INTRODUCTION Treatment of the severe forms of acne vulgaris remains a challenge. Isotretinoin is a drug often used in these cases. Retinoids affect the mechanisms that play a role in the pathogenesis of acne, reduce the production of sebum and sizes of the sebaceous glands. However, isotretinoin appears to have undesirable side effects in the skin, mucous membranes and hair. AIM THE AIM OF TH...

Intra-caecal fermentation parameters in caecally ®stulated ponies offered ®brous diets of diverse botanical origin were examined in two experiments, A and B. In Experiment A three ponies were offered ca. 4 kg dry matter (DM) per day of either ground, pelleted hay cubes (HC), a 67:33 mix of oat hulls:naked oats (OH:NO) or a 75:25 mix of unmolassed:molassed sugar beet feed (SBF), whilst in Experi...

Adsorption capacity of 4-chloro-2-nitrophenol (4C2NP) onto nano-Ti02 from aqueous solutions wasinvestigated in a batch system by considering the effects of various parameters like contact time, nano-TiO2 dosage, initial pH and initial 4C2NP concentration. Optimum conditions for 4C2NP adsorptionwere found to be initial pH z 2, nano-TiO2 closer- 0.01 g and equilibrium time 1 h. The adsorptionkine...

INTRODUCTION Complications of diabetes can damage internal organs and the skin. Diabetic skin, irritated and dry, is susceptible to skin infections. However little is known about influence of emollients on biophysical changes in skin during diabetes. AIM To evaluate clinical skin changes after application of emollients with benfothiamine and Biolin prebiotic and to assess changes in biophysic...

Aspergillus niger FETL FT3, a local extracellular tannase producer strain that was isolated from one of dumping sites of tannin-rich barks of Rhizophora apiculata in Perak, Malaysia. This fungus was cultivated in 250 mL Erlenmeyer flask under submerged fermentation system. Various physical parameters were studied in order to maximize the tannase production. Maximal yield of tannase production, ...

Understanding process parameter interactions and their effects on mammalian cell cultivations is an essential requirement for robust process scale-up. Furthermore, knowledge of the relationship between the process parameters and the product critical quality attributes (CQAs) is necessary to satisfy quality by design guidelines. So far, mainly the effect of single parameters on CQAs was investig...

The amino acid sequences of cellulase from Bacillus subtilis (BSC) and that from an alkalophilic Bacillus sp. N-4 (NK1) show significant homology in most parts except for the C-terminal portions. Despite the high homology, the pH activity profiles of the two enzymes are quite different; BSC has its optimum pH at 6-6.5, whereas NK1 is active over a broad pH range from 6 to 10.5. In order to iden...

A potentiometric enzyme biosensor for the direct measurement of organophosphate pesticides was developed. The basic element of this enzyme biosensor was a pH electrode modified with an immobilized organophosphorus hydrolase layer formed by cross-linking OPH with bovine serum albumin and glutaraldehyde. Organophosphorus hydrolase catalyzes the hydrolysis of organophosporus pesticides to release ...

The present study focused on the production optimization of bacteriocin by Lactobacillus viridescence NICM 2167 followed by its purification and characterization. The bacteriocins are antimicrobial peptides produced by many Gram positive and Gram negative bacteria.The bacteriocin produced by LAB (lactic acid bacteria) received attention in recent years due to their potential application as natu...
