Despite its unpopularity, the rectal route of paediatric drug administration remains of interest especially in pre-school children as it can overcome some drug delivery challenges with oral and parenteral routes. Few studies have been conducted on the use and acceptability of traditional rectal dosage forms (i.e., suppositories, enemas and gels) in different parts of the world. It showed that barrier to adoption could be linked with poor knowledge, little information and understanding of this administration modality. Reformulation for the rectal delivery of drugs intended for oral and/or parenteral administration that do not reach their full potential, was explored by a study at University College London. The top 3 candidates were Azithromycin, Amodiaquine and Raltegravir. Little rectal delivery innovation has occurred but topics such as acceptability and use of rectal drug delivery; types of rectal dosage forms and reformulation considerations are discussed presently in order to raise awareness around the need to modernise rectal dosage forms this to achieve the full potential for successful reformulation.

During recent decades, researchers all around the world have focused on the characteristic pros and cons of the different drug delivery systems for cornea tissue change for sense organs. The delivery of various drugs for cornea tissue is one of the most attractive and challenging activities for researchers in biomaterials, pharmacology, and ophthalmology. This method is so important for cornea wound healing because of the controllable release rate and enhancement in drug bioavailability. It should be noted that the delivery of various kinds of drugs into the different parts of the eye, especially the cornea, is so difficult because of the unique anatomy and various barriers in the eye. Nanoparticles are investigated to improve drug delivery systems for corneal disease. Biodegradable nanocarriers for repeated corneal drug delivery is one of the most attractive and challenging methods for corneal drug delivery because they have shown acceptable ability for this purpose. On the other hand, by using these kinds of nanoparticles, a drug could reside in various part of the cornea for longer. In this review, we summarized all approaches for corneal drug delivery with emphasis on the biodegradable nanoparticles, such as liposomes, dendrimers, polymeric nanoparticles, niosomes, microemulsions, nanosuspensions, and hydrogels. Moreover, we discuss the anatomy of the cornea at first and gene therapy at the end.

Conventional ophthalmic dosage forms, although being simple to apply and presenting great patients' compliance, display poorer drug bioavailability and retention time on the eye surface. To cope with these problems, one must formulate novel drug delivery systems, such as nanosystems, for ocular drug delivery. Different formulation methods of nanoparticles have been developed, but some of them, such as the supercritical fluid method, have not reached their full potential in ocular drug delivery. This article aims to present the possibilities of the supercritical fluid method when preparing nanosystems for ocular drug delivery. This method could be used more frequently and efficiently because it is environmentally friendly and produces nanoparticles of the desired physicochemical properties, which is especially important in ocular drug delivery considering its peculiarities. Modifications of the supercritical fluid method can be used when a drug has some specific properties, which is an additional benefit in ocular drug delivery.

In 1946 the School of Oriental and African Studies is celebrating the bicentenary of the birth of Sir William Jones: in 1948 University College, London, will celebrate that of Jeremy Bentham. In this there is something more than an accidental approximation of dates. All subsequent scientific English thinking about law is traceable to these two men. The English School of Analytical Jurisprudence; the great tide of law reform which swept through nineteenth-century England; the codification (the word is his own coinage) of law not only in England and India but in many different parts of the world: these things admittedly sprang from the genius of Jeremy Bentham. Sir William Jones's influence was smaller in volume, though almost as widely diffused. He had neither the apostolic fervour of reform nor the overflowing vitality which carried Bentham on with undiminished vigour to eighty-four years: he died before reaching his forty-seventh birthday. But his influence was, none the less, considerable. The first of our Orientalists who was also a lawyer, Colebrooke, Sutherland, Wynch, and other Sanskritists, the Macnaghtens and the Baillies followed in his footsteps. In particular Colebrooke, greatest of them all, and Ian Baillie came directly under his influence. But it is equally true, though less generally recognized, that he is the forerunner of the other great English school of legal philosophy, the historical and comparative school, and that the work of Sir Henry Maine and his successors might have lacked some of its most distinctive elements if Jones's translation had not rendered the Institutes of Manu available to Maine when he was writing Ancient Law. Indeed, Maine's whole career might have been different; for just as his known interest in Oriental legal systems led to Jones's appointment as a judge of the Supreme Court of Calcutta, so it was the interest in Indian ideas evinced in Ancient Law which led to Maine's appointment as law member of the Governor-General's Council, and so to all his later work on similar topics.

ABSTRACT A reference standard is widely sought for use in the quantitative bioassay of pituitary gonadotrophin recovered from urine. The biologic similarity of pooled urinary extracts obtained from large numbers of subjects, utilizing groups of different age and sex, preparing and assaying the materials by varying techniques in different parts of the world, has lead to a general acceptance of such preparations as international gonadotrophin reference standards. In the present study, however, the extract of pooled urine from a small number of young women is shown to produce a significantly different bioassay response from that of the reference materials. Gonadotrophins of individual subjects likewise varied from the multiple subject standards in many instances. The cause of these differences is thought to be due to the modifying influence of non-hormonal substances extracted from urine with the gonadotrophin and not necessarily to variations in the gonadotrophins themselves. Such modifying factors might have similar effects in a comparative assay of pooled extracts contributed by many subjects, but produce significant variations when material from individual subjects is compared. It is concluded that the expression of potency of a gonadotrophic extract in terms of pooled reference material to which it is not essentially similar may diminish rather than enhance the validity of the assay.

This book charts the transformation of one of the world's great religions during an age marked by world wars, genocide, nationalism, decolonization, and powerful ideological currents, many of them hostile to Christianity. The book traces how Christianity evolved from a religion defined by the culture and politics of Europe to the expanding polycentric and multicultural faith it is today—one whose growing popular support is strongest in sub-Saharan Africa, Latin America, China, and other parts of Asia. The book sheds critical light on themes of central importance for understanding the global contours of modern Christianity, illustrating each one with contrasting case studies, usually taken from different parts of the world. Unlike other books on world Christianity, this one is not a regional survey or chronological narrative, nor does it focus on theology or ecclesiastical institutions. The book provides a history of Christianity as a popular faith experienced and lived by its adherents, telling a compelling and multifaceted story of Christendom's fortunes in Europe, North America, and across the rest of the globe. It demonstrates how Christianity has had less to fear from the onslaughts of secularism than from the readiness of Christians themselves to accommodate their faith to ideologies that privilege racial identity or radical individualism.

Presently, various approaches have been exploited in the prolongation of gastric residence time which includes floating drug delivery system (FDDS), swelling and expanding systems, bio-adhesive systems, modified shape systems and high density systems. Among various methods, floating drug delivery system is considered to be a predominant method. Gastric emptying of dosage forms is an extremely varying process and ability to extend and control the emptying time is a valuable resource for the dosage forms. This FDDS is having the ability to provides a solution for this purpose. The FDDS is a bulk density system lower than the gastric fluid, so that the rest will float on the stomach contents for a prolonged period of time and allowing the drug to release slowly at a desired rate from the system and intensifies the bio-availability of the drug having narrow absorption window. The main intension of writing this review on floating drug delivery system is to study the mechanism of flotation to acheive the gastric retention and to discuss briefly about the background of FDDS, advantages and disadvantages, application of FDDS and factors affecting the gastric retension time.

Oral route is presently the gold standard in the pharmaceutical industry where it is regarded as the safest, most economical and most convenient method of drug delivery resulting in highest patient compliance. Over the past three decades, orally disintegrating tablets (FDTs) have gained considerable attention due to patient compliance. Usually, elderly people experience difficulty in swallowing the conventional dosage forms like tablets, capsules, solutions and suspensions because of tremors of extremities and dysphagia. In some cases such as motion sickness, sudden episodes of allergic attack or coughing, and an unavailability of water, swallowing conventional tablets may be difficult. One such problem can be solved in the novel drug delivery system by formulating “Fast dissolving tablets” (FDTs) which disintegrates or dissolves rapidly without water within few seconds in the mouth due to the action of superdisintegrant or maximizing pore structure in the formulation. The review describes the various formulation aspects, superdisintegrants employed and technologies developed for FDTs, along with various excipients, evaluation tests, marketed formulation and drugs used in this research area.
