Comparative proteomic profiling reveals molecular characteristics associated with oogenesis and oocyte maturation during ovarian development of Bactrocera dorsalis (Hendel) [PDF]

open access: yes, 2017
Time-dependent expression of proteins in ovary is important to understand oogenesis in insects. Here, we profiled the proteomes of developing ovaries from Bactrocera dorsalis (Hendel) to obtain information about ovarian development with particular ...

Dehydrated human amnion/chorion membrane regulates stem cell activity in vitro

open access: yesJournal of Biomedical Materials Research. Part B - Applied biomaterials, 2015
Human‐derived placental tissues have been shown in randomized clinical trials to be effective for healing chronic wounds, and have also demonstrated the ability to recruit stem cells to the wound site in vitro and in vivo.

On–Off Switchable Micromotors for Use in Steerable Microvehicles

open access: yesAdvanced Robotics Research, EarlyView.
Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

The Lipid Phosphate Phosphatase Wunen Promotes Eggshell Formation and Is Essential for Fertility in Drosophila

open access: yesBiology, 2023
The eggshell that surrounds insect eggs acts as a barrier, protecting against biotic factors and desiccation. The eggshell is a multi-layered structure which is synthesised by the somatic follicle cells that surround the developing oocyte.

Bisphenol B Exposure Induces Miscarriage by Suppressing Migration/Invasion and Migrasome Formation

open access: yesAdvanced Science, EarlyView.
BPB (Bisphenol B) exposure up‐regulates ER (estrogen receptor) levels, enhances its interactions with the lnc‐HZ04 promoter region, and thus promotes ER‐mediated lnc‐HZ04 transcription. Subsequently, lnc‐HZ04 suppresses TCF4 (transcription factor 4)‐mediated PKCA (protein kinase C alpha) transcription and subsequently suppresses migration/invasion and ...

Insecticide Effects on Normal Development and Hatch of Embryos of \u3ci\u3eParatanytarsus Parthenogeneticus\u3c/i\u3e (Diptera: Chironomidae) [PDF]

open access: yes, 2017
Simple, low cost methods are needed to determine the effect of pesticides on non-target aquatic organisms. In this report, embryos of Paratanytarsus parthenogenetic us were exposed from deposition to hatch to five pesticides.

Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

open access: yesAdvanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

On-field Gross Morphology Evaluation of Dromedary Camel (Camelus dromedarius) Fetal Membranes

open access: yesAnimals
The dromedary camel (Camelus dromedarius) fetal membranes, commonly referred to as “the placenta”, are epitheliochorial, diffuse, and microcotyledonary, similarly to the mare’s placenta.

Features of the cytokine profile in the structures of chorion and placenta in premature termination of pregnancy

open access: yesPatologìâ, 2020
The placenta is a mirror of pregnancy. The formation of a healthy placenta predetermines embryo-endometrial relationships, which are regulated by cytokines.
