A Comparative Analysis of Cell Proliferation and Wound Closure in Cultured Gingival Epithelial Cells Using Plasma Rich in Growth Factors and Platelet-Rich Plasma Containing Leukocytes.

Objectives:  Plasma rich in growth factors (PRGF) is presumed to be able to stimulate the regeneration of skin and periodontal tissue. This effect can be attributed to the fact that PRGF contains fewer leukocyte-derived interleukins in comparison to platelet-rich plasma (PRP). However, a comparison of the effects of PRGF and PRP on gingival epithelial cells has not been conducted yet.

The Establishment of a Novel Murine Model of Immune Thrombocytopenia in Pregnancy and the Impacts of Thrombopoietin Receptor Agonist on Platelet Production.

Objective Immune thrombocytopenia (ITP) is frequently associated with pregnancy. However, treatment options for ITP in pregnancy are limited, and there are few animal models available for the establishment of treatments. Here, we aimed to establish a novel murine pregnant model of ITP and to investigate the impacts of thrombopoietin receptor agonist (TPO-RA) on platelet production and reproductive outcomes.

Ectopic expression of the mitochondrial protein COXFA4L3 in human sperm acrosome and its potential application in the selection of male infertility treatments.

Purpose: Spermatogenesis requires a large amount of energy, which is primarily produced by the mitochondrial electron transfer chain. Mitochondrial dysfunction affects male infertility, suggesting a relationship between the electron transfer chain and male infertility. COXFA4L3 (C15ORF48) is an emerging subunit protein of cytochrome oxidase specifically expressed in germ cells during spermatogenesis, and it may be involved in male infertility.

The blue light signaling inhibitor 3-bromo-7-nitroindazole affects gene translation at the initial reception of blue light in young seedlings.

Initial light reception after germination is a dramatic life event when a seedling starts proper morphogenesis. Blue light contains a range of light wavelengths that plants can perceive. A previous report suggested that the chemical compound 3-bromo-7-nitroindazole (3B7N) inhibits blue light-mediated suppression of hypocotyl elongation by physically interacting with the blue light receptor Cryptochrome 1 (CRY1).

Elevated 12,13-diHOME level in maternal and umbilical cord blood complicated with preeclampsia.

Background: Preeclampsia (PE) is a condition in pregnancy characterized by hypertension and proteinuria, thus leading to severe complications for both mother and fetus, including fetal growth restriction (FGR). However, there are still unclear aspects regarding the pathogenesis, prevention, and treatments. This study aimed to elucidate the characteristics of lipid metabolism in maternal and umbilical cord plasma complicated with PE using liquid chromatography-mass spectrometry (LC-MS).

Development of the Pronotal Explanate Margin, a Novel Evolutionary Trait in Tortoise Beetles.

Most tortoise beetles, belonging to the subfamily Cassidinae (Coleoptera: Chrysomelidae), possess distinctive explanate margins, comprising elongations of the pronotum and elytra outer margins. These margins flatten against the ground, serving as a unique defensive mechanism against predators. To understand the developmental and evolutionary origins of explanate margins, we examined the development of the pronotal part of these structures in two tortoise beetle species: (Boheman) (tribe Cassidini) and (Boheman) (tribe Aspidimorphini).

Immunohistochemistry of p53 surrogates mutation as an accurate predictor for early-relapse of surgically resected stage I-III lung adenocarcinoma.

Introduction: is a strong tumor suppressor gene; its deactivation contributes to carcinogenesis and influences clinical outcomes. However, the prognostic influence of p53 deactivation on early relapse in patients with surgically resected non-small cell lung cancer remains unclear.

Materials And Methods: A cohort of 170 patients with primary stage I through III lung adenocarcinoma (LADC) and lung squamous cell carcinoma who underwent complete resection at Tokyo Medical and Dental University was screened for mutations using panel testing, and association studies between mutations and clinical data, including histology and postoperative recurrence, were performed.

Carbon dioxide-enhanced angiography for detection of colonic diverticular bleeding and clinical outcomes.

Purpose: To determine the ability of CO-enhanced angiography to detect active diverticular bleeding that is not detected by iodinated contrast medium (ICM)-enhanced angiography and its impact on clinical outcomes when used to confirm embolization, particularly the risks of rebleeding and ischemic complications.

Materials And Methods: We retrospectively identified a cohort of patients with colonic diverticular bleeding who underwent catheter angiography between August 2008 and May 2023 at our institution. We divided them according to whether they underwent CO angiography following a negative ICM angiography study or to confirm hemostasis post-embolization (the CO angiography group) or ICM angiography alone in the absence of active bleeding or for confirmation of hemostasis post-embolization (the ICM angiography group).

Nogo Receptor Antagonist LOTUS Promotes Neurite Outgrowth through Its Interaction with Teneurin-4.

Neurite outgrowth is a crucial process for organizing neuronal circuits in neuronal development and regeneration after injury. Regenerative failure in the adult mammalian central nervous system (CNS) is attributed to axonal growth inhibitors such as the Nogo protein that commonly binds to Nogo receptor-1 (NgR1). We previously reported that lateral olfactory tract usher substance (LOTUS) functions as an endogenous antagonist for NgR1 in forming neuronal circuits in the developing brain and improving axonal regeneration in the adult injured CNS.

Carbon dioxide angiography during angioembolization for trauma patients increases the detection of active bleeding and leads to reliable hemostasis: a retrospective, observational study.

Background: Angiography with carbon dioxide (CO) has long been used as an alternative when iodine contrast media (ICM) cannot be used due to allergy to iodine or renal dysfunction. Conversely, CO angiography is also known as a provocation method for active bleeding. In this study, we examined the efficacy of CO angiography in angioembolization (AE) for trauma patients.

Of 7294 Enterobacterales strains isolated from independent cases of bacteremia and/or meningitis, 10 (0.

Potential for visualization of intracellular pH gradient in the brain using PET imaging.

Intracellular pH is a valuable index for predicting neuronal damage and injury. However, no PET probe is currently available for monitoring intracellular pH . In this study, we developed a new approach for visualizing the hydrolysis rate of monoacylglycerol lipase, which is widely distributed in neurons and astrocytes throughout the brain.

Transarterial embolization to treat a massive hemothorax during mechanical circulatory support via puncturing of the extracorporeal membrane oxygenation circuit.

Background: Current guidelines recommend the use of mechanical circulatory support (MCS) for patients with cardiogenic shock that is refractory to medical therapy. Bleeding is the most common complication of MCS. Transarterial embolization (TAE) is often performed to treat this complication, because it is a less invasive hemostatic procedure.
