- Evaluation of the cookies formulated with finger millet plant material for
antidiabetic property
Abstract: Cookies are the most popular bakery food consumed worldwide. The development of reduced-sugar soft cookies by using Finger Millet, Syzygium cumini L. (Jamun) and stevia extract was investigated. In addition to it, Buttermilk powder was used as a bulking agent to improve the flavor, color and texture of the cookies along with other ingredients like flour, margarine, salt, sodium bicarbonate, and water. The creamery method of production was used for cookie preparation. Amounts of water, stevia, and buttermilk powder and baking duration for each formulation were determined by preliminary experiments. Different formulations use different ratios to find out the best composition for cookies on the basis of palatability. After the selection of the best composition, cookies were prepared for the physiochemical, sensory and nutritional analysis. Sensory analysis was evaluated based on organoleptic properties: color, taste, aroma and overall acceptability on the basis of a 9-point hedonic scale. The physiochemical evaluation included total ash value, total water, and alcoholic extraction, and total moisture content. On the basis of nutritional value comparison, it was found that protein content is higher in our formulation than in other marketed products. Due to the high antioxidant potential and phenolic content of the Finger Millet cookie, it can be used as a therapeutic or functional food source for the treatment of overweight, obesity, and diabetes.

- Efficacy of a new Nutraceutical Formulation in preventing acute intestinal
inflammation: New therapeutic opportunities for the treatment of
diverticulitis'
Abstract: Acute diverticulitis is a painful, relatively sudden condition, characterized by the presence of low-grade inflammation in the colonic mucosa. Recent clinical trials supported the use of nutraceutical compounds in the treatment of patients with gastrointestinal disorders, including diverticulitis. To verify the hypothesis that nutraceutical ingredients my prevent diverticulitis development, we tested a combination of different natural active supplements, in a mouse model of acute intestinal inflammation. A nutraceutical formulation was administered daily in a prevention setting, by intrarectal enema. Inflammation severity was monitored using a Disease Activity Index (DAI) score, histological and endoscopic analysis, and quantification of Fecal Calprotectin (FC).Results showed that a combination of cranberry juice, pomegranate extract fruit in ellagic acid and inulin Fibruline®, prevented the development of experimental acute intestinal inflammation. This was confirmed endoscopically, in terms of reduced colon thickness and granularity of mucosal surface. Results were also confirmed histologically, not only by significant reduction of ulcerations, compared to control groups, but also by significant prevention of flogosis and inflammatory infiltration. Nutraceutical ingredients were also able to significantly reduce FC levels, confirming the anti-inflammatory properties of these dietary supplements.Our study supports the potential use of nutraceutical ingredients as a novel therapeutic approach to prevent acute diverticulitis.

- Chronic (52-week) oral toxicity study of herbal tea of Moringa stenopetala
and Mentha spicata leaves formulation in Wistar albino rats
Abstract: Background: Moringa stenopetala leaves have long been used to treat diabetes, hypertension, respiratory problems, and other diseases. The herbal formulation of Moringa stenopetala and Mentha spicata leaves was found to be more effective in lowering high blood pressure and blood sugar levels. Unlike its pharmacological properties, the long-term safety profile of this herbal formulation has not been investigated yet. Thus, this study investigated the long-term (chronic) oral toxicity of herbal tea of M. stenopetala and M. spicata leaves blended in rats. Methods: Wistar albino rats were randomly distributed into four groups (n = 10/sex/group), and then randomly assigned to a control group and three test groups. The control group (G I) received distilled water. The test groups (G II-IV) received 559.36, 1118.72, and 2237.44 mg/kg of herbal tea of M. stenopetala and M. spicata leaves blend respectively, for 360 consecutive days. During the treatment period, in-life parameters (mortality, clinical symptoms, body weight, and food intake) were evaluated. On the 361st day, hematological, serum biochemical, gross morphological, and histological parameters were investigated.Results: Throughout the 360-day treatment period, no herbal tea-related deaths, severe clinical symptoms, loss of body weight, or food intake were seen in any of the treated groups. Bodyweight, food consumption, organ weight, hematological, and serum biochemical findings showed no significant differences between the control and treated groups in both sexes. Macro-pathological and histopathological examinations of the major organs (liver, kidney, heart, pancreas, stomach, and spleen) revealed no herbal tea-related pathologic alterations. Conclusion: The findings indicate that long-term (360-days) oral administration of the herbal tea of M. stenopetala and M. spicata leaves blend is well tolerated by rats. Hence, it would be safe/low toxic up to a dose of 2237.44 mg/kg/day in chronic exposure.

- Oropharyngeal Pathogenic Bacteria: Carriage, Antimicrobial Susceptibility
Pattern and Associated Risk Factors among Febrile Patients
Abstract: Background: Pharyngeal and respiratory infections due to bacteria are global concerns especially because of the emergence of multi-drug resistant strains. The Oropharynx is one of the regions of the human body that is heavily colonized by microbial flora. So, the Oropharyngeal carriage is a major risk factor for an invasion and developing the disease. Therefore, this study was aimed at determining the carriage rate of potential pathogenic Oropharyngeal bacteria, associated risk factors, and antimicrobial susceptibility patterns among febrile patients at AHMC.Methods: A Cross-sectional study was conducted from November 2018 to April 2019. A systematic random technique was implemented to collect Oropharyngeal samples from 253 selected febrile patients. Specimen collection and processing were done following standard bacteriological procedures in Adama Public Health, Research, and Referral Laboratory. Antimicrobial susceptibility testing was done using the disk diffusion method in accordance with the Clinical and Laboratory Standard Institutes guideline. Data were analyzed using SPSS version 20. Results: Overall oropharyngeal bacteria carriage rate was 75.1%. A total of 190 bacterial organisms were isolated with 96 Coagulase-Negative Staphylococci (CNS), 55 Streptococcus pyogenes, and 19 Staphylococcus aureus were dominant isolates among gram-positive. Klebsiella pneumoniae, Neisseria meningitides, Moraxella catarrhalis, and Escherichia coli were among gram-negative bacteria isolates. Living in urban, cigarette smoking, and poor oral hygiene was significantly associated with the Oropharyngeal bacterial carriage rate. The majority of CNS, S.aureus, and S. pyogenes were resistant to different classes of antibiotics. Conclusion: Potentially pathogenic Oropharyngeal bacterial colonization rate was high. Place of living and behavioral factors are risk factors that were associated with bacterial colonization of the oropharynx. Several bacterial isolates were resistant to frequently prescribed antibiotic classes. Therefore, determining the antimicrobial susceptibility pattern of the isolates is important to intervene and prevent the risk of infection and also the emergence of multiple drug-resistant strains and disease management.
