Membrane architecture is crucially important for mitochondrial function and integrity. The MICOS complex is located at crista junctions and determines cristae membrane morphology and the formation of crista junctions. Here we provide data of the bona fide MICOS subunit MIC26 for determining cristae morphology. MiRNA-mediated downregulation of MIC26 results in higher protein levels of MIC27 and ...

New data on 10 adventive plant species are given. Two and one subspecies (Atriplex hortensis, Solanum nigrum subsp. schultesii, Nepeta cataria) new for the Republic of Buryatia. Five two interspecies hybrids (Arctium × mixtum, Galinsoga parviflora, Hesperis pycnotricha, Lactuca serriola, Medicago varia, Onobrychis viciifolia, Viola tricolor) recorded first time in Ulan-Ude city its neighborhood.

UNLABELLED INTRODUCTION The crista terminalis is a variant of normal anatomical structures within the right atrium that mimics an atrial mass on a transthoracic echocardiogram. Atrial septal aneurysm is a rare but well-recognized cardiac abnormality of uncertain clinical significance. The association between crista terminalis and atrial septal aneurysm is unusual but not completely casual. B...

In 2021, the author observed and collected Onobrychis caput-galli (L.) Lam., a species of Fabacee previously unknown to Portuguese vascular flora, according Checklist Flora (Sequeira et al., 2011). The was found in Algarve, very restricted area, with several sites occurrence, most which sharing similar habitat conditions. All evidence suggests that is native Portugal should be added flora.

Mitochondrial outer- and inner-membrane fusion events are coupled in vivo but separable and mechanistically distinct in vitro, indicating that separate fusion machines exist in each membrane. Outer-membrane fusion requires trans interactions of the dynamin-related GTPase Fzo1, GTP hydrolysis, and an intact inner-membrane proton gradient. Inner-membrane fusion also requires GTP hydrolysis but di...

To evaluate the role of perinodal tissue in the genesis of atrioventricular (AV) nodal reentry, echo beats were induced by programmed stimulation in nine superfused rabbit atrial-atrioventricular nodal preparations. In these preparations, extracellular bipolar electrograms were recorded simultaneously from the crista terminalis, interatrial septum arid His bundle, along with microelectrode acti...

genus onobrychis is an important forage crop consisting of approximately 130 annual and perennial species. the present research focused on the cytological studies of embryogenic (e) and non-embryogenic (ne) callus as well as root meristem cells of in vitro and in vivo grown plants. on the contrary to the previous studies, a diploid viciifolia variety with 2n= 2x= 16 chromosomes was observed for...
