Hybridization of Aminoadamantanes with Cinnamic Acid Analogues and Elucidation of Their Antioxidant Profile

Journal of Chemistry, 2022
A series of seventeen cinnamic acid hybrids (4ai–ci) were obtained through an amidation of aminoadamantanes (amantadine, rimantadine, and memantine) with mixed anhydride generated from different substituted cinnamic acid and ethyl chloroformate.

Short-term starvation activates AMPK and restores mitochondrial inorganic polyphosphate, but fails to reverse associated neuronal senescence. [PDF]

Aging Cell
In this manuscript, Tagliafico et al. address the relationship between the levels of inorganic polyphosphate (polyP) and the onset of neuronal senescence. Moreover, they show that short‐term starvation restores depleted levels of polyP and activates AMPK; however, this is not sufficient to reverse the increased senescence associated to decreased polyP.

Osmoxylon-like fossils from early Eocene South America: West Gondwana-Malesia connections in Araliaceae. [PDF]

Am J Bot
Abstract Premise Araliaceae comprise a moderately diverse, predominantly tropical angiosperm family with a limited fossil record. Gondwanan history of Araliaceae is hypothesized in the literature, but no fossils have previously been reported from the former supercontinent.

Fossil insect-feeding traces indicate unrecognized evolutionary history and biodiversity on Australia's iconic Eucalyptus. [PDF]

New Phytol
Summary Fossilized plant–insect herbivore associations provide fundamental information about the assembly of terrestrial communities through geologic time. However, fossil evidence of associations originating in deep time and persisting to the modern day is scarce. We studied the insect herbivore damage found on 284 Eucalyptus frenguelliana leaves from

‘For Few Mean Ill in Vaine’: Roxolana and the Clash of Passion and Politics in the Ottoman Court in Fulke Greville's The Tragedy of Mustapha (1609) and Roger Boyle's The Tragedy of Mustapha (1665)

Renaissance Studies, Volume 37, Issue 5, Page 701-718, November 2023., 2023
Abstract Despite the many historical references to wealth, military strength and political efficiency, Turks were generally represented as violent, lustful and despotic figures in early modern cultural discourses. The stereotyped cultural Turk soon populated the London stages, thus moulding a recognisable dramatic type whose brutality and sexual ...

The first Gondwanan Euphorbiaceae fossils reset the biogeographic history of the Macaranga‐Mallotus clade

American Journal of Botany, Volume 110, Issue 5, May 2023., 2023
Abstract Premise The spurge family Euphorbiaceae is prominent in tropical rainforests worldwide, particularly in Asia. There is little consensus on the biogeographic origins of the family or its principal lineages. No confirmed spurge macrofossils have come from Gondwana.

The impact of obesity and adipokines on breast and gynecologic malignancies

Annals of the New York Academy of Sciences, Volume 1518, Issue 1, Page 131-150, December 2022., 2022
There is evidence for a link between obesity and breast, ovarian, and endometrial cancers. Fat‐secreted cytokines, known as adipokines, impact carcinogenesis and tumor progression. Understanding adipokine activated signaling in cancer may provide insight into new treatments, biomarkers, and disease progression.

Intermittent fasting in the prevention and treatment of cancer

CA: A Cancer Journal for Clinicians, Volume 71, Issue 6, Page 527-546, November/December 2021., 2021
Abstract Chronic caloric restriction (CR) has powerful anticarcinogenic actions in both preclinical and clinical studies but may be difficult to sustain. As an alternative to CR, there has been growing interest in intermittent fasting (IF) in both the scientific and lay community as a result of promising study results, mainly in experimental animal ...
