We report a modified synthesis route of colloidal gold nanorods (AuNRs) by combining the thermal re-shaping treatment and bi-surfactant modification using hexadecyltrimethylammonium bromide (CTAB) and sodium oleate (NaOL). Aspect ratios down to 1.3 ± 0.1 can be achieved in addition to good monodispersity, uniformity, and chemical stability of the materials. Furthermore, without needing post-treatment, metal ions directly interact with the AuNRs efficiently, allowing rapid and sensitive colorimetric detection of heavy metal ions such as Pb<sup>2+</sup> and Cu<sup>2+</sup> with a low concentration down to 2...

Hepatocellular carcinoma (HCC) is an aggressive neoplastic disease that has been rapidly increasing in incidence. It usually occurs in the background of liver disease, and cirrhosis. Definitive therapy requires surgical resection. However, in majority of cases surgical resection is not tolerated, especially in the presence of portal hypertension and cirrhosis. Orthotopic liver transplant (OLT) in well selected candidates has been accepted as a viable option. Due to a relative scarcity of donors compared to the number of listed recipients, long waiting times are anticipated...

Purpose: To report optical coherence tomography angiography (OCTA) findings pre- and post-thermal laser therapy of a rare, asymptomatic, unilateral, isolated retinal hemangioblastoma. Observations: A 40-year-old asymptomatic Caucasian man was found to have an isolated, unilateral retinal hemangioblastoma after referral for possible retinal hole. Comparison of OCTAs pre- and post-thermal laser therapy demonstrated a significant reduction of blood flow toward and within the lesion, in addition to contraction of the lesion and constriction of the accompanying feeder vessels...

Peripheral arterial disease is a major cause of limb loss and its prevalence is increasing worldwide. As most standard-of-care therapies yield only unsatisfactory outcomes, more options are needed. Recent cell- and molecular-based therapies that have aimed to modulate vascular endothelial growth factor-165 (VEGF165 ) levels have not yet been approved for clinical use due to their uncertain side effects. We have previously reported a heparan sulphate (termed HS7) tuned to avidly bind VEGF165 . Here, we investigated the ability of HS7 to promote vascular recovery in a murine hindlimb vascular ischaemia model...

Background: Magnetic resonance (MR)-guided high-intensity focused ultrasound (HIFU) can palliate metastatic bone pain by periosteal neurolysis. We investigated the value of diffusion-weighted imaging (DWI) for monitoring soft tissue changes adjacent to bone during MR-guided HIFU. We evaluated the repeatability of the apparent diffusion coefficient (ADC) measurement, the temporal evolution of ADC change after sonication, and its relationship with thermal parameters. Methods: Ex-vivo experiments in lamb legs ( n = 8) were performed on a Sonalleve MR-guided HIFU system...

Although EML4-ALK transforming fusion gene is represented in only 8% of non-small cell lung cancer (NSCLC) cases, its expression is partly responsive for the failure of current NSCLC treatments. Preventing secondary mutation of the ALK protein through direct gene manipulation could overcome NSCLC drug resistance. Method: In this study, we developed a gold nanoshell (HAuNs) drug carrier for delivery and selective photo-thermal release of genes that target ALK and microRNA-301 in NSCLC. Additionally, the densely-coated nanoshell adsorbed high amounts of the positively-charged anticancer drug doxorubicin (DOX), generating an exciting multidimensional treatment strategy that includes gene-, thermal- and chemo- therapy...

BACKGROUND: Population aging and lung cancer screening strategies may lead to an increase in detection of early-stage lung cancer in medical inoperable patients. Recent advances in peripheral bronchoscopy have made it a suitable platform for ablation of small peripheral tumors. METHODS: We investigated the tissue-ablative effect of a diode laser bronchoscopically applied by a laser delivery fiber (LDF) with wide aperture on porcine lung parenchyma. Laser was tested ex vivo and in vivo to identify the most effective power settings and LDF...

Sepsis is the largest cause of mortality in thermally injured patients. Traditional SIRS criteria do not aid diagnosis of sepsis in burn centers. Studies have attempted identification of the best indicators of sepsis in the thermal injured patient, but predictive variables are inconsistent across the various studies. Currently, consensus guidelines lack evidential support as to which patients will benefit most from prompt antimicrobial therapy. The purpose of our study was to evaluate novel diagnostic parameters for thermal injured patients with known sepsis and compare these parameters with existing diagnostic criteria...

Overexpression of the prosurvival protein BCL-2 contributes to malignant cell initiation, progression and resistance to treatment. Agents that function as its natural antagonists targeting BCL-2 must provide therapeutic benefit. In SW1990 pancreatic cancer cells, amplified BCL-2 was observed, which was believed to offer advantages for malignant cell survival and lead to poor patient outcome. Using structure-based virtual ligand screening, luteolin was found to be a natural small-molecule inhibitor of BCL-2, which exhibited dose-response proapoptosis activity in a BCL-2 dependent manner in vitro...

Aptamers are single-stranded DNA or RNA which are isolated from synthesized random oligonucleotide library in vitro via systematic evolution of ligands by exponential enrichment (SELEX) and can bind to metal ions, small molecules, carbohydrates, lipids, proteins, and others targets with high affinity and specificity. Aptamers have the advantages of simple preparation, good thermal stability, and low immunogenicity and have great potential in the medical fields such as molecular imaging, biosensing, early diagnosis of diseases, and targeted therapy...

A crucial challenge in nanotherapies is achieving accurate and real-time control of the therapeutic action, which is particularly relevant in local thermal therapies to minimize healthy tissue damage and necrotic cell deaths. Here, a nanoheater/thermometry concept is presented based on magnetoplasmonic (Co/Au or Fe/Au) nanodomes that merge exceptionally efficient plasmonic heating and simultaneous highly sensitive detection of the temperature variations. The temperature detection is based on precise optical monitoring of the magnetic-induced rotation of the nanodomes in solution...

Physiologically relevant phantoms with high reliability are essential for extending the therapeutic applications of high-intensity therapeutic ultrasound. Here we describe a tissue-mimicking phantom capable of quantifying temperature changes and observing non-thermal phenomena by high-intensity therapeutic ultrasound. Using polydiacetylene liposomes, we fabricated agar-based polydiacetylene hydrogel phantoms (PHPs) that not only respond to temperature, but also have acoustic properties similar to those of human liver tissue...

Far red/near infrared (R/NIR) energy is a novel therapy, but its mechanism of action is poorly characterized. Cytochrome c oxidase (Cco) of the mitochondrial electron transport chain is considered the primary photoacceptor for R/NIR to photolyze a putative heme nitrosyl in Cco to liberate free nitric oxide (NO). We previously observed R/NIR light directly liberates NO from nitrosylated hemoglobin and myoglobin, and recently suggested S-nitrosothiols (RSNO) and dinitrosyl iron complexes (DNIC) may be primary sources of R/NIR-mediated NO...

Fluorescence and photoacoustic imaging have different advantages in cancer diagnosis; however, combining effects in one agent normally requires a trade-off as the mechanisms interfere. Here, based on rational molecular design, we introduce a smart organic nanoparticle whose absorbed excitation energy can be photo-switched to the pathway of thermal deactivation for photoacoustic imaging, or to allow opposed routes for fluorescence imaging and photodynamic therapy. The molecule is made of a dithienylethene (DTE) core with two surrounding 2-(1-(4-(1,2,2-triphenylvinyl)phenyl)ethylidene)malononitrile (TPECM) units (DTE-TPECM)...

Treatment of prosthetic joint infections often involves multiple surgeries and prolonged antibiotic administration, resulting in a significant burden to patients and the healthcare system. We are exploring a non-invasive method to eradicate biofilm on metal implants utilizing high-frequency alternating magnetic fields (AMF) which can achieve surface induction heating. Although proof-of-concept studies demonstrate the ability of AMF to eradicate biofilm in vitro, there is a legitimate safety concern related to the potential for thermal damage to surrounding tissues when considering heating implanted metal objects...
