Advertisement calls from species of the Limnonectes hascheanus-limborgi complex (Anura: Dicroglossidae) from Peninsular Malaysia.

Limnonectes hascheanus and Limnonectes limborgi are two very similar-looking and closely related species and are sometimes referred to as the Limnonectes hascheanus-limborgi complex (Inger & Stuart 2010). Inger & Stuart (2010) tackled the systematics of the complex and confirmed the status of L. limborgi as a distinct species and not a junior synonym to L.

Non-iatrogenic implantation of cutaneous metastasis from hepatocellular carcinoma.

Purpose: Cutaneous metastases as an extrahepatic metastasis from hepatomas (HCC) is extremely rare and always carry a poor prognosis and less survival time. Previously, there has been a limited number of literature that reported skin metastasis in a large number of cases, which has rarely been discussed in the empirical treatment and therapy of cutaneous metastasis, especially for non-iatrogenic implantation. It is necessary to discuss this kind of metastasis.

Single-center Experience in the Diagnosis and Treatment of Hepatic Perivascular Epithelioid Cell Neoplasm.

Background And Aims: Perivascular epithelioid cell neoplasms (PEComas) are a rare type of mesenchymal neoplasm and their preoperative diagnosis is challenging. In this study, we summarized the experience from a single medical center to study the examinations, clinical presentations, and pathological and histological characteristics of PEComas in the liver in order to optimize overall understanding of the diagnosis and treatment of these neoplasms.

Methods: We conducted a retrospective analysis to investigate the clinical and pathological characteristics as well as imaging presentations of 75 patients diagnosed with hepatic PEComa in The First Affiliated Hospital of Zhejiang University between April 2010 and April 2020.

MiR-25 enhances autophagy and promotes sorafenib resistance of hepatocellular carcinoma via targeting FBXW7.

Sorafenib resistance is a major challenge in the treatment of patients with advanced hepatocellular carcinoma (HCC). MicroRNAs (miRNAs) are a large family of non-coding RNA molecules, which is an important mechanism of drug resistance. We previously found that knockdown of miR-25 increased the sensitivity of TRAIL-induced apoptosis in liver cancer stem cells.

Spatiotemporal patterns of anuran functional diversity in temperate montane forests.

Functional diversity is an integrative approach to better understand biodiversity across space and time. In the present study, we investigated the spatiotemporal patterns (i.e.

A Nomogram Estimation for the Risk of Microvascular Invasion in Hepatocellular Carcinoma Patients Meeting the Milan Criteria.

Objective: We aimed to develop and validate a nomogram for preoperatively estimating the risk of microvascular invasion (MVI) in hepatocellular carcinoma (HCC) within the Milan criteria.

Methods: The clinical data of 312 HCC patients who underwent liver surgery at the xxx from Jan 2017 to Dec 2019 were retrospectively collected. Then, the study population was categorized into the training and validation group based on the date of surgery.

Multiple myeloma with CD138 changed from positive to negative: A case report.

Background: Multiple myeloma (MM) is a common malignant disease of the blood system, caused by the neoplastic proliferation of plasma cells that accumulate in bone marrow (BM). Here, we report a case of MM patient with CD138 marker changed from positive to negative.

Methods: BM and peripheral blood samples from a 48-year-old patient with MM were examined and analyzed by conventional morphology, flow cytometry, and immunodetection.

Spatial and temporal patterns of amphibian species richness on Tianping Mountain, Hunan Province, China.

Exploring species richness patterns across space and time can help in understanding species distribution and in formulating conservation strategies. Among taxa, amphibians are of utmost importance as they are highly sensitive to environmental changes due to their unique life histories (Zhong et al., 2018).

AntagomiR-199a Enhances the Liver Protective Effect of Hypoxia-Preconditioned BM-MSCs in a Rat Model of Reduced-Size Liver Transplantation.

Background: Reduced-size liver transplantation (LT) was invented to overcome the shortage of donor livers; however, it has proven to be more susceptible to ischemia-reperfusion injury. Bone marrow-derived mesenchymal stem cell infusion has been shown to be protective following LT. Optimization of MSC infusion has been performed, among which hypoxia preconditioning and miRNA modulation have shown promise.

Liver vessel segmentation based on extreme learning machine.

Liver-vessel segmentation plays an important role in vessel structure analysis for liver surgical planning. This paper presents a liver-vessel segmentation method based on extreme learning machine (ELM). Firstly, an anisotropic filter is used to remove noise while preserving vessel boundaries from the original computer tomography (CT) images.

[Influence of AML1 and AML1-ETO on transcriptional regulation of nucb2 gene].

This study was purposed to investigate the effect of AML1-ETO fusion protein resulted from hematopoietic transcription factor (AML1) and acute myeloid leukemia M(2b)(AML-M(2b)) on transcription activity of nucleobindin 2 (nucb2) promoter, and to explore the role of AML1-ETO in molecular pathogenesis of AML-M(2b). The real-time RT-PCR was used to study the regulation of AML1-ETO on nucb2 at transcription level in AML1-ETO inducible leukemia cell line, the chromatin immunoprecipitation (ChIP)-based qPCR was used to investigate the direct in vivo interaction between the AML1, AML1-ETO and nucb2 promoter in AML1-ETO positive leukemia cell line, the luciferase report gene assay was used to detect the regulation of AML1, AML1-ETO on the transcription activity of nucb2 promoter. The results showed that the expression level of nucb2 was reduced with the increase of AML1-ETO.
