Astaxanthin biosynthesis in Haematococcus pluvialis was enhanced by different monochromatic light patterns. Among the monochromatic light, red light was found most effective for facilitation of astaxanthin - up to 0.055 µg mL-1, followed by blue light, while the biosynthesis of astaxanthin in unfiltered white fluorescent light was found to be 0.04 µg mL-1. Astaxanthin use as drawn from Haematococcus, will expand not only in the consumer market, but also in the worldwide medical market, therefore, an optimal biosynthesis method for astaxanthin production is important.

Ethylenediurea (EDU) was applied as soil drench in two Indian cultivars of black gram (Vigna mungo L. cv. Azad-1 and BHU-1) and its ameliorating effect against ozone (O₃) stress was studied on selected growth, physiological, biochemical, and yield characteristics. The study site experienced a high O₃ concentration of 41.3–59.9 ppb during the experimental period. It was found that growth parameters showed positive impact on plants treated with EDU and yield attributes were also higher than that of non-EDU-treated ones. Significant increments in ascorbic acid and protein contents were observed in EDU-treated plants as compared to control plants. Lipid peroxidation, however, showed a reverse trend in both the cultivars. Photosynthetic efficiency increased by EDU treatment as depicted by higher values for photosynthetic rate (Ps) and Fv/Fm ratio. EDU-treated plants had more efficient antioxidant enzyme defense system with higher SOD and POX activities. Both the cultivars showed differential response against O₃ and cultivar BHU-1 proved to be resistant as compared to Azad-1. This investigation proves the usefulness of EDU as a biomonitoring tool against O₃ for the remote areas having higher concentrations of O₃ and problem of frequent electricity failure.

The present study examines the research output and citation analysis in the field of Oncology, a branch of medical science which deals with the study and treatment of tumours, what we commonly know as cancer. Cancer as a disease is not confined to a particular region or a country, but is a global phenomenon and is still beyond the complete understanding and control of medicos. Research in the field of biomedical sciences in general and oncology is particular is undertaken at global level with almost each country contributing its bit in understating and control of disease. The study makes an empirical assessment of the research output and growth in the field of oncology at continental level for the period 2003-2012 and evaluates the aspects like research growth, citation analysis, h-Index etc. Data for the present study has been retrieved from the SCImago Journal and Country Ranking, which is totally based on the SCOPUS data source. Findings: - A total of 310593 research papers were published across six continents of the world during the period 2003-2012. Europe emerged the largest continent with its publication share of (124598, 40.11 %). Europe is followed by North America with its share percentage of (102897, 33.12 %) and Asia with (70555, 22.71 %). The contribution of Oceania, South America & Africa to the world oncology research is not that encouraging, as such there is greater need to promote oncology research in these continents. African contribution to global oncology research during the period remained (2215, 0.71 %), South American (3009, 0.96 %) and Oceania contributed (7319, 2.35 %). Oncology research publication on average during the period of study grew annually at 8.15 %, while as at continental level Africa registered highest annual publication growth of 19.08 %. North America and Europe are the only continents which recorded publication's growth below the average global growth.

In plant sciences, the prodigious significance of micronutrient is unavoidable since plant relies primarily on micronutrient as it has profound influence on array of plant activities. Although micronutrients are abundantly present in the soil but plants usually acquire them in relatively trace amounts; hence, regarded as tracer element. B, Cu, Fe, Mn, Zn are such micronutrients required in minute amounts by plants but inexorably play an eminent role in plant growth and development. Plant metabolism, nutrient regulation, reproductive growth, chlorophyll synthesis, production of carbohydrates, fruit and seed development, etc., are such effective functions performed by micronutrients. These tracer elements when present at adequate level, elevate the healthy growth in plant physiological, biochemical and metabolic characteristics while their deficiency promotes abnormal growth in plants. Prevalence of micronutrient deficiency has become more common in recent years and the rate of their reduction has further been increased by the perpetual demands of modern crop cultivars, high soil erosion, etc. On the basis of present existing condition, it is not difficult to conclude that, the regular increment of micronutrient deficiency will be mostly responsible for the remarkable degradation in substantiality of agricultural crops somewhere in near future and so that this issue has now been the subject of intensified research among the breeder, ingenuities and expertise of science. These micronutrients can also be proven toxic when present at accelerated concentrations and such toxicity level endangers the plant growth. Taking this into consideration, the current review unfolds the phenomenal participation of micronutrients in plant sciences and gives a brief overview of the current understanding of main features concerning several micronutrient acquisitions in agricultural crop plants.

The alkaloids dehydrocorydalmine and oxyberberine isolated from Argemone mexicana were assessed against spore germination of some fungi, e.g., Alternaria cajani, Bipolaris sp., Helminthosporium sp., Fusarium udum and Curvularia sp. While dehydrocorydalmine inhibited 100% spore germination of the fungi Helminthosporium sp. and Curvularia sp. at 5 000 ppm, oxyberberine showed similar activity against spore germination of Bipolaris sp. and Curvularia sp. All the five fungi were significantly inhibited at 1 000 to 5 000 ppm concentrations.

The present study evaluates the possible radioprotective effect of Grewia asiatica fruit (rich in anthocyanin, carotenes, vitamin C, etc.) pulp extract (GAE) on cerebrum of Swiss albino mice exposed to 5 Gy gamma radiation. For this, healthy mice from an inbred colony were divided into four groups: (1) Control (vehicle treated), (2) GAE treated – mice in this group were orally supplemented with GAE (700 mg/kg. b.w. /day) once daily for fifteen consecutive days, (3) Vehicle treated irradiated mice, and (4) GAE + Irradiated – Mice in this group received distilled water orally equivalent to GAE (700 mg/kg. b.w./day) for fifteen days consecutively. Mice were sacrificed at various intervals viz. 1–30 days. Radiation-induced augmentation in the levels of lipid peroxidation of mice cerebrum was significantly ameliorated by GAE pretreatment. Radiation-induced depletion in the level of glutathione and protein was prevented significantly by GAE administration.

Background: The superficial palmar arch (SPA) and deep palmar arch (DPA) provide the dominant vascular supply to the hand. The SPA is considered to be highly variable and can be classified as either complete or incomplete. The simplest definition states that the anastomosis between the vessels contributing to the arch represent a complete arch, while an incomplete arch is described as characterised by an absence of anastomosis between the vessels contributing to it. This study aimed to describe the anatomical landmarks, formation and branching patterns of the SPA and DPA. In this study, the SPA and DPA were dissected in 50 specimens (n = 100 adult hands), respectively. Materials and methods: A complete SPA was observed in 92% of specimens and classified into three types. In Type A (44%), the SPA was formed by the anastomosis of the superficial palmar branch of the radial artery with the ulnar artery. Type B (46%) was formed by the ulnar artery alone and Type C (2%) was formed by anastomosis of the ulnar artery with the superficial palmar branch of the radial artery and the persistent median artery. Results: An incomplete SPA was observed in 8% of the specimens and divided into three types formed by the radial and ulnar arteries. The DPA was divided into five types viz. Type G (72%), where the DPA was formed by anastomosis of the deep palmar branch of the radial artery (DPBRA) with the deep palmar branch of the ulnar artery (DPBUA). Type H (12%), was formed by anastomosis of the DPBRA, the DBUA and the interosseous artery. Type I (8%), was formed by the anastomosis of the DPBRA with the superior and inferior DPBUA. Type J (4%), the deep ulnar artery had two branches whereby either one branch anastomosed with the DPBRA to form the DPA. Type K (4%), the DBUA exhibited two deep branches with one branch anastomosing with the DPBRA to complete the DPA. Conclusions: The interosseous artery anastomosed with either the DPA or the additional DPBUA. Knowledge of the variability of the SPA and DPA is crucial for safe and successful hand surgeries.

The bacterial strains, Paenibacillus sp. (AY952466) and Bacillus cereus (DQ002384), have proven capacity to degrade lignin and pentachlorophenol. In the present study, both strains were screened at different concentrations of phenol on mineral salt agar medium in the presence of glucose. At optimized condition (pH 7.5 ± 0.2,37 ± 1°C, 120 rpm, 1% glucose w/v), it was observed that both Paenibacillus sp., B. cereus and its mixed culture degraded phenol (500 mg/l) up to 53.86%, 91.63% and 67.76% within 168 h of incubation, respectively. Phenol degradation was routinely monitored spectrophotometrically and further confirmed by HPLC. Catechol and 2-hydroxy muconic semialdehyde were identified as intermediate products from degraded samples using GC-MS. It was also observed that, in the absence of glucose, bacterial strains were unable to utilize phenol indicating the phenomenon of co-metabolism.
