Abstract

Objective: The aim of this study is to assess the knowledge and attitude of pharmaceutical students around self-medication, common medicines and Drug and Poison Information Center (DPIC) for the first time. Methods: This cross-sectional study was carried out on 204 pharmaceutical students. Data were collected using questionnaire including socio-demographic questions, general and specialized information about Drugs, DPIC, and drugs side effects. All analysis conducted using the SPSS 16.0 software. Results: Of the total 204 participants, 93(45.6%) respondents were males and 111(54.4%) of them were females by the mean age of 22.05 (±1.5). More than half of the respondents (52%) had no information about DPIC and its functions. Approximately 44% of students have a consultation with a pharmacist for drug use. Averagely, only 39.88% of students had suitable drugs information. Significant relationship was observed between age and medicine consultation (P = 0.025). Conclusion: This study showed that the pharmaceutical students had a poor knowledge about the prevalence of using different drugs and DPIC’s functions. Country's medical system is still facing the problem of uncontrolled usage and also a lack of knowledge, so it is recommended to perform comprehensive studies for finding factors that effect on students’ awareness to improve their academic performance.

Abstract

N-acetylcysteine (NAC) is a drug used widely and effectively in oral and ‎ intravenous forms as a specific antidote for acetaminophen poisoning. In children ‎ considering the toxic dose of acetaminophen ingested by the patient and the body weight, the ‎ physician prescribes a specific dose of NAC. There is always a risk of iatrogenic overdose of ‎ NAC which can cause different mild to severe temporary or permanent side effects, some of ‎ which can be life threatening. Here we report a rare case of iatrogenic NAC overdose following ‎ an error in calculation of the prescribed dose.‎The patient was a 2.5 years old boy that was brought to emergency room with overdose ‎ of acetaminophen syrup. The Physician prescribed 2 grams of intravenous NAC for him, but ‎ because of the miscalculation of the volume of the drug, the nurse infused about 20 grams of ‎ NAC (10 times the prescribed dose) to the patient. Immediately the patient became drowsy and ‎ developed decreased level of consciousness, stupor, repetitive intractable focal and generalized ‎ convulsions, decrease visual acuity and had prolonged hospitalization in intensive care unit and ‎ pediatric neurologic wards and perhaps will have permanent subtle intellectual and neurologic ‎ sequela. Considering the possible errors in the prescription and administration of some ‎ critical and less commonly used drugs especially those which have several different formulary ‎ and also considering their possible serious and life threatening side effects, it is recommended ‎ that the dose and volume of such medications be calculated meticulously by at least two trained ‎ persons. Also it is important to carry out the administration phases and check the patient’s ‎ symptoms more attentively and cautiously.

Abstract

Objective: Ceftiofur, a third-generation cephalosporin, is used as a usual antimicrobial drug in veterinary medicine. Positive efficiency of ceftiofur for treatment of retained fetal membrane (RFM) and acute puerperal metritis has been previously reported. Thus, this study was conducted to evaluate the efficiency of ceftiofur hydrochloride (CH) in prevention of uterine postpartum infections and improvement the fertility parameters in Holstein dairy cows. Methods: After parturition, 300 dairy cows affected with dystocia and RFM, from a single dairy herd, were randomly assigned into 2 groups (n=150). Group1 (control) was not treated but other group (CH) was subcutaneously treated with 2.2 mg/kg CH for 5 days. Results: CH could significantly reduce rate of uterine infections compared with control groups (P<0.01). Open days and first service rate were significantly lower in CH group compared with control group (P<0.01). It can be concluded that uterine infections and metritis are inevitable part of dairy cow transitional period. Injection of CH had beneficial effects on reduction the infections and thus it can be advised use of CH to reduce infections and increasing fertility rate in dairy cows affected with RFM and dystocia, before other control program.

Abstract

Objective: Soil temperature serves as a key variable in hydrological investigations to determine soil moisture content as well as hydrological balance in watersheds. The ingoing research aims to shed lights on potential of artificial neural networks (ANNs) and Neuro-Fuzzy inference system (ANFIS) to simulate soil temperature at 5-100 cm depths. To satisfy this end, climatic and soil temperature data logged in Isfahan province synoptic station were collected. Methods: The ANNs structure was designed by one input layer, one hidden layer and finally one output layer. The network was trained using Levenberg-Marquardt training algorithm, then the trial and error was considered to determine optimal number of hidden neurons. The number of 1 to 13 neurons were evaluated and subsequently considering a trial and error test and model error, the most suitable number of neuron of hidden layer for soil depths 5, 10, 20, 30, 50 and 100 cm was found to be 3, 4, 5, 4, 5 and 3 neurons respectively. Clustering radius was set as 1.5 for subtractive clustering algorithm. Results: Results showed that estimation error tends to increase with the depth for both ANNs and ANFIS models which may be attributed to weak correlation between the input climatic variables and the soil temperature at increasing depth. Result suggested that ANFIS approach outperforms ANN in simulating soil horizons temperature.

Abstract

Objective: Meningitis is life-threatening condition and examination of the Cerebrospinal fluid (CSF) may not give a precise diagnosis and prognosis of different types of meningitis. Bacterial meningitis is still a very common problem especially in many developing countries. The aims of study are to estimate the importance and significance of Lactate Dehydrogenase (LDH), protein and sugar in CSF of different types of meningitis. Methods: A total of 160 cases, aged between 1 month and 60 years, including patients with bacterial meningitis (n=50), pyogenic meningitis (n=46), viral meningitis (n=24) and a control group (n=40), were analyzed on the basis of data from the initial clinical examinations. Results: Significant increase in LDH level (P<0.001) were observed in the test group when compared to the control group. The LDH activity was significantly elevated in the CSF and serum (p < 0.001) in cases of pyogenic (PM) as well as tuberculosis meningitis (TBM). Bacterial meningitis is more common than non bacterial meningitis. The enzymatic activity of LDH although significantly raised in PM compared to TBM but there was no cutoff level to differentiate them. The LDH level did rise quite significantly in pyogenic meningitis.

Abstract

Objective: The level of dental and oral hygiene on elementary school age children is very low, so it can be increasing the incidence of dental and oral diseases which caused by various microorganisms. Mouthwash can keeping dental and oral hygiene, but many commercial mouthwash is still used alcohol as their ingredients, which can be giving side effects, therefore, we still needed used alternative mouthwash, which made from nano chitosan and nano calcium, derived from nature Xylotrupes Gideon. Methods: This is a experimental study with pre and post test control group design using total plate count method. Total is 27 subjects, aged 9 years. Processing data is done by statistical test Chi Square, and one way ANOVA with software of SPSS 23. Results: Results showed that serum concentration of glucose, cholesterol and triglyceride were significantly higher (p ≤ 0.05) when compared with the fluid from three follicles size categories (Small, Medium and large follicles in CL+ and CL- ovaries). The differences between follicle size categories in CL- ovaries were only significant for concentrations of glucose and triglyceride. The FF concentration of glucose and cholesterol in same follicle size categories (Small, Medium and large follicles in CL+ and CL- ovaries) were significant (P ≤ 0.05). Conclusions: Measurement results the quantity of bacteria suggested that decreased of bacteria colonies before and after gargle, on negative control 30%-73%, positive control 33%- 100%, the 250ppm concentration is 95% -100%, 500ppm and 750 ppm concentration is 100%. Nanoparticles of chitosan and calcium-based mouthwash formulation from X. gideon has the ability to reduce oral bacterial colonies quantity among elementary school age children. More high concentrations of mouthwash formulations which are used more low quantity of oral bacteria colonies.

Abstract

Objective: A field experiment was conducted in order to study the effect of phosphorus and manure application on agronomic performance and seed yield of groundnut. Methods: Factorial combination of two groundnut varieties (‘Werer 962’ and ‘Oldhale’), Three rates of phosphorus (0, 90 and 180 kg P2O5 ha-1) and three rates of manure (0, 5 and 10 ton ha-1) were laid out in randomized complete block design with three replication. Results: The combined application of 180 kg P2O5 ha-1 and 10 ton manure ha-1 resulted in the highest number of pods per plant and seed yield. The increase in number of pods per plant and seed yield at the highest combined application rates of the two fertilizers were 40 and 60%, compared to the control of the two fertilizers. Generally, the present study has shown that the integrated use of manure (10 ton ha-1) and inorganic phosphorus (180 kg P2O5 ha-1) fertilizer resulted in highest seed yield of groundnut compared to the application of either fertilizer alone.

Abstract

Objective: A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at wondo Genet Agricultural Research Center experimental site (at wondo Genet station). Methods: Two inter-row spacings (60 and 90 cm) and three intra-row spacings (30, 60 and 90 cm) were evaluated using two varieties, WGHibiscus-Jamaica and WG-Hibiscus-Sudan on a plot size of 3.6 m length x 4.2 m width. The experimental design was a randomized complete block design in factorial arrangement with 12 treatments in three replications. SAS (version 9) software was used to compute the analysis of variance. Results: The results revealed that varieties differed markedly in most of the studied parameters. Of the two varieties tested, variety WGHibiscus-Jamaican showed greater plant height, number of branches per plant, number of leaves/plant, leaf area, leaf area index, days to 50 % flowering, days to 95 % maturity, number of capsules/plant, fresh calyx yield/plant, dry calyx yield/plant, seed yield/plant, total number of capsules/ha, total fresh calyx yield/ha, total dry calyx yield/ha and total seed yield/ha. In contrast, variety WG-Hibiscus-Sudan matures earlier and had heavier 1000 seed weight than variety WG-Hibiscus-Jamaican. Number of capsules/plant, fresh and dry calyx yield/plant were influenced by interaction effects of variety; inter- and intra-row spacing. Moreover, fresh and dry calyx yield/plant, total fresh and dry calyx yield/ha were influenced by interaction effects of variety, inter- and intra-row spacing.

Abstract

Objective: An experiment was conducted at Wondo Genet Agricultural Research Center in the production season of 2013/14 and 2014/15 with the objective of identifying the best combination of intra and inter-row spacing for optimum plant population density of stevia. Methods: The experiment was conducted using five intra-row spacing (20cm, 25cm, 30cm, 35cm, and 40cm) and three inter-row spacing (40cm, 50cm and 60cm) with total treatment combination of fifteen that were laid out in factorial RCBD design with three replications. In 2013/14 cropping season the maximum fresh leaf weight (19467kg ha-1), fresh above-ground biomass (25002kg ha-1) and dry leaf weigh (7834kg ha-1) were obtained from the combined pacing of 20cm intra-row and 40cm inter-row spacing. In 2014/15 cropping season, the maximum fresh leaf weight (16470.1 kg ha-1) and (14433.9kg ha-1), fresh above-ground biomass (27547kg ha-1) and (23619.8kg ha-1) and dry leaf weight (4773.7 kg ha-1) and (4314.0 kg ha-1) were obtained from 20cm intra-row and 40cm inter-row spacing respectively. Results: Although the study showed that the highest Stevia herbage yield per unit area was recorded from the combined spacing of 20cm intra-row and 40cm inter-row spacing, considering the difficult condition we met during weeding and watering, we, therefore; suggest that the best combined intra-row and inter-row spacing for Stevia is 25cm x 40cm to attain maximum yield under appropriate management conditions at wondo genet and similar locations.

Abstract

Objective: Chamomile is one of the commercial medicinal plants produced in Ethiopia. Besides, it is priority crop in national aromatic and medicinal plants research project in the country. As chamomile production affected by production techniques this activity was conducted to identify the effect of seed storage duration and seedling raising methods on its seedling establishment. Methods: The experiment was conducted during 2015 at rain feed condition at wondogenet agricultural research center, south Ethiopia using randomized complete block design in three replications. Zero months, three month, six month, nine month and twelve month stored seeds were combined with direct sowing, seed bed raised and pot raised seedlings resulting in a total of fifteen treatments. Data on plant height, flower yield per plant, flower yield per hectare, number of flower per plant and average weight of ten flowers were collected and tested statistically. Results: Direct sowing and pot raised methods resulted in lowest and highest value in all parameters respectively. Least and largest values range from 35.37 to 60.08 for plant height, 43.88 to 51.77 for flower yield per plant, 4.87 to 5.74 for flower yield per hectare, 244.99 to 383.71 for number flower per plant and ranges from 1.51 to 1.57 for average 10 flower weight. One year old seedlings resulted in higher mean value for plant height, flower yield per plant, flower yield per hectare and average weight of 10 flowers. Zero month treatment resulted in the least values for flower yield per plant, flower yield per hectare and number of flower per plant parameters. However, even though seedling raising method resulted in very highly significant results in plant height and in number of flower per plant, in all seed storage durations treatments there was none significance results for all testing parameters. Besides, the interaction of seed storage duration and seedling raising method treatments were resulted in none significant result for all testing parameters.

Adult Hippocampal Neurogenesis and Memory

Authors: Sylvia Ortega-Martínez
(5 downloads)
Abstract

Adult neurogenesis, a concept emergent in the late 1990s, is the generation of new neurons in the adult brain. This process occurs thank to cells who have this proliferative feature, named as Neural Stem Cells (NSCs). Neural Stem Cells (NSCs) are primary progenitors who can generate the two neural types (neurons and glia). Classically it was assumed that NSCs are only present in the embryo, but today it is extensively known that are also present in the postnatal and adult brain, although the majority were found in embryo stage. According with Merkle et al. 2006, these cells are characterized by the following features: 1. They come from glial cells, 2. They are related linearly between adult and embryonic cells (since they are transformed from neuroepithelial cells to radial glia, and then they show astroglial cells characteristics), and 3. These cells are divided essentially asymmetrically leading to another intermediate progenitor (IPC) as a parent, and sometimes divided symmetrically, to increase the progeny (Ortega Martinez and Trejo, 2015). Meanwhile, intermediate progenitors (IPCs) are always divided symmetrically to amplify the number of progeny dividing (Merket et al., 2006). These symmetric divisions are an important determinant of the brain size, so those species with larger brains have a larger pool of intermediate progenitors (Marshall et al., 2005). These cells, in adults, are mainly found at the subventricular zone (SVZ), adjacent to the lateral ventricles and at the dentate gyrus (DG) of the hippocampus, known like subgranular zone (SGZ) the ‘imaginary line’ below granular zone of DG where these cells are found (see Fig. 1). However, there are evidences of the existence of these cells elsewhere in the adult brain, including the cortex (Feliciano et al., 2012) or the hypothalamus (Lee et al., 2012). These precursor cells are quiescent (usually non-dividing) that can be divided into different stimuli. When this happens, there are two possibilities; A) their division generates intermediate progenitor cells (IPC), which then gives rise to neurons; B) whereas if they come from astroglial progenitors, the result will be the generation of glial. The process of formation of neurons through intermediate progenitors is a longer process, as there are different types of intermediate progenitors known as 2a, 2ab, 2b and type 3 according to their stage of development and expressing markers, whereas astroglial progenitors have comparatively a lower proliferative capacity. However, intermediate progenitors send numerous processes before being symmetrically divided, motivated by local sensing factors (Noctor et al., 2004). The NSCs don’t only come from the nervous system but can be derived from embryonic stem cells (ES cells) or reprogrammed fibroblasts (Wernig et al., 2008). Different kinds of neural progenitor/stem cells basis have been established on their characteristics. There are two different populations known like: neural stem cells which show glial characteristics (Radial Glia Cells, RGLs), and intermediate progenitors (IPC). The latter are also divided into other types (2a, 2ab, 2b, 3). The classification of these cells and the markers used to identify them has created much controversy among scientists. However, there is a large consensus that the astrocytic NSC have many features, such as the expression of glial fibrilar acidic protein (GFAP), which has made us change our perception of glia (Merkle et al., 2006). Other studies (Kempermann et al., 2003) support the interpretation that radial astrocytes have a role as primary progenitors.

Abstract

This study was conducted at the Gorgan University of Agricultural Sciences and Natural Resources farm, Iran, Golestan province with about 600 mm annual rainfall in order to evaluate the effect of different sowing dates on Azivash (Corchorusolitorius) seed quality, using a randomized complete block design with three replications on 2013. Treatments were four sowing dates such as May 5, Jun 5, Jul 11 and Agu 6. After seed maturity and harvesting, a seedling growth tests were done for each sowing date treatment in four replications. It used 25 number seeds in each replication. Seedling growth test was performed by BP (between paper) method for 7 days at 25C in incubator. The results showed that effect of sowing date treatment was significant on normal seedling percentage, abnormal seedling percentage, non-geminated seeds percentage and radicle and hypocotyl length. Mean comparison results showed that maximum normal seedling was recorded in Jun 5, Jul 11 and Agu 6 sowing dates. Minimum non-germinated seeds were recorded in Jul 11 sowing date. Also, seeds of Jul 11 sowing date treatment had the highest hypocotyl and radicle length. With regard to these founding and positive correlation between radicle length and normal seedling percentage and hypocotyl and radicle length with abnormal seedling percentage Jul 11 sowing date is the best sowing date for Azivash (Wild okra) cultivation in Gorganregional at Golestan province because of production of highest normal seedling production, lowest non-germinated seeds and longer hypocotyl and radicle length that result to highest seed quality and vigor.

Abstract

The aim of this study is to evaluate the relationship between Body Mass Index (BMI) and the outcomes of isolated CABG (Coronary Artery Bypass Graft) performed in Shahid Madani Hospital of Khorramabad, Iran. Data was retrospectively collected from the medical records retrieved from the hospital records office. All patients who had undergone isolated CABG under cardiopulmonary bypass in the Cardiothoracic Unit from 2007 till 2013 were identified and their demographic and clinical data were collected. Clinical data included BMI, ejection fraction (EF), history of COPD, MI, CVA, diabetes mellitus, hyperlipidemia, hypertension and the main outcomes included pulmonary complications, renal complications, transfusion, duration of ventilation, reoperation, intensive care unit stay, hospital stay and death. Patients were divided into six groups according to the BMI as follows: group 1: (BMI < 18.5), group 2: (18.5 ≤ BMI < 25), group 3: (25 ≤ BMI < 30), group 4: (30 ≤ BMI < 35), group 5: (35 ≤ BMI < 40), group 6: (BMI ≥ 40). Finally, perioperative variables in the six mentioned groups were compared using appropriate statistical methods. The obtained data were analyzed using SPSS software. In this study, 648 patients met the inclusion criteria of the study. The average age of the patients in the study was reported to be 61.35 ± 10.72 years. The average BMI was reports as 26.3 ± 4.03. The average cardiopulmonary bypass time was compared between the various BMI groups, which showed that the highest average belonged to group V+ (groups V and VI) and the lowest average belonged to group I, but this difference was not statistically significant (PV > 0.05).There was no statistically significant difference between the groups in terms of the mean duration of mechanical ventilation, mean extubation time, drainage rate from the chest tube, and the amount of blood transfusion (PV > 0.05). Moreover, in 99.4% of the patients, broad-spectrum antibiotics, in 99.5% of the patients, inotropic drugs, and in 5.4% of the patients, IABP were used. Re-intubation was done in 3.1% of the patients. The average duration of hospitalization was 5.45 ± 1.48. There was no statistically significant difference between the groups in terms of hospitalization time (PV>0.05). In this study, 3.55% of the patients died. Smirnov and Kolmogorov tests showed that the distribution of quantitative variables is not normal in all the patients (PV<0.001). Therefore, to study the relationship between these quantitative variables, the Spearman correlation coefficient was used, which showed that none of the relationships were statistically significant. Therefore, considering these results, it can be suggested that if there is enough time before surgery, changes in the lifestyle of the individual be recommended so that he/she can attain a better health status. So, proper training and education can be very effective.

Abstract

Sunflower is one of the most important edible oil that growth of annual crops, it is grown over a widely area and is considered a crop adapted to an every environmental conditions, in order to study growth analysis of sunflower under sowing date and cultivars in dry condition a farm experiment was conducted a split plot arranged in a complete randomized block design with three replications in the Dry Research Station. Main plots consist of four level sowing dates with ten-day intervals from (March 30 - April 30) and subplots consist of three cultivars: Record, Zarya and Azargol. In different sowing dates observed that sunflower plants had slow growth in the primary stage afterwards had a quick growth, so in second sowing date sunflower plants had a quick growth with received 1220 growing degree days. Among different cultivars, Record, cultivar had highest crop growth rates and relative growth rate. Record cultivar with 125 days had highest growth duration and Zarya with 122 days had lowest growth duration so sowing date and cultivar had a significant effect on grain yield, grain yield reduced with delayed in sowing date and Record had a highest grain yield. Results of evaluation total dry matter (TDM) showed that Record cultivar had highest total dry matter also, among different cultivars statistical significant different was observed thus delay in sowing date reduced oil yield and highest oil yield was obtained from Record cultivar.

Abstract

Rambutan tree (Nepheliumlappaceum L.) is an important but a lesser known fruit tree in Ghana and has several nutritional and medicinal uses. Efforts to establish plantation of Rambutan in Ghana to ensure its sustainable use is challenged with unavailable planting materials because the seeds are recalcitrant in nature, loses viability easily when exposed to dryness. Seeds are therefore sown directly after extraction from fruit, even with this, most of the seeds do not germinate. A vegetative propagation technique by marcotting was devised to produce planting materials within 3 months. Four plant species of the same physiological age and spaced 4m apart were tested in complete random design fashion. Marcots were treated with four Indole-3-Butyric Acid (IBA) concentrations (0 Mg/L, 2000 Mg/L, 4000 Mg/L and 6000 Mg/L). Data collected were analysed on number of calluses formed in marcots, survival, shoot and root formation and root length. Comparable but highest survival of marcots was recorded in the 2000 Mg/L of IBA (14.67 +0.33) representing 97.78%. Marcots with 2000 Mg/L IBA concentration recorded highest mean number of roots (8.67 +0.33) formed. Root length ranged from 33.60 +0.52 in the 6000 Mg/L to 19.77 +1.26 in the control (0 Mg/L). Marcots with no IBA recorded 9.00 +0.58 as mean number of callused marcots. It is concluded that vegetative propagation technique by marcotting can be a suitable technique for Rambutan planting materials.

Abstract

Actinomycetes are an uncommon agent of human infections and its pathogenic factors are not known. The present study reports a rare case isolation of an actinomycete from a woman pleural fluid; the strain was identified by 16S rRNA gene sequence analysis. This strain was tested to produce an extracellular protease that hydrolysis gelatin, casein and hemoglobin on agar mediums. The purification of the enzyme was carried by ammonium sulfate precipitation, gel filtration and ion exchange chromatographies. The activity of protease was studied at different pH values and temperatures and in the presence of metallic ions and inhibitors. The molecular weight of the enzyme was determined by 12% Tricine SDS-polyacrylamide gel electrophoresis. The strain was identified as Streptomyces cinereoruber ssp. cinereoruber. Extracellular proteolytic enzyme was purified at 19.67 fold and a 3.0% recovery. The enzyme was characterized as having optimal activities at pH 11.0 and 50°C, it keeps more than 50% of activity at pH between 4.0 to 12.0 and it is thermostable at 30 and 40°C. Enzymatic activity is enhanced in the presence of metal ions and inhibited by EDTA and 1,10-phenanthroline. The molecular weight was 53 kDa. This study reports the first case isolation of Streptomyces cinereoruber ssp. cinereoruber from pleural fluid, the extracellular zinc-metalloprotease was proposed as candidate virulence factor.

Abstract

A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of Roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, WG-Hibiscus-Jamaica and WG-HibiscusSudan on a plot size of 3.6 m length x 4.2 m width. The experimental design was a randomized complete block design in factorial arrangement with 12 treatments in three replications. SAS (version 9) software was used to compute the analysis of variance. The results revealed that varieties differed markedly in most of the studied parameters. Of the two varieties tested, variety WG-Hibiscus-Jamaican showed greater plant height, number of branches per plant, number of leaves/plant, leaf area, leaf area index, days to 50 % flowering, days to 95 % maturity, number of capsules/plant, fresh calyx yield/plant, dry calyx yield/plant, seed yield/plant, total number of capsules/ha, total fresh calyx yield/ha, total dry calyx yield/ha and total seed yield/ha. In contrast, variety WGHibiscus-Sudan matures earlier and had heavier 1000 seed weight than variety WG-Hibiscus-Jamaican. The present study demonstrated that, the highest total fresh and dry calyx yield/ha were recorded when WG-Hibiscus-Jamaica and WG-Hibiscus-Sudan were planted at inter-row spacing of 60 cm and intra-row spacing of 30 cm.
