Novel multi-functional polymeric hollow nanocapsules (PHN) based on the crosslinked poly(tert-butyl acrylate) (PtBA) shells were synthesized in a miniemulsion interfacial polymerization via activator generated electron transfer atom transfer radical polymerization (AGET ATRP) technique with
The antitumor activity of a mixture of synthetic N-acetylmuramyl-L-alanyl-D-isoglutamine (MDP) and trehalose-6,6'-dimycolate (TDM) (MDP+TDM) in emulsified form was studied in guinea pigs, each with a syngeneic dermal tumor and microscopically detectable metastases in regional lymph nodes. A single
[structure: see text] Providencin (1) is a naturally occurring cytotoxin isolated from the Caribbean gorgonian octocoral Pseudopterogorgia kallos. Its highly oxygenated hexacyclic structure is based on a previously undescribed bicyclo[12.2.0]hexadecane ring system and was established through
The influence of mineral ol, squalane, squalene, hexadecane, or peanut oil and of the concentration of Tween 80 on the immunotherapeutic capability of emulsified Mycobacterium bovis Bacillus Calmette-Guérin (BCG) cell walls was studied in guinea pigs, each with an established dermal transplant of a
Recently, the somatostatin receptor subtype 2 (SSTR2) selective antagonist sst2-ANT was determined to have a high affinity for SSTR2. Additionally, 111In-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid-sst2-ANT showed high uptake in an SSTR2-transfected, tumor-bearing mouse model and
A series of 21 tobacco smoke components and related compounds werere applied to mouse skin (50 female ICR/Ha Swiss mice/group) three times weekly with a low dose (5 mug/application) of benzo[a]pyrene (B[a]P). The test compounds were of five classes: aliphatic hydrocarbons, aromatic hydrocarbons,
The marine strain Bacillus pumilus strain AAS3, isolated from the Mediterranean sponge Acanthella acuta, produced a diglucosyl-glycerolipid, 1,2-O-diacyl-3-[beta-glucopyranosyl-(1-6)-beta-glucopyranosyl)]glycerol, with 14-methylhexadecanoic acid and 12-methyltetradecanoic acid as the main fatty acid
Polymeric microcapsules with a light-absorbing dye incorporated in their shell can generate vapor microbubbles that can be spatiotemporally controlled by pulsed laser irradiation. These contrast agents of 6-8 μm in diameter can circulate through the vasculature, offering possibilities for ultrasound
Somatostatin receptors (SSTr) are overexpressed in a wide range of neuroendocrine tumors, making them excellent targets for nuclear imaging and therapy, and radiolabeled somatostatin analogues have been investigated for positron emission tomography imaging and radionuclide therapy of SSTr-positive
Epidermal growth factor receptor-2 (EGFR-2) has been implicated in the pathogenesis of breast and other carcinomas. In this report, we tested the ability of a bacteriophage selected peptide KCCYSL, radiolabeled with ⁶⁴Cu, to image EGFR-2 expressing breast tumors in vivo by positron emission
Bone diseases are often a result of increased numbers of osteoclasts, or bone-resorbing cells. Bone metastases are a significant cause of morbidity in many types of cancer. An imaging agent targeting osteoclasts, which are upregulated in osteolytic lesions, may facilitate earlier follow-up in
N-[[4-[[[(2-ethylphenyl)amino]carbonyl]amino]phenyl]acetyl]-N(epsilon)-6-[(2E)-1-oxo-3-(3-pyridinyl-2-propenyl)]-l-lysyl-l-2-aminohexanedioyl-(1-amino-1-cyclohexane)carboxamide (LLP2A) is a high-affinity, high-specificity peptidomimetic ligand (inhibitory concentration of 50% = 2 pM) that binds the
Hollow magnetic polymeric particles (HoMPs) with controllable location of magnetic nanoparticles and functionality of polymeric double shell were fabricated by means of the facile soft templating method in one-pot. During the in situ miniemulsion polymerization, hexadecane, the Ostwald suppressing
The plant, Typhonium flagelliforme (Araceae), commonly known as the "rodent tuber" in Malaysia, is often used as an essential ingredient of herbal remedies for alternative cancer therapies. The hexane extract of this plant was evaluated for cytotoxic activity against in vitro culture on P388 murine
PET with (18)F-labeled arginine-glycine-aspartic acid (RGD) peptides can visualize and quantify α(ν)β(3) integrin expression in patients, but radiolabeling is complex and image contrast is limited in some tumor types. The development of (68)Ga-RGD peptides would be of great utility given the
