Protein-cage nanoparticles are promising multifunctional platforms for targeted delivery of imaging and therapeutic agents owing to their biocompatibility, biodegradability, and low toxicity. The major advantage of protein-cage nanoparticles is the ability to decorate their surfaces with multiple functionalities through genetic and chemical modification to achieve desired properties for therapeutic and/or diagnostic purposes. Specific peptides identified by phage display can be genetically fused

Robotic-assisted laparoscopic radical prostatectomy (RARP) needs a steep Trendelenburg position and a relatively high CO2 insufflation pressure, and patients undergoing RARP are usually elderly. These factors make intraoperative ventilatory care difficult and increase the risk of perioperative pulmonary complications. The aim was to determine the efficacy of recruitment manoeuvre (RM) on perioperative pulmonary complications in elderly patients undergoing RARP. A total of 60 elderly patients sch

Background In free flap reconstruction for head and neck cancer, achieving a haemodynamic target using excessive fluid infusion is associated with decreased flap survival rates and extended hospital stays. We hypothesized that goal‐directed haemodynamic therapy would improve flap survival rates and shorten hospitalization periods. Methods Patients scheduled for free flap reconstruction were randomly assigned to a goal‐directed haemodynamic therapy group ( n = 31) or a conventional haemodynamic t

The use of sevoflurane in maintaining anesthesia during INR was associated with faster recovery, less patient movement during the procedure, and a more stable hemodynamic response when compared to propofol.

BACKGROUND: Optic nerve sheath diameter (ONSD) is a well-known surrogate marker for intracranial pressure during robot-assisted laparoscopic radical prostatectomies (RALP). ONSD during RALP is known to increase due to elevated intracranial pressure as a result of the steep Trendelenburg position and carbon dioxide pneumoperitoneum. We aimed to compare the effects of total intravenous anesthesia (TIVA) and desflurane anesthesia (DES) on ONSD during RALP. METHODS: Patients scheduled for RALP were

The administration of ramosetron (0.3 mg) significantly attenuated the SA-induced decrease in BP compared with 4 or 8 mg of ondansetron and HR compared with 4 mg of ondansetron.

Scarless remote access endoscopic and robotic thyroidectomy has been recently performed as a safe and feasible method. However, little is known about the laryngo-pharyngeal complications after surgery and the effect of adjusting the endotracheal tube cuff pressure during surgery on laryngo-pharyngeal complications. Patients were randomized into two groups: the control group (n = 52) and adjusted group (n = 52). The initial cuff pressure was set to 25 mmHg and then monitored without adjustment (c

Superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis is the most commonly used treatment for Moyamoya disease. During the perioperative period, however, these patients are vulnerable to ischemic injury or hyperperfusion syndrome. This study investigated the ability of combined remote ischemic pre-conditioning (RIPC) and remote ischemic post-conditioning (RIPostC) to reduce the occurrence of major neurologic complications in Moyamoya patients undergoing STA-MCA anastomosis. Th

Abstract Regulatory T cells (T reg ) are CD4 + T cells with immune-suppressive function, which is defined by Foxp3 expression. However, the molecular determinants defining the suppressive population of T cells have yet to be discovered. Here we report that the cell surface protein Lrig1 is enriched in suppressive T cells and controls their suppressive behaviors. Within CD4 + T cells, T reg cells express the highest levels of Lrig1, and the expression level is further increasing with activation.

Takayasu's arteritis (TA) is a chronic inflammatory disease involving the aorta. Because TA sometimes involves cerebral arteries, anesthetic debates focus on cerebral monitoring. There is limited evidence as to which cerebral monitoring method is most adequate. Furthermore, there is insufficient evidence to determine which anesthetic technique is better for TA parturients. We experienced the case of a TA parturient who developed transient cerebral ischemia during cesarean section. The patient's

BIS values between 50 and 59 for interventional neuroradiology were associated with a more rapid recovery and favorable hemodynamic response, but also with more patient movement. We suggest that maintaining BIS values between 40 and 49 is preferable for the prevention of patient movement during anesthesia for interventional neuroradiology.

Catheter-related bladder discomfort (CRBD) is one of the most difficult symptoms during the postoperative period. Nefopam is a non-narcotic analgesic agent, which also has anticholinergic action. This study was performed to evaluate the effects of nefopam on CRBD in male patients undergoing robotic nephrectomy. A total of 109 male patients were randomly divided into two groups: the control group (n = 55) received 20 mL of normal saline, and the nefopam group (n = 54) received 20 mg of nefopam 1

ABSTRACT: Motor-evoked potential (MEP) monitoring is an essential monitoring for clinicians to improve outcomes. Although unacceptable movement during MEP is a rare complication but it can lead to terrible results. The aim of this study was to evaluate the risk factors associated with unacceptable movements in patients undergoing brain surgery with MEP monitoring.We performed a retrospective observational study of patients who underwent brain surgery with MEP monitoring under general anesthesia

최근 행복에 대한 관심이 증가하는 가운데 개인의 행복을 예측하는 다양한 심리적인 변인들에 대한연구가 많이 이루어졌다. 그러나 아직까지 국내에서는 거시적 수준에서의 환경적인 요인들을 고려한 행복 연구가 부족한 실정이다. 이에 본 연구는 개인의 행복 수준을 예측하는 거시적인 요인으로 지역을 살펴보았고, 대한민국에 거주하고 있는 사람들의 주관적 안녕감이 17개 권역에 따라 어떻게 다른 지를 조사하였다. 이를 위해 소셜미디어에서 수집한 데이터를 활용하여 총 1,039,426명의 2,261,667건수의 응답을 분석하였다. 본 연구는 대규모 데이터를 활용함으로써 제한된 표본을 가진 기존 연구의 한계를 극복하였으며 기존 연구에서 사용한 측정치를 보완한 종합적인 행복 측정치인 안녕지수를 활용하였다. 다층적인 구조를 가지고 있는 자료의 특성을 고려하여 저자들은 위계적 선형 모형(hierarchical linear modeling)을 이용하였으며, 분석 결과 응답자들의 행복은 17개 권역에 따라 유의
