Rosyjski korpus posiłkowy (auksyliarny) na służbie Augusta II w Rzeczypospolitej i Saksonii. Nowe spojrzenie na sasko-polsko-rosyjską współpracę poli…

2019

Polityczno-militarna współpraca sasko-polsko-rosyjska od początku wielkiej wojny północnej (1700–1721) nie układała się po myśli Augusta II, który ponosił klęski w starciach z wojskami Karola XII i po przegranej Piotra I pod Narwą w 1700 roku wziął na siebie główny ciężar wojny. Próbą wspomożenia armii saskiej Augusta II przez cara, który obawiał się zawarcia przez władcę sasko-polskiego separatystycznego pokoju z królem szwedzkim, i chciał także zaangażowania w konflikt Rzeczypospolitej, było zorganizowanie rosyjskiego korpusu posiłkowego (auksyliarnego), który z perspektywy czasu okazał się zabiegiem politycznym, a w mniejszym stopniu wojskowym. W zaprezentowanym artykule recenzyjnym prob…

Massive presence of insertion sequences in the genome of SOPE, the primary endosymbiont of the rice weevil Sitophilus oryzae

2008

Bacteria that establish an obligate intracellular relationship with eukaryotic hosts undergo an evolutionary genomic reductive process. Recent studies have shown an increase in the number of mobile elements in the first stage of the adaptive process towards intracellular life, although these elements are absent in ancient endosymbionts. Here, the genome of SOPE, the obligate mutualistic endosymbiont of rice weevils, was used as a model to analyze the initial events that occur after symbiotic integration. During the first phases of the SOPE genome project, four different types of insertion sequence (IS) elements, belonging to well-characterized IS families from alpha-proteobacteria, were ide…

Structure of SNX9 SH3 in complex with a viral ligand reveals the molecular basis of its unique specificity for alanine-containing class I SH3 motifs

2021

Class I SH3 domain-binding motifs generally comply with the consensus sequence [R/K]x0PxxP, the hydrophobic residue 0 being proline or leucine. We have studied the unusual 0 = Ala-specificity of SNX9 SH3 by determining its complex structure with a peptide present in eastern equine encephalitis virus (EEEV) nsP3. The structure revealed the length and composition of the n-Src loop as important factors determining specificity. We also compared the affinities of EEEV nsP3 peptide, its mutants, and cellular ligands to SNX9 SH3. These data suggest that nsP3 has evolved to minimize reduction of conformational entropy upon binding, hence acquiring stronger affinity, enabling takeover of SNX9. The R…

Pathogenicity bioassays of isolates of Beauveria bassiana on Rhynchophorus ferrugineus

2012

BACKGROUND:The control ofRhynchophorusferrugineus (Olivier), themainpalmpest in theMediterraneanBasin, is problematic because of its biology and the current restrictions inmany European countries on the use of chemical insecticides in urban areas. Entomopathogenic fungi have been studied as potential biological control agents, but information on their natural incidence is limited. Strains of Beauveria bassiana (Balsamo) Vuillemin were isolated from symptomatic insects collected on dead palms, and their pathogenicity against different instars of R. ferrugineus was evaluated in the laboratory. RESULTS: The overall percentage of infected insects found in Canary palms was 7%. In laboratory bioa…

Toxicity of five Cry proteins against the insect pest Acanthoscelides obtectus (Coleoptera: Chrisomelidae: Bruchinae).

2019

Abstract The beetle Acanthoscelides obtectus (Say) causes severe post-harvest losses in the common bean (Phaseolus vulgaris). Under laboratory conditions, the susceptibility of A. obtectus to five coleopteran-specific Cry toxic proteins from Bacillus thuringiensis (Cry1Ba, Cry1Ia, Cry3Aa, Cry7Ab, and Cry23/37) was evaluated. After 30 days exposure, Cry proteins demonstrated high activity against A. obtectus adults (100% mortality). Proteins showed statistical differences in toxicity parameters compared to the control treatment, but the parameters were similar among them, and indicated that the final toxic effects can be observed after the 24th day. The toxic effects on A. obtectus larvae we…

Two, three, many body systems involving mesons

2011

In this talk we show recent developments on few body systems involving mesons. We report on an approach to Faddeev equations using chiral unitary dynamics, where an explicit cancellation of the two body off shell amplitude with three body forces stemming from the same chiral Lagrangians takes place. This removal of the unphysical off shell part of the amplitudes is most welcome and renders the approach unambiguous, showing that only on shell two body amplitudes need to be used. Within this approach, systems of two mesons and one baryon are studied, reproducing properties of the low lying $1/2^+$ states. On the other hand we also report on multirho and $K^*$ multirho states which can be asso…

Revisional bariatric surgery due to failure of the initial technique: 25 years of experience in a specialized Unit of Obesity Surgery in Spain.

2019

Abstract Objectives To evaluate the effectiveness of conversion surgery in a bariatric surgery unit with 25 years of experience. Method Retrospective observational study of patients with type II obesity or higher who were reoperated by means of conversion surgery due to weight regain, residual body mass index (BMI) >35 kg/m2 or Results A total of 112 patients were included, with a mean age of 40.2 years, who initially underwent vertical banded gastroplasty (VBG) (32.1%), gastric banding (GB) (23.2%), Roux-en-Y gastric bypass (RYGB) (21.4%) and sleeve gastrectomy (SG) (23.2%). The conversion techniques, with a median time between the two surgeries of 70 months, included: RYGB, SG, one-anasto…

E se il punteruolo affamasse Steinernema carpocapsae?

2023

Rhynchophorus ferrugineus (Olivier 1790) (Coleoptera: Curculionidae), phytophagus of palms, has been used as a model to deepen the knowledge of the host-entomopathogen relationship. The effects of Steinernema carpocapsae (Nematoda: Steinernematidae) on the growth and immunoactivity of R. ferrugineus larvae were compared with another model insect Galleria mellonella L. (Lepidoptera: Pyralidae). Although S. carpocapsae had a negative effect on the weight and mortality of R. ferrugineus, it was not able to replicate in the hemolymph with the same rates found for the moth. In vivo and in vitro effects of S. carpocapsae on the phagocytic responsesof the hemocytes of R. ferrugineus and G. mellone…
