BACKGROUND The facial profile is determined by the facial soft tissue thickness (FSTT) and dentoskeletal characteristics. The aim of this study was to compare male and female characteristics of FSTT in different orthodontic malocclusions using cephalometric radiography. MATERIAL AND METHODS One hundred and twenty lateral cephalometric radiography-derived cephalograms of adult male (n=47) and female (n=73) orthodontic patients, aged between 16-22 years were classified according to their dentoskeletal relationships as Class I (n=30), Class II Division 1 (n=30), Class II Division 2 (n=30), Class III (n=30)...

BACKGROUND Cancer immunotherapy is the use of the immune system to treat cancer. After years of research, there have been a significant number of publications in this field. We analyzed the literature and performed a hotspot analysis to identify important areas of future scientific research. MATERIAL AND METHODS Articles (2945) related to cancer immunotherapy published in the past 3 years were selected as the research sample. BICOMB software was then used to retrieve the high-frequency words and construct a text/co-word matrix...

BACKGROUND Osteoarthritis is a common degenerative disease of joints, and animal models have important significance in the investigation of this disease. The aim of this study was to develop a better method for developing osteoarthritis models in primates by comparing the modified Hulth score combined with joint scratches modeling method with others. MATERIAL AND METHODS We randomly divided 15 young male Macaca fascicularis and 3 old male Macaca fascicularis into 6 groups (n=3). Knee osteoarthritis (KOA) models were developed with different methods: modified Hulth combined with joint scratches (Group A), modified Hulth (Group B), Hulth (Group C), spontaneous models (Group D); sham-operated (Group E), and blank control (Group F)...

BACKGROUND Rac1 signaling plays a crucial role in controlling macrophage functions in CD. Peptidoglycan triggers several intracellular signaling pathways, including activation of Rac1, to regulate the function of macrophage. Suppressed Rac1 signaling in non-inflamed colonic mucosa of Crohn's disease patients has been shown to correlate with increased innate immunity. MATERIAL AND METHODS We examined the effect of peptidoglycan on Rac1 signaling in macrophages and mucosal tissue samples collected from 10 patients with active Crohn's disease and further investigated the effects of peptidoglycan on apoptosis and phagocytic activities of macrophages in vitro...

BACKGROUND Obstructive jaundice is a serious, life-threatening condition that can lead to death as a result of sepsis and multiorgan failure due to bacterial translocation. Treatment should be started as soon as possible after diagnosis. MATERIAL AND METHODS Forty 24-week-old male Sprague Dawley rats, with an average weight of 250 g to 300 g, were included in this study. The rats were randomly placed into five groups, each group consisted of eight rats. The sham group underwent only common bile duct (CBD) dissection and no ligation was performed...

Yu Hou, Xin Lu, Yueju Zhang
BACKGROUND The aim of this study was to assess the effects of interleukin-1 (IL-1) receptor associated kinase (IRAK) inhibitors on intestinal injury induced by necrotizing enterocolitis (NEC) in neonatal rats and its regulation on the intestinal Toll-like receptor (TLR) inflammatory signaling pathway. MATERIAL AND METHODS The neonatal rat models of NEC were established though hypoxia-cold stimulation. All rats were divided into 3 groups: an NEC model group (NEC group), an IRAK inhibitor group (IRAKI group), and a normal control group (NC group)...

BACKGROUND Increasing the success rate of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) is a duty of clinicians that has made many seek a variety of protocols. This study was undertaken to use a liquid chromatography-mass spectrometry (LC-MS) to define the alterations of follicular fluid (FF) lipid metabolites in patients undergoing progestin-primed ovarian stimulation (PPOS) compared with short-term protocol, revealing potential correlations between the differentially expressed lipids and ameliorative clinical outcomes...

BACKGROUND Mandibular third molar extraction surgery has a postoperative complication of hypoesthesia of the lower lip and/or chin. The objective of the study was to determine if preoperative radiographic examination by panoramic radiography and computed tomography (CT) scan can predict postoperative complications of mandibular third molar extraction surgery. MATERIAL AND METHODS In total, 479 patients who had mandibular third molar extraction surgery were included in this cross-sectional study. Patients had panoramic radiographies and CT scans to determine the relationship of the tooth, the canal, and the buccolingual position...

Munetaka Hirose, Yoshiko Kobayashi, Shiro Nakamoto, Ryusuke Ueki, Nobutaka Kariya, Tsuneo Tatara
BACKGROUND Routine hemodynamic monitoring parameters under general anesthesia, such as heart rate (HR), systolic blood pressure (SBP), and perfusion index (PI), do not solely reflect intraoperative nociceptive levels. We developed a hemodynamic model combining these 3 parameters for nociceptive responses during general anesthesia, and evaluated nociceptive responses to surgical skin incision. MATERIAL AND METHODS We first retrospectively performed discriminant analysis using 3 values - HR, SBP, and PI - to assess response to skin incision during tympanoplasty, laparoscopic cholecystectomy, and open gastrectomy to determine if combined use of these parameters differentiates nociceptive levels among these 3 surgeries...

BACKGROUND The co-existence of coronary heart disease (CHD) and lung cancer is increasing in an increasingly aging population. The aim of this study was to evaluate patient outcome from combined off-pump coronary artery bypass graft (CABG) surgery and lung resection in patients more than 50 years-of-age. MATERIAL AND METHODS A retrospective clinical study of 23 patients with a mean age of 70.2±8.4 years (range, 51-86 years) included 18 men and five women with CHD and lung cancer who underwent a single operation with combined off-pump CABG surgery and lung resection, for non-small cell lung cancer (NSCLC) (n=22) and small cell lung cancer (n=1)...

BACKGROUND Breast cancer is one of the most common female cancers in the world. As a key integrator of cell signaling pathways, IQGAP1 contributes to the development and progression of several cancers. However, the exact effects and molecular mechanisms of IQGAP1 in breast cancer progression remain poorly understood. MATERIAL AND METHODS In the present study, IQGAP1 expression was measured in 96 paired breast cancer samples and the corresponding adjacent non-cancerous tissues by immunohistochemistry and quantitative polymerase chain reaction...

BACKGROUND Gastrointestinal stromal tumor (GISTs) rarely occurs outside the GI tract as extragastrointestinal stromal tumor (EGIST). The aim of this study was to review the clinical presentation, diagnosis, and outcome of EGIST at a single center. MATERIAL AND METHODS The study was a retrospective study performed at Istanbul University Hospital in a 16-year period and included patients with a histopathological diagnosis of EGIST confirmed to arise outside the GI tract. The patients' available medical records included patient demographics, imaging and surgical data, and diagnostic histopathology reports...

BACKGROUND Anaerobic glycolysis is an important physiological process of all cancer cells. Butein has been reported to demonstrate substantial antitumor activities in various cancers. However, the effect of butein on tumor glycolysis remains unclear. In this study, the effect of butein on tumor glycolysis and the underlying mechanism were investigated in hepatocellular carcinoma (HCC).

BACKGROUND A low frequency pulsed electromagnetic field (PEMF) has been confirmed to play an important role in promoting the osteogenic differentiation of human bone marrow stem cells (BMSCs). Adipose-derived stem cells (ASCs) possess some attractive characteristics for clinical application compared to BMSCs, such as abundant stem cells from lipoaspirates, faster growth, less discomfort and morbidity during surgery. ASCs can become adipocytes, osteoblasts, chondrocytes, myocytes, neurocytes, and other cell types...
