Allogeneic hematopoetic stem cell transplantation (allo-HSCT) is a standard treatment for leukemia and other hematologic malignancies. The major complication of allo-HSCT is graft-versus-host-disease (GVHD), a progressive inflammatory illness characterized by donor immune cells attacking the organs of the recipient. Current GVHD prevention and treatment strategies use immune suppressive drugs and/or anti-T cell reagents these can lead to increased risk of infections and tumor relapse. Recent research demonstrated that epigallocatechin gallate (EGCG), a component found in green tea leaves at a level of 25-35% at dry weight, may be useful in the inhibition of GVHD due to its immune modulatory, anti-oxidative and anti-angiogenic capacities...

Atrioventricular septal defects represent a class of congenital cardiac malformations that vary in presentation and management strategy depending upon the severity of the particular lesions present. We present the case of a premature neonate who had a partial atrioventricular septal defect and an accessory mitral (or left atrioventricular) valve leaflet. The latter caused severe left ventricular outflow tract obstruction and severely depressed left ventricular function. We found only one other report of this atrioventricular valve abnormality in association with atrioventricular septal defect...

We present a first direct measurement of the temperature during milling combined with in situ Raman spectroscopy monitoring. The data reveal a low temperature increase due to the mechanical impact and clear temperature increases as a consequence of the reaction heat. Based on the data, temperature rises as postulated in the magma plasma and hot spot theory can be excluded for soft matter milling syntheses.

The authors examine properties of daunorubicin (DNR)-loaded oil-core multilayer nanocapsules prepared via layer-by-layer approach with different polyelectrolyte (PE) coatings such as a standard one (containing polysodium 4-styrenesulphonate/poly(diallyldimethyl-ammonium) chloride) and a polysaccharide-based shell (dextran/chitosan), in regard to the outer layer of poly-l-glutamic acid (PGA) grafted with polyethylene glycol (PGA-g-PEG). The nanocarriers are obtained on a cationic nanoemulsion template (stabilized by dicephalic-type surfactant, N,N-bis[3,30-(trimethylammonio)propyl]-dodecanamide dimethylsulfate) and layered with the PE shell of different thicknesses resulting in average size of 150 nm in diameter (as shown by dynamic light scattering, scanning electron microscopy and cryogenic-transmission electron microscopy, and atomic force microscopy)...

Polycystin-2 (PC2), a calcium-activated cation TRP channel, is involved in diverse Ca(2+) signaling pathways. Malfunctioning Ca(2+) regulation in PC2 causes autosomal-dominant polycystic kidney disease. Here we report two cryo-EM structures of distinct channel states of full-length human PC2 in complex with lipids and cations. The structures reveal conformational differences in the selectivity filter and in the large exoplasmic domain (TOP domain), which displays differing N-glycosylation. The more open structure has one cation bound below the selectivity filter (single-ion mode, PC2SI), whereas multiple cations are bound along the translocation pathway in the second structure (multi-ion mode, PC2MI)...

In the case of oral ingestion of radioactive contaminants, the first contact medium is saliva in the mouth. To gain a first insight into the interaction of radioactive contaminants in human saliva, the speciation of curium (Cm(iii)) and europium (Eu(iii)), i.e., trivalent f-elements, was investigated in different salivary media with time-resolved laser-induced fluorescence spectroscopy (TRLFS). The results indicate that these metal cations are primarily complexed with carbonates and phosphates, forming ternary complexes with a possible stoichiometry of 1 : 1 : 2 (M(iii) : carbonate : phosphate)...

In-resin fluorescence (IRF) protocols preserve fluorescent proteins in resin-embedded cells and tissues for correlative light and electron microscopy, aiding interpretation of macromolecular function within the complex cellular landscape. Dual-contrast IRF samples can be imaged in separate fluorescence and electron microscopes, or in dual-modality integrated microscopes for high resolution correlation of fluorophore to organelle. IRF samples also offer a unique opportunity to automate correlative imaging workflows...

The main objective of this study was to examine the chronic effect of simulated intermittent normobaric hypoxia on blood antioxidant defence capacity in swimmers. The study included 14 male and 14 female competitive swimmers performing part of land training under simulated intermittent normobaric hypoxia (O2 = 15.5%) or in normoxia. Land interval training took place twice per week, with a total of 8 training units during the study, performed with individualized intensity. The activities of blood antioxidant enzymes did not change significantly during the first and last training unit in the hypoxic and normoxic group...

: Although docetaxel (DOX) is the standard of care for advanced prostate cancer (PCa), most patients develop resistance to DOX. Therefore, elucidating the mechanism that underlies resistance to DOX is critical to enhance therapeutic intervention. Mining cDNA microarray from the PC-3 PCa cell line and its DOX-resistant derivative (PC3-TxR) revealed decreased latexin (LXN) expression in the resistant cells. LXN expression was inversely correlated with taxane resistance in a panel of PCa cell lines...

Natural products discovered using agnostic approaches, unlike rationally designed or HTS obtained leads, offer the ability to reveal new biological pathways, and hence, serve as an important vehicle to unveil new avenues in drug discovery. The ritterazine-cephalostatin family of natural products displays robust and potent anti-tumor activities, with sub-nanomolar growth inhibition against multiple cell lines and potent activity in xenograft models. Herein, we use comparative cellular and molecular biological methods to uncover the ritterazine/cephalostatin mode of cytotoxic action (MOA) in human tumor cells...
