Abstract
Bacterial resistance to different antimicrobial agents is growing with alarming speed, especially when bacterial cells are living in biofilm. Hybrid nanoparticles, synthesized through the green method, hold promise as a potential solution to this challenge. In this study, 66 actinomycete strains were isolated from three distinct marine sources: marine sediment, the algae Codium bursa, and the marine sponge Chondrosia reniformis. From the entirety of the isolated strains, one strain, S26, identified as Saccharopolyspora erythrea, was selected based on its taxonomic position and significant antimicrobial activity. Using the biomass of the selected marine Actinobacteria, the green synthesis of eco-friendly silver carbonate nanoparticles (BioAg2CO3NPs) is reported for the first time in this pioneering study. The BioAg2CO3NPs were characterized using different spectroscopic and microscopic analyses; the synthesized BioAg2CO3NPs primarily exhibit a triangular shape, with an approximate size of 100 nm. Biological activity evaluation indicated that the BioAg2CO3NPs exhibited good antimicrobial activity against all tested microorganisms and were able to remove 58% of the biofilm formed by the Klebsiella pneumoniae kp6 strain.

Abstract
Cooling of beams of gold ions using electron bunches accelerated with radio-frequency systems was recently experimentally demonstrated in the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. Such an approach is new and opens the possibility of using this technique at higher energies than possible with electrostatic acceleration of electron beams. The challenges of this approach include generation of electron beams suitable for cooling, delivery of electron bunches of the required quality to the cooling sections without degradation of beam angular divergence and energy spread, achieving the required small angles between electron and ion trajectories in the cooling sections, precise velocity matching between the two beams, high-current operation of the electron accelerator, as well as several physics effects related to bunched-beam cooling. Here we report on the first demonstration of cooling hadron beams using this new approach.

Abstract
According to "OMS" we are old at age 65. Because of the ageing population (life expectancy has increased in Europe) and medical progress, more and more old patients are addressed to cardiac rehabilitation centers. Ageing is a physiological process which varies between individuals, and in the same person organ ageing also differs. Old patient has usually several pathological diseases. Because old patient has restricted functional reserve, acute illness could get him closer to the decompensation area. Complications are more frequent in ageing people, and often need a specific initial treatment which delays rehabilitation. Rehabilitation program of old non-disabled patient is not different from that addressed to youngers. The main objective for dependent people is to restore the ability to perform activities of daily living. Correction of vascular risk factors and therapeutic education are also valuable in elderly. For patients with difficulty to remember or to understand instructions, family help is valuable when possible. The benefit of the rehabilitation in the elderly is demonstrated by several studies.

Abstract
PURPOSE Considering potential roles of soluble receptor for advanced glycation end products (sRAGE) and placental growth factor (PlGF) in ovarian function and embryo implantation, in the present study we have evaluated the association of these factors and also PlGF/sFlt-1 ratio with the ovarian response and implantation rate by dividing patients according to the OSI. METHODS In a cross-sectional study, 90 infertile women who were undergoing ICSI cycle using long protocol were recruited. The patients were divided according to ovarian sensitivity index (OSI). ICSI cycle outcomes were evaluated for each patient and PlGF, sFlt-1 and sRAGE levels of follicular fluid were assayed using commercial ELISA kits. RESULTS Follicular fluid (FF) sRAGE levels and PlGF/sFlt-1 ratio were statistically greater in high-responder women than other responders (p < 0.05). Positive correlations were obtained between sRAGE level with the number of oocytes, follicles and OSI level. sRAGE levels with cutoff value of 4.83 (ng/ml) for evaluating the pregnancy outcome showed 81.8 % sensitivity and 60.7 % specificity. Furthermore, there were positive associations between PlGF/sFlt-1 ratio with the number of oocytes, embryos and OSI level. CONCLUSION In conclusion, the results of current study supported that good ovarian response is independent of pregnancy outcome. Our results showed that FF levels of sRAGE and PlGF/sFlt-1 ratio could be used as markers for determining the high-responder women. Also, FF sRAGE levels could be a good predictor for ART outcome.

Abstract
STUDY QUESTION Does the intrauterine administration of hCG immediately after oocyte retrieval in antagonist cycles with ICSI and fresh embryo transfer (ET) influence the implantation rate or chemical and clinical pregnancy rates? SUMMARY ANSWER The intrauterine administration of hCG after oocyte retrieval increases the implantation rate and chemical and clinical pregnancy rates. WHAT IS KNOWN ALREADY Over half of IVF/ICSI cycles fail due to implantation failure. Intrauterine administration of hCG, a few minutes before ET, increased the implantation and pregnancy rates in most but not in all studies. The effect of intrauterine administration of hCG, after oocyte retrieval, has not yet been studied. STUDY DESIGN, SIZE, DURATION The study was a parallel, triple-blind randomized clinical trial (RCT) performed from September 2015 to February 2016, in a university hospital. We recruited women undergoing antagonist ovarian stimulation, ICSI and ET. For an effect size of 0.2, power of 80% at a significance level of 0.05, we needed 150 participants. Accounting for a 7% dropout rate, a total of 160 women was considered appropriate. A computer-generated randomization list with a block size of 4, with 1:1 allocation was used. The treatment allocation was placed in a sealed, opaque, envelope and picked up consecutively. Immediately after oocyte retrieval, patients in the intervention and control groups were treated with intrauterine injection of hCG and saline, respectively. Participants underwent ET on Day 3. A beta-hCG test was done at 2 weeks. If positive, three transvaginal-ultrasonographies (TVSs) were done at 3, 4 and 10 weeks after ET. The participants were called up thereafter and questioned about the continuity of their pregnancy. PARTICIPANTS/MATERIALS, SETTING, METHOD Of 1990 women attending the infertility clinic of our university hospital, 508 were IVF/ICSI candidates during the study period, and 245 of the patients on an antagonist cycle met the criteria to be invited into our trial. Inclusion criteria were normal ovarian reserve, age ≤41, undergoing ICSI, and fresh ET and normal TSH and prolactin. Uncontrolled chronic disease, severe hydrosalpinx, severe endometriosis, morphologic embryo deficiencies, non-obstructive azospermia and high risk of severe ovarian hyperstimulation syndrome were criteria for exclusion. After taking an informed consent, a total of 158 participants were recruited, of which 80 were randomly allocated to receive intrauterine 500 IU hCG in up to 0.5 ml normal saline and 78 to receive intrauterine 0.5 ml normal saline immediately after oocyte retrieval, during general anaesthesia. ICSI was performed conventionally. The 4-8 cell embryos were transferred on the third day after oocyte retrieval. Implantation rate, chemical and clinical pregnancy rates were analysed and compared between the two groups. MAIN RESULTS AND THE ROLE OF CHANCE Patients' demographic and baseline characteristics were comparable. The clinical results showed statistically significant differences between the two groups regarding the biochemical pregnancy rate (59.2 versus 31.3%; P = 0.001; odds ratio (OR) = 1.88; 95% CI, 1.26-2.82; risk difference (RD) = 27.8; 95% CI, 11.2-42.3), implantation rate (37 versus 17%; P = 0.012; OR = 2.29; 95% CI, 1.02-5.14; RD = 20.2; 95% CI, 5.4-33.8), clinical pregnancy rate (50.7 versus 16.4%; P < 0.001; OR = 3.08; 95% CI, 1.71-5.55; RD = 34.3; 95% CI, 18.7-47.6) and ongoing pregnancy rate (40.1 versus 13.4%; P = 0.001; OR = 3.04; 95% CI, 1.55-5.93; RD = 27.4; 95% CI, 12.7-40.6). The abortion and ectopic pregnancy rates were not statistically different between the two groups. LIMITATIONS, REASONS FOR CAUTION The insertion of an intrauterine insemination catheter and the injection of a small amount of saline into the uterine cavity (without hCG) may also have some impact on implantation. This effect could be studied by comparing this intervention with another study group without any intrauterine injection.There are no specific side effects mentioned in the literature for the intrauterine administration of hCG, neither were any observed in our study, but it is best to be cautious about probable side effects, because this type of intervention is relatively new and experimental, and deserves more studies before being entered into routine clinical practice. WIDER IMPLICATIONS OF THE FINDINGS Intrauterine administration of hCG immediately after oocyte pick up increases its effectiveness; however, further investigations are required before this procedure can be recommended for clinical practice. STUDY FUNDING/COMPETING INTERESTS This study was supported by the Women's Health Research Center, Tabriz University of Medical Sciences, Iran. No external funds were used. The authors have no conflicts of interest to declare. TRIAL REGISTRATION NUMBER IRCT201206165485N4. TRIAL REGISTRATION DATE 2 September 2015. DATE OF FIRST PATIENT'S ENROLMENT 2 September 2015.

Abstract
Despite recent advances in perinatal care, Preterm Premature Rupture of Membranes (PPROM) continues to lead to important obstetric complications. This study was aimed to evaluate the role of sonographic measurement of myometrial thickness in prediction of latency interval in women with PPROM. This analytic- descriptive and case- control study was performed on pregnant women with PPROM presenting to Tabriz Al-Zahra Hospital since 2006 to 2008. Thirty pregnant women with PPROM and 30 pregnant women with normal pregnancy were enrolled. Mean gestational age was 30.60 +/- 1.99 week and in case and 31.13 +/- 20.01 week in control group (p = 0.307). Mean gravidity was 1.63 +/- 0.49 in case and 1.47 +/- 0.50 in control group (p = 0.210). Mean parity was 0.53 +/- 0.62 in case and 0.57 0.50 in control group (p = 0.819). Mean anterior myometrial thickness was 8.23 +/- 2.59 mm in case and 7.71 +/- 1.45 mm in control group (p = 0.344). Mean posterior myometrial thickness was 8.90 +/- 2.86 mm in case and 8.12 +/- 1.54 mm in control group (p = 0.197). Mean fundus myometrial thickness was 9.10 +/- 3.54 mm in case and 8.77 +/- 1.77 mm in control group (p = 0.648). Mean latency interval of women with PPROM was 18.70 +/- 20.68 day and mean sonography to labor interval was 57.30 +/- 16.14 day (p < 0.01). Mean latency interval of women with PPROM was significantly shorter than mean sonography to labor interval in control group patients (p < 0.05). In our study, 50% of women in 10 first days after PPRM labored and only 43.3% of women labored in 7 first days after PPROM. In this study, significant correlation was not found between myocardial sickness in anterior, posterior and fundus with latency interval.

Abstract
PURPOSE Helicobacter pylori is the etiological agent in duodenal and peptic ulcers. The growing problem of antibiotic resistance by the organism demands the search for novel compounds, especially from natural sources. This study was conducted to evaluate the effect of Camellia sinensis extracts on the urease enzyme that is a major colonization factor for H. pylori. METHODS Minimum inhibitory concentrations of nonfermented and semifermented C. sinensis methanol: water extracts were assessed by broth dilution method. Examination of the urease function was performed by Mc Laren method, and urease production was detected on 12% SDS polyacrylamide gel electrophoresis from whole cell and membrane bound proteins. RESULTS Both extracts had inhibitory effects against H. pylori and urease production. At a concentration of 2.5 mg/ml of nonfermented extract and 3.5 mg/ml of semifermented extract the production of Ure A and Ure B subunits of the urease enzyme were inhibited completely. A concentration of 4 mg/ml of nonfermented and 5.5 mg/ml of semifermented extract were bactericidal for H. pylori. CONCLUSIONS C. sinensis extracts, especially the nonfermented, could reduce H. pylori population and inhibit urease production at lower concentrations. The superior effect of nonfermented extract is due to its rich polyphenolic compounds and catechin contents.
