We report the expression and characterization of a truncated form of MycA from the Mycosubtilin gene cluster from Bacillus subtilis. The MycA fragment contains a new amino transferase (AMT) tailoring domain, allowing the first detailed study of a PLP-dependent enzyme operating in cis within the PKS and NRPS biosynthetic paradigm. As the AMT domain acts on covalently bound beta-ketothioesters, a...

This paper introduces a method for off-line verification of signatures. The method can verify signatures and detect skilled forgeries with outstanding performance. It is based on matching the questioned signature with a 3-D Reference Knowledge Image (RKI) using Ammar Matching Technique (AMT). The AMT which was developed and modified through the years (1989-2010) is introduced in detail, and the...

The optimal separation conditions and online sample concentration for N,N-dimethyltryptamine (DMT) and related compounds, including alpha-methyltryptamine (AMT), 5-methoxy-AMT (5-MeO-AMT), N,N-diethyltryptamine (DET), N,N-dipropyltryptamine (DPT), N,N-dibutyltryptamine (DBT), N,N-diisopropyltryptamine (DiPT), 5-methoxy-DMT (5-MeO-DMT), and 5-methoxy-N,N-DiPT (5-MeO-DiPT), using micellar EKC (ME...

amegakaryocytic thrombocytopenia (amt) is a rare cause of acquired thrombocytopenia. the pathogenesis and treatment of amt is not clearly known. here we demonstrate a 50-year-old man presented with the clinical manifestations of severe thrombocytopenia (7000 platelets/µl) with a marked decrease to absent of megakaryocytes in the bone marrow. the patient did not respond to intravenous immunoglob...

We present a matching-pricing algorithm for online information labor markets motivated by exploratory study of Amazon Mechanical Turk (AMT). The algorithm addresses many of the challenges surfaced by the AMT study. We find that AMT pricing is largely done using rules of thumb, which results in inaccurate pricing. Such pricing leads to either excessive costs for employers or low income for worke...

With the emphasis on reducing costs and increasing efficiency, a record number of companies are embarking on different forms of advance manufacturing technologies (AMT). AMT are broadly defined by many authors (small and chen, Sheppard and stock) as “ an automated production system of people, machines and tools for the planning and control of the production process, including the procurement of...

This paper investigates two subjective responses to a recorded percussive musical instrument sound displayed in a hapticauditory virtual environment; the responses were Apparent Motion Towards (AMT) and Powerfulness. The system employed a wholebody actuator and a full-range multichannel stereophonic sound compliant with ITU standards. AMT was experienced when whole-body vibratory components wer...

Aim: To evaluate the results of conjunctival autograft transplantation (CAT) combined with amniotic membrane (AMT) surgery in recurrent pterygium cases. Methods: This is a retrospective interventional case series involving patients admitted to our clinic pterygium. Patients' examination and postoperative findings were taken through standard slit-lamp examinations. Fourteen eyes 14 included stud...

PURPOSE To determine if the use of combined HLA matched limbal stem cells allograft with amniotic membrane transplantation (AMT) is a safe and effective prophylactic surgical procedure to prevent corneal graft after penetrating keratoplasty (PK). METHODS We report the case of a 17 years old patient with a history of congenital glaucoma, trabeculectomy and multiple corneal graft rejections, pr...

The ammonium transporter gene family consists of three main clades, AMT, MEP, and Rh. The evolutionary history of the AMT/MEP/Rh gene family is characterized by multiple horizontal gene transfer events, gene family expansion and contraction, and gene loss; thus the gene tree for this family of transporters is unlike the organismal tree. The genomes of angiosperms contain genes for both electrog...
