Atomic layer etching (ALE) typically divides the etching process into two self­limited reactions. One reaction passivates a single layer of material while the second preferentially removes the passivated layer. As such, under ideal conditions the wafer scale uniformity of ALE should be independent of the uniformity of the reactant fluxes onto the wafers, provided all surface reactions are satur...

BACKGROUND Alendronate (ALE) is a conventional drug used to treat osteoporosis. Low-magnitude whole-body vibration (WBV) exercise has been developed as a potential treatment for osteoporosis. The aim of this study was to investigate whether low-magnitude WBV could enhance the protective effect of ALE on bone properties in ovariectomized rats. METHODS A total of 128 Sprague-Dawley rats were ra...

Chrysophyllum cainito L., a traditional herbal medicine, could have the potential for management of hypertension due to presence of polyphenolic compounds. The extracts and fractions of the pulp of plant were evaluated for in vitro (inhibition of angiotensin I converting enzyme/ACE assay), ex vivo (isolated aorta relaxation assay) and in vivo (salt induced hypertensive rat assay). The alcoholic...

BACKGROUND 5-Fluoro-2'-deoxyuridine (5-FdU), a drug against gastric cancer, was covalently linked via its nucleobase with the amino-bisphosphonate alendronate (Ale), resulting in a new antimetabolite-bisphosphonate conjugate (5-FdU-Ale), designed for bone-targeting. MATERIALS AND METHODS The cytostatic effect of 5-FdU-Ale was evaluated in vitro compared to monomers and mixtures using CASY Tec...

Silene is represented by c. 110 species in flora of Iran which growing mainly in the mountainous areas. During several expeditions to different regions of Iran (Tehran, Semnan, Kerman, Kermanshah and Kohgiluyeh va Boyer-Ahmad Provinces) some interesting specimens were collected. S. caucasica, is introduced as a new record for the flora of Iran. Five interesting and very restricted Iranian endem...

This paper summarises the features of my paper, 'Voluntary Active Euthanasia', and a later jointly authored paper, 'Moral Fictions', which I believe are examples of good medical ethics.
