Meta-Analysis Review
Environmental DNA (eDNA) has been used in a variety of ecological studies and management applications. The rate at which eDNA decays has been widely studied but at present it is difficult to disentangle study-specific effects from factors that universally affect eDNA degradation. To address this, a systematic review and meta-analysis was conducted on aquatic eDNA studies. Analysis revealed eDNA decayed faster at higher temperatures and in marine environments (as opposed to freshwater). DNA type (mitochondrial or nuclear) and fragment length did not affect eDNA decay rate, although a preference for <200 bp sequences in the available literature means this relationship was not assessed with longer sequences (e.g. >800 bp). At present, factors such as ultraviolet light, pH, and microbial load lacked sufficient studies to feature in the meta-analysis. Moving forward, we advocate researching these factors to further refine our understanding of eDNA decay in aquatic environments.

Review
BACKGROUND
Recently, the usefulness of thiol/disulfide homeostasis (TDH) in various diseases is being widely investigated. In this mini-review, our aim is to clarify the role of TDH in clinical practice in the light of current literature.
METHODS
We performed a systematic review of the existing literature describing the clinical utility of TDH in the clinical setting. MEDLINE, EMBASE, and CINAHL were used as data sources. Two reviewers conducted independent screening and data extraction. Use of TDH in each system was investigated separately.
RESULTS
A total of 35 studies were detected in this mini-review. Our results revealed the protective role of TDH and its utility as a diagnostic marker in many common diseases in clinical practice.
CONCLUSIONS
Maintenance of TDH as a crucial part of antioxidant defense system is critical in diagnosis and prognosis of potentially lethal diseases.

Meta-Analysis Review
Fluoride exposure may cause changes in blood pressure, but this conclusion is controversial. Therefore, this meta-analysis aims to investigate the potential relationship between fluoride exposure and blood pressure or hypertension. PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), WANFANG MED ONLINE, and Chinese Scientific Journals Full-Text Databases (VIP) were searched; in addition, two related studies were added manually. In total, 7 observational studies were identified, the pooled odds ratios (ORs) for hypertension between high and reference fluoride exposure groups were calculated, and the pooled standardized weighted mean difference (SMD) of systolic blood pressure (SBP) and diastolic blood pressure (DBP) was estimated using an inverse-variance weighted random-effects model; next, sensitivity analysis and subgroup analysis were used to assess potential sources of heterogeneity; furthermore, publication bias was assessed using the Begg and Egger test. In brief, there were no statistical differences between exposure groups and control groups in terms of blood pressure or hypertension when all included studies considered. However, subgroup analysis indicated that blood pressure will rise with the increase of fluoride exposure concentrations in endemic fluorosis areas. The corresponding pooled SMD estimates were 0.31 (95% CI 0.11, 0.51) and 0.27 (95% CI 0.11, 0.43) for SBP and DBP. Funnel plots suggested no asymmetry. Our findings support the possibility of a positive correlation between fluoride exposure and blood pressure in endemic fluorosis areas. Additional evidence is needed to assess the dose-response relationship between fluoride exposure and blood pressure.

Review
The present systematic review is aimed at evaluating the diuretic effects determined according to the natural mineral water consumption on healthy individuals. This systematic review has been performed following the guidelines of the PRISMA (preferred reporting items for systematic reviews and meta-analyses) Statement, investigating PubMed, Scopus, Web of Science and Cochrane Library from inception to November 2022. Studies performed both on animals and on humans were considered. After screening, a total of 12 studies have been identified. Of these, 11 studies were performed in Italy and 1 in Bulgaria. The time range of publication is very wide, ranging from 1962 to 2019 for human studies and from 1967 to 2001 for animal studies. All the included studies found an increase in diuresis determined according to the consumption of natural mineral water, in some cases after just one administration of the tested water. However, the quality of the studies is not so high, especially for the research conducted many years ago. Thus, it would be desirable to carry out new clinical studies using more appropriate methodological approaches and more refined methods of statistical data processing.

Review
Renal fibrosis, characterised by glomerulosclerosis and tubulointerstitial fibrosis, is a typical pathological alteration in the progression of chronic kidney disease (CKD) to end-stage renal disease (ESRD). However, the limited and expensive options for treating renal fibrosis place a heavy financial burden on patients and healthcare systems. Therefore, it is significant to find an effective treatment for renal fibrosis. Ferroptosis, a non-traditional form of cell death, has been found to play an important role in acute kidney injury (AKI), tumours, neurodegenerative diseases, and so on. Moreover, a growing body of research suggests that ferroptosis might be a potential target of renal fibrosis. Meanwhile, mitophagy is a type of selective autophagy that can selectively degrade damaged or dysfunctional mitochondria as a form of mitochondrial quality control, reducing the production of reactive oxygen species (ROS), the accumulation of which is the main cause of renal fibrosis. Additionally, as a receptor of mitophagy, NIX can release beclin1 to induce mitophagy, which can also bind to solute carrier family 7 member 11 (SLC7A11) to block the activity of cystine/glutamate antitransporter (system Xc-) and inhibit ferroptosis, thereby suggesting a link between mitophagy and ferroptosis. However, there have been only limited studies on the relationship among mitophagy, ferroptosis and renal fibrosis. In this paper, we review the mechanisms of mitophagy, and describe how ferroptosis and mitophagy are related to renal fibrosis in an effort to identify potential novel targets for the treatment of renal fibrosis.

Review
Chlorine dioxide (ClO) has emerged as a broad-spectrum, safe, and effective disinfectant due to its high oxidation efficiency and reduced formation of organochlorinated by-products during application. This article provides an updated overview of ClO-based oxidation processes used in water treatment. A systematic review of scientific information and experimental data on ClO-based water purification procedures is presented. Concerning ClO-based oxidation derivative problems, the pros and cons of ClO-based combined processes are assessed and disinfection by-product (DBP) control approaches are proposed. The kinetic and mechanistic data on ClO reactivity towards micropollutants are discussed. ClO selectively reacts with electron-rich moieties (anilines, phenols, olefins, and amines) and eliminates certain inorganic ions and microorganisms with high efficiency. The formation of chlorite and chlorate during the oxidation process is a crucial concern when utilizing ClO. Future applications include the combination of ClO with ferrous ions, activated carbon, ozone, UV, visible light, or persulfate processes. The combined process can reduce by-product generation while still ensuring ClO sterilization and disinfection. Overall, this research could provide useful information and new insights into the application of ClO-based technologies.

Review
Amphibian populations globally are in decline. One great threat is the abstraction of water resources that alter surface-water hydrology. Conservation actions aimed at restoring or manipulating surface water are employed as a management tool, but empirical evidence on the effectiveness of these approaches is scarce. In this systematic review, we summarized the global experience of manipulating water for amphibian conservation. We explored examples of manipulating water to conserve amphibian species and communities. Approaches varied in their frequency of implementation and in their success. Extending hydroperiod to match larval requirements showed encouraging results, as did off-season drying to control predators. Spraying water into the environment showed several potential applications, but successes were limited. Despite some promising interventions, we identified few (n = 17) empirically supported examples of successful water manipulation to benefit amphibians. It is unclear whether this stems from publication bias or if it is an artifact of language selection. However, manipulating water shows some potential in amphibian conservation, particularly at sites with a proximal water source and in regions where aridity is increasing due to climate change. Regardless of the scale of the intervention or its perceived probability of success, high-quality reporting of empirical results will further understanding of how water manipulations can benefit threatened amphibian populations.

Meta-Analysis Review
We summarized epidemiological studies assessing sodium in drinking water and changes in blood pressure or hypertension published in English from 1960 to 2015 from PubMed, Scopus, and Web of Science. We extracted data on blood pressure level or prevalence of hypertension and calculated pooled estimates using an inverse variance weighted random-effects model. The pooled standardized mean difference (SMD) in 7 studies (12 data sets) comparing the low and high water sodium exposure groups for systolic blood pressure (SBP) was 0.08 (95% CI, -0.17 to 0.34) and for diastolic blood pressure (DBP) was 0.23 (95% CI, 0.09-0.36). Of the 3 studies that assessed the association between high water sodium and odds of hypertension, 2 recent studies showed consistent findings of higher risk of hypertension. Our systematic review suggests an association between water sodium and human blood pressure (more consistently for DBP) but remain inconclusive because of the small number of studies (largely in young populations) and the cross-sectional design and methodological drawbacks. In the context of climate-change-related sea level rise and increasing saltwater intrusion into drinking water sources, further research is urgently warranted to investigate and guide intervention in this increasingly widespread problem.
