Human histo (blood) group O(H) and phenotype-determining enzymes in growth and infectious disease

Peter Arend
The human ABO(H) blood group phenotypes arise from the evolutionarily oldest genetic system found in primate populations, and the blood group antigen A represents the ancestral primordial structure, while under the selective pressure of life-threatening diseases blood group O(H) came to dominate as the most common blood group worldwide. Non-O(H) phenotypes demonstrate impaired formation of adaptive and innate immunoglobulin specificities due to clonal selection and phenotype formation in plasma proteins. Compared with individuals with blood...

Biometric Iris Recognition Based on Hybrid Technique

Khattab M. Ali Alheeti
Iris Recognition is one of the important biometric recognition systems that identify people based on their eyes and iris. In this paper the iris recognition algorithm is implemented via histogram equalization and wavelet techniques. In this paper the iris recognition approach is implemented via many steps, these steps are concentrated on image capturing, enhancement and identification. Different types of edge detection mechanisms; Canny scheme, Prewitt scheme, Roberts scheme and Sobel scheme are used to detect...

Tricarbonylrhenium(I) complexes with the N,6-dimethylpyridine-2-carbothioamide ligand: combined experimental and calculation studies

Krzysztof Lyczko, Monika Lyczko, Sylwia Meczynska-Wielgosz, Marcin Kruszewski & Józef Mieczkowski
A new series of tricarbonyl complexes of rhenium(I) in the “2 + 1” system with the bidentate ligand N,6-dimethylpyridine-2-carbothioamide ((CH3)NC5H4-CS-NH-CH3, MeLH(Me)NS) and a monodentate ligand (halides Cl, Br, or I, and the pseudohalide NCS anion) was synthesized. The use of mixed ligands led to the formation of neutral tricarbonylrhenium(I) complexes [Re(CO)3(MeLH(Me)NS)X] (X = Cl, Br, I, NCS) (1–4). Single-crystal X-ray diffraction was used to determine the crystal structures of all four compounds and those results were compared with molecular...

CO2 activation by metalligand-cooperation mediated by iridium pincer complexes

Moran Feller, Eyal Ben-Ari, Yael Diskin-Posner & David Milstein
Herein we report the reversible activation of CO2 by the dearomatized complex [(tBuPNP*)Ir(COE)] (1) and by the aromatized complex [(tBuPNP)Ir(C6H5)] (2) via metal-ligand cooperation (MLC) (tBuPN = 2,6-bis-(di-tert-butylphosphinomethyl)pyridine; tBuPNP* = deprotonated PNP; COE = cyclooctadiene). The [1,3]-addition of CO2 to 1 and 2 is reversible at ambient temperature. While the dearomatized complex 1 reacts readily at ambient temperature with CO2 in THF or benzene, complex 2 reacts with CO2 upon heating in benzene at 80 °C or at ambient temperature...

Copper(I) bromide and chloride complexes with urotropine and triethylenediamine: Synthesis, crystal structure, and Raman characterization*

Andrii Vakulka & Evgeny Goreshnik
In the present study, the oxidative dissolution of metallic copper has been explored with the intention to prepare some new complexes with urotropine (hmta) and triethylenediamine (dabco) ligands. All the compounds synthesized were characterized by single crystal X-ray diffraction and Raman spectroscopy. Reactions performed in a DMSO/CuCl2∙2H2O mixture resulted in [(μ-Cl)2CuI(hdabco+)CuI(μ-Cl)(κS-DMSO)]n and [CuICl(hmta)2] complexes. Their isostructural bromide analogues [(μ-Br)2CuI(hdabco+)CuI(μ-Br)(κS-DMSO)]n and [CuIBr(hmta)2] were prepared by the reaction of elemental copper with respective ligands in a DMSO/CBr4...

Reaction rate theory for supramolecular kinetics: application to protein aggregation

Thomas C. T. Michaels, Lucie X. Liu, Samo Curk, Peter G. Bolhuis, Anđela Šarić & Tuomas P. J. Knowles
Probing reaction mechanisms of supramolecular processes in soft and biological matter, such as protein aggregation, is inherently challenging. This is because these processes involve multiple molecular mechanisms that are associated with the rearrangement of large numbers of weak bonds, resulting in complex free energy landscapes with many kinetic barriers. Reaction rate measurements at different temperatures can offer unprecedented insights into the underlying molecular mechanisms. However, to be able to interpret such measurements, a key challenge...

Seasonal variations in the diet and food selection of the Algerian hedgehog Atelerix algirus

Chafika Mouhoub-Sayah, Hafsa Djoudad-Kadji, Florian Kletty, André Malan, Jean-Patrice Robin, Michel Saboureau & Caroline Habold
The Algerian hedgehog Atelerix algirus is an insectivorous species. However, the exact composition of its natural diet remains largely undetermined, especially in relation to seasonal variations in food availability. From March to November, we simultaneously analysed the composition of 180 hedgehog faecal samples and food availability in the Soumman Valley, Algeria to assess food selection in this species. The faeces contained 196 different prey species, of which 92% belonged to the class Insecta. The highest...

First genetic data for band-winged grasshoppers (Orthoptera: Acrididae: Oedipodinae) of the Biskra region of Algeria with new records for the country

Abdelhamid Moussi, Lara-Sophie Dey, Daniel Petit, Abderrahmane Abba, Robert Klesser & Martin Husemann
DNA barcoding represents an objective tool for fast species identification, especially for taxa for which morphological identification is difficult. One current limitation of barcoding is the lack of reference sequences for many groups. While many European and North American countries have started their own barcoding initiatives to generate complete local inventories and databases, such efforts are sparse for African, Asian and South American countries, despite their high biodiversity and comparably poorly explored faunas. Therefore, it...

Box-ticking and Olympic high jumping – Physicians’ perceptions and acceptance of national physician validation systems

Carolin Sehlbach, Marjan J. B. Govaerts, Sharon Mitchell, Gernot G. U. Rohde, Frank W. J. M. Smeenk & Erik W. Driessen
Purpose: National physician validation systems aim to ensure lifelong learning through periodic appraisals of physicians’ competence. Their effectiveness is determined by physicians’ acceptance of and commitment to the system. This study, therefore, sought to explore physicians’ perceptions and self-reported acceptance of validation across three different physician validation systems in Europe. Materials and methods: Using a constructivist grounded-theory approach, we conducted semi-structured interviews with 32 respiratory specialists from three countries with markedly different validation systems: Germany,...
