Cervical cancer, often driven by high-risk human papillomavirus (HPV) infections such as HPV16 or HPV18, remains a leading cause of cancer-related deaths. HPV16, found in about 90% of cervical cancer patients, harbors key oncogenic related genes (E6, E7, E2, E5) and an upstream regulatory region (URR) that contribute to cancer progression. This study introduces a novel approach using a recombinant oncolytic herpes simplex virus type 1 (HSV-1) named SONC103, armed with a CRISPR/Cas9 gene editing system.

Article Synopsis
  • Oncolytic virotherapy is a new cancer treatment strategy that uses modified viruses to trigger immune responses specifically against tumors, like the novel oncolytic virus (oHSV1-IL15B) developed from herpes simplex virus-1 (HSV-1) for colon cancer treatment.
  • In experiments with mice, oHSV1-IL15B demonstrated significant tumor-fighting effects, especially when combined with another oncolytic virus (oHSV-1-aPD1), resulting in better tumor inhibition and longer survival rates compared to using these treatments alone.
  • The study revealed that the combination therapies increased the presence of key immune cells (CD8 and CD4 T cells) and improved the tumor's immune environment, suggesting that combining

Indole-3-carbinol (I3C), a compound found in cruciferous vegetables, has shown significant efficacy in treating both cancerous and non-cancerous diseases. Its primary derivative, 3,3'-diindolylmethane (DIM), formed during digestion, also exhibits similar therapeutic benefits. In liver disorders, I3C and DIM exhibit dual roles by inhibiting and promoting hepatocellular carcinoma (HCC) and providing relief for nonmalignant liver diseases, such as acute liver injury (ALI), hepatic fibrosis, nonalcoholic fatty liver disease (NAFLD), and alcohol-related liver disease (ALD).

Ring-array photoacoustic tomography (PAT) system has been widely used in noninvasive biomedical imaging. However, the reconstructed image usually suffers from spatially rotational blur and streak artifacts due to the non-ideal imaging conditions. To improve the reconstructed image towards higher quality, we propose a concept of spatially rotational convolution to formulate the image blur process, then we build a regularized restoration problem model accordingly and design an alternating minimization algorithm which is called blind spatially rotational deconvolution to achieve the restored image.

Blind image deconvolution plays a very important role in the fields such as astronomical observation and fluorescence microscopy imaging, in which the noise follows Poisson distribution. However, due to the ill-posedness, it is a very challenging task to reach a satisfactory result from a single blurred image especially when the power of the Poisson noise is at a high level. Therefore, in this paper, we try to achieve high-quality restoration results with multi-blurred images which are contaminated by Poisson noise.
