Only a few cases of adenocarcinoma (ACA) metastatic to the female lower genital tract diagnosed on cervicovaginal Pap smear have been reported during the past several decades. Both conventional and liquid based cytology (LBC) have limited sensitivity and specificity in diagnosing metastatic disease and immunocytochemical (ICC) staining may be needed for confirming the diagnosis. We present two cases of metastatic colorectal ACA diagnosed on cervicovaginal ThinPrep (TP) Pap smears, with one confirmed by ICC staining method. Recognition of extra-uterine malignancy in the cervicovaginal cytology specimen is critical for the disease diagnosis, prognosis, and the treatment. ICC staining performed on the residual LBC specimen is an important methodology to confirm the diagnosis.

Breast cancer (BC) with aggressive metastasis is a serious ongoing public health problem among women. Graphene oxide (GO) has an inhibitory effect on the migration rate and metastasis of BC cells, but its various aspects have not yet been explored. This paper aims to research into the effect of GO nanoparticles (GO-Np) on the migratory behavior of MDA-MB-231 as a metastatic human BC cell line.

Article Synopsis
- Tooth extraction often leads to bone loss in the jaw, complicating future dental treatments and aesthetics.
- Purple leaves contain beneficial compounds that may improve bone health, while hydroxyapatite is a biocompatible substance that helps bone growth.
- Combining purple leaf extract with hydroxyapatite significantly boosts key bone-related markers and calcium deposition over time in stem cell studies.
Prediction of HIF-1α expression in endometrial carcinoma by enhanced T weighted angiography and dynamic contrast-enhanced magnetic resonance imaging.

Purpose: To explore the value of quantitative imaging parameters by enhanced T weighted angiography (ESWAN) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) for evaluating the expression of Hypoxia-inducible factor-1α (HIF-1α) in endometrial carcinoma (EC).
Methods: Data from 122 patients with EC confirmed by clinical pathology were retrospectively analyzed. According to the number of positive cells stained with HIF-1α by immunohistochemistry, patients were divided into two groups: 65 cases with high expression of HIF-1α and 57 cases with low expression of HIF-1α.
The rat osteoarthritis bone score for histological pathology relevant to human bone marrow lesions and pain.

Pain Centre Versus Arthritis and Academic Unit of Injury, Recovery and Inflammation Sciences, University of Nottingham, UK.
Objectives: Histological osteochondral characteristics of inflammation, fibrosis, vascularity, cartilage islands, vessels entering cartilage, thickened trabeculae and cysts are associated with bone marrow lesions (BMLs) in human knee osteoarthritis (OA). We identified and developed a method for scoring comparable pathology in two rat OA knee pain models.
Methods: Rats (n = 8-10 per group) were injected with monoiodoacetate (MIA) or saline, or underwent meniscal transection (MNX) or sham surgery.

Background: The complex interactions of the tumor micromilieu may be reflected by diffusion-weighted imaging (DWI) derived from the magnetic resonance imaging (MRI). The present study investigated the association between apparent diffusion coefficient (ADC) values and histopathologic features in uterine cervical cancer.
Methods: In this retrospective study, prebiopsy MRI was used to analyze histogram ADC-parameters.
