(1)Aloe-Barbadensis Mill (Liliaceae) is used in the traditional medicine of Mexico and other countries for anti-inflammatory and cosmetic purposes (Diez-Martinez 1981, Grindlay and Reynolds 1986). Two components are obtained from the fresh leaves of Aloe-Barbadensis, a bitter yellow juice (exudate), which drains from the transversally cut leaves used as a laxative (Ishii et al 1990) and a mucil...

ADP-glucose pyrophosphorylase (AGP) was purified from tomato (Lycopersicon esculentum Mill.) fruit to apparent homogeneity. By sodium dodecyl sulfate-polyacrylamide gel electrophoresis the enzyme migrated as two close bands with molecular weights of 50,000 and 51,000. Two-dimensional polyacrylamide gel electrophoresis analysis of the purified enzyme, however, revealed at least five major protei...

Investigations were made concerning the number and properties of amylase in sugarcane leaves. Enzymes were extracted froin leaf samples which had been frozen, lyophilized, and ground to a fine powder. Techniques of differential solubihty, gel filtiation, and papei electrophoresis were employed to remove amylase from the crude extracts. Solubility studies showed that amylase was moderately preci...

AIM: To evaluate the effect of lid scrubbing using a gel combining different natural extracts on ocular signs and symptoms dry eye patients. METHODS: A retrospective study was performed 19 patients (51.1±16.0y). Non-invasive tear break-up time, meniscus height, meibomian gland loss, lipid layer thickness, conjunctival redness, corneal staining, surface disease index (OSDI), pain intensity were ...

Leaf senescence, the final stage of leaf development, is a complex and highly regulated process that involves a series of coordinated actions at the cellular, tissue, organ, and organism levels under the control of a highly regulated genetic program. In the last decade, the use of mutants with different levels of leaf senescence phenotypes has led to the cloning and functional characterizations...

Activity of the enzyme ADPglucose pyrophosphorylase is known to be reduced in maize (Zea mays L.) endosperm mutants at two independent loci, Shrunken-2 (Sh(2)) and Brittle-2 (Bt(2)). Spinach leaf ADPglucose pyrophosphorylase has previously been shown to comprise two subunits of 51 and 54 kilodaltons. Anti-bodies raised to each of the two subunits of spinach leaf ADPglucose pyrophosphorylase wer...

Nitrate reductase (NR)-inactivating proteins from corn roots (Wf-9 x 38-11) and rice cell suspension cultures were tested against a partially purified NR obtained from corn leaves (W64A x W182E). The corn protein was purified 921-fold and the rice protein, 1,660-fold using standard purification procedures. Approximate molecular weight values were 75,000 for the corn protein, and 150,000 for the...

biology teachers at Taman Mulia Kubu Raya School, project-based student worksheets (LKPD) in making hand sanitizer gels and also did not have experience kesum leaf gels. This study aims to develop a LKPD manufacture of gel on biotechnology materials. Research is the development Thiagrajan with amodified 4D model into 3D. that are developed feasible based percentage eligibility for media, materi...

This investigation examines the possibility for nitrite chemical preservative to be delivered in meat cured products. Potassium was encapsulated delignified leaf celery and spinach placed on surface of meat. The delignification produces edible tubular cellulose (ETC) with 10 fold increased pore volume. encapsulation delivery using vegetable has been achieved both ETC ETC/Starch gel (SG) composi...

Antioxidants for facial skin care would be better formulated in a topical form because the active substances will interact longer with skin. Indonesia is known its wealth of natural ingredients that are useful as antioxidants. Research related to has been widely carried out and good content The antioxidant herbal plants secondary metabolites, namely flavonoids, alkaloids, phenolic compounds, ca...
