Abstract: ABSTRACTOBJECTIVE: To assess and compare anti-inflammatory effect of pioglitazone and gemfibrozil by measuring C-reactive protein (CRP) levels in high fat fed non-diabetic rats.METHODS: A comparative animal study was conducted at the Post Graduate Medical Institute, Lahore, Pakistan in which 27, adult healthy male Sprague Dawley rats were used. The rats were divided into three groups. Hyperlipidemia was induced in all three groups by giving hyperlipidemic diet containing cholesterol 1.5%, coconut oil 8.0% and sodium cholate 1.0%. After four weeks, Group A (control) was given distilled water, Group B was given pioglitazone 10mg/kg body weight and Group C was given gemfibrozil 10mg/kg body weight as single morning dose by oral route for four weeks. CRP was estimated at zero, 4th and 8th week.RESULTS: There was significant increase in the level of CRP after giving high lipid diet from mean±SD of 2.59±0.28mg/L, 2.63±0.32mg/L and 2.67±0.23mg/L at 0 week to 3.55±0.44mg/L, 3.59±0.34mg/L and 3.6±0.32mg/L at 4th week in groups A, B and C respectively.Multiple comparisons by ANOVA revealed significant difference between groups at 8th week only. Post hoc analysis disclosed that CRP level was significantly low in pioglitazone treated group having mean±SD of 2.93±0.33mg/L compared to control group’s 4.42±0.30mg/L and gemfibrozil group’s 4.28±0.39mg/L. The p-value in each case was <0.001, while difference between control and gemfibrozil was not statistically significant.CONCLUSION: Pioglitazone is effective in reducing hyperlipidemia associated inflammation, evidenced by decreased CRP level while gemfibrozil is not effective.KEY WORDS: Pioglitazone (MeSH); Gemfibrozil (MeSH); Hyperlipidemia (MeSH); Anti-inflammatory (MeSH); C-reactive protein (MeSH).

Title: A soluble cryogenic thermometer with high sensitivity based on excited-state configuration transformations
Abstract: Cryogenic temperature detection plays an irreplaceable role in exploring nature. Developing high sensitivity, accurate, observable and convenient measurements of cryogenic temperature is not only a challenge but also an opportunity for the thermometer field. The small molecule 9-(9,9-dimethyl-9H-fluoren-3yl)-14-phenyl-9,14-dihydrodibenzo[a,c]phenazine (FIPAC) in 2-methyl-tetrahydrofuran (MeTHF) solution is utilized for the detection of cryogenic temperature with a wide range from 138 K to 343 K. This system possesses significantly high sensitivity at low temperature, which reaches as high as 19.4% K(-1) at 138 K. The temperature-dependent ratio of the dual emission intensity can be fitted as a single-exponential curve as a function of temperature. This single-exponential curve can be explained by the mechanism that the dual emission feature of FIPAC results from the excited-state configuration transformations upon heating or cooling, which is very different from the previously reported mechanisms. Here, our work gives an overall interpretation for this mechanism. Therefore, application of FIPAC as a cryogenic thermometer is experimentally and theoretically feasible.

Title: Continuous Symmetry Breaking Induced by Ion Pairing Effect in Heptamethine Cyanine Dyes: Beyond the Cyanine Limit
Abstract: The association of heptamethine cyanine cation 1(+) with various counterions A (A = Br(-), I(-), PF(6)(-), SbF(6)(-), B(C(6)F(5))(4)(-), TRISPHAT) was realized. The six different ion pairs have been characterized by X-ray diffraction, and their absorption properties were studied in polar (DCM) and apolar (toluene) solvents. A small, hard anion (Br(-)) is able to strongly polarize the polymethine chain, resulting in the stabilization of an asymmetric dipolar-like structure in the crystal and in nondissociating solvents. On the contrary, in more polar solvents or when it is associated with a bulky soft anion (TRISPHAT or B(C(6)F(5))(4)(-)), the same cyanine dye adopts preferentially the ideal polymethine state. The solid-state and solution absorption properties of heptamethine dyes are therefore strongly correlated to the nature of the counterion.

Title: The Third Place: The Library as Collaborative and Community Space in a Time of Fiscal Restraint
Abstract: In a period of fiscal constraint, when assumptions about the library as place are being challenged, administrators question the contribution of every expense to student success. Libraries have been successful in migrating resources and services to a digital environment accessible beyond the library. What is the role of the library as place when users do not need to visit the building to utilize library services and resources? We argue that the college library building's core role is as a space for collaborative learning and community interaction that cannot be jettisoned in the new normal.

Title: Identification, distribution and possible origins of sulfates in Capri Chasma (Mars), inferred from CRISM data
Abstract: CRISM is a hyperspectral imager onboard the Mars Reconnaissance Orbiter (MRO; NASA, 2005) which has been acquiring data since November 2006 and has targeted hydrated minerals previously detected by OMEGA (Mars Express; ESA, 2003). The present study focuses on hydrated minerals detected with CRISM at high spatial resolution in the vicinity of Capri Chasma, a canyon of the Valles Marineris system. CRISM data were processed and coupled with MRO and other spacecraft data, in particular HiRiSE (High Resolution Science Experiment, MRO) images. Detections revealed sulfates in abundance in Capri, especially linked to the interior layered deposits (ILD) that lie in the central part of the chasma. Both monohydrated and polyhydrated sulfates are found at different elevations and are associated with different layers. Monohydrated sulfates are widely detected over the massive light-toned cliffs of the ILD, whereas polyhydrated sulfates seem to form a basal and a top layer associated with lower-albedo deposits in flatter areas. Hydrated silicates (phyllosilicates or opaline silica) have also been detected very locally on two mounds about a few hundred meters in diameter at the bottom of the ILD cliffs. We suggest some formation models of these minerals that are consistent with our observations.

Title: Elorza Crater on Mars: identification of phyllosilicate-bearing minerals by MRO-CRISM
Abstract: The Elorza crater is located in the Ophir Planum region of Mars with a 40-km diameter, centered near 550.25’ W, 80.72’ S. Since the Elorza crater has clays rich deposits it was one of the important crater to understand the past aqueous alteration processes of planet Mars.

Title: Goldschmidt crater and the Moon's north polar region: Results from the Moon Mineralogy Mapper (M3)
Abstract: [1] Soils within the impact crater Goldschmidt have been identified as spectrally distinct from the local highland material. High spatial and spectral resolution data from the Moon Mineralogy Mapper (M3) on the Chandrayaan-1 orbiter are used to examine the character of Goldschmidt crater in detail. Spectral parameters applied to a north polar mosaic of M3 data are used to discern large-scale compositional trends at the northern high latitudes, and spectra from three widely separated regions are compared to spectra from Goldschmidt. The results highlight the compositional diversity of the lunar nearside, in particular, where feldspathic soils with a low-Ca pyroxene component are pervasive, but exclusively feldspathic regions and small areas of basaltic composition are also observed. Additionally, we find that the relative strengths of the diagnostic OH/H2O absorption feature near 3000 nm are correlated with the mineralogy of the host material. On both global and local scales, the strongest hydrous absorptions occur on the more feldspathic surfaces. Thus, M3 data suggest that while the feldspathic soils within Goldschmidt crater are enhanced in OH/H2O compared to the relatively mafic nearside polar highlands, their hydration signatures are similar to those observed in the feldspathic highlands on the farside.

Title: The distribution and purity of anorthosite across the Orientale basin: New perspectives from Moon Mineralogy Mapper data: CRYSTALLINE ANORTHOSITE ACROSS ORIENTALE
Abstract: The Orientale basin is a multiring impact structure on the western limb of the Moon that provides a clear view of the primary lunar crust exposed during basin formation. Previously, near‐infrared reflectance spectra suggested that Orientale's Inner Rook Ring (IRR) is very poor in mafic minerals and may represent anorthosite excavated from the Moon's upper crust. However, detailed assessment of the mineralogy of these anorthosites was prohibited because the available spectroscopic data sets did not identify the diagnostic plagioclase absorption feature near 1250 nm. Recently, however, this absorption has been identified in several spectroscopic data sets, including the Moon Mineralogy Mapper (M3), enabling the unique identification of a plagioclase‐dominated lithology at Orientale for the first time. Here we present the first in‐depth characterization of the Orientale anorthosites based on direct measurement of their plagioclase component. In addition, detailed geologic context of the exposures is discussed based on analysis of Lunar Reconnaissance Orbiter Narrow Angle Camera images for selected anorthosite identifications. The results confirm that anorthosite is overwhelmingly concentrated in the IRR. Comparison with nonlinear spectral mixing models suggests that the anorthosite is exceedingly pure, containing >95 vol % plagioclase in most areas and commonly ~99–100 vol %. These new data place important constraints on magma ocean crystallization scenarios, which must produce a zone of highly pure anorthosite spanning the entire lateral extent of the 430 km diameter IRR.

Title: Discoveries on the lithology of lunar crater central peaks by SELENE Spectral Profiler
Abstract: The Spectral Profiler (SP) onboard the Japanese SELENE (KAGUYA) spacecraft is now providing global high spectral resolution visible‐near infrared continuous reflectance spectra of the Moon. The reflectance spectra of impact craters on the farside of the Moon reveal lithologies that were not previously identified. The achievements of SP so far include: the most definite detection of crystalline iron‐bearing plagioclase with its characteristic 1.3 μm absorption band on the Moon; a new interpretation of the lithology of Tsiolkovsky crater central peaks, previously classified as “olivine‐rich,” as mixtures of plagioclase and pyroxene; and the lower limit of Mg number of low‐Ca pyroxene found at Antoniadi crater central peak and peak ring which were estimated through direct comparison with laboratory spectra of natural and synthetic pyroxene samples.

Title: Identification of Potential Mantle Rocks Around the Lunar Imbrium Basin
Abstract: Basin‐forming impacts expose material from deep within the interior of the Moon. Given the number of lunar basins, one would expect to find samples of the lunar mantle among those returned by the Apollo or Luna missions or within the lunar meteorite collection. However, only a few candidate mantle samples have been identified. Some remotely detected locations have been postulated to contain mantle‐derived material, but none are mineralogically consistent upon study with multiple techniques. To locate potential remnants of the lunar mantle, we searched for early‐crystallizing minerals using data from the Moon Mineralogy Mapper (M3) and the Diviner Lunar Radiometer (Diviner). While the lunar crust is largely composed of plagioclase, the mantle should contain almost none. M3 spectra were used to identify massifs bearing mafic minerals and Diviner was used to constrain the relative abundance of plagioclase. Of the sites analyzed, only Mons Wolff was found to potentially contain mantle material.

Title: Mineralogy of the MSL Curiosity landing site in Gale crater as observed by MRO/CRISM
Abstract: Orbital data acquired by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) and High Resolution Imaging Science Experiment instruments on the Mars Reconnaissance Orbiter (MRO) provide a synoptic view of compositional stratigraphy on the floor of Gale crater surrounding the area where the Mars Science Laboratory (MSL) Curiosity landed. Fractured, light‐toned material exhibits a 2.2 µm absorption consistent with enrichment in hydroxylated silica. This material may be distal sediment from the Peace Vallis fan, with cement and fracture fill containing the silica. This unit is overlain by more basaltic material, which has 1 µm and 2 µm absorptions due to pyroxene that are typical of Martian basaltic materials. Both materials are partially obscured by aeolian dust and basaltic sand. Dunes to the southeast exhibit differences in mafic mineral signatures, with barchan dunes enhanced in olivine relative to pyroxene‐containing longitudinal dunes. This compositional difference may be related to aeolian grain sorting.

Title: Martian minerals components at Gale crater detected by MRO CRISM hyperspectral images
Abstract: Gale Crater on Mars has the layered structure of deposit covered by the Noachian/Hesperian boundary. Mineral identification and classification at this region can provide important constrains on environment and geological evolution for Mars. Although Curiosity rove has provided the in-situ mineralogical analysis in Gale, but it restricted in small areas. Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard the Mars Reconnaissance Orbiter (MRO) with enhanced spectral resolution can provide more information in spatial and time scale. In this paper, CRISM near-infrared spectral data are used to identify mineral classes and groups at Martian Gale region. By using diagnostic absorptions features analysis in conjunction with spectral angle mapper (SAM), detailed mineral species are identified at Gale region, e.g., kaolinite, chlorites, smectite, jarosite, and northupite. The clay minerals' diversity in Gale Crater suggests the variation of aqueous alteration. The detection of northupite suggests that the Gale region has experienced the climate change from moist condition with mineral dissolution to dryer climate with water evaporation. The presence of ferric sulfate mineral jarosite formed through the oxidation of iron sulfides in acidic environments shows the experience of acidic sulfur-rich condition in Gale history.

Title: Geological characteristics of hydrated minerals on Mars from MRO CRISM images
Abstract: Identification of Martian surface minerals can contribute to understand the Martian environmental change and geological evolution as well as explore the habitability of the Mars. The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard the Mars Reconnaissance Orbiter (MRO) is covers the visible to near infrared wavelengths along with enhanced spectral resolution, which provides ability to map the mineralogy on Mars. In this paper, based on the spectrum matching, mineral composition and geological evolution of Martian Jezero and Holden crater are analyzed using the MRO CRISM. The hydrated minerals are detected in the studied areas, including the carbonate, hydrated silicate and hydrated sulfate. These minerals suggested that the Holden and Jezero craters have experienced long time water-rock interactions. Also, the diverse alteration minerals found in these regions indicate the aqueous activities in multiple distinct environments.

Title: Raman spectroscopy for mineral identification and quantification for in situ planetary surface analysis: A point count method
Abstract: Quantification of mineral proportions in rocks and soils by Raman spectroscopy on a planetary surface is best done by taking many narrow-beam spectra from different locations on the rock or soil, with each spectrum yielding peaks from only one or two minerals. The proportion of each mineral in the rock or soil can then be determined from the fraction of the spectra that contain its peaks, in analogy with the standard petrographic technique of point counting. The method can also be used for nondestructive laboratory characterization of rock samples. Although Raman peaks for different minerals seldom overlap each other, it is impractical to obtain proportions of constituent minerals by Raman spectroscopy through analysis of peak intensities in a spectrum obtained by broad-beam sensing of a representative area of the target material. That is because the Raman signal strength produced by a mineral in a rock or soil is not related in a simple way through the Raman scattering cross section of that mineral to its proportion in the rock, and the signal-to-noise ratio of a Raman spectrum is poor when a sample is stimulated by a low-power laser beam of broad diameter. Results obtained by the Raman point-count method are demonstrated for a lunar thin section (14161,7062) and a rock fragment (15273,7039). Major minerals (plagioclase and pyroxene), minor minerals (cristobalite and K-feldspar), and accessory minerals (whitlockite, apatite, and baddeleyite) were easily identified. Identification of the rock types, KREEP basalt or melt rock, from the 100-location spectra was straightforward.

Title: Silica polymorphs in lunar granite: Implications for granite petrogenesis on the Moon
Abstract: Abstract Granitic lunar samples largely consist of granophyric intergrowths of silica and K-feldspar. The identification of the silica polymorph present in the granophyre can clarify the petrogenesis of the lunar granites. The presence of tridymite or cristobalite would indicate rapid crystallization at high temperature. Quartz would indicate crystallization at low temperature or perhaps intrusive, slow crystallization, allowing for the orderly transformation from high-temperature silica polymorphs (tridymite or cristobalite). We identify the silica polymorphs present in four granitic lunar samples from the Apollo 12 regolith using laser Raman spectroscopy. Typically, lunar silica occurs with a hackle fracture pattern. We did an initial density calculation on the hackle fracture pattern of quartz and determined that the volume of quartz and fracture space is consistent with a molar volume contraction from tridymite or cristobalite, both of which are less dense than quartz. Moreover, we analyzed the silica in the granitic fragments from Apollo 12 by electron-probe microanalysis and found it contains up to 0.7 wt% TiO2, consistent with initial formation as the high-temperature silica polymorphs, which have more open crystal structures that can more readily accommodate cations other than Si. The silica in Apollo 12 granitic samples crystallized rapidly as tridymite or cristobalite, consistent with extrusive volcanism. The silica then inverted to quartz at a later time, causing it to contract and fracture. A hackle fracture pattern is common in silica occurring in extrusive lunar lithologies (e.g., mare basalt). The extrusive nature of these granitic samples makes them excellent candidates to be similar to the rocks that compose positive relief silicic features such as the Gruithuisen Domes.

Title: Phyllosilicate Diversity and Past Aqueous Activity Revealed at Mawrth Vallis, Mars
Abstract: Observations by the Mars Reconnaissance Orbiter/Compact Reconnaissance Imaging Spectrometer for Mars in the Mawrth Vallis region show several phyllosilicate species, indicating a wide range of past aqueous activity. Iron/magnesium (Fe/Mg)–smectite is observed in light-toned outcrops that probably formed via aqueous alteration of basalt of the ancient cratered terrain. This unit is overlain by rocks rich in hydrated silica, montmorillonite, and kaolinite that may have formed via subsequent leaching of Fe and Mg through extended aqueous events or a change in aqueous chemistry. A spectral feature attributed to an Fe2+ phase is present in many locations in the Mawrth Vallis region at the transition from Fe/Mg-smectite to aluminum/silicon (Al/Si)–rich units. Fe2+-bearing materials in terrestrial sediments are typically associated with microorganisms or changes in pH or cations and could be explained here by hydrothermal activity. The stratigraphy of Fe/Mg-smectite overlain by a ferrous phase, hydrated silica, and then Al-phyllosilicates implies a complex aqueous history.
