Mineral pollutants and coliform contamination in groundwater pose health risks to consumers: a spatiotemporal study in a mining-impacted area.

The presence of mineral pollutants, combined with bacterial contamination, has significantly impacted groundwater quality and led to various health-related issues in mining-impacted areas. Therefore, we measured the concentration of fluoride (F), phosphate (PO), sulphate (SO), ammonium (NH), nitrate (NO), the total coliforms (TCs), and physiochemical characteristics in groundwater samples of South Khorasan, Eastern Iran. For this, we collected water samples from 100 wells in spring and autumn across this mining-impacted area.

Spatial health risk assessments of nickel in the groundwater sources of a mining-impacted area.

Mining activities have increased the potential risks of metal pollution to the groundwater resources in arid areas across the globe. Therefore, this study aimed to examine the health risk associated with nickel (Ni) in the groundwater sources of a mining-impacted area, South Khorasan, Eastern Iran. A total of 110 stations were included in the study, comprising 62 wells, 40 qanats, and 8 springs in summer, 2020.

Spiritual care competency and its relationship with clinical self-efficacy in nursing students.

Background: Spiritual care occupies a special place in holistic care and improving the quality of services provided to patients. The component of clinical self-efficacy is recognized as a prerequisite for clinical capacity and competency. The current study determined the level of spiritual care competency and its relationship with clinical self-efficacy in nursing students.

Hydrochemical evaluation of groundwater quality and human health risk assessment of trace elements in the largest mining district of South Khorasan, Eastern Iran.

The groundwater resources of mining areas have been in a challenging condition in terms of metal pollution and human health. Therefore, this study investigated the concentration of cobalt (Co), molybdenum (Mo), selenium (Se), tin (Sn), and antimony (Sb) in groundwater samples (wells, qanats, and springs) in a heavily contaminated mining district, South Khorasan, Eastern Iran. Human health risk of the studied metals to target groups was assessed, and water quality of the studied groundwater was investigated in the study area.

Serum and gene expression profile of cytokines following combination of yoga training and vitamin D supplementation in breast cancer survivors: a randomized controlled trial.

Background: This study aimed to examine the effect of the combination of yoga training with high vitamin D dose supplementation on the expression and systemic levels of inflammatory cytokines and psychophysical status of breast cancer survivors.

Methods: Thirty volunteered breast cancer survivors (48 ± 8 years) were randomly allocated to a high dose (4000 IU) of vitamin D supplementation (HD) group (n = 10), yoga with a high dose of vitamin D (YHD) group (n = 10), and yoga with a low dose (2000 IU) of vitamin D (YLD) group (n = 10). Participants performed the Hatha yoga style for 12 weeks, twice a week.

Health risk assessment of total chromium in the qanat as historical drinking water supplying system.

This study investigated the health risk assessment of total chromium (Cr) in qanats of South Khorasan, Eastern Iran. For this, concentration of Cr in a total of 83 qanats were measured in summer 2020. Samples were initially tested in the field for temperature, pH, dissolved oxygen (DO), electrical conductivity (EC), and total dissolved solids (TDS).

Promising Chemoprevention of Colonic Aberrant Crypt Foci by Muscle and Shell Extracts in Azoxymethane-Induced Colorectal Cancer in Rats.

Background And Purpose: This study subjected a rat model to the extracts of muscle and shell tissues from Portunus segnis to assess their therapeutic effects on the HT-29 colon cancer cells as well as on colonic Aberrant Crypt Foci (ACF) induced by Azoxymethane (AOM).

Methods: The cell line was exposed to the extracts to compare the cytotoxicity of hexane, butanol, ethyl acetate, and water extract of muscle and ethanolic extract of the shell. Male rats (n=40) were assigned into control, positive, negative, and treatment groups.
