Oxidative Dehydrogenation of Ethylbenzene into Styrene by Fe-Graphitic Catalysts.

Carbon-based catalysts have attracted much attention for the dehydrogenation (DH) of organic molecules, due to their rich active sites, high conversion efficiency, and selectivity. However, because of their poor stability at high operation temperature and relatively high cost, their practical applications have been limited. Here, we report a simple ball-milling-induced mechanochemical reaction which can introduce iron (Fe) and different functional groups (mostly stable aromatic C═O after heat-treatment) along the edges of graphitic nanoplatelets.

Effects of laser-assisted thinning versus opening on clinical outcomes according to maternal age in patients with repeated implantation failure.

Laser-assisted thinning (LAT) and laser-assisted opening (LAO) are performed as part of human in vitro fertilization (IVF) to increase the implantation rate in patients with a poor prognosis and in cases of repeated implantation failure. However, an insufficient number of studies have directly compared LAT and LAO using the same methods. Therefore, we compared the effects of LAT and LAO on clinical outcomes according to maternal age in patients with repeated implantation failure.

Encapsulating Iridium Nanoparticles Inside a 3D Cage-Like Organic Network as an Efficient and Durable Catalyst for the Hydrogen Evolution Reaction.

Developing efficient and durable electrocatalysts is key to optimizing the electrocatalytic hydrogen evolution reaction (HER), currently one of the cleanest and most sustainable routes for producing hydrogen. Here, a unique and efficient approach to fabricate and embed uniformly dispersed Ir nanoparticles in a 3D cage-like organic network (CON) structure is reported. These uniformly trapped Ir nanoparticles within the 3D CON (Ir@CON) effectively catalyze the HER process.

Direct Synthesis of a Covalent Triazine-Based Framework from Aromatic Amides.

There have been extensive efforts to synthesize crystalline covalent triazine-based frameworks (CTFs) for practical applications and to realize their potential. The phosphorus pentoxide (P O )-catalyzed direct condensation of aromatic amide instead of aromatic nitrile to form triazine rings. P O -catalyzed condensation was applied on terephthalamide to construct a covalent triazine-based framework (pCTF-1).

A Randomized, Double-blind, Active-controlled Clinical Trial of a Cell Culture-derived Inactivated Trivalent Influenza Vaccine (NBP607) in Healthy Children 6 Months Through 18 Years of Age.

Background: Although a number of cell culture-derived influenza vaccines have been approved for use in adults, there have been few clinical trials of cell culture-derived seasonal influenza vaccines for young children.

Methods: We conducted a randomized, double-blind phase III clinical trial to evaluate the safety and immunogenicity of a cell culture-derived subunit trivalent inactivated influenza vaccine (NBP607, SK Chemicals Co., Ltd.

Forming a three-dimensional porous organic network via solid-state explosion of organic single crystals.

Solid-state reaction of organic molecules holds a considerable advantage over liquid-phase processes in the manufacturing industry. However, the research progress in exploring this benefit is largely staggering, which leaves few liquid-phase systems to work with. Here, we show a synthetic protocol for the formation of a three-dimensional porous organic network via solid-state explosion of organic single crystals.

Efficacy of embryo transfer on day 2 versus day 3 according to maternal age in patients with normal ovarian response.

Objective: Delaying embryo transfer (ET) enables us to select among the embryos available for transfer and is associated with positive effects on implantation and pregnancy outcomes. However, the optimal day for ET of human cleavage-stage embryos remains controversial.

Methods: A retrospective study of 3,124 fertilization/intracytoplasmic sperm injection cycles (2,440 patients) was conducted.

Seroprevalence of Antibodies to Toxocara Species in the United States and Associated Risk Factors, 2011-2014.

Background: Toxocariasis results from infection with larval stages of a dog and cat intestinal nematode and causes human morbidity. The current United States estimate of Toxocara exposure is 13.9% (National Health and Nutrition Examination Survey [NHANES] III [1988-1994]).

Long Cut Straw Provides Stable the Rates of Survival, Pregnancy and Live Birth for Vitrification of Human Blasotcysts.

Most of the commercial devices for vitrification are directly immersed into the warming solution (WS) for increasing of warming rate. However, the previous modified cut standard straw (MCS) which has reported is difficult to immerse into the WS. The aim of this study was to investigate whether the long cut straw (LCS) could be useful as a stable tool for vitrified-warmed human blastocysts.

Development of Two FhSAP2 Recombinant-Based Assays for Immunodiagnosis of Human Chronic Fascioliasis.

In the United States, infection with Fasciola hepatica has been identified as an emerging disease, primarily in immigrants, refugees, and travelers. The laboratory test of choice for diagnosis of fascioliasis is detection of disease specific antibodies, most commonly uses excretory-secretory antigens for detection of IgG antibodies. Recently, recombinant proteins such as F.

Development of Ss-NIE-1 recombinant antigen based assays for immunodiagnosis of strongyloidiasis.

Strongyloides stercoralis is a widely distributed parasite that infects 30 to 100 million people worldwide. In the United States strongyloidiasis is recognized as an important infection in immigrants and refugees. Public health and commercial reference laboratories need a simple and reliable method for diagnosis of strongyloidiasis to identify and treat cases and to prevent transmission.

Pepper, chili (Capsicum annuum).

Pepper is a recalcitrant plant for Agrobacterium-mediated genetic transformation. Several obstacles to genetic transformation remain such as extremely low transformation rates; the choice of correct genotype is critical; and there is a high frequency of false positives due to direct shoot formation. Here, we report a useful protocol with a suitable selection method.

Detection of transgene in early developmental stage by GFP monitoring enhances the efficiency of genetic transformation of pepper.

In order to establish a reliable and highly efficient method for genetic transformation of pepper, a monitoring system featuring GFP (green fluorescent protein) as a report marker was applied to Agrobacterium-mediated transformation. A callus-induced transformation (CIT) system was used to transform the GFP gene. GFP expression was observed in all tissues of T(0), T(1) and T(2) peppers, constituting the first instance in which the whole pepper plant has exhibited GFP fluorescence.

Additional role of urine output criterion in defining acute kidney injury.

Background: Diagnosis of acute kidney injury (AKI) has been a major concern due to its association with increased morbidity and mortality. However, the clinical implication of the urine output criterion (UOCr) in diagnosing AKI has not been fully established.

Methods: We assessed the incidence of AKI among 1625 critically ill patients and analysed the overall survival rates based on the serum creatinine criterion (CrCr) and UOCr, both of which have been defined by the AKI Network (AKIN).

Transgenic peppers that are highly tolerant to a new CMV pathotype.

The CMV (cucumber mosaic virus) is the most frequently occurring virus in chili pepper farms. A variety of peppers that are resistant to CMVP0 were developed in the middle of 1990s through a breeding program, and commercial cultivars have since been able to control the spread of CMVP0. However, a new pathotype (CMVP1) that breaks the resistance of CMVP0-resistant peppers has recently appeared and caused a heavy loss in productivity.

Comparison of polymerase chain reaction and the indirect particle agglutination antibody test for the diagnosis of Mycoplasma pneumoniae pneumonia in children during two outbreaks.

Background: Diagnosis of Mycoplasma pneumoniae pneumonia is challenging because of the lack of standardized rapid tests. Many serologic tests and polymerase chain reaction (PCR) based methods are used with different diagnostic criteria.

Methods: This retrospective study was conducted to compare the diagnostic values of the indirect particle agglutination test and nested PCR of nasopharyngeal aspirates for the diagnosis of M.
