Background: SurgiGuard is an absorbent hemostatic agent based on oxidized regenerated cellulose. The efficacy, effects and safety of SurgiGuard are equivalent to existing hemostatic agents in animal experiments. This study was designed to confirm that the use of SurgiGuard alone is effective, safe and feasible compared to combination with other hemostatic methods.

This paper is an overview of various features of regional anesthesia (RA) and aims to introduce spine surgeons unfamiliar with RA. RA is commonly used for procedures that involve the lower extremities, perineum, pelvic girdle, or lower abdomen. However, general anesthesia (GA) is preferred and most commonly used for lumbar spine surgery.

A tenosynovial giant cell tumor is a benign proliferative disease, mostly arising from the synovial membrane of tendon sheaths, bursae, and joints. Axial skeleton involvement is very rare, but it is often found in the cervical spine. Spinal tenosynovial giant cell tumors often arise at the facet joints; a completely extra-articular spinal tenosynovial giant cell tumor is rare.

Although participating in regular physical activity has many benefits, female Korean college students tend to have much lower participation rates than their male counterparts. An effective means of increasing physical activity among female college students is sport participation. The purpose of this study is to incorporate three types of psychological needs from self-determination theory as precursor background variables into the theory of planned behavior to predict sport participation among female Korean college students.

We investigated the anti-angiogenic and pro-apoptotic effects of robustaflavone (RF), a naturally occurring biflavonoid, on human umbilical vein endothelial cells (HUVECs). RF inhibited HUVEC proliferation and showed cytotoxicity that inhibited HUVEC viability. RF-induced apoptosis was characterized by flow cytometry and caspase 3 analysis.

Tumor angiogenesis and lymphangiogenesis are important processes in tumor progression and metastasis. The inhibitory effects of 3-O-acetyloleanolic acid (3AOA), a pentacyclic triterpenoid compound isolated from Vigna sinensis K., on tumor-induced angiogenesis and lymphangiogenesis in vitro and in vivo were studied.

Glutamate is an important neurotransmitter in the central nervous system; however, at high concentrations, it causes excitotoxicity and many neurological disorders. Excitotoxicity induces cell death by apoptosis. Thus, factors that can inhibit the apoptotic pathways are a target of drug development for the treatment and prevention of neurodegenerative diseases.

In this study, we expressed laccase from on the surface of spores for efficient decolorization of synthetic dyes. The , , and genes were used as anchoring motifs for efficient spore surface display of cotA laccase. Moreover, a His tag was inserted at the C-terminal end of for the immunological detection of the expressed fusion protein.

This study aimed to evaluate the safety and completeness of using intraoperative indocyanine green videoangiography (ICGV) combined with intraoperative angiography (IOA) for aneurysm clipping in a hybrid operating room (hOR). All patients who underwent microsurgical clipping in the hOR were identified from prospectively maintained neurosurgical databases. Medical charts and operative videos with ICGV and IOA were reviewed to determine the adequacy of clipping, and clinical and angiographic outcomes were retrospectively analyzed.

Rationale: Diffuse large B-cell lymphoma (DLBCL) is the most frequent human immunodeficiency virus (HIV)-related Non-Hodgkin's Lymphoma of the stomach. Although gastrointestinal (GI) bleeding due to primary gastric lymphoma has been previously reported in the literature, there have been no reports of stomach wall involvement of intra-abdominal lymphoma presenting as GI bleeding.

Patient Concerns: We present a rare case of direct invasion of DLBCL to the stomach wall that presented as upper GI bleeding in a patient with HIV.

Technical advances with devices such as catheters, balloons, and stents have widened the indications for endovascular coiling for unfavorable aneurysms. The authors report two cases of coil embolization for a wide-neck bifurcated aneurysm with anterograde horizontal stenting via microcatheter looping. Two women, aged 56 and 38 years, respectively, had an undertall- and overwide-neck aneurysm with bifurcated branches at the basilar bifurcation and middle cerebral bifurcation, respectively.

Article Synopsis
  • The study compares two immunotherapeutic agents: GA733-2-Fc and GA733-2-Fc-KDEL, which are designed to target human colorectal cancer.
  • Researchers produced these agents from Nicotiana benthamiana plants and analyzed their effects on immune responses and tumor regression in mice.
  • Results showed that GA733-2-Fc-KDEL was more effective in reducing tumor growth and eliciting stronger immune responses than GA733-2-Fc, demonstrating its potential as a better treatment option for colorectal cancer.

Background: Sentinel lymph node metastasis is a common and early event in the metastatic process of head and neck squamous cell carcinoma (HNSCC) and is the most powerful prognostic factor for survival of HNSCC patients. 3-O-acetyloleanolic acid (3AOA), a pentacyclic triterpenoid compound isolated from seeds of Vigna sinensis K., has been reported to have potent anti-angiogenesis and anti-tumor activities.

Purpose: A complicated course of the femoral route for neurointervention can prevent approaching the target. Thus, we determined whether transcervical access in the hybrid angiosuite is applicable and beneficial in real practice.

Methods: From January 2014 to March 2017, this approach was used in 17 of 453 (3.

The purpose of this review is the current understanding of proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) following adult spinal deformity (ASD) surgery. We carried out a systematic search of PubMed for literatures published up to September 2017 with "proximal junctional kyphosis," "proximal junctional failure," and "adult spinal deformity" as search terms. A total of 98 literatures were searched.

Objective: To evaluate the radiographic and clinical outcomes of percutaneous vertebroplasty (PVP) in patients with Kümmell's disease.

Methods: A retrospective review was conducted for 19 vertebrae in 18 patients, between January 2012 and June 2016. A visual analogue scale (VAS) score was used to determine each patient's subjective level of pain (0=no pain to 10=severe pain) preoperative, immediately postoperative and at the last follow-up (at least 12 months after PVP).

The neurogenic tumor of frequent occurrence in the presacral area is a schwannoma. Giant presacral schwannoma has a risk for anterior surgical approach because of its massive size and proximity to abundant vascularity of presacral region. We report a single stage posterior approach for total resection of a giant presacral schwannoma.

Background: Laminoplasty is a surgical procedure frequently performed for cervical myelopathy. We investigated correlations between changes in the anteroposterior diameter (APD) of the spinal canal, spinal canal area (SCA), and laminar angle (LA) and clinical outcomes of laminoplasty.

Methods: Of the 204 cervical myelopathy patients who underwent laminoplasty from July 2010 to May 2015, 49 patients who were evaluated with pre- and postoperative computed tomography of the cervical vertebrae were included.

We describe the inhibitory effects of recombinant canstatin on tumor growth and lymphangiogenesis induced by an oral squamous cell carcinoma (SCC) using an orthotropic oral SCC animal model. Recombinant canstatin treatment decreased final tumor volumes and weights, as well as densities of blood and lymphatic vessels. Lung metastasis of oral SCC was significantly reduced in recombinant canstatin-treated animals.

A rigid spino-pelvic fixation to anchor long constructs is crucial to maintain the stability of long fusion in spinal deformity surgery. Besides obtaining immediate stability and proper biomechanical strength of constructs, the S2 alar-iliac (S2AI) screws have some more advantages. Four Korean fresh-frozen human cadavers were procured.
