PENGARUH METODE PEMBELAJARAN BUZZ GROUP BERBANTU MEDIA AUDIO VISUAL TERHADAP KEAKTIFAN BELAJAR SISWA PADA MATERI PENJUMLAHAN DAN PENGURANGAN KELAS 1 SDN KALIALANG

Tujuan dari penelitian ini untuk mengetahui pengaruh metode pembelajaran Buzz Group berbantu media audio visual terhadap keaktifan belajar siswa pada materi penjumlahan dan pengurangan kelas 1 SDN Kalialang. Jenis penelitian ini menggunakan metode penelitian kuantitatif, dengan model Pre Experimental Design bentuk one group pretest-posttest design. Populasi dalam penelitian ini adalah seluruh siswa kelas 1 SDN Kalilang tahun ajaran 2021/2022. Sampel yang diambil adalah 12 siswa kelas 1 yang menggunakan teknik sampling jenuh.  Data dalam penelitian ini diperoleh melalui melalui wawancara, angket, test dan dokumentasi. Data dalam penelitian ini diambil dengan teknik pengisian angket. Berdasarkan hasil analisis data, diketahui bahwa rata-rata skor keaktifan akhir lebih tinggi dibandingkan dengan skor keaktifan awal (87,75>37,5). Hasil analisis uji-t diperoleh hasil thitung sebesar 21,2894 dan ttabel sebesar 2,242 dan taraf signifikan 0,05, karena thitung > ttabel yaitu 21,2894>2,242 sehingga Ha diterima dan H0 ditolak. Artinya ada pengaruh metode Buzz Group berbantu media audio visual terhadap keaktifan belajar siswa pada materi penjumlahan dan pengurangan kelas 1 SDN Kalialang

How consistent are the transcriptome changes associated with cold acclimation in two species of the Drosophila virilis group?

This work was financially support by a Marie Curie Initial Training Network grant, “Understanding the evolutionary origin of biological diversity” (ITN-2008–213780 SPECIATION), grants from the Academy of Finland to A.H. (project 132619) and M.K. (projects 268214 and 272927), a grant from NERC, UK to M.G.R. (grant NE/J020818/1), and NERC, UK PhD studentship to D.J.P. (NE/I528634/1).For many organisms the ability to cold acclimate with the onset of seasonal cold has major implications for their fitness. In insects, where this ability is widespread, the physiological changes associated with increased cold tolerance have been well studied. Despite this, little work has been done to trace changes in gene expression during cold acclimation that lead to an increase in cold tolerance. We used an RNA-Seq approach to investigate this in two species of the Drosophila virilis group. We found that the majority of genes that are differentially expressed during cold acclimation differ between the two species. Despite this, the biological processes associated with the differentially expressed genes were broadly similar in the two species. These included: metabolism, cell membrane composition, and circadian rhythms, which are largely consistent with previous work on cold acclimation/cold tolerance. In addition, we also found evidence of the involvement of the rhodopsin pathway in cold acclimation, a pathway that has been recently linked to thermotaxis. Interestingly, we found no evidence of differential expression of stress genes implying that long-term cold acclimation and short-term stress response may have a different physiological basis.PostprintPeer reviewe

An Overview of the History, Ecology, and Phylogeny of Powassan Virus in Maine

Importance: Powassan virus is a tick-transmitted flavivirus that is increasingly reported and can cause fatal human encephalitis. Two lineages circulate in nature: lineage I (Powassan virus-1) is transmitted primarily by the woodchuck tick Ixodes cookei and the squirrel tick I. marxi, and lineage II (deer tick virus) is transmitted by the deer tick I. scapularis. Both lineages can cause human disease and are serologically indistinguishable. In Maine, human cases are increasing—35 cases were reported from 2000 to 2024, of which 14 were reported between 2022 and 2024. Objective: This review summarizes our current understanding of the history, ecology, and phylogeny of Powassan virus in Maine, as well as human demographics of Powassan virus disease. Review: Because Powassan virus encephalitis is a rare and emerging disease in the United States, there is limited published literature available. Keywords used in the literature search included “Powassan virus,” “tick-borne encephalitis virus,” “deer tick virus,” “Ixodes scapularis,” and “Maine.” Findings: Human cases of Powassan virus encephalitis are rising, and Powassan virus is now the most common cause of arboviral encephalitis in Maine. Seasonality of cases coincide with all stages of ticks, but fall and spring cases overlap with peak activity of the adult deer tick. Phylogenetic studies have shown that deer tick virus likely emerged in the northeastern United States between 1940 and 1975, and then expanded northward with the reestablishment of the white-tailed deer and I. scapularis ticks. Conclusions: Additional research is warranted to better characterize the transmission dynamics of Powassan virus in nature and further our understanding of human disease

Potential of vascular endothelial growth factor as a biomarker of coronary artery disease in subjects undergoing CABG surgery

Introduction: • Coronary artery disease (CAD) causes local hypoxia due to reduced blood flow • Hypoxic conditions are known to induce vascular endothelial growth factor (VEGF) production, a key contributor to angiogenesis • The purpose of this study was to determine the potential of VEGF as a marker of myocardial stress in subjects with CAD undergoing coronary artery bypass grafting (CABG) surger
