Background: Acute graft-versus-host disease (aGVHD) is the most frequent and severe complication after allogeneic hematopoietic stem cell transplantation (HSCT). Objective: To determine if a history of prior infection in the allogeneic HSTC recipient is a risk factor to develop aGVHD. Methods: A retrospective cohort study based on data collected from the Department of Hematopoietic Stem Cell Transplantation at the Instituto Nacional de Pediatría (INP) from January 1998 to December 2016 was performed to identify if prior infection was a predictive risk factor for aGVHD. Results: 27 patients developed aGVHD (36.4%). Median time to aGVHD presentation was 82 days (9 to 273 days). Most patients developed grade III aGVHD. Following the multivariate analysis peripheral blood > bone marrow (OR 12.3;p 8.3 × 106/kg (OR 7.1;p = 0.05), peripheral blood (OR: 11.4;p < 0.001), infection 3 months prior to allogeneic transplant (OR: 4.5;p < 0.03) and CMV infection in the recipient (OR: 4.68;p Conclusions: Either bacterial infection or CMV infection in the recipient was significant risk factor within the aGVHD recipients;it is important to consider these factors for patients that are going to receive an allogeneic HSCT.

Flooding an extremely alkaline(pH 10.6) saline soil of the former Lake Texcoco to reduce salinity will affect the soil carbon(C)and nitrogen(N) dynamics.A laboratory incubation experiment was done to investigate how decreasing soil salt content affected dynamics of C and N in an extremely alkaline saline *** soil with electrical conductivity(EC) of 59.2 dS m^(-1) was packed in columns,and then flooded with tap water,drained freely and conditioned aerobically at 50%water holding capacity for a *** process of flooding-drainage-conditioning was repeated eight *** original soil and the soil that had undergone one,two,four and eight flooding-drainage-conditioning cycles were amended with 1000 mg glucose-^(14)C kg^(-1) soil and 200 mg NH_4^+-N kg^(-1)soil,and then incubated for 28 *** CO_2 emissions,soil microbial biomass,and soil ammonium(NE_4^+),nitrite(NO_2^-) and nitrate(NO_3^-) were monitored in the aerobic incubation of 28 *** soil EC decreased from 59.2 to 1.0 dS m^(_1) after eight floodings,and soil pH decreased from 10.6 to *** the added ^(14)C-labelled glucose,only 8%was mineralized in the original soil,while 24%in the soil flooded eight times during the 28-d *** priming effect was on average 278 mg C kg^(-1) soil after the 28-d *** microbial biomass C(mean 66 mg C kg^(-1) soil) did not change with flooding times in the unamended soil,and increased 1.4 times in the glucose-NH_4^+-amended *** immobilization and NO_2^- concentration in the aerobically incubated soil decreased with increasing flooding times,while NO_3^- concentration *** was found that flooding the Texcoco soil decreased the EC sharply,increased mineralization of glucose,stimulated nitrification,and reduced immobilization of inorganic N,but did not affect soil microbial biomass C.

Isothermal flashless die forging process of Ti - alloy structural air - frame part with varying thickness rib has been modelled in this *** results of present study show that a upside - down trapezoid rib would be formed and buckling would occure as blank is reduced,if the thickness of billet is maller than or equal to the thickness of rib. During modelling process of structural air frame part with E type cross - section rib, the saddle or lap would be formed finally at the middle of transverse rib between ribs with increase in *** metal is allowed to flow out at confluence of longitudinal and transverse rib, the lop defect would be eliminated,, but a pipe cavity is obvious on corresponding loca- tion of blank. of defect formation depends on distance of metal flow ,friction,temperature homoge- neity of the blank and complexity of the part.

Objective: To determine the response to tamoxifen in a woman with hypogonadotropic hypogonadism induced by hyperprolactinemia resistant to dopamine agonist drugs. Design: Case report. Setting: Academic fertility center. Patient(s): A young woman with persistent amenorrhea, symptomatic hypogonadotropic hypogonadism, and hyperprolactinemia. Intervention(s): Tamoxifen was administered in addition to bromocriptine. Main Outcome Measure(s): Measurements of follicle-stimulating hormone, estradiol, prolactin, and progesterone. Result(s): Recovery of gonadal-hypothalamic-pituitary axis. Conclusion(s): Tamoxifen can revert the effects of chronic hypogonadotropic hypogonadism induced by hyperprolactinemia resistant to dopamine agonists.
