Critical Role of Simultaneous Reduction of Atmospheric Odd Oxygen for Winter Haze Mitigation.

The lockdown due to COVID-19 created a rare opportunity to examine the nonlinear responses of secondary aerosols, which are formed through atmospheric oxidation of gaseous precursors, to intensive precursor emission reductions. Based on unique observational data sets from six supersites in eastern China during 2019-2021, we found that the lockdown caused considerable decreases (32-61%) in different secondary aerosol components in the study region because of similar-degree precursor reductions. However, due to insufficient combustion-related volatile organic compound (VOC) reduction, odd oxygen (O = O + NO) concentration, an indicator of the extent of photochemical processing, showed little change and did not promote more decreases in secondary aerosols.

Biomass-burning emissions could significantly enhance the atmospheric oxidizing capacity in continental air pollution.

Volatile organic compounds (VOCs) are important precursors of photochemical pollution. However, a substantial fraction of VOCs, namely, oxygenated VOCs (OVOCs), have not been sufficiently characterized to evaluate their sources in air pollution in China. In this study, a total of 119 VOCs, including 60 OVOCs in particular, were monitored to provide a more comprehensive picture based on different online measurement techniques, proton-transfer-reaction time-of-flight mass spectrometry (PTR-ToF-MS) and online gas chromatography/mass spectrometry (GC/MS), at a receptor site in southeastern China during a photochemically active period.

The first mitogenome of Lesser Whitethroat, Ticehurst & Whistler, 1933 (Passeriformes: Sylviidae) and its phylogenetic implications for the genus .

The complete mitogenome of the Lesser Whitethroat, Ticehurst & Whistler, 1933 was determined, which belongs to Sylviidae, Passeriformes. The mitogenome had a length of 17,959 bp and consisted of 37 genes including 13 PCGs, 2 ribosomal RNAs (rRNA) genes, and 22 transfer RNAs (tRNA) genes. In addition, two control regions (CRs) were also existed in the mitogenome, with Sylvioidea typcial gene arrangement of cytb-trnT-CR1-trnP-nad6-trnE-CR2-trnF-rrnS.

Reverse contralateral proximal tibial plating and cannulated screws fixation for Hoffa fracture: A case report.

Hoffa fracture is a rare type of distal femoral fracture occurs in the coronal plane of either femoral epicondyle. To date, screws in combination with lateral plate fixation is widely accepted to achieve stable fixation and good results. However, up to now there has not been a specially designed anatomical plate for lateral fixation of Hoffa fracture.

Exploration of sources of OVOCs in various atmospheres in southern China.

Oxygenated volatile organic compounds (OVOCs) are critical atmospheric ozone and secondary organic aerosol (SOA) precursors and radical sources, while understanding of OVOC sources in the atmosphere, especially with large anthropogenic emissions, still has large uncertainties. A high-sensitivity proton transfer reaction mass spectrometer (PTR-MS) was deployed in vastly different atmospheres in southern China, including an urban site (SZ-U), a regional site (NA-R), and a background site (NL-B). Four critical OVOCs, i.

Phylogenetic relationships of Scelimeninae genera (Orthoptera: Tetrigoidea) based on COI, 16S rRNA and 18S rRNA gene sequences.

Scelimeninae is an important subfamily of Tetrigoidea; however, the phylogenetic relationships within Scelimeninae are poorly understood, and its generic classification has remained unstable. In this study, the COI, 16S rRNA and 18S rRNA genes from 24 species in 9 genera within Scelimeninae were amplified and sequenced, the base composition and inter-species genetic distance of the combined sequence of COI, 16S rRNA and 18S rRNA genes were analyzed, and the molecular phylogenetic relationships were reconstructed using Maximum Likelihood (ML) and Bayesian inference (BI) methods. The results of sequence analysis showed that the total length of the combined COI, 16S rRNA and 18S rRNA gene sequence was 3507 bp, including 2345 conservative sites, 1144 variable sites and 901 parsimony-informative sites.

Mitochondrial genomes of three Tetrigoidea species and phylogeny of Tetrigoidea.

The mitochondrial genomes (mitogenomes) of , and (Orthoptera: Caelifera: Tetrigoidea) were sequenced in this study, and almost the entire mitogenomes of these species were determined. The mitogenome sequences obtained for the three species were 15,180, 14,495 and 14,538 bp in length, respectively, and each sequence included 13 protein-coding genes (PCGs), partial sequences of rRNA genes (rRNAs), tRNA genes (tRNAs) and a A + T-rich region. The order and orientation of the gene arrangement pattern were identical to that of most Tetrigoidea species.

Mitochondrial Genomes of Two Pygmy Grasshoppers (Orthoptera: Tetrigoidea) and a Comparative Analysis of Caelifera Mitogenomes.

The nearly complete mitogenomes of Bolivaritettix sikkinensis and Bolivaritettix yuanbaoshanensis were determined and compared with the mitogenomes of other 29 caeliferans. These two newly determined mitogenomes displayed the typical gene organization and composition, codon usage and AT skew of most Caelifera mitogenomes. A comparison of 31 orthopteran sequences revealed that the main causes of the differences in total length are an A+T-rich region and the length of IGS, even the rRNAs, and an AT content proportional to the value of AT-skew in the third position of PCGs.

Complete mitochondrial genome of (Galliformes: Phasianidae).

The complete mitochondrial genome (mitogenome) of , consisting of 16,693 bp, was determined and analyzed.

The phylogenetic relationships of 25 Phasianidae species and three Odontophoridae species as outgroup using maximum likelihood and Bayesian inference methods based on a concatenated dataset from mitogenomes were analyzed.
