Functional diversity is a component of biodiversity that generally covers the range of functional traits of microorganisms prevailing in an ecosystem. Functional diversity is of high ecological importance because it is capable of influencing several aspects of ecosystem functioning like ecosystem dynamics, stability, nutrient availability, etc. Functional diversity of a community can be measured by functional richness and evenness. Functional richness refers to the number of species inhabiting a particular niche and functional evenness reveals how evenly the species are being distributed. Increase or decrease in functional richness and evenness simultaneously increases and decreases the functional diversity respectively. Decrease in functional richness and evenness decreases the ecosystem productivity and stability which ultimately decreases functional diversity of the same ecosystem. The effects of functional diversity on the productivity of an ecosystem can be quantitatively explained by the sampling effect model and the niche differentiation model. There are other proposed mechanisms like Niche complementarity and species redundancy relating functional diversity with ecosystem functioning. Rivets and idiosyncratic models relate functional diversity and species richness with ecosystem functioning. By considering the above proposed models on ecosystem functioning, it can be considered that functional diversity is a principal component of ecosystem functioning. So it can be assumed that, knowledge about a particular ecosystem reveals its richness and evenness which enable an individual knowing about the diversity of functional traits prevailing in the ecosystem. Thus, it opens up a new way in understanding and carrying out ecology related studies more efficiently and precisely in ecosystem.

Quality poultry meat depends upon the feed and as such there are many commercially available feeds. However, their composition and standard by and large throughout the year may not remain same due to obvious reasons. Moreover, there is no mention of locally produced feed particularly in the north eastern part of India. The major objective of this study was to prepare mesh feed E1 with the available ingredients as well as their effect were compared with that of the two commercially available feed Amrit and Godrej (E2 and E3) in terms of Crude protein, fats and element composition. The findings showed that the protein content (240 g/kg) and fats (105 g/kg) in the breast muscle of female was higher in the E3 received against the broiler chicken received local feed. Element analysis of the E1, E2 and E3 depicted significantly higher value of Ca, K, Cu Zn and Se against the commercial feed. Other elements like Mg, Na, Fe, P, and Mn showed no variation while compared E1, E2 and E3 together. Thus the present findings suggest that the local feed E1 could be accepted at per with that of the commercial feed for poultry.

BACKGROUND Optimizing patients with advanced heart failure before orthotopic heart transplantation(OHT), especially in patients greater than 50 years old, is imperative to achieving successful post-transplant outcomes. Complications are well-described for patients bridged to transplant(BTT) with durable left ventricular assist device(LVAD) support. Given the lack of data available in older recipients after the recent increase in mechanical support use, we felt it crucial to report our center’s one-year outcomes in older recipients after heart transplantation with percutaneously placed Impella 5.5 as a *** Forty-nine OHT patients were supported with the Impella 5.5 intended as a bridge between December 2019 and October 2022 at Mayo Clinic in Florida. Data were extracted from the electronic health record at baseline and during their transplant episode of care after Institutional Review Boards approval as exempt for retrospective data *** Thirty-eight patients aged 50 or older were supported with Impella 5.5 as BTT. Ten patients underwent heart and kidney transplantation within this cohort. The median age at OHT was 63(58–68) years, with 32 male(84%) and six female patients(16%). Etiology was divided into ischemic(63%) and non-ischemic cardiomyopathy(37%). The baseline median ejection fraction was 19%(15–24). Most patients were in blood group O(60%), and 50% were diabetic. The average duration of support was 27 days(range 6–94). The median duration of follow-up is 488 days(185–693). For patients that have reached the 1-year follow-up timeframe(22 of 38, 58%), the 1-year post-transplant survival is 95%.CONCLUSION Our single-center data provides awareness for using the Impella 5.5 percutaneously placed axillary support device in older heart failure patients in cardiogenic shock as a bridge to transplantation. One-year survival outcomes after heart transplantation are excellent despite the older recipient’s age and prolonged pre-transplant support.

Characterization of an aqueous extract of human placenta, used as a licensed drug for wound healing, leads to the identification of several bioactive components including polydeoxyribonu-cleotides (PDRNs). PDRNs are mixture of DNA fragments of different molecular weight. A spectro-fluorimetric method of quantitation of PDRNs in the aqueous extract of human placenta by using ethidium bromide (EtBr) has been described here. It has been demonstrated by thin layer chromatography (TLC) followed by reversed phase HPLC that EtBr binds specifically with the PDRN fraction of the multi-component extract. The binding specificity of EtBr has been verified by the analysis of emission spectra of the extract. A concentration of 0.29 μg/ml EtBr exhibits a linear range of standard CT-DNA from 0.5 - 5 μg/ml of buffer (R2 = 0.992). The same concentration of EtBr shows a linear range of measurements of placenta extract from 5 - 35 μl/ml of buffer (R2 = 0.976). The points of the curve were the average of three sets where maximum variation observed was ±3%. PDRN content of the extract has been estimated based on the resultant fluorescence emission (after background correction) with respect to the standard calibration curve of calf thymus DNA (CT-DNA). Estimation of PDRN in a large number of batches of placenta extract (n = 100) has been done. The statistical analysis of the estimation was found to be significant and the lower and upper levels of PDRN were 158.30 and 239.03 μg/ml of the extract respectively. This easy-to-use method of estimation of PDRN in multi-component biological extract is reported for the first time. This will help in quantitation of PDRNs for other biological extracts.

The reversible effect of microwave mediated denaturation of protein at low exposure time of 10 s has been demonstrated for the first time. The effect of microwave (2.45 GHz and 900 W) was confirmed in a homo-octameric alcohol oxidase in aqueous solution of pH 7.5. The unfolding events did not transverse through any intermediate states and no subunits of the protein were detached during the process. The refolding of the protein achieved at 4℃ for 24 h had regenerated the native enzyme. This reversible refolding approach excludes any chemical reagent and therefore established as simple technique for protein unfolding-folding studies.

A large volume of overburden and mine wastes is generated during the extraction and beneficiation of the low grade ores. The waste low grade manganiferous iron ore fine from southern part of India was studied for recovery of iron values. The chemical assay of the sample is 52.36% Fe, 4.75% Mn, 8.5% SiO2 and 2.82% Al2O3. The characterization study of the sample indicates the presence of microplaty hematite, goethite, pyrolusite, cryptomelane with minor amount of quartz and kaolinite. The beneficiation study of the sample does not respond to the conventional route of desliming the ground feed followed by gravity separation and magnetic separation. Therefore, an alternative technique of reduction roasting using a producer gas was attempted at different conditions. The characterization of roasted product reveals the phase transformation to magnetite and microplaty magnetite. The low intensity magnetic separation conducted with the roasted products generated at optimal condition shows that 70% concentrate having 64.5% Fe and 1.87% Mn could be produced. The high manganese in the concentrate works as an additive for making pellet with enhancement in pellet strength and drop in reducibility. Utilization of mines waste has significant impact on mineral resources and environmental hazard.

In this paper, Finite Difference Time Domain (FDTD) is utilized to simulate metamaterials of Double Negative (DNG) origin that refers to those materials having simultaneous negative permittivity and permeability. The problem regarding space formulation is achieved by means of auxiliary differential equation method (ADE), which is easy, reliable and also causal process in nature thus making it proficient. It uses fair approximations to explicate the model. Mur’s boundary condition is used for 1-D problem space and convolution perfectly matched layer boundary is implemented for 2-D problem space. The properties of metamaterial conform their speculations of energy absorption, enhancement and backward propagation property with the aid of graphs engineered by Matlab simulation both in 1-D and 2-D. Also, the interaction of fields on DNG and Double Positive (DPS) layers is contrasted. The results achieved elucidate the validity and effectiveness of the ADE method and the Convolution Perfectly Match Layer (CPML) in designing DNG metamaterials.
