Immunochemical and urodynamic outcomes after polypropylene mesh explant from the pelvic wall of rats.

Introduction And Hypothesis: To analyze the immunochemical and urodynamic outcomes after partial versus complete excision of transvaginal polypropylene mesh (PPM) from pelvic walls of rats.

Methods: Forty-eight female Sprague-Dawley (SD) rats were randomly distributed into seven groups: control, mesh total removal 60 days (M-T 60D), mesh total removal 180 days (M-T 180D), mesh partial removal 60 days (M-H 60D), mesh partial removal 180 days (M-H 180D), sham 60 days (Sham 60D), and sham 180 days (Sham 180D). In the mesh groups, PPM was inserted and partially (0.

Immunochemical analysis on polypropylene mesh: does mesh size make a difference?

Introduction And Hypothesis: The aim of the study is to demonstrate the impact of the size of implanted mesh in relation to its immunohistochemical reaction implanted into animal models.

Methods: An experimental study utilizing 54 female Sprague Dawley (SD) rats was divided into five groups: control, sham, and study groups (mesh-small [M-S], mesh-medium [M-M], mesh-large [M-L]). The M-S group used a mesh size of 0.

Dissecting of the paravesical space associated with lower urinary tract dysfunction - a rat model.

To determine the association of opening the paravesical space in relation to its occurrence of de novo SUI in an animal model. Thirty five female Sprague Dawley rats were divided into 5 groups of 7 rats each: Control group, Sham groups(F, H), and Study groups(MF, MH). Groups labeled with "F" had the paravesical space opened, "H" had tissue dissection with no opening of the space, and "M" had mesh implanted inside the vaginal wall.

The immunohistochemical and urodynamic evaluation towards the collagen-coated and non-coated polypropylene meshes implanted in the pelvic wall of the rats.

Our aim is to study the inflammatory response towards the collagen-coated and non-coated polypropylene meshes in rats and the urodynamic investigation post-operatively. Forty-two female Sprague Dawley were divided into 7 groups of 6 rats; Control, Day 7 and 30 for Sham, Avaulta Plus (MPC), Perigee (MP). UDS were taken at days 7 and 30.

Association of urodynamics and lower urogenital tract nerve growth factor after synthetic vaginal mesh implantation on a rat model.

Aim: By investigating the association of urodynamics and urogenital nerve growth factor (NGF) levels in vaginal mesh surgery, we may be able to associate the likelihood of postoperative lower urinary tract symptoms developing as a result of synthetic mesh implanted for pelvic floor reconstructive surgery.

Methods: Thirty-eight female Sprague-Dawley rats were divided into three groups: mesh, sham (no mesh), and control. Urodynamic study and NGF analysis of the urogenital tissues were done and results were compared among all groups.

Effect of suburethral prolene mesh for suburethral function and histology in a stress urinary incontinence mouse model.

Objectives: To create a mouse model pertaining to mesh-elicited suburethral functional and histological changes after vaginal distention, and to examine the possible mechanism behind these complications.

Methods: We divided 48 virgin female C57BL/6 mice into four groups: vaginal distention alone, vaginal distention followed by prolene mesh implantation, vaginal distention followed by sham mesh implantation and untreated control. Each group was divided into two subgroups for conscious cystometrogram, leak-point pressure testing and harvesting of suburethral tissue 4 or 10 days after vaginal distention.

Reciprocal regulation of microRNA-99a and insulin-like growth factor I receptor signaling in oral squamous cell carcinoma cells.

Background: MicroRNAs (miRNAs), small noncoding RNA molecules can function as oncogenes or tumor suppressors in tumorigenesis. Oral squamous cell carcinoma (OSCC) is one of the most prevalent cancers worldwide with a 5-year survival rate of approximately 50%.

Methods: The expression of microRNA-99a (miR-99a) in OSCC tissues and cell lines was investigated using quantitative reverse transcription-polymerase chain reaction (qRT-PCR) analysis.

Differentiated epithelial- and mesenchymal-like phenotypes in subcutaneous mouse xenografts using diffusion weighted-magnetic resonance imaging.

Epithelial-mesenchymal transition (EMT) is important for tumor metastasis. Detection of EMT protein expression and observation of morphological changes are commonly used to identify EMT. Diffusion-weighted magnetic resonance imaging (DW-MRI) and measuring apparent diffusion coefficient (ADC) values are noninvasive techniques for characterizing tumor microenvironments.

p16 Stimulates CDC42-dependent migration of hepatocellular carcinoma cells.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths worldwide. Tumor dissemination to the extra-hepatic region of the portal vein, lymph nodes, lungs or bones contributes to the high mortality seen in HCC; yet, the molecular mechanisms responsible for HCC metastasis remain unclear. Prior studies have suggested a potential link between accumulated cytoplasm-localized p16 and tumor progression.

Krüppel-like factor 4, a tumor suppressor in hepatocellular carcinoma cells reverts epithelial mesenchymal transition by suppressing slug expression.

Krüppel-like factor 4 (KLF4) is a zinc-finger transcription factor that plays an important role in differentiation and pathogenesis. KLF4 has been suggested to act as an oncogene or tumor suppressor in different tumor types. However, the role of KLF4 in hepatocellular carcinoma (HCC) remains unclear.
