OBJECTIVES To quantify and compare peri-acetabular bone mineral density (BMD) between a monoblock acetabular component using a metal-on-metal (MoM) bearing and a modular titanium shell with a polyethylene (PE) insert. The secondary outcome was to measure patient-reported clinical function. METHODS A total of 50 patients (25 per group) were randomised to MoM or metal-on-polyethlene (MoP). Ther...

Most of the mitochondrial outer membrane (MOM) proteins contain helical transmembrane domains. Some of the single-span proteins and all known multiple-span proteins are inserted into the membrane in a pathway that depends on the MOM protein Mitochondrial Import 1 (Mim1). So far it has been unknown whether additional proteins are required for this process. Here, we describe the identification an...

The expression of the DNA modification gene (mom) of bacteriophage Mu requires the cellular deoxyadenosine methylase (dam) and a transactivation factor from the phage. By hypothesis, the transcription of mom is activated by methylation of three GATC sequences upstream from the mom gene. We have introduced small deletions at a fourth GATC site located about 140 base pairs downstream from the pri...

The American Academy of Pediatrics recommends that extremely preterm infants receive mother's own milk (MOM) when available or pasteurized donor breast milk (DBM) when MOM is unavailable. The goal of this study was to determine whether DBM could be inoculated with MOM from mothers of preterm infants to restore the live microbiota (RM). Culture dependent and culture independent methods were used...

A method SYS 2toMoM to map systolic systems onto the MoM ( m apo riented m achine) is introduced in this paper. This mapping method is needed to derive a methodology of MoM application development support from the theory of systolic array synthesis. The MoM is a flexible non-von-Neumann computer principle having been developed at Kaiserslautern. MoM "programming" uses combinational code (for pa...

BACKGROUND Adverse reactions to metal debris (ARMD) have resulted in the high short-term failure rates observed with metal-on-metal hip replacements. ARMD has recently been reported in non-metal-on-metal total hip replacements (non-MoM THRs) in a number of small cohort studies. However the true magnitude of this complication in non-MoM THRs remains unknown. We used a nationwide database to dete...

Many mitochondrial outer membrane (MOM) proteins have a transmembrane domain near the C terminus and an N-terminal cytosolic moiety. It is not clear how these tail-anchored (TA) proteins posttranslationally select their target, but C-terminal charged residues play an important role. To investigate how discrimination between MOM and endoplasmic reticulum (ER) occurs, we used mammalian cytochrome...
