We have investigated the effects in vitro of a series bisphosphonates on proliferation Trypanosoma cruzi, brucei rhodesiense, Leishmania donovani, Toxoplasma gondii, and Plasmodium falciparum. The results show that nitrogen-containing type used bone resorption therapy significant activity against parasites, with aromatic species having some cases nanomolar or low-micromolar IC50 values parasite replication (e.g. o-risedronate, = 220 nM for T. rhodesiense; risedronate, 490 gondii). In...
As a continuation of our project aimed at the search for new and safe chemotherapeutic chemoprophylactic agents against American trypanosomiasis (Chagas' disease), several drugs structurally related to 4-phenoxyphenoxyethyl thiocyanate (4) were designed, synthesized, evaluated as antiproliferative parasite responsible this disease, hemoflagellated protozoan Trypanosoma cruzi. This derivative was previously shown be an effective potent agent T. cruzi proliferation. Several possessing groups...
High field <sup>31</sup>P nuclear magnetic resonance spectroscopy showed that inorganic pyrophosphate (P<sub>2</sub>O<sub>7</sub><sup>4−</sup>) is more abundant than ATP in <i>Trypanosoma cruzi</i>, the causative agents of Chagas' disease. These results were confirmed by specific analytical assays, which epimastigotes, concentrations and 194.7 ± 25.9 37.6 5.5 nmol/mg protein, respectively, for amastigote form, corresponding 358.0 17.0 36.0 1.9 protein. performance liquid chromatographic...

In this paper we used simulation tools to study turbulent boundary-layer structures in the roughness sublayer. Of particular interest is case of a neutrally-stratified atmospheric boundary layer which lower covered by homogeneous plant canopy. The goal was formulate consistent conceptual model for creation and evolution dominant coherent associated with canopy how they link features observed overlying inertial First, were examined using temporally developing flow where full range scales had...
This article presents an overview of Helios, a new three-dimensional (3D) plant and environmental modeling framework. Helios is model coupling framework designed to provide maximum flexibility in integrating running arbitrary 3D system models. Users interact with through well-documented open-source C++ API. Version 1.0 comes plug-ins for radiation transport, the surface energy balance, stomatal conductance, photosynthesis, solar position, procedural tree generation. Additional are also...
The addition of PPi promoted the acidification a subcellular compartment in cell homogenates Toxoplasma gondii tachyzoites, implying presence proton-translocating pyrophosphatase. proton gradient was collapsed by K+/H+ antiporter nigericin, and also inhibited analogue aminomethylenediphosphonate (AMDP). Both transport hydrolysis were dependent upon K+, but Na+ caused partial inhibition these activities. sensitive dose-dependent manner to AMDP, imidodiphosphate, NaF thiol reagent...

As a part of our project directed at the search new chemotherapeutic agents against American trypanosomiasis (Chagas' disease), several drugs possessing 4-phenoxyphenoxy skeleton and other closely related structures employing thiocyanate moiety as polar end group were designed, synthesized, evaluated antiproliferative Trypanosoma cruzi, parasite responsible for this disease. These analogues envisioned bearing in mind potent activity shown by 4-phenoxyphenoxyethyl (compound 8) taken lead...
A microscale wildfire model, QES-Fire, that dynamically couples the fire front to winds was developed using a simplified physics rate of spread (ROS) kinematic plume-rise model and mass-consistent wind solver. The is three-dimensional heat fluxes field while being more computationally efficient than other coupled models. calculates potential velocity scaled by ROS model’s flux. Distinct plumes are merged multiscale plume-merging methodology can efficiently represent complex fronts. plume...
Stomatal conductance ( g s ) is a crucial component of plant physiology, as it links productivity and water loss through transpiration. Estimating indirectly leaf temperature T l measurement common for reducing the high labor cost associated with direct measurement. However, relationship between observed can be notably affected by local environmental conditions, canopy structure, scale, sample size, itself. To better understand quantify variation in measurements to , this study analyzed...
Deep learning and multimodal remote proximal sensing are widely used for analyzing plant crop traits, but many of these deep models supervised necessitate reference datasets with image annotations. Acquiring often demands experiments that both labor-intensive time-consuming. Furthermore, extracting traits from data beyond simple geometric features remains a challenge. To address challenges, we proposed radiative transfer modeling framework based on the Helios 3-dimensional (3D) software...
