DNA-Dependent Protein Kinase Inhibitor Peposertib Enhances Efficacy of Lu-Based Radioimmunotherapy in Preclinical Models of Prostate and Renal Cell Carcinoma.

Novel radiation sensitizers, including inhibitors targeting DNA damage response, have been developed to enhance the efficacy of anticancer treatments that induce DNA damage in cancer cells. Peposertib, a potent, selective, and orally administered inhibitor of DNA-dependent protein kinase, impedes the nonhomologous end-joining mechanism for DNA double-strand break (DSB) repair. We investigated radioimmunotherapy alone or with peposertib in preclinical models of renal cell carcinoma (RCC) or prostate cancer.

In response to the changing intertidal environment, intertidal macroalgae have evolved complicated Ci utilization mechanisms. However, our knowledge regarding the CO concentrating mechanism (CCM) of macroalgae is limited. Carbonic anhydrase (CA), a key component of CCM, plays essential roles in many physiological reactions in various organisms.

Optical characterization of dissolved organic carbon (DOC) freshly collected from the circumneutral "white water" of the Rio Solimoes revealed that it had lower aromaticity, lower molecular weight, and a greater autochthonous content than DOC from the acidic "black water" of the Rio Negro. The tambaqui (Colossoma macropomum), a characid member of the Serrasalmidae, is a model neotropical fish that migrates annually between the two rivers. We analysed ionoregulatory responses of the tambaqui over 24 h in ion-poor water at pH 7.

Here, we describe a rare case of drug-induced unilateral ciliary body effusion precipitated by topical brinzolamide, presenting acutely with pain, angle closure and myopic shift.Ciliary body effusion was suspected clinically and confirmed by ultrasound biomicroscopy. Brinzolamide was ceased, atropine instilled and the ciliary body effusion promptly resolved without need for further treatment.

The sequestration of carbon dioxide using carbonic anhydrase (CA) is one of the most effective methods for mitigating global warming. The burning of fossil fuels releases large quantities of flue gas; because of its high temperature and of the alkaline conditions required for CaCO precipitation in the mineralization process, thermo-alkali-stable CAs are needed. In this context, Manyumwa et al.
