Environmental risk assessment methodology for urban tropical lagoons based on feasible lines of evidence under limited resources conditions: Jacarepaguá Lagoon/Brazil.

Determining environmental risk levels posed to different urban lagoon can provide an important overview regarding the relative severity of the environmental degradation of these ecosystems, increasing the risks visibility, which can be used as an important decision-making tool to prioritize investments. Jacarepaguá Lagoon (JPAL) is part of a coastal lagoon system comprising four interconnected lagoons in Rio de Janeiro city, Southeastern Brazil. Real estate speculation and insufficient sanitation infrastructure resulted in untreated sewage discharge into this ecologically sensitive lagoon system.

Multicentric Cross-Sectional Survey to Assess the Variation of Fractionation Strategies Used in the Management of Head and Neck Cancers in the Asian Region (INNOCENCE-ASIA).

Purpose: Head and neck cancers (HNCs) are in general treated with conventional fractionation regimen of 1.8-2 Gy per fraction. Altered fractionation (ALFT) strategies such as hypofractionation radiotherapy (HYPO-RT), accelerated fractionation radiotherapy (AFRT), and hyperfractionation radiotherapy (HFRT) have not been practiced uniformly across centers in different parts of the world.

Safety of pre-operative venogram for hemodialysis access planning in pre-end-stage kidney disease patients.

Background: Although conventional pre-operative venography can accurately delineate venous anatomy as an alternative to ultrasound for hemodialysis access planning, it may carry a risk of contrast-induced acute kidney injury (AKI) and progression of renal failure in chronic kidney disease (CKD) patients not yet on dialysis. Therefore, the objective of this study was to evaluate the safety and efficacy of pre-operative venograms in pre-end-stage kidney disease (ESKD) patients.

Methods: We performed a retrospective cohort study (2018-2022) of consecutive pre-ESKD patients who underwent staged bilateral venograms for preoperative vein mapping prior to hemodialysis access creation at a tertiary care medical center.

We present the complete chloroplast genome of the eelgrass from Monterey, California. The genome is circular and 144,675  bp in length. It consists of 82 protein-coding, 31 transfer RNA, and 8 ribosomal RNA genes and is 99.

Panchromatic Absorption of Unsymmetrical Donor-Acceptor Dyes Based on a Meta-conjugated 1,3,5-Heteroaryltriazine Core.

Attachment of three different heterocycles with electron donor or acceptor character to a central 1,3,5-triazine core generates readily soluble side-chain free dyes with two displaying soft crystalline mesomorphism and one displaying a nematic liquid crystal phase as confirmed by polarized optical microscopy, calorimetry, gravimetric analysis, and powder X-ray diffraction. Equally intriguing is the dyes' relatively strong electronic communication between donor and acceptor subchromophores that are meta-conjugated to one another, which is experimentally observed as a broad intramolecular charge-transfer absorption that can extend over 100 nm past the most intense absorption event and is computationally confirmed through density functional theory (DFT) evaluations of the molecular ground- and excited-state properties. This molecular design permits the preparation of dyes with panchromatic absorption not just based on the additive absorption of individual subchromophores.
