Article Abstract
The aim of this study was to detect the expression of β-AR (Beta Adregenic Receptor) in Oral squamous cell carcinoma (OSCC), para-cancerous and normal oral mucosa and to investigate the relationship between the expression intensity and the characteristics and prognosis of oral cancer. 100 cases of OSCC were collected; 20 cases of paraneoplastic tissues and 10 cases of normal oral mucosa were taken as control. The expression of β-AR was detected by immunohistochemical method and the average optical density determination using Image J software. Finally, the difference of β-AR expression and the correlation with the clinicopathological factors were analyzed statistically. The expression of β-AR in OSCC was higher than that in paracarcinoma and normal mucosa (P<0.01). The expression intensity of β1, β2-AR in preoperative lymph node metastasis group was higher than that in patients without lymph node metastasis (P<0.01). The expression intensity of β3-AR was not related to pathological grade and tumor size (P>0.05). β1 and β2-AR in early stage of OSCC were higher than those in early stage (P<0.05). Lymph node metastasis, recurrence, TNM clinical stage, and the expression intensity of β1-AR all had an effect on the cumulative survival rate. All the β1, 2, 3-AR were expressed in OSCC. β1 and β2-AR were involved in lymphatic metastasis and had influence on clinical staging. Metastasis, recurrence, TNM stage and expression of β1-AR had an effect on the cumulative survival rate of tumor. The expression of β3-AR in OSCC was not associated with the pathological grades and tumor growth.

Mesenchymal stem cells (MSCs) are promising candidates for regenerative therapies due to their self-renewal and differentiation capabilities. Pathological microenvironments expose MSCs to senescence-inducing factors such as reactive oxygen species (ROS), resulting in MSC functional decline and loss of stemness. Oxidative stress leads to mitochondrial dysfunction, a hallmark of senescence, and is prevalent in aging tissues characterized by elevated ROS levels.

Purpose: Individual-level state-transition microsimulations (iSTMs) have proliferated for economic evaluations in place of cohort state transition models (cSTMs). Probabilistic economic evaluations quantify decision uncertainty and value of information (VOI). Previous studies show that iSTMs provide unbiased estimates of expected incremental net monetary benefits (EINMB), but statistical properties of iSTM-produced estimates of decision uncertainty and VOI remain uncharacterized.

It is now understood that brain metastases do not occur randomly but have distinct spatial patterns depending on the origin of the cancer. According to the "seed and soil" hypothesis, the final colonization of metastatic cells is the result of their adaptation to the altered environment. To investigate the most favorable microenvironment for brain metastasis, we analyzed neuroimaging data from 177 patients with breast cancer brain metastasis and 548 patients with lung cancer brain metastasis to create a replicable probabilistic map of metastatic locations.

Background: Asthma is a global chronic respiratory disease with complex pathogenesis. While current therapies offer some relief, they often fall short in effectively managing symptoms and preventing exacerbations for numerous patients. Thus, understanding its mechanisms and discovering new drug targets remains a pressing need for better treatment.
