  • Microbial fuel cells comprising the microorganism P. vulgaris, thionin as a mediator, and various mono- and disaccharides in an anodic compartment have been developed. A cathodic compartment containing a Pt electrode and Fe$(CN)_6^{3-}$ was separated from an anode by the Nafion membrane. From absorbance-time measurements, it was found that the absorbance of thionin was not altered by the addition of P. vulgaris, even in the presence of sugars. However, thionin was effectively reduced when P. vulgaris was present. These results differ substantially from the case of safranine O, a phenazine-derivative, indicating that thionin takes up electrons during the metabolic oxidation processes of carbohydrates. Maximum fuel cell efficiency was observed at 37 $^{\circ}C$, optimum temperature for the growth of P. vulgaris, and 0.5 V cell voltage was obtained, which indicates that the metabolism of the microorganism directly affects the efficiency. Thionin concentration was closely related to cell performance. When the charging-discharging characteristics were tested with glucose, galactose, sucrose, maltose, and trehalose as carbon sources, galactose was found to give the highest coulombic efficiency. Cell performance was almost fully recovered with only small degradation when glucose and sucrose were used in the repetitive operation. Current was maintained nearly twice as long for sucrose than in the case of glucose.

  • Artemisia vulgaris, one of the most religious plants in Nepal, is used in the treatment of various ailments. In this study, antioxidative activity of essential oil from A. vulgaris was evaluated, using different in vitro methods and antimicrobial activity by disc diffusion method against skin disease microorganisms such as Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, Candida albicans and Propionibacterium acnes. The essential oil exhibited a concentration-dependent antioxidant activity. It showed strong metal chelating activity with low reducing and antioxidant power. However, gradual increase in radical scavenging activity was obtained with increasing concentration and reaction time. It also possessed a broad spectrum of antimicrobial activity and notable susceptibility was observed against S. pyogenes and P. acnes.

  • 미세조류는 효율적으로 바이오매스를 증가시킬 수 있으며 유용한 생물학적 자원들을 축적할 수 있기 때문에 에너지 및 식품 생산 등 다양한 분야에서 유망한 자원으로써 주목받고 있다. 본 연구에서는 4종의 미세조류(Chlorella vulgaris, Mychonastes homosphaera, Coelastrella sp., Coelastrella vacuolata)를 선정하여 이들의 성장, CO2 동화, CO2 농도에 따른 미세조류의 지질 생성 특성을 분석하였다. 각 미세조류의 크기는 C. vulgaris가 가장 작았으며, M. homosphaera, C. vacuolata, Coelastrella sp. 순으로 큰 크기를 나타냈다. C. vulgaris는 다른 3종의 미세조류와 비교해서 크기가 가장 작으며 성장과 CO2 동화 속도가 가장 빠르게 나타났다. 또한, 초기 바이오매스가 증가함에 따라 CO2 동화 속도는 최대 9.62 mmol·day-1·l-1를 나타냈으며, 다른 3종의 미세조류(약 3 mmol·day-1·l-1)보다 3배 이상 높은 CO2 동화 속도를 보여주었다(p < 0.05). M. homosphaera를 제외하고 3종의 미세조류는 CO2 농도와 CO2 동화 비속도 사이에 양의 상관관계(positive correlation)를 나타냈다. 특히, C. vulgaris는 다른 3종의 미세조류와 비교해 더 높은 CO2 동화 비속도를 보여주었다(14.6 vs. ≤ 11.9 mmol·day-1·l-1). 4종의 미세조류는 CO2 농도가 증가함에 따라 지질 함량이 증가했으며 그 중에서 C. vulgaris는 최대 18 mg·l-1를 나타내 다른 3종의 미세조류(최대 12 mg·l-1)보다 최소 50% 이상 높은 지질 함량을 보여주었다. 4종의 미세조류 중 C. vulgaris가 효율적으로 CO2를 동화하며 다른 미세조류보다 높은 바이오매스와 지질 생산이 가능함을 시사한다.

  • Caenorhabditis elegans model system was used to investigate the antioxidant activity of Beta vulgaris L. (Chenopodiaceae) methanol extract. The methanol extract showed DPPH radical scavenging and superoxide quenching activity in a dose-dependent manner. The B. vulgaris methanol extract was measured for the activity of superoxide dismutase (SOD), catalase, and oxidative stress tolerance by using C. elegans, along with reactive oxygen species (ROS) level. In addition, to see that the regulation of the stress response gene is responsible for the increased stress tolerance of C. elegans treated by the methanol extract, SOD-3 expression was measured using a transgenic strain. As a result, the B. vulgaris methanol extract increased SOD and catalase activities, and decreased ROS accumulation, dose-dependently. Furthermore, the methanol extract-treated CF1553 worm showed higher SOD-3::GFP intensity than the control.

  • Introduction: Buthūr Labaniyya (Acne vulgaris) is a multifactorial disorder of the pilosebaceous units characterized by non-inflammatory and inflammatory clinical lesions. Several Unani medications have been used for centuries to treat acne. Objectives: Evaluation of safety and efficacy of Tila-i Muhāsā in patients with acne vulgaris Materials and Methods: This clinical study was conducted in patients with acne vulgaris. Patients applied Tila-i Muhāsā or 5% Benzoyl Peroxide (BPO) once daily for 6 weeks. Assessment of efficacy was carried out by Global Acne Grading System (GAGS) and Patient Global Assessment (PGA) scores. In addition, overall severity of acne was evaluated on a 5-point Cook's acne grading scale using photographic standards. Assessment of safety was performed through adverse drug reactions, local dermal tolerability, vital signs, and routine laboratory investigations. Results: A total of 60 patients (30 in each group) completed 6 weeks of treatment. The mean percentage reduction in GAGS score at 6 weeks from baseline in Unani group (66.97%) and BPO group (59.09%) was statistically significant (P<0.0001). After 6 weeks of therapy, the mean percentage reduction in PGA score compared to baseline in Unani group (57.44%) and BPO group (50.23%) was statistically significant (P<0.0001). No serious adverse events were reported in both groups; however, mild adverse events occurred more frequently in BPO group (30%) compared to Unani group (10%). Conclusion: Tila-i Muhāsā was found to be effective and safe in the treatment of acne vulgaris. However, further clinical studies with larger sample size and longer duration of therapy need to be conducted.
