High Pressure Stabilizes the Elusive Hexacoordinated Carbon

ChemistryEurope, EarlyView.
The MCF6 species (M = Ca, Sr) is more stable than the bicomponent MF2…CF4 mixture in the solid‐state at high pressure (p > 400 GPa). The main building block is the [CF6]2− unit in which carbon is hexacoordinated. Unusually high coordination number for elements has been of great interest in chemistry.

Human papillomavirus detection and p16 methylation pattern in a case of esophageal papilloma

Brazilian Journal of Medical and Biological Research, 2010
Esophageal cancer is a prevalent cancer worldwide. Some studies have reported the possible etiology of human papillomavirus (HPV) in benign and malignant papillomas of the esophagus but the conclusions are controversial.

Multiple Dimerization Modes in Thiocarboxylate Paddlewheel Complexes: A Comprehensive View of Energy Landscapes from DFT Calculations and Statistics

Chemistry – A European Journal, EarlyView.
Staggered, square, and heavily bent dimers occur in the five known solvatomorphs of paddlewheel (PW) complex [PtVO(SOCPh)4]. These and other structural motifs are well within energetic reach due to the shallow potential energy surface that guides dimerization and are included in a revised classification of available structural data on heterobimetallic ...

Catalytic Amyloids: Turning Fibrils Into Biocatalysts

Chemistry – A European Journal, EarlyView.
Amyloids, traditionally associated with diseases, have emerged as versatile catalytic scaffolds. From natural amyloid sequences to bioinspired and de novo designs, we highlight strategies to construct catalytic active sites and anchor enzymes onto fibrils, creating versatile nanomaterials with tunable activities. ABSTRACT Amyloids have been regarded as

Silent Partners in the Mill: Unveiling the Role of Additives in Mechanochemical Synthesis

Chemistry – A European Journal, EarlyView.
Mechanochemistry offers a sustainable, solvent‐free alternative to traditional synthesis, often enhanced by additives in a process known as additive‐assisted grinding. This review discusses how various additives, including liquids, ionic solids, and advanced materials like ionic liquids and piezoelectric compounds, improve reaction efficiency ...

Discrimination of Two Species of Orangutans (Pongo SP.): a Rapid Protocol for Rehabilitation Centres and Zoos [PDF]

, 2009
Currently orangutans exist in increasingly fragmented and isolated populations. While Sumatran orangutan is primarily found in northern Sumatra, the Bornean is distributed in Central, West, and East Kalimantan, Sarawak and Sabah.

Pathogenesis and potential therapeutic targets of trichorhinophalangeal syndrome; lessons obtained from animal studies

Developmental Dynamics, EarlyView.
Abstract Trichorhinophalangeal syndrome (TRPS) is a rare genetic disease inherited in an autosomal dominant manner. It occurs in 1 in 100,000 people globally and is caused by several types of mutations of the TRPS1 gene. Since the first human patient was reported in 1966, typical and atypical pathologies, disease courses, and treatment case ...

Polymorphism in the internal transcribed spacer (ITS) of the ribosomal DNA of 26 isolates of ectomycorrhizal fungi. [PDF]

, 2018
Inter- and intraspecific variation among 26 isolates of ectomycorrhizal fungi belonging to 8 genera and 19 species were evaluated by analysis of the internal transcribed sequence (ITS) of the rDNA region using restriction fragment length polymorphism ...

Epigenotoxicity: Decoding the epigenetic imprints of genotoxic agents and their implications for regulatory genetic toxicology

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Regulatory genetic toxicology focuses on DNA damage and subsequent gene mutations. However, genotoxic agents can also affect epigenetic marks, and incorporation of epigenetic data into the regulatory framework may thus enhance the accuracy of risk assessment.
