In this study, a novel adsorbent, dioctylphetalate triethylenetetraamine magnetic nanoparticles (DOP-TETA-MNP) via a solvent-free procedure were synthesized for the removal of Zn (II) ions from aqueous solution. The morphological and anatomical characterization was investigated by various analytical techniques such as FTIR and SEM. Experimental data from evaluation of various influential parameters such as initial pH (2–7), initial ion concentration (5–20 mg/L), adsorbent dose (0.005–0.040 g), contact time (5–120 min) and temperature (308–333 K) of the solution were carried out using a batch adsorption method. DOP-TETA-MNP can be simply separated from aqueous solution with magnetic separations at low magnetic field. The kinetic data of Zn (II) ions were found to follow the pseudo-second-order kinetic model and the equilibrium data of ions sorption were well described by Langmuir isotherm model. The maximum monolayer sorption capacity of Zn (II) was estimated to be 24.21 mg/g at temperature of 333 K. Thermodynamic analyses show that the adsorption process is exothermic and spontaneous.

Anesthesia and analgesia are major components of many interventional studies on laboratory animals. However, various studies have shown improper reporting or use of anesthetics/analgesics in research proposals and published articles. In many cases, it seems “anesthesia” and “analgesia” are used interchangeably, while they are referring to two different concepts. Not only this is an unethical practice, but also it may be one of the reasons for the proven suboptimal quality of many animal researches. This is a widespread problem among investigations on various species of animals. However, it could be imagined that it may be more prevalent for the most common species of laboratory animals, such as the laboratory mice. In this review, proper anesthetic/analgesic methods for routine procedures on laboratory mice are discussed. We considered the available literature and critically reviewed their anesthetic/analgesic methods. Detailed dosing and pharmacological information for the relevant drugs are provided and some of the drugs’ side effects are discussed. This paper provides the necessary data for an informed choice of anesthetic/analgesic methods in some routine procedures on laboratory mice.

Background: Cancer is one of the common causes of disability and mortality in the world. The present study aimed to define the spatiotemporal distribution of gastrointestinal tract cancers using a geographic information system (GIS) over the time period of 2007-2012 in Kermanshah-Iran. Materials and Methods: The method of studying was descriptive-analytical as well as comparative with gastrointestinal tract cancer patients based in the City of Kermanshah over the time period covered. For data analysis, the GIS and SPSS 16.0 were applied. Results: According to the pathological reports within the space of 5 years, 283 cases of gastrointestinal tract cancer (157 in males, 156 in females) were reported. The performed tests in terms of spatial distribution in the environment of GIS indicated that the disease demonstrated a clustered pattern in the City of Kermanshah. More to the point, some loci of this disease have emerged in the City of Kermanshah that in the first level, 6 neighborhoods with 29-59 cases of this disease per square kilometer and in the second level, 15-29 cases. Conclusions: Gastrointestinal tract cancer demonstrated an ascending trend within the space of 5 years of research and the spatiotemporal distribution of cancer featured a concentrated and clustered pattern in the City of Kermanshah.
