“Despite a survival benefit in the first-line treatment of castrate-resistant prostate cancer (CRPC) with docetaxel, the prognosis remains limited. There are increasing options available for patients with CRPC in the second-line setting,

but there is currently little consensus regarding the optimal treatment. There have been numerous phase II and retrospective studies examining second-line options in CRPC, including retreatment with docetaxel, mitoxantrone, cyclophosphamide and carboplatin, which can be associated with meaningful responses in a significant minority of patients. In 2010 three randomized trials were published or presented which demonstrated a survival benefit in the second-line setting. These included cabazitaxel compared with mitoxantrone, sipuleucel-T (immunotherapy) and abiraterone INCB018424 ic50 acetate versus placebo. Ongoing research in the second-line setting of CRPC to optimize treatment QNZ concentration options, with the objectives of survival prolongation, improvement in quality of life and pain management, is still needed.”
“Anterior segment optical coherence tomography (AS-OCT) is an important new noncontact imaging technology that uses a 1310 nm super luminescent

diode. It can be used to assess anterior chamber biometry, corneal thickness, lens thickness, and angle configuration; to visualize pathological processes; to evaluate postsurgical anatomy and posttraumatic eyes; and to image phakic intraocular lenses and intracorneal ring segments. Because it is a noncontact technique, it can also be used intraoperatively, which could be useful during trabeculectomy and after deep anterior lamellar keratoplasty to detect abnormalities in the cornea and interface. A disadvantage of AS-OCT is its inability Mizoribine to penetrate the iris pigment epithelium, which makes it impossible to evaluate the structures behind the iris. The most frequently used devices are time-domain AS-OCT, but new Fourier-domain OCT devices, which have faster image acquisition and higher resolution, are

currently under investigation.”
“Giant magnetostriction of up to 2000 ppm was discovered in the tetragonally distorted ferromagnetic phase of antiperovskite Mn3CuN. This magnetostriction was associated with the rearrangement of thermoelastic martensite variants by the magnetic field, similar to that of Ni2MnGa Heusler alloy. The nitrogen-deficient Mn3CuN0.8 contracts, whereas the stoichiometric Mn3CuN expands, along the field direction. This implies a rotation of the easy axis from the longer a axis in Mn3CuN to the shorter c axis in Mn3CuN0.8. The drastic reduction of the operating magnetic field for magnetostriction in Mn3CuN0.8 suggests a possible supermagnetostriction around the compositional region of direction change in the easy axis.
