Brain development using a multicomponent intravenous lipid emulsion in preterm infants.
BMC Pediatr
December 2024
Developing Brain Institute, Children's National Hospital, 111 Michigan Avenue, NW, Washington, DC, USA.
Background: Intravenous lipid emulsions are an essential component of nutritional support for very preterm infants. Many neonatal intensive care units have transitioned from traditional soybean oil-only to fish oil-containing multicomponent lipid emulsions, but the neurodevelopmental implications have not been well-explored. The primary aim of this study was to assess extrauterine third trimester brain growth in very preterm infants supported with soybean oil-only compared to fish-oil containing multicomponent lipid emulsions; white matter development and neurobehavioral regulation at term were also investigated.

To address this, we trained adult mice born a day early (preterm mice) on a visual discrimination task and found that they commit more errors and fail to achieve high levels of performance. Using , we found that the neurons in the primary visual cortex (V1) and the V1-projecting prefrontal anterior cingulate cortex (ACC) are hyper-responsive to the reward, reminiscent of cue processing in adolescence.

Department of Gynecologic Oncology, Ankara Bilkent City Hospital, Faculty of Medicine, University of Health Sciences, Ankara, Turkey.
Objective: The primary objective of this study was to identify the risk of metastasis to lymph nodes above the inferior mesenteric artery (IMA) in endometrioid-type endometrial cancer (EC) and the factors that influence metastasis.
Methods: The study included patients who had been operated on for endometrioid-type EC in three gynecological oncology centers between 2007 and 2023. The supramesenteric lymph node (SM-LN) is the region between the left renal vein and the IMA, whereas the inframesenteric lymph node (IM-LN) is the region between the IMA and the aortic bifurcation, as determined by the level of the IMA.
Portable-size artificial uterine system for viviparous shark embryos.
MethodsX
December 2024
Okinawa Churashima Research Institute, Okinawa Churashima Foundation, Motobu, Japan.
In this study, we developed a portable artificial uterus specifically designed for viviparous elasmobranchs (sharks and batoids). This new method is different from the previous method owing to the absence of fluid-cleaning filters, a smaller amount of incubation fluid, and the use of a mini-sized refrigerator for temperature control. Due to these modifications, the total weight decreased to approximately 40 kg, which is less than one-twentieth that of the previous system.

Primary pelvic peritoneal masses, not arising from major organs, are uncommon in adults. Leiomyomas are a group of benign smooth muscle tumors, most commonly found in the uterus in premenopausal women (70-80%). Extra-uterine locations are very rare and more frequent in women.
