THE EFFECT OF “GREEN” ANTIOXIDANTS ON LIPID OXIDATION IN DRIED SALMON (Salmo salar) DURING STORAGE CONDITIONS

Nowadays food industries were concentrating on substituting the use of synthetic natural “green” antioxidants. Therefore, the present study focused on lipid oxidations in dried salmon (Salmo salar) with and without natural antioxidants (garlic powder, cinnamon) during different storage conditions, and a comparison was made with a synthetic antioxidant Butylated hydroxytoluene (BHT). Minced salmon fillet mass was divided into four equal parts and each part was treated with natural antioxidant under study except the control. Each of these four parts was dried in two different ways, half portion oven-dried and the other half portion freeze-dried. After 24 weeks, these samples were tested for peroxide value (PV), Thiobarbituric acid reactive substances (TBARS), total carbonyl content/water-soluble protein. According to the peroxide value (PV) results, it was noticed that the BHT was found to be the most effective antioxidant, followed by garlic and cinnamon for oven-dried salmon. Cinnamon was found to be more efficient than garlic in minimizing PV formation in freeze-dried salmon. In general, the initial study showed that freeze-drying was more efficient than oven drying. On the other hand, total carbonyl content for oven-dried salmon treated with cinnamon, garlic, and BHT, was found to be similar to the untreated salmon. Freeze-dried antioxidant treated salmon was generally found to possess more carbonyl content over time compared to the oven dried treated salmon

Solubility of Gliclazide in Transcutol + Water Co-solvent Mixtures at (298.15 to 333.15) K

The aim of present investigation was to determine the mole fraction solubility of a poorly water soluble antidiabetic drug gliclazide (GLZ) in mono-solvents and various Transcutol + water co-solvent mixtures at (298.15 to 333.15) K. The experimental solubility of GLZ was measured by shake flask method and resulting data was correlated with the modified Apelblat model at each temperature studied. Good correlation was observed between the experimental data of GLZ and calculated one with absolute relative deviation in the range of (0.050 to 5.680) %. The correlation coefficients were observed in the range of 0.9966 to 0.9995 which indicated good fitting of experimental solubility data. The lowest mole fraction solubility of GLZ was observed in pure water (1.9 × 10–6 at 298.15 K) whereas the highest one was observed in pure Transcutol (11.9 × 10–3 at 298.15 K). The enthalpies and entropies for GLZ dissolution were observed as positive values in the range of (15.742 to 40.551) kJ mol–1 and (52.801 to 121.721) J mol–1 K–1, respectively in all sample matrices. These results of thermodynamic parameters indicated that the dissolution of GLZ is endothermic and an entropy-driven process. Based on current solubility data, GLZ was considered as practically insoluble (poorly soluble) in pure water and soluble in Transcutol. These preliminary studies indicated that Transcutol could be used as a co-solvent for solubility enhancement of GLZ which could help in preformulation studies and formulation development of GLZ

An Empirical Analysis of the Factors Associated with Mushroom Cultivation: A Case of Dhaka

The analysis aimed to identify mushroom production and marketing problems by different stakeholders in Bangladesh, specifically in the Dhaka district. It also seeks to improve the mushroom marketing system for domestic markets. The research was carried out in the Savar Upazila, located in the Dhaka district. One hundred twenty-one farmers were randomly picked and asked questions using an interview schedule to collect data. Pearson's chi-squared test was utilized to investigate the degree to which socio-demographic factors and the response variable are related. In the end, a multivariate method known as logistic regression analysis is used to study the relationships between each predictor variable and the result variable that pertains to the respondents. The result revealed significant effects of gender, farmer's education, and information sources for intermediate and experienced mushroom cultivators. However, land size, scientific cultivation, sources of capital, packaging, and sale were stronger among expert mushroom farmers than the new and mediocre mushroom farmers. This research provides valuable insights to improve the mushroom marketing system for domestic markets

Efficacy and Safety of Methotrexate in Articular and Cutaneous Manifestations of systemic Lupus Erythematosus

Aim:  A prospective open-label study comparing the efficacy and safety of methotrexate (MTX) and chloroquine (CQ) in articular and cutaneous manifestations of systemic lupus erythematosus (SLE). Methods:  Consecutive SLE patients were randomly assigned to either 10 mg MTX weekly or 150 mg CQ daily during 24 weeks. Outcome measures were: numbers of swollen and tender joints, duration of morning stiffness, visual analog scale (VAS) for articular pain, physician global assessment index, patient global assessment index, SLE Disease Activity Index (SLEDAI), disappearance of skin rash and erythrocyte sedimentation rate (ESR). Results:  Forty-one patients consented to participate, 15 were allocated in the MTX group and 26 in the CQ group. Two patients on MTX dropped out due to side-effects and two in the CQ group, one due to side-effects and one due to inefficacy. Baseline demographic, clinical and laboratory parameters of the two groups were nearly identical. In both groups the clinical and laboratory parameters improved significantly over 24 weeks, except the ESR in the MTX group. The results of the outcome measures at the end of the trial did not differ significantly between the two groups, except morning stiffness (P < 0.05 in favor of the MTX group) and ESR (P < 0.01 in favor of the CQ group). Rise of serum alanine aminotransferase was observed in two cases in the MTX group and in none in the CQ group. Conclusion:  Low-dose MTX appears to be as effective as CQ in patients with articular and cutaneous manifestations of SLE, having an acceptable toxicity profile. Results of this prospective study need to be confirmed in a larger study

Cross-cultural adaptation and validation of a Bengali version of the modified fibromyalgia impact questionnaire

Background Currently, no validated instruments are available to measure the health status of Bangladeshi patients with fibromyalgia (FM). The aims of this study were to cross-culturally adapt the modified Fibromyalgia Impact Questionnaire (FIQ) into Bengali (B-FIQ) and to test its validity and reliability in Bangladeshi patients with FM. Methods The FIQ was translated following cross-cultural adaptation guidelines and pretested in 30 female patients with FM. Next, the adapted B-FIQ was physician-administered to 102 consecutive female FM patients together with the Health Assessment Questionnaire (HAQ), selected subscales of the SF-36, and visual analog scales for current clinical symptoms. A tender point count (TPC) was performed by an experienced rheumatologist. Forty randomly selected patients completed the B-FIQ again after 7 days. Two control groups of 50 healthy people and 50 rheumatoid arthritis (RA) patients also completed the B-FIQ. Results For the final B-FIQ, five physical function sub-items were replaced with culturally appropriate equivalents. Internal consistency was adequate for both the 11-item physical function subscale (α = 0.73) and the total scale (α = 0.83). With exception of the physical function subscale, expected correlations were generally observed between the B-FIQ items and selected subscales of the SF-36, HAQ, clinical symptoms, and TPC. The B-FIQ was able to discriminate between FM patients and healthy controls and between FM patients and RA patients. Test-retest reliability was adequate for the physical function subscale (r = 0.86) and individual items (r = 0.73-0.86), except anxiety (r = 0.27) and morning tiredness (r = 0.64). Conclusion This study supports the reliability and validity of the B-FIQ as a measure of functional disability and health status in Bangladeshi women with F

Latitude gradient influences the age of onset of rheumatoid arthritis : a worldwide survey

The age of onset of rheumatoid arthritis (RA) is an important outcome predictor. Northern countries report an age of RA onset of around 50 years, but apparently, variability exists across different geographical regions. The objective of the present study is to assess whether the age of onset of RA varies across latitudes worldwide. In a proof-of-concept cross-sectional worldwide survey, rheumatologists from preselected cities interviewed 20 consecutive RA patients regarding the date of RA onset (RAO, when the patient first noted a swollen joint). Other studied variables included location of each city, rheumatologist settings, latitudes (10A degrees increments, south to north), longitudes (three regions), intracountry consistency, and countries' Inequality-adjusted Human Development Index (IHDI). Data from 2481 patients (82% females) were obtained from 126 rheumatologists in 77 cities of 41 countries. Worldwide mean age of RAO was 44 +/- 14 years (95% CI 44-45). In 28% of patients, RA began before age 36 years and before age 46 years in 50% of patients. RAO was 8 years earlier around the Tropic of Cancer when compared with northern latitudes (p <0.001, 95% CI 3.5-13). Multivariate analysis showed that females, western cities, and latitudes around the Tropic of Cancer are associated with younger age of RAO (R (2) 0.045, p <0.001). A positive correlation was found between the age of RAO and IHDI (r = 0.7, p <0.01, R (2) 0.5). RA often begins at an early age and onset varies across latitudes worldwide. We postulate that countries' developmental status and their geographical and geomagnetic location influence the age of RAO.Peer reviewe
