Effects of microplastics, pesticides and nano-materials on fish health, oxidative stress and antioxidant defense mechanism
Microplastics and pesticides are emerging contaminants in the marine biota, which cause many harmful effects on aquatic organisms, especially on fish. Fish is a staple and affordable food source, rich in animal protein, along with various vitamins, essential amino acids, and minerals. Exposure of fish to microplastics, pesticides, and various nanoparticles generates ROS and induces oxidative stress, inflammation, immunotoxicity, genotoxicity, and DNA damage and alters gut microbiota, thus reducing the growth and quality of fish. Changes in fish behavioral patterns, swimming, and feeding habits were also observed under exposures to the above contaminants. These contaminants also affect the Nrf-2, JNK, ERK, NF-ĪŗB, and MAPK signaling pathways. And Nrf2-KEAP1 signalling modulates redox status marinating enzymes in fish. Effects of pesticides, microplastics, and nanoparticles found to modulate many antioxidant enzymes, including superoxide dismutase, catalase, and glutathione system. So, to protect fish health from stress, the contribution of nano-technology or nano-formulations was researched. A decrease in fish nutritional quality and population significantly impacts on the human diet, influencing traditions and economics worldwide. On the other hand, traces of microplastics and pesticides in the habitat water can enter humans by consuming contaminated fish which may result in serious health hazards. This review summarizes the oxidative stress caused due to microplastics, pesticides and nano-particle contamination or exposure in fish habitat water and their impact on human health. As a rescue mechanism, the use of nano-technology in the management of fish health and disease was discussed
2āChloropropionamide As a Low-Reactivity Electrophile for Irreversible Small-Molecule Probe Identification
Resurgent interest
in covalent target engagement in drug discovery
has demonstrated that small molecules containing weakly reactive electrophiles
can be safe and effective therapies. Several recently FDA-approved
drugs feature an acrylamide functionality to selectively engage cysteine
side chains of kinases (Ibrutinib, Afatinib, and Neratinib). Additional
electrophilic functionalities whose reactivity is compatible with
highly selective target engagement and <i>in vivo</i> application
could open new avenues in covalent small molecule discovery. Here,
we report the synthesis and evaluation of a library of small molecules
containing the 2-chloropropionamide functionality, which we demonstrate
is less reactive than typical acrylamide electrophiles. Although many
library members do not appear to label proteins in cells, we identified <i>S</i>-CW3554 as selectively labeling protein disulfide isomerase
and inhibiting its enzymatic activity. Subsequent profiling of the
library against five diverse cancer cell lines showed unique cytotoxicity
for <i>S</i>-CW3554 in cells derived from multiple myeloma,
a cancer recently reported to be sensitive to PDI inhibition. Our
novel PDI inhibitor highlights the potential of 2-chloropropionamides
as weak and stereochemically tunable electrophiles for covalent drug
discovery
Selection and validation of reliable reference genes for quantitative real-time PCR in Barnyard millet (Echinochloa spp.) under varied abiotic stress conditions
Abstract Quantitative real-time polymerase chain reaction (RT-qPCR) using a stable reference gene is widely used for gene expression research. Barnyard millet (Echinochloa spp.) is an ancient crop in Asia and Africa that is widely cultivated for food and fodder. It thrives well under drought, salinity, cold, and heat environmental conditions, besides adapting to any soil type. To date, there are no gene expression studies performed to identify the potential candidate gene responsible for stress response in barnyard millet, due to lack of reference gene. Here, 10 candidate reference genes, Actin (ACT), Ī±-tubulin (Ī±-TUB), Ī²-tubulin (Ī²-TUB), RNA pol II (RP II), elongation factor-1 alpha (EF-1Ī±), adenine phosphoribosyltransferase (APRT), TATA-binding protein-like factor (TLF), ubiquitin-conjugating enzyme 2 (UBC2), ubiquitin-conjugating enzyme E2L5 (UBC5) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH), were selected from mRNA sequences of E. crus-galli and E. colona var frumentacea. Five statistical algorithms (geNorm, NormFinder, BestKeeper, ĪCt, and RefFinder) were applied to determine the expression stabilities of these genes in barnyard millet grown under four different abiotic stress (drought, salinity, cold and heat) exposed at different time points. The UBC5 and É-TUB in drought, GAPDH in salinity, GAPDH and APRT in cold, and EF-1Ī± and RP II in heat were the most stable reference genes, whereas Ć-TUB was the least stable irrespective of stress conditions applied. Further Vn/Vnā+ā1 analysis revealed two reference genes were sufficient to normalize gene expression across all sample sets. The suitability of identified reference genes was validated with Cu-ZnSOD (SOD1) in the plants exposed to different abiotic stress conditions. The results revealed that the relative quantification of the SOD1 gene varied according to reference genes and the number of reference genes used, thus highlighting the importance of the choice of a reference gene in such experiments. This study provides a foundational framework for standardizing RT-qPCR analyses, enabling accurate gene expression profiling in barnyard millet

Razvoj i ispitivanje kontinuiranog tipa separatora semena mahunarki
A continuous type tamarind deseeder with a capacity of 75 kgā¢h-1 has been fabricated and evaluated at the Department of Agricultural Process Engineering, Tamil Nadu Agricultural University, Coimbatore, India. The machine consists of a seed separation unit and separate outlets for the seeds and deseeded fruits. In the seed separation unit, the fruits were subjected to impact and simultaneous shearing force by pegs mounted on the wooden roller to break open the fruit and to push the seeds out of the oblong sieve. After deseeding, the seeds and fruit pulp were collected separately through their respective outlets. The performance of the developed machine was evaluated based on deseeding efficiency. Evaluation was done by conducting experiments at different operating conditions including different moisture content of tamarind fruit (20.0, 22.5 and 25.0% on dry basis) and varying wooden roller speed (2.5, 3.4 and 4.2 mā¢s-1), feed rate (45, 60 and 75 kgā¢h-1) and horizontal clearance (14, 16 and 18 mm). The test results of the machine showed that a maximum deseeding efficiency of 89.15% was found at 22.5 percent moisture content on dry basis, with the wooden roller speed of 3.4 mā¢s-1, feed rate of 45 kgā¢h-1 and 16 mm horizontal clearance. As compared to existing manual methods of deseeding, the continuous type tamarind deseeder unit recorded 93.34 % saving in time and 74.9 % saving in operation cost.Kontinuirani tip separatora semena iz mahuna kapaciteta 75 kgā¢h-1 konstruisan je i ispitivan u Institutu za inženjering prehrambenih i poljoprivrednih procesa Poljoprivrednog univerziteta Tamil Nadu, Coimbatore, India.

Rezultati ogleda su pokazali da je maÅ”ina postigla maksimalnu efikasnost separacije od 89.15% pri: vlažnosti od 22.5%, brzini valjka od 3.4 mā¢s-1, protoku mase od 45 kgā¢h-1 i zazoru od 16 mm. U poreÄenju sa postojeÄim ruÄnim postupcima separacije, kontinuirani tip separatora postigao je skraÄenje radnog vremena od 93.34% i smanjenje troÅ”kova rada od 74.9%
Arylboronate Ester Based Diazeniumdiolates (BORO/NO), a Class of Hydrogen Peroxide Inducible Nitric Oxide (NO) Donors
Here,
we report the design, synthesis, and evaluation of arylboronate
ester based diazeniumdiolates (BORO/NO), a class of nitric oxide (NO)
donors activated by hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>),
a reactive oxygen species (ROS), to generate NO. We provide evidence
for the NO donorsā ability to permeate bacteria to produce
NO when exposed to H<sub>2</sub>O<sub>2</sub> supporting possible
applications for BORO/NO to study molecular mechanisms of NO generation
in response to elevated ROS
Substituent Effects on Reactive Oxygen Species (ROS) Generation by Hydroquinones
In
order to understand the structural aspects of stabilization
of hydroquinones and their ability to generate reactive oxygen species
(ROS), we designed and synthesized a series of 6-aryl-2,3-dihydro-1,4-benzoquinones.
These compounds equilibrate with the corresponding 6-aryl-1,4-dihydroxybenzenes
in an organic medium; a linear free energy relationship analysis gave
Ļ = +2.37, suggesting that this equilibrium was sensitive to
electronic effects. The propensity of the compound to enolize appears
to determine ROS-generating capability, thus offering scope for tunable
ROS generation
Characterization of Atypical Protein Tyrosine Kinase (PTK) Genes and Their Role in Abiotic Stress Response in Rice
Tyrosine phosphorylation constitutes up to 5% of the total phophoproteome. However, only limited studies are available on protein tyrosine kinases (PTKs) that catalyze protein tyrosine phosphorylation in plants. In this study, domain analysis of the 27 annotated PTK genes in rice genome led to the identification of 18 PTKs with tyrosine kinase domain. The kinase domain of rice PTKs shared high homology with that of dual specificity kinase BRASSINOSTEROID-INSENSITIVE 1 (BRI1) of Arabidopsis. In phylogenetic analysis, rice PTKs clustered with receptor-like cytoplasmic kinases-VII (RLCKs-VII) of Arabidopsis. mRNAseq analysis using Genevestigator revealed that rice PTKs except PTK9 and PTK16 express at moderate to high level in most tissues. PTK16 expression was highly abundant in panicle at flowering stage. mRNAseq data analysis led to the identification of drought, heat, salt, and submergence stress regulated PTK genes in rice. PTK14 was upregulated under all stresses. qRT-PCR analysis also showed that all PTKs except PTK10 were significantly upregulated in root under osmotic stress. Tissue specificity and abiotic stress mediated differential regulation of PTKs suggest their potential role in development and stress response of rice. The candidate dual specificity PTKs identified in this study paves way for molecular analysis of tyrosine phosphorylation in rice
