Histopathological Characteristics of the Orbicularis Oculi Muscle After Lower Blepharoplasty With or Without Myotomy.

Unlabelled: Lower blepharoplasty is a challenging aesthetic procedure. Despite advances in clinical and neuroanatomical studies related to orbicularis oculi muscle innervation, no study has examined its histopathological aspects in different lower blepharoplasty procedures. This study aimed to assess changes in the pretarsal muscle complex in patients treated with transcutaneous lower blepharoplasty with orbicularis myotomy versus those treated with transconjunctival blepharoplasty without myotomy.

Distinct histomorphology for growth arrest and digitate outgrowth in cultivated Haliclona sp. (Porifera: Demospongiae).

The use of sponges in biotechnological processes is limited by the supply problem, and sponge biomass production is becoming a current topic of research. The distinction between characteristics for growth and growth arrest is also important for environmental monitoring. In this study, we analyze the morphology of the digitate outgrowths from the sponge Haliclona sp.

Evaluation of differential protein expression in Haliclona aquarius and sponge-associated microorganisms under cadmium stress.

A comparative proteomic approach was used to assess differentially expressed proteins in marine sponges after 36 h of exposure to cadmium (Cd). After separation performed by 2-D polyacrylamide gel electrophoresis, 46 protein spots indicated differential expression, and 17 of these proteins were identified by electrospray ionization quadrupole time-of-flight mass spectrometry. From the proteins identified, 76% were attributed to sponge-associated microorganisms (fungi and bacteria), and 24% were attributed to Haliclona aquarius.
