Functional And Clinical Studies Reveal Pathophysiological Complexity Of Clcn4-Related Neurodevelopmental Condition, Elizabeth E Palmer, Linda J Richards, Et Al.

2020-Current year OA Pubs

Missense and truncating variants in the X-chromosome-linked CLCN4 gene, resulting in reduced or complete loss-of-function (LOF) of the encoded chloride/proton exchanger ClC-4, were recently demonstrated to cause a neurocognitive phenotype in both males and females. Through international clinical matchmaking and interrogation of public variant databases we assembled a database of 90 rare CLCN4 missense variants in 90 families: 41 unique and 18 recurrent variants in 49 families. For 43 families, including 22 males and 33 females, we collated detailed clinical and segregation data. To confirm causality of variants and to obtain insight into disease mechanisms, we investigated the effect on …

The Ntpase Activity Of The Double Fyve Domain-Containing Protein 1 Regulates Lipid Droplet Metabolism., Victoria A. Ismail, Teri Naismith, David J. Kast

2020-Current year OA Pubs

Lipid droplets (LDs) are transient lipid storage organelles that can be readily tapped to resupply cells with energy or lipid building blocks and therefore play a central role in cellular metabolism. However, the molecular factors and underlying mechanisms that regulate the growth and degradation of LDs are poorly understood. It has emerged that proteins that establish contacts between LDs and the endoplasmic reticulum play a critical role in regulating LD metabolism. Recently, the autophagy-related protein, double FYVE domain-containing protein 1 (DFCP1/ZFYVE1) was shown to reside at the interface of the endoplasmic reticulum and LDs, however, little is known about the …

Research Collection School of Social Sciences

The COVID-19 pandemic has disrupted the lives of many. In particular, during the height of the pandemic, many experienced lockdowns, which in turn increased screen time drastically. While the pandemic has been declared an endemic and most activities have been reinstated, there appears to still be elevated screen time among adolescents due to poor habits formed during the pandemic lockdowns. This paper explores the factors by which screen time affects well-being among adolescents and how the pandemic may have influenced some of these factors. For example, beyond having greater screen time, many adolescents have also reduced their physical activities and …

Efficient Approach For Solving (2+1) D- Differential Equations, Luma N. M. Tawfiq, Noor A. Hussein

Baghdad Science Journal

In this article, a new efficient approach is presented to solve a type of partial differential equations, such (2+1)-dimensional differential equations non-linear, and nonhomogeneous. The procedure of the new approach is suggested to solve important types of differential equations and get accurate analytic solutions i.e., exact solutions. The effectiveness of the suggested approach based on its properties compared with other approaches has been used to solve this type of differential equations such as the Adomain decomposition method, homotopy perturbation method, homotopy analysis method, and variation iteration method. The advantage of the present method has been illustrated by some examples.

Reducing The Risk Of Mortality In Chronic Obstructive Pulmonary Disease With Pharmacotherapy: A Narrative Review, Matthew Mintz, Igor Barjaktarevic, Donald A. Mahler, Barry Make, Neil Skolnik, Barbara Yawn, Bree Zeyzus-Johns, Nicola A. Hanania

Abington Jefferson Health Papers

In 2020, chronic obstructive pulmonary disease (COPD) was the fifth leading cause of death in the United States excluding COVID-19, and its mortality burden has been rising since the 1980s. Smoking cessation, long-term oxygen therapy, noninvasive ventilation, and lung volume reduction surgery have had a beneficial effect on mortality; however, until recently, the effects of pharmacologic therapies on all-cause mortality have been unclear. Inhaled pharmacologic treatments for patients with COPD include combinations of long-acting muscarinic receptor antagonists (LAMAs), long-acting-β2-agonists (LABAs), and inhaled corticosteroids (ICS). The recent IMPACT and ETHOS clinical trials reported mortality benefits with ICS/LAMA/LABA triple therapy compared with …

Cryptocurrencies And Climate Change: A Net-Zero Paradox, Jason Maclean

Canadian Journal of Law and Technology

Cryptocurrencies pose a number of complex law and policy problems, the most pressing of which are the industry’s climate and environmental impacts. This article examines the climate and environmental impacts of crypto-assets in the broader law and policy context of the UN Paris Agreement and the global goal of reaching net-zero emissions by 2050 or earlier. This approach not only illuminates the limitations and paradoxical nature of the crypto-industry’s climate commitments, but also the limitations and paradoxical nature of ‘‘net zero” itself as the predominant framing of national, subnational, and nonstate actors’ climate pledges. The article concludes by examining the …

These vaccines are claimed in myriad – not Myriad – patents and patent applications, many of which are destined to be litigated over the coming years, not least inspired by the many billions of dollars that have been, and will continue to be, earned by their owners. While the world waits for this storm of patent litigation, federal courts continue to be busy with ownership, licensing, …

Estimating The Demand For Groundwater: A Second-Stage Hedonic Land Price Analysis For The Lower Mississippi River Alluvial Plain, Arkansas, Kent Kovacs, Sheby Rider

Agricultural Economics and Agribusiness Faculty Publications and Presentations

We estimate the benefits of the saturated thickness (water-bearing porous material) of the alluvial aquifer in Arkansas through an application of the hedonic price model to the sale of agricultural land. There is evidence from the first-stage analysis of diminishing returns from increasing saturated thickness. Using a survey of farmer operators’ preferences and socioeconomic characteristics, we recover the underlying demand function for saturated thickness in a second-stage analysis. Shifts in the demand function reveal that produced/social capital can be a substitute or a complement to saturated thickness, and human capital is a substitute for saturated thickness.

Combinatorial Identities Associated With A Bivariate Generating Function For Overpartition Pairs, Atul Dixit, Ankush Goswami

School of Mathematical & Statistical Sciences Faculty Publications

We obtain a three-parameter q-series identity that generalizes two results of Chan and Mao. By specializing our identity, we derive new results of combinatorial significance in connection with N(r,s,m,n), a function counting certain overpartition pairs recently introduced by Bringmann, Lovejoy and Osburn. For example, one of our identities gives a closed-form evaluation of a double series in terms of Chebyshev polynomials of the second kind, thereby resulting in an analogue of Euler's pentagonal number theorem. Another of our results expresses a multi-sum involving N(r,s,m,n) in terms of just the partition function p(n). Using a result of Shimura we also relate …

Coloring Complexes And Combinatorial Hopf Monoids, Jacob A. White

School of Mathematical & Statistical Sciences Faculty Publications

We generalize the notion of a coloring complex of a graph to linearized combinatorial Hopf monoids. We determine when a linearized combinatorial Hopf monoid has such a construction, and discover some inequalities that are satisfied by the quasisymmetric function invariants associated to the combinatorial Hopf monoid. We show that the collection of all such coloring complexes forms a linearized combinatorial Hopf monoid, which is the terminal object in the category of combinatorial Hopf monoids with convex characters. We also study several examples of combinatorial Hopf monoids.
