‘Spirit Verse’ Apocryphal Poems and Marketing in Composing Lizzie Doten’s Poems from the Inner Life مشاعل ابراهيم الحماد

Presented in the MA conference at the university of Leeds, this paper is concerned with the trance medium Lizzie Doten’s book Poems from the Inner Life published in 1863 and her peculiar claim about the origins of a majority of these poems. She claims that the majority of her poems were dictated to her through speaking (while in a trance state of being) with the spirits of well-known poets, including Edgar Allan Poe. While her claim includes dead poets other than Poe, such as William Shakespeare and Robert Burns, the majority of the poems in this book were attributed to Poe’s spirit. Thus, by combing the two phenomena, spiritualism and Edgar Allan Poe, she has composed her book, Poems from the Inner Life.

My Poor, Un-white Thing: Skin Colour as a Traumatic Symptom in Nella Larsen’s Passing, Toni Morrison’s The Bluest Eye and Chinelo Okparanta’s ‘Fairness’ مشاعل ابراهيم الحماد

My MA dissertation focuses on the effects of slavery on the writings of female African Americans in different time periods. I argue that slavery creates a scar that can be still traced in the psyches of female African Americans by analysing the way they write about skin colour. Seeing skin colour as a post-traumatic symptom of slavery, I argue that slavery still hunts the lives of African Americans.

Phytochemical Screening and Gastroprotective Effect of the aerial Parts of Salasola terrandraForssk.against Aspirin Induced Gastric Ulceration in Rats أمينه عبدالرحمن المشحن

Gastric ulcers are a common disorder of the entire gastrointestinal tract that occurs mainly in the stomach and the proximal duodenum. This disease is multifactorial and its treatment faces great difficulties due to the limitedeffectiveness and severe side effects of the currently available drugs (Mota et al., 2009).

Aspirin is a potent non-steroidal anti-inflammatory drug (NSAID) that is used for the treatment of rheumatoid arthritis and related diseases as well as the prevention of cardiovascular thrombotic diseases. Gastric ulcer associated with the use of aspirin is a major problem. Many factors such as gastric acid and pepsin secretion, gastric microcirculation, prostaglandin E2 (PGE2) content (Laine, et. al., 2008) and proinflammatorycytokines interleukin (IL-1β) and tumor necrosis factor (TNF) –α play important role in the genesis of gastric mucosal damage and its subsequent development (Wang, et al. 2007;  Wallace 2008).

Plant extracts are attractive sources of new drugs and have been shown to produce promising results in the treatment of gastric ulcers (Al kathar and Munir, 1989). Numerous plants and herbs are used to treat gastrointestinal disorders in traditional medicine (Schmeda-Hirschmann and Yesilada, 2005; Mota et al., 2009).

The genus Salsola, family Chenopodiaceae (Goosefoot family) consists of over100species found in the dried regions of Asia, Europe and Africa [El Hadidi& Fayed, 1994; Boulos, 1995]. Some Salsola plants are widely used as folk medicine for the treatment of hepatitis [Abegaz & Woldu,1991]; or infections caused by tapeworm andparasites [Saratikov & Vengerovskil, 1995]; they also have pronounced vasoconstrictive, hypertensive, and cardiac stimulant action [Beyaoui, et al, 2012]...

Variations in Site of Lithiation of N [2 (4 Methoxyphenyl)ethyl]pivalamide Use in Ring Substitution محمد بطاح الشمري

Lithiation of N-[2-(4-methoxyphenyl)ethyl]pivalamide at –20 to 0 °C with three equivalents of n-BuLi in anhydrous THF, followed by reactions with various electrophiles, gives high yields of products involving ring substitution ortho to the pivaloylaminoethyl group, which was unexpected in view of earlier results reported with t-BuLi.

Lateral lithiation and substitution of N'-(2-methylphenyl)-N,N-dimethylurea محمد بطاح الشمري

Lithiation of N'-(2-methylphenyl)-N,N-dimethylurea with three molar equivalents of tert-butyllithium at 40 to 30 C takes place on the nitrogen and on the methyl group at position 2 of the phenyl group. The lithium intermediate thus obtained reacts with a variety of electrophiles to give the corresponding side-chain substituted derivatives in high yields.

Control of Site of Lithiation of 3-(Aminomethyl)pyridine Derivatives محمد بطاح الشمري

Lithiation of N-(pyridin-3-ylmethyl) pivalamide, tert-butyl N-(pyridin-3-ylmethyl) carbamate, and N,N-dimethyl-N′-(pyridin-3-ylmethyl)urea with tert-butyllithium (3 equiv) in anhydrous tetrahydrofuran at –78 °C takes place on the nitrogen and on the ring at the 4-position. The dilithium reagents thus obtained react with various electrophiles to give the corresponding substituted derivatives in high yields. On the other hand, regioselective side-chain lithiation occurs with lithium diisopropylamide (3.3 equiv) at –20 to 0 °C. A mixture of ring and side-chain substitution products is obtained with n-butyllithium as the lithium reagent. Treatment of one of the ring-substituted products with trifluoroacetic anhydride in dichloromethane under reflux conditions led to formation of the corresponding 1H-pyrrolo[3,4-c]pyridine in high yield.

Directed Lithiation of N′-[2-(4-Methoxyphenyl)ethyl]-N,N-dimethylurea and tert-Butyl [2-(4-Methoxyphenyl)ethyl]carbamate محمد بطاح الشمري

 N'-(2-(4-Methoxyphenyl)ethyl)-N,N-dimethylurea and tert-butyl (2-(4- methoxyphenyl)ethyl)carbamate are doubly lithiated on the nitrogen and ortho- to the directing metalating group at -20 to 0 oC with three mole equivalents of n-BuLi in anhydrous THF. Reactions of the dilithium reagents produced in situ with various electrophiles give high yields of the corresponding substituted products. In the case of the urea, side-products due to lithiation and substitution on one of the methyl groups of the urea unit are obtained in low yields (0-17%).
