The role of Typha spp. on water loss and public health has been uncertained and relatively poorly reported in Hadejia Nguru wetlands. This study investigated the extent to which Typha spp. contributed to evapotranspirative water loss and the level at which it provides suitable habitat for mosquito breeding. A comparative analysis between Typha swamp and open water was made to determine the evapotranspiration water loss and mosquito larva load accounted for by Typha swamp in the wetland. Maximum and minimum temperatures were measured and recorded daily for the months of January, March and June in 2013. Blaney-Criddle equation was used to estimate the evapotranspiration from Typha swamp (Site A) while piche evaporimeter was used to measure direct evaporation from the adjacent open water (Site B). Water samples were collected in Sites A and B using 100 ml beaker at random and the number of mosquito larvae in the sample was counted. T test was used to evaluate differences in water loss and larva load between open water and Typha swamp in the wetland. The findings revealed that there was no significant difference in water loss at p pha swamp and open water in the wetland. However, the Typha swamp was found to harbor more mosquito larvae than the open water at p public health risk.

AIM To investigate the incidence of spontaneous bacterial peritonitis(SBp) in pre-transplant patients and its effect on post transplant mortality and graft failure. METHODS We conducted a retrospective cohort study of patient records from the organ procurement and transplant network data set. patients were identified by the presence of SBp pre-transplant. Univariate post-transplant survival models were constructed using the Kaplan-Meier technique and multivariate models were constructed using the Cox proportional hazards model. Variables that affected post-transplant graft survival were identified in the SBp population. RESULTS Forty-seven thousand eight hundred and eighty patient records were included in the analysis for both groups, and 1966(4.11%) patients were identified in the data set as having pre-transplant SBp. patients that had pre-transplant SBp had higher rates of graft loss from recurrent hepatitis C virus(HCV)(3.6% vs 2.0%, p p = 0.02), primary non-function(4.3% vs 3.0%, p nd chronic rejection(1.1% vs 0.7%, p = 0.04). Kaplan-Meier survival analysis showed a statistically significant difference in all-cause survival in patients with a history of SBp vs those without(p pretransplant history of SBp was independently predictiveof mortality due to recurrent HCV(HR = 1.11, 95%CI: 1.02-1.21, p patients prior to the advent of directing acting anti-viral agents had a higher incidence of pre-transplant SBp than other patients on the liver transplant wait list. SBp history pre-transplant resulted in a higher rate of graft loss due to recurrent HCV infection and chronic rejection.

The interactions of La（ Ⅲ ）, pr（ Ⅲ ）, nd（ Ⅲ ）, Sm（ Ⅲ ）, Eu（Ⅲ）, Gd（ Ⅲ ）, Dy（ Ⅲ ）, and Yb（ Ⅲ ） with cytosine, 5-bromocytosine, 5-azacytosine and 5-flurocytosine as primary ligands （L） and guanine （A） as secondary ligand for both binary （ 1 ： 1 ） as well as ternary （ 1 ： 1 ： 1 ） systems were investigated by potentiometric equilibrium measurements at 25, 35 and 45 ℃ in aqueous solution （ionic strength, μ = 0.1 mol·dm^-3 NaNO3）. The stability constants of the binary （ 1 ： 1 ） and ternary （ 1 ： 1 ： 1 ） metal-ligand complexes follow the following order La 〈 pr 〈 nd 〈 Sm 〈 Eu 〉 Gd 〈 Dy 〉 Yb. Results also indicate that the ternary lanthanide complexes of La（Ⅲ）, pr（Ⅲ）, nd（Ⅲ）, Sm（Ⅲ）, Eu（Ⅲ）, Gd（Ⅲ）, Dy（Ⅲ）, and Yb（ Ⅲ ） are more stable than corresponding binary lanthanide complexes. The enthalpy （△Hf^o） and entropy （△Sf^o） changes for the formation of binary and ternary complexes were calculated from temperature coefficient data. The △△Sf^o values are positive for all the metal ligand systems. The negative △△Hf^o values indicate the extra stability of the ternary complexes by the exothermic enthalpy changes （△△Sf^o = △TSf^o - △BSf^o and △△Hf^o = △THf^o - △BHf^o where △TSf^o, △THf^o and △BSf^o, △BHf^o are the entropy and enthalpy values associated with the ternary and binary complexes, respectively）. It was also proposed that the guanine is bonded to metal ions through N1/C6 = O and N7 whereas cytosine and its derivatives are bonded through N3 atoms in ternary complexes.
