Effect of rosemary (Rosmarinus officinalis) extract on weight, hematology and cell-mediated immune response of newborn goat kids

This study aimed at evaluating the effects of different levels of rosemary (Rosmarinus officinalis) extract on growth rate, hematology and cell-mediated immune response in Markhoz newborn goat kids. Twenty four goat kids (aged 7 +/- 3 days) were randomly allotted to four groups with six replicates. The groups included: control, T1, T2 and T3 groups which received supplemented-milk with 0, 100, 200 and 400mg aqueous rosemary extract per kg of live body weight per day for 42 days. Body weights of kids were measured weekly until the end of the experiment. On day 42, 10 ml blood samples were collected from each kid through the jugular vein. Cell-mediated immune response was assessed through the double skin thickness after intradermal injection of phyto-hematoglutinin (PHA) at day 21 and 42. No significant differences were seen in initial body weight, average daily gain (ADG) and total gain. However, significant differences in globulin (P 0.05), and white blood cells (WBC) (P 0.001) were observed. There were no significant differences in haemoglobin (Hb), packed cell volume (PCV), red blood cells (RBC), lymphocytes and neutrophils between the treatments. Skin thickness in response to intra dermal injection of PHA significantly increased in the treated groups as compared to the control group at day 42 (P 0.01) with the T3 group showing the highest response to PHA injection. In conclusion, the results indicated that aqueous rosemary extract supplemented-milk had a positive effect on immunity and skin thickness of newborn goat kids

The effect of 7.5% Povidone-Iodine versus 0.2% Chlorhexidine on Microbial Count of Surgical Site in Abdominal Surgery: A Randomized Clinical Trial

Background: One of the most common preventive methods of Surgical Site Infection (SSI) is preoperative skin preparation. Selecting the skin antiseptic before surgery is an important step that can reduce SSI risk. Aim: The present study was performed with aim to compare the effect of 7.5% povidone-iodine (PVP-I) and 70% alcohol versus 0.2% chlorhexidine (CHG) and 70% alcohol on the microbial count of the surgical site in the abdominal surgery. Method: This double-blind randomized clinical trial study was conducted between March 2017 and July 2018 at the educational-therapeutic centers of Iran University of Medical Sciences. The patients aged ≥18 years who underwent elective abdominal surgery were randomly assigned into two groups to have their skin cleaned before surgery with CHG-alcohol or PVP-I-alcohol. Also, before skin prep, after the primary prep and after the secondary prep, microbial cultures were taken. Data analysis was performed using SPSS (version 16) and Chi-square, Fisher's exact, Kolmogorov-Smirnov, Wilcoxon and U-Mann-Whitney tests. P<0.05 was considered statistically significant. Results: The microbial counts mean differences before and after skin preparation with PVP-I-alcohol were significant (P0.05). Implications for Practice: This study did not demonstrate an overall superiority of 2% CHG over 7.5% PVP-I skin preparation solution or vice versa. Both groups can be used to prepare patients' skin before abdominal surgery due to the affordability conditions and availability

Outsourcing and scheduling for a two-machine flow shop with release times

<p>This article addresses a two-machine flow shop scheduling problem where jobs are released intermittently and outsourcing is allowed. The first operations of outsourced jobs are processed by the first subcontractor, they are transported in batches to the second subcontractor for processing their second operations, and finally they are transported back to the manufacturer. The objective is to select a subset of jobs to be outsourced, to schedule both the in-house and the outsourced jobs, and to determine a transportation plan for the outsourced jobs so as to minimize the sum of the makespan and the outsourcing and transportation costs. Two mathematical models of the problem and several necessary optimality conditions are presented. A solution approach is then proposed by incorporating the dominance properties with an ant colony algorithm. Finally, computational experiments are conducted to evaluate the performance of the models and solution approach.</p

Rotation Invariant Retina Identification Based on the Sketch of Vessels Using Angular Partitioning

Abstract — In this paper, we propose a new retina identification system using angular partitioning. In this algorithm, first all of the images are normalized in a preprocessing step. Then, the blood vessels ’ pattern is extracted from retina images and a morphological thinning process is applied on the extracted pattern. After thinning, a feature vector based on the angular partitioning of the pattern image is extracted from the blood vessels ’ pattern. The extracted features are rotation and scale invariant and robust against translation. In the next stage, the extracted feature vector is analyzed using 1D discrete Fourier transform and the Manhattan metric is used to measure the closeness of the feature vector to have a compression on them. Experimental results on a database, including 360 retina images obtained from 40 subjects, demonstrated an average true identification accuracy rate equal to 98 percent for the proposed system. Keywords—Human identification, Retina identification, Sketch, and Angular partitioning

Comparison of the Effect of Preoperative Skin Prepartion with Povidone-Iodine and Chlorhexidine-Gluconate on Surgical Site Infection in Laparotomy Patients

Background and Aim: Surgical site infection (SSI) is one of the most common health-care associated infections. Using proper antiseptic solutions for preoperative surgical site skin preparation (skin prep) is one of the methods to reduce SSIs. The purpose of this study was to compare the effect of preoperative surgical site skin preparation with povidone-iodine and chlorhexidine-gluconate on the rate of SSI in laparotomy patients. Materials and Methods: A total of 70 Laparotomy surgery patients who referred to Firoozgar hospital in Tehran from May to September of 2021 were included in this clinical trial. Patients were randomly allocated into two groups which were treated with povidone-iodine(PVI) or chlorhexidine-gluconate (CHG) for surgical site skin prep. Skin prep was done with standard rotational method in two steps by the researcher for each group by using of PVI and CHG. SSI incidence was assessed by a researcher-made check list and also over post-surgical follow up visits by the surgeon. We used Fischer’s exact test, t-test, Chi-square and Cochrane’s Q-test to analyze the collected data. Results: SSI was seen in five patients (14.29%) of PVI group and one patient (2.86%) of CHG group. Although the SSI incidence in PVI group was 5.54 times more than CHG group, still the difference wasn’t statistically significant (P=0.198). Comparing the incidence of SSI’s in 24 hours after surgery (0%) and 30 days after surgery (8.57%) in both groups revealed that using these antiseptics for skin prep was effective in preventing SSI (P<0.001). SSI incidence was also associated with two days of patient’s hospital admission time (P=0.001). Conclusion: The result of this study revealed that the occurrence of SSI in PVI group was 5.54 times more than CHG group. However, the difference was not statistically significant. So both of these antiseptics can be used for surgical site skin prep
