Article Synopsis
  • Photodynamic therapy (PDT) combined with chemotherapy shows improved treatment effectiveness for tumors, particularly hepatocellular carcinoma (HCC), through a method using specially designed lipid vesicles to deliver a photosensitizer and Regorafenib.
  • The study demonstrated that the combined treatment (Lipo-Ce6@Rego-PDT) resulted in significantly higher cytotoxic effects and increased cellular apoptosis in HCC cells compared to PDT alone.
  • Additionally, the combination therapy exhibited good safety profiles as indicated by stable body weight and normal organ staining, confirming its potential for enhanced anti-tumor efficiency and biosafety in clinical applications.

BACKGROUND Hyperphosphatemia is a complication of chronic renal failure (CRF) due to reduction in the glomerular filtration rate. Lanthanum carbonate is a commonly used phosphate binder for patients with CRF and hyperphosphatemia, but has adverse effects if patients are not monitored. This report is of a 47-year-old man with hyperphosphatemia due to CRF treated with lanthanum carbonate tablets who presented acutely with partial large bowel obstruction.

In this study, we aimed to evaluate the diagnostic value of serological assay for SARS-CoV-2. A newly-developed ELISA assay for IgM and IgG antibodies against N protein of SARS-CoV-2 was used to screen the serums of 238 admitted hospital patients between February 6 and February 14, 2020 with confirmed or suspected SARS-CoV-2. SARS-CoV-2 RNA was detected on pharyngeal swab specimens using real time RT-PCR.

Inspired by nature, large-area stable superhydrophobic poly(dimethylsiloxane) (PDMS) films have generated extensive interest for various applications such as self-cleaning, corrosion protection, liquid transport, optical services, and flexible electronics. However, the current methods used to prepare such films are difficult to apply for efficient large-area fabrication. In this article, an effective technique for fabricating low adhesive superhydrophobic films based on the use of a chemically etched template followed by a thermal curing process is introduced.

Article Synopsis
  • Recent research indicates that microRNA-519a (miR-519a) is an oncomir linked to cancer progression, particularly in hepatocellular carcinoma (HCC).
  • Elevated levels of miR-519a in HCC tissues correlate with poor clinical outcomes, such as larger tumor size and lower survival rates.
  • The study identifies FOXF2 as a target of miR-519a, demonstrating that miR-519a promotes cancer cell growth and survival while inhibiting apoptosis by repressing FOXF2 expression.

Gastric cancer (GC) is one of the most common malignant tumors worldwide. No fundamental improvements in the five-year survival rates of patients with GC have been reported due to a low early diagnosis rate. Therefore, the identification of novel biomarkers is urgently required for an early diagnosis of GC.

Large amount of expression data were generated by high-throughput experimental techniques such as microarray. Single algorithm cannot be widely accepted as suitable method for mining of gene expression data. Therefore, integration of different algorithms and extraction of more useful information from the expression data are the key problems for identification of biomarkers.

We previously analyzed the microRNA (miRNA) expression pattern in gastric cancer with and without recurrence and obtained 17 differentially expressed miRNAs with potential to predict recurrence risk for GC patients. In the present study, we aimed to investigate recurrence-related genes which may be regulated by the differentially expressed miRNAs identified in our prior research. Three different miRNA target gene databases (miRanda, TargetScan and PicTar) were used for searching the potential genes regulated by miRNAs.

Notch signaling controls cellular differentiation and proliferation. Recent studies have shown that Notch signaling plays an important role in the carcinogenesis and progression of a growing number of malignant tumors. We investigated the effect of Notch1 activation on human hepatocellular carcinoma (HCC).

Background: Gastric cancer (GC) is one of the most common malignancy and primary cause of death in Chinese cancer patients. Recurrence is a major factor leading to treatment failure and low level of 5-year survival rate in GC patients following surgical resection. Therefore, identification of biomarkers with potential in predicting recurrence risk is the key problem of the prognosis in GC patients.

Colon cancer is the third most common cancer and one of the leading causes of cancer-related death in the world. Therefore, identification of biomarkers with potential in recognizing the biological characteristics is a key problem for early diagnosis of colon cancer patients. In this study, we used a random forest approach to discover biomarkers based on a set of oligonucleotide microarray data of colon cancer.

Hantavirus (HV) infection leads to a kind of severe systematic syndrome, hemorrhagic fever with renal syndrome (HFRS). Heat shock proteins (HSPs) can be used as adjuvants assisting soluble antigens to produce specific targets which can be attacked by cytotoxic T lymphocytes. For further research on HFRS vaccine, this study aimed to express Hantaan virus nucleocapsid protein (HTNV NP)-HSP70 fusion protein in COS-7 cells.
