Capsule 8-ribbed

Features Stem purplish-brown, cylindrical below, becoming quadrangular higher up, pithy, nearly quarter-inch thick. Leaves opposite, three to seven longitudinal ribs, entire. Fruit (capsule) one-celled, two valved. Extremely bitter taste. 

Acetobacter xylinum produces two forms of cellulose (1) cellulose I, the rib-bon-like polymer, and (2) cellulose II, the thermodynamically more stable amorphous polymer [9]. They can be divided according to their morphological localization as intracellular polysaccharides located inside, or as part of the cytoplasmic membrane cell wall polysaccharides forming a structural part of the cell wall and extracellular polysaccharides located outside the cell wall. Extracellular polysaccharides occur in two forms loose slime, which is non-adherent to the cell and imparts a sticky consistency to bacterial growth on a solid medium or an increased viscosity in a liquid medium and microcapsules or capsules, which adhere to the ceU wall. 

Description Herbaceous perennial. Leaves in basal rosettes, narrow-elliptic to lanceolate-elliptic, 7.5-35 cm long, 0.5-3.5 cm wide, with 3-5 parallel veins, apex acute, narrow petiolate. Inflorescence a dense, erect, cylindrical spike, 1.5-8 cm tall peduncles 15-60 cm tall, with 5 ribs bracts ovate, acute. Corolla 4-lobed. Fruit a 2-seeded, circumscissile capsule. Seeds elongate-oval. 

As these patients have diminished renal function due to the obstruction, intravenous contrast medium with delayed fluoroscopic imaging is no longer used unless contrast medium has already been administered as part of a CT study and there is adequate opacification of the calices. Ultrasound (US) is used to guide the needle towards a posterior (usually lower pole) calix. An initial US will give an appreciation of the position of the kidney relative to certain surface landmarks such as the twelfth rib. The skin is then cleansed and draped and local anesthetic administered, both to the skin and deeper to the surface of the renal capsule. 

The heads of the second through twelfth ribs articulate with the bodies of the corresponding vertebrae and the one above, as well as with the corresponding intervertebral disk. However, the first rib articulates only with the superior aspect ofTl. The costovertebral articulation is a synovial joint, with a joint capsule that is strengthened by the radiate ligament (see Costovertebral Ligaments). 

The costotransverse articulation is a joint representing the articulation of the tubercle of a rib with the transverse process of the corresponding vertebra. Thejoint is surrounded by a weak capsule that is greatly strengthened by the costotransverse ligaments. 

The costovertebral Joint is the articulation of the rib head with the bodies of one or two vertebrae. For a typical rib, the costovertebral joint includes the bodies of the vertebra at the same level and the vertebra immediately above, the annulus fibrosis of the intervening disk, and the costal facets. It is a synovial joint with a single capsule. The facets of the costovertebral joint are... 

The costotransverse articulation is likewise a simple synovial joint surrounded by a capsule. Three ligaments—the superior, posterior, and interosseous costotransverse ligaments—connect the transverse process to the neck of the tubercle. The superior costotransverse iigament also connects the transverse process to the neck of the next lower rib. 

The second functional joint is the scapulothoracic joint. This is formed by the scapula and the posterior thorax (ribs). Because muscle and fascia lie between the articulating surfaces, it is not a true joint with approximated articular surfaces and is also lacking a capsule. 

The spleen is the largest of all lymphatic tissues and rests against the lower ribs (nine through eleven), the diaphragm, the stomach, and the left kidney in the left hypochondral region. A parenchyma of red and white pulp is surrounded by a capsule of fibrous connective tissue that contains efferent lymphatics, blood vessels, nerves, and some smooth muscle. The red pulp is a cordal and sinusoidal system concerned primarily with the production of blood products. The while pulp, which is lymphoid tissue, produces ihymus-dependent T lymphocytes and B lymphocytes and plasma cells. The latter components produce the humeral antibody component of the immune system, and the T-lymphocytes are involved in the cell-mediated arm of the system. The vasculature consists of the splenic artery, the largest branch from the celiac trunk, and the splenic vein, which unites with the mesenteric vein to form the portal vein. 

A hexaamide covalent capsule 148 with an extended macrobicyclic framework has been described in [111] as a first polynucleating amide caging ligand with two of three pyridine-containing ribbed fragments having the same orientation and the third one looking at the... 

At the same time, the coordination capsule 581 efficiently binds air-sensitive white phosphorus by Scheme 4.73, thus giving an air-stable 1 1 cage complex with an encapsulated P4 guest molecule. This complex has been characterized in [73] using H and NMR spectra and by X-ray diffraction data. The P4 molecule within the cavity of a coordination capsule 581 is stabihzed by van der Waals interactions with the hydrophobic phenyl-ene ribbed fragments of its cage framework and is air stable for a long time, even in aqueous solu-... 

A Pd2L3 coordination capsule 766 has been prepared in [187] in a quantitative yield by self-assembly of palladium(n) ions with a bananashaped hgand syntone 389 by Scheme 4.183. This rigid capsule is formed by two cross-linking palladium(n) ions with square-planar coordination polyhedra at the distance of 17 A and four ribbed...
