The FKBP51s Splice Isoform Predicts Unfavorable Prognosis in Patients with Glioblastoma.

Unlabelled: The primary treatment for glioblastoma (GBM) is removing the tumor mass as defined by MRI. However, MRI has limited diagnostic and predictive value. Tumor-associated macrophages (TAM) are abundant in GBM tumor microenvironment (TME) and are found in peripheral blood (PB).

Antioxidants into Nopal (), Important Inhibitors of Free Radicals' Formation.

Nopal () belonging to the Cactacea family has many nutritional benefits attributed to a wide variety of phenolic and flavonoid compounds. Coumaric acid (COA), ferulic acid (FLA), protocatechuic acid (PRA), and gallic acid (GAA) are the phenolic acids (PhAs) present in nopal. In this study, the role of these PhAs in copper-induced oxidative stress was investigated using the density functional theory (DFT).

Hafnium vs. Zirconium, the Perpetual Battle for Supremacy in Catalytic Olefin Polymerization: A Simple Matter of Electrophilicity?

The performance of -symmetric -hafnocene catalysts for isotactic polypropylene typically deteriorates at increasing temperature much faster than that of their zirconium analogues. Herein, we analyze in detail a set of five Hf/Zr metallocene pairs-including some of the latest generation catalysts-at medium- to high-polymerization temperature. Quantitative structure-activity relationship (QSAR) models for stereoselectivity, the ratio allyl/vinyl chain ends, and 2,1/3,1 misinsertions in the polymer indicate a strong dependence of polymerization performance on electrophilicity of the catalyst, which is a function of the ligand framework and the metal center.

Antiplatelet Therapy for Non-ST-Segment Elevation Myocardial Infarction in Complex "Real" Clinical Scenarios: A Consensus Document of the "Campania NSTEMI Study Group".

The incidence of ST-segment elevation myocardial infarction (STEMI) has significantly decreased. Conversely, the rate of non-STEMI (NSTEMI) has increased. Patients with NSTEMI have lower short-term mortality compared to patients with STEMI, whereas at long-term follow-up, the mortality becomes comparable.

[Non-surgical treatment of pseudoaneurysm of the hepatic artery and its branches].

The transcatheter embolization of hepatic artery pseudoaneurysms and of its branches is now considered the most effective tool for their treatment. These lesions are caused by abdominal traumas or inappropriate surgical treatment. These pseudoaneurysms must be treated promptly because they are at high risk for rupture, with subsequent complications such as hematemesis, hemobilia and hemoperitoneum.

Immunohistochemical demonstration of the presence and localization of diverse molecular forms of gonadotropin-releasing hormone in the lizard (Podarcis s. sicula) brain.

The immunohistochemical presence and the distribution pattern of four different molecular forms of gonadotropin-releasing hormone (GnRH) were investigated in the brain of both sexes of the lizard, Podarcis s. sicula. Animals used in this study were collected in November and April, representing two different periods of the reproductive cycle.

Characterization of four tyrosine protein kinases from the particulate fraction of rat spleen.

Four distinct tyrosine protein kinases active on poly(Glu4,Tyr1) and angiotensin II, and operationally termed TPK-I, TPK-IIA, TPK-IIB and TPK-III have been resolved and partially purified from rat spleen particulate fraction by combining DEAE-Sepharose, heparin-Sepharose, phosphocellulose and polylysine-agarose chromatographies. Once partially purified all of them are free of Ser/Thr-specific protein kinase activity as judged using casein, histones, protamine and the peptide Arg-Arg-Ala-Ser-Val-Ala as substrates. TPK-I (apparent molecular mass 64 kDa, by gel filtration) and TPK-IIA (54 kDa) share several properties, including substrate specificity and stimulation by heparin; the latter however is much more responsive to polylysine then the former (10- and 3-fold maximum stimulation, respectively).
