The Right

The reproductive and associated organs of both male and female T. georgianus are briefly described. In females, only the right ovary is functional and pregnancies occur only in the right horn. They are monovular and the corpus luteum occupies most of the ovary and is deeply embedded in its stroma. Females are monotocous and the gestation period is probably about 4 months, young being born from October to February. They are monestrous and there is an autumn and early winter dioestrousanoestrous period. Spermatozoa are not stored in the reproductive tract of females and copulation appears to coincide with the oestrous condition. In males, spermatogenesis proceeds throughout the year and spermatozoa are present in the epididymis and vas deferens in all months that males were collected (no records for December). Spermatozoa are also found in the ampulla of Henle and vesicula seminalis in most months of the year. The position of the testes varies with season: in summer they descend to the scrota1 sacs; in autumn, winter, and spring they are more abdominal.

one of 353 port jackson sharks, heterodontus portusjacksoni, caught off the southern coast of western australia, was a hermaphrodite. the female reproductive tract consisted of a large (functional) right ovary with three large yolked ova, a small non-functional left ovary and two well-developed uteri and oviducal glands. the male tract comprised two conspicuous but undeveloped testes, two vas deferens and two calcified claspers with grooves. this individual represents the first published example of hermaphroditism in the order heterodontiformes and is a rare example of an elasmobranch with a complete suite of both male and female reproductive structures.

ABSTRACTThe fertility, mortality, and migration patterns of Heterakis gallinarum were studied in chickens with concomitant Parahistomonas wenrichi infections. H. gallinarum females were found to produce approximately 936 ova per day, when 50 days of age, and a total of 34,000 to 86,000 ova in a lifetime. There was no evidence of differential mortality between the sexes, nor of a preference for either the left or the right caecal organ of chickens. Both male and female worms are capable of migrating between caeca, and are especially prone to do so when in the absence of individuals of the opposite sex.

SummaryActeon tornatilis is an opisthobranch mollusc which burrows in sand, using foot, labial and cephalic tentacles in the process. The last also help to exclude sand from the mantle cavity, which is extended into a caecum coiling alongside the visceral hump, presumably used for respiration but also for excretion. The main pallial water current is an exhalant one on the right.The mantle skirt carries, on the left, numerous repugnatorial glands with toxic secretions.Labial glands lie at the mouth and the buccal cavity contains jaws and a reduced buccal mass and radula. Into it open salivary glands the structure of which is like that of the pyramidellids. The oesophagus shows traces neither of glands nor of torsion whereas the stomach, though simplified, has resemblances to that of a prosobranch.The reproductive system is shown to be different from previous descriptions. Male and female ducts are separate from the lower end of the little hermaphrodite duct. The former passes to a prostate from which a vas deferens leads to a large uninvaginable penis; the latter has associated albumen and mucous glands and there is a receptaculum seminis to the duct of which a ventral channel leads from the female aperture in the mantle cavity.Discussion of these aspects of the animal's structure confirms its position as the most primitive of the opisthobranchs.

Numerous variations of vessels arising from the aortic arch have been reported. One of the common anatomical variations in the right subclavian artery originating as the last branch of the aortic arch. This report demonstrates two cases of the retroesophageal right subclavian artery in an adult male and female. To highlight the significance of a retro esophageal right subclavian artery, especially its clinical and surgical implications. Multi-slice computed tomography (CT) of a case of an anomalous vessel. This report shows a retro esophageal subclavian artery originating as the last branch from the postero-lateral aspect of the thoracic aorta at the vertebral level T4. No abnormality was seen neither in the heart nor in no other vascular system in this region. Radiologists mainly encounter a retroesophageal right subclavian artery incidentally and are usually described as asymptomatic, but several clinical conditions have been associated with this kind of occurrence.

The Right

No one wants to be treated like an object, regarded as an item of property, or put up for sale. Yet many people frame personal autonomy in terms of self-ownership, representing themselves as property owners with the right to do as they wish with their bodies. Others do not use the language of property, but are similarly insistent on the rights of free individuals to decide for themselves whether to engage in commercial transactions for sex, reproduction, or organ sales. Drawing on analyses of rape, surrogacy, and markets in human organs, this book challenges notions of freedom based on ownership of our bodies and argues against the normalization of markets in bodily services and parts. The book explores the risks associated with metaphors of property and the reasons why the commodification of the body remains problematic. The book asks what is wrong with thinking of oneself as the owner of one's body? What is wrong with making our bodies available for rent or sale? What, if anything, is the difference between markets in sex, reproduction, or human body parts, and the other markets we commonly applaud? The book contends that body markets occupy the outer edges of a continuum that is, in some way, a feature of all labor markets. But it also emphasizes that we all have bodies, and considers the implications of this otherwise banal fact for equality. Bodies remind us of shared vulnerability, alerting us to the common experience of living as embodied beings in the same world. Examining the complex issue of body exceptionalism, the book demonstrates that treating the body as property makes human equality harder to comprehend.

Ameloblastic fibroma is an uncommon mixed neoplasm of odontogenic origin with a relative frequency between 1.5 – 4.5%. It can occur either in the mandible or maxilla, but predominantly seen in the posterior region of the mandible. It occurs in the first two decades of life. Most of the times it is associated with tooth enclosure, causing a delay in eruption or altering the dental eruption sequence. The common clinical manifestation is a slow growing painless swelling and is detected during routine radiographic examination. There is controversy in the mode of treatment, whether conservative or aggressive. Here we reported a 38 year old male patient referred for evaluation of painless swelling on the right posterior region of the mandible associated with clinically missing 3rd molar. The lesion was completely enucleated under general anesthesia along with the extraction of impacted molar.

Speech Clause

This book examines the relational dynamics between the U.S. Constitution’s Free Speech Clause and other constitutional rights. The free speech guarantee has intersected with a variety of other constitutional rights. Those intersections have significantly influenced the recognition, scope, and meaning of rights ranging from freedom of the press to the Second Amendment right to bear arms. They have also influenced interpretation of the Free Speech Clause itself. Free speech principles and doctrines have facilitated the recognition and effective exercise of constitutional rights, including equal protection, the right to abortion, and the free exercise of religion. They have also provided mediating principles for constructive debates about constitutional rights. At the same time, in its interactions with other constitutional rights, the Free Speech Clause has also been a complicating force. It has dominated rights discourse and subordinated or supplanted free press, assembly, petition, and free exercise rights. Currently, courts and commentators are fashioning the Second Amendment right to keep and bear arms in the image of the Free Speech Clause. Borrowing the Free Speech Clause for this purpose may turn out to be detrimental for both rights. The book examines the common and distinctive dynamics that have brought free speech and other constitutional rights together. It assesses the products and consequences of these intersections, and draws important lessons from them about constitutional rights and constitutional liberty. Ultimately, the book defends a pluralistic conception of constitutional rights that seeks to leverage the power of the Free Speech Clause but also to tame its propensity to subordinate, supplant, and eclipse other constitutional rights.

School Movement

By the 1840s, convent narratives gained more middle-class, respectable readers, moving away from descriptions of sex and sadism and focusing instead on convent schools and the education of young women. Popular works such as Protestant Girl in a French Nunnery described "tricks" used by nuns to convert female pupils and lure them into convents. Such literature warned that as neither wives nor mothers, nuns could not train the right kind of women for America. The focus on convent schools converged with the common or public school movement. At the same time, teaching became an acceptable occupation for women, prompting more women to seek opportunities for higher education. This chapter compares the approach to education among nuns and other female teachers alongside the caricatures of convent schools in anti-Catholic print culture. I seek to answer why convent schools faced such heightened animosity even as teaching became feminized.

Safe Working

ABSTRACTMany oppose the mandatum as a threat to the academic freedom of Catholic scholars and the autonomy and credibility of Catholic universities. But the imposition of this juridical bond on working theologians is also in tension with Catholic Social Teaching on the rights and dignity of labor. Work is the labor necessary to earn our daily bread. But it is also the vocation by which we realize ourselves as persons and the profession through which we contribute to the common good. Thus, along with the right to a just wage and safe working conditions, Catholic Social Teaching defends workers' rights to a full partnership in the enterprise, and calls upon the church to be a model of participation and cooperation. The imposition of the mandatum fails to live up to this standard and threatens the jobs and vocations of theologians while undermining this profession's contribution to the church.
