Potential health, environmental implication of microplastics: A review on its detection.

Microplastic contamination of terrestrial and aquatic environment has gained immense research attention due to their potential ecotoxicity and biomagnification property when enterer into food chain. Heterogenous nature of microplastics coupled with their ability to combine with other emerging pollutants have increased the severity of this crisis. Existing detection methods often fails to accurately quantify the amount of microplastic components present in environmental and biological samples.

The feasibility and acceptability of home phlebotomy for patients with cancer.

Time toxicity is a considerable burden for oncology patients. This study evaluated the feasibility and acceptability of integrating mobile phlebotomy into standard of care procedures. From September 26, 2022, through December 31, 2023, a total of 345 patients had 1464 home laboratory test collection visits completed.

Factors controlling the reactivity of synthetic compound-I Analogs.

A high-valent iron(IV)-oxo porphyrin radical cation (Fe(O)(porph) serves as a key, reactive intermediate for a range of heme enzymes, including cytochrome P450 (CYP), horseradish peroxidase (HRP), and catalase (CAT). Synthetic analogs of this intermediate, known as Compound-I (Cpd-I) in the heme enzyme literature, have been generated with different tetrapyrrolic, macrocyclic ligands, including porphyrin derivatives, and the closely related ring-contracted macrocycles, corroles and corrolazines. These synthetic analogs have been useful for assigning and understanding structural and spectroscopic features and examining the reactivity of Cpd-I-like species in controlled and well-defined environments.

Engineered lignocellulosic based biochar to remove endocrine-disrupting chemicals: Assessment of binding mechanism.

The safety and health of aquatic organisms and humans are threatened by the increasing presence of pollutants in the environment. Endocrine disrupting chemicals are common pollutants which affect the function of endocrine and causes adverse effects on human health. These chemicals can disrupt metabolic processes by interacting with hormone receptors upon consumptions by humans or aquatic species.

Hazard identification of endocrine-disrupting carcinogens (EDCs) in relation to cancers in humans.

Endocrine disrupting chemicals or carcinogens have been known for decades for their endocrine signal disruption. Endocrine disrupting chemicals are a serious concern and they have been included in the top priority toxicants and persistent organic pollutants. Therefore, researchers have been working for a long time to understand their mechanisms of interaction in different human organs.

Axial Ligation Impedes Proton-Coupled Electron-Transfer Reactivity of a Synthetic Compound-I Analogue.

The nature of the axial ligand in high-valent iron-oxo heme enzyme intermediates and related synthetic catalysts is a critical structural element for controlling proton-coupled electron-transfer (PCET) reactivity of these species. Herein, we describe the generation and characterization of three new 6-coordinate, iron(IV)-oxo porphyrinoid-π-cation-radical complexes and report their PCET reactivity together with a previously published 5-coordinate analogue, Fe(O)(TBPCz) (TBPCz = octakis(--butylphenyl)corrolazinato) () (Cho, K. A high-valent iron-oxo corrolazine activates C-H bonds via hydrogen-atom transfer.

Commercialization potential of PET (polyethylene terephthalate) recycled nanomaterials: A review on validation parameters.

Polyethylene Terephthalate (PET) is a polymer which is considered as one of the major contaminants to the environment. The PET waste materials can be recycled to produce value-added products. PET can be converted to nanoparticles, nanofibers, nanocomposites, and nano coatings.

Microbial engineering strategies for synthetic microplastics clean up: A review on recent approaches.

Microplastics are the small fragments of the plastic molecules which find their applications in various routine products such as beauty products. Later, it was realized that it has several toxic effects on marine and terrestrial organisms. This review is an approach in understanding the microplastics, their origin, dispersal in the aquatic system, their biodegradation and factors affecting biodegradation.

Oxygen versus Sulfur Coordination in Cobalt Superoxo Complexes: Spectroscopic Properties, O Binding, and H-Atom Abstraction Reactivity.

A five-coordinate, disiloxide-ligated cobalt(II) ( = 3/2) complex () was prepared as an oxygen-ligated analogue to the previously reported silanedithiolate-ligated Co(MeTACN)(SSiMe) ( , , 3641-3653). The structural and spectroscopic properties of were analyzed by single-crystal X-ray diffraction, electron paramagnetic resonance (EPR), and NMR spectroscopies. The reactivity of with dioxygen was examined, and it was shown to bind O reversibly in a range of solvents at low temperatures.

Blood biomarkers differentiating viral versus bacterial pneumonia aetiology: a literature review.

Background And Objectives: The goal of this literature review is to compare current studies regarding the accuracy of different serum markers in differentiating viral from bacterial pneumonia in the pediatric population with what is employed in the medical settings at present. Currently there is still a lack of significant research, that would give us evaluation on biomarkers benefits towards getting a definite diagnosis of pneumonia. Finding out the potential of biomarkers to differentiate between viral and bacterial pneumonia is also important because knowing the exact pathogen would prevent irrational use of antibiotics.
