The ability to adapt to adverse environmental conditions encountered in food and during host infection is a sine qua non for a successful Listeria monocytogenes infection. This ability is likely to depend on complex regulatory pathways controlled by a number of key regulators. We utilized the pORI19 plasmid integration system to analyze the role of six putative regulatory loci in growth under s...
For bacteria, cysteine thiol groups in proteins are commonly used as thiol-based switches for redox sensing to activate specific detoxification pathways and restore the redox balance. Among the known thiol-based regulatory systems, the MarR/DUF24 family regulators have been reported to sense and respond to reactive electrophilic species, including diamide, quinones, and aldehydes, with high spe...
1 Introduction There are now many different approaches to the computational modelling of cognition, e.g. and neurophysiologically prescribed connectionist models (O'Reilly & Munakata, 2000). The relative value of different approaches is a hotly debated topic, with each presented as an alternative to the others; that is, that they are in opposition to one another, e.g. However, an alternative pe...
The study aimed to analyze the financial feasibility of implementing robotic milking on a dairy farm in western Santa Catarina/Brazil. This is descriptive case with qualitative basis using semi-structured interviews. Based cost measurement for implementation period activity 2022, comparative analysis was made incremental cash flow relative transition from conventional milking. One major finding...
Background and Aim : Myeloproliferative neoplasms are clonal and heterogeneous disorders of hematopoietic stem cells lead to increase of one or more cell lines in the blood. Recently, the acquired mutation JAK2 V617F has been described in the majority of patients with myeloproliferative neoplasms (MPNs).This mutation is characterized by a G to T transverse at nucleotide 1849 in exon 12 of the J...
Abstract Background & Aims:BRAF-V600E mutation has recently been considered as a molecular marker in diagnosis of Hairy Cell Leukemia (HCL). Detection of this mutation has found a diagnostic and therapeutic value. The aim of the present study was comparing the diagnostic value of BRAF V600E mutation detection with other previous methods in diagnosis of HCL patients. Materials & M...
Background: Hearing impairment as a heterogeneous disorder is the most common sensory defect that occur 1 in 1000. Mutations in GJB2 (CX26) gene at DFNB1 locus on 13q12 are responsible for autosomal recessive non-syndromic hearing loss (ARNSHL) in many populations. This study investigates the GJB2 gene mutations in deaf patients refereed to the deaf center of Tabriz. Methods: In the present ...
The marRAB operon is a regulatory locus that controls multiple drug resistance in Escherichia coli. marA encodes a positive regulator of the antibiotic resistance response, acting by altering the expression of unlinked genes. marR encodes a repressor of marRAB transcription and controls the production of MarA in response to environmental signals. A molecular and genetic study of the homologous ...
