Laparoscopic anatomical SVIII resection middle hepatic fissure approach: Caudal or cranio side.

Background: Laparoscopic hepatectomy is a proven safe and technically feasible approach for liver tumor resection, but laparoscopic anatomical SVIII resection (LASVIIIR) remains rarely reported due to poor accessibility, difficult exposure, and the deep-lying Glissonean pedicle. This study examined the safety, feasibility, and perioperative outcomes of LASVIIIR a middle hepatic fissure approach at our institution.

Aim: To investigate the safety, feasibility, and perioperative outcomes of LASVIIIR a middle hepatic fissure approach at our institution.

A Three-Stage Cellular Automata Model of Complex Large Roundabout Traffic Flow, with a Flow-Efficiency- and Safety-Enhancing Strategy.

Intelligent transportation systems (ITSs) present new opportunities for enhanced traffic management by leveraging advanced driving behavior sensors and real-time information exchange via vehicle-based and cloud-vehicle communication technologies. Specifically, onboard sensors can effectively detect whether human-driven vehicles are adhering to traffic management directives. However, the formulation and validation of effective strategies for vehicle implementation rely on accurate driving behavior models and reliable model-based testing; in this paper, we focus on large roundabouts as the research scenario.

Tenofovir versus entecavir on the prognosis of hepatitis B virus-related hepatocellular carcinoma: a reconstructed individual patient data meta-analysis.

Hepatitis B, often leading to Hepatocellular carcinoma (HCC), poses a major global health challenge. While Tenofovir (TDF) and Entecavir (ETV) are potent treatments, their comparative effectiveness in improving recurrence-free survival (RFS) and overall survival (OS) rates in HBV-related HCC is not well-established. We conducted an individual patient data meta-analysis using survival data from randomized trials and high-quality propensity score-matched studies to compare the impact of Tenofovir (TDF) and Entecavir (ETV) on RFS and OS in HBV-related HCC patients.

Laparoscopic Anatomical Segment VII Resection for Hepatocellular Carcinoma Using the Glissonian Approach with Indocyanine Green Dye Fluorescence.

Background: Many studies confirm that anatomical resection was associated with favorable oncologic outcomes for patients with HCC who had preserved as much of the remnant liver tissue as possible. In recent years, laparoscopic liver resection has been widely extended from minor resection to complex hepatectomy, However, surgery on tumors located in the posterosuperior segment remains a demanding procedure regardless of the extent of resection. Laparoscopic anatomical segment VII resection has one of the highest difficulty scores based on the tumor location due to poor accessibility, hard to exposure, and difficulty in obtaining sufficient surgical margins.

Major hepatectomy for primary hepatolithiasis: a comparative study of laparoscopic versus open treatment.

Background: Due to higher technical requirements, laparoscopic major hepatectomy (LMH) for primary hepatolithiasis have been limited to a few institutions. This retrospective study was performed to evaluate the therapeutic safety, and perioperative and long-term outcomes of LMH versus open major hepatectomy (OMH) for hepatolithiasis.

Methods: From January 2012 to December 2016, 61 patients with hepatolithiasis who underwent major hepatectomy were enrolled, including 29 LMH and 32 OMH.

Concomitant non-Hodgkin's lymphoma in colon and liver: report of a rare case and review of literature.

A 58-year-old male patient was admitted with right upper abdominal pain. Initial hematologic evaluation revealed mildly elevated serum carcinoembryonic antigen and carbohydrate antigen (CA) 19-9 tests, while an abdominal CT-scan showed a circumferential mass along the distal ascending colon and the right flexure of colon, simultaneously a liver lesion in segment 8 is considered metastases from colorectal. colonoscopic examination revealed a circumferential growth tumor in the right flexure of colon and the colonoscopy can not reach the proximal of the tumor.

DNA methylation profiling identifies EYA4 gene as a prognostic molecular marker in hepatocellular carcinoma.

Background: DNA hypermethylation plays important roles in carcinogenesis by silencing key genes. This study aims to identify pivotal genes in hepatocellular carcinoma (HCC) by DNA methylation microarray and to assess their prognostic values.

Materials And Methods: DNA methylation microarray was performed in 45 pairs of HCC and adjacent nontumorous tissues and six normal liver tissues to identify hypermethylated genes in HCC.

[Cloning, expression and phylogenetic analysis of Schistosoma japonicum calcyphosine gene].

Objective: To clone and express Schistosoma japonicum (Sj) calcyphosine gene, and purify the expressed protein.

Method: The encoding sequence selected from Sj cDNA library was amplified by PCR. After subcloned into prokaryotic expression vector pET-28a, the expressed protein was purified with His -Tag affinity chromatography.

[Diversity and function of symbiotic microbes in the gut of lower termites].

The gut of lower termites harbor a complex microbial community, including eukaryotic flagellates and prokaryotic bacteria and archaea, which play important roles in the wood-cellulose digestion of these termites. The hindguts of lower termites are characterized with an enlarged paunch with steep oxygen and hydrogen gradient and not randomly distributed abundant microorganisms. The symbiotic flagellates in the gut of lower termites, which are normally associated with epibionts or endobionts, are phylogenetically affiliated with Trichomonadida, Hypermastigida and Oxymonadida.

[Characterization of resistant cell line of Trichoplusia ni to Bacillus thuringiensis toxin Cry1Ac].

The cell line (BTI-TN-5B1-4) of Trichoplusia ni had been selected by Bacilllus thuringiensis (Bt) toxin Cry1Ac for 86 generations continuously. A high level of resistance was achieved and the partial characterizations of the resistance-selected BTI-TN-5B1-4 cells were studied in order to explore the mechanism of the resistance to Bt toxin. The cells selected by Cry1Ac had low level of cross-resistance (19.
