Abstract
Background Necrotizing fasciitis (NF) is a life-threatening condition requiring urgent attention. It is clinically difficult to diagnose, linked to severe systemic toxicity, and has poor prognosis. In 2001, Andreasen and coworkers described the "Finger test" for the diagnosis of NF. Subsequent studies have suggested early recognition and management of NF. In this study, we compare the LRINEC-Laboratory Risk Indicator for Necrotizing Fasciitis-scoring system with the "Finger test" and histopathological examination for diagnosis of NF. Results In our study, LRINEC scoring system and Finger test are statistically significant in the diagnosis of NF. Males are more frequently affected, and the most common organism causing NF is Staphylococcus . Histopathology remained the gold standard for diagnosis of NF, while LRINEC score and Finger test were good diagnostic tools for early diagnosis, with sensitivities of 83.33 and 86.11%, respectively. Conclusion LRINEC laboratory-based scoring system is easy and reliable diagnostic tool though histopathology remains the gold standard. There is statistically significant correlation between histopathology and laboratory criteria. LRINEC test is independently better than bedside Finger test alone or combined LRINEC and bedside Finger test.

Abstract
Seventy-six plant extracts including methanolic and successive water extracts from 37 Indian medicinal plants were investigated for acetylcholinesterase (AChE) inhibitory activity (in vitro). Results indicated that methanolic extracts to be more active than water extracts. The potent AChE inhibiting methanolic plant extracts included Withania somnifera (root), Semecarpus anacardium (stem bark), Embelia ribes (Root), Tinospora cordifolia (stem), Ficus religiosa (stem bark) and Nardostachys jatamansi (rhizome). The IC(50) values obtained for these extracts were 33.38, 16.74, 23.04, 38.36, 73.69 and 47.21mug/ml, respectively. These results partly substantiate the traditional use of these herbs for improvement of cognition.

Abstract
Successive extracts of Tribulus terrestris prepared using petroleum ether, chloroform, 50% methanol and water were tested for anthelmintic activity in-vitro using the nematode Caenorhabditis elegans. The activity could be detected only in 50% methanol extract which on further bioactivity guided fractionation and chromatographic separation yielded a spirostanol type saponin, tribulosin and beta-sitosterol-D-glucoside. Both the compounds exhibited anthelmintic activity with ED50 of 76.25 and 82.50 microg/ml respectively.

Abstract
The essential oil of Ocimum sanctum and eugenol, tested in vitro, showed potent anthelmintic activity in the Caenorhabditis elegans model. Eugenol exhibited an ED(50) of 62.1 microg/ml. Eugenol being the predominant component of the essential oil, is suggested as the putative anthelmintic principle.

Abstract
Glycine is unique among the amino acids in view of its symmetric nature. While the overall distribution of glycyl residues in the (phi, psi) plane is near-symmetric, there can be certain preferences for the individual conformations. An analysis of the observed glycyl conformations in 70 proteins has been carried out to find the influence of residues adjoining the glycyl residues. For this purpose, the (phi, psi) plane has been divided into two regions: the region in which phi is negative and the region in which phi is positive. The analysis is done in terms of the number of conformations occurring in these regions. It has been found that while the overall percentage distribution of glycyl residues between the positive and the negative phi regions is 54:46, the distribution shows asymmetry when the examples are sorted out in terms of X-Gly and Gly-Y doublets. The asymmetry becomes more prominent when the data are sorted out into triplets X-Gly-Y. Using the available information, it has been possible to designate 25 triplets as P-predominant and 19 as N-predominant. An examination of P-predominant triplets for possible occurrence in beta-bends having one of the conformations in the positive phi region shows that only 25% are of this nature. Thus, the P-preference of P-predominant triplets is not an outcome of the bend formation alone and must be an inherent property of these triplets.

Abstract
The torsional potential functions Vt(phi) and Vt(psi) around single bonds N--C alpha and C alpha--C, which can be used in conformational studies of oligopeptides, polypeptides and proteins, have been derived, using crystal structure data of 22 globular proteins, fitting the observed distribution in the (phi, psi)-plane with the value of Vtot(phi, psi), using the Boltzmann distribution. The averaged torsional potential functions, obtained from various amino acid residues in L-configuration, are Vt(phi) = 1.0 cos (phi + 60 degrees); Vt(psi) = 0.5 cos (psi + 60 degrees) - 1.0 cos (2 psi + 30 degrees) - 0.5 cos (3 psi + 30 degrees). The dipeptide energy maps Vtot(phi, psi) obtained using these functions, instead of the normally accepted torsional functions, were found to explain various observations, such as the absence of the left-handed alpha helix and the C7 conformation, and the relatively high density of points near the line psi = 0 degrees. These functions derived from observational data on protein structures, will, it is hoped, explain various previously unexplained facts in polypeptide conformation.
