Managing recovered COVID-19 patients with recurrent-positive SARS-CoV-2 RNA test results is challenging. We performed a population-based observational study to characterize the viral level and serum antibody responses in evaluate their transmission risk. Of 479 patients, 93 (19%) were identified, characterized by younger age, median discharge-to-recurrent-positive length of 8 days. After readmission, exhibited mild (28%) or absent (72%) symptoms, no disease progression. The ranged from 1.8...
Intracellular deposition of α-synuclein and tau are hallmarks synucleinopathies tauopathies, respectively. Recently, several dye-based imaging probes with selectivity for aggregates have been developed, but suitable biomarkers still unavailable. Detection both these early in the disease process may allow prophylactic therapies before functional impairments manifested, highlighting importance developing specific lesions. In contrast to β sheet dyes, single-domain antibodies, found camelids a...
Acute infectious gastroenteritis is one of the most common diseases among all ages, particularly in developing countries. The pathogen spectrum may differ different regions and seasons. To investigate etiology acute diarrhea Shenzhen, a prospective study was conducted from August 2014 to September 2015. Stools 412 patients with (286 whom were adults) including general epidemiological information collected. 19 pathogens detected by conventional culture method or multiplex PCR assay, which...
Stem cells utilized for ischemic stroke treatment often display unstable homing capabilities and diminished activity in vivo, limiting their neuroprotective efficacy. Furthermore, the optimal delivery route stem remains undetermined. While cytokines secreted by show promise modulating post-stroke inflammation, direct application of these supernatants underlying mechanisms are still unclear. Secretory (hMSC-L) cell lysate products (hMSC-M) from primary human umbilical cord mesenchymal...

Abstract Background SARS-CoV-2 is a newly emerged coronavirus, causing the coronavirus disease 2019 (COVID-19) outbreak in December, 2019. As drugs and vaccines of COVID-19 remain development, accurate virus detection plays crucial role current public health crisis. Quantitative real-time reverse transcriptase-polymerase chain reaction (RT-qPCR) kits have been reliably used for RNA since beginning outbreak, whereas isothermal nucleic acid amplification-based point-of-care automated also...
Cerebral ischemia-reperfusion injury induces a secondary immune inflammatory reaction that exacerbates brain and clinical prognosis. Dendritic cells (DCs) microglia are both important regulators of neuroinflammation. Studies have confirmed large number express the DC surface marker CD11c in ischemic area, some these also microglial markers. However, specific mechanism transformation between DCs their roles process cerebral still not clear. In this study, we established mouse model flow...

To understand the prevalence, genetic characteristics and drug resistance features of Salmonella Kentucky ST314 in Shenzhen.
Background: Enteric fever remains a serious public health problem. S. Typhi and Paratyphi A are the two predominant causes of enteric fever. The spread outbreaks caused by antimicrobial resistant pathogens pose major threat to health. Understanding transmission dynamics these is crucial for design implementation effective control strategies.Methods: In this study, we sequenced 135 isolates 271 in Shenzhen from 2001 2017. Phylogenomic analysis Bayesian were employed investigate combining...

Rapid and accurate identification of Salmonella enterica serotypes Typhi Paratyphi (A, B C), the causal agents enteric fever, is critical for timely treatment, case management evaluation health policies in low middle-income countries where disease still remains a serious public problem. The present study describes development multiplex assay (EFMAtyping) simultaneous pathogens causing typhoid paratyphoid fever single reaction by MeltArray approach, which could be finished within 2.5 h. Seven...
Abstract Background Synucleinopathies lack cures. Antibody therapies targeting α‐synuclein aim to inhibit aggregation and enhance degradation, but have limited brain entry because of size (150kDa). Smaller single‐domain antibodies (sdAbs, 15kDa) substantially improved uptake. Previously, we developed sdAb‐based probes (2D10 2D8) enabling specific imaging in mice post i.v. injection, correlating with lesion burden, indicating therapeutic diagnostic potential (Jiang Y et al Sci Adv 2023)....
Summary Background Managing discharged COVID-19 (DC) patients with recurrent positive (RP) SARS-CoV-2 RNA test results is challenging. We aimed to comprehensively characterize the viral level and serum antibody responses in RP-DC evaluate their transmission risk. Methods A population-based observational cohort study was performed on 479 DC from February 1 May 5, 2020 Shenzhen, China. conducted RT-qPCR, assays, neutralisation virus isolation, whole genome sequencing (WGS), epidemiological...
Clostridium botulinum produces neurotoxins (BoNTs), which cause people who ingest them to become seriously ill and sometimes die. In recent years, sporadic food poisoning cases associated with C. have occurred across the world. 2016, two men were admitted our hospital in Shenzhen, China, foodborne botulism. this study, we report on these typical botulinum-related incidents steps taken identify characterize causative pathogen. We characterized bacterial pathogen isolated from first patient...
Abstract Background Synucleinopathies and tauopathies are characterized by progressive deposition of α‐synuclein (α‐syn) tau proteins, respectively. These diseases have been linked to proteins mutations or excess α‐syn gene, indicating prominent roles these in their etiology pathogenesis. Consequently, being able non‐invasively image aggregates would allow early accurate diagnosis facilitate clinical trials on drugs targeting lesions eventually for prophylactic therapies. Recently, several...
Abstract SARS-CoV-2 is a newly emerged coronavirus that was isolated from human infections in recent months. Since drugs and vaccines of Covid-19 are still being developed, accurate pathogen detection plays crucial role the current public health crisis. Quantitative real-time reverse transcriptase-polymerase chain reaction (RT-PCR) assay has been reliably used for confirmation since beginning outbreak, whereas isothermal nucleic acid amplification based point care automated assays also...
Abstract Background: Recently many literature were reported on the re-detectable positive phenomenon of COVID-19 patients during recovery, but there few studies lymphocyte subsets and T-lymphocyte activation indicators between RP (re-detectable positive) NRP (non-re-detectable patients.
