Potential long term effects on brain development are a concern when drugs are used to treat depression and anxiety in childhood. In this study, male juvenile rhesus monkeys (three-four years of age) were dosed with fluoxetine or vehicle (N=16/group) for two years. Histomorphometric examination of cortical dendritic spines conducted after euthanasia at one year postdosing (N=8/group) suggested a trend toward greater dendritic spine synapse density in prefrontal cortex of the fluoxetine-treated monkeys. During dosing, subjects were trained for automated cognitive testing, and evaluated with a test of sustained attention...

INTRODUCTION: Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease linked to repetitive head injuries. Chronic traumatic encephalopathy symptoms include changes in mood, behavior, cognition, and motor function; however, CTE is currently diagnosed only postmortem. Using a rat model of recurrent traumatic brain injury (TBI), we demonstrate rodent deficits that predict the severity of CTE-like brain pathology. METHODS: Bilateral, closed-skull, mild TBI was administered once per week to 35 wild-type rats; eight rats received two injuries (2×TBI), 27 rats received five injuries (5×TBI), and 13 rats were sham controls...

Molecular diagnostic assays offer both exquisite sensitivity and the ability to test a wide variety of sample types. Varioustypes of environmental sample, such as detritus and concentrated water, might provide a useful adjunct to sentinels in routinezebrafish health monitoring. Similarly, antemortem sampling would be advantageous for expediting zebrafish quarantine,without euthanasia of valuable fish. We evaluated the detection of Mycobacterium chelonae, M. fortuitum, M. peregrinum,Pseudocapillaria tomentosa, and Pseudoloma neurophilia in zebrafish, detritus, pooled feces, and filter membranes after filtration of 1000-, 500-, and 150-mL water samples by real-time PCR analysis...

PURPOSE: The DBA/2J mouse has been described as a model for congenital experimental glaucoma. It develops anterior segment anomalies with synechiae and pigment dispersion leading to raised intraocular pressure (IOP) and glaucomatous damage. However there are serious practical considerations when using this model in longitudinal studies. METHODS: We followed 118 mice from 12 - 48 weeks of age in a pharmaceutical trial. Here we report on the findings in control animals (n=37)...

A high-fat diet (HFD) can have a negative effect on bone quality in young and old people. Although bone healing in children is normally efficient, there is no evidence that children who have a diet rich in fat have compromised bone fracture regeneration compared with children with recommended dietary fat levels. The purpose of the present study was to evaluate the effects of an HFD on bone healing in growing female rats. Twenty-six postweaning female Wistar rats were divided into two groups (13 animals per group): a standard diet (SD) group and an HFD (with 60% of energy from fat) group...

Pituitary adenylate cyclase activating polypeptide (PACAP) and its cognate receptor 1 (PAC1), have been implicated in the pathophysiology of the Sudden Infant Death Syndrome (SIDS). Two main risk factors for SIDS are prone sleeping and cigarette smoke exposure. Using piglet models of these risk factors, intermittent hypercapnic hypoxia (IHH-mimicking rebreathing in prone position) and nicotine (main reinforcing element of cigarettes), this study aimed to determine their effects on PACAP and PAC1 protein expression in the medulla...

The IJME Sixth National Bioethics Conference (6th NBC), on the theme "Healing and dying with dignity: ethical issues in palliative care, end-of-life care and euthanasia", was held in Pune, Maharashtra from January 12-15, 2017. Palliative care (PC) and end-of-life care (EOLC) are closely related areas of concern, yet they have been neglected so far. There is an urgent need to discuss these issues in India due to the changing demographics, socioeconomic and work profiles of the population, people's living conditions and health status, and the contexts of the country's population...

BACKGROUND: Myocardial infarction (MI) is one of the leading causes of morbidity and mortality worldwide. Dietary intervention on adverse cardiac remodeling after MI has significant clinical relevance. Rosemary leaves are a natural product with antioxidant/anti-inflammatory properties, but its effect on morphology and ventricular function after MI is unknown. METHODS AND RESULTS: To determine the effect of the dietary supplementation of rosemary leaves on cardiac remodeling after MI, male Wistar rats were divided into 6 groups after sham procedure or experimental induced MI: 1) Sham group fed standard chow (SR0, n = 23); 2) Sham group fed standard chow supplemented with 0...

The issue of voluntary active euthanasia was thrust into the public policy arena by the Stransham-Ford lawsuit. The High Court legalised voluntary active euthanasia - however, ostensibly only in the specific case of Mr Stransham-Ford. The Supreme Court of Appeal overturned the High Court judgment on technical grounds, not on the merits. This means that in future the courts can be approached again to consider the legalisation of voluntary active euthanasia. As such, Stransham-Ford presents a learning opportunity for both sides of the legalisation divide...

Whether persons wishing to have doctor-assisted suicide or voluntary active euthanasia may make a court application based on their rights in the Constitution has not been answered by the Appeal Court. Therefore, if Parliament does not intervene beforehand, such applications can be made - provided the applicants have legal standing, full arguments are presented regarding local and foreign law, and the application evidence is comprehensive and accurate. The Appeal Court indicated that the question should be answered by Parliament because 'issues engaging profound moral questions beyond the remit of judges to determine, should be decided by the representatives of the people of the country as a whole'...

It is a worldwide trend that more households are having pets or companion animals. Hence, there has been an increasing number of animal lovers experience companion animal loss bereavement. This form of bereavement has not been explored in Chinese societies. We conducted a qualitative study using in-depth interviews with 31 animal lovers and recruited through convenience and snowball sampling in Hong Kong. Companion animal loss bereavement appears to share similar features to other forms of bereavement but also has its unique features...

Since the first attempt in 1968, survival following pig-to-primate liver xenotransplantation (LXT) has been limited. We evaluated a model utilizing α-1,3-galactosyltransferase knockout donors, continuous post-transplant infusion of human prothrombin concentrate complex and immunosuppression including anti-thymocyte globulin, FK-506, methylprednisone and co-stimulation blockade (belatacept, n=3 or anti-CD40mAb, n=1) to extend survival. Baboon #1 remained well until POD25 when euthanasia was required due to cholestasis and plantar ulcers...

N-acylethanolamines (NAEs) are endogenous lipid ligands for several receptors including cannabinoid receptors and peroxisome proliferator-activated receptor-alpha (PPAR-α), which regulate numerous physiological functions. Fatty acid amide hydrolase (FAAH) is, largely, responsible for the degradation of NAEs. However, at high concentrations of ethanolamines and unesterified fatty acids, FAAH can also catalyze the reverse reaction, producing NAEs. Several brain insults such as ischemia and hypoxia increase brain unesterified fatty acids...

Many aquatic and terrestrial avian species inadvertently ingest lead (Pb) in the form of spent or fragmented ammunition, mistaking it for food or grit. Previous studies in our laboratory have shown that ingestion of even a single 45-mg pellet can significantly increase blood-Pb levels and significantly inhibit the enzyme delta aminolevulinic-acid dehydratase (δ-ALAD) for a period of greater than 4 weeks. In the current study, proven breeder pairs of domestic Roller pigeons were housed in individual cages...

BACKGROUND: Esophageal ulceration and fistula are complications of pulmonary vein isolation using thermal energy sources. Irreversible electroporation is a novel, nonthermal ablation modality for pulmonary vein isolation. A single 200 J application can create deep myocardial lesions. Acute and chronic effects of this new energy source on the esophagus are unknown. METHODS AND RESULTS: In 8 pigs (±70 kg), the suprasternal esophagus was surgically exposed. A linear suction device with a single 35-mm long and 6-mm wide protruding linear electrode inside a plastic suction cup was used for ablation...
