Quantitative UV-spectrophotometry estimation of risperidone using hydrotropic solubilization phenomenon

The aim of present study was to develop simple and economical UV- pectrophotometric method for estimation of Risperidone using Area Under Curve (AUC) technique with the application of hydrotropic solubilisation phenomenon. Aqueous urea solution (30% v/v ) was used as hydrotropic agent for solubilising risperidone. The method is based upon integration of area under curve for analysis of risperidone in the wavelength range of 265.0 - 287.40 nm. The drug followed linearity in the concentration range of 4 - 24 g/mL with correlation coefficient value r 2 > 0.99. Proposed method was validated for accuracy, precision, repeatability and ruggedness as per ICH guidelines. The proposed method was applied for qualitative and quantitative estimation of risperidone in pharmaceutical formulation and results were found in good agreement with the label claimed. This developed method can be used for routine analysis of Risperidone in bulk and tablets

A Temporal -omic Study of Propionibacterium freudenreichii CIRM-BIA1T Adaptation Strategies in Conditions Mimicking Cheese Ripening in the Cold

Propionibacterium freudenreichii is used as a ripening culture in Swiss cheese manufacture. It grows when cheeses are ripened in a warm room (about 24°C). Cheeses with an acceptable eye formation level are transferred to a cold room (about 4°C), inducing a marked slowdown of propionic fermentation, but P. freudenreichii remains active in the cold. To investigate the P. freudenreichii strategies of adaptation and survival in the cold, we performed the first global gene expression profile for this species. The time-course transcriptomic response of P. freudenreichii CIRM-BIA1T strain was analyzed at five times of incubation, during growth at 30°C then for 9 days at 4°C, under conditions preventing nutrient starvation. Gene expression was also confirmed by RT-qPCR for 28 genes. In addition, proteomic experiments were carried out and the main metabolites were quantified. Microarray analysis revealed that 565 genes (25% of the protein-coding sequences of P. freudenreichii genome) were differentially expressed during transition from 30°C to 4°C (P<0.05 and |fold change|>1). At 4°C, a general slowing down was observed for genes implicated in the cell machinery. On the contrary, P. freudenreichii CIRM-BIA1T strain over-expressed genes involved in lactate, alanine and serine conversion to pyruvate, in gluconeogenesis, and in glycogen synthesis. Interestingly, the expression of different genes involved in the formation of important cheese flavor compounds, remained unchanged at 4°C. This could explain the contribution of P. freudenreichii to cheese ripening even in the cold. In conclusion, P. freudenreichii remains metabolically active at 4°C and induces pathways to maintain its long-term survival

FCC-ee: The Lepton Collider: Future Circular Collider Conceptual Design Report Volume 2

In response to the 2013 Update of the European Strategy for Particle Physics, the Future Circular Collider (FCC) study was launched, as an international collaboration hosted by CERN. This study covers a highest-luminosity high-energy lepton collider (FCC-ee) and an energy-frontier hadron collider (FCC-hh), which could, successively, be installed in the same 100 km tunnel. The scientific capabilities of the integrated FCC programme would serve the worldwide community throughout the 21st century. The FCC study also investigates an LHC energy upgrade, using FCC-hh technology. This document constitutes the second volume of the FCC Conceptual Design Report, devoted to the electron-positron collider FCC-ee. After summarizing the physics discovery opportunities, it presents the accelerator design, performance reach, a staged operation scenario, the underlying technologies, civil engineering, technical infrastructure, and an implementation plan. FCC-ee can be built with today’s technology. Most of the FCC-ee infrastructure could be reused for FCC-hh. Combining concepts from past and present lepton colliders and adding a few novel elements, the FCC-ee design promises outstandingly high luminosity. This will make the FCC-ee a unique precision instrument to study the heaviest known particles (Z, W and H bosons and the top quark), offering great direct and indirect sensitivity to new physics

The 1994 plague epidemic of India: Molecular diagnosis and characterization of Yersinia pestis isolates from Surat and Beed

PCR analysis of formalin-fixed human autopsy tissues, rodent tissues, fleas and bacterial isolates from pneumonic patients from the 1991 plague epidemic confirmed the presence of the f1 and pla genes of Yersinia pestis in these samples, Several Y. pestis isolates from the epidemic areas were studied in respect of their plasmid profile, expression of FI antigen and ribotype pattern, All the three plasmids known to be associated with virulence were present in the Surat isolates of Y. pestis. Presence of the F1 antigen, clasically used for diagnosis of Y. pestis infection, was demonstrated by immunoblotting. All the Indian isolates from the 1994 epidemic showed an identical ribotype profile, This profile, however, was different from those of Y. pestis isolates tested from other regions of the world. Upon digestion with EcoRI and EcoRV, and probing with E. coli 16S and 23S rRNA genes, DNA from these Y. pestis isolates gave two distinct profiles which, taken together, suggest that the present Indian isolates represent a new ribotype. The presence of Y. pestis signature genes in 5 out of 7 fleas collected from rodents in the affected areas, and the occurrence of the same ribotype in the Y. pestis isolates from domestic rodents, sylvatic rodents and the patients are strongly indicative of a clonal origin of this Indian strain and an epidemiological linkage among wild rodents, domestic rats and humans in the epidemic are
