This investigation was aimed to provide a pharmacologic basis to the medicinal use of Acorus calamus in cardiovascular disorders. In normotensive anesthetized rats, crude extract of Acorus calamus and its ethylacetate and nHexane fractions caused a fall in mean arterial pressure. In rabbit aorta rings, crude extract was more potent against high K (80 mM), ethylacetate against phenylephrine (1 m...

AIM: Prolonged exposure to stress mainly affects the cognitive functions of the brain by inducing neuronal damage mediated through oxidative stress. Acorus calamus (AC) has long been used in Indian folk medicine for various central nervous system (CNS) abnormalities.

In a feather, there are distinct morphologies along the proximal-distal axis. The proximal part is a cylindrical stalk (calamus), whereas the distal part has barb and barbule branches. Here we focus on what molecular signaling activity can modulate feather stem cells to generate these distinct morphologies. We demonstrate the drastic tissue remodeling during feather cycling which includes initi...

Calamus erectus Roxb. (CE) fruit under the family Arecaceae is traditionally used by the local people of Darjeeling Himalaya as an antidiabetic agent but no scientific reports are available yet. Hence this study was designed to determine the in vitro antioxidant and antidiabetic activities of two different parts viz. mesocarp and endocarp of Calamus erectus fruit. The extracts were screened for...

A. calamus that grows in province of Baluchistan and Kerman in Iran plays a major role in the revival of traditional medicine. Despite the useful role of this plant in many ailments, its anti-bacterial properties are not well understood. In this study, we investigated anti-bacterial activities of rhizomes ware of A. calamus against various strains of bacteria such as Staphylococcus aureus and E...

The article addresses the role played within the social imaginary of Brazil by the scientific voyages of physicians in the first half of the twentieth century. Two texts are analyzed: a report by Arthur Neiva and Belisário Penna published in Memórias do Instituto Oswaldo Cruz and another by Julio Paternostro, released in 1945 in Viagem ao Tocantins. The former contributed to singling out pathol...

Eremospatha dransfieldii is a robust rattan palm, climbing up to 40 m in length. It is only known to occur in the south-western region of Ghana, south-eastern part of Côte d'Ivoire and in Sierra Leone. The species' Area of Occupancy (AOO) is restricted to just 40 km2. This species is confined to moist-evergreen forests with high rainfall. It is known to be facing habitat loss and over-harvestin...
