The presence of personal care products (PCPs) in the marine environment is of major concern. PCPs, UV filters, and musks can enter the marine environment indirectly through wastewater or directly via recreational activities. We conducted this study to document patterns in the occurrence of seven PCPs at three coastal sites impacted by recreational activities during 1 day. The study focused on diurnal variations in these seven PCPs in seawater and indigenous mussels. In seawater, UV filters showed diurnal variations that mirrored variations in recreational activities at the sites...

Forest musk deer (Moschus berezovskii; FMD) are both economically valuable and highly endangered. A problem for FMD captive breeding programs has been the susceptibility of FMD to abscesses. To investigate the mechanisms of abscess development in FMD, the blood transcriptomes of three purulent and three healthy individuals were generated. A total of ~39.68 Gb bases were generated using Illumina HiSeq 4000 sequencing technology and 77,752 unigenes were identified after assembling. All the unigenes were annotated, with 63,531 (81...

The Chinese forest musk deer (Moschus berezovskii Flerov) is an endangered artiodactyl mammal. The musk secreted by sexually mature males is highly valued for alleged pharmaceutical properties and perfume manufacturing. However, the genomic and transcriptomic resources of musk deer remain deficiently represented and poorly understood. Next-generation sequencing technique is an efficient method for generating an enormous amount of sequence data that can represent a large number of genes and their expression levels...

Muscle specific kinase (MuSK) myasthenia gravis (MG, MuSK-MG) is a rare subgroup of MG affecting mainly women during childbearing years. We investigated the influence of pregnancy in the course of MuSK-MG and pregnancy outcomes in females with MuSK-MG. A multicentre cohort of 17 women with MuSK-MG was studied retrospectively; 13 of them with ≥1 pregnancy. MuSK-MG onset age was 35,4 years; 23,0% had other autoimmune disorder; 46,2% were treatment refractory. Thirteen women experienced 27 pregnancies, either after MG onset (group I) (n = 4; maternal age at conception = 29...

Seronegative myasthenia gravis (MG) is a generalized form of MG that is diagnosed on the basis of clinical symptoms, electrophysiological testing, and pharmacological responses, in the absence of a seropositive status for anti-acetylcholine receptor (AChR) antibodies. Generalized MG that is seronegative for anti-AChR, anti-muscle-specific kinase (MuSK), and anti-low density lipoprotein receptor related protein 4 (Lrp4) antibodies is known as triple-seronegative MG. We here describe a case of triple-seronegative MG in an 8-year-old boy...

Klebsiella pneumoniae is an important pathogen commonly associated with opportunistic infections. In this study, lung pathogenic K. pneumoniae (LPKP) was isolated and identified from suppurative pneumoniae in forest musk deer by conventional methods and by 16S ribosomal RNA sequence analysis. Median lethal dose and histopathologic analysis were used to demonstrate pathogenicity of the organism in mice. Furthermore, a draft genome of LPKP was sequenced, and its virulence genes were detected. One hundred and twenty-two virulence genes encoded determinant of capsule polysaccharide (CPS), lipopolysaccharide, fimbriae, outer membrane proteins, iron acquisition, and urease...

Polycyclic musks (PCMs) in the aquatic environment have become an emerging environmental issue because of their potential risk. The most commonly used method for analysis of PCMs is gas chromatography-mass spectrometer (GC-MS) with different sample extractions, which are somewhat expensive to operate, laborious and complex. In this paper, a carbon nanotube-enhanced real time immuno-PCR was developed for ultrasensitive detection of AHTN in water for the first time. The SWCNTs were used to immobilize numerous amino-DNA and polyclonal antibody to form polyclonal antibody-CNTs-DNA conjugates, which were used as a signal-amplifier in the proposed immunoassay system...

We report the development of a new Spray-drying and Nanoparticle Assembly Process (SNAP), that enables the formation of stable, yet rapidly dissolving, sub-200 nm nano-crystalline particles within a high Tg glassy matrix. SNAP expands the class of drugs that Spray Dried Dispersion (SDD) processing can address to encompass highly crystalline, but modestly hydrophobic drugs that are difficult to process by conventional SDD. The process integrates rapid precipitation and spray drying within a custom designed nozzle to produce high supersaturations and precipitation of the drug and high Tg glassy polymer...

BACKGROUND: Laparoscopic donor nephrectomy has become the standard of care due to multiple benefits. Currently, there are various techniques employed with two different approaches: transperitoneal (TLDN) or retroperitoneoscopic (RLDN) approach. There is a lack of data to determine which technique is superior, although the RLDN offers an anatomical advantage by avoidance of manipulation of the intraperitoneal organs. The aims of this study were to explore the merits of RLDN to TLDN and assess the learning curve of transition from TLDN to RLDN...
