Article Synopsis
  • Single-cell and single-nucleus genomic techniques offer unbiased insights into cellular diversity and function, especially in the nervous system.
  • The concept of a molecular cell atlas is explored, emphasizing how single-cell omics can help formulate hypotheses about cell changes during development and disease.
  • Key considerations for study design, implementation, and awareness of potential limitations and challenges are discussed to improve research outcomes.

Molecular studies have identified various treatment-related prognostic molecules to enhance the effectiveness of colorectal cancer (CRC) treatment and improve survival rates. The expression of cathepsin V in gastrointestinal cancer cells prompted an investigation into its potential as a prognostic indicator for CRC. The evaluation of cathepsin V expression and its clinicopathological significance was conducted through immunohistochemistry in a tissue microarray, encompassing 142 CRC and normal colorectal tissues.

Purpose: Although protein-induced vitamin K absence or antagonist II (PIVKA-II) has been used as a diagnostic tool for hepatocellular carcinoma (HCC), its prognostic value remains unclear.

Methods: This was a nationwide multicenter study using the database of the Korean Liver Cancer Association. Patients with hepatitis B-related HCC who underwent liver resection as the first treatment after initial diagnosis (2008-2014) were selected randomly.

Despite the technical limitations of minimally invasive surgery, laparoscopic total mesorectal excision (LTME) for rectal cancer has short-term advantages over open surgery, but the pathological outcomes reported in randomized clinical trials are still in controversy. Minimally invasive robotic total mesorectal excision (RTME) has recently been gaining popularity as robotic surgical systems potentially provide greater benefits than LTME. Compared to LTME, RTME is associated with lower conversion rates and similar or better genitourinary functions, but its long-term oncological outcomes have not been established.

Background: Isolated superior mesenteric artery dissection (ISMAD) was previously considered a rare disorder; however, this condition has been increasingly diagnosed as time progressed. Although treatment regimen and treatment outcomes have become clearer, the optimal treatment strategy has not yet been well established.

Materials And Methods: This study included 54 patients diagnosed with ISMAD by computed tomography (CT) between November 2004 and December 2017.

Squalene epoxidase (SE), coded by is an important rate-limiting enzyme in the cholesterol biosynthetic pathway. Recently, the aberrant expression of , which is responsible for epithelial to mesenchymal transition (EMT), has been reported in various types of cancer. This study was undertaken to clarify the clinicopathologic implications of SE in patients with stage I to IV colorectal cancer (CRC).

Tumor progression locus 2 (TPL2) is a mitogen-activated protein kinase (MAPK) kinase kinase (MAP3K). The present study aimed to elucidate the clinicopathological significance and prognostic role of TPL2 expression in colorectal cancer (CRC) through immunohistochemistry. In the present study, the correlations between TPL2 expression and clinicopathological parameters, including survival rate, were investigated using 262 archival paraffin-embedded CRC tissue samples.

Background: Thymosin β is a multi-functional hormone-like polypeptide, being involved in cell migration, angiogenesis, and tumor metastasis. This study was undertaken to clarify the clinicopathologic implications of thymosin β expression in human colorectal cancers (CRCs).

Methods: We investigated tissue sections from 143 patients with CRC by immunohistochemistry.

Purpose: A robotic system was mainly designed to allow precise dissection in deep and narrow spaces. We report the clinical and oncologic outcomes of totally robotic total mesorectal excision for rectal cancer.

Methods: Between July 2009 and January 2012, 60 consecutive patients undergoing robotic surgery for rectal cancer at the Eulji University Hospital were included.

Purpose: Recently, randomized controlled trials have reported that conservative therapy can be a treatment option in patients with noncomplicated appendicitis. However, preoperative diagnosis of noncomplicated appendicitis is difficult. In this study, we determined predictive factors to distinguish patients with noncomplicated appendicitis from those with complicated appendicitis.

The ability to achieve pathologic downstaging after neoadjuvant chemoradiotherapy (NCRT) is correlated with improved survival in locally advanced rectal cancer (LARC). However, there is no effective predictive markers. In this study, the expression of angiogenic markers was evaluated in pre-treatment biopsies and corresponding post-treatment resection specimens, and were correlated to histopathological tumour characteristics and response.

Purpose: Chemotherapy-induced nausea and vomiting (CINV) have a negative impact on patients' quality of life and frequently pointed to as a major factor for treatment abandonment. Serotonin (5-HT3) receptor antagonist is considered as key treatment for CINV. Ramosetron and palonosetron are recently developed 5-HT3 receptor antagonists and known as more superior than other first-generation 5-HT3 receptor antagonists.

Background: Isolated superior mesenteric artery dissection (ISMAD) is not a rare disease. However, its optimal treatment strategy has not yet been established.

Methods: This study included 13 consecutive patients with ISMAD who were treated between April 2010 and July 2013 according to published treatment guidelines.

Purpose: The purpose of this study is to evaluate the perioperative and long-term oncologic outcomes of hand-assisted laparoscopic surgery (HALS) and standard laparoscopic surgery (SLS) and assess the role of HALS in the management of right-sided colon cancer.

Methods: The study group included 53 patients who underwent HALS and 45 patients who underwent SLS for right-sided colon cancer between April 2002 and December 2008.

Results: The patients in each group were similar in age, American Society of Anesthesiologist (ASA) score, body mass index, and history of previous abdominal surgeries.
