Sleep Quality and Self-compassion as Predictors of Aggression in High School Students
In the current study, the relationships between Aggression, Self-compassion and Sleep Quality of high school students have been examined. 529 high school students (66% females and 34% males) participated in the study. Data were collected from participants through using a Pittsburgh Sleep Quality Index (PSQI), Aggression Questionnaire (AQ), Self-Compassion Scale (SCS), and Descriptive Questionnaire. The predictors of aggressiveness of the variables determined by simple correlation were investigated by multiple linear regression. According to the results, there was a positive and significant relationship between aggression levels and all sub-dimensions of self-compassion and sleep quality. In addition, it was observed that the levels of aggressiveness were significantly predicted by the sub-dimensions of self-compassion and sleep quality, and that the first three most effective predictive variables were over-identification, self-judgment and sleep quality
Renal Medullary Carcinoma; A Rare Entity
Renal medullary carcinoma (RMC) is an uncommon aggressive neoplasm of the kidney. RMC is biologically aggressive with a very poor prognosis, and metastasis is seen in up to 95% of the patients at diagnosis or shortly thereafter. The common sites of metastasis are respectively lymph nodes, lungs, livers, and adrenal glands in order of frequency. The presence of poorly differentiated eosinophilic cells in a characteristic fibro-inflammatory stroma is seen in histological examination. The origin and pathogenesis of RMC are unclear. The radiographical and pathological findings suggest that RMC probably originates in the calyceal epithelium in or near the renal papillae, which could be the result of chronic ischemic damage in the renal papillae epithelium by sickled erythrocytes. Positivity of VEGF and HIF-1α supports the chronic hypoxia that may be caused in the pathogenesis of RMC. Other factors such as genetic or environmental factors are important. Although hemoglobinopathy is very common, RMC is very rare. An understanding of the molecular and genetic factors of this rare disease is important for its prevention and treatment. We herein describe an adult Turkish patient, who presented with hematuria. The diagnosis was RMC after pathological examination
The morphological and biochemical investigation of prenatal electromagnetic wave effects on urinary bladder in rats
Objectives: The aim of the study was to investigate the effects of
digital cellular system (DCS) 1800-MHz radiation of a common
digital mobile phone which has the highest specific absorption rate
value of 1.79 W/kg on the urinary bladders of male rats.
Materials and Methods: Rats exposed to electromagnetic
wave (EMW) emmited by mobile phones on stand-by (Stand-by
Fetal Group) or discontinious transmission mode (EMW Fetal
group), 2 hours per day, from embryonic day 14 until parturition
or until postnatal day 60 (Stand-by Fetal Group). The urinary
bladders of the animals in experimental groups were removed at
postnatal day 60 and prepared for light and electron microscopical
investigation. The barrier function of urothelium was evaluated
using zonula occludens 1 and E-cadherin immunohistochemistry
and ruthenium red staining for transmission electron microscopy.
Oxidative damage were evaluated by biochemical techniques.
Results: EMW wave group showed desquamation of urothelial
cells, increased number of mast cells, degeneration of tight junctions and
dilatation of intercellular space. Finally, increase in the malondialdehyde
and decrease in the glutathione levels were observed in all experimental
groups when compared to Those in the control group.
Conclusion: Exposure intensity and time length correlate with
adverse effects in developing period of the urinary bladder. These
changes may lead to urinary bladder inflammatory disorders

Effects of Intensive Cell Phone (Philips Genic 900) Use on the Rat Kidney Tissue
Purpose: To investigate effects of electromagnetic radiation (EMR) emitted by cell phones on therat kidney tissue.Materials and Methods: Twenty-one male Albino rats were divided into 3 groups, each comprising7 rats. Group 1 was exposed to a cell phone in speech mode for 8 hours/day for 20 days andtheir kidneys were removed. Group 2 was exposed to EMR for 20 days and then their kidneys wereremoved after an interval of 20 days. Cell phone used in the present study was Philips Genie 900,which has the highest specific absorption rate on the market.Results: Light microscopic examination of the kidney tissues obtained from the first group of ratsrevealed glomerular damage, dilatation of Bowman’s capsule, formation of large spaces betweenthe tubules, tubular damage, perivascular edema, and inflammatory cell infiltration. The mean severityscore was 4.64 ± 1.7 in group 1, 4.50 ± 0.8 in group 2, and 0 in group 3. While there was nosignificant difference between group 1 and group 2 (P > .05), the mean severity scores of groups 1and 2 were significantly higher than that of the control group (P = .001 for each).Conclusion: Considering the damage in rat kidney tissue caused by EMR-emitting cell phones,high-risk individuals should take protective measures
The effects of electromagnetic waves emitted by the cell phones on the testicular tissue
Objectives: Various risks have emerged in parallel to the rapidly increasing use of cell phones. Herein we studied the effects of cell phone emitted electromagnetic waves (EMW) on rat testes. Material and Methods: Twenty one adult male Albino rats were grouped into 3 groups each consisting of 7 rats. The first group was exposed to EMW on talk mode for 8 hours per day for 20 days and then their testes were extracted. The testes of the second group were extracted after 20 days of whole day EMW exposure. The third group was the control group. For the statistical analysis Mann- Whitney U analysis was performed. Results: At light microscopic examination of the testicular tissue, the existence of a high number of immature cells in the lumen of the seminiferous tubule in addition to the normal seminiferous tubules, besides irregular tubules with a reduction in the spermatogenic cell lines and tubules without lumen were observed in groups 1 and 2. Histopathological alterations were scored as 0 = none, 1 = low, 2 = medium, 3 = serious. The average scores of the three groups were found to be 4.25 ± 1.5 for the group 1, 4.33 ± 3.9 for the group 2 and 0.37 ± 1.1 for the group 3 respectively. As a result of the statistical evaluation, group 1 and group 2 had significantly higher scores than the control group (p = 0.001). Conclusion: Infertility is one of the current problems of today due to a rapid increase in its incidence and cost. The negative effects of the EMWs on the testis should be taken into account and the necessary measures should be taken for prevention
