The minichromosome maintenance complex (MCM) represents the replicative DNA helicase both in eukaryotes and archaea. Here, we describe the solution structure of the C-terminal domains of the archaeal MCMs of Sulfolobus solfataricus (Sso) and Methanothermobacter thermautotrophicus (Mth). Those domains consist of a structurally conserved truncated winged helix (WH) domain lacking the two typical ...

Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest forms of cancer and is very difficult to treat with conventional chemotherapeutic regimens. Gemcitabine and 5-fluorouracil are used in the management of PDAC and act by indirectly blocking replicative forks. However, these drugs are not highly effective at suppressing disease progression, indicating a need for the development of in...

Cre-loxP technology for conditional gene inactivation is a powerful tool in cardiovascular research. Induction of gene inactivation can be carried out by per oral or intraperitoneal tamoxifen administration. Unintended transient cardiomyopathy following tamoxifen administration for gene inactivation has recently been reported. We aimed to develop a protocol for tamoxifen-induced gene inactivati...

BACKGROUND AND OBJECTIVES There is ongoing growth of elderly populations with ESRD in Western Europe and North America. In our center, we offer an alternative care pathway of 'maximum conservative management' (MCM) to patients who elect not to start dialysis, often because of a heavy burden of comorbid illness and advanced age. The objective of our study was to compare clinical outcomes for pat...

Introduction BioSense is a national human health surveillance system for disease detection, monitoring, and situation awareness through near realtime access to existing electronic healthcare encounter information, including information from hospital emergency departments (EDs). MCM include antibiotics, antivirals, antidotes, antitoxins, vaccinations, nuclide-binding agents, and other medication...

In S. cerevisiae, the chromatin structure of DNA replication origins changes as cells become competent for DNA replication, suggesting that G1 phase-specific association of replication factors with origin DNA regulates entry into S phase. We demonstrate that ORC, Cdc45p, and MCM proteins are components of prereplication complexes (pre-RC). The MCM-origin association is dependent upon ORC and Cd...

Composites of hydroxyapatite (HaP) and highly ordered large pore mesoporous silica molecular sieves such as, Al-SBA-15 and Al-MCM-41 (denoted as SBA-15 and MCM-41, respectively) were developed, characterized by XRD, BET, FTIR, HRTEM and NMR-MAS, and applied to fluoride retention from contaminated water. The proposed procedure by a new route to prepare the HaP/SBA-15 and HaP/MCM-41, composites g...

Purified motoneurons from chick, cultured on polycationic substrata treated with myotube-conditioned (MCM), respond by rapidly extending neurites. When MCM, partially purified by salt precipitation and ion-exchange chromatography, was fractionated on Sepharose CL-4B, the peak of neurite outgrowth-promoting activity (NOPA) corresponded to a peak of laminin (LA) immunoreactivity. Fractions from t...

Products motivated by performance-driven and/or density-driven goals often use Multi-Chip Module (MCM) technology, even though it still faces several challenging problems that need to be resolved before it becomes a widely adopted technology. Among its most challenging problems is achieving acceptable MCM assembly yields while meeting quality requirements. This problem can be significantly redu...
