Application of CAD-CAM 3D Technology in Designing a Molar Distalization Device with Skeletal Anchorage: A Case Report.

Mandibular molar distalization is a complex orthodontic movement due to anatomic and biomechanical limitations. The opportunity to use a custom-made appliance with skeletal anchorage should be an advantageous alternative to traditional solutions: multiple extractions, interproximal reductions, vestibular inclination of incisal group. : A 14-year-old female patient with Class II malocclusion and ectopic upper and lower canines was treated in the lower arch with a custom-made appliance anchored on a mini-screw in the right buccal-shelf where the ectopy and crowding was severe.

Correlates of health-related quality of life in African Americans diagnosed with cancer: a review of survivorship studies and the Detroit research on cancer survivors cohort.

Advances in cancer screening and treatment have improved survival after a diagnosis of cancer. As the number of cancer survivors as well as their overall life-expectancy increases, investigations of health-related quality of life (HRQOL) are critical in understanding the factors that promote the optimal experience over the course of survivorship. However, there is a dearth of information on determinants of HRQOL for African American cancer survivors as the vast majority of cohorts have been conducted predominantly among non-Hispanic Whites.

Release dynamics of nanodiamonds created by laser-driven shock-compression of polyethylene terephthalate.

Laser-driven dynamic compression experiments of plastic materials have found surprisingly fast formation of nanodiamonds (ND) via X-ray probing. This mechanism is relevant for planetary models, but could also open efficient synthesis routes for tailored NDs. We investigate the release mechanics of compressed NDs by molecular dynamics simulation of the isotropic expansion of finite size diamond from different P-T states.

Direct observation of strong momentum-dependent electron-phonon coupling in a metal.

Phonon scattering in metals is one of the most fundamental processes in materials science. However, understanding such processes has remained challenging and requires detailed information on interactions between phonons and electrons. We use an ultrafast electron diffuse scattering technique to resolve the nonequilibrium phonon dynamics in femtosecond-laser-excited tungsten in both time and momentum.

Oxygen-ozone autohemotherapy in breast cancer patients suffering from fatigue and musculoskeletal pain upon aromatase inhibitors treatment: a case-series study.

Objective: In patients with breast cancer and positive hormone receptors, aromatase inhibitors are effective in reducing the risk of recurrences and are active in progressing the disease in this setting. On the other hand, fatigue and painful musculoskeletal side effects can significantly reduce treatment compliance. With no further treatment options to control these symptoms, non-pharmaceutical interventions, such as oxygen-ozone therapy, may play a role in managing rheumatologic symptomatology inasmuch.

Cytokine profiles in COVID-19 patients undergoing adjunct ozone therapy: some comments.

Cytokine profile and antioxidants status in the moderate and severe COVID-19 patients: a trial of ozone therapy impact as a medicinal supplement. Inflammopharmacology.

Housing instability and psychological distress in African American cancer survivors: findings from the Detroit Research on Cancer Survivors study.

Purpose: As health care systems seek to screen for and address housing instability in patient populations, robust evidence linking unstable housing to patient-reported outcomes is needed. Housing instability may increase psychological distress in cancer survivors, potentially more so among African American cancer survivors who are also likely to experience disproportionate burden of housing instability. The purpose of this analysis was to estimate associations between housing instability and psychological distress in African Americans diagnosed with cancer.

The Ancient Olive Trees ( L.) of the Maltese Islands: A Rich and Unexplored Patrimony to Enhance Oliviculture.

A prospecting campaign in the Maltese Islands has ensured the survival of several ancient olive trees ( L.), genetically distant from known cultivars. Most of these plants were abandoned or partially cultivated.

The impact of preexisting comorbidities on receipt of cancer therapy among women with Stage I-III breast cancer in the Detroit Research on Cancer Survivors cohort.

Purpose: Pre-existing comorbidities play an important role in choice of cancer treatment. We retrospectively evaluated the relationship between pre-existing comorbidities and receipt of local and systemic therapy in a cohort of Black women with Stage I-III breast cancer.

Methods: The study population for analysis included 1169 women with Stage I-III disease enrolled in the Detroit Research on Cancer Survivors (ROCS) cohort.

A hidden Markov model for continuous longitudinal data with missing responses and dropout.

We propose a hidden Markov model for multivariate continuous longitudinal responses with covariates that accounts for three different types of missing pattern: (I) partially missing outcomes at a given time occasion, (II) completely missing outcomes at a given time occasion (intermittent pattern), and (III) dropout before the end of the period of observation (monotone pattern). The missing-at-random (MAR) assumption is formulated to deal with the first two types of missingness, while to account for the informative dropout, we rely on an extra absorbing state. Estimation of the model parameters is based on the maximum likelihood method that is implemented by an expectation-maximization (EM) algorithm relying on suitable recursions.
