Multicellular Organisms

Early multicellular organisms must gain adaptations to outcompete their unicellular ancestors, as well as other multicellular lineages. The tempo and mode of multicellular adaptation is influenced by many factors including the traits of individual cells. We consider how a fundamental aspect of cells, whether they reproduce via binary fission or budding, can affect the rate of adaptation in primitive multicellularity. We use mathematical models to study the spread of beneficial, growth rate mutations in unicellular populations and populations of multicellular filaments reproducing via binary fission or budding. Comparing populations once they reach carrying capacity, we find that the spread of mutations in multicellular budding populations is qualitatively distinct from the other populations and in general slower. Since budding and binary fission distribute age-accumulated damage differently, we consider the effects of cellular senescence. When growth rate decreases with cell age, we find that beneficial mutations can spread significantly faster in a multicellular budding population than its corresponding unicellular population or a population reproducing via binary fission. Our results demonstrate that basic aspects of the cell cycle can give rise to different rates of adaptation in multicellular organisms.

Number Of Particles

Nucleic acid-containing particles in the cytoplasm of Amoeba proteus (cf. reference 1) were counted after acridine orange staining. The number of particles per ameba was found to be correlated with cell age and size. Fresh daughters had a mean particle number of 5400, whereas predivision amebae contained around 11,000 particles. Amebae from two other strains contained similar particles. The particles were found to be clustered in fasted cells and redispersed after feeding. A marked increase in the particle population was noted in anucleate fragments. These results, together with those previously presented, suggest that the particles multiply intracellularly. Their nature and their relationship to previous work on nucleic acid labeling in Amoeba are discussed.

Public Health Development

Health services are one type of public service that is the spearhead of public health development. People who care about health have started to establish health communities such as healthy homes or nutrition houses such as the Herbalife healthy home. Herbalife's healthy home uses a special scale, the tanita scale, as an indicator of consumer fitness and health. With technological developments, an application is needed that can help carry out consumer health checks. The methodology used in making this application is the prototype model. The programming language used is Kotlin. Meanwhile, the tools and editors used are Android Studio. The method used in data collection in this study is the method of literature, observation, and interviews. With this built application, it can help in determining the health of consumers from several parameters used in this study, including body fat, belly fat, cell age, and health. The output of these parameters is then used as input for the application being built.   Layanan kesehatan menjadi salah satu jenis layanan publik yang merupakan ujung tombak dalam pembangunan kesehatan masyarakat. Komunitas masyarakat yang peduli kesehatan mulai mendirikan komunitas kesehatan seperti rumah sehat atau pun rumah nutrisi seperti rumah sehat Herbalife. Rumah sehat Herbalife menggunakan timbangan khusus yakni timbangan tanita sebagai alat indikator kebugaran dan kesehatan konsumen. Dengan perkembangan teknologi, maka dibutuhkan aplikasi yang bisa membantu melakukan pemeriksaan kesehatan konsumen. Metodologi yang digunakan dalam pembuatan aplikasi ini yakni model prototype. Bahasa pemrograman yang digunakan yaitu Kotlin. Sedangkan tools dan editor yang digunakan yakni Android Studio. Metode yang digunakan dalam pengumpulan data dalam penelitian ini yakni metode kepustakaan, observasi, dan wawancara. Dengan adanya pengembangan aplikasi ini, maka dapat membantu dalam menentukan kesehatan konsumen dari beberapa parameter yang digunakan antara lain yakni lemak tubuh, lemak perut, usia sel, dan kadar air. Output dari beberapa parameter tersebut kemudian dijadikan sebagai input untuk aplikasi yang dibangun.
