Porolithon improcerum (porolithoideae, corallinaceae) and mesophyllum macroblastum (melobesioideae, hapalidiaceae): New records of crustose coralline red algae for the Southwest Atlantic Ocean
(Magnolia Press, 2014)
Here we describe in detail two crustose coralline red algal (CCA) species newly reported for the southern Atlantic:
Porolithon improcerum and Mesophyllum macroblastum. Porolithon improcerum was recorded on the remote ...
The arabidopsis wall associated kinase-like 10 gene encodes a functional guanylyl cyclase and is coexpressed with pathogen defense related genes
(Public Library of Science, 2010)
Second messengers have a key role in linking environmental stimuli to physiological responses. One such messenger, guanosine 3′,5′-cyclic monophosphate (cGMP), has long been known to be an essential signaling molecule in ...
Development of a compendium of local, wild-harvested species used in the informal economy trade, Cape Town, South Africa
(Resilience Alliance, 2012)
Wild harvesting has taken place over millennia in Africa. However urbanization and cash economies have
effectively altered harvesting from being cultural, traditional, and subsistence activities that are part of a rural ...
Quantum dot nanotoxicity investigations using human lung cells and toxor electrochemical enzyme assay methodology
(American Chemical Society, 2017)
Recent studies have suggested that certain
nanomaterials can interfere with optically based cytotoxicity
assays resulting in underestimations of nanomaterial toxicity. As
a result there has been growing interest in the ...
Causes and patterns of morbidity and mortality in Afghanistan: Joint estimation of multiple causes in the neonatal period
(Springer, 2014)
This paper focuses on investigating the leading cause(s) of death and preventable factors in Afghanistan,
using data from verbal autopsies of infant deaths. We are of the view that the presence
of a disease in a person ...
Reconstruction of dark energy and expansion dynamics using Gaussian processes
(IOP Publishing, 2012)
An important issue in cosmology is reconstructing the effective dark energy equation
of state directly from observations. With few physically motivated models, future dark
energy studies cannot only be based on constraining ...
The potential of leucosidea sericea against propionibacterium acnes
(Elsevier, 2014)
The present study reports on the potential of Leucosidea sericea addressing acne vulgaris. Four known compounds namely phytol acetate, triacontanol, phytol and alpha kosin and one new compound namely, (E)-3,7,11,15-tetra ...
Understanding the creek dynamics and environmental characteristics that determine the distribution of mangrove and salt marsh communities at Nahoon Estuary
(Elsevier, 2016)
The southern distributional limit for mangroves on the east coast of Africa is thought to be at the planted
mangrove forest at Nahoon Estuary (33° S) in the Eastern Cape, South Africa. This study investigated the influence
of ...
Identification and characterization of a heat-inducible Hsp70 gene from Sorghum bicolor which confers tolerance to thermal stress
(Springer, 2015)
This study describes the first detailed molecular
characterization of the heat shock protein 70 (Hsp70) gene
from Sorghum bicolor, MN1618 designated as SbHsp70-1.
The full-length cDNA of SbHsp70-1 consists of 2524 bp ...
Nonlinear galactic dynamos and the magnetic pitch angle
(American Astronomical Society, 2015)
Pitch angles p of the large-scale magnetic fields B of spiral galaxies have previously been inferred from
observations to be systematically larger in magnitude than predicted by standard mean-field dynamo theory. ...
