoimmune or a paraproteinemic disorder and how these systemic orders adversely affect various target organs, for instance, the kidney. Very often the electrophoresis gels and ANCA and ANA slides are discussed with Medical Technitians for educational purposes before the reports are finalized. The residents on rotation review various tutorials in the immunology laboratory. In addition, the residents receive four to six didactic lectures on Immunology/Renal Pathology during the two to three weeks of rotation. All the native renal biopsies are reviewed with medical students, nephrology residents and fellows and the attending staff. ...

Case Study. A 30-year-old male inter-county hurler presented to the clinic with bilateral hip pain, with symptom duration of three years. The patient had a history in keeping with femoroacetabular impingement (FAI), and reported pain while twisting and turning and substantial stiffness following activity, although was still engaged in full training and competition. His symptoms had failed to resolve with conservative management. Upon assessment, the patient had a positive FADIR (flexion, adduction and internal rotation) test and had radiological signs indicative of FAI. The patient was subsequently assessed on all of the functional assessments mentioned above and displayed lower levels of acceleration, agility and range of motion (ROM) compared to the average healthy control group scores. The patient underwent bilateral arthroscopic hip surgery for the correction of FAI (one week apart): The abnormal, bony deformity was resected using a mechanical burr, restoring the normal contour of the ...
Spectia of sixty-seven H Ir regions from 3 to 24 kpc from the nucleus of M31 have been obtained with the DTM image-tube spectrograph at a dispersion of 135 A mm . Radial velocities, principally from Ha, have been determined with an accuracy of 10 km sec for most regions. Rotational velocities have been calculated under the assumption of circular motions only. For the region interior to 3 kpc where no emission regions have been identified, a narrow [N 13] x6583 emission line is observed. Velocities from this line indicate a rapid rotation in the nucleus, rising to a maximum circular velocity of V = 225 km at R = 400 pc, and falling to a deep minimum near R = 2 kpc. From the rotation curve for R < 24 kpc, the following disk model of M31 results. There is a dense, rapidly rotating nucleus of mass Al = (6 i 1) x 10 Alo. Near R = 2 kpc, the density is very low and the rotational motions are very small. In the region from 500 to 1.4 kpc (most notably on the southeast minor axis), gas is observed

by An H, Zhang Y, Yuan H, et al. on August 11, 2021 at 12:00 am AbstractCable-driven parallel robots (CDPRs) have the characteristic of easy deployment, which endows CDPRs with flexible workspace, freely configurable degrees-of-freedom (DOFs), and various configurations, greatly expanding their range of applications. Modular design provides excellent convenience and feasibility for deployment, which is a crucial issue of CDPR design. A highly integrated cable-driving module is designed in this paper, which includes the winding bobbin, servo motor, force sensor, external encoder, electromagnetic brake, as well as other devices. Experiments show that the maximum cable length control error is less than 0.16%, and the maximum cable tension control error is less than 8% in the back-and-forward rotation test. Furthermore, a CDPR with eight cables and six DOFs is constructed rapidly using the proposed module, whose dimension is 850 × 850 × 650 mm3. Results show that the robots trajectory errors are ...

Ive always been wondering about this ever since I watched figure skating. I know majority of skaters rotate counter clockwise when they are executing their jumps, and there are few who executes clockwise. Whats the reason for them to turn clockwise? Are certain jumps easier/harder when doing clockwise (compared to counter clockwise)? I know there are skaters like Caro, Wagner, and Weir who turns clockwise. Which skaters in the past, (before CoP era) turned clockwise?
Abstract: We have performed the first 3-dimensional simulations of strong first-order thermal phase transitions in the early Universe. For deflagrations, we find that the rotational component of the fluid velocity increases as the transition strength is increased. For detonations, however, the rotational velocity component remains constant and small. We also find that the efficiency with which kinetic energy is transferred to the fluid falls below theoretical expectations as we increase the transition strength. The probable origin of the kinetic energy deficit is the formation of reheated droplets of the metastable phase during the collision, slowing the bubble walls. The rate of increase in the gravitational wave energy density for deflagrations in strong transitions is suppressed compared to that predicted in earlier work. This is largely accounted for by the reduction in kinetic energy. Current modelling therefore substantially overestimates the gravitational wave signal for strong ...
We came across this interesting thread on the BBC website which refers to a lecture given by Professor David Nutt, of the Advisory Council on the Misuse of Drugs.
