The axillary vein is a large venous structure that represents the continuation of the basilic vein. It starts at the lower border of the teres major tendon and... 

Total flexion of the shoulder joint can also be divided into three phases. In the first phase (0 to 60 degrees), the muscles used are the anterior fibers of the deltoid, the coracobrachialis, and the clavicular fibers of the pectoralis major. Motion is limited by the tension of the coracohu-meral ligament and by the resistance offered by the teres minor, teres major, and infraspinatus muscles. 

From the anatomic point of view, the muscles of the shoulder may be subdivided into two main groups intrinsic musdes (subscapularis, supraspinatus, infraspinatus, teres minor, teres major and deltoid), which originate and insert on the skeleton of the upper limb, and extrinsic muscles, which join the upper limb with either the spine (trapezius, latis-simus dorsi, levator scapulae and rhomboid) or the thoracic wall (serratus anterior, pectoralis minor... 

If needle electrode is inserted too cephalad, it will be in the supraspinatus if inserted too caudally, it will be in the teres major if inserted too superficially, it will be in the trapezius. If inserted too medially, it will be in the Infraspinatus. 

Latissimus dorsi if inserted too cephalad it will be in the teres major. 

A significant fraction—about 15% for aluminum, 30% for copper, and 50% for gold—of the beam electron trajectories intersect the surface and escape as backscat-tered electrons (BSEs), as shown in Figure 2a. The majority of BSEs escape with more than half of their incident energy. Clearly, if these electrons had remained in... 

Fig. 17.9 The H assignment of the unlabeled pheromone 2-see-butyl-4,5-dihydrothiazole, bound to [U-13C, 15N]-labeled mouse major urinary protein I, was accomplished by comparing the 2D TOCSY spectrum of free ligand (A) to the 13C-fil-tered TOCSY spectrum of the complex (B).

The pyridine ring system may carry snbstituents, jnst as we have seen with benzene rings. We have enconn-tered a nnmber of snch derivatives in the previons section. Hydroxy or amino heterocycles, however, may sometimes exist in tautomeric forms. We have met the concept of tantomerism primarily with carbonyl componnds, and have seen the isomerization of keto and enol tantomers (see Section 10.1). In certain cases, e.g. 1,3-dicarbonyl componnds, the enol form is a major component of the eqnilibrinm mixtnre. In the example shown, liquid acetylacetone contains about 76% of the enol tautomer.

Elastin is an elastic insoluble protein in connective tissue, with cross-linked tropoelastin as a major component. It is responsible for the contraction of skin, lung, and vascular tissues in our body [42]. The insolubility and enhanced immune response [43] of native elastin limits its biomedical application and demands new materials for tissues. The ability of elastin to maintain minimum platelet interaction makes it a suitable material for making biological coatings for synthetic vascular grafts [44,45]. Currently used synthetic vascular biomaterials like poly(ethylene tere-phthalate) (Dacron) and poly(tetrafluoroethylene) show... 

Table I lists the varions types of pores systems enconn-tered in petrolenm reservoirs. There are two main types of pores primary (or syndepositional) and secondary (or postdepositional). Primary pores are those thatformwhen a sediment is deposited. They may be either inteigran-nlar, occnrring between grains, or intragranirlar, occurring within grains. The former is common in terrigenous sediments and is therefore the major type of pore found in sandstone reservoirs (Fig. 3). Intraparticle pores occur within shells in skeletal hme sands. Dirring burial, however, these pores are often destroyed by compaction or by cementation.

The second most important class of commercial polycarbonate blends is derived by blending with commercial thermoplastic polyesters such as polybutylene tere-phthalate (PBT) and polyethylene terephthalate (PET). Both PBT and PET are crystallizable polymers and hence offer the expected chemical resistance advantages of the crystalline polymers in blends with polycarbonate. Among the thermoplastic polyester/polycarbonate blends, the PBT/PC blend has the major commercial volume, followed by the PET/PC blend. A copolymer of 1,4-cyclohexanedimethanol, ethylene glycol, and terephthalic acid (PCTG) forms a miscible blend with polycarbonate. PCTG/PC blend was earlier offered by Eastman (Ektar ) for specialty applications, but it is no longer commercial. 

Combined morphine/naltrexone capsules are to be swallowed whole or the contents of the capsules sprinkled on apple sauce and the pellets in the capsules are not to be crushed, dissolved, or chewed. A pK study of combined morphine/naltrexone crushed vs. whole was done to compare the plasma concentrations and relative bioavailability of morphine, naltrexone, and the major naltrexone metabolite (6-P-naltrexol). Plasma morphine levels from crushed morphine/naltrexone capsules showed no extended-release properties. While concurrent administration of high-fat food decreased the rate and extent of morphine absorption from combined morphine/naltrexone, the total bioavailability or sequestration of naltrexone was not affected. An alcohol effects study examined the bioavailability of combined morphine/naltrexone when dosed under fasting conditions with 4%, 20% and 40% alcohol compared to water. The rate and extent of bioavailability and total exposure to morphine (AUC, C ) were not affected when the drug was adminis-tered concomitantly with either 4% or 20% alcohol, when compared to administration with water. When combined morphine/naltrexone was administered with 40% alcohol (240 mL over 15 minutes), the rate and extent of bioavailability (C ) doubled and the t was 5 hours earlier, when compared to administra-tion with water. The total systemic exposure to morphine (AUC) was not affected [9]. 

The capsule of the glenohumeral joint is loose and pleated. The ligaments, which are merely thickenings in the capsule, provide little support. The major support of the humerus into the fossa is provided by the rotator cuff muscles, which hold the head into the fossa. These muscles include the supraspinatus, infraspinatus, teres minor, and subscapularis. Abduction-adduction and axial and horizontal rotations are coupled in that angular motions are accompanied by translatory slides. The caudal slide of the humeral head with abduction confers increased freedom of motion on the supraspinatus tendon beneath the coracoacromial ligament. 

Aromatic polyketones were first produced in the 1960s and 1970s by W.H. Bonner at DuPont. Low molecular weight PEKK by Friedel-Crafts acylation diphenyl ether using isophthaloyl chloride or tere-phthaloyl chloride were reported [55]. The insolubility of these polymers presented a major synthetic problem as it limited the molecular weight that could be obtained before the growing polymer chains crystallized out from the solution. 

The major nerves and vessels of the forearm are located within or traverse the volar compartment (Fig. 9.3). The median nerve enters the volar compartment passing between the superficial and deep heads of the pronator teres muscle. It then crosses the ulnar artery and proceeds toward depth to pass...
