Abstract Elaeodendron transvaalense Jacq. is one of the medicinal plant species commonly used by people in the Venda region. The species is known to treat a variety of diseases. It is widely used and important to traditional healers. Because of this, it found its way into the muthi markets, and it is among the seven most commonly traded plant species in the Venda region. This study investigated the impact of bark harvesting on the population structure of this species. The study revealed that although the level of bark harvesting is high, the species is able to resist More >

Abstract Chromium (Cr) is a highly toxic non-essential metal for microorganisms and plants; due to its frequent industrial use, it has become a pollutant for different agroecosystems. Arbuscular mycorrhizal fungi (AMF) are associated with most angiosperms and provide them with beneficial effects on the absorption of some nutrients. Moreover, it has been reported that in some cases the AMF can confer greater tolerance to plants in the presence of heavy metals. The tomato (Solanum lycorpersicum) is an important crop in Mexico. In most cases, it grows under applied irrigation water from reservoirs which include domestic and industrial… More >

Abstract The data collection approach called Participatory Rural Appraisal (PRA) was used in five villages: Killi Tor Shore; Medadzai; Ghunda; Kala Ragha, and Killi Shaban. Up to five groups were sampled in each village, comprising a total of 17 villages within the Zarghoon Juniper ecosystem. This area is rich both historically and culturally for using medicinal plants, mostly by women (60%). In this study, 26 species of medicinal plants fit in 20 genera and 13 families. They are used by aboriginal people via the indigenous knowledge they have for the treatment of many diseases. About 60,… More >

Abstract Bee pollen has gained increased interest in recent decades due to its therapeutic, antioxidant, antifungal and anticariogenic properties, as well as its potential use as a functional food product in the food industry because of its nutritional properties. Therefore, it is necessary to identify the chemical components of pollen extracts with different botanical origin, supporting the hypothesis that bee products inherit the characteristics and bioactive properties from the plants they come from. The purpose of this study was to conduct a chemical characterization of samples of pollen collected by Apis mellifera L. from plants native to… More >

Abstract Species of the genus Psychotria are used for multiple purposes in Brazilian folk medicine, either as water infusions, baths or poultices. This study was aimed to evaluate the genotoxic and antiproliferative effects of infusions of Psychotria brachypoda and P. birotula on the Allium cepa test. Exposure to distilled water was used as a negative control, while exposure to glyphosate was used as a positive control. The interaction of extracts (as a post-treatment) with the effects of glyphosate was also studied. Results showed that glyphosate and the extracts of both P. brachypoda and P. birotula reduced the mitotic index as compared… More >

Abstract The success of sexual plant reproduction is directly influenced by specific interactions between the pollen and pistil. Light, fluorescence and scanning electron microscopy techniques were used to evaluate the steps of pollination in sour passion fruit plants (Passiflora edulis Sims). In the compatible interaction, pollen tubes grow through stigma projections towards the ovary. The pollen grain surface was found to be spheroidal and to consist of heteroreticulate exine with six colpi. Furthermore, analysis in vivo of pollenpistil interactions indicated that stigmas of flowers 24 hours before anthesis are unable to discriminate compatible (genetically unrelated) and More >

Abstract The goals of this study were (1) to make a careful study of the foliar epidermis of Grindelia cabrerae var. cabrerae, Solidago chilensis y Wedelia buphthalmiflora, native Asteraceae from Argentina which have ornamental potential, and (2) to determine variables that indicate adaptation to xeromorphic environments. Five adult leaves from five plants were selected from each population. All the material was fixed in FAA. The epidermis of both foliar sides were macerated in hypochlorite of sodium, and obtained by scraping. They were stained with safranine and mounted in water-glycerine (1:1). From each slide, five fields were chosen and… More >

Abstract Rhizospheric soil is one the largest reservoirs of microbial genetic diversity. Before conducting a large-scale metagenomic analysis of an environment, such as a rhizospheric soil, it is necessary to perform a pre-screening of the resident genetic diversity. In this study, we analyzed the bacterial diversity associated with the rhizosphere of wheat plants by PCR amplification, construction of a library and sequencing of 16S rDNA genes. Thirty OTUs were detected, including the Classes Alfaproteobacteria, Betaproteobacteria, Deltaproteobacteria, Gammaproteobateria, Actinobacteria, Bacilli, Clostridia and Uncultivable bacteria. Within the Gammaproteobacteria class, the genera Pseudomonas, Stenotrophomonas and Bacillus were the most abundant, since More >

Abstract Chronic monitoring of bladder volume can improve the clinical diagnosis and the choice of therapeutic approach for patients suffering from urinary dysfunction. It can also be employed to notify patients or healthcare personnel when the bladder should be emptied. An early warning can be triggered either when functional bladder capacity is reached or when an abnormally high postvoiding residual volume remains in the bladder after an unfinished voiding. Currently, neuroprosthetic implants are used in the treatment of refractory patients with overactive bladder, with urgency-frequency or with voiding complications. These implants can further enhance their performance, More >
