Maf/ham1-like pyrophosphatases of non-canonical nucleotides are host-specific partners of viral RNA-dependent RNA polymerases.

Cassava brown streak disease (CBSD), dubbed the "Ebola of plants", is a serious threat to food security in Africa caused by two viruses of the family Potyviridae: cassava brown streak virus (CBSV) and Ugandan (U)CBSV. Intriguingly, U/CBSV, along with another member of this family and one secoviridae, are the only known RNA viruses encoding a protein of the Maf/ham1-like family, a group of widespread pyrophosphatase of non-canonical nucleotides (ITPase) expressed by all living organisms. Despite the socio-economic impact of CDSD, the relevance and role of this atypical viral factor has not been yet established.

Impact of COVID-19 in nutritional and functional status of survivors admitted in intensive care units during the first outbreak. Preliminary results of the NUTRICOVID study.

Background & Aims: COVID-19 patients present a high hospitalization rate with a high mortality risk for those requiring intensive care. When these patients have other comorbid conditions and older age, the risk for severe disease and poor outcomes after ICU admission are increased. The present work aims to describe the preliminary results of the ongoing NUTRICOVID study about the nutritional and functional status and the quality of life of adult COVID-19 survivors after ICU discharge, emphasizing the in-hospital and discharge situation of this population.

De novo small deletion affecting transcription start site of short isoform of AUTS2 gene in a patient with syndromic neurodevelopmental defects.

Disruption of the autism susceptibility candidate 2 (AUTS2) gene through genomic rearrangements, copy number variations (CNVs), and intragenic deletions and mutations, has been recurrently involved in syndromic forms of developmental delay and intellectual disability, known as AUTS2 syndrome. The AUTS2 gene plays an important role in regulation of neuronal migration, and when altered, associates with a variable phenotype from severely to mildly affected patients. The more severe phenotypes significantly correlate with the presence of defects affecting the C-terminus part of the gene.

In vivo chromatin remodeling events leading to inflammatory gene transcription under diabetic conditions.

The transcription factor NF-kappaB (NF-kappaB) plays a pivotal role in regulating inflammatory gene expression. Its effects are optimized by various coactivators including histone acetyltransferases (HATs) such as CBP/p300 and p/CAF. Evidence shows that high glucose (HG) conditions mimicking diabetes can activate the transcription of NF-kappaB-regulated inflammatory genes.

Working memory and relational reasoning in Klinefelter syndrome.

Klinefelter syndrome (KS) is a sex chromosome abnormality associated with male infertility and mild cognitive deficits. Individuals with KS have been reported to have impaired verbal ability, as well as deficits in executive function. To further understand the nature of their deficits, we assessed specific elements of frontal lobe function such as working memory and relational reasoning.

[18F]fluorodeoxyglucose triple-head coincidence imaging as an adjunct to 131I scanning for follow-up of papillary thyroid carcinoma.

Objective: To evaluate the feasibility of using [(18)F]fluorodeoxyglucose ((18)FDG) triple-head coincidence imaging as a potential cost-effective alternative to positron emission tomography in the setting of suspected recurrence of papillary thyroid carcinoma.

Methods: We retrospectively studied 10 patients with suspected recurrence of papillary carcinoma of the thyroid, who underwent (18)FDG coincidence imaging,(131)I scanning, and a reference anatomic scan (computed tomography, magnetic resonance imaging, or both) within 1 year in most cases.

Results: The (131)I scan detected the recurrence in five patients (62.
