Abstract

To dynamically observe the effects of electroacupuncture (EA) on repair of gastric mucosal lesion in rats with gastric ulcer, and to explore the time-effect relationship and molecular mechanism of EA for gastric ulcer. A total of 72 SD rats were randomly assigned to a normal group, a model group, a acupoint group and a sham acupoint group, and each group were further divided into a 1-day subgroup, a 4-day subgroup and a 7-day subgroup, 6 rats in each subgroup. The rat model of gastric ulcer was established by using intragastric administration of ethyl alcohol. The rats in the acupoint group were treated with EA at"Zusanli"(ST 36) and"Liangmen"(ST 21); the rats in the sham acupoint group were treated with EA at points 5 mm next to"Zusanli"(ST 36) and"Liangmen"(ST 21); the EA was given 30 min per treatment, once a day. The rats in the normal group and model group were treated with immobilization for 30 min per day, and no EA was given. PR-PCR method was applied to test the expression of proliferating cell nuclear antigen (PCNA) and substance P (SP); Western blot method was applied to test the expression of neurotensin (NT). After 1-day treatment, the ulcer index in the model group was higher than that in the normal group (P<0.01)...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.
