OBJECTIVE: To determine the safety and pharmacokinetics of alpha-1 antitrypsin (AAT) in adults and children. RESEARCH DESIGN AND METHODS: Short term AAT treatment restores euglycemia in the non-obese mouse model of type 1 diabetes. A phase I multicenter study in 16 subjects with new-onset type 1 diabetes studied the safety and pharmacokinetics of Aralast NPTM (AAT). This open-label, dose-escalation study enrolled eight adults ages 16-35 and eight children ages 8-15 within 100 days of diagnosis, to receive 12 infusions of AAT: a low dose of 45 mg/kg weekly for six weeks, followed by a higher dose of 90 mg/kg for six weeks...

Coccidiosis caused by Eimeria in poultry is endemic to poultry operations and results in decreased feed intake, diarrhea, and decreased weight gain. The goal was to determine the effect of Eimeria maxima infection on the expression of genes that encode peptide and amino acid transporters (AATs), and also to determine whether decreased feed intake contributes to the change in gene expression by including a pair-fed group of broilers. Three groups of male Ross broilers: 1) not infected, 2) infected, and 3) not infected pair-fed groups were used...

BACKGROUND: Refrigerated eye-drops have been advocated in cases of ocular allergies to provide a soothing effect upon instillation. This notion continues to be promoted by practitioners for artificial tears (AT) in the management of dry eye (DE) with little support in the literature. To further substantiate claims of a soothing effect of cold eye-drops, the aim of this study was to determine if refrigeration of an AT enhanced the subjective comfort upon instillation. METHODS: Participants with mild to moderate DE participated in an open label contralateral study of two weeks duration...

Chronic obstructive pulmonary disease affects 10% of the worldwide population, and the leading genetic cause is α-1 antitrypsin (AAT) deficiency. Due to the complexity of the murine locus, which includes up to six Serpina1 paralogs, no genetic animal model of the disease has been successfully generated until now. Here we create a quintuple Serpina1a-e knockout using CRISPR/Cas9-mediated genome editing. The phenotype recapitulates the human disease phenotype, i.e., absence of hepatic and circulating AAT translates functionally to a reduced capacity to inhibit neutrophil elastase...

OBJECTIVE: Idiopathic Parkinson's disease (IPD) is the second most common neurodegenerative disorder, often complicated by dementia. Cardiovascular risk factors and spontaneous cerebral emboli (SCE) are strongly associated with Alzheimer's (AD) and vascular dementia (VaD). We measured SCE in the middle cerebral artery and arterial wall volume in the extracranial arteries in patients with IPD and controls, and explored the relationships with structural and physiological MRI brain neurovascular measures...

BACKGROUND: Motor rehabilitation after brain damage relies on motor re-learning as induced by specific training. Non-invasive brain stimulation (NIBS) can alter cortical excitability and thereby has a potential to enhance subsequent training-induced learning. Knowledge about any priming effects of NIBS on motor learning in healthy subjects can help to design targeted therapeutic applications in brain-damaged subjects. OBJECTIVE: To examine whether complex motor learning in healthy subjects can be enhanced by intermittent theta burst stimulation (iTBS) to primary motor or sensory cortical areas...

Corticosteroid resistance following acute GVHD (SR-aGVHD) results in high morbidity and mortality after allogeneic hematopoietic cell transplantation (HCT). Current immunosuppressive therapies for SR-aGVHD provide marginal effectiveness due to poor response or excessive toxicity, primarily from infection. Alpha-1 antitrypsin (AAT), a naturally abundant serine protease inhibitor, is capable of suppressing experimental GVHD by down-modulation of inflammation and increasing ratios of regulatory to effector T cells...

BACKGROUNDS: Clopidogrel is widely used in Coronary Heart Disease (CHD) patients undergoing percutaneous coronary intervention (PCI) to prevent thrombotic events. However, clopidogrel response variability (CRV) may affect the patients' clinical outcomes. The current data have shown that genetic factors play an important role in CRV. The aim of this research is to investigate the association of pregnane X receptor (PXR, also called NR1I2) genetic polymorphisms with the clinical efficacy of clopidogrel in patients undergoing PCI...

Alpha 1 antitrypsin deficiency is a hereditary condition characterized by low alpha 1 proteinase inhibitor (also known as alpha 1 antitrypsin [AAT]) serum levels. Reduced levels of AAT allow abnormal degradation of lung tissue, which may ultimately lead to the development of early-onset emphysema. Intravenous infusion of AAT is the only therapeutic option that can be used to maintain levels above the protective threshold. Based on its biochemical efficacy, AAT replacement therapy was approved by the US Food and Drug administration in 1987...

RATIONALE: α1-antitrypsin (AAT) deficiency-related emphysema is the fourth leading indication for lung transplantation. Chymotrypsin-like elastase 1 (Cela1) is a digestive protease that is expressed during lung development in association with regions of elastin remodeling, exhibits stretch-dependent expression during lung regeneration, and binds lung elastin in a stretch-dependent manner. AAT covalently neutralizes Cela1 in vitro. OBJECTIVES: We sought to determine the role of Cela1 in postnatal lung physiology, whether it interacted with AAT in vivo, and any effects it may have in the context of AAT deficiency...

Strong implicit responses to food have evolved to avoid energy depletion but contribute to overeating in today's affluent environments. The Approach-Avoidance Task (AAT) supposedly assesses implicit biases in response to food stimuli: Participants push pictures on a monitor "away" or pull them near with a joystick that controls a corresponding image zoom. One version of the task couples movement direction with image content-independent features, for example, pulling blue-framed images and pushing green-framed images regardless of content ('irrelevant feature version')...

The approximate number system (ANS) is an innate cognitive template that allows for the mental representation of approximate magnitude, and has been controversially linked to symbolic number knowledge and math ability. A series of recent studies found that an approximate arithmetic training (AAT) task that draws upon the ANS can improve math skills, which not only supports the existence of this link, but suggests it may be causal. However, no direct transfer effects to any measure of the ANS have yet been reported, calling into question the mechanisms by which math improvements may emerge...

Niccolò Ugo Foscolo (1778-1827), known as Ugo, is one of the masters of the Italian poetry. A writer and a revolutionary, he embraced the ideals of the French Revolution and took part in the stormy political discussions, which the fall of the Republic of Venice had provoked. Despite his poor health, Foscolo lived an adventurous life serving as a volunteer in the Guardia Nazionale and in the Napoleonic army. Following Napoleon's fall (1814), he went into voluntary exile in early 1815. He reached London in Sept...
