Sexual Health Education Experiences and Recommendations from the Perspective of LGBTQ+ Youth.

Despite the well-known benefits of comprehensive sexual health education, the majority of school sexual health education curricula in the United States (U.S.) is non-comprehensive and excludes LGBTQ+ students.

Retrieving difficult aspirated pen caps by balloon catheter with short working-length flexible endoscopy and noninvasive ventilation support in intensive care unit.

Objectives: Aspirated pen cap (APC) is a clinical challenging issue in children because of the difficulty in both making diagnosis and performing extraction. In case of failed retrieval by rigid endoscopy (RE), more invasive surgical approaches are recommended. The objective of this study is to introduce a new retrieval technique of APC by using laser and balloon catheter (BC) guided with flexible endoscopy (FE) and supported by a novel non-invasive ventilation (NIV) in the intensive care unit (ICU) setting.

Identification of a multipotent self-renewing stromal progenitor population during mammalian kidney organogenesis.

The mammalian kidney is a complex organ consisting of multiple cell types. We previously showed that the Six2-expressing cap mesenchyme is a multipotent self-renewing progenitor population for the main body of the nephron, the basic functional unit of the kidney. However, the cellular mechanisms establishing stromal tissues are less clear.

Serotonin as an integrator of leech behavior and muscle mechanical performance.

The obliquely striated muscle in the leech body wall has a broad functional repertoire; it provides power for both locomotion and suction feeding. It also operates over an unusually high strain range, undergoing up to threefold changes in length. Serotonin (5-HT) may support this functional flexibility, integrating behavior and biomechanics.

TRAIL inactivates the mitotic checkpoint and potentiates death induced by microtubule-targeting agents in human cancer cells.

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has attracted interest as an anticancer treatment, when used in conjunction with standard chemotherapy. We investigated the mechanistic basis for combining low-dose TRAIL with microtubule-targeting agents that invoke the mitotic checkpoint. Treatment of T98G and HCT116 cells with nocodazole alone resulted in a robust mitotic block with initially little cell death; low levels of cell death were also seen with TRAIL alone at 10 ng/mL final concentration.

Quantification of amplified quenching for conjugated polymer microsphere systems.

A series of nonaggregating carboxylate-functionalized poly(phenylene ethynylene)s (PPEs) have been synthesized for immobilization via electrostatic adsorption onto Eu3+-polystyrene microspheres with a mean diameter of 0.2 microm. This system is shown to constitute a ratiometric system that measures fluorescence quenching with high fidelity.

Late cardiac mortality and morbidity in early-stage breast cancer patients after breast-conservation treatment.

Purpose: Several studies have reported increased cardiac mortality related to the use of left-sided breast or chest-wall irradiation. This study was undertaken as a comprehensive examination of the long-term cardiac mortality and morbidity after breast irradiation using contemporary irradiation techniques.

Methods: The medical records of 961 consecutive patients presenting between 1977 and 1994 with stage I or II breast cancer treated with breast conservation treatment were reviewed.
