Abstract

To understand the endemic situation and impact factors of paragonimiasis in Sichuan Province, so as to provide the evidence for its control work. Four administrative villages from Xuanhan County, Kaijiang County, Pengzhou City and Yucheng District of Ya'an City were selected as regular surveillance sites. In the surveillance sites, ELISA was applied to test the infection situation of residents, questionnaire surveys were performed simultaneously; and water crabs were collected to detect the metacercariae of Paragonimus. From 2011 to 2013, totally 3 666 residents were tested by serum test and 104 of them were positive with a positive rate of 2.8%. Totally 3 671 residents underwent the questionnaire survey and 24.8% of them had heard about paragonimiasis, 36.3% had eaten undercooked water crabs, 56.4% had played with water crabs, and 84.6% had drunk stream water. Totally 2 463 water crabs were dissected, and metacercariae of Paragonimus were found in 620 of them with the infection rate of 25.2% and infectiosity of 4.53 per crab, respectively. The endemic situation of paragonimiasis in natural environments is serious in Sichuan Province. The residents in endemic area practice unhealthy diet behavior, and there is an urgent risk of...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
