We introduce a framework for end-to-end integrative modeling of 3D single-cell multi-channel fluorescent image data of diverse subcellular structures. We employ stacked conditional β-variational autoencoders to first learn a latent representation of cell morphology, and then learn a latent representation of subcellular structure localization which is conditioned on the learned cell morphology. Our model is flexible and can be trained on images of arbitrary subcellular structures and at varying degrees of sparsity and reconstruction fidelity.

Although some cell types may be defined anatomically or by physiological function, a rigorous definition of cell state remains elusive. Here, we develop a quantitative, imaging-based platform for the systematic and automated classification of subcellular organization in single cells. We use this platform to quantify subcellular organization and gene expression in >30,000 individual human induced pluripotent stem cell-derived cardiomyocytes, producing a publicly available dataset that describes the population distributions of local and global sarcomere organization, mRNA abundance, and correlations between these traits.

Urban pest control insecticides-specifically fipronil and its 4 major degradates (fipronil sulfone, sulfide, desulfinyl, and amide), as well as imidacloprid-were monitored during drought conditions in 8 San Francisco Bay (San Francisco, CA, USA) wastewater treatment plants (WWTPs). In influent and effluent, ubiquitous detections were obtained in units of ng/L for fipronil (13-88 ng/L), fipronil sulfone (1-28 ng/L), fipronil sulfide (1-5 ng/L), and imidacloprid (58-306 ng/L). Partitioning was also investigated; in influent, 100% of imidacloprid and 62 ± 9% of total fiproles (fipronil and degradates) were present in the dissolved state, with the balance being bound to filter-removable particulates.

Objective: To provide a more comprehensive view than previously available of US physician preparedness for public health emergencies, this study examined physicians' assessments of their preparedness, training, participation in institutional activities, information practices, and experiences with patient education. Four kinds of public health emergencies were considered: natural disasters, major airborne infections, major foodborne illness outbreaks, and chemical, biological, radiological, nuclear, or explosives (CBRNE) incidents.

Methods: Between October 19, 2011, and January 11, 2012, researchers conducted a national poll among 1603 practicing physicians in a range of specialties in hospital and nonhospital settings.

This issue of the Journal of Dental Education is a celebration of its seventy-fifth year as the premier journal for intellectual discourse on all aspects of dental education. It is a well-deserved celebration because it is broader than the journal itself. It is a celebration of excellence, success, and, above all, improved oral health for the American people and beyond.

Dental schools are hard pressed to find the resources to adequately fund their mission of education, research, and service. Over the years, schools have tried to make up for the loss in public funds by increasing student tuition, increasing enrollment, and reducing the growth in faculty and staff salaries and program costs. Unfortunately, these strategies have not solved the financial problems.

Following a wave of dental school closures from 1986 to 2001 and a perceived shortage of dentists, three new dental schools were established between 1997 and 2003, and eight more are in various stages of planning and development to open over the next decade. Conditions are moving rapidly, and several institutions have stated intentions to open new dental schools since this analysis. This article presents a supply-side analysis of the impact of the new schools on the effective dentist to population ratio, taking into account changes in graduation rates, retirement rate, population growth, productivity, and gender ratio of the profession.

Background: Market power among dental insurance carriers is a carrier's ability to reimburse dentists at rates below what would exist in more competitive areas. Competition among carriers for dentists' participation in their networks protects dentists from highly discounted fees. The authors examined the extent to which dental insurance carriers facing less competition increase fee discounts.

Objectives: Congress created the State Children's Health Insurance Program (SCHIP) in 1997 as an expansion of the Medicaid program to provide health insurance to children whose family income is above the Medicaid eligibility standards-generally up to 200% of the federal poverty level (FPL). This article examines changes in the utilization of dental services during a period of increasing public funding of dental services.

Methods: Public dental expenditure estimates came from the Centers for Medicare & Medicaid Services (CMS), and a breakdown of these expenditures by patient age and income level was based on the Medical Expenditure Panel Survey (MEPS).

Introduction: In this article, we describe recent trends in the age of patients receiving orthodontic services and look at how expenditures for these services are related to patient age and income level.

Methods: These findings are based on 3 national health expenditure surveys sponsored by the Agency for Healthcare Policy and Research conducted in 1987, 1996, and 2004.

Results: Recent increases in the number of patients receiving orthodontic services were largely due to an increase in the overall population.

This article examines the impact of financial trends in state-supported dental schools on full-time clinical faculty; the diversity of dental students and their career choices; investments in physical facilities; and the place of dentistry in research universities. The findings of our study are the following: the number of students per full-time clinical faculty member increased; the three schools with the lowest revenue increases lost a third of their full-time clinical faculty; more students are from wealthier families; most schools are not able to adequately invest in their physical plant; and more than half of schools have substantial NIH-funded research programs. If current trends continue, the term "crisis" will describe the situation faced by most dental schools.

Statement Of Problem: Dentists and patients are regularly confronted by a difficult treatment question: should a tooth be saved through root canal treatment and restoration (RCT), be extracted without any tooth replacement, be replaced with a fixed partial denture (FPD) or an implant-supported single crown (ISC)?

Purpose: The purpose of this systematic review was to compare the outcomes, benefits, and harms of endodontic care and restoration compared to extraction and placement of ISCs, FPDs, or extraction without tooth replacement.

Material And Methods: Searches performed in MEDLINE, Cochrane, and EMBASE databases were enriched by hand searches, citation mining, and expert recommendation. Evidence tables were developed following quality and inclusion criteria assessment.

Objective: This article estimates the financial impact of a ban on amalgam restorations for selected population groups: the entire population, children, and children and women of childbearing age.

Methods: Using claim and enrollment data from Delta Dental of Michigan, Ohio, and Indiana and the American Dental Association Survey of Dental Services Rendered, we estimated the per capita use and annual rate of change in amalgam restorations for each age, gender, and socioeconomic subgroup. We used population projections to obtain national estimates of amalgam use, and the dental component of the Consumer Price Index to estimate the annual rate of change in fees.
