Preoperative optimization strategy management model applied in gallbladder surgery.

Purpose: To investigate the impact of implementing a pre-hospitalization optimization strategy on the length of stay and hospital costs for patients undergoing gallbladder surgery at a tertiary hospital, this study aims to analyze patient characteristics relevant to pre-hospitalization gallbladder surgery, focusing on age and underlying medical conditions.

Method: The data from patients who underwent the pre-hospitalization optimization strategy were analyzed and compared with that of patients receiving standard hospitalization to determine whether there were statistically significant differences in duration of stay and associated costs.

Results: Under the optimal management strategy for pre-hospitalization, we analyzed the hospitalization of patients with and without underlying diseases, specifically comparing those aged over 65 years to those under 65 years, against a cohort of general hospitalized patients.

Electrochemical impedance spectrum frequency optimization of bitter taste cell-based sensors.

Electrochemical impedance spectrum frequency optimization to bitter taste receptor cell-based sensors is discussed in this paper. The bitter taste receptor cells (the enteroendocrine STC-1 cells and the ICR mouse isolated taste bud cells) are cultured on carbon screen printed electrodes and used as sensing elements. The HEK-293 cells and dead isolated ICR mouse taste bud cells, without bitter taste receptor expression, are used in negative control experiments.

Sweet and bitter tastants specific detection by the taste cell-based sensor.

Sweet and bitter tastants specific detection by cell-based sensor is investigated in this paper. Human enteroendocrine NCI-H716 cells, expressing G protein-coupled receptors and sweet receptors (type 1, member 2/type 1, member 3), and human enteroendocrine STC-1 cells, expressing G protein-coupled receptors and bitter receptors (type 2 members) are used as sensing devices. The HEK-293 cells, without taste receptor expression, are used as negative control.

[Effects of ionic-dissolution of sol-gel bioactive glasses on human dental pulp cells].

Objective: To evaluate the effects of ionic-dissolution of sol-gel bioactive glasses (BG) on proliferation and alkaline phosphatase (ALP) activity of human dental pulp cells (HDPCs) .

Methods: The primary HDPCs were isolated from intact premolar and third molars and were cultured in DMEM. Then the 4 th generation of HDPCs were cultured in DMEM, which contained 1 g/L of one of 58S, Nano-58S, and 45S5 ionic-dissolution products.
