Synthesis of highly luminescent core-shell nanoprobes in a single pot for ofloxacin detection in blood serum and water.

Antibiotics are commonly used as antibacterial medications due to their extensive and potent therapeutic properties. However, the overconsumption of these chemicals leads to their accumulation in the human body via the food chain, amplifying drug resistance and compromising immunity, thus presenting a significant hazard to human health. Antibiotics are classified as organic pollutants. Therefore, it is crucial to conduct research on precise methodologies for detecting antibiotics in many substances, including food, pharmaceutical waste, and biological samples like serum and urine. The methodology described in this research paper introduces an innovative technique for producing nanoparticles using silica as the shell material, iron oxide as the core material, and carbon as the shell dopant. By integrating a carbon-doped silica shell, this substance acquires exceptional fluorescence characteristics and a substantial quantum yield value of 80%. By capitalising on this characteristic of the substance, we have effectively constructed a fluorescent sensor that enables accurate ofloxacin analysis, with a detection limit of 1.3 × 10-6 M and a linear range of concentrations from 0 to 120 × 10-6 M. We also evaluated the potential of CSIONPs for OLF detection in blood serum and tap water analysis. The obtained relative standard deviation values were below 3.5%. The percentage of ofloxacin recovery from blood serum ranged from 95.52% to 103.28%, and from 89.9% to 96.0% from tap water.

Comparing Feto-Maternal Outcomes in Pregnant Women With Normal and Abnormal Liver Function Tests: A Prospective Observational Study.

INTRODUCTION: Pregnant women with abnormal liver function tests (LFTs) require proper evaluation and timely management to reduce maternal and fetal morbidity and mortality. OBJECTIVE: The present study was done with the objective of determining feto-maternal outcomes in antenatal women with abnormal LFTs and comparing them with antenatal women having normal liver function. The prevalence and possible causes of derangements in LFT were also identified. METHOD: Pregnant women referred to an antenatal clinic for several reasons pertaining to abnormal liver functions, and those admitted to the labor room for delivery with abnormal LFTs were included in the study. The pregnant women with abnormal LFT were studied prospectively, and they were compared with pregnant women having normal LFT. The fetal and maternal outcomes were also noted. RESULTS:  The pregnant women attending the antenatal clinic with a history of pruritus, abdominal pain, jaundice, nausea/vomiting, hypertension ascites, etc. and delivered at our facility were evaluated. One hundred and eight women had abnormal LFT defined by criteria laid down in material and methods. Eighty-seven women with normal LFT were taken for comparison. In the abnormal LFT, the main cause was intrahepatic cholestasis of pregnancy (IHCP). There were 6 (5.5%) maternal deaths in this group and none in the normal LFTs. There were 6 (5.6%) fetal deaths and 4 (4.6%) in the other group (p-value=1). The prevalence of abnormal LFT was 9.11% throughout pregnancy. Increased bilirubin and alkaline phosphatase (ALP) were significantly correlated with maternal mortality, while gestational age at birth, presence of meconium, appearance, pulse, grimace, activity, and respiration (APGAR) score, maternal mortality, and raised alkaline phosphatase level were found to be significantly associated with fetal mortality. CONCLUSION: Patients with abnormal LFT were significantly associated with maternal morbidity and mortality. However, fetal outcomes in patients with abnormal and normal LFT were similar. Hyperbilirubinemia and raised alanine aminotransferase (ALT) were significant predictors of maternal mortality.

Caregiver's perceptions of COVID-19 vaccination, and intention to vaccinate their children against the disease: a questionnaire based qualitative study.

Coronavirus disease 2019 (COVID-19) vaccine side effects have an important role in the hesitancy of the general population toward vaccine administration. Another reason for vaccine hesitancy might be that healthcare professionals may not address their concerns regarding vaccines appropriately. Regardless, hesitancy in the form of delay, refusal, or acceptance with doubts about its usefulness can limit the downward trajectory of the COVID-19 pandemic. Therefore, the authors conducted a national cross-sectional study (n=306) to assess causes and concerns for vaccine hesitancy in caregivers in Pakistan toward getting their children vaccinated. The questions identified caregivers by socioeconomic demographics, perceived COVID-19 pandemic severity, and concerns toward the COVID-19 vaccine. The majority of the participants were 45-59 years of age (42.8%) with a mean age of 36.11 years (SD: 7.81). A total of 80% of these participants were willing to vaccinate their child with any COVID-19 vaccine. Present comorbidities had a frequency of 28.4% (n=87/306) and only 26.9% (n=66/245) participants were willing to vaccinate their child. Participants with high social standing were 15.4% (n=47/306) with the majority of them being willing to vaccinate their children (45/47). Socioeconomic status (OR:2.911 [0.999-8.483]), and the child's vaccinations being up to date (OR:1.904 [1.078-3.365]) were found to be independent factors for caregivers to be willing to vaccinate their child. Around 62% (n=191/306) were not willing to vaccinate due to the concern for side effects, 67.6% (n=207/306) were not willing because they did not have ample information available, and 51% (n=156/306) were not willing as they were concerned about vaccine effectiveness. Further studies on vaccine safety in the pediatric population are required to improve caregivers' perceptions.

Personal protective equipment and micro-nano plastics: A review of an unavoidable interrelation for a global well-being hazard.

The usage and the demand for personal protective equipments (PPEs) for our day-to-day survival in this pandemic period of COVID-19 have seen a steep rise which has consequently led to improper disposal and littering. Fragmentation of these PPE units has eventually given way to micro-nano plastics (MNPs) emission in the various environmental matrices and exposure of living organisms to these MNPs has proven to be severely toxic. Numerous factors contribute to the toxicity imparted by these MNPs that mainly include their shape, size, functional groups and their chemical diversity. Even though multiple studies on the impacts of MNPs toxicity are available for other organisms, human cell line studies for various plastic polymers, other than the most common ones namely polyethylene (PE), polystyrene (PS) and polypropylene (PP), are still at their nascent stage and need to be explored more. In this article, we cover a concise review of the literature on the impact of these MNPs in biotic and human systems focusing on the constituents of the PPE units and the additives that are essentially used for their manufacturing. This review will subsequently identify the need to gather scientific evidence at the smaller level to help combat this microplastic pollution and induce a more in-depth understanding of its adverse effect on our existence.

Growth performance of different forestry species irrigated with moderately saline wastewater.

A seven month, pot study was conducted to evaluate the impact of moderately saline wastewater on the growth potential of six forestry plant species viz., Eucalyptus calmaldulensis, Dendrocalamus strictus, Casurina equisetfolia, Cassia fistula, Melia dubia, and Bambusa arundinacea under different drainage conditions namely, well-drained saline (WDS) condition and poor-drained saline condition (PDS) and the control with well-drained non-saline condition. WDS treatment resulted in no mortality whereas PDS treatment resulted in mortality in the range of 33-66%. The plant height and root dry biomass increased in the range of 145% to 221.6% and 4.3-37.1 g respectively in WDS treatment, however, 23.60% to 173.4% and 4.1-10.1 g in PDS treatment. Among all, Eucalyptus camaldulensis and Dendrocalamus strictus showed high Na+ accumulation in roots (2.16 ± 0.02% and 1.13 ± 0.01%), shoots (1.98 ± 0.01% and 0.74 ± 0.01%) and leaves (1.27 ± 0.02% and 0.86 ± 0.01%) in WDS treatment and in case of PDS treatment root (1.01 ± 0.01% and 0.23 ± 0.01%), shoot (1.12 ± 0.02% and 0.11 ± 0.01%), and leaf (0.07 ± 0.01% and 0.1 ± 0.02). The overall performance of both Eucalyptus camaldulensis and Dendrocalamus strictus was highest in WDS treatment. Therefore, it was concluded, that both plants had better performance than other plant species, a proper drainage system defines the overall productivity and treatment efficiency.

Forestry is not only a necessity for increasing tree cover and decreasing pressure on natural forests but also a most desired land use plan especially for reclaiming and rehabilitating the degraded lands. This study concluded that salt-affected and waterlogged areas and moderately saline waters can be utilized satisfactorily in raising forests using suitable plant species. Eucalyptus camaldulensis and Dendrocalamus strictus which showed good performance for salt tolerance and survival can be effectively used to mitigate the problems of waterlogged conditions and soil salinity remediation. Utilizing these species extensively can be a sustainable and suitable approach to promote afforestation and mitigate the problems of waterlogged conditions and for green belt development.

Cyclic volatile methyl siloxanes (D4, D5, and D6) as the emerging pollutants in environment: environmental distribution, fate, and toxicological assessments.

Cyclic volatile methyl siloxanes (cVMS) have now become a subject of environmental contamination and risk assessment due to their widespread use and occurrence in different environmental matrices. Due to their exceptional physio-chemical properties, these compounds are diversely used for formulations of consumer products and others implying their continuous and significant release to environmental compartments. This has captured the major attention of the concerned communities on the grounds of potential health hazards to human and biota. The present study aims at comprehensively reviewing its occurrence in air, water, soil, sediments, sludge, dusts, biogas, biosolids, and biota and their environmental behavior as well. Concentrations of cVMS in indoor air and biosolids were higher; however, no significant concentrations were observed in water, soil, and sediments except for wastewaters. No threat to the aquatic organisms has been identified as their concentrations do not exceed the NOEC (maximum no observed effect concentration) thresholds. Mammalian (rodents) toxicity hazards were not very evident except for the occurrence of uterine tumors in very rare cases under long-term chronic and repeated dose exposures in laboratory conditions. Human relevancy to rodents were also not strongly enough established. Therefore, more careful examinations are required to develop stringent weight of evidences in scientific domain and ease the policy making with respect to their production and use so as to combat any environmental consequences.

Field validated biomarker (ValidBIO) based assessment of impacts of various pollutants in water.

The sensitivity of fish towards pollutants serves as an excellent tool for the analysis of water pollution. The effluents generated from various anthropogenic activities may contain heavy metals, pesticides, microplastics, and persistent organic pollutants (POPs) and ultimately find its way to aquatic environment. The enzymatic activities of fish collected from water bodies near major cities, oil spillage sites, agricultural land, and intensively industrialized areas have been reported to be significantly impacted in various field studies. These significant alterations in enzymatic activities act as a biomarker for monitoring purposes. The use of biomarkers not only helps in the identification of known and unknown pollutants and their detrimental health impacts, but also identifies the interaction between pollutants and organisms. The conventional method majorly used is physicochemical analysis, which is recognized as the backbone of the system for monitoring water quality. In physicochemical monitoring, major problems exist in assessing or predicting biological effects from chemical or physical data. Xenobiotic-induced enzymatic changes in fish may serve as an intuitive and efficient biomarker for determining contaminants in water bodies. Therefore, field validated biomarker (ValidBIO) approach needs to be integrated in water quality monitoring program for environmental health risk assessment of aquatic life impacted due to various point and non-point sources of water pollution.

Electrophysiological and Visual Parameter Changes in Retinitis Pigmentosa Patients undergoing Autologous Platelet-Rich Plasma Therapy: A Randomized Control Trial.

Purpose: To assess the efficacy of autologous platelet-rich plasma (PRP) injections in suprachoroidal space and subtenon space in cases of retinitis pigmentosa, which is a genetic disease, leading to gradual loss of vision. Till date, no treatment is available. Methods: Seventy-eight eyes of 39 patients of retinitis pigmentosa having visual acuity ranging from reading of Early Treatment Diabetic Retinopathy Study (ETDRS) chart from 1 m onward to patients who were not able to read the ETDRS chart but whose visual acuity ranged from finger count close to face to <1 m were included in the study. The left and right eyes of each patient were randomized as the intervention eye and control eye. 0.2 mL of autologous PRP was injected in suprachoroidal space and 0.5 mL of PRP was injected in subtenon space of the intervention eye taking aseptic precautions. Injections were repeated at 15-day intervals up to 3 injections. Results: Majority of patients were in the age group of 18-30 years (20 cases) followed by 31-45 years (13 cases) and more than 45 years (6 cases). Intervention eyes showed a statistically significant improvement in visual acuity and multifocal electroretinography (mfERG). Improvement was noted in amplitude density latency and in ring ratio of mfERG. There was a significant improvement in best-corrected visual acuity (BCVA). However, no improvement in mfERG or BCVA was observed in the control group. Conclusions: Gene therapy may be the ultimate cure for retinitis pigmentosa, but it is unaffordable for many patients due to its high cost. PRP may be recognized as a modality to improve vision and stop further deterioration, especially in cases where functional vision is preserved. Negligible treatment costs and affordability will give power to economically disadvantaged patients.

Cardiovascular disease in pregnancy and its outcome: A prospective study.

Introduction: Prevalence estimates place maternal heart illness anywhere from 0.3 to 3.5 percent. Up to 20.5% of all maternal deaths of non-obstetrical cause are attributable to cardiovascular disease. Aim: The aim of the study was the management of patients with the multidisciplinary approach to maternal cardiovascular disease and its influence on maternal and fetal outcomes in a tertiary care centre. Objectives: 1. To find out the prevalence and spectrum of heart disease in Pregnancy. 2. To find out the outcome of pregnancy with heart disease in a tertiary care centre. Materials and Methods: This prospective study of one year was done on pregnant with heart disease coming to the Obstetrics and Gynaecology department in collaboration with the cardiology department of IGIMS, Patna. A study was done on 65 pregnant with heart disease between the age group 20 to 35 years were compared to a control group of 65 pregnant women who were hospitalised during the same time period but did not have heart disease. All the pregnant women with heart disease were included in this study. Patients with medical disorders like Kidney disease, Liver disease, Pulmonary Disease, Diabetes Mellitus were excluded from the study. We used IBM's SPSS v23 to analyse the collected data. Result: Prevalence of heart disease in pregnancy was 5.8% in present study and mostly of RHD (62.5%), followed by corrected CHD (12.5%) and CHD (10.9%). Patients of NYHA Class I and II (58.5%), Class III (26.2%), and Class IV (15.4%). The mitral valve was most often impacted by RHD (35.3% of all cases), followed by the tricuspid valve (15.0%). Eight (1.1%) people had cardiac surgery for therapeutic reasons. Six percent of all corrective surgeries included closing an atrial septal defect (ASD). The most common kind of congenital abnormality was a ventricular septal defect (VSD, 3%), followed by atrial septal defect (ASD, 1.5%) and pulmonary ductal atresia (PDA, 1.5%). Patients with heart disease had a higher rate of MTP, emergency LSCS and instrumental births than the controls. Deaths during pregnancy were 4 (6.2%) with cardiac disease and no maternal mortality in control group and all belonged to NYHA Class 4 were anaemic. In patients with a left ventricular ejection fraction of 45% or below, death was high. Two women died intrapartum from RHD, and two died postpartum from Peripartum cardiomyopathy. There were significantly more incidences of low-birth-weight infants (36.4%) compared to the control group (p = 0.001). Cases had a statistically significant greater frequency of obstetric problems, as well as an increased risk of developing anaemia, hypertension, hypothyroidism, cholestasis, FGR, and GDM (p-value 0.017). Multiparity, severe valvular lesion, NYHA function class III or IV, arrhythmia, and low ejection fraction were associated with poor maternal outcome in the current study. Conclusion: Maternal morbidity and mortality due to heart disease can be reduced appreciably by antenatal care, early diagnosis, and management with the help of cardiologists and surgery in selected cases.

Self-assembled DNA nanostructure containing oncogenic miRNA-mediated cell proliferation by downregulation of FOXO1 expression.

FOXO1 transcription factor not only limits the cell cycle progression but also promotes cell death as a tumor suppressor protein. Though the expression of FOXO1 is largely examined in breast cancer, the regulation of FOXO1 by miRNA is yet to be explored. In the current study, self-assembled branched DNA (bDNA) nanostructures containing oncogenic miRNAs were designed and transfected to the MCF7 cell line to decipher the FOXO1 expression. bDNA containing oncogenic miRNAs 27a, 96, and 182 synergistically downregulate the expression of FOXO1 in MCF7 cells. The down-regulation is evident both in mRNA and protein levels suggesting that bDNA having miRNA sequences can selectively bind to mRNA and inhibit translation. Secondly, the downstream gene expression of p21 and p27 was also significantly downregulated in presence of miR-bDNA nanostructures. The cell proliferation activity was progressively increased in presence of miR-bDNA nanostructures which confirms the reduced tumor suppression activity of FOXO1 and the downstream gene expression. This finding can be explored to design novel bDNA structures which can downregulate the tumor suppressor proteins in normal cells and induce cell proliferation activity to identify early-phase markers of cancer.

Role of serum C-reactive protein (CRP)/Albumin ratio in predicting the severity of acute pancreatitis: A retrospective cohort.

Acute pancreatitis is a disease with a wide spectrum of severity, complications, and outcome with severe life-threatening complications develop in patients leading to high mortality in severe acute pancreatitis. The rationale of this study is to diagnose the severity of acute pancreatitis using a single test ratio, i.e., CRP/albumin ratio which is a combination of markers for systemic inflammation and nutritional status. All those patients with age group 16-80 years who were diagnosed with acute pancreatitis and admitted subsequently to ICU were included. Severe pancreatitis was determined as CT severity score above 7. About 41% patients out of total 225 had severe pancreatitis. CRP/albumin ratio >4.35 had a sensitivity of 87% and accuracy of 76% to predict acute severe pancreatitis. Elevated CRP/albumin ratio was also associated with complications like multi-organ failure OR: 2.31 [1.3-4.2], duodenal thickening OR: 2.25 [1.2-4.2], and ascites OR: 2.90 [1.5-5.6]. Although, the severity of this elevation varied with different age groups, such non-invasive and readily available parameters should be relied upon admission to risk stratify the patients suffering from pancreatitis. CRP/albumin ratio has higher sensitivity and negative predictive value to predict severe pancreatitis than CRP alone and hence give additional advantage as a prognostic marker, although Delong's test to compare AUROC was indifferent (P-value: 0.22).

Use of enzymatic biomarkers of Labeo rohita to study the effect of polybrominated diphenyl ether (BDE- 209) via dietary exposure in laboratory conditions.

Fishes have been widely used as a representative to estimate the health of an aquatic ecosystem. In the present study, Labeo rohita was selected for biomarker study against decabromodiphenyl ether (BDE-209), a persistent organic pollutant (POP), as it is a widely used Indian carp. The results suggested significant effects on the optimum metabolism of Labeo rohita. After 48 to 72 h of exposure, most of the biomarkers such as lactate dehydrogenase (LDH), creatine kinase (CK), serum glutamic pyruvic transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT), and hepatosomatic index (HSI) increased drastically indicating the higher index of tissue and liver damage. On the contrary, succinic dehydrogenase (SDH), acetylcholinesterase (AChE), and alkaline phosphatase (ALP) showed a reverse trend suggesting the shifting of fish metabolism towards anaerobic respiration mode because of induced stress. Increased catalase (CAT) activity was also observed, which indicated increased abundance of reactive hydroxyl species and therefore a possible oxidative stress in fishes. It is further suggested to understand and examine the biotransformation characteristics and degradation pathways of polybrominated diphenyl ether (PBDE)s, which would be useful to comprehend their environmental fate.

Effect of Different Organic Substrates on Selected Life History Traits and Nutritional Composition of Black Soldier fly (Hermetia illucens).

Black soldier fly (Hermetia illucens L. [Diptera: Stratiomyidae]) has gained huge popularity in different industrial and commercial sectors because of its excellent potential to treat organic waste and high biomass production. As the industrial application of BSF is expanding at accelerated rates, there is a need to optimize its mass scale production where the organic substrates play a very crucial role in optimal growth and development. The present study deals with the investigation of different life history attributes of BSF such as larval and adult weights, survival, pupation rate, and the development time as the function of different organic substrates [fruits and vegetable mix (T1); wheat bran, soy, and corn meal mix (T2); and the dairy manure (T3)]. The larval, pupal, and adult weights differed across all three treatments (P < 0.05). There was no significant difference in the survival rate of larvae among T1 and T2 however, T3 differed significantly from T1 and T2. Likewise, the pupation rate and the development time differed significantly between the three treatments. Results indicated that the BSF development was least in dairy manure treatment and therefore, higher percent mortality and higher development time were observed. However, to deal with the problems of waste management and treatment, BSF larvae can be successfully employed for the treatment of any type of waste since it showed significant treatment efficiencies.

Surface-Enhanced Biocompatibility and Adsorption Capacity of a Zirconium Phosphate-Coated Polyaniline Composite.

The present study deals with the synthesis, characterization, and testing of a novel composite, zirconium(IV) phosphate-coated polyaniline (ZrPO4@PANI), toward the adsorption- and surface-controlled toxicity applications. Following the synthesis of the ZrPO4@PANI composite using the sol-gel route, various characterization techniques such as Fourier transform infrared spectroscopy, scanning electron microscopy, and powder X-ray diffraction were employed to confirm its surface functionality, morphology and agglomeration, and crystallinity and crystal nature, respectively. The composite was found to be effective toward the adsorptive removal of the methylene blue dye (an organic pollutant) as against the changes in the dye concentration, dose, pH, and so forth. Also, to understand the MB adsorption kinetics, the experimental data were evaluated using the Langmuir and Freundlich models and the results were described in accordance with the Langmuir isotherm model (an adsorption capacity of 120.48 mg/g at ambient temperature). In addition, the tests conducted using pseudo-first- and pseudo-second-order kinetic models confirmed the existence of pseudo-second-order rates. Furthermore, the calculation of thermodynamic parameters for the MB adsorption, namely, changes in enthalpy, entropy, and Gibbs' free energy, exhibited a spontaneous, feasible, and exothermic nature. Finally, the comparative studies of in vitro toxicity and flow cytometry confirmed that the copresence of ZrPO4 along with PANI significantly improved the biocompatibility. The outcome of the experimental results implies that the composite is capable enough of serving as the safe and low-cost adsorbent, in addition to supporting the effective capping of the surface toxicity of PANI.

A Modified Lysimeter Study for Phyto-Treatment of Moderately Saline Wastewater Using Plant-Derived Filter Bedding Materials.

The present study focuses on determining the phyto-treatment efficiency for treatment of moderately saline wastewater using organic raw materials, such as rice husk, coconut husk, rice straw, and charcoal. The moderately saline wastewater with total dissolved solids (TDS) concentration up to 6143.33 ± 5.77 mg/L was applied to the lysimeters at the rate of 200 m3 ha-1 day-1 in five different lysimeter treatments planted with Eucalyptus camaldulensis (T1, T2, T3, T4, and T5). T1 was a control without any filter bedding material, whereas rice straw, rice husk, coconut husk, and charcoal were used as filter bedding materials in the T2, T3, T4, and T5 treatment systems, respectively. Each treatment showed significant treatment efficiency wherein T3 had the highest removal efficiency of 76.21% followed by T4 (67.57%), T5 (65.18%), T2 (46.46%), and T1 (45.5%). T3 and T4 also showed higher salt accumulation, such as sodium (Na) and potassium (K). Further, the pollution load in terms of TDS and chemical and biological oxygen demand significantly reduced from leachate in the T3 and T4 treatments in comparison with other treatments. Parameters of the soil, such as electrical conductivity, exchangeable sodium percentage, and cation exchange capacity did not show values corresponding to high salinity or sodic soils, and therefore, no adverse impact on soil was observed in the present study. Also, Eucalyptus camaldulensis plant species showed good response to wastewater treatment in terms of growth parameters, such as root/shoot weight and nitrogen, phosphorus, and potassium (NPK) uptake, plant height, biomass, and chlorophyll content. Root and shoot dry weight were in the order T3 (51.2 and 44.6 g)>T4 (49.3 and 43.5 g) > T5 (47.6 and 40.5 g) > T2 (46.9 and 38.2 g) > T1 (45.6 and 37.1 g). Likewise, the total chlorophyll content was highest in T3 (12.6 µg/g) followed by T4 (12.3 µg/g), T5 (11.9 µg/g), T2 (11.5 µg/g), and the control, that is, T1 (11.0 µg/g). However, the most promising results were obtained for T3 and T4 treatments in comparison with the control (T1), which implies that, among all organic raw materials, coconut and rice husks showed the highest potential for salt accumulation and thereby wastewater treatment. Conclusively, the findings of the study suggest that organic raw material-based amendments are useful in managing the high salts levels in both plants and leachates.

Regulatory roles of RNA modifications in breast cancer.

Collectively referred to as the epitranscriptome, RNA modifications play important roles in gene expression control regulating relevant cellular processes. In the last few decades, growing numbers of RNA modifications have been identified not only in abundant ribosomal (rRNA) and transfer RNA (tRNA) but also in messenger RNA (mRNA). In addition, many writers, erasers and readers that dynamically regulate the chemical marks have also been characterized. Correct deposition of RNA modifications is prerequisite for cellular homeostasis, and its alteration results in aberrant transcriptional programs that dictate human disease, including breast cancer, the most frequent female malignancy, and the leading cause of cancer-related death in women. In this review, we emphasize the major RNA modifications that are present in tRNA, rRNA and mRNA. We have categorized breast cancer-associated chemical marks and summarize their contribution to breast tumorigenesis. In addition, we describe less abundant tRNA modifications with related pathways implicated in breast cancer. Finally, we discuss current limitations and perspectives on epitranscriptomics for use in therapeutic strategies against breast and other cancers.

Current available treatment technologies for saline wastewater and land-based treatment as an emerging environment-friendly technology: A review.

Different industrial activities such as agro-food processing and manufacturing, leather manufacturing, and paper and pulp production generate highly saline wastewater. Direct discharge of saline wastewater has resulted in pollution of waterbodies by very high magnitudes. Consequently, an enormous number of pollutants such as heavy metals, salts, and organic matter are also released into the environment threatening the survival of human and biota. Saline wastewater also has significant effects on survival of plants, agricultural activities, and groundwater systems. Several treatments and disposal technologies are available for saline wastewater, but the selection of the most appropriate treatment and disposal technology still remains a major challenge with respect to the economic or technical constraints. Considering the sustainable management of saline wastewater, the present review is an attempt to compile the existing and emerging technologies for the treatment of saline wastewater. Among all the individual and hybrid technologies, land-based treatment systems are proven to be the most efficient technologies considering the energy demands, economic, and treatment efficiencies. Likewise, new and sustainable technologies are the need of hour integrating both the treatment and management and the resource recovery factors along with the ultimate goal of the protection in terms of human health and environmental aspect. PRACTITIONER POINTS: Physico-chemical treatment technologies for saline wastewater. Combined/Hybrid technologies for the treatment of saline wastewater. Land-based treatments as the environment friendly and sustainable method for saline wastewater treatment and disposal. Role of phytoremediation in land-based treatment.
