Background: During the last two decades, significant advances have been made in the fields of lactococcal genetics and protein expression. Lactococcus lactis (L. lactis) is an effective vector for protein expression and can be used as an antigen delivery system. Hence, L. lactis is an ideal candidate for mucosal immunotherapy. Profilin (Che a 2), the major allergen in Chenopodium album, is one ...

In B. subtilis swarming and robust swimming motility require the positive trigger of SwrA on fla/che operon expression. Despite having an essential and specific activity, how SwrA executes this task has remained elusive thus far. We demonstrate here that SwrA acts at the main σ(A)-dependent fla/che promoter PA(fla/che) through DegU. Electrophoretic mobility shift assays (EMSA) reveal that SwrA ...

In questo lavoro viene proposta una estensione del linguaggio datalog [CP97]. datalog è un linguaggio logico basato su datalog, la cui innovazione sostanziale consiste nell’aumento della potenza espressiva, tramite l’introduzione di una semantica basata sulla circoscrizione, un meccanismo deduttivo non monotòno che generalizza l’ipotesi di mondo chiuso. Questo tipo di semantica fornisce interes...

Peach harvest workers were evaluated for exposure to azinphosmethyl residues by measuring foliar residues, urinary alkyl phosphate metabolites, plasma and erythrocyte (RBC) cholinesterase (ChE), and dermal residues using clothing and skin washes. Workers entered orchards 51 days after application and worked in treated fields for ten of the next 17 days. Dislodgeable foliar residues ranged from ...

Sommario Nei sistemi P2P un serio problema che ne limita la scalabilità è l’esplosione di traffico dovuto al fatto che ogni peer propaga le query a tutto l’insieme dei peer ad esso noti. In questo lavoro affrontiamo tale problema proponendo una strategia per ridurre il numero di peer a cui propagare le query selezionando quei peer verso i quali l’aspettativa è alta. L’innovatività della propost...

Diblock copolymer nanoparticles encapsulating a paclitaxel prodrug, Propac 7, have been used to demonstrate the usefulness of a nonmetabolizable radioactive marker, cholesteryl hexadecyl ether (CHE), to evaluate nanoparticle formulation variables. Since CHE did not exchange out of the nanoparticles, the rate of clearance of the CHE could be used as an indicator of nanoparticle stability in vivo...

BACKGROUND The major objective of the National Health Insurance Scheme (NHIS) in Nigeria is to protect families from the financial hardship of large medical bills. Catastrophic Health Expenditure (CHE) is rampart in Nigeria despite the take-off of the NHIS. This study aimed to determine if households enrolled in the NHIS were protected from having CHE. METHODS The study took place among 714 h...

Siamo interessati a risolvere i seguenti problemi: Problema 1 (Covering Problem,CP) Trovare la copertura di costo totale minimo, cioè il sottoinsieme J ′ di J tale che: 1. Ognuna delle caselle è ricoperta da almeno un pezzo contenuto in J ; 2. La somma dei “costi” dei pezzi di J ′ è minima tra tutti i sottoinsiemi che soddisfano (1). Problema 2 (Partitioning Problem,PP) Trovare la partizione di...
