The scaling of seed‐dispersal specialization in interaction networks across levels of organization

open access: yesEcography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Environmental and geomorphological drivers of frog diversity on islands worldwide

open access: yesEcography, EarlyView.
Island biogeography models primarily rely on island physical features and isolation to explain their biodiversity patterns. While newer models have incorporated functional traits to understand plant distribution, few empirical studies have tried to disentangle geometric constraints from niche‐based processes to predict multiple diversity facets of ...

Bicarbonate is required for migration of sperm epididymal protein DE/CRISP-1 to the equatorial segment and expression of rat sperm fusion ability [PDF]

open access: yes, 2004
Numerous studies have demonstrated that sperm capacitation is a bicarbonate-dependent process. In the rat, capacitation has not been studied as much as in other species, mainly because of the difficulties in carrying out functional assays with this ...

Stereochemical Modulation of Palladacyclopentadienyl Complexes Bearing Diphosphine Ligands: A Key to Enhanced DNA Interaction and Anticancer Activity

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A modular library of structurally robust palladacyclopentadienyl Pd(II) complexes bearing achiral and chiral diphosphines was developed, revealing a strong influence of diphosphine design and ligand chirality on cytotoxicity and selectivity against ovarian cancer cells, including platinum‐resistant models.

Mutation type‐specific transcriptomic signatures and readthrough therapy rescue in SMC1A‐related developmental and epileptic encephalopathy

open access: yesEpilepsia, EarlyView.
Abstract Objective This study was undertaken to investigate the molecular consequences of pathogenic variants in the SMC1A gene—particularly those associated with developmental and epileptic encephalopathy (DEE85)—and to evaluate the therapeutic potential of ataluren in restoring SMC1A function and mitigating disease‐related transcriptomic and genomic ...

Carbonic anhydrase inhibitor acetazolamide shifts synaptic vesicle recycling to a fast mode at the mouse neuromuscular junction [PDF]

open access: yes, 2017
Acetazolamide (AZ), a molecule frequently used to treat different neurological syndromes, is an inhibitor of the carbonic anhydrase (CA), an enzyme that regulates pH inside and outside cells.

Peripheral and central mechanisms involved in hormonal control of male and female reproduction [PDF]

open access: yes, 2016
Reproduction involves the integration of hormonal signals acting across multiple systems togenerate a synchronized physiological output. A critical component of reproduction is the luteinizinghormone (LH) surge, which is mediated by estradiol (E2) and ...

ULK4 and CDKN2A polymorphisms influence the risk of developing monoclonal gammopathy of undetermined significance

open access: yesInternational Journal of Cancer, EarlyView.
What's New? Monoclonal gammopathy of undetermined significance (MGUS) is an asymptomatic precursor to multiple myeloma, sharing substantial genetic features with overt malignancy. Given evidence implicating autophagy in myeloma risk, this study examined whether genetic variations in autophagy‐related genes influence MGUS susceptibility.
