Amelioration of Toll-like Receptor-4 Signaling and Promotion of Mitochondrial Function by Mature Silkworm Extracts in Ex Vivo and in Vitro Macrophages.

Objectives: The unknown immune-enhancing effects of steamed mature silkworms ( L.), known as HongJam (HJ), were investigated.

Methods: Supercritical fluid extracts from the White Jade variety of HJ (WJ-SCEs) were applied to in vitro RAW264.

Antioxidant and cholesterol regulatory effect of flavonoid-rich silk sericin.

Cholesterol is a component of cell membranes and a precursor of hormones, and excess levels are associated with disease development; therefore, it must be maintained within the normal range. Silkworm cocoons are known to contain bioactive substances. Therefore, we compared the bioactivities of pigmented and white silkworm cocoons.

Modulatory Effects of the Kuwanon-Rich Fraction from Mulberry Root Bark on the Renin-Angiotensin System.

In this study, we investigated the anti-hypertensive properties of mulberry products by modulating the renin-angiotensin system (RAS). Comparative analysis showed that the ethyl acetate fractions, particularly from the Cheongil and Daeshim cultivars, contained the highest levels of polyphenols and flavonoids, with concentrations reaching 110 mg gallic acid equivalent (GE)/g and 471 mg catechin equivalent (CE)/g of extract, respectively. The ethyl acetate fraction showed superior angiotensin-converting enzyme (ACE) inhibitory activity, mainly because of the presence of the prenylated flavonoids kuwanon G and H.

Bombyx mori kynurenine 3-monooxygenase gene editing and insect molecular breeding using the clustered regularly interspaced short palindromic repeat/CRISPR associated protein 9 system.

Genome editing by clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR associated protein (Cas)9, a third-generation gene scissors, and molecular breeding at the genome level are attracting considerable attention as future breeding techniques. In the present study, genetic and phenotypic analyses were conducted to examine the molecular breeding of Bombyx mori through CRISPR/Cas9-mediated editing of the kynurenine 3-monooxygenase (KMO) gene. The synthesized guide RNAs (gRNAs) were analyzed using T7 endonuclease I after introduction into the BM-N silkworm cell line.

Asymptomatic cervical isthmic spondylolisthesis and associated occult spinal bifida: a case report.

We report a case of rare cervical isthmic spondylolisthesis of C6-7 combined occult spinal bifida at C6, and review the radiologic finding, different diagnosis and treatment. A 23-year old female presented nuchal, back pain after traffic accident. Radiologic finding showed the 6(th) cervical isthmic defect, spondylolisthesis and dysplasia.

Predictive risk factors for refracture after percutaneous vertebroplasty.

Objective: To identify risk factors for developing a vertebral refracture after percutaneous vertebroplasty.

Method: A retrospective analysis of 60 patients who had undergone percutaneous vertebroplasty between January 2008 and April 2010 was conducted. All patients were observed for a 1 year follow-up period, and fracture was defined when it was both clinically reported and radiographically confirmed.
