The peculiarities of genetic structure of the Blumeria graminis f. sp. hordei population in Lithuania

2014

In 2010, samples of Blumeria graminis f. sp. hordei both in sporulation and cleistothecia were collected in Lithuania from spring barley variety ‘Dina’. Eighty monopustule isolates were tested on differentials with well-known resistance genes. Frequencies of virulence genes, virulence complexity and pathotypes were detected. Virulence frequencies showed a wide range from 0 to 90%. The clear tendency of virulence increasing for Vla in cleistothecia was observed during the growing season of the pathogen. No virulences were found against resistances, which were present in the line SI1, as well as no matching virulence was found for the resistance gene mlo in Lithuania in 2010. Wide diversity o…

Growth and production of three macrozoobenthic species in the Gulf of Riga, including comparisons with other areas

1999

Three soft-bottom stations in the southern part of the Gulf of Riga were studied during the period December 1993 to January 1995. The amphipods, Monoporeia affinis and Pontoporeia femorata, and the poychaete Marenzelleria viridis, were analysed for production, using the cohort growth method. Animals were also analysed for carbon and nitrogen content in a CHN-analyser. Based on size measurements, the quantitative data were divided into age-classes and the growth of each cohort was calculated first as wet weight and then converted into carbon and nitrogen content. Total annual production of each species was calculated as well as turnover ratios. The turnover ratio for Monoporeia affinis was e…

Distribution, frequency and diversity of Bacillus thuringiensis in olive tree environments in Spain

1997

Summary Bacillus thuringiensis was isolated from samples collected from olive tree related habitats (olive groves, olive storage facilities and oil mills) of different olive producing regions in Spain. This bacterium was found in a high percentage (92%) of samples. From 72 samples analysed, 2244 sporulating colonies were selected and observed under phase contrast microscopy. From these, 414 colonies (18%) were classified as B. thuringiensis based on the production of parasporal crystals. A great variability of spore, crystal size and morphology was observed. The results indicate that olive groves are as rich as soil olive mills and olive storage facilities regarding the B. thuringiensis pop…

Generation of homozygosity and genome fixation in pea (Pisum sativum L.)

2013

Pea cultivars are nearly homozygous and thus homogeneous when they are released. The traditional method of selfing is slow and inefficient, taking up to ten generations of inbreeding following a cross to achieve a high level of homozygosity. Current single-seed-descent (SSD) methodologies enable a maximum of three generations per year to be developed in pea. Doubled haploidy and an in vitro based modified SSD technology have been utilised in many important crops for the rapid achievement of homozygosity, and thus acceleration of the breeding process. In pea, due to the lack of robust protocols, none of these technologies is routinely used in a breeding program. The aim of this study was to …

External, emotional and restrained eating in normal- and overweight French children: do parents and children agree?

2016

The Dutch Eating Behaviour Questionnaire for Children (DEBQ-C; van Strien & Oosterveld, 2008) was developed to assess external eating (EXT), emotional eating (EMO), and restriction (RES) in 7- to 12-years-old. The aim of this study was to compare children and parents' views of children's eating behaviour according to children's weight status in a sample of French participants. Children were asked about their own eating behaviour and parents were asked about their children's eating behaviour using the DEBQ-C in the child- and parent-report forms, respectively. One hundred and thirty families participated (n=55 overweight children, ow; n=75 normal-weight children, nw; children were weighted a…

Mini-Review: Two Brothers in Crime – The Interplay of TRESK and TREK in Human Diseases

2021

Abstract TWIK-related spinal cord potassium (TRESK) and TWIK-related potassium (TREK) channels are both subfamilies of the two-pore domain potassium (K2P) channel group. Despite major structural, pharmacological, as well as biophysical differences, emerging data suggest that channels of these two subfamilies are functionally more closely related than previously assumed. Recent studies, for instance, indicate an assembling of TRESK and TREK subunits, leading to the formation of heterodimeric channels with different functional properties compared to homodimeric ones. Formation of tandems consisting of TRESK and TREK subunits might thus multiply the functional diversity of both TRESK and TREK …

Prognostic factors for non-asphyxia-related cardiac arrest patients undergoing extracorporeal rewarming - HELP Registry Study

2020

Objective: Extracorporeal rewarming is the treatment of choice for patients who had hypothermic cardiac arrest, allowing for best neurologic outcome. The authors’ goal was to identify factors associated with survival in nonasphyxia-related hypothermic cardiac arrest patients undergoing extracorporeal rewarming. Design: All 38 cardiac surgery departments in Poland were encouraged to report consecutive hypothermic cardiac arrest patients treated with extracorporeal life support. All variables collected were analyzed in order to compare survivor and nonsurvivor groups. The parameters available at the initiation of extracorporeal rewarming were considered as potential predictors of survival in …

CONVERSIONS DE FREQUENCE ULTRA LARGE BANDE PAR MELANGE A QUATRE ONDES INTERMODAL EN CASCADE DANS LES FIBRES MULTIMODES

2017

International audience; Nous mettons en évidence des effets de conversion spectrale paramétrique avec des décalages spectraux très importants (~200THz) dans une fibre à gradient d'indice qui, pompée avec une source laser picoseconde à 1064nm, supporte quatre modes de propagation. À travers des études expérimentales, analytiques et numériques détaillées, nous montrons que les multiples raies paramétriques sont générées par un processus en cascade complexe faisant intervenir des mélanges à quatre ondes intermodaux. Les longueurs d'onde paramétriques résultantes s'étendent dans le visible jusqu'à 410nm et dans le proche infrarouge jusqu'à 1355nm. MOTS-CLEFS : dynamique spatio-temporelle ; conv…

Characterisation of Pythium paroecandrum and its antagonism towards Botrytis cinerea, the causative agent of grey mould disease of grape.

2004

Pythium paroecandrum (B-30), an oomycete, was isolated from soil samples taken from a wheat field in Genlis in the Burgundy region of France and was found to check the growth and development of Botrytis cinerea, a serious grapevine pathogen. The oomycete is a fast-growing organism, living on vegetable debris, and can be recognised by its catenulate hyphal swellings, catenulate oogonia, and monoclinous antheridia. When grown together with B. cinerea, the causal agent of the grey mould disease of the grapevine, P. paroecandrum shows a pronounced antagonism and suppresses its growth and its aptitude to provoke the grey mould symptoms. Morphological features of this oomycete, its antagonism to …
