The genus Microtus has high karyotypic diversity. The existence of notable differences in the length of its sex chromosomes contributes to this variation. Variations in size are attributed to the enlargement of their heterochromatin content, which is of such magnitude in some species that they are referred to as "giant sex chromosomes". Here, we perform an intra- and interspecific analysis of t...

While angiosperm clocks can be described as an intricate network of interlocked transcriptional feedback loops, clocks of green algae have been modelled as a loop of only two genes. To investigate the transition from a simple clock in algae to a complex one in angiosperms, we performed an inventory of circadian clock genes in bryophytes and charophytes. Additionally, we performed functional cha...

Abstract: Aim: To investigate chemo-preventive effect of methanolic fruit extract Cucumis melo var. agrestis on DEN (diethyl-nitrosamine) induced hepatocellular carcinoma in Sprague Dawley rats. Materials and Methods: Five groups rats randomly selected comprising 6 animals each group, all groups, except Group-1 were administered single dose (200 mg/kg, i.p. dissolved PBS) for the induction HCC ...

We show that the N = 2 open string describes a theory of self-dual Yang Mills (SDYM) in (2, 2) dimensions. The coupling to the closed sector is described by SDYM in a Kähler background, with the Yang-Mills fields providing a source term to the self-duality equation in the gravity sector. The four-point S-matrix elements of the theory vanish, so the tree-level unitarity constraints leading to th...

These paper deals with 45 taxa, seven of which are new to the Balearic Islands flora: Agrostis capillaris L., Centaurea solstitialis L. Chenopodium strictum Roth, Datura wrigthii Regel, Kickxia elatine (L.) Dumort. subsp. elatine, Ranunculus xatardii Lapeyr. and Senecio inaequidens DC. On the other hand, six taxa [Catananche caerulea L., Centaurea apula Lam., Filago micropodioides Lange, Legous...

Eight hundred and thirteen European rodents and shrews encompassing seven different species were screened for alphacoronaviruses using PCR detection. Novel alphacoronaviruses were detected in the species Rattus norvegicus, Microtus agrestis, Sorex araneus and Myodes glareolus. These, together with the recently described Lucheng virus found in China, form a distinct rodent/shrew-specific clade w...
