The purpose of this study is to analyze the influence of InGaAlP diode laser (660 nm) with or without an odontogenic medium (OM) in the functional activity of OD-21 cells. Undifferentiated OD-21 pulp cells were cultivated with or without OM and divided into four groups (n = 5) nonirradiated control (C -), nonirradiated + OM (C +), irradiated (L -), and irradiated + OM (L +). Laser application was performed in two sessions of a 24-h interval with an irradiance of 11.3 mW/cm2, energy density of 1 J/cm2, and total cumulative energy/well of 4.6 J. Cell proliferation, VEGF-164 expression, mineralization, and expression of Alp, Runx2, and Dmp1 genes, as well as immunolocalization of RUNX2 and MEPE proteins, were evaluated. mTOR inhibitor Data were analyzed by statistical tests (α = 0.05). All studied groups showed a similar increase in cell proliferation with or without OM. After 7 and 10 days, a significatively higher concentration of VEGF-164 in L - group when compared to C - group was observed. A significant increase in mineralized nodules in the L + was noted when compared to C + in the same conditions. Photobiomodulation upregulated significantly Runx2 and Dmp1 expression after 10 days in L - and after 7 days in L + , with downregulation of Dmp1 after 10 days in L + group. Immunolocalization of RUNX2 and MEPE was expressive after 7 days of culture in the cytoplasm adjacent to the nucleus with a decrease after 10 days, regardless of the presence of OM. Photobiomodulation enhances metabolism associated with angiogenesis, gene expression, and mineralization regardless of the odontogenic medium in OD-21 cells.Long grain geng/japonica rice has a higher market preference due its excellent appearance quality. The dense and erect-panicle 1 (dep1) gene has been widely used in the breeding of high-yielding geng/japonica rice cultivars in China. link2 However, this gene causes short and round grain shape thus making it less attractive in global rice markets. Therefore, breeding of high-yielding long-grain geng/japonica rice cultivars by incorporating dep1 with major-effect grain shape gene is of high priority in rice industry. Up to now, multiple grain shape genes' effect mechanism has been clearly elaborated, however, under the background of erect-panicle geng/japonica rice, the effect of major grain shape genes on the appearance quality need to be further clarified, as detailed reports are limited. Utilizing CRISPR/Cas9 technology, a series of near-isogenic lines (NILs) (YF47dep1-gw8, YF47dep1-gs3, YF47dep1-gl7, YF47dep1-qgl3 and YF47dep1-tgw6) in Yanfeng 47(YF47dep1) background were created. Grain appearance and yield compoearance quality and yield improvement, GS3 and TGW6 alleles can be applied directly for breeding long-grain shape geng/japonica rice, and editing GW8 resulted in excellent appearance quality but low yield, therefore, this gene would be difficult to use directly but can be considered as the core germplasm resource.
Numerous studies have suggested that metformin treatment can increase breast cancer survival; however, it is unclear whether its effects interact with intrinsic subtype or diabetic status. Therefore, we conducted a large nationwide study to assess this in women with surgically resected invasive breast cancer.
Patients with newly diagnosed breast cancer between 2007 and 2016 were identified using the national health insurance claims database of South Korea. Metformin or other drug exposures was defined as medication for ≥ 90days. Breast cancer subtypes were classified into four groups based on hormonal therapy and anti-HER2 treatments.
A total of 117,333 patients were included (median follow-up duration, 90months). Type 2 diabetes mellitus (T2DM) affected significantly overall survival (OS, 7years, 89.7% vs. 92.4%, p < 0.001). A significant interaction was found between the use of metformin and insulin in patients with T2DM (p = 0.018). Thus, the subsequent analysis was limited to these patients and p, the presence of T2DM, and the use of insulin.
In this review paper, we examine the latest evidence regarding the use of iron supplementation, erythropoiesis-stimulating agents (ESAs), and blood transfusions as therapeutic targets for anemia to mitigate morbidity and mortality in patients with cardiovascular disease.
Intravenous ferric carboxymaltose (FC) injections in heart failure (HF) have resulted in improved self-reported patient symptoms; higher exercise capacity, as measured by 6-min walk test distance in anemic patients; and lower re-hospitalization rates in iron deficient patients. Darbepoetin alfa has shown evidence of improved Kansas City Cardiomyopathy Questionnaire scores. No mortality benefits have been noted thus far with FC injections or darbepoetin in HF, with an increase in adverse events with darbepoetin. Aggressive transfusions (Hg < 10g/dL) are not associated with improved outcomes in cardiovascular disease. Quality of life metrics, rather than mortality, appear to improve with IV FC and ESA use in HF. More studies are requiredd to see if these treatments have a role in coronary artery disease. Current evidence suggests that anemia is a marker of underlying disease severity, with a limited role in disease modification. Further studies are required to solidify our understanding of this topic.Plant's stomatal physiology and anatomical features are highly plastic and are influenced by diverse environmental signals including the concentration of atmospheric CO2 and nutrient availability. Recent reports suggest that the form of nitrogen (N) is a determinant of plant growth and nutrient nitrogen use efficiency (NUE) under elevated CO2 (EC). Previously, we found that high nitrate availability resulted in early senescence, enhanced reactive oxygen species (ROS), and reactive nitrogen species (RNS) production and also that mixed nutrition of nitrate and ammonium ions were beneficial than sole nitrate nutrition in wheat. In this study, the interactive effects of different N forms (nitrate, ammonium, mixed nutrition of nitrate, and ammonium) and EC on epidermal and stomatal morphology were analyzed. Wheat seedlings were grown at two different CO2 levels and supplied with media devoid of N (N0) or with nitrate-N (NN), mixed nutrition of ammonium and nitrate (MN), or only ammonium-N (AN). The stoma length in attributes viz. cell length, number of cells, etc. affected the leaf growth responses to EC and forms of N nutrition. These attributes are fine targets for effective manipulation of growth responses to EC.
We evaluated the relationship between mandibular third molar roots (M3Ms) and surrounding cortical bone using cone beam computed tomography (CBCT) and panoramic findings. We studied (a) the location of mandibular third molar roots in relation with cortical bone in terms of contact, penetration, and perforation on CBCT; (b) the relationship between characteristics of a root in panoramic findings and the CBCT image (entire and segmentally); and (c) the relationship of the root plane in panoramic findings vs. CBCT.
One hundred five teeth with 224 roots of mandibular third molar from 73 patients were evaluated by using cone beam computed tomography and panoramic image.
The relationships were assessed using 105 images of impacted M3Ms 104/105 (99%) showed cortical bone involvement (30.4% penetration and 68.6% perforation). The more apical the segment, the higher the proportion of perforation. Most (79.9%) of the M3M roots involved a lingual cortex with 46.9% penetration and 49.2% perforation. The panoramic signs of segmental root images-viz. link3 clear and blurred-were not associated with cortical penetration or perforation. Panoramic signs of individual root images-in the same and different planes-could be used to predict root plane M3M roots. The same appearance in the panoramic image was significantly related to the same plane of the root in CBCT (p-value 0.048).
These findings could contribute to enhanced radiological assessment and surgical planning.

Prostatic artery embolization (PAE) is associated with patients' quality of life improvements and limited side effects compared to surgery. However, this procedure remains technically challenging due to complex vasculature, anatomical variations and small arteries, inducing long procedure times and high radiation exposure levels both to patients and medical staff. Moreover, the risk of non-target embolization can lead to relevant complications. In this context, advanced imaging can constitute a solid ally to address these challenges and deliver good clinical outcomes at acceptable radiation levels.
This technical note aims to share the consolidated experience of four institutions detailing their optimized workflow using advanced image guidance, discussing variants, and sharing their best practices to reach a consensus standardized imaging workflow for PAE procedure, as well as pre and post-operative imaging.
This technical note puts forth a consensus optimized imaging workflow and best practices, with the hope of helping drive adoption of the procedure, deliver good clinical outcomes, and minimize radiation dose levels and contrast media injections while making PAE procedures shorter and safer.

To date, the majority of sexting studies have been conducted online; however, little is known about the extent to which responding to such socially sensitive questions may cause participant discomfort or distress. Research on this question is critical since in the absence of empirical data, institutional review boards (IRBs) may permit or place restrictions on online sexting studies based on an under- or overestimation of adolescent participation risk. The current online study asked 210 girls (aged 14-18 years, 55% non-Hispanic White, with sexting experience in the past 12 months) who previously registered to take online surveys on (1) their anticipated comfort in responding to a sexting survey include items on sexting motivations, positive and negative sexting consequences, and related sexual behaviors; (2) their perceptions of sexting research benefits/harms; and (3) comfort discussing similar topics in everyday life and with health professionals. Overall, participants were comfortable responding to sexting survey questions, rated sexting research as high benefits and low risks, and felt about the same as or more comfortable completing a sexting survey than discussing similar topics with peers, parents, or healthcare professionals. Findings suggest that anonymous online sexting studies can be classified as minimal risk research for adolescent girls and provide empirical support for IRB decisions to waive guardian permission for participation in such studies.
