Schizophrenia is a severe psychiatric disorder with about 1% prevalance. NMDA receptor antagonists such as Phencyclidine (PCP) and MK-801 are commonly used for modeling schizophrenia in rodents. In literature, despite of the concensus about subchronic PCP administration (commonly 7 days, bi-daily administration followed by a 1 week washout period), there are different subchronic administration regimens for MK-801 beside 7 days, bidaily (MK-801-7), such as 14 days (MK-801-14) daily or 28 days daily injections. In this study, we aimed to compare two prevalant MK-801 models (MK-801-7 and MK-801-14, 0.2 mg/kg) in both behavioural and molecular changes. Wistar Hannover rats grouped as control (n=10), MK-801-14 (n=8) and MK-801-7 (n=8). Prepulse inhibition of acustic startle response (PPI), novel object recognition test (NORT), social interaction (SI) and Morris's water maze (MWM) tests were used for behavioural analyzes while real time polimerase chain reaction (Rt-PCR) was conducted for molecular analyzes of glutamic acid decarboxilase 67 (GAD67) and parvalbumin. Our results showed decreased PPI in MK-801-14 and MK801-7 groups. Moreover, in both models platform finding latencies were increased and swimming time in platform area was decreased in MWM. MK-801-14 and MK-801-7 reduced following and raised avoiding behaviours in SI. In Rt-PCR, GAD67 mRNA levels were decreased by MK-801-14 and MK-801-7 administrations. However, only MK-801-7 decreased discrimination index in NORT and parvalbumin mRNA levels. In this study, it has been showed that although MK-801-14 and MK-801-7 administrations revealed smiliar schizophrenia like symptoms in rats, MK-801-7 has partial superiories in certain aspects.

Cyclophosphamide [CP], as alkylating agents has side effects such as nephrotoxicity. Cerium oxide nanoparticles [nanoceria; NC], as an antioxidant, are effective at reduction oxidative stress. This study evaluated the protective effect of nanoceria in nephrotoxicity induced CP. 32 BALB/c mice were randomly divided into four equal groups. Control, NC, CP and NC+CP. NC and CP injected intraperitoneally respectively in dose of 100 μg/kg for 3 days and 200 mg/kg single dose on 3th day of study. Two days after the final treatment, histochemical, serum biochemical, histopathological and immunohistochemical examinations were performed for determination effects of NC on nephrotoxicity. Oxidative stress and renal injury induced in CP treated mice were proved by the significantly elevation of urea and creatinine and alteration in oxidative stress markers [MDA and GSH levels]. Consequently, histopathological changes and apoptosis were markedly increased. NC was able to reduce MDA, urea , creatinine and increase GSH content. In addition, NC pretreatment could alleviated immunoreactivity of caspase-3. NC revealed a strong antioxidant in nephrotoxicity following CP treatment. This study suggests that NC through antioxidant and antiapoptotic properties have protective effect against CP-induced nephrotoxicity.

A key challenge in cancer treatment is the wide range of cancer cells’ behavior towards chemotherapy and treatment procedures, which makes the outcomes of treatment often unpredictable, accompanied by cancer resistance and recurrence. One underlying reason is that tumor is a heterogeneous tissue. The cells within a tumor are at different metabolic states and hence behave differently from another and towards the chemotherapeutics. Many of the cells in the inner layers of a tumor lack an appropriate growth condition. However, upon tumor shrinkage, they can regrow and finally cause tumor resistance or recurrence. In the current study, for the first time, long term effects of different levels of metabolic stress on human ovary cancer cell line, A2780, is reported. In this in vitro model, the cells exposed to 10% serum were considered as control and metabolic stress was induced at 0.5, 0.25 and 0% serum for 1-6 days. In this 6-day period, cells’ morphology changes, size, cell cycle, mitochondrial function and protein content was measured at 24-hour intervals. Also, cells ability to recur was assessed with the above tests in a 24-hour release in 10% serum. The results of this study showed that A2780 cells show resistant features against metabolic stress and this longterm stress does not stop cells recurrence. These results indicate that in order to have a successful tumor treatment, a modified chemotherapy procedures against different types of cells laying within one tumor is required.

The main goal of this study was to investigate the effect of exposure time and smoking habit on arsenic levels in biological samples of workers occupationally exposed to metals in comparison with non-occupational residents in Turkey. Blood, urine and hair samples were collected from 95 metal workers at Ankara Occupational Diseases Hospital, Turkey. Similarly, 94 hair samples were taken from controls. Arsenic levels in biological samples were measured using Graphite Furnace Atomic Absorption Spectrometry (GFAAS) equipped with Zeeman background correction and Hydride Generation Atomic Absorption Spectrometry (HGAAS). In metal workers; mean hair-arsenic levels of the smokers group (2.05 ±1.97 mg As/kg) was found to be significantly higher than the mean of the hair-arsenic levels of non-smokers group 1.80±1.79 mg As/kg (p<0.05). Mean hair-arsenic levels of exposure time group (4-10 years) was found (2.34±2.21 mg As/kg) to be significantly higher than the arithmetic mean of exposure time group (1-3 years) (1.39 ±1.25 mg As/kg, p<0.01). As for the control group, mean of hair-arsenic levels in the smokers group (0.133 ±0.012 mg As/kg) was found to be significantly higher than the mean of the hair-arsenic levels of non-smokers group (0.101±0.006 mg As/kg, p<0.05). In addition, mean hair arsenic level in metal workers (1.81 ±1.79 mg As/kg) was found significantly higher than mean hair arsenic level in control group (0.115 ±0.006 mg As/kg, p=0.00). Smoking increased the hair arsenic levels significantly both in metal workers and controls. The hair arsenic levels significantly enhanced with ascending exposure time. In addition, metal workers had significantly higher hair arsenic levels than controls. However, there was no significant effect detected in terms of urine and blood arsenic levels.

ABSTRACT: Ulcers that develop due to alcohol consumption are frequently confronted. The aim of this study was to investigate the protective effects of silk fibroin on the pro-apoptotic and anti-apoptotic protein expression levels on ethanol induced-ulcer models in rats. For three consecutive days, orogastrically either silk fibroin or saline were given to rats. On the 4th day, animals were deprived of food but allowed free access to water for 24 h before the experiment. While control groups were treated with only physiological saline, the ulcer groups were treated orally either with saline or silk fibroin groups. For ulcer induction, 1 ml of absolute ethanol by gavage were given to both group. Firstly, intracardiac blood was taken at 60 min of EtOH or saline administration and immediately animals were decapitated. In blood samples, the amount of TNF-, IL-1β were analysed whereas in stomach tissues, the levels of MDA, GSH, and MPO activity and the expression levels of bcl-2, Bax, caspase-3 and -9 were determined. In ulcer groups, the amount of TNF- , IL-1β, MDA, MPO, caspase-3 and caspase-9 were found to be significantly higher compared to control groups whereas in GSH, Bcl-2/Bax were found to be lower (p < 0.005). In treatment groups it is observed that silk fibroin recovers the amount of TNF-, IL 1-β, MDA, MPO, GSH, caspase-3, caspase-9, and Bcl2/Bax. In conclusion, for the treatment of the gastric ulcer SF thought to be very efficient therapeutic agent.

We compared different stress conditions on brain BDNF levels, in rats exposed to social isolation test (SIT) and predator scent tests (PST). BDNF expression in the frontal cortex, hippocampus, and amygdala was compared, and effects of chronic fluoxetine (FLU) treatment were evaluated. Rats were exposed to SIT and PST for one month. FLU was given (5 mg/kg/day, ip) throughout stress procedures. Controls, stress, and treatment groups were evaluated in elevated plus maze, anxiety scores were calculated. BDNF expression was determined by Western blot. SIT and PST induced anxiety in both sexes, females had greater anxiety scores than males (p<0.05). FLU restored anxiety scores in both sexes (p<0.01) in both tests. Male and female rats exhibited reduced cortical BDNF levels in SIT (p<0.001). PST reduced cortical BDNF in females, but increased in males. Hippocampal BDNF expression was lowered in SIT (p<0.01) and PST (p<0.001) in both sexes. Female rats had 40% lower BDNF expression than males in the amygdala in SIT. FLU did not restore cortical BDNF in females in both tests, but reduced increased BDNF levels in males in PST (p<0.001). FLU did not restore reduced brain BDNF in males in the hippocampus and amygdala, but restored in hippocampus, in females. Our findings indicate that sex differences must be considered in studies related to mood disorders of animal models, and suggest that BDNF expression in different brain regions are altered differentially in a gender-dependent manner in rats. Antianxiety effect of FLU is not mediated through increasing BDNF activity in cortex in both genders. Increased BDNF in hippocampus and amygdala may reflect antidepressant effect of FLU in female rats, but not in males.
