Determinan Perilaku Seksual Berisiko pada Remaja Makassar (Studi Kasus Santri Darul Arqam Gombara dan SMAN 6)

Abstract: Masa remaja adalah periode rasa ingin tahu yang besar dan ingin mencoba untuk meniru yang dilihat atau didengar. Rasa ingin tahu membuat remaja lebih permisif untuk melakukan perilaku seksual berisiko, namun diduga bahwa pemahaman gama akan menjadi faktor pembeda. Penelitian ini bertujuan mengetahui pengaruh pemahaman agama, peran orangtua, peran teman sebaya dan penggunaan media sosial terhadap perilaku seksual berisiko pada remaja dengan membandingkan antara santri Madrasah Aliyah di Pesantren Darul Arqam Gombara dengan siswa SMAN 6 Makassar. Penelitian observasional dengan rancangan cross sectional study, melibatkan 79 santri MA Darul Arqam Gombara yang dipilih secara keseluruhan dan 274 orang siswa SMAN 6 yang dipilih secara proporsional stratified random sampling. Analisis menggunakan analisis univariat dan bivariat dengan uji chi square dan uji phi. Hasil penelitian ditemukan ada pengaruh peran orang tua di MA Darul Arqam (p=0,000, φ=0,403) terhadap perilaku seksual berisiko santri sedangkan siswa di SMAN 6 tidak terdapat pengaruh orang tua (p=0,472) terhadap terhadap perilaku seksual berisiko. Adapun pengaruh pemahaman agama (p=0,027, φ=0,134), teman sebaya (p=0,000, φ=0,339) dan penggunaan media sosial p=0,035, φ=0,128) di SMAN 6 terhadap perilaku seksual berisiko pada siswa sedangkan santri di MA Darul Arqam menunjukkan tidak ada pengaruh pemahaman agama (0,811), peran teman sebaya (0,702) dan media sosial (0,063) terhadap perilaku seksual berisiko pada santri.

Detection of serum antibodies to M. leprae Major Membrane Protein-II in leprosy patients from Indonesia

Abstract: Summary Background Sero-diagnostic methods are the easiest way of diagnosing an infectious disease in developing countries. In leprosy, phenolic glycolipid-1 (PGL-I) based methods for the detection of leprosy are currently available, but the use of these methods has been hindered due to the inherent problems of sensitivity. We previously showed that antibodies to Major Membrane Protein-II (MMP-II) derived from Mycobacterium leprae could be used to diagnose leprosy in Japan. Methods Sera from patients and healthy individuals were collected with informed consent and the anti-MMP-II antibody levels of the sera were measured by enzymelinked immunosorbent assay. The study was conducted at South Sulawesi and Bali, in Indonesia. The study population included 40 each of multibacillary leprosy and paucibacillary leprosy patients, 30 tuberculosis and 16 patients with typhoid. Results We evaluated the anti-MMP-II antibody levels in Indonesian individuals. The cut-off value was determined from receiver operator characteristic curve as 0·124 using the O.D. titers for patients with multibacillary leprosy, so that the sensitivity of the test was 97·5% and the specificity taking healthy individuals as controls was 98·4%. Using the determined cut-off values, 98% of multibacillary (MB) leprosy and

Day length as a key factor moderating the response of coccolithophore growth to elevated pCO2

Abstract: The fate of coccolithophores in the future oceans remains uncertain, in part due to key factors having not been standardized across experiments. A potentially moderating role for differences in day length (photoperiod) remains largely unexplored. We therefore cultured four different geographical isolates of the species Emiliania huxleyi, as well as two additional species, Gephyrocapsa oceanica (tropical) and Coccolithus braarudii (temperate), to test for interactive effects of pCO2 with the light : dark (L : D) cycle. We confirmed a general regulatory effect of photoperiod on the pCO2 response, whereby growth and particulate inorganic carbon and particulate organic carbon (PIC : POC) ratios were reduced with elevated pCO2 under 14 : 10 h L : D, but these reductions were dampened under continuous (24 h) light. The dynamics underpinning this pattern generally differed for the temperate vs. tropical isolates. Reductions in PIC : POC with elevated pCO2 for tropical taxa were largely through reduced calcification and enhanced photosynthesis under 14 : 10 h L : D, with differences dampened under continuous light. In contrast, reduced PIC : POC for temperate strains reflected increases of photosynthesis that outpaced increases in calcification rates under 14 : 10 h L : D, with both responses again dampened under continuous light. A multivariate analysis of 35 past studies of E. huxleyi further demonstrated that differences in photoperiod account for as much as 40% (strain B11/92) to 55% (strain NZEH) of the variance in reported pCO2-induced reductions to growth but not PIC : POC. Our study thus highlights a critical role for day length in moderating the effect of ocean acidification on coccolithophore growth and consequently how this response may play out across latitudes and seasons in future oceans.
