Metode Cepat Identifikasi Flavonoid dari Daun Ocimum sanctum L. (Selasih)
No full textA plant’s effectiveness as a herbal drug comes from its chemical content such as flavonoids. Flavonoids are useful for human body health. Therefore flavonoids content can be used as a marker from the usefulness of a plant, and rapid identification method of flavonoid is needed. The objective of the research was to get a rapid method of flavonoid content identification from Ocimum sanctum. The extraction, isolation and identification of flavonoids from Ocimum sanctum leaves has been done at Medical Chemistry laboratory Faculty of Medicine Universitas Padjadjaran in 2005. Flavonoids were extracted continually by 95% ethanol, were isolated with paper chromatography/cellulose TLC and 2% acetic acid, then continued with elucidation reagents: n-butanol–acetic acid–water, chloroform–acetic acid–water, forestall, 5%, 15%, 35% and 50% acetic acids. Flavonoids were identified with diagnostic reagents and ultraviolet light. Isolation with 2% and 35% acetic acids respectively gave two spots of flavonoids as flavon, FOAc-1 had Rf=0.69 and FOAc-2 had Rf=0.57. The other elucidation reagents gave one spot of flavonoid. In conclusion, isolation with 2% and 35% acetic acids respectively and identification with diagnostic reagent and ultraviolet light is a rapid method for identification of flavonoids content in Ocimum sanctu
Perancangan dan Pembuatan Catu Daya Digital Berbasis Mikrokontroler AT89S52
Get PDF18 HalamanSumber energi merupakan suatu faktor yang sangat dibutuhkan dalam
menjalankan suatu sistem. Salah satunya dalam sistem elektronika yang
menggunakan catu daya sebagai salah satu sumber energinya. Tidak semua
peralatan elektronika di desain dengan internal catu daya, sebagian dari peralatan
elektronika masih memerlukan ekstemal catu daya. Catu daya yang ada dipasaran
masih membingungkan masyarakat dalam pemakaiannya sehingga sering terjadi
kesalahan dalam pemberian tegangan ke suatu beban.
Oleh karena itu penulis memiliki ide merancang dan membuat catu daya
Digital Otomatis dan manual. Dengan dasar ini masyarakat akan lebih mudah
menggunakan tegangan DC sebagai sumber tegangan, karena catu daya ini dapat
menentukan besar tegangan outputnya sendiri. Dengan kata lain catu daya ini
bersifat otomatis yang membuatnya beda dari catu daya yang ada di pasaran. Energy source is a factor that very needed to operate a system. One of the
useful is in the electronic system that use power supply as one of the energy.
Much of the electronic tools do not design with internal power supply, most of
them still need external power supply. Power supply that sells in market still
make most people confuse to use it, so many mistakes that happen when the user
going to load the voltage.
Because of that , author have an idea to design and build a Digital Power
Supply . With this basic, people can be easily to use DC voltage as voltage
source, because this power supply can decide by itself how many voltage will use.
With the other words, this power supply have automatic character that make it
different from other power supply in market
Blunted Expression of PPARa in Mice with FABP-4 and -5 Deficiency under Acute Cold Exposure
Get PDFBrown Adipose Tissue (BAT) is a nonshivering thermogenesis organ during cold exposure. Peroxisomal proliferator activated receptor alpha (PPARa) is the member of the nuclear hormone receptor superfamily and primarily expressed in BAT and liver. PPARa is coordinated with uncoupling protein 1 (UCP1) to regulate fatty acid metabolism in BAT. Fatty acid binding protein (FABP)-4 and-5 play role in adaptive response under fasting and cold exposure. The purpose of this study was to investigate the expression of PPARa in mice with FABP4/5 deficiency (DKO). Wildtype (WT) and DKO mice were exposed to cold for 2 hours under fed or 20 hours-fasted conditions. BAT was collected and further mRNA level of PPARa was examined using quantitative real-time PCR. As the result, PPARa gene expression in WT mice were increased 50% and 100% in fed and fasted condition respectively after cold exposure. There was no alteration in PPARa expression in BAT of DKO mice. As conclusion, The functional FABP-4 and -5 are necessary to modulate PPARa gene expression in Brown Adipose Tissue under acute cold exposure Keywords: Acute cold exposure; FABP4; FABP5; Fasting PPARa</jats:p

No full textThis article discusses the concept of the maß╣úlaß©Ñah family in the perspective of mubadalah and its relevance to family resilience during the Covid-19 pandemic. The maß╣úlaß©Ñah family is a family whose members provide each other with primary needs that include physical and mental needs, and each others give rights and obligations. This paper is a literature research, with the descriptive-qualitative as method research and qiraÔÇÖah mubadalah as the approach. The results showed that the concept of maß╣úlaß©Ñah family in the perspective of qiraÔÇÖah mubadalah is that in principle it prioritizes the concept of mufaÔÇÖalah (kesalingan), meaning that there are no superior and no inferior parties in the family. In this case the maß╣úlaß©Ñah family indicators that can be displayed are at least several principles, namely the zawaj principle (prinsip saling berpasangan), the muÔÇÖadalah Principle (prinsip keadilan), the muwazanah principle (prinsip keseimbangan), the muÔÇÖawanah principle (prinsip saling menolong), the Principle of musyawarah, the Principle of taradhin min huma┬á (prinsip kerelaaan), and the Principle of muÔÇÖasyarah bil maÔÇÖruf (prinsip saling berkomunikasi/bergaul dengan baik). The author can conclude that the concept of the maß╣úlaß©Ñah family in the framework of mubadalah is that it has quite significant relevance if it is applied by every family, especially in the current Covid-19 pandemic
