REVIEW
María Morell, Nieves Varela, Concepción Marañón
Systemic autoimmune diseases (SADs) encompass a wide spectrum of clinical signs as a reflection of their complex physiopathology. A variety of mechanisms related with the innate immune system are in the origin of the loss of self-tolerance in these diseases, and for most of them, the myeloid leukocytes are key actors. Monocytes, macrophages, dendritic cells, and neutrophils are first-line immune effectors located in the interface between innate and adaptive immunity. They are crucial in the organization of the local and systemic responses to damage-associated molecular patterns (DAMPs) and determine the intensity, orientation, and duration of the local immune response through the expression of chemokines, costimulatory or protolerogenic factors...

Vitamin D synthesis takes place in the skin due to solar ultraviolet-B (UVB) radiation. Several studies have shown the association between low sun exposure, non-melanoma skin cancer (NMSC) and a lack of vitamin D synthesis. Since such synthesis in the body depends on the exposure of the skin to solar UVB radiation (290-320 nm), experimental measurements of this type of solar radiation are important. Tarapaca University in Arica, Chile, established a solar UV radiation laboratory in 2006 and since then this laboratory has performed systematic experimental solar UVB measurements using a calibrated biometer instrument...

The determination of faecal bile patterns offers new opportunities in the search for non-invasive biomarkers of disease status. The objective of this study was to describe the shifts in faecal bile acid (BA) composition induced by feeding a high-cholesterol/cholic acid diet (HC) over 7 weeks of experimental feeding in Wistar rats, and to evaluate the effect of onion included as a functional ingredient (HCO). A HPLC-MS/MS method allowed the detection of 29 bile acids, 10 of which were tentatively identified and 12 confirmed and quantified by means of standards and calibration curves...

OBJECTIVE: The functional PTPN22 R620W polymorphism (rs2476601) is clearly associated with susceptibility to several autoimmune diseases (ADs). However, the PTPN22 R263Q polymorphism (rs33996649) has been scarcely explored in different ADs. Here we aimed to examine the associations of the PTPN22 R620W and R263Q polymorphisms with susceptibility to or protection against rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and Graves' disease (GD) among Mexican patients. METHODS: We conducted a case-control study including 876 patients (405 with SLE, 388 with RA, and 83 with GD) and 336 healthy control individuals...

Alcohol use disorders (AUD) are 2 times higher among psychiatric patients than in the general population. The under-recognition of this dual diagnosis can entail several negative outcomes. Early assessment with a screening tool like the CAGE questionnaire could be an opportunity to improve patients' prognoses. The objective of this study is to assess AUD risk in an outpatient psychiatric sample with a modified CAGE, considering the influence of age, gender and clinical psychiatric diagnosis. An observational, multicentric, descriptive study was carried out...

Leptospirosis disease is caused by the spirochete Leptospira. It is a worldwide distribution zoonosis, with predominance in the tropics. In Spain, it is not frequent but some cases have been noticed especially in humid areas surrounded by rivers, lakes or ponds, such as Catalonia, Andalucia or the Valencian Community. It is transmitted by a variety of animals such as cows or rats, that are infected either by direct contact with these animals or their urine, or indirectly by consuming or being in contact with water contaminated by their urine...

Angiosarcoma (AS) is a malignant mesenchymal neoplasm of endothelial origin with a predominantly lymphatic immunophenotype, which accounts for less than 1% of all sarcomas. Cutaneous AS of the scalp is associated with high rates of local recurrence and a poor prognosis. Histologically, poorly differentiated AS often comprises solid epithelioid cells, although rare variants involving spindle cells have been reported; diagnosis requires immunohistochemical analysis using vascular cell markers. We report on a cutaneous spindle-cell AS of the scalp in a female patient; key features included spontaneous regression after biopsy, local recurrence 2 years later, and aberrant nuclear staining for S100 protein in an area of the tumor not expressing CD34 or D2-40...

In areas lacking potable water treatment, drinking contaminated water may represent a public health threat. In addition to enteropathogenic bacteria and parasites, fecal contamination in water environments is associated with the transmission of enteric viruses and other causal agents of infectious disease. Rotavirus and norovirus are the main enteric viral agents responsible for diarrheic outbreaks. The aim of the present study was to detect seasonal variation of rotavirus and norovirus in the surface water at Bassaseachic Falls National Park during 2013...

CpG islands (CGIs) are primarily promoter-associated genomic regions and are mostly unmethylated within highly methylated mammalian genomes. The mechanisms by which CGIs are protected from de novo methylation remain elusive. Here we show that insertion of CpG-free DNA into targeted CGIs induces de novo methylation of the entire CGI in human pluripotent stem cells (PSCs). The methylation status is stably maintained even after CpG-free DNA removal, extensive passaging, and differentiation. By targeting the DNA mismatch repair gene MLH1 CGI, we could generate a PSC model of a cancer-related epimutation...

The first cinchona-alkaloid-organocatalyzed enantioselective synthesis of chiral 1,4-dihydropyridine derivatives is described. Bis-cinchona catalyst 3b activates the Michael addition reaction between malononitrile derivatives 2 and enamines 1, affording the appealing and highly substituted 1,4-dihydropyridines 4 with very good results in most cases. This is one of very few examples of the synthesis of chiral 1,4-dihydropyridines by an enantioselective catalytic procedure. The highly substituted final compounds are of interest for their potential biological activity...

BACKGROUND: We hypothesized that patients undergoing surgery for colorectal cancer (CRC) with COPD as a comorbidity would consume more resources and have worse in-hospital outcomes than similar patients without COPD. Therefore, we compared different aspects of the care process and short-term outcomes in patients undergoing surgery for CRC, with and without COPD. METHODS: This was a prospective study and it included patients from 22 hospitals located in Spain - 472 patients with COPD and 2,276 patients without COPD undergoing surgery for CRC...

Plant pathogens are a serious threat to agriculture and to global food security, causing diverse crop diseases which lead to extensive annual yield losses. Production of effector proteins by pathogens, to manipulate host cellular processes, is central to their success. An understanding of fundamental effector biology is key to addressing the threat posed by these pathogens. Recent advances in 'omics' technologies have facilitated high-throughput identification of putative effector proteins, while evolving cellular, structural and biochemical approaches have assisted in characterising their function...

Phylogenetic relationships among seed plant taxa, especially within the gymnosperms, remain contested. In contrast to angiosperms, for which several genomic, transcriptomic and phylogenetic resources are available, there are few, if any, molecular markers that allow broad comparisons among gymnosperm species. With few gymnosperm genomes available, recently obtained transcriptomes in gymnosperms are a great addition to identifying single-copy gene families as molecular markers for phylogenomic analysis in seed plants...
