(1) Background: This study aimed to investigate the effects of proprioceptive neuromuscular facilitation pattern kinesio taping on arm swing, balance, and gait parameters among chronic stroke patients. (2) Methods: Twenty-eight participants were randomized into proprioceptive neuromuscular facilitation pattern kinesio taping during gait training ( = 14) and gait training ( = 14) groups. The proprioceptive neuromuscular facilitation pattern kinesio taping during gait training group employed proprioceptive neuromuscular facilitation pattern kinesio taping during 15 min treadmill-based gait training five times a week for four weeks, while the gait training group underwent the same gait training without proprioceptive neuromuscular facilitation pattern kinesio taping.

Colorectal cancer (CRC), one of the most common cancers worldwide, continues to increase in incidence and mortality rates. This trend is closely linked to changes in dietary habits, which are major risk factors for colorectal cancer. The increase in the incidence of CRC in countries previously considered low-risk and with low socioeconomic status is most likely due to lifestyle and dietary changes.

Polyurethane (PU), currently replacing existing synthetic materials worldwide, is a synthetic polymer derived from polyols, isocyanates, and a chain extender added by condensation reactions. PU wastes which are difficult to recycle, are commonly discarded in landfills and flow into ecosystems, thereby causing serious environmental problems. In recent years, insect-associated microbes have become a promising, eco-friendly strategy as an alternative to plastic recycling.

Article Synopsis
  • Electroporation is primarily used for transforming Bacillus thuringiensis (Bt) but is not universally applicable to other strains.
  • Polyethylenimine (PEI) serves as a non-viral vector forming polymeric nanoparticles (PNPs) that are efficient, easy to make, and low in toxicity.
  • The study confirmed that PEI-based PNPs can successfully transform Bt strains with efficiency similar to electroporation, indicating a promising alternative method.

Background: Bacillus thuringiensis (Bt) has been widely used as a biological control agent for lepidopteran pests. However, resistance to Bt is a major concern associated with Spodoptera spp. (Noctuidae) and Plutella xylostella (Plutellidae).

Computation offloading enables intensive computational tasks in edge computing to be separated into multiple computing resources of the server to overcome hardware limitations. Deep learning derives the inference approach based on the learning approach with a volume of data using a sufficient computing resource. However, deploying the domain-specific inference approaches to edge computing provides intelligent services close to the edge of the networks.

RNA interference (RNAi) has attracted attention as a promising approach to control plant viruses in their insect vectors. In the present study, to suppress replication of the rice stripe virus (RSV) in its vector, , using RNAi, dsRNAs against genes that are strongly upregulated upon RSV infection were delivered through a rice leaf-mediated method. RNAi-based silencing of peroxiredoxin, cathepsin B, and cytochrome P450 resulted in significant down regulation of the NS3 gene of RSV, achieving a transcriptional reduction greater than 73.

Electric-vehicle technology is an emerging area offering several benefits such as economy due to low running costs. Electric vehicles can also help to significantly reduce CO 2 emission, which is a vital factor for environmental pollution. Modern vehicles are equipped with driver-assistance systems that facilitate drivers by offloading some of the tasks a driver does while driving.

Article Synopsis
  • Insect growth regulators (IGRs) are being explored as safer alternatives to traditional insecticides, with actinomycetes potentially offering new compounds for this purpose.
  • The study screened 363 actinomycetes and identified Streptomyces sp. AN120537 as the most effective, which produced juvenile hormone antagonists (JHANs) and showed strong insecticidal effects.
  • Five active compounds known as antimycins were isolated, demonstrating significant insecticidal activities and causing deformities in treated larvae, indicating their potential application as broad-spectrum IGR insecticides.

Insect growth regulators (IGRs) are attractive pest control agents due to their high target specificity and relative safety to the environment. Recently, plants have been shown to synthesize IGRs that affect the insect juvenile hormone (JH) as a part of their defense mechanisms. Using a yeast two-hybrid system transformed with the Aedes aegypti JH receptor as a reporter system, we identified several JH agonists (JHAs) and antagonists (JHANs) causing retardation in the ovarian development of female Asian tiger mosquito, Aedes albopictus, from plant essential oil compounds.

Background: Automobile assembly workers repeatedly place burdens on their lumbar regions, which can lead to mechanical chronic low back pain.

Objective: This study aimed to compare the effects of lumbar stabilization exercises performed on a stable or unstable surface on lumbar pain, muscle strength, stability, disability, and depression in patients with chronic low back pain.

Methods: Twenty-four patients were randomly allocated to a stable or unstable surface group (n = 12 each).
