Abstract
BACKGROUND To investigate the genetics of early-onset progressive cerebellar ataxia in Iran, we conducted a study at the Children's Medical Center (CMC), the primary referral center for pediatric disorders in the country, over a three-year period from 2019 to 2022. In this report, we provide the initial findings from the national registry. METHODS We selected all early-onset patients with an autosomal recessive mode of inheritance to assess their phenotype, paraclinical tests, and genotypes. The clinical data encompassed clinical features, the Scale for the Assessment and Rating of Ataxia (SARA) scores, Magnetic Resonance Imaging (MRI) results, Electrodiagnostic exams (EDX), and biomarker features. Our genetic investigations included single-gene testing, Whole Exome Sequencing (WES), and Whole Genome Sequencing (WGS). RESULTS Our study enrolled 162 patients from various geographic regions of our country. Among our subpopulations, we identified known and novel pathogenic variants in 42 genes in 97 families. The overall genetic diagnostic rate was 59.9%. Notably, we observed PLA2G6, ATM, SACS, and SCA variants in 19, 14, 12, and 10 families, respectively. Remarkably, more than 59% of the cases were attributed to pathogenic variants in these genes. CONCLUSIONS Iran, being at the crossroad of the Middle East, exhibits a highly diverse genetic etiology for autosomal recessive hereditary ataxia. In light of this heterogeneity, the development of preventive strategies and targeted molecular therapeutics becomes crucial. A national guideline for the diagnosis and management of patients with these conditions could significantly aid in advancing healthcare approaches and improving patient outcomes.

Abstract
Objectives Therapeutic plasma exchange (TPE) is a plasmapheresis procedure whose Safety data for pediatric neuro-immunological disorders (PNID) is confined. The present research documents TPE's safety and feasibility data in these conditions. Materials & Methods The current study involved six distinct groups of patients with PNID undergoing TPE: neuromyelitis optic spectrum disorder (NMOSD), autoimmune encephalitis (AIE), acute disseminated encephalomyelitis (ADEM), multiple sclerosis (MS), Guillain-Barre syndrome (GBS), and optic neuritis (ON). This study documented complications related to each TPE process. In addition, TPE's efficacy was studied in these patients. Results The present study recorded adverse effects in 18 patients with PNID that received 121 TPE cycles: five cycles (4.13%) in MS, three (2.48%) in AIE subgroup, one (0.82%) in ADEM, and two (1.65%) in GBS. No severe complications were observed among the patients. Conclusion Patients with PNID tolerated therapeutic plasma exchange, which was a safe process.

Abstract
OBJECTIVES In Ireland, regularly reviewed Individual Care Plans (ICPs) for inpatients at all acute psychiatric inpatient units are a requirement of the Mental Health Act . In this study, we comprehensively evaluated and compared opinions of key stakeholders in relation to the ICP as a care delivery tool. METHODS We employed a descriptive survey design. Questionnaires were distributed to 123 stakeholders (patients and mental health professionals (MHPs)) to evaluate and compare opinions regarding the impact of the ICP in relation to healthcare delivery and health outcomes, and regarding the structure and frequency of use of the ICP. RESULTS Ninety-eight stakeholders (80%) completed study questionnaires. Stakeholders (patients (58%) and MHPs (85%)) reported that the ICP assisted in healthcare delivery. However, different attitudes between groups were noted in relation to whether the ICP contributed towards healthcare outcomes, with 64% of patients, but only 41% of MHPs reporting that the ICP positively contributed to mental healthcare outcomes. Some free-text comments described patient dissatisfaction with the role of the ICP for healthcare delivery, and MHP dissatisfaction that the ICP was time-consuming and did not significantly enhance standard patient care. CONCLUSION Whilst the implementation of the ICP is generally viewed positively by both patients and MHPs, considerable dissatisfaction by MHPs was also noted with certain aspects of how the ICP was delivered in practice. Practical adjustments to the implementation of ICP in order to build more positive stakeholder experiences appear warranted and worthy of further research.

Abstract
BACKGROUND Breath-holding spells (BHS) are common in infancy and early childhood and may appear like seizures. Factors such as autonomic dysfunction and iron deficiency anemia are thought to contribute to the incidence of BHS. In this study, electrocardiographic (ECG) parameters of patients with BHS were compared to those of healthy, normal children. Logistic regression and machine-learning (ML) models were then created to predict these spells based on ECG characteristics. METHODS In this case-control study, 52 BHS children have included as the case and 150 healthy children as the control group. ECG was taken from all children along with clinical examinations. Multivariate logistic regression model was used to predict BHS occurrence based on ECG parameters. ML model was trained and validated using the Gradient-Boosting algorithm, in the R programming language. RESULTS In BHS and control groups, the average age was 11.90 ± 6.63 and 11.33 ± 6.17 months, respectively (p = .58). Mean heart rate, PR interval, and QRS interval on ECGs did not differ significantly between the two groups. BHS patients had significantly higher QTc, QTd, TpTe, and TpTe/QT (all p-values < .001). Evaluation of the ML model for prediction of BHS, fitting on the testing data showed AUC, specificity, and sensitivity of 0.94, 0.90, and 0.94 respectively. CONCLUSION There are repolarization changes in patients with BHS, as the QTc, QTd, TpTe, and TpTe/QT ratio were significantly higher in these patients, which might be noticeable for future arrhythmia occurrence. In this regard, we developed a successful ML model to predict the possibility of BHS in suspected subjects.

Abstract
This study was conducted to compare nutrient digestibility, performance and immune response of dairy cows received live and autolyzed yeast during the transition period in high ambient temperature. Cows (n = 25) were randomly divided and received a basal diet with or without live yeast or autolyzed yeast as on top three weeks pre-parturition until three weeks post-parturition. The Control group received a basal diet without yeast products; other groups received 0.5 g live yeast; 1.0 g live yeast; 10 g autolyzed yeast and 20 g/d/head autolyzed yeast. Live yeast resulted in higher nutrient digestibility compared with autolyzed yeast and the control. Methane production was the highest in autolyzed yeast and the lowest in live yeast. Average milk production was the highest in cows that received live yeast. The highest IgG level was for cows that received autolyzed yeast at a dose of 20 g/d/head. Live yeast had no significant effect, but autolyzed yeast increased the relative expression of γ-Interferon and interleukin-2 as compared with the control group. It was concluded that live yeast at a dose of 1.0 g/d/head could influence ruminal fermentation and milk production, but autolyzed yeast at a dose of 20 g/d/head could influence the immune response of dairy cows during the transition period and heat stress.

Abstract
Leukodystrophies (LDs) are a heterogeneous group of progressive neurological disorders and characterized by primary involvement of white matter of the central nervous system (CNS). This is the first report of the Iranian LD Registry database to describe the clinical, radiological, and genomic data of Persian patients with leukodystrophies. From 2016 to 2019, patients suspicious of LDs were examined followed by a brain magnetic resonance imaging (MRI). A single gene testing or whole-exome sequencing (WES) was used depending on the neuroradiologic phenotypes. In a few cases, the diagnosis was made by metabolic studies. Based on the MRI pattern, diagnosed patients were divided into cohorts A (hypomyelinating LDs) versus cohort B (Other LDs). The most recent LD classification was utilized for classification of diagnosed patients. For novel variants, in silico analyses were performed to verify their pathogenicity. Out of 680 registered patients, 342 completed the diagnostic evaluations. In total, 245 patients met a diagnosis which in turn 24.5% were categorized in cohort A and the remaining in cohort B. Genetic tests revealed causal variants in 228 patients consisting of 213 variants in 110 genes with 78 novel variants. WES and single gene testing identified a causal variant in 65.5% and 34.5% cases, respectively. The total diagnostic rate of WES was 60.7%. Lysosomal disorders (27.3%; GM2-gangliosidosis-9.8%, MLD-6.1%, KD-4.5%), amino and organic acid disorders (17.15%; Canavan disease-4.5%, L-2-HGA-3.6%), mitochondrial leukodystrophies (12.6%), ion and water homeostasis disorders (7.3%; MLC-4.5%), peroxisomal disorders (6.5%; X-ALD-3.6%), and myelin protein disorders (3.6%; PMLD-3.6%) were the most commonly diagnosed disorders. Thirty-seven percent of cases had a pathogenic variant in nine genes (ARSA, HEXA, ASPA, MLC1, GALC, GJC2, ABCD1, L2HGDH, GCDH). This study highlights the most common types as well as the genetic heterogeneity of LDs in Iranian children.

Abstract
Objectives The SARS-CoV-2 pandemic is the most challenging crisis in the contemporary world. Besides severe pulmonary involvement, the disease also has several extrapulmonary manifestations, and new signs and symptoms are associated with it every dayThe present study aimed to inquire about the frequency of neurological manifestations and risk factors of COVID-19. Materials & Methods This retrospective, descriptive study included patients with neurological involvement admitted to the Alborz University of Medical Sciences academic hospitals from March 2020 to July 2020 with confirmed COVID-19 infection. The data included in the analysis were the patient's demographic information, underlying diseases, neurological manifestations, and laboratory findings. Results The study included ninety-five patients with a mean age of fifty-nine. Neurological symptoms and signs were observed in 91.6% and 10.5% of the patients, respectively. The most frequently associated neurological symptoms of COVID-19 were fatigue (49.5%), headache (47.4%), and dizziness (45.3%). Furthermore, the most common neurological involvements included gait disorders (6.3%), cerebellar dysfunction (4.2%), and cerebrovascular accidents (3.15%). Positive troponin was shown to be the strongest predictor of neurological signs (OR=21, P=0.017), followed by WBC≥15,000 (OR = 20.75, P=0.018) and a history of respiratory disease (OR=7.42, P=0.007). Conclusion Neurological symptoms were observed in more than 91% of the patients, while neurological signs were present in 10.5% of the COVID-19 patients. Additionally, positive troponin, WBC≥15,000, and a history of respiratory disease were the strongest predictors of neurological signs.

Abstract
OBJECTIVES Due to a lack of data on pediatric multiple sclerosis (MS) epidemiology in Iran, this study aimed to determine the incidence rate of pediatric MS in Iran. MATERIALS & METHODS All the data of the patients with MS registered in the Ministry of Health and Medical Education of Iran for 20 years were collected in this study; those born in 1982 and diagnosed with the disease and treated since 2000 were included in this study. Therefor The collected variables were patients' age at the time of diagnosis, gender, year of diagnosis, urban or rural residency, and province of residence. Additionally, age-specific incidence rates per 100,000 of the population were calculated. RESULTS This study was performed on 4544 cases of pediatric MS within 2000-2019, of which 997 patients (21.9%) were male. The mean age of the patients with MS at the time of diagnosis was 14.3±4.6 years, and 4414 children (97.1%) lived in urban areas. The incidence rate of pediatric MS in Iran during 20 years increased from 0.26 per 100,000 of the population in 2000 to 1.53 in 2019. CONCLUSION The incidence of pediatric MS in Iran is high, and the development of diagnostic practices in the past decade in Iran has contributed to the detection of this high incidence.

Abstract
A 10-year-old boy who was referred due to acute hydrocephalus symptoms was diagnosed as the first case of pediatric DLGNT in Iran. The results suggested that using shunting for hydrocephaly and anti-seizure medicines, as well as chemotherapeutic agents, can be an effective treatment strategy for DLGNT. Although the patient was stable without a tumor recurrence for a limited follow-up period of 22 months, further studies are expected.

Abstract
Purpose An increasing number of studies have reported a significant association between long non-coding RNAs (lncRNAs) dysregulation and pancreatic cancers. In the present study, we aimed to gather articles to evaluate the prognostic value of long non coding RNA in pancreatic cancer. Experimental design We systematically searched all eligible articles from databases of PubMed, Web of Science, and Scopus to meta-analysis of published articles and screen association of multiple lncRNAs expression with clinicopathology and/or survival of pancreatic cancer. The pooled hazard ratios (HRs) and their 95% confidence intervals (95% CIs) were used to analysis of overall survival, disease-free survival and progression-free survival were measured with a fixed or random effects model. Results A total of 39 articles were included in the present meta-analysis. Our results showed that dysregulation of lncRNAs were linked to overall survival (39 studies, 4736 patients HR = 0.41, 95% CI 0.25 ± 0.58, random-effects in pancreatic cancer. Moreover, altered lncRNAs were also contributed to progression-free survival (8 studies, 1180 patients HR: 1.88, 95% CI (1.35–2.62) and disease-free survival (2 studies, 285 patients, HR: 6.07, 95% CI 1.28–28.78). In addition, our findings revealed the association between dysregulated RNAs and clinicopathological features in this type of cancer. Conclusions In conclusion, dysregulated lncRNAs could be served as promising biomarkers for diagnosis and prognosis of pancreatic cancer.

Twenty-four close-up dry cows with a mean of 259 ± 1days of pregnancy and expected 21 ± 1days prior to parturition were selected. The cows were fed four diets: 1) basal diet without selenium supplementation (C); 2) basal diet plus 0.5ppm selenium in the form of sodium selenite (Se-S) 3) basal diet plus 0.5ppm selenium in the form of selenium yeast (Se-Y); 4) basal diet plus 0.5ppm selenium in the form of selenomethionine (Se-M). Blood samples for measuring hematological blood parameters (including lymphocyte, red blood cells, hemoglobin, and hematocrit, MCV, MCH, MCHC and RDWc) were taken at 21 and 10 days before delivery, delivery date, 10 and 21 days after delivery. There was no significant difference in hematological parameters before and after delivery in experimental and control groups. However, in the prepartum period, MCH tended to increase significantly in selenium methionine treatment (p<0.05). Reproductive parameters (including distance to first estrus, insemination indexes and number of open days) and health parameters (including rectum temperature and vaginal content score) have been improved by selenium organic supplements. The results of this experiment showed that feeding organic selenium supplementation in multiparous dairy cow’s diet may improve their health and reproduction.

Abstract
Movement disorders are common neurologic disturbances in childhood. There are two major types of movement disorders. Hypokinetic disorders are with paucity of voluntary movements and are very uncommon in pediatric age group. Hyperkinetic movement abnormalities are very common in children and defined as abnormal repetitive involuntary movements. Movement disorders in childhood and even in adolescents are different in etiology, timing, treatment and prognosis versus adulthood movement abnormalities. In this brief article, we reviewed common types of hyperkinetic abnormal movements in children and adolescents with emphasis on etiologies, new classifications and recent treatment strategies.

Abstract
Kawasaki disease (KD) is an inflammatory vasculitis. KD is classified into two groups based on clinical characteristics criteria, namely classic and incomplete. Cerebral vascular abnormality, especially arterial ischemic stroke (AIS) is very rare and unusual in KD. Here, we report a 4-year-old boy who was referred to our tertiary pediatric center with abrupt right hemiparesis and aphasia. At admission time, he had febrile illness and was toxic. On physical examination, we found unilateral left submandibular lymphadenopathy. On neurologic examination, we obtained right sided hemiparesis with hemiparetic gait and aphasia. His deep tendon reflexes (DTRs) of right extremities were exaggerated and his sensory system was intact. Based on these features, some differential diagnoses were suggested, such as acute encephalitis with focal signs, brain abscess, cerebral vasculitis, hemorrhagic insults, and ischemic stroke, etc. After a complete evaluation, especially brain MRI and MRA, our diagnosis was arterial ischemic stroke (AIS) following atypical KD. Based on these findings, we administered intravenous immunoglobulin (IVIG 2 gm/kg) and oral high dose aspirin (100 mg/kg/d). He responded to these anti-inflammatory treatments dramatically.

Abstract
OBJECTIVE Guillain-Barre Syndrome (GBS) is an acute polyradiculoneuropathy characterized by progressive motor weakness of limbs and areflexia. In this study, our aim was to evaluate the clinical pattern and prognosis of children with Guillain-Barre syndrome. MATERIALS & METHODS This cross-sectional study was conducted in the Pediatric Neurology Unit of Amirkola Children's Hospital, Babol, Iran during the period of 5 years from October 2008 to September 2013. We assessed the clinical features, results of electrodiagnostic tests, functional status, treatment and outcome of 17 children diagnosed with GBS. RESULTS Of 17 (male to female ratio = 1.6:1) children studied, all had motor weakness, 4 children (23.5 %) and cranial nerve palsies. Respiratory paralysis was found in one child requiring assisted ventilation. Antecedent illness preceding GBS was recorded in 7 (41.2%) children. The GBS subtype distribution as per electrodiagnostic studies was as follows: acute inflammatory demyelinating polyradiculoneuropathy (AIDP) in 12 (70.6%) acute motor axonal neuropathy (AMAN) in 3 (17.6%), acute motor sensory axonal neuropathy (AMSAN) in 2 (11.8%). IVIG constituted the treatment given in all of the patients. Complete recovery was observed in 16 children and the remaining one child was dependent to wheelchair. CONCLUSION GBS in children is not poor prognostic disorder and our recommendation is administration of IVIG as soon as possible after clinical diagnosis. Except for one child who remained wheelchair bound, there was no mortality or morbidity in long-term observation. Besides, strong limitation of our study was the low number of subjects.

Abstract
The common diagnosis of loss of consciousness and clonic movements in children is seizure or epilepsy, but in a number of patients these symptoms could also be due to syncope. Over interpreted electroencephalography is misleading in a number of patients; therefore, in addition to a detailed and thorough history, a reliable test is needed to differentiate between these conditions. The aim of the study was to evaluate the utility of the head upright tilt test to differentiate between seizure-like events and syncope in children. A chart review descriptive study was conducted in a tertiary medical center in Ahvaz, Iran. We selected sixteen children (nine boys and seven girls) with convulsions of any type who were first diagnosed as epileptic based on the event description by their parents or caregivers to undergo the head upright tilt test. The main findings were the reproduction of previously presyncopal or syncopal symptoms in the tilted position. Fourteen children showed positive results after conducting the head upright tilt test, and their heart rates were significantly decreased compared to baseline at the onset of the syncopal or presyncopal manifestations. Systolic and diastolic blood pressures were significantly reduced in patients with positive results. In three children who initially had negative head upright tilt tests, intravenous isoproterenol was administered, and all three showed presyncopal and syncopal symptoms. The results indicate that the head upright tilt test could differentiate presyncopal and syncopal events in children who present with seizure-like movements but their history has clues for conclusive syncope.

Abstract
Long-term potentiation (LTP) has been most thoroughly studied in the hippocampus, which has a key role in learning and memory. Endocannabinoids are one of the endogenous systems that modulate this kind of synaptic plasticity. The activation of the vanillioid system has also been shown to mediate synaptic plasticity in the hippocampus. In addition, immunohistochemical studies have shown that cannabinoid receptor type 1 (CB1) and vanilloid receptor 1 (TRPV1) are closely located in the hippocampus. In this study, we examined the hippocampal effects of co-administrating WIN55-212-2 and capsaicin, which are CB1 and TRPV1 agonists, respectively, on the induction of LTP in the dentate gyrus (DG) of rats. LTP in the hippocampal area was induced by high-frequency stimulation (HFS). Our results indicated that the cannabinoid agonist reduced both field excitatory post-synaptic potential (fEPSP) slope and population spike (PS) amplitude after HFS with respect to the control group, whereas the vanilloid agonist increased these parameters along with the increased induction of LTP as compared to the control group. We also showed that the co-administration of cannabinoid and vanilloid agonists had different effects on fEPSP slope and PS amplitude. It seems that agonists of the vanilloid system modulate cannabinoid outputs that cause an increase in synaptic plastisity, while in contemporary consumption of two agonist, TRPV1 agonist can change production of endocannabinoid, which in turn result to enhancement of LTP induction. These findings suggest that the two systems may interact or share certain common signaling pathways in the hippocampus.

Abstract
OBJECTIVE The aim of this study was to evaluate the efficacy and safety of intramuscular midazolam in controlling convulsive status epilepticus in children, by comparing it with rectal diazepam. METHODS In this randomized trial, 100 children (50 in each group) with convulsive status epilepticus aged 1 month to 16 years were enrolled and randomly assigned into two groups to receive either 0.3 mg/kg intramuscular midazolam or 0.5 mg/kg rectal diazepam. Main outcome measure was stopping of all motor activity after drug administration. Another measures were times between patient's arrival to emergency department till drug administration, between drug administration to seizure cessation, and between patient's arrival to seizure cessation. RESULTS Both medication were effective for seizure control and no significant difference was found between successful treatments after administering the medication (P = 0.061). In the midazolam group, in 96% (48/50) of cases treatment was successful and in the diazepam group, in 94% (47/50) of cases treatment was successful. Time from arrival to administering the medication was significantly shorter in midazolam group (P = 0.017). The majority of seizures in midazolam group were stopped in less than 66 s (median) compared to 130 s (median) for diazepam group, (P < 0.001). No serious adverse effects were seen in both groups. CONCLUSION IM midazolam is not superior but may be at least as effective as rectal diazepam for controlling of status epilepticus in children. Midazolam via IM route could be one of the choices in children with convulsive status seizures who have difficult IV access.

Abstract
Alzheimer's disease (AD) begins with impairment in synaptic functions before developing into later neurodegeneration and neural loss. In the present study we have examined the protective effects of Borago Officinalis (borage) extract on amyloid β (Aβ)--Induced long term potentiation (LTP) disruption in hippocampal dentate gyrus (DG). Wistar male rats received intrahippocampal (IHP) injection of the Aβ (25-35) and borage extract throughout gestation (100 mg/kg). LTP in perforant path- DG synapses was assessed using electrophysiology method and field excitatory post- synaptic potential (fEPSP) slope and population spike (PS) amplitude were measured by 400 Hz tetanization. Finally, the total thiol content of hippocampus was measured using colorimetric reaction based on the Ellman's method. The results showed that Aβ (25-35) significantly decreased fEPSP slope and SP amplitude comparing with the control and sham group, whereas borage extract administration increased these parameters compared to the Aβ group. Aβ induced a remarkable decrease in total thiol content of hippocampus and borage prevented the decrease of the hippocampal total sulfhydryl (SH) groups. This data suggest that Aβ (25-35) can effectively inhibit LTP in the granular cells of the DG in hippocampus, and borage supplementation reverse the synaptic plasticity in DG following Aβ treatment and that borage consumption may lead to an improvement of AD-induced cognitive dysfunction.

Abstract
Twelve multiparous Holstein dairy cows were used in a replicated 4 × 4 Latin square changeover design to evaluate the effects of graded inclusion of soya bean hulls (SHs) in replacement of diet forages at 0%, 10%, 20% and 30% of dietary dry matter (DM) basis on peNDF > 8 and peNDF > 1.18 contents of diets and their resulting effects on chewing activity, nutrient digestibility and milk production of dairy cattle. The control diet contained 50% forage, 50% concentrate and no SH. In the other three diets, SH was substituted for alfalfa hay, corn silage and wheat bran to supply 10%, 20% and 30% of the dietary DM. Increasing SH concentration in the diets resulted in decreasing concentrations of forage neutral detergent fibre (NDF), physically effective NDF (peNDF) and mean particle size (p < 0.01). Chewing activity per kilogram of daily dry matter intake (DMI) was not affected by the different diets tested. However, chewing activity significantly decreased for kilogram intake of NDF, but increased for peNDF > 1.18 when SH was included in the diets (p < 0.01). Total tract apparent digestibility of nutrients significantly increased for DM, organic matter (p < 0.05) and NDF (p < 0.01) but decreased for crude protein (p < 0.05) as the proportion of SH was increased in the diets. Rumen pH value of cattle was not influenced by the diets. Including medium and high amounts of SH in the diets decreased DMI of the animals (p < 0.05) without any significant effect on their daily milk or 4% fat-corrected milk production. In conclusion, the results of this study showed that the NDF from a non-forage fibre source like SH had a lower potential for stimulating chewing activity than did forage NDF. Despite this, the small size of dietary particles increased not only the chewing activity per kilogram of peNDF intake but also saliva secretion as well as the potential for rumen to neutralize acids. The findings of this study demonstrate the greater differences in peNDF > 8 among the diets and that these differences are better reflected in terms of DMI, chewing activity and nutrient digestibility, but not in rumen pH.

Abstract
OBJECTIVE Stroke is most important cause of death and disability in adults. The hippocampal CA1 and sub-ventricular zone neurons are vulnerable to ischemia that can impair memory and learning functions. Although neurogenesis normally occurs in the dentate gyrus (DG) of the hippocampus and sub-ventricular zone (SVZ) following brain damage, this response is unable to compensate for severely damaged areas. This study aims to assess both neurogenesis and the neuroprotective effects of transforming growth factor-alpha (TGF-α) on the hippocampus and SVZ following ischemia-reperfusion. MATERIALS AND METHODS In this experimental study, a total of 48 male Wistar rats were divided into the following groups: surgical (n=12), phosphate buffered saline (PBS) treated vehicle shams (n=12), ischemia (n=12) and treatment (n=12) groups. Ischemia was induced by common carotid occlusion for 30 minutes followed by reperfusion, and TGF-α was then injected into the right lateral ventricle. Spatial memory was assessed using Morris water maze (MWM). Nestin and Bcl-2 family protein expressions were studied by immunohistochemistry (IHC) and Western blot methods, respectively. Finally, data were analyzed using Statistical Package for the Social Sciences (SPSS, SPSS Inc., Chicago, USA) version 16 and one-way analysis of variance (ANOVA). RESULTS TGF-α injection significantly increased nestin expression in both the hippocampal DG and SVZ areas. TGF-α treatment caused a significant decrease in Bax expression and an increase in Bcl-2 anti-apoptotic protein expression in the hippocampus. Our results showed a significant increase in the number of pyramidal neurons. Memory also improved significantly following TGF-α treatment. CONCLUSION Our findings proved that TGF-α reduced ischemic injury and played a neuroprotective role in the pathogenesis of ischemic injury.

Abstract
INTRODUCTION Exposure to 3, 4- methylenedioxymethamphetamine (MDMA) could lead to serotonergic system toxicity in the brain. This system is responsible for learning and memory functions. Studies show that MDMA causes memory impairment dose-dependently and acutely. The present study was designed to evaluate the chronic and acute effects of MDMD on spatial memory and acquisition of passive avoidance. METHODS Adult male Wistar rats (200-250 g) were given single or multiple injections of MDMA (10 mg/kg, IP). Using passive avoidance and Morris Water Maze (MWM) tasks, learning and spatial memory functions were assessed. The data were analyzed by SPSS 16 software and one- way analysis of variance (ANOVA) test. RESULTS Our results showed that there were significant differences in latency to enter the dark compartment (STL) between sham and MDMA- treated groups. Acute group significantly showed more STL in comparison with chronic group. Furthermore, MDMA groups spent more time in dark compartment (TDS) than the sham group. Administration of single dose of MDMA significantly caused an increase in TDS compared with the chronic group. In the MWM, MDMA treatment significantly increased the traveled distance and escaped latency compared to the sham group. Like to passive avoidance task, percentage of time spent in the target quadrant in MDMA- treated animals impaired in MWM compared with sham group. DISCUSSION These data suggest that MDMA treatment impairs learning and memory functions that are more extensive in acute- treated rats.

Abstract
The objective was to establish prolonged effects of a rumen-protected Met (RPM) product (SmartamineM) on milk production and reproduction of high-producing early-lactation cows under extended very high ambient temperatures. Twenty four fresh Holstein cows (27 +/- 9 days in milk, 617 kg b.wt., 2.8 body condition score) including 12 second lactation and 12 higher lactation cows were randomly assigned to either control or RPM-supplemented total mixed rations (TMR, 520:480 g kg(-1) forage:concentrate), and were fed continuously for 5 months. Cows were offered TMR 3 times daily post-milking plus a top-dress alfalfa hay. The study was conducted from May through November of 2009 in central Iranian province of Isfahan. The RPM group had consistently greater 5-month-long average DM intake (21.9 vs. 19.1 kg day(-1)), milk yield (42.4 vs. 37.4 kg day(-1)), milk fat content (33 vs. 27.5 g kg(-1)), fat yield (1.40 vs. 1.04 kg day(-1)), milk protein content (29.6 vs. 27.5 g kg(-1)) and protein yield (1.25 vs. 1.02 kg day(-1)). Mature cows tended to produce more milk (42.2 vs. 37.6 kg day(-1)) and milk fat (1.30 vs. 1.13 kg day(-1)) than second lactation cows. The RPM significantly improved ovary function, estrus expression visibility and body condition score (3 vs. 2.6), while shortening days open (106 vs. 143) and calving interval (387 vs. 421 d). Findings provide compelling evidence for beneficial effects of prolonged RPM provision on feed intake, milk production, and reproduction of Holstein cows under concurrent metabolic pressures of early lactation and stressful high ambient temperatures.
