This research was conducted to study the effects of bacteriophage application during tumbling on Salmonella populations in ground meat and poultry. Red meat trim and poultry were inoculated with a Salmonella cocktail to result in a contamination level of 7logCFU/g in ground products. A commercial preparation containing bacteriophages S16 and Felix-O1a (FO1a) was applied during tumbling at 10(7) and 10(8)PFU/ml. Samples were held at 4°C for 6h and 18h (red meat) and 30min and 6h (poultry). Overall, bacteriophage application on trim reduced 1 and 0...

Shakuntla Verma, Munish Ahuja
In the present study, carboxymethyl Sesbania gum was synthesized and evaluated for drug delivery. Carboxymethylation was carried out by reacting with monochloroacetic acid under alkaline conditions. Modification of the gum was confirmed by Fourier-transform infrared spectroscopy. The degree of carboxymethyl substitution was determined to be 1.3. Carboxymethylation improved the flow properties, increased the degree of crystallinity and changed the compression behaviour from elastic to plastic. Further, the interaction between the modified gum and Ca(2+)-ions was optimized employing a 3-factor, 3-level central composite experimental design to prepare mucoadhesive sustained release beads using metformin hydrochloride as the model drug...

To modulate T cell function for cancer therapy one challenge is to selectively attenuate regulatory but not conventional CD4+ T cell subsets (Treg and Tconv). In this study we show how a functional dichotomy in Class IA PI3K isoforms in these two subsets of CD4+ T cells be exploited to target Treg while leaving Tconv intact. Studies employing isoform-specific PI3K inhibitors and a PI3Kδ-deficient mouse strain revealed that PI3Kα and PI3Kβ were functionally redundant with PI3Kδ in Tconv. Conversely, PI3Kδ was functionally critical in Treg, acting there to control TCR signaling, cell proliferation and survival...

Xanthomonas translucens pv. undulosa (Xtu) causes Bacterial Leaf Streak disease in the staple food crops such as wheat and barley. The survival strategies of pathogen and host are determined by the complex interactions occurring between the host plants and the pathogenic microbes. Iron binding proteins are important in the plant-microbe interactions as they are indulged in enzyme catalysis, virulence, metabolic and transport activities. In the presented study, we have identified that ~9.8% of Xtu proteome possess iron binding sequence motifs...

A 57-year-old female presenting with acute-onset paraplegia was referred for magnetic resonance imaging (MRI) of cervico-dorsal spine. On MRI, multiple tortuous dilated vessels were noted in the epidural space with long segment cord compression and imaging features of compressive myelopathy. Associated small acute cervico-dorsal epidural hematoma was also noted in the same region. Computed tomography (CT) angiography was performed subsequently which revealed post-ductal coarctation of aorta with multiple arterial collaterals in the chest wall and spinal canal...

Energies and relative Intensities of 13 X-ray transitions in the M X-ray spectrum (per 100 disintegrations of (241)Am) viz. M4N1, Mξ1,2, M3N1, Mα, Mβ, Mγ, M2N1, M3O4,5+M3P1, M3Q1, M1N3, M2N4+M1N3, M2O1 and M1O2,3 lines along with L1-L3 have been measured in addition to the 21L X-ray lines viz. Lℓ, Lt, Ls, Lα2, Lα1, Lη, Lβ6, Lβ2,15, Lβ4, Lβ5,7, Lβ1, Lβ3, Lβ9,10, Lγ5, Lγ1, Lγ2,8, Lγ3,6, Lγ4,4, Lγ13 including two new lines at 19.63 and 23.17keV, have been measured. Since the M and L X-ray lines of 93Np in the decay of (241)Am source are frequently used for energy and efficiency calibration of the Si(Li)/HpGe detectors, the present measurements have been undertaken with an objective to update the data since there are either no concrete data available (even in the Table of Radioactive Isotopes and Table of Radionuclides) or there exist inconsistencies/disparities in the data available in the earlier publications...

Patient reported outcomes (PROs) serve an integral role in clinical research by helping to determine the impact of clinical care as experienced by the patient. With recent initiatives in health care policy and pay for performance, outcome reporting is now recognized as a policy-driven requirement in addition to a clinical research tool. For outcome measures to satisfy these regulatory requirements and provide value in understanding disease outcomes, they must be responsive and efficient. Recent research has uncovered certain concerns regarding traditional PROs in patients with upper extremity disability and injury...

The IgA receptor, Fcar (CD89) consists of five sequence segments: two segments (S1, S2) forming the potential signal peptide, two extracellular EC domains that include the IgA binding site, and the transmembrane and cytoplasmic tail (TM/C) region. Numerous Fcar splice variants have been reported with various combinations of the sequence segments mentioned above. Here, we report a novel splice variant termed variant APD isolated from a healthy volunteer that lacks only the IgA-binding EC1 domain. Despite possessing the complete signal peptide S1+S2, the variant APD is only found in the intracellular space whereas the wild-type variant 1 is efficiently secreted and variant 4 leaks to the extracellular space...

Naphthoquinones are naturally occurring biologically active entities. Practical de novo syntheses of three naphthoquinones i.e. lawsone (1), lapachol (2), and β-lapachone (3b) have been achieved from commercially available starting materials. The conversion of lapachol (2) to β-lapachone (3b) was achieved through p-TSA/Iodine/BF3-etherate mediated regioselective cyclisation. Further, 2-alkyl and 2-benzyllawsone derivatives have been prepared as possible anticancer agents. Four derivatives exhibited significant anticancer activity and the best analogue i...
