Water-Soluble Mn(III)-Porphyrins with High Relaxivity and Photosensitization.

Three water-soluble Mn(III)-porphyrin complexes with cationic pyridyl side groups bearing COOH- or OH-terminated carbon chains in the meta or para positions have been synthesized as probes for both magnetic resonance imaging (MRI) and photodynamic therapy (PDT). The complexes , , and are highly water-soluble, and their relaxivities range between 10 and 15 mM s, at 20-80 MHz and 298 K, 2-3 times higher than that of commercial Gd(III)-based agents. The complexes containing carboxylate () or alcoholic () side chains in the para position are endowed with higher relaxivities and have also shown efficient photoinduced DNA cleavage and singlet oxygen (O) generation.

Open mesh repair of an iatrogenic post-nephrectomy Bochdalek hernia in an adult: a case study.

Bochdalek hernias arise from a developmental failure of the pleuroperitoneal canal to close, allowing abdominal contents to herniate into the thorax and compress the developing lung parenchyma. In rare cases, Bochdalek hernias may arise in adults and usually present with symptoms related to the hernia. Treatment consists of either open, laparoscopic, or robotic repair to close the defect.

Diagnostic challenges arose as symptoms mimicked other diseases.

Microbiological hazards associated with the use of water in the post-harvest handling and processing operations of fresh and frozen fruits, vegetables and herbs (ffFVH). Part 5 (Frozen FVH process water management plan).

Water used in post-harvest handling and processing operations is an important risk factor for microbiological cross-contamination of fruits, vegetables and herbs (FVH).

Intervention strategies were limited to the use of water disinfection treatments such as peroxyacetic acid and hydrogen peroxide.

Microbiological hazards associated with the use of water in the post-harvest handling and processing operations of fresh and frozen fruits, vegetables and herbs (ffFVH). Part 2 - A dynamic mass balance model for handling and processing operations in ffFVH using water.

A dynamic mass balance model was developed to simulate contamination dynamics in the process water of fresh and frozen fruits, vegetables and herbs (ffFVH) during processing and handling operations. The mass balance relates to the flux of water and product in a wash tank and the number of microbial cells released in the water, inactivated by the water disinfectant or transferred from the water back to the product. Critical variables describing microbial dynamics in water are: (i) the chemical oxygen demand (COD), as an indicator of the concentration of organic matter; (ii) free chlorine (FC) and particularly its antimicrobial fraction, hypochlorous acid (HOCl); and (iii) the microbial population levels.

First record of Serban, 2000 (Bathynellacea, Bathynellidae) from subterranean waters of South Korea, with the description of a new species.

This study describes , the first new species of Bathynellidae family reported in East Asia since 2000, and it presents the first molecular analysis using CO1 and 18S gene sequences. Morphological analysis reveals that the new species and previously known species uniquely share key characteristics in the male and female thoracopods VIII. However, the presence or absence of the median seta on the antenna exopod, along with the length differences between the four spines in the furca, distinguish the new species from , 2000.

Pyridinamide Ion Pairs: Design Principles for Super-Nucleophiles in Apolar Organic Solvents.

A comprehensive analytical protocol combining conductivity, diffusion-ordered NMR (DOSY), and photometric kinetic measurements is employed to analyze the nucleophilic reactivity of pyridinamide ion pairs in low-polarity organic solvents. The association patterns of these systems are found to strongly depend on cation size, with larger cations favoring the formation of cationic triple ion sandwich complexes together with free and highly nucleophilic anions. Kinetic studies using the ionic strength-controlled benzhydrylium method demonstrate that pyridinamide ions exhibit significantly higher nucleophilicities as compared to established organocatalysts, particularly in low-polarity solvents.

Projected Wave Function Extrapolation Scheme to Accelerate Plane-Wave Hybrid Functional-Based Born-Oppenheimer Molecular Dynamics Simulations.

Born-Oppenheimer molecular dynamics (BOMD) simulations are of great interest for the dynamic properties of molecular and solid systems. However, BOMD simulations necessitate not only an extensive period of dynamical evolution but also costly self-consistent-field (SCF) electronic structure calculations, especially for hybrid functional-based BOMD (H-BOMD) simulations within plane-wave basis sets. Here, we propose an improved always stable predictor-corrector (ASPC) method for the wave function extrapolation to accelerate the plane-wave H-BOMD simulations, named projected ASPC (PASPC), yielding a wave function closer to the actual solution space and efficiently reducing the number of SCF iterations at each MD step.

Methyltrimethoxysilane (MTMS).

Methyltrimethoxysilane (MTMS) has been used as a coupling agent in thermoplastics and thermosetting resins, a cross-linker in silicone sealants, a water repellent component, and in silicone hard-coats for plastics. Acute studies in experimental animals showed a low order of toxicity for MTMS via oral, dermal, and inhalation routes. MTMS was slightly irritating to both eyes and skin in rabbits.
