These studies were undertaken to characterise resorcinolic lipids (5-n-alk(en)ylresorcinols) composition and to determine their seasonal fluctuations in fruit pulp and leaves of Ginkgo biloba L. Resorcinolic lipid concentrations were consistently higher in fruit pulp than in leaves. In pulp, several mono- and di-unsaturated homologs of alkylresorcinols were the predominant group of analysed lip...

Two trials were conducted to evaluate the effects of corn or dried beet pulp on intake and digestibility of forage by lambs and on IVDMD. In Trial 1, 16 lambs (average BW = 41 +/- .9 kg) were used in a randomized complete block design with eight lambs per block. Lambs were fed a crested wheatgrass hay (7.5% CP) and received either no supplement (NS), a protein supplement (PS), or protein supple...

BACKGROUND Pulp stones are discrete calcified bodies found in the dental pulp. The aims of this study were to calculate the prevalence of pulp stones in young Australian adults using radiographs, and to report any associations between occurrence of pulp stones and sex, tooth type, dental arch, side and dental status. METHODS From 217 undergraduate dental students, comprising 123 males and 94 ...

A root canal treatment generally involves the removal and replacement of a tooth’s pulp. The pulp is soft tissue containing blood vessels, nerves and connective tissue. dThe pulp is found in a canal that runs through the center of the hard tissue on the inside of the tooth (the dentin). dThe pulp extends from the pulp chamber in the crown down through the root canal to the tip of the root in th...

OBJECTIVE This study evaluated the presence of microorganisms and analyzed microscopically the pulp of 20 traumatized human teeth with intact crowns and clinical diagnosis of pulp necrosis, based on the association of at least three of the clinical criteria: crown discoloration, negative response to thermal and electric pulp vitality tests, positive response to vertical and horizontal percussio...

BACKGROUND In equine practice, teeth corrections by means of motorized grinding systems are standard procedure. The heat resulting from that treatment may cause irreparable damage to the dental pulp. It has been shown that a 5.5°C temperature rise may cause severe destruction in pulp cells. Hence, the capability to continuously form secondary dentine is lost, and may lead, due to equine-typical...

INTRODUCTION The purpose of this study was to assess the accuracy of sensibility tests by correlating it with histologic pulp condition. METHODS AND MATERIALS Assessment of clinical signs and symptoms were performed on 65 permanent teeth that were scheduled to be extracted for periodontal, prosthodontic or orthodontic reasons. The normal pulp and reversible pulpitis were considered as treatab...

Studies on strength delivery and related fields have so far concentrated on finding the locations in the mill where fibres are damaged and what the damages consist of. However, fibres will invariably encounter mechanical stresses along the fibreline and in this thesis a new concept is introduced; the vulnerability of fibres to mechanical treatment. It is hypothesised that fibres with different ...

A thermoalkalophilic and cellulase-free xylanase produced from Arthrobacter sp. MTCC 5214 by solid-state fermentation using wheat bran as a carbon source was evaluated for prebleaching of kraft pulp. The UV absorption spectrum of the compounds released by enzyme treatment showed a characteristic peak at 280 nm, indicating the presence of lignin in the released colouring matter. Enzymatic preble...
