Clinical Insights From a Case of Sifrim‐Hitz‐Weiss Syndrome With a CHD4 Variant: Expanding the Phenotypic Spectrum and Its Response to Growth Hormone Therapy

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 6, Page 1403-1410, June 2026.
ABSTRACT To enhance clinicians' understanding of Sifrim‐Hitz‐Weiss syndrome (SIHIWES), this study investigated the clinical phenotypes, genetic characteristics, and response to growth hormone therapy in a patient. A case of a patient with global developmental delay and distinctive facial features is presented.

Early evolutionary history of the seed

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Colonization and spatiotemporal distribution of bruchid pests in lentil and faba bean fields

open access: yesPest Management Science, Volume 82, Issue 6, Page 5780-5794, June 2026.
This study of 104 fields identifies Bruchus signaticornis in lentils and B. rufimanus in faba beans as the sole grain‐damaging species. Their uniform distribution within fields and the strong effect of regulatory factors on larvae and egg survival emphasize the need for species‐specific, phenology‐based and spatially informed integrated pest management
