BACKGROUND: The majority of chemoradiation (CRT) trials for locally advanced head and neck squamous cell carcinoma (HNSCC) have relied on platinum-based chemotherapy regimens administered every-3-weeks. However, given the increased utilization of weekly platinum regimens, it remains unclear how different chemotherapy schedules compare regarding efficacy and toxicity. METHODS: We retrospectively identified 212 patients with HNSCC who were treated at a single academic medical center with concurrent platinum-based CRT given weekly (N = 68) or every-three-weeks (N = 144)...

Pathological staging and grading are crucial for risk assessment in non-muscle-invasive bladder cancer (NMIBC). Molecular grading might support pathological evaluation and minimize interobserver variability. In this study, the well-established breast cancer markers ESR1, PGR, ERBB2, and MKI67 were evaluated as potential molecular markers to support grading and staging in NMIBC. We retrospectively analyzed clinical data and formalin-fixed paraffin-embedded tissues (FFPE) of patients with NMIBC. Messenger RNA (mRNA) expression of the aforementioned markers was measured by single-step reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) using RNA-specific TaqMan assays...

Escalating product recalls as a consequence of Salmonella-contaminated poultry products have resulted in detrimental economic impacts in the poultry industry. One potential long-term alternative method to Salmonella prevention is genetic selection to improve innate resistance. This study evaluated the ex vivo effects of Salmonella Heidelberg (SH) on phagocytic and bactericidal leukocyte function in turkeys from six pedigree lines (A-F). Day-of-hatch poults (n = 48) were placed and raised in cages (2 birds/gender/genetic line/cage) to 35 d when heterophils and peripheral blood mononuclear cells (PBMCs) were extracted from males and females of each line...

BACKGROUND: The control of container-inhabiting mosquitoes is mainly based on environmental management with special emphasis on community participation e.g. source reduction by elimination or modification of water bodies. However, citizens are often not aware of the problems related to urban mosquito control or just ignore the advice provided during anti-mosquito control campaigns. In particular, cemeteries contain favourite breeding sites for container-inhabiting mosquitoes like Ochlerotatus j...

Ghrelin is a hormone that stimulates feed intake and regulates energy homeostasis. A link has been observed in sheep, in which simulated feedings at scheduled meal times resulted in an increase in ghrelin concentrations. The present study sought to characterize the effect of feeding cues outside of scheduled meal times on circulating ghrelin concentrations in sheep. Katahdin wethers (age 201 ± 4.9 d; weight 35 ± 1.2 kg) were not offered feed (CONT; = 5), offered 275 g of feed (FED; = 5), or fitted with a muzzle and offered 275 g of feed (SHAM; = 5) during the sampling period, which began 2...

OBJECTIVE: Smoking and hypertension are important risk factors in the development of cardiovascular disease (CVD). Control rates of hypertension are quite poor with only <50% of patients achieving target blood pressure (BP) after antihypertensive monotherapy. Smokers may have a blunted response to antihypertensive drugs but this has not been properly investigated. Therefore we studied the interaction between smoking status and BP response in never-treated hypertensive patients. DESIGN AND METHOD: We studied 305 untreated hypertensive subjects (mean age 51 ± 1, mean ± SEM, F = 124) classified according to their smoking status; non- smoker (n = 134), smoker (n = 64) and ex- smoker (n = 104)...

INTRODUCTION: The prevalence of primary monosymptomatic nocturnal enuresis (PMNE) varies from 1.6% to 15%. Although treatment with enuretic alarms has been used for a long period of time, there are many disadvantages, including the necessity for long-term use and the high percentage of children who are resistant to such therapy. We hypothesized that more intense use of the alarm system would accelerate the process of forming the conditioned response to awakening, caused by the desire to urinate and, probably, increase the percentage of patients with positive results...
