An intimate collaboration between peroxisomes and lipid bodies.

Although peroxisomes oxidize lipids, the metabolism of lipid bodies and peroxisomes is thought to be largely uncoupled from one another. In this study, using oleic acid-cultured Saccharomyces cerevisiae as a model system, we provide evidence that lipid bodies and peroxisomes have a close physiological relationship. Peroxisomes adhere stably to lipid bodies, and they can even extend processes into lipid body cores.

[Evaluation of topical anesthesia with sedation in cataract surgery].

Purpose: Evaluation of comfort and safety of patent and surgeon during the cataract surgery under topical anesthesia with sedation.

Material And Methods: 106 consecutive patients operated on in the period of two months without previous selection, were evaluated. Cataract surgery was performed in all patients with phacoemulsification in one-day surgery.

[Simultaneous cataract and glaucoma surgery. Selection of trabeculectomy site].

Purpose: Analysis of the results of simultaneous surgery using phacotrabeculectomy technique and standard phacoemulsification and trabeculectomy from two separate incisions.

Material And Methods: Analyzed group included 41 patients /44 eyes/, aged 68 +/-18 years with combined glaucoma and cataract. In 28 operated eyeballs phacotrabeculectomy from single incision was performed and in 19 operated eyeballs phacotrabeculectomy and phacoemulsification from two separate incisions was used.

ACT-5 is an essential Caenorhabditis elegans actin required for intestinal microvilli formation.

Investigation of Caenorhabditis elegans act-5 gene function revealed that intestinal microvillus formation requires a specific actin isoform. ACT-5 is the most diverged of the five C. elegans actins, sharing only 93% identity with the other four.
