Abstract

Asthma is a disease defined as chronic inflammation of the airways which is characterized by recurrent coughing and shortness of breath. Dermatoglyphs are the appearance of tendrils and tendril patterns on the fingers, palms, toes and soles. Dermatoglyph is used as an aid in the detection of a number of diseases that have a strong heritable basis and is also used to detect abnormalities. This study aims to analyze and compare the patterns of dermatoglyphics in asthma sufferers and non-asthmatics on the fingertips. This type of research is descriptive research with cross sectional sampling method. Samples were taken from the student population of the Faculty of Mathematics and Natural Sciences, Padang State University as many as 100 samples of fingerprint patterns. The results obtained showed that there was a significant difference in the number of arch fingerprint patterns of asthmatics compared to normal individuals. Seeing this significant difference in numbers indicates a possible link between fingerprint patterns and asthma phenotypes.

Abstract

Polyploidy induction has emerged as a promising approach to improve plant traits through genetic and physiological modification. Oryzalin, a dinitroaniline herbicide, has been widelu recognized as an effective and less toxic alternative to colchicine for chromosome doubling in plants. This review aims to evaluate the effects of oryzalin-induced tetraploidy on the morphological, anatomical, and physiological characteristics of several plant species, including Colocasia esculenta, Citrullus lanatus, Tectona grandis, and Humulus lupulus. This study employed a narrative review with a systematic literatur search approach by collecting and analyzing previous studies related to the morphological and cytological responses of oryzalin treatments. The results indicate that oryzalin effectively induced tetraploidy, characterized by enlarged stomata size, reduced stomatal density, and altered leaf morphology, although species-specific responses were observed. The optimal oryzalin concentrations varied among species: 30 μM for C. esculenta, 72.2 μM for C. lanatus, 7.5 μM for T. grandis, and 10 μM for H. lupulus. In conclusion, oryzalin demonstrates strong potential as a safe and efficient mutagen for polyploid induction, supporting its application in plant breeding and genetic improvement. Further studies are required to optimize exposure duration and assess long-term physiological stability of induced polyploids.
