The present study was designed to assess the physiological and biochemical changes in roots and shoots of the herb Acalypha indica grown under hydroponic conditions during exposure to lead (Pb) (100-500 mg L(-1)) for 1-12 d. The accumulation of Pb by A. indica plants was found to be 121.6 and 17.5 mg g(-1) dry weight (DW) in roots and shoots, respectively, when exposed to a Pb concentration of 500 mg L(-1). The presence of Pb ions in stem, root and leaf tissues was confirmed by scanning electron microscope (SEM) and Energy-dispersive X-ray spectroscopy (EDX) analyses...

Lead (Pb) contamination has a toxic effect on plant metabolisms, leading to a decrease in biomass production. The free radical nitric oxide (NO) is involved in the mechanism of response to a wide range of abiotic stresses. However, little is known about the interplay between Pb-induced stress and NO metabolism. Peroxisomes are sub-cellular compartments involved in multiple cellular metabolic pathways which are characterized by an active nitro-oxidative metabolism. Thus, Arabidopsis thaliana mutants expressing cyan fluorescent protein (CFP) through the addition of peroxisomal targeting signal 1 (PTS1), which enables peroxisomes to be visualized in vivo by confocal laser scanning microscopy (CLSM) combined with fluorescent probes for nitric oxide (NO), superoxide anion (O2(·-)) and peroxynitrite (ONOO(-)), were used to evaluate the potential involvement of these organelles in the mechanism of response to 150 μM lead-induced stress...

BACKGROUND: The management of uterine-serous-carcinoma (USC) no longer amenable to treatment with surgery, radiation and/or chemotherapy remains dismal. Alternative therapeutic options are desperately needed. CASE: We describe the case of a heavily pretreated 74-year-old patient with a recurrent USC overexpressing HER2/neu at 3 + level by IHC treated with the anti-HER2/neu antibody-drug-conjugate (ADC) trastuzumab-emtansine (TDM-1-Kadcyla-Genentech/Roche). She experienced a remarkable clinical response to TDM-1 with a complete resolution of a large metastatic, radiation/chemotherapy resistant tumor deposit in her abdominal wall muscle confirmed by multiple CAT scans and a prolonged systemic control of her disease...

As components of electronic scrap, rare earth minerals are an interesting but little used source of raw materials that are highly important for the recycling industry. Currently, there exists no cost-efficient technology to separate rare earth minerals from an electronic scrap mixture. In this study, phage surface display has been used as a key method to develop peptides with high specificity for particular inorganic targets in electronic scrap. Lanthanum phosphate doped with cerium and terbium as part of the fluorescent phosphors of spent compact fluorescent lamps (CFL) was used as a target material of economic interest to test the suitability of the phage display method to the separation of rare earth minerals...

BACKGROUND: Thoracic computed tomography (CT) scans are widely performed in clinical practice, often leading to detection of airway or parenchymal abnormalities in asymptomatic or minimally symptomatic individuals. However, clinical relevance of CT abnormalities is uncertain in the general population. METHODS: We evaluated data from 1361 participants aged ≥40 years from a Canadian prospective cohort comprising 408 healthy never-smokers, 502 healthy ever-smokers, and 451 individuals with spirometric evidence of chronic obstructive pulmonary disease (COPD) who had thoracic CT scans...

Fractures of the distal radius are very common. The majority of patients are elderly females. High impact trauma are often responsible for fractures in young men. Clinical and radiological diagnostics, including computer-assisted tomography (CAT) scan, are generally sufficient. The indication for conservative treatment is still recommended for specific fracture patterns. Application of palmar locking plates after open reduction proved to be efficacious for the majority of fracture patterns. Furthermore, precise detection and treatment of concomitant lesions are mandatory in order to prevent complications...

Broad-based species comparisons across mammalian orders suggest a number of factors that might influence the evolution of large brains. However, the relationship between these factors and total and regional brain size remains unclear. This study investigated the relationship between relative brain size and regional brain volumes and sociality in 13 felid species in hopes of revealing relationships that are not detected in more inclusive comparative studies. In addition, a more detailed analysis was conducted of four focal species: lions (Panthera leo), leopards (Panthera pardus), cougars (Puma concolor), and cheetahs (Acinonyx jubatus)...

OBJECTIVE: To review information regarding etiology, pathophysiology, and treatment options for aortic thrombotic disease in dogs. ETIOLOGY: Diseases resulting in hypercoagulable states can cause thrombus formation in the distal aorta, and account for the majority of cases of aortic thrombosis (ATh) in dogs, although a substantial number of cases have no identifiable underlying cause. Aortic thromboembolism (ATE) also occurs but appears to be much less frequently documented...

INTRODUCTION: Stump appendicitis is the remaining appendicular tissue inflammation after a variable length of time. It is a very infrequent pathology with a paucity in pediatric publications, and given the fact that a delay in its diagnosis could lead to an increased morbidity, this is the reason of its clinical relevance. CLINICAL CASE: A 10 years old girl who had laparoscopic excision of a flemonous-gangrenous appendicitis and who 45 days after surgery showed new clinical symptoms compatible with a diagnosis of acute appendicitis...

Peripheral nerve sheath tumors are a heterogeneous group of neoplasms that comprise neurofibromas, schwannomas, neurilemmomas, and perineuromas. In animals, peripheral nerve sheath neoplasms are most commonly diagnosed in dogs and cattle, followed by horses, goats, and cats, but their occurrence is uncommon in birds. An adult, free-living, male toco (common) toucan ( Ramphastos toco ) was admitted to the zoo animal clinic with weight loss, dehydration, and presence of a soft nodule adhered to the medial portion of the left pectoral muscle...

We tested the hypothesis that in atrial myocytes from a rabbit left ventricular heart failure (HF) model, spatial inhomogeneity and temporal dyssynchrony of Ca removal during excitation-contraction coupling together with increased Na/Ca exchange (NCX) activity generate a substrate for proarrhythmic Ca release. Ca removal occurs via Ca reuptake into the sarcoplasmic reticulum and extrusion via NCX exclusively in the cell periphery since rabbit atrial myocytes lack transverse tubules. Ca removal kinetics were assessed by the time constant τ of decay of local peripheral subsarcolemmal (SS) and central (CT) action potential (AP)-induced Ca transients (CaTs) recorded in confocal line scan mode (using Fluo-4)...

The intention of the comparison of both low and high field was to examine which anatomical brain structures of cats were visible on low field images, as in clinical veterinary practice, 3 Tesla (T) magnets were of limited availability. The research was performed on 20 European short-haired male and female cats, aged 1-3 years, with body weight of 2-4 kg. 0.25 T magnetic resonance images of neurocranium were acquired in all using T2-weighted fast spin echo sequences with repetition time (TR) of 4010 ms and echo time (TE) of 90 ms in dorsal and transverse plane, and T2-weighted fast spine echo sequences with TR of 4290 ms and TE of 120 ms in sagittal plane...

Our objective was to assess the accuracy of virtual and printed 3-dimensional models derived from cone-beam computed tomographic (CT) scans to measure the volume of alveolar clefts before bone grafting. Fifteen subjects with unilateral cleft lip and palate had i-CAT cone-beam CT scans recorded at 0.2mm voxel and sectioned transversely into slices 0.2mm thick using i-CAT Vision. Volumes of alveolar clefts were calculated using first a validated algorithm; secondly, commercially-available virtual 3-dimensional model software; and finally 3-dimensional printed models, which were scanned with microCT and analysed using 3-dimensional software...

BACKGROUND: Immunomodulatory interventions play a key role in the treatment of infections and cancer as well as allergic diseases. Adjuvants such as micro- and nanoparticles are often added to immunomodulatory therapies to enhance the triggered immune response. Here, we report the immunological assessment of novel and economically manufactured microparticle adjuvants, namely strontium-doped hydroxyapatite porous spheres (SHAS), which we suggest for the use as adjuvant and carrier in allergen-specific immunotherapy (ASIT)...

The physicochemical and biological properties of metals change as the particles are reduced to nanoscale. This ability increases the application of nanoparticles in commercial and medical industry. Keeping in view this importance, Silver nanoparticles (Ag-NPs) were synthesized by reduction methods using formaldehyde as reducing agent in the chemical route and lemon extracts in the biological route. The scanning electron microscope (SEM) images of nanoparticles suggested that the particles were either agglomerated or spherical in shape with mean diameter of 16...
