Parallel evolution of flower reduction in two alpineSoldanellaspecies (Primulaceae)

2014

The European endemic Soldanella has traditionally been divided into two morphologically well-defined sections. Section Tubiflores contains two species growing in high-elevation habitats, whereas most of the 14 species of section Soldanella inhabit montane forests. Section Tubiflores has a reduced floral morphology compared with section Soldanella. A previous phylogenetic study based on internal transcribed spacer (ITS) and AFLP data has revealed that, although the genus Soldanella itself is monophyletic, both sections are paraphyletic. Soldanella alpina (section Soldanella) forms a clade with S. minima and S. pusilla (section Tubiflores), and the grouping of S. alpina with S. pusilla has be…

Dental Pulp Polyps Contain Stem Cells Comparable to the Normal Dental Pulps

2013

Objectives: Few studies investigated the isolation of stem cells from pathologically injured dental tissues. The aim of this study was to assess the possibility of isolation of stem cells from pulp polyps (chronic hyperplastic pulpitis), a pathological tissue produced in an inflammatory proliferative response within a tooth. Study design: Pulp polyp tissues were enzymatically digested and the harvested single cells were cultured. Cultured cells underwent differentiation to adipocytes and osteoblasts as well as flowcytometric analysis for markers such as: CD90, CD73, CD105, CD45, and CD14. In addition we tried to compare other characteristics (including colonigenic efficacy, population doubl…

Public responses to intimate partner violence against women: the influence of perceived severity and personal responsibility.

2009

This paper explored public willingness to act when exposed to cases of intimate partner violence against women, by analyzing the influence of perceived severity and personal responsibility on two types of responses: mediating and reporting to the police. Results (N = 419) yielded main effects of personal responsibility for both types of responses. No main effects of perceived severity were found. A significant interaction between perceived severity and personal responsibility was found only for reporting responses. Results are discussed in light of the helping behavior research tradition. Implications for public education and advocacy programs are also considered. Marisol.lila@uv.es; Enriqu…

Math homework : Parental help and children’s academic outcomes

2019

In the present study, we examined the longitudinal relations between child-perceived parental help with math homework (i.e., support and control), children's math skills, and mother-reported task persistent behavior in homework situations. A total of 624 mother–child dyads were followed across Grade 6 and Grade 9, controlling for Grade 3 variables. At each measurement point, children completed math tests, and their mothers evaluated task persistence during homework. In Grades 6 and 9, children reported their perceptions of their parents’ help with math homework. First, the results showed that perceived support in Grade 6 predicted an increase in persistence during homework in Grade 9. Secon…

Vegetation of rock clefts and ledges in the Pamir Alai Mts, Tajikistan (Middle Asia)

2014

AbstractThe paper presents the results of phytosociological research conducted on the vegetation of rock clefts and ledges in the Pamir-Alai Mountains (Tajikistan, Middle Asia). During the field studies, done in 2010–2012, 101 phytosociological relevés were taken. Plant species were recorded according to the Braun-Blanquet cover-abundance scale. Communities of calcareous rock clefts and ledges with small soil amounts from several ranges (Zeravshan Mts, Hissar Mts, Hazratishokh Mts, Darvaz Mts, Rushan Mts and Vanch Mts), inhabiting mainly the alpine and subnival zone, have been described. A synopsis of the rock communities of the Pamir-Alai is proposed. In the examined vegetation plots 77 va…

DMPP and the adrenergic nerve terminal: mechanisms of noradrenaline release from vesicular and extravesicular compartments.

1977

DMPP (1,1-dimethyl-4-phenylpiperazine) in various concentrations between 1.6×10−6 M and 6.2×10−5 M was infused into isolated rabbit hearts to study the neuronal release and uptake of noradrenaline.

Prevention of the acute neurotoxic effects of phenytoin on rat peripheral nerve by H7, an inhibitor of protein kinase C.

1992

Abstract The neurotoxic effects of a single dose of phenytoin (150 mg/kg body weight) alone or 30 min after H7 (a protein kinase C inhibitor) injection (20 mg/kg body weight) were investigated in terms of peripheral neuromuscular function and Na + ,K + -ATPase activity of the sciatic nerve. This intraperitoneal injection of phenytoin induced complete blockade of muscle action potentials in the dorsal segmental muscles of the rat tail evoked by electric stimulation of the caudal nerve and a 40% decrease in the Na + ,K + -ATPase activity of the rat sciatic nerve when compared with control values, measured as the difference between total and ouabain-insensitive ATPase activity. Prior administr…
