This research addresses interaction mechanisms of water-soluble polymers used as soil mineral stabilizers via atomistic classical molecular dynamics (MD). Specifically, this study addresses polyelectrolyte interactions with kaolinite, a ubiquitous clay mineral, in soils. The two water-soluble polymeric species evaluated are PSS: poly(4-sodium styrenesulfonate) and PDADMAC: poly(diallyldimethylammonium chloride).

Exclusionary Effects of Campsite Allocation through Reservations in U.S. National Parks: Evidence from Mobile Device Location Data.

Campsites represent highly sought after recreational amenities in the national parks of the United States. Equitable allocation of scarce recreational resources has long been a key management issue in U.S.

Relation between microscopic structure and macroscopic properties in polyacrylonitrile-based lithium-ion polymer gel electrolytes.

Polymer gel electrolytes (PGE) have seen a renewed interest in their development because they have high ionic conductivities but low electrochemical degradation and flammability. PGEs are formed by mixing a liquid lithium-ion electrolyte with a polymer at a sufficiently large concentration to form a gel. PGEs have been extensively studied, but the direct connection between their microscopic structure and macroscopic properties remains controversial.

The ART of cryopreservation and its changing landscape.

The purpose of this review is to educate the reader on the role that cryopreservation has played and continues to play in the ever-evolving field of assisted reproductive technologies, specifically in clinical human fertility treatment. We discuss the science behind the cryopreservation methods and investigated some of the major considerations that any clinic or cryobank faces in terms of risks and liabilities, physical challenges that accompany the constantly growing collection of cryopreserved specimens, and what this means on the ethical and legal front. Finally, we take a glimpse in the future to explore what may be on the horizon for the preservation of gametes and reproductive tissues.

Tale of a "Non-interacting" Additive in a Lithium-Ion Electrolyte: Effect on Ionic Speciation and Electrochemical Properties.

New lithium electrolytes compatible with high energy density cells are critical for lithium metal battery applications, but dendrite formation associated with the use of dilute organic electrolytes complicates their realization. High-concentration electrolytes mitigate some of the issues of the electrolytes but introduce additional problems, such as low conductivity and high cost. Hence, pseudo-concentrated electrolytes, wherein a co-solvent is added to a dilute electrolyte, have been presented as a possible alternative to both dilute and concentrated electrolytes.

Pathophysiology and management of classic galactosemic primary ovarian insufficiency.

Unlabelled: Classic galactosemia is an inborn error of carbohydrate metabolism associated with early-onset primary ovarian insufficiency (POI) in young women. Our understanding of the consequences of galactosemia upon fertility and fecundity of affected women is expanding, but there are important remaining gaps in our knowledge and tools for its management, and a need for continued dialog so that the special features of the condition can be better managed. Here, we review galactosemic POI and its reproductive endocrinological clinical sequelae and summarize current best clinical practices for its management.

Active Music Therapy Following Acute Stroke: A Single-Arm Repeated Measures Study.

Experiencing a stroke can lead to difficulties with emotion regulation and mood disorders like depression. It is well documented that poststroke depression (PSD) affects a third of all stroke survivors. Higher levels of depression and depressive symptoms are associated with less efficient use of rehabilitation services, poor functional outcomes, negative impacts on social participation, and increased mortality.

Structural and dynamical changes observed when transitioning from an ionic liquid to a deep eutectic solvent.

The microscopic molecular structure and dynamics of a new deep eutectic solvent (DES) composed of an ionic liquid (1-hexyl-3-methylimidazolium chloride) and an amide (trifluoroacetamide) at various molar ratios were investigated using linear and non-linear infrared spectroscopy with a vibrational probe. The use of the ionic liquid allows us to investigate the changes that the system undergoes with the addition of the amide or, equivalently, the changes from an ionic liquid to a DES. Our studies revealed that the vibrational probe in the DES senses a very similar local environment irrespective of the cation chemical structure.

Fertility Issues in Polycystic Ovarian Disease: A Systematic Approach.

The triad of hirsutism, amenorrhea, and enlarged polycystic ovaries first was described in 1935 and later become known as polycystic ovarian syndrome (PCOS). Women with PCOS are more likely to have cardiometabolic challenges that also have an indirect relationship to their fertility and fertility outcomes. Despite these challenges, their fertile life span appears to be longer.

Ovarian stimulation for fertility preservation in an oncology patient with etonogestrel implant in place.

Purpose: To describe a case of a young woman who presented for fertility preservation and underwent ovarian stimulation with an etonogestrel implant in place.

Methods: A 24-year old, gravida 0, with an etonogestrel implant and newly diagnosed lower extremity sarcoma and DVT desiring oocyte cryopreservation prior to adjuvant chemotherapy and radiation. To avoid delay in her oncologic care and allow for continued use of contraception post-retrieval, the patient underwent controlled ovarian hyperstimulation (COH) without removal of the etonogestrel implant.

Molecularly Heterogeneous Structure of a Nonionic Deep Eutectic Solvent Composed of N-Methylacetamide and Lauric Acid.

Deep eutectic solvents (DES) are a new class of designer solvents with a wide range of possible applications. DESs are typically made from an ionic compound and a hydrogen bond donor, but lately DESs made of nonionic compounds with interesting properties have started to appear. This study focuses on describing the structure, dynamics, and interactions of a nonionic DES composed of  N-methylacetamide (NMA) and lauric acid (LA).

Delivery of the research participant perception survey through the patient portal.

Introduction: The patient portal may be an effective method for administering surveys regarding participant research experiences but has not been systematically studied.

Methods: We evaluated 4 methods of delivering a research participant perception survey: mailing, phone, email, and patient portal. Participants of research studies were identified (n=4013) and 800 were randomly selected to receive a survey, 200 for each method.

Novel treatment avenues for uterine leiomyoma: a new implication for endothelin?

Cysteine-rich angiogenic inducer 61 (CYR61), an angiogenic factor whose expression is decreased in fibroids. The aim of the present study was to determine if CYR61 secretion in smooth muscle cells (SMCs) is regulated by hypoxia and through the endothelin A (ET) receptor. SMCs from fibroids (fSMC) and the adjacent myometrium smooth muscle cells (mSMCs) were extracted from ten women undergoing hysterectomy for uterine fibroids and cultured with or without 1.

Effects of Religious Involvement on HIV Management Outcomes Among HIV-Positive Adults in Central North Carolina.

Objectives: The goals of this pilot cross-sectional study were to determine the feasibility of and begin measuring the effect of religious institution affiliation on human immunodeficiency virus (HIV) clinical outcomes in the southern United States, a region marked by later initiation of antiretroviral therapy, higher HIV-related morbidity, and higher mortality rates than people living with HIV (PLWH) elsewhere in the country. It also is a region with a high density of religious institutions, which may facilitate improved health outcomes through leveraged social capital. Because spirituality is a personal construct and PLWH constitute a vulnerable population, we wanted to determine whether it would be feasible to survey patients about the topic.

Clinical Characteristics and Health Outcomes of Neonates Reporting to the Emergency Department With Hypothermia.

Objectives: Although hypothermia has long been considered a sign of serious bacterial infection (SBI) in neonates, there is a lack of medical literature on this topic, and little is known about the prevalence of serious infection in these patients. Our primary objective was to assess the prevalence and type of serious infection in neonates with hypothermia. Our secondary objective was to describe the prevalence and type of significant pathology overall in this cohort.
