Evaluation of the theoretical risk of cross-reactivity among recently identified food allergens for dogs. [PDF]

Vet Dermatol, 2022
Background: There is increasing evidence of cross‐reactivity between allergens of close or distant species. The A‐RISC (Allergens'–Relative Identity, Similarity and Cross‐reactivity) index helps evaluate the risk of theoretical cross‐reactivity between proteins of the same family among different species.

Low‐Valent Metals in Metal‐Organic Frameworks Via Post‐Synthetic Modification

Angewandte Chemie, Volume 135, Issue 49, December 4, 2023., 2023
Matrix isolation of low‐valent complexes within metal–organic frameworks (MOFs) facilitates exceptional gas‐phase catalytic activity, stabilization of solution‐inaccessible catalysts, and fundamental insight into pertinent reaction mechanisms. MOFs present an ideal porous, crystalline, and chemically mutable matrix for such species.

Switchable Metal Sites in Metal–Organic Framework MFM‐300(Sc): Lewis Acid Catalysis Driven by Metal–Hemilabile Linker Bond Dynamics

Angewandte Chemie, Volume 134, Issue 48, November 25, 2022., 2022
An unconventional catalytic activity was demonstrated for the Strecker reaction using a saturated ScIII‐based MOF known as MFM‐300(Sc). This activity was possible due to metal‐hemilabile linker bond to create an intermittent free ScIII site. Abstract Uncommon reversible guest‐induced metal‐hemilabile linker bond dynamics in MOF MFM‐300(Sc) was ...

Achieving Sub-ppm Sensitivity in SO₂ Detection with a Chemically Stable Covalent Organic Framework. [PDF]

Angew Chem Int Ed Engl
This study introduces the first experimental exploration of COFs for SO2 detection. The imine‐functionalized COF exhibited reversible SO2 sorption with over 50 cycles of reversibility. The isosteric enthalpy of adsorption was measured at −42.3 kJ/mol, reflecting a strong SO2‐COF interaction. Molecular dynamics and Møller–Plesset calculations elucidated

Fluorescent Sensing of SO₂ by MFM-300(M) Metal-Organic Frameworks: Influence of Semi-Open Metal Centres. [PDF]

Small
The MFM‐300(M) series is investigated as a fluorescent platform for SO2 detection, highlighting how the nature of metal centers modulates fluorescence emission. MFM‐300(Al) displays the brightest emission and strongest response. Experimental and computational studies reveal distinct quenching mechanisms depending on the metal center, highlighting the ...

Childhood maltreatment history and trauma‐specific predictors of parenting stress in new fathers

Infant Mental Health Journal: Infancy and Early Childhood, Volume 44, Issue 6, Page 767-780, November 2023., 2023
Abstract For new fathers, parenting stress is a risk factor for impaired early parenting and child maltreatment perpetration. Predictors of parenting stress, including fathers’ own experiences of trauma, could be useful intervention targets to support new fathers.

Immunoglobulin E‐specific allergens against leaf in serum of dogs with clinical features of grass leaf allergy

Veterinary Dermatology, Volume 34, Issue 5, Page 393-403, October 2023., 2023
Background – Grass leaf has been suspected to cause immunoglobulin (Ig)E‐mediated immediate hypersensitivity reactions both in humans and in dogs. However, most studies in this area are case control studies without in vitro data showing the involvement of IgE in the reaction.

Lewis Acid‐Catalyzed Ring‐Opening Alcoholysis of Cyclohexene Oxide: The Role of Open Metal Sites in the Bi(III)‐based Metal‐Organic Framework SU‐101

ChemCatChem, Volume 15, Issue 13, July 7, 2023., 2023
Cyclohexene oxide alcoholysis: SU‐101 was applied for the Lewis acid‐catalyzed ring‐opening alcoholysis of cyclohexene oxide. Abstract SU‐101 was screened for the acid‐catalyzed ring‐opening alcoholysis of cyclohexene oxide. Results indicated access to open metal sites within SU‐101, a fundamental requirement (Lewis acid Bi+3 sites) for this reaction ...

Effects of trauma‐focused rumination among trauma‐exposed individuals with and without posttraumatic stress disorder: An experiment

Journal of Traumatic Stress, Volume 36, Issue 2, Page 285-298, April 2023., 2023
Abstract Rumination, or thinking repetitively about one's distress, is a risk factor for posttraumatic stress disorder (PTSD). Current theories suggest that rumination contributes to PTSD symptoms directly, by increasing negative reactions to trauma cues (i.e., symptom exacerbation), or represents a form of cognitive avoidance, if verbal ruminations ...

Associations among psychosis, mood, anxiety, and posttraumatic stress symptoms: A network analysis

Journal of Traumatic Stress, Volume 36, Issue 2, Page 385-396, April 2023., 2023
Abstract The associations among psychotic experiences (i.e., hallucinations and delusions), trauma exposure, and posttraumatic stress symptoms are complex and multidirectional. Using network analysis to understand how psychotic experiences and symptoms of posttraumatic stress disorder (PTSD) relate to one another may identify new interventional targets
