Objective: To check the effectiveness of tourniquet in the prevention of haemorrhage during myomectomies at the University hospital of brazzaville. Patients and methods: Analytical cross-sectional study, conducted at the University hospital of brazzaville from June 1, 2014 to June 30, 2016. Recruitment was performed by randomly matching each case of myomectomy performed using a tourniquet with two cases of myomectomy without tourniquet (50 cases vs 100 witnesses). We used as a tourniquet, the surgical glove knotted and tightened sufficiently at the level of the isthmus of the uterus to temporarily occlude the uterine arteries to ensure haemostasis lasting no more than one hour. Results: The mean age of the patients was similar in both groups (36, 1 ± 2.2 years vs 36.2 ± 1.9 years, P > 0.05). Menorrhagia was the most common indication of myomectomy in both groups (76% vs. 78% P > 0.05). The mean haemoglobin level of the patients before the myomectomies was 9.03 ± 1.10 g/dl vs 9, 75 ± 1.29 g/dl;P > 0.05. Intraoperative uterine features were similar in size (18 weeks gestation, 14 - 24) and number of myomas (5 vs 4, P > 0.05) in both groups. Polymyomectomy was more common in both groups (76% vs 73%, P > 0.05). blood loss was reduced in the tourniquet group (90.5 ± 4.6 ml vs 200.4 ± 5.6 ml;P 0.05), as well as the use of blood transfusion (8% vs 50%, P 0.05). Use of the number of sutures was reduced in the group with tourniquet (3 ± 0.2 vs 6 ± 0.2 P 0.05). The duration of the procedure was shorter in the group with tourniquet (51.5 ± 4 min vs 83 ± 7 min, P 0.05). Postoperative mean haemoglobin of patients was no different between the two groups (9.4 ± 0.7 g/dl vs 9.2 ± 0.5, P > 0.05). The overall cost of management was reduced in the group with tourniquet (190,680 ± 1450 F CFA vs 256,800 ± 2350 FCFA;P 0.05). Conclusion: The use of tourniquet during myomectomies significantly reduces blood loss and the use of blood transfusion. We also obtain the notorious reduction in th

The integrated luminosities of data samples collected in the bESⅢ experiment in 2016-2017 at centerof-mass energies between 4.19 and 4.28 GeV are measured with a precision better than 1% by analyzing large-angle bhabha scattering *** integrated luminosities of old datasets collected in 2010-2014 are updated by considering corrections related to detector performance,offsetting the effect of newly discovered readout errors in the electromagnetic calorimeter,which can haphazardly occur.

This study details the nature and magnitude of the genetic effects associated with various quantitative characters (morphological and hydric relations) measured in maize seedlings during the osmotic phase of saline stress (100 mM NaCl). Three lines with differential behavior in salt stress: SC2 (tolerant), AFE (susceptible) and LP3 (moderately tolerant) were used to obtain contrasting crosses (SC2 × AFE) and (SC2 × LP3). An analysis of six generational means (P1, P2, F1, F2, bC1 and bC2) was applied for each cross. First a scaling test was applied and then a three and six-parameter genetic models were used to estimate various genetic components. In none of the traits studied there was evidence of adequacy to the three parameter model, which indicates important epistatic effects in genetic expression. The dominant genetic effects were greater than the additive ones for all the characters evaluated. LG showed positive and significant differences for [h] in both crosses, indicating the presence of hybrid vigor and its possible use in the improvement. Low value of [d] and high of [h] both significant in SC2 × AFE, indicates existence of genes dispersion between the parental lines. While, for the cross SC2 × LP3, the low and significant value of [d] and not significant value of [h], indicate greater genetic similarity. In the SC2 × LP3 cross, the negative interaction [l] confirms ambidirectional dominance, while for SC2 × LP3 the positive sign indicates directional dominance. The analysis of tolerance to salinity in the osmotic phase showed a complex polygenic inheritance for the traits used, determined by simple and interaction effects of different magnitudes and significance according to the cross considered.

Confined thin film melt polymerization (CTFMP) of naphthalene chloride/hydroquinone (NCMQ, 1/1, molar)mixtures at polymerization temperatures (T_p) below ca. 300℃ resulted in relatively thick, elongated crystals. Polymerizationof NC/hQ above 300℃ between glass yielded well-formed lamellar crystals ca. 100 A thick. Phase Ⅰ and Ⅱ [001] EDpatterns were obtained for all T_p, the relative amount of phase Ⅰ increasing with T_p. Polymerization of naphthalenedicarboxylic acid/hydroquinione diacetate 1/1 mixtures at high T_p also yielded lamellar crystals that "curled up" off of thesubstrate. When the high temperature CTFMP polymerization was conducted between mica, aggregates of lamellae on-edgedeveloped but epitaxial growth did not occur. Epitaxial growth of lamellae between mica could be obtained, however, byconfined thin film solution polymerization, with both of the latter samples yielding apparently related ED patterns from adifferent unit cell than phase Ⅰ or Ⅱ. Fiber patterns, obtained from sheared samples, indicated considerably greater crystaldisorder than in the nascent crystals. Refinement of the phase Ⅰ unit cell parameters, based on the [001] and [01 1] EDpatterns, with modeling based on Cerius^2, suggests a monoclinic phase Ⅰ unit cell with a = 7.76, b = 5.71, c = 14.99 A, α = γ= 90°, β= 99.7°, ρ = 1.47 g/cm^3, space group P12_1/al.

An experiment was conducted to determine how an E. coil challenge and dietary clays affect the intestinal barrier of pigs. Two groups of 32 pigs （initial bW： 6.9 ± 1.0 kg） were distributed in a 2 x 4 factorial arrangement of a randomized complete block design （2 challenge treatments： sham or E. coil, and 4 dietary treatments： control, 0.3% smectite A, 0.3% smectite b and 0.3% zeolite）, with 8 replicates total. Diarrhea score, growth performance, goblet cell size and number, bacterial translocation from intestinal lumen to lymph nodes, intestinal morphology, and relative amounts of sulfo and sialo mucins were measured. The E. coli challenge reduced performance, increased goblet cell size and number in the ileum, increased bacterial translocation from the intestinal lumen to the lymph nodes, and increased ileal crypt depth. One of the clays （smectite A） tended to increase goblet cell size in ileum, which may indicate enhanced protection. In conclusion, E. coli infection degrades intestinal barrier integrity but smectite A may enhance it.
