Use of different cellulosic wastes for production of Oyster mushroom. (2010)

Two local and five exotic strains of Oyster mushrooms were investigated on three cellulosic wastes incuding, cotton waste, paddy straw and corn stover to evaluate the spawn running and yield performance. Among different strains, Pleurotus (florida) ostreatus WC-536(exotic) and local strain Pleurotus florida P-17 were found to be the best strains in completion of 100% spawn running in a very short period of time. Maximum yield was obtained on cotton waste substrate followed by corn stover and paddy straw substrate.
Augmented Reality Videoconferencing for Collaborative Work (2003)

This paper describes an Augmented Reality videoconference system, which is a novel remote collaboration tool combining a desktop-based AR system and a videoconference module. The novelty of our system is the combination of these tools with AR applications superimposed on live video background displaying the conference parties ’ real environment, merging the advantages of the natural face-to-face communication of videoconferencing and AR’s interaction capabilities with distributed virtual objects using tangible physical artifacts. The simplicity of the system makes it affordable for everyday use. We explain our system design based on concurrent video streaming, optical tracking and 3D application sharing, and provide experimental proof that it yields superior quality compared to pure video streaming with successive optical tracking from the compressed streams. Collaborative AR applications built on our framework are presented, which are followed by the outcomes of an initial user study taking ergonomic and usability aspects into account. 1.
A Possible Cannizzaro's Reaction of Berberine In Vivo (1961)

Three alkaloids berberine, lambertine and berlambine occur simultaneously in Berberis lambertii Parker. This work deals with establishing that lambertine and berlambine are not artifacts during isolation. The author suggests that berberine has undergone Cannizzaro's reaction to produce the other two alkaloids, a reaction so far known in vitro taking place also in vivo .
Coupling of <i>Tetrahymena</i> Ribosomal RNA Splicing to β-Galactosidase Expression in <i>Escherichia coli</i> (1985)

Splicing of the Tetrahymena ribosomal RNA precursor is mediated by the folded structure of the RNA molecule and therefore occurs in the absence of any protein in vitro. The Tetrahymena intervening sequence (IVS) has been inserted into the gene for the alpha-donor fragment of beta-galactosidase in a recombinant plasmid. Production of functional beta-galactosidase is dependent on RNA splicing in vivo in Escherichia coli. Thus RNA self-splicing can occur at a rate sufficient to support gene expression in a prokaryote, despite the likely presence of ribosomes on the nascent RNA. The beta-galactosidase messenger RNA splicing system provides a useful method for screening for splicing-defective mutations, several of which have been characterized.
Multiple receptors for brain dopamine. (1978)

This study was done to obtain direct in vitro evidence for the possible existence of more than one type of dopaminergic binding site in homogenates of the caudate nucleus from calf brain. Five radioligands for dopaminergic sites were tested. The inhibitions of two agonist radioligands ([3H]dopamine, [3H]apomorphine) by haloperidol, chlorpromazine, or piflutixol were biphasic. The inhibitions of [3H]haloperidol, [3H]spiroperidol, and [3H]dihydroergocryptine binding by dopamine and (-)-norepinephrine were also biphasic. Thus, both 3H-labeled agonists and 3H-labeled antagonists were possibly binding to two high-affinity sites.
Therapy of prostatic cancer and histopathologic follow‐up (1982)

The histopathologic follow-up of local tumor regression of prostatic cancer under hormonal treatment or following high-voltage therapy is an objective standard to determine a therapeutic success. This report involves 308 patients, who were continuously controlled by serial biopsies, 1,138 punch biopsies, and 155 TURs from 1971 to 1981. On an average, there are 4.2 biopsies of each patient. The patients were treated with estradiol. They were divided into two groups by histologic classification: 1) adenocarcinomas with large and small acinar pattern (130 cases) and 2) carcinomas with cribriform and/or solid pattern, partly mixed with other glandular types (178 cases). We applied a score of 10 points to divide the histopathologic regression into three gradings: pronounced, moderate, and poor or no regression. In adenocarcinomas a pronounced regression can be seen in 67.8% following three or more years of hormonal treatment, and in 64.7% following primary high-voltage therapy, mostly combined with hormonal treatment or orchiectomy. In adenocarcinomas with poor or no regression a percentage of 20.4 or 14.7, respectively, can be seen. In cribriform and solid carcinomas a significant difference is present between hormonal treatment and radiotherapy. Following hormonal treatment only 20.2%, but following radiotherapy 63.6% show a pronounced regression. Accordingly, 48.8% of these carcinomas show no or only poor regression under hormonal treatment after three or more years of follow-up. Following radiotherapy, there are only 21.3%. The conformity of locally palpable finding and histopathologic grading of regression reaches 70%. If no agreement can be achieved, cases with better palpable finding than histopathologically recognizable regression prevail.
Detection of rounded opacities on chest radiographs using convergence index filter (2003)

This paper presents a method to detect rounded opacities on digital chest radiographs. Based on a model of rounded opacities, three filters that evaluate the convergence degree of gradient vectors in the neighborhood of the pixel of interest are investigated to detect rounded opacities in the complex lung area. These filters do not depend on the contrast of the rounded opacity to its background. Their outputs depend on only the distribution of the gradient vector orientation. Experiments to test their performance have been performed. Their results show the effectiveness of the proposed filters. Especially, the iris filter and the adaptive ring filter are shown to be very effective in detecting cancerous tumor candidates. Another experiment to compare the performance of the iris filter and the Min-/spl Phi/DD filter which is one of the filters effective in detecting rounded opacities have been performed and the superiority of the proposed filters has been shown.
Transformation of <i>Arabidopsis thaliana</i> with <i>Agrobacterium tumefaciens</i> (1986)

Transformed Arabidopsis thaliana plants have been produced by a modified leaf disk transformation-regeneration method. Leaf pieces from sterilely grown plants were precultured for 2 days and inoculated with an Agrobacterium tumefaciens strain containing an avirulent Ti (tumor-inducing) plasmid with a chimeric gene encoding hygromycin resistance. After cocultivation for 2 days, the leaf pieces were placed on a medium that selects for hygromycin resistance. Shoots regenerated within 3 months and were excised, rooted, and transferred to soil. Transformation was confirmed by opine production, hygromycin resistance, and DNA blot hybridization of both primary transformants and progeny. This process for producing transgenic Arabidopsis plants should enhance the usefulness of the species for experimental biology.
A Role of the –35 Element in the Initiation of Transcription at psbA Promoter in Tobacco Plastids (2003)

Most plastid promoters recognized by bacteria-like plastid RNA polymerase (PEP) are similar to E. coli sigma(70)-type promoters comprising "-35" and "-10" elements. Among them, psbA promoter is unique in bearing additional elements between the conserved -35 and -10 elements. The psbA promoter activity is differentially maintained in the mature chloroplasts where the activity of most PEP promoters declines. Previously, we identified two types of PEP activities in wheat seedlings [Satoh et al. (1999) Plant J. 18: 407]; PEP present in the mature chloroplasts of the leaf tip (tip-type PEP) can initiate transcription from the -35-destructed psbA promoter, but the -35 element is essential for transcription by PEP present in immature chloroplasts of the leaf base (base-type PEP). To reveal which type of PEP functions in various types of plastids in tobacco, we analyzed the tobacco psbA promoter by means of a transplastomic approach. The promoter core context (-42 to +9) was sufficient for developmental regulation of the psbA promoter activity. The -35 promoter element was important for transcription initiation at the psbA promoter in all types of plastids, including chloroplasts in mature leaves, leucoplasts in roots, etioplasts in etiolated cotyledons. The conclusion is that the PEP bearing a promoter preference, similar to the wheat base-type PEP, functions dominantly in tobacco chloroplasts.
Identification of the Receptor-Binding Protein in 936-Species Lactococcal Bacteriophages (2004)

The aim of this work was to identify genes responsible for host recognition in the lactococcal phages sk1 and bIL170 belonging to species 936. These phages have a high level of DNA identity but different host ranges. Bioinformatic analysis indicated that homologous genes, orf18 in sk1 and orf20 in bIL170, could be the receptor-binding protein (RBP) genes, since the resulting proteins were unrelated in the C-terminal part and showed homology to different groups of proteins hypothetically involved in host recognition. Consequently, chimeric bIL170 phages carrying orf18 from sk1 were generated. The recombinant phages were able to form plaques on the sk1 host Lactococcus lactis MG1614, and recombination was verified by PCR analysis directly with the plaques. A polyclonal antiserum raised against the C-terminal part of phage sk1 ORF18 was used in immunogold electron microscopy to demonstrate that ORF18 is located at the tip of the tail. Sequence analysis of corresponding proteins from other lactococcal phages belonging to species 936 showed that the N-terminal parts of the RBPs were very similar, while the C-terminal parts varied, suggesting that the C-terminal part plays a role in receptor binding. The phages investigated could be grouped into sk1-like phages (p2, fd13, jj50, and phi 7) and bIL170-like phages (P008, P113G, P272, and bIL66) on the basis of the homology of their RBPs to the C-terminal part of ORF18 in sk1 and ORF20 in bIL170, respectively. Interestingly, sk1-like phages bind to and infect a defined group of L. lactis subsp. cremoris strains, while bIL170-like phages bind to and infect a defined group of L. lactis subsp. lactis strains.

A More Multifactor Secure Authentication Scheme Based on Graphical Authentication (2012)

The Current authentication systems suffer from many drawbacks we generally use knowledge based technique e.g textual passwords. In this users choose a string (combination of letters numbers etc) from their known facts like birth day mobile number etc, which make textual passwords easy to break and vulnerable to dictionary based or brute force attacks because of the knowledge of some of the traits to other persons too, moreover the malicious person can also guess the password. Secondly, Inherence authentication like biometric requires hardware. Thirdly, ownership based authentication like cards etc also require hardware etc .Now Graphical Authentication mechanisms have been proposed but they are found vulnerable to shoulder surfing attacks. In this paper we propose a combined approach of graphic, knowledge based technique and also biometric form to make authentication system computationally secure.
Marketing approval of mogamulizumab (2012)

Therapeutic properties of antibodies strongly depend on the composition of their glycans. Most of the currently approved antibodies are produced in mammalian cell lines, which yield mixtures of different glycoforms that are close to those of humans, but not fully identical. Glyco-engineering is being developed as a method to control the composition of carbohydrates and to enhance the pharmacological properties of mAbs. The recent approval in Japan of mogamulizumab (POTELIGEO (®) ), the first glyco-engineered antibody to reach the market, is a landmark in the field of therapeutic antibodies. Mogamulizumab is a humanized mAb derived from Kyowa Hakko Kirin's POTELLIGENT (®) technology, which produces antibodies with enhanced antibody-dependent cell-mediated cytotoxicity (ADCC) activity. The approval was granted April 30, 2012 by the Japanese Ministry of Health, Labour and Welfare for patients with relapsed or refractory CCR4-positive adult T-cell leukemia-lymphoma.
Phonon-Assisted Electroluminescence from Metallic Carbon Nanotubes and Graphene (2010)

We report on light emission from biased metallic single-wall carbon nanotube (SWNT), multiwall carbon nanotube (MWNT) and few-layer graphene (FLG) devices. SWNT devices were assembled from tubes with different diameters in the range 0.7-1.5 nm. They emit light in the visible spectrum with peaks at 1.4 and 1.8 eV. Similar peaks are observed for MWNT and FLG devices. We propose that this light emission is due to phonon-assisted radiative decay from populated pi* band states at the M point to the Fermi level at the K point. Since for most carbon nanotubes as well as for graphene the energy of unoccupied states at the M point is close to 1.6 eV, the observation of two emission peaks at approximately 1.6 +/- approximately 0.2 eV could indicate radiative decay under emission or absorption of optical phonons, respectively.
Inhibition of Autophagy by Deguelin Sensitizes Pancreatic Cancer Cells to Doxorubicin (2016)

Pancreatic cancer is the fourth most common cause of cancer mortality worldwide. Furthermore, patients with pancreatic cancer experience limited benefit from current chemotherapeutic approaches because of drug resistance. Therefore, an effective therapeutic strategy for patients with pancreatic cancer is urgently required. Deguelin is a natural chemopreventive drug that exerts potent antiproliferative activity in solid tumors by inducing cell death. However, the molecular mechanisms underlying this activity have not been fully elucidated. Here we show that deguelin blocks autophagy and induces apoptosis in pancreatic cancer cells in vitro. Autophagy induced by doxorubicin plays a protective role in pancreatic cancer cells, and suppressing autophagy by chloroquine or silencing autophagy protein 5 enhanced doxorubicin-induced cell death. Similarly, inhibition of autophagy by deguelin also chemosensitized pancreatic cancer cell lines to doxorubicin. These findings suggest that deguelin has potent anticancer effects against pancreatic cancer and potentiates the anti-cancer effects of doxorubicin. These findings provide evidence that combined treatment with deguelin and doxorubicin represents an effective strategy for treating pancreatic cancer.
Genetic Variation among Temporally and Geographically Distinct West Nile Virus Isolates, United States, 2001, 2002 (2003)

Analysis of partial nucleotide sequences of 22 West Nile virus (WNV) isolates collected during the summer and fall of 2001 and 2002 indicated genetic variation among strains circulating in geographically distinct regions of the United States and continued divergence from isolates collected in the northeastern United States during 1999 and 2000. Sequence analysis of a 2,004-nucleotide region showed that 14 isolates shared two nucleotide mutations and one amino acid substitution when they were compared with the prototype WN-NY99 strain, with 10 of these isolates sharing an additional nucleotide mutation. In comparison, isolates collected from coastal regions of southeast Texas shared the following differences from WN-NY99: five nucleotide mutations and one amino acid substitution. The maximum nucleotide divergence of the 22 isolates from WN-NY99 was 0.35% (mean = 0.18%). These results show the geographic clustering of genetically similar WNV isolates and the possible emergence of a dominant variant circulating across much of the United States during 2002.
QRP: An improved secure authentication method using QR codes (2012)

It seems quite obvious that any online service that aims to be secure nowadays should seriously consider implementing a strong authentication method. This paper presents the design and implementation of QRP, an open source, proof-of-concept authentication system that uses a two-factor authentication by combining a password and a camera-equipped mobile phone, acting as an authentication token. QRP is extremely secure as all the sensitive information stored and transmitted is encrypted, but it is also an easy to use and cost-efficient solution. QRP is portable and can be used securely in untrusted computers. Finally, QRP is able to successfully authenticate even when the phone is offline.

Proton exchange rates from amino acid side chains— implications for image contrast (1996)

The proton exchange rates between water and the hydroxyl protons of threonine, serine, tyrosine, the amino protons of lysine, and the guanidinium protons of arginine were measured in the pH range 0.5 to 8.5 and for the temperatures 4 degrees C, 10 degrees C, 20 degrees C, 30 degrees C, and 36 degrees C. The intrinsic exchange rates of the hydroxyl and amino protons at pH 7.0 degrees C and 36 degrees C were found to be in the range 700 to about 10,000 s-1. In addition, the exchange catalysis by phosphate, carbonate, carboxyl-, and amino-groups was investigated. The presence of these exchange catalysts at physiological concentrations increased the proton exchange rates from hydroxyl and amino groups several fold. The proton exchange rates are sufficiently fast that the total magnetization transfer between biomolecules and free bulk water is not rate limited by the proton exchange rate, but by the intramolecular cross-relaxation rates between the exchangeable and nonexchangeable protons of the biomolecules. Since the cross-relaxation rates between surface hydration water molecules and biomolecules are usually vanishingly small because of too rapid exchange with the free bulk water, it is proposed that the contrast in MR images is a fingerprint of the number of the exchangeable protons from OH and NH groups of the tissue, as far as the contrast depends on the magnetization transfer between biomolecules and water.

Homogenization of some variational inequalities for some elasto-plastic problems (2004)

Methods of homogenization for variational inequalities with gradient constraints are presented. The variational inequalities are defined by a monotone operator of second order with periodic rapidly oscillating coefficients. The macroscopic homogenized (limiting) variational inequality satisfied by the limit of the solutions of the variational inequalities is deduced. Methods of variational inequalities theory and the notion of two-scale convergence are used for passage to the limit. The relevant feature of the homogenized variational inequality is its twice-nonlinear form, which is different from that of the initial variational inequality. A comparison with the homogenization for constrained minimization problems is given
Mechanisms and controllers of eccrine sweating in humans (2009)

Human body temperature is regulated within a very narrow range. When exposed to hyperthermic conditions, via environmental factors and/or increased metabolism, heat dissipation becomes vital for survival. In humans, the primary mechanism of heat dissipation, particularly when ambient temperature is higher than skin temperature, is evaporative heat loss secondary to sweat secretion from eccrine glands. While the primary controller of sweating is the integration between internal and skin temperatures, a number of non-thermal factors modulate the sweating response. In addition to summarizing the current understanding of the neural pathways from the brain to the sweat gland, as well as responses at the sweat gland, this review will highlight findings pertaining to studies of proposed non-thermal modifiers of sweating, namely, exercise, baroreceptor loading state, and body fluid status. Information from these studies not only provides important insight pertaining to the basic mechanisms of sweating, but also perhaps could be useful towards a greater understanding of potential mechanisms and consequences of disease states as well as aging in altering sweating responses and thus temperature regulation.
