Vast Antimatter Regions and Scalar Condensate Baryogenesis

The possibility of natural and abundant creation of antimatter in the Universe in a SUSY-baryogenesis model with a scalar field condensate is described. This scenario predicts vast quantities of antimatter, corresponding to galaxy and galaxy cluster scales today, separated from the matter ones by baryonically empty voids. Theoretical and observational constraints on such antimatter regions are discussed.Comment: 7 pages, 2 figures, paper presented at 14th Rencontres de Blois: Matter - Antimatter Asymmetry, Chateau de Blois, France, 17-22 Jun 2002, to be published in the proceedings, ed.

Infekcija virusom Zapadnog Nila s neurološkim poremećajima: prikaz slučaja i kratak pregled stanja u Bugarskoj

A case of a 66-year-old man with West Nile neuroinvassive disease manifested with fever, weakness, fa-tigue, consciousness disorders and underlying diabetes mellitus type 2 and cardiovascular diseases is pre-sented. Laboratory data showed elevated erythrocyte sedimentation rate and fibrinogen. Serological tests revealed West Nile virus specific antibodies of class IgM and IgG in serum. West Nile virus RNA was de-tected in urine sample. Supportive therapy was applied.Prikazuje se slučaj 66-godišnjeg bolesnika s neuroinvazivnom bolešću Zapadnog Nila koja se manifestirala grozni-com, umorom, poremećajem svijesti uz osnovnu bolest dijabetesa tipa 2 i kardiovaskularnom bolešću. Laboratorij-ski podaci pokazali su povišenu sedimentaciju i fibrinogen. Serološki testovi utvrdili su protutijela specifična za virus Zapadnog Nila klase IgM i IgG u serumu.

Theragnostics of TRK-targeting agents (trackins): a challenge that promises reward

Therminologically, theragnostics combines therapeutics and diagnostics. Life at cellular and molecular level is a binary event (e.g., phosphorylation-dephosphorylation of proteins, methylation-demethylations of DNA and acetylation-deacetylation of histones) aimed at the maintenance of a sanogenic phenotype of the homeostasis. Herein, we focus on the neurotrophins with metabotrophic or pathogenic potentials, particularly nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) and their receptors Trk (tyrosine/tropomyosin receptor kinase; pronounced “track”). Accordingly, the term trackins was introduced which stands for Trk-targeting agents influencing agonistically or antagonistically the activity of TrkANGF, TrkBBDNF, and TrkCNT-3 receptor. We argue that multiple diseases may be trackins curable, for instance: (i) agonistic trackins may have therapeutic potentials for cardiometabolic diseases (e.g., atherosclerosis, obesity, T2DM, and metabolic syndrome) and for neurometabolic diseases (e.g., Alzheimer’s disease/T3DM), whereas (ii) antagonistic trackins may be drugs for prostate, breast, gastric, pancreatic and colon cancers, also for pain, and eye, skin and male genitourinary track diseases. Moreover, TrkANGF, TrkBBDNF and TrkCNT-3 receptor may be promising biomarkers for diagnosis and prognosis of these diseases. Altogether, the presented data may be a challenge that promises reward requiring a further pursuit

Postsocialist disability matrix

This paper explores injustices experienced by disabled people in the postsocialist countries of Central and Eastern Europe. Drawing on Nancy Fraser’s theory of social justice, the analysis proposes a ‘matrix’ that reveals the negative impact of two factors – state socialist legacy and postsocialist neoliberalization – on disabled people’s parity of participation in three dimensions of justice – economic redistribution, cultural recognition, and political representation. The legacy of state socialism has underpinned: segregated service provision; medical-productivist understanding of disability for assessment purposes; denial of disability on everyday level; and weak disability organizing. Neoliberal restructuring has resulted in: retrenchment of disability support through decentralization, austerity, and workfare; stigmatization of ‘dependency’ through the discourse of ‘welfare dependency’; responsibilization of disabled people; and depoliticization of disability organizations by restricting their activities to service provision and incorporating them in structures of tokenistic participation. The analysis is informed by reports and academic studies of disability in the postsocialist region

Resurrection and redescription of Varestrongylus alces (Nematoda; Protostrongylidae), a lungworm of the Eurasian moose (Alces alces), with report on associated pathology

Varestrongylus alces, a lungworm in Eurasian moose from Europe has been considered a junior synonym of Varestrongylus capreoli, in European roe deer, due to a poorly detailed morphological description and the absence of a type-series. Methods Specimens used in the redescription were collected from lesions in the lungs of Eurasian moose, from Vestby, Norway. Specimens were described based on comparative morphology and integrated approaches. Molecular identification was based on PCR, cloning and sequencing of the ITS-2 region of the nuclear ribosomal DNA. Phylogenetic analysis compared V. alces ITS-2 sequences to these of other Varestrongylus species and other protostrongylids. Results Varestrongylus alces is resurrected for protostrongylid nematodes of Eurasian moose from Europe. Varestrongylus alces causes firm nodular lesions that are clearly differentiated from the adjacent lung tissue. Histologically, lesions are restricted to the parenchyma with adult, egg and larval parasites surrounded by multinucleated giant cells, macrophages, eosinophilic granulocytes, lymphocytes. The species is valid and distinct from others referred to Varestrongylus, and should be separated from V. capreoli. Morphologically, V. alces can be distinguished from other species by characters in the males that include a distally bifurcated gubernaculum, arched denticulate crura, spicules that are equal in length and relatively short, and a dorsal ray that is elongate and bifurcated. Females have a well-developed provagina, and are very similar to those of V. capreoli. Morphometrics of first-stage larvae largely overlap with those of other Varestrongylus. Sequences of the ITS-2 region strongly support mutual independence of V. alces, V. cf. capreoli, and the yet undescribed species of Varestrongylus from North American ungulates. These three taxa form a well-supported crown-clade as the putative sister of V. alpenae. The association of V. alces and Alces or its ancestors is discussed in light of host and parasite phylogeny and host historical biogeography. Varestrongylus alces is a valid species, and should be considered distinct from V. capreoli. Phylogenetic relationships among Varestrongylus spp. from Eurasia and North America are complex and consistent with faunal assembly involving recurrent events of geographic expansion, host switching and subsequent speciation.
