Background: Contamination of freshwater sources can be caused by both anthropogenic and natural processes. According to Central Pollution Control Board, Maharashtra along with 2 other states, contribute 80% of hazardous waste generated in India, including heavy metal pollution. Hence, it is important to quantify heavy metal concentrations in drinking water sources in such areas.
Materials And Methods: Water samples were analyzed for toxic elements (F, As, Cd, Hg, Pb, Ni, Cu, Zn, Mn, and Cr) using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) Agilent 7500. Health risks due to ingestion and dermal contact was assessed. A total of 557 people were randomly selected, with consumers from all 4 types of water sources that is surface water, hand pump, wells, and municipal water. Spot urine samples were collected from 47 people after considering inclusion and exclusion criteria. Urine was collected for estimating mercury and arsenic levels in the study participants.
Results: Arsenic contributes the most health risk from ingestion from water. Among surface water users, 14 people (32%) reported frequent loose stool (-value < .05) (OR 2.5), and 11 people (23%) reported frequent abdominal pain (OR 1.9). Hand pump and well water users reported frequent abdominal pain (27%) (OR 1.4) and gastric discomfort (31%) (-value < .05) (OR 3) respectively. The mean value of urinary Hg and As were 4.91 ± 0.280 and 42.04 ± 2.635 µg/L respectively.
Conclusion: Frequent loose stool, gastric discomfort, and frequent abdominal pain were associated with the various sources of drinking water. Urine Hg levels were found higher than the NHANES (USA) Survey. It is recommended that frequent monitoring of drinking water should be enforced around the industrial hub, so that appropriate actions can be taken if present in excess.

Fusarium solani biomass plays a significant role in water pollution remediation due to its ability to sequester heavy metals, particularly cobalt (Co(II)) and cadmium (Cd(II)), which pose severe environmental and health risks. This study aimed to identify fungi from sewage-contaminated sites and evaluate their efficiency in absorbing and reducing Co(II) and Cd(II) ions. The biosorption potential of irradiated Fusarium solani biomass for removing Co(II) and Cd(II) ions from aqueous solutions was investigated.

Objectives: To compare the plaque reducing efficacy of oil pulling with sesame oil compared to distilled water in a randomized, controlled, examiner-blinded parallel group study.
Materials And Methods: Forty probands without advanced periodontal disease of the University Hospital for Restorative Dentistry and Periodontology, Medical University of Innsbruck (Austria) were randomized allocated to test- (sesame oil) or control group (distilled water) and asked to pull daily in the morning for eight weeks with their allotted fluid for 15 min. Rustogi Modified Navy Plaque Index (RMNPI) and gingival bleeding index were assessed at baseline and after four and eight weeks.

Rapid urbanization in Lahore has dramatically transformed land use and land cover (LULC), significantly impacting the city's thermal environment and intensifying climate change and sustainable development challenges. This study aims to examine the changes in the urban landscape of Lahore and their impact on the Urban thermal environment between 1990 and 2020. The previous studies conducted on Lahore lack the application of Geospatial artificial intelligence (GeoAI) to quantify land use and land cover, which is successfully covered in this study.

This study explores post-COVID BBB permeability changes using a non-contrast water-exchange based MRI and their associations with blood Alzheimer's biomarkers.
Method: Sixty-seven participants were classified based on COVID (COV) and cognitive (COG) statuses into three groups: COV+/COG- (n=34), COV+/COG+ (n=23), and COV- (n=10) for comparisons (COV+: Laboratory-verified SARS-CoV-2 infection; COV-: No history of SARS-CoV-2 infection and negative SARS-CoV-2 nucleocapsid antibody test.
Background: Specimen analysis is crucial for identifying imaging and neuropathological signatures. Histology is the gold-standard, but sample preparation and sectioning induce tissue deformations which hinder quantitative analysis or registration of histology to 3D MRI providing a challenge to the development of MRI biomarkers. Overall, we aim to develop a workflow to correlate histology with high-resolution MRI at a microscopic level (Figure 1), Here, we evaluate a critical step in this process - the section quality from tissue mounting techniques, comparing: A) traditional water bath (Figure 1F), and B) tape transfer (Figure 1G), for the purpose of image segmentation and correlation with high-resolution MRI.
