risalat risalat al-ghofran is the letter that abu ala marri (363-449 ah) writes in response to a letter from ali ben mansour halabi. inspired by the story of his ascension and the quran makes for a very long introduction to this thesis imaginary journey to heaven and hell are brought into the picture and verses and poems, and news and conflict in many lexical and syntactic text instead gives it...

To study the structural and functional roles of the cysteine residues at positions 36, 41, and 46 in the transmembrane domain of phospholamban (PLB), we have used Fmoc (N-(9-fluorenyl)methoxycarbonyl) solid-phase peptide synthesis to prepare alpha-amino-n-butyric acid (Abu)-PLB, the analogue in which all three cysteine residues are replaced by Abu. Whereas previous studies have shown that repla...

The Jarrah forest of southwestern Australia supports mineral and timber production and provides important food plants for three threatened black-cockatoo species. To assist the integration of conservation and production objectives, we studied the landscape distribution of two important black-cockatoo food sources, the eucalypts Jarrah Eucalyptus marginata and Marri Corymbia calophylla, at a min...

the history of jahangosha is a literary-historical work created byata malik joweini using verbal and spiritual industries and several metaphors and allegories from different quranic and islamic traditions and persian and arabic poems. one important aspect of this work, adducing or borrowing from arabic distiches, is going to be analyzed in this paper. joweini has used many different arabic vers...

The conformational behaviour of delta Ala has been investigated by quantum mechanical method PCILO in the model dipeptide Ac-delta Ala-NHMe and in the model tripeptides Ac-X-delta Ala-NHMe with X = Gly, Ala, Val, Leu, Abu and Phe and is found to be quite different. The computational results suggest that in the model tripeptides the most stable conformation corresponds to phi 1 = -30 degrees, ps...

Mersacidin belongs to the type B lantibiotics (lanthionine-containing antibiotics) that contain post-translationally modified amino acids and cyclic ring structures. It targets the cell wall precursor lipid II and thereby inhibits cell wall synthesis. In light of the emerging antibiotics resistance problem, the understanding of the antibacterial activity on a structural basis provides a key to ...

Urinary tract infections (UTIs) are among the most common infectious diseases of humans, with Escherichia coli being responsible for >80% of all cases. Asymptomatic bacteriuria (ABU) occurs when bacteria colonize the urinary tract without causing clinical symptoms and can affect both catheterized patients (catheter-associated ABU [CA-ABU]) and noncatheterized patients. Here, we compared the vir...
