Introduction Non-Hodgkin Lymphoma (NHL) is a heterogeneous lymphoproliferative malignancy with B cell origin. Combinatorial treatment of rituximab, cyclophsphamide, hydroxydaunorubicin, oncovin, prednisone (R-CHOP) the standard regimen for NHL, yielding complete remission (CR) rate 40-50%. Unfortunately, considerable patients undergo relapse after CR or initial treatment, resulting in poor clinical implications. Patient’s response to chemotherapy varies widely from static disease cancer...
Abstract Heterogeneity within the tumor-infiltrating lymphocytes (TIL) population limits immunotherapeutic efficacy against cancer. Between two subpopulations of exhausted CD8+ TILs (progenitor-exhausted; TPEX, terminally exhausted; TTEX), TTEX cells remain unresponsive to anti–programmed cell death protein 1(PD-1) therapy. Deciphering whether and how PD-1–resistant engage in tumor promotion could improve response immunotherapy. Here, we report that actively participate progression by...
Radioactive gold-198 nanoparticles have been synthesized using a green and chemically safe solvent, PEG 4000. In the present investigation, 198Au(III) has quantitatively extracted by PEG-rich phase without addition of any other extractant. Extraction is quantitative even at very high gold concentration (50 mM) after extraction Au(III) reduced to Au(0) forming radioactive nanoparticles. The containing characterized UV-visible spectroscopy actual size determined transmission electron microscopy (TEM).
Glutamine synthetase (GS) is one of the most important metabolic enzymes which catalyzes ligation glutamate and ammonia to form glutamine. Previous studies from our lab had revealed significant differences in parasite host GS enzyme warranted us further work on its relevance parasite. To analyze glutamine function Leishmania , we generated overexpressors knockout mutants evaluated their ability grow vitro monocyte differentiated macrophage vivo by infections BALB/c mice. knocked out strain...
A six-dimensional integral in the coordinate space of two particles 1 and 2, where integrand contains Coulomb functions for both particles, term $\frac{1}{|{\stackrel{\ensuremath{\rightarrow}}{\mathrm{r}}}_{1}\ensuremath{-}{\stackrel{\ensuremath{\rightarrow}}{\mathrm{r}}}_{2}|}$, an exponential term, is reduced to a double real space. The resulting can finally be integrated numerically with high degree accuracy. This technique has been verified by its application Nordsieck bremsstrahlung...
Abstract Repurposing drugs and adjuvants is an attractive choice of present therapy that reduces the substantial costs, chances failure, systemic toxicity. Mycobacterium indicus pranii was originally developed as a leprosy vaccine but later has been found effective against Leishmania donovani infection. To extend our earlier study, here we reported immunotherapeutic modulation splenic circulatory neutrophils in favour hosts actually serve pro‐parasitic portable shelter to infection...
Synthesis of gold-palladium bimetallic nanoparticles using in situ radioactivity from (198)Au isotope is reported this paper. Gold solution spiked with (198)Au(III) has been mixed PdCl2 measured proportions 50% polyethylene glycol solution. Au(III) and Pd(II) are reduced, formed due to radiolysis the polymer The characterized by UV-visible spectra, actual size determined transmission electron microscopy conjugation energy dispersive X-ray measurements.
The cross sections of single and double electron capture for an alpha particle passing through a helium atom have been calculated incident ion energies ranging from 50 to 1500 keV, using the impact parameter method. momentum transfer exchange electrons taken into account. 2s 2p excitations ionized in both direct captured states by perturbation results obtained are compared with available experimental other theoretical findings. present found be fairly good agreement findings up energy about...
The speciation study of Cr(III) and Cr(VI) was carried out using a polyethylene glycol (PEG) based aqueous biphasic extraction system (ABS). Neutron activated salts were assayed in HPGe detector before after employing extraction. Different various salting abilities taken as the salt rich phase. best condition for maximum differential attitude ABS to observed when 2 M Na SO 4 PEG #4000 (50% w/w) solutions used. can also be extracted by with prior complexation diphenylthiocarbazone...
A survey of rural and urban student populations was undertaken to determine the prevalence dermatomycoses in district Puri (Orissa). Tinea corporis found be predominant disease area whereas t. cruris dominant area. T. capitis absent both areas. Except for M. gypseum no other dermatophyte isolated from soil. rubrum (87·5%) most commonly fungus. Among geophilic fungi soil, species Chrysosporium were common.

A final-state wavefunction, involving three appropriate confluent hypergeometric functions, which satisfies the correct asymptotic condition is used to study positron-impact ionization of atomic hydrogen. Results are reported for double as well triple differential cross sections and compared with available theoretical findings. The section curves different ejection angles show presence a cusp-like structure at region equal energy sharing by outgoing positron ejected electron. This in...
A method has been suggested for the numerical integration of electron-hydrogen ionisation amplitudes in Born approximation, where two outgoing electrons are described as product Coulomb waves. Different sets effective charges scattered and ejected have considered. The expression amplitude reduced to a one-dimensional integral real space results compared with other theoretical experimental findings.
A polyethylene glycol based aqueous biphasic system has been studied for the extraction and separation of long-lived radionuclides, 152,154Eu 134Cs. The effects pH variation salt rich phases on properties these radionuclides were experimental results found to be supported by theoretical calculations. It observed that at neutral sodium sulphite 11 phosphate phase 134Cs could separated from radionuclides. exact forming concentrations determined measuring volume after equilibration.
