description: We investigate transverse hadron spectra from proton+proton, deuteron+Au and Au+Au collisions at sqrt{s}=200 GeV and 17.3 GeV within the Hadron-String-Dynamics (HSD) approach which is based on quark, diquark, string and hadronic degrees of freedom as well as Pythia calculations for the high pT spectra. The comparison to experimental data on transverse mass spectra from p+p, d+Au and Au+Au reactions shows that pre-hadronic effects are responsible for both the hardening of the spectra for low transverse momenta (Cronin effect) as well as the suppression of high pT hadrons. The interactions of formed hadrons are found to be negligible in central Au+Au collisions at sqrt{s}=200 GeV for pT\geq 6 GeV/c, but have some importance for the shape of the ratio R_{AA} at lower pT values (\leq 6 GeV/c). The large suppression seen experimentally is attributed to the inelastic interactions of 'leading' pre-hadrons with the dense environment, which could be partly of colored partonic nature in order to explain the large attenuation seen in most central Au+Au collisions.

Pathway of ADP-stimulated ADP release and dissociation of tethered kinesin from microtubules. Implications for the extent of processivity.

description: Kinesin binds to microtubules with half-site ADP release to form a tethered intermediate with one attached head without nucleotide and one tethered head that retains its bound ADP. For DKH405 containing amino acid residues 1-405 of Drosophila kinesin, release of the remaining ADP from the tethered head is slow (0.05 s(-1)), but release is accelerated by added ADP or ATP. The maximum rate of ADP-stimulated dissociation of tethered DKH405 from the microtubule is approximately 12 s(-1) as determined by turbidity. Parallel measurements of ADP-stimulated release of 2'(3')-O-(N-methylanthraniloyl)-ADP (mantADP) from the tethered intermediate by fluorescence indicate that the reaction is biphasic with a fast phase that occurs at a rate that is similar to dissociation. The rate of the slow phase is dependent on the concentrations of salt and microtubules and is equal in each case to the rate for bimolecular stimulation of ADP release by microtubules as measured independently. These results are consistent with a scheme in which the fast phase, with approximately one-third of the total amplitude change, is due to ADP-stimulated release of mantADP from the tethered intermediate at approximately 6 s(-1). This direct release of mantADP continues until terminated by dissociation of DKH405 from the microtubule at approximately 12 s(-1). The majority of the amplitude change thus occurs through bimolecular recombination of DKH405.mantADP with microtubules following initial dissociation. Analysis of a simple scheme indicates that hydrolysis of ATP at the attached head before the tethered head can release its ADP and become tightly bound may be the principal limitation to processivity.

description: We present results of specific heat, electrical resistance, and magnetoresistivity measurements on single crystals of the heavy-fermion superconducting alloy Ce$_{0.91}$Yb$_{0.09}$CoIn$_5$. Non-Fermi liquid to Fermi liquid crossovers are clearly observed in the temperature dependence of the Sommerfeld coefficient $γ$ and resistivity data. Furthermore, we show that the Yb-doped sample with $x=0.09$ exhibits universality due to an underlying quantum phase transition without an applied magnetic field by utilizing the scaling analysis of $γ$. Fitting of the heat capacity and resistivity data based on existing theoretical models indicates that the zero-field quantum critical point is of antiferromagnetic origin. Finally, we found that at zero magnetic field the system undergoes a third-order phase transition at the temperature $T_{c3}\approx 7$ K.

description: Liangshan cattle are a very small indigenous breed with adult weight of less than 300 Kg and have been mainly distributed in the Liangshan Yi Autonomous Prefecture of Southwestern Sichuan, China. Due to its long-term adaptation to local environments, Liangshan cattle is a valuable genetic resource and should be paid with more attentions. However, the genetic diversity of Liangshan cattle have not been specifically investigated yet, which would be required when designing the appropriate conservation and utilization programs. In this study, we successfully employed the restriction-site-associated DNA sequencing (RAD-seq) approach to explore a total of 84,854 genome-wide and high-confidence SNPs of Liangshan cattle. All these SNPs were evenly distributed through all chromosomes with an average of 98 SNPs per 1-Mb region. The nucleotide diversity, expected heterozygosity, polymorphism information content of Liangshan cattle were 0.227, 0.223 and 0.183, respectively. Furthermore, there was no obvious difference on the genetic diversity among the three studied geographical populations. In conclusion, we provided a list of SNPs that could be used in the follow-up studies for Liangshan cattle and revealed a relatively high genetic variation in this gene pool.

description: The frequencies and phases of emission from extra-solar sources measured by Earth-bound observers are modulated by the motions of the observer with respect to the source, and through relativistic effects. These modulations depend critically on the source's sky-location. Precise knowledge of the modulations are required to coherently track the source's phase over long observations, for example, in pulsar timing, or searches for continuous gravitational waves. The modulations can be modelled as sky-location and time-dependent time delays that convert arrival times at the observer to the inertial frame of the source, which can often be the Solar system barycentre. We study the use of reduced order modelling for speeding up the calculation of this time delay for any sky-location. We find that the time delay model can be decomposed into just four basis vectors, and with these the delay for any sky-location can be reconstructed to sub-nanosecond accuracy. When compared to standard routines for time delay calculation in gravitational wave searches, using the reduced basis can lead to speed-ups of 30 times. We have also studied components of time delays for sources in binary systems. Assuming eccentricities $< 0.25$ we can reconstruct the delays to within 100s of nanoseconds, with best case speed-ups of a factor of 10, or factors of two when interpolating the basis for different orbital periods or time stamps. In long-duration phase-coherent searches for sources with sky-position uncertainties, or binary parameter uncertainties, these speed-ups could allow enhancements in their scopes without large additional computational burdens.

description: We compare the characteristics of two types of patterns obtained with two azopolymer materials: a Gaussian random pattern and a quasi-random grating pattern. The surface structurations have been obtained with a simple bottom-up technique by illuminating azopolymer thin films with a single laser beam. We demonstrate the interesting generated properties of these two surfaces. In particular, the surface with quasi-random gratings can address beam splittings for light coupling in different directions in an ultra-thin film. We use these two surfaces as a mold and replicate them on a transparent elastomeric material and we demonstrate a very good light entrapment. We also show that the efficiency of light trapping is 20% better with the quasi-random gratings than with the Gaussian random surface, and is close to 40%.

Theoretical approaches to particle propagation and acceleration in turbulent intergalactic medium

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Intercluster medium is expected to be turbulent with turbulence being superAlfvenic at large scales. Magnetic fields substantially modify the turbulent cascade when the turbulence reaches the scales at which the fluctuation velocity gets less than the Alfven velocity. At those scales it is possible to consider three cascades, of fast, slow and Alfven modes with little energy exchange between them. As Alfvenic and slow modes are anisotropic they marginally scatter and accelerate cosmic rays, while fast modes dominate the processes. However, in the presence of cosmic rays the turbulence is modified as cosmic rays transfer the energy of compressible motions (i.e. slow and fast modes) from large scales to the scale of cosmic ray Larmor radius. This results in generation of a new small-scale Alfvenic component which is not a part of the ordinary MHD cascade. This component does scatter and accelerate cosmic rays. In addition, magnetic reconnection in turbulent medium accelerates cosmic rays. The complexity of the intracluster turbulence calls for observational studies. A new technique Velocity Coordinate Spectrum (VCS) is particularly promising for studies of velocity fluctuations with a new generation of X-ray observatories.

description: The intracellular environment imposes a variety of constraints on biochemical reaction systems that can substantially change reaction rates and equilibria relative to an ideal solution-based environment. One of the most notable features of the intracellular environment is its dense macromolecular crowding, which, among many other effects, tends to strongly enhance binding and assembly reactions. Despite extensive study of biochemistry in crowded media, it remains extremely difficult to predict how crowding will quantitatively affect any given reaction system due to the dependence of the crowding effect on numerous assumptions about the reactants and crowding agents involved. We previously developed a two dimensional stochastic off-lattice model of binding reactions based on the Green's function reaction dynamics method in order to create a versatile simulation environment in which one can explore interactions among many parameters of a crowded assembly system. In the present work, we examine interactions among several critical parameters for a model dimerization system: the total concentration of reactants and inert particles, the binding probability upon a collision between two reactant monomers, the mean time of dissociation reactions, and the diffusion coefficient of the system. Applying regression models to equilibrium constants across parameter ranges shows that the effect of the total concentration is approximately captured by a low-order nonlinear polynomial model, while the other three parameter effects are each accurately captured by a linear model. Furthermore, validation on tests with multi-parameter variations reveals that the effects of these parameters are separable from one another over a broad range of variation in all four parameters. The simulation work suggests that predictive models of crowding effects can accommodate a wider variety of parameter variations than prior theoretical models have so far achieved.

description: In antiferromagnetic (AFM) thin films, broken inversion symmetry or coupling to adjacent heavy metals can induce Dzyaloshinskii-Moriya (DM) interactions. Knowledge of the DM parameters is essential for understanding and designing exotic spin structures, such as hedgehog Skyrmions and chiral Néel walls, which are attractive for use in novel information storage technologies. We introduce a framework for computing the DM interaction in two-dimensional Rashba antiferromagnets. Unlike in Rashba ferromagnets, the DM interaction is not suppressed even at low temperatures. The material parameters control both the strength and the sign of the interfacial DM interaction. Our results suggest a route toward controlling the DM interaction in AFM materials by means of doping and electric fields.

Intermittency of Magnetohydrodynamic Turbulence: Astrophysical Perspective

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Intermittency is an essential property of astrophysical fluids, which demonstrate an extended inertial range. As intermittency violates self-similarity of motions, it gets impossible to naively extrapolate the properties of fluid obtained computationally with relatively low resolution to the actual astrophysical situations. In terms of Astrophysics, intermittency affects turbulent heating, momentum transfer, interaction with cosmic rays, radio waves and many more essential processes. Because of its significance, studies of intermittency call for coordinated efforts from both theorists and observers. In terms of theoretical understanding we are still just scratching a surface of a very rich subject. We have some theoretically well justified models that are poorly supported by experiments, we also have She-Leveque model, which could be vulnerable on theoretical grounds, but, nevertheless, is well supported by experimental and laboratory data. I briefly discuss a rather mysterious property of turbulence called ``extended self-similarity'' and the possibilities that it opens for the intermittency research. Then I analyze simulations of MHD intermittency performed by different groups and show that their results do not contradict to each other. Finally, I discuss the intermittency of density, intermittency of turbulence in the viscosity-dominated regime as well as the intermittency of polarization of Alfvenic modes. The latter provides an attractive solution to account for a slower cascading rate that is observed in some of the numerical experiments. I conclude by claiming that a substantial progress in the field may be achieved by studies of the turbulence intermittency via observations.

description: We show that in generic no-scale models in string theory, the flat, expanding cosmological evolutions found at the quantum level can be attracted to a "quantum no-scale regime", where the no-scale structure is restored asymptotically. In this regime, the quantum effective potential is dominated by the classical kinetic energies of the no-scale modulus and dilaton. We find that this natural preservation of the classical no-scale structure at the quantum level occurs when the initial conditions of the evolutions sit in a subcritical region of their space. On the contrary, supercritical initial conditions yield solutions that have no analogue at the classical level. The associated intrinsically quantum universes are sentenced to collapse and their histories last finite cosmic times. Our analysis is done at 1-loop, in perturbative heterotic string compactified on tori, with spontaneous supersymmetry breaking implemented by a stringy version of the Scherk-Schwarz mechanism.

description: Lakes are inestimable renewable natural resources that are under significant
 pressure by human activities. Monitoring lakes regularly is necessary to understand
 their dynamics and the drivers of these dynamics to support effective management.
 Remote sensing by satellite sensors offers a significant opportunity to increase the
 spatiotemporal coverage of environmental monitoring programs for inland waters.
 Lake color is a water quality attribute that can be remotely sensed and is independent
 of the sensor specifications and water type. In this study we used the Multispectral
 Imager (MSI) on two Sentinel-2 satellites to determine the color of water of 170
 Italian lakes during two periods in 2017. Overall, most of the lakes appeared blue in
 spring and green-yellow in late summer, and in particular, we confirm a blue-water
 status of the largest lakes in the subalpine ecoregion. The color and its seasonality are
 consistent with characteristics determined by geomorphology and primary drivers
 of water quality. This suggests that information about the color of the lakes can
 contribute to synoptic assessments of the trophic status of lakes. Further ongoing
 research efforts are focused to extend the mapping over multiple years.

description: The primary mesenchyme cells (PMCs) of the sea urchin embryo undergo a dramatic sequence of morphogenetic behaviors that culminates in the formation of the larval endoskeleton. Recent studies have identified components of a gene regulatory network that underlies PMC specification and differentiation. In previous work, we identified novel gene products expressed specifically by PMCs (Illies, M.R., Peeler, M.T., Dechtiaruk, A.M., Ettensohn, C.A., 2002. Identification and developmental expression of new biomineralization proteins in the sea urchin, Strongylocentrotus purpuratus. Dev. Genes Evol. 212, 419-431). Here, we show that one of these gene products, P16, plays an essential role in skeletogenesis. P16 is not required for PMC specification, ingression, migration, or fusion, but is essential for skeletal rod elongation. We have compared the predicted sequences of P16 from two species and show that this small, acidic protein is highly conserved in both structure and function. The predicted amino acid sequence of P16 and the subcellular localization of a GFP-tagged form of the protein suggest that P16 is enriched in the plasma membrane. It may function to receive signals required for skeletogenesis or may play a more direct role in the deposition of biomineral. Finally, we place P16 downstream of Alx1 in the PMC gene network, thereby linking the network to a specific "effector" protein involved in biomineralization.

description: We analyse supersymmetric contributions to B_s mixing and their impact on mixing-induced CP asymmetries, using the mass insertion approximation. We discuss in particular the correlation of SUSY effects in the CP asymmetries of B_s -> J/psi phi and B_d -> phi K_S and find that the mass insertions dominant in B_s mixing and B_d -> phi K_S are (delta_{23}^d)_{LL, RR} and (delta_{23}^d)_{LR, RL}, respectively. We show that models with dominant (delta_{23}^d)_{LR, RL} can accomodate a negative value of S_{phi K_S}, in agreement with the BELLE measurement of that observable, but yield a B_s mixing phase too small to be observed. On the other hand, models with dominant (delta_{23}^d)_{LL, RR} predict sizeable SUSY contributions to both Delta M_s and the mixing phase, but do not allow the asymmetry in B_d -> phi K_S to become negative, except for small values of the average down squark mass, which, in turn, entail a value of Delta M_s too large to be observed at the Tevatron and the LHC. We conclude that the observation of B_s mixing at hadron machines, together with the confirmation of a negative value of S_{phi K_S}, disfavours models with a single dominant mass insertion.

description: We study leptogenesis in two seesaw models where maximal atmospheric neutrino mixing and $U_{e3} = 0$ result from symmetries. Salient features of those models are the existence of three Higgs doublets and a twofold degeneracy of the neutrino Dirac mass matrix. We find that in those models both leptogenesis and neutrinoless double beta decay depend on the same unique Majorana phase. Leptogenesis can produce a baryon asymmetry of the universe of the right size provided the mass of the heavy neutrino whose decays generate the lepton asymmetry is in the range $10^{11}$--$10^{12} \mathrm{GeV}$. Moreover, in these models, leptogenesis precludes an inverted neutrino mass spectrum since it requires the mass of the lightest neutrino to be in the range $10^{-3}$--$10^{-2} \mathrm{eV}$.

For the atmospheric neutrino mass-squared difference we find that in the normal (inverted) mass hierarchy the more tangentially-propagating (radially-propagating) neutrinos and antineutrinos can initiate collective, simultaneous medium-enhanced flavor conversion of these particles across broad ranges of energy and propagation direction. Accompanying alterations in neutrino/antineutrino energy spectra and/or fluxes could affect supernova nucleosynthesis and the expected neutrino signal.

We find that a necessary condition is that $\mathcal{M}_7$ is a $\mathrm{U}(1)$-fibration over a balanced manifold. We subsequently classify all $\mathcal{N}=(2,2)$ solutions where $\mathcal{M}_7$ satisfies the stronger condition of being a $\mathrm{U}(1)$-fibration over a Kahler manifold. We compute the BPS spectrum of all the backgrounds in this classification. We assign a natural dual CFT to the backgrounds and confirm that the BPS spectra agree, thus providing evidence in favour of the proposal.

description: It is often possible to obtain a detailed understanding of the forward steps in ATP hydrolysis because they are thermodynamically favored and usually occur rapidly. However, it is difficult to obtain the reverse rates for ATP resynthesis because they are thermodynamically disfavored and little of their product, ATP, accumulates. Isotopic exchange reactions provide access to these reverse reactions because isotopic changes accumulate over time due to multiple reversals of hydrolysis, even in the absence of net resynthesis of significant amounts of ATP. Knowledge of both the forward and reverse rates allows calculation of the free energy changes at each step and how it changes when coupled to an energy-requiring conformational step such as unwinding of an RNA helix. This chapter describes the principal types of oxygen isotopic exchange reactions that are applicable to ATPases, in general, and helicases, in particular, their application and their interpretation.

description: We perform three-dimensional (3D) compressible MHD simulations over many dynamical times for an extended range of sonic and Alfven Mach numbers and analyze the statistics of 3D density and 2D column density, which include probability distribution functions, spectra, skewness, kurtosis, She-Leveque exponents, and genus. In order to establish the relation between the statistics of the observables, i.e. column densities, and the underlying 3D statistics of density, we analyze the effects of cloud boundaries. We define the parameter space for 3D measures to be recovered from column densities. In addition, we show that for subsonic turbulence the spectra of density fluctuations are consistent with k^-7/3 in the case of a strong magnetic field and k^-5/3 in the case of a weak magnetic field. For supersonic turbulence we confirm the earlier findings of the shallow spectra of density and Kolmogorov spectra of the logarithm of density. We find that the intermittencies of the density and velocity are very different.

description: Abstract

This thesis investigates the potential contributions of Sharia Law to the evolving framework of international environmental governance. It moves beyond the notion ofa monolithic "Islamic environmental law" and instead examines how core Sharia principles and interpretations can inform and strengthen international environmental efforts. The analysis draws on key passages from the Quran and Sunnah, evaluating them through the lens of environmental stewardship and the concept of Maqasid al- Sharia (higher objectives of Islamic law). It explores the applicability of Islamic legal tools and reasoning to contemporary environmental challenges. Additionally, thethesis examines the potential of Sharia to bridge cultural divides and foster broader participation in international environmental governance.

description: Kepler allows the measurement of starspot variability in a large sample of field red giants for the first time. With a new method that combines autocorrelation and wavelet decomposition, we measure 361 rotation periods from the full set of 17,377 oscillating red giants in our sample. This represents 2.08% of the stars, consistent with the fraction of spectroscopically detected rapidly rotating giants in the field. The remaining stars do not show enough variability to allow us to measure a reliable surface rotation period. Because the stars with detected rotation periods have measured oscillations, we can infer their global properties, e.g. mass and radius, and quantitatively evaluate the predictions of standard stellar evolution models as a function of mass. Consistent with results for cluster giants when we consider only the 4881 intermediate-mass stars, M>2.0 M$_\odot$ from our full red giant sample, we do not find the enhanced rates of rapid rotation expected from angular momentum conservation. We therefore suggest that either enhanced angular momentum loss or radial differential rotation must be occurring in these stars. Finally, when we examine the 575 low-mass (M<1.1 M$_\odot$) red clump stars in our sample, which were expected to exhibit slow (non-detectable) rotation, 15% of them actually have detectable rotation. This suggests a high rate of interactions and stellar mergers on the red giant branch.

description: Physiological conditions that impinge on constitutive traffic and affect organelle structure are not known. We report that osmotically induced cell volume changes, which are known to occur under a variety of conditions, rapidly inhibited endoplasmic reticulum (ER)-to-Golgi transport in mammalian cells. Both ER export and ER Golgi intermediate compartment (ERGIC)-to-Golgi trafficking steps were blocked, but retrograde transport was active, and it mediated ERGIC and Golgi collapse into the ER. Extensive tubulation and relatively rapid Golgi resident redistribution were observed under hypo-osmotic conditions, whereas a slower redistribution of the same markers, without apparent tubulation, was observed under hyperosmotic conditions. The osmotic stress response correlated with the perturbation of COPI function, because both hypo- and hyperosmotic conditions slowed brefeldin A-induced dissociation of betaCOP from Golgi membranes. Remarkably, Golgi residents reemerged after several hours of sustained incubation in hypotonic or hypertonic medium. Reemergence was independent of new protein synthesis but required PKC, an activity known to mediate cell volume recovery. Taken together these results indicate the existence of a coupling between cell volume and constitutive traffic that impacts organelle structure through independent effects on anterograde and retrograde flow and that involves, in part, modulation of COPI function.

description: We calculate the production cross sections for $D^{*+}D^{*-}$, $D^+D^{*-}$ and $D^+D^-$ in $e^+e^-$ annihilation through one virtual photon in the framework of perturbative QCD with constituent quarks. The calculated cross sections for $D^{*+}D^{*-}$ and $D^+D^{*-}$ production are roughly in agreement with the recent Belle data. The helicity decomposition for $D^{*}$ meson production is also calculated. The fraction of the $D^{*\pm}_LD^{*\mp}_T$ final state in $e^+e^-\to D^{*+}D^{*-}$ process is found to be 65%. The fraction of $DD^*_T$ production is 100% and $DD^*_L$ is forbidden in $e^+e^-$ annihilation through one virtual photon. We further consider $e^+e^-$ annihilation through two virtual photons, and then find the fraction of $DD^{*}_T$ in $e^+e^-\to DD^{*}$ process to be about 91%.

description: It is known that soliton solutions of the KP-hierarchy corresponds to singular rational curves with only ordinary double points. In this paper we study the degeneration of theta function solutions corresponding to certain trigonal curves. We show that, when the curves degenerate to singular rational curves with only ordinary triple points, the solutions tend to some intermediate solutions between solitons and rational solutions. They are considered as cerain limits of solitons. The Sato Grassmannian is extensively used here to study the degeneration of solutions, since it directly connects solutions of the KP-hierarchy to the defining equations of algebraic curves.We define a class of solutions in the Wronskian form which contains soliton solutions as a subclass and prove that, using the Sato Grassmannian, the degenerate trigonal solutions are connected to those solutions by certain gauge transformations

description: Mitral/tufted (M/T) cells of the main olfactory bulb transmit odorant information to higher brain structures. The relative timing of action potentials across M/T cells has been proposed to encode this information and to be critical for the activation of downstream neurons. Using ensemble recordings from the mouse olfactory bulb in vivo, we measured how correlations between cells are shaped by stimulus (odor) identity, common respiratory drive, and other cells' activity. The shared respiration cycle is the largest source of correlated firing, but even after accounting for all observable factors a residual positive noise correlation was observed. Noise correlation was maximal on a ∼100-ms timescale and was seen only in cells separated by <200 >µm. This correlation is explained primarily by common activity in groups of nearby cells. Thus, M/T-cell correlation principally reflects respiratory modulation and sparse, local network connectivity, with odor identity accounting for a minor component.
title: Investigating the role of tumour derived hydrogen sulphide and its synthases in endometrial cancer tumourigenesis.

description: Endometrial cancer is the 4th most common gynaecological malignancy in developed countries with a continual rise in incidence of >40% reported between the years of 1993-2007. Though endometrial cancer presents early with abnormal uterine bleeding the therapeutic options are limited with surgery being the hallmark treatment for these women. Recent evidence published has implicated the new gaseous transmitter hydrogen sulphide (H2S) in the pathogenesis of colorectal carcinoma. The results of this study strongly suggested a role for H2S synthase inhibitors as a possible therapeutic option. No prior studies have been conducted exploring the role of H2S in relation to endometrial carcinogenesis. This study aims to produce novel research exploring the role of H2S in endometrial carcinogenesis. Immunohistochemical techniques were used to stain a total of 81 human endometrial samples (post-menopausal n=16, complex atypical hyperplasias n=4 and endometrial cancers n=61) with H2S synthases i.e. Cystathionine-β-synthase (CBS), Cystathionine gamma-lyase (CSE) and 3-mercaptopyruvate sulphurtransferase (3-MPST) to elucidate their differential expression between these groups. In vitro experiments were carried out investigating the effects of H2S donors i.e. GYY4137 and H2S substrates such as L-cysteine on the proliferative potential of the endometrial cancer cell known as MFE280. The results of this study concluded that the endometrium positively expresses all 3 enzymes. 3-MPST displayed higher levels of expression in the atrophic post-menopausal endometrium with a significant loss in its expression seen in low grade endometrial cancer cells (p<0.0001), suggesting a possible role for 3-MPST as an early disease marker. CSE like 3-MPST displayed a significant reduction in expression in cancerous cells when compared with post-menopausal and hyperplastic endometrium (p<0.001) whilst CBS showed no overall difference in expression between all study groups (p=0.136). Results of the in vitro investigations revealed an overall inhibition of cell viability of endometrial cancer cells when treated with a range of concentrations of H2S donors and substrates. Analysis of the above results presents a possible protective role of 3-MPST and CSE within the endometrium and their subsequent loss contributing to the development of endometrial carcinogenesis. Furthermore, the possibility of employing H2S donors as therapeutic agents in endometrial carcinomas may be a promising intervention and further functional studies will need to be conducted before conclusions regarding the latter can be determined.
