Dental Service Organization affiliation: Understanding key aspects of State Dental Practice Act compliance.

Dental Service Organizations (DSOs) are an increasingly visible and available practice option for new dental graduates. While guidance has been published to help dental students make informed decisions when considering a DSO affiliation, they have not focused on the complexities of assessing compliance with controlling state laws. Accordingly, this Perspectives article provides a concise summary of the common components of state regulatory provisions across the United States to support an understanding of the corporate practice of dentistry and compliance considerations.

Mobilization of As, Fe, and Mn from Contaminated Sediment in Aerobic and Anaerobic Conditions: Chemical or Microbiological Triggers?

We integrated aqueous chemistry, spectroscopy, and microbiology techniques to identify chemical and microbial processes affecting the release of arsenic (As), iron (Fe), and manganese (Mn) from contaminated sediments exposed to aerobic and anaerobic conditions. The sediments were collected from Cheyenne River Sioux Tribal lands in South Dakota, which has dealt with mining legacy for several decades. The range of concentrations of total As measured from contaminated sediments was 96 to 259 mg kg, which co-occurs with Fe (21 000-22 005 mg kg) and Mn (682-703 mg kg).

Arsenic Accumulation in Hydroponically Grown (Little Bluestem) Amended with Root-Colonizing Endophytes.

We integrated microscopy, spectroscopy, culturing and molecular biology, and aqueous chemistry techniques to evaluate arsenic (As) accumulation in hydroponically grown inoculated with endophytic fungi. grows in historically contaminated sediment in the Cheyenne River Watershed and was used for laboratory experiments with As(V) ranging from 0 to 2.5 mg L at circumneutral pH.

What guidance does HIPAA offer to providers considering familial risk notification and cascade genetic testing?

Background: It is unclear how the Health Insurance Portability and Accountability Act (HIPAA) should be interpreted in the context of sharing of genomic information between family members.

Methods: The authors analyzed the HIPAA Privacy Rule, reviewed the literature and constructed a clinical scenario to inform how HIPAA can be interpreted for multiple forms of patient- and provider-mediated genetic risk notification.

Results: Under HIPAA, healthcare providers can lawfully notify relatives to recommend genetic risk assessment using multiple approaches, including supporting the patient telling their own relatives, contacting relatives directly with the patient's authorization, or contacting a relative's provider directly.

Emerging investigator series: entrapment of uranium-phosphorus nanocrystals inside root cells of plants from a mine waste site.

We investigated the mechanisms of uranium (U) uptake by Tamarix (salt cedars) growing along the Rio Paguate, which flows throughout the Jackpile mine near Pueblo de Laguna, New Mexico. Tamarix were selected for this study due to the detection of U in the roots and shoots of field collected plants (0.6-58.
