Sonic Hedgehog signaling regulates the optimal differentiation pace from early-stage mesoderm to cardiogenic mesoderm in mice.

Sonic Hedgehog (Shh), encoding an extracellular signaling molecule, is vital for heart development. Shh null mutants show congenital heart disease due to left-right asymmetry defects stemming from functional anomaly in the midline structure in mice. Shh signaling is also known to affect cardiomyocyte differentiation, endocardium development, and heart morphogenesis, particularly in second heart field (SHF) cardiac progenitor cells that contribute to the right ventricle, outflow tract, and parts of the atrium.

Successful pain control of lymphangioma-suspected lesions in pregnancy with acetaminophen and opioids: A case report and literature review.

Lymphangioma causing pain during pregnancy is not widely reported, but surgical treatment was performed in each of the reported cases. In our patient, lesions arose in the retroperitoneal cavity and caused intense pain from 17 weeks of gestation. However, surgical treatment was considered difficult because of the location of the lesion.

Prediction of grading of ovarian endometrioid carcinoma using conventional MRI features.

Objective: The purpose of this study was to evaluate MRI findings of ovarian endometrioid carcinoma (OEC) as a predictor of histological grade.

Materials And Methods: This study included 60 patients with histopathologically confirmed OEC (20, 30, and 10 with grades 1, 2, and 3, respectively). Clinical and MRI results were retrospectively reviewed.

Subsequent bacteremia associated with intravascular catheter colonization with Staphylococcus aureus, Gram-negative rods, and Candida species in children.

Subsequent bacteremia developed in 14% of patients with positive catheter tip cultures but concurrent negative blood cultures. The occurrence of subsequent bacteremia did not differ significantly by pathogens (Staphylococcus aureus, Gram-negative rods [GNR], and Candida spp.).

RNA-binding proteins hnRNPM and ELAVL1 promote type-I interferon induction downstream of the nucleic acid sensors cGAS and RIG-I.

The cytosolic nucleic acid sensors RIG-I and cGAS induce type-I interferon (IFN)-mediated immune responses to RNA and DNA viruses, respectively. So far no connection between the two cytosolic pathways upstream of IKK-like kinase activation has been investigated. Here, we identify heterogeneous nuclear ribonucleoprotein M (hnRNPM) as a positive regulator of IRF3 phosphorylation and type-I IFN induction downstream of both cGAS and RIG-I.

Angioimmunoblastic T-cell lymphoma harboring a t(8;14)(q24;q11.2)/TCR::MYC translocation that presented with intestinal infiltration.

Although rearrangement of the MYC oncogene (MYC-R) is frequently observed in aggressive B-cell lymphomas, it is extremely rare in T-cell malignancies. A 64-year-old man who had been under observation for several years because of asymptomatic pulmonary extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALToma) was admitted to our hospital because of poor general condition and hypotension. Blood tests revealed thrombocytopenia and elevated serum lactate dehydrogenase levels, whereas computed tomography revealed systemic lymphadenopathy and splenomegaly.

Mouse models of type I interferonopathies.

Type I interferonopathies are severe monogenic diseases caused by mutations that result in chronically upregulated production of type I interferon. They present with a broad variety of symptoms, the mechanisms of which are being extensively studied. Mouse models of type I interferonopathies are an important resource for this purpose, and in this context, we review several key molecular and phenotypic findings that are advancing our understanding of the respective diseases.

CT scoring system for differentiating of sinonasal inverted papilloma and squamous cell carcinoma arising from inverted papilloma.

Objective: To distinguish squamous cell carcinoma in inverted papilloma (IP-SCC) from IP, the utility of CT scoring system was investigated.

Methods: We extracted cases histopathologically diagnosed with IP and IP-SCC of the sinonasal cavity from June 2004 to May 2021. Preoperative unenhanced CT images were used to evaluate the presence or absence of bone destruction and erosion: Score 1 = positive for bone destruction and/or erosion; Score 0 = negative for bone destruction and erosion.

The Prognostic Impact of Adipophilin Expression on Long-Term Survival Following Liver Resection in Patients with Colorectal Liver Metastases.

: Adipophilin (ADP) is a protein associated with lipid droplets, and its expression is related to poor prognosis in certain cancers. However, its impact on the survival of patients with colorectal liver metastases (CRLMs) remains unclear. This study investigated the impact of ADP expression on long-term survival following hepatectomy in patients with CRLM.

MRI characteristics of ovarian metastasis: differentiation from stomach and colorectal cancer.

Purpose: To evaluate the efficacy of MRI findings for differentiating between ovarian metastasis from stomach cancer (OMSC) and colorectal cancer (OMCC).

Methods: Twenty-six patients with histopathologically proven ovarian metastasis (n = 8 with 12 OMSCs and n = 18 with 25 OMCCs) were enrolled in the study. All patients had undergone pelvic MRI before surgery.

Optimized versus conventional trigger threshold for pancreatic phase image acquisition using dual-energy CT at 40-keV: a randomized controlled trial.

Purpose: To evaluate the impact of optimized trigger threshold on 40-keV pancreatic phase images acquired with a dual-energy CT (DECT) protocol.

Methods: A cohort of 69 consecutive participants (median age, 72 years) undergoing a pancreatic protocol DECT examination between September to December 2021 were prospectively randomized into two protocols: conventional trigger threshold of 100 HU (Group A, n = 34) and optimized trigger threshold of 30 HU (Group B, n = 35). Pancreatic phase image acquisition was performed with fixed delay of 20 s from the trigger threshold.

Quantitative spatial visualization of X-ray irradiation via redox reaction by dynamic nuclear polarization magnetic resonance imaging.

The dose of X-ray irradiation is commonly measured by point assessment with an ionization chamber dosimeter. However, to achieve spatially accurate delivery of X-ray to avoid the exposure to normal tissues, an accurate imaging method for spatially and quantitatively detecting exposure is required. Herein, we present a novel method to visualize X-ray exposure using low-field dynamic nuclear polarization magnetic resonance imaging (DNP-MRI) with nitroxyl radical tempol as the chemical dosimeter.

Materials And Methods: This study included 79 patients with histopathologically proven thyroid cancer (14 ATCs, 8 PDTCs, and 57 PTCs) who underwent neck MRI. MRI images were retrospectively reviewed and compared between the three pathologies.

NaV1.1 contributes to the cell cycle of human mesenchymal stem cells by regulating AKT and CDK2.

Non-excitable cells express sodium voltage-gated channel alpha subunit 1 gene and protein (known as SCN1A and NaV1.1, respectively); however, the functions of NaV1.1 are unclear.

Joint segmentation of sternocleidomastoid and skeletal muscles in computed tomography images using a multiclass learning approach.

Deep-learning-based methods can improve robustness against individual variations in computed tomography (CT) images of the sternocleidomastoid muscle, which is a challenge when using conventional methods based on probabilistic atlases are used for automatic segmentation. Thus, this study proposes a novel multiclass learning approach for the joint segmentation of the sternocleidomastoid and skeletal muscles in CT images, and it employs a two-dimensional U-Net architecture. The proposed method concurrently learns and segmented segments the sternocleidomastoid muscle and the entire skeletal musculature.
