1,2‐Diazetidines − Structure, Synthesis, and Functionalization
European Journal of Organic Chemistry, EarlyView.1,2‐Diazetidines are saturated four‐membered heterocycles featuring two adjacent nitrogen atoms. Despite recent advances in their synthesis and promising potential in medicinal chemistry, the chemistry of these cyclic hydrazines remains underexplored.

Total Synthesis of Novel Oxylipins: Plasmodiophorols A, C, and Epimers
European Journal of Organic Chemistry, EarlyView.The first total syntheses of plasmodiophorols A and C, recently identified α‐linolenic acid‐derived oxylipins, were achieved from chiral cyclopentafuranone in 12–13 steps. The routes use enzymatic desymmetrization, epimerization, and diastereoselective Grignard addition, providing stereocontrolled access to the natural products and reliable standards ...

Divergent Synthesis of Polycyclic Derivatives via Gold Catalysis
European Journal of Organic Chemistry, EarlyView.Gold(I)‐catalyzed cycloisomerization enables the formation of complex 3D structures from simple enyne precursors. This study presents a divergent strategy to synthesize functionalized bicyclic and tricyclic scaffolds from a common alkynyl ketone.

Creativity and its link to epilepsy
Epilepsia Open, EarlyView.Abstract Creative thinking represents one of our highest‐order cognitive processes, involving multiple cortical structures and an intricate interplay between several cortical and subcortical networks. It results in novel ideas that translate to useful products or concepts. The evolutionary purpose of creativity is therefore apparent, as it advances our

Sonographic Diagnosis of an Intercostal Artery Pseudoaneurysm: A Case Report and Literature Review
Journal of Clinical Ultrasound, EarlyView.A 63‐year‐old male presented to the emergency department after being found unconscious during a welfare check. Following a prolonged three‐month hospital admission, the patient developed left flank pain. Spectral Doppler ultrasound revealed a large isoechoic lesion with layering echoes, and spectral Doppler demonstrated bidirectional flow.

Cycling: An Increasingly Untouched Source of Physical and Mental Health [PDF]
Cost savings associated with increased gasoline prices and lower levels of urban sprawl have been cited in terms of personal savings, environmental awareness, reduced costs through lower travel times and congestion, and reduced income inequality.

Journal of Quaternary Science, EarlyView.ABSTRACT The second half of the Allerød interstadial in the Netherlands is characterised by pine forest. Excavated trunks of 165 pine trees at Leusden‐Den Treek in the central Netherlands (LETR16) were dated by dendrochronology and radiocarbon. Two chronologically separated pine forest phases occurred during relatively warm periods as recorded in ...

Characteristics of Sensitive Scalp in French Women and Comparison With Scalp Dermatoses
JEADV Clinical Practice, EarlyView.ABSTRACT Background A sensitive scalp is a particular location of sensitive skin, characterised by the occurrence of unpleasant sensations which cannot be explained by a skin disease. It is a common syndrome that could affect 30%–50% of women. Clinical data are scarce, and the impact on the quality of life poorly described.
