ABSTRACT Short-term memory is a form of cognitive function to store information in a short time, which is important to support daily work and learning activities. Circadian rhythm is a physical, mental, and behavioral changes that occurs in 24-hour daily cycle which is believed to be a factor that affecting short term memory , for example sleep-wake cycle. This study was aimed to determine the effect of routinity of aerobic on short-term memory in students at the Faculty of Medicine, University of Mulawarman. This analytic observational study with cross-sectional method used 94 male respondents at the Faculty of Medicine, Mulawarman University, consisting of the Medical Study Program, Dentistry Study Program, and Nursing with stratified random sampling technique. The research results showed the most circadian rhythm type is night chronotype as many as 71 people (76%) (p=0.031). Short-term memory scores were obtained by 41 people (44%) on good category and 53 people (56%) on bad category. It was concluded that there is an effect of circadian rhythm on short-term memory in Medical Study of The Medical Faculty of Mulawarman University.   Keyword : Circadian rhythm, Short-term memory, Medical student, Scenery Picture Memory Test (SPMT)   ABSTRAK Memori jangka pendek merupakan bentuk fungsi kognitif untuk menyimpan informasi yang tersedia dalam waktu yang singkat dimana hal ini penting untuk menunjang aktivitas pekerjaan maupun pembelajaran sehari-hari. Irama sirkadian adalah suatu perubahan fisik, mental, dan perilaku yang tejadi mengikuti siklus harian 24 jam yang diyakini sebagai faktor yang mempengaruhi memori jangka pendek, contohnya seperti siklus bangun tidur. Penelitian ini bertujuan untuk mengetahui pengaruh aerobik rutin terhadap memori jangka pendek pada mahasiswa di Fakultas Kedokteran Universitas Mulawarman. Penelitian observasional analitik dengan metode potong lintang ini menggunakan 94 responden laki-laki di Fakultas Kedokteran Universitas Mulawarman yang terdiri atas Program Studi Kedokteran, Program Studi Kedokteran Gigi, dan D3 Keperawatan dengan menggunakan teknik stratified random sampling. Hasil penelitian menunjukan tipe irama sirkadian terbanyak ialah kronotipe malam yaitu 71 orang (76%) dengan nilai p = 0,031. Nilai memori jangka pendek didapatkan 41 orang (44%) dalam kategori baik dan 53 orang (56%) kategori tidak baik. Disimpulkan bahwa terdapat pengaruh irama sirkadian terhadap memori jangka pendek pada Mahasiswa Fakultas Kedokteran Universitas Mulawarman.   Kata Kunci : Irama sirkadian, Memori jangka pendek, Mahasiswa kedokteran, Scenery Picture Memory Test (SPMT)

Coptosapelta flavescens Korth. is a liana plant from the Rubiaceae family. In East Kalimantan, it is also known as "Akar Tambolekar" or "Merung", it is called "akar" or

In this study, CuO–TiO2 nanofiber catalysts were fabricated by an electrospinning process, followed by thermal annealing at various temperatures ranging from 300 to 700 °C. The phase transformation from CuO to metallic Cu was carried out through immersion treatment in NaBH4 solution. The resulting CuO–TiO2 and Cu–CuO–TiO2 nanofibrous mats were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and Brunauer–Emmett–Teller (BET) analysis. The results revealed that the crystalline phase composition of the nanofibrous mats considerably affected the efficiency of photocatalytic reduction, where the CuO–TiO2 catalysts with a predominant anatase content was found to be more photoactive than the rutile phase. Similarly, the presence of both Cu and CuO species was more beneficial for promoting the activity of fibers by acting as an interim location for facilitating the electron transfer. The fabricated Cu–CuO–TiO2 nanofibrous mat with a ratio presented high conversion (∼99%) within several minutes with the apparent pseudo-first-order rate constant of 0.42 and 0.50 min–1 in the absence and presence of UV light irradiation as well as excellent stability in recycling runs with a stable conversion efficiency of 97% or higher over five successive catalytic cycles.

Keywords: Acorus calamus, spasmolytic, ileum isolated organ ABSTRAKRasa nyeri akibat kekakuan otot polos dapat terjadi pada berbagai keadaan pasien, mulai dari keadaan normal seperti nyeri haid, hingga keadaan patologis seperti infeksi saluran pencernaan. Untuk mengatasi rasa nyeri maka dapat diberikan obat spasmolitik untuk mengurangi kekakuan otot polos, namun terdapat efek samping dari obat tersebut. Dengan demikian maka perlu pengembangan obat baru spasmolitik berbasis tumbuhan obat dengan efek samping yang lebih sedikit. Penelitian ini dilakukan untuk menguji potensi ekstrak rimpang jeringau (Acorus calamus L.) yang secara tradisional digunakan etnis Dayak sebagai obat sakit perut. Aktivitas spasmolitik ekstrak tumbuhan diuji dengan metode isolat organ ileum marmut yang diinduksi dengan histamin. Aktivitas spasmolitik A. calamus 0,3 mg/ml mampu menurunkan tonus ileum marmut lebih baik dibanding papaverin 0,03 mg/ml (p=0,00). Kesimpulan penelitian ini adalah ekstrak rimpang jeringau (A. calamus) berpotensi digunakan sebagai spasmolitik dalam penatalaksanaan masalah kesehatan akibat kontraksi otot polos.

e108 14th International Congress on Infectious Diseases (ICID) AbstractsResults: AMI was found in 2.47%(9/365), 1.29%(6/465), 0.96%(4/418), 1.06%(3/283) of malaria patients in the year 1995, 1996, 1997, 1998 respectively and 0.87%(96/11005), 0.87%(97/11113), 0.87%(75/8646), 0.71%(47/6624) of nonmalarial in-patients during the corresponding period. The occurrence of AMI gradually decreased in malaria patients as the years progressed -from 2.47% in 1995, when Mangalore experienced a resurgence of malaria, to 1.06% in 1998.Conclusion: Compilation of 4-year data has shown a higher occurrence of AMI among all malaria patients (1.44%) compared to AMI among all in-patients other than due to malaria (0.82%), (p<0.05). These findings suggest that AMI should be regarded as an important clinical complication of malaria. This is of importance since some of the anti malarial drugs also depress cardiovascular function.
