Research ArticleOpen accessIn the abstractFirst Morphoanatomical and Cytogenetic Characterization of Picria fel-terrae Lour.: A Local Accession from Dairi Regency, IndonesiaElimasni, Deny Supriharti, HaryatiPoguntano (Picria fel-terrae Lour.) plant has been widely recognized for its medicinal properties due to its bioactive compounds. However, fundamental biological studies, particularly on its phenological and cytogenetic characteristics, remain limited. This study aimed to characterize the vegetative morphology and karyotypic features of P. fel-terrae from Dairi Regency, North Sumatra, to provide a comprehensive cytogenetic database for future study and … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 17 Jul 2026 · 745 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimizing Boar Epididymal Sperm Preservation: Comparative Analysis of Slicing Float-Up vs. Flushing and BTS vs. Andromed® Extenders on Sperm Motility and Morphometry TraitsMamonene Angelinah Thema, Ntuthuko Raphael Mkhize, Gerhard van der Horst et al.Epididymal sperm collection represents a valuable strategy for preserving genetics from deceased or castrated boars of superior breeding value. The two primary collection methods-slicing float-up (high sperm yield) and flushing (low blood contamination risk)-differ in sperm recovery efficiency, while semen extenders provide cryoprotective nutrients that protect against cold shock during preservation. This study compared the effects of slicing float-up versus … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 14 Mar 2026 · 1,794 accessesView PDFCite
Research ArticleOpen accessIn the abstractEpigenetic Regulation of Extracellular Matrix Remodeling in Skin Aging: Mechanisms and InteractionsJiguang Yang, Yusong Shi, Xiaoqing YanSkin aging results from complex interactions between genetic factors, environmental stressors, and epigenetic modifications that regulate extracellular matrix (ECM) remodeling. Accumulation of senescent cells impairs tissue regeneration through mechanisms including telomere shortening, reactive oxygen species accumulation, and ultraviolet (UV) radiation exposure. While epigenetic pathways regulate skin homeostasis, regeneration, and senescence, the specific epigenetic changes occurring during UV exposure, chronological aging, … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 15 Feb 2026 · 1,458 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenotype Screening of Bovine Brachyspina in Taiwan Holstein CowsChun Hsuan Chao, Yi Ming Chen, Kuo Hua LeeThis study analyzed carrier frequencies of the genetic defect bovine brachyspina (BS) in the Holstein cows in Taiwan. In total, 1688 cows from 31 herds were included in the analysis, performed using the Igenity-Prime 50K single-nucleotide polymorphism chip. Of the 1688 cows, 68 (5.09%) were BS carriers (BY), a frequency lower than that reported in Taiwan previously. In Taiwan, the … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 3 · 14 Aug 2020 · 6,971 accessesView PDFCite
Research ArticleOpen accessIn the abstractSSR Analysis of the Chloroplast and Mitochondrial Genomes of Cultivar Lines and Wild Types of the Sunflower (Helianthus L.)Vladimir Arturovich Khachumov, Alexander Vyacheslavovich Usatov, Kirill Vitalievich Azarin et al.SSR analysis of chloroplast and mitochondrial genomes of cultivar lines and wild species of sunflower (Helianthus L.) were completed. The polymorphism of 18 microsatellite loci of the chloroplast and mitochondrial genomes was investigated. Based on the obtained data was constructed dendrogram showing the genetic diversity of chloroplast and mitochondrial genomes of sunflowers. The studied species were clustered into annual and … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 19 Feb 2020 · 7,675 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimizing Pea Cultivation in Kazakhstan: Breeding Drought-Resistant Varieties for Sustainable AgricultureKudaibergenov Mukhtar Sarsenbekovich, Kanatkyzy Makpal, Saken Gaukhar Sakenkyzy et al.Peas (Pisum sativum L.) are a vital legume for global food security, yet its cultivation in Kazakhstan faces challenges due to arid conditions and limited moisture availability. Breeding high-yielding, stress resistant varieties is critical to enhance agricultural productivity in the region. This study aimed to develop pea varieties with improved yield, drought resistance, and mechanization adaptability under Kazakhstan's agroecological conditions. … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 25 Aug 2025 · 5,249 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Molecular Markers ISSR, SSR and RFLP to Study the Genetic Variation of Strawberry CultivarsGanies Riza Aristya, Rina Kasiamdari, Muhammad Fauzi Arif et al.Strawberry is grown in Indonesia because it has potential high economic value. The purpose of this study was to investigate relationship of phenetic lineage and genetic variations in 12 strawberry cultivars using three different molecular marker methods, including ISSR, SSR and RFLP. Five primers of ISSR markers were used and they generated 53 bands with 44 polymorphic DNA bands.

Research ArticleOpen accessIn the abstractGenetic Diversity of Three Indigenous Cattle Breeds Reared in BeninMahugnon Santoze Adido, Mathew Gitau Gicheha, Mahougnon Camus Adoligbe, Kodzo AtchouLivestock production is an important component of the Benin economy contributing an upward of 25% of the agricultural Gross Domestic Products (GDP). Indigenoues cattle sector contributes more to the GDP compared to other livestock species. Despite the economic role played by the sector, there has been little or no efforts to genetically improve the indigenous cattle in the country.

Research ArticleOpen accessIn the abstractSubset ARMA Model Identification for Monthly Electricity Consumption DataAmaal El Sayed Abd El Ghany MubarakSubset models can always be highly influential in series analysis, particularly when the data demonstrate a sort of form in periodic behavior with miscellaneous natural period's ranges, specifically; days, weeks, months and years. Subset models can also be effective as they let the number of parameters lower allowing only the really needed ones to be present in the model.
