Abstract
BACKGROUND The pathogenesis of gastro-oesophageal reflux disease includes increased acid reflux, reduced salivation and impaired peristalsis. This may depend upon the height of acid wave and magnitude of oesophageal mucosal exposure. Interestingly, the effect of site of acid infusion upon salivary secretion and heartburn has not been examined in any detail. AIM To examine whether acid infusion in the upper oesophagus may cause increased salivation and heartburn as compared with acid infusion in the lower oesophagus. METHODS Twelve healthy male subjects (mean age 30) received infusions of HCl, citric acid and acetic acid at 10 and 20 cm above the lower oesophageal sphincter (LES) for fixed time periods. Parotid saliva collected periodically and heartburn severity scored using standardized scale. Standard statistical methods (paired t-tests, analysis of variance) were used to determine the significance of results. RESULTS Acid infusion in the upper oesophagus increased parotid flow rate as compared with that in the lower oesophagus (P < 0.05). Likewise, there was a significantly increased heartburn score at 20 cm as well as 10 cm above LES (P < 0.05) as compared with that in the stomach. CONCLUSION These data suggest a significant increase in salivation and heartburn in response to acid infusion in the upper vs. lower part of the oesophagus.

Abstract
During microbial or mammalian cell metabolism, TNT (2,4,6-tinitrotoluene) is reduced to 2Am-DNT (2-amino-4,6-dinitrotoluene), 4Am-DNT, or 2,4-diamino-NT (2,4-diaminonitrotoluelne) depending on the specific organism. The metabolite 2Am-DNT is the most common of the TBT biotransformation pathways in bacterial and fungal species studied to date. in the mammalian liver cells, TNT is metabolized to 2Am-DNT by the P450 enzyme system. Apoptosis is rapidly emerging as a relevant endpoint for detecting low-dose toxin exposure. We report in this study that 2Am-DNT treatment of mammalian cells causes cell death by apoptosis. Cell death was assayed by the Trypan Blue method. Apoptotic changes, such as DNA break down, were detected in treated cells by the production of a dark-brown DAB (diaminobenzidine) signal using the Fragel Klenow DNA fragment detection system, by immunohistochemical techniques with fluorescence microscopy, and by using a microplate reader for a single-stranded DNA binding assay. All of these results showed that 2am-DNT is toxic to mammalian cells and induces apoptosis.

Abstract
The dechlorination of PCB, specifically the noncoplanar congener PCB 153, has been observed in the presence of a crude nitrate reductase extract from Medicago sativa leaves. These observations were further confirmed using a commercially available and pure nitrate reductase from Zea mays. The presence of nitrate reductase increased PCB 153 dechlorination. Then, the addition of molybdenum, the enzyme's cofactor, enhanced dechlorination of the environmental contaminant. The ability of plant nitrate reductase to dechlorinate PCB is a new observation.

Abstract
GIPC is highly expressed in human pancreatic adenocarcinoma and is a central protein for the stability of IGF-1R in pancreatic adenocarcinoma cell lines (15). The goal of this study was to prove the importance of GIPC in vivo and to evaluate possible therapeutic strategies that target this protein and its PDZ domain. In vivo effects of GIPC knockout were studied after lentiviral transduction of luciferase-expressing MiaPaCa2 pancreatic cancer cells with shRNA against GIPC; growth characteristics were monitored with bioluminiscence. Knockdown of GIPC led to a significant inhibition of pancreatic tumor cell growth in vivo in different mouse models. To test a possible therapeutic approach, the PDZ domain of GIPC was targeted by a short peptide composed of the amino acid sequence PSQSSSEA. This octapeptide was designed based on the C-terminal binding motif of GAIP. Targeting GIPC with this peptide inhibited the association between IGF-1R and GIPC. The subsequent downregulation of IGF-1R decreased proliferation in vitro and in vivo. In conclusion, our findings suggest that targeting GIPC and its PDZ domain-mediated interaction with the tyrosine kinase receptor IGF-1R could be a promising new treatment option for pancreatic cancer.

Abstract
Polychlorinated biphenyls (PCBs) are among the most widespread and persistent pollutants in the global environment. Coplanar and noncoplanar PCBs have been shown to cause congener-specific apoptosis mediated neurotoxicity in rats. Very few, if any, such studies have been reported on human renal cell toxicity. The authors report here caspase-dependent or caspase-independent renal toxicity, as measured by apoptotic death induced by PCBs, depending on the planarity of congeners PCB-77 (coplanar) and PCB-153 (noncoplanar) in human kidney cells (HK2) in vitro. The authors have combined morphological and biological techniques to discover the relevance of apoptosis in renal proximal tubule cell death induced by these two PCB congeners. Treatment with both PCB congeners caused accelerated apoptosis in a time- and concentration-dependent manner. Based on our findings using human kidney (HK2) cells, there was more apoptosis-mediated loss of cell viability by non-ortho-substituted PCB-77 when compared to PCB-153. A significant increase of caspase-3 expression through immunoblot studies showed the involvement of apoptosis by PCB-77 compared to none by PCB-153. The broad-spectrum caspase inhibitor z-VAD-fmk showed increased cell death when treated by PCB-153, but not by PCB-77, confirming that caspase inhibitor induced a switch in the mode of cell death. It is reasonable to assume that apoptotic cell death in the renal proximal tubule cells treated by PCBs may have both caspase-dependent and caspase-independent pathways.

Abstract
The study was designed to examine the binding of diclofenac sodium with bovine serum albumin (BSA) at different temperatures (20 degrees, 30 degrees and 40 degrees C), pH (6.4, 7.4 and 8.4) and ionic strengths (micro = 0.1, 0.2 and 0.3) by means of equilibrium dialysis method. The concentration of diclofenac sodium was maintained at wider range from 15 to 900 micromole/l and BSA concentration was maintained at 61.5 micromole/l. The data obtained were interpreted by nonlinear regression method using Graphpad prism software. The analysis showed that the interaction between diclofenac sodium with BSA results in two-site saturable binding. A decrease in association constant was observed with increasing temperature. The average standard free energy change (deltaGdegrees) value was -7.07 (site I) and -4.2 (site II) Kcal/mol. The standard enthalpy change (deltaHdegrees) and the standard entropy change (deltaSdegrees) were -7.8 Kcal/mole, -2.35 cal/mole (site I) and -7.4 Kcal/mole, -10.5 cal/mole (site II), respectively. The negative enthalpy change suggested the binding between diclofenac sodium and the binding sites of BSA were spontaneous and exothermic. The negative value of deltaHdegrees and deltaSdegrees indicated hydrogen bonding and van der Waal's force was the major mechanism for diclofenac sodium and BSA interaction. Increase in pH and ionic strength also caused decrease in association constant of diclofenac sodium and BSA binding.

Abstract
The genome of the nitrogen-fixing soil bacterium Sinorhizobium meliloti does not possess genes for bioremediation of aromatic pollutants. It has the well-known ability to interact specifically with the leguminous alfalfa plant, Medicago sativa. Our previous work has shown enhanced degradation of the nitroaromatic compound 2,4-dinitrotoluene (DNT) when a plasmid containing degradative genes was introduced in it. In this study we report molecular evidence of the transfer of a polychlorinated biphenyl (PCB)-biodegradative plasmid pE43 to S. meliloti strain USDA 1936. Several standard analytical tests and plant growth chamber studies were conducted to test the ability of S. meliloti to degrade 2',3,4-PCB congener. Alfalfa plant alone was able to degrade 30% of PCBs compared with control. No enhanced dechlorination was noted when alfalfa plant was grown with wild-type S. meliloti, and when alfalfa plant was grown with the S. meliloti electrotransformants (genetically modified) dechlorination of PCBs was more than twice that when alfalfa plant was grown with wild-type S. meliloti. When alfalfa plant was grown with uncharacterized mixed culture (containing nodule formers), almost equally significant PCB degradation was observed. The significance of this work is that the naturally occurring nitrogen-fixing soil bacterium S. meliloti (genetically modified) has the ability to enhance fertility of soil in association with the leguminous alfalfa plant while simultaneously enhancing bioremediation of PCB-contaminated soils. Enhanced bioremediation of PCB and robust alfalfa plant growth was also noted when uncharacterized mixed cultures containing alfalfa plant nodule formers were used.

Abstract
Representative species from the monoflagellate Blastocladiales and the biflagellate Saprolegniales were studied for their DNA base composition, heterogeneity, nucleotide sequence homology and divergence. Intergeneric, intrageneric and interstrain DNAs of Blastocladiales were heterogenous. The G+C values for their main component (average 64 percent) and two minor ones (average 52 and 44 percent) were found to be significantly higher than the corresponding values from the biflagellate Saprolegnia ferax (55, 46 and 36 percent respectively). In Allomyces species, the two hybrid, male and female strains were found to have closer homology with their parental types than these last between themselves. Among Blastocladiales, interspecific similarities between the epigynous A. macrogynus and the hypogynous A. arbuscula were higher (average 75 percent) than intergeneric similarities between Allomyces and Blastocladiella (average 58 percent). The biflagellate S. ferax was found to be distantly related to the uniflagellate Allomyces (average 48 percent similarity). The nucleotide sequence divergences obtained from thermal elution data correlated the hybridization values.

Abstract
We study the quantum mechanical behavior of a macroscopic, three-body, superconducting circuit. Microwave spectroscopy on our system, a resonator coupling two large Josephson junctions, produced complex energy spectra well explained by quantum theory over a large frequency range. By tuning each junction separately into resonance with the resonator, we first observe strong coupling between each junction and the resonator. Bringing both junctions together into resonance with the resonator, we find spectroscopic evidence for entanglement between all 3 degrees of freedom and suggest a new method for controllable coupling of distant qubits, a key step toward quantum computation.

Abstract
Prolonged exposure to arsenic contaminated water produces various clinical features, cutaneous features e.g. melanosis, keratosis and cancers being very common. Evaluation of such lesions by proliferative markers can provide useful information in regards to the biological behaviour of the lesions. Thus, cases with high proliferative status can be ominous sign for development of cancers. We studied skin biopsy of 42 cases. These were evaluated with AgNOR score and PCNA stain, in addition to H & E examination. Here, invasive cancer cases had mean AgNOR score of 3.56, those with severe dysplasia had 3.0, moderate and mild dysplasia scored 1.73, benign changes had mean score of 1.35 while normal control cases had 1.08. PCNA index in cancers was above 50, that of severe dysplasia 25-30, mild to moderate dysplasia 1.0-5.0, those with benign changes 0.5 -1.0 and normal control had LI of less than 0.5%. PCNA has the advantage of less chance of observer error over AgNOR stain.

Abstract
With a view to determine ectopic limb developing capacity along with normal hind limb regeneration in response to vitamin A palmitate in well-differentiated hind limb stage tadpoles of P. maculatus, higher doses of vitamin A (30 IU/ml and 20 IU/ml) were administered for a longer period (120 hr) to the tadpoles following tail amputation through middle and hind limb amputation through middle of thigh. Simultaneous development of ectopic pelvic zone was observed along with hind limbs from the cut end of tail and duplication of regenerated hind limbs in the same tadpole for the first time. Besides, development of double ectopic pelvic girdle was also reported in one case. Results also indicate that induction of pelvic zone and duplication of regenerated limbs are concentration dependent.

Abstract
With in-stent restenosis remaining major limitation of coronary stenting and adjunctive pharmacologic therapy and re-stenting having failed to reduce the rates of in-stent restenosis, a new treatment alternative is warranted. Vascular brachytherapy - the intracoronary delivery of radiation has been proposed as one such therapy. Thus far it is an important break-through in combating re-stenosis. Todate, 5 years of clinical data has been generated and further studies are underway to perfect the technology.

The dependence of the electric field on the time delay between the ion plasma production and the probe of the electric field reflects the Coulomb expansion of the plasma. Our experiments and models show expansion times <1micros.

Abstract
We demonstrate a real-time feedback scheme to manipulate wave-packet oscillations of atoms in an optical lattice. The average position of the atoms in the lattice wells is measured continuously and nondestructively. A feedback loop processes the position signal and translates the lattice potential. Depending on the feedback loop characteristics, we find amplification, damping, or an entire alteration of the wave-packet oscillations. Our results are well supported by simulations.

Abstract
In order to establish the mechanism(s) of immunomodulatory and anti-tumor properties of sheep erythrocytes (SRBC), the T11 target structure (T11TS) or CD58 molecule as a pertinent component of SRBC was isolated, purified and finally administered in rats with experimentally induced brain tumor. Results showed inhibition and/or abrogation of tumor growth. Subsequent studies on cellular immunity also revealed potentiation of lymphocytes and PMNs at peripheral level. Presence of activated lymphocytes as revealed through flowcytometric analysis of CD25 expression evidenced infiltration of activated lymphocytes in the brain tumor tissues. The analysis of data suggests that T11TS or sheep form of LFA3 is capable of inhibiting/preventing tumor growth in rat brain by way of immunopotentiation (CMI) at the peripheral immune system and thereby facilitating infiltration of the activated lymphocytes into the brain cavity through the blood brain barrier.

Abstract
The close and constant association of allergic rhinitis (AR) and asthma, both in children and adults, is hardly mentioned in medical textbooks. Proper treatment is delayed, as these patients are often seen in rotation by chest physicians, allergy experts, otolaryngologists, general physicians and paediatricians. Even then treatment is directed mainly towards asthma with little attention being paid to associated rhinitis, often lying unrecognised in adults. The clinical pattern of asthma in children and adults differs in our country. Unless AR is treated simultaneously with asthma, recurrent AR will result likely in suboptimal control of asthma. Proof and arguement is brougnt forward to recognise the unified concept of nasobronchial allergy or rhinobronchitis for proper management.

Abstract
Fifty-one breast lumps were studied by fine needle aspiration cytology (FNAC) and scrape imprint cytology. Of the 51 cases, 28 were malignant and included infiltrating duct carcinoma (22), well differentiated adenocarcinoma (2), mucinous, papillary and lobular carcinoma (one each) and malignant lymphoma (one). Benign lesions were mastitis, fibroadenoma and fibrocystic disease. The diagnostic accuracy of FNAC was 90.2% and that of imprint 94.1% with no false negatives. Two imprint smears and one aspirate designated suspicious were proved to be benign. The combination of FNAC and imprint cytodiagnosis gave a diagnostic accuracy of 96% thus proving their value in the rapid diagnosis of breast lesions.
