We report a case in which a radial arterial line was placed prior to induction of general anaesthesia in a 76 year old male with prostate cancer and multiple co-morbidities who presented for thoracoscopic resection of a right lower lobe carcinoid lung tumor. The patient's intra-operative course was complicated by acute blood loss requiring conversion to an open procedure. A subsequent injury to the superior vena cava resulted in the need for immediate re-exploration at the conclusion of surgery. While the arterial line was still indicated in this patient's postoperative course in the ICU, malfunction on post-operative day one resulted in removal of the catheter...

The discharge of heavy metal ions such as Cu2+ and Pb2+ poses a severe threat to public health and the environment owing to their extreme toxicity and bioaccumulation through food chains. Herein, we report a novel organic-inorganic hybrid adsorbent, Al(OH)3 -poly(acrylamide-dimethyldiallylammonium chloride)-graft-dithiocarbamate (APD), for rapid and effective removal of Cu2+ and Pb2+ . In this adsorbent, the "star-like" structure of Al(OH)3 -poly(acrylamide-dimethyldiallylammonium chloride) served as the support of dithiocarbamate (DTC) functional groups for easy access of heavy metal ions and assisted development of large and compact floccules...

316L stainless steel samples have been prepared by selective laser melting (SLM) using a pulsed laser mode and different laser powers and scanning patterns. The as-fabricated samples were found to be dominated by clusters of nano-sized γ needles or cells. TEM imaging shows that these needles contain a high population of dislocations while TEM-EDX analysis reveals high chemical homogeneity throughout the as-fabricated samples as evidenced by the fact that there is even no micro-/nano-segregation at interfaces between neighbouring γ needles...

K-ion batteries (KIBs) are now drawing increasing research interest as an inexpensive alternative to Li-ion batteries (LIBs). However, due to the large size of K+, stable electrode materials capable of sustaining the repeated K+ in-tercalation/deintercalation cycles are extremely deficient especially if a satisfactory reversible capacity is expected. Herein, we demonstrated that the structural engineering of carbon into a hollow interconnected architecture, a shape similar to the neuron-cell network, promised high conceptual and technological potential for a high-performance KIBs anode...

Improvement of statistical methods is crucial for realizing the potential of increasingly dense genetic markers. Bayesian methods treat all markers as random effects, exhibit an advantage on dense markers, and offer the flexibility of using different priors. In contrast, genomic best linear unbiased prediction (gBLUP) is superior in computing speed, but only superior in prediction accuracy for extremely complex traits. Currently, the existing variety in the BLUP method is insufficient for adapting to new sequencing technologies and traits with different genetic architectures...

BACKGROUND: Myxomatous mitral valve disease (MMVD) is one of the most prevalent valvular heart diseases, while back pain, neck pain and upper-extremity numbness are some of the most common complaints in outpatient settings. Decreased thoracic kyphosis (straight back) is a known cause of hastening back or neck problems, radiculopathy, or even myelopathy. The study aim was to examine the relationship between MMVD, straight back, and the need for cervical fusion. METHODS: In this single-center retrospective study, patients who underwent mitral valve repair or replacement due to MMVD (cases) based on age, gender and body mass index (BMI), were matched with patients who underwent coronary artery bypass grafting (CABG) surgery and had no history of mitral valve disease (controls)...

OBJECTIVES: This study sought to develop a formula from a large population-based study that best fit the QT-heart rate (HR) relationship independent of the standard mathematical relationships. BACKGROUND: Attempts to adjust or correct for the impact of HR on the QT interval (QTc) have applied various mathematical equations to electrocardiographic (ECG) data rather than allowing the data to determine the form of the relationship. METHODS: A spline correction function was developed using the ECG data from NHANES (National Health and Nutrition Examination Surveys) II and III...

We report a simple pyrene-based fluorescent probe, sodium 8-(2,4-dinitrophenoxy)pyrene-1,3,6-trisulfonate (HPTS-DNP), for the ultrasensitive and visual detection of thiophenol in 100% aqueous media. The sensing mechanism of this method is based on nucleophilic aromatic substitution on HPTS-DNP caused by thiophenol to afford a highly fluorescent product, 8-hydroxypyrene-1,3,6-trisulfonic acid trisodium salt (HPTS). The extremely low fluorescence background of HPTS-DNP and high quantum yield of HPTS ensure the superior sensing performance toward thiophenol, including rapid responses, off-on detection mode and excellent sensitivity...

Tiffany-Heather Ulep, Jeong-Yeol Yoon
Application of optically superior, tunable fluorescent nanotechnologies have long been demonstrated throughout many chemical and biological sensing applications. Combined with microfluidics technologies, i.e. on lab-on-a-chip platforms, such fluorescent nanotechnologies have often enabled extreme sensitivity, sometimes down to single molecule level. Within recent years there has been a peak interest in translating fluorescent nanotechnology onto paper-based platforms for chemical and biological sensing, as a simple, low-cost, disposable alternative to conventional silicone-based microfluidic substrates...

BACKGROUND: Anatomic reconstruction techniques are increasingly used to address cases of acromioclavicular (AC) joint chronic instability. These usually involve an additional surgical site for autograft harvesting or an allograft. PURPOSE: To describe a triple-bundle (TB) anatomic reconstruction using on-site autografts, the semiconjoint tendon (SCT) and the coracoacromial ligament (CAL), and compare its primary stability to the native AC joint ligamentous complex and to a modified Weaver-Dunn (WD) reconstruction...

Dielectric polymer nanocomposites with high dielectric constant (ε'), and low dielectric loss (tan δ) are extremely desirable in the electronics industry. Percolative polymer-graphene nanoplatelet (GnP) composites have shown great promise as dielectric materials for high-performance capacitors. Herein an industrially-viable technique for manufacturing a new class of ultralight polymer composite foams using commercial GnPs with excellent dielectric performance is presented. Using this method, the high-density polyethylene (HDPE)-GnPs composites with a microcellular structure were fabricated by melt mixing...

Many existing brain network distances are based on matrix norms. The element-wise differences may fail to capture underlying topological differences. Further, matrix norms are sensitive to outliers. A few extreme edge weights may severely affect the distance. Thus it is necessary to develop network distances that recognize topology. In this paper, we introduce Gromov-Hausdorff (GH) and Kolmogorov-Smirnov (KS) distances. GH-distance is often used in persistent homology based brain network models. The superior performance of KS-distance is contrasted against matrix norms and GH-distance in random network simulations with the ground truths...

Persistent left superior vena cava (PLSVC) is a congenital anomaly, that results when there is an absence of the normal regression of the left common precardinal vein during embryogenesis. Usually, this anomaly remains asymptomatic, however, when the PLSVC drains into the left atrium this could lead to a right-to-left shunt. Additionally, this can result in inadvertent delivery of air or thrombus into the systemic circulation with potential neurologic, cardiac and renal complications. In this article, we present a case of an extreme premature Mexican newborn in which the diagnosis was made after placement of a percutaneous central venues catheter...
