Regge Trajectories of Tetraquarks and Pentaquarks with Massive Quarks in the Flux Tube Model
In recent years, many tetraquarks and pentaquarks have been discovered by
various experimental groups and X(3872), Zc(3900), X(4430), P + c (4312), P + c
(4457) are some of the interesting observed tetraquark and pentaquark states.
The Regge trajectories of some such states are studied in view of the flux tube
model of hadrons with finite quark masses. The effect of flux tube (or string)
length variation on the Regge trajectories of these sates is analysed in
detail. It is observed that for a fixed angular momentum, the string length has
a constant value. Some other states are also proposed and the results obtained
are then compared with the studies by others. Our findings correspond rather
well with those of other researchers and with those of the experiment.Comment: 10 pages, 4 figures, Published in IJMP
BUCCAL MUCOADHESIVE FILMS
The buccal route of administration has many advantages, including gastrointestinal bypass surgery and first pass through the liver. The mucoadhesive membrane is a retention dosage form that can release the drug directly into the biological matrix. Cheek technology has proven to be an advanced alternative to other traditional devices. The type of drug delivery system. This is a mature technology for systemic administration of active pharmaceutical ingredients [API]. In addition, due to their small size and thinness, these films improve patient compliance. Over the past decade, because it is a promising delivery alternative for multiple therapeutic categories, including peptides, vaccines and nanoparticles. Mucosal adhesions are currently explained by six theories: electronics, adsorption, wettability, diffusion, degradation and mechanics. Various in vitro and in vivo techniques are suggested. Study its mechanism. This study includes an overview of the mechanisms and theories of mucosal adhesion, and introduces the most commonly used methods. The "film casting method" involves casting an aqueous solution and/or organic solvent to produce a film suitable for the application route. The determination of key properties such as mucosal adhesion strength, uniformity of active ingredient content and permeability are important research areas in the field of buccal membrane design
Marine fish landings in Andhra Pradesh during 2016 - An overview
Andhra Pradesh with a coastline of 974 km, and
nine coastal districts has 1.63 lakh marine fishermen
families residing in the 555 marine fishing villages
(Marine Fisheries Census 2010) who depend on
fishing either directly or through allied activities
for their livelihood. The state is cyclone prone and
during the past decade, cyclones have severely
affected the state’s fisheries sector. The marine fish
landings was 1.92 lakh tonnes (t) in the year 2016,
which was 35% less than that of the previous year.
The drastic reduction in the landings of the state
may be attributed to reduction in fishing operations
during the months of September, October and
November due to cyclone warnings. Among the
coastal districts, East Godavari contributed the
highest (33%) to total marine fish landings of the
state, followed by Visakhapatnam (22%) and
Srikakulam (11%). In spite of decline in the catch
contributions from a few landing centres like

A putative heat-responsive transcription factor (TaHD97) and its targets in wheat (Triticum aestivum) providing thermotolerance
214-223Transcription factors (TFs) are protein, which perform their role at transcriptional level by affecting the expression of various genes associated with metabolic pathways, growth and stress-associated genes (SAGs) at different developmental stages. Here, we identified 38 novel heat-responsive transcription factor genes from wheat cv. HD2985 by mining the de novo transcriptome data derived from heat shock (HS) treated wheat. Based on digital gene expression (DGE), a putative transcript (TaHD97) of ~1.1 kbas amplified and cloned from wheat cv. HD2985. The presence of heat stress transcription factor (HSF) DNA binding domain was observed in the amino acid sequence. Differential expression of TaHD97 was observed in HD2985 (thermotolerant) and HD2329 (thermosensitive) under heat stress. Tissue specific expression analysis showed up-regulation of TaHD97 in leaves, stem and endospermic tissues and down-regulation in root under HS. A positive correlation was established between the expression of TaHD97 and its target gene (HSP17 and HSP90) in wheat under heat stress. HSP17 transcripts were observed more in leaves of HD2985, as compared to HD2329. Thermotolerance related biochemical enzymes (SOD, CAT, GPX and TBARS) were observed higher in wheat cv. HD2985 showing maximum expression of TaHD97 under heat stress. There is a need for the functional validation of the gene TaHD97 in order to use it for the regulation of sHSP (catalytic chaperone) - a novel approach towards augmenting thermotolerance in wheat under heat stress
Population distribution analyses reveal a hierarchy of molecular players underlying parallel endocytic pathways.
Single-cell-resolved measurements reveal heterogeneous distributions of clathrin-dependent (CD) and -independent (CLIC/GEEC: CG) endocytic activity in Drosophila cell populations. dsRNA-mediated knockdown of core versus peripheral endocytic machinery induces strong changes in the mean, or subtle changes in the shapes of these distributions, respectively. By quantifying these subtle shape changes for 27 single-cell features which report on endocytic activity and cell morphology, we organize 1072 Drosophila genes into a tree-like hierarchy. We find that tree nodes contain gene sets enriched in functional classes and protein complexes, providing a portrait of core and peripheral control of CD and CG endocytosis. For 470 genes we obtain additional features from separate assays and classify them into early- or late-acting genes of the endocytic pathways. Detailed analyses of specific genes at intermediate levels of the tree suggest that Vacuolar ATPase and lysosomal genes involved in vacuolar biogenesis play an evolutionarily conserved role in CG endocytosis

Productivity and profitability of drip fertigated wheat (Triticum aestivum) – mungbean (Vigna radiata) – maize (Zea mays) cropping system
An experiment was conducted at the research farm of ICAR-Indian Agricultural Research Institute, New Delhi
during 2019–20 and 2020–21 to study the productivity and economic viability of wheat (Triticum aestivum L.)–
mungbean (Vigna radiata (L.) R. Wilczek)–maize (Zea mays L.) fertigated with 0, 60, 80, 100% recommended doses
of NPK and irrigated at 0.6 and 0.8 crop evapotranspiration (ETc) through subsurface (SSDI) and surface drip irrigation (SDI). The results were compared with the conventional practice of surface irrigation and soil application of 100% recommended doses of NPK. Grain yields of wheat, mungbean, maize and system wheat equivalent yield (SWEY) improved by 22.9, 7.2, 21.9 and 19.4%, respectively with increase in NPK fertigation doses from 60 to 100% and by 15.6, 9.2, 4.9 and 9.7% with the increase in irrigation frequency from 0.6 to 0.8 ETc. However, SDI and SSDI had equal system productivity (12.48 and 12.85 Mg/ha). The SWEY at 0.8ETc fertigated either with NPK80 or NPK100
was statistically at par (14.2–15.9 Mg/ha) with the conventional practice (14.3–15.2 Mg/ha). The cash inflow, net
income and benefit cost ratio (BCR) of the cropping system also increased successively with increase in fertigation
doses and irrigation frequency. The net income and BCR followed the order maize>wheat>mungbean. The net income under SSDI at 0.8 ETc with NPK80 or NPK100 in wheat, mungbean, maize and system was 11–13, 88–105, 1-9 and 8–14% higher than the conventional practice. At 0.8 ETc and NPK100, BCR in SSDI (1.86) was higher than in SDI
(1.71) and conventional system (1.67).
New quasar proximity zone size measurements at using the enlarged XQR-30 sample
Proximity zones of high-redshift quasars are unique probes of their central
supermassive black holes as well as the intergalactic medium in the last stages
of reionization. We present 22 new measurements of proximity zones of quasars
with redshifts between 5.8 and 6.6, using the enlarged XQR-30 sample of
high-resolution, high-SNR quasar spectra. The quasars in our sample have UV
magnitudes of and black hole masses of
\unicode{x2013} M. Our inferred proximity zone sizes
are 2\unicode{x2013}7 physical Mpc, with a typical uncertainty of less than
0.5 physical Mpc, which, for the first time, also includes uncertainty in the
quasar continuum. We find that the correlation between proximity zone sizes and
the quasar redshift, luminosity, or black hole mass, indicates a large
diversity of quasar lifetimes. Two of our proximity zone sizes are
exceptionally small. The spectrum of one of these quasars, with ,
displays, unusually for this redshift, damping wing absorption without any
detectable metal lines, which could potentially originate from the IGM. The
other quasar has a high-ionization absorber 0.5 pMpc from the edge of the
proximity zone. This work increases the number of proximity zone measurements
available in the last stages of cosmic reionization to 87. This data will lead
to better constraints on quasar lifetimes and obscuration fractions at high
redshift, which in turn will help probe the seed mass and formation redshift of
supermassive black holes.Comment: 16 pages, 9 figures, Accepted in MNRA
Genome Majority Vote Improves Gene Predictions
Recent studies have noted extensive inconsistencies in gene start sites among orthologous genes in related microbial genomes. Here we provide the first documented evidence that imposing gene start consistency improves the accuracy of gene start-site prediction. We applied an algorithm using a genome majority vote (GMV) scheme to increase the consistency of gene starts among orthologs. We used a set of validated Escherichia coli genes as a standard to quantify accuracy. Results showed that the GMV algorithm can correct hundreds of gene prediction errors in sets of five or ten genomes while introducing few errors. Using a conservative calculation, we project that GMV would resolve many inconsistencies and errors in publicly available microbial gene maps. Our simple and logical solution provides a notable advance toward accurate gene maps
