ion molecules with general chemical formula as [li(h2o)] (n=1,2,3), have been chosen as model species toinvestigate the chemical properties of hydrated lithium cations. the rhf(scvs)/ugbs level of calculationhas been used for obtaining equilibrium geometries and rho(r) functions (electron density distributions). by theaid of fundamental physical theorems implemented in quantum theory of atoms i...

the aim of this study was to evaluate genotype×environment interaction (gei) of chlorophyll meter readings (spad) of ten durum wheat cultivars, using data obtained from multi-environment trials during two years, at eight locations. stability and genotypic superiority for spad reading was identified using anova and gge biplot analysis. furthermore, the interrelationships among spad reading and o...

we present detailed theoretical studies of the h-bonded complexes formed from interaction between 5-fluorouracil and various six-membered cyclic nitrosamine compounds. in this study, an investigation on intermolecular interactions in x-nu (x = ch2, sih2,bh, alh, nh, ph, o and s) complexes is carried out using density functional theory. the calculations are conducted on b3lyp/6-311++‏‏g** level ...

background: providing holistic nursing care when there is a shortage of personnel and equipment exposes nurses to stress and a higher risk of occupational burnout. humour can promote nurses’ health and influence nursing care. the aim of this study was to describe nurses’ experiences of humour in clinical settings and factors affecting it.   methods : this qualitative study investigated nurses’ ...

the doctor-patient interaction (dpi) plays an important role in the way patients view physicians. thus, response to the question of ''who is a great physician?'' is related to dpi experiences of patients. the aim of this qualitative study was to explore patients' views regarding this subject. based on critical ethnography in one educational hospital in shiraz, iran, the study was performed base...

the binding of drugs by plasma proteins is an important phenomenon, because it influences the size of the free fraction of the drugs in plasma. in this study the influence of dipyridamole (dp) on the protein binding of propranolol (pl) and pl on the protein binding of dp were studied alone and in the presence of nicotine (nc).        the equilibrium dialysis was employed for protein binding stu...

background: prediction of interaction sites within the membrane protein complexes using the sequence data is of a great importance, because it would find applications in modification of molecules transport through membrane, signaling pathways and drug targets of many diseases. nevertheless, it has gained little attention from the protein structural bioinformatics community. methods: in this stu...

objective: parental self-efficacy is associated with increasing mental health in children. there is a paucity of research in iran on the role of parental self-efficacy in increasing mental health status of children. in this preliminary study, we studied the effectiveness of the world health organization international child development program (2002) for children aged 3 years and younger in incr...

the interaction of brilliant green with herring sperm dna was investigated in detail by spectrometric methods in γ-cyclodextrin systems. on the condition of physiological ph, brilliant green prefers to form the 1:1 inclusion complex with γ-cyclodextrin.all the evidences indicated that the binding modes between γ-cyclodextrin-brilliant green and dna were grooving binding and partial non-classica...

introduction: interaction between drugs represents a major clinical concern for health care professionals and their patients. patients affected by both type 2 diabetes and epilepsy may be prescribed pioglitazone and an anti-epileptic drug such as phenytoin  concurrently. the aim of this study was to consider the interaction of pioglitazone with phenytoin in an experimental model. according to t...
