Mixed ammonium-transition metal salts with formula of （NH4）xMyHzPMo12O40 （M = Ni^2＋, Co^2＋ or Fe ^3＋） denoted as MPMo12 have been investigated for the oxidation of propane, with molecular oxygen, at temperature range between 380 ℃ and 420 ℃ after in-situ pre-treatment performed at two heating rate of 5 or 9℃/min. They were characterized by BET method, XRD, UV-Vis and IR techniques. The catalysts were found to be active in the propane oxidation and selective to propene or acrolein, in particular for samples pre-treated with the heating rate of 9℃/min. FePMo12 was found to be a more active catalyst for propene （17.2% yield） with minimal over deep oxidation （0.3% yield in COx）.

AIM: To evaluate the incidence and severity of ocular graft versus host disease(o GVHD) in patients who underwent allogeneic stem cell transplant(SCT) in King Abdul-Aziz Medical City, Saudi ***: This is a retrospective cohort study conducted in King Abdul Aziz Medical City on patients who underwent allogeneic hematopoietic cell transplant(allo-HCT) from 2010 to 2017. The ocular examination findings including visual acuity, meibomian gland dysfunction, corneal and conjunctival staining with severity, corneal scarring, tear film meniscus and breakup time, anterior and posterior segment examination findings, intraocular pressure, treatment given, punctual plugs used or not, and follow up response were ***: The five years cumulative incidence of o GVHD among post-transplant patients was 56.98%(95%CI 38.6%-71.7%). The potential risk factors assessed for developing ocular manifestation were age, gender, donor’s age, donor gender mismatch CD3 and CD34 infusion, while none of the correlates were identified as statistically significant risk factors of developing ocular manifestation. However, the incidence was statistically significantly different betweenpatients diagnosed with acute myelocytic leukemia and acute lymphocytic leukemia(P=0.038). The mean latent period to develop ocular symptoms was 20.5 mo. All patients had variable degree of dry eyes. None of the patients developed any posterior segment ***: The incidence of o GVHD is low in King Abdul-Aziz Medical City. This can be attributed to the preconditioning and immunosuppressive regime.

Using a bidentate ligand, a Schiff base 4-（{[（Z）-（2-hydroxyphenyl）methyldene]amino}methyl）cyclohexanecarboxylic acid, complex I（ML2, where M = Cd（Ⅱ）） was synthesized and characterized by IR spectroscopy and X-ray crystallography. It crystallizes in monoclinic system, space group C2/c, M_r = 685.04, 0.34 mm × 0.26 mm × 0.14 mm, a = 54.050（3）, b = 6.1220（3）, c = 9.5081（5） A, β = 90.229（2）°, Z = 4, C_（30） H_（40） CdN_2 O_9 and V = 3146.2（3） A^3. Complex I was screened for its bactericidal activity against four bacterial strains Chromohalobactersalexigens, Chromohalobacterisraelensis, Halomonashalofila and Halomonassalina and fungicidal activity against Aspergillusnigerand Aspergillusflavus. Antimicrobial activity results showed that the synthesized complex displayed good anti-fungal activity against two fungal strains. It was found to be inactive against four different bacterial strains analyzed and was negative for bactericidal effect.
