This is a case report of Epstein-Barr virus (EBV) uveitis confirmed via aqueous humor polymerase chain reaction (PCR) and metagenomics. This 72-year-old male with a history of diabetes and herpes zoster complained of redness and blurred vision in his right eye for eight months. Mild conjunctival injection, anterior chamber cells, mutton-fat keratic precipitates, and vitreous haze were noted.

Background: Genomic alterations play important roles in the development of cancer. We explored the impact of protein-coding genes and transcriptomic changes on clinical and molecular alterations in Taiwanese hepatocellular carcinoma (HCC) patients.

Methods: We analyzed 147 whole-exome sequencing and 100 RNA sequencing datasets of HCC and compared them with The Cancer Genome Atlas (TCGA)-Liver Hepatocellular Carcinoma cohort and develop a panel of 81 apoptosis-related genes for molecular classification.

Background: Cancer is a major cause of death, and its early identification and intervention have potential for clinical actionability and benefits for human health. The studies using whole-genome sequencing (WGS) and large samples analysis of cancer-related genes have been rarely done.

Methods: We performed WGS to explore germline mutations in coding and non-coding areas of cancer-related genes and non-coding driver genes and regulatory areas.

Article Synopsis
  • This study compared the analytical sensitivity and clinical performance of two SARS-CoV-2 testing methods: the Cobas SARS-CoV-2 Test (Cobas 6800 system) and the Cobas SARS-CoV-2 & Flu A/B Test (cobas Liat system).
  • The Cobas Liat system showed better sensitivity with a lower detection limit (12.5-25 copies/mL) compared to the Cobas 6800 system (25-50 copies/mL).
  • Both tests demonstrated high accuracy, with the Cobas 6800 showing 89.36% positive and 98.82% negative percent agreement, making them reliable for early virus detection and decision-making during the COVID-19

Article Synopsis
  • * Results showed that a significant percentage of both cancer patients (38.04%) and healthy controls (46.81%) had CH-related mutations, with older cancer patients having higher occurrence rates.
  • * The presence of specific pathogenic mutations was linked to poorer overall survival in cancer patients, highlighting the clinical relevance of these findings in understanding cancer outcomes.

Numerous vehicle detection methods have been proposed to obtain trustworthy traffic data for the development of intelligent traffic systems. Most of these methods perform sufficiently well under common scenarios, such as sunny or cloudy days; however, the detection accuracy drastically decreases under various bad weather conditions, such as rainy days or days with glare, which normally happens during sunset. This study proposes a vehicle detection system with a visibility complementation module that improves detection accuracy under various bad weather conditions.

Next-generation sequencing (NGS) technology is currently used to establish mutational profiles in many heterogeneous diseases. The aim of this study was to evaluate the mutational spectrum in Taiwanese patients with colorectal cancer (CRC) to help clinicians identify the best treatment method. Whole-exome sequencing was conducted in 32 surgical tumor tissues from patients with CRC.

Background: Osteoarthritis (OA) is a slow progressing, degenerative disorder of the synovial joints. Guilu Erxian Glue (GEG) is a multi-component Chinese herbal remedy with long-lasting favorable effects on several conditions, including articular pain and muscle strength in elderly men with knee osteoarthritis. The present study aimed to identify the effects of Guilu Erxian Paste (GE-P) and Liquid (GE-L) extracted from Guilu Erxian Glue in anterior cruciate ligament transection (ACLT)-induced osteoarthritis mice, and to compare the effectiveness of different preparations on knee cartilage degeneration during the progression of osteoarthritis.

Article Synopsis
  • This study investigates the use of circulating tumor DNA (ctDNA) as a noninvasive method to analyze genetic mutations in various cancers and compares these findings with tissue mutations.
  • 21 cancer patients provided paired tissue and plasma samples, which underwent next-generation sequencing to identify mutations across a comprehensive panel of 275 genes.
  • The results showed that while both methods identified some concordant mutations, combining their findings increased the proportion of patients with actionable mutations, supporting the complementary role of ctDNA in cancer genetic analysis.

Diabetic nephropathy (DN) is the leading cause of end-stage renal disease in diabetes mellitus. Oxidative stress, insulin resistance and pro-inflammatory cytokines have been shown to play an important role in pathogeneses of renal damage on type 2 diabetes mellitus (DM). Inonotus obliquus (IO) is a white rot fungus that belongs to the family Hymenochaetaceae; it has been used as an edible mushroom and exhibits many biological activities including anti-tumor, anti-oxidant, anti-inflammatory and anti-hyperglycemic properties.
