We tested the generalist annual plant Polygonum persicaria (Polygonaceae) for adaptive differentiation in drought responses. Populations from one consistently moist and two variably dry sites were grown in moist and drought conditions in a greenhouse. Physiological, morphological, and reproductive data were collected. All three populations maintained similar levels of fitness in both drought an...

Research into the evasion of drug resistance and adverse effects is highly significant and urgent in the clinic. Therefore, accumulating studies have focused on the development of novel target-specific molecules related to drug resistance, and the establishment of rational therapeutic approaches. Currently, studies have shown that NF-κB activation may play an essential role in the development o...

Tlie current issue of Pain Research & Management contains an authoritative review of the efficacy of specific nonpharmacological interventions for acute procedural pain in children up to three years of age (1) (pages 321 -330), which is an abridged version of a more exhaustive review (2). These publications provide strong justification for health care professionals and parents, as well as other...

BACKGROUND Socioeconomic mortality differentials are known to exist almost universally. Many studies show a trend towards convergence with increasing age. Information about the highest ages is very rare, though. OBJECTIVE We want to find out whether socioeconomic factors determine the chance of death in the United States among the oldest people. METHODS Based on official death count records, we...

BACKGROUND Persicaria hydropiper (Linn.) Delarbre is a common plant of Polygonaceae family commonly called Bishkatali in Bangladesh. Leaves of the plant are traditionally used in the treatment of rheumatic pain, gout, and skin diseases such as ringworms, scabies, boils, abscesses, carbuncles, bites of snakes, dogs or insects. This study evaluated the antinociceptive effect of the methanol extra...

BACKGROUND Sesquiterpenes are 15-carbon terpenes synthesized by sesquiterpene synthases using farnesyl diphosphate (FPP) as a substrate. Recently, a sesquiterpene synthase gene that encodes a 65 kDa protein was isolated from the aromatic plant Persicaria minor. Here, we report the expression, purification and characterization of recombinant P. minor sesquiterpene synthase protein (PmSTS). Insig...
