Examination of the genitalia of male bobcats collected in Arkansas revealed the common occurrence of bacula. The preformed architecture of dense connective tissue and cartilage was evident in juveniles (<1 year). Observed morphological variation in adults was partially ascribed to ontogeny. Maximum dimensions observed were 7.6 mm (length) and 3.1 mm (width). The distal portion of the baculum is a narrow shaft, while the proximal region is expanded and bifurcated ventrally. A vertical septum separates two vacuities in the base of the baculum. These vacuities house the primarily adipose ends of the corpora cavernosa. Morphology of the baculum of the bobcat is similar to that of the European lynx, and, while different from other felids, it indicates validity of the genus Lynx.

Cryptosporidiumfelis is an important cause of feline and human cryptosporidiosis. However, the transmission of this pathogen between humans and cats remains controversial, partially due to a lack of genetic characterization of isolates from cats. The present study was conducted to examine the genetic diversity of C. felis in cats in China and to assess their potential zoonotic transmission. A newly developed subtyping tool based on a sequence analysis of the 60-kDa glycoprotein (gp60) gene was employed to identify the subtypes of 30 cat-derived C. felis isolates from Guangdong and Shanghai. Altogether, 20 C. felis isolates were successfully subtyped. The results of the sequence alignment showed a high genetic diversity, with 13 novel subtypes and 2 known subtypes of the XIXa subtype family being identified. The known subtypes were previously detected in humans, while some of the subtypes formed well-supported subclusters with human-derived subtypes from other countries in a phylogenetic analysis of the gp60 sequences. The results of this study confirmed the high genetic diversity of the XIXa subtype family of C. felis. The common occurrence of this subtype family in both humans and cats suggests that there could be cross-species transmission of C. felis.

1 To determine if the risk of aspiration is increased in 'Dettol' (4.8% chloroxylenol, pine oil and isopropyl alco hol) poisoning and the factors that may be responsible, a study was made of 89 patients and 89 matched control subjects with other forms of poisoning admitted to the Prince of Wales Hospital, Hong Kong. 2 Aspiration was more common in patients with Dettol poisoning (8% vs 3%, P = 0.16). There were more control subjects with drowsiness at presentation (54% vs 24%, P < 0.0001), but the use of gastric lavage (88% vs 64%, P < 0.001) and the occurrence of vomiting (62% vs 17%, P < 0.0001) were more common in patients with Dettol poisoning. 3 Our findings suggest that Dettol poisoning may be asso ciated with an increased risk of aspiration. This increase in risk may be related to the use of gastric lavage and the common occurrence of vomiting in patients with Dettol poisoning.

Snail Helix Aspersa

The cation of methyl green carriea two poaitive charges, that of malachite green only one; but the two dyes behave towards tissue-constituents in almost exactly the same way. These dyes are not specific for chromatin. They colour certain objects that are devoid of DNA, even when they are used in very dilute solution. The granules of cells called Körnchenzellen in the connective tissue of the common snail, Helix aspersa, are strongly coloured by both dyes from very dilute solutions, and thus provide a striking instance of the unspecificity of these dyes. Malachite green, which is stable and free from contamination by metachromstic impurities, can advantageously replace the methyl green commonly used in mixtures with pyronine. It is suggested that pyronine may have a greater capacity for penetrating into close-textured objects, such ss nucleoli and ribosomes, than methyl and malachite greens.

Rupture Mechanism

A mathematical model of the A2 pulley system will enable us to have a better understanding of the mechanics of the pulley-tendon system and provide us with insights of the pulley rupture mechanism. The A2 pulley was modeled based on parallel pulley fibers attached to a phalanx with a tendon passing them. Mechanical properties of the pulleys such as stiffness, strength and friction were included in the model. A convergence test was done to ensure the accuracy of the test. The model managed to show high loads on flexed finger may lead to pulley ruptures. Further studies on the rupture mechanism showed that pulley ruptures are self-propagating when a constant force is applied and the rate of rupture increases, as fewer intact fibers are present to support the load. The initial rate of propagation is much slower and this accelerates as more fibers are ruptured. This explains the common occurrence of partial pulley ruptures.

The skeleton provides the framework and anchor points against which muscles, attached via tendons, can exert force. Three types of cells are involved in making bone: osteoblasts, osteoclasts, and cartilage. The human muscle system is made up of three types of muscle tissue: skeletal, cardiac, and smooth. The neonate period of life is the first 4 weeks after the birth of an infant. This chapter presents 11 genetic disorders that affect muscles, connective tissue, and newborns. These include achondroplasia, Charcot-Marie tooth syndrome, Duchenne Muscular Dystrophy, Ellis-Van Creveld syndrome, amyotrophic lateral sclerosis, Marfan syndrome, fibrodysplasia ossificans progressive, myotonic dystrophy, Angelman syndrome, Prader-Willi syndrome, fragile-X syndrome, and Waardenburg syndrome.

Many immune-mediated diseases and infections affect the central and peripheral nervous systems. The common feature that characterizes both immune-mediated diseases and infections is a subacute temporal profile. Immune-mediated disease can affect only the nervous system or involve the nervous system as part of a systemic illness, as in vasculitis and connective tissue disease. Multiple sclerosis (MS), the most common disabling neurologic illness of young people, is the prototypical immune-mediated disease of the central nervous system (CNS).

The Way

In the UK alone there are approximately 175,000 acute burn injuries /year. There is a great variation in the way these injuries are managed. Advances in our understanding of the pathophysiology and natural history of burn injuries have highlighted the importance of early intervention in minimizing later functional and cosmetic morbidity. Differences in beliefs and ethnic background have a large impact on the way that burns are initially dealt with, as we know that only a minority of patients presenting with burns are optimally managed pre-hospital. Lack of education and conflicting information about burns first aid is believed to be a major factor in the common occurrence of burnt patients presenting with a variety of domestic remedies being applied to their burns as first aid. Judicious application of simple burns first aid is the first step for soft tissue preservation, improvement of outcomes and a decrease in the need for operative management.

SummaryGrowth twins, parallel growths, and necked crystals are described from zircon populations from granitic gneisses from the Precambrian of SW. Greenland. From observations of the distribution of internal growth zones it is concluded that whereas twinning takes place early in the growth history of elbow twins it can occur at any time during crystallization of the zircon. Parallel growth is attributed to a process of synneusis or attachment of zircons that have initially undergone separate growth histories. This implies that viscosity conditions of the rocks were low enough to permit the movement and collision of growing zircon crystals. The common occurrence of zircons with central constrictions, sometimes superimposed on transverse fractures, in zircon suites from the granitic gneisses is explained in terms of late-stage chemical corrosion accompanied by brittle fracturing.

The inflorescence and floral ontogeny of the oleaceous tropical bush, Jasminum fruticans L. were studied using epi-illumination light microscopy and compared with other Oleaceae. The flowers are arranged in a thyrsoid inflorescence with a determinate pattern of development. Deviations from the common pathway of floral ontogeny in Oleaceae observed in J. fruticans are characterised by pentamery in calyx and corolla, diagonal position of sepals, some deviation from acropetal and simultaneous initiation of floral organs. Sepals are helically initiated, beginning with the abaxial sepal. Formation of petal lobes from the ring meristem also is not simultaneous with the initiation of three petals before the others. Concurrently with the formation of corolla ring, two stamens are initiated sequentially. Two median carpels are the last organs to be initiated. Unusual features of organ enlargement include the quincuncial-imbricate aestivation of the corolla and formation of trichomes on the distal portion of petals and stamens.
