We present observations and experimental results supporting the view that macroalgal morphology can represent a balance between maximizing photosynthetic ability limiting susceptibility of thallus to mechanical damage. The relationships among morphology, water flow, photosynthesis were examined for five algal species representing three functional forms marine macroalgae at Santa Catalina Island, California, USA. relationship surface area/volume ratio (SA/V) rates biomass-specific net (NP)...

To determine the relative importance of different sources nitrate to annual nitrogen needs giant kelp Macrocystis pyrifera , we measured ambient concentrations at a forest for 13 months and characterized delivery using water column thermal structure flow data collected in its offshore edge. The forest's monthly supply varied by factor 50, while net acquisition only fivefold. Maximum rates fronds interior were 0.18 mmol N g −1 month during spring upwelling 2005 declined fourfold autumn until...

Turbinaria ornata (Turner) J. Agardh is a tropical alga that disperses by detached, reproductively mature floating fronds. Material properties (breaking stress, breaking extension), buoyancy, and the proportion of reproductive tissue per frond were measured for juvenile, adult, old fronds T . Correlations between these factors indicate as age become more mature, in their stipes (where they break) becomes weaker, brittle, overall buoyancy increases. Measurement drag force experienced from...

An upright posture in the water column may expose benthic marine organisms to faster flow higher than near substratum, potentially increasing rates of mass exchange while also exposing hydrodynamic forces. Benthic maintain postures by one two mechanisms, stiffness or buoyancy. Turbinaria ornata is a tropical macroalga that uses either buoyancy flexural (EI), depending on its habitat. This study used physical models T. compare effect different magnitudes these mechanisms relative velocity and...

NF-κB-inducing kinase (NIK) is a key enzyme in the noncanonical NF-κB pathway, of interest treatment variety diseases including cancer. Validation NIK as drug target requires potent and selective inhibitors. The protein contains cysteine residue at position 444 back pocket active site, unique within kinome. Analysis existing inhibitor scaffolds early structure–activity relationships (SARs) led to design C444-targeting covalent inhibitors based on alkynyl heterocycle warheads. Mass...

Like many reefs worldwide, in French Polynesia are experiencing a shift from coral-dominated to algal-dominated systems. The macroalga Turbinaria ornata comprises the majority of increasing algal biomass on barrier surrounding these islands, and its distribution is throughout this region. Aspects ecomorphology make it ideally suited thrive under physical conditions found across Polynesia. Spatial morphological variation allows produce morphotypes that either calm, unidirectional, slowly...

This work was motivated by subtidal observations of red urchins (Strongylocentrotus franciscanus) moving their spines into streamlined positions as water current increased in the field. Trials a flume across flow speeds from 0 to 65 cm s(-1) enabled us observe change overall shape and quantify decrease spine angle that occurred increased. The effect this behaviour on drag lift measured with physical models made urchin tests `up' position (typical stagnant slow velocities) `down' posture high...

Ureas are an important functional group in small molecule drugs as well having wider applications organic chemistry. Understanding of their conformation is critical importance for rational design urea-containing bioactive compounds. Whilst the conformational preferences biaryl ureas have been extensively studied, very little attention has paid to alkylated analogues. We carried out a systematic study N-aryl (phenyl and pyridyl)-N'-cyclopentyl with differing N-methylation patterns using Well...

High-throughput screening provides one of the most common ways finding hit compounds. Lead-like libraries, in particular, provide hits with compatible functional groups and vectors for structural elaboration physical properties suitable optimization. Library synthesis approaches can lead to a lack chemical diversity because they employ parallel derivatization building blocks using single reaction types. We address this problem through "build-couple-transform" paradigm generation lead-like...
