Prognostic Significance of C-MYC and EGFR Overexpression in Gastrointestinal Stromal Tumors: An Immunohistochemical Study.

Introduction: In addition to mutations in KIT and PDGFRA, many other genetic alterations have been described in gastrointestinal stromal tumors (GISTs), including amplifications of C-MYC and EGFR, which are often associated with increased protein expression. The main of this study was to investigate the prognostic significance of C-MYC and EGFR expression in GISTs using immunohistochemistry (IHC).

Methods: We collected all GIST cases over a 16-year period.

Diagnostic and therapeutic challenges of a rare large ovarian strumal carcinoid in pregnancy, about a case report.

Introduction: Ovarian strumal carcinoid is a rare type of germ cell tumor. It usually affects perimenopausal and postmenopausal women. Very few cases of stromal carcinoid have been reported in the literature in women of childbearing age, particularly during pregnancy.

Primary tuberculosis of the glans penis: A rare presentation and review of literature.

Tuberculosis poses a real public health problem inTunisia.We report an 80-year old patient, immunocompetent, who has initial presentation of a painless ulcerative lesions of the glans penis. A history of pulmonary tuberculosis was not present.

Beyond the Lactate Paradox: How Lactate and Acidity Impact T Cell Therapies against Cancer.

T cell therapies, including CAR T cells, have proven more effective in hematologic malignancies than solid tumors, where the local metabolic environment is distinctly immunosuppressive. In particular, the acidic and hypoxic features of the tumor microenvironment (TME) present a unique challenge for T cells. Local metabolism is an important consideration for activated T cells as they undergo bursts of migration, proliferation and differentiation in hostile soil.

Intrahepatic cholangiocarcinoma mimicking a liver abscess.

Intrahepatic cholangiocarcinoma masquerading as liver abscess, and presenting with fever, is a very rare situation and should be considered in nonresolving liver abscess. Only few cases were reported in the literature. This entity is characterized by late diagnosis and poor prognosis.

Hepatocellular carcinoma arising from hepatic adenoma in a young woman.

Hepatocellular carcinoma (HCC) arising from hepatic adenoma is an infrequent situation. Only a few cases were reported in the literature. We present a rare case of hepatocellular carcinoma arising from HA in a young woman with no medication history of oral contraceptives.

Enhancing Chimeric Antigen Receptor T Cell Anti-tumor Function through Advanced Media Design.

Effective chimeric antigen receptor (CAR)-T cell therapy is dependent on optimal cell culture methods conducive to the activation and expansion of T cells , as well as infection with CAR. Media formulations used in CAR-T cell manufacturing have not been optimized for gene delivery, cell expansion, and overall potency. Bioactive components and derivatives that support the generation of functionally-competent T cell progeny with long-lasting persistence are largely undefined.

Influenza infection rewires energy metabolism and induces browning features in adipose cells and tissues.

Like all obligate intracellular pathogens, influenza A virus (IAV) reprograms host cell's glucose and lipid metabolism to promote its own replication. However, the impact of influenza infection on white adipose tissue (WAT), a key tissue in the control of systemic energy homeostasis, has not been yet characterized. Here, we show that influenza infection induces alterations in whole-body glucose metabolism that persist long after the virus has been cleared.

A new multiple robot path planning algorithm: dynamic distributed particle swarm optimization.

Multiple robot systems have become a major study concern in the field of robotic research. Their control becomes unreliable and even infeasible if the number of robots increases. In this paper, a new dynamic distributed particle swarm optimization (DPSO) algorithm is proposed for trajectory path planning of multiple robots in order to find collision-free optimal path for each robot in the environment.
