Chromosomes of three chalcid wasp species from Brazil, Palmistichus elaeisis Delvare et LaSalle, 1993, Trichospilus diatraeae Cherian et Margabandhu, 1942 (both belonging to the family Eulophidae) and Trichogramma pretiosum Riley, 1879 (Trichogrammatidae), were studied using chromosome morphometrics and base-specific fluorochrome staining. The present study confirmed that these species respecti...

Chromosomes and their behaviour in spermatogenesis in Cimex species (Heteroptera, Cimicidae) from a bat species Myotis emarginatus were studied by using both a conventional staining method and sequence-specific fluorochromes CMA3 and DAPI. Spermatogonial metaphase revealed 28 autosomes, one large Y chromosome and four small X chromosomes. The Y was almost fully C-band positive as well as most t...

4',6-Diamidino-2-phenylindole (DAPI) and Hoechst 33342 (H33342) were used as novel energy relay dyes (ERDs) for an efficient energy transfer to the N719 dye in I(-)/I3(-) based liquid-junction dye-sensitized solar cells (DSSCs). The introduction of the ERDs, either as an additive in the electrolyte or as a co-adsorbent, greatly enhanced the power conversion efficiencies (PCEs), mainly because o...

Platinum based combined chemotherapy have been proved to be the most effective drugs for ovarian cancer treatment, but it is difficult treat cisplatin resistant cancer. Carbobenzoxy-L-leucy-L-Leucyl-L-Leucinal (MG132) a reversible tripeptide aldehyde proteasome inhibitor, purpose of this study was observe effect MG132 on SKOV3 cell and OVCAR-3 expression autophagy apoptosis related factors. The...

Introduction: Burkitt lymphoma (BL) is a rare but highly aggressive B-cell non-Hodgkin lymphoma. BL exhibits characteristic immunophenotype that positive for pan-B cell markers and CD10. The genetic hallmark of the translocation MYC oncogene under regulation an immunoglobulin (IG) heavy or light chain enhancer, resulting in protein overexpression. Notably, by itself not sufficient oncogenesis v...

The purpose of this study was to perform a histological examination blind mole-rat (Nannospalax xanthodon) brain, cerebellum, and spinal cord tissues. Six mole-rats were caught in natural environment, anesthetized with ether, sacrificed. Brain, tissues then removed. All kept 10% formaldehyde for one week, at the end which they subjected routine procedures embedded blocks. Five micron-thick sect...

We discuss the use of fluorescence correlation spectroscopy for the measurement of relatively slow rotations of large macromolecules in solution or attached to other macromolecular structures. We present simulations and experimental results to illustrate the range of rotational correlation times and diffusion times that the technique can analyze. In particular, we examine various methods to ana...
