Under normal growth conditions, Balbiani ring granules constitute premessenger ribonucleoprotein (RNP) particles synthesized in two chromosomal puffs, Balbiani ring (BR) 1 and 2, in the larval salivary glands of Chironomus tentans. At least three genes encoding 75S RNA are present in these two BRs: one in BR1 and two in BR2 (BR2.1 and BR2.2). The complexity of BR granule 75S RNA was studied by ...
In this paper continuing our work started in [Br1]-[Br3] we prove the corona theorem for the algebra of bounded holomorphic functions defined on an unbranched covering of a Caratheodory hyperbolic Riemann surface of finite type.
We continue the study of the center problem for the ordinary differential equation v′ = ∑∞ i=1 ai(x)v i+1 started in [Br1]-[Br5]. In this paper we present the highlights of the algebraic theory of centers.
The movement of bipartite geminiviruses such as squash leaf curl virus (SqLCV) requires the cooperative interaction of two essential virus-encoded movement proteins, BR1 and BL1. While the viral coat protein AR1 is not essential for systemic infection, genetic studies demonstrate that its presence masks the defective phenotype of certain BR1 missense mutants, thus suggesting that coat protein d...
We have isolated three freshwater bacterial strains that demonstrate the ability to degrade Giardia intestinalis cysts. These strains have been identified by 16S rRNA sequencing and phylogenetic analysis as belonging to the Flavobacterium columnare clade of the Cytophaga-Flavobacterium group. While the cyst degradation mechanism is unclear, two different effects on the cysts were observed: non-...
Adenylyl cyclases (ACs) generate cAMP, a second messenger of utmost importance that regulates a vast array of biological processes in all kingdoms of life. However, almost nothing is known about how AC activity is regulated through protein degradation mediated by ubiquitination or other mechanisms. Here, we show that transcriptional regulator interacting with the PHD-bromodomain 1 (TRIP-Br1, Se...
UNLABELLED Stem cell-based regenerative medicine is one of the most intensively researched medical issues. Pre-clinical studies in a large-animal model, especially in swine or miniature pigs, are highly relevant to human applications. Mesenchymal stem cells (MSCs) have been isolated and expanded from different sources. OBJECTIVE This study aimed at isolating and characterizing, for the first ...
