A sediment sample was obtained at 122 cm from the top of a drilling core in the Guapimirim mangrove, Bay of Guanabara, and analyzed using pollen analysis. This muddy core reached a sandy ground at 133 cm. 14C datation got the age of 1760 +/- 50 years B.P. The most frequent pollen grains were mangrove species of Rhizophora mangle, Laguncularia racemosa and Avicennia schaueriana. "Restinga" and t...

Growing incidences of β-lactamase producing uropathogens have been observed worldwide. Extended Spectrum β-lactamase (ESBLs) and Metallo β-lactamase (MBLs) are two types of β-lactamases that have emerged as a major threat with limited treatment options. In the current study, the effect of Avicennia marina leaf and stem extracts was studied on 10 ESBL and 10 MBL producing uropathogens which were...

L.] populations on the south Texas Gulf Coast...

OBJECTIVE(S) Regarding the presence of many active biological constituents in Avicennia marina, the present investigation was carried out to study cytotoxic activity of crude methanol leave extract and column chromatographic fractions of A. marina against MDA-MB 231 cell line (human breast cancer cell) and HEK (Human embryonic kidney cell) line. MATERIALS AND METHODS The anticancer activity o...

Adaptive management of natural resources is an iterative process of decision making whereby management strategies are progressively changed or adjusted in response to new information. Despite an increasing focus on the need for adaptive conservation strategies, there remain few applied examples. We describe the 9-year process of adaptive comanagement of a marine protected area network in Kubula...

Avicennia marina (Avicenniaceae) is a species of mangrove tree used for treatment of small pox lesions in Persian folk medicine. The antiviral activity of methanol, ethanol, water, chloroform and n-hexane extracts was evaluated against HIV-1 and HSV. Methanol extract had the highest antiviral activity and the most polar fraction of this extract (fraction D) inhibited HSV with TI and SI values o...
