Laparoscopic ovum pick up in common marmoset (Callithrix jacchus)

Theriogenology Wild
Ovum pick up (OPU) is a crucial assisted reproductive technique for transgenic research of non-human primates, and has commonly been performed via laparotomy in common marmosets (Callithrix jacchus).

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, EarlyView.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

EFFECT OF CYSTEAMINE ON THE RATE OF IN VITRO MATURATION OF OOCYTES IN TWO MEDIA [PDF]

Acta Medica Iranica, 2006
Rate of in vitro maturation of oocytes is one of the challenges of assisted reproductive techniques. In this study we investigated the effects of supplementation of cysteamine on the rate of in vitro maturation of oocytes in two different media. Germinal

Effect of single versus grouped culture of human cumulus–oocyte complexes in PCOS women treated with biphasic in vitro maturation: A sibling oocyte pilot study

Reproductive Medicine and Biology
Purpose This study investigated the differences in the maturation rate of single versus grouped cumulus–oocyte complexes (COCs) culture methods for capacitation in vitro maturation (CAPA‐IVM) in women with polycystic ovary syndrome (PCOS).

Imeglimin attenuates liver fibrosis by inhibiting vesicular ATP release from hepatic stellate cells

FEBS Letters, EarlyView.
Imeglimin, at clinically relevant concentrations, inhibits vesicular ATP accumulation and release from hepatic stellate cells, thereby attenuating purinergic signaling and reducing fibrogenic activation. This mechanism reveals a newly identified antifibrotic action of imeglimin beyond glycemic control.

Ovarian morphometric characterization and in vitro maturation of oocytes obtained from buffalo (Bubalus bubalis) ovaries – partial results

Italian Journal of Animal Science, 2010
Buffalo ovaries were collected from a slaughterhouse (Frigol, Brazil) and transported to the laboratory in saline solution at 36º C. The ovaries were dissected to realize the evaluations (weight, length, width and height of the ovary; corpus luteum ...

Human TIMP1 Is a Growth Factor That Improves Oocyte Developmental Competence

BioTech, 2023
Oocyte developmental competence is the ability of a mature oocyte to be fertilized and subsequently support embryonic development. Such competence is gained during folliculogenesis and is facilitated by the bidirectional communication into a compacted ...

Iron Overload-Induced Ferroptosis Impairs Porcine Oocyte Maturation and Subsequent Embryonic Developmental Competence in vitro

Frontiers in Cell and Developmental Biology, 2021
Accumulating evidence indicates that ferroptosis is an iron-dependent form of regulated cell death. This type of iron-dependent programmed cell death is different from traditional forms of regulated cell death, such as apoptosis and autophagy.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target

FEBS Letters, EarlyView.
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.
