The effectiveness of Biofumigants from Brassicaceae and Non-Brassicaceae to control root knot Nematodes on tomato

Habriantono Bakhroini, Wagiyana Wagiyana, Alfarisy Fariz Kustiawan · 2023 · E3S Web of Conferences

Root-knot nematodes (Meloidogyne spp.) are considered as one of the main limiting factors in crop production systems. Currently, several eco-friendly root-knot nematodes control technologies have been developed, one of which is biofumigants. The purpose of this study was to determine the effectiveness of biofumigants from Brassicaceae and Non-Brassicaceae to control root-knot nematodes. The study was conducted using a one-factor Completely Randomized Design (CRD) with 5 treatments. The results showed that the application of biofumigants from both brassicaceae and non-brassicaceae had no signif

Efficacy of Low Level Laser Therapy in Lumbar Discopathy Pain (Randomized Controlled Study)

A. Samarbakhsh, M. Shojaeei, M. Hami · 2014 · Global Spine Journal

Introduction Finding evidence based and effective method of managing low back pain (LBP) has been always a major dilemma in the field of neuromusculoskeletal system. The focus of this investigation is to establish a treatment regime for the discopathy origin of LBP using low level laser (LLL). This type of LBP is the cause of a significant number of days of sick leave in many countries. LLLT has not yet been fully adopted as a treatment method. Results of studies on LLL suggest that it reduces pain by a range of physiologic responses, such as increase in b-endorphins and depolarization blockag

Commentary on Lee & Zaryab

Olivier Senn · 2023 · Empirical Musicology Review

The study by Lee & Zaryab (this issue) investigated whether listening to high-groove music affects how heterosexual observers rate the attractiveness of people from the opposite sex. They found a very small positive effect of high-groove music on the male observers, but no effect on females. In my commentary, I argue for a more conservative interpretation of the results than the one offered by the authors.

Innovative polymer-based electrochemical platform for detecting ESAT-6 in human blood for pulmonary tuberculosis diagnosis

Xiu-An Ye, Shu-Hong Lin, Liang-Yu Chen et al. · 2025 · Sensing and Bio-Sensing Research

Pulmonary tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb), necessitates early diagnosis for effective patient care. Despite advancements in TB diagnostics, there remains an urgent need to discover innovative non-sputum-based methods to detect Mtb-specific antigens for TB patient identification. We have developed a polymer-based electrochemical biosensor for detecting an Mtb-specific antigen, the 6-kDa early secreted antigenic target (ESAT-6), in blood. Using a gold electrode (Au), the biosensor is created by electropolymerizing poly(3,4-ethylene dioxythiophene) with carboxyl grou

Impairment of retrograde neuronal transport in oxaliplatin-induced neuropathy demonstrated by molecular imaging.

Dawid Schellingerhout, Lucia G LeRoux, Brian P Hobbs et al. · 2012 · PLoS ONE

Background and purpose The purpose of our study was to utilize a molecular imaging technology based on the retrograde axonal transport mechanism (neurography), to determine if oxaliplatin-induced neurotoxicity affects retrograde axonal transport in an animal model. Materials and methods Mice (n = 8/group) were injected with a cumulative dose of 30 mg/kg oxaliplatin (sufficient to induce neurotoxicity) or dextrose control injections. Intramuscular injections of Tetanus Toxin C-fragment (TTc) labeled with Alexa 790 fluorescent dye were done (15 ug/20 uL) in the left calf muscles, and in vivo flu
