Imaging of the orbit plays an important role in the workup of orbital emergencies. Orbital imaging is particularly useful in the emergency department, where clinical history and physical examination may be limited or delayed until the exclusion or treatment of more life-threatening conditions. Cross-sectional orbital imaging with multidetector computed tomography (CT) and magnetic resonance (MR) imaging is commonly performed in addition to ultrasonography. In an emergent setting, CT is the preferred modality when evaluating for intraorbital foreign bodies, fractures, or calcifications within a mass lesion...

The long-term chemical instability and the presence of toxic Pb in otherwise stellar solar absorber APbX3 made of organic molecules on the A site and halogens for X have hindered their large-scale commercialization. Previously explored ways to achieve Pb-free halide perovskites involved replacing Pb(2+) with other similar M(2+) cations in ns(2) electron configuration, e.g., Sn(2+) or by Bi(3+) (plus Ag(+)), but unfortunately this showed either poor stability (M = Sn) or weakly absorbing oversized indirect gaps (M = Bi), prompting concerns that perhaps stability and good optoelectronic properties might be contraindicated...

Sports-related injuries are a frequent cause of visits to the emergency department (ED) across the United States. A majority of these injuries affect the lower extremities with the ankle as the most frequently reported site. Most sports-related injuries are not severe enough to require inpatient hospitalization; however, they often lead to acute distress and pain which require prompt treatment with analgesics. Approximately 22% of patients who presented to the ED required pharmacotherapy for acute pain management...

SUMO post-translational modification of proteins or SUMOylation ensures normal cell function. Disruption of SUMO dynamics prompts various pathophysiological conditions, including cancer. The burden of deSUMOylating the large SUMO-proteome rests on 6 full-length mammalian SUMO-proteases or SENP. While multiple SENP isoforms exist, the function of these isoforms remains undefined. We now delineate the biological role of a novel SENP7 isoform SENP7S in mammary epithelial cells. SENP7S is the predominant SENP transcript in human mammary epithelia but is significantly reduced in precancerous ductal carcinoma in situ and all breast cancer subtypes...

This study examined the uncertain responses of 56 alleged sexual abuse victims, aged 5-17 years, testifying in Scottish criminal court trials. Don't know/remember ground rules were explained to 38% of the children and each child reported uncertainty in response to 15% of the questions on average. Uncertain responding was associated with expressions of resistance and confusion, questioning context (proportionally more regarding substantive than non-substantive issues), question content (least to disclosure-focused questions), utterance type (more to directives, particularly those posed by defense lawyers; more to recall-based than recognition prompts), and age (children in mid-adolescence were less likely to respond uncertainly than those who were either older or younger)...

In Euglena cells under anaerobic conditions, paramylon, the storage polysaccharide, is promptly degraded and converted to wax esters. The wax esters synthesized are composed of saturated fatty acids and alcohols with chain lengths of 10-18, and the major constituents are myristic acid and myristyl alcohol. Since the anaerobic cells gain ATP through the conversion of paramylon to wax esters, the phenomenon is named "wax ester fermentation". The wax ester fermentation is quite unique in that the end products, i...

BACKGROUND: The discovery that 5-methylcytosine (5mC) can be oxidized to 5-hydroxymethylcytosine (5hmC) by the ten-eleven translocation (TET) proteins has prompted wide interest in the potential role of 5hmC in reshaping the mammalian DNA methylation landscape. The gold-standard bisulphite conversion technologies to study DNA methylation do not distinguish between 5mC and 5hmC. However, new approaches to mapping 5hmC genome-wide have advanced rapidly, although it is unclear how the different methods compare in accurately calling 5hmC...

BACKGROUND: Dural arteriovenous fistula (DAVF) with cortical venous drainage (CVD) are known to be aggressive in clinical course and are usually managed promptly. Spontaneous resolution of DAVF is a rare phenomenon and usually occurs in benign type of fistulas. Spontaneous thrombosis of aggressive DAVF is an extremely rare occurrence. The present study aims to identify the incidence and factors determining spontaneous resolution of aggressive DAVF. METHODS: All the patients presenting to our institution with suspected DAVF during the study period (July 2013 - December 2015) were prospectively enrolled into a database...

REVIEW
John C Clamp, Denis H Lynn
Biology is now turning toward a more integrative approach to research, distinguished by projects that depend on collaboration across hierarchical levels of organization or across disciplines. This trend is prompted by the need to solve complex, large-scale problems and includes disciplines that could be defined as integrative biodiversity. Integrative biodiversity of protists, including that of ciliates, is still partially in its infancy. This is the result of a shortage of historical data resources such as curated museum collections...

BACKGROUND: Use of antigen-detecting malaria rapid diagnostic tests (RDTs) has increased exponentially over the last decade. WHO's Global Malaria Programme, FIND, and other collaborators have established a quality assurance scheme to guide product selection, lot verification, transport, storage, and training procedures. Recent concerns over the quality of buffer packaging and test accessories suggest a need to include these items in product assessments. This paper describes quality problems with buffer and accessories encountered in a project promoting private sector RDT use in five African countries and suggests steps to avoid or more rapidly identify and resolve such problems...

The aim of this study is to compare between proton boron fusion therapy (PBFT) and boron neutron capture therapy (BNCT) and to analyze dose escalation using a Monte Carlo simulation. We simulated a proton beam passing through the water with a boron uptake region (BUR) in MCNPX. To estimate the interaction between neutrons/protons and borons by the alpha particle, the simulation yielded with a variation of the center of the BUR location and proton energies. The variation and influence about the alpha particle were observed from the percent depth dose (PDD) and cross-plane dose profile of both the neutron and proton beams...

Intravitreal ranibizumab (RBZ) has been shown in multiple randomized clinical trials to be a valuable treatment for diabetic macular edema (DME), promoting a significant improvement in best-corrected visual acuity (BCVA) and in anatomic outcomes. Compared to sham (RISE and RIDE studies), RBZ rapidly and sustainably improved BCVA and decreased macular edema at 2 years, reducing the risk of further vision loss, with low rates of local or systemic side effects. Compared to macular laser photocoagulation (READ-2 study), RBZ provided a greater improvement in BCVA and regression in foveal thickness, but required a higher number of injections compared to patients treated with both RBZ and laser...

Diabetic retinopathy (DR), a major microvascular complication of diabetes, has a significant impact on the world's health systems. Globally, the number of people with DR will grow from 126.6 million in 2010 to 191.0 million by 2030, and it is estimated that the number with vision-threatening diabetic retinopathy will increase from 37.3 million to 56.3 million if prompt action is not taken. Lack of early diagnosis and management is the leading cause of blindness in working-age populations The gap between demand and annual eye examinations has been a big challenge...
