ABSTRACT Constitutive biosynthesis of lipid A via the Raetz pathway is essential for the viability and fitness of Gram-negative bacteria, including Chlamydia trachomatis.Although nearly all of the enzymes in the lipid A biosynthetic pathway are highly conserved across Gram-negative bacteria, the cleavage of the pyrophosphate group of UDP-2,3-diacyl

In the activity of intervention and rescue, practical training has the primary role, thereby making it possible for rescuers to be permanently prepared to intervene in case of major incidents, accidents or events.In addition to classic training methods, namely training carried out in installations within production platforms, equipment endowment of

This paper outlines how light Unmanned Aerial Vehicles (UAV) can be used in remote sensing for precision farming.It focuses on the combination of simple digital photographic cameras with spectral filters, designed to provide multispectral images in the visible and near-infrared domains.In 2005, these instruments were fitted to powered glider and pa

A revision of the 45 species of the pantropical genus Xylopia in Tropical Africa includes descriptions of six new species and a new section of the genus.The fruits and seeds of Xylopia Canine - Treats - Frozen show specializations that promote vertebrate dispersal, primarily by hornbills and monkeys.Over half of the African species have an Area of

Acute respiratory distress syndrome (ARDS), associated with high mortality rate, affects up to 67% of hospitalized COVID-19 patients.Early evidence indicated that the pathogenesis of COVID-19 evoked ARDS is, at least partially, mediated by hyperinflammatory cytokine storm in which interleukin 6 (IL-6) plays an essential role.The corticosteroid dexa
