Multimodal targets of (‐)‐α‐thujone mediating avoidance behavior of a stored‐products pest, Tribolium castaneum, in response to irritant stimuli

open access: yesPest Management Science, EarlyView.
We identified four kinds of target molecules against (‐)‐α‐thujone associating avoidance behavior in Tribolium castaneum, indicating multimodality. Abstract BACKGROUND The reciprocal evolutionary processes among phytophagous insects and host plants involve host shift in the herbivorous insects in response to defense chemicals, such as plant‐derived ...

Oocyte activation: The impact of calcium signals on fertilization [PDF]

open access: yes, 2008
Fertilization is triggered by changes in intracellular calcium concentration. In mammals, these transients in ooplasmic calcium concentration take the form of repetitive spikes, so called calcium oscillations (Ca2+-oscillations).

Aberrant activation of chromosome asynapsis checkpoint triggers oocyte elimination [PDF]

open access: yes
Chromosome synapsis is an evolutionarily conserved process essential for meiotic recombination. HORMAD1 and HORMAD2, which monitor chromosome asynapsis by localizing to unsynapsed chromosome axes, are removed from synapsed chromosome axes by TRIP13 ...

Case series: Kikuchi‐Fujimoto disease with diagnostic overlap

open access: yesRheumatology &Autoimmunity, EarlyView.
Kikuchi‐Fujimoto disease (KFD) is a rare, self‐limiting necrotizing lymphadenitis that poses significant diagnostic challenges due to its overlap with tuberculosis, systemic lupus erythematosus (SLE), and malignancy. We present four cases highlighting distinct diagnostic complexities: KFD mimicking tuberculosis with concomitant latent TB infection and ...

Endometriosis disrupts oocyte metabolism and cortical granule function, impairing fertilization

open access: yesReproductive Biology and Endocrinology
Background Endometriosis is a chronic inflammatory disease strongly associated with reduced oocyte quality and subfertility, yet the underlying cytoplasmic defects remain poorly understood.

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...
