This study was carried out to induce out-of-season breeding, in the summer, and to achieve high reproductive performance using artificial photoperiod manipulation in the long-day breeding Yangzhou goose. Young geese were subject to a two-phase short-to-long (group A) or a three-phase (long-short-long; group B) photoperiod program February through October. Egg-laying was induced to start similarly in both groups in May, increased to a peak level in July, and then decreased gradually through to October. The peak and post-peak laying rates were higher with the three-phase than with the two-phase program...

An in vitro experiment was performed to determine if biofilm would develop when polyvinylchloride (PVC) test coupons (material used for poultry waterlines) were exposed to low bacterial content warm water (≤1000 cfu/mL, test water) and also to determine if biofilm development would be influenced by adding a sanitizer. PVC sections 2.54 cm long and internal diameter of 1. 90 cm were used as test coupons to grow biofilm. Two coupons were immersed in 600 mL test water in a beaker. Nine beakers were utilized similarly with a total of 18 coupons...

Premenopausal women are known to have less heart disease than their menopausal counterparts and men. However, there is a rising prevalence of coronary artery disease (CAD) in premenopausal females, which necessitates determination of risk factors that negate the effects of hormonal protection. There are few studies describing the prevalence of traditional and emerging risk factors in premenopausal women with CAD. Thus, our objective was to explore the prevalence of traditional and emerging risk factors and features of coronary lesions in premenopausal women with CAD in an Indian population...

Hemin is a unique model compound of heme proteins carrying out variable biological functions. Here the excited state relaxation dynamics of heme model compounds in the ferric form are systematically investigated by changing the axial ligand (Cl/Br), the peripheral substituent (Vinyl/Ethylmeso) and the solvent (Methanol/DMSO) using femtosecond pump-probe spectroscopy upon excitation at 380 nm. The relaxation time constants of these model compounds are obtained by global analysis. Excited state deactivation pathway of the model compounds comprising the decay of the porphyrin excited state (S*) to Ligand to Metal Charge Transfer state (LMCT, t1), back electron transfer from Metal to Ligand (MLCT, t2) and relaxation to the ground state through different electronic spin states of iron (t3 and t4), is proposed along with the vibrational cooling processes...

Context: A significant proportion of athyreotic LT4-treated patients experience hypothyroid-like symptoms. During LT4 replacement, levels of the active hormone triiodothyronine (T3) strictly depend on type-2-deiodinase (D2)-mediated activation of LT4. The Thr92Ala polymorphism and the 258 G/A in the DIO2 gene have been associated with various clinical conditions. Objectives: To investigate the effects of DIO2 polymorphisms in thyroid hormone homeostasis. Design: We compared the pre-surgical hormonal status of thyroidectomized LT4-treated patients who had a similar TSH level, to their post-surgery status, and analyzed their DIO2 genotype in a subgroup of 102/140 (72...

Type 2 deiodinase amplifies and type 3 deiodinase depletes levels of the active form of thyroid hormone, triiodothyronine (T3). Given the opposing activities of these enzymes, we tested the hypothesis that they counteract each other's developmental functions by investigating whether deletion of type 2 deiodinase (encoded by Dio2) modifies sensory phenotypes in type 3 deiodinase-deficient (Dio3-/-) mice. Dio3-/- mice display degeneration of retinal cones, the photoreceptors that mediate daylight and color vision...

Nonthyroidal illness syndrome (NTIS) affects patients with myocardial infarction (MI). Oxidative stress has been implicated as a causative factor of NTIS, and reversed via N-acetylcysteine (NAC). Male Wistar rats submitted to left anterior coronary artery occlusion received NAC or placebo. Decreases in T3 levels were noted in MI-placebo at 10 and 28 days post-MI, but not in MI-NAC. Groups exhibited similar infarct areas whereas MI-NAC exhibited higher ejection fraction (EF) than MI-placebo. Left ventricular systolic (LVSd) and diastolic (LVDd) diameters were also preserved in MI-NAC, but not in MI-placebo...

Thyroid storm or severe thyrotoxicosis results from extreme thyroid hormone elevation. Therapy includes medical management to prevent hormone production, release, recycling, and peripheral conversion while stabilizing adrenergic tone. Thyroid dysfunction is the usual cause but it can be due to excessive thyroid hormone ingestion. Therapeutic plasma exchange (TPE) has been used to rapidly remove protein-bound thyroid hormone. American Society for Apheresis guidelines make a weak recommendation to perform TPE in selected patients in the treatment of thyrotoxicosis based on low quality evidence...

BACKGROUND: Hemodialysis (HD) patients have altered free triiodothyronine (fT3) levels. A low fT3 level is a strong and inverse mortality predictor in HD patients. However, little is known about the relationship between fT3 and left ventricular function in HD patients. METHODS: A total of 128 maintenance HD patients were enrolled in this study. A thyroid function test with blood sampling and echocardiography was conducted. Low-T3 syndrome was defined as fT3 level <3...

PURPOSE: Apparent diffusion coefficient (ADC) histogram analysis has been used to some extent in cervical cancer (CC) to distinguish between low-grade and high-grade tumors. Although this differentiation is undoubtedly helpful, it would be even more crucial in the presurgical setting to determine whether a tumor already gained the potential to metastasize via the lymphatic system. So far, no studies investigated the potential of 3T ADC histogram analysis in CC to differentiate between nodal-positive and nodal-negative entities...

The prognosis of acute coronary syndromes (ACS) is affected by many factors. Normal thyroid homeostasis is known to alter during various critical illnesses, a condition that has been shown to correlate with the severity of the disease and increased mortality. The purpose of this article is to review literature to emphasize the considerable association of thyroid function with the cardiovascular system and summarize all existing evidence with regard to the role of thyroid hormones alterations during ACS. The electronic databases of PubMed, Medline, Scopus, and Cochrane were searched for relevant literature and studies...

INTRODUCTION: Incomplete specimens resulting in residual mesorectum in the patient and an increased risk of local recurrence remains a problem. We have introduced transanal-total mesorectal excision (Ta-TME) in our department to potentially overcome this problem due to more direct access to the lower pelvis in patients undergoing TME for rectal cancer and this article presents our initial experience with the new procedure. MATERIALS AND METHODS: Patients with a T1-T3 mid or low rectal cancer eligible for TME or intersphincteric abdominoperineal excision were selected for a combined transanal and transabdominal laparoscopic resection...

Little is known about the effects of risk factors on attention-deficit/hyperactivity disorder (ADHD) symptom over time. Here, we longitudinally studied the role of candidate genes, pre- and perinatal factors, and their interactions on ADHD symptoms between ages 10 and 18 years. Subjects were part of the general population or clinic-referred cohort of the TRacking Adolescents' Individual Lives Survey (n = 1667). At mean ages of 11.1 (T1), 13.4 (T2), and 16.2 years (T3), ADHD symptoms were assessed with the Child Behavior Checklist...
