Early administration of milrinone ameliorates lung and kidney injury during sepsis in juvenile rats.

BACKGROUND: A sepsis model was created, induced by cecal ligation and puncture (CLP), in juvenile rat groups. Milrinone (MIL), which is known to have a modulatory effect on pro-inflammatory cytokines, was administered to the designated rat groups in the early period before severe sepsis developed. The study was aimed at investigating the possible protective effects of milrinone on the lung and kidney tissues of rats in the late phase of sepsis. METHODS: The rat pups were divided into seven groups with six animals in each group: (1) healthy rats who received no drug; (2) CLP-S12 (sacrificed at hour 12); (3) CLP-S24 (sacrificed at hour 24); (4) CLP-MIL1-S12 (administered with 0.5 mg/kg milrinone at hour 1 and sacrificed at hour 12); (5) CLP-MIL1-S24 (administered with 0.5 mg/kg milrinone at hour 1 and sacrificed at hour 24): (6) CLP-MIL12-S24 (administered with 0.5 mg/kg milrinone at hour 12 and sacrificed at hour 24), (7) and CLP-MIL1,12-S24 (administered with 0.5 mg/kg milrinone at hours 1 and 12 and sacrificed at hour 24). RESULTS: Significant differences were found between the early and late administration of milrinone in terms of both molecular and histopathological results. The results showed that the tissues were significantly preserved in the groups in which milrinone had been started in the early period compared to the sepsis control groups and the groups in which milrinone had been started in the late period. CONCLUSIONS: In addition to the positive inotropic effects of milrinone, its immunomodulatory properties that result in decreased cytokine storm can be beneficial during early period of sepsis.

A comparison of phenomenological, clinical and familial psychiatric features of pediatric OCD and trichotillomania.

OBJECTIVES: Although trichotillomania (TTM) is classified in the obsessive-compulsive disorders (OCD) chapter of the DSM-5, several studies showed that it has several differences. The aim of this study was to examine the phenomenology, comorbidity, and family psychiatric characteristisc of childhood TTM and OCD. METHODS: This study compared youth ages 6-17 years with a primary diagnosis of TTM (n = 63) to those with primary OCD (n = 65) on clinical and familial psychiatric characteristics. RESULTS: In our study, the findings showed that family history of schizophrenia (42.3%) was higher among patients with TTM than the OCD group, while the history of OCD (55.8%) in the family was significantly higher among the OCD group (p < 0.001). The behaviour of plucking eyebrows was significantly higher among patients with TTM comorbid OCD than patients with only trichotillomania. TTM patients with comorbid OCD had one-dimensional symptom distribution than the presence of the OCD-only group, and the severity of OCD was lower. The incidence of pathological doubting was higher among the TTM group with comorbid OCD, than those with only OCD diagnosis. CONCLUSIONS: These findings support significant differences between OCD and TTM. Differences between OCD and TTM may reflect differences in underlying psychobiology, and may necessitate contrasting treatment approaches.KEYPOINTSWe aimed to compare the trichotillomania in itself and in the presence of OCD with the OCD group.Even if OCD accompanied trichotillomania, OCD symptom dimensions and severity were found to be lower than in the OCD-only group.Trichotillomania is a heterogeneous disorder with different dimensions besides the OCD spectrum.

Neuroprotective effect of roflumilast under cerebral ischaemia/reperfusion injury in juvenile rats through NLRP-mediated inflammatory response inhibition.

This study aims to investigate the protective effect of roflumilast, a phosphodiesterase (PDE)-4 enzyme inhibitor, and demonstrate its possible role in the development prevention of cerebral ischemia/reperfusion injury (CI/RI) after stroke induced by carotid artery ligation in juvenile rats. The rats were randomly divided into five groups: healthy group without any treatment, healthy group administered with 1 mg/kg roflumilast, CI group not administered with roflumilast, CI group administered with 0.5 mg/kg roflumilast, and CI group administered with 1 mg/kg roflumilast. In the CI groups, reperfusion was achieved 2h after ischemia induction; in the roflumilast groups, this drug was intraperitoneally administered immediately after reperfusion and at the 12th hour. At the end of 24h, the rats were sacrificed and their brain tissues removed for examination. The mRNA expressions obtained with real-time PCR of IL-1ß, TNF-α, and NLRP3 significantly increased in the CI/RI-induced groups compared with the control group, and this increase was significantly lower in the groups administered with roflumilast compared with the CI/RI-induced groups. Moreover, ELISA revealed that both IL-1 ß and IL-6 brain levels were significantly higher in the CI/RI-induced groups than in the controls. This increase was significantly lower in the groups administered with roflumilast compared with the CI/RI-induced groups. Histopathological studies revealed that the values closest to those of the healthy group were obtained from the roflumilast groups. Nissl staining revealed that the Nissl bodies manifested normal density in the healthy and roflumilast-administered healthy groups, but were rare in the CI/RI-induced groups. Roflumilast treatment increased these decreased Nissl bodies with increasing doses. Observations indicated that the Nissl body density was close to the value in the healthy group in the CI/RI-induced group administered with 1 mg/kg roflumilast. Overall, roflumilast reduced cellular damage caused by CI/RI in juvenile rats, and this effect may be mediated by NLRP3.

The prevalence of childhood psychopathology in Turkey: a cross-sectional multicenter nationwide study (EPICPAT-T).

AIM: The aim of this study was to determine the prevalence of childhood psychopathologies in Turkey. METHOD: A nation-wide, randomly selected, representative population of 5830 children (6-13 years-old) enrolled as a 2nd,3rd or 4th grade student in 30 cities were evaluated for presence of a psychiatric or mental disorder by a Sociodemographic Form, Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL), and DSM-IV-Based Screening Scale for Disruptive Behavior Disorders in Children and Adolescents scales. Impairment criterion was assessed via a 3 point-Likert scale by the parent and the teacher independently. RESULTS: Overall prevalence of any psychopathology was 37.6% without impairment criterion, and 17.1% with impairment criterion. Attention-deficit hyperactivity disorder was the most frequent diagnosis, followed by anxiety (19.5% and 16.7% without impairment, 12.4% and 5.3% with impairment, respectively). Lower education level and presence of a physical or psychiatric problem of the parents were independent predictors of any psychopathology of the offspring. CONCLUSION: This is the largest and most comprehensive epidemiological study to determine the prevalence of psychopathologies in children and adolescents in Turkey. Our results partly higher than, and partly comparable to previous national and international studies. It also contributes to the literature by determining the independent predictors of psychopathologies in this age group.

Serum Cytokine Profiles of Children with Obsessive-Compulsive Disorder Shows the Evidence of Autoimmunity.

BACKGROUND: Previous reports have described an association between autoimmunity and primary obsessive compulsive disorder. This study aimed to investigate any differences in the levels of T helper 1, 2, and 17 effector cell cytokines between obsessive compulsive disorder patients and the control group. METHODS: The study included 34 children (23 males, 11 females), aged between 7 and 17 years, with a diagnosis of obsessive compulsive disorder prior to receiving treatment. The control group consisted of age- and gender-matched children. Study participants were assessed using the Kiddie Schedule for Affective Disorders and Schizophrenia, Present and Lifetime version, Children's Yale Brown Obsession Compulsion Scale, and Children's Depression Inventory. Cytokine serum concentrations were measured using the BD Cytometric Bead Array Human Th1/Th2/Th17 Cytokine Kit. RESULTS: Interleukin-17A, tumor necrosis factor-α, and interleukin-2 levels were significantly higher in obsessive compulsive disorder patients, However, there was no correlation between T helper 1 and 17 cytokine profiles in the obsessive compulsive disorder group. The duration and severity of obsessive compulsive disorder symptoms were not significantly associated with interleukin-17A, interferon-gamma-γ, interleukin-10, interleukin-6, interleukin-4, and interleukin-2 levels. Interestingly, a negative correlation was found between tumor necrosis factor-α levels and Clinical Global Impression scores. CONCLUSIONS: These findings suggest, in some cases, obsessive compulsive disorder may develop on a background of autoimmunity, and interleukin-2, tumor necrosis factor-α, and interleukin-17A may play a role in these autoimmune processes. Therefore, we believe it is important to investigate for obsessive compulsive disorder symptoms in patients with autoimmune disease and, conversely, autoimmune diseases in obsessive compulsive disorder patients.

Oxidative Stress and DNA Damage in Untreated First-Episode Psychosis in Adolescents.

OBJECTIVE: Oxidative stress has been reported to play a role in the psychopathology of schizophrenia, though only a few studies have investigated the relationship between early-onset schizophrenia and oxidative stress. The aim of the present study is to evaluate the level of oxidative stress and the presence of DNA damage in first-episode psychosis (FEP) in adolescents. METHODS: This study was conducted in the Department of Child Psychiatry of the Dicle University Hospital. It included 20 adolescent patients (age 11-17 years) with psychosis (acute psychosis, schizophreniform disorder, or schizophrenia) according to DSM-IV criteria who had received no previous psychiatric therapy (patient group) and 20 age/gender-matched healthy adolescents (control group). Structured psychiatric interviews [Kiddie Schedule for Affective Disorders and Schizophrenia, Present and Lifetime Version (K-SADS-PL) and Positive and Negative Symptom Scale (PANSS)] were conducted on the patients, and the Clinical Global Impressions (CGI) scale was used to evaluate the severity of disease. Glutathione peroxidase (GPx), superoxide dismutase (SOD), coenzyme Q (CoQ), and 8-hydroxy-2-deoxyguanosine (8-OHdG) levels were determined using the ELISA method and commercial ELISA kits. RESULTS: The mean age was 14.5 ± 1.6 years in the FEP group (male-to-female ratio: 8/12) and 14.4 ± 1.5 years in the control group (male-to-female ratio: 8/12). There were no differences between the patient and control groups in terms of SOD, GPx, or 8-OHdG values (p > 0.05). CONCLUSIONS: This study on DNA damage and oxidative stress in FEP in adolescents had a small sample size, and our data suggest that oxidative stress is associated with a chronic disease course rather than being an early sign of early-onset schizophrenia.

The Levels of Cortisol, Oxidative Stress, and DNA Damage in the Victims of Childhood Sexual Abuse: A Preliminary Study.

In this study we aimed to investigate serum cortisol, oxidative stress, and DNA damage in children who are sexual abuse victims. The study included 38 children who sustained child sexual abuse and 38 age- and gender-matched children who did not have a history of trauma. Cortisol levels reflecting the status of the hypothalamic-pituitary-adrenal axis, anti-oxidant enzymes glutathione peroxidase, superoxide dismutase, natural anti-oxidant coenzyme Q, and 8-hydroxy-2-deoxyguanosine as the indicator of DNA damage were analyzed in serum samples using the enzyme linked immunosorbent assay method. Cortisol levels were significantly higher in the child sexual abuse group compared to the control group. There were no significant differences between the groups in terms of oxidative stress and DNA damage. Cortisol and 8-hydroxy-2-deoxyguanosine levels decreased as the time elapsed since the sexual abuse increased. Coenzyme Q level was lower in victims who sustained multiple assaults than in the victims of a single assault. Cortisol and superoxide dismutase levels were lower in the victims of familial sexual abuse. Decreases in cortisol and 8-hydroxy-2-deoxyguanosine levels as time elapsed may be an adaptation to the toxic effects of high cortisol levels over a prolonged period of time. Child sexual abuse did not result in oxidative stress and DNA damage; however, some features of sexual abuse raised the level of oxidative stress.

Lower Brain-Derived Neurotropic Factor Levels in Untreated Adolescents With First-Episode Psychosis.

OBJECTIVE: Brain-derived neurotropic factor (BDNF) is known to play a role in the pathogenesis of schizophrenia. However, the relationship between early onset schizophrenia and BDNF has not been extensively studied. The aim of the study was to compare the levels of BDNF between adolescent patients with first-episode psychosis (FEP) and the healthy control subjects. METHOD: The study was conducted in the Department of Child Psychiatry at Dicle University. A total of 26 adolescent patients aged between 11 and 17 years who had not received previous therapy and whose conditions were diagnosed with psychosis according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, and 26 age- and sex-matched healthy adolescent control subjects were included. Kiddie Schedule for Affective Disorders and Schizophrenia, Present and Lifetime version, and the Positive and Negative Symptom Scale were conducted with all participants. The clinical global impression was used to evaluate disease severity. The BDNF levels were measured in the serum by enzyme-linked immunosorbent assay method. RESULTS: The mean (SD) age was 14.6 (1.6) years in both FEP group (male/female, 11/15) and the control group (P > 0.05). The FEP group had significantly lower serum BDNF levels (2.0 ± 1.9 ng/mL) compared with the control group (3.4 ± 3.0 ng/mL, P = 0.03). There was no significant relationship between BDNF concentration and the Positive and Negative Symptom Scale (positive and negative scores) scores (r = -0.14, P = 0.74 and r = 0.49, P = 0.22, respectively). There was no significant relationship between the duration of untreated psychosis and serum BDNF levels (r = -0.22, P = 0.32). CONCLUSIONS: High incidence of schizophrenia in patients with FEP suggests a relationship between BDNF levels and the pathogenesis of schizophrenia. We suggest that BDNF may be a useful neurobiological marker of early onset schizophrenia.

Examining the levels of BDNF and cortisol in children and adolescent victims of sexual abuse--a preliminary study.

BACKGROUND: Previous reports have suggested the biological and psychological effects of trauma induced by cortisol and brain-derived neurotrophic factor (BDNF). The present study compared the levels of BDNF, cortisol, and adrenocorticotropic hormone (ACTH) in children and adolescent victims of sexual abuse to those without a trauma history. METHODS: The study was conducted in the Department of Child Psychiatry at Dicle University. The study included 44 children (M/F: 12/32) aged between 8 and 17years who experienced sexual abuse with 42 age-and gender-matched children who did not have a history of trauma. Cortisol, ACTH, and BDNF levels were measured using ELISA. RESULTS: Cortisol levels were higher and BDNF levels were significantly lower in the victims of sexual abuse compared to the control group. The mean time that elapsed from the initial sexual abuse occurrence until the date of examination was 22.7±21.7months. The evaluation of the relationship between this time span and cortisol levels revealed that cortisol levels decreased with increasing time after trauma. Cortisol and BDNF levels were lower in the victims who experienced multiple sexual assaults. CONCLUSIONS: The results of the present study suggest that cortisol and BDNF could be biological molecular mediators of the effects of trauma on biological and psychological systems. This is the first report on the effects of cortisol and BDNF induced trauma in child and adolescent victims of sexual abuse.

Investigation of the effect of telmisartan on experimentally induced peripheral nerve injury in rats.

AIM: The aim of this study was to investigate the effects of telmisartan on nerve healing in a rat peripheral nerve injury model. MATERIAL AND METHOD: Thirty adult male Wistar albino rats were divided into five groups: healthy, axonotmesis, anastomosis, axonotmesis+10 mg/kg telmisartan and anastomosis+10 mg/kg telmisartan. Walking track analyses were performed 4 weeks after the surgery. The right sciatic nerves of all the animals were examined histopathologically, stereologically and molecularly. RESULTS: Many badly damaged axons were detected in the axonotmesis group, in addition to enlarged spaces between the axons. In the anastomosis group, both ir- regular and degenerated axons at different severities were observed. The sections of the telmisartan group after the axonotmesis were similar to those of the healthy group. The sections of the telmisartan group after the anastomosis were similar to those of the healthy group and the telmisartan group after the axonotmesis. Interleukin-1 beta (IL-1ß) gene expression increased in both the axonotmesis and the anastomosis groups when compared with the healthy group. Telmisartan had a significant down-regulatory effect on IL-1ß expression. Caspase-3 mRNA expression was significantly increased in the anastomosis group, and the administration of telmisartan in this group significantly decreased this rise in caspase-3 mRNA expression. As a functional outcome, telmisartan also increased the walking distance of the rats after axonotmesis and anastomosis. CONCLUSION: The histopathological, stereological, functional and molecular data suggest that telmisartan improves nerve regeneration in peripheral nerve injuries by inhibiting inflammatory cytokine IL-1ß and apoptotic caspase-3.

Relationship between anxiety, anxiety sensitivity and conduct disorder symptoms in children and adolescents with attention-deficit/hyperactivity disorder (ADHD).

Attention-deficit hyperactivity disorder (ADHD) is often comorbid with anxiety disorders and previous studies observed that anxiety could have an impact on the clinical course of ADHD and comorbid disruptive behavioral disorders (conduct disorders and oppositional-defiant disorders). Anxiety sensitivity (AS) is a different concept from anxiety per se and it is believed to represent the constitutionally based sensitivity of individuals to anxiety and anxiety symptoms. We aimed to assess the associations between anxiety, AS and symptoms of disruptive behavioral disorders (DBD) in a clinical sample of children and adolescents with ADHD. The sample consisted of 274 treatment naive children with ADHD aged 8-17 years. The severity of ADHD symptoms and comorbid DBD were assessed via parent rated Turgay DSM-IV-Based Child and Adolescent Behavioral Disorders Screening and Rating Scale (T-DSM-IV-S), Conners' Parent Rating Scale (CPRS), and Conners' Teacher Rating Scale (CTRS). AS and severity of anxiety symptoms of children were evaluated by self-report inventories. The association between anxiety, AS, and DBD was evaluated using structural equation modeling. Analyses revealed that AS social subscale scores negatively predicted symptoms of conduct disorder (CD) reported in T-DSM-IV-S. On the other hand, CD symptoms positively predicted severity of anxiety. No direct relationships were detected between anxiety, AS and oppositional-defiant behavior scores in any scales. These results may suggest a protective effect of AS social area on the development of conduct disorder in the presence of a diagnosis of ADHD, while the presence of symptoms of CD may be a vulnerability factor for the development of anxiety symptoms in children and adolescents with ADHD.

Relationship between insight level and clinical and familial features in pediatric obsessive-compulsive disorder.

OBJECTIVE: The aim of this study was to explore the relationship between insight level and clinical and familial psychiatric features of children with obsessive-compulsive disorder (OCD). METHODS: Children's Yale-Brown Obsessive-Compulsive Scale-Symptom Checklist, 11th item of the Children's Yale-Brown Obsessive-Compulsive Scale, Wechsler Intelligence Scale for Children Revised Form, Affective Disorders and Schizophrenia for School Aged Children Present and Lifetime Version 1.0, and Structured Diagnostic Interview for Diagnostic and Statistical Manual of Mental Disorders-IV Axis I Disorders were applied to 92 pediatric OCD patients. RESULTS: In this study, the prevalence of OCD in the first children of the family was high (41.3%), and low insight was significantly related with concomitant intellectual disability (p=0.003). The level of insight was high in patients with comorbid OCD spectrum disorders (p<0.001). Attention deficit and hyperactivity disorder (ADHD) was the most common psychiatric diagnosis accompanying OCD (19.5%). Among the obsession-compulsion subscales, the symmetry/hoarding was higher in males (p=0.046). OCD patients with a family history of major depressive disorder (MDD) had high ADHD comorbidity rates (p=0.038). In OCD patients, whose family had psychiatric disorders besides MDD and anxiety disorders, the diagnosis rate of intellectual disability was higher than other diagnoses (p<0.001). CONCLUSION: The sociodemographic, clinical, and familial features of pediatric OCD patients cannot be adequately clarified if the patient has limited insight. Therefore, the insight of children with OCD should be considered a range or continuity.

The Role and Antagonistic Effects of miR-16-5p in the Regulation of ADP-Ribosylation Factor-Like Tumor Suppressor Gene 1 in Lung Cancer Cells.

OBJECTIVE: ADP-ribosylation factor-like tumor suppressor gene 1 is a member of the Ras superfamily of small guanosine triphosphatases that are known to be involved in multiple regulatory pathways in the multistage development of human cancers. Also, ADP-ribosylation factor-like tumor suppressor gene 1 expression levels have been reported to be dramatically lower in both cancer cell lines and tumor tissues compared to controls. Accordingly, defects in the regulation of the ADP-ribosylation factor-like tumor suppressor gene 1 gene seems have key tumor suppressive effects in the formation and development of human cancers including lung cancer. Moreover, microRNAs regulating the expression of ADP-ribosylation factor-like tumor suppressor gene 1 have not been described previously. Accordingly, the present study aimed to reveal the influence of miR-16-5p on the regulation of ADP-ribosylation factor-like tumor suppressor gene 1 gene. MATERIALS AND METHODS: A549 lung adenocarcinoma cells were used. For the overexpression and silencing experiments of miR-16-5p synthetic microRNA mimics and inhibitors were used, respectively. Gene expression analyses were achieved with the help of quantitative real-time polymerase chain reaction. RESULTS: MiR-16-5p was identified to be predictive target of ADP-ribosylation factor-like tumor suppressor gene 1 and directly targets the expression of ADP-ribosylation factor-like tumor suppressor gene 1 as revealed by the overexpression and silencing experiments. Specifically, it was found that miR-16-5p-overexpressed A549 cells showed a decrease in ADP-ribosylation factor-like tumor suppressor gene 1 gene expression, whereas miR16-5p-suppressed cells showed an increase in expression. These findings possibly suggest that miR-16-5p is the direct regulatory microRNA that posttranscriptionally regulates the expression of ADP-ribosylation factor-like tumor suppressor gene 1. CONCLUSION: Collectively, miR-16-5p seems to be a key regulatory molecule involved in the posttranscriptional regulation of the ADP-ribosylation factor-like tumor suppressor gene 1, and it might be responsible for the downregulation of this gene in lung cancer.

Protective effects of melatonin receptor agonists on endotoxin-induced uveitis in rats.

Objectives: Melatonin has an important role in regulating a variety of physiological functions of the body. We investigated the protective effects of Agomelatine (AGO) and Ramelteon (RAME) on Endotoxin-Induced Uveitis (EIU) in rats. Materials and Methods: 70 rats were randomly divided into fourteen groups. Healthy group normal saline, (IP), Uveitis group (200 µg/kg lipopolysaccharide (LPS), SC), DEX group (200 µg/kg LPS plus 1 mg/kg dexamethasone, IP), AGO20 group received 200 µg/kg LPS plus 20 mg/kg AGO, AGO40 group received 200 µg/kg LPS plus 40 mg/kg AGO, RAME2 group received 200 µg/kg LPS plus 2 mg/kg RAME, and group RAME4 received 200 µg/kg LPS plus 4 mg/kg RAME. Each group had two subgroups: the 3rd and 24th hr. The eye tissues were collected and investigated biomicroscopically (clinical manifestations and scoring, molecularly(qRT-PCR analyses of tumor necrosis factor-α (TNF-α), vascular endothelial growth factor (VEGF), and caspase 3 and caspase 9 mRNA expression), biochemically (Superoxide dismutase activity (SOD), Glutathione (GSH), and malondialdehyde levels (MDA)) and histopathologically (staining with Harris Hematoxylin and Eosin Y). Results: Melatonin receptor agonist treatment reduced the clinical score count of ocular inflammation in the uveitic rats. TNF-α, VEGF, caspase 9, and caspase 3 levels markedly decreased in the uveitic rats. Melatonin receptor agonists significantly ameliorated fixed changes in GSH, SOD, and MDA levels. Melatonin receptor agonists also ameliorated histopathological injury in eye tissues associated with uveitis. Conclusion: Melatonin receptor agonists ameliorated the inflammatory response in EIU. These findings suggest that melatonin receptor agonists may represent a potential novel therapeutic drug for uveitis treatment.

Effect of trimetazidine against ovarian ischemia/reperfusion injury in rat model: A new pathway: JAK2/STAT3.

Objectives: Ovarian ischemia/reperfusion (I/R) is an extremely complex pathological problem that begins with oxygen deprivation, progresses to excessive free radical production, and intensifies inflammation. The JAK2/STAT3 signaling pathway is a multipurpose signaling transcript channel that plays a role in several biological functions. Trimetazidine (TMZ) is a cellular anti-ischemic agent. This study aims to investigate the effects of TMZ on ovarian I/R injury in rats. Materials and Methods: sixty four rats were divided into 8 groups at random: healthy(group1); healthy+TMZ20(group2); ischemia (I) (group 3); I+TMZ10(group4); I+ TMZ20(group5); I/R(group6); I/R+TMZ10(group7); I/R+TMZ20(group8). Vascular clamps were placed just beneath the ovaries and over the uterine horns for 3 hr to induce ischemia. The clamps were removed for the reperfusion groups, and the rats were reperfused with care to ensure that the blood flowed into the ovaries, subjecting them to reperfusion for 3 hr. TMZ was administered orally by gavage 6 and 1 hr before operations. At the end of the experiment, ovarian tissues were removed for biochemical, molecular, and histopathological investigation. Results: TMZ administration ameliorated ischemia/reperfusion-induced disturbances in GSH and MDA levels. TMZ treatment inhibited I/R-induced JAK2/STAT3 signaling pathway activation in ovarian tissues. TMZ administration also improved the increase in the mRNA expressions of IL-1ß, TNF-α, and NF-κB caused by ischemia/reperfusion injury. Moreover, TMZ treatment improved histopathologic injury in ovarian tissues caused by ischemia/reperfusion. Conclusion: TMZ treatment protected rats against ovarian ischemia/reperfusion injury by alleviating oxidative stress and inflammatory cascades. These findings may provide a mechanistic basis for using TMZ to treat ovarian ischemia-reperfusion injury.

Anti-inflammatory and antinociceptive effects of salbutamol on acute and chronic models of inflammation in rats: involvement of an antioxidant mechanism.

The possible role of ß-2 adrenergic receptors in modulation of inflammatory and nociceptive conditions suggests that the ß-2 adrenergic receptor agonist, salbutamol, may have beneficial anti-inflammatory and analgesic effects. Therefore, in this study, we induced inflammatory and nociceptive responses with carrageenan-induced paw edema or cotton-pellet-induced granuloma models, both of which result in oxidative stress. We hypothesized that salbutamol would prevent inflammatory and nociceptive responses by stimulating ß-2 adrenergic receptors and the prevention of generation of ROS during the acute inflammation process in rats. Both doses of salbutamol used in the study (1 and 2 mg/kg) effectively blocked the acute inflammation and inflammatory nociception induced by carrageenan. In the cotton-pellet-induced granuloma test, both doses of salbutamol also significantly decreased the weight of granuloma tissue on the cotton pellets when compared to the control. Anti-inflammatory and analgesic effects of salbutamol were found to be comparable with those of indomethacin. Salbutamol decreased myeloperoxidase (MPO) activity and lipid peroxidation (LPO) level and increased the activity of superoxide dismutase (SOD) and level of glutathione (GSH) during the acute phase of inflammation. In conclusion, salbutamol can decrease acute and chronic inflammation, possibly through the stimulation of ß-2 adrenergic receptors. This anti-inflammatory effect may be of significance in asthma treatment, where inflammation also takes part in the etiopathology. This study reveals that salbutamol has significant antioxidative effects, which at least partially explain its anti-inflammatory capabilities. These findings presented here may also shed light on the roles of ß-2 adrenergic receptors in inflammatory and hyperalgesic conditions.

Protective Effects of Idebenone against Sepsis Induced Acute Lung Damage.

BACKGROUND/AIMS: Sepsis is an uncontrolled systemic infection, withcomplex pathophysiology that may result in acute lung organ damage and cause multiple organ failure. Although much research has been conducted to illuminate sepsis's complex pathophysiology, sepsis treatment protocols are limited, and sepsis remains an important cause of mortality andmorbidity in intensive care units.Various studies have shown that idebenone (IDE) possesses strong antioxidant properties, which inhibit lipid peroxidation and protect cells from oxidative damage. The present study aimed to evaluate the protective effects of IDE against lung injury in a cecal ligation and puncture (CLP)-induced sepsis rat model. METHODS: Male albino Wistar rats were used. The animals were divided into a healthy control (no treatment), CLP, IDE control (200 mg/kg), and CLP + IDE subgroups (50 mg/kg, 100 mg/kg, and 200 mg/kg), with nine rats in each group.IDE was administered 1 h after CLP induction.To evaluate the protective effects of IDE, lung tissues were collected 16 h after sepsis for biochemical, immunohistochemical staining, and histopathological examination. RESULTS: IDE significantly ameliorated sepsis-induced disturbances in oxidative stress-related factors, with its effects increasing in accordance with the dose.IDE also abolished histopathological changes in lung tissues associated with CLP.Furthermore, interleukin 1 beta (IL-1ß)and tumor necrosis factor-alpha (TNF-α) immunopositivity markedly decreased in the septic rats following IDE treatment. CONCLUSIONS: IDE largely mitigated the inflammatory response in sepsis-induced lung injury by decreasing free radicals and preventing lipid peroxidation. The results suggest that IDE may represent a potential novel therapeutic drug for sepsis treatment.

Effect of Impairment on the Prevalence and Comorbidities of Attention Deficit Hyperactivity Disorder in a National Survey: Nation-Wide Prevalence and Comorbidities of ADHD.

OBJECTIVE: This study aimed to determine the prevalence and comorbidities of attention-deficit hyperactivity disorder (ADHD) by evaluating a large-scale nation-wide sample of children. METHOD: The inclusion criterion was being enrolled as a 2nd, 3rd, or 4th-grade student. A semi-structured diagnostic interview (K-SADS-PL), DSM-IV-Based Screening Scale for Disruptive Behavior Disorders, and assessment of impairment (by both parents and teachers) were applied to 5,842 participants. RESULTS: The prevalence of ADHD was 19.5% without impairment and 12.4% with impairment. Both ADHD with and without impairment groups had similar psychiatric comorbidity rates except for oppositional defiant disorder (ODD) and conduct disorder (CD) diagnoses. Impairment in the ADHD group resulted in significantly higher ODD and CD diagnoses. CONCLUSION: Even when impairment is not described, other psychiatric disorders accompany the diagnosis of ADHD and may cause impairment in the future. Impairment in the diagnosis of ADHD significantly increases the likelihood of ODD and CD.

The Effects of Agomelatine Treatment on Lipopolysaccharide-Induced Septic Lung Injuries in Rats.

OBJECTIVE: We designed an experimental model of sepsis in rats to investigate the effects of agomelatine (AGO) on lung tissues using molecular and histopathological methods. MATERIALS AND METHODS: In our experimental model, the 32 rats were divided into 4 groups: group 1: control group (HEALTHY); group 2: lipopolysaccharide group (LPS); group 3: LPS plus 50 mg/kg AGO group (LPS + AGO50); and group 4: LPS plus 100 mg/kg AGO group (LPS + AGO100). An LPS-induced sepsis model was performed to replicate the pathology of sepsis. Rats from all 4 groups were killed after 12 hours, and their lungs were quickly collected. To investigate the therapeutic strategy, we evaluated tumor necrosis factor-alpha (TNF-α) and nuclear factor-kappa B (NF-κB) messenger RNA expressions by real-time polymerase chain reaction using molecular methods and lung tissue damage indicators using histopathological methods. RESULTS: The expressions of TNF-α and NF-κB were reduced in the groups treated with AGO. The histopathology results supported the molecular results. CONCLUSION: In this experimental study, we demonstrated for the first time the positive effects of AGO on LPS-induced sepsis in lung tissue using molecular and histopathological methods, indicating that it contributes to the prevention of lung damage.

[A rare complication of port catheter]. / Nadir görülen port kateter komplikasyonu.

Central venous ports are used in long term therapies of cancer patients. The insertion technique and maintenance of central venous ports is very important to avoid catheter associated complications. Widely used central venous ports in cancer patients should be periodically maintained and evaluated by expert physicians. The most frequent complications of central venous ports are catheter obstruction, infection, venous thrombosis and extravasation. In this paper, a rare intrapulmonary catheter dislocation is presented.
