Ester Sales, Juan Viruel, Concha Domingo, Luis Marqués
A pool of 200 traditional, landraces and modern elite and old cultivars of rice, mainly japonica varieties adapted to temperate regions, have been used to perform a genome wide association study to detect chromosome regions associated to low temperature germination (LTG) regulation using a panel of 1672 SNP markers. Phenotyping was performed by determining growth rates when seeds were germinated at 25° and 15°C in order to separate the germination vigorousness from cold tolerance effects. As expected, the ability to produce viable seedlings varied widely among rice cultivars and also depended greatly on temperature...

Plasma cells (PC) represent the heterogeneous final stage of the B cells (BC) differentiation process. To characterize the transition of BC into PC, transcriptomes from human naïve BC were compared to those of three functionally-different subsets of human in vivo-generated PC: i) tonsil PC, mainly consisting of early PC; ii) PC released to the blood after a potent booster-immunization (mostly cycling plasmablasts); and, iii) bone marrow CD138+ PC that represent highly mature PC and include the long-lived PC compartment...

In Argentina, Chaetophractus villosus has a wide distribution that overlaps with agricultural areas where soybean is the predominant crop. In such areas the pesticide Roundup Full II® (RU) is widely applied. The genotoxic effect of its active ingredient glyphosate (RU is 66.2% glyphosate) on the peripheral blood lymphocytes of C. villosus was tested over a range of concentrations (280, 420, 560, 1120 μmol/L). Culture medium without glyphosate served as negative control, while medium containing mitomycin C served as positive control...

Cutaneous eruptions are among the most common immune-related adverse events (irAEs) associated with anti-programmed cell death protein 1/programmed cell death ligand 1 therapy, and are often clinically and histologically characterized as lichenoid. Nonlichenoid patterns may also occur and are likely to be encountered by surgical pathologists, given the increasing clinical use of these agents. The purpose of this study is to describe the histopathologic features of nonlichenoid cutaneous irAEs from patients receiving anti-programmed cell death protein 1/programmed cell death ligand 1 therapies for a variety of underlying advanced malignancies...

Celia Chávez-Mendoza, Esteban Sánchez
As Mexico is located within Mesoamerica, it is considered the site where the bean plant originated and where it was domesticated. Beans have been an integral part of the Mexican diet for thousands of years. Within the country, there are a number of genotypes possessing highly diverse physical and chemical properties. This review describes the major bioactive compounds contained on the Mexican varieties of the common bean. A brief analysis is carried out regarding the benefits they have on health. The effect of seed coat color on the nutraceutical compounds content is distinguished, where black bean stands out because it is high content of anthocyanins, polyphenols and flavonoids such as quercetin...

Information on familial resemblance is important for the design of effective family-based interventions. We aimed to quantify familial correlations and estimate the proportion of variation attributable to genetic and shared environmental effects (i.e., familiality) for dietary intake variables and determine whether they vary by generation, sex, dietary quality, or by the age of the children. The study sample consisted of 1435 families (1007 mothers, 438 fathers, 1035 daughters, and 1080 sons) from the multi-center I...

OBJECTIVES: The ability to efficiently review the existing literature is essential for the rapid progress of research. This paper describes a classifier of text documents, represented as vectors in spaces of Wikipedia concepts, and analyses its suitability for classification of Spanish biomedical documents when only English documents are available for training. We propose the cross-language concept matching (CLCM) technique, which relies on Wikipedia interlanguage links to convert concept vectors from the Spanish to the English space...

It has been twenty years since diagnosis and publication of the species Homo antecessor.(1) Since then, new human fossils recovered from the TD6 level of the Gran Dolina site (Sierra de Atapuerca, northern Spain) have helped to refine its taxonomic and phylogenetic position. In this paper, we present a synthesis of the most characteristic features of this species, as well as our interpretation derived from the latest investigations. We focus on the phylogenetic interpretation of Homo antecessor, taking into account the most recent paleogenetic analyses and a reassessment of the European Middle Pleistocene hominin record...

REVIEW
Parham Khosravi-Shahi, Luis Cabezón-Gutiérrez, Sara Custodio-Cabello
Triple negative breast cancer (TNBC) is a heterogeneous disease, not only on the molecular level, but also on the pathologic and clinical levels. It also has a distinct epidemiology. TNBCs are frequently of high histologic grade, typically more aggressive and difficult to treat than hormone receptor-positive tumors, and they are associated with a higher risk of early relapse with visceral metastasis after surgery, chemotherapy and/or radiotherapy. The lack of estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2 expression precludes the use of targeted therapies in advanced stages, and the only approved systemic treatment option is chemotherapy with or without bevacizumab...

BACKGROUND: Childhood asthma is very prevalent and costs can be high, especially in severe disease. This study aimed to estimate the cost of asthma in Portuguese children and the variations by level of asthma control. METHODS: A nationwide, population- and prevalence-based cost-of-illness study with a societal perspective was conducted. We measured direct and indirect costs using a bottom-up approach and a human capital method, respectively, for 208 children (<18 years), from two national repositories...

Over the years, squamous cell carcinomas (SCC) that mimicked vascular lesions have been encompassed within different classifications and the underlying etiopathogenic mechanisms have been interpreted in different ways by different authors. Here, we present a case of SCC with pseudovascular areas in the right leg of a 96-year-old woman with chronic venous insufficiency. Histopathological examination closely resembled an angiosarcoma, but the immunohistochemical negativity for endothelial markers and the strong positivity for the pancytokeratin marker AE1/AE3 revealed the epithelial nature of the neoplasm...

AIMS: In response to concerns regarding resource expenditures required to fully implement the 2012 NIA-AA Sponsored Guidelines for the neuropathologic assessment of Alzheimer's disease (AD), we previously developed a sensitive and cost-reducing Condensed Protocol (CP) at the University of Washington (UW) Alzheimer's Disease Research Center (ADRC) that consolidated the recommended NIA-AA protocol into fewer cassettes requiring fewer immunohistochemical stains. The CP was not designed to replace NIA-AA protocols, but instead to make the NIA-AA criteria accessible to clinical and forensic neuropathology practices where resources limit full implementation of NIA-AA guidelines...

PURPOSE: Cryptococcal meningitis is a potentially fatal fungal infection associated with a significant attributable morbidity and mortality, especially among HIV/AIDS patients. The first-line therapy for the treatment of this clinical entity is the combinatory therapy of amphotericin B plus flucytosine. However, the high cost, toxic effects, and limited repertoire of effective antifungal drugs have led to the investigation of novel molecules. This is a prospective, double-blinded, and randomized study performed in a Mexican tertiary care center to evaluate the antifungal activity of sertraline in the treatment of cryptococcal meningitis in HIV patients...
