Role of curcumin as an antioxidant

In recent years, there is an upsurge in the areas related to newer developments in prevention of diseases, especially the role of free radicals and antioxidants; free radicals are unstable chemicals formed in the body during normal metabolism or exposure to environmental toxins such as pollutants in air, food, and water. Curcumin combined with enhancing agents provides multiple health benefits. Most of these benefits can be attributed to its antioxidant and anti-inflammatory effects. Ingesting curcumin by itself does not lead to the associated health benefits due to its poor bioavailability, which appears to be primarily due to poor absorption, rapid metabolism, and rapid elimination. There are several components that can increase bioavailability. The purpose of this review is to provide a brief overview of the plethora of research regarding the health benefits of curcumin.

African black velvet tamarind (Dialium guineense) as a green adsorbent for groundwater remediation

Process shells of black velvet tamarind fruits was investigated as an adsorbent for the potential removal of the pollutant heavy metal ions of Fe, Cr, Pb, Mn and Zn in well water samples collected from six different locations in Enugu Metropolis, Eastern Nigeria. Fourier Transform Infra-Red Spectroscopy absorption bands characteristic of stretching, scissoring and bending vibrations of - O-H groups of alcohols (R-OH) and phenols (Ph-OH), Sp3 (–C-H) of an oxygen bonded carbon atom, –C-O-C- bond and Sp2 (---C==C—H) carbons in a ring structure were seen between 3400 to 3200 cm-1, 1438 to 1371 cm-1, 2922/2851 cm-1 and 1155/1028 cm-1 as well as the 1509 cm-1 in the infra-red region of the electromagnetic spectrum in the infra-red absorption spectrum of processed black velvet tamarind fruit shells. Metal ion analysis was carried out by Flame Atomic Absorption Spectroscopy. The results showed that the adsorbent removed 40.50 to 63.30, 33.33 to 52.63, 26.23 to 48.05 and 15.00 to 37.84% respectively of Fe, Zn, Cr and Mn in the well water samples but was ineffective in removing Pb. This demonstrates the usefulness of black velvet tamarind fruit shells in decontaminating heavy metal burdened water and suggests that the technique has potential to reclaim polluted water of such nature, ameliorate the problems of insufficient potable water and waste disposal as well as protect the environment from heavy metal pollution.

Relationship between burnout and work engagement among Sri Lankan collegiate cycle students

Abstract Background Keeping on par with the emerging trend towards positive psychology focusing on optimal functioning, burnout research is also associated with a shift towards its positive antipode; work engagement. This study was aimed at determining the relationship between burnout and work engagement among collegiate cycle students in Sri Lanka. Methods A school-based, cross-sectional study was conducted among 872 grade thirteen students in 15 government schools in the Kegalle district, Sri Lanka. The validated Sinhala versions of the 15-item Maslach Burnout Inventory-Student Survey and the 16-item Utrecht Work Engagement Scale-Student Version were used to assess burnout and work engagement respectively. The relationship between subscales of burnout; viz., exhaustion (EX), cynicism (CY) and reduced professional efficacy (rPE); and subscales of work engagement; viz., vigor (VI), dedication (DE) and absorption (AB); were assessed using Pearson product-moment correlation coefficient. Results The response rate was 91.3%. The EX subscale of burnout had strong negative correlations with VI (r=-0.699) and AB (r=-0.642) subscales and a moderate negative correlation (r=-0.475) with DE subscale of work engagement. The CY subscale of burnout had a strong negative correlation with AB subscale (r=-0.577), a moderate negative correlation with VI subscale (r=-0.391) and a weak negative correlation (r=-0.195) with DE subscale. The rPE subscale of burnout had weak negative correlations with DE subscale (r=-0.218), AB subscale (r=-0.206) and VI subscale (r=-0.128). All these correlations between the subscales of burnout and work engagement were statistically significant (p < 0.001). Conclusions Given the significant negative correlation between burnout and work engagement, exploring student work engagement may allow identification of their positive psychological characteristics that can be incorporated in formulating packages for preventing burnout. Key messages Bivariate correlation revealed that all three subscales of burnout had statistically significant negative correlations with all three subscales of work engagement. Exploring student work engagement may allow identification of their positive psychological characteristics that can be incorporated in formulating packages for preventing burnout.

Porous carbon materials based on MOFs in microwave absorbing

With the rapid development of science and technology, especially the fast progress in the radar detection technology, lots of efforts have been made to obtain high performance microwave absorption materials. In recent years, carbon-based microwave absorption materials have received much attention because of their high-performance electromagnetic wave absorption performances, special microstructure and low density. However, they do not own an orderly structure, usually, and the impedance mismatching between carbon and air may hinder the incident electromagnetic waves enter into the microwave absorption materials and weaken its absorbing performance. Metal-organic frameworks (MOFs) has become a research hotspot almost in every filed of material chemistry due to its orderly structure, functional designability, etc. But the stability of MOFs is generally lower than the traditional porous materials. Under high temperature conditions, the structure may collapse in some extent. MOFs are often used as precursors to obtain target materials. After pyrolysis, porous carbon (NPC) and composite materials with relatively regular structure, a high specific surface area and a certain pore structure can be obtained, which is convenient for incorporating other materials with different loss mechanism in the NPC. At the same time, the carbonized NPC could be optimized to achieve good chemical stability, light weight, strong electromagnetic attenuation capability, and show excellent microwave absorption performance. In this paper, the properties of nanoporous carbon microwave absorption materials based on MOFs and their relationship between pore size and pore structure are discussed. Appropriate porosity provides a channel for EM waves to enter the microwave absorption materials, which helps to improve the impedance matching between electromagnetic waves and absorbers, thereby increasing the absorbing properties. The sizes and pore structures of the porous carbon microwave absorption materials also have an important effect on the interaction between the electromagnetic waves and the microwave absorption body. Three methods for synthesizing porous carbon of derived from MOFs are described, the advantages and disadvantages of these three methods are also analyzed. One is the one-step pyrolysis of MOFs for synthesis of porous carbons. The other is that the porous carbon obtained by pyrolysis of MOFs is recombined with different materials to carry on secondary calcination. The third method is introducing different nanoparticles into the micropores of MOFs before calcination, and then calcinating them together to prepare porous carbon composite microwave absorption materials. Previous studies show that the smaller the pore size, the more uniform the distribution, and the better the absorbing properties of the composite materials would be obtained. Porous carbon materials with different pore structures provide various propagation paths for electromagnetic waves to reflect and scatter in materials, resulting in different energy losses. The research status of microwave absorption of porous carbon materials based on magnetic metal MOFs, heteronuclear metal MOFs and non-magnetic metal MOFs are reviewed respectively. The microwave absorption mechanism of the porous carbon materials based on different metals MOFs examples or their influences on microwave absorption are also discussed. Porous carbon materials based on magnetic MOFs can improve the microwave absorbing properties by increasing the magnetic losses, and those based on heteronuclear MOFs combine the advantages of two or more materials, impart new chemical and physical properties to the materials and obtain high microwave absorption efficiency. The non-magnetic MOFs are carbonized to obtain non-magnetic metal oxide with low dielectric constant and their porous carbon composite materials, which could achieve excellent absorbing performance by improving impedance matching. Finally, the development trend of this kind of novel excellent absorption materials based on MOFs, with the advantages of strong loss, broad frequency bandwidth, thin thickness and lightweight, in the direction of diversification, compounding, lightweight and industrialization are prospected.

The Hubble PanCET program: an extensive search for metallic ions in the exosphere of GJ 436 b

Context. The quiet M2.5 star GJ 436 hosts a warm Neptune that displays an extended atmosphere that dwarfs its own host star. Predictions of atmospheric escape in such planets state that H atoms escape from the upper atmosphere in a collisional regime and that the flow can drag heavier atoms to the upper atmosphere. It is unclear, however, what astrophysical mechanisms drive the process. Aims. Our objective is to leverage the extensive coverage of observations of the far-ultraviolet (FUV) spectrum of GJ 436 obtained with the Cosmic Origins Spectrograph (COS) to search for signals of metallic ions in the upper atmosphere of GJ 436 b, as well as study the activity-induced variability of the star. Methods. We analyzed flux time-series of species present in the FUV spectrum of GJ 436 and successfully performed geocoronal contamination removal in the COS Lyman-α profiles obtained near the Earth’s night-side. Results. GJ 436 displays flaring events with a rate of ~10 d−1. There is evidence for a possibly long-lived active region or longitude that modulates the FUV metallic lines of the star with amplitudes up to 20%. Despite the strong geocoronal contamination in the COS spectra, we detected in-transit excess absorption signals of ~50 and ~30% in the blue and red wings, respectively, of the Lyman-α line. We rule out a wide range of excess absorption levels in the metallic lines of the star during transit. Conclusions. The large atmospheric loss of GJ 436 b observed in Lyman-α transmission spectra is stable over the timescale of a few years, and the red wing signal supports the presence of a variable hydrogen absorption source besides the stable exosphere. The previously claimed in-transit absorption in the Si III line is likely an artifact resulting from the stellar magnetic cycle. The non-detection of metallic ions in absorption could indicate that the escape is not hydrodynamic or that the atmospheric mixing is not efficient in dragging metals high enough for sublimation to produce a detectable escape rate of ions to the exosphere.

Novel models to assess drug absorption from lipid-based formulations

Drug candidates with low aqueous solubility and low permeability are increasingly common in modern drug discovery programs. These properties, however, are problematic for the oral administration of these drugs as the intestinal absorption and uptake in blood will be hampered. Dissolving these drugs in lipid-based formulations (LBFs) can overcome the solubility barrier and polymers may be added to increase drug absorption. Little is known about the driving forces of absorption from these LBFs in the presence of polymers. This thesis describes the development of in vitro, in vivo, and computational models to understand this process.

Effect of body size on the energetic physiology of the West Indian top shell Cittarium pica (Linnaeus, 1758)

Cittarium pica is an endangered Caribbean gastropod of ecological and economic importance. In order to provide the basis for the aquaculture development and/or population management of this species, the relationships among its body size and physiological variables associated with the energetic balance were assessed. Individual measurements of rates of egestion (ER), ingestion (IR), absorption (AR), oxygen consumption (OCR), ammonia excretion (UR), mucus production (MR), absorption efficiency (AE) and scope for growth (SFG), were carried out on specimens between 0.01 and 12.07 g of dry weight of the soft parts (DW) under controlled laboratory conditions. Most of the variables showed positive potential relationships with the DW of the animals (ER mg h -1 = 1.51 DW 0.37 , IR mg h -1 = 4.13 DW 0.32 , AR = 2.56 DW 0.30 , OCR mL O 2 h -1 = 0.38 DW 0.74 , UR μg NH 4 -N h -1 = 19.17 DW 0.78 , MR mg h -1 = 1.28 DW 0.14 and SFG = 36.92 DW 0.22 ). AE did not show any relationship with this variable. The large snails had faster input and output of energy compared to the small specimens, also having proportionally greater energetic expenditures, mucus production, and energetic balance.
