PURPOSE: Sight-threatening injuries associated with orbital fractures are of major concern to maxillofacial surgeons whom are often the first asked to assess these patients. Eliciting signs and symptoms that are predictive of these injuries would allow expedited ophthalmic consultation and appropriate management. We hypothesized that abnormal pupillary response is predictive of major ocular injuries. PATIENTS AND METHODS: A retrospective cohort study of patients with facial fractures was instituted with review of all associated ophthalmic injuries...

Despite threats of species extinctions, taxonomic crises, and technological advances in genomics and natural history database informatics, we are still distant from cataloguing all of the species of life on earth. Amphibians and reptiles are no exceptions; in fact new species are described nearly every day and many species face possible extinction. The number of described species continues to climb as new areas of the world are explored and as species complexes are examined more thoroughly. The use of DNA barcoding provides a mechanism for rapidly estimating the number of species at a given site and has the potential to record all of the species of life on Earth...

Improvements in feed efficiency of beef cattle have the potential to increase producer profitability and simultaneously lower the environmental footprint of beef production. Although there are many different approaches to measuring feed efficiency, residual feed intake (RFI) has increasingly become the measure of choice. Defined as the difference between an animal's actual and predicted feed intake (based on weight and growth), RFI is conceptually independent of growth and body size. In addition, other measurable traits related to energy expenditure such as estimates of body composition can be included in the calculation of RFI to also force independence from these traits...

To improve the ocular bioavailability of the strongly hydrophilic moxifloxacin hydrochloride, hyaluronic-acid-modified lipid-polymer hybrid nanoparticles (HA-LCS-NPs) were designed and characterized. An in vivo precorneal retention study in rabbits showed that the mean residence time (MRT) and area under the curve (AUC0-6h ) of HA-LCS-NPs were up to 6.74-fold and 4.29-fold higher than those of the commercial product. An in vitro corneal penetration study in rabbits demonstrated that the apparent permeability coefficient (Papp) of HA-LCS-NPs was increased by 3...

Fundamental understanding of how the hydrophobicity impacts cellular interactions of engineered nanoparticles is critical to their future success in healthcare. Herein, we report that inserting hydrophobic octanethiol onto the surface of zwitterionic luminescent glutathione coated gold nanoparticles (GS-AuNPs) of 2 nm enhanced their affinity to the cellular membrane and increased cellular uptake kinetics by more than one order of magnitude, rather than inducing the accumulation of the AuNPs in the bilayer core or enhancing their passive diffusion...

REVIEW
Mayur S Narkhede, Bruce D Cheson
Follicular lymphoma is the second most common subtype of non-Hodgkin lymphoma with an estimated 3.18 cases per 100,000 people. Despite the prolongation of survival with chemoimmunotherapy, variability in response to initial treatment and outcome still exists. Whereas prolonging overall survival is important, it is generally an unreasonable primary endpoint in the front-line setting. The long follow-up needed and the influence of subsequent therapies creates a potential bias. Thus, clinical trials require approximately 5 to 8 years from activation to completion and analysis of outcomes...

Face transplantation has evolved over the last 12 years into a safe and feasible reconstructive solution, with good aesthetic and functional outcomes for patients with severe facial defects who are not amenable to reconstruction through conventional and autologous approaches. Among patients who underwent face transplantation to date, a significant proportion did so following trauma, mostly ballistic and thermal injuries. It is therefore important for trauma surgeons who deal with these injuries regularly to be familiar with the literature on face transplantation following traumatic injuries...

Metastatic disease is the principal cause of prostate-cancer-related mortality. Our ability to accurately recapitulate the spread of prostate cancer to bone - the most common site of metastasis - is critical to the development of novel metastasis-directed therapies. Several translational models of prostate cancer bone metastasis have been developed, including animal models, cell line injection models, 3D in vitro models, bone implant models, and patient-derived xenograft models. The use of these models has led to numerous advances in elucidating the molecular mechanisms of metastasis and innovations in targeted therapy...

AIMS: Hemostasis is a limiting factor for discharge after uncomplicated transradial procedures. The potassium ferrate hemostatic patch (PFHP) may serve as an adjunct to the air-bladder TR band (TRB) and allow expedited deflation of the TRB. METHODS AND RESULTS: Prospective multicenter randomized controlled trial comparing radial hemostatic protocols. Deflation of the TRB was attempted at 40 minutes with PFHP and at 120 minutes without the PFHP. The primary outcome was time to full deflation of the TRB with hemostasis...

Homozygous mutations of human HTRA1 cause cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL). HtrA1-/- mice were examined for arterial abnormalities. Although their cerebral arteries were normal, the thoracic aorta was affected in HtrA1-/- mice. The number of vascular smooth muscle cells (VSMCs) in the aorta was increased in HtrA1-/- mice of 40 weeks or younger, but decreased thereafter. The cross-sectional area of the aorta was increased in HtrA1-/- mice of 40 weeks or older...

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a torso hemorrhage control technique. To expedite deployment, inflation is frequently performed as a blind technique with minimal imaging, which carries a theoretical risk of aortic injury. The objective of this study was to examine the relationship between balloon inflation, deformation and the risk of aortic rupture. Methods: Compliant balloon catheters were incrementally inflated in segments of cadaveric swine aorta...

A series of recent US Food and Drug Administration (FDA) approvals (such as Sarepta's Exondys 51, Merck's Keytruda, and Portola's Bevyxxa) has generated significant interest within the drug development ecosystem. Facilitated regulatory pathways aimed toward expediting medicines to patients suffering from serious and life-threatening conditions are a good thing, even if it raises curiosity and introduces some degree of uncertainty. Over the last 20 years, two key words in drug development have been speed and innovation...

The Southern Ocean is a hotspot of the climate-relevant organic sulfur compound dimethyl sulfide (DMS). Spatial and temporal variability in DMS concentration is higher than in any other oceanic region, especially in the marginal ice zone. During a one-week expedition across the continental shelf of the West Antarctic Peninsula (WAP), from the shelf break into Marguerite Bay, in January 2015, spatial heterogeneity of DMS and its precursor dimethyl sulfoniopropionate (DMSP) was studied and linked with environmental conditions, including sea-ice melt events...

Proteostasis is critical to maintain organismal viability, a process counteracted by aging-dependent protein aggregation. Chaperones of the heat shock protein (HSP) family help control proteostasis by reducing the burden of unfolded proteins. They also oversee the formation of protein aggregates. Here, we explore how AMPylation, a posttranslational protein modification that has emerged as a powerful modulator of HSP70 activity, influences the dynamics of protein aggregation. We find that adjustments of cellular AMPylation levels in Caenorhabditis elegans directly affect aggregation properties and associated toxicity of amyloid-β (Aβ), of a polyglutamine (polyQ)-extended polypeptide, and of α-synuclein (α-syn)...
