Heterodinuclear complexes, syn-[MPt(μ-pyt)2(bpy)2](n+) (syn-[MPt], M = Pd(2+), Au(3+), Hpyt = pyridine-2-thiol, bpy = 2,2'-bipyridine), were synthesized as a selective geometrical isomer by stepwise complexation. X-ray analyses of the hexafluorophosphate salts of these complexes proved their dinuclear structures with short M···Pt distances (2.9084(4) Å for syn-[PdPt] and 2.9071(4) Å for syn-[Au...

The aggregation of alpha synuclein (α-syn) is a neuropathological feature that defines a spectrum of disorders collectively termed synucleinopathies, and of these, Parkinson's disease (PD) is arguably the best characterized. Aggregated α-syn is the primary component of Lewy bodies, the defining pathological feature of PD, while mutations or multiplications in the α-syn gene result in familial P...

Huntington's disease (HD) is the most common of nine inherited neurological disorders caused by expanded polyglutamine (polyQ) sequences which confer propensity to self-aggregate and toxicity to their corresponding mutant proteins. It has been postulated that polyQ expression compromises the folding capacity of the cell which might affect other misfolding-prone proteins. α-Synuclein (α-syn) is ...

The genus Sericomyrmex Mayr (Formicidae: Myrmicinae: Attini) is a Neotropical group of fungus-farming ants known for its problematic taxonomy, caused by low morphological variability across the species, vague and old species descriptions, and an outdated and incomplete key published in 1916. Recent molecular studies revealed that Sericomyrmex is the product of a rapid recent radiation, with a d...

Alpha-synuclein (α-Syn) is a major component of Lewy bodies, abnormal protein aggregates that are present in neurons of patients with Parkinson's disease and other neurological disorders. Despite intensive investigation, the in vivo role of α-Syn in physiological and pathological processes is not fully understood. This study addresses a current debate on the nuclear localization of α-Syn protei...

Palaearctic species of the weevil genus Mecinus Germar, 1821 are revised. A total of 47 species are recognized, one of which, M. baridioides sp. n. is new to science. Mecinus dorsalis var. tavaresi Hoffmann, 1958 (stat. rev.) is considered as a distinct species, whereas M. alboscutellatus var. atratulus (Solari, 1933) is maintained as a subspecies of M. alboscutellatus (Hustache, 1913). The fol...

α-Syntrophin (α-syn), a scaffold protein, links signaling molecules to the dystrophin-glycoprotein complex. Absence of α-syn from the DGC is known to lead to structurally aberrant neuromuscular junctions (NMJs) with few acetylcholine receptors (AChRs) clustered at synaptic sites. Using α-syn knock-out mice, we show that during the first postnatal week, α-syn is not required for synapse formatio...

THE FOLLOWING TAXONOMIC OR NOMENCLATURAL CHANGES ARE PROPOSED Themus (s.str.) regalis (Gorham, 1889), nom. rest.; Themus (s.str.) scutulatus Wittmer, 1983 = Themus (s.str.) hmong Kazantsev, 2007, syn. n.; Themus (Telephorops) coelestis (Gorham, 1889) = Themus violetipennis Wang & Yang, 1992, syn. n.; Themus (Telephorops) uniformis Wittmer, 1983, stat. n. = Themus (Telephorops) cribripennis Witt...

Distributed Denial-of-Service (DDoS) attack remains a serious problem on the Internet today, as it takes advantage of the lack of authenticity in the IP protocol, destination oriented routing, and stateless nature of the Internet. Among various DDoS attacks, the TCP SYN flooding [1] is the most commonly-used one. It exploits TCP’s three-way handshake mechanism and TCP’s limitation in maintainin...

A critical and annotated catalogue of 183 types of HymenopteraChrysididae belonging to 124 taxa housed in the Radoszkowski collection is given. Radoszkowski type material from other institutes has also been checked. Six lectotypes are designated in Kraków (ISEA-PAN): Chrysisacceptabilis Radoszkowski, 1891; Chrysispersica Radoczkowsky, 1881; Chrysisdaphnis Mocsáry, 1889; Chrysislagodechii Radosz...
