A 28-year-old lady with a refractive error of -11.0 D sphere/-1.50 D cylinder at 160 degrees in the right eye underwent an uneventful Implantable Collamer Lens surgery (ICL) with a V4c model, which uses a central Aquaport. This ICL does not require preoperative laser iridotomy or surgical iridectomy, as the centraflow opening is designed to prevent pupillary block. At postoperative day 1, her visual acuity in the right eye was 20/400, with diffuse microcystic corneal edema with fixed, dilated pupil and high intraocular pressure...

Coumadin (rac-warfarin) is the most commonly used anticoagulant in the world, yet its clinical use is often challenging due to a narrow therapeutic range and inter-individual variations in response. A critical contributor to the uncertainty is variability in warfarin metabolism, which includes mostly oxidative but also reductive pathways. Reduction of each warfarin enantiomer yields two warfarin alcohol isomers, and the corresponding four alcohols retain varying levels of anticoagulant activity. Studies on the kinetics of warfarin reduction have often lacked resolution of parent drug enantiomers and suffered from co-elution of pairs of alcohol metabolites; thus, those studies fail to establish the importance of individual, stereospecific reductive pathways...

Results are reported from an improved measurement of ν_{μ}→ν_{e} transitions by the NOvA experiment. Using an exposure equivalent to 6.05×10^{20} protons on target, 33 ν_{e} candidates are observed with a background of 8.2±0.8 (syst.). Combined with the latest NOvA ν_{μ} disappearance data and external constraints from reactor experiments on sin^{2}2θ_{13}, the hypothesis of inverted mass hierarchy with θ_{23} in the lower octant is disfavored at greater than 93% C.L. for all values of δ_{CP}.

Traditional methods for deriving computationally-generated collision cross sections for comparisons with ion mobility-mass spectrometry data require 3-dimensional energy-minimized structures and are often time consuming, preventing high throughput implementation. Here, we introduce a method to predict ion mobility collision cross sections of lipids and peptide analogs important in prebiotic chemistry and other fields. Using less than 100 2-D molecular descriptors this approach resulted in prediction errors of less than 2%...

Techniques to assess violence risk are increasingly common, but no systematic approach exists to help clinicians decide which psychiatric patients are most in need of a violence risk assessment. The Fordham Risk Screening Tool (FRST) was designed to fill this void, providing a structured, systematic approach to screening psychiatric patients and determining the need for further, more thorough violence risk assessment. The FRST was administered to a sample of 210 consecutive admissions to the civil psychiatric units of an urban medical center, 159 of whom were subsequently evaluated using the Historical Clinical Risk Management-20, version 3, to determine violence risk...

PROBLEM: Levels of placental growth factor (PlGF) peak during third trimester of pregnancy, a time when women are at increased risk of virus-induced morbidity. We hypothesized PlGF might contribute to an exaggerated inflammatory response to Toll-like receptor (TLR) activation. METHOD OF STUDY: Primary human adult and cord blood CD14(+) cells were cultured in the presence of TLR ligands and/or PlGF. RESULTS: PlGF significantly enhanced the magnitude and duration of TNF messenger RNA and protein production by TLR-7/8-activated monocytes, and increased subsequent production of TNF-independent inflammatory cytokines...

Background -Contemporary ST-elevation myocardial infarction (STEMI) management involves primary percutaneous coronary intervention (PCI) with on-going studies focusing on infarct size reduction utilizing ancillary therapies. N-acetylcysteine (NAC) is an antioxidant with reactive oxygen species scavenging properties that also potentiates the effects of nitroglycerin (NTG) and thus represents a potentially beneficial ancillary therapy in primary PCI. The NACIAM (NACIn Acute Myocardial infarction) trial examined the effects of NAC on infarct size in STEMI patients undergoing PCI...

INTRODUCTION: The most common fractures during vaginal delivery occur in the clavicle, humerus, and femur. Cesarean section reduces the chances of a child having a birth injury. However, in some difficult extractions, long bone fractures may occur. Cesarean section further reduces the incidence of birth injuries, especially in a breech delivery. Maneuvers employed during cesarean section, energetic traction, improper uterine incisions, and contracted uterus may cause these injuries. In the medical literature, there are few articles highlighting the occurrence of long bone fractures during cesarean section...

Childhood obesity is a major public health problem. An association between obesity and dental caries, the most prevalent disease of childhood, has been identified. One explanation for the association is that consumption of sugar-sweetened beverages and frequent snacking on carbohydrate-rich foods are common risk factors for development of both obesity and caries. The Robert Wood Johnson Foundation (RWJF) has been at the forefront of national efforts to promote healthy weight in children. As part of these efforts, RWJF sponsored the Healthy Futures: Engaging the Oral Health Community in Childhood Obesity Prevention National Conference, held on November 3-4, 2016, at Georgetown University in Washington, DC...

Cell culture has become an indispensable tool to help uncover fundamental biophysical and biomolecular mechanisms by which cells assemble into tissues and organs, how these tissues function, and how that function becomes disrupted in disease. Cell culture is now widely used in biomedical research, tissue engineering, regenerative medicine, and industrial practices. Although flat, two-dimensional (2D) cell culture has predominated, recent research has shifted toward culture using three-dimensional (3D) structures, and more realistic biochemical and biomechanical microenvironments...

Spinocerebellar degeneration, termed as ataxia is a neurological disorder of central nervous system, characterized by limb in-coordination and a progressive gait. The patient also demonstrates specific symptoms of muscle weakness, slurring of speech, and decreased vibration senses. Expansion of polyglutamine trinucleotide (CAG) within ATXN2 gene with 35 or more repeats, results in spinocerebellar ataxia type-2. Protein ataxin-2 coded by ATXN2 gene has been reported to have a crucial role in translation of the genetic information through sequestering the histone acetyl transferases (HAT) resulting in a state of hypo-acetylation...

Graphene is a promising candidate for optoelectronic applications. In this report, a double gated bilayer graphene FET has been made using a combination of electrostatic and electrolytic gating in order to form an abrupt p-n junction. The presence of two Dirac peaks in the gating curve of the fabricated device confirms the formation of a p-n junction. At low temperatures, when the electrolyte is frozen intentionally, the photovoltage exhibits a six-fold pattern indicative of the hot electron induced photothermoelectric effect that has also been seen in graphene p-n junctions made using metallic gates...
