Fermentation Characteristics of Unripe Vinegar Production Using Acetic Acid Bacteria Isolated from Traditional Fermented Vinegars.

Here, we aimed to isolate an acetic acid bacterium that is suitable for the production of unripe vinegar from traditional fermented vinegars. We compared the halo sizes of isolates to select a strain with superior acetic acid production capabilities and selected P6 (P6) as the final strain. Using CY (CY) and KACC 17058 (KACC 17058) as controls, we analyzed the total phenolic compounds, total flavonoid content, antioxidant activities, and organic acids of the selected strain to verify its suitability for acetic acid fermentation.

Improvement of volatile aromatic compound levels and sensory quality of distilled derived from and co-fermentation.

Distilled , a Korean traditional alcoholic beverage, is produced by fermenting rice with a variety of microorganisms including molds, yeasts, and lactic acid-producing bacteria, followed by distillation. Our study sought to improve the quality of distilled through co-fermentation with and , known for producing volatile aromatic compounds during the early stages of fermentation. Analysis of volatile aromatic compounds in co-fermented distilled revealed a substantial increase in compounds with boiling points below 200 °C.

Does Erector Spinae Plane Block Have a Visceral Analgesic Effect?: A Randomized Controlled Trial.

The visceral analgesic efficacy of erector spinae plane block (ESPB) is still a matter of debate. This study attempted to investigate the visceral analgesic efficacy of ESPB in clinical setting. After randomized, we performed ultrasound-guided bilateral rectus sheath block (RSB), which was aimed to prevent postoperative somatic pain on all patients who underwent laparoscopic cholecystectomy (LC).

Preoperative versus Postoperative Rectus Sheath Block for Acute Postoperative Pain Relief after Laparoscopic Cholecystectomy: A Randomized Controlled Study.

Background: Pain after laparoscopic cholecystectomy (LC) is multifactorial and usually not effectively treated. Rectus sheath block (RSB) has been proven to reduce the pain from midline abdominal incision and laparoscopic surgery. We investigated the preemptive analgesic effect of RSB after LC.

Effect of Enhanced Recovery After Surgery program on pancreaticoduodenectomy: a randomized controlled trial.

Background: This study aims to investigate the noninferiority of Enhanced Recovery After Surgery (ERAS) for pancreaticoduodenectomy (PD).

Methods: In this single-center trial, we randomly assigned 276 adult patients who underwent open PD into ERAS and conventional groups with 138 patients in each, from 2015 through 2017. The primary endpoint was the incidence of overall morbidity until postoperative 3 months.

Population-based volume kinetics of Ringer's lactate solution in patients undergoing open gastrectomy.

In order to maintain stable blood pressure and heart rate during surgery, anesthesiologists need to administer the appropriate amount of fluid with appropriate fluid type to the patient, then quantifying how fluid is distributed and eliminated from the body is useful for establishing a fluid administration strategy. In this study we characterized the volume kinetics of Ringer's lactate solution in patients undergoing open gastrectomy. When propofol and remifentanil reached a pseudosteady state at the target concentration and blood pressure was stabilized following surgical stimulation, enrolled patients were administered 1000 mL of Ringer's lactate solution for 20 min, followed by continuous infusion at a rate of 6 mL/kg/h until the time of the last blood collection for volume kinetic analysis.

Efficacy of Pectoral Nerve Block Type II for Breast-Conserving Surgery and Sentinel Lymph Node Biopsy: A Prospective Randomized Controlled Study.

Objectives: The pectoral nerve block type II (PECS II block) is widely used for postoperative analgesia after breast surgery. This study evaluated the analgesic efficacy of PECS II block in patients undergoing breast-conserving surgery (BCS) and sentinel lymph node biopsy (SNB).

Methods: Patients were randomized to the control group (=40) and the PECS II group (=40).

Prognostic Impacts of Increases in Amino Transaminases Following Coronary Artery Bypass Grafting on Mortality.

Objective: To evaluate the prognostic impacts of postoperative increases in serum amino transaminases on 1-year mortality in patients who underwent coronary artery bypass graft.

Design: A retrospective analysis.

Setting: A tertiary care university hospital.

The predictive performance of infusion strategy nomogram based on a fluid kinetic model.

Background: In a previous study, fluid kinetic models were applied to describe the volume expansion of the fluid space by administration of crystalloid and colloid solutions. However, validation of the models were not performed, it is necessary to evaluate the predictive performance of these models in another population.

Methods: Ninety five consenting patients undergoing elective spinal surgery under general anesthesia were enrolled in this study.

Improved outcomes in liver transplantation in children with acute liver failure.

Objective: The aim of our study was to review the experiences of a living donor-dominant transplantation program for children with acute liver failure (ALF).

Methods: Data were derived from the retrospective chart review of 50 children with ALF in a major liver center in the Republic of Korea.

Results: A total of 50 children with ALF underwent 47 (94%) primary living donor liver transplantations and 3 (6%) cadaveric liver transplantations.

Antithrombotic effects of aspirin on 1- or 2-level lumbar spinal fusion surgery: a comparison between 2 groups discontinuing aspirin use before and after 7 days prior to surgery.

Study Design: Retrospective clinical analysis.

Objective: To study proper discontinuation date of aspirin in spinal fusion surgery.

Summary Of Background Data: It is thought that excess bleeding can be normalized if aspirin intake is discontinued approximately 7 days before surgery; however, the average life span of a platelet is generally regarded to be 7 to 10 days.

Long-term outcomes of pediatric living donor liver transplantation at a single institution.

There have only been a few studies on the long-term outcomes and prognostic factors after pediatric LDLT. We conducted a retrospective, single-center assessment of the outcomes as well as the demographic and clinical factors that influenced the poor outcomes in 113 children aged <16 (median age 21 months; 6 months-15.5 yr) who underwent 115 LDLTs, predominantly for biliary atresia (60.

Effects of anesthesia on fluid volume kinetics after infusion of colloid solution during blood donation.

Background: The fluid kinetics of intravenously infused colloid during inhalation anesthesia and hemorrhage have not been investigated. We therefore assessed fluid space changes during infusion of hydroxyethyl starch solution after hemorrhage in conscious and desflurane-anesthetized individuals.

Methods: Following the donation of 400 ml of blood, 500 ml of hydroxyethyl starch solution was infused over 20 minutes into wakeful and desflurane-anesthetized volunteers.

The effects of inspiratory to expiratory ratio on ventilation and oxygenation during high frequency partial liquid ventilation in a rabbit model of acute lung injury.

Background: We examined the effects of varying inspiratory to expiratory (I : E) ratio on gas exchange and hemodynamics during high frequency partial liquid ventilation (HFPLV), a combination of high frequency ventilation (HFV) and partial liquid ventilation (PLV), in a rabbit model of acute lung injury.

Methods: Twelve rabbits treated with repeated saline lavage were divided into two groups. In the HFPL group (n = 6), 6 ml/kg of perfluorodecaline was administered through the endotracheal tube.

Anterior segment congestion of a right liver lobe graft in living-donor liver transplantation and strategy to prevent congestion.

Background/purpose: A left lobe graft from a small donor will not usually fulfill the metabolic demands of a larger recipient in adult-to-adult living-donor liver transplantation (LDLT). One solution to this problem is to use a right lobe graft. However, the necessity of middle hepatic vein (MHV) outflow drainage from the anterior segment (AS) of a right lobe graft has not yet been clearly described in the literature.

Modified right liver graft from a living donor to prevent congestion.

Background: Right liver grafts without middle hepatic vein (MHV) drainage reconstruction resulted in severe congestion of the anterior segment (AS) in our early experience of adult-to-adult living donor liver transplantation (LDLT). However, a detailed strategy for preventing such congestion or the necessity of MHV reconstruction has not been discussed in LDLT using a right lobe graft.

Methods: From July 1997 to February 1998, two of five right lobe grafts without MHV drainage reconstruction were complicated with severe congestion of the AS.
