Size structure and spatial arrangement of 13 abundant tree species were determined in a riparian forest fragment in Paraná State, South Brazil (23°16'S and 51°01'W). The studied species were Aspidosperma polyneuron Müll. Arg., Astronium graveolens Jacq. and Gallesia integrifolia (Spreng) Harms (emergent species); Alseis floribunda Schott, Ruprechtia laxiflora Meisn. and Bougainvillea spectabili...

Remembering events from the personal past (autobiographical memory) and inferring the thoughts and feelings of other people (mentalizing) share a neural substrate. The shared functional neuroanatomy of these processes has been demonstrated in a meta-analysis of independent task domains (Spreng, Mar & Kim, 2009) and within subjects performing both tasks (Rabin, Gilboa, Stuss, Mar, & Rosenbaum, 2...

Evolutionary relationships among 48 genera of Apiaceae (Umbelliferae) were inferred using maximum parsimony, maximum-likelihood, and neighbor-joining analyses of chloroplast DNA rps16 intron and adjacent rps16 3′ exon sequences. Emphasis was placed on woody members of Apiaceae subfamily Apioideae endemic to southern Africa, a region hypothesized to be the place of origin of this largely herbace...

The chemical composition of the essential oils obtained from the aerial parts of Helichrysum cymosum and H. fulgidum, from Tanzania, were analyzed by GC and GC/MS. A total of sixty-five compounds, representing 92.4% and 88.2% of the two oils, respectively, were identified. trans-Caryophyllene, caryophyllene oxide, beta-pinene, p-cymene, spathulenol and beta-bourbonene were found to be the main ...

An experiment was conducted to evaluate the effects of methanolic extracts of Murraya koenigii Spreng. (Curry leaf) and Morus alba Linn. (Mulberry leaf) on the age of attainment of puberty, relative ovary and uterus weight and the number of ovarian surface follicles in female Wistar albino rats. The rats were reared from 20 to 70 days of age in six groups consisting of eight rats in each group....

Poison hemlock (Conium maculatum) is one of the most poisonous plants in the world. Accidental ingestion of the plant could result in central nervous system depression, respiratory failure and even death. Airway and breathing management followed by fluid resuscitation is the mainstay of treatment. Poison hemlock poisoning is an important differential diagnosis for patients with impaired conscio...
