Toward Eclipse Mapping of Hot Jupiters

Recent Spitzer infrared measurements of hot Jupiter eclipses suggest that eclipse mapping techniques could be used to spatially resolve the day-side photospheric emission of these planets using partial occultations. As a first step in this direction, we simulate ingress/egress lightcurves for the three brightest known eclipsing hot Jupiters and evaluate the degree to which parameterized photospheric emission models can be distinguished from each other with repeated, noisy eclipse measurements. We find that the photometric accuracy of Spitzer is insufficient to use this tool effectively. On the other hand, the level of photospheric details that could be probed with a few JWST eclipse measurements could greatly inform hot Jupiter atmospheric modeling efforts. A JWST program focused on non-parametric eclipse map inversions for hot Jupiters should be actively considered.Comment: 32 pages, 6 figures, 3 tables, accepted for publication in Ap

The dick pic : harassment, curation, and desire

The combined rise of digital photography and social media has expanded what might be considered photo worthy. Among the pouting selfies and food stuffs of the day exists the ubiquitous dick pic. The mainstream media generally focuses on dick pics of the unsolicited kind, which, negatively positioned, are commonly associated with heterosexual harassment. Considering the ubiquity of dick pics across apps and platforms, research on the topic nevertheless remains scarce. In this article, we examine the dick pic as an online communicative form, first considering how it manifests the ability to harass and then moving beyond this dominant framing to analysis of contexts where such images are collated, expected, and sought after. Through this analysis of dick pics as figures and actors of harassment, curation, and desire, we demonstrate the simultaneous tenacity and flexibility of their meanings in connection with the dynamics of consent and non-consent, intimacy and distance, and complex circuits of desire. We further address the role of platforms, apps, and app stores, via their community standards and terms of use, in shaping the nature, and presence, of dick pics, and discuss the affective and communicative functions that these affordances serve (or fail to serve). Our analysis of three key modes of engagement with dick pics demonstrates the ambiguity and multiple valences of the phenomenon addressed

Dietary modification for women after breast cancer treatment: a narrative review

Diet is thought to account for about 25% of cancers in developed countries. It is well documented that the risks associated with both the breast cancer itself and its treatments are important for women previously treated for breast cancer. Women are at risk of recurrence of the primary disease and prone to develop treatment-induced co-morbidities, some of which are thought to be modified by diet. With a view to making dietary recommendations for the breast cancer patients we encounter in our clinical nursing research, we mined the literature to scope the most current robust evidence concerning the role of the diet in protecting women against the recurrence of breast cancer and its potential to ameliorate some of the longer-term morbidities associated with the disease. We found that the evidence about the role of the diet in breast cancer recurrence is largely inconclusive. However, drawing on international guidelines enabled us to make three definitive recommendations. Women at risk of breast cancer recurrence, or who experience co-morbidities as a result of treatment, should limit their exposure to alcohol, moderate their nutritional intake so it does not contribute to postmenopausal weight gain, and should adhere to a balanced diet. Nursing education planned for breast cancer patients about dietary issues should ideally be individually tailored, based on a good understanding of the international recommendations and the evidence underpinning the

A Flagellar A-Kinase Anchoring Protein with Two Amphipathic Helices Forms a Structural Scaffold in the Radial Spoke Complex

A-kinase anchoring proteins (AKAPs) contain an amphipathic helix (AH) that binds the dimerization and docking (D/D) domain, RIIa, in cAMP-dependent protein kinase A (PKA). Many AKAPs were discovered solely based on the AH–RIIa interaction in vitro. An RIIa or a similar Dpy-30 domain is also present in numerous diverged molecules that are implicated in critical processes as diverse as flagellar beating, membrane trafficking, histone methylation, and stem cell differentiation, yet these molecules remain poorly characterized. Here we demonstrate that an AKAP, RSP3, forms a dimeric structural scaffold in the flagellar radial spoke complex, anchoring through two distinct AHs, the RIIa and Dpy-30 domains, in four non-PKA spoke proteins involved in the assembly and modulation of the complex. Interestingly, one AH can bind both RIIa and Dpy-30 domains in vitro. Thus, AHs and D/D domains constitute a versatile yet potentially promiscuous system for localizing various effector mechanisms. These results greatly expand the current concept about anchoring mechanisms and AKAPs

Comparison of outcomes following arthroscopic capsular release for idiopathic, diabetic and secondary adhesive capsulitis of the shoulder: a systematic review

Introduction: Arthroscopic capsular release for adhesive capsulitis of the shoulder is a treatment option. The present study aimed to investigate the clinical outcomes following arthroscopic capsular release among idiopathic, diabetic and secondary adhesive capsulitis. Hypothesis: Different aetiological groups yield variable outcomes following arthroscopic capsular release. Materials and Methods: A literature search was performed using MEDLINE, EMBASE, CINAHL and the Cochrane Database in April 2017. Comparative studies that reported range of motion or functional outcomes following arthroscopic capsular release in patients with adhesive capsulitis were included. A systematic review of the studies was conducted following the PRISMA guidelines. Results: Six studies met the eligibility criteria. The overall population included 463 patients; 203 idiopathic, 61 diabetic and 199 secondary cases. Of four studies comparing idiopathic and diabetic patients, three reported significantly worse range of movement and function in the diabetic group at various follow up points. No significant difference in function and motion was reported between the idiopathic and secondary groups. Recurrent pain was highest in diabetic patients (26%) compared to idiopathic groups (0%) and the secondary group had a higher rate of revision surgery when compared to the idiopathic group (8.1% vs. 2.4%) Discussion: Arthroscopic capsular release has a high success rate regardless of the underlying aetiology. However, diabetic patients are reported to have more residual pain, reduced motion and inferior function compared to idiopathic cases. The rate of revision capsular release is higher among patients with post-surgical adhesive capsulitis when compared to idiopathic cases. Level of evidence: Level IV, systematic review

The Neuroprotective Potential of Cyanidin-3-glucoside Fraction Extracted from Mulberry Following Oxygen-glucose Deprivation

In this study, cyanidin-3-glucoside (C3G) fraction extracted from the mulberry fruit (Morus alba L.) was investigated for its neuroprotective effects against oxygen-glucose deprivation (OGD) and glutamate-induced cell death in rat primary cortical neurons. Cell membrane damage and mitochondrial function were assessed by LDH release and MTT reduction assays, respectively. A time-course study of OGD-induced cell death of primary cortical neurons at 7 days in vitro (DIV) indicated that neuronal death was OGD duration-dependent. It was also demonstrated that OGD for 3.5 h resulted in approximately 50% cell death, as determined by the LDH release assay. Treatments with mulberry C3G fraction prevented membrane damage and preserved the mitochondrial function of the primary cortical neurons exposed to OGD for 3.5 h in a concentration-dependent manner. Glutamate-induced cell death was more pronounced in DIV-9 and DIV-11 cells than that in DIV-7 neurons, and an application of 50µM glutamate was shown to induce approximately 40% cell death in DIV-9 neurons. Interestingly, treatment with mulberry C3G fraction did not provide a protective effect against glutamate-induced cell death in primary cortical neurons. On the other hand, treatment with mulberry C3G fraction maintained the mitochondrial membrane potential (MMP) in primary cortical neurons exposed to OGD as assessed by the intensity of rhodamine-123 fluorescence. These results therefore suggest that the neuroprotective effects of mulberry C3G fraction are mediated by the maintenance of the MMP and mitochondrial function but not by attenuating glutamate-induced excitotoxicity in rat primary cortical neurons
