BaPb(CO)F: Enhancing Birefringence by a Multiunit Synergy Effect.

Carbonates are ideal birefringent materials because their π-conjugated [CO] groups are beneficial for large anisotropy. How to maximize the birefringence and maintain a wide transmittance simultaneously in carbonates is a great challenge. Adopting a multiple-functional group synergy strategy by combining alkaline-earth metal Ba with large ion radius, PbOF distorted hexagonal pyramid, and paralleled π-conjugated CO triangles together, we synthesized a new metal carbonate crystal, BaPb(CO)F.

Prospective cohort study on the clinical significance of interferon-γ, D-dimer, LDH, and CRP tests in children with severe mycoplasma pneumonia.

Background: Mycoplasma pneumoniae is a significant cause of respiratory infections in children, often leading to severe pneumonia. This study aimed to assess the clinical relevance of interferon-gamma (interferon-γ), D-dimer, lactate dehydrogenase (LDH), and C-reactive protein (CRP) as biomarkers in the severity of mycoplasma pneumonia in pediatric patients.

Methods: In this prospective study, 203 pediatric patients with mycoplasma pneumonia were classified into mild (123 patients) and severe (80 patients) groups.

The novel HLA-A*24:627 allele, identified by Sanger dideoxy nucleotide sequencing in a Chinese individual.

The HLA-A*24:627 allele differs from HLA-A*24:02:01:01 by one nucleotide substitution in codon 172 in exon 2.

The landscape of DNA methylation in asthma: a data mining and validation.

Human asthma is caused by interactions between a range of genetic and environmental factors. However, the specific pathogenesis of asthma remains controversial. This study explored the contribution of DNA methylation to asthma using computer learning methods.

Gradual replacement of all previously circulating respiratory syncytial virus A strain with the novel ON1 genotype in Lanzhou from 2010 to 2017.

ON1 is a novel genotype of human respiratory syncytial virus (HRSV) subtype A, in children with acute respiratory tract infections (ARTIs). However, there is not much data on the prevalence and clinical and molecular characterization in China.Our study is based on the children who had respiratory infections positive for RSV-A admitted by Gansu Provincial Maternity and Child-care Hospital in Lanzhou (northwestern China) during the last 7 epidemic seasons from 2010 to 2017.

[The detection and clinical feature of HcoV-nL63 in children with acute respiratory tract infection in Lanzhou city].

Objective: To investigate the prevalence and clinical characterization of HCoV-NL63 (NL63) in children with acute respiratory tract infections (ARTIs) in Lanzhou with other respiratory viruses. The prevalence of HBoV1 in ALRTI was obviously city,China.

Method: From November 2006 to October 2009,1169 nasopharyngeal aspirates (NPA) were collected from children under 14 years old with ARTIs.

Prevalence and patterns of bone loss in the first year after renal transplant in South East Asian patients.

Background: Limited data are available regarding patterns of bone loss in South East Asian renal transplant patients. We aimed to determine the prevalence of low bone density and factors contributing to bone loss in Singaporean patients in the first year after renal transplant.

Methods: Seventy-nine consecutive patients who underwent renal transplant were evaluated.

[The research of saffold virus in children with lower respiratory tract infection in Changsha].

Objective: To investigate prevalence of Saffold virus (SAFV) in Changsha area of hospitalized children with respiratory tract infection, and to discuss whether this virus is related to respiratory tract infection of children.

Methods: 643 nasopharyngeal aspirates samples were collected from hospitalized children with respiratory tract infection of the first affiliated hospital of Hunan nomal university during Nov. 2007 to Oct.

[Detection and clinical study on coronavirus HKU1 with acute lower respiratory tract infections of hospitalized children in Changsha].

Objective: In order to understand the epidemiological and virologic characteristics of coronavirus HKU1 infection in hospitalized children with acute respiratory tract infection (ARTI) in Changsha.

Methods: 1165 nasopharyngeal aspirates (NPA) specimens were collected from hospitalized children with ARTI between September 2007 and August 2008 in Changsha. Specimens were screened for pol gene of coronavirus HKU1 by polymerase chain reaction.

Human respiratory syncytial virus in children with acute respiratory tract infections in China.

There are limited data on the prevalence and clinical and molecular characterization of human respiratory syncytial virus (HRSV) in children with acute respiratory tract infections (ARTIs) in China. From December 2006 to March 2009, 894 nasopharyngeal aspirates (NPAs) were collected from children under 14 years of age with ARTIs. Samples were screened for HRSV and genotyped by reverse transcription-PCR (RT-PCR) and sequencing.

Prevalence and clinical and molecular characterization of human metapneumovirus in children with acute respiratory infection in China.

Background: Human metapneumovirus (HMPV), a newly discovered paramyxovirus, has been associated with acute respiratory tract infections (ARTIs). However, the prevalence and molecular characteristics of HMPV in China are still unclear.

Methods: A total of 661 nasopharyngeal aspirates (NPA) specimens were collected from 661 children with ARTIs between December 2006 and November 2008.

Human bocavirus infection in young children with acute respiratory tract infection in Lanzhou, China.

Human bocavirus (HBoV) is a recognized human parvovirus associated with acute respiratory tract infection. However, HBoV has yet to be established as a causative agent of respiratory disease. In this study, the epidemiological and virological characteristics of HBoV infection were studied in children with acute respiratory tract infection in China.

Prevalence and clinical characterization of a newly identified human rhinovirus C species in children with acute respiratory tract infections.

Human rhinovirus C (HRV-C) is a newly identified genotype of HRV found in patients with respiratory tract infections (RTIs); however, its epidemiological profile and clinical characteristics are not well understood. In this study, Chinese children with RTIs were screened for HRV-C and their epidemiological and clinical characteristics were analyzed. From December 2006 to November 2007, 406 nasopharyngeal aspirates from children younger than 14 years of age with RTIs were screened for HRV and other common respiratory viruses by PCR or reverse transcription-PCR.
