This research developed a regional economic model to estimate the ex-ante impacts of biofuel production on the economy of the southeastern United States. The analysis focuses on biofuels produced using biochemical and pyrolysis technologies. The primary feedstocks considered include switchgrass (Panicum virgatum) and poplar (Populus spp.). The economic analysis modifies the Impact Analysis for Planning (IMPLAN) input-output model to determine the macroeconomic impacts of a mature industry producing biofuels using these technologies and feedstocks. Optimal facility locations are determined using a site locator model that minimizes the costs of procuring feedstock. Given a change in the land use caused by industry demand for feedstock, shocks to the farm economy are forward-linked to sectors supporting biofuel production. Key economic indicators analyzed include changes in employment and value added to the economy. System output is analyzed using a nonparametric bootstrap procedure to simulate the distributions of the impacts. The null hypothesis is that the economic impacts following the introduction of the industries are not different from baseline economic activity. Findings suggest that the net changes in employment and value added to the regional economy are positive, but modest. For example, job increases attributed to the advancement of the industries analyzed range between 0.18% and 0.95%. Total value added to the regional economy ranged between 0.15% and 0.83%.

Background: Multiple biochemical parameters related to cytolysis, cholestasis and/or liver failure, can be used to evaluate liver tolerance to antiretroviral (ARV) drugs. what parameters are most suitable for monitoring early hepatic tolerance in the developing countries? Objective: to evaluate liver tolerance to NVP (nevirapine) or EFV (efavirenz)- based regimens during the first six months. Method: This is a preliminary prospective cohort study with 125 naive ivorian HIV1-infected patients, by observing the level of ALT (alanine aminotransferase), AST (aspartate aminotrans- ferase), ALP (alkaline phosphatase), GGT (gamma-glutamyl transferase), and TBR (total bilirubin). Results: variable changes are noticed in the level of various biochemical parameters from M0 to M6. Nevertheless, we found that the values of these parameters studied fall within normal ranges except for GGT which showed an increased level with NVP-based regimen. Biological liver tolerance to NVP or EFV-based regimen was good at M3 and M6 during therapy. The percentage of patients who had elevated ALT activity had tripled with each ARV regimen from M3 to M6. We noticed a decrease in the median value of transaminases (ALT and AST) from M0 to M6. This decrease was statistically significant for patients on EFV-based regimen from M0 to M3 and from M0 to M6. The ALP enzymes were the least affected after initiation of therapy, regardless of the regimen taken. In general,we noticed an hepatotoxicity of grade 1 or 2, in the two ARV regimens. The hepatotoxicity of grade 3 or 4 were rare (only with transaminases and GGT). Conclusion: we suggest a study of longer duration involving more patients, probably limited to the monitoring of transaminases (ALT and AST) and GGT, due to the results more or less sensitive about them in our analysis.

Objective: The association between type 2 diabetes mellitus and certain endocrine disorders has the paucity of information and limited data in the province of Meisan (southern of Iraq). Hence, in the present study, an attempt was made to investigate the levels of plasma HbA1c, serum insulin resistance and levels of serum sex hormones in men and women of control and type 2 diabetic patients. Also, the present study aimed to explored the correlation coefficient (r) between insulin resistance and level of HbA1c, FSH, LH, Tt, progesterone and estradiol in men and women patients with NIDDM. Methods: One hundred Iraqi volunteers with abdominal obesity were selected in the present study. Fifty diabetic patients with NIDDM (26 men, and 24 women) aged between (37) and (65) years and 50 healthy individuals (25 men, and 25 women) aged between (36) and (65) years considered as control group. Complete medical history was taken from each subject and complete clinical examinations were performed for all volunteers. Then, the two groups were matched for their fasting blood sugar, BMI, insulin hormone;c-peptide, HbA1c, sex hormones and insulin resistance parameters (HOMA2-IR, HOMA%B and HOMA%S) were calculated using HOMA2 calculator software. Results: We found that insulin resistance demonstrated negative correlations (p 0.05) with levels of serum follicle stimulating hormone (FSH), luteinizing hormone (LH), total testosterone, progesterone and estradiol. While, there was a positive and significant correlation (p 0.01) with value of HbA1c in men and women NIDDM patients. Conclusion: We conclude that an increase in the level of insulin resistance is associated with increased level of blood HbA1c and decreased in level of serum sex hormones (FSH, LH, Tt, E2 and progesterone) in men and women of diabetic group. These behaviors might suggest that insulin resistance can be used as a potential biomarker for predicting dysfunction of sex hygiene in NIDDM patients in addition to glycemic co

Chromium is found in all phases of the environment, including air, water and soil. The contamination of environment by chromium has become a major area of concern. Chromium effluent is highly toxic to plant and is harmful to their growth and development. In present study, a pot experiment was carried out to assess the phytotoxicity of chromium in Hibiscus esculentus at different concentration (0.5, 2.5, 5, 10, 25, 50 and 100 mg·kg-1) of chromium metal. The phytotoxic effect of chromium was observed on seed germination, seedling growth, seedling vigor index, chlorophyll content and tolerance indices of Hibiscus esculentus. All results when compared with control show that chromium metal adversely affects the growth of Hibiscus esculentus by reducing seed germination and decreasing seedling growth. The toxic effects of chromium metal to seed germination and young seedling are arranged in order of inhibition as: 0.5 > 2.5 > 5 > 10 > 25 > 50 > 100 mg·kg-1 respectively. The toxicity of chromium metal to young seedling and their effects on chlorophyll content were increased with higher concentration of chromium in the soil system. The major inhibitory effect of chromium in Hibiscus esculentus seedling was determined as stress tolerance index (%). The present study represents that the seed and seedling of Hibiscus esculentus has potential to counteract the deleterious effects of chromium metal in soil.

In Bangladesh, Fish is a major source of daily protein intake of millions of people but most of the fishes are consumed here as fresh fish which is highly susceptible to damage during transportation and marketing. Therefore, an innovative approach was undertaken to process the fish to avoid damage and extend shelf-life while preserving the nutritional qualities to facilitate the more efficient use of fish as a source of protein and other essential nutrients. This study was conducted to develop some dried protein-enriched fish powders from some commonly consumed fish species in Bangladesh and the nutritional, sensorial, and safety qualities were assessed. Five indigenous abundant fish species including small indigenous fish (SIS) and carp fishes namely Awaous grammepomus, Channa punctata, Puntius puntio, Hypophthalmichthys molitrix and Labeo rohita were used for the preparation of dried protein-enriched fish powders. biochemical, trace elements, sensorial, total viable count (TVC), pH, peroxide value, and moisture reconstitution during 90 days storage period were performed by standard analytical methods. The moisture, protein, fat, ash, carbohydrate (including fiber), and energy contents were ranged from (6.84% to 8.85%), (70.80% to 75.80%), (5.85% to 8.04%), (7.66% to 9.19%), (3.14% to 6.01%) and (367.50% to 379.61% kcal)/100g respectively. Highest content of protein was found in A. grammepomus (75.80%) samples and the lowest in H. molitrix (70.80%) samples. Maximum calcium content was found in sample L. rohita (2.54 g/kg) and minimum in C. punctate as (2.43 g/kg). Maximum iron content was found in H. molitrix (0.15 g/kg) and minimum in A. grammepomus. As for the phosphorous content the L. rohita samples contained the highest (1.4 g/kg) and the lowest in C. punctate (0.73 g/kg) samples. The pH, peroxide value (mEq of O2/kg of fat), and moisture reconstitution (g/100g) during 90 days were ranged from (5.30 to 8.17), (8.60 to 16.77), and (6.84 to 13.83) respectively.

Medicinal plants are considered as natural sources of antioxidant compounds which may protect organisms against oxidative stresses. The aim of this study was to evaluate the potential of Cinnamon and Melissa officinalis L. (Lemon balm) on the improvement of oxidative stress in glass production workers. This clinical study was conducted on 32 glass production workers. They were asked to use 0.5 g of tea-Cinnamon and 3 g of Lemon balm as infusion for 30 days in the morning and evening each day. At the beginning and the end of the study, blood samples were taken from individuals to determine the level of fasting blood suger (FBS), aspartate transaminase (AST), alanintransferase (ALT), triglyceride (TG), cholesterol (CL), low-density lipoprotein (LDL), high-density lipoprotein(HDL) levels, lipid peroxidation (LPO), total antioxidant capacity (TAC) and sillies were measured in workers’ blood. At the end of experiment, data were subjected to the paired t-test analysis. Clinical examination was accomplished to record any abnormal signs or symptoms. After treatment, the high-density lipoprotein and TAC of serum significantly increased while the AST and LPO decreased. There were positive correlations between work history and initiative energy disorder of cognitive test. Probably tea-Cinnamon and Lemon balm possesses marked antioxidant activity and, therefore, it can be used to protect individuals from the oxidative stresses. Using supplementary antioxidants may be helpful in the treatment of workers.

The study of the effect of added quantity of the essential oil of Callistemon viminalis on the in vivo digestibility of Pennisetum clandestinum and some biochemical parameters on the West African Dwarf goat was conducted with nine old West African Dwarf goats. After the adaptation period, each animal received 900 and 100 g/day of Pennisetum clandestinum hay and concentrate respectively, associated with 0, 100 or 200 mg essential oil/kg of DM. The samples of 100 g of each ration, faeces and 10 ml of urine were collected and analyzed for chemical composition and the evaluation of ingestion and digestibility. Also blood samples were obtained from jugular vein of all goats after in vivo digestibility test for the dosage of biochemical parameters. The results of this study show that the ingestion of dry matter, organic matter and the fibers were significantly (p 0.05) higher on the goat with the ration FPc + HECv200. The digestibilities of these same components were equally higher with the ration FPc + HECv200 (71.00% and 69.00% respectively for the dry matter (DM) and organic matter (OM)). Retained (5.64 g/j) and digested (51.33) nitrogen were significantly (p 0.05) higher with the ration FPc + HECv200. The values of blood metabolites studied increased significantly (p 0.05) with added quantity of essential oil in the rations, except for albumin, globulin, glucose and the low-density lipoprotein (LDL). In general, the incorporation of essential oils of Callistemon viminalis in the ration improved ingestion, digestibility and biochemical parameters on the West African Dwarf goat.

The study aimed to evaluate the effect of the green alga Ulva lactuca and medicinal plant Nigella sativa extract on the activity of Staphylococcus aureus and Pseudomonas aeruginosa. The bacteria were incubated with the crude extracts and extracellular free potassium and phosphorus ions were measured in the medium. The levels of potassium and phosphorous were the maximum in the medium of S. aureus treated with N. sativa extract. The medium of P. aeruginosa incubated with U. lactuca extract was found to have the lowest phosphorous and the greatest potassium levels. The highest activity against P. aeruginosa was noticed with U. lactuca extract, where it caused reduction in the dry weight and glucose consumption of bacteria estimated by 28.41% and 41.09%, respectively. The antibacterial activity of N. sativa extract was the greatest against S. aureus and recorded 32.59% and 39.96% reduction in the bacterial dry weight and glucose uptake, respectively. Scanning Electron Microscopy study showed morphological changes in the cell wall of treated bacteria. The treatment of bacteria with the tested extract induced gene mutations. The results assessed the possible application of U. lactuca and N. sativa as a source of pharmacological benefits.

Purpose: We evaluated biochemical analysis results with the aim of discovering serum levels that have possible effects on the development of retinopathy of prematurity (ROP). Methods: A retrospective study was conducted between January 2017 and January 2018 on a total of 110 infants with 35 or less gestational weeks. The sample included 78 infants who had been diagnosed with different stages of ROP and 32 infants without ROP. Results from routine serum biochemical analyses, performed at birth and at one month after birth, were evaluated. The Independent Sample t-test and Mann-Whitney U test were performed to compare the data. Results: The infants with ROP were born at a mean of 28.0 (±2.1) weeks of gestation, weighing a mean of 1066 (±314) g, and the mean duration of stay in the incubator was 38.2 (±19) days. The infants without ROP were born at a mean of 29.6 (±2.6) weeks of gestation, weighing a mean of 1265 (±372) g. 59 infants (53.6%) were females, and 51 (46.4%) were males. Between infants with and without ROP, differences in the following levels were not statistically significant: glucose, blood urine nitrogen, creatinine, alanine aminotransferase, aspartate aminotransferase, albumin, total protein, direct bilirubin, indirect bilirubin, uric acid, and phosphorus. Serum magnesium (Mg) levels at birth in infants with ROP were significantly higher than infants without ROP (p = 0.014). Conclusions: Serum Mg levels at birth were found to be higher in infants with ROP than in those without ROP. The levels may be dependent on the mothers’ treatment of Mg for different medical reasons.
