H7N9 virus has caused five infection waves since it emerged in 2013. The highest number of human cases was seen in Wave Five; however, the underlying reasons have not been thoroughly elucidated. In this study, the geographical distribution, phylogeny and genetic evolution of 240 H7N9 viruses in Wave Five, including 35 new isolates from patients and poultry in nine provinces, were comprehensively analyzed together with strains from first four waves. Geographical distribution analysis displayed the newly-emerging highly pathogenic (HP) and low pathogenic (LP) H7N9 viruses were co-circulating, causing human and poultry infections across China...

The assessment of forest ecosystem services can quantify the impact of these services on human life and is the main basis for formulating a standard of compensation for these services. Moreover, the calculation of the indirect value of forest ecosystem services should not be ignored, as has been the case in some previous publications. A low compensation standard and the lack of a dynamic coordination mechanism are the main problems existing in compensation implementation. Using comparison and analysis, this paper employed accounting for both the costs and benefits of various alternatives...

Macroion-droplet interactions play a critical role in many settings such as ionization techniques of samples in mass spectrometry analysis and atmospheric aerosols. The droplets under investigation are composed of a polar solvent, primarily water, a charged macroion and, possibly, buffer ions. We present highlights of our research on the relation between the charge state of a macroion and the droplet morphologies. We have determined that depending on the charge on the macroion and certain macroscopic properties of the solvent, such as its dielectric constant and surface tension, a droplet may obtain striking conformations such as droplets with extruded tails, ``pearl-necklace'' conformations and multi-point ``star'' shapes...

Millions of companion animals are relinquished to shelters each year. For each dog entering, their characteristics and the characteristics of the shelter holding him/her influence their time to adoption. Using a Cox proportional hazards frailty model, these issues were explored using data from 31 shelters within the British Columbia Society for the Prevention of Cruelty to Animals shelter system. Results indicated that surrender reason, age, original source, coat color, breed, human population density of the shelter location, and year the nonhuman animal entered the shelter significantly influenced time to adoption...

Toll receptors are involved in innate immunity of invertebrates. In this study, we identify and characterize two Toll genes (named HcToll4 and HcToll5 ) from triangle sail mussel Hyriopsis cumingii. HcToll4 has complete cDNA sequence of 3,162 bp and encodes a protein of 909 amino acids. HcToll5 cDNA is 4,501 bp in length and encodes a protein of 924 amino acids. Both deduced HcToll4 and HcToll5 protein contain signal peptide, extracellular leucine rich repeats (LRRs), and intracellular Toll/interleukin-1 (IL-1) receptor domains...

BACKGROUND: Unicompartmental knee arthroplasty is a successful treatment for unicompartmental knee osteoarthritis that has lower complication rates, faster recovery, and a more natural feeling knee compared to total knee arthroplasty. However, long-term survival has been a persistent concern. As more surgeon-controlled variables have been linked to survival, interest in robotic-assisted surgery has continued to grow. Robotic-assisted surgery has demonstrated the ability. METHODS: A review and synthesis of the literature on the subject of robotic-assisted unicompartmental knee arthroplasty was performed...

Achieving an osseous fusion across the lumbosacral spine is still challenging in spine surgery. For the long multisegmental fusion surgery, it is crucial to build a robust and substantial foundation, which sometimes necessitates the distal spinal fixation to the pelvis. The pelvic fixation technique involves advancing the screw through the alar, thereby providing more purchase across the sacroiliac joint and into the ilium. The S2 alar iliac screws can obtain immediate stability and proper biomechanical strength of constructs...

After a stroke, patients frequently show compromised swallowing, mastication, and speech, as well as unfavorable motion and deviation of the tongue and mandible. The dentist can improve the oral rehabilitation of a patient with deteriorated facial and oral muscles after a stroke by incorporating orofacial myofunctional therapy. This report describes a method for tongue exercises and correction of mandible deviation in an edentulous patient after a stroke by using a pearl on a wire in the anteriomedian palatal part of the maxillary denture...

Abdominal wall defects range from the mild umbilical cord hernia to the highly complex limb-body wall syndrome. The most common defects are gastroschisis and omphalocele, and the rarer ones include the exstrophy complex, pentalogy of Cantrell and limb-body wall syndrome. Although all have a common feature of viscera herniation through a defect in the anterior body wall, their imaging features and, more important, postnatal management, differ widely. Correct diagnosis of each entity is imperative in order to achieve appropriate and accurate prenatal counseling and postnatal management...

Bacterioplankton are the major driving force for biogeochemical cycles in estuarine ecosystems, but the communities that mediate these processes are largely unexplored. We sampled in the Pearl River Estuary (PRE) to examine potential differences in the taxonomic composition of resident (DNA-based) and active (RNA-based) bacterioplankton communities in free-living and particle-associated fractions. MiSeq sequencing data showed that the overall bacterial diversity in particle-associated fractions was higher than in free-living communities...

A novel model named random-forest-spatiotemporal-kriging (RF-STK) was developed to estimate the daily ambient NO2 concentrations across China during 2013-2016 based on the satellite retrievals and geographic covariates. The RF-STK model showed good prediction performance, with cross-validation R2=0.62 (RMSE=13.3 µg/m3) for daily and R2=0.73 (RMSE=6.5 µg/m3) for spatial predictions. The nationwide population-weighted multiyear average of NO2 was predicted to be 30.9±11.7 µg/m3 (mean±standard deviation), with a slowly but significantly decreasing trend at a rate of -0...

Basilar invagination is defined as abnormal upward and/or posterior displacement of the odontoid leading to ventral compression of the cervicomedullary junction. This condition leads to lower cranial neuropathies, sensorimotor deficits, and myelopathy. These symptoms can persist even after posterior decompression, which is an indication for ventral decompression. Transoral approaches to the upper cervical spine carry significant morbidity, limiting their utility. The endonasal approach to the upper cervical spine presents an alternative for patients with amenable anatomy...

OBJECTIVE: The purpose of this article is to review the imaging findings of necrotizing fasciitis as seen on radiograph, ultrasound, CT, and MRI, and to recognize the early findings in this potentially fatal disease. CONCLUSION: Although classically a clinical diagnosis, imaging is a powerful adjunct to facilitate early diagnosis in equivocal cases. Compared to plain radiography, US, CT and MR provide higher sensitivity and specificity for the diagnosis of necrotizing fasciitis...

Central venous catheterization can be challenging in patients that had undergone repeated catheter placements. Ultrasound scan may overlook venous stenosis which is better visualized using venography. The use of venography should be considered to assess for venous stenosis or vascular anomalies in individuals with multiple catheterizations or in close proximity to cancer.

Sensitivity and selectivity of the solid phase microextraction (SPME) in analysis are mostly determined by the coating material of the fiber used. Graphene oxide (GO) has attracted great attention because of its large specific surface area, rich oxygen functional groups, good dispersibility in aqueous solution and high reactivity. However, the low thermal stability of the functional groups limits the wide application of GO in SPME coating design. Highly cross-linked polyoxyethylene (POE) is a substrate widely used for composite material construction, which could significantly improve the thermal stability, water resistance as well as biocompatibility of the functional materials...

BACKGROUND: The correct amount of external rotation of the femoral component during TKA is controversial because the resulting changes in biomechanical knee function associated with varying degrees of femoral component rotation are not well understood. We addressed this question using a computational model, which allowed us to isolate the biomechanical impact of geometric factors including bony shapes, location of ligament insertions, and implant size across three different knees after posterior-stabilized (PS) TKA...
