BACKGROUND Acanthamoeba is the genus of free-living amoebae that is most frequently isolated in nature. To date, 20 Acanthamoeba genotypes have been described. Genotype T4 is responsible for approximately 90% of encephalitis and keratitis cases. Due to the ubiquitous presence of amoebae, isolation from environmental sources is not uncommon; to determine the clinical importance of an isolation, ...

BACKGROUND Both organ-preserving concurrent (chemo)radiotherapy ((C)RT) and organ-sacrificing surgery (total laryngectomy) are used for treatment of advanced laryngeal cancer. The purpose of this study was to present the assessment of our treatment protocol for T3 (C)RT and T4 disease (total laryngectomy + postoperative RT). METHODS We conducted a retrospective cohort study in 182 consecutive...

Serum levels of T3, T4, and TSH hormones, some elements, and glucose with regard to their involvement for growth retardation in yearling rams were investigated. A total of 70 yearling rams of the Akkaraman breed, 50 of which were classified with a retarded growth, and the remaining 20 were classified as normal, were included in the study. Serum total T3, total T4, and TSH were measured using ch...

Consequences of prenatal exposure to ethanol (E) include morphological, physiological, and cognitive deficits and are collectively classified as fetal alcohol spectrum disorders. Adult prenatal E exposed offspring show insulin resistance, and given that in utero hyperglycemic environment can cause metabolic disorders in subsequent generations; we investigated the effects of grandmaternal E on f...

The yield of preoperative PET/CT (PET/CT) for regional and distant metastases for thin/intermediate thickness melanoma is low. Objective of this study is to determine if PET/CT performed for T4 melanomas helps guide management and alter treatment plans. Methods. Retrospective cohort of 216 patients with T4 melanomas treated at two tertiary institutions. Fifty-six patients met our inclusion crit...

OBJECTIVE To investigate the effects of hepatic radiofrequency ablation (RFA) in patients with malignant liver disease with respect to inflammation activation and stress response. MATERIALS AND METHODS In an observational trial, we investigated the physiologic parameters of 17 patients (20 interventions) who underwent percutaneous RFA under general anesthesia after applying total intravenous ...

Ideal bedding management is essential for optimal health, welfare, and growth performance of dairy calves. The study was conducted in order to compare the effect different materials on Murrah buffalo calves (n=20) less than 4 months age were selected divided into four groups (5 animals/group), viz. T1: Concrete floor, T2: floor bedded with sand, T3: wheat straw T4: rubber mat. Body weight body ...

1. Effects of endosulfan, malathion and carbaryl on circulating T4, T3 and T3/T4 ratio in the freshwater catfish, C. batrachus have been studied during reproductively active phases, i.e. vitellogenic and post-vitellogenic phases of its annual reproductive cycle. 2. Endosulfan provoked a significant increase in T4 and a decrease in T3 as well as the T3/T4 ratio. 3. Malathion decreased T3 and T3/...

Alterations in thyroid function tests are very common in patients with NTI. Multiple, complex, and incompletely understood mechanisms are involved in these abnormalities. Knowledge of these abnormalities is necessary to avoid errors in the diagnosis of thyroid disease. Measurement of serum TSH, free T4, and free T3 levels by direct equilibrium dialysis/RIA methods probably yield most useful (ac...

Background: The secretion of thyroxine (T4) as the main hormone of thyroid gland is regulated by androgens. The present study aimed to evaluate the effect of testosterone and finasteride administration and castration on serum levels of T4 and to show the effect of this regulation on total body weight, weight of testis, and the weight of prostate. Methods: Male adult rats (n = 32) were divided i...
