The CYP6P4 I236M Mutation Imposes High Fitness Costs and Increases Susceptibility to Chlorfenapyr-Based Insecticide-Treated Nets in Anopheles gambiae

This study demonstrates that while the CYP6P4-I236M mutation in *Anopheles gambiae* confers strong resistance to pyrethroid and PBO-based nets, it imposes significant fitness costs and reduced efficacy against chlorfenapyr-based nets, suggesting that rotation or mixture strategies with chlorfenapyr could effectively manage resistance.

The bigfin reef squid (Sepioteuthis lessoniana Férussac, 1831) species complex in the Mediterranean Sea: genetic evidence for multiple Red Sea lineages in a Lessepsian migrant

This study reveals that the bigfin reef squid in the Mediterranean Sea comprises at least two distinct cryptic lineages of Red Sea origin, challenging the traditional view of *Sepioteuthis lessoniana* as a single species and highlighting the complexity of Lessepsian invasions.

Diversity, Nesting Ecology and Worker-level Morphometric Structure of Stingless Bees (Hymenoptera: Apidae: Meliponini) in the Bimodal Forest Zone of Central Cameroon

This study documents the diversity, nesting ecology, and worker-level morphometric structure of stingless bees in Central Cameroon's bimodal forest zone, revealing that *Hypotrigona gribodoi* and *Dactylurina staudingeri* exhibit contrasting, size-structured phenotypic variations and distinct nesting habits while establishing the first locality-resolved baseline to support conservation and meliponiculture.

Adenyl cyclase 6 is an evolutionary conserved chief regulator of peripheral nerve development and timely myelination in vertebrates

This study identifies adenylate cyclase 6 (Adcy6) as an evolutionarily conserved, essential regulator within both Schwann cells and neurons that drives timely peripheral nerve development, myelination, and ion channel clustering through cAMP signaling in vertebrates.

A Novel AR Splice-Site Variant Causing Complete Androgen Insensitivity Syndrome: Transcript Confirmation and Lessons for Splice Prediction

This study reports a novel AR c.2319-1G>T variant causing complete androgen insensitivity syndrome via exon 6 skipping, confirming through transcript analysis that canonical splice-site disruptions strongly correlate with this severe phenotype while highlighting limitations in relying solely on in silico prediction tools for non-substitution variants.

Comparative Molecular Docking of Roscovitine, Nutlin-3, and Pifithrin-α at the CDK2 ATP-Binding Pocket: Interaction Profiling and Implications for p53 Pathway Modulation

This study utilizes molecular docking simulations to demonstrate that while Roscovitine and Pifithrin-α exhibit strong predicted binding affinities to the CDK2 ATP-pocket with distinct interaction profiles, Nutlin-3 shows significantly weaker binding, suggesting Pifithrin-α warrants further investigation as a potential off-target binder within the p53 signaling pathway.

Residual Body-Mass Dependence in VO₂peak Normalization: Comparison of Ratio Scaling, Allometric Modeling, and Regression–Residual Methods

This study demonstrates that while conventional ratio scaling of peak oxygen uptake (VO₂peak) retains significant residual dependence on body mass, regression–residual normalization effectively eliminates this bias, offering a superior alternative to both ratio scaling and conventional allometric modeling for adjusting aerobic capacity across diverse body sizes.
