BACKGROUND: Evidence suggests that nearly half of patients with major depressive disorder (MDD) do not achieve an adequate response to antidepressant treatments (ADTs), which impacts patients' functioning, quality of life (QoL), and well-being. This patient survey aimed to better understand patient perspectives on the emotional impact of experiencing an inadequate response to ADTs. METHODS: An online survey was conducted in 6 countries with respondents diagnosed with MDD and experiencing an inadequate response to ADTs...

The advent of the endoscope has facilitated otological surgery in recent years. Advances in optical technology have led to the development of high definition visualisation, such as 4K magnification. Narrow band imaging (NBI) has been shown to improve visualisation of tissue based on varying degrees of vascularity. This is a feasibility study, the first of its kind, aiming to investigate the appearances of middle ear anatomy and pathology (tympanic membrane, tympanosclerosis, cholesteatoma, granulation, endolymphatic sac hydrops, otosclerosis) under the NBI filter, using a high definition 4K endoscope...

Psychotropics are highly effective medications that, however, have adverse drug reactions attached to them. They are indispensable for many patients. How to cope with side effects - watchful waiting, dose reduction, change of medication, addition of an "antidote" and behavioural modifications - depends on their nature, severity and finally the patients wish. This review is meant to aid clinician's and patient's decisions in case of the occurrence of compromising, frequent adverse drug reactions.

Medicaid and uninsured patients are disadvantaged in access to care and are disproportionately Black and Hispanic. Using a national audit of primary care physicians, we examine the relationship between state Medicaid fees for primary care services and access for Medicaid, Medicare, uninsured, and privately insured patients who differ by race/ethnicity and sex. We found that states with higher Medicaid fees had higher probabilities of appointment offers and shorter wait times for Medicaid patients, and lower probabilities of appointment offers and longer wait times for uninsured patients...

One of the most important tools to identify and validate rust resistance gene function is by producing loss-of-function mutants. Mutants can be produced using irradiation, chemicals, and insertions. Among all the mutagens, ethyl methanesulfonate (EMS) and sodium azide are most favored because of the ease of use and generation of random point mutations in the genome. The mutants so produced facilitate the isolation, identification and cloning of rust resistance genes. In this chapter we describe a protocol for seed mutagenesis of wheat with EMS and sodium azide...

INTRODUCTION: The NR4A2 transcription factor is important in the development, survival and phenotype of dopaminergic neurons and it is postulated as a possible biomarker for Parkinson's disease (PD). Therefore, our aim was to analyze in a sample of a Mexican population with idiopathic PD, mutations (in two hotspot mutation regions) and two polymorphisms (rs34884856 in promotor and rs35479735 intronic regions) of the NR4A2 gene. We also evaluate the levels of NR4A2 gene expression in peripheral blood for a Mexican population, and identify whether they are associated with NR4A2 gene polymorphisms...

We demonstrate an innovative technique based on the Pancharatnam-Berry phase that can be used to determine whether an optical system characterized by a Jones matrix is homogeneous or inhomogeneous, containing orthogonal or nonorthogonal eigenpolarizations, respectively. Homogeneous systems have a symmetric geometric phase morphology showing line dislocations and sets of polarization states with an equal geometric phase. In contrast, the morphology of inhomogeneous systems exhibits phase singularities, where the Pancharatnam-Berry phase is undetermined...

Hedgehog (Hh) regulates the Cubitus interruptus (Ci) transcription factor in Drosophila melanogaster by activating full-length Ci-155 and blocking processing to the Ci-75 repressor. However, the interplay between the regulation of Ci-155 levels and activity, as well as processing-independent mechanisms that affect Ci-155 levels, have not been explored extensively. Here, we identified Mago Nashi (Mago) and Y14 core Exon Junction Complex (EJC) proteins, as well as the Srp54 splicing factor, as modifiers of Hh pathway activity under sensitized conditions...

The Exon Junction Complex (EJC) is the main mechanism by which cells select specific mRNAs for translation into protein. We hypothesised that the EJC is involved in the regulation of gene expression during the stress response in cardiac myocytes, with implications for the failing heart. In cultured rat neonatal myocytes, we examined the cellular distribution of two EJC components eIF4A3 and mago nashi homologue (Mago) in response to metabolic stress. There was significant relocalisation of eIF4A3 and Mago from the nucleus to cytoplasm following 18 hours of hypoxia...

Nonsense-mediated mRNA decay (NMD) is essential for removing premature termination codon-containing transcripts from cells. Studying the NMD pathway in model organisms can help to elucidate the NMD mechanism in humans and improve our understanding of how this biologically important process has evolved. Ciliates are among the earliest branching eukaryotes; their NMD mechanism is poorly understood and may be primordial. We demonstrate that highly conserved Upf proteins (Upf1a, Upf2 and Upf3) are involved in the NMD pathway of the ciliate, Tetrahymena thermophila...

Maize (Zea mays L.) is one of the major staple food crops of the world. However, high photoperiod sensitivity, especially for tropical germplasms, impedes attempts to improve maize agronomical traits by integration of tropical and temperate maize germplasms. Physiological and phenotypic responses of maize to photoperiod have widely been investigated based on multi-site field observations; however, proteome-based responsive mechanisms under controlled photoperiod regimes, nutrient and moisture soils are not yet well understood...

Climate change is likely to be one of the most important factors affecting our future food security. To mitigate negative impacts, we will require our crops to be more genetically diverse. Such diversity is available in crop wild relatives (CWRs), the wild taxa relatively closely related to crops and from which diverse traits can be transferred to the crop. Conservation of such genetic resources resides within the nation where they are found; therefore, national-level conservation recommendations are fundamental to global food security...

We review clinical trials of squamous cell carcinoma of the head and neck (SCCHN) to address the current and potential uses of cetuximab (CTX). PubMed was reviewed to identify papers published between 2010 and 2016. The search terms used were "cetuximab" and "head and neck cancer." A total of 634 articles were identified. Phase II or III studies with CTX in patients with advanced SCCHN without treatment or with recurrent/metastatic tumors were selected. Forty-six registries were obtained. Information was critically reviewed and relevant information presented...

Although it is currently understood that the exon junction complex (EJC) is recruited on spliced mRNA by a specific interaction between its central protein, eIF4AIII, and splicing factor CWC22, we found that eIF4AIII and the other EJC core proteins Y14 and MAGO bind the nascent transcripts of not only intron-containing but also intronless genes on Drosophila polytene chromosomes. Additionally, Y14 ChIP-seq demonstrates that association with transcribed genes is also splicing-independent in Drosophila S2 cells...

BACKGROUND AND PURPOSE: Access to primary care remains a problem for a substantial portion of the U.S. population, and is predicted to worsen due to an aging population and the increasing burden of chronic diseases. Better integration of nurse practitioners (NPs) into the primary care workforce is a possible solution. We examine offers of appointments with NPs if a requested primary care physician is unavailable. METHODS: Data are from a 2013 audit (simulated patient) study requesting appointment information from a national random sample of primary care physicians...
