Growing numbers of antibiotic-resistant bacteria are putting this golden era of medicine at risk and stresses the need for regular monitoring of antibiotic susceptibility, and developing a new design being active against resist pathogens. In this view seven Schiff base ligands of Cephalosporin group antibiotics were synthesized by their condensation with salicylaldehyde in equimolar ratio. Complexes of these Schiff bases with Pd (II) metal were synthesized in 1:2 stoichiometric ratio. The complexes were formulated as [Pd(L)2].3H2O, where L is Schiff base of seven different cephalosporin antibiotics. Complexes were characterized by elemental analyses, molar conductance, UV-Visible, FT-IR, 1H-NMR, 13C{1H}-NMR, 2D-NMR and ESI-Mass spectrometry. Schiff bases were coordinated with metal through phenolic oxygen and azomethine-N, giving simple square planar geometry to complexes. Complexes were tested for antibacterial activity and MIC against gram-negative bacteria E. coli and gram positive bacteria S. aureus and were found more potent than Schiff bases and precursor antibiotics.

Gum odina, a natural polymer of carbohydrate moiety, has already been shown its potential as pharmaceutical excipient as a binder in tablet dosage form and also as an emulsifying agent but very little data are available regarding the use of it as controlled release polymer. In the present study the objective was to investigate the potential use of gum odina as natural release retarding material in sustained release drug delivery system (matrix tablet) using tramadol hydrochloride as a model drug. Tablet containing tramadol hydrochloride was prepared using gum odina and further coated with Eudragit L 100 to prevent its release in stomach. The prepared tablets were evaluated for physical characterization and in-vitro drug release. The results of this study has proven the suitability of using gum odina as an alternative to existing natural polymer in the field of controlled delivery of drug with a significant effect on drug release and desired release rate of drug from tablets.

Aegle marmelos, a plant having tremendous therapeutic potential, the importance seems largely due to its medicinal properties and all the parts viz. roots, leaves, fruits, bark and seeds are used for curing human ailment. In the present investigation, the anticlastogenic potential of hydromethanolic Aegle marmelos (AM) leaves extract has been evaluated using in vivo Micronucleus assay in Swiss albino mice. Cyclophosphamide (CP), a well known mutagen was given intraperitoneal (i.p.) injection at the dose of 50 mg/kg bodyweight (b.w.). AM leaves extract at the doses of 450, 675, 900 mg/kg b.w. provided protection when given 24 hrs. prior to CP administration. In CP treated animals, a significant induction of micronucleus was recorded and in different AM extracts supplemented groups, a dose dependent significant decrease in CP induced clastogenicity was observed which was statistically significant (p

Weeds are considered troublesome and undesirable component leading to enormous reduction in crop yield, wastages of resources and human energy. An attempt has been made to evaluate the effect extracts of four obnoxious weeds, Argemone mexicana, Parthenium hysterophorus, Cyperus rotundus Lin., Verbesina encelioides on the mitotic activity of germination of mung beans. Metabolites were extracted in methanol, acetone , hexane and distilled water using soxhlet extraction and assayed for the presence of bioactive metabolites. Presence of terpenes, flavonoids and quinines were observed in the methanol extract of all the weeds and hexane extracts indicated the presence of glycosides and flavonoids. Based on percentage inhibition studies, it was found water extracts followed by acetone extracts for all the weeds were most potent as a growth inhibitor. Argemone Mexicana and Parthenium hysterophoresus were found to be most potent in inhibiting mitotic activity and growth although statistical significance (P

The observational study was a retro-selective, unicenter, nonrandomized study to evaluate the clinical safety and efficacy of the stainless steel and cobalt-chromium alloy stent. Use of the cobalt-chromium alloy in place of stainless steel offers enhanced visibility and radial strength with thinner structural elements. The study enrolled 128 patients with symptomatic ischemic heart disease attributable to de novo or restenotic nonstented native lesions of a single vessel amenable to percutaneous stenting. The primary composite end point was the incidence of major adverse cardiac events (death, myocardial infarction, emergency bypass surgery, or target lesion revascularization) 365 days after PCI. The mean age of patient was 56.17 ± 10.43 years, with 50.81% and 47.36% of unstable angina patient. No difference in most clinical angiographic characteristic between two groups. At 1 month follow up there was no significant difference between two groups (p = 0.96). The individual clinical component showed no difference in occurrence of death (p = 0.29), MI (p = 0.29) and TLR (p = 0.96) at end of 6 month. At 1 year MACE occurred 8.1% in cobalt chromium group and 14.0% in stainless steel stent (p = 0.31). Rate of TLR was 0 % in cobalt chromium group and 3.5% in stainless steel stent (p = 0.14). The incidence of restenosis was 3.27 % in cobalt chromium group and 7.01% in stainless steel stent (p = 0.35).

Securinega leucopyrus (Willd.) Muell has long been used by the tribes of Sri Lanka traditionally known as ‘Katupila’and also in India as ‘Humri’. Common in scrub jungls, limited to India, Sri Lanka and Burma. DNA fingerprinting for cultivar or varietal identification has become an important tool for genetic identification in plant breeding and germplasm management.Several different PCR based techniques have been developed during the last decade, each with specific advantages and disadvantages. The Random Amplified Polymorphic DNA (RAPD) marker technique is quick, easy and requires no prior sequence information.Pharmacognostical evaluation of leaf and stem of Securinega leucopyrus (Willd.) already established but no research work have been established on its roots and DNA fingerprints; for the first time leaf samples were subjected to fingerprints and studied the pharmacognostical aspects of roots. Pharmacognostical study showed that presence of oil globules, rosette crystals and uni to multiserriate medullary rays. DNA finger prints showed that OPC 6, OPD 8 and OPB 10 showed that merging 2 bright bands and one light band.

The contamination of processed or unprocessed drinking water by pathogenic bacteria has been reported worldwide. Even though a high incidence of waterborne diseases have been well documented, enterobacteriaceae is an under acknowledged pathogen of concern to public health in India. The study was aimed to isolate and biochemically characterize Enterobacteriaceae as well as to determine  antibiotic sensitivity pattern and primer designing specific to their signature gene sequences for rapid detection by PCR methods. Total plate count was determined in potable water sample collected from three different sites of Jaipur city and was found to be nearly equal or more than 105 cfu/ ml. Enterobacteriaceae were enumerated using the most probable number method (MPN index). Enterobacteriaceae (n = 36), randomly isolated from three sites, were identified, biochemically characterized and were screened for sensitivity to 9 antimicrobials by the disk diffusion method. The isolated bacteria had shown variable susceptibility and resistance patterns in response to different antibiotics used in the study. Polymerase chain reaction based methods can be a powerful molecular technique for rapid, sensitive and specific detection. Hence, in the present study primers were also designed specific to virulence signature sequences and their specificity was assessed by BLAST.

The objective of this research work was to formulate and evaluate the floating drug delivery system containing Pantoprazole sodium sesquihydrate as a model drug and to optimize its drug release profile. Pantoprazole sodium tablets were prepared by direct compression technique. Formulations contained Xanthan gum, PVP K30 and gas generating agent such as sodium bicarbonate and citric acid were taken as independent variables. The physical parameters of the tablets were characterized and were found within the limits. By comparing dissolution profiles of different formulations, the formulation F5 was considered as a better formulation. The drug release from all the formulations was found to follow zero order kinetics and Peppas modeling. The diffusion exponent of formulations was found (n

Dermatophytosis is currently treated with the commercially available topical and oral antifungal agents in spite of the existing side effects. Treatment of these cutaneous infections with secondary metabolites produced by wild plant is considered as an alternative approach. Exploring the unexplored aspect of the wild plants for developing antidermatophytic drugs is a novel attempt which needs further investigation. Study aims to screen eleven wild medicinal plants possessing antifungal activity against the clinical fungal isolates from dermatophytic patients. The methanolic plant extract were analyzed by well diffusion assay and phytochemical characterization of the active ingredient were determined possessing mycocidal activity. Aspergillus sp. was effectively controlled by the extracts of C.roseus , R.communis, T. cordifolia, J. curcas, C. longa; Curvularia sp. by T. cordifolia, R. communis , T. erectus , C. longa; Cladosporium sp. C. roseus  , R. communis , L. inermis , T. erectus, A. nilotica; Microsporium sp. by C. roseus, R. communis, J. curcas, L. inermis, A. nilotica  and Penicillium sp. by A. nilotica, R. communis, C. longa, T. occidentalis and T. erectus . Maximum Alkaloid was recovered from T. peruviana, Saponin in R. communis and C. roseus, Flavanoid from R. communis, Tannin in T. erectus and C.  roseus and phenols from L. inermis. Methanolic plants extracts of Catherenthus reseus, Riccinus communis, Tagetus erectus, Acacia nilotica, Lawsonia inermis and Thuja occidentalis were found to be significantly controlling the test fungi.  Data revealed that plants possessing higher phenol, tannin and saponin show antifungal activity.

Extended spectrum -lactamases are plasmid mediated. These plasmids produce enzymes that hydrolyze broad spectrum cephalosporins and monobactams. They acquire resistance prevalently through plasmid encoded. Study determines plasmids and their correlation with drug resistance against many antibiotics that limits their therapeutic implications. Bacteriological analysis of 50 samples susceptible for ESBL was conducted. The samples subjected to susceptibility tests and detection of ESBL. Plasmid DNA isolation of all the ESBL positive strains of E. coli was done by alkali-lysis method. Finally the presence of plasmid was correlated with susceptibility to beta lactam drugs. ESBL was detected in 56% (28 out of 50 isolates). Maximum ESBL incidence recorded of E. coli (30 %) followed by Klebseilla pnemoniae (18%) and Pseudomonas aeruginosa (8 %). ESBL exhibited high-level resistance to beta lactam antimicrobial agents like  Amoxiclave (56%), Cefuroxime (54%), Cephotaxime (54%), Ceftriaxon (50%), Ceftazidime (46%) and Cefixime (36%). During plasmid profiling of eight isolates of ESBL E. coli showed one to four definite bands indicating the presence of different plasmids. ESBL’s constitute a growing class of plasmid-mediated -lactamases which confer resistance to broad spectrum β-lactam antibiotics. Incidence of ESBL is continuously increasing globally with limited treatment alternatives and formulates treatment policy. Moreover, restricted use of the third generation cephalosporins lead to withdrawal of selective pressure and use of lactam and -lactamase inhibitor combinations may exert reverse mutation on these enzymes. There is a strong correlation between the number of plasmids harbored by an isolate and drug resistance.
