Intestinal cystic duplications are rare congenital anomalies, with an estimated incidence of approximately 1:4500 autopsies. The etiopathogenesis is uncertain. These duplications are cystic, tubular or diverticular structures lined with gastrointestinal mucosa. They share a common smooth muscle wall with the gastrointestinal tract but usually their lumens do not communicate with each other. Gastric duplication cysts represent 7-9% of the gastrointestinal tract duplication. They can be diagnosed prenatally by fetal ultrasound; magnetic resonance imaging characterizes the cyst and excludes other malformations...

Fever of unknown origin (FUO) is defined as fever over 7 to 10 days without a diagnosis despite a complete initial study. The most frequent causes are infections, autoimmune and tumors. Even though most cases are self-limited there is a minority that has an underlying etiology with an ominous forecast, encouraging a systematized study. OBJECTIVE: To report a rare case of a boy who presented fever of unknown origin associated to panniculitis and was diagnosed of subcutaneous panniculitis-like-T cell lymphoma and to emphasis the importance of a sequential study of FUO, in order to reach a diagnosis in patients who need a timely intervention...

BACKGROUND: An analysis of cardiac injury markers in patients with obstructive sleep apnea (OSA) who sustain an episode of acute coronary syndrome (ACS) may contribute to a better understanding of the interactions and impact of OSA in ACS subjects. We compared peak cardiac troponin-I (cTn-I) levels in patients admitted for ACS with and without OSA. METHODS: Blood samples were collected every 6 hours from the time of admission until 2 consecutive assays showed a downward trend in the cTn-I assay...

Several studies have observed that a conventional PCR protocol using primers LM1 and LM2 for the identification of gene hlyA Listeria monocytogenes generates non-specific PCR amplifications and false positives. For this reason in this study, we provide a modified PCR protocol that improves the specificity of the LM1 and LM2 primers.

Montserrat A de la Rosa Rodriguez, Sander Kersten
Excess fatty acids are stored in cells as triglycerides in specialized organelles called lipid droplets (LD). LD can be found in nearly all cell types and may expand during certain (patho)physiological conditions. The synthesis and breakdown of triglycerides and their deposition in LD is governed by a diverse set of enzymes and LD-associated proteins. These proteins serve structural roles in and around LD and regulate the activity of key lipogenic and lipolytic enzymes. The LD-associated proteins are subject to multiple regulatory mechanisms at the protein and gene expression level...

BACKGROUND AND AIMS: Type 2 diabetic patients have an increased proportion of electronegative low-density lipoprotein (LDL(-)), an inflammatory LDL subfraction present in blood, and dysfunctional high-density lipoprotein (HDL). We aimed at examining the inflammatory effect of LDL(-) on monocytes and the counteracting effect of HDL in the context of type 2 diabetes. METHODS: This was a cross-sectional study in which the population comprised 3 groups (n = 12 in each group): type 2 diabetic patients with good glycaemic control (GC-T2DM patients), type 2 diabetic patients with poor glycaemic control (PC-T2DM), and a control group...

The effects of adding two winery wastes, perlite waste (PW) and bentonite waste (BW), to an acid vineyard soil were assessed using some chemical and biological soil properties in a field study that lasted 18 months. The addition of PW (up to 81 Mg ha(-1)) had neither significant nor permanent effects on soil characteristics such as the pH, organic matter content or nutrient concentrations, the amounts of copper or zinc, or the electrical conductivity. Moreover, no persistent negative effects were found on the enzymatic activities after PW application...

The use of alkyl lead derivatives as antiknock agents in gasoline can be considered as one of the main pollution disasters of the 20th century because of both the global character of the pollution emitted and the seriousness of the impact on human health. Alkyl lead derivatives in themselves cannot be considered to be persistent pollutants because they readily degrade either before being released from the tailpipes or soon afterwards in the atmosphere. However, the inorganic lead they produced has been deposited in soils all over the planet, largely, but not exclusively in urban areas and along motorways, since the direct emission of lead into the atmosphere favored its dispersal over great distances: The signal of the massive use of alkyl lead derivatives has been found all over the world, including in remote sites such as polar areas...

Climate warming affects the development and distribution of sea ice, but at present the evidence of polar ecosystem feedbacks on climate through changes in the atmosphere is sparse. By means of synergistic atmospheric and oceanic measurements in the Southern Ocean near Antarctica, we present evidence that the microbiota of sea ice and sea ice-influenced ocean are a previously unknown significant source of atmospheric organic nitrogen, including low molecular weight alkyl-amines. Given the keystone role of nitrogen compounds in aerosol formation, growth and neutralization, our findings call for greater chemical and source diversity in the modelling efforts linking the marine ecosystem to aerosol-mediated climate effects in the Southern Ocean...

Human leishmaniasis are widely spread diseases with different clinical forms caused by about 20 species within the Leishmania genus. Leishmania species identification is relevant for therapeutic management and prognosis, especially for cutaneous and muco-cutaneous forms. Several methods are available to identify Leishmania species from culture, but they have not been standardized for the majority of the currently described species, with the exception of MultiLocus Enzyme Electrophoresis. Moreover, these techniques are expensive, time-consuming and not available in all laboratories...

The photoprocesses involved in the photo-induced Candida tropicalis biofilm reduction by two natural anthraquinones (AQs), rubiadin (1) and rubiadin-1-methyl ether (2), were examined. Production of singlet oxygen (1O2) and of superoxide radical anion (O2•-) was studied. Although it was not possible to detect the triplet state absorption of any AQs in biofilms, observation of 1O2 phosphorescence incubated with deuterated Phosphate Buffer Solution, indicated that this species is actually formed in biofilms...

Electron transfer in proteins is essential in crucial biological processes. Although the fundamental aspects of biological electron transfer are well characterized, currently there are no experimental tools to determine the atomic-scale electronic pathways in redox proteins, and thus to fully understand their outstanding efficiency and environmental adaptability. This knowledge is also required to design and optimize biomolecular electronic devices. In order to measure the local conductance of an electrode surface immersed in an electrolyte, this study builds upon the current-potential spectroscopic capacity of electrochemical scanning tunneling microscopy, by adding an alternating current modulation technique...

A 19-year-old woman with a history of isosexual precocious puberty and bilateral oophorectomy at age 10 years because of giant ovarian cysts, presents with headaches and mild symptoms and signs of hyperthyroidism. Hormonal evaluation revealed elevated FSH and LH levels in the postmenopausal range and free hyperthyroxinemia with an inappropriately normal TSH. Pituitary MRI showed a 2-cm macroadenoma with suprasellar extension. She underwent successful surgical resection of the pituitary tumor, which proved to be composed of two distinct populations of cells, each of them strongly immunoreactive for FSH and TSH, respectively...

Primary HIV-1 infection is a relevant period for its virological and epidemiological consequences. Most patients present a symptomatic disease that can be potentially serious, but neurological involvement during primary HIV-1 infection has been poorly studied. The aim of this study was to describe the characteristics and outcomes of primary HIV-1 infection patients presenting neurological symptoms and to compare them with primary HIV-1 infection patients without neurological involvement. Retrospective case-control study (1:3) comparing primary HIV-1 infection patients with and without neurological involvement enrolled in the Acute/Recent Hospital Clinic PHI Cohort between 1997 and 2016...

Oxygen availability drives changes in microbial diversity and biogeochemical cycling between the aerobic surface layer and the anaerobic core in nitrite-rich anoxic marine zones (AMZs), which constitute huge oxygen-depleted regions in the tropical oceans. The current paradigm is that primary production and nitrification within the oxic surface layer fuel anaerobic processes in the anoxic core of AMZs, where 30-50% of global marine nitrogen loss takes place. Here we demonstrate that oxygenic photosynthesis in the secondary chlorophyll maximum (SCM) releases significant amounts of O2 to the otherwise anoxic environment...
