Orchids have minute, air-filled seeds and are considered to be efficient dispersers and colonizers. However, empirical studies show that most seeds fall within a metre of the mother plant in orchids, and that individuals standing close to each other are often closely related. A poor contribution to gene dispersal by seeds may be compensated for by more efficient dispersal by pollen, but in autogam
Drawing upon the perspective of the cultural studies of emotions, this article examines the reception of political satire and the re-contextualization of humour. More precisely, it investigates the multiplicity of tensions that come into play in the production, erasure, rediscovery, and reception in BelarusianInternet media of politically oriented Russian television humour mocking the Belarusian p
Many studies have over the years utilized gravity models derived from trade theories to investigate how various factors affect trade in agricultural goods. Although technological improvements could be considered in such models, few studies have considered this topic in depth, leaving a void to fill. To partly fill this void, this study has chosen the silk sector to analyze the impact of technologi

Serum response factor (SRF) is a transcription factor that controls the expression of cytoskeletal proteins and immediate early genes in different cell types. Here, we found that SRF expression is restricted to endothelial cells (ECs) of small vessels such as capillaries in the mouse embryo. EC-specific Srf deletion led to aneurysms and hemorrhages from 11.5 days of mouse development (E11.5) and l
RhoH is a small GTPase expressed only in the hematopoietic system. With the use of mice with targeted disruption of the RhoH gene, we demonstrated that RhoH is crucial for thymocyte maturation during DN3 to DN4 transition and during positive selection. Furthermore, the differentiation and expansion of DN3 and DN4 thymocytes in vitro were severely impaired. These defects corresponded to defective T
This paper reports the interim results of an ongoing systematic review of the available evidence for the effectiveness of nursing care for people with Parkinson's disease (PD). Five clinical and four health-economic evaluations suggest that the clinical and cost effectiveness of nursing care for PD remain inconclusive. This is in contrast to clinical experience and may be due to issues related to
Background Transcriptional regulation of the genes in metabolic pathways is a highly successful strategy, which is virtually universal in microorganisms. The lac operon of E. coli is but one example of how enzyme and transporter production can be made conditional on the presence of a nutrient to catabolize. Methodology With a minimalist model of metabolism, cell growth and transcriptional regula
We prove that polynomial calculus (and hence also Nullstellensatz) over any field requires linear degree to refute that sparse random regular graphs, as well as sparse Erdős-Rényi random graphs, are 3-colourable.
Politics should be constituted by social representativeness in order to be conceptualised as democratic and legitimate. The set of politicians ought to be diverse and heterogeneous with the aim to include a wide spectrum of interest and concerns. The debate about women lacking power in politics was raised in the seventies. The political parties acted in response to the debate by implementing diffe
