• Characterization of turnover times of fine roots is essential to understanding patterns of carbon allocation in plants and describing forest C cycling. We used the rate of decline in the ratio of 14 C to 12 C in a mature hardwood forest, enriched by an inadvertent 14 C pulse, to investigate fine-root turnover and its relationship with fine-root diameter and soil depth. • Biomass and ∆ 14 C va...

BACKGROUND The roots of primary molars were found in the permanent dentition without symptoms on the clinical or radiographic examination. However, their incidence could not be achieved on the current literature. OBJECTIVE The aim of this study is to evaluate the radiographic features of the embedded primary molar roots in adult dentulous patients in Turkey. MATERIALS AND METHODS The data, ...

Salinity negatively affects plant growth and causes significant crop yield losses world-wide. Maize is an economically important cereal crop affected by high salinity. In this study, maize seedlings were subjected to 75 mM and 150 mM NaCl, to emulate high soil salinity. Roots, mature leaves (basal leaf-pair 1,2) and young leaves (distal leaf-pair 3,4) were harvested after 3 weeks of sowing. Roo...

Using a Non-invasive Micro-test Technique, flux profiles of Cd2+, Ca2+, and H+ were investigated in axenically grown cultures of two strains of Paxillus involutus (MAJ and NAU), ectomycorrhizae formed by these fungi with the woody Cd2+-hyperaccumulator, Populus × canescens, and non-mycorrhizal (NM) roots. The influx of Cd2+ increased in fungal mycelia, NM and ectomycorrhizal (EM) roots upon a 4...

PURPOSE The purpose of this animal study was to perform a histological and histomorphometric analysis in order to elucidate the effect of fibroblast growth factor-2 (FGF-2) on injured periodontal ligament (PDL) and cementum after tooth replantation in dogs. METHODS The roots of 36 mandibular premolars from six mongrel dogs were used in this study. The roots were randomly divided into three gr...

Coal mining and related industry can increase heavy metals (HMs) concentrations in soil, atmosphere and wheat, thereby posing metal-associated human health risk via food ingestion.  In this study, 58 samples of soil, wheat, and dust were collected from Xuzhou coal mine eastern China, six kinds of HMs Pb, Cd, Cu, Zn, As and Cr were studied for their spatial distribution in wheat, enrichment in d...

Laminitis (also known as Founder) is one of the most devastating and feared diseases from which horses can suffer . It is caused by extremely painful inflammation in the sensitive laminae in the hoof, and can result in death or permanent lameness . Recent research has shed new light on the causes of laminitis . Most importantly, we now know what owners can do to minimize their own horse’s risk ...
