Sodium benzoate and potassium sorbate preservatives in food stuffs in Iran

A high-performance liquid chromatography method was applied for the determination of the levels of benzoate and sorbate in 400 food samples, including pickled cucumbers, canned tomato pastes, sour cherry jams, soft drinks, fruit juices and dairy products (UF-Feta cheeses, Lighvan cheeses, lactic cheeses, yogurts and doogh). The results showed that 270 (67.5%) of all samples contained benzoate ranging from 11.9 to 288.5 mg kg⁻¹ in lactic cheese and fruit juice, respectively. The levels of sorbate in 98 (24.5%) of the samples were 20.1 to 284.3 mg kg⁻¹ in doogh and fruit juice, respectively. Moreover, benzoate was detected in all dairy products ranging from 11.9 mg kg⁻¹ in lactic cheese to 91.2 mg kg⁻¹ in UF-Feta cheese. A low concentration of benzoate could originate naturally, due to specific biochemical mechanisms during cheese, yogurt and doogh maturation. In conclusion, a minimum level for benzoate in dairy products should be defined in the legislation. © 2015 Taylor & Francis

Faktor Risiko Kejadian Katarak pada Pasien Pria Usia 40-55 Tahun Dirumah Sakit Pertamina Balikpapan

Katarak terjdi akibat kekeruhan pada lensa mata yang mengakibatkan tergantungnya cahaya masuk ke dalam bola mata, sehingga penglihatan menjadi kabur dan lama kelamaan dapat menyebabkan kebutaan. Salah satu penyebab kebutaan terbanyak di seluruh dunia adalah katarak. Peningkatan kasus kejadian katarak terjadi di Rumah Sakit Pertamina Balikpapan selama 3 bulan terakhir pada bulan Januari hingga Maret yaitu 142 kasus, 173 kasus dan 188 kasus. Kejadian katarak berhubungan dengan penyebab diabetes mellitus, status ekonomi, kebiasaan merokok, pekerjaan terpapar UV, dan kebiasaan konsumsi protein. Tujuan penelitian ini adalah untuk menganalisis besarnya faktor risiko dengan kejadian katarak pada pasien pria usia 40-55 tahun di rumah sakit pertamina Balikpapan. Jenis penelitian yang digunakan dalam penelitian ini adalah studi observasional analitik dengan desain case control study. Sampel pada penelitian ini terdiri dari kasus dan control dengan menggunakan metode Purposive Sampling, sampel kasus yakni pasien pria usia 40-55 katarak yang berobat maupun screening di Rumah Sakit Pertamina Balikpapan Tahun 2017. Sampel kontrol penelitian ini adalah pasien pria usia 40-55 yang tidak menderita katarak yang berobat maupun screening di Rumah Sakit Pertamina Balikpapan Tahun 2017. Hasil penelitian menunjukkan bahwa diabetes mellitus (OR=4.419;95%Cl:1,991-9,809), Status ekonomi (OR=2.852;95%Cl:1,346-6,042), Kebiasaan merokok (OR=3,850; 95%Cl:1,785-8,304), Pekerjaan terpapar UV (OR=3.217; 95%Cl:1.523-6.795) merupakan faktor risiko terhadap kejadian Katarak. Sedangkan Konsumsi protein (OR=0.110; 95%Cl:0,046-0,264) merupakan faktor protektif kejadian katarak. Berdasarkan analisis multivariat menemukan bahwa Faktor risiko yang paling berpengaruh yaitu diabetes mellitus (p = 0,000) dan pekerjaan terpapar UV (p =0,001) terhadap kejadian katarak

Measurement of spray combustion processes

A free jet configuration was chosen for measuring noncombusting spray fields and hydrocarbon-air spray flames in an effort to develop computational models of the dynamic interaction between droplets and the gas phase and to verify and refine numerical models of the entire spray combustion process. The development of a spray combustion facility is described including techniques for laser measurements in spray combustion environments and methods for data acquisition, processing, displaying, and interpretation

Coronary Heart Disease Risk Factors Among Women Aged Older Than 45 Years Old in Makassar

Cardiovascular disease causes 8.6 million deaths of women every year, which is the major cause of death by one-third of all deaths of women in the world. Half of all deaths of women older than 50 years old is caused by cardiovascular and stroke diseases. This study aimed to analyze risk factors related to coronary heart disease among women aged older than 45 years at Dody Sarjoto Makassar Air Force Hospital 2016. The total of sample was 76 consisting of 64 cases of coronary heart disease and 12 non-coronary heart disease. Determination of sample used purposive sampling. Primary data were obtained through interview to respondents using questionnaire and direct interview. Data were analyzed by using contingency correlation coefficient (Exp (B)) test to identify significant relation between dependent and independent variables. Results found were hypertension (Exp (B) = 0.309), obesity (Exp (B) = 0.140), diabetes mellitus (Exp (B) = 0.164) and dyslipidemia (Exp (B) = 0.185), as proven having relation with coronary heart disease among women aged older than 45 years, and the factor which had the most significant relation was dyslipidemia

A Novel Single Nucleotide Polymorphism in Exon 4 of Insulin-Like Growth Factor-1 Associated with Production Traits in Bali Cattle

Insulin-like growth factor-1 (IGF-1) is one of the gene candidates that can be used in selection strategy by using DNA markers (marker assisted selection). Gene candidate strategy is a molecular biology techniques to identify quantitative trait loci directly, with the assumption that genetic variation associated to quantitative trait variation. This study was designed to identify any new mutations in exon 4 that can cause the IGF-1 gene polymorphism and then affect the production traits on Bali cattle. Single nucleotide polymorphism (SNP) discovery was conducted by using the direct sequencing technique. Genetic variation of the genes candidate was identified by using PCR-RFLP technique. The results of this study indicate the presence of a new SNP in exon 4 of IGF-1 gene caused by the T/C transition, which can be identified using Rsa1 restriction enzyme. Genotypic polymorphism of IGF-1/Rsa1 has a significant influence on birth weight, weaning weight and average daily gain of Bali cattle. CC genotype had a birth weight rate, weaning weight and average daily gain of: 15.64±1.83; 83.15±9.00, and 0.439±0.07 respectively, higher than the TT and CT genotype. IGF-1/Rsa1 can be used as a genetic marker for selection of birth weight, weaning weight, and daily body weight gain

PENGARUH LATIHAN KARET BAN DALAM DAN PEMBERAT KAKI TERHADAP KECEPATAN TENDANGAN SABIT PESILAT PUTRI EKSTRAKURIKULER PENCAK SILAT SMP NEGERI 2 GUNUNG GURUH KABUPATEN SUKABUMI 2017/2018

This study aims to determine the effect effect of exercise using rubber tires and ballast legs to speed sickle kick on the fighter's daughter extracurricular martial arts Junior High School 2 Gunung Guruh Sukabumi, This research uses quantitative methods with test and measurement techniques that are processed with parametric statistics. The sample of this research is female fighters totaling 22 people from extracurricular participants of Pencak Silat SMP Negeri 2 Gunung Guruh Sukabumi with random sampling technique. Based on the parametric statistical analysis it can be seen that K1 has an increase in the sickle kick speed of 45.92% for the right foot and 53.60% for the left leg. While K2 has a 22.35% crescend kick shot for the right leg and 27.27% for the left leg. Thus it can be concluded that K1 has a percentage increase in the sickle kick velocity greater than the percentage of increase in K2

Crossing Statistic: Bayesian interpretation, model selection and resolving dark energy parametrization problem

By introducing Crossing functions and hyper-parameters I show that the Bayesian interpretation of the Crossing Statistics [1] can be used trivially for the purpose of model selection among cosmological models. In this approach to falsify a cosmological model there is no need to compare it with other models or assume any particular form of parametrization for the cosmological quantities like luminosity distance, Hubble parameter or equation of state of dark energy. Instead, hyper-parameters of Crossing functions perform as discriminators between correct and wrong models. Using this approach one can falsify any assumed cosmological model without putting priors on the underlying actual model of the universe and its parameters, hence the issue of dark energy parametrization is resolved. It will be also shown that the sensitivity of the method to the intrinsic dispersion of the data is small that is another important characteristic of the method in testing cosmological models dealing with data with high uncertainties.Comment: 14 pages, 4 figures, discussions extended, 1 figure and two references added, main results unchanged, matches the final version to be published in JCA
