Ingia / Ingia

The MA11 human breast-cancer cell line was established with cells isolated from a bone-marrow sample using immunomagnetic beads conjugated to the anti-MUC1 antibody BM-2. The cell line showed a selective preference for metastasising to the brain in athymic nude mice. Following injection of MA11

Mesoporous Europium-Doped Titania Nanoparticles (Eu-MTNs) for Luminescence-Based Intracellular Bio-Imaging.

Ingia / Ingia

Monodisperse and mesoporous europium (Eu)-doped titania nanoparticles (denoted as Eu-MTNs) were prepared by a co-synthesis method with the presence of a cationic surfactant (i.e., CTAB). A maximum loading amount of 8 mol% of Eu could be successfully incorporated into the framework of MTNs. The

Highly luminescent-paramagnetic nanophosphor probes for in vitro high-contrast imaging of human breast cancer cells.

Ingia / Ingia

Rare earth metals (REM) are a group of 17 chemical elements in the periodic table, namely scandium (Sc), yttrium (Y) and the lanthanides. In relation to atomic volume and geological behavior, the lanthanides are further subdivided into light, medium and heavy REM. They find many applications in the

Europium-doped gadolinium sulfide nanoparticles as a dual-mode imaging agent for T1-weighted MR and photoluminescence imaging.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

We present a facile synthesis of europium-doped gadolinium sulfide (GdS:Eu(3+)) opto-magnetic nanoparticles (NPs) via sonochemistry. Their photoluminescence and strong paramagnetic properties enable these NPs to be utilized as an in vitro cell imaging and in vivo T(1)-weighted MR imaging probe. The

Luminescent single-walled carbon nanotube-sensitized europium nanoprobes for cellular imaging.

Ingia / Ingia

Lanthanoid-based optical probes with excitation wavelengths in the ultra-violet (UV) range (300-325 nm) have been widely developed as imaging probes. Efficient cellular imaging requires that lanthanoid optical probes be excited at visible wavelengths, to avoid UV damage to cells. The efficacy of

Lectin nanoparticle assays for detecting breast cancer-associated glycovariants of cancer antigen 15-3 (CA15-3) in human plasma.

Ingia / Ingia

Cancer antigen 15-3 (CA15-3) is widely utilized for monitoring metastatic breast cancer (BC). However, its utility for early detection of breast cancer is severely limited due to poor clinical sensitivity and specificity. The glycosylation of CA15-3 is known to be affected by BC, and therefore it

Nanoparticles target early-stage breast cancer metastasis in vivo.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Despite advances in cancer therapy, treating cancer after it has metastasized remains an unmet clinical challenge. In this study we demonstrate that 100 nm liposomes target triple-negative murine breast-cancer metastases post intravenous administration. Metastatic breast cancer was induced in BALB/c

Nanoparticle-mediated radiopharmaceutical-excited fluorescence molecular imaging allows precise image-guided tumor-removal surgery.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Fluorescent molecular imaging technique has been actively explored for optical image-guided cancer surgery in pre-clinical and clinical research and has attracted many attentions. However, the efficacy of the fluorescent image-guided cancer surgery can be compromised by the low signal-to-noise ratio

Time-resolved fluoroimmunoassay for equol in plasma and urine.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

We present a method for the determination of the isoflavan equol in plasma and urine. This estrogenic isoflavan, which is formed by the action of the intestinal microflora, may have higher biological activity than its precursor daidzein. High urinary excretion of equol has been suggested to be

Determination of prostaglandin metabolites in biological samples by competitive time-resolved fluoroimmunoassay.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

We describe a time-resolved fluoroimmunoassay method for the determination of 13,14-dihydro-15-ketoprostaglandin E2 (PGEM) and 13,14-dihydro-15-ketoprostaglandin F2 alpha (PGFM) in femtomolar ranges. Polyclonal antibodies were raised in rabbits and the antigen was labelled with europium by the

A set of time-resolved fluorescence resonance energy transfer assays for the discovery of inhibitors of estrogen receptor-coactivator binding.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Therapeutic block of estrogen action is typically achieved with conventional antagonists (CAs), compounds that displace estradiol from the estrogen receptor (ER) and induce formation of an ER conformation that cannot bind to coactivator proteins, such as the steroid receptor coactivators (SRCs). As

Structure of estradiol metal chelate and estrogen receptor complex: the basis for designing a new class of selective estrogen receptor modulators.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Selective estrogen receptor modulators, such as 17β-estradiol derivatives bound to metal complexes, have been synthesized as targeted probes for the diagnosis and treatment of breast cancer. Here, we report the detailed 3D structure of estrogen receptor α ligand-binding domain (ERα-LBD) bound with a

Time-resolved fluoroimmunoassay of plasma daidzein and genistein.
