Results of complex treatment of patients with operable pancreatic head cancer using preoperative intra-arterial chemotherapy in combination with radiation therapy in multifractionation mode

The aim of this study was to assess the safety and efficacy of treating patients with operable pancreatic cancer after preoperative intra-arterial infusion of chemotherapy combined with conformal radiation therapy in a multi-fractionation mode. Patients (n = 40) were randomized into two groups: the main one – intra-arterial infusion of chemotherapy + radiation therapy + surgery (n = 20), and control – intra-arterial infusion of chemotherapy + surgery (n = 20). Neoadjuvant therapy consisted of intra-arterial infusion of chemotherapy (chemoembolization of a pancreatic head tumor with oxaliplatin 85 mg/m2) followed by intra-arterial chemo infusion with gemcitabine 1000 mg/m2. In the main group, radiation therapy was also carried out in two fractions per day, 2 Gy with an interval of 4–6 hours, 5 days a week, up to a total dose of 50 Gy. In the main group, the lower incidence of postoperative pancreatitis and the pancreatic fistulas were statistically confirmed, the incidence of grade 2 therapeutic pathomorphisis increased, as well as the median life expectancy.

P-block tin single atom catalyst for improved electrochemistry in lithium-sulfur battery: a theoretical and experimental study

Main group metals are routinely considered as catalytically inactive hence never employed for optimizing the lithium-sulfur electrochemistry. Herein, density function theory calculations reveal that atomically dispersed tin on nitrogen doped...

Geminal C–Cl and Si–Cl Bond Activation of Chloromethanes and Chlorosilanes by Gallanediyl LGa

The activation of relatively inert E-X σ-bonds by low-valent main group metal complexes is receiving increasing interest. We here confirm the promising potential of gallanediyl LGa (L = HC[C(Me)N(Dip)]2, Dip...

Base-stabilized formally zero-valent mono and diatomic molecular main group compounds

Various compounds are known for transition metals in their formal zero oxidation state, while similar compounds of main-group elements are recently realized and limited to only a few examples. Lewis...
