Bile acids (BAs), which are synthesized in the liver and cycled in the enterohepatic circulation, have been recognized as signaling molecules by activating their receptors in the intestine and liver. Serum taurine-conjugated BAs have been shown to be elevated after bariatric surgeries, although the postoperative BA profiles within the enterohepatic circulation have not been investigated. Clarification of these profiles could help explain the mechanisms by which bariatric surgery leads to BA profile alterations and subsequent metabolic effects...

Detectors with depth encoding capability and good timing resolution are required to develop a high-performance whole-body or total-body PET scanner. In this work, depth-encoding PET detectors using light sharing between two discrete crystals and single-ended readout with SiPMs were manufactured and evaluated. The detectors consisted of two unpolished LYSO crystals of 3×3×20 mm3 with different coupling materials between them and were read out by Hamamatsu 3×3 mm2 SiPMs with one-to-one coupling. The ratio of the energy of one SiPM to the total energy of two SiPMs is used to measure the depth of interaction (DOI)...

Small-angle neutron scattering (SANS) on nuclei of chicken erythrocytes demonstrates the cubic dependence of the scattering intensity Q^{-3} in the range of momentum transfer Q∈10^{-3}-10^{-2}nm^{-1}. Independent spin-echo SANS measurements give the spin-echo function, which is well described by the exponential law in a range of sizes (3×10^{2})-(3×10^{4}) nm. Both experimental dependences reflect the nature of the structural organization of chromatin in the nucleus of a living cell, which corresponds to the correlation function γ(r)=ln(ξ/r) for r<ξ, where ξ=(3...

MicroRNAs (miRNAs) have been extensively studied over the decades and have been proposed as potential molecular targets for cancer treatment. Studies have shown that miR-378 participates in numerous biological processes in various cancers; whereas miR-1827 has only been reported in pediatric glioma. The mechanism of how miRNAs modulate lung cancer metastasis remains unclear. Our previous study demonstrated that miR-378 is up-regulated while miR-1827 is down-regulated in high invasive lung cancer sub-cell lines, and their biological functions have been described...

UVB has been shown to stimulate the generation of ROS, which subsequently results in activation of various intracellular signaling pathways and transcription factors (AP-1, NF-κB), These transcription factors are regulated by MAPKs, which increase cytokine and MMP expression. We examined the preventive effects of reversine on MMP-1 and -3 expressions in NHEKs and NHDFs exposed to UVB irradiation. Also, we confirmed that reversine decreased pro-inflammatory cytokine expression in NHEKs. The mechanism underlying the MMP-inhibitory effects of reversine occurred via the suppression of UVB-induced ROS generation and MAPK/AP-1 activation...

Endovascular treatment and prognosis of intracranial aneurysms are based on size and volume, which demand more accurate neuroimaging techniques. Aneurysm volume calculation is important to choose endovascular treatment modalities and packing density calculation. Of all these methods, it remains unknown which one is the most accurate to calculate aneurysm volume. The objective of this study is to compare the accuracy of three angiography-based versus three tomographic-based methods which calculate aneurysm volume...

Diabetes, a disease that constitutes a syndrome, is growing more quickly in societies with precarious living and working conditions. Daily care practices are fundamental in preventing it from progressing. This work shows the heuristic and interpretative value and the explanatory potential of an ethnographic approach and a gender perspective in the analysis of care practices in a group of elder adults living with type 2 diabetes. The research was carried out with diabetes group participants and health professionals in a primary healthcare center in José León Suárez, municipality of San Martín, province of Buenos Aires, during the period 2013-2016...

Previous observations indicated that C3G (RAPGEF1) promotes α-granule release, evidenced by the increase in P-selectin exposure on the platelet surface following its activation. The goal of the present study is to further characterize the potential function of C3G as a modulator of the platelet releasate and its implication in the regulation of angiogenesis. Proteomic analysis revealed a decreased secretion of anti-angiogenic factors from activated transgenic C3G and C3G∆Cat platelets. Accordingly, the secretome from both transgenic platelets had an overall pro-angiogenic effect as evidenced by an in vitro capillary-tube formation assay with HUVECs (human umbilical vein endothelial cells) and by two in vivo models of heterotopic tumor growth...

The aim of this work was to evaluate the performance of a novel self-autonomous reactor technology (capable of working with solar irradiation and artificial UV light) for water treatment using aniline as model compound. This new reactor design overcomes the problems of the external mass transfer effect and the accessibility to photons occurring in traditional reaction systems. The UV-light source is located inside the rotating quartz drums (where TiO2 is immobilized), allowing light to easily reach the water and the TiO2 surface...

The resurgence of haploidentical stem cell transplantation (HaploSCT) over the last decade is one of the most important advances in the field of hematopoietic stem cell transplantation (HSCT). The modified platforms of T cell depletion either ex vivo (CD34+ selection, 'mega-dose' of purified CD34+ cells, or selective depletion of T-cells) or newer platforms of in vivo depletion of T cells, with either post-transplant high-dose cyclophosphamide (PTCy) or intensified immune suppression, have contributed to better outcomes, with survival that is similar to HLA-match donor transplantation...
