Systematic study and uncertainty evaluation of P, T-odd molecular enhancement factors in BaF

A measurement of the magnitude of the electric dipole moment of the electron (eEDM) larger than that predicted by the Standard Model (SM) of particle physics is expected to have a huge impact on the search for physics beyond the SM. Polar diatomic molecules containing heavy elements experience enhanced sensitivity to parity (P) and time-reversal (T)-violating phenomena, such as the eEDM and the scalar-pseudoscalar (S-PS) interaction between the nucleons and the electrons, and are thus promising candidates for measurements. The NL-eEDM collaboration is preparing an experiment to measure the eEDM and S-PS interaction in a slow beam of cold BaF molecules [P. Aggarwal et al., Eur. Phys. J. D 72, 197 (2018)]. Accurate knowledge of the electronic structure parameters, Wd and Ws, connecting the eEDM and the S-PS interaction to the measurable energy shifts is crucial for the interpretation of these measurements. In this work, we use the finite field relativistic coupled cluster approach to calculate the Wd and Ws parameters in the ground state of the BaF molecule. Special attention was paid to providing a reliable theoretical uncertainty estimate based on investigations of the basis set, electron correlation, relativistic effects, and geometry. Our recommended values of the two parameters, including conservative uncertainty estimates, are 3.13 ±0.12×1024Hzecm for Wd and 8.29 ± 0.12 kHz for W

Tempo and Mode of Genome Evolution in the Budding Yeast Subphylum

Budding yeasts (subphylum Saccharomycotina) are found in every biome and are as genetically diverse as plants or animals. To understand budding yeast evolution, we analyzed the genomes of 332 yeast species, including 220 newly sequenced ones, which represent nearly one-third of all known budding yeast diversity. Here, we establish a robust genus-level phylogeny comprising 12 major clades, infer the timescale of diversification from the Devonian period to the present, quantify horizontal gene transfer (HGT), and reconstruct the evolution of 45 metabolic traits and the metabolic toolkit of the budding yeast common ancestor (BYCA). We infer that BYCA was metabolically complex and chronicle the tempo and mode of genomic and phenotypic evolution across the subphylum, which is characterized by very low HGT levels and widespread losses of traits and the genes that control them. More generally, our results argue that reductive evolution is a major mode of evolutionary diversification.Fil: Shen, Xing-Xing. Vanderbilt University; Estados UnidosFil: Opulente, Dana A..

Intoxicação espontânea por Ipomoea carnea subsp. fistulosa (Convolvulaceae) em bovinos no Pantanal Matogrossense Spontaneous Ipomoea carnea subsp. fistulosa (Convolvulaceae) poisoning of cattle in the Brazilian Pantanal

Relata-se a intoxicação espontânea por Ipomoea carnea subsp. fistulosa (canudo, algodoeiro) em bovinos no Pantanal Matogrossense. As investigações iniciaram após a morte de 12 bovinos, de um rebanho de 500 animais, criados em uma extensa área intensamente infestada por I. carnea subsp. fistulosa com escassa disponibilidade de outra forragem. As mortes ocorreram entres os meses de junho e setembro de 2006. O quadro clínico foi caracterizado por emagrecimento e sinais neurológicos com dificuldade locomotora. Um bovino foi necropsiado sem que se observassem alterações macroscópicas significativas. Histologicamente havia tumefação e vacuolização celular, em neurônios, células acinares pancreáticas, tubulares renais e foliculares da tireóide. Bovinos com quadro clínico similar foram retirados da área invadida por I. carnea subsp. fistulosa e colocadas em áreas com pastagem nativa e de Brachiaria sp. e apresentaram melhora clínica após período de 15 dias.<br>A spontaneous Ipomoea carnea subsp. fistulosa (canudo, algodoeiro) poisoning of cattle in the county of Poconé, Brazilian Pantanal, is reported. The investigation began after 12 cattle had died from a flock of 500 animals maintained in an extensive area intensely infested by I. carnea subsp. fistulosa with scarce availability of other fodder plants. The deaths occurred from June to September of 2006. Clinical signs were loss of weight and neurological deficits with hypermetry and incoordination. No significant gross lesions were observed at postmortem examination of one bovine. Histological changes comprised widespread cytoplasmic vacuolation of neurons, cells of the thyroid, kidney and pancreas. Cattle with similar clinical picture, that had been removed from the area invaded by I. carnea subsp. fistulosa and placed into areas with native and Brachiaria sp. pasture, recovered clinically within 15 days

Fourth report on chicken genes and chromosomes 2022

The chicken continues to hold its position as a leading model organism within many areas of research, as well as a being major source of protein for human consumption. The First Report on Chicken Genes and Chromosomes [Schmid et al., 2000], which was published in 2000, was the brainchild of the late, and sadly missed, Prof Michael Schmid of the University of Würzburg. It was a publication bringing together updates on the latest research and resources in chicken genomics and cytogenetics. The success of this First report led to the subsequent publication of the Second [Schmid et al., 2005] and Third [Schmid et al., 2015] reports proving popular references for the research community. It is now our pleasure to be able to introduce publication of the Fourth report. Being seven years since the last report, this publication captures the many advances that have taken place during that time. This includes presentation of the detailed genomic resources that are now available, largely due to increasing capabilities of sequencing technologies and which herald the pangenomic age, allowing for a much richer and more complete knowledge of the avian genome. Ongoing cytogenetic work also allows for examination of chromosomes, specific elements within chromosomes and the evolutionary history and comparison of karyotypes. We also examine chicken research efforts with a much more ‘global’ outlook with a greater impact on food security and the impact of climate change, and highlight the efforts of international consortia, such as the Chicken Diversity Consortium. We dedicate this Report to Michael

Emergence of a Complex Relationship between HIV-1 and the microRNA Pathway

Recent experimental evidences support the existence of an increasingly complex and multifaceted interaction between viruses and the microRNA-guided RNA silencing machinery of human cells. The discovery of small interfering RNAs (siRNAs), which are designed to mediate cleavage of specific messenger RNAs (mRNAs), prompted virologists to establish therapeutic strategies based on siRNAs with the aim to suppress replication of several viruses, including human immunodeficiency virus type 1 (HIV-1). It has been appreciated only recently that viral RNAs can also be processed endogenously by the microRNA-generating enzyme Dicer or recognized by cellular miRNAs, in processes that could be viewed as an adapted antiviral defense mechanism. Known to repress mRNA translation through recognition of specific binding sites usually located in their 3′ untranslated region, miRNAs of host or viral origin may exert regulatory effects towards host and/or viral genes and influence viral replication and/or the host response to viral infection. This article summarizes our current state of knowledge on the relationship between HIV-1 and miRNA-guided RNA silencing, and discusses the different aspects of their interaction
