Steroidal anti inflammatory drug betamethasone significantly alters level of striatal dopamine in a rat model of Parkinson’s disease

Many scientific efforts have been well done to investigate the effects of anti inflammatory agents on the degenerative brain diseases such as Parkinson’s (PD) or Alzheimer’s disease and their affiliated sings. Previously we showed the effectiveness of steroids on rigidity of PD and in the study for further mechanistic investigation of that observation the microdialysis technique was employed to determine the striatal dopamine changes in parkinsonian rats after administration of betamethasone (0.12, 0.24 mg/kg) respectively. Our findings showed us the significant increase in the striatal dopaminergic neurotransmission (P<0.05) after administration of betamethasone comparing to the controls. These observations suggest a new mechanism for betamethasone on striatum dopaminergic neurotransmission leading us to gather further evidence about effectiveness of betamethasone in PD

Demand analysis of food in Malaysia: A study of Malay ethnic

The objective of this study is to provide an insight into demand patterns of the Malay consumers for specific food categories in Malaysia. By utilizing Household Expenditure Survey 2004/2005, a system of equations of Linear Approximate Almost Ideal Demand System (LA/AIDS) model for 12 aggregated food products is estimated using a two-step estimation procedure. A Working-leser form of Engel function is also estimated to derive income elasticities from the estimated expenditure elasticities. This study shows that Malay consumers appear to have different food consumption patterns as compared to the general Malaysian diets. Malay consumers tend to increase their consumption of rice more than higher-value (meat and fish) and functional (vegetables and fruits) foods. Malay consumers are found to be very sensitive to the own-price of most of the food products, especially rice (-2.0241).Food, Linear Approximate Almost Ideal Demand System, Engel function

Analisis faktor-faktor Religiusitas yang mempengaruhi kinerja karyawan ( studi kasus di BMT Kecamatan Genuk )

Baitul Mal wa Tamwil (BMT) merupakan sebuah lembaga keuangan mikro yang berlandaskan prinsip syariah dalam melaksanakan transakasi keuangan. Namun yang menarik untuk dikaji ialah apakah ketika karyawan yang bekerja pada BMT yang memiliki perilaku Islami (religiusitas) dalam bekerja memiliki pengaruh terhadap kinerjanya. Rumusan masalah dalam penelitian ini adalah mengungkap apakah religiusitas (dimensi keyakinan, dimensi praktik agama, dimensi pengamalan, dimensi pengetahuan, dan dimensi pengalaman) mempunyai pengaruh pada kinerja karyawan BMT di Kecamatan Genuk dan seberapa jauh pengaruhnya. Dari hasil uji F variabel religuisitas (dimensi keyakinan, dimensi praktik agama, dimensi pengamalan, dimensi pengetahuan, dan dimensi pengalaman) secara bersama-sama (simultan) berpengaruh signifikan terhadap kinerja karyawan BMT di Kecamatan Genuk Semarang.Hal ini ditunjukkan dengan hasil dari uji ANOVA atau F test. Dari hasil analisis uji F didapat F hitung sebesar7,736> F tabel sebesar 2,5336 dan tingkat probabilitas sebesar 0,000 < 0,05. Probabilitas jauh lebih kecil dari 0,05 dan F hitung lebih besar dari F tabel maka, model regresi dapat dipergunakan untuk memprediksi religuisitas (dimensi keyakinan, dimensi praktik agama, dimensi pengamalan, dimensi pengetahuan, dan dimensi pengalaman) secara bersama-sama (simultan) berpengaruh signifikan terhadap kinerja karyawan Dalam penelitian ini hasil analisis regresi linear berganda yang terdapat dalam tabel diketahui bahwa koefisien determinasi yang dinotasikan R Square adalah 0,617 atau 61,7%. hal ini berarti sebesar 61,7% kemampuan dari hasil regresi penelitian ini dan menerangkan variabel dependen. Artinya 61,7% variabel kinerja karyawan bisa dijelaskan oleh variansi dari variabel indepanden religuisitas (dimensi keyakinan, dimensi praktik agama, dimensi pengamalan, dimensi pengetahuan, dan dimensi pengalaman), sedangkan sisanya (100% - 61,7% = 38,3%) dipengaruhi oleh variabel-variabel lainnya yang tidak diperhitungkan dalam analisis penelitian ini

Evidence of Engel curves in food away from home: A study of Malaysia

As Malaysians’ per capita income continues to grow, the food budget shares declines, which refers to Engel’s law. However, the statistics of the various Household Expenditure Surveys in Malaysia reported increasing food away from home (FAFH) budget shares which concerns whether the notion of Engel’s law can be extended to FAFH. By using Household Expenditure Survey 2004/05, the Heckman two-step procedure was applied with the Working-leser and other functional forms to conduct the Engel curves analyses. The empirical results exhibit the same observations as laid down in the Engel’s law. All the estimated expenditure elasticities of demand for FAFH were less than unity. Thus, this study verified that the notion of Engel’s law can be extended to FAFH in Malaysia.Engel’s law, food away from home, expenditure elasticity

Emerging food demand behaviors in Malaysia: Incorporating quality effects in demand analyses

In this study, the focus is on analyzing food demand behaviors in Malaysia. To be more specific, this study intends to estimate demand elasticities for twelve food categories with incorporation of food quality effects in the demand analyses. This study analyses the data from the Household Expenditure Survey 2004/2005 by Linear Approximate Almost Ideal Demand System (LA/AIDS) and unit value function. The estimated expenditure elasticities indicate that there will be growing demand for all the food categories, especially meat, fish, vegetables, oils and fats, and fruits. The own-price elasticities for rice, eggs, beverage, and oils & fats are more elastic than the rest of the food categories. This study also shows that there is quality effect in food demand.Food, demand behaviors. quality effects, demand analysis

Demand analyses of food in Malaysia: Effects of model specification and demographic variables

Demand analyses of food are deemed important to provide up-to-date indications of the demand behavior in future. This study is to determine which the model specification, as well as analyze the effects of demographic and socio-economic factors on of food demand in Malaysia. Household Expenditure Survey 2004/2005 data is analyzed by using Working Leser, Linear Engel model (LEM), Quadratic Engel model (QEM), and Linear Approximate Demand System (LA/AIDS). The empirical shows that LEM and QEM provide better results, in term of adjusted R2 and rationality of expenditure elasticities. Also, demographic variables improve the performance of all the selected models.demand analyses, food, Malaysia, expenditure elasticity

Demand for beef in Malaysia: Quality or Quantity?

With Malaysian government plan to increase production of beef and open the beef market to more abattoirs from other countries, domestic beef market has become more challenging. The domestic beef market is postulated to be available in a variety of qualities in future. Consumers do not only make decisions on how much to purchase but also at what qualities. This study is to analyze consumer evaluation of quality and quantity on demand for beef in Malaysia. A demand model incorporated consumer socio-economic variables and another applied demand analysis incorporated quality variable are estimated via two-stage least squares. Beef demand elasticities are estimated in the first demand model and a quality elasticity of demand for beef is estimated in the second applied demand analysis. The models are applied to a cross-sectional data set from Household Expenditure Survey 2004/2005. The results indicate that beef demand is inelastic to meat expenditure and to its own price. On another side, the results also indicate that beef demand is inelastic to quality. The elasticities in this study suggest that consumers substitute quantity for quality in demand for beef in Malaysia.beef, quality, quantity, demand elasticity, quality elasticity

Demand analyses of rice in Malaysia

As a typical developing Asian county, the growth in per capita income generally brings to diversification in Malaysians food basket. The most significant observation is the falling in per capita consumption of rice with continuous growth of demand for wheat based products. The objective of this study is to estimate the demand elasticities of rice in Malaysia, focusing whether rice is an inferior good. By using data from Household Expenditure Survey 2004/2005, this study obtains demand elasticities of rice, as well as for other 11 food items via Linear Approximate Almost Ideal Demand System (LA/AIDS) and Quadratic Almost Ideal Demand System (QUAIDS). The empirical results indicate that income elasticity of demand for rice (0.7104) is the highest compared to other food items in the LA/AIDS model, while income elasticity of demand for wheat (0.5087) is higher than rice (0.4712). Both of the income elasticities of demand for rice suggest that rice is not an inferior good in Malaysia. However, by comparing both estimates of demand elasticities and adjusted R2s, the QUAIDS model provides more plausible results than the LA/AIDS model.Rice, Wheat, Inferior Good, Linear Approximate Almost Ideal Demand System, Quadratic Almost Ideal Demand System, Income Elasticity
