Background: This article reviews our community cancer center's experience treating head and neck cancer primarily with accelerated fractionation intensity-modulated radiation therapy (IMRT), with or without concurrent chemotherapy, focusing on acute toxicity and efficacy.
Methods: Fifty-two patients treated with IMRT at the Penrose Cancer Center between 2002 and 2007 constitute the cohort. The majority (75%) received an accelerated, altered fractionation regimen, typically concomitant boost to 7200 cGy. Concurrent chemotherapy was delivered to 32 (62%). The median follow-up was 24 months.
Results: The 2-year actuarial rates of local control, regional control, and distant metastasis-free survival were 100%, 91%, and 94%, respectively. Relapse-free survival and overall survival at 2 years were 89% and 91%, respectively. Overall, 32 of 52 patients (62%) experienced at least 1 type of grade 3 or 4 acute toxicity.
Conclusion: Accelerated fractionation IMRT, with or without chemotherapy, can be given safely and effectively in a community cancer center setting.

The influence of algal organic matter (AOM) on the settling performance of algal flocs remains poorly understood. To address this, we employed fractionation techniques based on molecular weight to isolate different AOM fractions and analyzed their effects on floc structure and settling performance. This involved comparing the concentrations, compositions, potentials, and functional groups of organic matter before and after coagulation-sedimentation.

Purpose: Randomized trials have demonstrated similar local tumor control in patients treated with accelerated partial-breast irradiation (APBI) compared with whole-breast irradiation. However, the optimal APBI dose for maximizing tumor control and minimizing toxicity is uncertain.
Methods And Materials: We enrolled patients ≥18 years of age with grade 1 or 2 ductal carcinoma in situ or stage I invasive breast cancer and resection margins ≥2 mm between 2003 and 2011 to a sequential dose-escalation trial using 3-dimensional conformal external beam APBI giving twice daily 4 Gy fractions with total doses of 32 Gy, 36 Gy, and 40 Gy.

Background: Heart failure with preserved ejection fraction (HFpEF) is linked to prolonged endoplasmic reticulum (ER) stress. P21-activated kinase 2 (Pak2) facilitates a protective ER stress response. This study explores the mechanism and role of Pak2 in HFpEF pathology.

Purpose: To use imaging data from stereotactic MR-guided online adaptive radiotherapy (SMART) of ultracentral lung tumors (ULT) for development of a safe non-adaptive approach towards stereotactic body radiotherapy (SBRT) of ULT.
Patients And Methods: Analysis is based on 19 patients with ULT who received SMART (10 × 5.0-5.

Objective: Abaloparatide (ABL) is a synthetic parathyroid hormone-related protein analog developed as an anabolic drug to treat osteoporosis. ABL increases bone mineral density (BMD) of the long bones and spine; however, the influence of ABL on alveolar bone regeneration remains unknown. This study assessed the effects of systemic ABL administration on tooth extraction socket healing and dental implant osseointegration in a preclinical rodent model.
