Minuaria kabylica (Pomel) Dvořáková, a species of the section Polymechana Mattf., is defined in terms of taxonomy and chorology. The taxa Minuartia verna subsp. kabylica (Pomel) Maire et Weiller (= Alsine kabylica Pomel) from Northern Africa, and M. grandiflora (C. Presl) Dvořáková from Sicily are taxonomically identical. The distribution of M. kabylica is limited to the Atlas mountain system in Northern Africa and to the mountains of northern Sicily. The seed coat of M. kabylica is documented by an SEM photograph.
The Japanese Hossô-monk Jôkei (1155-1213) is one of the better-known contemporaries of the famous Hônen (1133-1212), whose Pure Land School (Jôdo-shû) became so influential in medieval Japanese society. The Tôshôdaiji shaka-nenbutsu ganmon of Jôkei, however, is an interesting example for the often overlooked renaissance of the Japanese Vinaya School (Kairistu-shû) at that time. Being the second in a series of translations of important texts by Jôkei, the present article tries also to discuss this ganmon in the context of Jôkei´s thought.
One of the most abundant immunologic cell types in early decidua is the uterine natural killer (UNK) cell that despite the presence of cytoplasmic granules rich in perforin and granzymes does not degranulate in normal pregnancy. UNK cells are important producers of angiogenic factors that permit normal dilation of uterine arteries to provide increased blood flow for the growing feto-placental unit. Gram-negative bacteria lipopolysaccharide (LPS) administration can trigger an imbalance of pro-inflammatory and anti-inflammatory cytokines impairing the normal immune cells activity as well as uterine homeostasis. The present study aimed to evaluate by immunohistochemistry the reactivity of perforin and α-actin on UNK cell from LPStreated pregnant mice. For the first time, we demonstrate that LPS injection in pregnant mice causes α-actin down regulation, concomitantly with perforin loss in UNK cells. This suggests that LPS alters UNK cell migration and activates cytotoxic granule release., B. Zavan, A. M. do Amarante-Paffaro, V. A. Paffaro Jr., and Obsahuje bibliografii
The concept of α-ideals in posets is introduced. Several properties of α-ideals in 0-distributive posets are studied. Characterization of prime ideals to be α-ideals in 0- distributive posets is obtained in terms of minimality of ideals. Further, it is proved that if a prime ideal I of a 0-distributive poset is non-dense, then I is an α-ideal. Moreover, it is shown that the set of all α-ideals α Id(P) of a poset P with 0 forms a complete lattice. A result analogous to separation theorem for finite 0-distributive posets is obtained with respect to prime α-ideals. Some counterexamples are also given.
In vitro produced β-like cells can provide promising cell therapy for curing the epidemic of diabetes. In this context, we aimed to investigate the effects of different concentrations of γ-aminobutyric acid (GABA) on the differentiation of rat pancreatic ductal epithelial-like stem cells (PDESCs) into β-like cells. The PDESC line cells were cultured in the basal media (DMEM/F12 + 10% FBS + 1% penicillinstreptomycin) supplemented with 0 µM, 5 µM, 50 µM, 500 µM, and 5 mM of GABA for 28 days to induce their differentiation. The differentiated cells were detected by cell morphology, dithizone (DTZ) staining, immunofluorescence staining, real-time polymerase chain reaction (qPCR), and glucose-stimulated insulin secretion (GSIS) assay to validate their identity. At the end of 28 days, compared with the control group, enrichment of induced cells was high among the 5 μM, 50 μM, 500 μM, and 5 mM GABA induction groups. The formation of islet-like cell clusters (ICCs) began at 14 days, and the cell clusters showed a growth trend with the culture time. The induced ICCs were positive for DTZ staining, while the control group showed negative results for DTZ staining and the differentiated cells were also positive for β-cell-specific markers (Ins1 and Pdx1). GSIS assay of 50 μM induction group cells at 28 days showed significantly higher levels of C-peptide and insulin secretion than the control, 5 μM, 500 μM, and 5 mM GABA-treated groups (P < 0.01). At the same time, the 50 μM induction group cells also showed significantly higher levels of Ins1, Pdx1 and Nkx6.1 mRNA as compared to the 5 μM, 500 μM and 5 mM GABA groups (P < 0.01). Thus, the addition of GABA to the basal medium effectively induced differentiation of adult rat PDESCs into insulin-secreting β-like cells, and 50 μM was the most effective concentration for the induction.
\vspace{-1.6cm} The paper studies the relations between ϕ-divergences and fundamental concepts of decision theory such as sufficiency, Bayes sufficiency, and LeCam's deficiency. A new and considerably simplified approach is given to the spectral representation of ϕ-divergences already established in Österreicher and Feldman \cite{OestFeld} under restrictive conditions and in Liese and Vajda \cite{LiV06}, \cite{LiV08} in the general form. The simplification is achieved by a new integral representation of convex functions in terms of elementary convex functions which are strictly convex at one point only. Bayes sufficiency is characterized with the help of a binary model that consists of the joint distribution and the product of the marginal distributions of the observation and the parameter, respectively. LeCam's deficiency is expressed in terms of ϕ-divergences where ϕ belongs to a class of convex functions whose curvature measures are finite and satisfy a normalization condition.
The structuralistic point of view seems to be applicable in the sociolinguistics as far as the relation of language norms and varieties is concerned. Language norms can be classifiable as components of human consciousness, the function of which is to regulate language expectations and actions. These norms reflect social and language phenomena. Varieties are coherent collections of language elements which can be distributed according to geographic, social or functional criteria. The relation between norms and varieties is that between invariant and variant elements. These units facilitate to operationalize the sociolin-guistic perception of language-users. Invariant constructs with their sociolinguistic relevance (segments of norms) are realizable in various ways, which depends on various factors determining communicative situations. The author suggests to coin the term normeme for the realizable unit and allonorme for the realized variants (segments of varieties).
