Concurrent myelodysplastic malignancies and plasma cell neoplasms; a clinicopathological study with prognostic implications.

Plasma cell neoplasms (PCN) have infrequently been reported in patients with myelodysplastic syndrome (MDS) and even more rarely in those with myelodysplastic syndrome/myeloproliferative neoplasm (MDS/MPN). We report the clinicopathologic features of 26 patients with bone marrow myelodysplasia accompanied by PCN, including 21 patients with MDS and 5 with MDS/MPN. The clinicopathologic features of the MDS/MPN-PCN were compared to those of the MDS-PCN group and 68 cases of MDS/MPN without PCN, respectively.

Phase-Centric MOCVD Enabled Synthetic Approaches for Wafer-Scale 2D Tin Selenides.

Following an initial nucleation stage at the flake level, atomically thin film growth of a van der Waals material is promoted by ultrafast lateral growth and prohibited vertical growth. To produce these highly anisotropic films, synthetic or post-synthetic modifications are required, or even a combination of both, to ensure large-area, pure-phase, and low-temperature deposition. A set of synthetic strategies is hereby presented to selectively produce wafer-scale tin selenides, SnSe (both x = 1 and 2), in the 2D forms.

Double-Floating-Gate van der Waals Transistor for High-Precision Synaptic Operations.

Two-dimensional materials and their heterostructures have thus far been identified as leading candidates for nanoelectronics owing to the near-atom thickness, superior electrostatic control, and adjustable device architecture. These characteristics are indeed advantageous for neuro-inspired computing hardware where precise programming is strongly required. However, its successful demonstration fully utilizing all of the given benefits remains to be further developed.

Channel Scaling Dependent Photoresponse of Copper-Based Flexible Photodetectors Fabricated Using Laser-Induced Oxidation.

Copper (Cu) oxide compounds (CuO), which include cupric (CuO) and cuprous (CuO) oxide, have been recognized as a promising -channel material with useful photovoltaic properties and superior thermal conductivity. Typically, deposition methods or thermal oxidation can be used to obtain CuO. However, these processes are difficult to apply to flexible substrates because plastics have a comparatively low glass transition temperature.

Free Silicone Injections to the Breast: Delayed Complications and Surgical Management of Sequelae.

This case describes a healthy 37-year-old woman who presented with bilateral breast pain and nodules years after receiving free silicone injections to her breasts. Mammogram revealed extremely dense breasts with innumerable bilateral masses of various sizes. Ultrasound was non-diagnostic due to poor penetration and artifact from silicone.

Epidemiological Characterization of a Directed and Weighted Disease Network Using Data From a Cohort of One Million Patients: Network Analysis.

Background: In the past 20 years, various methods have been introduced to construct disease networks. However, established disease networks have not been clinically useful to date because of differences among demographic factors, as well as the temporal order and intensity among disease-disease associations.

Objective: This study sought to investigate the overall patterns of the associations among diseases; network properties, such as clustering, degree, and strength; and the relationship between the structure of disease networks and demographic factors.

A MEMS ultrasound stimulation system for modulation of neural circuits with high spatial resolution in vitro.

Neuromodulation by ultrasound has recently received attention due to its noninvasive stimulation capability for treating brain diseases. Although there have been several studies related to ultrasonic neuromodulation, these studies have suffered from poor spatial resolution of the ultrasound and low repeatability with a fixed condition caused by conventional and commercialized ultrasound transducers. In addition, the underlying physics and mechanisms of ultrasonic neuromodulation are still unknown.

Well differentiated arginase-1 negative hepatocellular carcinoma.

Background: The diagnosis of hepatocellular carcinoma (HCC) is dependent on the histologic and immunohistochemical analysis of biopsy and resection specimens. The distinction of HCC from metastatic neoplasms is pertinent for treatment and prognostic purposes. Arginase-1 (Arg-1), a marker of hepatocellular differentiation, has shown superior sensitivity and specificity when compared to other immunohistochemical markers of detection of HCC such as hepatocyte paraffin antigen (HepPar-1).

Prognostic Implications of Arginase and Cytokeratin 19 Expression in Hepatocellular Carcinoma After Curative Hepatectomy: Correlation With Recurrence-Free Survival.

Background: The prognostic value of arginase expression in hepatocellular carcinoma (HCC) has been evaluated previously. However, no clear distinction exists yet on the role of arginase-1 as a predictor of recurrence in HCC. Cytokeratin 19 (CK19), a cholangiocytic marker, is occasionally expressed in HCC, but the combination of arginase-1 and CK19 expression has never been evaluated.

Network-based analysis of diagnosis progression patterns using claims data.

In recent years, several network models have been introduced to elucidate the relationships between diseases. However, important risk factors that contribute to many human diseases, such as age, gender and prior diagnoses, have not been considered in most networks. Here, we construct a diagnosis progression network of human diseases using large-scale claims data and analyze the associations between diagnoses.

DHS-21, a dicarbonyl/L-xylulose reductase (DCXR) ortholog, regulates longevity and reproduction in Caenorhabditis elegans.

Dicarbonyl/L-xylulose reductase (DCXR) converts l-xylulose into xylitol, and reduces various α-dicarbonyl compounds, thus performing a dual role in carbohydrate metabolism and detoxification. In this study, we identified DHS-21 as the only DCXR ortholog in Caenorhabditis elegans. The dhs-21 gene is expressed in various tissues including the intestine, gonadal sheath cells, uterine seam (utse) cells, the spermathecal-uterus (sp-ut) valve and on the plasma membrane of spermatids.

Membrane proteomic analysis of human mesenchymal stromal cells during adipogenesis.

Mesenchymal stromal cells (MSCs) have proven useful for cell and immune therapy, but the molecular constituents responsible for their functionalities, in particular, those on the plasma membrane, remain largely unknown. Here we employed both gel and nongel based MS to analyze human MSCs' membrane proteome before and after adipogenesis. 2-DE of cells that were pretreated with membrane impermeable fluorescent dyes revealed that both the whole cell proteome and the cell surface subproteome were independent of donors.

Genome-wide differential gene expression profiling of human bone marrow stromal cells.

Bone marrow stromal cells (BMSCs) reside in bone marrow and provide a lifelong source of new cells for various connective tissues. Although human BMSCs are regarded as highly suitable for the development of cell therapeutics and regenerative medicine, the molecular factors and the networks of signaling pathways responsible for their biological properties are as yet unclear. To gain a comprehensive understanding of human BMSCs at the transcriptional level, we have performed DNA microarray-based, genome-wide differential gene expression analysis with the use of peripheral blood-derived mononuclear cells (MNCs) as a baseline.
