Xylotrechus arvicola is an important pest in vineyards (Vitis vinifera) in the main Iberian wine-producing regions, and Acanthoscelides obtectus causes severe post-harvest losses in the common bean (Phaseolus vulgaris). Under laboratory conditions with a spray tower, the susceptibility of the immature stages of X. arvicola and A. obtectus against the entomopathogenic fungi Beauveria bassiana and four strains of Trichoderma spp. was evaluated. Both insect pests T. harzianum and B. bassiana showed a good inhibitory activity, accumulating an inhibition on the eggs of values above 85 and 82%, respectively...

Infection by Toxoplasma gondii affects around one-third of world population and the treatment for patients presenting toxoplasmosis clinically manifested disease is mainly based by a combination of sulfadiazine, pyrimethamine, and folinic acid. However, this therapeutic protocol is significantly toxic, causing relevant dose-related bone marrow damage. Thus, it is necessary to improve new approaches to investigate the usefulness of more effective and non-toxic agents for treatment of patients with toxoplasmosis...

BACKGROUND: Mutations in SCN2B, encoding voltage-gated sodium channel β2-subunits, are associated with human cardiac arrhythmias, including atrial fibrillation and Brugada syndrome. Because of this, we propose that β2-subunits play critical roles in the establishment or maintenance of normal cardiac electric activity in vivo. METHODS AND RESULTS: To understand the pathophysiological roles of β2 in the heart, we investigated the cardiac phenotype of Scn2b null mice...

Small cell lung cancer (SCLC) is a devastating disease due to its propensity for early invasion and refractory relapse after initial treatment response. Although these aggressive traits have been associated with phenotypic heterogeneity, our understanding of this association remains incomplete. To fill this knowledge gap, we inferred a set of 33 transcription factors (TF) associated with gene signatures of the known neuroendocrine/epithelial (NE) and non-neuroendocrine/mesenchymal-like (ML) SCLC phenotypes...

Psoriasis is a dermatologic disease of immune origins with no definitive cure. We report the Makati Medical Center experience of utilizing autologous mesenchymal stromal cells (MSCs) for one patient with psoriasis vulgaris (PV) and another with psoriatic arthritis (PA). Patients were educated and gave informed consent, according to the principles of the Declaration of Helsinki. The protocol was approved by the Cellular Transplantation Ethics Committee of the Makati Medical Center. Autologous MSCs were cultured from lipoaspirate and expanded in a clean room class 100 facility (Cellular Therapeutics Center, Makati Medical Center)...

BACKGROUND: The wide spread mosquito Culex pipiens pipiens have two forms molestus and pipiens which frequently hybridize. The two forms have behavioural and physiological differences affecting habitat requirements and host selection, which may affect the transmission dynamic of Cx. p. pipiens-borne diseases. METHODS: During 2013, blood engorged Cx. p. pipiens mosquitoes were captured in urban, rural and natural areas from Southern Spain. In 120 mosquitoes, we identified the blood meal origin at vertebrate species/genus level and the mosquito form...

Atypical hemolytic uremic syndrome (aHUS), a thrombotic microangiopathy (TMA), is a rare, life-threatening, systemic disease. When unrecognized or inappropriately treated, aHUS has a high degree of morbidity and mortality. aHUS results from chronic, uncontrolled activity of the alternative complement pathway, which activates platelets and damages the endothelium. Two-thirds of aHUS cases are associated with an identifiable complement-activating condition. aHUS is clinically very similar to the other major TMAs: Shiga toxin-producing Escherichia coli (STEC)-HUS, thrombotic thrombocytopenic purpura (TTP), and disseminated intravascular coagulation (DIC)...

Family educational involvement and parent-teacher relationships are important for supporting student outcomes and have unique implications for families of children with autism spectrum disorder (ASD). However, little research has examined child and family characteristics among families of children with ASD as predictors of family involvement and parent-teacher relationships. The present study examined child and family variables that may affect family involvement and parent-teacher relationships for families of children with ASD...

OBJECTIVE: Staff in pediatric intensive care units (PICU) are inherently exposed to potentially traumatic events. Posttraumatic growth (PTG) is the occurrence of positive changes after experiencing a traumatic event. This study aims (a) to evaluate the prevalence of PTG in PICU staff, and whether their scores are different from those reported by professionals working in other pediatric units, (b) to explore the role of resilience and coping strategies in predicting PTG, and (c) to explore the relation of demographic and work-related variables with PTG...

Leishmaniasis is a major public health problem worldwide. Because Leishmania can adapt to new hosts or vectors, knowledge concerning the current etiological agent in dogs is important in endemic areas. This study aimed to identify the Leishmania species detected in 103 samples of peripheral blood from dogs that were naturally infected with these protozoa. The diagnosis of leishmaniasis was determined through parasitological examination, the indirect enzyme-linked immunosorbent assay (ELISA) and the polymerase chain reaction (PCR)...

A pleiotropic response to the calpain inhibitor MDL28170 was detected in the tomato parasite Phytomonas serpens. Ultrastructural studies revealed that MDL28170 caused mitochondrial swelling, shortening of flagellum and disruption of trans Golgi network. This effect was correlated to the inhibition in processing of cruzipain-like molecules, which presented an increase in expression paralleled by decreased proteolytic activity. Concomitantly, a calcium-dependent cysteine peptidase was detected in the parasite extract, the activity of which was repressed by pre-incubation of parasites with MDL28170...

There is a reemergence of syphilis in the Latin American and Caribbean region. There is also very little information about HIV/Syphilis co-infection and its determinants. The aim of this study is to investigate knowledge, attitudes, and practices regarding sexually transmitted infections (STIs), in particular syphilis infection and HIV/Syphilis co-infection, as well as to estimate the prevalence of syphilis among men who have sex with men (MSM) in a city with one of the highest HIV prevalence rates in Ecuador...

Altered interplay between gut mucosa and dysbiotic bacteria during HIV infection seems to fuel chronic immune dysfunction and might explain the excess rates of HPV-associated anal cancer in HIV-infected individuals. Here, we show in HIV-infected MSM undergoing screening for HPV-related cancer that specific fecal and mucosal bacteria are able to predict the existence of precancerous anal lesions. If confirmed, these bacterial biomarkers could be exploited either as diagnostic tools or therapeutic targets.

Cell-free mitochondrial DNA (mtDNA) is a highly immunogenic molecule that is associated with several inflammatory conditions and with neurocognitive impairment during untreated HIV infection. Here, we investigate how cell-free mtDNA in cerebrospinal fluid (CSF) is associated with inflammation, neuronal damage, and neurocognitive functioning in the context of long-term suppressive antiretroviral therapy (ART). We quantified the levels of cell-free mtDNA in the CSF from 41 HIV-infected individuals with completely suppressed HIV RNA levels in blood plasma (<50 copies/mL) by droplet digital PCR...

We report the case of a 25-year-old male patient with tumor-induced osteomalacia from a 1.8-cm phosphaturic mesenchymal tumor in the right distal thigh, who was treated at our institution with a single session of CT-guided cryoablation in December 2015, which resulted in biochemical and clinical resolution. We present the clinical history, physical examination, biochemistry, functional imaging, anatomic characterization, and follow-up for clinical outcome. The response to treatment was documented in terms of normalization of serum fibroblastic growth factor 23 (FGF23) and phosphorous levels, symptomatic improvement, as well as normalization of bone mineralization on femur radiographs 3 months after the procedure...

As aberrant protein phosphorylation is a hallmark of tumor cells, the display of tumor-specific phosphopeptides by Human Leukocyte Antigen (HLA) class I molecules can be exploited in the treatment of cancer by T-cell-based immunotherapy. Yet, the characterization and prediction of HLA-I phospholigands is challenging as the molecular determinants of the presentation of such post-translationally modified peptides are not fully understood. Here, we employed a peptidomic workflow to identify 256 unique phosphorylated ligands associated with HLA-B*40, -B*27, -B*39 or -B*07...

AIMS: To understand how thyroid hormone (TH) regulates tissue-specific gene expression in patients with the syndrome of resistance to TH (RTHβ), we used a mouse model that replicates the human RTHβ, specifically the ∆337T mutation in the thyroid hormone receptor β (THRβ). MAIN METHODS: We investigated the expression of key TH target genes in the pituitary and liver of TRβ(∆337T) and wild type THRβ mice by qPCR before and after a T3 suppression test consisting of the administration of increasing concentrations of T3 to hypothyroid mice...
