Clinicopathological features and management of biliary cystic tumors of the liver: a single-center experience.

Background: Biliary cystic neoplasms (BCNs) of the liver are rare pathologies encountered in hepatobiliary surgeries. Till now, there is a lack of definitive criteria used to differentiate biliary cystadenoma (BCA) from biliary cystadenocarcinoma (BCAC).

Methods: In the period between 2005 and 2018, the data of consecutive patients diagnosed with BCA and BCAC were retrospectively reviewed.

Infection in Cirrhotic Patients With Portal Hypertensive Gastropathy: A New Enigma?

The relationship between () infection and Portal hypertensive gastropathy (PHG) is still a debatable matter. The aim of this study is to find out how common infection is in cirrhotic patients with PHG and to see if there's a link between infection and PHG severity. Out of 340 cirrhotic patients who had upper Gastrointestinal Tract (GIT) endoscopy for early varices screening, 160 cirrhotic patients were selected and divided into 2 groups; 80 cirrhotic patients with PHG (cases) and 80 cirrhotic patients without PHG (controls).

Beneficial effect of trimetazidine on folic acid-induced acute kidney injury in mice: Role of HIF-1α/HO-1.

Acute kidney injury (AKI) is a complex syndrome associated with a decrease in renal function and a significant impact on patient outcomes. Injection of folic acid (FA) in mice is used for studying the pathogenesis of AKI. This study investigated the impact of trimetazidine (a metabolic modulator-antianginal drug; TMZ), against FA-induced AKI.

Immunohistochemical expression of FOXP3 in gastric carcinoma; its relation to Ki-67 proliferation marker, HER2/neu expression, and other clinicopathological parameters.

Gastric cancer is common cancer in the world. Contradictory results regarding FOXP3 expression in gastric carcinoma were detected and the role of Ki-67 in prognosis is not completely understood. Furthermore, due to increasing use of anti-HER2 drug trastuzumab for gastric cancer, assessment of HER2 expression becomes important.

Gastrointestinal and hepatic diseases during the COVID-19 pandemic: Manifestations, mechanism and management.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is considered the causative pathogen of coronavirus disease 2019 (COVID-19) and has become an international danger to human health. Although respiratory transmission and symptoms are still the essential manifestations of COVID-19, the digestive system could be an unconventional or supplementary route for COVID-19 to be transmitted and manifested, most likely due to the presence of angiotensin-converting enzyme 2 (ACE2) in the gastrointestinal tract. In addition, SARS-CoV-2 can trigger hepatic injury direct binding to the ACE2 receptor in cholangiocytes, antibody-dependent enhancement of infection, systemic inflammatory response syndrome, inflammatory cytokine storms, ischemia/reperfusion injury, and adverse events of treatment drugs.

Copy Number Profiles of Prostate Cancer in Men of Middle Eastern Ancestry.

Our knowledge of prostate cancer (PCa) genomics mainly reflects European (EUR) and Asian (ASN) populations. Our understanding of the influence of Middle Eastern (ME) and African (AFR) ancestry on the mutational profiles of prostate cancer is limited. To characterize genomic differences between ME, EUR, ASN, and AFR ancestry, fluorescent in situ hybridization (FISH) studies for deletion and MYC amplification were carried out on 42 tumors arising in individuals of ME ancestry.

Molecular characterization of prostate cancer in Middle Eastern population highlights differences with Western populations with prognostic implication.

Background: To investigate the incidence and prognostication of ERG, PTEN and SPINK1 protein expressions in prostate cancer cohort of Middle Eastern descent in comparison to published data from Western population.

Methods: Immunohistochemistry for ERG, PTEN and SPINK1 was performed in a cohort of localized PCA (n = 340). The data were correlated to pathological and clinical outcomes and compared to Western populations.

The course of infection with Toxoplasma gondii RH strain in mice pre-vaccinated with gamma irradiated tachyzoites.

Toxoplasma gondii is a ubiquitous protozoan of major medical and veterinary importance. Its treatment is difficult since the available drugs have severe side effects and reactivation may occur anytime. Vaccination with irradiated parasites exhibits ideal characteristics for vaccine development.
