A simple and highly efficient procedure for the synthesis of novel thiazol-2-amines, via Mannich reaction with secondary amines, is described. The newly synthesized derivatives 8(a-e) and 9(a-e) were characterized by (1)H NMR, (13)C NMR, IR, Mass spectroscopy and elemental analysis. All the derivatives were evaluated for their in-vitro anti-microbial activity against a panel of pathogenic strains of bacteria and fungi. The SAR showed that the secondary amines had a significant impact on the in-vitro antimicrobial activity of this class of agents...

Aeromonas veronii is a gram-negative pathogen capable of infecting both fish and mammals, including humans, and natural infection in fish results in irreparable damage to the aquaculture industry. Lactic acid bacteria (LAB) have a number of properties that make them attractive candidates as delivery vehicles for presentation to the mucosa sites of compounds with pharmaceutical interest, in particular vaccines. In this study, we generated two recombinant Lactobacillus casei (surface-displayed or secretory) expressing the OmpAI of A...

Eric Soupene, Frans A Kuypers
De novo lipid synthesis and scavenging of fatty acids (FA) are processes essential for the formation of the membrane of the human pathogen Chlamydia trachomatis (C.t.). Host FA are assimilated via esterification by the bacterial acyl-acyl carrier protein (ACP) synthase AasC but inhibitors of the host acyl-CoA synthetase enymes ACSL also impaired growth of C.t. in human cells. In E. coli, activity of AasC was sensitive to triacsin C and rosiglitazone G. The absence of a triacsin C-insensitive pathway and the increased inhibition by rosiglitazone G confirmed the sensitivity of the bacterial acyl-ACP synthase to these drugs in infected human cells...

In this paper, we developed a sensitive fluorescence biosensor for tyrosinase (TYR) and acid phosphatase (ACP) activity detection based on nitrogen-doped graphene quantum dots (N-GQDs). Tyrosine could be catalyzed by TYR to generate dopaquinone, which could efficiently quench the fluorescence of N-GQDs, and the degree of fluorescence quenching of N-GQDs was proportional to the concentration of TYR. In the presence of ACP, l-Ascorbic acid-2-phosphate (AAP) was hydrolyzed to generate ascorbic acid (AA), and dopaquinone was reduced to l-dopa, resulting in the fluorescence recovery of the quenched fluorescence by dopaquinone...

An engineered reversal of the β-oxidation cycle (r-BOX) and the fatty acid biosynthesis (FAB) pathway are promising biological platforms for advanced fuel and chemical production in part due to their iterative nature supporting the synthesis of various chain length products. While diverging in their carbon-carbon elongation reaction mechanism, iterative operation of each pathway relies on common chemical conversions (reduction, dehydration, and reduction) differing only in the attached moiety (acyl carrier protein (ACP) in FAB vs Coenzyme A in r-BOX)...

BACKGROUND: Although it is recommended that all terminally ill patients receive advance care planning (ACP), this is occasionally challenging because of the difficulty in predicting survival. There are some indexes for predicting survival, but few are accurate, especially at the terminal stages of illness. METHODS: Twenty-two patients at the terminal stages of cancer were retrospectively analyzed. We assessed their physical activity and condition using activities of daily living (ADL) scores for 1 month before the death...

Azospirillum brasilense can swim and swarm owing to the activity of a constitutive polar flagellum (Fla) and inducible lateral flagella (Laf), respectively. Experimental data on the regulation of the Fla and Laf assembly in azospirilla are scarce. Here, the coding sequence (CDS) AZOBR_p1160043 (fabG1) for a putative 3-oxoacyl-[acyl-carrier protein (ACP)] reductase was found essential for the construction of both types of flagella. In an immotile leaky Fla- Laf- fabG1::Omegon-Km mutant, Sp245.1610, defects in flagellation and motility were fully complemented by expressing the CDS AZOBR_p1160043 from plasmid pRK415...

AIMS: To study effects of treatment voltage and time of in-package atmospheric cold plasmas (ACP) on quality of raw chicken meat. METHODS AND RESULTS: Meat was packed in trays in air, treated with ACP, and stored at 4°C for 24 h or 3 d. Increasing voltage from 55 to 80 kV caused increasing O3 inside packages, but had no effects on microbes, color, and pH after 24-h storage at 4°C. There were no differences in O3 , microbes, color lightness, and pH between treatment times 3, 6 and 9 min at 80 kV after 3-d storage...

BACKGROUND: Advance care planning (ACP) empowers patients to consider and communicate their current and future treatment goals. However, it can be an emotionally charged process for patients with kidney disease and their caregivers. This study aimed to describe the perspectives and attitudes of patients with end-stage renal disease (ESRD) and their caregivers toward ACP. STUDY DESIGN: Qualitative study. SETTING & PARTICIPANTS: Patients with ESRD (n=24) and their caregivers (n=15) aged 36 to 91 years at various stages of ACP ("not commenced," "in progress," or "completed") from 3 renal services...

This commentary reflects on a study to determine the efficacy of an advance care planning (ACP) website in increasing planning documentation. It is interesting to see that ACP is considered to be a regular intervention. ACP thus ceases to be something to believe in or not and becomes a normal intervention, the efficacy of which can be studied. The study also shows that ACP is a concept which can take many forms, that ACP in itself is almost an umbrella term and that physicians need not take the central role in ACP...

S Buis, C Veen
When talking about 'advance care planning' (ACP), people regularly state that they do not want to go to the hospital any more. There are several reasons why this wish may be unclear in acute situations: preferred treatment is not always available or discussed, there may be different reasons for the 'no more hospital' statement and the emergency department is often insufficiently prepared for carrying out limited evaluations or treatments. To provide appropriate care, we recommend to (a) discuss the limitations of ACP, (b) evaluate preferences in the current context, (c) improve communication between primary and secondary care and to consider alternative options, (d) regularly evaluate current policies and (e) invest in local initiatives to prevent admission or long-term admission or to enable people to stay home...

Growing evidence suggests a low engagement in advance care planning (ACP) among ethnic minorities in the U.S. The purpose of this study was to synthesize findings from prior research about ACP among ethnic minorities. An extensive literature search was conducted using multiple electronic databases. After applying inclusion criteria, 26 studies were included. Four categories of facilitators and barriers to ACP were identified: (1) Socio-demographic factors, (2) health status, literacy and experiences, (3) cultural values, and (4) spirituality...

BACKGROUND: Pancreatic fibrosis is a key pathological feature of alcoholic chronic pancreatitis (ACP). Bacterial endotoxin lipopolysaccharide (LPS) is considered as an important cofactor in the fibrogenesis of ACP. However, there are limitations in the use of exogenous LPS for evaluating the role of endotoxin in ACP pathogenesis. In this study we determined the relationship between the concentration of LPS in the portal vein and pancreatic type I collagen (Col1) content in chronic alcohol-fed rats...
