RESEARCH PAPERS' Proteins Generation of forms of fragment E with differing thrombin-binding properties during digestion of fibrinogen by plasmin Association between diphtheria toxin Aand B-fragment and their fusion proteins The interplay of temperature and protons in the modulation of oxygen binding by squid blood Interaction between secretory leucocyte proteinase inhibitor and bronchial mucins...

Hereby, we objectively assessed the outcomes of a facial-lifting procedure with Botulinum toxin type A (BoNT-A)using 3D stereophotogrammetry quantification (3D-SQ). 46-year-old female patient received full faceBoNT-A treatment in total dose 180 Speywood Units (sU). Frontal, lateral and oblique photographs weretaken before 20 days after treatment, at rest during mimic movements. Also, facial sca...

We give geometric explanations and proofs of various mirror symmetry conjectures for T-invariant Calabi-Yau manifolds when instanton corrections are absent. This uses fiberwise Fourier transformation together with base Legendre transformation. We discuss mirror transformations of (i) moduli spaces of complex structures and complexified symplectic structures, Hp,q’s, Yukawa couplings; (ii) sl (2...

Three distinct tubulin proteins are essential for microtubule function: a-, b-, and g-tubulin. After translation, aand b-tubulin proteins combine into a soluble, 7 S heterodimer that is multimerized to form the microtubule filament. Conversely, g-tubulin combines with several proteins into a soluble, 25 S multi-protein particle, the gammasome that is essential for nucleating microtubule filamen...

Background: T-2 mycotoxin belongs to the Trichothecene family and has damaging effects on the immune system. Objective: To investigate the toxic effect of T-2 toxin on the percentage of peripheral blood B lymphocytes and the potential protective role of selenium and vitamin E. Method: Frequencies of B lymphocytes (CD19+ ) were analyzed after injection of sublethal doses of T-2 toxin into Balb/c...

–In the human thalamic ventralis lateralis nucleus the responses of 184 single units to verbally ordered voluntary movements and some somatosensory stimulations were studied by microelectrode recording technique during 38 stereotactic operations on parkinsonian patients. The tests were carried out on the same previously examined population of neurons classified into two groups, named Aand B-typ...

McGoogan, Jennifer M., and Vincent M. Cassone. Circadian regulation of chick electroretinogram: effects of pinealectomy and exogenous melatonin. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R1418–R1427, 1999.—Melatonin is an important component of the avian circadian system. This study investigates the effects of pinealectomy (Pin-X) and melatonin implantation (Mel) on electr...

cules resembling neuropeptides (Petrenko et al., 1996; Neurexins are expressed in hundreds of isoforms on Missler and Südhof, 1998b). Single LNS domains are the neuronal cell surface, where they may function sufficient for ligand binding. b-neurexin containing a as cell recognition molecules. Neurexins contain LNS sole LNS domain binds a-latrotoxin and neuroligin (Ichtdomains, folding units fou...

A B S T R A C T Human hemoglobin messenger RNA was isolated by sucrose gradient centrifugation from reticulocytes of patients having various hemolytic anemias. Using a messenger RNA-dependent cell-free system derived entirely from rabbit reticulocytes, the human hemoglobin messenger RNA has been translated and the products analyzed by carboxymethylcellulose column chromatography. Normal messeng...
