description: Cells, growth factors and scaffolds represent the key elements in tissue engineer- ing strategies. Platelet concentrates are blood derivatives, prepared from patient’s own blood, containing autologous platelets, growth factors and cytokines (1). The use of these autologous preparations, like CGF (Concentrated Growth Factor), repre- sents a promising approach in tissue regeneration and some clinical applications have already been made. Some evidences suggest a pivotal role of trace elements in tis- sue regeneration (2); in particular Silicon plays an important role in bone homeostasis and regeneration (3); so Silicon and CGF could represent an innovative approach for tissue regeneration. In this study, the in vitro effects of Silicon (Sodium Orthosilicate) and CGF, on the proliferation of three different human cell lines (endothelial cells, fibroblasts and osteoblasts) were investigated. Cells were treated with Sodium Ortho- silicate and CGF for 24, 48 and 72 hours respectively. After each incubation period, cell proliferation was evaluated, using the Scepter cell counter; some proliferation markers (Collagen type I, Osteopontin) were evaluated using immunohistochemical methods. In addition we examined the influence of Sodium Orthosilicate and CGF on osteoblasts differentiation. Human osteoblasts were grown until confluence in com- plete growth medium. After 24-72 hours cell confluency, the medium was replaced with osteoblast mineralization medium for 14 days and the osteoblasts differentiation was quantitatively evaluated by immunohistochemistry, using Osteocalcin and ALP, and by Alizarin and Von Kossa stainings. Treatment with Silicon and CGF increases proliferation of all cell lines and promotes osteoblasts differentiation. So, these data could represent a potential and innovative tool for tissue regeneration.

description: In recent years atherosclerosis has become a serious health challenge given its causal association with cardiovascular disease and stroke, which predictably leads to most of the morbidity and mortality worldwide [1]. The mechanism by which in this pathology there is an extensive proliferation of vascular smooth muscle cells (VSMCs) and their migration to the intima remain poorly understood. Recently, low molecular weight heparin (LMWH) has been shown to inhibit the proliferation of VSMCs and, in particular, a kind of these heparins, parnaparin (PNP), acts on the development and clinical course of atherosclerosis in animal models [2].
We hypothesized that PNP might modulate VSMCs migration and thereby decrease vascular remodelling in atherosclerosis. Vascular remodelling was evalu- ated in aortas of an animal model of atherosclerosis, (ApoE)-deficient mice (ApoE -/-) with normal or western diet. We treated animals with PNP to evaluate its pro- tective effect. Thereafter, we evaluated morphological changes and the expression of proteins linked to atherogenesis and atheroprogression in particular an enzyme involved in oxidative stress, iNOS, some inflammatory mediators, such as TNF-α, IL-1 and IL-6, and markers of VSMCs alterations (PAI-1 and TSP1).
Our results demonstrated that PNP downregulates VSMCs proliferation and migration, mediated by PAI-1 and TSP1, and reduces inflammation and oxidative stress in vessels.
These data suggested that LMWH, in particular PNP, could be a theoretically practical tool in the prevention of atherosclerotic vascular modification.

description: We investigate the spatial and temporal features of dense contaminant plumes dynamics in porous materials. Our analysis is supported by novel experimental results concerning pollutant concentration profiles inside a vertical column setup. We describe the experimental methods and elucidate the salient outcomes of the measurements, with focus on miscible fluids in homogeneous saturated media. By resorting to a finite elements approach, we numerically solve the equations that rule the pollutants migration and compare the simulation results with the experimental data. Finally, we qualitatively explore the interfacial dynamics behavior between the dense contaminant plume and the lighter resident fluid that saturates the column.

description: We investigated the 1/f noise of Pt/NiO/Pt capacitors that show unipolar resistance switching. When they were switched from the low to high resistance states, the power spectral density of the voltage fluctuation was increased by approximately five orders of magnitude. At 100 K, the relative resistance fluctuation, SR/R2, in the low resistance state displayed a power law dependence on the resistance R with exponent w = 1.6. This behavior can be explained by percolation theory; however, at higher temperatures or near the switching voltage, SR/R2 becomes enhanced further. This large 1/f noise can be therefore an important problem in the development of resistance random access memory devices.

Papel das células T regulatórias derivadas de tecido adiposo no desenvolvimento de resistência à insulina em obesos
Creators: name: Alliance of Health Research
Publisher: name: Zenodo
Year: 2025
Subjects: Regulatory T cells, adipose tissue, insulin resistance, obesity, chronic inflammation.

description: Obesity is associated with chronic low-grade inflammation and insulin resistance, with adipose tissue-derived regulatory T cells (adTregs) being key components in regulating these processes. This systematic review investigated the role of adTregs in developing insulin resistance in obese individuals, focusing on the immunological and metabolic mechanisms involved. The results indicate that adTreg dysfunction in the adipose tissue of obese individuals is associated with increased local inflammation, activation of pro-inflammatory macrophages (M1), and dysregulation of signaling pathways, such as NF-κB. Modulation of adTregs through pharmacological or genetic interventions has shown promise in reducing inflammation and improving insulin sensitivity in animal models. It is concluded that adTregs play a crucial role in immune and metabolic homeostasis, and their modulation may represent an innovative therapeutic strategy for the treatment of obesity-associated insulin resistance.

description: We systematically reconsider, within an improved "analytic K-matrix model", the extraction of the sigma = f_0(600) and f_0(980) masses, widths and hadronic couplings using new Ke4 = K-->pi-pi e nu_e data on pi-pi phase shift below 390 MeV and different sets of pi-pi--> pi-pi / K-K scatterings data from 400 MeV to 1.4 GeV. Our results are summarized in Tables 1, 2 and 5. In units of MeV, the complex poles are: M_sigma=452(12) - i 260(15) and M_f=981(34) -i 18(11), which are comparable with some recent high-precision determinations and with PDG values. Besides some other results, we find: |g_{sigma K+K-}|/|g_{sigma pi+pi-}|=0.37(6) which confirms a sizeable g_{sigma K+K-} coupling found earlier, and which disfavours a large pi-pi molecule or four-quark component of the sigma, while its broad pi-pi width (relative to the one of the rho-meson) cannot be explained within a \bar qq scenario. The narrow pi-pi width of the f_0(980) and the large value: |g_{f K+K-}|/|g_{f pi+pi-}|=2.59(1.34), excludes its pure (\bar uu+\bar dd) content. A significant gluonium component eventually mixed with \bar qq appears to be necessary for evading the previous difficulties.

description: The aim was to study the anatomical variability of the frontal sinus (FS) drain- age pathway (FSDP), the uncinate process (UP) and the relative air spaces. For this purpose, 14 human heads were endoscopically dissected after a cone-beam CT scan. Several features were assessed both radiologically and in the lab setting. Most of the anatomical features were classified according to the Bent and Kuhn classification modified by Wormald (1). The FSDP was medial to the UP in 82% and lateral in 18% of the cases. The Agger-Nasi Cell (ANC) was found in 100% of cases, a supraorbital pneumatization in 71.5%, a frontal bulla in 14%, a suprabullar cell in 78.5%, a suprab- ullar recess in 23%, an inter-frontal-sinus septal cell in 14%, a concha bullosa in 28.5% of cases. The frontoethmoidal Kuhn cells (K cells) were absent in 32%, type 1 was found in 39%, type 2 in 25%, type 3 in 4% and type 4 in no one case. The medial location of the FSDP respect to the UP was found to correlate with the presence of type 1-4 K cells, while the lateral location significantly correlated with the suprabul- lar recess, which was mostly absent when a suprabullar cell was present. The results of this study should be explained considering the development of the FS based on the description of frontoethmoidal area by Terrier et al. (2) In fact, when the FS arises from a “nasal cell”, the FSDP is medial to the UP and K cells develop, as resulted in the present study; on contrary, when the FS arises from an “orbital cell”, the FSDP is lateral to the UP and no K cells are found. Furthermore, when the FS develops from a “bulla cell”, the pneumatization occurs laterally to the UP. This fact should be explained considering the correlation between the suprabullar recess, which is a sign of “bulla cell” origin, and the lateral location of the FSDP. In conclusion, this data could also support and explain the presence and formation of several other anatomi- cal variations, such as the frontal bulla and the inter-frontal-sinus septal cell.

Black Hole Spins of Radio Sources

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A new approach to constraining or determining the spin of a massive black hole is proposed. A key parameter in the analysis is the dimensionless ratio, r, of the energy released to the mass of the hole. It is shown that the black hole spin, j, may be written as a function of the dimensionless ratio of the black hole spin energy to the black hole mass. When extraction of the black hole spin energy powers an outflow from the hole, the ratio r provides an indication of the black hole spin. The method is applied to a sample of 19 very powerful classical double radio galaxies with a range of size and redshift. The sources are found to have remarkably similar values of r and j, implying that the sources have very similar physical conditions at the time the outflow is generated. A sample of 29 central dominant galaxies is also studied; most of these sources have amorphous or FRI radio structure. The sources have a broad range of ratios r, and correspondingly broad range of black hole spins. The broad range probably results from the fact that each source is observed at a different stage in its lifetime. The intrinsic range of parameters could be as tight as it is for the powerful classical double radio galaxies.

Pulse shape effects on photon-photon interactions in non-linear optical quantum gates

description: Ideally, strong non-linearities could be used to implement quantum gates for photonic qubits by well controlled two photon interactions. However, the dependence of the non-linear interaction on frequency and time makes it difficult to preserve a coherent pulse shape that could justify a single mode model for the time-frequency degree of freedom of the photons. In this paper, we analyze the problem of temporal multi-mode effects by considering the pulse shape of the average output field obtained from a coherent input pulse. It is shown that a significant part of the two photon state transformation can be derived from this semi-classical description of the optical non-linearity. The effect of a non-linear system on a two photon state can then be determined from the density matrix dynamics of the coherently driven system using input-output theory. As an example, the resonant non-linearity of a single two level atom is characterized. The results indicate that the most efficient non-linear effect may not be the widely studied single mode phase shift, but the transfer of one of the photons to an orthogonal mode distinguished by its temporal and spectral properties.

description: We study some of the cosmological imprints of pre-inflationary particles. We show that each such particle provides a seed for a spherically symmetric cosmic defect. The profile of this cosmic defect is fixed and its magnitude is linear in a single parameter that is determined by the mass of the pre-inflationary particle. We study the CMB and peculiar velocity imprints of this cosmic defect and suggest that it could explain some of the large scale cosmological anomalies.

description: A novel experimental scheme has been developed in order to measure the heat capacity of mass selected clusters. It is based on controlled sticking of atoms on clusters. This allows one to construct the caloric curve, thus determining the melting temperature and the latent heat of fusion in the case of first-order phase transitions. This method is model-free. It is transferable to many systems since the energy is brought to clusters through sticking collisions. As an example, it has been applied to Na\_90\^+ and Na\_140\^+. Our results are in good agreement with previous measurements.

description: The digastric muscle is an important surgical landmark. Several anatomical varia- tions of the digastric muscle are reported in literature and the presence of accessory anterior bellies of the muscle are not uncommon (1,2). We reported a symmetrical variation of the digastric muscle that was found during a dissection of the suprahy- oid region. The dissection showed digastric muscles with an accessory anterior belly, which originated from the anterior belly of muscles in proximity and anterior to the intermediate tendon. The accessory bellies of both sides were fused together on the midline and were attached with a unique tendon to the inner surface of the mental symphysis, filling the submental triangle completely. This unreported anatomical var- iation could be considered an additional contribute in the description of the varia- tions of the digastric muscle, with several implications in head and neck pathology, diagnosis and surgery.

description: We report the results from a comprehensive study of 74 ultraluminous infrared galaxies (ULIRGs) and 34 Palomar-Green (PG) quasars within z ~ 0.3$ observed with the Spitzer Infrared Spectrograph (IRS). The contribution of nuclear activity to the bolometric luminosity in these systems is quantified using six independent methods that span a range in wavelength and give consistent results within ~ +/-10-15% on average. The average derived AGN contribution in ULIRGs is ~35-40%, ranging from ~15-35% among "cool" (f_25/f_60 =< 0.2) optically classified HII-like and LINER ULIRGs to ~50 and ~75% among warm Seyfert 2 and Seyfert 1 ULIRGs, respectively. This number exceeds ~80% in PG QSOs. ULIRGs fall in one of three distinct AGN classes: (1) objects with small extinctions and large PAH equivalent widths are highly starburst-dominated; (2) systems with large extinctions and modest PAH equivalent widths have larger AGN contributions, but still tend to be starburst-dominated; and (3) ULIRGs with both small extinctions and small PAH equivalent widths host AGN that are at least as powerful as the starbursts. The AGN contributions in class 2 ULIRGs are more uncertain than in the other objects, and we cannot formally rule out the possibility that these objects represent a physically distinct type of ULIRGs. A morphological trend is seen along the sequence (1)-(2)-(3), in general agreement with the standard ULIRG - QSO evolution scenario and suggestive of a broad peak in extinction during the intermediate stages of merger evolution. However, the scatter in this sequence, implies that black hole accretion, in addition to depending on the merger phase, also has a strong chaotic/random component, as in local AGN. (abridged)

description: Angiogenesis is essential in tissue integration and it is involved in the biological response to biomaterials. Poly-L-lactic acid (PLLA), a synthetic polymer, is utilized as scaffolding to regenerate new tissues. This study investigated the short and long term degradation and the induction of neovascularization of both native PLLA (n-PLLA) and collagen type I soaked PLLA (c-PLLA) porous scaffolds, implanted subcutane- ously in balb/c mice.
The comparative analysis by phase contrast, optical, and scanning electron micros- copy (SEM) of scaffolds 7 and 21 days after implantation showed a mild inflam- matory response at the implant site of c-PLLA scaffold. No significant difference in systemic immune response was detected by hematology analyzer, and by histologi- cal evaluation of lymph node and spleen features. On the contrary, immune reaction was moderate in n-PLLA. Pores of both PLLA networks laying on the muscle fibers were partially infiltrated by appositional collagen/elastin tissue, phagocytic cells, and fibroblast, with respect to the inner side. The presence of numerous and large blood vessels into pores of c-PLLA scaffolds showed an enhancing vascularization rate. These characteristics appeared to be less conspicuous in n-PLLA.
At longer time points (42 and 84 days), there was low difference in inflammato- ry cell presence into scaffold pores and the number of cells infiltrating each implant was significantly decreased. In fact, we did not observe difference in the migration of inflammatory cells into PLLA scaffolds. Polymer degradation was detected in both PLLA networks, but there are no considerable differences, as confirmed by the SEM analysis.
Our results suggest that tissue integration of PLLA is enhanced when it is soaked with collagen, as well as the angiogenic activity on c-PLLA. Furthermore, the colla- gen soaking makes PLLA polymer more suitable for supporting cell attachment, pro- liferation, and function by mimicking the natural extra cellular matrix.

Universal Scaling of the Quantum Conductance of an Inversion-Symmetric Interacting Model

description: We consider quantum transport of spinless fermions in a 1D lattice embedding an interacting region (two sites with inter-site repulsion U and inter-site hopping td, coupled to leads by hopping terms tc). Using the numerical renormalization group for the particle-hole symmetric case, we study the quantum conductance g as a function of the inter-site hopping td. The interacting region, which is perfectly reflecting when td -> 0 or td -> infinity, becomes perfectly transmitting if td takes an intermediate value τ(U,tc) which defines the characteristic energy of this interacting model. When td < tc sqrt(U), g is given by a universal function of the dimensionless ratio X=td/τ. This universality characterizes the non-interacting regime where τ=tc^2, the perturbative regime (U < tc^2) where τcan be obtained using Hartree-Fock theory, and the non-perturbative regime (U > tc^2) where τis twice the characteristic temperature TK of an orbital Kondo effect induced by the inversion symmetry. When td < τ, the expression g(X)=4/(X+1/X)^2 valid without interaction describes also the conductance in the presence of the interaction. To obtain those results, we map this spinless model onto an Anderson model with spins, where the quantum impurity is at the end point of a semi-infinite 1D lead and where td plays the role of a magnetic field h. This allows us to describe g(td) using exact results obtained for the magnetization m(h) of the Anderson model at zero temperature. We expect this universal scaling to be valid also in models with 2D leads, and observable using 2D semi-conductor heterostructures and an interacting region made of two identical quantum dots with strong capacitive inter-dot coupling and connected via a tunable quantum point contact.

description: The chaperonin Hsp60 has multiple functions, among which that of supporting the growth of some type of tumours. HDACi (histone-deacetylase inhibitors) are drugs that regulate gene expression via modulation of epigenetic mechanisms, and induce tumor-cell death. Here, we show that in the tumor cells H292 the HDACi SAHA decreases the intracellular level of Hps60 and promotes its extracellular trafficking by exosomal vesicles. SAHA caused a time- and dose-dependent decrease in cell viabil- ity with a G/2M cell-cycle arrest at 24 h and cell death at 48 h. These effects were accompanied by production of reactive oxygen species and mitochondrial membrane- potential dissipation. The marked decrease in Hsp60 level in SAHA-treated cells was not related to proteasomal degradation since it was not affected by the addition of the proteasome inhibitor MG132. Moreover, the analysis of post-translational modifica- tions of Hsp60 revealed that SAHA treatment induced a modest reduction in the ubiq- uitination of the protein, with no effect on its acetylation state, but did cause a marked increase in tyrosine-nitrated Hsp60. This effect was related to oxidative stress since it was prevented by the anti-oxidant N-acetylcysteine. Most importantly, we showed for the first time that SAHA markedly increases extracellular Hsp60 export via exosomes, which might explain the concomitant decrease of the intracellular chaperonin. Our results suggest that SAHA modifies Hsp60 by nitration and stimulates its extracellu- lar export via exosomes. Since Hsp60-bearing exosomes have been implicated in effec- tive anti-tumour responses, and since elevated intracellular levels of Hsp60 have been related to the arrest of tumour-cell death, our data offer clues to explore what might be as yet uncharacterized mechanisms by which SAHA works as antitumor drug.

description: A Síndrome dos Ovários Policísticos (SOP) é uma desordem endócrina prevalente entre adolescentes, caracterizada por irregularidades menstruais, hiperandrogenismo e presença de ovários policísticos. Estudos recentes sugerem que a exposição a disruptores endócrinos (DEs), como o bisfenol A e ftalatos, pode influenciar a expressão de microRNAs (miRNAs) circulantes, moléculas que regulam a expressão gênica pós-transcricional. Esta revisão sistemática visa analisar os efeitos dos DEs nos perfis de miRNAs circulantes em adolescentes com SOP, buscando compreender os mecanismos moleculares subjacentes e suas implicações clínicas. Foram selecionados 15 estudos que investigaram a relação entre DEs e miRNAs em adolescentes com SOP. Os resultados indicam que a exposição a DEs está associada a alterações na expressão de miRNAs envolvidos na regulação da sensibilidade à insulina, inflamação e função ovariana, sugerindo um papel potencial desses compostos na patogênese da SOP.

description: Low-dimensional boundaries between phases and domains in organic thin films are important in charge transport and recombination. Here, fluctuations of interfacial boundaries in an organic thin film, acridine-9-carboxylic acid (ACA) on Ag(111), have been visualized in real time, and measured quantitatively, using Scanning Tunneling Microscopy. The boundaries fluctuate via molecular exchange with exchange time constants of 10-30 ms at room temperature, yielding length mode fluctuations that should yield characteristic f-1/2 signatures for frequencies less than ~100 Hz. Although ACA has highly anisotropic intermolecular interactions, it forms islands that are compact in shape with crystallographically distinct boundaries that have essentially identical thermodynamic and kinetic properties . The physical basis of the modified symmetry is shown to arise from significantly different substrate interactions induced by alternating orientations of successive molecules in the condensed phase. Incorporating this additional set of interactions in a lattice gas model leads to effective multi-component behavior, as in the Blume-Emery-Griffiths (BEG) model, and can straightforwardly reproduce the experimentally observed isotropic behavior. The general multi-component description allows the domain shapes and boundary fluctuations to be tuned from isotropic to highly anisotropic in terms of the balance between intermolecular interactions and molecule-substrate interactions.

description: 2, 4-Di-O-methyl-L-erythrose is thought to occur in the hydrolysis and periodate oxidation products of polysaccharides. This sugar has now been synthesized from methyl-L-arabofuranoside by tosylation, methylation, detosylation and periodate oxidation. The free sugar was obtained as a sirup and was characterized by the preparation of a crystalline phenylhydrazone and a crystalline p nitrobenzoate.
