Recognizing the roles of fever in host survival and in medical intervention in infectious diseases.

Fever has roles both in host defense against infectious challenges and in guidance of medical intervention. These roles remain insufficiently acknowledged and considered by both health care providers and patients and their families. This review cites reports in support of both roles and provides recommendations regarding the clinician's approach to fever, as well as points relevant for education of patients and their families.

Molecular Dynamics Simulations of Asphaltene Aggregation: Machine-Learning Identification of Representative Molecules, Molecular Polydispersity, and Inhibitor Performance.

Molecular dynamics simulations have been employed to investigate the effect of molecular polydispersity on the aggregation of asphaltene. To make the large combinatorial space of possible asphaltene blends accessible to a systematic study via simulation, an upfront unsupervised machine-learning approach (clustering) was employed to identify a reduced set of model molecules representative of the diversity of asphaltene. For these molecules, single asphaltene model simulations have shown a broad range of aggregation behaviors, driven by their structural features: size of the aromatic core, length of the aliphatic chains, and presence of heteroatoms.

Assessing the effect of a liquid water layer on the adsorption of hydrate anti-agglomerants using molecular simulations.

We have performed molecular dynamics simulations to study the adsorption of ten hydrate anti-agglomerants onto a mixed methane-propane sII hydrate surface covered by layers of liquid water of various thickness. As a general trend, we found that the more liquid water that is present on the hydrate surface, the less favorable the adsorption becomes even though there are considerable differences between the individual molecules, indicating that the presence and thickness of this liquid water layer are crucial parameters for anti-agglomerant adsorption studies. Additionally, we found that there exists an optimal thickness of the liquid water layer favoring hydrate growth due to the presence of both liquid water and hydrate-forming guest molecules.

Size dependence of the dissociation process of spherical hydrate particles microsecond molecular dynamics simulations.

The dissociation process of spherical sII mixed methane-propane hydrate particles in liquid hydrocarbon was investigated via microsecond-long molecular dynamics simulations. A strong dependence of the melting temperature on the particle size was found. Analysis in the context of the Gibbs-Thomson effect provided insights into the fundamental properties of gas hydrates.

Reverse Lymph Node Mapping Using Indocyanine Green Lymphography: A Step Forward in Minimizing Donor-Site Morbidity in Vascularized Lymph Node Transfer.

Background: Reverse lymphatic mapping before harvesting a lymph node flap is crucial to avoid donor-site lymphedema; however, the technique is complex and unavailable in many centers. The authors introduce radioisotope-free reverse lymphatic mapping using indocyanine green and Patent Blue dye.

Methods: The authors conducted a prospective study in patients undergoing free vascularized groin lymph node transfer for postmastectomy upper extremity lymphedema.
