Lighting a Path for Autonomous Vehicle Communication: The Effect of Light Projection on the Detection of Reversing Vehicles by Older Adult Pedestrians.

Pedestrian understanding of driver intent is key to pedestrian safety on the road and in parking lots. With the development of autonomous vehicles (AVs), the human driver will be removed, and with it, the exchange that occurs between drivers and pedestrians (e.g.

More than an Incidentaloma: The Nonreportable NIPT.

Noninvasive prenatal testing (NIPT), which utilizes a maternal blood sample to detect fetal gender and screen for fetal aneuploidy (abnormal chromosomes), is widely used in obstetrics to screen for Trisomies 21, 18, and 13. Per the literature, approximately 0.3% of pregnant woman's results are nonreportable.

Safety and Efficacy of a 3-Dimensional Stent Retriever With Aspiration-Based Thrombectomy vs Aspiration-Based Thrombectomy Alone in Acute Ischemic Stroke Intervention: A Randomized Clinical Trial.

Importance: The treatment effects of individual mechanical thrombectomy devices in large-vessel acute ischemic stroke (AIS) remain unclear.

Objective: To determine whether the novel 3-dimensional (3-D) stent retriever used in conjunction with an aspiration-based mechanical thrombectomy device (Penumbra System; Penumbra) is noninferior to aspiration-based thrombectomy alone in AIS.

Design, Setting, And Participants: This randomized, noninferiority clinical trial enrolled patients at 25 North American centers from May 19, 2012, through November 19, 2015, with follow-up for 90 days.

Visual recovery and OCT evolution following central retinal artery occlusion treated with intra-arterial verapamil and alteplase infusion.

A 69-year-old woman presented with a "veil" over the left eye. Clinical examination demonstrated signs of central retinal artery occlusion. Visual acuity was compromised to 1/200 E in the left eye.

Factors affecting umbilical cord blood stem cell suitability for transplantation in an in utero collection program.

Background: The greatest limiting factor in the use of umbilical cord blood (UCB) for transplantations is the number of stem cells available in any given collected unit. This study examines maternal, neonatal, and obstetric factors that influence the suitability for banking and transplantation of UCB units collected in utero.

Study Design And Methods: This study examined 7839 UCB units collected in utero at two hospitals from August 1, 2008, to August 31, 2011.

Developing a wellness program for people with multiple sclerosis: description and initial results.

Because multiple sclerosis (MS) is a multidimensional chronic disease, effective management of the illness requires a multidimensional approach. We describe a wellness program that was designed to facilitate positive health choices throughout the course of MS and present initial data analyses. We hypothesized that over the course of the program, participants would demonstrate improvement in the domains assessed.

Microcapsules with three orthogonal reactive sites.

Polymeric microcapsules containing reactive sites on the shell surface and two orthogonally reactive polymers encapsulated within the interior are selectively labeled. The capsules provide three spatially separate and differentially reactive sites. Confocal fluorescence microscopy is used to characterize the distribution of labels.

Use of bifunctional ureas to increase the rate of proline-catalyzed alpha-aminoxylations.

The rate of the proline-catalyzed alpha-aminoxylation of aldehydes is significantly increased in the presence of a bifunctional urea. Structure-activity relationship data indicate that both an amine and a urea are crucial for rate enhancement. The evidence presented herein suggests that this rate enhancement originates from the hydrogen bonding interaction between the bifunctional urea and an oxazolidinone intermediate to increase the rate of enamine formation.

A general approach to creating soluble catalytic polymers heterogenized in microcapsules.

A general method for preparing site-isolated polymeric catalysts is presented. Linear chloromethyl and azide polymers have been sequestered within polyurea microcapsules and small molecule catalysts soaked through the shell walls to functionalize the soluble polymers. Reaction onto each type of support is quantitative and MacMillan, DMAP, and TEMPO test catalysts are shown to have faster reaction rates than the analogous resin-supported catalysts.

Disease-control rates following intensity-modulated radiation therapy for small primary oropharyngeal carcinoma.

Background: The purpose of this study was to assess the ability of intensity-modulated radiation therapy (IMRT) to achieve favorable disease-control rates while minimizing parotid gland doses in patients treated for small primary tumors of the oropharynx.

Methods And Materials: We retrospectively identified all patients who received IMRT as treatment for a small (<4 cm) primary tumor of the oropharynx between October 2000 and June 2002. Tumor characteristics, IMRT parameters, and patient outcomes were assessed.

Microencapsulated linear polymers: "soluble" heterogeneous catalysts.

A new strategy for supporting catalysts based on the microencapsulation of linear polymers is presented. In this paper, we present a DMAP capsule that is capable of catalyzing acylation reactions. The catalyst is compared to DMAP on cross-linked and linear polystyrene, as well as small molecule DMAP.

The effects of maxillary protraction therapy with or without rapid palatal expansion: a prospective, randomized clinical trial.

Introduction: The purpose of this controlled randomized clinical trial was to quantify the effects of maxillary protraction with or without palatal expansion.

Methods: Forty-six children aged 5 to 10 years were randomly assigned to 1 of 3 groups: (1) facemask with palatal expansion, (2) facemask without palatal expansion, and (3) observation for 12 months. Cephalometric analysis with traditional cephalometric measurements, an x-y coordinate system, and an occlusal-plane analysis were used.

Cellular-free magnesium depletion in brain and muscle of normal and preeclamptic pregnancy: a nuclear magnetic resonance spectroscopic study.

Preeclampsia is a pregnancy disorder of unknown origin, characterized by vasospasm, elevated blood pressure, and increased neuromuscular irritability, features common to syndromes of magnesium deficiency. Evidence of serum and ionized magnesium metabolism disturbances have been observed in women with preeclampsia. This and the therapeutic utility of magnesium in preeclampsia led us to investigate the extent to which an endogenous tissue magnesium deficiency might be present in and contribute to its pathophysiology.

Calcium channel blocker, nimodipine, for the treatment of bipolar disorder during pregnancy.

Bipolar disorder in pregnancy was treated with nimodipine, because of lithium-induced nephrogenic diabetes insipidus. A 33-year-old primigravida woman at approximately 22 weeks 6 days of gestation had increasing blood pressure since 16 weeks of gestation, despite methyldopa 500 mg twice daily. She also had hypothyroidism and bipolar disorder, which were treated with levothyroxine and lithium carbonate, respectively.
