In biotransformations carried out under similar conditions enzymatic systems from carrot (Daucus carota L.), celeriac (Apium graveolens L. var. rapaceum) and horse-radish (Armoracia lapathifolia Gilib.) hydrolyzed the ester bonds of acetates of phenols or alicyclic alcohols. Nevertheless, methyl esters of aromatic acids did not undergo hydrolysis. Alcohols were oxidized to ketones in a reversib...

Visuo-spatial integration is indeed one of the cognitive domains in which humans have clearly undergone evolutionary development (Wynn, 1989, 2010). Our ability to conceive of and organize our actions in space is arguably unmatched among primates. And as Bruner & Lozano explicate, this spatial cognition relies on our ability to generate an " inner virtual space " using neural resources of the I...

This article analyzes the materials of “Set additions and changes to check-list flora Republic Buryatia from 2001 2020”. Corrections comments are given on 50 species higher vascular plants, both erroneously cited as novelties, and, contrary, absent original publication, regarding territory Baikalsky State Nature Reserve its buffer zone. Two taxa amongst omitted in source material included Red D...

Species differences in patterns of phenotypic plasticity may be an important aspect of adaptive diversity. Plasticity for functionally important root traits was studied in inbred field lineages of Polygonum persicaria and P. cespitosum (Polygonaceae). Replicate seedlings were grown in plexiglass rhizotrons under a range of constant and temporally variable moisture treatments. Plasticity was det...

Adaptive differences among species are often thought to result from developmentally constant trait differences that enhance fitness in alternative environments. Species differences in patterns of individual phenotypic plasticity can also have ecological consequences. Indeed, functionally related constant and plastic traits may interact to determine the phenotype’s adaptive value in particular c...

Here we examined species differences in perception and response to two distinct types of shade cue, reduced photosynthetically active radiation (PAR) with and without reduced red : far red ratio (R : FR), in Polygonum persicaria and Polygonum hydropiper, two closely related annuals of contrasting ecological breadth. We compared plasticity data for light-gathering traits from glasshouse experime...

OBJECTIVE To evaluate whether occlusive salpingitis isthmica nodosa associated with endometriosis can be diagnosed by microlaparoscopy and managed with medical therapy using leuprolide acetate. METHODS This was a prospective, nonrandomized study conducted at a university hospital and a private community hospital. It included women with occlusive salpingitis isthmica nodosa associated with end...

Polyarteritis nodosa is a necrotizing vasculitis of medium-sized arteries of unknown origin. Hypertension is present in 30% of patients with polyarteritis nodosa. In those cases, high renin levels are thought to be secondary to renal involvement. The present study was performed to identify causal factors of polyarteritis nodosa. In cyp1a1ren-2 transgenic rats, vasculitis of medium-sized arterie...

The nuclear ribosomal DNA internal transcribed spacer (ITS) sequences from 44 Indian Polygonum taxa were examined to investigate relationships among various sections proposed by earlier researchers. The maximum parsimony trees obtained from analysis of the ITS sequences suggested eight major groups of the Indian Polygonum spp. The relationships among different sections were largely congrue...
