#1
Robert W Corkery, Eric C Tyrode
Lycaenid butterflies from the genera Callophrys, Cyanophrys and Thecla have evolved remarkable biophotonic gyroid nanostructures within their wing scales that have only recently been replicated by nanoscale additive manufacturing. These nanostructures selectively reflect parts of the visible spectrum to give their characteristic non-iridescent, matte-green appearance, despite a distinct blue-green-yellow iridescence predicted for individual crystals from theory. It has been hypothesized that the organism must achieve its uniform appearance by growing crystals with some restrictions on the possible distribution of orientations, yet preferential orientation observed in Callophrys rubi confirms that this distribution need not be uniform...

Autism spectrum disorder (ASD), the fastest growing developmental disability in the United States, represents a group of neurodevelopmental disorders characterized by impaired social interaction and communication as well as restricted and repetitive behavior. The underlying cause of autism is unknown and therapy is currently limited to targeting behavioral abnormalities. Emerging studies suggest a link between mitochondrial dysfunction and ASD. Here, we review the evidence demonstrating this potential connection...

The oligometastatic melanoma is a peculiar stage of cancer progression which is initially restricted to the initial body area. In most instances, only a small number of metastases are simultaneously present. The oligometastatic stage is synchronous when metastases are disclosed at the time of initial diagnosis of the primary cancer. Metastases are metachronous when they are detected after the initial treatment of the primary neoplasm. A variant of the disease is called the smouldering disease when cutaneous metastases grow or regress in unison...

The Bartonella gene transfer agent (BaGTA) is an archetypical example for domestication of a phage-derived element to permit high-frequency genetic exchange in bacterial populations. Here we used multiplexed transposon sequencing (TnSeq) and single-cell reporters to globally define the core components and transfer dynamics of BaGTA. Our systems-level analysis has identified inner- and outer-circle components of the BaGTA system, including 55 regulatory components, as well as an additional 74 and 107 components mediating donor transfer and recipient uptake functions...

The war on drugs is usually associated with criminal policies aimed at stemming consumption of drugs such as heroin, cocaine, and cannabis, less so with enhancement drugs like those used in sport. As drug use in sport, or doping, has become more visibly widespread, policies aimed at combating the issue have become more restrictive, intrusive, and harsh. In this article we draw new comparisons between the wider war on drugs and recent developments in sports anti-doping. We identify a growing trend towards criminalisation of traffickers and users, and associate that with another growing trend: the testing of amateur athletes...

The limited efficacy of conventional therapies for pancreatic ductal adenocarcinoma has led to the growing interest for identifying potential antigenic targets for immunotherapy. Placenta-specific 1 (PLAC1) is a new member of cancer-testis antigens with restricted expression in normal tissues. Ectopic activation of PLAC1 has been found in different types of cancers, but its role in pancreatic ductal adenocarcinoma remains unknown. This study evaluated the protein expression of PLAC1 and its clinical significance in pancreatic ductal adenocarcinoma...

Urinary tract infections (UTIs) caused by uropathogenic Escherichia coli (UPEC) affect 150 million people annually. Despite effective antibiotic therapy, 30-50% of patients experience recurrent UTIs. In addition, the growing prevalence of UPEC that are resistant to last-line antibiotic treatments, and more recently to carbapenems and colistin, make UTI a prime example of the antibiotic-resistance crisis and emphasize the need for new approaches to treat and prevent bacterial infections. UPEC strains establish reservoirs in the gut from which they are shed in the faeces, and can colonize the periurethral area or vagina and subsequently ascend through the urethra to the urinary tract, where they cause UTIs...

Isolates of the Fusarium graminearum species complex (FGSC, n = 446) were collected from wheat spikes from northern and western regions of Iran with a history of Fusarium head blight (FHB) occurrences. The trichothecene mycotoxin genotypes/chemotypes, the associated phylogenetic species, and geographical distribution of these isolates were analyzed. Two phylogenetic species, Fusarium asiaticum and F. graminearum, were identified and were found to belong to sequence characterized amplified region (SCAR) groups V and I...

The role of auxin in ripening strawberry (Fragaria ×ananassa) fruits has been restricted to the early stages of development where the growth of the receptacle is dependent on the delivery of auxin from the achenes. At later stages, during enlargement of the receptacle, other hormones have been demonstrated to participate to different degrees, from the general involvement of gibberellins and abscisic acid to the more specific of ethylene. Here we report the involvement of auxin at the late stages of receptacle ripening...

REVIEW
Michael Luciano, Christian Brückner
The increasing popularity of porphyrins and hydroporphyrins for use in a variety of biomedical (photodynamic therapy, fluorescence tagging and imaging, photoacoustic imaging) and technical (chemosensing, catalysis, light harvesting) applications is also associated with the growing number of methodologies that enable their solubilization in aqueous media. Natively, the vast majority of synthetic porphyrinic compounds are not water-soluble. Moreover, any water-solubility imposes several restrictions on the synthetic chemist on when to install solubilizing groups in the synthetic sequence, and how to isolate and purify these compounds...

Obesity is a growing pandemic across the world. Dietary restrictions and behavior modifications alone have a limited benefit. Bariatric surgery, despite being the current gold standard, has limited acceptance by patients due to cost and associated morbidity. In our review, we have discussed nine original studies describing endoscopic sleeve gastroplasty (ESG). A total of 172 subjects successfully underwent ESG. Of 65 subjects with follow up data, 95.4% (62/65) had intact gastric sleeve confirmed via esophagogastroduodenoscopy or oral contrast study at the end of study specific follow up interval (the longest being 6 months)...

Non-adherence to the therapeutic regimen is an increasingly growing problem especially among patients undergoing hemodialysis. The aim of this study was to modify the Greek version of Simplified Medication Adherence Questionnaire (GR-SMAQ) for patients undergoing hemodialysis (GR-SMAQ-HD) and explore its validity and reliability. Between June 2016 and November 2016 a group of patients undergoing hemodialysis (N=107) completed the Greek version of SMAQ. The study was carried out in three Dialysis Units of Hospitals of Athens and Peloponnese region, Greece...

The nutritional environments that organisms experience are inherently variable, requiring tight coordination of how resources are allocated to different functions relative to the total amount of resources available. A growing body of evidence supports the hypothesis that key endocrine pathways play a fundamental role in this coordination. In particular, the insulin/insulin-like growth factor signaling (IIS) and target of rapamycin (TOR) pathways have been implicated in nutrition-dependent changes in metabolism and nutrient allocation...

BACKGROUND: Novice drivers are at relatively high risk of road traffic injury. There is good evidence that Graduated Driving Licensing (GDL) schemes reduce collisions rates, by reducing exposure to risk and by extending learning periods. Legislation for a proposed scheme in Northern Ireland was passed in 2016, providing an opportunity for future evaluation of the full public health impacts of a scheme in a European context within a natural experiment. This qualitative study was designed to inform the logic model for such an evaluation, and provide baseline qualitative data on the role of private cars in health and wellbeing...

OBJECTIVE: Uncomplicated urinary tract infections (UTIs) are the most common bacterial infections among women presenting to primary care causing rapidly increasing strains of resistant bacteria to the growing antibiotic industry. Restricting antibiotics to necessary indications is the only solution. The objectives of the study were to compare the efficacy of symptomatic treatment vs antibiotic in patients with uncomplicated UTI, in terms of individual symptom score, i.e., frequency, urgency, dysuria, supra pubic pain scores and total symptoms scores...

While there is growing interest in the potential for intranasal oxytocin (IN-OT) to improve social cognition and neurocognition (ie, nonsocial cognition) in schizophrenia, the extant literature has been mixed. Here, we perform a Bayesian meta-analysis of the efficacy of IN-OT to improve areas of social and neurocognition in schizophrenia. A systematic search of original research publications identified randomized controlled trials (RCTs) of IN-OT as a treatment for social and neurocognitive deficits in schizophrenia for inclusion...

OBJECTIVE: In recent years, there has been a blossoming of studies examining cerebrospinal fluid (CSF) as a method of studying the pathophysiology of delirium. We systematically reviewed the literature for CSF studies in delirium and provide here a summary of the implications for our understanding of delirium pathophysiology. We also summarise the methods used for CSF analysis and discuss challenges and implications for future studies. METHODS: In this systematic review, we screened MEDLINE, EMBASE, PsycINFO, Web of Science, PubMed and the Cochrane Library for articles on CSF biomarkers in delirium, published on 3 September 2016...

The dioxonapthoimidazolium YM155 is a survivin suppressant which has been investigated as an anticancer agent in clinical trials. Here, we investigated its growth inhibitory properties on a panel of immortalized and patient derived renal cell carcinoma (RCC) cell lines which were either deficient in the tumour suppressor von Hippel-Lindau (VHL) protein or possessed a functional copy. Neither the VHL status nor the survivin expression levels of these cell lines influenced their susceptibility to growth inhibition by YM155...
