All Peer-Reviewed Publications

Root-knot nematodes (Meloidogyne spp.) are serious pests of most food crops, causing up to 100% yield loss. Nevertheless, commercial nematicides are costly and harmful to the environment. While the nematicidal potential of crustacean and synthetic chitin has been demonstrated globally, research on the potential of insect-derived chitin for nematode control has received limited attention. Here, seven chitin-fortified black soldier fly frass fertilizer extracts (chFE) were assessed for their suppressiveness of Meloidogyne incognita and impacts on spinach growth in comparison with a commercial nematicide using in vitro and in vivo bioassays. The performance of chFE and control treatments was assessed by …

The Effect Of Biochar From Plant Materials On Agricultural Acid Sulfate Soil: A Laboratory Incubation, Syazwan Sulaiman, Namasivayam Navaranjan, Guillermo Hernandez-Ramirez, Zohrah Sulaiman, Kathereen Liew

ASEAN Journal on Science and Technology for Development

The scarcity of suitable arable land has led to the development of acid sulfate soil for cultivation. The major problems of acid sulfate soil are the inherent low pH and available phosphorus (P) as well as the mobilization of toxic elements such as aluminium (Al) and iron (Fe), rendering the soil unfavourable for crop production. The present work aimed to evaluate the effect of biochar from plant materials on the selected parameters of acid sulfate soil in a laboratory incubation, with unamended control and dolomite treatment soils for comparison. The application of biochar significantly increased (P < 0.05) soil pH by 0.4-0.6 units as well as the soil available P by 13.1 mg kg-1 relative to the control. The soil exchangeable Al was significantly reduced (by 2.4 cmol kg-1 when compared with the control treatment. The dolomite treatment was superior relative to biochar application in increasing soil pH and decreasing Al. The dolomite application, however, was inferior to biochar treatment in increasing soil available P. Moreover, no favourable change was observed in available Fe with the applications of either biochar or lime. These results indicated that biochar has the potential for the amelioration of acid sulfate soil, especially in increasing available P. Further studies should explore the effectiveness of biochar and lime co-application in altering a wider range of soil chemical parameters to inform management options of acid sulfate soil for cultivation.

Polygenic Scores And Mendelian Randomization Identify Plasma Proteins Causally Implicated In Alzheimer’S Disease, Davis B Cammann, Yimei Lu, Jerome I Rotter, Alexis C Wood, Jingchun Chen

Faculty, Staff and Students Publications

BACKGROUND: An increasing body of evidence suggests that neuroinflammation is one of the key drivers of late-onset Alzheimer's disease (LOAD) pathology. Due to the increased permeability of the blood-brain barrier (BBB) in older adults, peripheral plasma proteins can infiltrate the central nervous system (CNS) and drive neuroinflammation through interactions with neurons and glial cells. Because these inflammatory factors are heritable, a greater understanding of their genetic relationship with LOAD could identify new biomarkers that contribute to LOAD pathology or offer protection against it.

METHODS: We used a genome-wide association study (GWAS) of 90 different plasma proteins (

RESULTS: We identified …

Effects Of Blood Flow Restriction Resistance Training On Autonomic And Endothelial Function In Persons With Parkinson's Disease, Annie Bane, Lorraine Wilson, Jill Jumper, Lindsay Spindler, Pricilla Wyatt, Darryn Willoughby

Faculty, Staff and Students Publications

Background: Autonomic dysfunction precedes endothelial dysfunction in Parkinson's disease (PD) and causes blood pressure and circulation abnormalities that are highly disruptive to one's quality of life. While exercise interventions have proven helpful for motor symptoms of PD, improving associated non-motor symptoms is limited. Low-intensity resistance training with blood flow restriction (LIRT-BFR) improves autonomic dysfunction in non-PD patients and high-intensity resistance training (HIRT) is recommended for motor symptom improvements for people with PD (PwPD).

Objective: To determine the effects of LIRT-BFR and HIRT on homocysteine and autonomic and endothelial function in PwPD and to determine the hemodynamic loads during LIRT-BFR and …
