Clarification of the infection pattern of Xanthomonas citri subsp. citri on citrus fruit by artificial inoculation.

Background: Citrus canker is a significant bacterial disease caused by Xanthomonas citri subsp. citri (Xcc) that severely impedes the healthy development of the citrus industry. Especially when citrus fruit is infected by Xcc, it will reduce or even lost its commercial value.

The impact of adverse childhood experiences on depression in middle and late life: A national longitudinal study.

Background: Adverse childhood experiences (ACEs) are one of the causes of depression in middle-aged and older adults, but the combined effects of ACEs, cognitive function and ability to perform activities of daily living (ADL) on depression have not been fully explored.

Methods: This study was based on data from 4 waves (2013, 2014, 2015 and 2018) of data from the China Health and Retirement Longitudinal Study, including 10,995 middle-aged and older adults. ACEs were derived from the 2014 self-report life history module.

Investigation on the promotional role of GaO on the CuO-ZnO/HZSM-5 catalyst for CO hydrogenation.

Dimethyl ether (DME) can be directly synthesized from carbon dioxide and hydrogen by mixing methanol synthesis catalysts and methanol dehydration catalysts. The activity and selectivity of the catalyst can be greatly affected by the promoter; herein, we presented a series of CuO-ZnO-GaO/HZSM-5 hybrid catalysts, which were prepared by the coprecipitation method. The effect of the GaO content on the structure and performance of the Ga-promoted Cu-ZnO/HZSM-5 based catalysts was thoroughly investigated.

Clinical Characteristics of H1N1 Influenza A-Associated Mild Encephalopathy with Reversible Splenial Lesion: 4 Pediatric Cases.

Objective: Mild encephalopathy with reversible splenial lesion (MERS) is associated with a variety of infections and anti-epileptic drug withdrawal. Here we report the clinical characteristics of H1N1 influenza A-associated MERS based on our experience of four pediatric cases.

Methods: A detailed retrospective analysis of four patients with H1N1 influenza A-associated MERS was performed at Guangzhou Women and Children's Medical Center.

Citron C-05 inhibits both the penetration and colonization of subsp. to achieve resistance to citrus canker disease.

Citrus canker, caused by subsp. (), is a serious bacterial disease that affects citrus production worldwide. Citron C-05 () is the only germplasm in the genus that has been identified to exhibit strong resistance to .

A novel Enterovirus 96 circulating in China causes hand, foot, and mouth disease.

Enterovirus 96 (EV-96) is a recently described member of the species Enterovirus C and is associated with paralysis and myelitis. In this study, using metagenomic sequencing, we identified a new enterovirus 96 strain (EV-96-SZ/GD/CHN/2014) as the sole pathogen causing hand, foot, and mouth disease (HFMD). A genomic comparison showed that EV-96-SZ/GD/CHN/2014 is most similar to the EV-96-05517 strain (85% identity), which has also been detected in Guangdong Province.

[Analysis of clinical characteristics of the 12 cases of neonatal dengue fever in Guangzhou in 2014 and literatures review].

Objective: To explore the clinical manifestations and laboratory examination characteristics of neonatal dengue fever.

Method: A retrospective analysis of 12 cases of neonatal dengue fever treated in the Guangdong Women and Children's Hospital and Guangzhou Women and Children's Medical Center was conducted, and related literature was reviewed.

Result: Twelve cases of neonatal dengue fever included 9 males and 3 females; their age was 30 min after birth to 29 d, the age of onset was 30 min-24 d.

Alterations of signaling pathways in muscle tissues of patients with amyotrophic lateral sclerosis.

Introduction: Amyotrophic lateral sclerosis (ALS), a degenerative disorder of the central nervous system, manifests as progressive weakening of muscles. The diagnosis and prognosis of ALS are often unclear, so useful biomarkers are needed.

Methods: Total proteins were extracted from muscle samples from 36 ALS, 17 spinal muscular atrophy (SMA), and 36 normal individuals.

The perinatal infection of cytomegalovirus is an important etiology for biliary atresia in China.

Aims: The aims of this study were to detect the infection rates of DNA viruses in liver tissue of biliary atresia and to investigate the effect of perinatal infection of cytomegalovirus in biliary atresia.

Methods: A total of 85 liver biopsies (taken during Kasai portoenterostomy) were tested by fluorescence quantitative polymerase chain reaction for DNA viruses (herpes simplex virus [HSV], Epstein-Barr virus [EBV], varicella zoster virus [VZV], cytomegalovirus [HCMV], and adenovirus). Immunocytochemical detection of CMV-pp65 antigenemia assay was used to detect the presence of viral protein in liver samples.
