The genus Drosophila has played an essential role in many biological studies during the last 100 years but much controversy and many incompletely addressed issues still remain to be elucidated regarding the phylogeny of this genus. Because information on the Neotropical species contained in the subgenus Drosophila is particularly incomplete, with this taxonomic group being underrepresented in m...

Two new cobaltous-porphyrin complexes, namely (?-piperazine)-bis[(meso-tetra(para-methoxyphenyl)porphyrinato)]cobalt(II) and (piperazine)[meso-tetra(para-chlorophenyl)porphyrin]cobalt(II) dichloromethane disolvate, with the formulas [{CoII(TMPP)}2(?2-pipz)] (complex 1) [CoII(TClPP)(pipz)]·2CH2Cl2 2), were used efficiently as catalysts in degradation of 4-nitrophenol (4-NP) an aqueous hydrogen p...

Two isostructural 1D compounds {[M3(hpdc)2(H2O)6] 2H2O}n (M = Mn, Co; H3hpde = 2-hydroxypyrimidine-4,6-dicarboxylic acid) were synthesized by the in situ hydrothermal reactions of 2-chloropyrimidine-4,6-dicarboxylic acid with MCl2 (M = Mn, Co) and NaOH; the MnII compound shows spin-canted antiferromagnetism, whereas the CoII compound exhibits the coexistence of spin-canting and a two-step field...

Pulse dipolar electron paramagnetic resonance spectroscopy (PDS) is continuously furthering the understanding of chemical and biological assemblies through distance measurements in nanometer range. New paramagnets pulse sequences can provide structural insights not accessible other techniques. In pursuit alternative spin centers for PDS, we synthesized a low-spin CoII complex bearing nitroxide ...

Rheumatoid arthritis (RA) that affects the synovial knee joint causes swelling of membrane and tissue damage. Interleukin-17A (IL-17A) enzyme glycogen synthase kinase-3β (GSK3β) are involved in pathogenesis RA. The link between IL-17A, GSK3β, oxidative stress, profibrogenic marker alpha-smooth muscle actin (α-SMA) with without TDZD-8, GSK3β inhibitor has not been studied before. Consequent...

The synthesis and the structure of the new potentially heptadentate ligand 1,3-bis-(3-oxo-3-(2-hydroxyphenyl)-propionyl)-2-methoxybenzene (H5L) is described. The reaction in pyridine or DMF of this ligand with various M(AcO)2 salts (M = NiII, CoII, MnII) leads to very different products depending on the metal. Thus, the dinuclear complexes [M2(H3L)2(py)4] (M = NiII, 1; CoII, 2) or the linear zi...

The complete DNA sequence of the mtDNA cytochrome oxidase II gene from house fly, Musca domestica, face fly, Musca autumnalis, stable fly, Stomoxys calcitrans, horn fly, Haematobia irritans, and black garbage fly, Hydrotaea aenescens, are reported. The nucleotide sequence codes for a 229 amino acid peptide. The COII sequence is A + T rich (74.1%), with up to 12.3% nucleotide and 8.4% amino acid...
