A Remarkable Difference in Pharmacokinetics of Fluorinated Versus Iodinated Photosensitizers Derived from Chlorophyll-a and a Direct Correlation between the Tumor Uptake and Anti-Cancer Activity (open access)

A Remarkable Difference in Pharmacokinetics of Fluorinated Versus Iodinated Photosensitizers Derived from Chlorophyll-a and a Direct Correlation between the Tumor Uptake and Anti-Cancer Activity

Article says that to investigate and compare the pharmacokinetic profile and anti-cancer activity of fluorinated and iodinated photosensitizers (PSs), the 3-(1′-(o-fluorobenzyloxy)ethyl pyropheophorbide and the corresponding meta-(m-) and para (p-) fluorinated analogs (methyl esters and carboxylic acids) were synthesized. According to the authors, the nature of the delivery vehicle and tumor types showed a significant difference in uptake and long-term cure by photodynamic therapy (PDT), especially in the iodinated PS.

Biocultural Calendars Across Four Ethnolinguistic Communities in Southwestern South America (open access)

Biocultural Calendars Across Four Ethnolinguistic Communities in Southwestern South America

Article describes how, since the mid-20th century, the so-called Great Acceleration has amplified processes of ecosystem degradation, extinction of biological species, displacement of local peoples, losses of languages, and cultural diversity. The authors examine cultural practices and socio-environmental changes across four contrasting ethnolinguistic communities in southwestern South America, from southern to northern Chile along a marked climatic gradient to show the broad application of the concept of biocultural calendars.

Shedding New Light on Weak Emission-Line Quasars in the CIV-Hβ Parameter Space (open access)

Shedding New Light on Weak Emission-Line Quasars in the CIV-Hβ Parameter Space

Article describes how weak emission-line quasars (WLQs) are a subset of Type 1 quasars that exhibit extremely weak Lyα+N V λ1240 and/or C IV λ1549 emission lines. The authors investigate the relationship between emission-line properties and accretion rate for a sample of 230 `ordinary' Type 1 quasars and 18 WLQs at z<0.5 and 1.5<z<3.5 that have rest-frame ultraviolet and optical spectral measurements.

Exposure to diesel exhaust particulates and desert sand dust generates microvesicle particles and platelet-activating factor agonists (open access)

Exposure to diesel exhaust particulates and desert sand dust generates microvesicle particles and platelet-activating factor agonists

The authors address the editor in their article, stating that the majority of the general population, particularly, servicemen and women deployed across the globe are exposed to various airborne hazards, including diesel exhaust particulate (DEP) and desert sand dust (DSD). Studies, including the author's study, have shown that exposure to ROS-generating pro-oxidative stressors ranging from environmental carcinogens to pollutants, including cigarette smoke, produces a class of potent phospholipid mediators, Platelet-activating factor (PAF) and PAF-like agonists via oxidative cleavage of lipid membrane glycerophosphocholines (GPCs).

Thyroid hormone manipulation influences development of endothermy and hatching in white leghorn chickens (Gallus gallus)

Data collected on metabolic rates, body temperatures, morphology, plasma T3, and hatching of developing chicken embryos and hatchlings. To understand the role thyroid hormones play in hatch timing and development of thermogenic capacity and metabolic rate plasma thyroid hormone levels were manipulated in chicken embryos beginning at 80% development (day 17 of a 21-day incubation) with either a single dose of triiodo-L-thyronine (T3) or the thyroperoxidase inhibitor methimazole (MMI).

The Fractal Tapestry of Life: III Multifractals Entail the Fractional Calculus

This article is the third essay advocating the use the (non-integer) fractional calculus (FC) to capture the dynamics of complex networks in the twilight of the Newtonian era. Herein, the focus is on drawing a distinction between networks described by monfractal time series extensively discussed in the prequels and how they differ in function from multifractal time series, using physiological phenomena as exemplars.

Using uncertainty quantification and machine learning techniques to study the evolution of odor capture (open access)

Using uncertainty quantification and machine learning techniques to study the evolution of odor capture

Data management plan for the research grant, "Using uncertainty quantification and machine learning techniques to study the evolution of odor capture." This research proposes the application of uncertainty quantification (UQ) and machine learning (ML) to a CFD model of odor capture to understand the role of hair-array morphology, kinematics, and fluid environment in odor capture. The combination of CFD modeling and UQ&ML techniques can map out the performance space under which these chemosensory hair arrays operate and the relative sensitivity of each parameter of odor capture to construct a global, quantitative understanding of how parameters control odor-capture performance. Furthermore, this analysis can eliminate parameters that have no influence on odor capture, extracting the root principles of odor capture and providing a more efficient way to construct bioinspired devices for chemical detection. This work is of interest to the Army for extracting design principles that can be used for biomimetic and/or bioinspired devices for sensing hazardous chemicals in the environment (e.g. explosives).
