Antimicrobial resistance has become a critical global public health challenge, with irrational antibiotic use being one of its primary drivers. In Morocco, data on antibiotic use among older adults remain scarce, particularly regarding … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 13 Apr 2026 · 1,370 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimating the Genetic Polymorphisms of Gujarat Population using 17 Y Chromosomal STR lociAditi Mishra, Ulhas Gondhali, Sumit ChoudharyThe present study aims to report genetic variations in unrelated male (n = 118) of the Gujarat population with the help of seventeen Y-STR markers (DYS456, DYS389I, DYS390, DYS389II, DYS458, DYS19, DYS385a/b, DYS393, DYS391, DYS439, DYS635, DYS392, Y GATA H4, DYS437, DYS438 and DYS448). Allele frequencies and forensic parameters were calculated. A total of 96 distinct alleles were reported with … …OnLine Journal of Biological Sciences, Vol. 21, Issue 2 · 23 Jun 2021 · 6,506 accessesView PDFCite
EditorialOpen accessIn the abstractAssociation between Infective Endocarditis and Premalignant Colorectal LesionsCarles FalcesThe association between Infective Endocarditis (IE) and Colorectal Cancer (CRC) has been known for more than 50 years. The microorganisms in which this association has been described are Streptococcus gallolyticus (formerly Streptococcus bovis) (Corredoira-Sánchez et al., 2012; Boleij et al., 2011), in different subspecies and, more recently, Enterococcus faecalis (Pericàs et al., 2016; 2017; Escolà-Vergé et al., 2020; Pericàs et … …American Journal of Infectious Diseases, Vol. 17, Issue 3 · 10 Jun 2021 · 11,566 accessesView PDFCite
Research ArticleOpen accessIn the abstractEcophysiology of Chirostoma Jordani Pisces: Atherinopsidae. Habitat Characterization and Population Dynamics in a Periurban Lake (Xochimilco, México)Latournerié-Cervera José Román, Rangel-Nambo María Isabel, Alma Rosa Estrada-OrtegaChirostoma Jordani is an endemic species of the Mexican plateau, whose population, due to anthropogenic causes, has experienced a notable decrease from 2000 to the present, putting its permanence in its natural habitat at risk. Therefore, the objectives of this research were focused on evaluating the population dynamics of C. Jordani through its size and weight distributions and growth rate … …American Journal of Agricultural and Biological Sciences, Vol. 16, Issue 1 · 23 Jan 2021 · 7,548 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy on the Synergistic Treatment of Soil Fumigation and Biocontrol Bacteria for the Prevention and Control of Root-Knot Nematodes in Facility SoilLijin Qin, Yingmin Hu et al.Years of continuous cropping have led to the inability to cure root-knot nematode disease. In this study, soil fumigation was used before tomato planting to study the decline rate and the effect of root-knot nematode population control after soil fumigation. During the experiment, "Wofengkang" organic sulfur soil fumigant was used. A constant temperature drying oven was used to artificially simulate … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 26 Sep 2024 · 4,843 accessesView PDFCite
Research ArticleOpen accessIn the abstractTestosterone Concentration, Libido and Spermatozoa Quality in Gembrong Goats after in vivo and in vitro PGF2α AdministrationHusnurrizal, Sri Wahyuni et al.The Gembrong goat population is currently in a critical state. The preliminary study results show that one of the factors causing the population decline is the low fertility of male goats characterized by low sperm quality. The improvement of the spermatozoa quality can be performed with the administration of PGF2α. This study aims to determine the difference in semen quality … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 2 · 29 Apr 2024 · 5,549 accessesView PDFCite
Research ArticleOpen accessIn the abstractProbe-based Semi-permanent Soil Humidity SensorSoobin Jeon, Dongmahn SeoThe modern agricultural environment has the problems of an aging rural population and a decreasing rural labor population. Recently, smart farms based on information and communication technology have been studied to address environmental issues in agriculture. The smart farm consists of three parts: a data collection unit, a processing unit, and a control unit. Among them, the data collection unit … …Journal of Computer Science, Vol. 21, Issue 10 · 16 Dec 2025 · 1,929 accessesView PDFCite

Most of these studies were local in nature, while our work is characterized by a generalizing and comparative … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 4 Dec 2024 · 4,556 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdipose-Derived Canine Mesenchymal Stem Cells in PLAY® MediaArjun Kulkarni, Bhavana N. V., Teena Mary Thomas et al.In veterinary medicine, stem cell-based therapies present promise for addressing orthopedic and degenerative conditions in canines. Mesenchymal Stem Cells (MSCs) possess unique regenerative, immunomodulatory, and differentiation capabilities. However, their efficacy relies on optimal in-vitro conditions. Prolonged expansion over passages leads to a gradual loss of stem cell traits, highlighting the importance of optimized culture conditions and media supplements.
