Piper nigrum leaves were collected from five locations from Kerala within a radius of 150 km, altitudinal variance of 1000m and annual rainfall variance of 1400mm. The extracted Piper nigrum leaf oil was profiled using a GC-MS, Beta Caryophyllene was the only constituent that was present in all the five locations, of which the highest concentration was noted in the high altitude region of Idukk...

Human movements have to be very tightly controlled by the neuro-muscular control mechanisms. In free style ski jumps the muscular events were as short as or shorter than 50ms and inter muscular co-contractions started and were synchronized within a time range of less than 5ms [1]. The Piper rhythm shows a neuromuscular control mechanism that can be seen in the EMG during isometric contractions ...

A crystalline compound [{(1,5-(1,3)benzodioxol-5yl)-1-oxo-2,4pentadienyl}-piperidine] and few sesquiterpenes ( Caryophyllene, β–bisabolene, δ –Cadinene, Elemol, (-)Cedreanol, αEudesmol ) were obtained from the toluene extract of dried fruits of Piper nigrum. This is for the first time piperine has been extracted from the cold toluene extract of Piper nigrum along with few other sesquiterpenes. ...

Este artigo trata da trajetória artista americana Adrian Piper no campo performance, a partir retrospectiva organizada pela Universidade de Maryland, Baltimore County. O autor escolheu fazer uma apresentação artista, mais do que descrição exposição, por entender esse é um trabalho ainda pouco conhecido Brasil. A produção dessa vem se desenvolvendo desde os anos 60 e guarda forte aderência princ...

A total of 9 species belonging to 3 genera of keratinophillic fungi were recovered from twelve soil samples collected from different sites in shivamogga using the hair-baiting technique. Most of the fungal species isolated are known to be agents of human and animal infection. The methanolic root extract of Piper longum was evaluated for antifungal activity against the isolated strains to determ...

In vitro activity of the essential oil from Piper diospyrifolium leaves was tested using disk diffusion techniques. The antifungal assay showed significant potencial antifungal activity: the oil was effective against several clinical fungal strains. The majority compounds in the essential oil were identified as sesquiterpenoids by GC-MS and GC-FID techniques.

Communication in ants is based to a great extent on chemical compounds. Recognition of intruders is primarily based on cuticular hydrocarbon (CHC) profile matching but is prone to being cheated. Eucharitid wasps are specific parasitoids of the brood of ants; the immature stages are either well integrated within the colony or are protected within the host cocoons, whereas adult wasps at emergenc...
