There are few reports on focal epithelial hyperplasia (FEH) in association with human immunodeficiency virus (HIV) infection; thus the relationship between them has not been completely clarified yet. We present a case of recurrent FEH in an HIV-positive man (the first described in Belgium), which, according to the PCR-DNA testing, was due to human papilloma virus type 13 (HPV13). To our knowledge, based on the accessible literature, this type of HPV has not been detected in any other documented study of FEH in HIV-positive patients before. Our patient experienced three recurrences of FEH in 1 year. It is therefore suggested that immunodeficiency due to HIV infection is responsible for the HPV-related FEH and the subsequent recurrences. In order to support the consideration of FEH as an oral manifestation of an HIV-related opportunistic infection, every new 'HPV-type' oral lesion in HIV-positive patients must be completely documented.

The RNase activity of MCPIP1 is essential for regulating cellular homeostasis, proliferation, and tumorigenesis. Our study elucidates the effects of downregulation of MCPIP1 expression and an RNase-inactivating mutation (D141N) on normal epithelial kidney cells, indicating that MCPIP1 expression is a key factor that suppresses neoplastic transformation. We observed that either expression downregulation or mutation of MCPIP1 significantly increased its clonogenicity and altered the expression of cancer stem cell (CSC) markers and factors involved in epithelial-to-mesenchymal transition (EMT).

The absence of a clear consensus on the definition and significance of fascia and the indiscriminate use of the term throughout the clinical and scientific literature has led to skepticism regarding its importance in the human body. To address this challenge, we propose that: (1) fasciae, and the fascial interstitia within them, constitute an anatomical system, defined as a layered body-wide multiscale network of connective tissue that allows tensional loading and shearing mobility along its interfaces; (2) the fascial system comprises four anatomical organs: the superficial fascia, musculoskeletal (deep) fascia, visceral fascia, and neural fascia; (3) these organs are further composed of anatomical structures, some of which are eponymous; (4) all these fascial organs and their structural components contain variable combinations and arrangements of the four classically defined tissues: epithelial, connective, muscle, and neural; (5) the overarching functions of the fascial system arise from the contrasting biomechanical properties of the two basic types of layers distributed throughout the system: one predominantly collagenous and relatively stiff, the other rich in hyaluronic acid and viscous, allowing for the free flow of fluid; (6) the topographical organization of these layers in different locations is related to local variations in function (e.g.

Objectives: Depth of invasion (DOI) in oral squamous cell carcinoma (OSCC) guides treatment and prognosis but lacks three-dimensional (3D) insight. Thus, this study aimed to investigate the feasibility and accuracy of Lugol's iodine-enhanced micro-computed tomography (CT) for the 3D measurement of DOI in OSCC samples.
Methodology: In total, 50 in vitro OSCC samples from Nanjing Stomatological Hospital (July 2022 to January 2024) were subjected to micro-CT imaging with a slice thickness of 50 μm following 3% Lugol iodine staining for 12 h, followed by pathological examination and staining.

Purpose Of Review: The role of the lymphatic system in clearing extravasated fluids, lipid transport, and immune surveillance is well established, and lymphatic vasculature can provide a vital role in facilitating crosstalk among various organ systems. Lymphatic vessels rely on intrinsic and local factors to absorb and propel lymph from the interstitium back to the systemic circulation. The biological implications of local influences on lymphatic vessels are underscored by the exquisite sensitivity of these vessels to environmental stimuli.

Background: Regulator of G protein signaling (RGS) proteins participate in tumor formation and metastasis by acting on the α-subunit of heterotrimeric G proteins. The specific effect of RGS, particularly , on the progression of gastric cancer (GC) is not yet clear.
Aim: To explore the role and underlying mechanisms of action of in GC development.
