Published: August 2010

In this paper, we propose generalized sampling approaches for measuring a multi-dimensional object using a compact compound-eye imaging system called thin observation module by bound optics (TOMBO). This paper shows the proposed system model, physical examples, and simulations to verify TOMBO imaging using generalized sampling. In the system, an object is modulated and multiplied by a weight distribution with physical coding, and the coded optical signal is integrated on to a detector array. A numerical estimation algorithm employing a sparsity constraint is used for object reconstruction.

Background: The Highlands of Papua New Guinea are non-endemic for malaria compared to the rest of the country. This study aimed to explore the local transmission of malaria in the Highlands through a cross-sectional school survey coupled with reactive case detection.

Methods: Between July and November 2019, 5575 schoolchildren and 1048 household members were screened for malaria using Rapid Diagnostic Tests, subsequently validated by light microscopy.

Aim: The study was designed to evaluate molecular alterations, relevant to the prognosis and personalized therapy of salivary gland cancers (SGCs).

Materials And Methods: DNA was extracted from archival tissue of 40 patients with various SGCs subtypes. A targeted next-generation sequencing (NGS) panel was used for the identification of small-scale mutations, focal and chromosomal arm-level copy number changes.

Background: The coronavirus disease (COVID-19) pandemic led to the implementation of social distancing laws in the UK. This had several negative consequences on health, wellbeing and social functioning within the general population. Military veterans may have had unique experiences of social isolation during this time.

Background: This in vitro study evaluated the efficacy of professional and home-use fluoride regimens for protecting irradiated enamel, undergoing pH cycling resembling xerostomia.

Methods: Sixty human premolar teeth were irradiated with a total dose of 70 Gy and subsequently sectioned into 3 × 3 cm enamel slabs. These slabs were randomly distributed into five groups (n = 12 per group): professional-use groups received fluoride varnish either weekly (FV1) or biweekly (FV2); home-use groups applied 5000 ppm (FT5) or 1450 ppm (FT) fluoride toothpaste; and a control group (control) received no treatment.

Association between type of health insurance and dental visits among Ecuadorian older population: evidence from a cross-sectional study.

BMC Public Health

January 2025

Facultad de Ciencias de la Salud Eugenio Espejo, Universidad UTE, Centro de Investigación en Salud Pública y Epidemiología Clínica (CISPEC), Quito, Ecuador.

Background: Dental services are often overlooked within healthcare systems, despite their critical role in overall health. Socioeconomic barriers and disparities in insurance coverage frequently limit access to oral care, particularly among vulnerable populations like older adults.

Objective: To examine the impact of different health insurance types on the frequency of dental consultations among Ecuadorian senior citizens, aiming to highlight gaps in access to care.
