Active movement

Joint examination may reveal local tenderness, bony proliferation, soft tissue swelling, crepitus, muscle atrophy, limited motion with passive/active movement, and effusion. 

The neuronal ceroid lipofuscinoses (CLN), also referred to as Batten s disease, are a group of disorders characterized by the accumulation of autofluorescent lipopigments. Clinical hallmarks include blindness, seizures, cognitive and motor decline and early death. Age of onset varies from infancy to adulthood. Eight genetic forms have been identified [4]. Two involve lysosomal acid hydrolases. CLN1 codes for palmitoyl protein thioesterase 1. Clinically it presents most often in infancy and leads to loss of active movement and visual contact by 3 years of age. It is most common in Finland, where its incidence is 1 20,000. CLN2 codes for a lysosomal pepstatin-insensitive acid protease. 

From the mid esophagus to the anus, smooth muscle surrounds the alimentary canal and is responsible for active movement and segmentation of intestinal contents. This smooth muscle, which lies in the muscularis propria, consists of a circular and a longitudinal layer of muscle. 

Movement of polar compounds and ions across biological membranes requires protein transporters. Some transporters simply facilitate passive diffusion across the membrane from the side with higher concentration to the side with lower. Others bring about active movement of solutes against an electrochemical gradient such transport must be coupled to a source of metabolic energy.

The quantitative variations in space perception that occur in the ordinary d-SoC may occur in greatly increased form in d-ASCs. Distances walked, for example, may seem much shorter or much longer than ordinarily. Nor is active movement through space necessary for changes in distance to occur as you sit and look something, it may seem to recede into the distance or to come closer. Or it may seem to grow larger or smaller. 

Triazine herbicide soil activity, movement, and residues depend primarily on content of organic matter, and to a lesser extent, clay colloids (Nearpass 1965 Day et al, 1968 Weber et al, 1969). Soils that are low in organic matter or clay usually require lower herbicide rates, but result in more potential phytotoxicity (Lange et al, 1969a). Simazine (4.0kg/ ha) or diuron (5.0kg/ha) gave season-long weed control in soils of the Northwest (Hogue and Neilsen, 1987). 

Figure 29.5. Schematic illustration of passive and active movement of electrolytes and water following glomerular filtration. Concentrations of tubular urine and peritubular fluid are given in milliosmoles per liter. Horizontal lines represent areas of increasing interstitial osmolarity. Tubule segments edged with thick black lines are either impermeable to water (loop of Henle) or display antidiuretic hormone-dependent water permeability (collecting duct).

Movement of the sulfate moiety by one position towards the N-terminus ([TyrCSOgH), Phe , Nle ]LSK) led to a very significant 38% retention of parent peptide ([Nle ]LSK) activity. Movement of the sulfate group by two to five positions towards the N-terminus (represented by analogs [Tyr(S03H), Phe ,...

A 66-year-old kidney transplant recipient developed a gangrenous lesion on the left foot infected with S. aureus and Escherichia coli. He was given ciprofloxacin and chndamycin for 6 weeks and then fusidic acid 1500 mg/day for 2 weeks. He became Ul, with myalgia and no active movement of his legs, and rhabdomyolysis was established by laboratory tests. He had also taken atorvastatin 10 mg/day and he slowly recovered after withdrawal of both atorvastatin and fusidic acid. 

In this subsection we examine the mechanism of the very fast diffusion. In the bulk medium the vacancies and interstitial site play a primary role in accelerating the diffusion. However, these diffusion mechanisms are not relevant in microclusters. It is well known that the vacancies created inside the cluster are immediately pushed to the surface. Indeed in our simulation the creation of vacancies inside the cluster is a very rare event even at the temperature close to the melting temperature. Moreover, we cannot find any evidence that the interstitial deformation takes place inside the cluster, and therefore neither of them is responsible for the rapid diffusion into the cluster. The key feature of the cluster that distinguishes the cluster from the bulk medium is that it is surrounded by the surface beyond which no atoms exist. In other words, the outside of the cluster is occupied by vacancies. As a result, the atoms on the surface move very actively along the surface. Such an active movement along the surface will be responsible for the rapid diffusion in the radial direction of the cluster. We focus our attention to the details of the active diffusive motion along the surface of the cluster, and we present a direct evidence that the surface activity controls the radial diffusion. A direct measure of the surface motion is the diffusion rate of the surface atoms... 

Movements of water are due mainly to osmosis and filtration. In osmosis, water moves to the area of highest solute concentration. Thus, active movement of salts into an area creates a concentration gradient down which water flows passively. In filtration, hydrostatie pressure in arterial blood moves water and nonprotein solutes through specialized membranes to produce an almost protein-free filtrate This process occurs in formation of the renal glomerular filtrate. Filtration also accounts for movement of water from the vascular space into the interstitial compartment, which is opposed by the osmotic (oncotic) pressure of plasma proteins. 

However, new support for the somatic electromotility model of cochlear amplification has been provided by Jia and He (2005), who demonstrated, using a coil preparation of the gerbil cochlea, that active hair bundle movement depends on the developmental onset of somatic electromotility. At postnatal day 4 (P4), when hair bundle MET channels are functional but the OHCs are not yet electromotile, no hair bundle motility could be detected from the apical turn of the coil in response to a sinusoidal voltage command (Jia and He, 2005). The hair bundle movement appeared when somatic electromotility developed. This observation is supported by findings from studies of the cochlea of prestin knockout mice, in which active movement of the hair bundle is not detected despite the presence of functional MET channels (Jia and He, 2005). In addition, the amphtude of the motility-associated hair bundle movement is 20 dB greater than that of the transduction-charmel-based hair bundle motion. They propose that somatic motility in conjunction with bundle motion is responsible for the cochlear amplifier (Jia and He, 2005).

A diffusive/passive sampler is a device which is capable of taking samples of gas or vapour pollutants from the atmosphere at a rate controlled by a physical process such as diffusion through a static air layer or permeation through a membrane, but which does not involve the active movement of air through the sampler (Brown, 1993 Moore, 1987). Compared with methods requiring pumps for active air movement, diffusive samplers are more convenient and have lower associated costs.
