- Language:

- Description:
- Our previous experiments revealed that water intoxication and osmotic BBB disruption in the rat allow penetration of high- molecular substances into the brain and that resulting changes in the internal environment of th e CNS lead to pathological development, such as the loss of integrity of myelin. The aim of the present study was to determine whether the previously described phenomena are associated with increased water content in the brain. To answer the question following methods were used: a) water intoxication : intraperitoneal administration of distilled water, b) osmotic BBB disruption: application of mannitol (20 %) selectively into the internal carotid artery, c) brain wet weight was measured after decapitation, and subsequently (after six days in thermostat set at 86 °C) the dry weight were estimated d) in animals with 20 % and 30 % hyperhydration the degree of myelin deterioration was estimated e) animal locomotor activity was tested by continuous behavior tracking and analysis. Brai n water content after water intoxication and following the administration of mannitol was higher than in the control group. Different degrees of hyperhydration led to different levels of brain water content and to different degrees of myelin impairment. Hyperhydration corresponding to 20 % of the body weight brought about lower locomotor activity. Increased water content in the brain after the BBB osmotic disruption is surprising because this method is frequently used in the clinical practice., P. Kozler, V. Riljak, J.

1934. Boundedness in a quasilinear parabolic-parabolic chemotaxis system with nonlinear logistic source

- Subject:
- matematika, mathematics, boundedness, chemotaxis, nonlinear logistic source, 13, and 51
- Language:
- English
- Description:
- We study a quasilinear parabolic-parabolic chemotaxis system with nonlinear logistic source, under homogeneous Neumann boundary conditions in a smooth bounded domain. By establishing proper a priori estimates we prove that, with both the diffusion function and the chemotaxis sensitivity function being positive, the corresponding initial boundary value problem admits a unique global classical solution which is uniformly bounded. The result of this paper is a generalization of that of Cao (2014)., Ji Liu, Jia-Shan Zheng., and Obsahuje seznam literatury

1935. Boundedness of para-product operators on spaces of homogeneous type

- Subject:
- matematika, mathematics, ohraničení, boundedness, Calderón-Zygmund singular integral operator, para-product, 13, and 51
- Language:
- English
- Description:
- We obtain the boundedness of Calderón-Zygmund singular integral operators T of non-convolution type on Hardy spaces Hp(X) for 1/(1 + ε) < p < 1, where X is a space of homogeneous type in the sense of Coifman and Weiss (1971), and ε is the regularity exponent of the kernel of the singular integral operator T. Our approach relies on the discrete Littlewood-Paley-Stein theory and discrete Calderón’s identity. The crucial feature of our proof is to avoid atomic decomposition and molecular theory in contrast to what was used in the literature., Yayuan Xiao., and Obsahuje bibliografii

1936. Bounds for the number of meeting edges in graph partitioning

- Description:
- Let $G$ be a weighted hypergraph with edges of size at most 2. Bollobás and Scott conjectured that $G$ admits a bipartition such that each vertex class meets edges of total weight at least $(w_1-\Delta_1)/2+2w_2/3$, where $w_i$ is the total weight of edges of size $i$ and $\Delta_1$ is the maximum weight of an edge of size 1. In this paper, for positive integer weighted hypergraph $G$ (i.e., multi-hypergraph), we show that there exists a bipartition of $G$ such that each vertex class meets edges of total weight at least $(w_0-1)/6+(w_1-\Delta_1)/3+2w_2/3$, where $w_0$ is the number of edges of size 1. This generalizes a result of Haslegrave. Based on this result, we show that every graph with $m$ edges, except for $K_2$ and $K_{1,3}$, admits a tripartition such that each vertex class meets at least $\lceil{2m}/5\rceil$ edges, which establishes a special case of a more general conjecture of Bollobás and Scott., Qinghou Zeng, Jianfeng Hou., and Obsahuje bibliografické odkazy

- Description:
- Jako Bouveretův syndrom je označována obstrukce v oblasti duodena impaktovaným žlučovým kamenem, který vycestuje cholecystoduodenální či cholecystogastrickou píštělí. Onemocnění je vzácné, vyskytuje se zejména u starších žen s četnými komorbiditami a vysokým operačním rizikem. K diagnóze se zpravidla dospěje endoskopicky nebo pomocí zobrazovacích metod. Pokud stav nelze řešit endoskopicky, je indikováno operační řešení. Autoři prezentují případ Bouveretova syndromu u 79leté pacientky, u níž se zdařilo zdokumentovat všechny fáze vyšetřovacího a léčebného procesu. Součástí sdělení je přehled literatury týkající se diagnostiky a terapie tohoto vzácného syndromu., Bouveret syndrome is a gastric outlet obstruction caused by impaction of a gallstone that passes through a cholecystoduodenal or cholecystogastric fistula. It is a rare disease, most common in elderly women with multiple comorbidities and high surgical risk. The diagnosis can be made either radiologically or endoscopically. Endoscopic extraction is the preferred therapeutic option. Surgical intervention is indicated when endoscopic methods fail. We describe a case of Bouveret syndrome in a 79 years old woman. The report is followed by a review of literature on the diagnostics and treatment of this rare syndrome., and P. Kocián, M. Bocková, J. Schwarz

- Description:
- Fourteen three-month-old rabbits spontaneously-infected with the microsporidium Encephalilozoon cuniculi Levaditi, Nicolau et Schoen, 1923 were inoculated intravenously with lymphocytes (Ly) from seropositive bovine leukemia virus infected cattle (Ly/BLV) or with fetal lamb kidney cells infected with bovine fetal leukemia (FLK/BLV). Thirteen rabbits were seropositive to BLV at least for a period of three months. Six rabbits died of pulmonary lesions. Chronic inflammatory lesions of ence-phalitozoonosis were found in six rabbits killed between 454 and 548 days of the observation period. Five animals bore subcutaneous granulomas. Immunohistochemically, E. cuniculi was demonstrated in the inflammatory lesions of rabbits studied. Control animals also spontaneously infected with E. cuniculi did not show clinical signs of encephalitozoonosis. Morphological changes were found incidentally in the form of small glial foci and focal interstitial nephritis in these animals. The combined action of BLV - E. cuniculi on the bodies of rabbits is proposed as a suitable model for the study of encephalitozoonosis in man with human immunodeficiency virus (HIV) infection.
