Published: June 2018

AbstractObjectiveTo evaluate the efficiency of spermatozoa cryopreservation and to compare the clinical pregnancy outcomes in intracytoplasmic sperm injection (ICSI) using fresh versus cryopreserved spermatozoa collected by testicular sperm aspiration (TESA).MethodsA retrospective study was performed to compare the outcomes of men who accepted frozen‐spermatozoa‐based TESA‐ICSI with those of men who underwent TESA‐ICSI using fresh spermatozoa between January 1, 2015, and December 30, 2016. The groups were matched for age. The rates of fertilization, good‐quality embryos, blastocyst formation, and clinical pregnancy outcomes were obtained from clinical records and were compared between the groups.ResultsThere were no significant differences between the frozen TESA group (n=79) and the fresh TESA group (n=194) in the rates of fertilization (71.4% vs 73.4%), good‐quality embryos (55.3% vs 54.5%), blastocyst formation (60.9% vs 60.1%), clinical pregnancy (61.7% vs 55.1%), and live delivery (51.1% vs 45.7%) (P>0.05 for all comparisons).ConclusionFreezing low‐count sperm collected by TESA with a cryoprotectant was an efficient method in the treatment of male factor infertility.

AbstractWe report a rare case of full neurological recovery in a 77‐year‐old woman with an initial Glasgow Coma Scale of 3 while taking a bedrock bath. Severe heatstroke was quickly diagnosed, and intensive treatment was immediately provided. Laboratory data showed multi‐organ failure, and her electroencephalogram showed very low amplitude, indicating a poor prognosis; however, she gradually recovered consciousness, and her electroencephalogram normalized, showing a Glasgow Coma Scale of 15 at discharge. This case demonstrated that physicians should pay careful attention when withholding treatment from a patient with severe heatstroke accompanied by a poor initial electroencephalogram result and laboratory data.

Published: June 2018

AbstractBACKGROUNDBacteria with 1‐aminocyclopropane‐1‐carboxylate (ACC) deaminase activity could decrease the ethylene level, confer resistance of plant, and stimulate plant growth under biotic and abiotic stress conditions.RESULTSPlant growth‐promoting rhizobacteria (PGPR) strains Enterobacter aerogenes (LJL‐5) and Pseudomonas aeruginosa (LJL‐13) were obtained from the rhizosphere of alfalfa grown under saline‐alkali conditions. The ACC deaminase activity of E. aerogenes (LJL‐5) and Ps. aeruginosa (LJL‐13) was approximately 2−5 µmol mg−1 h−1. indole acetic acid synthesis was increased with the increasing concentration of l‐tryptophan. Siderophore production and phosphate solubilization in Ps. aeruginosa (LJL‐13) were higher than those in E. aerogenes (LJL‐5). Compared to the non‐inoculated seedlings (1.31 ng mL−1 h−1), inoculated alfalfa seedlings with E. aerogenes (LJL‐5) (0.90 ng mL−1 h−1) and Ps. aeruginosa (LJL‐13) (0.78 ng mL−1 h−1) emitted lower levels of ethylene. Under saline‐alkali conditions in the greenhouse, inoculation with E. aerogenes (LJL‐5) and Ps. aeruginosa (LJL‐13) increased the biomass, soil and plant analyzer development (SPAD), and P content of alfalfa plants, and also induced the activity of antioxidant enzymes (superoxide dismutase, peroxidase and catalase), promoted the accumulation of antioxidant substances and removed various harmful substances. Under saline‐alkali conditions in the field (2012, 2013, and 2014), inoculation of alfalfa with E. aerogenes (LJL‐5) and Ps. aeruginosa (LJL‐13) significantly increased the shoot height, fresh and dry weights, yield and crude protein content of alfalfa plants, but decreased the fiber content.CONCLUSIONTwo PGPR strains were isolated from the rhizosphere of alfalfa in saline‐alkali conditions. Both strains could promote alfalfa growth in saline‐alkali soil, and could be used as biofertilizer to promote plant growth under stress and reduce environmental pollution caused by fertilizers simultaneously. © 2018 Society of Chemical Industry
Exploring a Polar Two‐dimensional Multi‐layered Hybrid Perovskite of (C5H11NH3)2(CH3NH3)Pb2I7 for Ultrafast‐Responding Photodetection

Published: June 2018

AbstractAlthough organic‐inorganic hybrid perovskites demonstrate promising potentials for photodetection, one great challenge still to be addressed is their relatively low responding speed (often at the magnitude order of ∼ms). Herein, a solution‐processed photodetector based on polar two‐dimensional (2D) multilayered hybrid perovskite crystal is fabricated, (C5H11NH3)2(CH3NH3)Pb2I7 (EMA, where C5H11NH3+ is n‐pentylaminium), which exhibits an ultrafast responding time of ≈1.52 μs. This figure‐of‐merit is faster at least by 2–4 orders than other reported 2D organic‐inorganic hybrid perovskite photodetectors. To the best of knowledge, this is the record‐fast response‐speed for lateral‐type devices of 2D organic‐inorganic hybrid perovskite. Such ultrafast responding can be attributed to the high crystallinity and quite low density of defects and traps. In addition, this device also presents a high photocurrent on/off ratio (>103) and extremely low dark current (≈10−10 A), indicating its potential applications for high‐efficiency photodetectors. Our results pave the pathway toward ultrafast responding photodetection of 2D organic‐inorganic hybrid perovskites.
Dynamic Monte Carlo Simulation of Olefin Block Copolymers (OBCs) Produced via Chain‐Shuttling Polymerization: Effect of Kinetic Rate Constants on Chain Microstructure

Published: June 2018

AbstractOlefin block copolymers (OBCs) are thermoplastic elastomers with unique statistical multiblock structures produced by chain‐shuttling polymerization. In this study, a dynamic Monte Carlo model is used to simulate the effect of changing chain‐shuttling (kCS), catalyst deactivation (kd), and chain transfer (ktr) rate constants on the microstructure of OBCs made in a semi‐batch reactor. The simulations show how each rate constant governs different aspects of the OBC chains and provide guidelines on how to fine‐tune OBC microstructure to achieve precisely designed multiblock structures.

Evidence for Cogradient Growth and Survival Between Two Geographically Distinct Stocks of Muskellunge

Published: June 2018

Abstract
Intraspecific genetic variation across the distribution of Muskellunge Esox masquinongy suggests the existence of divergent stocks among major river drainages. Often, stocks differentiate in response to latitudinal variation in thermal regime. Genetic variation and thermal adaptation may drive fish to either maximize growth during brief growing seasons at higher latitudes (counter-gradient growth) or experience longer periods of slower growth at lower latitudes (cogradient growth). The strength and direction of these genetic effects matter for fish stocked outside of their native drainage and for populations experiencing changes to regional thermal regimes. We used a replicated pond experiment with uniform initial fish size and environmental conditions to compare the survival and growth of stocked age-0 Ohio River drainage (OH) Muskellunge with those of the more northerly upper Mississippi River drainage (MISS) stock following their first winter and a year after introduction into a common environment. Both stocks had similarly high winter survival, though the MISS stock had a slower growth rate overwinter than the OH stock. Survival during the latter spring-to-fall period was greatly reduced for the MISS stock, however, with the differences in growth rate persisting. These findings suggest that cogradient adaptation to temperatures experienced during early life stages in native environments results in a disadvantage for high-latitude stocks of Muskellunge in thermal regimes warmer than those they have historically experienced in their native drainages.

Published: June 2018

AbstractBackgroundThe median age of patients with Ewing sarcoma (EwS) at diagnosis is around 14–15 years. Older age is associated with a worse outcome. The correlation of age at diagnosis on sites of disease has not been fully described.ObjectiveThe goal of this study was to evaluate the differences in sites of primary tumor and metastatic tumor involvement according to age groups.Design/methodEwS data from the Gesellschaft für Pädiatrische Onkologie und Hämatology (GPOH) database of the Cooperative Ewing Sarcoma Study (CESS) 81/86 and the European Intergroup Cooperative Ewing's Sarcoma Study EICESS 92 and the EUROpean Ewing tumor Working Initiative of National Groups‐99‐Protocol (EURO‐E.W.I.N.G.‐99) study were analyzed. Patient and tumor characteristics were evaluated statistically using chi square tests.ResultsThe study population included 2,635 patients with bone EwS. Sites of primary and metastatic tumors differed according to the age groups of young children (0–9 years), early adolescence (10–14 years), late adolescence (15–19 years), young adults (20–24 years), and adults (more than 24 years). Young children demonstrated the most striking differences in site of disease with a lower proportion of pelvic primary and axial tumors. They presented less often with metastatic disease at diagnosis.ConclusionsSite of primary and metastatic tumor involvement in EwS differs according to patient age. The biological and developmental etiology for these differences requires further investigations.

Published: June 2018

AbstractBackgroundVaso‐occlusive crisis (VOC) is frequent in children with sickle cell disease (SCD) creating significant burden on patients, families, and emergency departments (ED). The objective of the project was to reduce the admission rate for children with SCD presenting to our ED with VOC by >20% within 6 months of initiating individualized pain plans (IPP).MethodsA multi‐disciplinary quality improvement team was assembled. A Plan‐Do‐Study‐Act (PDSA) format was employed. The IPP document was created in a unique folder within the electronic medical record. IPPs were created through retrospective chart review for our 80 highest resource users. Pediatric residents, ED residents, and ED attending physicians were instructed on use of the IPPs. Our study measured the presence of an IPP, adherence to the IPP, and time to opiate administration. Our primary outcome was admission rate. Length of stay and 72‐hr return to the ED were assessed as balancing measures.ResultsOverall, admission rate decreased by 24% following implementation compared with the previous 5 years (P = 0.046). IPPs were created for 78% of patients and followed by ED staff in 86% of visits. Admission rate was significantly lower for patients receiving a second opiate dose within 45 min of the first dose (P < 0.01). There was no difference in readmission rate or 72‐hr return rate to ED.ConclusionsThis study presents an effective strategy to reduce admission rate for children with SCD presenting with VOC. Shorter time to second opiate dosing was also associated with reduced risk of admission.

Published: June 2018

AbstractThe cheap, environment‐friendly and renewable biomass is a promising raw material to prepare the carbon‐based composites for the lithium‐ion batteries. Herein, the loofah sponge‐derived hollow carbon fibers (LDHCF) were obtained by the activation and carbonization process of biomass loofah sponges. The LDHCF with the porous structure shows the high surface area and active sites. When LDHCF were coated with SnO2 nanoparticles via the hydrothermal method, the SnO2/LDHCF composite as anode material exhibits a reversible capacity of 562.1 mAh g−1 at 0.2 A g−1 after 100 cycles and the columbic efficiency is 99.0% due to the good conductivity, buffer effect of LDHCF, and high theoretical specific capacity of SnO2. Such the structure not only proves a novel high‐quality carbon template/matrix, but also provides a preferable way to make sustainable anodes in electrochemical energy storage and economical multi‐functional carbon‐based hybrids available for other practical applications.

AbstractA proof‐of‐concept for the fabrication of genetically customizable biogenic materials for photovoltaic applications is presented. E. coli is first genetically engineered to heterologously express the carotenoid biosynthetic pathway from plants. This modification yields a strain that overproduces the photoactive pigment lycopene. The pigment‐producing cells are then coated with TiO2 nanoparticles via a tryptophan‐mediated supramolecular interface, and subsequent incorporation of the resulting biogenic material (cells@TiO2) as an anode in an I−/I3−‐based dye‐sensitized solar cell yields an excellent photovoltaic (PV) response. This work lays strong foundations for the development of bio‐PV materials and next‐generation organic optoelectronics that are green, inexpensive, and easy to manufacture.

Published: June 2018

Abstractβ‐Cyclodextrin is cyclic oligosaccharide possessing hydrophobic cavity, which binds the substrates selectively and catalyze number of organic transformations with high selectivity. It catalyzes the reaction by non‐covalent supramolecular bonding with reversible formation of host‐guest complexes as seen in enzymes. This account summarizes our efforts in designing a good number of important organic transformations using β‐cyclodextrin and its derivatives. These reactions were performed in neat, aqueous as well as organic media. Greener synthetic routes to a variety of biologically relevant organic molecules has been developed. The temperature, solvent and catalyst amount plays in important role in these reactions. β‐Cyclodextrin activates variety of organic compounds like aldehydes, ketones, anhydride, oximes, amines, nitriles and increases the rate of reactions.

Published: June 2018

AbstractNormal values for intraocular pressure (IOP) and tear production in conscious cervids have not been reported to date. Based on trends in zoological institutions to perform non‐anaesthetized health exams, it is applicable to establish normal values in conscious animals, as anaesthesia and sedation can alter these parameters. The goal of this study was to estimate intraocular pressures using rebound tonometry and measure tear production values in a group of healthy, conscious, European fallow deer utilizing chute restraint. Evaluation of these values with regards to instrumentation and restraint variables will be assessed. Complete ophthalmic examinations, including estimation of IOP with rebound tonometry and measurement of tear production with Schirmer tear tests (STT) were performed on nine conscious European fallow deer (Dama dama) restrained in a chute. Correlations between IOP on the unspecified (P) and the equine (H) settings, as well as IOP and STT differences between left (OS) and right (OD) eyes were evaluated, in addition to assessment of correlations between right and left lateral recumbency on IOP and STT. Tear production measurements were 18.7 ± 5.1 mm min−1 with a 95% confidence interval (CI) range of 16.4–21.1 mm min−1. Intraocular pressure measurements for the P setting were 16.1 ± 4.5 mmHg with a 95% CI range of 14.1–18.2 mmHg, and for the H setting were 21.5 ± 5.1 mmHg with a 95% CI range of 19.1–23.9 mmHg. No statistically significant difference (P > 0.05) was found between OS and OD in any test. Neither left nor right lateral recumbency was found to have a statistically significant effect on IOP or STT. This study represents the first assessment of ophthalmic parameters in conscious fallow deer with rebound tonometry and STT.
