Prevalence of gestational diabetes mellitus and its maternal and fetal outcomes

We hereby report the results of a prospective cohort study where we compared the association of various demographic factors and gestational diabetes mellitus (GDM), determined the prevalence of GDM and its maternal and fetal outcomes

Benign papillary cystadenofibroma of fallopian tube presenting as posterior fornix cyst: case report

Benign papillary cystadenofibroma of fallopian tube is very rare tumor of female genital tract. Usually asymptomatic and incidental finding. Worldwide literature only 18 cases were found. On account of its rarity and best of our knowledge, is the first case of benign papillary cystadenofiboma presented as posterior fornix cyst, so we are presenting this case. We report a rare case of benign papillary cystadenofibroma of fallopian tube in a 30-years old female P3L3 presenting with abdominal pain. On examination abdomen was soft, per vaginally mobile non-tender cystic mass of 5×4 cm was noted. Laparotomy was planned. Intraoperatively 5x4 cm cyst arising from serosal surface of left fallopian tube near fimbrial end noted with bilateral ovaries normal. Left fimbrial cystectomy with salpingectomy was done with sparing both ovaries. Histopathology suggestive of benign papillary cystadenofibroma of fallopian tube. Patient had uneventful recovery in follow up period. Benign papillary cystadenofibroma of fallopian tube is rare tumor found incidentally. Tumor seems to have benign course only cystectomy is required for treatment

Effect of transition metal substitution on elastoplastic properties of LiMn2O4 spinel

LiMn[subscript 2]O[subscript 4] (LMO) derivatives partially substituted with transition metals (e.g., Ni) have received attention for their higher energy density achieved at higher charge voltage than pure LMO, and may be attractive cathode candidates for emerging all solid state batteries. Accurate mechanical properties of these high voltage spinels are required for prediction of electrode and electrolyte fracture that may compromise battery lifetime and performance. Here, we quantified the Young’s elastic modulus E and hardness H for LMO, LiMn[subscript 1.5]Ni[subscript 0.5]O[subscript 4] (LMNO), and LiMn[subscript 1.5]Ni[subscript 0.42]Fe[subscript 0.08]O[subscript 4] (LMNFO) spinel microparticles via instrumented grid nanoindentation. Elastic modulus E and hardness H increased by more than 40% (up to 145 and 11 GPa, respectively) as a result of Ni or Ni/Fe substitution; such substitution also reduces the lattice parameter and increases the oxidization state of Mn. These results demonstrate how changes in transition metal occupancy can significantly affect the mechanical properties of LMO spinel, and provide critical parameters for designing against fracture in all solid state batteries.United States.
