Exploring the Antiparasitic Activity of the Sea Cucumber Isostichopus sp. aff. badionotus From the Northern Coast of Colombia Against Trypanosoma cruzi

The Scientific World Journal
Chagas disease, caused by Trypanosoma cruzi, remains a neglected tropical infection with limited therapeutic options. Sea cucumbers are recognized as rich sources of bioactive sulfated metabolites with potential antiparasitic properties; however ...

Mechanochemical Synthesis of Lead-Free Halide Layered Double Perovskites: A Green and Scalable Approach. [PDF]

ChemSusChem
Herein we report a facile, green, and scalable synthetic alternative for the obtention of layered double perovskites (LDPs) via mechanosynthesis. This approach allows for the synthesis of phase‐pure LDPs in batches of up to 5 g within minutes. To our knowledge, this represents the largest scale and fastest synthesis of these materials reported to date.

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.

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 ...

Reactividad puzolánica de arcillas caoliníticasuna revisión [PDF]

Revista ingeniería de construcción, 2017
Pozzolans have demonstrated to be highly efficient mineral additions in the concrete industry, because they reduce the environmental impact generated by the cement manufacture, improve the physical, chemical and mechanical properties of blends, and reduce costs.

Reactividad cutánea en conjuntivitis alérgica

Revista Alergia México, 2018
Background: Allergic conjunctivitis is caused by an IgE-mediated mechanism or immediate hypersensitivity due to allergen direct contact on the conjunctival surface of sensitized patients, which elicits mastocyte activation and inflammatory mediators’ release.
