Study of Vitellogenin Motif

open access: yes, 2020
Vitellogenin (VTG) is known to be a female-specific protein and a precursor form of egg yolk. Threevitellogenin,Vtg I,Vtg II and Vtg III have been identified in chicken.Vitellinogen precursors supply the major egg yolk proteins which are a source of nutrients during early development of egg-laying (oviparous) vertebrates and invertebrates.

Toxicity of Four Common Environmental Chemicals Across Caenorhabditis elegans Life Stages Supporting the One Health Concept

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...

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 ...

Rice Stripe Virus Infection Facilitates the Reproductive Potential of Laodelphax striatellus

open access: yesAgronomy
The rice stripe virus (RSV) is transmitted by the small brown planthopper Laodelphax striatellus in a persistent and circulative–propagative manner. During the last few decades, RSV has caused serious disease outbreaks in rice fields in China.

Oestrogen, an evolutionary conserved regulator of T cell differentiation and immune tolerance in jawed vertebrates? [PDF]

open access: yes, 2018
In teleosts, as in mammals, the immune system is tightly regulated by sexual steroid hormones, such as oestrogens. We investigated the effects of 17β-oestradiol on the expression of several genes related to T cell development and resulting T cell ...

Developmental environment and age shape macronutrient allocation to eggs and ejaculates

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Environmental conditions during development can have lasting effects on reproductive investment, but the sex‐ and age‐specific nature of such effects remains poorly understood.

Functional validation of a white pupae minimal gene construct in Ceratitis capitata (Diptera: Tephritidae)

open access: yesInsect Science, EarlyView.
An intronless version of the white pupae (wp) gene was engineered to restore the wild type brown puparium color in white pupae phenotype mutants of the Mediterranean fruit fly, Ceratitis capitata. Functionality of the minimal gene version (mini‐wp) was verified in vivo, as one copy of mini‐wp successfully restored the wild type phenotype in homozygous ...

Supplementation of Pangasianodon hypophthalmus broodstock feed with katuk extract, turmeric powder, and vitamin C before mating resulted in higher fecundity and produced larvae and juveniles with better growth performance

open access: yesJournal of the World Aquaculture Society
Increased vitellogenin availability for deposition in oocytes can improve the success of embryonal growth and development and the quality of catfish larvae and juveniles produced. This study aimed to evaluate the effects of katuk extract, turmeric powder,
