The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation.

Plaque area increase and vascular remodeling contribute to lumen area change after percutaneous transluminal angioplasty of the femoropopliteal artery: an intravascular ultrasound study. (1/356)

OBJECTIVE: The aim of the study was to assess the change in lumen area (LA), plaque area (PLA), and vessel area (VA) after percutaneous transluminal angioplasty (PTA) of the femoropopliteal artery. METHODS: This was a prospective study. Twenty patients were studied with intravascular ultrasound (IVUS) immediately after PTA and at follow-up examination. Multiple corresponding IVUS cross-sections were analyzed at the segments that were dilated by PTA (ie, treated sites; n = 168), including the most stenotic site (n = 20) and the nondilated segments (ie, reference sites; n = 77). RESULTS: At follow-up examination, both the PLA increase (13%) and the VA decrease (9%) resulted in a significant LA decrease (43%) at the most stenotic sites (P =.001). At the treated sites, the LA decrease (15%) was smaller and was caused by the PLA increase (15%). At the reference sites, the PLA increase (15%) and the VA increase (6%) resulted in a slight LA decrease (3%). An analysis of the IVUS cross-sections that were grouped according to LA change (difference >/=10%) revealed a similar PLA increase in all the groups: the type of vascular remodeling (VA decrease, no change, or increase) determined the LA change. At the treated sites, the LA change and the VA change correlated closely (r = 0.77, P <.001). At the treated sites, significantly more PLA increase was seen in the IVUS cross-sections that showed hard lesion or media rupture (P <.05). No relationship was found between the presence of dissection and the quantitative changes. CONCLUSION: At the most stenotic sites, lumen narrowing was caused by plaque increase and vessel shrinkage. Both the treated sites and the reference sites showed a significant PLA increase: the type of vascular remodeling determined the LA change at follow-up examination. The extent of the PLA increase was significantly larger in the IVUS cross-sections that showed hard lesion or media rupture.  (+info)

Prenatal diagnosis of a lean umbilical cord: a simple marker for the fetus at risk of being small for gestational age at birth. (2/356)

OBJECTIVE: The purpose of this study was to investigate whether the prenatal diagnosis of a 'lean' umbilical cord in otherwise normal fetuses identifies fetuses at risk of being small for gestational age (SGA) at birth and of having distress in labor. The umbilical cord was defined as lean when its cross-sectional area on ultrasound examination was below the 10th centile for gestational age. METHOD: Pregnant women undergoing routine sonographic examination were included in the study. Inclusion criteria were gestational age greater than 20 weeks, intact membranes, and singleton gestation. The sonographic cross-sectional area of the umbilical cord was measured in a plane adjacent to the insertion into the fetal abdomen. Umbilical artery Doppler waveforms were recorded during fetal apnea and fetal anthropometric parameters were measured. RESULTS: During the study period, 860 patients met the inclusion criteria, of whom 3.6% delivered a SGA infant. The proportion of SGA infants was higher among fetuses who had a lean umbilical cord on ultrasound examination than among those with a normal umbilical cord (11.5% vs. 2.6%, p < 0.05). Fetuses with a lean cord had a risk 4.4-fold higher of being SGA at birth than those with a normal umbilical cord. After 25 weeks of gestation, this risk was 12.4 times higher when the umbilical cord was lean than when it was of normal size. The proportion of fetuses with meconium-stained amniotic fluid at delivery was higher among fetuses with a lean cord than among those with a normal umbilical cord (14.6% vs. 3.1%, p < 0.001). The proportion of infants who had a 5-min Apgar score < 7 was higher among those who had a lean cord than among those with normal umbilical cord (5.2% vs. 1.3%, p < 0.05). Considering only patients admitted in labor with intact membranes and who delivered an appropriate-for-gestational-age infant, the proportion of fetuses who had oligohydramnios at the time of delivery was higher among those who had a lean cord than among those with a normal umbilical cord (17.6% versus 1.3%, p < 0.01). CONCLUSION: We conclude that fetuses with a lean umbilical cord have an increased risk of being small for gestational age at birth and of having signs of distress at the time of delivery.  (+info)

Velocity associated characteristics of force production in college weight lifters. (3/356)

OBJECTIVE: To determine velocity specific isokinetic forces and cross sectional areas of reciprocal muscle groups in Olympic weight lifters. METHODS: The cross sectional area of the flexor or extensor muscles of the elbow or knee joint was determined by a B-mode ultrasonic apparatus in 34 college weight lifters and 31 untrained male subjects matched for age. Maximum voluntary force produced in the flexion and extension of the elbow and knee joints was measured on an isokinetic dynamometer at 60, 180, and 300 degrees/s. RESULTS: The average cross sectional area was 31-65% higher, and the force was 19-62% higher in weight lifters than in the untrained subjects. The ratio of force to cross sectional area was the same in both groups. The weight lifters showed a lower velocity associated decline in force than untrained subjects in the elbow and knee flexors but not in the extensors. CONCLUSIONS: These results indicate that for muscle contractions with velocities between 60 degrees/s and 300 degrees/s the difference in isokinetic force between weight lifters and untrained subjects can be primarily attributed to the difference in the muscle cross sectional area. However, the lower velocity associated decline in force implies that weight lifters may have a higher force per cross sectional area than untrained subjects at velocities above 300 degrees/s.  (+info)

Sonographic incidence of tendon microtears in athletes with chronic Achilles tendinosis. (4/356)

OBJECTIVE: To assess the number and distribution of tendon microtears in asymptomatic controls and athletes with chronic Achilles tendinitis or partial thickness tears using high resolution ultrasound. METHODS: The mean number of microtears in three random tendon cross sections were recorded per tendon third in 19 asymptomatic volunteers, 16 athletes with symptomatic chronic Achilles tendinitis, and eight athletes with partial Achilles tendon rupture. RESULTS: Microtears were most numerous in the middle third section of the Achilles tendon. Some 67% of tendons in the control group had no microtears, and 28% showed a single microtear. Only 18% of the athletes with chronic Achilles tendinitis and none of the athletes with partial tendon rupture were without microtears in the middle third of their Achilles tendon. Of the tendons with chronic tendinitis, 13% had more than three microtears per section which increased to 87% in tendons exhibiting partial rupture. CONCLUSIONS: There appears to be an association between microtear formation and Achilles tendon rupture.  (+info)

Angiographic abnormalities in progressive multifocal leukoencephalopathy: an explanation based on neuropathologic findings. (5/356)

BACKGROUND AND PURPOSE: Progressive multifocal leukoencephalopathy (PML) is typically occult at angiography and fails to enhance on MR images. After observing angiographic abnormalities characterized by arteriovenous shunting and pathologic parenchymal blush in patients with AIDS-related PML, often in the absence of contrast enhancement on MR images, we hypothesized that there might be distinct changes in the cerebral microvasculature that account for the reduction in vascular transit time (arteriovenous shunting) in the absence of blood-brain barrier dysfunction. METHODS: The imaging studies and neuropathologic specimens of six patients with biopsy-proved PML were reviewed retrospectively. In all patients contrast-enhanced MR imaging and CT, followed by cerebral angiography, were performed before stereotactically directed biopsy. The angiograms were evaluated for the presence of vascular displacement, pathologic parenchymal blush, arteriovenous shunting, and neovascularity. The CT and MR studies were reviewed for the presence of enhancement of the PML lesions. Biopsy specimens were examined for the presence of necrosis, perivascular inflammation, and neovascularity. RESULTS: All patients had oligodendrocytic intranuclear inclusions diagnostic of PML, together with perivascular inflammation and neovascularity to a varying extent; no other neuropathologic processes were identified. Angiographic abnormalities, characterized by a pathologic parenchymal blush and arteriovenous shunting, were identified in four of the six patients. In only one of these cases, however, was abnormal enhancement identified on cross-sectional imaging studies (MR and CT), and this patient had florid perivascular inflammatory infiltrates histologically. CONCLUSION: The pathologic parenchymal blush and arteriovenous shunting seen angiographically in some patients with PML reflect small-vessel proliferation and perivascular inflammatory changes incited by the presence of the JC virus in infected oligodendrocytes.  (+info)

Anatomical information in radiation treatment planning. (7/356)

We report on experience and insights gained from prototyping, for clinical radiation oncologists, a new access tool for the University of Washington Digital Anatomist information resources. This access tool is designed to integrate with a radiation therapy planning (RTP) system in use in a clinical setting. We hypothesize that the needs of practitioners in a clinical setting are different from the needs of students, the original targeted users of the Digital Anatomist system, but that a common knowledge resource can serve both. Our prototype was designed to help define those differences and study the feasibility of a full anatomic reference system that will support both clinical radiation therapy and all the existing educational applications.  (+info)

The Virtual Pelvic Floor, a tele-immersive educational environment. (8/356)

This paper describes the development of the Virtual Pelvic Floor, a new method of teaching the complex anatomy of the pelvic region utilizing virtual reality and advanced networking technology. Virtual reality technology allows improved visualization of three-dimensional structures over conventional media because it supports stereo vision, viewer-centered perspective, large angles of view, and interactivity. Two or more ImmersaDesk systems, drafting table format virtual reality displays, are networked together providing an environment where teacher and students share a high quality three-dimensional anatomical model, and are able to converse, see each other, and to point in three dimensions to indicate areas of interest. This project was realized by the teamwork of surgeons, medical artists and sculptors, computer scientists, and computer visualization experts. It demonstrates the future of virtual reality for surgical education and applications for the Next Generation Internet.  (+info)

The sectional area of the splenotomogram scanned parallel to the ribs provides useful information for differential diagnosis and determination of prognosis in liver diseases. To establish a relationship between sectional area and actual spleen volume, 10 spleens obtained at splenectomy or autopsy were studied. A good linear correlation (r = 0.956) was present between the sectional area (S) and the actual spleen volume (V). The spleen volume could be calculated as V = 7.5S - 77.5. Therefore the value of the sectional area obtained from one ultrasonic splenotomogram has practical application as a parameter reflecting the spleen volume in vivo. ...
Pendrin is a Cl-/HCO3- exchanger expressed in the apical regions of renal intercalated cells. Following pendrin gene ablation, blood pressure falls, in part, from reduced renal NaCl absorption. We asked if pendrin is expressed in vascular tissue and if the lower blood pressure observed in pendrin null mice is accompanied by reduced vascular reactivity. Thus, the contractile responses to KCl and phenylephrine (PE) were examined in isometrically mounted thoracic aortas from wild-type and pendrin null mice. Although pendrin expression was not detected in the aorta, pendrin gene ablation changed contractile protein abundance and increased the maximal contractile response to PE when normalized to cross sectional area (CSA). However, the contractile sensitivity to this agent was unchanged. The increase in contractile force/cross sectional area observed in pendrin null mice was due to reduced cross sectional area of the aorta and not from increased contractile force per vessel. The pendrin-dependent ...
Objective: To establish a bedside test with ultrasonography for evaluation of foot muscle atrophy in diabetic patients.. Research Design and Methods: Thickness and cross sectional area of the extensor digitorum brevis muscle (EDB) and of the muscles of the first interstitium (MIL) were determined in 26 diabetic patients and in 26 matched control subjects using ultrasonography. To estimate the validity findings were related to the total volume of all foot muscles determined at magnetic resonance imaging (MRI-FMvol). Furthermore, the relations of ultrasonographic estimates to nerve conduction, sensory perception tresholds and clinical condition were established.. Results: In diabetic patients the ultrasonographic thickness of EDB (U-EDBt) was 6.4 ± 2.1 mm (mean ± SD) vs. 9.0 ± 1.0 mm in controls (p,0.001), thickness of MIL (U-MILt) was 29.6 ± 8.3 mm vs. 40.2 ± 3.6 mm in controls (p,0.001) and the cross sectional area of EDB (U-EDBCSA) was 116 ± 65 mm2 vs. 214 ± 38 mm2 in controls (p,0.001). ...
The extent of luminal narrowing varies with underlying plaque morphology. TCFAs and fibroatheromas have the least luminal narrowing while lesions with acute plaque rupture, haemorrhage, or healed repair sites show the most stenosis. Over 74% of TCFAs have , 75% cross sectional area luminal narrowing (equivalent to , 50% diameter stenosis). Healed and acute plaque ruptures show the greatest luminal narrowing with 46% and 43%, respectively, containing , 75% cross sectional area narrowing. In contrast, only 26% of TCFAs show severe luminal narrowing (fig 3B). In a population where sudden cardiac death is the first manifestation of coronary disease, these morphologic findings strongly suggest that TCFAs are precursors to acute ruptures and healed plaque ruptures are often clinically silent.. TCFAs with ⩽ 50% diameter stenosis may be the ideal candidate lesions one should first attempt to identify and treat as a measure to reduce the incidence of myocardial infarction in high risk patients.

The present invention relates to a system of modeling a three dimensional target object which is represented by a plurality of cross-sectional images in order to provide a representative corresponding three dimensional model. The invention selects an initial model from a plurality of available initial models. This selection involves identifying an initial model based on physical similarity to the target object and then superimposing an initial model upon the target object, for each of the plurality of cross-sectional images. A determination is then made of an intersection contour of the initial model and a cross-sectional image of the target object and the determined intersection contour is refined in order to more closely delineate the target object. By sub-sampling points which represent the refined determined intersection contour, the invention obtains a sub-sampled contour dataset. The initial model is then adjusted towards the sub-samples contour to obtain a representative three dimensional

During a CT scan, a thin x-ray beam rotates around the patient. Detectors measure the x-rays and a computer creates a cross-sectional image or slice of that part of the body. A three-dimensional image can be created by combining the slices. The images interpreted by a radiologist (a doctor specialized in the reading of x-rays), who will report the results to your doctor. Your doctor will then provide you with this information ...
Individual projections create a cross-sectional image of the object as if it had been perfectly cut in half. The process, which functions much like when a doctor takes a CAT scan of a patients brain to look for abnormalities, renders a highly-detailed perspective that allows for unparalleled diagnostic analysis of the object. Even the most minor of structural flaws can be measured for repair or rendered large for study. Multiple X-ray images can be arrayed to create a single, three-dimensional model for a more in-depth consideration.. This technology allows for new possibilities in non-destructive testing:. ...

0059] The unit weight of a wireline cable, for example lbs/ft, may be reduced at lower portions by reducing the unit weight of the strength members at the lower portions of the cable. One skilled in the art will appreciate that the unit weight of the strength members is directly proportional to the density of the strength member material and the cross sectional area of the strength members at a location along the cable. By reducing the total cross sectional area of the strength members at a lower location with respect to an upper location, and assuming a substantially constant material density, the unit weight of the cable will be proportionately lighter at the lower location. The technique of tapering the strength members, described above, is one way to accomplish this reduction. FIG. 13A-C show other embodiments wherein the total cross sectional area of the strength members of the cable may be reduced at lower locations. FIG. 13A shows an upper end of cable 1300 having an inner layer 1302 and ...
During Rutherford cable production the wires are plastically deformed and their initially round shape is distorted. Using X-ray absorption tomography we have determined the 3D shape of an unreacted Nb3Sn 11 T dipole Rutherford cable, and of a reacted and impregnated Nb3Sn cable double stack. State-of-theart image processing was applied to correct for tomographic artefacts caused by the large cable aspect ratio, for the segmentation of the individual wires and subelement bundles inside the wires, and for the calculation of the wire cross sectional area and shape variations. The 11 T dipole cable cross section oscillates by 2% with a frequency of 1.24 mm (1/80 of the transposition pitch length of the 40 wire cable). A comparatively stronger cross sectional area variation is observed in the individual wires at the thin edge of the keystoned cable where the wire aspect ratio is largest ...
The rising popularity of lumbar interbody fusion over the past 2 decades has led to the concomitant evolution of a variety of interbody spacers. This proliferation of interbody spacers includes various combinations of different materials, architectures, and geometries with relatively little evidence basis for efficacy of any individual design. Initially, interbody spacers were designed at a fixed or static height. Expandable interbody spacers, whose height can be increased after insertion, allow for the smaller insertion height, theoretically minimizing some of the complications of PLIF or TLIF such as postoperative neurologic deficits. Additionally, by increasing disc space height, expandable spacers maximize the available interbody space for graft material. These theoretical benefits may be accentuated during MIS procedures due to the relatively limited decompression and disc space exposure. Potential concerns regarding expandable spacers include implant subsidence, mechanical failure, and ...

Suppose we have a PFR with the reaction B + 3C --, 2D, where B, C, and D are gaseous species. We are going to assume that the shear stress at the wall is very small so that the pressure gradient along the tube is very low, in which case the total pressure P is constant at the inlet pressure throughout the reactor. We are also going to assume that the heat of reaction is zero, so that the temperature throughout the reactor is constant at the inlet temperature T.

This paper presents the evaluation of a miniature liquid microflow sensor, directly integrated on a PCB. The sensor operation is based on the convective heat transfer principle. The heating and sensing elements are thin Pt resistors which are in direct electrical contact with the external copper tracks of the printed circuit board. Due to the low thermal conductivity of the substrate material, a high degree of thermal isolation is obtained which improves the operating characteristics of the device. The sensor is able to operate under both the hot-wire and the calorimetric principle. In order to fully exploit the temperature distribution in the flowing liquid, multiple sensing elements are positioned in various distances from the heater. A special housing was developed which allowed implementation of the sensor into tubes of various cross sectional areas. The sensor sensitivity and measurement range as a function of the sensing element distance were quantified. A minimum resolution of 3 μL/min and a
I would do a quick and dirty look at it by taking the load point as the fixed end of a cantilever beam and the force applied at the free end. That will give you the max bending moment and the resultant max bending stress. With only 72 N as your force, you will have plenty of saftey factor if you go with aluminum or steel with a decent cross sectional area. It shouldnt have to be very big. I would assume that dynamic forces will not be an issue here, i.e the speeds are low and the impact forces are negligible ...

Background Content: This case study examined the effects of a single Prolotherapy injection series on the left iliolumbar ligament. The ligament measurements were split between medial and lateral portions of the iliolumbar ligament and we hypothesized that growth would occur increasing the cross sectional area and thus provided added stability to the pelvis and lumbar spine.. Purpose: The purpose of our study was to answer two questions: 1) how do you know that the Prolotherapy injectant actually reaches the ligamentous structure you are attempting to heal; and 2) how long does it take for the ligament to recover?. Study Design: Single case study.. Methods: One subject, 32 year-old female with no history of lower back pain (LBP) participated in our study. Her job tasks as a physical therapist required her to twist turn and bend; putting pressure on her pelvis and ligamentous system. The primary author (A.A.) assessed her pelvic ligaments which lead to using a specified Prolotherapy solution for ...

DDD typically begins with small tears in the annulus of the disc (elastic outer ring of collagen fibers) and can lead to a decrease in the water content of the nucleus of the disc (soft gel center). The degenerative cascade of DDD can lead to disc bulging, development of bone spurs (called osteophytes), and loss of disc space height and/or alignment, which can cause nerve impingement. DDD can also lead to degenerative instability, the loss of the ability of the spine under physiologic loads to maintain its pattern of normal movement due to disc degeneration. ...

The invention provides encircling devices by which anatomical structures, such as blood vessels, fallopian tubes, ureters, vas deferens and outer nerve sheaths are anastomosed. Such an encircling device provides an opening that receives an end of a tubular anatomical structure having a prepared opening, and the tubular structure is anastomosed to a second anatomical structure having a prepared opening by tethering the two structures to the encircling device holding the structures under radial stress in apposition to each other to form a fluid-tight peripheral seal around their openings. Encircling devices are also used to join a tubular anatomical structure to a second anatomical structure having a cavity, e.g., a fallopian tube to a uterus or a uterer to the bladder. The tubular structure is received in the opening of the encircling device and tethered thereto to hold its end open, and then the encircling device is extended through a passageway in the second anatomical structure by means of a trocar,
Up to approximately 205 (dependent on drop-out rate) healthy elderly individuals (at least 65 years old) are recruited as subjects.. Upon inclusion, each individual will be randomized into one of the five groups stratified according to gender (M/F) and 30s chair stand (,16 OR ≥16). The five groups are: Heavy Resistance Training (N=30-35), Light Intensity Training (N=30-35), Protein Whey (N=40-50), Protein Collagen (N=40-50) and Carbohydrate (N=30-35). The individuals randomized into one of the supplementation groups (Protein Whey, Protein Collagen or Carbohydrate) will be blinded to the supplement content.. Assessments will be performed at Baseline (before intervention start), and after 6 and 12 months of intervention and again at 18 months (after 6 months of follow up).. The primary outcome is change in quadriceps muscle cross sectional area from Baseline to 12 months of intervention.. The primary hypothesis is that by applying the intension-to-treat analysis, the Light Intensity Training ...

Computed tomography (CT or CAT scan) is a noninvasive diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than standard x-rays.. In standard x-rays, a beam of energy is aimed at the body part being studied. A plate behind the body part captures the variations of the energy beam after it passes through skin, bone, muscle, and other tissue. While much information can be obtained from a standard x-ray, a lot of detail about internal organs and other structures is not available.. In computed tomography, the x-ray beam moves in a circle around the body. This allows many different views of the same organ or structure. The x-ray information is sent to a computer that interprets the x-ray data and displays it in a two-dimensional (2D) ...
The CT (Computed Tomography) scan or the CAT (Computer-Aided Tomography) scan is a diagnostic procedure that takes a detailed cross-sectional x-ray picture of a slice of the body.. To get a CT scan, the patient lies very still on a table, which is slowly moved horizontally while the x-ray machine rotates around the patient and takes pictures from many angles. A computer then combines the pictures into a very detailed cross-sectional image. The length of the procedure depends on the areas to be x-rayed. For the chest area, the procedure takes about 20 seconds.. CT scans can show the shape, size and the exact location of organs and tissues in any slice of the body more clearly than other diagnostic tools. This technique can help find enlarged lymph nodes, which might contain cancer that has spread from the lung. CT scans are more sensitive than routine chest x-rays in finding early lung cancers. CT scans are also used in detecting masses in the liver, adrenal glands, brain and other internal ...
Magnetic resonance imaging (MRI) uses a magnetic field and radio waves to create cross-sectional images of your head and body. Your doctor uses these detailed, clear images to identify and diagnose many conditions. It is particularly helpful in providing details about soft tissues, including the spinal cord, nerves and the discs between the bones of the spine.
Computerized Tomography (CT Scan or CT) combines a series of x-ray views taken from many different angles and computer processing to create cross-sectional images of the bones and soft tissues inside your body. A CT scanner is a tube (shaped like a donut) surrounded by a giant magnet. The patient is placed on a moveable bed that is inserted into the magnet. Occasionally, patients require injections of liquid intravenously to enhance the images of the study. CT Scanning time depends on the exact area of the body being studied, but ranges from 5 to 30 minutes.. ...
