Updates in the flora of the Maltese Islands (Central Mediterranean)
No full textDuring the last 5 years, this author has been involved in the research and exploration of the flora of the
Maltese islands in order to create and update the website http://www.maltawildplants.com. This paper
consists of several important discoveries of new populations of very rare or endangered floral species for
the Maltese Islands which were recorded during field surveys to collect material for this website. It also
includes the species Calendula bicolor Rafin., which is a new record for the Maltese islands.peer-reviewe
Flora Tristan Life Stories
No full textFlora Tristan is best known as a nineteenth century French social critic and reformer. Her writings can be seen as a precursor to Marxism and Feminism. Flora Tristan: Life Sories by Susan Grogan, investigates the life of Flora Tristan through an exploration of the way she represented herself in her own writings. The author also examines the portrayal of Flora Tristan in paintings and literature. Rather than adopting a chronological approach, the author surveys the personae of Flora Tristan through thematic chapters on her roles as author, socialist, traveller and "Mother of the Workers". She places Flora Tristan in the context of contemporary debates and ideas, adding to our understanding of the times in which Flora Tristan lived. Flora Tristan: Life Stories argues that Flora Tristan's self-representations were attempts to claim a role of authority and significance not open to women in the nineteenth century. This authoritative study also engages with attempts to re-evaluate the writing of biography and to explore the meaning of an individual life in historical context.Book Cover -- Title -- Copyright -- ContentsFlora Tristan is best known as a nineteenth century French social critic and reformer.

Role of microRNA in pancreatic beta cell function
No full textMicroRNA (miRNAs) are small non-coding RNA involved in gene expression regulation. Emerging evidences identify miRNAs as key regulators of beta cell physiology. Their role in fine-tuned gene expression regulation is crucial in the differentiation of insulin-producing cells and contributes to the acquisition and management of their unique phenotype. Dysregulation of miRNA expression causes beta cell dysfunction and promotes the development of different forms of diabetes mellitus
A comparison of the moss floras of Chile and New Zealand
No full textChile and New Zealand share a common stock of 181 species of mosses in 94 genera and 34 families. This number counts for 23.3% of the Chilean and 34.6% of the New Zealand moss flora. If only species with austral distribution are taken into account, the number is reduced to 113 species in common, which is 14.5% of the Chilean and 21.6% of the New Zealand moss flora. This correlation is interpreted in terms of long distance dispersal resp. the common phytogeographical background of both countries as parts of the palaoaustral floristic region and compared with disjunct moss floras of other continents as well as the presently available molecular data
Defining indigenous plants: some problematic species from Norfolk Island
No full textDefining indigenous species may at first appear straight forward; most botanical texts provide similar definitions. The consistent requirement of such definitions is the lack of human intervention in the occurrence of the species within the area under consideration. Islands around the world have been invaded by plant species brought to their shores by humans. They are also places where self-introduced species can be continually arriving, as they have done for millennia. Scrutiny of the situation on Norfolk Island (1200 km east of Australia) finds that the distinction between indigenous and introduced taxa is sometimes unclear. There is also inconsistency regarding the acceptance of self-introduced species as indigenous. This paper explores these issues and notes that they are more important than idle botanical curiosity, because control of introduced (weed) species is a major area of activity in managing protected natural areas
The microRNAs miR-211-5p and miR-204-5p modulate ER stress in human beta cells
No full textMicroRNAs (miRNAs) are a class of small non-coding RNAs that regulate gene expression. Type 1 diabetes is an autoimmune disease characterized by insulits (islets inflammation) and pancreatic beta cell destruction. The pro-inflammatory cytokines interleukin-1β (IL-1β) and interferon-γ (IFN-γ) are released during insulitis and trigger endoplasmic reticulum (ER) stress and expression of pro-apoptotic Bcl-2 proteins in beta cells, thus contributing to their death. The nature of miRNAs that regulate ER stress and beta cell apoptosis remains to be elucidated. We have performed a global miRNA expression profile on cytokine-treated human islets and observed a marked down-regulation of miR-211-5p. By real-time PCR and western blot analysis, we confirmed cytokine-induced changes in the expression of miR-211-5p and the closely related miR-204-5p and downstream ER-stress related genes in human beta cells. Blocking of endogenous miRNA-211-5p and miR-204-5p by the same inhibitor (it is not possible to block separately these two miRs) increased human beta cell apoptosis, as measured by Hoechst/Propidium Iodide staining and by determination of cleaved caspase-3 activation. Interestingly, miRs-211-5p and 204-5p regulate the expression of several ER stress markers downstream of PERK, particularly the pro-apoptotic transcription factor CHOP. Blocking CHOP expression by a specific siRNA partially prevented the increased apoptosis observed following miR-211-5p/miR-204-5p inhibition. These observations identify a novel crosstalk between miRNAs, ER stress and beta cell apoptosis in early type 1 diabetes
