Severe preeclampsia is a challenging issue facing both intensivist and anesthetic team carrying both maternal and fetal morbidity and mortality. Termination of pregnancy after blood pressure control is the golden key in management. Cerebral complications due to diffuse cerebral vasospasm are most common and serious. Intrathecal midazolam with its gamma amino butyric action may antidote glutamate mediated sympathetic surge and decreasing cerebral vasospasm. Temporal view transcranial Doppler imaging maternal middle cerebral artery is used to examine blood flow indices namely pulsatility index and resistive index. One hundred ladies with severe preeclampsia scheduled for urgent caesarian section were recruited in 2 groups, both received 10 mg bupivacaine 0.5%, Midazolam group received 1 mg midazolam and the other group received 0.2 ml sterile saline 0.9% NaCl. All vascular indices were significantly better in midazolam group, less ICU stay.

In this paper, we compare different nanoclay-PEG composites and the influence of the input parameters especially the percentage of PEG and the clay size. Because of the facility of material elaboration, dried state with grinding, we adopted a complete experiments plan to obtain a maximum of robustness of the responses. For each sample, we made an XRD analysis to see if we obtain the intercalation of the PEG 6000 (Polyethylene Glycol 6000) within the clay sheets. The characterization adopted consists on the measurement of the shrinking of some cylinders we made, the liquidity and plasticity limits according to the Casagrande protocol used in geotechnical clays characterizations. We utilize also the methylen blue protocol to estimate the variation of the specific surface of ionic exchange of the clay sheets according to the PEG 6000 percentage and the clay sizes. SEM microscopy permits to visualize some of the phases detected by the XRD analysis. The TEM microscopy permits also to see the amorphous phases created by the grinding protocol which affects significantly the specific surface and the shrinking of the new materials. For each section, we made some conclusions with interpretation in order to integrate these results in civil engineering, classical/artisanal material construction and geotechnical fields.

Aim: The responses of 10 patients with long-standing, symptomatic, intractable drug-refractory histories of irritable bowel syndrome with diarrhea (IBS-D) and with abdominal pain, gas/bloating and distention, termed IBS undefined (IBS-U), were evaluated when administering a medical food product containing serum-derived bovine immunoglobulin/protein isolate (SBI). Methods: Patients in this case series were chosen based on their lack of satisfactory response to a variety of drugs, including antidiarrheal and antispasmodic medications, serotonin 5-HT3 receptor antagonists, selective serotonin re-uptake inhibitors (SSRIs), proton pump inhibitors (PPIs), antibiotics, and antidepressive drugs. Patients met Rome III criteria and were administered 5 g/day of SBI as standard-of-care nutritional support. A scale of 0% - 25%, 25% - 50%, 50% - 75%, 75% - 100% response to SBI was used for patient-reported improvement in overall IBS symptoms following administration for one month. Exact methods for calculating confidence intervals and p-values were used to assess complete management of symptoms and response to therapy. Adverse events were also monitored for this nutritional product. Results: The onset of gastrointestinal (GI) symptom reduction utilizing nutritional management with SBI occurred within an average time of 2-4 weeks with improved or near complete management in all 10 patients who were refractory to previous drug therapies by 4 weeks. When prompted, patients reported significant IBS symptom improvement which averaged between 50% - 100% (p = 0.002) with an average for complete management in all patients of 69%. No side effects were reported after SBI administration even when taken for up to 28 weeks. Conclusion: Based on the safety profile and reported outcomes in this case report, SBI should be considered as a nutritional option for management in IBS-D and IBS-U.

The main objective of the present work is to investigate the properties of plasmas created by injecting a thermalized beam of antiprotons in two types of media. The first is hydrogen, deuterium, or tritium atoms localized in palladium crystals. The second medium is composed of protons, deuterons, or tritons localized in a magnetic cavity. Particularly, it is demonstrated that huge amounts of energy are released in both cases which could be used as fuels for space shuttle engines. A novel mathematical scheme is employed to calculate the energy yields in real space at different incident energies of the antiprotons.

The main difficulty in direct current resistivity(DCR) interpretation is the lithologic unit identification and layer boundary detection especially in sedimentary environments,. The problem of layer boundary detection caused by the presence of near surface heterogeneity and high conductive layer, it can lead to misinterpretation. Further, the conventional interpretation methods of DCR data still have a degree of the exact-data non-uniqueness problem. In this study, a combined use of conventional and nonconventional inversion methods is presented for reconstructing the paleolandscape at ancient Bubastis archaeological site, East Nile Delta, Egypt. Genetic alghorithms inversion is applied for DCR soundings interpretation by considering the borehole data and conventional inversion results. Based on such inverted DCR data, the interpreted data was presented in 3 D models to give regional picture of the subsurface layer distribution of the area.

The main purpose of this work is to shed light on the possibility of producing huge amount of energy based on the construction matter-antimatter plasma in a molecular crystal. It is assumed that two beams of isothermal hydrogen and antihydrogen are injected into a palladium crystal leading to a plasma state composed of particles and antiparticles. The collapse of this state releases a huge amount of energy which can be used as fuel for space shuttles. Thus, the novel system of isothermal pressure interaction enhances the energy power carried out by the quantum ion acoustic soliton (QIAS). In addition to the energy power released from the particle-antiparticle annihilation. The probability of merging the energy from these two cases is available at certain condition. The released energy may be a significant step in solving the energy scape of Tokomak to produce fusion energy. The study starting from the one-dimensional quantum hydrodynamic model (in which the term of electron-positron and proton-antiproton for hydrogen-antihydrogen is included), a Korteweg de Vries equation (kdv) is derived, the QIAS energy experiences and the annihilation energy power are calculated. It is found that the total energy of QIAS and the energy resulting from hydrogen-antihydrogen annihilation are important step towards the establishment of a cold fusion power station.

The aim of this study is to estimate the variations in curie point depth, geothermal gradient and heat flux from the frequency analysis of magnetic data in order to evaluate the geothermal potential of the Kaladi locality and its surroundings. For this purpose, the magnetic field map was first reduced to equator (RTE). The centroid method was used to divide the RTE grid into a set of 40 blocks. The spectral analysis applied to each block allowed determining the depth to top (Zt), center (Z0) and bottom (Zb also called curie point depth or CPD) of the magnetic sources. Knowing the different CPD, the geothermal gradient associated with each block was calculated. The heat flow was then calculated from the geothermal gradient associated with the anomaly block considered. From the set of values obtained for each block, maps of geothermal gradient and heat flow variations were established. Analysis of these maps shows that the sectors that could be favourable for geothermal exploration are the north of Kaladi and the Goro-Bembara corridor, because they show variations in the geothermal gradient and heat flow between 0.4 and 0.8℃/m and between 1.2 and 2 mW/m2 respectively. In addition, the superposition of the different hot springs highlighted in previous studies with areas of high geothermal gradient and heat flow values supports this analysis. The proposed models can be used as background documents for any geothermal exploration project in the study area.

The influences of medicinal plants Juniperus Phoenicea (Araar), Hyphaene thebaica (Doum), An-astatica hierochuntica (Kafta) and Cleome droserifolia (Sammo) as antidiabetic agents were investigated using female pregnant albino rats. Female rats were injected with 60 mg/kg b.w. alloxan to induce diabe-tes. Diabetic rats treated orally with the methanol extracts of tested plants till the 19 day of gestation. The present studies include the frequencies of chro-mosomal aberrations and nucleic acid system of liver in the female pregnant rats and their embryos. The results showed that injection of alloxan caused highly significant increase in chromosomal aberrations as well as in blood glucose levels as a result of diabetes in pregnant females. It also caused a high incidence of chromosomal deviation in embryos and decreased the liver soluble protein contents of female rats and their embryos. These effects in alloxanized animals were treated and improved by ingestion of the methanol extracts of the tested plants (Araar, Doum, Kafta and Somma) in which under their treatments, the inceased level of blood glu-cose of diabetic rats was deceased. Ingestion with the plants methanolic extracts improved and normalized the effects of diabetes in nucleic acids values of liver tissues. These were accompanied with nucleases (RNAase and DNAase) activities. The inhibited ac-tivities of both DNA ase and RNA ase of pregnant rats and their embryos were stimulated and read-justed around the normal values. Also administration of the plants methanol extracts decreased the per-centage of chromosomal aberrations in the female rats and embryos. It is concluded that there are some biochemical dynamics which might occur in the metabo-lism of glucose, nucleic acids and proteins in order to prevent or to reduce the oxidative stress of diabetes by flavonoides treatment.
