We report the effect of shape anisotropy and material properties on the directed assembly of binary suspensions composed of magnetizable ellipsoids. In a Monte Carlo simulation, we implement the ellipsoid-dipole model to calculate the pairwise dipolar interaction energy as a function of position and orientation. The analysis explores dilute suspensions of paramagnetic and diamagnetic ellipsoids with different aspect ratios in a superparamagnetic medium.

Infant faces readily capture adult attention and elicit enhanced neural processing, likely due to their importance evolutionarily in facilitating bonds with caregivers. Facial malformations have been shown to impact early infant-caregiver interactions negatively. However, it remains unclear how such facial malformations may impact early visual processing.

Emerging antimicrobial drug resistance is increasing the complexity involved in treating critical conditions such as bacterial induced sepsis. Methods for diagnosing specific drug resistance tend to be rapid or sensitive, but not both. Detection methods like sequence-specific single-molecule analysis could address this concern if they could be adapted to work on smaller targets similar to those produced in traditional clinical situations.

Microbial resistance to currently available antibiotics poses a great threat in the global fight against infections. An important step in determining bacterial antibiotic resistance can be selective DNA sequence capture and fluorescence labeling. In this paper, we demonstrate the fabrication of simple, robust, inexpensive microfluidic devices for DNA capture and fluorescence detection of a model antibiotic resistance gene sequence.

Purpose: To explore whether privacy restrictions developed to protect patients have complicated research within a 15-year surveillance study conducted with US cancer registries.

Methods: Data from enrolling 27 cancer registries over a 10-year period were examined to describe the amount of time needed to obtain study approval. We also analyzed the proportion of patients that completed a research interview out of the total reported by the registries and examined factors thought to influence this measure.

Objectives: To assess the impact of HAART use on AIDS-defining Kaposi's sarcoma and non-Hodgkin lymphoma (NHL) among adults with AIDS.

Design: Registry linkage study.

Methods: Adults diagnosed with AIDS from 1990 to 2000 in the San Francisco AIDS case registry were matched with cancer cases diagnosed from 1985 to 2002 in the California Cancer Registry.

Background: A major challenge in cancer chemotherapy has been developing safe and clinically efficacious chemotherapeutic agents. With its low toxicity profile, curcumin (diferuloylmethane), a naturally occurring flavinoid derived from the rhizome of Curcuma longa, has great promise. In vitro and in vivo preclinical studies have shown its inhibitory anticancer, antioxidant, anti-inflammatory, antiproliferative, and proapoptotic activities.

Objective: This study describes breast cancer stage at diagnosis among California women receiving mammograms through a state-administered screening program in comparison to other California women.

Method: Linked data from California-administered screening programs and the California Cancer Registry were used to identify participants diagnosed with breast cancer between 1994 and 2000. Logistic regression was used to compare the adjusted likelihood of late stage disease among program participants (categorized into four subgroups based on the timing and frequency of mammograms) to non-participants in California diagnosed during the same time period.
