Knockdown of Sec16 causes early lethality and defective deposition of the protein Rp30 in the eggshell of the vector Rhodnius prolixus

open access: yesFrontiers in Cell and Developmental Biology
In nearly every species of insect, embryonic development takes place outside of the mother’s body and is entirely dependent on the elements that the mother had previously stored within the eggs.

Autophagy Determines Distinct Cell Fates in Human Amnion and Chorion Cells

open access: yesAutophagy Reports
Human fetal membranes (amniochorion) that line the intrauterine cavity consist of two distinct cell layers; single-layer amnion epithelial cells (AEC) and multilayer chorion trophoblast cells (CTC).

Previable PROM in twins: A systematic review and meta‐analysis

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Previable prelabor rupture of membranes (PROM) in twin pregnancies is a rare but high‐risk condition associated with substantial neonatal mortality and maternal morbidity. Management options include expectant management and selective reduction, though guidance is limited and based primarily on singleton data.

Synergistic effects of antimicrobial components of the human-derived composite amnion-chorion membrane on bacterial growth

open access: yesFrontiers in Cellular and Infection Microbiology
IntroductionThe human-derived amnion-chorion membrane (ACM) has endogenous antimicrobial properties, which are important for preventing the colonization and survival of oral bacteria on exposed membranes.

Effects of shear on eggs and larvae of striped bass, morone saxatilis, and white perch, M. americana [PDF]

open access: yes, 1976
Shear stress, generated by water movement, can kill fish eggs and larvae by causing rotation or deformation. Through the use of an experimental apparatus, a series of shear (as dynes/cm2)-mortality equations for fixed time exposures were generated for ...

Luteal phase stimulation versus follicular phase stimulation in poor ovarian responders: A systematic review and a meta‐analysis

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Poor ovarian response (POR) complicates a substantial proportion of in vitro fertilization (IVF) cycles, frequently causing cycle cancellation and suboptimal reproductive outcomes. Conventional follicular‐phase ovarian stimulation (FPOS) protocols often yield limited results, prompting the evaluation of alternative strategies such ...

RISK FACTORS AND CYTOMORPHOLOGICAL CHARACTERISTICS OF THE CHORION IN THE GENESIS OF SPONTANEOUS ABORTION IN FIRST TRIMESTER

open access: yesАкушерство, гинекология и репродукция, 2016
Cytomorphological features of the chorion and risk factors for spontaneous abortion in the first trimester are studied. A total of 98 pregnant women were divided into 2 groups: the 1st (main) group - 38 pregnant women with spontaneous abortion in 1 ...

Timing of conception after methotrexate and subsequent pregnancy outcomes: A retrospective cohort study

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Methotrexate is widely used to treat ectopic pregnancy (EP). Concerns about its teratogenicity have led to uncertainty regarding the optimal interval before attempting conception. Guidelines recommend a 3‐month washout period, while the manufacturer advises 6 months. Evidence on the safety of early conception is limited.

Role of egg surface glycoconjugate in the fertilization of the rock shrimp Rhynchocinetes typus (Milne-Edwards, 1837) El rol de los glicoconjugados de las cubiertas ovocitarias en la fecundación del camarón de roca Rhynchocinetes typus (Milne-Edwards, 1837)

open access: yesLatin American Journal of Aquatic Research, 2012
During first gamete interaction, oligosaccharides on the glycoproteins present in oocyte envelopes of the rock shrimp, Rhynchocinetes typus, play an important role in spermatozoon recognition prior to the onset of penetration. These oligosaccharides have
