The aim of the study was to verify prognostic value of selected echocardiographic (UKG), impedance cardiography (ICG), and right heart catheterization (RHC) parameters in systolic heart failure (HF). UKG, ICG, and RHC were performed in 46 patients with chronic HF with ejection fraction <35%. During a 1-year follow-up, composite endpoint (death or hospitalization due to HF exacerbation) was achieved by 23 (50.0%) patients. Analysis of receiver operating characteristic (ROC) curves identified UKG parameters: inferior vena cava diameter on inspiration (IVCinsp) >13 mm [area under curve (AUC), 0...

BACKGROUND: Periodontal diseases are pathological inflammatory conditions of multifactorial etiology that develops in response to periodontopathic bacteria. Recently, photodynamic therapy (PDT) has begun to be incorporated as an adjuvant treatment for periodontal diseases. However, the effect of PDT on tissue regeneration is not yet completely clear. This study aimed to analyze the gene expression of basic fibroblast growth factor (bFGF) following PDT in human gingival fibroblasts (HuGu) cells in vitro...

The development of the tyrosine kinase inhibitor Imatinib (IM) represents a milestone breakthrough in CML (Chronic Myeloid Leukemia) treatment. However, it is not curative and patients develop IM resistance. IM resistance has been previously correlated with the emergence of drug-resistant LIC/LSC (Leukemia Initiating Cell/Leukemia Stem Cell) and increased nuclear catenin levels and enhanced Wnt signaling. It has been demonstrated previously that drug resistant CML LIC/LSC can be safely eliminated both in vitro and in vivo via disruption of the CBP/catenin interaction, utilizing the highly biochemically selective small molecule CBP/catenin antagonist ICG-001...

BACKGROUND: Transplantation centers have given much attention to donor availability. However, no reliable quantitative methods have been employed to accurately assess graft quality before transplantation. Here, we report that the indocyanine green (ICG) clearance test is a valuable index for liver grafts. METHODS: We performed the ICG clearance test on 90 brain-dead donors within 6 h before organ procurement between March 2015 and November 2016. We also analyzed the relationship between graft liver function and early graft survival after liver transplantation (LT)...

BACKGROUND: Indocyanine green (ICG) is a near-infrared fluorescent contrast agent, which preferentially accumulates in cancer tissue. The aim of our study was to investigate the role of fluorescence imaging (FI) with ICG (ICG-FI) for detecting peritoneal carcinomatosis (PC) from colorectal cancer (CRC). METHODS: Four CRC patients with PC scheduled for cytoreductive surgery + hyperthermic intraperitoneal chemotherapy were enrolled in this prospective study. At a median time of 50 min after 0...

Indocyanine green (ICG), a Food and Drug Administration (FDA)-approved fluorophore with excitation and emission wavelengths inside the "optical imaging window," has been incorporated into nanocarriers (NCs) to achieve enhanced circulation time, targeting, and real-time tracking in vivo. While previous studies transferred ICG exogenously into NCs, here, a one-step rapid precipitation process [flash nanoprecipitation (FNP)] creates ICG-loaded NCs with tunable, narrow size distributions from 30 to 180 nm. A hydrophobic ion pair of ICG-tetraoctylammonium or tetradodecylammonium chloride is formed either in situ during FNP or preformed then introduced into the FNP feed stream...

BACKGROUND AND IMPORTANCE: During intramedullary lesion surgery, the lesion site and the posterior median sulcus (PMS) should be accurately identified prior to myelotomy to avoid severe injury of the posterior funiculus. However, intramedullary lesions are fundamentally invisible until the myelotomy is performed. Furthermore, the PMS location is frequently unclear due to lesion-induced swelling or distortion of the spinal cord. Intraoperative indocyanine green videoangiography (ICG-VA) followed by FLOW 800 analysis, which shows vascularization of the spinal parenchyma, may provide a solution for these problems in specific cases...

BACKGROUND: Roux-en-Y gastric bypass (RYGB) improves the pathophysiology that contributes to obesity-related nonalcoholic steatohepatitis (NASH). Whether obesity-related fibrosis improves is unclear. We hypothesized that RYGB reverses NASH and fibrosis, and indocyanine green (ICG) clearance provides a sensitive measure for detecting asymptomatic fatty liver disease. METHODS: One hundred six obese adults scheduled for RYGB had preoperative liver function assessed using standard tests and ICG clearance and core liver biopsies obtained during RYGB...

BACKGROUND: Previous attempts at sentinel lymph node (SLN) mapping in colon cancer have been compromised by ineffective tracers and the inclusion of advanced disease. This study evaluated the feasibility of fluorescence detection of SLNs with indocyanine green (ICG) for lymphatic mapping in T1/T2 clinically staged colonic malignancy. METHODS: Consecutive patients with clinical T1/T2 stage colon cancer underwent endoscopic peritumoral submucosal injection of indocyanine green (ICG) for fluorescence detection of SLN using a near-infrared (NIR) camera...

BACKGROUND: Near-infrared (NIR) fluorescence cholangiography by systemic administration of indocyanine green (ICG) enhances the visualization of the biliary tree anatomy. However, the simultaneous enhancement of liver parenchyma can disturb the visualization of critical details. We herein proposed a new technique of NIR cholecystocholangiography by intragallbladder ICG injection to increase the safety during laparoscopic cholecystectomy. METHODS: A total of 46 patients scheduled for laparoscopic cholecystectomy for symptomatic lithiasis (n = 21) or cholecystitis (n = 25) were enrolled...

BACKGROUND: Indocyanine green (ICG) videoangiography can be used to delineate the locations of the cortical vessels just prior to dural opening, allowing safe and optimal dural opening. The present clinical series demonstrates the adjunct use of ICG videoangiography to optimize dural opening for the treatment of various cerebrovascular diseases. METHODS: A total of 45 patients underwent surgery for superficial temporal artery-middle cerebral artery bypass (40), arteriovenous malformation (2), and dural arteriovenous fistula (3) between January 2012 and December 2016...

BACKGROUND: ICG-001, a small molecule, binds CREB-binding protein (CBP) to disrupt its interaction with β-catenin and inhibits CBP function as a co-activator of Wnt/β-catenin-mediated transcription. Given its ability to inhibit Wnt/β-catenin signaling pathway, ICG-001 has been used in some tumor types to exert its anticarcinogenic effect. Here, we examined ICG-001 and its potential role as a therapeutic in gastric cancer (GC). METHODS: The gastric cancer cell lines SGC-7901, MGC-803, BGC-823 and MKN-45 were used in vitro and in vivo...

NIR responsive inorganic hybrid (Ti@GO) was synthesized. It could absorb NIR light and convert it into local hyperthermia and ROS synchronously. Ti@GO was firstly developed as photosensitizer and photothermal agent to realize tumor PTT and PDT. For anti-tumor application, HA was grafted on Ti@GO simultaneously as water solubility improver and tumor targeting moiety. ICG was chose as model drug. Results demonstrated HA-Ti@GO could remarkably improve ICG stability and drug accumulation in 4 T1 cells, to enhance tumor phototherapy efficiency and reduce light-associated side effects...

INTRODUCTION: Bereavement is one of the most common and stressful life experiences one can endure. Typical grief reactions follow a course of recovery in which individuals come to terms with the loss and resume functioning within weeks to months. However, for some, grief remains indefinitely distressing. Complicated Grief (CG) refers to significant chronic impairment that stems from bereavement. Military service members experience myriad factors that likely increase their risk for developing CG...

We evaluated the suitability of 10 candidate internal control genes (ICGs), belonging to different functional classes, namely ACTB, EEF1A1, GAPDH, HPRT1, HMBS, RPS15, RPS18, RPS23, SDHA, and UBC for normalizing the real-time quantitative polymerase chain reaction (qPCR) data of blastocyst-stage buffalo embryos produced by hand-made cloning and in vitro fertilization (IVF). Total RNA was isolated from three pools, each of cloned and IVF blastocysts (n = 50/pool) for cDNA synthesis. Two different statistical algorithms geNorm and NormFinder were used for evaluating the stability of these genes...
