MOF assistance synthesis of nanoporous double-shelled CuCoO hollow spheres for hybrid supercapacitors.

Design of complex hollow nanostructures of two or more transition metal oxides seems to be necessary to answer the demand for novel energy storage electrodes owning outstanding performance for advanced developments of modern electronics. Herein, we develop a metal-organic frameworks (MOFs) assistance self-templated method for the synthesis of double-shell CuCoO hollow spheres as battery-type electrode material with a large surface area of 93 m g. This electrode material reveals excellent electrochemical performance with an ultrahigh specific capacity of 701 C g at 2 A g.

Associations between maternal anthropometric characteristics and infant birth weight in Iranian population.

Objective: To examine the (1) normal ranges of anthropometric and insulin resistance/sensitivity indices (homeostatic model assessment for insulin resistance, homeostatic model assessment for insulin sensitivity, and quantitative insulin sensitivity check index) for Iranian pregnant women and their newborns and (2) associations between maternal anthropometric and metabolic values and infants' birth weights among Iranian women.

Methods: Anthropometric and metabolic values of 163 singleton non-diabetic pregnant women in Tehran, Iran (2014) were collected before and during pregnancy and at delivery. Linear regression, multivariable regression, and Student t tests were used to evaluate correlations between birth weight and maternal variables.

The prevalence of group B streptococcus colonization in Iranian pregnant women and its subsequent outcome.

Background: Group B streptococcus colonization in pregnant women usually has no symptoms, but it is one of the major factors of newborn infection in developed countries. In Iran, there is a little information about the prevalence of maternal colonization and newborns infected by group B streptococcus. In order to find the necessary information to create a protocol for prevention and treatment of group B streptococcus infection in newborns, we conducted a study of its prevalence among Iranian pregnant women and its vertical transmission to their newborns.

Neonatal atypical hemolytic uremic syndrome may cause prenatal asphyxia.

Microthrombi formation and hemolytic anemia are signs of hemolytic-uremic syndrome (HUS) that result from platelet consumption and red blood cell (RBC) destruction due to vascular damage. HUS manifests as a triad of signs: micro-angiopathic hemolytic anemia, thrombocytopenia, and uremia. Prenatal asphyxia (PA) also leads to renal insufficiency and vascular damage.

Intrauterine diagnosis and management of fetal goitrous hypothyroidism: a report of an Iranian family with three consecutive pregnancies complicated by fetal goiter.

The diagnosis and treatment of hypothyroidism during the fetal period may decrease perinatal morbidity and are believed to be important to optimize growth and intellectual development. Herewith a case report of fetal goitrous hypothyroidism is presented in a euthyroid mother, detected at 34 weeks' gestation by ultrasonography, and treated with intra-amniotic levothyroxine injections. The mother had two previous consecutive pregnancies (13 and 8 years ago), also complicated by the occurrence of fetal goiter, resulting in tracheal compression, asphyxia, and early neonatal death in the first and in an emergency cesarean section delivery, because of fetal malpresentation, in the second neonate affected by congenital hypothyroidism (CH).
