Notes

The entire mitochondrial genomes of 5 Eimeria types infecting household bunnies.
The peroxidase, phenylalanine ammonia-lyase and chitinase enzymes were found to be the most active defence enzymes with 0.19,7.28 and 118.16 U/min/ml/mg protein compared to 0.01, 4.99 and 62.22 U/min/ml/mg protein for control. Hence, the current study suggest that ChNP, a non-toxic biodegradable biopolymer, can be an effective biocontrol agent against ShB caused by R.solani. It is a potent plant immunity booster that can be used as a suitable alternative to commercially available chemical fungicides. Further field trials in this respect are needed to determine the dosage for their application in rice fields.The increasing incidence of skin cancer (SC) is a global health concern. The commonly reported side effects and resistance mechanisms have imposed the pursuit for new therapeutic alternatives. Moreover, additional preventive strategies should be adopted to strengthen prevention and reduce the rising number of newly SC cases. This review provides relevant insights on the role of p53 tumour suppressor protein in melanoma and non-melanoma skin carcinogenesis, also highlighting the therapeutic potential of p53-targeting drugs against SC. In fact, several evidences are provided demonstrating the encouraging outcomes achieved with p53-activating drugs, alone and in combination with currently available therapies in SC. Another pertinent perspective falls on targeting p53 mutations, as molecular signatures in premature phases of photocarcinogenesis, in future SC preventive approaches. Overall, this review affords a critical and timely discussion of relevant issues related to SC prevention and therapy. Importantly, it paves the way to future studies that may boost the clinical translation of p53-activating agents, making them new effective alternatives in precision medicine of SC therapy and prevention.Over the past decades, tumor-resident immune cells have been extensively studied to dissect their biological functions and clinical roles. Tumor-infiltrating CD8+ T cells, because of their cytotoxic and killing ability, have been under the spotlight for a long time, whereas CD4+ T cells are considered just a supporting actor in the field of cancer immunotherapy. Until recently, accumulating evidence has demonstrated the ability of CD4+ T cells in eradicating solid tumors, and their functions in mediating antitumor immunity have been investigated in various orientations. In this review, we highlight the pivotal role of CD4+ T cells in eliciting vigorous antitumor immune responses, summarize key signaling axes and molecular networks behind these antitumor functions, and also propose possible targets and promising strategies which might translate into more efficient immunotherapies against human cancers.The seasonal variation in chemical and lipid composition of chub mackerel (Scomber colias) was evaluated monthly over one year (proximate chemical composition and lipid profile fatty acid (FA) and lipid classes distribution). Significant seasonal changes regarding fat content were noticed (1.3-10.3 g/100 g), with the lowest fat content obtained in February (during spawning period), and the highest in September. Regarding the FA profile, the main fluctuations were recorded in saturated (SFA) and polyunsaturated fatty acids (PUFA). The highest SFA content was registered between March and August (25.3-32.3%). PUFA (the most abundant group) reached its maximum percentual content between December and February (60.9 and 66.9%, respectively). In absolute terms, PUFA attained 5352.6 mg/100 g edible part in September, where 2473.8 mg/100 g of docosahexaenoic acid (DHA, C226n-3), representing 46.2% of total PUFA. DHA lowest level was 519.8 mg/100 g, registered in low-fat chub mackerel. Go6976 Together DHA and EPA (eicosapentaenoic acid, C205n-3) represented 75% of the total PUFA and 84% of n-3 PUFA. Triacylglycerols (TAG) with 82.2-92.1% of total lipid content) and phospholipids (4.4-8.4%) were the main lipid classes. Polar lipid fraction (phospholipids), was predominantly constituted by PUFA (68.6-74.5%), mainly DHA (45.2-55.1%), with the highest percentage recorded in low-fat chub mackerel. High relative contents of PUFA (36.6-49.1%) were also found in TAG. Having into account the data obtained, chub mackerel is a privileged source of DHA even in a lean species whereby its consumption should be recommended as part a healthy dietary regime.Lipoxygenases (LOX) are non-heme iron-containing enzymes that catalyze regio- and stereo-selective dioxygenation of polyunsaturated fatty acids (PUFA). Mammalian LOXs participate in the eicosanoid cascade during the inflammatory response, using preferentially arachidonic acid (AA) as substrate, for the synthesis of leukotrienes (LT) and other oxidized-lipid intermediaries. This review focus on lipoxygenases (LOX) structural and kinetic implications on both catalysis selectivity, as well as the basic and clinical implications of inhibition and interactions with nitric oxide (•NO) and nitroalkenes pathways. During inflammation •NO levels are increasingly favoring the formation of reactive nitrogen species (RNS). •NO may act itself as an inhibitor of LOX-mediated lipid oxidation by reacting with lipid peroxyl radicals. Besides, •NO may act as an O2 competitor in the LOX active site, thus displaying a protective role on lipid-peroxidation. Moreover, RNS such as nitrogen dioxide (•NO2) may react with lipid-derived species formed during LOX reaction, yielding nitroalkenes (NO2FA). NO2FA represents electrophilic compounds that could exert anti-inflammatory actions through the interaction with critical LOX nucleophilic amino acids. We will discuss how nitro-oxidative conditions may limit the availability of common LOX substrates, favoring alternative routes of PUFA metabolization to anti-inflammatory or pro-resolutive pathways.An epidemic caused by COVID-19 in China turned into pandemic within a short duration affecting countries worldwide. Researchers and companies around the world are working on all the possible strategies to develop a curative or preventive strategy for the same, which includes vaccine development, drug repurposing, plasma therapy, and drug discovery based on Artificial intelligence. Therapeutic approaches based on Computational biology and Machine-learning algorithms are specially considered, with a view that these could provide a fast and accurate outcome in the present scenario. As an effort towards developing possible therapeutics for COVID-19, we have used machine-learning algorithms for the generation of alignment kernels from diverse viral sequences of Covid-19 reported from India, China, Italy and USA. Using these diverse sequences we have identified the conserved motifs and subsequently a peptide library was designed against them. Of these, 4 peptides have shown strong binding affinity against the main protease of SARS-CoV-2 (Mpro) and also maintained their stability and specificity under physiological conditions as observed through MD Simulations.
