Source/Description: A 3.6 kb EcoRI fragment (lambda ABL3) containing portions of exons 7 and 8 and the intervening intron of the ABL oncogene was isolated from a chromosome 9-specific library (ATCC # LA09NS01) using a 1.7 kb Abelson murine leukemia virus probe (v-abl, ONCOR, Inc.). A single copy 1.8 kb BglII fragment (ABL3) was derived from the original lambda clone and detects the StuI RFLP. P...

Angiotensin II (Ang II) produces a positive inotropic effect on the heart; however, its usefulness as an inotropic agent is limited because of its inherent vasoconstrictor action. We therefore designed Ang II analogues that are potent, positive inotropic agents with minimal myotropic properties. Replacement of the proline residue in position 7 with alanine reduced the pressor and vascular contr...

INTRODUCTION The pedunculopontine nucleus (PPN), co-localized with the mesencephalic locomotor region, has been proposed as a key structure in the physiopathology of Parkinson's disease. OBJECTIVES The goal of the present study was to assess if the aminoacid neurotransmitter release in the PPN is modified by the degeneration of dopaminergic cells, from substantia nigra pars compacta in 6-hydr...

Abstract Carbon quantum dots (CQD) were prepared from three different precursors and by bottom-up synthesis methods: classical pyrolysis of citric acid (CAP), microwave irradiation glucose (GM), hydrothermal treatment glucosamine hydrochloride (GAH). CQD further functionalized using various nitrogen-containing compounds: 6-aminohexanoic acid, 1,6-diaminohexane, N-octylamine, dimethylamine, tryp...

BACKGROUND TH1 immune response antagonism is a desirable approach to mitigate some autoimmune and inflammatory reactions during the course of several diseases where IL-2 and IFN-gamma are two central players. Therefore, the neutralization of both cytokines could provide beneficial effects in patients suffering from autoimmune or inflammatory illnesses. RESULTS A chimeric antagonist that can a...

A multi-histidinic peptide and its minimal models have been investigated for Zn(ii) binding. We have used NMR spectroscopy to probe the binding of zinc to the three repeats (T(1)R(2)S(3)R(4)S(5)H(6)T(7)S(8)E(9)G(10))(3) and to its mono-histidinic minimal models, the 9- and 10-aminoacid fragment. (1)H-(1)H TOCSY, (1)H-(13)C HSQC, (1)H-(1)H NOESY and (1)H-(1)H ROESY multidimensional NMR technique...
