The use of cardioprotective strategies as adjuvants of cardioplegic solutions has become an ideal alternative for the improvement of post-surgery heart recovery. The choice of the optimal cardioplegia, as well as its distribution mechanism, remains controversial in the field of cardiovascular surgery. There is still a need to search for new and better cardioprotective methods during cardioplegic procedures. New techniques for the management of cardiovascular complications during cardioplegia have evolved with new alternatives and additives, and each new strategy provides a tool to neutralize the damage after ischemia/reperfusion events. Researchers and clinicians have committed themselves to studying the effect of …

In this study, we identified three novel compound classes with potent activity against Plasmodium falciparum, the most dangerous human malarial parasite. Resistance of this pathogen to known drugs is increasing, and compounds with different modes of action are urgently needed. One promising drug target is the enzyme 1-deoxy-D-xylulose-5- phosphate synthase (DXPS) of the methylerythritol 4-phosphate (MEP) pathway for which we have previously identified three active compound classes against Mycobacterium tuberculosis. The close structural similarities of the active sites of the DXPS enzymes of P. falciparum and M. tuberculosis prompted investigation of their antiparasitic action, all classes …

A Survey Of Fusarium Oxysporum In Georgia Hemp Farms And Vegetable Gardens, Christopher D. Burt
A Survey Of Fusarium Oxysporum In Georgia Hemp Farms And Vegetable Gardens, Christopher D. Burt
Georgia Journal of Science
Recent changes in U.S. federal law have recognized the genetic and chemical differences between hemp and marijuana (Cannabis sativa L.), resulting in the legalization of hemp in the United States. The barriers to this plant’s growth in the state of Georgia are not well understood due to its prohibition for the past 80 years. Among the many possible obstacles is fungal disease. Fusarium oxysporum (Schlecht. emend. Snyder & Hansen) is a fungus that damages various crops and was previously researched as a biocontrol agent for C. sativa. Thus, this study surveyed hemp farms in Georgia to determine the prevalence …
Xun Zi On Desiring To Be Good: Desire As The Necessary Condition For The Transformation Of Nature, Angel Ting
Xun Zi On Desiring To Be Good: Desire As The Necessary Condition For The Transformation Of Nature, Angel Ting
Comparative Philosophy
There are various discussions on the role of desires in the Xun-Zi and how the transformation of nature takes place. Some scholars hold that the heart-mind can override inborn human desires, a view that is analogous to externalism; others maintain the internalism view that desires are essentially motivating in the Xun-Zi. This paper aims to resolve this seeming conflict between externalism and internalism. By introducing David B. Wong's model of being an internalist about duty and an externalist about reason, I will show that desires in the Xun-Zi are necessarily motivating because of their direction of fit, and …
A Madhyamaka Critique Of Jaegwon Kim's Supervenience Argument, Tyler J. Jungbauer
A Madhyamaka Critique Of Jaegwon Kim's Supervenience Argument, Tyler J. Jungbauer
Comparative Philosophy
Jaegwon Kim’s supervenience argument objects to the possibility of emergent causation (both downward and same-level) based on both (1) the causal overdetermination of both (a) higher-level emergent events and (b) lower-level basal events, and (2) the causal closure principle of the physical domain. Kim argues that emergent causation entails epiphenomenalism. Madhyamaka Buddhist philosophy skeptically critiques the primary (ultimate) existence of causal phenomena and instead suggests that all such phenomena may only be secondarily (conventionally) existent. Mādhyamikas acknowledge that, conventionally, emergent phenomena appear to cause both basal phenomena and other emergent phenomena. However, contra Kim, Mādhyamikas doubt that causal relations ultimately …
Sustainable Futures-Integrating Indigenous Perspectives Into An Environmental Assessment Framework: An Analysis Of The Mauri Model, Anna Bettini
Journal of Environmental Sustainability
The twin concepts of sustainable development and sustainability have been key points in new policies. Nonetheless, only the Western scientific perspective is typically considered, excluding other voices and leading to a very narrow vision of “sustainability”. The following article investigates the benefits to including indigenous knowledge and principles, considering their values rather than limitations and presents two specific case studies using the Mauri Model Decision Making Framework, a tool applied for environmental assessment, seen as a more cultural-friendly sustainable approach.

The inherited disease community in Sri Lanka has been widely neglected. This article aimed to present accumulated knowledge in establishing a pro bono cost-effective national, island-wide, free-of-charge molecular diagnostic service, suggesting a model for other developing countries. The project provided 637 molecular diagnostic tests and reports free of charge to a nation with limited resources. We pioneered the implementation of mobile clinics and home visits, where the research team acted as barefoot doctors with the concept of the doctor and the researcher at the patient’s doorstep. Establishing pro bono, cost-effective molecular diagnostics is feasible in developing countries with limited resources …
Soybean Arogenate Dehydratases (Gmadts): Involvement In The Cytosolic Isoflavonoid Metabolon Or Trans-Organelle Continuity?, Emily J. Clayton, Nishat S. Islam, Kelsey Pannunzio, Kuflom Kuflu, Ramtin Sirjani, Susanne E. Kohalmi, Sangeeta Dhaubhadel
Soybean Arogenate Dehydratases (Gmadts): Involvement In The Cytosolic Isoflavonoid Metabolon Or Trans-Organelle Continuity?, Emily J. Clayton, Nishat S. Islam, Kelsey Pannunzio, Kuflom Kuflu, Ramtin Sirjani, Susanne E. Kohalmi, Sangeeta Dhaubhadel
Biology Publications
Soybean (Glycine max) produces a class of phenylalanine (Phe) derived specialized metabolites, isoflavonoids. Isoflavonoids are unique to legumes and are involved in defense responses in planta, and they are also necessary for nodule formation with nitrogen-fixing bacteria. Since Phe is a precursor of isoflavonoids, it stands to reason that the synthesis of Phe is coordinated with isoflavonoid production. Two putative AROGENATE DEHYDRATASE (ADT) isoforms were previously co-purified with the soybean isoflavonoid metabolon anchor ISOFLAVONE SYNTHASE2 (GmIFS2), however the GmADT family had not been characterized. Here, we present the identification of the nine member GmADT family. We determined that the GmADTs …

Aspen And Spruce Densities Affect Tree Size, Future Stand Volume, And Aboveground Carbon Following Precommercial Thinning, Philip G. Comeau, Mike Bokalo
Aspen Bibliography
Data collected over a 30-year period from an experiment replicated across 21 locations in western Canada are used to explore the effects of precommercial thinning of trembling aspen to a range of densities in combination with three initial white spruce densities on tree growth and stand dynamics. Increasing differentiation amongst the 15 treatments was observed with age after thinning for both spruce and aspen responses. Spruce height and diameter declined with increasing aspen density. At age 10 spruce diameter with no aspen was 1.5× that of spruce in unthinned while it was 2.6× that of spruce in unthinned at age …

Aquaculture is crucial for global food and nutrition security due to the inability of wild harvests to meet increasing demand. Africa’s contribution to aquaculture is generally low, despite its potential for economic development, food security, and reduced unemployment. The study focuses on the African catfish (Clarias gariepinus) a freshwater fish species that is widely farmed for food in Africa and other parts of the world. Proper nutrition is essential for the growth and development of the fish, and understanding their nutritional requirements is critical for producing healthy and high-quality fish. This review article provides an overview of the knowledge on …

“There’S So Much History”: Shared Parenting Dynamics In Kinship Families, Amanda Klein-Cox, Angela Tobin, Ramona Denby
Social Work Faculty Research
Shared parenting, when adults collaborate in childrearing, is a practice of interest for children in out-of-home care. Yet, little is known about its feasibility and outcomes for kinship families who have preexisting relationships with birth parents. This article shares qualitative results from focus groups that explored participants’ experiences and attitudes toward shared parenting. The sample comprised 25 kinship caregivers and 34 child welfare professionals. Findings revealed that shared parenting within kinship families is often less feasible than desired. This article identifies barriers and facilitators of shared parenting, offers a shared parenting typology, and explores implications for policy and practice.

Tracing The Maternal Line In Glacial-Interglacial Migrations Of Populus Tremuloides: Finding Trees For Future Sustainable Forests By Searching In The Past, Luke R. Tembrock, Frida A. Zink, Guozhe Zhang, Andrea Schuhmann, Cuihua Gu, Zhiqiang Wu
Aspen Bibliography
Maintaining and planting sustainable forests is fundamental in perpetuating the essential functions of these ecosystems. A central aspect of managing forests for future resilience is the consideration of past migration and evolution of trees using genetic and genomic data to ensure that functionally appropriate diversity is conserved and utilized. In our study, we generated and compared genetic and genomic data from the plastome to better understand phylogeography and molecular evolution in the tree species Populus tremuloides (aspen). With these analyses, we found evidence of divergence and migration between northern and southern sites. Additionally, evidence of deep incomplete plastome sorting across …

A method of modulating neural activity using a combination of electrical and optical stimulation transmitted via a gold nanoparticle covered nanoelectrode is presented. The combination of short-duration green visible light optical pulses with the complementary sub-threshold level electric current pulses are capable of producing action potentials in neurons. Cells were found to have a greater than a 5Ã survival rate using this hybrid stimulation method as compared to pure plasmonic/optical stimulation. The cell stimulation success rate was 3Ã greater with hybrid stimulation.

Targeting Efferocytosis In Inflammaging, Ivan K H Poon, Kodi S Ravichandran
2020-Current year OA Pubs
Rapid removal of apoptotic cells by phagocytes, a process known as efferocytosis, is key for the maintenance of tissue homeostasis, the resolution of inflammation, and tissue repair. However, impaired efferocytosis can result in the accumulation of apoptotic cells, subsequently triggering sterile inflammation through the release of endogenous factors such as DNA and nuclear proteins from membrane permeabilized dying cells. Here, we review the molecular basis of the three key phases of efferocytosis, that is, the detection, uptake, and degradation of apoptotic materials by phagocytes. We also discuss how defects in efferocytosis due to the alteration of phagocytes and dying cells …

We evaluated whether inhibiting sterile alpha and (Toll/interleukin receptor (TIR)) motif-containing 1 (SARM1) activity protects retinal ganglion cells (RGCs) following ischemic axonopathy (rodent nonarteritic anterior ischemic optic neuropathy: rNAION) by itself and combined with ciliary neurotrophic factor (CNTF). Genetically modified SARM1(-) rats were rNAION-induced in one eye and compared against equivalently induced wild-type animals of the same background. Optic nerve (ON) diameters were quantified using optical coherence tomography (SD-OCT). RGCs were quantified 30 d post-induction using retinal stereology for Brn3a(+) nuclei. ON sections were analyzed by TEM and immunohistochemistry. SARM1(-)(-) and WT animals were then bilaterally sequentially rNAION-induced. One eye …

BACKGROUNDSepsis remains a major clinical challenge for which successful treatment requires greater precision in identifying patients at increased risk of adverse outcomes requiring different therapeutic approaches. Predicting clinical outcomes and immunological endotyping of septic patients generally relies on using blood protein or mRNA biomarkers, or static cell phenotyping. Here, we sought to determine whether functional immune responsiveness would yield improved precision.METHODSAn ex vivo whole-blood enzyme-linked immunosorbent spot (ELISpot) assay for cellular production of interferon γ (IFN-γ) was evaluated in 107 septic and 68 nonseptic patients from 5 academic health centers using blood samples collected on days 1, 4, and 7 …

Suppression of glucagon hypersecretion can normalize hyperglycemia during type 1 diabetes (T1D). Activating erythropoietin-producing human hepatocellular receptor type-A4 (EphA4) on α cells reduced glucagon hypersecretion from dispersed α cells and T1D islets from both human donor and mouse models. We synthesized a high-affinity small molecule agonist for the EphA4 receptor, WCDD301, which showed robust plasma and liver microsome metabolic stability in both mouse and human preparations. In islets and dispersed islet cells from nondiabetic and T1D human donors, WCDD301 reduced glucagon secretion comparable to the natural EphA4 ligand, Ephrin-A5. In diabetic NOD and streptozotocin-treated mice, once-daily oral administration of WCDD301 …

Circadian rhythm dysfunction is a hallmark of Parkinson disease (PD), and diminished expression of the core clock gene Bmal1 has been described in patients with PD. BMAL1 is required for core circadian clock function but also serves nonrhythmic functions. Germline Bmal1 deletion can cause brain oxidative stress and synapse loss in mice, and it can exacerbate dopaminergic neurodegeneration in response to the toxin MPTP. Here we examined the effect of cell type-specific Bmal1 deletion on dopaminergic neuron viability in vivo. We observed that global, postnatal deletion of Bmal1 caused spontaneous loss of tyrosine hydroxylase+ (TH+) dopaminergic neurons in the substantia …

Ischemia/reperfusion injury-mediated (IRI-mediated) primary graft dysfunction (PGD) adversely affects both short- and long-term outcomes after lung transplantation, a procedure that remains the only treatment option for patients suffering from end-stage respiratory failure. While B cells are known to regulate adaptive immune responses, their role in lung IRI is not well understood. Here, we demonstrated by intravital imaging that B cells are rapidly recruited to injured lungs, where they extravasate into the parenchyma. Using hilar clamping and transplant models, we observed that lung-infiltrating B cells produce the monocyte chemokine CCL7 in a TLR4-TRIF-dependent fashion, a critical step contributing to classical monocyte …
