RESUMEN

Soil salinization and sodication harm soil fertility and crop production, especially in dry regions. To combat this, using biochar combined with gypsum, lime, and farm manure is a promising solution for improving salt-affected soils. In a pot experiment, cotton stick biochar (BC) was applied at a rate of 20 t/ha in combination with gypsum (G), lime (L), and farm manure (F) at rates of 5 and 10 t/ha. These were denoted as BCG-5, BCL-5, BCF-5, BCG-10, BCL-10, and BCF-10. Three different types of soils with electrical conductivity (EC) to sodium adsorption ratio (SAR) ratios of 2.45:13.7, 9.45:22, and 11.56:40 were used for experimentation. The application of BCG-10 led to significant improvements in rice biomass, chlorophyll content, and overall growth. It was observed that applying BCG-10 to soils increased the membrane stability index by 75% in EC:SAR (2.45:13.7), 97% in EC:SAR (9.45:22), and 40% in EC:SAR (11.56:40) compared to respective control treatments. After BCG-10 was applied, the hydrogen peroxide in leaves dropped by 29%, 23%, and 21% in EC:SAR (2.45:13.7), EC:SAR (9.45:22), and EC:SAR (11.56:40) soils, relative to their controls, respectively. The application of BCG-10 resulted in glycine betaine increases of 60, 119, and 165% in EC: SAR (2.45:13.7), EC: SAR (9.45:22), and EC: SAR (11.56:40) soils. EC: SAR (2.45:13.7), EC: SAR (9.45:22), and EC: SAR (11.56:40) soils all had 70, 109, and 130% more ascorbic acid in BCG-10 applied treatment. The results of this experiment show that BCG-10 increased the growth and physiological traits of rice plants the most when they were exposed to different levels of salt stress. This was achieved by lowering hydrogen peroxide levels, making plant cells more stable, and increasing non-enzymatic activity.

RESUMEN

When the SARS-CoV-2 virus infects humans, it leads to a condition called COVID-19 that has a wide spectrum of clinical manifestations, from no symptoms to acute respiratory distress syndrome. The virus initiates damage by attaching to the ACE-2 protein on the surface of endothelial cells that line the blood vessels and using these cells as hosts for replication. Reactive oxygen species levels are increased during viral replication, which leads to oxidative stress. About three-fifths (~60%) of the people who get infected with the virus eradicate it from their body after 28 days and recover their normal activity. However, a large fraction (~40%) of the people who are infected with the virus suffer from various symptoms (anosmia and/or ageusia, fatigue, cough, myalgia, cognitive impairment, insomnia, dyspnea, and tachycardia) beyond 12 weeks and are diagnosed with a syndrome called long COVID. Long-term clinical studies in a group of people who contracted SARS-CoV-2 have been contrasted with a noninfected matched group of people. A subset of infected people can be distinguished by a set of cytokine markers to have persistent, low-grade inflammation and often self-report two or more bothersome symptoms. No medication can alleviate their symptoms efficiently. Coronavirus nucleocapsid proteins have been investigated extensively as potential drug targets due to their key roles in virus replication, among which is their ability to bind their respective genomic RNAs for incorporation into emerging virions. This review highlights basic studies of the nucleocapsid protein and its ability to undergo liquid-liquid phase separation. We hypothesize that this ability of the nucleocapsid protein for phase separation may contribute to long COVID. This hypothesis unlocks new investigation angles and could potentially open novel avenues for a better understanding of long COVID and treating this condition.

RESUMEN

Since the emergence of SARS-CoV in 2003, researchers worldwide have been toiling away at deciphering this virus's biological intricacies. In line with other known coronaviruses, the nucleocapsid (N) protein is an important structural component of SARS-CoV. As a result, much emphasis has been placed on characterizing this protein. Independent research conducted by a variety of laboratories has clearly demonstrated the primary function of this protein, which is to encapsidate the viral genome. Furthermore, various accounts indicate that this particular protein disrupts diverse intracellular pathways. Such observations imply its vital role in regulating the virus as well. The opening segment of this review will expound upon these distinct characteristics succinctly exhibited by the N protein. Additionally, it has been suggested that the N protein possesses diagnostic and vaccine capabilities when dealing with SARS-CoV. In light of this fact, we will be reviewing some recent headway in the use cases for N protein toward clinical purposes within this article's concluding segments. This forward movement pertains to both developments of COVID-19-oriented therapeutic targets as well as diagnostic measures. The strides made by medical researchers offer encouragement, knowing they are heading toward a brighter future combating global pandemic situations such as these.

RESUMEN

Increasing antimicrobial resistance to the action of existing antibiotics has prompted researchers to identify new natural molecules with antimicrobial potential. In this study, a green system was developed for biosynthesizing gold nanoparticles (BAuNPs) using sage (Salvia officinalis L.) leaf extract bioconjugated with non-toxic, eco-friendly, and biodegradable chitosan, forming chitosan/gold bioconjugates (Chi/BAuNPs). Characterization of the BAuNPs and Chi/BAuNPs conjugates takes place using transmission electron microscopy (TEM), X-ray spectra, Fourier transform infrared (FT-IR) spectroscopy, and zeta potential (Z-potential). The chemical composition of S. officinalis extract was evaluated via gas chromatography/mass spectrometry (GC/MS). This study evaluated the antioxidant and antimicrobial activities of human pathogenic multidrug-resistant (MDR) and multisensitive (MS) bacterial isolates using the agar diffusion method. Chi/BAuNPs showed inhibition of the MDR strains more effectively than BAuNPs alone as compared with a positive standard antibiotic. The cytotoxicity assay revealed that the human breast adenocarcinoma cancer cells (MCF7) were more sensitive toward the toxicity of 5-Fu + BAuNPs and 5-Fu + Chi/BAuNPs composites compared to non-malignant human fibroblast cells (HFs). The study shows that BAuNPs and Chi/BAuNPs, combined with 5-FU NPs, can effectively treat cancer at concentrations where the free chemical drug (5-Fu) is ineffective, with a noted reduction in the required dosage for noticeable antitumor action.

RESUMEN

Urinary tract infection is among the greatest prevalent infections, and it is also one of the most challenging diseases to treat because there are germs that are resistant to several drugs. Antibiotics are typically provided as the treatment; however, there is a disparity in the type of antibiotic that was being prescribed, the amount of the dosage, and the length of time that patients were required to take antibiotics, which led to the creation of multidrug-resistant infections. The objective of this research is to prescribe Fosfomycin treatment for the infection brought by the Escherichia coli bacterium and to determine whether or not it is effective. Throughout the course of this research, the antimicrobial drugs fosfomycin were factored in the equation at various points. The patients who had exhibited symptoms of urinary tract infection provided their urine for the purpose of giving a sample for the studies, which were carried out on them. The results of these studies showed that there were Fosfomycin antimicrobials that were successful in disrupting the E. coli bacteria, and the least inhibitory concentration (MIC) required for the pathogen to be vulnerable was quite low. In addition, administration of fosfomycin intravenously considerably lowers both the bacterial load and the inflammatory infiltration in the kidney and bladder, which helps to preserve the structural integrity of the kidney.

RESUMEN

Aflatoxins are the secondary metabolites produced by Aspergillus flavus and Aspergillus parasiticus and have severe pathological effects on the health of human and animals. The present study was designed to investigate the toxicopathological changes induced by aflatoxins and mitigative potential of Lactobacillus plantarum in broiler birds. One hundred and eighty broiler chicks at one day of age was procured from the local market, and chicks were equally divided into six groups with thirty birds in each group. These birds were treated with aflatoxins (300 and 600 µg/kg) and Lactobacillus plantarum (1 × 108 cfu/kg of feed) in different combinations. The first group was kept as the control, and only a basal diet was provided to birds (BD). In the second group (AF1), the first level of aflatoxins (300 µg/kg) was fed to the birds. In the third group (AF2), the second level of aflatoxins (600 µg/kg) was fed to birds. In the fourth group (AF1LP), Lactobacillus plantarum was given with first level of aflatoxins. In the fifth group (AF2LP), Lactobacillus plantarum was given with the second level of aflatoxins, and in the 6th group (BDLP), Lactobacillus plantarum alone was fed to the chicks. This experimental study was continued for 42 days. Birds were slaughtered after 42 days, and different parameters were assessed. Parameters studied were gain in body weight, organ weight along with some histopathological, hematological, biochemical parameters and residues of aflatoxins in liver and kidney. Lactobacillus plantarum improved the body weight gain and restored the relative organ weight. Hepatic and renal biomarkers returned to normal concentrations, serum proteins were restored in combination group AF1LP, and partial amelioration was observed in the AF2LP group. Red blood cells, white blood cells, hemoglobin centration and packed cell volume became normalized in the AF1LP group, while partial amelioration was observed in the AF2LP group. LP also reduced the concentration of aflatoxin residues in liver kidney and improved the TAC concentrations. The results of this study elucidated the mitigative potential of Lactobacillus plantarum against serum biochemical, histopathological, hematological and toxicopathological changes induced by aflatoxins in the chicks.

RESUMEN

Gut microbial dysbiosis during the development of Hepatitis C virus and liver-related diseases is not well studied. Nowadays, HCV and liver cirrhosis are the major concerns that cause gut bacterial alteration, which leads to dysbiosis. For this purpose, the present study was aimed at correlating the gut bacterial community of the control group in comparison to HCV and liver cirrhotic patients. A total of 23 stool samples were collected, including control (9), liver cirrhotic (8), and HCV (6). The collected samples were subjected to 16 S rRNA Illumina gene sequencing. In comparison with control, a significant gut bacterial alteration was observed in the progression of HCV and liver cirrhosis. Overall, Firmicutes were significantly abundant in the whole study. No significant difference was observed in the alpha diversity of the control and patient studies. Additionally, the beta diversity based on non-metric multidimensional scaling (NMDS) has a significant difference (p = 0.005) (ANOSIM R2 = 0.14) in all groups. The discriminative results based on the LEfSe tool revealed that the HCV-infected patients had higher Enterobacteriaceae and Enterobacterial, as well as Lactobacillus and Bacilli in comparison than the liver-cirrhotic patients. These taxa were significantly different from the control group (p < 0.05). Regarding prospects, a detailed analysis of the function through metagenomics and transcriptomics is needed.

RESUMEN

Noncoding RNAs, such as long noncoding RNAs (lncRNAs), are abundant in livestock. Many lncRNAs that affect the growth rate of livestock have been identified in muscles. However, some of their physiological functions and regulatory mechanisms remain unclear. In this study, we identified a new lncRNA (lncPRRX1) and investigated its effect on the proliferation of bovine myoblasts. LncPRRX1 was highly expressed in muscle tissue, and interference with lncPRRX1 inhibited the proliferation of bovine myoblasts in vitro. The RNA molecules of lncPRRX1 act on miR-137 as competitive endogenous RNAs (ceRNAs). Overexpression of miR-137 suppressed the proliferation of myoblasts, while inhibition of miR-137 had the opposite effect. In addition, the predicted target genes of miR-137 were significantly enriched in the mitogen-activated protein kinase (MAPK) signaling pathway, in which Cell Division Cycle 42 (CDC42) was shown to be the direct target gene of miR-137, and interference with CDC42 inhibited myoblast proliferation. Furthermore, interference with lncPRRX1 repaired the defects in CDC42 protein levels and cell proliferation caused by miR-137 inhibitors. Our results suggested that lncPRRX1 promoted bovine myoblast proliferation by regulating the miRNA-137/CDC42 axis.

RESUMEN

Trichoderma sp. is extensively applied as a beneficial fungus for the management of plant diseases, plant growth promotion, induced resistance, and plays an important role in global sustainable agriculture. This study aimed to enhance the production of microbial xylanase in high titer from the endophytic fungus Trichoderma harzianum kj831197.1, and the cloning of xylanase genes in E. coli DH5α using a pUC19 vector. A combination of glucose, 0.1 mM, Tween 80 with lactose, and 2 mM galactose combined with malt extract boostedthe enzyme production. Xylanase production was maximized at a pH of 5.0, temp. of 30 °C, and agitation of 150 rpm in the presence of malt extract and bagasse as the best nitrogen source and waste, respectively, using submerged fermentation. The molecular weight of highly purified xylanase was 32 KDa, identified using SDS-PAGE. The xylanase gene of T. harzianum kj831197.1 was screened in fungal DNA using definite primers specified in the gene bank database. The identified region was excised using restriction enzymes HindIII and EcoRI and cloned into a pUC19 plasmid vector. Optimization of fermentation conditions improved xylanase production about 23.9-fold.The antifungal efficacy of xylanase toward different phytopathogenic fungi was determined. The highest inhibition was against Corynespora cassiicola, Alternaria sp., Fusarium oxysporum, and Botrytis fabae. This study offered an economical, simple, and efficient method using Trichoderma harzianum kj831197.1 for the production of the xylanase enzyme via the submerged fermentation method.

RESUMEN

BACKGROUND/AIM: Urinary tract infections are commonly caused by the bacteria Escherichia coli and Klebsiella pneumoniae (UTI). The emergence of extended-spectrum -lactamase (ESBL)-producing bacteria strains has made UTI treatment more difficult. MATERIALS AND METHODS: The aim of this study was to characterize E. coli and K. pneumoniae strains' cytotoxic effects, antibiotic sensitivity, interaction with urothelial cells, and reaction to photodynamic therapy. RESULTS: As demonstrated by the higher number of colonies formed, the ESBL + E. coli and K. Pneumonia showed a higher degree of binding with human urothelial cells. With the urothelial cells, K. Pneumonia had the highest binding ability. The cytotoxicity of non-ESBL generating E. coli and K. Pneumonia, on the other hand, was higher. With longer incubation, the discrepancy between the cytotoxic effects of non-ESBL producer and ESBL + E. coli decreased. K. Pneumonia was the opposite. The concentration of ESBL-negative E. coli was easily decreased by photodynamic therapy; however, after a two-hour incubation period, the number of E. coli ESBL + colonies increased from 124 percent to 294 percent. CONCLUSION: With the duration of the incubation period, the number of non-ESBL-producing K. Pneumonia increased. Even with longer incubation times, the number of K. Pneumonia ESBL + colonies decreased, contrary to expectations. The findings show that the two bacterial species differed in terms of cytotoxicity, interaction with urothelial cells, and photodynamic therapy response.
