Abstract
BACKGROUND Barley (H. vulgare L.) is an important cereal crop cultivated across various climates globally. Barley and its ancestor (H. vulgare subsp. spontaneum) are an economically valuable model for genetic research and improvement. Drought, among various abiotic stresses, is a substantial threat to agriculture due to its unpredictable nature and significant impact on crop yield. RESULTS This study was conducted in both greenhouse and laboratory settings. Prior to the study, wild barley accessions were pre-selected based on their sensitivity or tolerance to drought as determined from fieldwork in the 2020-2021 and 2021-2022 cropping seasons. The effects of three levels of drought stress were evaluated (control, 90-95% field capacity [FC]; mild stress, 50-55% FC; and severe stress, 25-30% FC). Several parameters were assessed, including seedling and root growth, enzymatic activity (CAT, SOD, POD), soluble protein levels, chlorophyll content, carotenoids, abaxial and adaxial stomatal density and dimensions, and relative gene expression of Dhn1, SOD, POD, and CAT. Drought stress significantly increased enzyme activities, especially at 25-30% FC, and more in the tolerant genotype. On the other hand, sensitive genotypes showed a notable increase in stomatal density. Under drought stress, there was a general decline in seedling and root growth, protein content, chlorophyll and carotenoids, and stomatal dimensions. Importantly, gene expression analysis revealed that Dhn1, SOD, POD, and CAT were upregulated under drought, with the highest expression levels observed in the drought-tolerant genotype under severe stress conditions (25-30% FC). CONCLUSIONS Our investigation highlights the distinct morphological, physiological, biochemical, and gene-expression profiles of drought-resistant and drought-sensitive wild barley genotypes under varying degrees of drought.

Abstract
To enhance crop yield and quality, plant cultivation in controlled-growing systems is an alternative to traditional open-field farming. The use of light-emitting diode (LED) as an adjustable light source represents a promising approach to improve plant growth, metabolism, and function. The objective of this study was to assess the impact of different light spectra (red, red/blue (3:1), blue, and white) with an emission peak of around 656, 656, 450, and 449 nm, respectively, under various replacement methods of nutrient solution (complete replacement (CR), EC-based replacement (ECBR), and replacing based on plant needs (RBPN)), on biomass, physiological traits, and macro- and micronutrient contents of two best-known lettuce varieties, Lollo Rossa (LR) and Lollo Bionda (LB), in the nutrient film technique (NFT) hydroponic system. The results indicated that mix of red and blue LED spectra under RBPN method is the most effective treatment to enhance fresh and dry weights of lettuce plants. In addition, red LED spectrum under RBPN, and red and blue light under ECBR nutrient solution significantly increased leaf stomatal conductance, net photosynthesis and transpiration rate, and intercellular CO2 concentration of LR variety. Phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mn) content in LR variety, and iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn) content in both varieties increased upon exposure to blue and red LED light spectrum with RBPN method. Our results suggest that exposure to combination of red and blue light along with feeding plants using RBPN and ECBR methods can increase absorption of macro- and micronutrient elements and improve photosynthetic properties, and eventually increase lettuce yield with lower nitrate accumulation.

Abstract
The role of bees in the environment, economic, biodiversity and pharmaceutical industries is due to its social behavior, which is oriented from the brain and hypopharyngeal gland that is the center of royal jelly (RJ) production. Limited studies have been performed on the head gene expression profile at the RJ production stage. The aim of this study was to compare the gene expressions in 9 and 1-day-old (DO) honeybee workers in order to achieve better understanding about head gene expression pattern. After sequencing of RNAs, transcriptome and their networks were compared. The head expression profile undergoes various changes. 1662 gene transcripts had differential expressions which 1125 and 537 were up and down regulated, respectively, in 9_DO compared with 1_DO honey bees. The day 1th had more significant role in the expression of genes related to RJ production as major RJ protein 1, 2, 3, 5, 6 and 9 encoding genes, but their maximum secretion occurred at day 9th. All process related to hypopharyngeal glands activities as CYP450 gene, fatty acid synthase gene, vitamin B6 metabolism and some of genes involved in fatty acid elongation and degradation process had an upward trend from 1_DO and were age-dependent. By increasing the age, the activity of pathways related to immune system increased for keeping the health of bees against the chemical compound. The expression of aromatic amino acid genes involved in Phenylalanine, tyrosine and tryptophan biosynthesis pathway are essential for early stage of life. In 9_DO honeybees, the energy supplying, reducing stress, protein production and export pathways have a crucial role for support the body development and the social duties. It can be stated that the activity of honeybee head is focused on energy supply instead of storage, while actively trying to improve the level of cell dynamics for increasing the immunity and reducing stress. Results of current study identified key genes of certain behaviors of honeybee workers. Deeper considering of some pathways will be evaluated in future studies.

Abstract
Osmotic stress can occur due to some stresses such as salinity and drought, threatening plant survival. To investigate the mechanism governing the pistachio response to this stress, the biochemical alterations and protein profile of PEG-treated plants was monitored. Also, we selected two differentially abundant proteins to validate via Real-Time PCR. Biochemical results displayed that in treated plants, proline and phenolic content was elevated, photosynthetic pigments except carotenoid decreased and MDA concentration were not altered. Our findings identified a number of proteins using 2DE-MS, involved in mitigating osmotic stress in pistachio. A total of 180 protein spots were identified, of which 25 spots were altered in response to osmotic stress. Four spots that had photosynthetic activities were down-regulated, and the remaining spots were up-regulated. The biological functional analysis of protein spots exhibited that most of them are associated with the photosynthesis and metabolism (36%) followed by stress response (24%). Results of Real-Time PCR indicated that two of the representative genes illustrated a positive correlation among transcript level and protein expression and had a similar trend in regulation of gene and protein. Osmotic stress set changes in the proteins associated with photosynthesis and stress tolerance, proteins associated with the cell wall, changes in the expression of proteins involved in DNA and RNA processing occur. Findings of this research will introduce possible proteins and pathways that contribute to osmotic stress and can be considered for improving osmotic tolerance in pistachio.

Abstract
Metabolite contents of transgenic sugar beets, S3 and S6, resistant to rhizomania through RNA silencing mechanism, were compared to wild type plant as a part of a risk assessment study. The alteration of S6 transgenic sugar beet metabolites was low and probably due to micro-environmental or natural individual differences. The alteration of S3 transgenic sugar beet metabolites were significant but still within the natural range and, also, beneficial because of high contents of some amino acids, especially essential ones.
Sugar beet is vulnerable to rhizomania as the most destructive viral disease. Two selected events of transgenic sugar beet carrying cassettes inducing RNA silencing mechanism, 219-T3:S3-13.2 (S3) and 6018-T3:S6-44 (S6), were shown to inhibit propagation of Beet Necrotic Yellow Vein Virus, the causative agent. As a method for signifying the substantial equivalence, we analyzed the levels of some metabolites through LC-MS in order to demonstrate possible unintended changes in the leaves of the transgenic events. There was no significant difference in the concentrations of examined key metabolites but cis-aconitate and fructose-1,6-bisphosphatase which were decreased in S3. Also, ATP was reduced in both genetically modified sugar beets. Among free amino acids, only glycine level in S6 was increased compared to the wild plant, while the production levels of 5 and 12 ones were increased in S3 compared to S6 event and the wild type plants, respectively.

Abstract
Within-host models of COVID-19 infection dynamics enable the merits of different forms of antiviral therapy to be assessed in individual patients. A stochastic agent-based model of COVID-19 intracellular dynamics is introduced here, that incorporates essential steps of the viral life cycle targeted by treatment options. Integration of model predictions with an intercellular ODE model of within-host infection dynamics, fitted to patient data, generates a generic profile of disease progression in patients that have recovered in the absence of treatment. This is contrasted with the profiles obtained after variation of model parameters pertinent to the immune response, such as effector cell and antibody proliferation rates, mimicking disease progression in immunocompromised patients. These profiles are then compared with disease progression in the presence of antiviral and convalescent plasma therapy against COVID-19 infections. The model reveals that using both therapies in combination can be very effective in reducing the length of infection, but these synergistic effects decline with a delayed treatment start. Conversely, early treatment with either therapy alone can actually increase the duration of infection, with infectious virions still present after the decline of other markers of infection. This suggests that usage of these treatments should remain carefully controlled in a clinical environment.

Abstract
Rhizomania is an economically important disease of sugar beet, which is caused by Beet necrotic yellow vein virus (BNYVV). As previously shown, RNA silencing mechanism effectively inhibit the viral propagation in transgenic sugar beet plants. To investigate possible proteomic changes induced by gene insertion and/or RNA silencing mechanism, the root protein profiles of wild type sugar beet genotype 9597, as a control, and transgenic events named 6018-T3:S6-44 (S6) and 219-T3:S3-13.2 (S3) were compared by two-dimensional gel electrophoresis. The accumulation levels of 25 and 24 proteins were differentially regulated in S3 and S6 plants, respectively. The accumulation of 15 spots were increased or decreased more than 2-fold. Additionally, 10 spots repressed or induced in both, while seven spots showed variable results in two events. All the differentially expressed spots were analyzed by MALDI-TOF-TOF mass spectrometry. The functional analysis of differentially accumulated proteins showed that most of them are related to the metabolism and defense/stress response. None of these recognized proteins were allergens or toxic proteins except for a spot identified as phenylcoumaran benzylic ether reductase, Pyrc5, which was decreased in the genetically modified S6 plant. These data are in favor of substantial equivalence of the transgenic plants in comparison to their related wild type cultivar since the proteomic profile of sugar beet root was not remarkably affected by gene transfer and activation RNA silencing mechanism.

Abstract
BACKGROUND AND PURPOSE Very-long-chain acyl-CoA dehydrogenase deficiency (VLCADD) is a hereditary disorder of mitochondrial long-chain fatty acid oxidation that has variable presentations, including exercise intolerance, cardiomyopathy and liver disease. The aim of this study was to describe the clinical and genetic manifestations of six patients with adult-onset VLCADD. METHODS In this study, the clinical, pathological and genetic findings of six adult patients (four from Iran and two from Serbia) with VLCADD and their response to treatment are described. RESULTS The median (range) age of patients at first visit was 31 (27-38) years, and the median (range) age of onset was 26.5 (19-33) years. Parental consanguinity was present for four patients. Four patients had a history of rhabdomyolysis, and the recorded CK level ranged between 67 and 90 000 IU/l. Three patients had a history of exertional myalgia, and one patient had a non-fluctuating weakness. Through next-generation sequencing analysis, we identified six cases with variants in the ACADVL gene and a confirmed diagnosis of VLCADD. Of the total six variants identified, five were missense, and one was a novel frameshift mutation identified in two unrelated individuals. Two variants were novel, and three were previously reported. We treated the patients with a combination of L-carnitine, Coenzyme Q10 and riboflavin. Three patients responded favorably to the treatment. CONCLUSION Adult-onset VLCADD is a rare entity with various presentations. Patients may respond favorably to a cocktail of L-carnitine, Coenzyme Q10, and riboflavin.

Abstract
Opium sale is prohibited in Iran, and sellers mix it with lead to increase the weight. Herein, we describe neuromuscular findings in nine patients who developed lead poisoning due to opium/drug consumption. The mean age of patients was 53±3.5 years and their mean blood lead level was 122.6±20.8μg/dL. Most of the patients had an acute/subacute course presenting as axonal or demyelinating sensorimotor polyneuropathy, motor neuron disease, and multiple mononeuropathies with favorable response to the chelation therapy. Lead poisoning should be considered in patients with a history of opium use and neuromuscular symptoms.

Abstract
The results from the first survey on food safety knowledge, attitudes and hygiene practices (KAP) among veterinary medicine students in Bulgaria are reported in this study. It was designed and conducted from September to December 2015 using structured questionnaires on food safety knowledge, attitudes and practices. Data were collected from 100 undergraduate veterinary medicine students from the Trakia University, Bulgaria. It was observed that the age and the gender did not affect food safety knowledge, attitudes and practices. There was no significant difference (p>0.05) on food safety knowledge and practices among students based on the years of study. A high level of food safety knowledge was observed among the participants (85.06%), however, the practice of food safety was above average (65.28%) while attitude toward food safety was high (70%). Although there was a significant awareness of food safety knowledge among respondents, there is a need for improvement on food safety practices, interventions on food safety and foodborne diseases.

Abstract
Diabetes is the most common endocrine disorder in humans with multiple complications including nervous system damages. The aim of the present study was to determine the effect of ginger extract on apoptosis of the neurons of hippocampus, via evaluation of BAX and Cyclin D1 and also histological analysis, in male diabetic rats. In this experimental study, 60 Wistar rats (220 ± 30gr) were conducted in 5 groups as follow: diabetic group treated with saline (group 1), normal group treated with saline (group 2), diabetic group treated with ginger (group 3), diabetic group treated with ginger-insulin (group 4), diabetic group treated with insulin (group 5). STZ (60 mg/kg) was intraperitoneally used to induce the diabetes. Expression levels of BAX and Cyclin D1 were examined using Real-Time PCR technique and the normality of neurons was evaluated using H&E staining method. The results showed that blood glucose level significantly decreased in group 4 when compared to group 1. In molecular analysis, there was no significant difference between groups regarding the expression of BAX gens, while, the expression of Cyclin D1 were significantly decreased in group 4 compared with group 1. Histological analysis revealed that pathological symptoms were lower in group 4 than the other diabetic groups. The results of present study showed that the ginger in addition to lowering blood sugar level, changes the expression of Cyclin D1 gene and histological characteristics in a positive manner. This means that the ginger may protects neurons of the hippocampus from apoptosis in diabetic patients.

Abstract
Facioscapulohumeral muscular dystrophy (FSHD), an inherited and progressive muscle disorder, is among the most common hereditary muscle disorders. From a clinical vantage point, FSHD is characterized by weakness of the facial, shoulder (often with scapular winging), arm (including biceps and triceps) and abdominal muscles. Forearm muscles are usually spared and weakness is usually asymmetrical. Over the past few decades, muscle magnetic resonance imaging (MRI) has become established as a reliable and accurate noninvasive tool for the diagnosis and assessment of progression in neuromuscular diseases, showing specific patterns of muscle involvement for a number of myopathies. More recently, MRI has been used to noninvasively identify quantitative biomarkers, allowing evaluation of the natural progression of disease and assessment of therapeutic interventions. In the present review, the intention was to present the most significant MRI developments related to diagnosis and pattern recognition in FSHD and to discuss its capacity to provide outcome measures.

Abstract
The objective of this study was to develop and compare techniques for determining nutrient flow based on digesta samples collected from the reticulum or rumen of lactating dairy cows with estimates generated by the omasal sampling technique. Pre-experimental method development suggested, after comparing with the particle size distribution of feces, application of primary sieving of ruminal and reticular digesta from lactating cows through an 11.6-mm sieve, implying that digesta particles smaller than this were eligible to flow out of the rumen. For flow measurements at the different sampling sites 4 multiparous, lactating Nordic Red cows fitted with ruminal cannulas were used in a Latin square design with 4 dietary treatments, in which crimped barley was replaced with 3 incremental levels of protein supplementation of canola meal. Digesta was collected from the rumen, reticulum, and omasum to represent a 24-h feeding cycle. Nutrient flow was calculated using the reconstitution system based on Cr, Yb, and indigestible neutral detergent fiber and using (15)N as microbial marker. Large and small particles and the fluid phase were recovered from digesta collected at all sampling sites. Bacterial samples were isolated from the digesta collected from the omasum. Several differences existed for digesta composition, nutrient flows, and estimates of ruminal digestibility among the 3 different sampling sites. Sampling site × diet interactions were not significant. The estimated flows of DM, potentially digestible neutral detergent fiber, nonammonia N, and microbial N were significantly different between all sampling sites. However, the difference between DM flow based on sampling from the reticulum and the omasum was small (0.13kg/d greater in the omasum). The equality between the reticulum and the omasum as sampling sites was supported by the following regression: omasal DM flow=0.37 (±0.649) + 0.94 (±0.054) reticular DM flow (R(2)=0.96 and root mean square error=0.438kg/d). More deviating nutrient-flow estimates when sampling digesta from the rumen than the reticulum compared with the omasum suggested that sampling from the reticulum is the most promising alternative to the omasal sampling technique. To definitively promote sampling from the reticulum as an alternative to the omasal sampling technique, more research is needed to determine selection criteria of reticular digesta for accurate and precise flow estimates across a range of diets.

Abstract
The objective of the present study was to evaluate the effect of different levels of ground oak acorn on growth performance, blood parameters and carcass characteristics. Twenty-four goat kids averaging 16.93 ± 1.25 kg initial bodyweight were randomly assigned to four experimental diets in a completely randomised design for 90 days. The experimental diets consisted of (1) 0% oak acorn (control), (2) 8% oak acorn, (3) 17% oak acorn and (4) 25% oak acorn on a DM basis. The goats were slaughtered after 105 days of feeding and carcass characteristics were measured. DM intake increased linearly in small amounts as the level of acorn in the diet increased (P < 0.004). The results showed that average daily gain, water intake and feed conversion ratio were unaffected by levels of ground oak acorn (P > 0.05). There were no significant differences in blood parameters (P > 0.05). Carcass fat depth and abdominal fat weight decreased with increasing ground oak acorn in the diet. Other carcass characteristics were not affected by different levels of ground oak acorn. On the basis of the results of the present study, it may be concluded that ground oak acorn can be used up to 25% in the diets of young goats without any adverse effects on growth performance and carcass characteristics. At this level of acorns, the goats received low concentrations of hydrolysable tannins (11 g/kg DM) in their diet.

Abstract
Success in breeding crops for yield and other quantitative traits depends on the use of methods to evaluate genotypes accurately under field conditions. Although many screening criteria have been suggested to distinguish between genotypes for their salt tolerance under controlled environmental conditions, there is a need to test these criteria in the field. In this study, the salt tolerance, ion concentrations, and accumulation of compatible solutes of genotypes of barley with a range of putative salt tolerance were investigated using three growing conditions (hydroponics, soil in pots, and natural saline field). Initially, 60 genotypes of barley were screened for their salt tolerance and uptake of Na(+), Cl(-), and K(+) at 150 mM NaCl and, based on this, a subset of 15 genotypes was selected for testing in pots and in the field. Expression of salt tolerance in saline solution culture was not a reliable indicator of the differences in salt tolerance between barley plants that were evident in saline soil-based comparisons. Significant correlations were observed in the rankings of genotypes on the basis of their grain yield production at a moderately saline field site and their relative shoot growth in pots at EC(e) 7.2 [Spearman's rank correlation (rs)=0.79] and EC(e) 15.3 (rs=0.82) and the crucial parameter of leaf Na(+) (rs=0.72) and Cl(-) (rs=0.82) concentrations at EC(e) 7.2 dS m(-1). This work has established screening procedures that correlated well with grain yield at sites with moderate levels of soil salinity. This study also showed that both salt exclusion and osmotic tolerance are involved in salt tolerance and that the relative importance of these traits may differ with the severity of the salt stress. In soil, ion exclusion tended to be more important at low to moderate levels of stress but osmotic stress became more important at higher stress levels. Salt exclusion coupled with a synthesis of organic solutes were shown to be important components of salt tolerance in the tolerant genotypes and further field tests of these plants under stress conditions will help to verify their potential utility in crop-improvement programmes.

Abstract
BACKGROUND Plasma ceruloplasmin (Cp) has been shown to be a risk factor for cardiovascular disease and also to be associated with obesity. However, it is not known whether weight loss could decrease the plasma Cp levels. AIM To investigate the effect of diet-induced weight loss on plasma Cp in obese women. SUBJECTS AND METHODS Sixty-seven healthy obese women [age =33.4±8.7 yr, body mass index (BMI) =36.0±4.8 kg/m2] were entered into a medically supervised program aimed at reducing body weight by 10% or more. Weight loss was achieved through a diet providing a daily energy deficit of 500-1000 kcal/day. In addition, all patients were prescribed to use 50 g of a fiber supplement per day. For all subjects, assessment of dietary intake, anthropometric indices, and plasma levels of C-reactive protein and Cp was performed at the first visit and repeated at 12th week of follow-up. RESULTS By completing the program, weight (Δ=-9.5%, p<0.0001), BMI (Δ=-9.7%, p<0.0001), waist-circumference (Δ=-6.1%, p<0.0001), and triceps skinfold thickness (Δ=-14.9%, p<0.0001) significantly decreased. Plasma Cp significantly decreased after 12 weeks of dietary intervention (33.6±5.6 mg/dl vs 25.2±5.8 mg/dl, p<0.0001). Percent change in Cp was correlated with percent change in waist-circumference (r=446, p=0.015). CONCLUSION Our study suggests that an improved body composition induced by restriction of energy intake is associated with decreased serum concentrations of Cp in obese women which in turn might have reduced the subjects' risk of developing cardiovascular disease.

Abstract
BACKGROUND Dental pulp stones are discrete calcifications in the pulp chamber which are often seen in deciduous and permanent teeth. It has been hypothesised that atherosclerosis can be associated with their development. OBJECTIVE To determine whether a higher prevalence of dental pulp stones is correlated with coronary artery stenosis. CLINICAL SETTING Sixty-one patients aged 20-55 years referred to Afshar Heart Center for invasive coronary angiography were invited to undergo panoramic dental radiography. The panoramic radiographs were independently examined for the presence of pulp stones. RESULTS Pulp stones were present in 82% (31/38) of patients with at least one clinically significant coronary artery stenosis and in 48% (11/23) of patients with normal coronary angiography. They were present in 13% of the teeth in the former group and in 5% of the teeth in the latter. The findings show a statistically significant association between coronary artery stenosis and presence of pulp stones (odds ratio 4.83, 95% confidence interval 1.5-15.4). CONCLUSION Coronary artery stenosis and dental pulp calcification are significantly associated. Dental radiography has the potential to be used as a rapid screening method for the early detection of coronary artery stenosis.

Abstract
Soil salinity affects large areas of the world's cultivated land, causing significant reductions in crop yield. Despite the fact that most plants accumulate both sodium (Na(+)) and chloride (Cl(-)) ions in high concentrations in their shoot tissues when grown in saline soils, most research on salt tolerance in annual plants has focused on the toxic effects of Na(+) accumulation. It has previously been suggested that Cl(-) toxicity may also be an important cause of growth reduction in barley plants. Here, the extent to which specific ion toxicities of Na(+) and Cl(-) reduce the growth of barley grown in saline soils is shown under varying salinity treatments using four barley genotypes differing in their salt tolerance in solution and soil-based systems. High Na(+), Cl(-), and NaCl separately reduced the growth of barley, however, the reductions in growth and photosynthesis were greatest under NaCl stress and were mainly additive of the effects of Na(+) and Cl(-) stress. The results demonstrated that Na(+) and Cl(-) exclusion among barley genotypes are independent mechanisms and different genotypes expressed different combinations of the two mechanisms. High concentrations of Na(+) reduced K(+) and Ca(2+) uptake and reduced photosynthesis mainly by reducing stomatal conductance. By comparison, high Cl(-) concentration reduced photosynthetic capacity due to non-stomatal effects: there was chlorophyll degradation, and a reduction in the actual quantum yield of PSII electron transport which was associated with both photochemical quenching and the efficiency of excitation energy capture. The results also showed that there are fundamental differences in salinity responses between soil and solution culture, and that the importance of the different mechanisms of salt damage varies according to the system under which the plants were grown.

Abstract
BACKGROUND Exercise can change the release of numerous cytokines and modulate their receptor systems. Dietary ω-3 lipids may decrease the levels of inflammatory cytokines and prostaglandins (PGs). Therefore, in this study, we investigated the effects of exercise and eicosapentaenoic acid (EPA) supplementation, with or without vitamin E, on the blood levels of IL-2, TNF-α, catalase, glutathione reductase, and MDA in male basketball players. METHODS Thirty-four well-trained male basketball players were enrolled into the study. Venous blood samples were obtained from all subjects between 5:00 and 6:00 p.m., after intensive endurance exercising for 2 hours, at the baseline and after intervention. Subjects received 2g EPA and/or 400 IU vitamin E or placebo depends on their groups for 6 weeks. RESULTS There were significant fall (paired t-test) in TNF-α in group1(P< 0.05), and in MDA in group 3 (P<0.05), whereas there were significant increase in glutathione reductase in groups1 and 3 (P< 0.05), and in MDA in group2 (P< 0.05).There were significant differences (Tukey) in glutathione reductase between groups 2 and 3 (P< 0.05), and in IL-2 between groups 1 and other groups (P< 0.01), but there were no significant differences in MDA, CAT, and TNF-α, among groups after 6 week of intervention. CONCLUSION Six weeks of EPA+vitamin E supplementation enhances the plasma levels of IL-2 and erythrocytes glutathione reductase, whereas it reduces TNF-α, and 6 weeks of EPA supplementation alone enhances only the serum level of MDA.

Abstract
Introduction Co-occurrence of multiple sclerosis (MS) and neurofibromatosis type 1 (NF1) is rare. Case reports In this study, we describe the clinical and neuroimaging features of seven patients with NF1 and MS. In our patients, six patients with MS were women, in all of them history of NF1 existed. Three of our patients had primary progressive, one had secondary progressive MS, and three relapsing–remitting MS. Optic neuritis as presenting symptoms was seen in three patients, and motor manifestation as presenting symptom was observed in three patients. The risk of having both NF1 and MS seemed to be higher than would be expected based on the prevalence rates of the two diseases in the general population. Conclusion The findings of this study suggest a possible casual relationship between MS and NF1, indicating higher risk of MS among patients with NF1.

Abstract
In the present work, adenosine agonists and antagonists on apomorphine-induced yawning in rats was investigated. Subcutaneous (SC) injection of apomorphine (0.02, 0.05 and 0.1 mg/kg) induced dose-dependent yawning behaviour in rats. Intracerebroventricular (ICV) administration of different doses of the drug (1, 3, 5 micrograms/rat) also caused a dose-related yawning. ICV administration of the adenosine receptor agonists 5-N-ethylcarboxamidoadenosine (NECA) and N6-cyclohexyladenosine (CHA) decreased apomorphine-induced yawning. The response induced by the adenosine agonists was reduced by 8-phenyladenosine (8-PT) pretreatment. The yawning induced by SC and ICV administration of apomorphine was decreased by ICV or IP injection of theophylline, respectively. It is concluded that at least A1 adenosine receptors may exert negative influence on the apomorphine-induced yawning. However, the exact mechanism(s) of adenosine receptors in this behaviour remain to be established.
