Progesterone Therapy Administered 24 hours Before Embryo Transfer in ICSI Cycle Improves Embryo Implantation and Pregnancy in Women With Luteal Phase Defect.

Background: Ovulation induction by human menopausal gonadotrophin (HMG) results in temporal luteal phase defect. Luteal support therapies are required to support embryo implantation in stimulated cycle especially in luteal phase defect infertile women.  Objective: The objective of the present study was to investigate the clinical significance of progesterone, aspirin and HCG on human embryo implantation in women with luteal phase defect following ICSI and embryo transfer (ET). Patients and Methods: The female patients were divided into six groups depending on the type of the luteal support protocols (LSP). Group 1 (No= 54), received 10 mg oral progesterone (P), group 2 (No= 35) received P plus HCG, group 3 (No= 59) received P plus HCG plus oral aspirin, group 4 (No= 47) received vaginal P administered 24 hours before embryo transfer plus oral aspirin, group 5 (No= 40)  received vaginal P administered 12 hours after embryo transfer plus oral aspirin and group 6 (No= 46) received intramuscular P plus oral aspirin. The LSP were continued for at least 12 weeks, when the BHCG test was positive, (tested two weeks after embryo transfer). Results: Statistical analysis of the clinical data showed no significant differences between the LSP in regard to patient's age, body mass index (B/M2), basal FSH/LH ratio and estradiol concentration at the day of HCG injection. The ICSI rate, percentages of embryos developed in vitro, and the numbers of the transferable quality embryos were similar in all groups (P>0.05). The pregnancy rate was significantly higher (P < 0.05), in group 4 compared to other groups (38.66% versus 24.51%(G 1), 22.53% (G 2), 28.66% (G 3), 25% (G 5), 21.60% (G 6). The percentages of viable fetal sac development per patient were 31.49 (17/54), in G 1, 42.86 (15/35), in G 2, 49.16 (29/59), in G 3, 59.58 (28/47), in G 4, 32.50 (13/40), in G 5, and 34.79 (16/46), G 6. The percent of viable gestation sac was significantly higher in group 4 compared to other groups (P < 0.05). Concl u s i o n s : The administration of 400 mg /day vaginal progesterone 24 hours before ET and 100 mg/day aspirin five days after ET results in significant improvements in pregnancy and embryo implantation rates and development of viable fetuses in luteal phase defect infertile women undergoing ICSI-ET

Improvement of Production Quality by using Six Sigma Technique:

<p>As a result of lack of conformity of the outer diameter of the filling piston of plastic syringe to the specifications set out in the design map and the increased demand for its  products from the Medical syringes factory – Babylon. The research conducts the necessary investigations and  analysis of the production process as most of the units rejected by fact that the outer diameter of the filling piston is smaller than the minimum specification and units returned to work  due to the fact that  the outer diameter larger than the upper limit of the specification.</p><table cellspacing="0" cellpadding="0" width="100%"><tbody><tr><td><div class="shape"><p dir="rtl"><strong>13</strong></p></div></td></tr></tbody></table><p>The research aims firstly to examine the outer diameter of the filling piston through the use of the control chart of the variables represented by the average , and its impact on the production process capability because the increase in diameter specification leads to an increase in the pressure imposed on the lining of the cylinder, causing difficulty in piston movement and a decrease in diameter specification which leads to loose the process capability to prevent leakage of fluid, causing air to enter as well as to speed the movement of the piston, which negatively affects human life in both cases. Secondly, study the possibility of improving the production process capability by using advanced levels of the sigma.</p><p>The results showed that the production process in the case of a disciplined and follows a normal distribution, the pointer of  the production process capability is equal to (0.55) and the factory works within the level of Sigma equal to (1.65). The proportion of a damaged product is (15.8 %) and rework (0.99 %).</p><p>In order to  reduce the proportion of damaged product, this paper introduces a quality plan depending on ( ±0.025) as tolerance limits instead of ( ±0.05) to increase sigma level by 202%.</p

Purification and Characterization &#946; - lactamase produce from local isolate Klebsiella pneumonia

Beta-lactamase was purified from local isolate Klebsiella pneumonia by several steps included precipitation with ammonium sulphate at 20-40% saturation, DEAE- ion exchange chromatography and gel filtration on Sephacryl S-200 column. The obtained purification fold and recovery were 32.66; 47.04% respectively. The characterization of the purified beta-lactamase showed that the molecular weight was about 4000 daltons as determined by gel filtration.Purified enzyme had an optimal pH of 7 for activity and an optimal stability between pH 6.5-7.5, results shows that the optimal temperature appear to be 35 ? C .During storage the enzyme retained 72% at -20 ? C and retained 25% of the activity at the same period at 4 ? C

Phytochemical evaluation, antimicrobial and anticancer properties of new “oligo grapes” supplement

© The Author(s) 2019 This research presents complete data about phytochemical analysis and biological activities of a new dietary supplement for commercial use “Oligo Grapes” (OG), and its individual constituents: lyophilized pomace (LP), clay supplemented with red wine extract, lyophilized pomace ethanolic extract (PE), and red wine extract. OG, as a commercially available food supplement, has not been previously tested for its biological activity. Now we want to present new data about its phytochemical screening, antioxidant and antibacterial activities, and anticancer properties with respect to its cytotoxicity and effects on redox status in colon cancer cell lines. The tested extracts expressed strong antibacterial activity against Proteus mirabilis and Proteus mirabilis ATCC 12453, where the synergy of contents inside the supplement demonstrated a higher influence on the bacteria than its separately tested constituents. Among the investigated extracts, PE, as the extract with the highest phenolics concentration, had remarkable cytotoxic activity on HCT-116 and SW-480 colon cancer cells. Also, the treatments modulated redox status in the investigated cancer cells, by inducing oxidative and nitrosative stress, which could be one of the preferred mechanisms of the anticancer action. Based on the achieved antimicrobial and anticancer properties, there is a need for producing different food supplements and nutritional products originating from grapes. In this respect, the food supplement OG and its health benefits deserve scientific attention and further research
