Soft rot caused by pectolytic bacteria makes annual production and storage losses throughout the world. This study aimed to detect and identify pathogenic Pseudomonas causing soft rot in some of the vegetables and ornamentals.

During the growing seasons of 2015–17, plant samples of eggplant, maize, radiator plant, sweet pepper and tomato with water soak and soft rot symptoms were collected. Biochemical and morphological features were characterized according to the standard bacteriological criteria. The tuf encoding gene from these representatives was amplified using Bac-tuf-F and Bac-tuf-R primers, subjected to sequencing and aligned in the NCBI.

Total of 120 isolates were recovered from the samples. Based on synthesizing pectic enzymes, five putative Pseudomonas strains were selected. Based on the DNA sequence-based phylogeny, in combination with biochemical and morphological characteristics, these soft rot Pseudomonas were identified as Pseudomonas aeruginosa, P. entomophila, P. mosselii and P. putida. Koch's postulates were verified by re-isolating the strains from inoculated plant segments. Discussion and

To the best of our knowledge, this is the first evidence of the pathogenicity of P. aeruginosa on tomato, P. entomophila on sweet pepper and P. putida on eggplant. Furthermore, this study firstly reports the association of P. aeruginosa and P. mosselii with soft rot in maize and radiator plant, respectively.

The aim of this study was to investigate the effect of adding risperidone to the general behavioral treatment of masturbation in children 3‑7 years old.

A 4 week randomized clinical controlled trial was designed in year 2009. Samples have been chosen from children who have been referred to the Child and Adolescence Psychiatric Clinic of Isfahan University of Medical Sciences. Ninety children were recruited at the study and randomly allocated into the risperidone and control groups (44 and 46 respectively). The risperidone group was medicated simultaneously by behavioral treatments and 0.25‑1 mg of risperidone daily while the controls only received the behavioral treatments.

The mean ± SD age of the risperidone and control groups was 5.3 ± 1.1 and 4.9 ± 1.1 years, respectively. The mean ± SD of the period of suffering from masturbation was 3.4 ± 1.2 and 3.8 ± 1.7 months in the risperidone and the control groups, respectively. At the beginning of the study, the mean frequency of masturbation in control and the risperidone groups was 2.6 ± 0.9 and 2.7 ± 0.9 times/day, whereas after the 4th week, it decreased to 1.4 ± 0.6 and 1.1 ± 0.5 times/day, respectively. The results showed a more reduction in the mean frequency of masturbation in the risperidone group significantly.

In comparison to the general behavioral treatment, risperidone in addition to the behavioral treatment will probably reduce the frequency of masturbation in children more effectively.

Multiple Sclerosis (MS) is a neurological disease in which demyelination and axonal loss leads to progressive disability. Cognition impairment is among the most common complication. Studying axonal loss in the retina is a new marker for MS. The main goal of our study is to search for correlations between magnetic resonance imaging (MRI) findings and the retinal nerve fiber layer (RNFL) thickness at the macula and head of the optic nerve and Wechsler Adult Intelligence Scale-Revised (WAIS-R) Scores that assess multiple domains of intelligence, and to explore the relationship between changes in the RNFL thickness with intellectual and cognitive dysfunction.

A prospective cross-sectional study was conducted at the University Hospital of Kashani, Isfahan, Iran, from September to December 2013. All patients were assessed with a full-scale intelligence quotient (IQ) on the WAIS-R. An optical coherence tomography study and brain MRI were performed in the same week for all the patients. Statistical analysis was conducted by using a bivariate correlation, by utilizing SPSS 20.0. A P value ≤ 0.05 was the threshold of statistical significance.

Examination of a 100 patients showed a significant correlation between the average RNFL thickness of the macula and the verbal IQ (P value = 0.01) and full IQ (P value = 0.01). There was a significant correlation between brain atrophy and verbal IQ.

The RNFL loss was correlated with verbal IQ and full IQ.

Radiation therapies are commonly used for malignant or metastatic brain tumors for curative and palliative use. The radiation-induced neurotoxicity includes both parenchymal and vascular damage. Here we report the case of a 43-year-old woman who developed Multiple sclerosis (MS) 9 months after she underwent the last session of radiotherapy for the diagnosed meningioma. Conventional doses of radiation might trigger MS.
