A systematic study on the characteristics and applications of laccases produced by fungi: insights on their potential for biotechnologies.

Laccases are polyphenol oxidase enzymes and form the enzyme complex known for their role in wood decomposition and lignin degradation. The present study aimed to systematically review the state-of-the-art trends in scientific publications on laccase enzymes of the last 10 years. The main aspects checked included the laccase-producing fungal genera, the conditions of fungal growth and laccase production, the methods of immobilization, and potential applications of laccase.

How deadly sarcophagid fly larvae are for anurans? New interactions and review to Neotropical region.

Myiasis is defined as the infestation of living or necrotic tissues of vertebrates by dipteran larvae. In amphibians, it can be caused by fly larvae belonging to families Calliphoridae, Chloropidae, Muscidae, and Sarcophagidae. In this study, we report new records and infestation intensity of myiasis in anurans from two localities of the Atlantic Forest in southern Brazil, and also present a list with myiasis caused by flesh fly Sarcophagidae species in anurans of the Neotropical region.

Synthesis of new 1-phenyl-3-{4-[(2E)-3-phenylprop-2-enoyl]phenyl}-thiourea and urea derivatives with anti-nociceptive activity.

Chalcones or 1,3-diaryl-2-propen-1-ones are known to be useful for treating pain, inflammation, and certain diseases although their uses have not been scientifically verified. Due to the limitations of opioid and NSAID therapy, there is a continuing search for new analgesics. A series of novel new 1-phenyl-3-{4-[(2E)-3-phenylprop-2-enoyl]phenyl}-thiourea and urea derivatives were synthesized and evaluated against writhing test in mice, following the aromatic substitution pattern proposed by Topliss.

[Study about the feasibility of ovarian graft in rats' omentum pouch, using Cyclosporine A].

Purpose: To study comparatively ovarian autograft and heterograft in rats' omentum pouch, using Cyclosporine A.

Methods: In the present study 20 rats, distributed equally in four groups, had been used: Control Group (rats submitted to ooforectomy); Group A (ovarian autograft); group H (ovarian heterograft); e group C (ovarian heterograft and treatment with Cyclosporine A). All animals had been submitted to a bilateral ooforectomy.
