Persistent infections with High Risk Human Papillomaviruses (HR-HPVs) are the main cause of cervical cancer development. The E6 and E7 oncoproteins of HR-HPVs are derived from a polycistronic pre-mRNA transcribed from an HPV early promoter. Through alternative splicing, this pre-mRNA produces a variety of E6 spliced transcripts termed E6*. In pre-malignant lesions and HPV-related cancers, different E6/E6* transcriptional patterns have been found, although they have not been clearly associated to cancer development...

The tumor suppressor FBW7 targets oncoproteins such as c-MYC for ubiquitylation and is mutated in several human cancers. We noted that in a significant percentage of colon cancers, FBW7 protein is undetectable despite the presence of FBW7 mRNA. To understand the molecular mechanism of FBW7 regulation in these cancers, we employed proteomics and identified the deubiquitinase USP9X as an FBW7 interactor. USP9X antagonised FBW7 ubiquitylation, and Usp9x deletion caused Fbw7 destabilization. Mice lacking Usp9x in the gut showed reduced secretory cell differentiation and increased progenitor proliferation, phenocopying Fbw7 loss...

BACKGROUND: Chronic total occlusion (CTO) of a coronary artery is defined as an occluded segment with no antegrade flow and a known or estimated duration of at least 12 weeks. OBJECTIVE: We considered the current literature describing the indications and clinical outcomes for de-novo CTO- percutaneous coronary intervention (PCI), and discuss the role of CTO-PCI and future directions for this procedure. METHOD: Databases (PubMed, the Cochrane Library, Embase, EBSCO, Web of Science, and CINAHL were searched and relevant studies of CTO-PCI were selected for review...

The study of airborne metals in urban areas is relevant due to their toxic effects on human health and organisms. In this study, we analyzed metals including rare earth elements (REE) in particles smaller than 2.5 μm (PM2.5), collected at five sites around the Mexico City Metropolitan Area (MCMA), during three periods in 2011: April (dry-warm season, DW), August (rainy season, R), and November (dry-cold season, DC). Principal component analysis allowed identifying factors related to geogenic sources and factors related to anthropogenic sources...

We report a biomarker-based non-endoscopic method for detecting Barrett's esophagus (BE) based on detecting methylated DNAs retrieved via a swallowable balloon-based esophageal sampling device. BE is the precursor of, and a major recognized risk factor for, developing esophageal adenocarcinoma. Endoscopy, the current standard for BE detection, is not cost-effective for population screening. We performed genome-wide screening to ascertain regions targeted for recurrent aberrant cytosine methylation in BE, identifying high-frequency methylation within the CCNA1 locus...

Progression of HIV infection is variable among individuals, and definition disease progression biomarkers is still needed. Here, we aimed to categorize the predictive potential of several variables using feature selection methods and decision trees. A total of seventy-five treatment-naïve subjects were enrolled during acute/early HIV infection. CD4⁺ T-cell counts (CD4TC) and viral load (VL) levels were determined at enrollment and for one year. Immune activation, HIV-specific immune response, Human Leukocyte Antigen (HLA) and C-C chemokine receptor type 5 (CCR5) genotypes, and plasma levels of 39 cytokines were determined...

Bottle-brush polymers exhibit closely grafted side chains that interact by steric repulsion, thereby causing stiffening of the main polymer chain. We use single-molecule elasticity measurements of model brush polymers to quantify this effect. We find that stiffening is only significant on long length scales, with the main chain retaining flexibility on short scales. From the elasticity data, we extract an estimate of the internal tension generated by side-chain repulsion; this estimate is consistent with the predictions of blob-based scaling theories...

Nanopesticides are novel plant protection products offering numerous benefits. As nanoparticles behave differently from dissolved chemicals, environmental risks of these materials could differ from conventional pesticides. Here we used soil-earthworm systems to compare the fate and uptake of analytical grade bifenthrin to that of bifenthrin in traditional and nano-encapsulated formulations. Apparent sorption coefficients for bifenthrin in the nano-treatments were up to 3.8 times lower than in the non-nano treatments whereas dissipation half-lives of the nano-treatments were up to two time longer...

We present what we believe to be the second case of pediatric penile porokeratosis and the youngest case reported. A 6-year-old boy presented with a pruritic, verrucous growth at the urethral meatus that recurred after two meatotomies. The diagnosis of porokeratosis was confirmed by biopsy. Porokeratosis should be added to the differential diagnosis of chronic hyperkeratotic penile lesions in children.

About ten years after their introduction to the market (happened in 2006), the so-called second generation superficially porous particles (SPPs) have undoubtedly become the benchmark as well as, very often, the preferred choice for many applications in liquid chromatography (LC), when high efficiency and fast separations are required. This trend has interested practically all kinds of separations, with the only exception of chiral chromatography (at least so far). The technology of production of base SPPs is advanced, relatively simple and widely available...

Although histoplasmosis is generally a self-limited disease, disseminated infection can occur in patients lacking effective cell-mediated immunity, reaching virtually every organ, even the genitourinary tract in rare cases. We report a case of epididymo-orchitis in an immunocompetent 38-year-old bricklayer from the rural area of Villeta, Cundinamarca, Colombia. The patient presented with testicular pain and macroscopic scrotal changes requiring a left orchiectomy, with microbiological isolation and molecular confirmation of Histoplasma capsulatum...

The World Health Organization and the American Psychological Association consider transsexuality a pathology and suggest sex-gender reassignment for the biopsychic adjustment of trans people. Through the discursive analysis of experience, this study describes the processes of medicalization and gender performativity in relation to the health of a group of trans women from Mexico City. For this purpose, a qualitative study was conducted in which 10 semi-structured interviews were carried out in 2015. As part of medicalization, the pathologization of transsexuality generated psychic suffering; on the other hand, sex-gender reassignment also entailed additional risks...

Nonadherence to treatment, and its associated health and economic burden, is particularly problematic in asthma and chronic obstructive pulmonary disease management because of heterogeneous patient populations and the need for an inhaled route of drug administration. Symptom variability, comorbidities, and device switching further add to suboptimal adherence rates. As opposed to controlled clinical trials, real-life studies show consistently low inhaler adherence in daily practice, yet exact adherence rates have long been affected by disagreement on standardized definitions...

BACKGROUND: Inhaled drug delivery is the cornerstone treatment for asthma and chronic obstructive pulmonary disease (COPD). However, use of inhaler devices can be challenging, potentially leading to critical errors in handling that can significantly reduce drug delivery to the lungs and effectiveness of treatment. METHODS: A systematic review was conducted to define 'critical' errors and their impact on health outcomes and resource use between 2004 and 2016, using key search terms for inhaler errors in asthma and COPD (Search-1) and associated health-economic and patient burden (Search-2)...

BACKGROUND: Mesenchymal stromal cells (MSC) are a heterogeneous population of multipotent progenitors used in the clinic because of their immunomodulatory properties and their ability to differentiate into multiple mesodermal lineages. Although bone marrow (BM) remains the most common MSC source, cord blood (CB) can be collected noninvasively and without major ethical concerns. Comparative studies comprehensively characterizing the MSC phenotype across several tissue sources are still lacking...

Patients with peripheral artery disease (PAD) and intermittent claudication (IC) have impaired functional status and quality of life. However, little is known about which factors are associated with poorer health status at the time of initial presentation for PAD specialty care. Characterization of such features might provide insight into disparities that impact health status in this population. A total of 1258 patients from the United States, the Netherlands and Australia with new or worsened IC were enrolled at their first PAD specialty care visit between June 2011 and December 2015...
