According to the WHO/EORTC classification, lymphomatoid papulosis (LyP) is a recurrent, selfhealing papular eruption belonging to the spectrum of cutaneous CD30+ lymphoproliferative disorders. The neoplastic cell is typically a CD4+ T-lymphocyte, also manifesting CD30 expression. Three main histologic subtypes are recognized: type A (histiocytic), type B (mycosis fungoides-like), and type C (an...

As the author has written, it is the modern developments in medicine which have completely displaced the use of pomanders for therapeutic and prophylactic purposes, but at one time the matter was quite otherwise. From at least the days of the Ebe...

The prehistoric discovery that certain plants cause harm and others have curative powers is the origin of the healing professions and its practitioners (priest, physician, and apothecary), as well as professions devoted to plants (botany and horticulture). The description of plants and their properties and virtues (termed herbals in the 16th century) became an invaluable resource for the physic...

The evolution of lacrimal disorders and its management amply exemplifies the above stated quote of the 20th century British philosopher Bertrand Russell. Lacrimal surgeries have been a subject of discussion in antiquity with the earliest documented reference being a lacrimal sac incision in the ‘Code of Hammurabi’ in 2250 BC. The past which appears glorious today had once traveled through many ...

Evidence of the use of plants for medicinal purposes dates as far back as 60 000 years ago (1) in both western and eastern cultures; in both developed and undeveloped countries. For example, the pharmacopoeia of Emperor Shen Nung of China, around 2730–3000 BC, describes the medicinal use of plants such as Hemp, Aconite, Opium. The Egyptian Pharmacopoeia of Ebers Papyrus, written about 1500 BC, ...

The past decades yielded fundamental changes to the ways in which value creation is being organized. Globalization and market deregulation motivate businesses to expand into new, often remote markets, which requires them to decentralize and distribute work and often to partner with local organizations, which in turn brings with it changes to the ways in which people need to organize their work ...

I MAKE no apology for speaking to you tonight in my presidential address on diabetes. During more than thirty years I have done much work at this disease, having seen more than ten thousand cases of it in all, and having been concerned in its investigation and treatment both in the pre-insulin and insulin eras. At the beginning of my medical life very little in the way of practical useful treat...

The use of herbal medicines has been documented throughout recorded history including Assyrian clay tablets (2000 BC) and the Egyptian Ebers Papyrus (1550 BC) and in Ayurveda works from 900 BC. Arab scholars in Europe kept detailed notes regarding the use of medicinal plants. In the modern era, the research of natural bioactive molecules began with the isolation of morphine from opium latex in ...

Overview All animals are equipped with the capacity for rapid motor response that excitable cells-nerve and muscle-mediate. Voltage-sensitive ion channels on the surface membranes allow the cells to generate brief and reversible alterations of the voltage (action potentials) along the surface of these cellular cables. Ion channels, notably those conducting Na +, Ca 2+, and W, are large proteins...
