Diagnosis of Extraosseous Lesions Overlapping the Bones on Bone Scintigraphy.

Extraosseous MDP uptake was not uncommon on the bone scintigraphy. When the extraosseous activity is overlapping the bones, it might cause difficulty in interpreting the result when only static images were acquired. Here we report 2 cases that abnormal MDP activity overlapping the bones on planar images, which were confirmed as soft tissue lesions by SPECT/CT or CT imaging.

Knockdown of GFAT disrupts chitin synthesis in Hyphantria cunea larvae.

Glutamine-fructose-6-phosphate transaminase (GFAT) has been reported to regulate the hexosamine biosynthetic pathway as the first rate-limiting enzyme. As a key enzyme that catalyzes the substrate of glycosylation modification, which has a wide-ranging effect on cellular functions. However, there are few studies on the relationship between GFAT and chitin metabolism in insects.

[Construction of multi-dimensional teaching reform system of Biochemistry based on outcome-based education].

Biochemistry is an important fundamental course of biology related majors, and has the characteristics of speedy development, massive information, sound theoretical basis and feasible applicability. It is difficult for students to learn well in the process of teaching. In addition, the experimental course lacks integrity, comprehensiveness and design experiments.

Avermectin stress varied structure and function of gut microbial community in Lymantria dispar asiatica (Lepidoptera: Lymantriidae) larvae.

Lymantria dispar asiatica is a globally distributed herbivorous pest. Avermectin is a highly effective, broad-spectrum insecticide. In this study, fourth instar L.

Sodium pheophorbide a has photoactivated fungicidal activity against Pestalotiopsis neglecta.

Sodium pheophorbide a (SPA) is a natural photosensitizer. To explore its antifungal activity and mechanism, we studied its inhibitory effects on spore germination and mycelial growth of Pestalotiopsis neglecta. We used sorbitol, 2-thiobarbituric acid (TBA) and electron microscopy to determine its effects on cell wall integrity, cell membrane lipid peroxidation and mycelial morphology.

Cu/ZnSOD always responded stronger and rapider than MnSOD in Lymantria dispar larvae under the avermectin stress.

Metalloenzyme SODs play important roles in insects dealing with environmental stress. Here, we cloned the Cu/ZnSOD (LdCZS) and MnSOD (LdMS) mRNA of Lymantria dispar by rapid amplification of cDNA ends (RACE). Afterwards their expression patterns were detected by quantitative real-time polymerase chain reaction (qPCR) after bioinformatic analysis.
