Rorc restrains the potency of ST2+ regulatory T cells in ameliorating intestinal graft-versus-host disease

Soluble stimulation-2 (ST2) is increased during graft-versus-host disease (GVHD), while Tregs that express ST2 prevent GVHD through unknown mechanisms. Transplantation of Foxp3- T cells and Tregs that were collected and sorted from different Foxp3 reporter mice indicated that in mice that developed GVHD, ST2+ Tregs were thymus derived and predominantly localized to the intestine. ST2-/- Treg transplantation was associated with reduced total intestinal Treg frequency and activation. ST2-/- versus WT intestinal Treg transcriptomes showed decreased Treg functional markers and, reciprocally, increased Rorc expression. Rorc-/- T cells transplantation enhanced the frequency and function of intestinal ST2+ Tregs and reduced GVHD through decreased gut-infiltrating soluble ST2-producing type 1 and increased IL-4/IL-10-producing type 2 T cells. Cotransfer of ST2+ Tregs sorted from Rorc-/- mice with WT CD25-depleted T cells decreased GVHD severity and mortality, increased intestinal ST2+KLRG1+ Tregs, and decreased type 1 T cells after transplantation, indicating an intrinsic mechanism. Ex vivo IL-33-stimulated Tregs (TregIL-33) expressed higher amphiregulin and displayed better immunosuppression, and adoptive transfer prevented GVHD better than control Tregs or TregIL-33 cultured with IL-23/IL-17. Amphiregulin blockade by neutralizing antibody in vivo abolished the protective effect of TregIL-33. Our data show that inverse expression of ST2 and RORγt in intestinal Tregs determines GVHD and that TregIL-33 has potential as a cellular therapy avenue for preventing GVHD

Prevention of stillbirths: impact of a two-stage screening for vasa previa

Objectives: To examine the feasibility and effectiveness of a two-stage ultrasound screening strategy for detection of vasa previa and estimate the potential impact of screening on prevention of stillbirth. Methods: This was a retrospective examination of data from prospective screening for vasa previa in singleton pregnancies undertaken at the Fetal Medicine Centre at Medway Maritime Hospital, UK between 2012 and 2018. Women booked for prenatal care and delivery in our hospital had routine ultrasound examinations at 11-13 and 20-22 weeks’ gestation. Those with velamentous cord insertion at the inferior part of the placenta at the first-trimester scan and those with low-lying placenta at the second-trimester scan were classified as high-risk for vasa previa and had transvaginal sonography specifically searching for vasa previa at the time of the 20-22 weeks scan. The management and outcome of cases with suspected vasa previa is described. We excluded cases of miscarriage or termination at <24 weeks’ gestation. Results: The study population of 26,830 singleton pregnancies, included 21 (0.08% or 1 in 1,278) with vasa previa. In all cases of vasa previa the diagnosis was made at the 20-22 weeks scan and confirmed by gross and histological examination of the placenta postnatally. At the 11-13 weeks scan the cord insertion was classified as central in 25,071 (93.4%) cases, marginal in 1,680 (6.3%), and velamentous in 79 (0.3%). In 16 (76.2%) of the 21 cases of vasa previa, the cord insertion at the first-trimester scan was classified as velamentous at the inferior part of the placenta, in 2 (9.5%) as marginal and in 3 (14.3%) as central. The 21 cases of vasa previa were managed on an outpatient basis with serial scans for measurement of cervical length and elective cesarean section at 34 weeks’ gestation; all babies were liveborn but there was one neonatal death. In the study population there were 83 stillbirths and postnatal examination showed no evidence of vasa previa in any of the cases. On the assumption that if we had not diagnosed prenatally all 21 cases of vasa previa in our population half of these cases would have resulted in stillbirth, then the potential impact of screening is prevention of 9.6% (10/104) of stillbirths. Conclusion: A two-stage strategy of screening for vasa previa can be incorporated into routine clinical practice and such strategy could potentially reduce the rate of stillbirth

Replantation of Nine Fingers in a Patient: A case report

Amputation of multiple fingers of both hands is a rare and serious injury. We report a case of a 41-year-old male patient who presented to Khoula Hospital, Muscat, Oman, in 2015 with the amputation of nine fingers due to a workplace injury. With two teams working in tandem, all the amputated fingers were re-attached. A total of seven fingers survived and the patient regained reasonable functionality of his hands. To the best of the authors’ knowledge, this is the first case of several finger amputations in Oman.Keywords: Fingers; Traumatic Amputation; Crush Injuries; Replantation; Case Report; Oman

Hydrogen Energy Storage: New Techno-Economic Emergence Solution Analysis

International audienceThe integration of various renewable energy sources as well as the liberalization of electricity markets are established facts in modern electrical power systems. The increased share of renewable sources within power systems intensifies the supply variability and intermittency. Therefore, energy storage is deemed as one of the solutions for stabilizing the supply of electricity to maintain generation-demand balance and to guarantee uninterrupted supply of energy to users. In the context of sustainable development and energy resources depletion, the question of the growth of renewable energy electricity production is highly linked to the ability to propose new and adapted energy storage solutions. The purpose of this multidisciplinary paper is to highlight the new hydrogen production and storage technology, its efficiency and the impact of the policy context on its development. A comprehensive techno/socio/economic study of long term hydrogen based storage systems in electrical networks is addressed. The European policy concerning the different energy storage systems and hydrogen production is explicitly discussed. The state of the art of the techno-economic features of the hydrogen production and storage is introduced. Using Matlab-Simulink for a power system of rated 70 kW generator, the excess produced hydrogen during high generation periods or low demand can be sold either directly to the grid owners or as filled hydrogen bottles. The affordable use of Hydrogen-based technologies for long term electricity storage is verified

Performance of Some Soybean Genotypes (Glycine max L.) to Germination and Seedling Characters as Affected by Planting Dates and Phosphorus Fertilization

To investigate the performance of some sunflower genotypes to phosphorus fertilizer rates and planting dates to germination characters and seedling parameters. A laboratory experiment accompanied in seed lab during April and May 2017.The experiments included six sowing dates at 1th May, 15th May and 31th May, three soybean cultivars namely Crawford, Giza 22 and Giza 111 and three rates of phosphorus fertilizer viz. 0, 37.2 and 74.4 kg P2O5/ha.The tallest shoot, great percentages of germination, the lowermostpercentagesof dead seedand the highestcoefficient of velocitypercentage from sown on mid-May. In addition, the lowest days of germination time was produced from sown on first May. Whereas, the tallest root, the highest weight of fresh shoot and root as well as shoot dry weight from sown on end-May.The results clearly revealed that the highest percentage of germination, soot length and root length obtained from sown cv. Giza 111. The uppermostenergy of germination, shoot and root dry weight were recorded from sown Giza 22 cultivar. In addition, sown Crawford cultivar produced the highestdead seedpercentage and the lowest mean germination time.The results indicated that the lowest mean germination time and maximum percentage of coefficient of velocity, tallest shoot and root, weight of fresh shoot, shoot and dry root were obtained fromfertilizationof phosphate at the rate of31 kgP2O5/fed. It summarized that seed Giza 111 cultivar recorded the best in seed viability when sown on first May and fertilized with phosphorus fertilizer at the rate of 74.4 kg P2O5/ha

Behaviors of Some Soybean Cultivars (Glycine max L.) Yield to Planting Dates and Different Phosphorus Fertilizer Rates

Soybean production components such as planting date, cultivars and phosphorus fertilizer rates affected soybean yield. Two field experiments conducted in extensive field at El-Gahrbia district, Egypt during 2015 and 2016 seasons. The goal of this research was aimed to investigate the influence of sowing date at 1th May, 15th May and 31th May and three phosphorus fertilization rates, i.e. 0, 37.2 and 74.4 kg P2O5/ha on the performance of three soybean (Glycine max (L.) Merrl) cultivars i.e. Crawford, Giza 22 and Giza 111 on growth, yield and seed quality. The tallest plants, the thick stem, highest branches number/plant, pods number/plant, seed number/pod, weight of 1000 seed and seed yield/ha were recorded from sown early on first May in the both seasons. The tallest plants, the thick stems and highest number of branches/plant were recorded from sown Crawford cultivar. Whereas maximum number of pods/plant and number of seed/pod were found from sown Giza 111 cultivar in the both seasons. Increasing phosphorous fertilizer rates significantly increased all studied cultivars of seed yield and yield components. Tallest plant, the thick stem, the highest branches number/plant, pods number/plant, seed number/pod, weight of1000 seed and seed yield/ha were produced from phosphorous fertilizer at a rate of 74.4 kg P2O5/ha in the first and second seasons, respectively

Antifungal synergic activity of essential olive oil and alcoholic turmeric extracts against isolates from the dried grapes raisins

Fungi are responsible for a wide variety of harm to humans, including food spoilage and infections. Using chemicals to restrict fungal development or infections has negative repercussions, such as human health dangers from the chemical applications and rising antifungal-drug resistance, so this study aimed to use medicinal plants and their extracts as an alternative method to restrict fungal growth. Ten isolates of the genus Aspergillus were identified from the fruits of dried grapes (raisins) of all kinds (Iraqi black raisins, Iranian yellow raisins, and brown raisins) at the species level using three – differential media: Czapek Yeast Extract Agar( CYA), Malt Extract Agar( MEA), and 25% Glycerol nitrate agar (G25N) incubated in 5, 25 and 37 ºC. Aspergillus niger was the most common isolated species. The number of A. niger isolates reached seven from all types of dried grapes, while A. flavus recorded three isolates from black raisins and brown raisins. Aspergillus Flavus Parasiticus Agar (AFPA) was used to detect the ability of A. flavus isolates to produce aflatoxin at 25-30 ºC for one week. Alcoholic extract of turmeric showed a significant inhibitory effect on the colony diameter of both A. flavus and A. niger isolated from the fruit of Iraqi black raisins with an inhibition rate of 86.6% and 68.8 %, respectively, at 4 mg/ ml concentration. The mixture of turmeric and essential olive oil gave a distinct inhibitory effect, reaching a 100% inhibition rate from the lowest to highest concentration for both A. niger and A. flavus
