Abstract:

Injectable pre-formed physical hydrogels provide many advantages for biomedical applications. Polyelectrolyte complexes (PEC) formed between cationic chitosan (CHT) and anionic polymers of cyclodextrin (PCD) render a hydrogel of great interest. Given the difference between water-soluble (PCDs) and water-insoluble PCD (PCDi) in the extension of polymerization, the present study aims to explore their impact on the formation and properties of CHT/PCD hydrogel obtained from the variable ratios of PCDi and PCDs in the formulation. Hydrogels CHT/PCDi/PCDs at weight ratios of 3:0:3, 3:1.5:1.5, and 3:

Introduction: Vasculogenic impotence is one of the major causes of erectile dysfunction. Cavernosometry and cavernosography is traditionally the gold standard for evaluation of venogenic impotence. However, it is invasive and there are potentially significant complications. Penile colour flow Doppler imaging (PCDI) is non-invasive and can be used to assess venous incompetence. Materials and Methods: One hundred and sixty-eight patients were referred for PCDI assessment from March 1998 to February 2001.

Drought is a complex and interconnected natural phenomenon, involving multiple drought types that mutually influence each other. To capture this complexity, various composite drought indices have been developed using diverse methodologies.

This study proposes an innovative approach by employing Independent Component Analysis (ICA) to develop an ICA-based Composite Drought Index (ICDI), capable of addressing both linear an

Abstract:

Polychlorinated dibezno-p-dioxins (PCDD) and dibenzofurans (PCDF) are compounds with similar structure, physicochemical and toxicological properties. They are not used commercially, they are formed as by-products during certain industrial processes, combustion, failures, etc. LD50 values (0.002-300 mg / kg) depend on the species of animal tested and the chemical structure of the compound. On chronic toxicity, the information available mainly relates to 2,3,7,8-TCDD and 2,3,4,7,8-PeCDF. Potential routes of human exposure are: the digestive system, lungs and skin. These compounds are accumulated

AbstractThree media (sediment, surface water, and dragonfly larvae tissue) were collected from wetlands surrounding an industrial effluent treatment facility prior to closure. Samples were analyzed for metals, total mercury, and polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans (PCDD/PCDF) concentrations. Sediment and surface water concentrations were compared to provincial and federal guidelines, as well as reference wetland concentrations. Exceedances of arsenic, cadmium, chromium, copper, zinc, and PCDD/PCDF guidelines were found in deeper areas of wetlands historically contam

Abstract To investigate the body burden of organochlorine pesticides and dioxins in Japanese women,125 milk samples were collected from 41 mothers in 1994, 42 in 1995, and 42 in 1996. Ofthe 125 samples, 82 were from primipara mothers (first delivery) and 43 were from multipara mothers (second or later delivery). By using capillary gas chromatography with electron capture detection, β-HCH and p,p′-DDE were detected as the major chlorine pesticides in human milk. Average levels of β-HCH and p,p′-DDE were 475 and 368 ng/g lipid, respectively, in primipara breast milk, 314 and 259 ng/g lipid in mu

Abstract:

The problem of increasing farmers’ income has been a hot issue of social concern. Understanding the farmers’ income and the overall development trend is conducive to the rational layout of the social economy and promotes the steady development of a well-off society. Based on this, the paper selects the per capita disposable income (PCDI) of farmers’ households from 2012 to 2019 in 11 cities of Hebei Province as the research object and applies the fractional grey model (FGM (1,1)) to predict farmers’ income from 2020 to 2024. The results show that the farmers’ income will increase in the next f

The concentrations and the congeners between gas phase and particulate phase of polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs) in the air were measured. Samples analysis results showed that the concentration of PCDD/Fs in particulate phase was higher than that in gas phase. The ratio of PCDD to PCDF in gaseous phase and particulate phase was lower than 0.4. The main sources of atmospheric PCDD/Fs in Dalian early spring season were coal-related source.

Abstract:

Large amounts of polychlorinated dibenzo-p-dioxin and furans (PCDD/F), polychlorinated biphenyls (PCB) and polychlorinated benzenes (PCBz) were formed by de novo synthesis using model ashes. The de novo synthesis was affected by SO2and H2O. Knowledge of congener pattern and homologue profiles of PCDD/F, PCB and PCBz is help for elaborating the mechanism of formation and influence of the toxic compounds formed by de novo synthesis. By the help of the component analysis (CA) the best correlated congeners are effectively detected. Various good correlated pairs between PCDD/F, PCB and PCBz have be

Significant prevention of PCDD/PCDF synthesis during the removal of POPs from soil should be ensured by grinding the soil with calcium oxide. The volume of secondary POPs formation also

Some PCB mixtures elicit a spectrum of biochemical and toxic responses in humans and laboratory animals and many of these effects resemble those caused by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and related halogenated aromatic hydrocarbons, which act through the aryl hydrocarbon (Ah)-receptor signal transduction pathway.
