Efficient Removal of Pharmaceutical Contaminants from Aqueous Solution Using Plant-Derived Biosurfactant-Assisted Dissolved Air Flotation Process.

This study investigates the removal of ibuprofen and diclofenac from aqueous media via a fully pressurized dissolved air flotation system, enhanced by fenugreek-derived saponin, a plant-based biosurfactant. The use of fenugreek saponin in flotation processes distinguishes this work from previous studies as it offers an ecofriendly and efficient alternative to chemical surfactants. The biosurfactant's surface-active properties were confirmed through FT-IR, UV-vis spectroscopy identified key functional groups and structural characteristics of the saponin, NMR provided molecular insights into its bioactive components, and surface tension analyses demonstrated its ability to reduce interfacial tension, indicating effective surfactant behavior.

Current Trends in Modalities of Pain Assessment: A Narrative Review.

Pain is a common complaint among a spectrum of diseases. Although an ideal objective method of pain assessment is lacking, several validated tools are available for use in clinical research and practice. The tool considerations are based upon the parameters to be assessed and factors specific to patient, disease, and availability of instruments.

Role of Gut Microbiome in Neoadjuvant Chemotherapy Response in Urothelial Carcinoma: A Multi-Institutional Prospective Cohort Evaluation.

Treatment with neoadjuvant chemotherapy (NAC) in muscle invasive bladder cancer (MIBC) is associated with clinical benefit in urothelial carcinoma. While extensive research evaluating role of tumor mutational expression profiles and clinicopathologic factors into chemoresponse has been published, the role of gut microbiome (GM) in bladder cancer in chemoresponse has not been thoroughly evaluated. A working knowledge of the microbiome and its effect on all forms of cancer therapy in BC is critical.

Iron doped activated carbon for effective removal of tartrazine and methylene blue dye from the aquatic systems: Kinetics, isotherms, thermodynamics and desorption studies.

In the current research work, the activated carbon synthesized from the plant species Delonix regia is doped with iron oxide nanoparticles and enforced as a nanosorbent for the effective extermination of Tartrazine (TAR) and Methylene blue (MB) dyes. This nanosorbent is prepared from the bark powder of the Delonix regia and subjected to chemical activation; Furthermore, the synthesized biosorbent were characterized using FTIR, SEM, TGA, and XRD to understand their functional properties and structural morphology. The optimum effectiveness adsorption of Tartrazine and Methylene blue has been investigated by using different key parameters.

Recent advancements in the removal/recovery of toxic metals from aquatic system using flotation techniques.

The paramount cause of water scarcity is pollution, which is becoming a massive issue since the last century. Besides, it is evident that water pollution is the main cause of emerging contaminants that are left untreated from industries, can cause serious threats to humans and biota as well. One of the best ways in remediating pollutants and finding a way for generating useable water is to use this contaminated water after the necessary treatment.

Sustainable approach on removal of toxic metals from electroplating industrial wastewater using dissolved air flotation.

This research paper concentrates on the removal of heavy metal from wastewater which was produced from an electroplating industry. Here, the Dissolved Air Flotation (DAF) treatment process is carried out to remove toxic metals such as chromium, cadmium, nickel, lead, and copper using Sodium Dodecyl Sulfate (SDS) as a collector. The best-optimized conditions for the maximum removal of all the metal ions about 97.

Fabrication of novel amine-functionalized magnetic silica nanoparticles for toxic metals: kinetic and isotherm modeling.

In this research, an amine-functionalized magnetic silica nanosorbent was prepared using the co-precipitation technique, and this nanosorbent can be effortlessly detached using an external magnetic field. FTIR and SEM analyses identified that the nanosorbent holds extraordinary adsorption characteristics for toxic metals' (copper, cadmium, zinc, and nickel) removal. The adsorption-affecting parameters were optimized, and the thermodynamic studies assessed that the adsorption process seemed to be spontaneous, feasible, and exothermic.

Malnutrition and Childhood Illness among 1-5-year-old Children in an Urban Slum in Faridabad: A Cross-Sectional Study.

A community-based, cross-sectional study was conducted among 202 children aged 1-5 years residing in an urban slum to study the extent of malnutrition and its association with common childhood illness(es). The participants were selected using convenient sampling (nonprobability), and the appropriate respondents were interviewed using a structured, semi-open-ended, pretested, interviewer-administered questionnaire. The prevalence of undernutrition (weight for age), stunting (height for age), and wasting (weight for height) were calculated at the cutoff level of ≤2 standard deviation (-score <-2) of the National Centre for Health Statistics (NCHS) reference median values.
