Pigments Induced by Organomercurial Compounds in Cephalosporium diospyri [PDF]

Journal of General Microbiology, 1974
Summary: The major pigments induced by parahydroxymercuribenzoate and parachloromercuribenzoate (both SH group inhibitors) in the fungus Cephalosporium diospyri have been characterized as carotenoids. Those present in both chemically-induced and light-induced cells include phytoene, β-carotene, γ-carotene, lycopene, torulene and neurosporaxanthin.

A Focus on Consumer Understanding of Food Safety and on the Role of the Social Media

Journal of Food Quality, Volume 2026, Issue 1, 2026.
This research examines how consumers perceive food safety, particularly emphasizing how social media are associated with perceptions and behaviors. An online cross‐sectional survey was conducted with a sample of Italian participants (n = 505), evaluating, among others, sociodemographic factors, the frequency, and trust in social media usage.

5,7‐Membered Cyclometallated Gold(III) Complexes with Pyridine‐Phenyl‐Oxazoline N^C^N Ligands as Catalysts for Organic Transformation Reactions Under Silver‐Free Conditions

Advanced Synthesis &Catalysis, Volume 367, Issue 17, September 26, 2025.
A series of 5,7‐membered cyclometallated gold(III) complexes with N^C^N tridentate ligands are prepared via transmetalation of pyridine‐phenyl‐oxazoline ligand‐containing organomercury compounds with potassium gold(III) chloride (KAuCl4) for catalysis.

Covalently Mercurated 6‐Phenylcarbazole Residues Promote Hybridization of Triplex‐Forming Oligonucleotides

ChemBioChem, Volume 26, Issue 8, April 14, 2025.
Organomercury derivatives of 6‐phenylcarbazole can stabilize triple helices when placed at the termini of triplex‐forming homothymine oligonucleotides. In some cases, this stabilization could be attributed to direct coordination of a Hg(II) ion to adenine‐N7 or cytosine‐N4.

Food Safety in Developing Countries: Common Foodborne and Waterborne Illnesses, Regulations, Organizational Structure, and Challenges of Food Safety in the Context of Nepal

Food Frontiers, Volume 6, Issue 1, Page 86-123, January 2025.
Food safety presents a global challenge, contributing to 600 million cases of foodborne diseases and 420,000 fatalities annually worldwide. A multisectoral One Health approach involving collaboration among government agencies, food industry stakeholders, consumers, and civil society organizations is imperative to enhance food safety in developing ...

Investigating the Effect of UV Irradiation and TiO2 Addition on Heavy Metal Adsorption by Inverse Vulcanized Sulfur Polymers

Chemistry – A European Journal, Volume 30, Issue 71, December 18, 2024.
The influence of light exposure on the process of mercury adsorption was explored in this study. Our findings reveal that exposure to UV−A wavelengths (315 nm–400 nm), in combination with the addition of titanium dioxide (TiO2), enhances the adsorption capacity of a sulfur‐rich polymer.

Triplet State‐Promoted Kumada‐Corriu Coupling Catalyzed by Hydrotris(3,5‐diisopropylpyrazolyl)boratocobalt(III)diiodide

European Journal of Inorganic Chemistry, Volume 27, Issue 34, December 2, 2024.
The light‐sensitive Kumada‐Corriu C−C hetero‐coupling of halogeno‐arenes and an arylmagnesiumbromides promoted by TpiPrCoI2, occurs with yields>80 % thanks to a singlet‐to‐triplet spin state d‐d transitions at bisaryl‐cobalt catalytic intermediates. Abstract The Kumada‐Corriu hetero‐coupling between an halogeno‐arene and an arylmagnesiumbromide can be ...

Henkel‐like Decarboxylation Produces Mononuclear Arylalkalis, [4‐(CH3)3N(C6H4)M]+ which Hydrolyse and Undergo Surprising SN2 Reactions Between Alkali Hydroxides and (CH3)3NC6H5+

European Journal of Inorganic Chemistry, Volume 27, Issue 31, November 4, 2024.
Mass‐spectrometry based metal‐mediated decarboxylation reactions continue to be a wellspring to form and study the reactions of organometallics. Here the mononuclear arylalkali cations [4‐(CH3)3N(C6H4)M]+ have been prepared and their hydrolysis reactions studied.

Protective Effects of Syringic Acid Against Oxidative Damage, Apoptosis, Autophagy, Inflammation, Testicular Histopathologic Disorders, and Impaired Sperm Quality in the Testicular Tissue of Rats Induced by Mercuric Chloride

Environmental Toxicology, Volume 39, Issue 10, Page 4803-4814, October 2024.
ABSTRACT Mercury (Hg) is one of the most toxic heavy metals that damage testicular tissue. Mercury chloride (HgCl2) is one of the most toxic forms of mercury that can easily cross biological membranes. Syringic acid (SA) is a natural flavonoid found in many vegetables and fruits.
