Aims And Background: Matrix metalloproteinase-7 (MMP-7) and Syndecan-1 (SDC1) are involved in multiple functions during tumorigenesis. We aimed to evaluate the diagnostic and prognostic performance of these serum proteins, as potential biomarkers, in patients with pancreatic ductal adenocarcinoma (PDAC) and benign pancreatic cysts.
Methods: In this case-control study, patients with newly diagnosed PDAC (N = 121) were compared with the benign cyst (N = 66) and healthy control (N = 48) groups. Serum MMP-7 and SDC1 were measured by ELISA. The diagnostic accuracy of their levels for diagnosing PDAC and pancreatic cysts was computed, and their association with survival outcomes was evaluated.
Results: MMP-7 median serum levels were significantly elevated in the PDAC (7.3 ng/mL) and cyst groups (3.7 ng/mL) compared with controls (2.9 ng/mL) (p < 0.001 and 0.02, respectively), and also between the PDAC and cyst groups (p < 0.001), while SDC1 median serum levels were significantly elevated in PDAC (43.3 ng/mL) compared with either cysts (30.1 ng/mL, p < 0.001) or controls (31.2 ng/mL, p < 0.001). The receiver operating characteristic curve analysis area under the curve in PDAC versus controls was 0.90 and 0.78 for MMP-7 and SDC1, respectively, while it was 1.0 for the combination of the two and CA 19-9 (p < 0.001). The combination of the three biomarkers had a perfect sensitivity (100%).
Conclusions: Due to its high sensitivity, this biomarker panel has the potential to rule out PDAC in suspected cases.

The expression of matrix metalloproteinase (MMP)-7 is reported to be correlated with invasion and metastasis of colorectal cancer (CRC). Therefore, the inhibition of MMP-7 would be beneficial for the suppression or prevention of CRC cell invasion and metastasis. The stem bark of Acanthopanax senticosus, a widely used medicinal herb, contains isofraxidin (IF) and chlorogenic acid (CGA) as major components.

Article Synopsis
- Abdominal aortic aneurysm (AAA) is a serious vascular condition that currently only has surgical treatment options for advanced stages, with inflammation playing a key role in its development.* -
- A genetic study used Mendelian randomization to analyze the relationship between various inflammatory factors and AAA, identifying specific factors that could either increase or decrease the risk of developing the condition.* -
- The findings suggest that targeting certain inflammatory factors could offer new strategies for preventing and treating AAA without surgical intervention.*

Background: The pressing need for reliable biomarkers in colorectal cancer (CRC) diagnosis and prognosis is a major global health concern. Current diagnostic methods rely heavily on invasive procedures like colonoscopy, and existing biomarkers such as Carbohydrate Antigen 19-9 (CA19-9) and Carcinoembryonic Antigen (CEA) exhibit limitations in accuracy and specificity.
Aims: This study aims to identify and validate novel biomarkers that can enhance the early detection and diagnostic precision of CRC while overcoming the shortcomings of conventional biomarkers.

Objectives: Peri-implantitis (PI) is the most common biological issue surrounding dental implants. According to current knowledge, the aforementioned complication is not equally distributed across different populations, and gene polymorphisms might be one contributing factor. The current study aimed to examine the association between gene polymorphisms of matrix metalloproteinase- (MMP-) 1, -2, -3, -7, and -13 with PI in an Iranian demographic.

Laryngopharyngeal reflux disease (LPRD) is a prevalent upper airway disorder characterized by inflammation and epithelial damage due to the backflow of gastric contents. Current treatments, primarily proton pump inhibitors (PPIs), often show variable efficacy, necessitating the exploration of alternative or adjunctive therapies. This study investigates the therapeutic potential of a mixture of Hedera helix and Coptidis rhizome (HHCR) in mitigating the pathophysiological mechanisms of LPRD.
