Research ArticleOpen accessIn the abstractEarly Responses of Neural Cells (U87) to Particulate Matter Exposure: Cell Viability and Cytokine ConcentrationJae-Sik Jeon, Eun Ju Oh, Qian-Wen Wang, Jae Kyung KimParticulate Matter (PM) has a significant impact on human health and increases the risk of respiratory diseases. PM exposure is linked to various illnesses, including cardiovascular diseases, cancer, neurological diseases, and pregnancy complications, and contributes to both mortality and morbidity globally. PM can also influence the autonomic nervous system. The evidence suggests that the likelihood of developing lung cancer continually … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 1 · 20 Feb 2023 · 5,450 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimized Earthquake Evacuation Routes Using Dijkstra's Algorithm and WinQSBSandra Huarcaya Gonzales, Hugo Vega-Huerta, Gisella Luisa Elena Maquen-Niño et al.This research analyzes and generates optimal evacuation routes in the Barranco district during earthquake scenarios using the Dijkstra algorithm implemented through WinQSB. A preliminary review was conducted to establish key concepts related to earthquake dynamics, evacuation route planning, and the application of Dijkstra’s algorithm. Given its high seismic exposure and the prevalence of aging infrastructure, Barranco is considered highly vulnerable … …Journal of Computer Science, Vol. 21, Issue 10 · 9 Dec 2025 · 2,851 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffective Strains of Beauveria Bassiana and B. Pseudobassiana used Against the Asian Locust (Locusta Migratoria L.) in KazakhstanUlzhalgas T. Zhumataуeva, Bakhytzhan A. Duissembekov, Yerlan Dutbayev et al.The purpose of the study was to perform genetic identification of the strains of fungi of the Beauveria genus and evaluate the effect of abiotic factors on the growth and survival of colonies and the productivity of conidia of these fungi, as well as to determine the biological effectiveness of the semi-preparative form of the drug based on Beauveria bassiana … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 22 Nov 2022 · 5,702 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Seasonal Temperature on the Genotypic Variability of Flowering Duration in Pearl Millet (Pennisetum glaucum) in NigerSani Daouda Ousmane, Mouhamadou Mounkaila Boureima, Maman Nassourou Lawali et al.Heat stress is a major contributor to crop losses worldwide. Millet [Pennisetum glaucum (L.) R. Br.] is a staple crop for inhabitants of arid and semi-arid regions of the world, due to its extraordinary adaptation to drought and high temperatures. Climate change points to an overall increase in temperature, the effect of which on crop growth and productivity remains to … …American Journal of Agricultural and Biological Sciences, Vol. 17, Issue 1 · 30 Nov 2022 · 6,125 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIn-vitro Larvicidal Potentials of Achillea Extracts on Strongylid LarvaeLyudmila Lider, Yerlan Suleimen, Gulnur Mamytbekova et al.Strongylid infections remain among the most widespread and clinically significant helminthoses in horses, with increasing concerns regarding anthelmintic resistance. Against this background, we investigated the in-vitro larvicidal activity of Achillea salicifolia and Achillea setacea extracts against strongylid larvae. We evaluated concentrations of 20, 30, and 40% at exposure times of 0.5, 1, 2, and 4 h (n = 3). Larval … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 2 · 21 Jul 2026 · 1,032 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalysis of Indoor CO2 Concentration Using Split Ventilation Systems as an Indicator of COVID-19 TransmissionManuel Batista, Oscar Bulgim, Ericka Matus et al.We measured the indoor CO2 concentration in occupied areas with ventilation systems that recirculate air without an external air supply. The average time required to achieve the highest probability of contagion was also measured based on the number of participants in the group. Three different experimental groups were evaluated: Group One (G1), which included 5 participants; Group Two (G2), with … …American Journal of Applied Sciences, Vol. 20, Issue 1 · 23 Aug 2023 · 6,051 accessesView PDF Cite

Research ArticleOpen accessIn the abstractReversible Ionizing Radiation Sensors Based on Carbon NanotubesKenneth Fontánez, Abniel Machín, María C. Cotto et al.Vertically Aligned Carbon Nanotubes (VA-CNTs) were grown by Chemical Vapor Deposition (CVD) on a silicon substrate with alternating layers of TiN and SiO2. VA-CNTs were exposed to X-ray radiation to study the change in resistivity later. Preliminary results show an increase in the resistivity of CNTs as a function of radiation exposure time, which means that the structure responds successfully … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 3 Feb 2020 · 7,230 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiodegradation of Low-Density Polyethylene Film by UV Irradiated and Non-Irradiated Pseudomonas Aeruginosa D5Olusola Adeoye Oluwole, Temitayo Omotunde Olowomofe, Ikeoluwa Gloria OlaniyanLow-density polyethylene (LDPE) constitutes 60% of total plastic production, and non-degradable polyethylene carry bags are the most common type of solid waste found. Their recalcitrance in the environment is thus a major concern for environmentalists. This study investigated the potential of Ultraviolet (UV) induced mutation in enhancing biodegradation of LDPE films by two diesel degrading bacteria, Alcaligenes faecalis D4 and … …Current Research in Microbiology, Vol. 8, Issue 1 · 8 Oct 2025 · 3,629 accessesView PDF Cite

Case ReportOpen accessIn the abstractBrief Report: 20-Year Follow-Up of an Infant with Neurological Impairment Born to a Mother with Variant Creutzfeldt-Jakob DiseaseJustin Penner, Anjali Rampersad, James E. Burns et al.A term infant born via uncomplicated caesarian section was noted to be jittery, hypotonic, and have pooling of secretions at birth. Over the first four weeks of life, the infant developed four limb hypertonia, hyperreflexia, and clonus. MRI at 3.5 weeks old showed brain immaturity, poor myelination, and increased signal in the dorsal thalami. At six months, dystonic features with … …American Journal of Infectious Diseases, Vol. 21, Issue 1 · 7 Mar 2025 · 7,660 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnthelmintic Treatment in Growing Cattle: A Preliminary Study on the Effect of Ricobendazole on the Fecal MicrobiomePablo Rovira, Pablo LorenzoThere is limited information on the impact that anthelmintic treatments exert on the fecal microbiome of growing cattle. This study characterizes the composition and metabolic function of the cattle gut microbiome associated with different levels of parasite Fecal Egg Counts (FEC) and characterizes the fecal microbiome before and after ricobendazole-treatment.
