Article Abstract

Among cancers, liver cancer is the fourth leading cause of mortality worldwide and drawbacks of conventional approaches could not inhibit this cancer. Thus, an efficient folic acid (FA)-functionalized chitosan (CS)-poly lactic-co-glycolic acid (PLGA) nanocarrier was fabricated for delivery of sodium butyrate (NB) therapeutics to HepG2 liver cancer cells. The fabricated CS-NB-PLGA-FA nanocarrier was characterized by FT-IR, DLS, TEM, and TGA. A size range of 45 nm to 80 nm, surface charge of 4.2 mV, and drug encapsulation of 15.17% were measured for nanocarrier. Controlled (about fivefolds within 2 h) and pH-sensitive drug release manner observed in PBS as well. The MTT assay indicated that CS-NB-PLGA-FA resulted in about 13% cell viability after 24 h of treatment with 400 nM concentrations (IC: 300 nM). The qRT-PCR technique revealed nearly a 7.9- and 5.8-fold increase for Caspase9 and Bax genes while a decrease of about fivefold for the Bcl2 gene after treatment with CS-NB-PLGA-FA. Additionally, about 60% apoptosis was observed for the cells treated with nanocarrier. Remarkable enhancement did indicate for ROS (increase in the catalase and SOD units). These data have demonstrated that CS-NB-PLGA-FA could be a promising candidate against liver cancer.

Background: Alcohol consumption is a risk factor for certain cancers and is increasing in the United States. We estimated the impact of alcohol consumption on cancer incidence trends in the United States from 2008-2019 across six alcohol-related cancers among men and women.

Methods: Average daily alcohol consumption (ADC) was calculated from the National Health Interview Survey (NHIS, 1998-2009) and adjusted to per capita sales data to account for underreporting alcohol use.

Acute or chronic liver damage can result in Hepatic Encephalopathy (HE), a potentially fatal neuropsychiatric condition that leads to cerebral and neurological alterations. Dapagliflozin (DAPA), an orally active Sodium/Glucose cotransporter 2 inhibitor with long duration of action. The study aim was to evaluate the potential protective impact of DAPA against HE caused by Thioacetamide (TAA) in rats.

Background: The suppressor of tumorigenesis 2 (ST2) has emerged as one of the most promising biomarkers for predicting mortality of acute graft-versus-host disease (aGvHD) when measured at the onset of symptoms, but detailed time course studies are needed to understand the potential of ST2 as a risk marker of both aGvHD and chronic graft-versus-host disease (cGvHD), potentially allowing pre-emptive adjustment of immunosuppressive treatment.

Procedure: We measured ST2 levels in 117 children undergoing standard hematopoietic stem cell transplantation (HSCT) before conditioning and at regular intervals post-HSCT.

Results: ST2 levels were significantly increased from Day +7 in patients developing aGvHD of any grade (no GvHD: 23.

Background: The Middle East and North Africa (MENA) region is undergoing demographic shifts potentially increasing metabolic dysfunction-associated steatotic liver disease (MASLD) and its complications. We assessed MASLD prevalence and liver disease burden from 2010 to 2021.

Methods: Data from Global Burden of Disease (GBD), United Nations Population Division and NCD Risk Factor Collaboration covering 21 MENA countries were used for annual percent change (APC) trends per Joinpoint regression.

Background: Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths, primarily due to late-stage diagnosis. In this multicenter study, our goal is to identify functional biomarkers that stratify the risk of HCC in patients with cirrhosis (CP) for early diagnosis.

Methods: Five thousand and eight serum proteins (Somascan) were analysed in Cohort A (477 CP, including 125 HCC).
