Heterotopic Triplet Pregnancy After Assisted Reproductive Techniques: A Systematic Review.
Cureus
December 2024
Department of Obstetrics and Gynecology, School of Health Sciences, University of Patras, Patras, GRC.
Heterotopic pregnancy is defined as the simultaneous presence of an intrauterine and an extrauterine pregnancy and is considered a rare condition. As a part of this entity, heterotopic triplet pregnancy, defined as the presence of three embryos, with at least one being ectopic, is exceedingly rare. In recent years, the broad use of assisted reproductive techniques to help infertile couples has contributed to the constant rise of non-spontaneous heterotopic triplets.

Hypercalcemia of malignancy (HCM) is the most common cause of hypercalcemia in hospitalized patients. The pathogenesis of HCM is often multifactorial. One of the rare causes of HCM is extra-renal production of 1,25-dihydroxyvitamin D (or calcitriol), which is often seen in patients with lymphoproliferative malignancies.

While previous work has shown that signaling gradients diversify progenitor fates at the dorsal and ventral ends of the tissue, the basis of fate specification in intermediate regions has remained unclear. Here we use zebrafish to investigate the neural plate, which precedes neural tube formation, and show that its pre-patterning by a distinct signaling environment enables intermediate fate specification.

However, it remains unclear how these cell types interact with one another and how synovial microenvironments shape observed cell states. Here, we use spatial transcriptomics (ST) to define stable microenvironments across eight synovial tissue samples from six RA patients and characterize the cellular composition of ectopic lymphoid structures (ELS).

Lactate dehydrogenase A (LDHA) is upregulated in multiple cancer types and contributes to the Warburg effect. Several studies have found that many tumor-related genes have subtypes and play important roles in promoting cancer development. Here, we identified a novel LDHA transcript, which produced a new protein 3 kDa larger than LDHA, which we named LDHAα.
