Expanding roles of cross-talk between hydrogen sulfide and nitric oxide under abiotic stress in plants.

Abiotic stress such as salt, heavy metals, drought, temperature, and others can affect plants from seed germination to seedling growth to reproductive maturity. Abiotic stress increases reactive oxygen species and lowers antioxidant enzymes in plants resulted the plant tolerance ability against stress conditions decrease. Hydrogen sulfide (H2S) and nitric oxide (NO) are important gasotransmitters involved in seed germination, photosynthesis, growth and development, metabolism, different physiological processes and functions in plants. In plants, various enzymes are responsible for the biosynthesis of both H2S and NO via both enzymatic and non-enzymatic pathways. They also mediate post-translation modification, such as persulfidation, and nitrosylation, which are protective mechanisms against oxidative damage. They also regulate some cellular signalling pathways in response to various abiotic stress. H2S and NO also stimulate biochemical reactions in plants, including cytosolic osmoprotectant accumulation, reactive oxygen species regulation, antioxidant system activation, K+ uptake, and Na+ cell extrusion or vacuolar compartmentation. In this review, we summarize how H2S and NO interact with each other, the function of both H2S and NO, the mechanism of biosynthesis, and post-translational modification under different abiotic stress. Our main emphasis was to find the cross-talk between NO and H2S and how they regulate genes in plants under abiotic stress.

Antagonistic potential and biological control mechanisms of Pseudomonas strains against banded leaf and sheath blight disease of maize.

Rhizoctonia solani, the causal agent of banded leaf and sheath blight (BL&SB), poses a significant threat to maize and various crops globally. The increasing concerns surrounding the environmental and health impacts of chemical fungicides have encouraged intensified concern in the development of biological control agents (BCAs) as eco-friendly alternatives. In this study, we explored the potential of 22 rhizobacteria strains (AS1-AS22) isolates, recovered from the grasslands of the Pithoragarh region in the Central Himalayas, as effective BCAs against BL&SB disease. Among these strains, two Pseudomonas isolates, AS19 and AS21, exhibited pronounced inhibition of fungal mycelium growth in vitro, with respective inhibition rates of 57.04% and 54.15% in cell cultures and 66.56% and 65.60% in cell-free culture filtrates. Additionally, both strains demonstrated effective suppression of sclerotium growth. The strains AS19 and AS21 were identified as Pseudomonas sp. by 16S rDNA phylogeny and deposited under accession numbers NAIMCC-B-02303 and NAIMCC-B-02304, respectively. Further investigations revealed the mechanisms of action of AS19 and AS21, demonstrating their ability to induce systemic resistance (ISR) and exhibit broad-spectrum antifungal activity against Alternaria triticina, Bipolaris sorokiniana, Rhizoctonia maydis, and Fusarium oxysporum f. sp. lentis. Pot trials demonstrated significant reductions in BL&SB disease incidence (DI) following foliar applications of AS19 and AS21, with reductions ranging from 25 to 38.33% compared to control treatments. Scanning electron microscopy revealed substantial degradation of fungal mycelium by the strains, accompanied by the production of hydrolytic enzymes. These findings suggest the potential of Pseudomonas strains AS19 and AS21 as promising BCAs against BL&SB and other fungal pathogens. However, further field trials are warranted to validate their efficacy under natural conditions and elucidate the specific bacterial metabolites responsible for inducing systemic resistance. This study contributes to the advancement of sustainable disease management strategies and emphasizes the potential of Pseudomonas strains AS19 and AS21 in combating BL&SB and other fungal diseases affecting agricultural crops.

Chitosan lecithin nanocomposite based electrochemical biosensor for glycine detection in biological matrices.

Increased glycine concentrations are associated with altered metabolism of cancer cells and is reflected in the bodily fluids of the brain cancer patients. Various studies have been conducted in past to detect glycine as an imaging biomarker via NMR Spectroscopy tools. However, the use is limited because of the low concentration and different in vivo detection due to overlapping of peaks with myo-inositol in same spectral position. Alongside, little is known about the electrochemical potential of Glycine as a biomarker for brain cancer. The prime impetus of this study was to check the feasibility of glycine as non-invasive biomarker for brain cancer. A divergent approach to detect glycine "non-enzymatically" via unique chitosan lecithin nanocomposite has been utilised during this study. The electrochemical inactivity at provided potential that prevented glycine to get oxidized or reduced without mediator was compensated utilising the chitosan-lecithin nanocomposite. Thus, a redox mediator (Prussian blue) was used for high sensitivity and indirect detection of glycine. The chitosan nanoparticles-lecithin nanocomposite is used as a matrix. The electrochemical analysis of the onco-metabolomic biomarker (glycine) utilizing cyclic voltammetry in glycine spiked multi-Purpose artificial urine was performed to check distribution of glycine over physiological range of glycine. A wide linear range of response varying over the physiological range from 7 to 240 µM with a LOD 8.5 µM was obtained, showing potential of detection in biological samples. We have further evaluated our results via simulating the interaction of mediator and matrix with Glycine by HOMO-LUMO band fluctuations.

Multi-oligomeric and catalytically compromised serine acetyltransferase and cysteine regulatory complex of Mycobacterium tuberculosis.

l-cysteine, a primary building block of mycothiol, plays an essential role in the defense mechanism of Mycobacterium tuberculosis (Mtb). However, it is unclear how Mtb regulates cysteine biosynthesis as no study has reported the cysteine regulatory complex (CRC) in Mtb. Serine acetyltransferase (SAT) and cysteine synthase (CS) interact to form CRC. Although MtCS has been characterized well, minimal information is available on MtSAT, which synthesizes, O-acetylserine (OAS), the precursor of cysteine. This study fills the gap and provides experimental evidence for the presence of MtCRC and a non-canonical multi-oligomeric MtSAT. We employed multiple analytical methods to characterize the oligomeric and kinetic properties of MtSAT and MtCRC. Results show that MtSAT, lacking >75 N-terminal amino acids exists in three different assembly states; trimer, hexamer, and dodecamer, compared to the single hexameric state of SAT of other bacteria. While hexamers display the highest catalytic turnover, the trimer is the least active. The predominance of trimers at low physiologically relevant concentrations suggests that MtSAT displays the lowest catalytic potential known. Further, the catalytic potential of MtSAT is also significantly reduced in CRC state, in contrast to enhanced activity of SAT in CRC of other organisms. Our study provides insights into multi-oligomeric MtSAT with reduced catalytic potential and demonstrates that both MtSAT and MtCS of Mycobacterium interact to form CRC, although with altered catalytic properties. We discuss our results in light of the altered biochemistry of the last step of canonical sulfate-dependent cysteine biosynthesis of Mycobacterium.

Assessment of nutritional status and habitual dietary intake of Indian farm women: Evidence from a case study in central India.

OBJECTIVES: Nutritional security for women working in agriculture is one of the most serious and persisting concerns in developing countries like India. The present study surveyed the dynamics of nutritional status based on dietary intake, namely calorie, carbohydrate, protein, fat, calcium, folic acid, iron, vitamin, carotene, etc., in the farm women in the central India state of Madhya Pradesh. METHODS: A total of 225 farm women (ages 18 to 60 y) who were engaged in agricultural activities were selected for this study. The nutritional survey was done by personal interview on food intake with a pretested interview schedule and daily dietary intake. The survey questionnaire includes information on family, socioeconomic status, income, education, occupation, and food habits of the farm women. As "daily dietary intake", respondents were asked to list all foods and beverages consumed for a whole day. RESULTS: The mean age, height, weight, and body mass index of the respondents were 34.93 y, 1519 mm, 49.47 kg, and 21.5 kg/m2, respectively. Based on different grades of nutrition, body mass index results indicated that 28% were underweight, 52.4% were normal, 17.8% were overweight, and 1.8% were obese. Inequality (estimated by Gini coefficient) analysis found that there is not much variation in the nutrient intake levels across the physical status of the respondents, with the exception of carotene and vitamin C. The classification and regression tree analysis indicated that with the exception of fat, the rest of the nutrients were not significant in determining the farm women's physical status in terms of weight. In the analysis of the waist-to-hip ratio, the risk of metabolic diseases (cardiovascular disease, diabetes, etc.) was higher in the 31- to 40-y age group. CONCLUSIONS: Overall food frequency indicated that poor intake of micronutrients in their diet according to their work activity results in poor health status. The study affirmed that the actual intake of nutrients varied significantly across the physical status of the farm women, their physical activities carried out, and their monthly income level. The study also suggests various policy options to overcome the nutritional gap in farm women.

The continuum of liver injury with severity of dengue fever: A retrospective observational study.

BACKGROUND: Dengue is a major international health concern prevalent in tropical and sub-tropical countries. There are a paucity of studies on the relationship of hepatic complications with inflammatory parameters in dengue infection. METHODS: Single-centre observational study was conducted at the tertiary care centre in North India. Patients (>12 years) diagnosed with dengue infection between August and November 2021 were enrolled in the study. The frequency of hepatic derangements and their associations with inflammatory severity was analysed. RESULTS: Based on the clinical symptoms, 170 patients were classified into three categories, namely, dengue fever, warning dengue and severe dengue. Higher incidence of liver dysfunction was observed in severe dengue patients with median values of aspartate aminotransferase (AST) (3051 U/L, p < 0.001), alanine aminotransferase (ALT) (1792 U/L, p = 0.009), alkaline phosphatase (172 U/L, p = 0.001), T.Bil (34.2 µmol/L, p < 0.001), albumin (30 g/L, <0.001), and gamma-glutamyl transferase (152 U/L, p < 0.001) along with inflammatory marker C-reactive protein (CRP) (43 mg/dL, p < 0.001) highly deranged, in comparison to patients with/without warning signs. Median levels of CRP were found to be positively and significantly correlated with the median levels of AST and ALT (p < 0.05, r = 0.99) in all three categories of dengue patients. Liver injury was noted in 107 (63%) of the cohort, and mixed type of liver injury involving both hepatocellular and cholestatic patterns was observed as the most common type of injury (n = 50, 29.4%). Liver injury correlated with the severity of dengue illness as about 85% of severe dengue patients had significant liver injury (p = 0.014). CONCLUSION: In dengue patients, the association of the liver injury with inflammatory severity suggests that the mechanism of liver injury may be related to inflammatory response apart from the hepatotropic nature of the virus.

Factors associated with thrombo-hemorrhagic deaths in patients with Acute Promyelocytic leukemia treated with Arsenic Trioxide and all-trans retinoic acid.

Acute Promyelocytic Leukemia (APL) is associated with excellent long-term outcomes. However, early mortality due to coagulopathy remains a challenge. In this study we examined the bleeding and thrombotic manifestations, as well as incidence of Early Death secondary to thrombosis/hemorrhage (ED-TH) in patients with APL. Early death (ED) was defined as death occurring within 30 days of induction therapy. Two-hundred forty-eight patients were included in the study. Overall, 57 patients had evidence of a major bleed/thrombosis at presentation or during induction therapy, including 44 patients with a major bleed, 8 patients with thrombosis and 5 patients with both evidence of thrombosis and a major bleed. Forty patients (16.1%) had ED, of which 21 had ED-TH. The cumulative incidence of death due to thrombo-hemorrhagic complications at 30 days was 8.4%. On univariate analysis, increasing Prothrombin time (PT)(p-<0.001), white blood cell count (p < 0.001) and activated Partial thromboplastin time (aPTT) (p < 0.001) were statistically significantly associated with increased risk of ED-TH. However, on multivariate analysis, only increasing PT (p-0.025) and aPTT (p-0.041) were significantly associated with increased risk of ED-TH.

Unveiling the microbial diversity and functional dynamics of Shiv Kund, Sohna hot spring, India through a shotgun metagenomics approach.

In this research, we examined the microbial diversity in Sohna hot spring, Haryana, India using shotgun metagenome sequencing based on the Illumina Hiseq 4000 sequencing technology. The raw sequence data from metagenomic paired-end libraries were analysed for taxonomic classification, diversity, and functional annotation using MG-RAST online server. The results showed the presence of total of 57 phyla, 931 genera, and 2068 species, predominantly occupied by Moraxellaceae (Gammaproteobacteria). However, at the species level, we reported the presence of some representative pathogenic taxa, such as Acinetobacter baumannii and Moraxella osloensis. The functional annotation predicted at various levels based on SEED-based subsystem, KEGG ortholog identity (KO), Cluster of Orthologous Groups (COGs) database identified the predominance of genes associated with primary and secondary metabolism along with a crucial role in environmental and genetic signals, cellular communication, and cell signalling. Comparative Genome Analysis (CGA) using The Pathosystem Resource Integration Centre (PATRIC) tool based on genome annotation and assembly of the metagenomic libraries for representative taxon Acinetobacter baumannii (NCBI tax id:470) characterized the reads with a unique genome identifier of 470.20380 (A. baumannii DDLJ4) which is evolutionary closer to A. baumannii ATCC 470.17978 400667.7. In addition, the CARD database results about the presence of potential AMR pathotypes and the prevalence of adeABC, adeIJK, abeM gene-specific clusters that function as multidrug efflux pumps. Overall, the results provided a comprehensive insight into virulence and anti-microbial resistance mechanism and could be useful for developing potential drug targets against the possible AMR pathotypes.

Sustainability in the global value chain-a scientometric analysis.

For its promise in enhancing sustainability, the global value chain (GVC) has grown in relevance and sparked many studies. Due to different value activities in multiple countries and industry clusters, the competition and cooperation among value chains have attracted the considerable attention of business leaders and academicians worldwide. GVC-related sustainability research is a niche area despite its widespread presence in the literature. To bridge the gap, we use scientometric analysis in this paper, examining the corpus of 753 articles published in Web of Science journals from 2001 till 2021. This review illuminates the research performance constituents (e.g., most prolific authors, nations, institutions, and journals), the themes and issues that underpin the fields' intellectual structure, and transforming discoveries. GVC depends on nine basic clusters for sustainability research (i.e., global value chain participation, gendered global production network, repositioning organisational dynamics, labour stands, learning opportunities, Internet era). Future studies can be conducted to generate new knowledge across ten thematic (based on keywords) clusters (i.e., market liberalisation, trade pollution nexus, value chain dynamics, global value chain reconfiguration, non-governmental organisation, multipolar governance). A model that encompasses current knowledge of the global value chain for sustainability is developed, and avenues for future research are provided.

Remediation of contaminants from wastewater using algal nanoparticles via green chemistry approach: an organized review.

Bio-nanotechnology is one of the new and sound techniques that have various advantages over conventional methods of wastewater treatment. The utilization of nanomaterials like nanoparticles for wastewater treatment is emerging field of research. Both physical and chemical methods can be used for nanoparticle synthesis, but synthesis based on algae (biological method) has numerous advantages over others as it is environmentally friendly and sustainable. Top-down and bottom-up are the two approaches used for nanoparticle synthesis, generally, bio-reduction (bottom-up approach) is used to synthesize nanoparticles. Nanoparticles can be synthesized inside the cell of algae called intracellular synthesis and outside on the surface of the cell called extracellular synthesis. Temperature, pH, and reaction time are some of the factors that can influence the synthesis, size, and properties of nanoparticles. Characterization of nanoparticles is carried out with the help of the techniques like UV-visible spectroscopy (UV-vis), x-ray diffraction, Fourier transfer infrared spectroscopy, etc. Algal nanoparticles are highly efficient in the remediation of contaminants like heavy metals and dyes from wastewater. In the present review, the utilization of algal nanoparticles for wastewater treatment containing contaminants like heavy metals, and dye, and various methods of synthesis of nanoparticles from algae are discussed. Moreover, the challenges and opportunities present in this field are also highlighted. As this field is in its initial stage, therefore, a lot of research gaps are present, which can only be filled by further new research.

Systematic studies on the effect of structural modification of orange peel for remediation of phenol contaminated water.

In the present study, orange peel biochar has been utilized as the adsorbent for the removal of phenol from contaminated water. The biochar was prepared by thermal activation process at three different temperature 300, 500 and 700°C and are defined as B300, B500, and B700 respectively. The synthesized biochar has been characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transformation infrared spectroscopy (FTIR), RAMAN spectroscopy, X-ray photoelectron spectroscopy (XPS), and UV-Vis spectroscopy. SEM analysis revealed a highly irregular and porous structure for B700 as compared with others. The parameters such as initial phenol concentration, pH, adsorption dosage, and contact time were optimized, and the maximum adsorption efficiency and capacity of about 99.2% and 31.0 mg/g was achieved for B700 for phenol adsorption. The Branauer-Emmett-Teller (BET) surface area and Berrate-Joyner-Halenda (BJH) pore diameter obtained for B700 were about 67.5 m2 /g and 3.8 nm. The adsorption of phenol onto the biochar followed Langmuir isotherm showing linear fit with R2 = 0.99, indicating monolayer adsorption. The kinetic data for adsorption is best fitted for pseudo-second order. The thermodynamic parameters ΔG°, ΔH°, and ΔS° values obtained are negative, which means that the adsorption process is spontaneous and exothermic. The adsorption efficiency of phenol marginally declined from 99.2% to 50.12% after five consecutive reuse cycles. The study shows that the high-temperature activation increased the porosity and number of active sites over the orange peel biochar for efficient adsorption of phenol. PRACTITIONER POINTS: Orange peel is thermally activated at 300, 500, and 700°C for structure modification. Orange peel biochars were characterized for its structure, morphology, functional groups, and adsorption behavior. High-temperature activation improved the adsorption efficiency up to 99.21% due to high porosity.

Long-term real-world outcomes of patients with acute promyelocytic leukaemia treated with arsenic trioxide and all-trans retinoic acid without chemotherapy-a retrospective, single-centre study.

Arsenic trioxide (ATO) and all-trans retinoic acid (ATRA) form the backbone of the treatment of acute promyelocytic leukaemia (APL), with the addition of chemotherapy for high-risk patients. We describe our experience of treating patients with APL of all risk classes with ATO and ATRA without chemotherapeutic agents. Patients received induction with ATO and ATRA followed by three cycles of consolidation with ATO and ATRA (each 1 month apart) after achieving morphological remission. Patients with intermediate- and high-risk disease received a further 2 years of maintenance with ATRA, 6-mercaptopurine and methotrexate. A total of 206 patients were included in the study. The majority of the patients were intermediate risk (51.9%), followed by high risk (43.2%). Differentiation syndrome was seen in 41 patients (19.9%). Overall, 25 patients (12.1%) died within 7 days of initiating therapy. Seven patients relapsed during follow-up. The mean (SD) estimated 5-year event-free survival (EFS) and overall survival (OS) in the entire cohort was 79% [5.8%] and 80% [5.8%] respectively. After excluding patients who died within 7 days of therapy initiation, the mean (SD) estimated 5-year EFS and OS was 90% [5.8%] and 93% [3.9%] respectively. Our study shows that treatment of all risk classes of APL with ATO and ATRA without chemotherapy is associated with excellent long-term outcomes in the real-world setting.

Clinico-Epidemiologic Characteristics of Patients Reported in the Mycotic Infections in COVID-19 Registry.

We update results from the Mycotic Infections in COVID-19 (MUNCO) Registry, May-September 2021.

Comparative evaluation of implant stability with and without autologous platelet-rich fibrin prior to prosthetic loading - A split-mouth randomized clinical trial.

Context: Status of bone-implant interface or osseointegration can be assessed by using resonance frequency analysis (RFA), which measures implant stability. A modified implant surface can significantly enhance osseointegration and reduce healing period. Platelet-rich fibrin (PRF) consists of fibrin mesh with entrapped platelets and leukocytes that release a huge number of growth factors which contribute to wound healing and tissue regeneration. Aims: The present study aims to evaluate the effect of PRF on osseointegration in terms of implant stability. Settings and Design: This was a split-mouth randomized clinical trial. Materials and Methods: Sixty surgical sites were divided randomly into two groups. In Group 1 (thirty sites), PRF was placed in osteotomy sites before implant placement whereas no PRF was placed in Group 2 (thirty sites). Stability was measured using RFA in terms of implant stability quotient (ISQ) at baseline, 1 week, 1 month, and 3 months. Statistical Analysis: Intergroup comparison was done using Mann-Whitney U-test. Intragroup comparison was done using Friedman's test followed by pairwise comparison using Wilcoxon signed-rank test. Results: On intergroup comparison, Group 1 showed higher values for ISQ which were statistically significant (P < 0.05) at 1 week and 1 month. No significant difference (P > 0.05) was found at baseline and 3 months. Intragroup comparison and further pairwise comparison revealed a highly significant difference for values between all pairs of time intervals (P < 0.01) with higher values at 3 months. Conclusions: PRF has a significant effect on osseointegration of dental implants during the early healing period prior to loading.

COVID-19 associated variations in liver function parameters: a retrospective study.

BACKGROUND: Characteristics of laboratory findings of COVID-19 patients are of great significance for diagnosis and treatment. Studies that have analysed the variations in hepatic profile in correlation with the inflammatory markers in SARS-CoV-2 are limited. METHODS: We retrospectively analysed liver function tests and inflammatory markers of 170 admitted patients with confirmed COVID-19 in the tertiary care centre, Post Graduate Institute of Medical Education and Research (PGIMER), India, using Roche Cobas Autoanalyzer. RESULTS: Number of patients with normal liver enzyme levels were 63 (41.5%), while with raised levels of any of the liver enzymes were 89 (58.5%), out of which 43 (48.31%) had liver injury which manifested as increased severity in terms of intensive care unit (ICU) requirement (p=0.0005). Significantly raised levels of liver enzymes and liver injury were observed with age (p<0.0001) and in males (p=0.004). Significantly decreased levels of albumin and total proteins and increased levels of total bilirubin (p<0.0001) were seen in patients with abnormal liver enzyme levels and liver injury as compared to patients with normal levels. Significant increase in the levels of alanine transaminase and gamma-glutamyl transferase was seen on the 7th day, CRP and ferritin (p<0.0001) peaks were observed on 2nd and 3rd day respectively. A significant positive correlation was found between the levels of these inflammatory markers and liver function parameters. CONCLUSIONS: More than half of patients admitted to the hospital with SARS-CoV-2 infection had an abnormal liver function which was found to be associated with raised levels of inflammatory markers. Significantly higher proportions of patients with abnormal liver function were elderly and males and were at higher risk of progressing to severe disease.
