Abstract
INTRODUCTION: Patients being treated for TB may suffer reductions in health-related quality of life (HRQoL). This study aims to assess the extent of such reductions and the trajectory of HRQoL over the course of treatment in rural Malawi.METHODS: We collected patient demographic and socioeconomic status, TB-related characteristics, and HRQoL data (i.e., EQ-5D and a visual analogue scale VAS) from adults (age ≥18 years) being treated for TB in 12 primary health centers and one hospital in rural Thyolo District, Malawi, from 2014 to 2016. Associations between HRQoL and patient characteristics were estimated using multivariable linear regression.RESULTS: Inpatients (n = 197) consistently showed lower median HRQoL scores and suffered more severe health impairments during hospitalization than outpatients (n = 156) (EQ5D and VAS: 0.79, 55 vs. 0.84, 70). Longer treatment duration was associated with higher HRQoL among outpatients (EQ5D: 0.034 increase per 2 months, 95%CI 0.012-0.057). We found no substantial associations between patients´ demographic and socioeconomic characteristics and HRQoL in this setting.CONCLUSION: HRQoL scores among patients receiving treatment for TB in rural Malawi differ by clinical setting and duration of treatment, with greater impairment among inpatients and those early in their treatment course.

Abstract
PURPOSE the aim of this study was to investigate the effect of shading on translucency and mean grain size of three Zirconia systems (Lava Frame, Ice Zirkon Translucent and Prettau Zirkon). MATERIALS AND METHODS specimens pigmented in A1, A4 and a non-pigmented specimen was evaluated with Scanning Electron Microscopy and spectrophotometery. RESULTS the transmittance ranged between 0.18 and 0.52, in Ice Zirkon Translucent A4 and Prettau Zircon non-pigmented, respectively. The pigmentation A1 and A4 significantly reduced the light transmission in all the systems evaluated (p⟨0.05), with the exception of Lava A1. The light transmittance of each ceramic system is different from each other in the three pigmentations, except for the Prettau Zirkon A1, which did not show a significant difference compared with Lava A1 (p⟩0.05). The mean grain size increased with pigmentation. The mean grain size ranged between 0.43 μm, for Prettau Zirkon non-pigmented, and 0.82 μm for Prettau Zirkon A4. CONCLUSION Light transmission and mean grain size was affected by pigmentation of dental zirconia ceramics.

Abstract
With the use of testicular sperm extraction (TESE), spermatozoa can be retrieved in about 30%-50% of men with Klinefelter syndrome (KS). The reason for the absence or presence of spermatozoa in half of the men with KS remains unknown. Therefore, the search for an objective marker for a positive prediction in finding spermatozoa is of significant clinical value to avoid unnecessary testicular biopsies in males with (mostly) low testicular volume and impaired testosterone. The objective of this study was to determine whether paternal or maternal inheritance of the additional X-chromosome can predict the absence or presence of spermatogenesis in men with KS. Men with KS who have had a testicular biopsy for diagnostic fertility workup TESE were eligible for inclusion. Buccal swabs from nine KS patients and parents (trios) were taken to compare X-chromosomal inheritance to determine the parental origin of both X-chromosomes in the males with KS. Spermatozoa were found in TESE biopsies 8 of 35 (23%) patients after performing a unilateral or bilateral TESE. Different levels of spermatogenesis (from the only presence of spermatogonia, up to maturation arrest or hypospermatogenesis) appeared to be present in 19 of 35 (54%) men, meaning that the presence of spermatogenesis not always yields mature spermatozoa. From the nine KS-trios that were genetically analysed for X-chromosomal inheritance origin, no evidence of a correlation between the maternal or paternal origin of the additional X-chromosome and the presence of spermatogenesis was found. In conclusion, the maternal or paternal origin of the additional X-chromosome in men with KS does not predict the presence or absence of spermatogenesis.

Abstract
Marine larval dispersal is a complex biophysical process that depends on the effects of species biology and oceanography, leading to logistical difficulties in estimating connectivity among populations of marine animals with biphasic life cycles. To address this challenge, the application of multiple methodological approaches has been advocated, in order to increase confidence in estimates of population connectivity. However, studies seldom account for sources of uncertainty associated with each method, which undermines a direct comparative approach. In the present study we explicitly account for the statistical uncertainty in observed connectivity matrices derived from elemental chemistry of larval mussel shells, and compare these to predictions from a biophysical model of dispersal. To do this we manipulate the observed connectivity matrix by applying different confidence levels to the assignment of recruits to source populations, while concurrently modelling the intrinsic misclassification rate of larvae to known sources. We demonstrate that the correlation between the observed and modelled matrices increases as the number of observed recruits classified as unknowns approximates the observed larval misclassification rate. Using this approach, we show that unprecedented levels of concordance in connectivity estimates (r = 0.96) can be achieved, and at spatial scales (20-40 km) that are ecologically relevant.

Abstract
BACKGROUND The appropriateness of rheumatic mitral valve repair remains controversial due to the risks of recurrent mitral dysfunction and need for reoperation. The aims of this study were to determine the overall short- and long-term outcomes of pediatric rheumatic mitral valve surgery in our center. METHODS Single-center, observational, retrospective study that analyzed the results of rheumatic mitral valve surgery in young patients, consecutively operated by the same team, between 1999 and 2014. RESULTS We included 116 patients (mean age = 12.6 ± 3.5 years), of which 66 (57%) were females. A total of 116 primary surgical interventions and 22 reoperations were performed. Primary valve repair was possible in 86 (74%) patients and valve replacement occurred in 30 (26%). Sixty percent of the patients were followed up beyond three months after surgery (median follow-up time = 9.2 months [minimum = 10 days; maximum = 15 years]). Long-term clinical outcomes were favorable, with most patients in New York Heart Association functional class I (89.6%) and in sinus rhythm (85%). Freedom from reoperation for primary valve repair at six months, five years, and ten years was 96.4% ± 0.25%, 72% ± 0.72%, and 44.7% ± 1.34%, respectively. Freedom from reoperation for primary valve replacement at six months, five years, and ten years was 100%, 91.7% ± 0.86%, and 91.7% ± 0.86%, respectively. Mitral stenosis as the primary lesion dictated early reintervention. CONCLUSIONS Despite the greater rate of reoperation, especially when the primary lesion was mitral stenosis, rheumatic mitral valve repair provides similar clinical outcomes as compared with replacement, with the advantage of avoiding anticoagulation.

Abstract
RNA-based body fluid and tissue identification has evolved as a promising and reliable new technique to classify type and source of biological evidence in crime cases. In particular, mRNA-based approaches are currently on the rise to replace conventional protein-based methods and are increasingly implemented into forensic casework. However, degradation of these nucleic acid molecules can cause issues on laboratory scale and need to be considered for a credible investigation. For this reason, the analysis of miRNAs using qPCR has been proposed to be a sensitive and specific approach to identify the origin of a biological trace taking advantage of their small size and resistance to degradation. Despite the straightforward workflow of this method, suitable endogenous controls are inevitable when performing real-time PCR to ensure accurate normalization of gene expression data in order to allow a meaningful interpretation. In this regard, we have validated reference genes for a set of forensically relevant body fluids and tissues (blood, saliva, semen, vaginal secretions, menstrual blood and skin) and tested 15 target genes aiming to identify abovementioned sample types. Our data showed that preselected endogenous controls (miR26b, miR92 and miR484) and miR144, initially selected as potential marker for the detection of menstrual blood, were the most stable expressed genes among our set of samples. Normalizing qPCR data with these four validated references revealed that only five miRNA markers are necessary to differentiate between the six different cell types selected in this study. Nevertheless, our observations in the present study indicate that miRNA analysis methods may not provide straightforward data interpretation strategies required for an implementation in forensic casework.

Abstract
The indiscriminate use of biocides for general disinfection has contributed to the increased incidence of antimicrobial tolerant microorganisms. This study aims to assess the potential of seven phytochemicals (tyrosol, caffeic acid, ferulic acid, cinnamaldehyde, coumaric acid, cinnamic acid and eugenol) in the control of planktonic and sessile cells of Staphylococcus aureus and Escherichia coli. Cinnamaldehyde and eugenol showed antimicrobial properties, minimum inhibitory concentrations of 3-5 and 5-12 mM and minimum bactericidal concentrations of 10-12 and 10-14 mM against S. aureus and E. coli, respectively. Cinnamic acid was able to completely control adhered bacteria with effects comparable to peracetic acid and sodium hypochlorite and it was more effective than hydrogen peroxide (all at 10 mM). This phytochemical caused significant changes in bacterial membrane hydrophilicity. The observed effectiveness of phytochemicals makes them interesting alternatives and/or complementary products to commonly used biocidal products. Cinnamic acid is of particular interest for the control of sessile cells.

Abstract
BACKGROUND AND PURPOSE Opioid receptor function is modulated by post-activation events such as receptor endocytosis, recycling and/or degradation. While it is generally understood that the peptide ligand gets co-endocytosed with the receptor, relatively few studies have investigated the role of the endocytosed peptide and peptide processing enzymes in regulating receptor function. In this study, we focused on endothelin-converting enzyme 2 (ECE2), a member of the neprilysin family of metallopeptidases that exhibits an acidic pH optimum, localizes to an intracellular compartment and selectively processes neuropeptides including opioid peptides in vitro, and examined its role in modulating μ receptor recycling and resensitization. EXPERIMENTAL APPROACH The effect of ECE2 inhibition on hydrolysis of the endocytosed peptide was examined using thin-layer chromatography and on μ opioid receptor trafficking using either elisa or microscopy. The effect of ECE2 inhibition on receptor signalling was measured using a cAMP assay and, in vivo, on antinociception induced by intrathecally administered opioids by the tail-flick assay. KEY RESULTS The highly selective ECE2 inhibitor, S136492, significantly impaired μ receptor recycling and signalling by only those ligands that are ECE2 substrates and this was seen both in heterologous cells and in cells endogenously co-expressing μ receptors with ECE2. We also found that ECE2 inhibition attenuated antinociception mediated only by opioid peptides that are ECE2 substrates. CONCLUSIONS AND IMPLICATIONS These results suggest that ECE2, by selectively processing endogenous opioid peptides in the endocytic compartment, plays a role in modulating opioid receptor activity.

Abstract
The European DNA Profiling Group (EDNAP) organized a fourth and fifth collaborative exercise on RNA/DNA co-analysis for body fluid identification and STR profiling. The task was to identify dried menstrual blood and vaginal secretion stains using specific RNA biomarkers, and additionally test 3 housekeeping genes for their suitability as reference genes. Six menstrual blood and six vaginal secretion stains, two dilution series (1/4-1/64 pieces of a menstrual blood/vaginal swab) and, optionally, bona fide or mock casework samples of human or non-human origin were analyzed by 24 participating laboratories, using RNA extraction or RNA/DNA co-extraction methods. Two novel menstrual blood mRNA multiplexes were used: MMP triplex (MMP7, MMP10, MMP11) and MB triplex (MSX1, LEFTY2, SFRP4) in conjunction with a housekeeping gene triplex (B2M, UBC, UCE). Two novel mRNA multiplexes and a HBD1 singleplex were used for the identification of vaginal secretion: Vag triplex (MYOZ1, CYP2B7P1 and MUC4) and a Lactobacillus-specific Lacto triplex (Ljen, Lcris, Lgas). The laboratories used different chemistries and instrumentation and all were able to successfully isolate and detect mRNA in dried stains. The simultaneous extraction of RNA and DNA allowed for positive identification of the tissue/fluid source of origin by mRNA profiling as well as a simultaneous identification of the body fluid donor by STR profiling, also from old and compromised casework samples. The results of this and the previous collaborative RNA exercises support RNA profiling as a reliable body fluid identification method that can easily be combined with current STR typing technology.

Abstract
We experimentally investigate the ghost resonance phenomenon in the electronic circuit of Chua operating in the chaotic regime. The circuit can be stimulated to jump between two single-scroll attractors by an external periodic signal with an amplitude above an intrinsic threshold. For subthreshold signals, jumps between the chaotic attractors can be promoted by a superposed white noise. We show that the circuit output can exhibit a well-defined ghost resonance signature, i.e., a resonance on a frequency that is absent in a multicomponent input signal, when the amplitudes of the input components are properly related. Further, we show that ghost resonance can be induced by the Chua's circuit's own chaotic dynamics when it is driven by a suprathreshold multicomponent signal without the need of an external noise source.

Abstract
OBJECTIVE To evaluate the effect of the consumption of green tea on components of MS in the elderly. DESIGN Intervention study. SETTING The sample was selected from the Geriatric Service of Hospital São Lucas of Pontifical Catholic University of Rio Grande do Sul. PARTICIPANTS 45 elderly with MS were enrolled and allocated into two groups: green tea group (GTG, n= 24), who drank green tea and control group (CG, n= 21) without intervention. INTERVENTION The GTG received sachets of 1.0 g of green tea, and should drink three cups per day for 60 days and the CG was instructed not to make changes in their lifestyle. MEASUREMENTS The diagnostic criteria for MS used were the International Diabetes Federation. The lipidic and glycemic profile, and anthropometric measurements were evaluated before and after intervention. RESULTS There was a statistically significant weight loss only in GTG [71.5±12.6 kg to 70.3±12.6 kg (p<0.001)]. A statistically significant decrease in BMI [-0.5±0.4 kg/m2 in GTG and -0.2±0.6 kg/m2 in CG (P=0.032)] and waist circumference [-2.2±2.0 cm in GTG and - 0.3±1.8 cm in CG (P=0.002)] were observed. The intake of green tea did not change the biochemical parameters. CONCLUSION The consumption of green tea was effective in inducing weight loss, reducing BMI and waist circumference in the elderly with MS.

Smoking habits start early and adolescence is a notorious time for starting smoking. AIM AND METHODS To assess knowledge on smoking and smoking habits in a population of adolescents in four Porto schools, using a confidential self administered questionnaire. Collected data were evaluated using the SPSS 1.2 statistics program (2004 version). RESULTS A total of 1,770 students aged 11 - 21 (median 15.1 years), mainly female, (58%), answered. Most students (n=952, 54.6%) were unaware of signs or warnings against smoking in their schools. The great majority (n=1639, 92.7%) considered themselves well informed on the harmful effects of smoking, but only 6.7% could list three or more tobacco-associated health consequences, however. Parents and friends were seen as privileged sources of information. Among these students, 194 (11.1%) were smokers and the average started to smoke at the age of 15. The majority of these (n=111, 57.2%) had parents who smoked and 96.4% had friends who smoked, versus 83.1% of non-smokers, a statistically significant difference (p < 0.001). Pocket money was the means of acquiring cigarettes in 34.8%. Most (60.8%) considered themselves able to stop smoking at any time, while 11.4% of the smokers smoked more than one pack a day and 9.8% smoked the first cigarette within 5 minutes of waking, however. CONCLUSIONS The percentage of smokers in this group of teenagers was considerable and indicators of nicotine dependence were found. Knowledge of the risks of smoking was poor and information on smoking given by schools had an apparently low and variable impact. Parents' and friends' behaviour may have a weighty impact on the decision to start smoking.

Abstract
UNLABELLED Nontuberculous mycobacteria (NTM) play an increasingly significant pathogenic role in HIV -positive patients, in patients with chronic lung disease, in other chronic conditions and in the elderly. AIMS Evaluate the importance of NTM isolation in respiratory samples in patients without HIV-infection. METHODS Retrospective evaluation of our hospital patients with no known AIDS, with at least one NTM positive respiratory sample, from 1997 -2004. RESULTS We found 102 patients, with a median age of 63 years; 67% male. Sixty -three (62%) had underlying lung disease, mainly tuberculosis sequelae (n=19). The majority (47%) of the isolations were Mycobacterium avium complex (MAC). A diagnosis of Mycobacterium pulmonary disease was made in 16 patients (15.7%), 14 of which met the American Thoracic Society diagnostic criteria. Ten male and 6 female; median age 65 years. Twelve had underlying lung disease. All of them had respiratory infection complaints. Chest X -rays showed mainly pulmonary infiltrates, linear opacities and cavitation. MAC was the cause of mycobacterium respiratory disease in 12 patients (75%). CONCLUSION NTM isolation did not equal pulmonary NTM disease in the majority of cases, even in patients with underlying lung disease. MAC was the most commonly isolated agent and its relative importance was higher in the presence of NTM disease.

Abstract
Cystic Fibrosis (CF) is the recessive autossomic disease more frequent in the caucasian race. The main characteristic is a mutation in CFTR, a trans-membranar protein, responsible for chlorates transportation. This protein has a diffuse epithelial distribution, which gives a multissistemic involvement to this disease, with clinical manifestations with variable degrees of severity. The development of better health care associated with new therapeutic options became responsible for an increase of survival, so CF is no longer a paediatric disease. Lung transplantation also has an important role, bringing new treatment perspectives. So, this pathology has an increased multi-disciplinary involvement in which the pulmonologist have a preponderant role.

Abstract
In this work, we present population genetic data of 10 X-chromosome STRs (DXS8378, DXS9898, DXS8377, HPRTB, GATA172D05, DXS7423, DXS6809, DXS7132, DXS101 and DXS6789) obtained from sample of 145 unrelated female individuals belonging to Valencia (Spain), a region located in the east of the Iberian Peninsula. All the markers studied present high genetic diversities, similar to those previously reported in other European population samples. No deviations from Hardy-Weinberg equilibrium were observed, with the exception of DXS101 locus. Allele frequencies and parameters of forensic interest for each X-STR were calculated. High mean exclusion chance and power of discrimination values were obtained by combining these 10 X-linked markers. Population comparisons (exact test of population differentiation; pairwise genetic distances) were carried out and low genetic distances were found between our sample and those from other Spanish or European regions.

Abstract
The long-term effects of low-level lead intoxication are not known. The sympathetic skin response (SSR) was evaluated in a group of 60 former workers of a primary lead smelter, located in Santo Amaro, BA, Brazil. The individuals participating in the study were submitted to a clinical-epidemiological evaluation including questions related to potential risk factors for intoxication, complaints related to peripheral nervous system (PNS) involvement, neurological clinical examination, and also to electromyography and nerve conduction studies and SSR evaluation. The sample consisted of 57 men and 3 women aged 34 to 69 years (mean +/- SD: 46.8 +/- 6.9). The neurophysiologic evaluation showed the presence of lumbosacral radiculopathy in one of the individuals (1.7%), axonal sensorimotor polyneuropathy in 2 (3.3%), and carpal tunnel syndrome in 6 (10%). SSR was abnormal or absent in 12 cases, representing 20% of the sample. More than half of the subjects (53.3%) reported a history of acute abdominal pain requiring hospitalization during the period of work at the plant. A history of acute palsy of radial and peroneal nerves was reported by about 16.7 and 8.3% of the individuals, respectively. Mean SSR amplitude did not differ significantly between patients presenting or not the various characteristics in the current neurological situation, except for diaphoresis. The results suggest that chronic lead intoxication induces PNS damage, particularly affecting unmyelinated small fibers. Further systematic study is needed to more precisely define the role of lead in inducing PNS injury.

Abstract
The authors reviewed adult cystic fibrosis patients followed in the Pulmonology Unit from 1994-2004 (n=8), five female and three male, aged 20-34 years old (median= 27 years). Patients were diagnosed at 18 months - 31 years old by sweat testing (positive in six patients) and genotyping (four patients homozygous for Delta F508 mutation). Respiratory involvement was characterised by sinusitis and bronchiectasis. Pulmonary involvement was accompanied by functional abnormalities and gas exchange impairment in the majority of the patients. Bronchial tree was colonised permanently in five patients: Pseudomonas aeruginosa in four and Staphilococcus aureus in four (three patients affected by both agents simultaneously). The main causes of exacerbation were respiratory infections and haemoptysis. Non-respiratory involvement was variable. Four patients had digestive involvement (one with hepatic cirrhosis), one had renal failure and only one had a sperm count to document infertility. Four patients had osteopaenia. Treatment included chest physiotherapy, bronchodilators, dornase alfa, mucolytics, digestive enzymes, vitamins, antibiotics and oxygen therapy. At review, one had left follow-up, one had died, one was awaiting lung transplant and the others evidenced no difference in clinical characteristics. In this group of patients the severity of the pulmonary disease was not related to a late diagnosis. It can be explained by the diversity of cystic fibrosis presentation in adults.

Abstract
AIM To report the effect of enzyme replacement therapy (ERT) in sympathetic skin responses (SSR) of patients with Fabry disease. PATIENTS AND METHODS Seven male patients were included in an open-label protocol using agalsidase-alfa, continued at regular intervals. Five patients completed 24 months of ERT and two of them completed 18 months. Two main measurements were performed at baseline, as well as 1 and 2 years after ERT: (1) a standard neurological examination (NE), with a detailed evaluation of the sensory perception of light touch, pinprick, cold, hot, and vibratory stimuli; (2) the SSR amplitudes. RESULTS Although there were no significant differences between NE in this time period, all patients reported general improvement in their subjective reports of acroparaesthesia and sweating. Before starting ERT, the SSR amplitudes were either too small (3/7 patients) or absent (4/7 patients): the average (range) amplitude of 122 microV (0 through 492) was statistically smaller than that found in a control group, i.e. 1453.6 microV (619.7-2754) (p<0.0001, t-test). Mean +/- SD SSR amplitude increased to 1088+/- 690 microV in the second year of ERT, reaching the range found in a normal control group (p=0.004). CONCLUSION ERT improved SSR continuously in Fabry patients in 2 years of observation. Although the mechanism of the SSR improvement is unknown, this response to ERT can be clinically significant if it reflects a normalization in sweating.

Abstract
A collaborative work was carried out by the Spanish and Portuguese ISFG Working Group (GEP-ISFG) to estimate Y-STR mutation rates. Seventeen Y chromosome STR loci (DYS19, DYS385, DYS389I and II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460, DYS461, DYS635 [GATA C4], GATA H4, and GATA A10) were analyzed in a sample of 3,026 father/son pairs. Among 27,029 allele transfers, 54 mutations were observed, with an overall mutation rate across the 17 loci of 1.998 x 10(-3) (95% CI, 1.501 x 10(-3) to 2.606 x 10(-3)). With just one exception, all of the mutations were single-step, and they were observed only once per gametogenesis. Repeat gains were more frequent than losses, longer alleles were found to be more mutable, and the mutation rate seemed to increase with the father's age. Hum Mutat 26(6), 520-528, 2005.

Abstract
Adrenergic and opioid receptors belong to the rhodopsin family of G-protein coupled receptors, couple to analogous signal transduction pathways, and affect the nociceptive system. Although a number of previous studies have reported functional interactions between these two receptors, the basis for this has not been well explored. We propose that direct receptor-receptor interactions could account, in part, for opioid-adrenergic cross-talk. In this report, we have addressed this using biophysical, biochemical, and pharmacological studies. We show that mu opioid and alpha2A adrenergic receptors reside in close proximity in live cells using the bioluminescence resonance energy transfer assay. These receptors colocalize to proximal dendrites in primary hippocampal neurons. mu-alpha2A Receptor complexes can be isolated from heterologous cells or primary neurons coexpressing these receptors. In these cells, the activation of either mu or alpha2A receptor leads to a significant increase in the level of immunoprecipitable mu-alpha2A complexes, whereas activation of both receptors leads to a significant decrease. The implications of these effects on signaling were examined using the agonist-mediated increase in G-protein activity and mitogen-activated protein kinase activity. We find that activation of either mu or alpha2A receptors leads to an increase in the extent of signaling, whereas activation of both receptors leads to a decrease. The increase in signaling by individual ligands and decrease by a combination of ligands is also seen in primary spinal cord neurons endogenously expressing these receptors. Taken together, these results suggest that physical associations between mu and alpha2A receptors could play a role in the functional interactions between these receptors.

Abstract
Five strains of the extreme thermophilic Rhodothermus marinus were screened for the production of amylolytic and pullulytic activities. The culture medium for the selected strain, R. marinus ITI 990, was optimized using central composite designs for enhanced enzyme production. The optimized medium containing 1.5 gl(-1) of maltose and 8.3 gl(-1) of yeast extract yielded amylase, pullulanase and alpha-glucosidase activities of 45, 33 and 2.1 nkatml(-1), respectively. Among the various carbon sources tested, maltose was most effective for the formation of these enzymes, followed by soluble maize starch, glycogen and pullulan. The crude amylase and pullulanase showed maximum activities at pH 6.5-7.0, and 85 and 80 degrees C, respectively. At 85 degrees C amylase and pullulanase had half lives of 3 h and 30 min, respectively.

Abstract
G-protein-coupled receptors (GPCRs) comprise the largest family of transmembrane receptors in the human genome that respond to a plethora of signals, including neurotransmitters, peptide hormones, and odorants, to name a few. They couple to second messenger signaling cascade mechanisms via heterotrimeric G-proteins. Recently, many studies have revealed that GPCRs exist as dimers, which may be present as homo- or heterodimers/oligomers. These recent findings have been met with skepticism, since they are contradictory to the dogma that GPCRs function as monomers. Although the existence of GPCR dimers/oligomers was predicted from early pharmacological and biochemical studies, further studies to critically evaluate this phenomenon were impeded by the lack of appropriate reagents. The availability of cDNAs for GPCRs, of highly selective ligands and of antibodies for these receptors has made it possible to visualize and investigate the functional effects of GPCR oligomers. Pharmacological studies, along with biochemical techniques, such as cross-linking and immunoprecipitation with differentially epitope-tagged receptors, have been employed to demonstrate the oligomerization of a number of GPCRs. Moreover, recent biophysical techniques, such as bioluminescence and fluorescence resonance energy transfer, now make it possible to examine GPCR dimerization/oligomerization in living cells. In this review, we provide a brief overview of some of the techniques employed to describe GPCR dimers, and we discuss their respective limitations. We also examine the implications of dimerization/oligomerization on GPCR function. In addition, we discuss domains of the receptors that are thought to facilitate dimerization/oligomerization. Finally, we consider recent evidence for the subcellular localization of the dimer/oligomer assembly.

Abstract
Interstitial deletion or loss of chromosome 5, del(5q) or -5, is a frequent finding in myeloid leukemias and myelodysplasias, suggesting the presence of a tumor suppressor gene within the deleted region. In our search for this gene, we identified a candidate, 5qNCA (LOC51780), which lies within a consistently-deleted segment of 5q31. 5qNCA expresses a 7.2-kb transcript with a 5286-bp open reading frame which is present at high levels in heart, skeletal muscle, kidney, placenta, and liver as well as CD34+ cells and AML cell lines. 5qNCA encodes a 191-kD nuclear protein which contains a highly-conserved C-terminus containing a zinc finger with the unique spacing Cys-X2-Cys-X7-His-X2-Cys-X2-Cys-X4-Cys-X2-Cys and a jmjC domain, which is often found in proteins that regulate chromatin remodeling. Expression of 5qNCA in a del(5q) cell line results in suppression of clonogenic growth. Preliminary sequence results in AML and MDS samples and cell lines has revealed a possible mutation in the KG-1 cell line resulting in a THR to ALA substitution that has not been found in over 100 normal alleles to date. We propose 5qNCA is a good candidate for the del(5q) tumor suppressor gene based on its predicted function and growth suppressive activities, and suggest that further mutational and functional study of this interesting gene is warranted.
