Single-step fusion-based affinity purification of proteins with pH-controllable linkers was carried out in a fluidic device. The linkers were previously derived from self-splicing protein elements called inteins. Two different linkers were generated to solve two distinct separation problems: one for rapid single-step affinity purification of a wide range of proteins, and the other specifically ...
Peptides and proteins can convert from their soluble forms into highly ordered fibrillar aggregates, giving rise to pathological conditions ranging from neurodegenerative disorders to systemic amyloidoses. It is increasingly recognized that protein oligomers forming early in the process of fibril aggregation represent the pathogenic species in protein deposition diseases. The N-terminal domain ...
Migratory grazing of zooplankton between non-toxic phytoplankton (NTP) and toxic phytoplankton (TPP) is a realistic phenomena unexplored so far. The present article is a first step in this direction. A mathematical model of NTP–TPPzooplankton with constant and variable zooplankton migration is proposed and analyzed. The asymptotic dynamics of the model system around the biologically feasible eq...
Background and Aims: Medicinal plants possess a variety of beneficial characteristics without causing substantial adverse effects. Antimicrobial activity is one of the qualities, among many others, that have been identified. Althaea officinalis is an annual plant belonging to the Malvaceae family with therapeutic qualities in both the leaves and the roots. Specifically, the effects of Althaea o...
OBJECTIVES To evaluate procalcitonin (PCT) utility as a marker of medullary thyroid cancer (MTC). MATERIAL AND METHODS Calcitonin (CT) and PCT levels were measured in MTC patients and patients with serious bacterial infections. 70 patients were enrolled in the study: 6 MTC active patients: 4 with disseminated, unreoperable disease and 2 re-operated patients, in whom markers were checked befor...
Serum anti-thyroglobulin antibody (TgAb) and anti-thyroid microsomal antibody (McAb) in 213 cases of thyroid disorders and 32 cases of non-thyroid disorders were studied. The antibodies were checked by commercial tanned red cell hemagglutination kits (Thymune-T and Thymune-M) purchased from Wellcome Reagents, Limited, England. The positive rates of TgAb and McAb in patients with untreated toxic...
The aim of this study was to assess the prevalence of non toxic goiter, difuse or nodular, in all Genoa's Country thyroid diseases. The authors have studied one non-random casuistry of 1980 Patients observed from time to time in the last decade in Ambulatory of Nuclear Medicine (Department of Internal Medicine of University of Genoa) working with Section of Hygiene of ASL of Genoa. Of 1980 pati...
abstract: peganum harmala l. (zygophylaceae) has been used in a variety of practical applications in medical science. our objective in the current study was to determine the effects of the seed extract on herpes simplex virus type 1 (hsv-1) replication in vero cells. different concentrations (100, 500, 571, 667, 800 and 1000 µg/ml) of the extract were examined. experiments were carried out usin...
