REVIEW
S L Bugby, J E Lees, A C Perkins
PURPOSE: This review aims to summarise the hybrid modality radioguidance techniques currently in clinical use and development, and to discuss possible future avenues of research. Due to the novelty of these approaches, evidence of their clinical relevance does not yet exist. The purpose of this review is to inform nuclear medicine practitioners of current cutting edge research in radioguided surgery which may enter standard clinical practice within the next 5-10 years. Hybrid imaging is of growing importance to nuclear medicine diagnostics, but it is only with recent advances in technology that hybrid modalities are being investigated for use during radioguided surgery...

It is well documented that anomalous production of inflammatory proteins linked with most of the toxic expression and genesis of diverse chronic disease including cancer. Diethylnitrosamine (DEN) a well-known hepatotoxin and hepatocarcinogen, can induce oxidative stress and inflammatory reaction in it. Umbelliferone, secondary metabolites, is present in different plants and widely consumed by humans as medicine and food supplements. The aim of the current study was to scrutinize the chemoprotective potential of umbelliferon-α-d-glucopyranosyl-(2(I)→1(II))-α-d-glucopyranoside (UFD) against DEN-induced hepatocellular carcinoma (HCC) in experimental rats...

Modified Wu-Zi-Yan-Zong prescription (MWP), a traditional Chinese medicinal decoction, has possessed the neuroprotective and anti-inflammatory properties. The mechanisms associated with these properties, however, are not completely understood. We designed the experiments to elucidate the antineuroinflammatory property of MWP in BV2 microglia activated by β-amyloid (Aβ), which is a characteristic feature of Alzheimer's disease (AD). The composition of MWP was studied using HPLC. BV2 microglia cells were then treated with Aβ in the presence or absence of MWP...

Despite its important role as a medicinal plant, some studies reported a toxic effect for garlic (Allium sativum) when given in higher doses. Herein, we investigated the possible cardiotoxic effects of high doses of S-methylcysteine (SMC), a water soluble organosulfur compound present in garlic. Rats were orally administered SMC at a low dose (50mg), high dose (150mg) and very high dose (300mg)/kg body weight, or saline (control) for 10days. High and very high doses of SMC resulted in a significant increase in serum cardiac injury biomarkers [aspartate transaminase (AST), lactate dehydrogenase (LDH), creatine kinase (CK) and cardiac troponin T (cTnT)], as well as oxidative stress marker nitric oxide (NO) concentration in heart and a significant decrease in cardiac superoxide dismutase (SOD) activity...

The androgen receptor (AR) plays important roles in prostate cancer development and prostate tumor growth. After binding to androgens, AR functions as a nuclear receptor and translocates to the nucleus to bind to specific AR-binding sites (ARBSs). AR regulates epigenetic factor recruitments to activate its downstream signaling. Although androgen deprivation therapy (ADT) is initially useful for prostate cancer patients, most patients eventually show resistance with hormone-refractory prostate cancers (HRPCs) or castration-resistant prostate cancers (CRPCs)...

The great progress of genetics research, during 2015-2017, will certainly influence all medical specialties including nuclear medicine. In nuclear medicine there are still problems to solve as to differentiate between infection, inflammation and cancer etc. Furthermore, in dosimetry and radiation protection there are worldwide problems. It has been reported that (64) Cu-cetuximab immune-PET represented EGFR expression levels in ESCC tumors and that (177) Lu-cetuximab radioimmunotherapy effectively inhibited the tumor growth...

Although it is essential in critical care medicine, mechanical ventilation often results in ventilator‑induced lung injury (VILI). Treating mice with lipopolysaccharide has been reported to upregulate the expression of miR‑127, which has been implicated in the modulation of immune responses. However, the putative roles of miR‑127 during the development of VILI have yet to be elucidated. The present study demonstrated that challenging mice with mechanical ventilation for 6 h significantly upregulated the expression of miR‑127 in bronchoalveolar lavage fluid, serum and lung tissue samples...
