Epithelial-mesenchymal transition (EMT) plays an important role in renal tubulointerstitial fibrosis and TGF-beta1 is the key inducer of EMT. Phosphorylation Smad proteins and/or mitogen-activated protein kinases (MAPK) required for TGF-beta1-induced Because reactive oxygen species (ROS) are involved signaling upstream molecules to MAPK, this study examined ROS MAPK activation EMT rat proximal tubular epithelial cells. Growth-arrested synchronized NRK-52E cells were stimulated with (0.2 20...
Ultrafast optical heating of the electrons in ferrimagnetic metals can result all-optical switching (AOS) magnetization. Here we report quantitative measurements temperature rise GdFeCo thin films during helicity-independent AOS. Critical fluences are obtained as a function initial sample and for laser pulse durations from 55 fs to 15 ps. We conclude that non-equilibrium phenomena necessary AOS, although peak electron does not play critical role. Pump-probe time-resolved experiments show...
A liquid crystal with an azobenzene moiety as a photoactive mesogenic unit is investigated in photoinduced birefringence. Measurements reveal that it possesses large magnitude of birefringence (Δn∼10−2) and the characteristic long-term optical storage. The resulting polarization information can be erased either by heating sample to temperature much higher than glass transition temperature, or method circularly polarized light. mechanism storage discussed this letter.
Activation of type 1 angiotensin (AT(1)) receptors causes hypertension, leading to progressive kidney injury. AT(1) are expressed on immune cells, and previous studies have identified a role for cells in II-dependent hypertension. We, therefore, examined the pathogenesis hypertension by generating bone marrow chimeras with wild-type donors or lacking AT(1A) (BMKO). The 2 groups had virtually identical blood pressures at baseline, suggesting that do not make unique contribution determination...
Abstract A new photoelectrochemical (PEC) biosensor was developed by using carboxyl‐functionalized graphene and CdSe nanoparticles. This sensitive interface then successfully applied to detection of thrombin based on the dual‐quenched effect PEC nanoparticle, which relied electron transfer a bipyridinium relay energy AuNPs. After recognition with an aptamer, nanoparticle removed signal‐on obtained. Moreover, bio‐barcode technique used in preparation could avoid cross‐reaction enhances...
The lateral photovoltaic (LPV) effect has attracted much attention for a long time because of its application in position-sensitive detectors (PSD). Here, we report the ultrafast response LPV amorphous MoS2/Si (a-MoS2/Si) junctions prepared by pulsed laser deposition (PLD) technique. Different orientations built-in field and breakover voltages are observed a-MoS2 films deposited on p- n-type Si wafers, resulting induction positive negative a-MoS2/n-Si a-MoS2/p-Si upon illumination,...
Compared with normal PL, a red shift of upconversion PL spectrum is observed. Time-resolved and TA spectroscopies show FWHM peak position are changed at various times, which suggest the existence more than single excited state.
Many questions are still open regarding the physical mechanisms behind magnetic switching in GdFeCo alloys by single optical pulses. Phenomenological models suggest a femtosecond scale exchange relaxation between sublattice magnetization as driving mechanism for switching. The recent observation of thermally induced using both several picosecond laser pulse well electric current pulses has questioned this previous understanding. This raised question whether or not same mechanics acting at...
Nanoenergetic materials consisting of aluminum nanoparticle (50−200 nm) aggregates termed ALEX plus nitrocellulose (NC) oxidizer are studied by ultrafast spectroscopy following 100 ps laser flash-heating. Thermal conduction calculations used to estimate the initial temperature as a function fluence, and show that initiation ignition occurs result reaction between nearly uniformly heated particles cold NC. The onset light emission Al oxidation near melting point Al, fast violent reactions...
Abstract 1,4‐di(4′‐ N , ‐diphenylaminostyryl)benzene (DPA‐DSB) is a well known compound with large two‐photon absorption (TPA) section and strong fluorescence in solution. However, the ease which it crystallizes results formation of discontinuous crystalline phases during vacuum deposition processes, thereby greatly limiting its applicability solid‐state devices. A cruciform dimer DPA‐DSB, 2,5,2′,5′‐tetra(4′‐ ‐diphenylaminostyryl)biphenyl (DPA‐TSB) reported, wherein two DPA‐DSB molecules are...
Alterations in the cellular architecture, adhesion, and/or loss of glomerular podocytes are causal factors development proteinuria and progression to end-stage renal failure. With use an inducible podocyte differentiation system, it was found that levels PINCH-1, integrin linked kinase (ILK), alpha-parvin, cytoplasmic components cell-extracellular matrix adhesions, were significantly increased during differentiation. Concomitantly, amount PINCH-1-ILK-alpha-parvin complex detected...
Glutathione S -transferase-μ1, GSTM1, belongs to a superfamily of glutathione -transferases that metabolizes broad range reactive oxygen species and xenobiotics. Across species, genetic variants result in decreased expression the Gstm1 gene are associated with increased susceptibility for vascular diseases, including atherosclerosis humans. We previously identified as positional candidate our mapping study renal injury characterized by medial hypertrophy hyperplasia vessels. To determine...
Mesocrystals usually assume properties differing from that of nanocrystals with the same compositions due to their unique morphologies and size region. In work, a simple wet chemical procedure was developed for preparation mesocrystals consisting ZnO nanoparticles. By simply mixing aqueous solutions zinc acetate [Zn(Ac)2], sodium hydroxide (NaOH), tartaric acid (TA) at certain temperatures, composites nanoparticles acid, Zn(OH)2–TA, rod-like morphology were obtained. After being annealed in...
The renin-angiotensin-aldosterone system (RAAS) regulates BP and salt-volume homeostasis. Juxtaglomerular (JG) cells synthesize release renin, which is the first rate-limiting step in RAAS. Intense pathologic stresses cause a dramatic increase number of renin-producing kidney, termed JG cell recruitment, but how this occurs not fully understood. Here, we isolated renal CD44(+) mesenchymal stem (MSC)-like found that they differentiated into JG-like renin-expressing both vitro vivo. Sodium...
