Experiences and perceptions of acute myocardial infarction patients with a prolonged decision-making phase of treatment seeking: A meta-synthesis.

Aims: To describe the experiences and perceptions of acute myocardial infarction (AMI) patients with a prolonged decision-making phase of treatment-seeking.

Background: Previous attempts to reduce the treatment-seeking time of AMI have been less than optimal. Due to the coronavirus disease 2019 (COVID-19) pandemic, the situation of prehospital delay is possibly worse.

Nurses' perceptions regarding barriers to implementing the Internet Plus Nursing Service programme: A qualitative study.

Aim: The aim of this work is to investigate nurses' perceptions of barriers constraining the implementation of the Internet Plus Nursing Service program.

Background: The Internet Plus Nursing Service programme helps meet the demands of an ageing population, people with chronic diseases, the disabled, and home convalescents, and affirms the value of nurses. However, this programme has failed to elicit nurses' active participation, and there is limited knowledge regarding nurses' perceptions of the barriers to the programme's implementation.

A noninvasive indicator for the diagnosis of early hepatitis B virus-related liver fibrosis.

Background And Aims: Liver stiffness measurement (LSM) detected by FibroScan, combined with biochemical indexes, has shown potential values for assessment of liver fibrosis pathological degrees. Here we aimed to investigate a noninvasive method for hepatitis B virus-related liver fibrosis.

Patients And Methods: In all, 307 patients who underwent liver biopsy and LSM measurement were included.

Impact of Preoperative Hepatitis B Virus Levels on Prognosis After Primary and Repeat Hepatectomies for Hepatocellular Carcinoma Patients-a Retrospective Study.

Background: Chronic HBV plays an important role in hepatocellular carcinoma pathogenesis. Previously, most studies have been focusing on HBV DNA levels before the primary curative hepatectomy. However, the association of virus level before repeat hepatectomy with the degrees of inflammation and fibrosis on histopathology and prognosis has not been surveyed.

New complete assignment of X-ray powder diffraction patterns in graphitic carbon nitride using discrete Fourier transform and direct experimental evidence.

To date, there have been only a few studies focusing on the assignment of X-ray diffraction (XRD) patterns in graphitic carbon nitrides (g-CN) and contradictory determination for a broad peak around 12°-14° has been perplexing. In this study, assignments are carried out both theoretically and experimentally. The cell parameters for g-CN are determined as a = b = 8.

Co-culture of hepatoma cells with hepatocytic precursor (stem-like) cells inhibits tumor cell growth and invasion by downregulating Akt/NF-κB expression.

Hepatocytic stem cells (HSCs) have inhibitory effects on hepatocarcinoma cells. The present study investigated the effects of HSC activity in hepatocarcinoma cells . A Transwell co-culture system of hepatocytic precursor (stem-like) WB-F344 cells and hepatoma CBRH-7919 cells was used to assess HSC activity in metastasized hepatoma cells .

Potentials of the elevated circulating miR-185 level as a biomarker for early diagnosis of HBV-related liver fibrosis.

Early diagnosis of liver fibrosis is critical for early intervention and prognosis of various chronic liver diseases. Conventional repeated histological assessment is impractical due to the associated invasiveness. In the current study, we evaluated circulating miR-185 as a potential biomarker to predict initiation and progression of liver fibrosis.

Renal carcinoid tumor with liver metastasis followed up postoperatively for 9 years.

Background: We describe a case of renal carcinoid tumor with liver metastasis followed up postoperatively for 9 years.

Case Presentation: A 33-year-old man presented with left flank dull ache. On the abdominal computed tomography, a solid renal mass in the upper portion of the left kidney was detected.

MiR-9a-5p regulates proliferation and migration of hepatic stellate cells under pressure through inhibition of Sirt1.

Aim: To reveal the functions of microRNAs (miRNAs) with respect to hepatic stellate cells (HSCs) in response to portal hypertension.

Methods: Primary rat HSCs were exposed to static water pressure (10 mmHg, 1 h) and the pressure-induced miRNA expression profile was detected by next-generation sequencing. Quantitative real-time polymerase chain reaction was used to verify the expression of miRNAs.

miR‑27a suppresses the clonogenic growth and migration of human glioblastoma multiforme cells by targeting BTG2.

miR-27a and BTG2 are implicated in gliomagenesis and glioma progression. However, hitherto, a link between miR-27a and BTG2 in glioma has not been reported. In the present study, we investigated the effects of miR-27a on the proliferation and invasiveness of glioblastoma cells in vitro and in a mouse xenograft model and further studied the relation between miR‑27a expression and its target gene BTG2, which was identified by computation prediction algorithms.

Unusual cases of pigmented villonodular synovitis after arthroplasty.

Pigmented Villonodular Synovitis (PVNS) is a relatively rare, benign proliferation lesion of the synovium of large joints. The etiology is varied and unclear. We had report a 79-year-old woman had PVNS after 14 years right hip arthroplasty with metal prosthesis.

Higher LRRFIP1 expression in glioblastoma multiforme is associated with better response to teniposide, a type II topoisomerase inhibitor.

Previous studies from this laboratory indicated that microRNA-21 (miR-21) contributes to chemoresistance of glioblastoma multiforme (GBM) cells to teniposide, a type II topoisomerase inhibitor. We also showed that LRRFIP1 is a target of miR-21. In this study, we found that higher baseline LRRFIP1 expression in human GBM tissue (n=60) is associated with better prognosis upon later treatment with teniposide.

Solar energy harnessing in hexagonally arranged Si nanowire arrays and effects of array symmetry on optical characteristics.

Investigation of solar energy harvesting in hexagonally arranged Si nanowire (NW) arrays is performed through optimizing the structural parameters, such as array periodicity (P), Si NW diameter (D) and length (L). The results demonstrate that there exist wide P and D/P 'windows' for the Si NW arrays, locating around 600 nm and 0.833 (i.

Broadband absorption enhancement in randomly positioned silicon nanowire arrays for solar cell applications.

In this Letter, the optical properties of randomly positioned silicon nanowire arrays are studied. The result shows that position randomization with a filling ratio larger than 36% renders better absorptance over a broadband ranging from 300 to 1130 nm compared to regular structures. The ultimate efficiency of a 48% filling ratio position randomized nanowire structure is 13.
