Bioactivity and structure-activity relationship of cinnamic acid derivatives and its heteroaromatic ring analogues as potential high-efficient acaricides against Psoroptes cuniculi.

A series of cinnamic acid derivatives and its heteroaromatic ring analogues were synthesized and evaluated for acaricidal activity in vitro against Psoroptes cuniculi, a mange mite. Among them, eight compounds showed the higher activity with median lethal concentrations (LC) of 0.36-1.

Cytotoxic activity, apoptosis induction and structure-activity relationship of 8-OR-2-aryl-3,4-dihydroisoquinolin-2-ium salts as promising anticancer agents.

As our continuing research, a series of 2-aryl-8-OR-3,4-dihydroisoquinolin-2-ium bromides were evaluated for cytotoxic activity on cancer cells and apoptosis induction in the present study. SAR was derived also. Among them, 23 compounds showed the higher cytotoxicity on MKN-45 cells with IC values of 1.

A Laser-Based Measuring System for Online Quality Control of Car Engine Block.

For online quality control of car engine production, pneumatic measurement instrument plays an unshakeable role in measuring diameters inside engine block because of its portability and high-accuracy. To the limitation of its measuring principle, however, the working space between the pneumatic device and measured surface is too small to require manual operation. This lowers the measuring efficiency and becomes an obstacle to perform automatic measurement.

A Fast and in-Situ Measuring Method Using Laser Triangulation Sensors for the Parameters of the Connecting Rod.

The connecting rod is a critical part inside the marine engine. The inspection of its important parameters is directly related to the assembly and quality of the marine engine. A coordinate measuring machine (CMM) is a conventional choice to measure the parameters of a connecting rod.

[Clinical utilization of veiled incision and sternocleidomastoid flap in parotidectomy of parotid benign tumors].

Purpose: To describe a modified technique of parotidectomy using face-lift approach and sternocleidomastoid flap.

Methods: Forty-six patients were divided into two groups; group 1 (23 cases) using veiled incision and sternocleidomastoid flap, group 2 (23 cases) using traditional incision (Blair's approach) without sternocleidomastoid flap. Postoperative complications included temporary facial paralysis and salivary fistula.

[A clinical retrospective study on modified parotidectomy in benign tumors of parotid gland].

Purpose: A clinical perspective study was designed for patients undergoing a modified parotidectomy to reduce complications of parotidectomy.

Methods: 110 patients were divided randomly into two groups; Group 1 (55 cases) was operated via routine surgical modality. Group 2(55 cases) was treated with preserving the fascia parotideomasseterica and great auricular nerve and partial parotidectomy.
