The pinnipeds' placenta has been described as zonary, annular, labyrinthic and endotheliochorial, like that of the terrestrial carnivores. This article describes the placenta of Mirounga leonina, a phocid pinniped, focusing on some morphological features related to fetal nutrition.

Placental samples from three elephant seals were collected and conditioned after natural delivery at the Antarctic Specially Protected Area 132. Histological and ultrastructural studies were conducted; cytokeratins, vimentin, α-smooth muscle actin, and desmin proteins were detected using immunohistochemistry.

The placentas were zonary, lobed, belt-shaped, and showed multiple vivid orange areas, which corresponded to bilirubin crystalline pigment found among chorionic villi and inside trophoblast cells. In the labyrinth, cytotrophoblast cells were isolated and there was a scant syncytium interposed between maternal and fetal vessels. Fetal vessels were small, round, and frequently intratrophoblastic, while maternal vessels werome of them, as the notably large sinuous maternal capillaries and fetal capillary indentation into the syncytium, are shared, e.g., by Phocidae and Mustelidae. Besides hemotropic nutrition taking place through an extremely narrow barrier, the abundant necrotic material and hematic products might allow substantial endocytosis of detritus even in term placentas, in this species giving birth to precocious offspring.
Stomatin-like protein 2 (SLP2) is highly expressed in human first trimester trophoblast cells, but its functions in placental morpho-physiology remain unknown. This study aimed to determine the role of SLP2 in the proliferation and invasion of human first trimester trophoblast cells.

Immunofluorescence was used to determine the expression and localization of SLP2 in normal and miscarriage human first trimester placenta. Western blot was used to determine the expression of SLP2, PCNA, Cyclin D3, N-cadherin, Vimentin, PGC1α and PPARα in HTR-8/SVneo cells. SLP2 was knocked down in the HTR-8/SVneo cells by using si-Slp2. Wound healing and migration assays were used to determine the effect of SLP2 knockdown on the migration and invasion in the HTR-8/SVneo cells. Mitochondrial membrane potential, reactive oxygen species (ROS), ATP production and biogenesis were measured to assess the effects of SLP2 knockdown on mitochondrial functions.

SLP2 was strongly expressed in the cytotrophoblasts (CTB), syncytiotrophoblast (STB) and extravillous trophoblasts (EVT) of normal pregnancy placenta as compared to miscarriage placenta. SLP2 was highly expressed in the invasive EVT cell lines, HTR-8/SVneo and HPT-8 compared to the CTB cell line JAR. Knockdown of SLP2 significantly inhibited the migration and invasion of HTR-8/SVneo cells and placental villous explants, and repressed mitochondrial biogenesis and functions in HTR-8/SVneo cells.

Silencing of SLP2 inhibited the proliferation, migration and invasion of HTR-8/SVneo cells via the impairment of mitochondrial functions. This indicates that the downregulation of SLP2 in miscarriage placenta could be part of the pathogenesis and pathophysiology of the disease.

The world is witnessing a steady rise in the prevalence of gestational diabetes mellitus (GDM), correlated with the current obesity epidemic. Both GDM and obesity negatively impact both the health of women but also that of the next generation. GDM and maternal obesity are associated with increased maternal and fetal inflammation and oxidative stress. A safe and effective intervention that can prevent these pathological features, and reduce the intergenerational burden, is required. Phenolic acids, such as punicalagin and curcumin, possess anti-inflammatory and antioxidant properties. Thus, the aim of this study was to examine the effects of punicalagin and curcumin on pro-inflammatory cytokines and chemokines, and antioxidant expression in an in vitro model of inflammation.

Human placenta, visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) explants were obtained at term elective Caesarean section and stimulated with TNF alpha (TNF).

We found that punicalagin and curcumin significantly se their suitability as therapeutic interventions for pro-inflammatory gestational complications, including GDM and maternal obesity.
Subthalamic nucleus deep brain stimulation (STN DBS) for Parkinson disease (PD) normalizes neuronal hypersynchrony in the beta frequency range (13-30Hz). The spatial correspondence of maximal beta power to the site of optimal stimulation along the DBS lead trajectory has been debated.

We determined the trajectory locations of the active contact, maximal beta power, and the dorsal border of the STN (DB-STN) in DBS patients. Beta power profiles were measured during intraoperative microelectrode recording (MER). Active contact locations were assigned during blinded, postoperative DBS programming. The DB-STN was identified both electrophysiologically during MER and anatomically on MRI. After grouping DBS trajectories into quadrants relative to the anatomic STN midpoint, we examined regional variations in the relative trajectory locations of the three entities.

STN DBS significantly improved motor performance for all 13 DBS patients, with active contacts at the DB-STN. Along trajectories passing posterior-medial to the STN midpoint, maximal beta power co-localized with active contacts at the DB-STN (difference Δ=0.4±1.6mm, p=0.57). By contrast, in posterior-lateral trajectories, maximal beta arose within the STN, ventral to active contacts (Δ=1.9±1.3mm, p=0.002). Selleckchem Tofacitinib For trajectories anterior to the STN midpoint, maximal beta power co-localized with the DB-STN, while active contacts were ventral to peak beta power (p=0.05).

Our findings indicate that co-localization of optimal stimulation and beta power varies by anatomical region in STN DBS for Parkinson disease.
