In plants and bacteria that use a Type II fatty acid synthase (FAS), isozymes of acyl-acyl carrier protein (ACP) thioesterase (TEs) hydrolyze the thioester bond of acyl-ACPs, terminating the process of fatty acid biosynthesis. These TEs are therefore critical in determining the fatty acid profiles produced by these organisms. Past characterizations of a limited number of plant-sourced acyl-ACP TEs have suggested a thiol-based, papain-like catalytic mechanism, involving a triad of Cys, His, and Asn residues...

For more than 20 years, the American College of Physicians (ACP) has advocated for the need to address firearm-related injuries and deaths in the United States. Yet, firearm violence continues to be a public health crisis that requires the nation's immediate attention. The policy recommendations in this paper build on, strengthen, and expand current ACP policies approved by the Board of Regents in April 2014, based on analysis of approaches that the evidence suggests will be effective in reducing deaths and injuries from firearm-related violence...

This study explored the perceived goals, barriers, and strategies that characterize family interactions about advance care planning (ACP), which is instrumental in guiding end-of-life care. Discussions within the family context can significantly improve end-of-life decision making but are complicated, partly because participants are attempting to achieve multiple, and often competing, goals. Participants (n = 75) responded to a hypothetical scenario about a conversation with a parent about ACP by completing an anonymous online survey...

Contemporary caries prevention protocols recommend not only effective remineralizing agents but also ecological measures to reverse the dental plaque dysbiosis responsible for the disease pathogenesis. There is a high-level of evidence supporting the remineralizing efficacy of Casein Phosphopeptide-Amorphous Calcium Phosphate (CPP-ACP) from studies around the world. There is now emerging evidence that CPP-ACP may also have a beneficial influence on the dental plaque microbial ecology and homeostasis. The ecological cariostatic effects of CPP-ACP are believed to be mediated predominantly through its anti-adhesion, buffering, and biofilm disrupting actions...

Advanced Clinical Practitioners (ACPs) are a rapidly growing workforce worldwide with the USA showing the highest absolute number and rate per population, followed by the Netherlands, Canada, Australia, Ireland and New Zealand (Maier et al 2016). Whilst many practitioners are nurses by background, the development of the role has encouraged the inclusion of other professions such as physiotherapists, pharmacists and paramedics. The progression of the ACP role involves the acquisition of new skills alongside post graduate academic education at Masters level and peer support (NHS Education for Scotland 2012, Aguilard et al 2017, Health Education England 2017)...

Skillfully implemented mechanical ventilation (MV) may prove of immense benefit in restoring physiologic homeostasis. However, since hemodynamic instability is a primary factor influencing mortality in acute respiratory distress syndrome (ARDS), clinicians should be vigilant regarding the potentially deleterious effects of MV on right ventricular (RV) function and pulmonary vascular mechanics (PVM). During both spontaneous and positive pressure MV (PPMV), tidal changes in pleural pressure (PPL ), transpulmonary pressure (PTP , the difference between alveolar pressure and PPL ), and lung volume influence key components of hemodynamics: preload, afterload, heart rate, and myocardial contractility...

BACKGROUND: We modified and evaluated an advance care planning (ACP) intervention, which had been shown to improve compliance with patient's end of life (EoL) wishes, in a different patient population. METHODS: Patients with incurable cancer, and a Family Member (FM), were randomised one-to-one to usual care or usual care plus an ACP intervention, between April 2014 and January 2017. Oncologists and participants were non-blinded. ACP was based on the Respecting Patient Choices model, with an offer to provide individualised ranges for typical, best-case and worst-case scenarios for survival time...

BACKGROUND: Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, is an important pest of citrus worldwide because it transmits the causal bacteria causing huanglongbing (HLB). We investigated the effects and persistence of two soil application rates of thiamethoxam on ACP populations in two flushing seasons in the field. The residues of thiamethoxam and clothianidin in the fruit were detected to evaluate food safety. RESULTS: Soil application of 50% thiamethoxam water dispersible granule at concentrations of 4 and 10 g tree-1 significantly decreased ACP populations, and there was a positive correlation between the control efficacy and persistence of thiamethoxam and clothianidin in leaves, providing longer-term protection up to 90 days in the fall compared with 60 days in the spring...

Amorphous calcium phosphate (Ca3 (PO4 )2 xnH2 O; n = 3-4.5; ACP) is a precursor phase of the mineral hydroxyapatite (Ca5 (PO4 )3 (OH); HAP) that in natural settings occurs during both authigenic and biogenic mineral formation. In aqueous solutions ACP transforms rapidly to the crystalline phase. The transformation rate is highly dependent on the prevailing physico-chemical conditions, most likely on: Ca & PO4 concentration, pH and temperature. In this study, we conducted a calcium phosphate precipitation experiment at 20 °C and pH 9...

The aim of the present study was to investigate effects of dietary yeast culture on immune response related to TLR2-MyD88-NF-kβ signaling pathway, antioxidant capability and disease resistance against Aeromonas hydrophila for Ussuri catfish (Pseudobagrus ussuriensis). A total of 240 Ussuri catfish (mean weight of 7.39 ± 0.32 g) were randomly distributed into four groups that fed diets containing 0 (Y0), 10 (Y1), 20 (Y2) and 30 (Y3) g kg-1 yeast culture for 8 weeks. The results indicated that dietary 10 g kg-1 yeast culture supplementation significantly down-regulated mRNA levels of TLR2, MyD88, NF-kβ p65, IL-1β and IL-8 in the liver tissue compared with the control group (P < 0...

Biomineralization in vertebrates is initiated via amorphous calcium phosphate (ACP) precursors. These precursors infiltrate the extracellular collagen matrix where they undergo phase transformation into intrafibrillar carbonated apatite. Although it is well established that ACP precursors are released from intracellular vesicles through exocytosis, an unsolved enigma in this cell-mediated mineralization process is how ACP precursors, initially produced in the mitochondria, are translocated to the intracellular vesicles...

During polyketide and fatty acid biosynthesis, the growing acyl chain is attached to the acyl carrier protein via a thioester linkage. The acyl carrier protein interacts with other enzymes that perform chain elongation and chain modification on the bound acyl chain. Most type I polyketide synthases and fatty acid synthases contain only one acyl carrier protein. However, polyunsaturated fatty acid synthases from deep-sea bacteria contain anywhere from two to nine acyl carrier proteins. Recent studies have shown that this tandem acyl carrier protein feature is responsible for the unusually high fatty acid production rate of deep-sea bacteria...

Fish are the most diverse species of all vertebrate groups, and their blood cells have shown variable characteristics in terms of morphology. Cytochemical staining for enzyme activity in blood leukocytes will help assess the immune function of fish. We characterize blood cells from crucian carp (Carassius auratus) and grass carp (Ctenopharyngodon idellus) by using a Diff-Quick stain as well as different cytochemical methods. Blood specimens obtained from crucian carp and grass carp were evaluated after cytochemical staining for acid phosphatase (ACP), alkaline phosphatase (ALP), naphthol AS chloroacetate esterase (AS-DNCE), naphthyl acetate esterase (NAE), α-naphthyl butyrate esterase (NBE), peroxidase (MPO) and periodic acid-Schiff's reaction (PAS) using commercial kits...

Posttranslational modifications, such as N ε-lysine acetylation, regulate protein function. N ε-lysine acetylation can occur either nonenzymatically or enzymatically. The nonenzymatic mechanism uses acetyl phosphate (AcP) or acetyl coenzyme A (AcCoA) as acetyl donor to modify an N ε-lysine residue of a protein. The enzymatic mechanism uses N ε-lysine acetyltransferases (KATs) to specifically transfer an acetyl group from AcCoA to N ε-lysine residues on proteins. To date, only one KAT (YfiQ, also known as Pka and PatZ) has been identified in Escherichia coli Here, we demonstrate the existence of 4 additional E...

In this paper, we developed a label-free and sensitive fluorescence sensor for acid phosphatase (ACP) and its inhibitor parathion-methyl (PM) detection based on glutathione-functionalized graphene quantum dots (GQDs@GSH). Upon addition of MnO2 nanosheets, the fluorescence of GQDs@GSH could be efficiently quenched via a fluorescence resonance energy transfer. ACP could easily catalyze the hydrolysis of L-Ascorbic acid-2-phosphate (AAP) to ascorbic acid (AA), which could reduce MnO2 nanosheets to Mn2+ in acidic environment, leading to dramatically increase of the fluorescence intensity of GQDs@GSH...
