and comorbidity-matched controls, with trending or significant improvements in delirium, radiographs, and biomarkers, and no significant acute toxicity. Low-dose, whole-lung radiation for patients with COVID-19-related pneumonia appears safe and may be an effective immunomodulatory treatment. Larger prospective randomized trials are needed to define the efficacy of LD-RT for COVID-19.

A prospective cohort of predominantly elderly hospitalized patients with COVID-19-related pneumonia were recovered to room air quicker than age- and comorbidity-matched controls, with trending or significant improvements in delirium, radiographs, and biomarkers, and no significant acute toxicity. Low-dose, whole-lung radiation for patients with COVID-19-related pneumonia appears safe and may be an effective immunomodulatory treatment. Larger prospective randomized trials are needed to define the efficacy of LD-RT for COVID-19.

To characterize the early changes in echocardiographically derived measures of cardiac function with contemporary radiation therapy (RT) in breast cancer and to determine the associations with radiation dose-volume metrics, including mean heart dose (MHD).

In a prospective longitudinal cohort study of 86 patients with breast cancer treated with photon or proton thoracic RT, clinical and echocardiographic data were assessed at 3 time points within 4 weeks before RT initiation (T0), within 3 days before 6 weeks after the end of RT (T1), and 5 to 9 months after RT completion (T2). Associations between MHD and echocardiographically derived measures of cardiac function were assessed using generalized estimating equations to define the acute (T0 to T1) and subacute (T0 to T2) changes in cardiac function.

The median estimates of MHD were 139 cGy (interquartile range, 99-249 cGy). In evaluating the acute changes in left ventricular ejection fraction (LVEF) from T0 to T1, and accounting for the time from RT, ageto determine whether these early changes are associated with the development of overt cardiac disease.

We report long-term outcomes from our phase 1 dose-escalation study to determine the maximum tolerated dose of single-fraction liver SABR pooled with our subsequent single institutional experience with patients treated postprotocol at the highest dose level (40 Gy) established from the phase 1 study.

Patients with liver metastases from solid tumors located outside of the central liver zone were treated with single-fraction SABR on a phase 1 dose escalation trial. At least 700 cc of normal liver had to receive <9.1 Gy. Seven patients with 10 liver metastases received the initial prescription dose of 35 Gy, and dose was then escalated to 40 Gy for 7 more patients with 7 liver metastases. An additional 19 postprotocol patients with 22 liver metastases were treated to 40 Gy in a single fraction. Patients were followed for toxicity and underwent serial imaging to assess local control.

Median imaging follow-up for the combined cohort (n = 33, 39 lesions) was 25.9 months; 38.9 months for protocol patients afraction SABR doses of 40 Gy confirmed our earlier results.

Microbial biofilm formation, a quorum sensing (QS) regulated process, is one of the major causes of nosocomial and chronic infections, foodborne diseases, and associated deaths. Various approaches have been used to eradicate the menace of biofilm. Ethnomedicinal plants as potent antibiofilm agents are gaining a lot of interest in an era where the drug resistance is increasing and the availability of potent antibiotics is no longer promised. In this context, the methanol extract of Cuphea carthagenensis (CCMD), an ethno-medicinal and culinary herb, was evaluated as an antibiofilm and anti-QS agent against Pseudomonas aeruginosa.

The aim of the study is to evaluate the antibiofilm and anti-QS activity of an ethnomedicinal plant against a strong biofilm forming microorganism, P. aeruginosa.

Antibiofilm activity of CCMD was demonstrated at different concentrations by Tissue Culture Plate, Test Tube method and other microscopic techniques. The effect of CCMD on QS and QS-related virulence factors viz. Pyocyathe extract.

This work is the first to demonstrate that C. carthagenensis can attenuate biofilm formation and QS-mediated virulence factors of P. aeruginosa. Further investigation is required to use this ethnomedicinal plant (CCMD) as an important source of antibiofilm agents.

Curcuma longa L is traditionally used as an anti-inflammatory remedy in Chinese traditional medicine. Curcuma oil (CO), a lipophilic fraction from Curcuma longa L. has been reported to have anti-proliferative, anti-inflammatory and anti-oxidant activities. However, CO has never been investigated for its possible therapeutic effects on benign prostatic hyperplasia (BPH).

The study is thus to determine the therapeutic effects of curcuma oil on BPH and also the possible mechanism (s) of action.

A BPH-1 cell line and Sprague Dawley (SD) rats were used to establish BPH models in vitro and in vivo, respectively. selleck products Rats were treated by CO (2.4, 7.2mg/kg/i.g.) and finasteride (5mg/kg/i.g.), respectively. Histological changes were examined by hematoxylin and eosin (H&E) staining. Protein expression was analyzed for 5α-reductase (5AR), dihydrotestosterone (DHT), interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α by ELISA. Ki-67, Caspase-8,-9 and -3 expressions were evaluated via immunohistochemistry (Ixpression of phosphorylated p65 and consequently reduced the inflammatory responses and cell survival in prostatic tissues, leading to the inhibition of BPH development in rats.

Curcuma oil is very effective for ameliorating BPH in rats. The underlying mechanisms involve in reduced inflammatory responses and cell survival through suppression of the NF-κB signaling pathway by CO in prostatic tissues.
