The work describes synthesis of a bioactive molecule 2-(4-fluorophenyl)-4-(4-(4-methoxyphenyl)-5-(3-nitrophenyl)-4H-1, 2, 4-triazol-3-yl)quinoline. The characterization has been done with the help of various spectroscopic techniques followedby in-silico studies including various structural parameters viz. electrostatic potential, electrophilicity (ω), chemical potential(μ), chemical hardness (η), thermodynamic properties at various temperatures, Natural bond orbital (NBO), Non-linearoptical (NLO), electric dipole moment, polarizability and first static hyperpolarizability. Reactivity descriptors were alsoinvestigated to find out the sites liable for electrophilic and nucleophilic attack. The compound was also bio-evaluated for itsantimicrobial and antioxidant activity. It showed significant activity against S. typhi and a positive antioxidant activityshown by reduction in color with percentage inhibition of 89%

Synthesis, Spectroscopic & DFT studies of Novel N-((1H-benzo[d]imidazol-1-yl) methyl)-N-(2-(trifluoromethyl)phenyl)-4,5-dihydrothiazol-2-amine

Synthesis of N-((1H-benzo[d]imidazol-1-yl)methyl)-N-(2-(trifluoromethyl)phenyl)-4,5-dihydrothiazol-2-amine was done followed by its characterization by various spectral techniques. DFT studies of the compound were performed at B3LYP level to study various structural parameters and thermodynamic variables. The correlation of observed transitions with the electronic transitions had been done via NBO analysis. In addition to it, the HOMO and LUMO energy gaps and identification of sites liable for electrophilic and nucleophilic attack were done by MESP and ESP plots

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

Evaluation of phytonutrients and vitamin contents in a wild yam, dioscorea belophylla (prain) haines

The species studied was found to contain bioactive compounds comprising saponins (18.46 mg 100-1 g), alkaloids (0.68 mg 100-1 g), flavonoids (8.84 mg 100-1 g), tannins (4.2102 mg 100-1 g) and phenols (2.8103 mg 100-1 g). This yam contained vitamins such as ascorbic acid, riboflavin and thiamin. The importance of these chemical constituents is discussed with respect to the role of this Dioscorea species in herbal medicine

In vitro propagation of wild yams, Dioscorea oppositifolia (Linn) and Dioscorea pentaphylla (Linn)

In vitro propagation of two wild yams, Dioscorea oppositifolia and Dioscorea pentaphylla, is reported. Multiple shoots were initiated from nodal explants on Murashige and Skoog (MS) medium supplemented with 8.8 µM 6-benzylaminopurine (BAP) and 0.3% (w/v) activated charcoal. Root induction was also achieved simultaneously from the base of the shoots in the same medium. Individual shoots with a minimum of one node were excised and rooted in vitro on MS medium with 2.67 µM α-naphthaleneacetic acid (NAA) or ex vitro rooted on by treatment with 49 µM indole-3-butyric acid (IBA) for 30 min. Regenerants acclimatized in soil-rite showed vigorous shoot growth (within 2 weeks) and after 5 - 6 months were suitable for planting. Plantlets also developed tubers on MS medium with 8.8 µM 6-benzylaminopurine (BAP)

Conjunctival lymphoid hyperplasia presenting with bilateral panuveitis

PURPOSE: To report on a case of bilateral conjunctival lymphoid hyperplasia presenting with bilateral panuveitis in a female patient. DESIGN: Observational case report. METHODS: In this case excisional biopsy indicated lymphoid tissue. Immunohistochemistry showed a follicular architecture with appropriate zoning of B and T lymphocytes. RESULTS: Causes of panuveitis were considered and excluded based on a detailed history, physical examination, and laboratory investigations. The bilateral panuveitis resolved on topical corticosteroids and visual acuity returned to normal. CONCLUSIONS: Ocular adnexal lymphoproliferative lesions consist of a spectrum of disease entities, including reactive lymphoid hyperplasia, atypical lymphoid hyperplasia, and lymphoma. There are no established clinical criteria to differentiate between these lesions. This case highlights the importance of a thorough ophthalmic examination in these patients, as an intra-ocular inflammatory process may accompany the conjunctival findings. Futhermore, we advocate periodic follow-up examinations because of the small potential risk of developing ocular or systemic lymphoma in these patients
