Abstract
Tuberculosis (TB) is the leading global cause of death from a single infectious agent. Registered incidence rates are low, especially in low-resource countries with weak health systems, due to the disadvantages of current diagnostic techniques. A major effort is directed to develop a point-of-care (POC) platform to reduce TB deaths with a prompt and reliable low-cost technique. In the frame of the European POCKET Project, a novel POC platform for the direct and noninvasive detection of TB in human urine was developed. The photonic sensor chip is integrated in a disposable cartridge and is based on a highly sensitive Mach-Zehnder Interferometer (MZI) transducer combined with an on-chip spectral filter. The required elements for the readout are integrated in an instrument prototype, which allows real-time monitoring and data processing. In this work, the novel POC platform has been employed for the direct detection of lipoarabinomannan (LAM), a lipopolysaccharide found in the mycobacterium cell wall. After the optimization of several parameters, a limit of detection of 475 pg/mL (27.14 pM) was achieved using a direct immunoassay in undiluted human urine in less than 15 min. A final validation of the technique was performed using 20 clinical samples from TB patients and healthy donors, allowing the detection of TB in people regardless of HIV coinfection. The results show excellent correlation to those obtained with standard techniques. These promising results demonstrate the high sensitivity, specificity and applicability of our novel POC platform, which could be used during routine check-ups in developing countries.

Abstract
Allergic asthma is a chronic inflammatory disease characterized by the accumulation of eosinophils, Th2 cells and mononuclear cells in the airways, leading to changes in lung architecture and subsequently reduced respiratory function. We have previously demonstrated that CDIP-2, a chemokine derived peptide, reduced in vitro chemotaxis and decreased cellular infiltration in a murine model of allergic airway inflammation. However, the mechanisms involved in this process have not been identified yet. Now, we found that CDIP-2 reduces chemokine-mediated functions via interactions with CCR1, CCR2 and CCR3. Moreover, using bone marrow-derived eosinophils, we demonstrated that CDIP-2 modifies the calcium fluxes induced by CCL11 and down-modulated CCR3 expression. Finally, CDIP-2 treatment in a murine model of OVA-induced allergic airway inflammation reduced leukocyte recruitment and decreases production of cytokines. These data suggest that chemokine-derived peptides represent new therapeutic tools to generate more effective antiinflammatory drugs.

Abstract
Long before the fountain of youth, mankind has had an interest in staying young. As we move into the 21st century, that interest has not only continued, but it has become an obsession. While no one can really prevent normal, chronological aging, there are things we can do to slow down "pathological aging." After all, aging is about accelerated inflammation, depletion, and wear and tear. With the marked increase in life expectancy and life span, clinicians need to be aware of the effects of aging on the provision of treatment modalities. Appropriate interventions individualized to the patient can help to "compress morbidity" by shortening the period of functional decline common in old age. Therefore, the "health span" will come closer to matching the life span. Disease and disuse are far more likely explanations for functional decline and the onset of common chronic conditions in older persons than is "true" natural or normal aging. Regardless of your genetic inheritance, you can accelerate aging by lifestyle choices and environmental conditions to which you expose your genes. There are even ways to reverse the problems associated with aging. Getting older does not have to mean growing older. Welcome to the world of preventative gerontology, better known as anti-aging medicine!

Abstract
During evolution, DNA viruses have captured a broad array of cellular genes involved in immune recognition and growth control that are nonessential for viral replication. The encoded virokines and viroceptors may act as mimetics or antagonists of their cellular homologues, altering signal transduction and cell communication towards survival of virus-infected cells. Human herpesvirus type 8 (HHV8) is the most recently identified human oncogenic herpesvirus. It is associated with Kaposi's sarcoma and lymphoproliferative diseases, such as pleural effusion lymphomas and multicentric Castleman's disease. HHV8 has captured a unique number of cellular regulatory genes, which redirect gene expression and cell growth, prevent apoptosis and immune recognition, and interfere with tumor suppressor gene function. HHV8 encodes a unique virokine, viral interleukin-6, which is particularly relevant for the pathogenesis of HHV8-associated tumors, since it participates in transformation and mediates autocrine and paracrine mitogenic and proinflammatory effects. Viral IL-6 differs fundamentally from human IL-6 in receptor engagement for signal transduction and thus constitutes a singular model to understand the facets of human and viral cytokine biology. We provide an overview of the role of virokines in cancer, with a particular focus on the differences of human and viral IL-6 in the pathophysiology of HHV8-associated tumors.

Abstract
Mu opioid receptors (MOR) mediate the analgesic effects of opioid drugs such as morphine. The opioid receptor-like (ORL-1) receptor is structurally related to opioid receptors and the ORL-1 receptor agonist, orphanin FQ/nociceptin, induces analgesia at the spinal level, but appears to recruit different circuitry than that used by mu opioids. When administered intracerebroventricularly, orphanin FQ/nociceptin produces hyperalgesia and/or reverses opioid analgesia. The functionally distinct actions elicited by MOR and ORL-1 receptors, which activate similar intracellular signaling systems and show similar regional distributions, could be explained by their differential cellular localization. By using double label immunohistochemistry and confocal microscopy, the present study investigates the distribution of MOR and ORL-1 receptors in regions of the rat nervous system that are involved with nociceptive processing. In general co-localization of MOR and ORL-1 receptor immunoreactivity was not observed in either perikarya or neuropil in the dorsal root ganglia, nor in the Lissauer's tract and superficial laminae of the spinal cord. Likewise, there was no evidence for co-localization of these receptors within the periaqueductal gray, the nucleus raphe magnus, the gigantocellular reticular nucleus, and the nucleus of the solitary tract. These observations indicate that MOR and ORL-1 receptors are expressed predominantly on different fiber systems in these regions. This differential distribution is consistent with the distinct pharmacology of ORL-1 and MOR receptor agonists and suggests that the antisera to MOR and ORL-1 receptors may provide useful markers for further investigations of analgesic and counteranalgesic pathways modulating pain perception.

Abstract
The present study utilized a newly developed quantitative immunohistochemical assay to measure changes in mu opioid receptor abundance following chronic administration of the opioid receptor antagonist naltrexone. These data were compared with those obtained from mu receptor radioligand binding on adjacent tissue sections, in order to determine whether the characteristic antagonist-induced increase in radioligand binding is due to an increase in the total number of mu receptors and/or to an increase in the proportion of receptors that are in an active binding conformation in the absence of a change in the total number of receptors. Adult male Sprague-Dawley rats were administered naltrexone, 7-8 mg/kg per day, or saline continuously for seven days by osmotic minipumps, after which time their brains were processed for immunohistochemistry and receptor autoradiography on adjacent fresh frozen tissue sections. Semiquantitative immunohistochemistry was performed using a radiolabelled secondary antibody for autoradiographic determination and a set of radioactive standards. Results demonstrate an overall concordance between the distribution of mu opioid receptors as measured by the two different methods with a few exceptions. Following naltrexone administration, mu receptor immunoreactivity was significantly higher in the amygdala, thalamus, hippocampus, and interpeduncular nucleus as compared with the saline-treated control animals. [3H]D-Ala2,N-Me-Phe4,Gly-ol5-enkephalin binding to mu opioid receptors was significantly higher in the globus pallidus, amygdala, thalamus, hypothalamus, hippocampus, substantia nigra, ventral tegmental area, central gray, and interpeduncular nucleus of the naltrexone-treated rats. These findings indicate that in some brain regions chronic naltrexone exposure increases the total number of mu opioid receptors, while in other regions there is an increase in the percent of active receptors without an observable change in the total number of receptors. Quantitative receptor immunodetection together with ligand autoradiography provides a new approach for investigating the regulation of mu opioid receptors on tissue sections.

Abstract
mu-Opioid receptors are the pharmacological targets of endogenous opioid peptides and morphine-like alkaloid drugs. Previous studies of transfected cells and peripheral neurons indicate that opioid receptors are rapidly internalized after activation by the alkaloid agonist etorphine but not after activation by morphine. To determine whether opioid receptors in the central nervous system are regulated by a similar process of agonist-selective internalization, mu-opioid receptors were examined in rat brain neurons after treatment of animals with opioid drugs. Internalized mu receptors were observed within 30 min after intraperitoneal injection of the alkaloid agonist etorphine, and this process was blocked by the antagonist naloxone. Colocalization of internalized opioid receptors with transferrin receptors in confocal optical sections indicated that receptor internalization observed in vivo is mediated by a membrane trafficking pathway similar to that observed previously in vitro using transfected human embryonic kidney 293 cells. Morphine failed to induce detectable rapid internalization of receptors, even when administered to animals at doses far in excess of those required to induce analgesia. To quantify these agonist-selective differences and to analyze an array of opioid ligands for their ability to trigger internalization, we used flow cytometry on stably transfected 293 cells. These studies indicated that the different effects of individual agonists are not correlated with their potencies for receptor activation and that a variety of clinically important agonists differ significantly in their relative abilities to stimulate the rapid internalization of opioid receptors.

Abstract
Growth-associated phosphoprotein B-50 is a neural protein kinase C (PKC) substrate enriched in nerve growth cones that has been implicated in growth cone plasticity. Here we investigated whether B-50 is a physiological substrate for casein kinase II (CKII) in purified rat cortical growth cone preparations. Using site-specific proteolysis and known modulators of PKC, in combination with immunoprecipitation, mass spectrometry, and phosphoamino acid analysis, we demonstrate that endogenous growth cone B-50 is phosphorylated at multiple sites, on both serine and threonine residues. Consistent with previous reports, stimulation of PKC activity increased the phosphorylation of only those proteolytic fragments containing Ser41. Under basal conditions, however, phosphorylation was predominantly associated with fragments not containing Ser41. Mass spectrometry of tryptic digests of B-50, which had been immunoprecipitated from untreated growth cones, revealed that in situ phosphorylation occurs within peptides B-50(181-198) and B-50(82-98). These peptides contain the major and minor in vitro CKII phosphosites, respectively. In addition, cyanogen bromide digestion of immunoprecipitated chick B-50 generated a 4-kDa C-terminal B-50 phosphopeptide, confirming that phosphorylation of the CKII domain occurs across evolutionary diverse species. We conclude that B-50 in growth cones is not only a substrate for PKC, but also for CKII.

Abstract
Parallel studies have demonstrated that enkephalin release from nerve terminals in the pallidum (globus pallidus and ventral pallidum) can be modulated by locally applied opioid drugs. To investigate further the mechanisms underlying these opioid effects, the present study examined the presynaptic and postsynaptic localization of delta (DOR1) and mu (MOR1) opioid receptors in the dorsal and ventral striatopallidal enkephalinergic system using fluorescence immunohistochemistry combined with anterograde and retrograde neuronal tracing techniques. DOR1 immunostaining patterns revealed primarily a postsynaptic localization of the receptor in pallidal cell bodies adjacent to enkephalin- or synaptophysin-positive fiber terminals. MOR1 immunostaining in the pallidum revealed both a presynaptic localization, as evidenced by punctate staining that co-localized with enkephalin and synaptophysin, and a postsynaptic localization, as evidenced by cytoplasmic staining of cells that were adjacent to enkephalin and synaptophysin immunoreactivities. Injections of the anterograde tracer Phaseolus vulgaris leucoagglutinin (PHA-L) or the retrograde tracer Texas Red-conjugated dextran amine (TRD) into the dorsal and ventral striatum resulted in labeling of striatopallidal fibers and pallidostriatal cell bodies, respectively. DOR1 immunostaining in the pallidum co-localized only with TRD and not PHA-L, whereas pallidal MOR1 immunostaining co-localized with PHA-L and not TRD. These results suggest that pallidal enkephalin release may be modulated by mu opioid receptors located presynaptically on striatopallidal enkephalinergic neurons and by delta opioid receptors located postsynaptically on pallidostriatal feedback neurons.

Abstract
Organizational diagnosis views the organization as a single entity with problems and challenges that are unique to the organization as a whole. This paper describes the process of establishing organizational diagnoses related to computer and information learning needs within a clinical or academic health care institution. The assessment of a college within a state-owned university in the U.S.A. is used to demonstrate the process of organizational diagnosis. The diagnoses identified include the need to improve information seeking skills and the information presentation skills of faculty.

Abstract
Alterations in the brain of rats receiving a single non-convulsive administration pentylenetetrazol (PTZ), 30 mig/kg, i.p. (single PTZ group) were investigated and compared with those detected in fully PTZ kindled rats (chronic PTZ group). In vitro receptor autoradiography experiments showed that both single and chronic PTZ groups presented mu opioid and benzodiazepine (BDZ) receptor binding in specific brain areas. Using an antibody generated against the delta opioid receptor (DOR-1), it was found that DOR-1 like immunoreactivity was reduced in cortex and amygdala in mice following single and chronic PTZ administration. Microdialysis experiments revealed that the administration of PTZ 30 mg/kg, i.p. in freely moving rats without previous experience with the drug, induces a rise in glutamate release, detected in the first and second 10 min dialysates collected from amygdala (138% and 50%, respectively) and frontal cortex (70% and 45%, respectively) as well as aspartate in frontal cortex in the first and second PTZ-dialysates (143% and 80%, respectively). Subsequently, values returned to basal conditions. It may be speculated that decreased BDZ receptor binding results from enhanced release of GABA. On the other hand, the decrease of mu receptor binding and DOR-1 immunoreactivity observed after PTZ administration may be the result of enhanced levels of opioid peptides probably released over the kindling procedure. In conclusion, the present study indicates that PTZ-kindling is associated with an imbalance between excitatory and inhibitory systems which is apparent early in the epileptogenic process.

Abstract
Highly reflective LaF(3)/MgF(2) systems for a wavelength of 248 nm on MgF(2) and crystalline quartz substrates were investigated. The influence of laser conditioning on damage threshold and absorptance was remarkable in those coatings that had a high initial absorptance. Monitoring with a laser calorimeter revealed the conditioning effect to be a function of the irradiation dose rather than of energy density or pulse rate. Furthermore, x-ray photoelectron spectroscopy and transmission electron microscopy investigations showed that conditioning induces stoichiometric and structural changes in the multilayers, especially in near-surface sublayers, whereas scanning electron microscopy and atomic force microscopy investigations indicated that the surface remains unchanged.

Abstract
Opiate alkaloids are potent analgesics that exert multiple pharmacological effects in the nervous system by activating G protein-coupled receptors. Receptor internalization upon stimulation may be important for desensitization and resensitization, which affect cellular responsiveness to ligands. Here, we investigated the agonist-induced internalization of the mu opioid receptor (MOR) in vivo by using the guinea pig ileum as a model system and immunohistochemistry with an affinity-purified antibody to the C terminus of rat MOR. Antibody specificity was confirmed by the positive staining of human embryonic kidney 293 cells transfected with epitope-tagged MOR cDNA, by the lack of staining of cells transfected with the delta or kappa receptor cDNA, and by the abolition of staining when the MOR antibody was preadsorbed with the MOR peptide fragment. Abundant MOR immunoreactivity (MOR-IR) was localized to the cell body, dendrites, and axonal processes of myenteric neurons. Immunostaining was primarily confined to the plasma membrane of cell bodies and processes. Within 15 min of an intraperitoneal injection of the opiate agonist etorphine, intense MOR-IR was present in vesicle-like structures, which were identified as endosomes by confocal microscopy. At 30 min, MOR-IR was throughout the cytoplasm and in perinuclear vesicles. MOR-IR was still internalized at 120 min. Agonist-induced endocytosis was completely inhibited by the opiate antagonist naloxone. Interestingly, morphine, a high-affinity MOR agonist, did not cause detectable internalization, but it partially inhibited the etorphine-induced MOR endocytosis. These results demonstrate the occurrence of agonist-selective MOR endocytosis in neurons naturally expressing this receptor in vivo and suggest the existence of different mechanisms regulating cellular responsiveness to ligands.

Abstract
We recently demonstrated the efficacy of a nonreplicating herpes simplex type 1 virus construct, employing the Moloney murine leukemia virus long terminal repeat promoter, in providing long-term expression of the lacZ gene in rat hippocampal neurons. We now report the utility of this construct in expressing the reporter gene in neurons of the basal forebrain and substantia nigra and examine the spread of the virus to other brain regions. Dorsal and ventrolateral hippocampal formation injection of the virus resulted in numerous beta-gal-expressing cells in the stratum pyramidale, stratum oriens, stratum lacunosum-moleculare, and stratum granulosum. Scattered cells of the medial septum/diagonal band were positively stained following direct injection into this region. More intense staining of the basal forebrain was observed following hippocampal injection as a result of retrograde transport of the virus as shown by PCR analysis of viral DNA. Hippocampal injection also resulted in positive cell staining in several other afferent projection nuclei, namely, the supramammillary bodies, dorsal and caudal linear raphe, and perirhinal/entorhinal cortex. Very few cells were labeled around injection sites in the striatum or substantia nigra. However, substantia nigra zona compacta cells were blue following striatal injection, as were pallidal neurons following nigral injection. These data demonstrate the feasibility of using this virus construct to express foreign genes such as neurotrophic factors in basal forebrain and substantia nigra neurons, taking advantage of retrograde transport of the virus to preserve local anatomy.

Abstract
A novel member of the opioid receptor family (ORL-1) has been cloned from a variety of vertebrates. ORL-1 does not bind any of the classical opioids, although a high affinity endogenous agonist with close homology to dynorphin has recently been identified. We have generated a monoclonal antibody to the N-terminus of ORL-1 to map areas of receptor expression in rat central nervous system (CNS). Intense and specific immunolabeling was observed in multiple areas in the diencephalon, mesencephalon, pons/medulla, and spinal cord. In the telencephalon, intense labeling was observed in the neuropil throughout layers II-V in the neocortex, the anterior olfactory nuclear complex, the pyriform cortex, the CA1-CA4 fields and dentate gyrus of the hippocampus, and in many of the septal and basal forebrain areas. In contrast to other members of the opioid receptor family, light labeling for ORL-1 was observed in telencephalic areas such as caudate-putamen. In the cerebellum, ORL-1 immunoreactivity was only observed in the deep nuclei. Throughout the CNS the majority of labelling was localized to fiber processes and fine puncta, although labeled scattered perikarya were observed in a few brain areas such as the hilus dentate in the hippocampus and some nuclei in the brainstem and spinal cord. The present mapping study is consistent with the reported distribution of ORL-1 mRNA and provides the first immunohistochemical report on anatomical and cellular distribution of ORL-1 receptor in the rat CNS.

Abstract
The analgesic and addictive properties of morphine and other opioid drugs are thought to result from their interaction with mu opioid receptors. Using a delta opioid receptor cDNA as a probe, we have isolated a murine mu opioid receptor cDNA clone (mMOR). Stable expression of mMOR in Chinese hamster ovary cells conferred high binding affinity for mu receptor ligands including morphine and [D-Ala2,N-methyl-Phe4,Gly5-ol]-enkephalin and low affinity for delta and kappa preferring ligands. Treatment of these cell lines with morphine and other mu agonists inhibited forskolin-induced cAMP accumulation, demonstrating a functional coupling of mMOR to the inhibition of adenylate cyclase. The predicted amino acid sequence of mMOR shares approximately 55% overall amino acid identity with the delta receptor and approximately 97% identity with the recently reported rat mu opioid receptor. Expression of the mu receptor in mouse brain as revealed by in situ hybridization parallels the reported pattern of distribution of mu-selective ligand binding sites. Chromosomal localization (to mouse chromosome 10) and Southern analysis are consistent with a single mu opioid receptor gene in the mouse genome, suggesting that the various pharmacologically distinct forms of the mu receptor arise from alternative splicing, post-translational events, or from a highly divergent gene(s).

Abstract
OBJECTIVE To evaluate the long-term survival of critically ill patients with sepsis and to assess the factors predictive of long-term survival (> 1 month after admission date). DESIGN Prospective, cohort study. SETTING Medical/surgical intensive care unit (ICU) in a multidisciplinary community hospital. PATIENTS All patients admitted to the ICU from January 1, 1987 to March 31, 1991 who both demonstrated clinical evidence of the systemic inflammatory response syndrome and yielded blood cultures positive for a bacterium or fungus (n = 153). INTERVENTIONS Random set of procedures normally performed in an ICU setting. MEASUREMENTS AND MAIN RESULTS Patient characteristics, including age, blood culture results, comorbid conditions, and severity of illness as estimated by the Acute Physiology Score of the Acute Physiology and Chronic Health Evaluation II prognostic system were recorded. Follow-up evaluation utilizing the National Death Index provided survival outcome for all patients 1 yr after hospital discharge. The mortality rate at hospital discharge was 51.0%, and mortality rates at 1 month, 6 months, and 1 yr after admission date were 40.5%, 64.7%, and 71.9%, respectively. A total of 33 patients survived beyond the period of observation. The analyses demonstrated the following findings: a) the survival rate was negatively correlated with the Acute Physiology Score up to 1 month after hospital admission date, but uncorrelated thereafter; b) fungal infections, such as Candida, had the shortest survival prospects of any blood-borne infection; and c) both malignancy and human immunodeficiency virus infection contributed to poorer outcomes, but differed in their patterns of long-term survival. CONCLUSIONS The most critical period for surveillance of bacteremic patients was in months 2 through 6 after discharge, during which time, the percentage of patients surviving decreased dramatically. The degree of physiologic derangement, as measured by the Acute Physiology Score, was a useful measure of prognosis within the first month after the score was assessed at ICU admission. However, beyond this period, prognostic utility decreased significantly. Healthcare providers should use caution concerning the expected survival of hospitalized patients with human immunodeficiency virus, based on experience with distinct conditions, such as malignancies.

Abstract
We have used a retroviral cDNA expression system to drive the expression of the different forms of glutamic acid decarboxylase (GAD65, GAD67, or both). Individual clones of engineered Rat-1 cells make the appropriate GAD mRNAs and GAD polypeptides, show GAD enzymatic activity, and make GABA. Clones expressing GAD65 had higher enzymatic activity than those expressing GAD67. As is the case for brain GADs and for GADs produced in engineered bacteria, the enzymatic activity of GAD65 is more responsive to added pyridoxal phosphate than that of GAD67. Immunostaining for both GADs is scattered throughout the cytoplasm. GAD65 immunostaining is less homogeneous than that of GAD67 and also appears to be associated with the surfaces of large vesicle-like structures. Cells expressing GAD65 and GAD67 showed similar immunostaining patterns with anti-GABA antibodies and contained substantial amounts of GABA (ranging from 7 to 18 pmol of GABA/10(6) cells), which was roughly proportional to their levels of GAD activity. GABA is released from the engineered cells into the surrounding medium under resting conditions, suggesting that cells programmed with GAD cDNAs might serve as effective sources of GABA in cell transplantation experiments.

Abstract
To determine the frequency and distribution of pneumonia in an intensive care unit (ICU), we retrospectively examined the records of 1,854 consecutive ICU admissions between January 1987 and April 1990. A total of 266 patients met criteria for pneumonia (unilateral or bilateral infiltrate by chest roentgenogram, plus 2 of the following: leukocyte count > 10 x 10(9) per liter, temperature > 38.5 degrees C, or culture of blood or sputum positive for pathogens). Pneumocystis carinii pneumonia in patients infected with the human immunodeficiency virus was the most frequent cause (28%) precipitating an ICU admission in this series of patients. Streptococcus pneumoniae (13%), Staphylococcus aureus (8%), Haemophilus influenzae (4%), and viruses (4%) were also commonly observed. Overall mortality was 20%. An APACHE II score of greater than 24, the need for intubation, and the presence of P carinii were predictive of increased mortality. Age, sex, and length of stay did not predict final results. Patients with P carinii pneumonia who required intubation had an overall mortality of 54%, which was higher than patients without P carinii pneumonia who required intubation (P < .05). Our experience shows the changing spectrum of pneumonia in ICUs. In contrast to reports of a decade ago in which S pneumoniae and Pseudomonas aeruginosa are cited as most common, P carinii is now most prevalent in our ICU. Although our findings reflect the increasing incidence of human immunodeficiency virus infection in San Francisco, California, they may also be pertinent to other areas in the United States where the incidence of this infection continues to increase.
