Effect of the addition of antifreeze protein type I on the quality of post-thawed domestic cat epididymal sperm.

Cryopreservation of domestic cat semen is mainly performed as a model for the establishment of endangered wild feline protocols. The supplementation of antifreeze protein type I (AFP I) to cryopreservation medium has shown improvement in frozen-thawed sperm quality in other species, but its effect on cat semen has not yet been tested. This study aimed to assess the addition of AFP I to cryopreservation medium in domestic cats.

Fluorescein-Guided Surgery for Malignant Gliomas.

Fluorescein (FS) was first used to visualize malignant brain tumors in 1948. FS accumulates in malignant gliomas where the blood-brain barrier is disrupted and provides intraoperative visualization that is similar to preoperative contrast-enhanced T1 images in which gadolinium accumulation is seen. FS can be viewed under white light, but the use of an operating microscope fitted with a dedicated filter (YELLOW 560 nm Filter, Carl Zeiss Meditec, Oberkochen, Germany) allows us to significantly reduce the dose needed to highlight tumoral tissue.

Assembling the layers of the hematopoietic system: A window of opportunity for thymopoiesis in the embryo.

During embryonic development, several independent generations of hematopoietic cells were identified. They occur in the yolk sac and the intra-embryonic major arteries, in a narrow window of development. They arise sequentially, starting with primitive erythrocytes in the yolk sac blood islands, progressing to less differentiated erythromyeloid progenitors still in the yolk sac, and culminating with multipotent progenitors, some of which will generate the adult hematopoietic stem cell compartment.

A Near InfraRed Emissive Chemosensor for Zn and Phosphate Derivatives Based on a Di-(2-picolyl)amine-styrylflavylium Push-Pull Fluorophore.

A new Near InfraRed (NIR) fluorescent chemosensor for metal ions and anions is herein presented. The fluorophore is based on a styrylflavylium dye, a synthetic analogue of the natural anthocyanin family, with a di-(2-picolyl)amine (DPA) moiety as the metal chelating unit. The substitution pattern of the styrylflavylium core (with tertiary amines on positions 7 and 4') shifts the optical properties of the dye towards the NIR region of the electronic spectra, due to a strong push-pull character over the π-conjugated system.
