Milk-derived bioactive peptides have been identified as potential ingredients of health-promoting functional foods. These bioactive peptides are targeted at diet-related chronic diseases especially ...the non-communicable diseases viz., obesity, cardiovascular diseases and diabetes. Peptides derived from the milk of cow, goat, sheep, buffalo and camel exert multifunctional properties, including anti-microbial, immune modulatory, anti-oxidant, inhibitory effect on enzymes, anti-thrombotic, and antagonistic activities against various toxic agents. Majority of those regulate immunological, gastrointestinal, hormonal and neurological responses, thereby playing a vital role in the prevention of cancer, osteoporosis, hypertension and other disorders as discussed in this review. For the commercial production of such novel bioactive peptides large scale technologies based on membrane separation and ion exchange chromatography methods have been developed. Separation and identification of those peptides and their pharmacodynamic parameters are necessary to transfer their potent functional properties into food applications. The present review summarizes the preliminary classes of bioactive milk-derived peptides along with their physiological functions, general characteristics and potential applications in health-care.
The numerical kernel approach to difference imaging has been implemented and applied to gravitational microlensing events observed by the PLANET collaboration. The effect of an error in the ...source-star coordinates is explored and a new algorithm is presented for determining the precise coordinates of the microlens in blended events, essential for accurate photometry of difference images. It is shown how the photometric reference flux need not be measured directly from the reference image but can be obtained from measurements of the difference images combined with the knowledge of the statistical flux uncertainties. The improved performance of the new algorithm, relative to isis2, is demonstrated.
•CH4 emission was increased by 26% in rice-fish than rice alone.•N2O emission was decreased by 9% in rice-fish with common carp than rice alone.•The GWP and CEE increased by 29.5% in rice-fish with ...common carp than rice alone.•Rice+common carp in rainfed shallow lowland is economic, higher C credit compliance.•Indian major carps (mrigal rohu and catla) emit less GHGs than common carp.
Four fish species namely, Cirrhinus mrigala H. (mrigal), Labeo rohita H. (rohu), Cyprinus carpio L. (common carp) and Catla catla H. (catla) were introduced along with rice (Oryza sativa L.) cv. Varshadhan, in a rainfed shallow (0–25cm water depth) Inceptisol to evaluate the effect of fish species on methane (CH4) and nitrous oxide (N2O) emission in a rice-fish farming system. On seasonal basis, the emission of CH4 was significantly higher by 26% under rice-fish co-culture compared to rice alone. The maximum emission of CH4 (36% higher) was found under rice+common carp farming. On contrary, the emission of N2O was significantly lower by 9% under rice-fish compared to rice alone. Although the global warming potential (GWP) was highest (29.5% more) in rice+common carp, the CH4 and N2O emission from this treatment per unit of total yield (rice+fish) were at par and significantly lower, respectively, compared to rice alone. Further, it provided significantly higher yield (rice+fish) and economic benefit over rice and other rice+fish species combinations. The integration of common carp with rice in rainfed shallow lowland ecology is thus, one of the viable options for livelihood of the small and marginal farmers besides, higher carbon (C) credit compliance. However, Indian major carps, mrigal rohu and catla in order, are potentially less harmful in terms of GHGs emission in shallow rice fields besides, higher profitability and carbon credit compliance compared to rice farming alone.
•KBiFe2O5 (KBFO) is prepared via a solid-state reaction route and crystallizes in the monoclinic phase (P2/c).•The observed magnetodielectric (MD) coupling suggests that Inverse Dzyaloshinskii-Moriya ...interaction could be the origin.•The maximum MD and magnetoimpedance (MI) couplings measured at room temperature are −0.6% and 0.7%, respectively.•The capacitive MI effect suggests that the observed MD in KBFO is intrinsic.
In this work, polycrystalline KBiFe2O5 (KBFO), belonging to the brownmillerite class of monoclinic structure with space group P2/c, is synthesized using a solid-state reaction route. Magnetodielectric (MD) and magnetoimpedance (MI) characteristics of KBFO are studied over a wide temperature (10–300 K), magnetic field (0–1.3 T), and frequency (100 Hz to 1 MHz) range. Zero-field-cool (ZFC) and field-cool (FC) magnetization data show a bifurcation around 11 K, indicating blocking temperature (TB). At room temperature, MD and MI data as a function of the magnetic field shows maximum MD and MI coupling to be ∼−0.6% and ∼0.7%, respectively, at 50 kHz. With the decrease in temperature from 300 K to 50 K, magnetodielectric strength decreases (−0.6% to −0.06%), whereas magnetization increases from canted-antiferromagnetic (MS ≈ 0.16 emu g−1) to a weak ferromagnetic state (MS ≈ 0.44 emu g−1). It indicates the existence of Inverse Dzyaloshinskii-Moriya interaction causing MD coupling in KBFO. MD behavior is also reflected in magnetic field-dependent dielectric relaxation phenomena demonstrated through magnetic field-dependent activation energies. The difference in activation energies of magnetic field-dependent conduction mechanism (Eg ≈ 0.370 ± 0.018 eV) and MD loss relaxation (Eg ≈ 0.183 ± 0.006 eV) indicate both have a different origin. The presence of the capacitive MI effect demonstrates that the observed magnetodielectric coupling is intrinsic. The existence of both temperatures-dependent MD and MI coupling in KBFO makes it suitable for dynamic random access memory as well as novel magnetic sensors.

In this work, the EuxM1-xMgAl10O17M = Ba, Ca. Sr, Zn, and x = 0.05) phosphors were prepared through a combustion route technique. The complexing reagents namely urea (fuels) were used to synthesis ...for EuxBa1-xMgAl10O17 (BAM: Eu), EuxCa1-xMgAl10O17 (CAM: Eu), EuxSr1-xMgAl10O17 (SAM:Eu), and EuxZn1-xMgAl10O17 (ZAM:Eu) phosphors. The crystallinity of the synthesized compound, elemental analysis and surface morphology were measured using the PXRD FE-SEM, and FTIR spectroscopy respectability. The average crystallite size () of BAM: Eu, CAM:Eu, SAM: Eu, and ZAM: Eu were found 80, 30, 29, and 26 nm respectively. The photoluminescence emission spectra of phosphor were found broadband by the monitoring using common excitation (350 nm) and emission (450 nm). The CIE-1931 color- coordinates were calculated for each sample in the blue region. The overall PL emission was found near the blue BAM: Eu, SAM: Eu, and ZAM: Eu and blue-red CAM:Eu regions with high quantum efficiency and high color purity. Long-lasting PL decay was also recorded of samples with respect to all samples BAM:Eu was calculated from 0.46 to more than 40 min. Therefore, the BAM: Eu and other synthesized phosphors would be used as a blue-emitting phosphor in widely varying fields of lightings.
Rice bean (Vigna umbellata), an underrated legume, adapts to diverse climatic conditions with the potential to support food and nutritional security worldwide. It is used as a vegetable, minor food ...crop and a fodder crop, being a rich source of proteins, minerals, and essential fatty acids. However, little effort has been made to decipher the genetic and molecular basis of various useful traits in this crop. Therefore, we considered three economically important traits i.e., flowering, maturity and seed weight of rice bean and identified the associated candidate genes employing an associative transcriptomics approach on 100 diverse genotypes out of 1800 evaluated rice bean accessions from the Indian National Genebank.
The transcriptomics-based genotyping of one-hundred diverse rice bean cultivars followed by pre-processing of genotypic data resulted in 49,271 filtered markers. The STRUCTURE, PCA and Neighbor-Joining clustering of 100 genotypes revealed three putative sub-populations. The marker-trait association analysis involving various genome-wide association study (GWAS) models revealed significant association of 82 markers on 48 transcripts for flowering, 26 markers on 22 transcripts for maturity and 22 markers on 21 transcripts for seed weight. The transcript annotation provided information on the putative candidate genes for the considered traits. The candidate genes identified for flowering include HSC80, P-II PsbX, phospholipid-transporting-ATPase-9, pectin-acetylesterase-8 and E3-ubiquitin-protein-ligase-RHG1A. Further, the WRKY1 and DEAD-box-RH27 were found to be associated with seed weight. Furthermore, the associations of PIF3 and pentatricopeptide-repeat-containing-gene with maturity and seed weight, and aldo-keto-reductase with flowering and maturity were revealed.
This study offers insights into the genetic basis of key agronomic traits in rice bean, including flowering, maturity, and seed weight. The identified markers and associated candidate genes provide valuable resources for future exploration and targeted breeding, aiming to enhance the agronomic performance of rice bean cultivars. Notably, this research represents the first transcriptome-wide association study in pulse crop, uncovering the candidate genes for agronomically useful traits.
