In this study we investigated the expression of insulin-like growth factor II (IGf-II) to explain a role for this growth factor in concert with hepatitis B virus (HBV) involvement in the development of hepatocellular carcinoma (HCC) from chronic hepatitis type B (CAH-B) and liver cirrhosis (LC). The expressions of IGF-II and HBsAg were tested in tissue samples from 38 patients with CAH-B, 32 with LC, and 31 with HCC, by immunohistochemical staining using monoclonal anti IGF-II and anti HBs. All patients were seropositive for the presence of HBsAg. The expression of IGF-II was observed in 30 out of 32 (93.8%) LC and all 31 (100%) HCC tissue samples tested. IGF-II was expressed in most hepatocytes of regenerating nodules and in tumorous as well as nontumorous cells of HCC tissues. Neither normal liver tissues nor CAH-B tissue samples expressed IGF-II. HBsAg was expressed in 34 out of 38 (89.5%) CAH-B, 24 out of 32 (75%) LC and 13 out of 31 (41.9%) HCC tissue samples. The expression sites of HBsAg were not correlated with those of IGF-II in any tissue samples tested. The present study indicates that IGF-II plays a role in cell proliferation of regenerating nodules as well as in the development of hepatocellular carcinomas. In addition, there was no direct evidence of HBV involvement in the overexpression of this growth factor.

Background: Angiogenesis, the formation of new blood vessels from preexisting ones via capillary sprouting, is a crucial process in tumor growth and metastasis. As a tumor's angiogenic capacity increases, its microvasculature, measured by micro vessel density (MVD), also increases. This study aims to evaluate the expression of Vascular Endothelial Growth Factor (VEGF) and CD34 in oral epithelial dysplasia and oral squamous cell carcinoma through immunohistochemical methods.

Background: Oral cancer screening programs can aid in the early identification of potentially malignant oral lesions. The objective of the present study was to evaluate the effectiveness of the Oral Rub and Rinse (ORR) technique as an oral cancer screening tool and to test its potential in detecting genetic alterations in exfoliated cells obtained through ORR.
Methods: The screening programs were conducted in rural Dakshina Kannada and Udupi districts in Karnataka.

The Warburg effect, a common feature of solid tumors, rewires the metabolism and promotes growth, survival, proliferation, and long-term maintenance in gastric cancer (GC). We performed in vitro and in vivo studies of the pathogenesis of GC to investigate the effects and mechanism of LINC01224 in this cancer. qRT-PCR was used to measure the expression of LINC01224 or miR-486-5p in GC cells, and the expression of LINC01224 in GC tissues by FISH (Fluorescence in situ hybridization) analysis was evaluated.

Although the role of low-level laser therapy (LLLT) and human adipose-derived stem cells (hADSC) in accelerating diabetic wound healing has been proven, their synergistic effect is still debated. This study aimed to evaluate the individual and combined effects of LLLT and hADSC on wound healing and on biomechanical parameters in type 2 diabetic rabbits. In this experimental study, 40 rabbits with type 2 diabetes (induced by streptozotocin (STZ)) were included.
