Abstract Background The US FDA expanded the approval of ceftazidime-avibactam (CAZ-AVI) to include pediatric patients aged ≥ 3 months in 2019. We evaluated vitro activities CAZ-AVI, ceftolozane-tazobactam (C-T), meropenem-vaborbactam (MEM-VAB), imipenem-relebactam (IMI-REL), and comparators against Enterobacterales (ENT; n=2,391) P. aeruginosa (PSA; n=414) isolates causing infection from medica...

Choline is a new positron emission tomography (PET) tracer useful for detection of prostate cancer and metastatic lesions. We report a 70-year-old man with prostate cancer and multiple abdominal, pelvic, and inguinal node metastases. PET scans demonstrated accumulation of 11 C-choline in the primary tumor and lymph node metastases but no accumulation of 18 FFDG. Choline PET/computed tomography ...

Objective: Inhibition of lipid metabolism in breast cancer has been suggested as an effective approach for cancer therapy. Saffron-derived crocetin (Crt) and crocin (Cro) with the known anticancer activity, have shown hypolipidemic effect in diabetes and atherosclerosis. Here, we investigated the effect of Crt/Cro on lipid content in breast cancer. Materials and M...

Chemical Reaction Optimization (CRO) is a recently establishedmetaheuristics for optimization, inspired by the nature of chemical reactions. A chemical reaction is a natural process of transforming the unstable substances to the stable ones. In microscopic view, a chemical reaction starts with some unstable molecules with excessive energy. Themolecules interact with each other through a sequenc...

OBJECTIVE Crocin (Cro) and crocetin (Crt) are two widely known saffron carotenoids, which exert anticancer effects by different mechanisms. Here, we investigated and compared the preventive effect of Cro and Crt at the initiation and promotion stages of breast cancer induction in an animal model. MATERIALS AND METHODS In this experimental study, female Wistar albino rats were injected with th...

The mononuclear, five-coordinate organochromium(V) compound [NBu(4)][CrO(C(6)F(5))(4)] (1) has been obtained as a dark red solid in moderate yield by treatment of the homoleptic organochromium(III) derivative [NBu(4)](2)[Cr(C(6)F(5))(5)] with NO[BF(4)] in CH(2)Cl(2) solution under an oxygen atmosphere. The Cr(V) centre in the [CrO(C(6)F(5))(4)](-) anion shows a square-pyramidal geometry with th...

The influence of slag basicity and CrO content on the viscosity CaO–SiO2–2%MgO–CrO slags has been experimentally determined. decreases with increasing basicity, Cr2O3 content. Both MgO have a basic characteristic acts as network modifier. activation energy further validates these observations. degree polymerization is also found to decrease addition CrO.

BACKGROUND The recent emergence of azithromycin-resistant (AZM-R) N. gonorrhoeae isolates that have coevolved decreased susceptibility to extended-spectrum cephalosporins has caused great concern. Here we investigated the prevalence of decreased susceptibility to ceftriaxone (CRO(D)) in AZM-R isolates and genetically characterized AZM-R isolates in Guangzhou, China from 2009 to 2013. METHODS ...

BACKGROUND Crocin (CRO), chlorogenic acid (CGA), geniposide (GEN), and quercetin (QUE) are all natural compounds with anti-obesity properties, in particular, hypolipidemic effects, which have been widely used for the treatment of obesity-related metabolic diseases. However, it is not yet known whether these compounds interact synergistically. Here, we investigated the effects and molecular mech...

The study aimed to investigate the protective effects of crocin (Cro) against streptozotocin (STZ)-induced oxidative damage in rat striatum. Animals were randomly divided into four groups (five each). Group 1 (sham) were treated with normal saline (2 ml/kg, p.o.). Group 2 (STZ-lesioned or lesion) were injected with ICV-STZ (3 mg/kg bilaterally, on day 1 and 3) and treated with normal saline (2 ...
