Wabah COVID-19 telah menjadi pandemi global yang memengaruhi banyak negara, termasuk Indonesia. Pemerintah dan lembaga kesehatan telah melaksanakan berbagai langkah untuk mencegah penyebaran COVID-19. Salah satu langkah penting adalah menggalakkan kebiasaan hidup bersih dan sehat sebagai upaya pencegahan penyebaran COVID-19 di kelurahan Tamanan, Kota Kediri. Pengabdian masyarakat ini bertujuan untuk meningkatkan pemahaman masyarakat tentang kebiasaan hidup bersih dan sehat sebagai upaya pencegahan penyebaran COVID-19. Metode yang digunakan dalam pengabdian masyarakat ini adalah pendekatan partisipatif dengan melibatkan masyarakat secara aktif dalam pengumpulan data dan pelaksanaan kegiatan. Kegiatan yang dilakukan meliputi penyuluhan, demonstrasi, dan penyediaan fasilitas sanitasi. Aktivitas ini diikuti oleh 50 ibu rumah tangga selama 3 bulan, terdiri dari tiga kegiatan utama penyuluhan kesehatan tentang pola hidup bersih dan sehat untuk mencegah penularan COVID-19. Data untuk penilaian kebiasaan hidup sehat menggunakan instrumen kuesioner dan checklist sebelum dan sesudah pelatihan. Pengetahuan, sikap dan psikomotor ibu rumah tangga dalam penyebaran penularan COVID-19 setelah diberikan pelatihan kebiasaan hidup sehat selama 3 bulan mengalami peningkatan. Penilaian dilakukan dengan membandingkan hasil pre-test dan post-test pelatihan peserta. Setelah mengikuti pelatihan, sebagian besar kemampuan peserta masuk kategori tinggi pada aspek pengetahuan (76%), aspek sikap (82%) dan aspek aspek psikomotor (92%). Berdasarkan hasil pengabdian ini, dapat disimpulkan bahwa penggalakan kebiasaan hidup bersih dan sehat dapat menjadi upaya efektif dalam pencegahan penyebaran COVID-19 di kelurahan Tamanan, Kota Kediri.
Severe acute respiratory syndrome coronavirus (SARS-CoV) is an etiologic agent of respiratory disease that has a mortality rate of 10%. IL-1 actively participates in the inflammatory response to infection. SARS-CoV-2 appears to act on the activation and maturation of IL-1?, which in turn activates other proinflammatory cytokines, such as IL-6 and TNF-. Therefore, IL-1? is part of the cytokine storm generated by coronavirus infection. Elevated levels of the IL-1 receptor antagonist (IL-1Ra) in severe cases of COVID-19, and this marker have been associated with increased viral load, loss of lung function, lung damage, and risk of death. In addition, there is an increase in IL-1? levels in patients with severe COVID-19, and this is strongly associated with lung injury. IL-1 levels are associated with the virulence of the process, and significantly higher serum levels have been observed in severe symptomatic SARS-CoV-2 cases than in mild cases or in those infected with the 2003 SARS-CoV coronavirus or 2012 MERS coronavirus.
Crossing over is the occurrence of disconnection and reconnection followed by a reciprocal exchange between the two chromatids in a bivalent form. The crossing event will produce parental type and recombinant type. In the event of crossing over, various factors can influence it. These factors can be due to internal and external. Recently, various factors have been reported that influence the incidence of crossing over. These factors include age, temperature, radiation, and changes in chromosome structure. This research is a type of experimental research that uses a randomized block design. Randomized block design by crossing D. melanogaster strains ?N>< ?bcl and ?N>< ?ym and their reciprocals. From the results of this cross (F1) then cross again ?N with the recessive male (from stock) then observe the phenotype of the offspring (F2) and calculate the results of the offspring. The F2 ?N crosses were treated with age variations, namely 0, 3, 6, 9, 12, 15, and 18 days. Based on the results of these crosses, the derived strains that appeared in the F2 crosses showed the phenomenon of crossing over with the influence of the age of the female and the type of strain on crossing events. the frequency or value of crossing over (formation of recombinants) decreased with the increasing age of the female. If the age of the female affects the frequency of crossing over, then the older the female, the more likely the frequency of crossing over will decrease. However, because the data obtained were incomplete, it was not possible to know the effect of female age on the frequency of crossing over of D. melanogaster crosses ?N>< ? bcl and ?N >< ?ym and their reciprocals. The condition for crossing over is the formation of a synaptonemal complex. Age of D. melanogaster females has an effect on the frequency of crossing over in crosses N? >< bcl?, N? >< ym?, and their reciprocals. The older Drosophila melanogaster is, the lower the frequency of crossing over will occur. Based on this, it was necessary to cross D. melanogaster with strains N, bcl, and ym. A cross consists of ?N ><?bcl and ?N ><?ym and their reciprocals. By crossing ?N with a recessive male from the stock, then observing the F2 phenotype, it is hoped that crossing over will occur. So that you can better understand by doing the practice directly. In this case, the effect of crossing over is seen from the age of the female and the type of strain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
