Quantum Mechanics of Gravitational Waves.

For the purpose of analyzing observed phenomena, it has been convenient, and thus far sufficient, to regard gravity as subject to the deterministic principles of classical physics, with the gravitational field obeying Newton's law or Einstein's equations. Here we treat the gravitational field as a quantum field and determine the implications of such treatment for experimental observables. We find that falling bodies in gravity are subject to random fluctuations ("noise") whose characteristics depend on the quantum state of the gravitational field.

Laparoscopic isolated caudate lobe resection.

Previously, isolated caudate lobectomy was rarely performed and the caudate lobe was usually resected along with other segments. Isolated caudate lobe resection is a challenging procedure even for an experienced surgeon. Our aim was to evaluate the feasibility, safety and outcomes of laparoscopic isolated caudate lobectomy and to compare these with the open technique.

Post-splenectomy response in adult patients with immune thrombocytopenic purpura.

Unlabelled: Splenectomy has been the conventional surgical treatment for patients with Immune Thrombocytopenic Purpura (ITP).

Aim: To define response to surgical therapy, pre operative factors influencing outcome and tolerability of surgery in adult patients undergoing splenectomy for ITP.

Method: We analyzed prospectively maintained data of 33 patients who were diagnosed as ITP and underwent splenectomy over the last 10 years.
