To enrich the genomic database of Catantopinae (Orthoptera: Acrididae), mitogenomes of three species from different genera, Traulia nigritibialis (15,701 bp), Choroedocus capensis (16,293 bp) and Stenocatantops splendens (15,574 bp), were characterized and compared with those of other grasshoppers in the subfamily. All 13 protein-coding genes (PCGs) were initiated by ATN codons except COI with ACC (C. capensis and S.splendens) and ND6 with TTG (S. splendens). All transfer RNA (tRNA) genes had a typical clover-leaf structure, except tRNASer(AGN) in which the base pairs of the dihydrouridine (DHU) arm were reduced. The phylogenetic relationships were constructed among 22 species from four subfamiles of Acrididae by classical classifications based on two datasets of their mitogenomes using both Bayesian Inference (BI) and Maximum Likelihood (ML). The phylogenetic analysis confirmed the monophyly of the three other subfamilies, but did not provided support of the monophyly of Catantopinae.

Black carbon (BC) is important due to its complex influences on the environment and on climate in particular. However, reported BC data are largely dependent on measurement techniques due to the multitude of measurement principles. Here we focused on thermal-optical method which has been widely used to determine BC mass (as elemental carbon, EC). Several factors influencing EC measurement were investigated. Results from source samples representing vehicle engine emissions pointed to a continuum of EC components in thermal stability and provided direct observational evidence for the premature evolution of EC in inert atmosphere. It was also found that EC masses may be substantially underestimated for the vehicle exhaust samples if the adopted protocol requires an oxidizing atmosphere to define the split point between organic carbon (OC) and EC. Results from a field campaign conducted during winter in Beijing showed that the optical attenuation (ATN; i.e., the filter transmittance signal, I) was largely saturated for the samples with relatively high loadings, indicating their EC results were unreliable. Improved measurement of EC was achieved by extracting these heavily loaded filters using methanol, given that ATN was considerably reduced by the extraction and, moreover, saturation of ATN (or I) became not evident for the extracted samples. The methanol extraction also significantly reduced the transformation of OC to char-OC, by removing the majority (i.e., ~85%) of the deposited organic aerosols. Higher EC were measured for the extracted samples compared with the untreated ones, indicating that EC tends to be underestimated due to the charring-induced uncertainties. In addition, the methanol extraction largely reduced the inter-protocol discrepancy in the EC measurement results. Similar effects of methanol extraction have been observed during summer in Beijing, despite the seasonal variations of aerosol sources and compositions. This study indicates the potential benefits of methanol extraction for EC measurement.

This paper discusses multi-spectroscopic and molecular docking analysis of the interaction between atenolol (ATN) and deoxyribose nucleic acid (DNA) using alizarin (ALZ) as a spectroscopic probe. ATN is a β1 -receptor antagonist belonging to the β-blocker class of molecules. Experimental findings that were based on different spectroscopic analysis, melting studies, viscometric analysis, 1 H nuclear magnetic resonance and circular dichroism studies revealed the presence of a grove-binding mode. The effect of ionic strength was also studied, and observations suggested that electrostatic interaction also played a minor role during interaction. Molecular docking analysis suggested that the dominant force for the grove-binding phenomenon was hydrogen bonding between the 24-H residue of ATN and O of the 10-G residue, and the 40-H residue of ATN and N of the 17-A base residue. Competitive binding study of the ALZ-DNA complex with ATN showed that, despite an increase in the amount of ATN in the ALZ-DNA complex, the overall absorbance remained unchanged. The decrease in fluorescence in the ALZ-DNA system may be due to new non-fluorescent ATN-DNA-ALZ complex formation.

Contrast-induced acute kidney injury, also called contrast-induced nephropathy, is one of the main causes of acute renal failure/acute kidney injury (AKI) in hospitalized patients within 48 to 72 hours of contrast media administration during various radiologic procedures. Several factors can be responsible for contrast-induced acute tubular necrosis (ATN); however, patient and procedure-related factors play the lead role in determining the development of contrast-induced nephropathy. There is no definitive treatment and hydration remains the mainstay preventive strategy. This article will review the incidence, criteria for definitive diagnosis, and an effective approach on how to prevent contrast-induced nephropathy in a clinical setup.

This study determined the first complete mitochondrial genome (mitogenome) of a stonefly, Scopura longa (Plecoptera: Scopuridae), and reconstructed a phylogeny based on two datasets of mitogenomes in eighteen available stoneflies to examine the relationships among Plecoptera. The complete mitogenome of S. longa is a circular molecule of 15,798bp in size. It contains 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs) and a control region (CR). Most PCGs used standard ATN start codons and TAN stop codons. All tRNAs could be folded as typical cloverleaf secondary structures except tRNASer(AGN), with the dihydrouridine (DHU) arm missing. Tandem repeat regions, two potential stem-loop (SL) structures, Poly T structures and G+C-rich regions are detected in the control region. Finally, the phylogenetic relationships among the families within the Arctoperlaria were reconstructed. The topological structures of the two trees were almost identical. The present phylogenetic analysis shows that S. longa belongs to the infraorder Euholognatha. The monophyly of each family is generally well supported based on nucleotide sequences. The Pteronarcyidae is sister to ((Peltoperlidae+Styloperlidae)+(Perlidae+(Perlodidae+Chloroperlidae))).

This study aimed to clarify intersection patterns and points among the superficial temporal artery (STA), superficial temporal vein (STV), and auriculotemporal nerve (ATN) based on surface anatomical landmarks to provide useful anatomical information for surgical decompression treatments of migraine headaches in Asians. Thirty-eight hemifaces were dissected. The positional patterns among the ATN, STA, and STV were divided into three morphological types. In type I, the ATN ran toward the temporal region and superficially intersected the STA and STV (n = 32, 84.2%). In type II, the ATN ran toward the temporal region and deeply intersected the STA and STV (n = 4, 10.5%). In type III, the ATN ran toward the temporal region and deeply intersected the STV alone (n = 2, 5.3%). The intersection points of types II and III were 10.3 ± 5.6 mm (mean ± SD) and 10.4 ± 6.1 mm anterior and 42.1 ± 21.6 mm and 41.4 ± 18.7 mm superior to the tragus, respectively. The ATN superficially intersected the STA and STV in all the Korean cadaver, while the ATN deeply intersected the STA and STV in 15% of the Thai cadavers. The pattern of the ATN deeply intersecting the STA and STV was less common in present Asian populations than in previously-reported Caucasian populations, implying that migraine headaches (resulting from the STA and STV compressing the ATN) are less common in Asians.

- RDRes Dev Disabil 2018; 83:270-279
- CONCLUSIONS: Among children with ASD aggressive behavior independently predicts sleep problems. The model's high sensitivity for identifying children at risk and its accurate prediction of low risk can help with treatment and prevention of sleep problems. Further data collection may provide better prediction through methods requiring larger samples.
