Antibiotic resistance is an important problem in antibiotic treatment of infections, particularly in hospitals. Tomatidine is a plant secondary metabolite with antimicrobial and antifungal effects. This study examined the possible synergistic effect tomatidine with several antibiotics against standard and clinical strains of Staphylococcus aureus, Enterococcus faecalis, Pseudomonas aeruginosa a...

The purpose of this paper is to find the optimal geometry of Venturi for the production of biodiesel by hydrodynamic cavitation. Intensive methods such as hydrodynamic cavitation eliminate the limitation of mass transfer in the transesterification reaction. In this paper, a venturi design was developed to create cavitation in biodiesel production. The most important property of ven...

avian reoviruses (arvs) are considered as an important cause of several diseases in poultry, particularlyarthritis and tenosynovitis. tenosynovitis and arthritis, which are among the causes of chronic lameness inbreeder flocks, can result in reduced egg production and culling of breeder hens. in this study, the molecularcharacteristics of arvs in some broiler breeder flocks were investigated in...

Phenolic and flavonoid compounds are secondary metabolites of plants which possess various activities such as anti-inflammatory, analgesic, anti-diabetes and anticancer effects. It has been established that these compounds can scavenge free radicals produced in the body. Because of this ability, not only the plants containing phenolic and flavonoid compounds but also, the pure compounds are use...

Despite recent advances, we still do not understand how chronic nutrient enrichment impacts coastal plant community structure and function. We aimed to clarify such by testing for differences in ecosystem productivity multiple metrics response fertilization. established plots 2015 consisting of control (C), nitrogen (N), phosphorus (P), + (NP) treatments a mid-Atlantic grassland. In 2017 collec...

Key to understanding forest water balances is the role of tree species regulating evapotranspiration (ET), but synergistic impact composition, topography, and availability on ET how this shapes drought sensitivity across landscape remains unclear. Our aims were quantify (1) effect composition topography including elevation hillslope gradients relationship between availability, (2) whether has c...

‎In this paper‎, ‎we study the Neumann boundary value problem of a class of nonlinear divergence type diffusion equations‎. ‎By a priori estimates‎, ‎difference and variation techniques‎, ‎we establish the existence and uniqueness of weak solutions of this problem.

Fungal infection has become one of the leading causes of hospital-acquired infections with high mortality rates. Furthermore, drug resistance is common for fungus-causing diseases. Synergistic drug combinations could provide an effective strategy to overcome drug resistance. Meanwhile, synergistic drug combinations can increase treatment efficacy and decrease drug dosage to avoid toxicity. Ther...
