Microbial response to the chronic toxicity effect of graphene and graphene oxide nanomaterials within aerobic granular sludge systems.

Nanomaterials present in wastewater can pose a significant threat to aerobic granular sludge (AGS) systems. Herein, we found that compared to graphene nanomaterials (G-NMs), the long-term presence (95 days) of graphene oxide nanomaterials (GO-NMs) resulted in an increased proliferation of filamentous bacteria, poorer sedimentation performance (SVI of 74.1 mL/g) and smaller average particle size (1224.

Species richness and endemism patterns of Sternorrhyncha (Insecta, Hemiptera) in China.

One of the main goals in biogeography and ecology is the study of patterns of species diversity and the driving factors in these patterns. However, such studies have not focused on Sternorrhyncha in China, although this region hosts massive species distribution data. Here, based on the 15,450 distribution records of Sternorrhyncha species in China, we analyzed patterns in species richness and endemism at 1° × 1° grid size and determined the effects of environmental variables on these patterns using correlations analysis and the model averaging approach.

Revealing the influencing mechanisms of polystyrene microplastics (MPs) on the performance and stability of the algal-bacterial granular sludge.

Algal-bacterial granular sludge (ABGS) is an energy-saving and environment-friendly wastewater treatment technology; however, the effects of microplastics (MPs) on the performance and stability of the ABGS system remain unknown. Herein, the influencing mechanisms of polystyrene MPs (50 μm) on the ABGS were systematically investigated. The ABGS exhibited a high removal efficiency of MPs (over 96%) at 1 mg/L and 20 mg/L.

Role of rotating speed on the stability of a self-sustaining algal-bacterial photo-granules process.

The effects of rotating speed (120, 130, 140 and 150 rpm) of a photo-reactor on the self-sustaining algal-bacterial photo-granules sludge (ABPG) was investigated in this study. The ABPG process maintained good granular stability at 140 rpm with an integrity coefficient of 3.0% and excellent nutrient removal.

Some species of the subgenus Tachycines (Gymnaeta) inhabit caves. In this study, a new species of, Gymnaeta namely Tachycines (Gymnaeta) lalinus sp. nov.

The epidemiology of paediatric Mycoplasma pneumoniae pneumonia in North China: 2006 to 2016.

Paediatric Mycoplasma pneumoniae pneumonia (MPP) is a major cause of community-acquired pneumonia in China. Data on epidemiology of paediatric MPP from China are little known. This study retrospectively collected data from June 2006 to June 2016 in Beijing Children's Hospital, Capital Medical University of North China and aims to explore the epidemiological features of paediatric MPP and severe MPP (SMPP) in North China during the past 10 years.

Clinical and genetic characteristics of Chinese pediatric patients with chronic granulomatous disease.

Background: Chronic granulomatous disease (CGD) is a rare disease in China, and very little large-scale studies have been conducted to date. We aimed to investigate the clinical and genetic features of CGD in Chinese pediatric patients.

Methods: Pediatric patients with CGD from Beijing Children's Hospital, Capital Medical University, China, were enrolled from January 2006 to December 2016.

Body Mass Index (BMI) is Associated with the Therapeutic Response to Oral Rehydration Solution in Children with Postural Tachycardia Syndrome.

We aimed to explore whether the body mass index (BMI) was associated with the therapeutic response to oral rehydration solution (ORS) in children with postural tachycardia syndrome (POTS). Fifty-four children diagnosed as having POTS were included in this study. Fifty-six healthy children served as the controls.

[Predictive value of baseline plasma midregional fragment of pro-adrenomedullin level on long-term outcome of postural tachycardia syndrome children treated with midodrine hydrochloride].

Objective: To explore the predictive value of baseline plasma midregional fragment of pro-adrenomedullin level (MR-proADM) on long-term survival of postural tachycardia syndrome (POTS) children treated with midodrine hydrochloride.

Methods: Fifty-three children (male 26, mean age (14.5 ± 4.

Erythrocytic hydrogen sulfide production is increased in children with vasovagal syncope.

Objectives: To explore the differences in erythrocyte hydrogen sulfide (H2S) production in children with vasovagal syncope (VVS).

Study Design: A total of 54 children including 27 with VVS, aged 6-16 years (mean age 11.3 ± 3.

[Clinical characteristics of primary ciliary dyskinesia in children].

Objective: Although primary ciliary dyskinesia (PCD) is a group of inherited diseases, accurate diagnosis and appropriate clinical care to prevent and treat the complications could maintain patients' quality of life and normal life span. The diagnosis of PCD may often be delayed because it is frequently misdiagnosed as bronchitis, sinusitis and otitis. This study aimed to analyze and summarize the clinical features of PCD and explore diagnostic and differential diagnostic procedures in children.

[Clinical analysis of pediatric SARS cases in Beijing].

Objective: To study clinical characteristics of pediatric SARS cases in Beijing.

Methods: Eighteen pediatric cases with SARS diagnosed on admission were analyzed. The cases were admitted to Beijing Children's Hospital and Ditan Hospital (pediatric ward) from April 8 to May 12.
