Glioblastoma multiforme (GBM) is the most malignant brain cancer that causes high mortality in humans. It responds poorly to the most common cancer treatments, such as surgery, chemo- and radiation therapy. Temozolomide (TMZ) is an alkylating agent that has been widely used to treat GBM; resistance to this drug is often found. One unexplored possibility for overcoming this resistance is a treatment based on concomitant exposure to electromagnetic fields (EMF) and TMZ. Indeed, many evidences show that EMF affects cancer cells and drug performance. In this study, we evaluated the potential synergistic effect of 100 μM TMZ and EMF (100 Hz, 100 G) on two human glioma cells line, i.e., U87 and T98G above single treatments, TMZ or EMF. Co-treatment synergistically enhanced apoptosis in U87 and T98G cells, by increasing the expression of P53, Bax, and Caspase-3 and decreasing that of Bcl-2 and Cyclin-D1. We also observed an increase in reactive oxygen species (ROS) production and the overexpression of the heme oxygenase-1 (HO-1) gene in comparison to controls. In conclusion, since EMF enhanced the apoptotic effect of TMZ, possibly through a redox regulation mechanism, the TMZ/EMF combination may be effective for glioma cancer treating. Further studies are needed to reveal the action mechanism of this possible novel therapeutic approach. © 2017 Elsevier Masson SAS

Diabetes mellitus (DM), the most common metabolic disease, might affect different organs such as male reproductive system. Experiments have shown that n-3 fatty acids could improve male reproductive function. Present study was performed to examine the effects of omega3 on sperms and testicular parameters in diabetic mice. Adult NMRI male mice were randomly divided into intact and diabetic groups (n=8). Streptozotocin-induced diabetic animals were divided into 4 groups of diabetic-saline (Dia-Sa), diabetic-insulin (Dia-Ins), diabetic-omega3 (Dia-omg3), and diabetic-insulin-omega3 (Dia-Ins-omg3). Following confirmation of diabetes, different treatments including 3 U/100 g insulin subcutaneously and 400 mg/kg omega3 orally were administered, where applicable according to the treatment groups. Thirty-five days later, the sperm number, motility, progression, and normal morphology were determined. Also, testes diameters and structure including germinal epithelium thickness, seminiferous tubule diameters, Leydig cell number, and testosterone level were assessed. Sperm number, viability, fast motility, testes volume, and serum testosterone level decreased insignificantly in the Dia-Sa group compared with the intact animals. Neither insulin replacement nor omega3 administration could significantly improve the outcome. We might conclude that short periods of diabetes could not significantly affect the male reproductive function. In addition, insulin replacement and/or omega-3 supplementation does not have any profound effects on male reproductive system. © 2017 Atefe Yaghoubi et al.

STUDY DESIGN.: This study measured the frequency of lumbar intervertebral disc nucleus pulposus microscopic calcification and angiogenesis in adult patients undergoing discectomy compared to normal cadavers. OBJECTIVE.: The results were compared to determine the relationship between disc microscopic calcification with disc degeneration type, histopathological angiogenesis, patients' age, gender, and duration of symptoms. SUMMARY OF BACKGROUND DATA.: True frequency of microscopic calcification in normal or degenerated lumbar discs have not been fully defined nor linked to disc degeneration type and angiogenesis. Some studies demonstrated that angiogenesis and calcification are related to each other in several another tissues. METHODS.: The frequency of microscopic calcification in specimens of disc nucleus pulpous obtained from 2 groups were measured: specimens were obtained during surgery from 90 consecutive patients of 15 to 50 years old suffering from disc herniation in single level of L4-L5 or L5-S1 between 2005 and 2006, 60 additional specimens of lumbar disc nucleus pulposus were obtained from normal cadavers of the same ages. Calcification was determined microscopically by Von Kossa staining and angiogenesis by H/E, and type of degeneration radiologically by Modic classification. RESULTS.: Frequency of microscopic calcification was significantly higher in degenerated disc than normal cadaveric (54.4% vs. 6.7%) and was higher in Modic type III than type I (III: 95.0%, II: 57.4%, I: 13.0%), also prevalence of angiogenesis was significantly higher in patients than cadaveric discs (41.0% vs. 6.7%) and in calcified than noncalcified discs (59.2% vs. 19.5%) (P < 0.001). There was no relationship between disc calcification and patients' gender and level of discectomy. CONCLUSION.: Disc nucleus pulposus microscopic calcification is a common event occurring in adult patients suffering from lumbar disc herniation. Mechanisms that link disc degeneration, angiogenesis, and calcification remain a focus for further researches that may be useful in future medical treatments before surgical treatment of lumbar disc herniation. © 2010, Lippincott Williams & Wilkins.

Background and Aims: Hepatocellular carcinoma (HCC) is a well-known consequence of chronic liver disease (CLD). The aim of this study was to extract the HCC incidence rate in the province of Kerman, located in southern part of Iran, and compare the data with other parts of the country. Materials and Methods: All medical records related to HCC were collected through hospitals or outpatient services in public or private centers. The records of all oncology, radiotherapy, and pathology centers in Kerman province were actively searched between 1999 and 2006. The annual incidence of HCC around the country was calculated, using the national cancer registry database provided by the Health Ministry of IR Iran from 2005 to 2006. Using Stata version 8, the crude and age-sex-standardized annual incidence rates were computed. Results: The crude annual incidence rates of HCC per 100,000 persons in Kerman and Iran were 0.522 (95% CI = 0.238- 0.88) and 0.199 (95% CI = 0.167-0.234), respectively. When adjusting for age and sex, the annual incidence rates of HCC in Kerman and Iran were 0.7 (95% CI = 0.4-1.1) and 0.2 (95% CI = 0.2-0.3) per 100,000 persons, respectively (P<0.01). The mean age of patients in Kerman was around 5.5 years younger than other parts of Iran (56.17 ± 18.32 years versus 61.68 ± 14.62 years; P=0.004). Conclusions: In general, the incidence of HCC is not very high in Iran; however, the higher incidence of HCC in Kerman and also the lower age of onset mandates further research to detect HCC's risk factors in this part of country.

The prevalence of cigarette and alcohol consumption is high among young adult males during the reproductive period. The current study aimed to evaluate the impact of concurrent chronic administration of nicotine and ethanol on the quality of sperm in the rat. Fifty healthy Wistar male rats were randomly divided into five groups (n = 10) and were given the following for a period of 50 days: ethanol (E), nicotine (N), ethanol and nicotine (E/N); the control group (C) and an intact (I) group. Body weight as well as the weight, volume and dimensions of the testes and the weight of the cauda epididymidis and vas deference were measured. The concentration, motility, viability and membrane integrity of sperm were also assessed. There were no significant differences between body weight and all testis parameters including weight, volume and dimensions. The concentration and motility of sperm in the E/N group was significantly reduced compared with the control group (P < 0.01). Nevertheless, only a marginally significant decrease in sperm viability was found in the E/N group compared with the control group. The study indicates that concurrent chronic administration of ethanol and nicotine may disturb male reproductive function. © 2012 Blackwell Verlag GmbH.

Study Design: A retrospective study. Purpose: The aim of this study was to evaluate the effects of delayed hypothermia on spinal cord injuries in rats. In addition, the effect of methylprednisolone on therapeutic window of hypothermia was evaluated. Overview of Literature: Several studies have demonstrated that early hypothermia is the most effective neuroprotective modality. However, delayed hypothermia seems to be more practical for patients with traumatic spinal cord injuries. A combination of hypothermia and other neuroprotective methods, such as using methylprednisolone, may help extend the therapeutic window of hypothermia. Methods: One hundred and twenty male rats were categorized into six groups. The rats in five groups were subjected to spinal cord injury using the weight drop method, followed by treatment, consisting of early hypothermia, late hypothermia, late hypothermia plus methylprednisolone, or methylprednisolone only. Biochemical tests including catalase, malondialdehyde, and superoxide level were evaluated in the injured spinal cord. Behavioral functions of the hind limb were evaluated by Basso-Battle-Bresnaham locomotor rating scale and tail-flick tests. Results: Functional and biochemical evaluation showed both early and late hypothermia had significant neuroprotective effects. The treated groups did not differ significantly from one another in the behavioral tests. Hypothermia had better biochemical results compared to methylprednisolone. Also, methylprednisolone was shown to extend the therapeutic window of delayed hypothermia. Conclusions: Hypothermia showed a significant neuroprotective effect, which can be improved with further studies optimizing the duration of hypothermia and the rewarming period. Moreover, the therapeutic effect of the delayed hypothermia can be extended by methylprednisolone. © 2015 by Korean Society of Spine Surgery.

Car accidents and gun-shot injuries are the most common causes of spinal cord injury. Five percent of those patients who have a complete spinal cord injury will experience improvement, to some extent. The lack of specific data in the literature regarding the outcome of earthquake related spinal cord injury justified us to design this study where we evaluated the neurological outcome and related factors of SCI in the Bam earthquake. We retrospectively evaluated the neurological outcome of patients with spinal cord injury who survived the Bam earthquake. In this study all patients with spinal cord injury that resulted from the Bam earthquake who registered in the Welfare Organization of Kerman were studied. The neurological conditions of patients eighteen months after the earthquake were compared with their neurological conditions at the time of the earthquake. A total of 17 (23.9%) patients with grade A impairment based on ASIA impairment Scale (AIS) at the time of the earthquake had significant neurological recovery. In addition, younger patients had better neurological outcomes. Those who had fracture dislocations had a worse outcome. Spinal cord injuries that are due to earthquakes have a better neurological outcome in comparison with other causes of this injury. The patients' ages and types of spinal fractures were significantly related to the neurological outcome.

The aim of this study was to evaluate whether vitrification is an effective cryopreservation method for storage of human umbilical cord mesenchymal cells (HUCMs). HUCMs were vitrified using a two step method. The viability of vitrified HUCMs (v-HUCM) and nonvitrified HUCMs (n-HUCM) was determined by Trypan Blue staining. The expression of several markers was evaluated using flow cytometry. The osteogenic, adipogenic and chondrogenic differentiation potential of v-HUCMs and n-HUCMs was determined. The postwarming viability of HUCMs was 95.54 ± 2.30. The expression of surface antigens (strong positive for CD44, CD90 and CD 105; negative for CD34 and CD45) was similar in the above mentioned groups. The v-HUCM cells retained ability to differentiate into osteoblasts, adipocytes and chondrocytes under appropriate culture conditions. The analysis of these results showed that vitrification is a reliable and effective method for cryopreservation of human umbilical cord mesenchymal cells. © CryoLetters.

Background aims: Vitrification as an advanced cryopreservation method is recommended for cell storage toward future applications. The purpose of this report was to appraise whether gametogenic potential of these cells is altered by vitrification. Methods: A two steps method was applied for hUCM cells vitrification. An n-hUCM group of hUCM cells served as control. In order to differentiation of hUCM cells into male germ cells, the cells were induced by retinoic acid, testosterone and testicular-cell-conditioned medium. To evaluate induced hUCM cells toward germ cells, we used immunocytochemistry and karyotyping methods. Results: v-hUCM cells similar to n-hUCM cells formed flat cells after gametogenic induction, and showed protein expression of germ-cell-specific markers DAZL, VASA (DDX4) and SCP3. Karyotyping pattern remained unchanged in the either groups. Conclusions: The analysis of these results demonstrates that vitrification does not alter differentiation potential of hUCMs to male germ like cells. These results may set an in vitro pattern to study germ-cell formation from hUCM cells and also as a potential source of sperms for male infertility. © 2014 International Society for Cellular Therapy.

Study Design: Prospective study. Purpose: We compared the effects of two methods of epidural steroid injection in patients with recurrent disc herniation. Overview of Literature: To our knowledge, there is no previous report of such a comparison in these patients. Methods: The study was performed with 30 patients with relapsed lumbar disc herniation whose pain was not relieved by conservative remedies. The patients were divided into two groups, each of 15 patients, and entered the study for caudal or transforaminal injections. The degree of pain, ability to stand and walk, and the Prolo function score were evaluated in both groups before the injection and 2 months and 6 months after the injection. Results: The degrees of pain reduction in the caudal injection group in the second and sixth months were 0.6 and 1.63, respectively, and in the transforaminal injection group were 1.33 and 1.56, respectively. The difference between the two methods was not statistically significant. Similarly, no other evaluated criterion showed a significant difference between the methods. Conclusions: In the current study, the caudal and transforaminal steroid injection methods showed similar outcomes in the treatment of relapsed lumbar disc herniation. However, more detailed patient categorizing may help in finding possible subgroups with differences.
