Effectiveness of a new approach to minimally invasive surgery in palliative treatment of patients with distal malignant biliary obstruction.

Background: Palliative endoscopic biliary drainage is the primary treatment option for the management of patients with jaundice which results from distal malignant biliary obstruction (DMBO). In this group of patients, decompression of the bile duct (BD) allows for pain reduction, symptom relief, chemotherapy administration, improved quality of life, and increased survival rate. To reduce the unfavorable effects of BD decompression, minimally invasive surgical techniques require continuous improvement.

Infectious Complications of Acute Pancreatitis Is Associated with Peripheral Blood Phagocyte Functional Exhaustion.

Background: Infected pancreatic necrosis is one of the most severe complications of acute pancreatitis (AP). The development of secondary infection doubles the risk of death during the late stage of necrotizing pancreatitis. Phagocytes play a major role in AP pathogenesis, as well as in local and systemic complications of the disease.

C fullerene and its nanocomplexes with anticancer drugs modulate circulating phagocyte functions and dramatically increase ROS generation in transformed monocytes.

Background: C fullerene-based nanoformulations are proposed to have a direct toxic effect on tumor cells. Previous investigations demonstrated that C fullerene used alone or being conjugated with chemotherapeutic agents possesses a potent anticancer activity. The main aim of this study was to investigate the effect of C fullerene and its nanocomplexes with anticancer drugs on human phagocyte metabolic profile in vitro.

Sex-based differences in phagocyte metabolic profile in rats with monosodium glutamate-induced obesity.

The important component of obesity pathogenesis is inflammatory activation of innate immune cells within adipose tissue and in other body locations. Both the course of obesity and innate immune reactivity are characterized by sex-associated differences. The aim of the work was a comparative investigation of metabolic profiles of phagocytes from different locations in male and female rats with MSG-induced obesity.

Complex of C60 Fullerene with Doxorubicin as a Promising Agent in Antitumor Therapy.

The main aim of this work was to evaluate the effect of doxorubicin in complex with C60 fullerene (C60 + Dox) on the growth and metastasis of Lewis lung carcinoma in mice and to perform a primary screening of the potential mechanisms of C60 + Dox complex action. We found that volume of tumor from mice treated with the C60 + Dox complex was 1.4 times less than that in control untreated animals.

Physical activity interferes with the immunomodulatory effect of the antineoplastic drug NSC631570.

Objective: The aim of the work was to evaluate the effect of moderate physical exercise on the response of circulating phagocytes to the antineoplastic drug NSC 631570.

Methods: Eight healthy adult men aged 23 ± 2 years were recruited to participate in the study; NSC 631570 was administered i.v.

Paraneoplastic syndrome in mice bearing high-angiogenic variant of Lewis lung carcinoma: relations with tumor derived VEGF.

Background: It is well-known that tumor exerts nonmetastatic systemic effect on organism caused the development of paraneoplastic syndrome (PNS). Recent findings point to relationships between development of PNS and tumor-derived vascular endothelial growth factor (VEGF).

Aim: Comparative study of PNS manifestations in mice with transplanted two variants of Lewis lung carcinoma with different angiogenic potential.
