Anti-cancer properties of terpenoids isolated from Rhizoma Curcumae--a review.

Ethnopharmacological Relevance: Rhizoma Curcumae is a popular type of traditional Chinese medicine whose essential oils are widely used in the treatment of cancer in China. This review aims to systematically summarize and analyze the anti-cancer properties of terpenoids, the main components of essential oils in Rhizoma Curcumae, and thus enable the development of new anti-cancer drugs.

Materials And Methods: Information on the recent progress of anti-cancer studies on terpenoids isolated from Rhizoma Curcumae, including β-elemene, δ-elemene, furanodiene, furanodienone, curcumol, and germacrone, was gathered and analyzed.

Comparative evaluation of Logan and relative-equilibrium graphical methods for parametric imaging of dynamic [18F]FDDNP PET determinations.

Unlabelled: Logan graphical analysis with cerebellum as reference region has been widely used for the estimation of the distribution volume ratio (DVR) of [(18)F]FDDNP as a measure of amyloid burden and tau deposition in human brain because of its simplicity and computational ease. However, spurious parametric DVR images may be produced with shorter scanning times and when the noise level is high. In this work, we have characterized a relative-equilibrium-based (RE) graphical method against the Logan analysis for parametric imaging and region-of-interest (ROI) analysis.

Integrating factor analysis and a transgenic mouse model to reveal a peripheral blood predictor of breast tumors.

Background: Transgenic mouse tumor models have the advantage of facilitating controlled in vivo oncogenic perturbations in a common genetic background. This provides an idealized context for generating transcriptome-based diagnostic models while minimizing the inherent noisiness of high-throughput technologies. However, the question remains whether models developed in such a setting are suitable prototypes for useful human diagnostics.

Anti-cancer natural products isolated from chinese medicinal herbs.

In recent years, a number of natural products isolated from Chinese herbs have been found to inhibit proliferation, induce apoptosis, suppress angiogenesis, retard metastasis and enhance chemotherapy, exhibiting anti-cancer potential both in vitro and in vivo. This article summarizes recent advances in in vitro and in vivo research on the anti-cancer effects and related mechanisms of some promising natural products. These natural products are also reviewed for their therapeutic potentials, including flavonoids (gambogic acid, curcumin, wogonin and silibinin), alkaloids (berberine), terpenes (artemisinin, β-elemene, oridonin, triptolide, and ursolic acid), quinones (shikonin and emodin) and saponins (ginsenoside Rg3), which are isolated from Chinese medicinal herbs.

Phenotypic characterization of human colorectal cancer stem cells.

Recent observations indicate that, in several types of human cancer, only a phenotypic subset of cancer cells within each tumor is capable of initiating tumor growth. This functional subset of cancer cells is operationally defined as the "cancer stem cell" (CSC) subset. Here we developed a CSC model for the study of human colorectal cancer (CRC).

Possible interaction between MAOA and DRD2 genes associated with antisocial alcoholism among Han Chinese men in Taiwan.

Both monoamine oxidase A (MAOA) and dopamine D(2) receptor (DRD2) genes have been considered as candidate genes for antisocial personality disorder with alcoholism (Antisocial ALC) [Parsian, A., 1999. Sequence analysis of exon 8 of MAO-A gene in alcoholics with antisocial personality and normal controls.

Measurement of the lifetime difference in the B0(s) system.

We present a study of the decay B0(s) --> J/psiphi. We obtain the CP-odd fraction in the final state at time zero, Rperpendicular = 0.16 +/- 0.

Measurement of the lifetime difference between Bs mass eigenstates.

We present measurements of the lifetimes and polarization amplitudes for B(0)(s)-->J/psiphi and B(0)(d)-->J/psiK(*0) decays. Lifetimes of the heavy and light mass eigenstates in the B(0)(s) system are separately measured for the first time by determining the relative contributions of amplitudes with definite CP as a function of the decay time. Using 203+/-15 B(0)(s) decays we obtain tau(L) = (1.

[Intranasal or intragastric vaccination of mice with recombinant Schistosoma japonicum ferritin induces immune protection against challenge infection].

Objective: To test the immune protection against challenge infection in mice vaccinated intranasally or intragastrically with recombinant Schistosoma japonicum (S.j) Ferritin (rSjFer).

Methods: Mice were divided into 8 groups each with 10 mice.

Observation of large CP violation in the neutral B meson system.

We present a measurement of the standard model CP violation parameter sin2 phi(1) based on a 29.1 fb(-1) data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. One neutral B meson is fully reconstructed as a J/psi K(S), psi(2S)K(S), chi(c1)K(S), eta(c)K(S), J/psi K(L), or J/psi K(*0) decay and the flavor of the accompanying B meson is identified from its decay products.

Measurement of the CP violation parameter sin2 phi(1) in B(0)(d) meson decays.

We present a measurement of the standard model CP violation parameter sin2 phi(1) (also known as sin2beta) based on a 10.5 fb(-1) data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric e(+)e(-) collider. One neutral B meson is reconstructed in the J/psiK(S), psi(2S)K(S), chi(c1)K(S), eta(c)K(S), J/psiK(L), or J/psipi(0) CP-eigenstate decay channel and the flavor of the accompanying B meson is identified from its charged particle decay products.

Characterization of recombinant thioesterase and acyl carrier protein domains of chicken fatty acid synthase expressed in Escherichia coli.

Fatty acid synthase of animal tissue is a multifunctional enzyme comprised of two identical subunits, each containing seven partial activities and a site for the prosthetic group, 4'-phosphopantetheine (acyl carrier protein). We have recently isolated cDNA clones of chicken fatty acid synthase coding for the dehydratase, enoyl reductase, beta-ketoacyl reductase, acyl carrier protein, and thioesterase domains (Chirala, S.S.

Preparation and characterization of heat-sensitive immunoliposomes.

Immunoliposomes able to bind specifically to target cells and to release their encapsulated contents upon brief heating were prepared. Monoclonal anti-H2Kk was covalently derivatized with palmitic acid by the method of Huang, A. et al.
