D A Gardner-Dale, I M Bradley, J S Guest
Microalgal treatment systems could advance nutrient recovery from wastewater by achieving effluent nitrogen (N) and phosphorus (P) levels below the current limit of technology, but their successful implementation requires an understanding of how design decisions influence nutrient uptake over daily (i.e., diel) cycles. This work demonstrates the ability to influence microalgal N:P recovery ratio via solids residence time (SRT) while maintaining complete nutrient removal across day/night cycles through carbon storage and mobilization...

INTRODUCTION AND OBJECTIVES: The extended-release formulation of tacrolimus (ERT) allows once-daily dosage, thus simplifying the immunosuppressive regimen. This study aimed to describe the safety and efficacy of the de novo and early use of ERT in heart transplantation. METHODS: This was an observational, retrospective, multicenter study comparing the safety and efficacy of the de novo use of ERT (ERT group [n=94]), standard-release tacrolimus (SRT group [n=42]) and early conversion (EC) from SRT to ERT (EC group [n=44])...

OBJECTIVE: The RTOG 9601 and GETUG-AFU 16 randomized controlled trials demonstrated that the addition of androgen deprivation therapy (ADT) to salvage radiation therapy (SRT) improves progression-free and, for RTOG 9601, overall survival. We examined national trends in the use of ADT with SRT. MATERIALS AND METHODS: Of the 484,009 patients in the National Cancer Database from 2004 to 2012 with localized or locally advanced prostate cancer treated with radical prostatectomy (RP), 4,200 men received SRT (≥6mo after surgery)...

It has been shown that patients with electric acoustic stimulation (EAS) perform better in noisy environments than patients with a cochlear implant (CI). One reason for this could be the preserved access to acoustic low-frequency cues including the fundamental frequency (F0). Therefore, our primary aim was to investigate whether users of EAS experience a release from masking with increasing F0 difference between target talker and masking talker. The study comprised 29 patients and consisted of three groups of subjects: EAS users, CI users and normal-hearing listeners (NH)...

BACKGROUND: Among various methods of age estimation using dental tissues, measurement of root dentin translucency (RDT) is said to be the most accurate. Numerous studies have estimated age by measuring RDT in single and double rooted teeth and have shown conflicting results. Only few studies have compared efficacy of using single and double rooted teeth for RDT measurement in age estimation. AIM: To analyze the efficacy of single rooted teeth (SRT) and double rooted teeth (DRT) for measurement of sclerotic dentin (SD) and age estimation...

Background and Aims: Hepatitis C virus (HCV) hepatotropism is associated with intra-peripheral blood mononuclear cell (PBMC) infection that causes post-treatment relapse in RNA seronegative patients. Our understanding of the association of non-viremic hepatic fibrosis with positive anti-HCV IgG antibodies and active hepatocellular damage might be increased by PBMCs screening for intracellular infection. Thus, the goals of this study included evaluation of PBMCs PCR for diagnosing HCV infection, addressing PBMCs plus serum real-time (SRT) PCR benefits over SRT-PCR alone, studying intra-PBMCs distribution of RNA sense and antisense strands, and identifying treatment feasibility in solitary intracellular infection...

Bacteria can grow in the presence of trimethoprim and sulfamethoxazole by expressing antibiotic resistance genes or by acquiring thymine or thymidine from environmental reservoirs to facilitate DNA synthesis. The purpose of this study was to evaluate whether activated sludge serves as a reservoir for thymine or thymidine, potentially impacting the quantification of antibiotic resistant bacteria. This study also assessed the impacts of varying solids retention time (SRT) on trimethoprim and sulfamethoxazole removal during wastewater treatment and single and multi-drug resistance...

The behaviour and removal efficiency of ibuprofen (IBU), diclofenac (DCF), ketoprofen (KPF), and naproxen (NPX) during the real urban wastewater treatment by an experimental full-scale MBR working at high sludge and hydraulic retention time (SRT, HRT) were determined. The MBR worked in denitrification/nitrification conformation at 35.4h of HRT (Q=0.45m(3)/h), 37 d of SRT and a recirculation flow rate of 4Q. The experiments were made under steady-state conditions, reaching a biodegradable organic matter removal higher than 99...

BACKGROUND: The optimal prostate-specific antigen (PSA) level after radical prostatectomy (RP) for defining biochemical recurrence and initiating salvage radiation therapy (SRT) is still debatable. Whereas adjuvant or extremely early SRT irrespective of PSA progression might be overtreatment for some patients, SRT at PSA >0.2 ng/ml might be undertreatment for others. The current study addresses the optimal timing of radiation therapy after RP. PATIENTS AND METHODS: Cohort 1 comprised 293 men with PSA 0...

BACKGROUND: Which men benefit most from adding androgen deprivation therapy (ADT) to salvage radiation therapy (SRT) after prostatectomy has not clearly been defined; therefore, we evaluated the impact of ADT to SRT on failure-free survival (FFS) in men with a rising or persistent PSA after prostatectomy. METHODS: We identified 332 men who received SRT after prostatectomy from 1987 to 2010. Recursive partitioning analysis (RPA) identified favorable, intermediate and unfavorable groups based on the risk of failure after SRT alone...

Bleomycin-induced lung injury leads to surfactant dysfunction and permanent loss of alveoli due to a remodeling process called collapse induration. Collapse induration also occurs in acute interstitial lung disease and idiopathic pulmonary fibrosis in humans. We hypothesized that surfactant dysfunction aggravates lung injury and early remodeling resulting in collapse induration within 7 days after lung injury. Rats received bleomycin to induce lung injury and either repetitive surfactant replacement therapy (SRT: 100mg Curosurf®/kg BW=surf group)) or saline (0...

It has been suggested that people with autism spectrum disorder (ASD) have an increased tendency to use explicit (or intentional) learning strategies. This altered learning may play a role in the development of the social communication difficulties characterizing ASD. In the current study, we investigated incidental and intentional sequence learning using a Serial Reaction Time (SRT) task in an adult ASD population. Response times and event related potentials (ERP) components (N2b and P3) were assessed as indicators of learning and knowledge...

REVIEW
Annemie Van Breussegem, Jeroen M Hendriks, Patrick Lauwers, Paul E Van Schil
Salvage surgery is a relatively new entity in thoracic surgery and oncology. Salvage resection after radiotherapy refers to surgery as only remaining therapeutic option in patients who were treated with high-dose stereotactic radiotherapy (SRT) for early-stage lung cancer or full-dose chemoradiation for locally advanced lung cancer. Indications include locally progressive tumors, recurrent local or locoregional disease, or specific complications after radiotherapy such as lung abscesses or infected, necrotic cavities...
