Characterization of Hsp70 gene family provides insight into its functions related to microsporidian proliferation.

Heat shock protein 70 (Hsp70), a highly conserved protein family, is widely distributed in organisms and plays fundamental roles in biotic and abiotic stress responses. However, reports on Hsp70 genes are scarce in microsporidia, a very large group of obligate intracellular parasites that can infect nearly all animals, including humans. In this study, we identified 37 Hsp70 proteins from eight microsporidian genomes and classified them into four subfamilies (A-D).

Morphology and Transcriptome Analysis of Nosema bombycis Sporoplasm and Insights into the Initial Infection of Microsporidia.

Microsporidia are obligate intracellular parasites that infect a wide variety of host organisms, including humans. The sporoplasm is the initial stage of microsporidian infection and proliferation, but its morphological and molecular characteristics are poorly understood. In this study, the sporoplasm of was successfully isolated and characterized after the induction of spore germination The sporoplasm was spherical, 3.

Evolutionary and functional studies on microsporidian ATP-binding cassettes: Insights into the adaptation of microsporidia to obligated intracellular parasitism.

ATP-binding cassette (ABC) transporters comprise the largest family of transmembrane proteins and are found in all domains of life. The ABCs are involved in a variety of biological processes and as exporters play important roles in multidrug resistance. However, the ABC transporters have not been addressed in microsporidia, which are a very large group of obligate intracellular parasites that can infect nearly all animals, including humans.

Pathological analysis of silkworm infected by two microsporidia Nosema bombycis CQ1 and Vairimorpha necatrix BM.

Microsporidia Nosema bombycis CQ1 can be vertically transmitted in silkworm Bombyx mori but Vairimorpha necatrix BM cannot. Therefore, the pathological differences in silkworm infected with these two microsporidia required clarification. Here, we compared the virulence of N.

Precise hepatectomy guided by minimally invasive surgery: a novel strategy for liver resection.

Liver resection has been established currently as an effective and standard treatment for patients suffering from both benign and malignant hepatobiliary diseases. Although substantial improvement in perioperative mortality rate and morbidity resulting from appropriate candidates selection, advanced surgical techniques and enhanced perioperative care, hepatectomy is still burdened by about 5% mortality rate and some lethal postoperative complications, especially postoperative liver insufficiency and failure. Various approaches have been advocated to minimize stress and insult on patients due to operative procedures.

microRNA expression alteration after arsenic trioxide treatment in HepG-2 cells.

Background And Aim: More and more microRNA (miRNA) are found to be involved in tumor genesis and progress. Arsenic trioxide has been an effective chemotherapeutic drug in cancer therapy for many years. In this study, we aimed to find the miRNA involved in the mechanisms of arsenic trioxide treatment in cancer therapy.

[The importance of nonrecurrent laryngeal nerve in thyroid surgery].

Objective: To investigate the anatomic variation of nonrecurrent laryngeal nerve (NRLN) and its surgical identification and prevention during thyroidectomy.

Methods: The database of 5 NRLN cases was analyzed to investigate the difference of operative maneuvers and procedures.

Results: All 5 NRLN were located in the right side.
