Prophage 2 of strain

Prophage 2 of strain activator Ivacaftor T5T is a Mu-like bacteriophage, not present in strain DSM 17395. It was previously shown that strain T5T produces two different AHLs, i.e. C18-en-HSL and N-3-hydroxydecanoyl-homoserine lactone (3OHC10-HSL) [76]. In P. inhibens strain DSM 17395 TDA and pigment production are regulated via a pgaR-pgaI QS system [47]. The AHL synthase encoding gene pgaI in DSM 17395 is responsible for the production of 3OHC10-HSL. In the genome of strain T5T we found a homologous system probably coding for the 3OHC10-HSL producing AHL synthase (Inhi_2120, homolog to pgaI) and the respective regulator (Inhi_2121, homologous to pgaR) (Figure 3, QS system I). Thus TDA production in strain T5T might also be regulated by a QS system. In addition, two further QS systems (QS system II and III; Figure 3) were found on the chromosome of T5T.

System II is formed by the genes Inhi_0506 and _0507 and is located in the prophage region 2. Orthologs for these QS system genes are also present in P. inhibens strain DSM 24588 (PGA2_c18960 and PGA2_c18970) but absent in strain DSM 17395. QS system III consists of the genes Inhi_1819 and _1820 and is unique for strain T5T compared to P. inhibens DSM 17395 and DSM 24588. It is also located in the potential prophage 1 region (Fig. 3). A homologous system was found in the genome of Phaeobacter caeruleus DSM 24564T and the neighboring genes show a high synteny. The location in the prophage region and the high synteny to the system of P. caeruleus suggest a possible gene transfer of this QS system via a bacteriophage.

The functions of QS system II and III are currently unknown, but it is likely that the compound C18-en-HSL is produced by one of those systems. Two functions were suggested that can possibly be used as unique chemotaxonomic markers for the species P. inhibens within the Roseobacter clade [3]. The genes coding for the first of these functions are located on the chromosome and are involved in cell wall development and surface attachment [dltA encoding a D-alanine-poly(phosphoribitol) ligase involved in biosynthesis of D-alanyl-lipoteichoic acid]. The second unique function is the biosynthesis and transport of iron-chelating siderophores, and the encoding genes are located on the plasmid pPGA1_78 and pPGA2_95, respectively. These two clusters are also present in the genome of strain T5T.

The siderophore gene cluster (Inhi_3924 �C Inhi_3928) is located on the 78 kb plasmid (Fig. 3) and the dltA gene cluster (Inhi_1065 – Inhi_1086) is located on the chromosome (Fig. 3). Screenings in the newly available Roseobacter genomes showed that Leisingera methylohalidivorans DSM 14336 [42] and Leisingera aquimarina DSM 24565 [41] also harbor the genes for siderophore synthesis. The uniqueness of the dltA gene cluster within Batimastat the species P. inhibens, however, remains and can be used as chemotaxonomic marker.

The 5mm wide angle optics allows having a very good operative vie

The 5mm wide angle optics allows having a very good operative view equivalent to a usual 10mm optic used in laparoscopic surgery. Narrower optics could be developed in the future. The length of this procedure is slightly longer than the usual technique due to the transgastric removal and the gastric closure. In our these experience, the after effects are very simple without early or late abdominal wall and gastric complications in the followup. The patients resumed normal activity quickly. The esthetic result is perfect with minute skin incisions. The risk of gastric complications is very low in the context of a nonpathological gastric wall but will be the object of a more accurate assessment. There are some difficulties with the gall bladder removal in cholecystitis and very large gall stones (larger than 3cm).

It could be overcome by carrying out endoscopic control of the removal with or without a specific cover. This endoscopic control could also be interesting in the presence of a hiatus hernia, an oesophagitis, and so forth. 5. Conclusion Our procedure (laparoscopic cholecystectomy using micro instruments and a 5mm optic in a transgastric gall bladder removal) allows abdominal wall trauma reduction and to resume as soon as possible normal physical activity without risk of incisional hernia. The cystic pediclar dissection is a usual and standardized procedure. The hand sewn gastrostomy is safer than N.O.T.E.S. and endoscopic clipping. It could open the way to other transgastric abdominal organ removals.

Pueraria tuberosa DC (Family: Fabaceae) is a reputed medicinal herb of Indian traditional system of medicines distributed throughout tropical parts of the India.[1] In India it has several vernacular names like in Bengali: shimia, batraji, Gujarati: vidarikand; Hindi: bilaikand; Kannada: gumadi gida; Malayalam: mutukku; Marathi: badra; Tamil and Telugu: dari gummadi.[2] Traditionally, the P. tuberosa tubers (PTT) are used as tonic, anti-rheumatic, diuretic, galactogogue, vital energy and immune booster.[1,3] PTT was reported to contain puerarin, daidzein, puerarone, coumestan, tuberosin, pterocarpintuberosin, puetuberosanol and hydroxytuberosone.[4] The isoflavone, puerarin [Figure 1], one of the most active constituent of PTT, revealed wide range of pharmacological activities including hypoglycemic,[5] anti-cancer,[6] cardioprotective,[7] neuroprotective,[8] anti-allergic,[9] and anti-arrhythmic[10] activity. Figure 1 Chemical structure of puerarin The quantitative determination of bioactive metabolites in the extracts and formulations is essential for quality control Batimastat and dose determination of herbal medicines.

The diversity of cellulosomal structural proteins is very similar

The diversity of cellulosomal structural proteins is very similar to what is found in Clostridium thermocellum and other cellulosomal microorganisms. However, chronic myelocytic leukemia CBM2 modules are not very common in cellulolytic clostridia, with C. phytofermentans and C. cellulovorans each having one such domain. C. clariflavum has four of these domains and they are associated with three separate multi-cohesin (Type I) domains with no anchoring mechanism. It may also be noted that the organization of the scaffoldin and anchoring proteins resembles the cellulosomal complexes found in the mesophile Acetivibrio cellulolyticus [42,43] more than it does the C. thermocellum cellulosome. Pyruvate metabolism The genome sequence of C. clariflavum revealed that this organism possesses a standard glycolytic pathway.

However, the pyruvate node is slightly different from other Cluster III clostridia in that C. clariflavum possesses genes for both pyruvate kinase (Clocl_1090) and pyruvate dikinase (PPDK, Clocl_2755). This may be of relevance to pyruvate metabolism because genomes of cellulolytic clostridia from cluster III reveal that the pathway from phosphoenol pyruvate (PEP) to pyruvate in these organisms uses either PPDK (Clostridium thermocellum ATCC 27405 and DSM 1313) or pyruvate kinase (C. cellulolyticum, C. papyrosolvens). There are nevertheless cellulolytic clostridia outside of Cluster III that also possess both, as is the case of Clostridium cellulovorans. Hemicellulose sugars metabolism C. clariflavum possesses a variety of xylanolytic enzymes that allow it to break down xylan completely to xylose, unlike C.

thermocellum, which is only able to break xylan down to xylooligomers. One of the key enzymes in xylose utilization, xylose isomerase, is found in mesophilic xylanolytic/cellulolytic clostridia such as C. cellulolyticum, C. phytofermentans, C. papyrosolvens and C. cellulovorans, as well as in hyperthermophiles like Caldicellulosiruptor bescii. However, the genome of C. clariflavum does not seem to possess a xylose isomerase. On the other hand, a putative xylulose kinase has been identified in C. clariflavum (Clocl_2440), which is a key difference from C. thermocellum, where this enzyme is absent. Xylulose kinase is usually adjacent to or in the same operon as xylose isomerase. A xylose epimerase (5.1.3.

4) that leads to the production of L-ribulose-5P is immediately adjacent (Clocl_2439) to the putative xylulose kinase. In C. clariflavum, these genes are also surrounded by a variety of hemicellulose-active enzymes in an operon from Clocl_2435 to Clocl_2447, that includes 3 family Carfilzomib 10 glycosyl hydrolases. Considering that none of these enzymes is present in C. thermocellum, there should be great interest in further exploring this operon in C. clariflavum and in environmental isolates. An alternative xylose epimerase (5.1.3.

The excitement to develop new techniques has given rise to natura

The excitement to develop new techniques has given rise to natural orifice transluminal endoscopic surgery (NOTES) [8�C10]. This procedure in both animal [11] and human [12] models has shown some success but scientific assay certainly has technical challenges: using transgastric, transvaginal, and transrectal access to the abdominal viscera and the need for expensive specialized equipment has hindered the widespread acceptance of this approach. Therefore use of the NOTES approach in performing routine colon resection is far from being practical at this time. Single-incision laparoscopic surgery (SILS) has advantages over NOTES in that existing laparoscopic instruments can be used and relatively minor adjustments from the current multiport laparoscopic technique are needed.

The initial applications of SILS in gastrointestinal surgery were cholecystectomy [13], appendectomy [14] and recently, this technique has also been applied to colorectal surgery [15�C18]. In comparison to multiport laparoscopic colectomy, the potential advantages of SILS are thought to be improved cosmesis as well as incisional and/or parietal pain and avoidance of port site-related complications [40]. Since 2008 when single-incision laparoscopic colectomy (SILC) was first introduced, the number of relevant publications has been increasing year by year as shown in Figure 1. However, because of still limited number of studies reporting SILC [41], its clinical significance remains to be elucidated. The aim of this study is to analyze current literature on SILC and access its potential benefits or efficacy as well as its feasibility and safety.

Figure 1 The number of publications regarding single-incision laparoscopic colectomy. 2. Materials and Methods 2.1. Literature Search Strategies A systematic search of the scientific literature was carried out using the MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (Available at:, National Research Register, The York (UK) Centre for Reviews, American College of Physicians (ACP) Journal Club, Australian Clinical Trials Registry, relevant online journals, and the Internet for the years 1983�CAugust 2011 to obtain access to all relevant publications, especially randomized controlled trials, systematic reviews, and meta-analyses involving SILC.

The search terms were ��single-incision,�� ��single port,�� ��single access,�� ��single site,�� ��laparoscopic colectomy,�� ��colectomy,�� and ��laparoscopic colorectal surgery.�� 2.2. Inclusion and Exclusion Criteria Articles were selected if the abstract contained data on patients who underwent SILC for colorectal diseases in the form of RCTs Entinostat and other controlled or comparative studies. Conference abstracts were included if they contained relevant data. The reference lists of these articles were also reviewed to find additional candidate studies. Searches were conducted without language restriction.

In accordance with the known ability of L methylohalidivorans DS

In accordance with the known ability of L. methylohalidivorans DSM 14336T to selleck inhibitor grow by oxidation of methyl halides [1], the genome analysis revealed the genes for the proposed pathway of methyl chloride metabolism as described by McDonald et al. 2002 [9]. Using the JGI-IMG BLASTp tool [51,52], the gene for first methyltransferase I (cmuA) indeed yielded a hit to the gene cmuA (��predicted cobalamin binding protein��, Meth_2531) in the genome of L. methylohalidivorans DSM 14336T, with a sequence similarity of 31%. Searching for the second enzyme methyltransferase II (cmuB) yielded a hit to the enzyme adjacent to the predicted cobalamin binding protein (��methionine synthase I (cobalamin-dependent), methyltransferase domain��, Meth_2528).

For the next enzymes in the methyl-chloride metabolism, we compared the genes metF, folD, purU and FDH and found the following results: 39% similarity to a 5,10-methylenetetrahydrofolate reductase (Meth_1763), for metF; 56% to a 5,10-methylene-tetrahydrofolate dehydrogenase/Methenyl-tetrahydrofolate cyclohydrolase (Meth_4077, Meth_3180) for folD; 36% to a phosphoribosylglycinamide formyltransferase, formyltetrahydrofolate-dependent (Meth_2536) for purU; and 79% to a formate dehydrogenase (Meth_4011) for FDH. An estimate of the DNA-DNA hybridization (DDH) similarity between L. methylohalidivorans DSM 14336T and the draft genomes of L. aquimarina DSM 24565T, L. nanhaiensis DSM 24252T, P. arcticus DSM 23566T, P. caeruleus DSM 24564T, P. daeponensis DSM 23529T, P. gallaeciensis CIP 105210T and P.

inhibens DSM 16374T was generated with the GGDC Genome-to-Genome Distance Calculator version 2.0 [53-55]. This system calculates the distances by comparing the genomes to obtain HSPs (high-scoring segment pairs) and interfering distances from three formulae (1, HSP length / total length; 2, identities / HSP length; 3, identities / total length) [54]. Table 7 shows the results of the pairwise comparisons between L. methylohalidivorans DSM 14336T and the other seven genomes. As the results of the 16S rRNA analysis (Figure 1) revealed, the two Leisingera species L. methylohalidivorans and L. aquimarina show a close relationship, whereas L. nanhaiensis does not cluster together with the other two Leisingera species. The DDH similarities calculated in silico yielded similar results, indicating that the classification of L.

nanhaiensis might need to be reconsidered. Furthermore, the DDH similarities of L. methylohalidivorans to Phaeobacter species are not significantly smaller, especially in the case Entinostat of P. caeruleus and P. daeponensis, than to L. aquimarina and as already described to L. nanhaiensis.

This effect of host sex, recorded even in humans, has mainly been

This effect of host sex, recorded even in humans, has mainly been attributed to sex-specific differences in immune response, hormones, and resource allocation Tofacitinib Citrate side effects [1],[6]�C[11]. For example, the male hormone negatively affects the efficiency of the immune system. Other sex-dependent characteristics, however, including morphological, physiological, behavioral, dietary, and life history traits, may also contribute to these observations. Parasite populations are expected to have adapted to the characteristics of their most common host type [12]. If a parasite population evolves mainly in one sex (e.g., those transmitted among extremely sex-biased host populations), sex-specific characteristics may impact how the parasite adapts to that host (Table 1).

Therefore, without considering the sex of the host in which the parasite primarily evolved, it is difficult to disentangle whether sex-biased parasitism is the result of differences among hosts only, or if adaptation of parasites contributed to these characteristics as well. Table 1 Examples of sexually dimorphic traits that might influence parasite evolution. Here, we argue that the sex of the host can impose selection on the parasite itself, which in turn will contribute to variation in disease prevalence and expression among male and female hosts. This hypothesis could be tested in systems where hosts and parasites can be used in experimental infections and where parasite isolates can be obtained from both host sexes.

But, to our knowledge, such experiments have never been done, probably because it is assumed that the prevalence and severity of disease found in different host sexes are caused by the characteristics of the host alone. We propose that parasite adaptation to specific host sexes can lead to three different evolutionary outcomes for the parasite: 1) parasites that adapt differently to each sex, leading to dimorphism in the parasite population, here called ��host sex�Cspecific dimorphism��, 2) parasites that specialize on only one sex: ��single sex specialization��, and 3) parasites with phenotypically plastic traits, whose expression is dependent on the sex of their host: ��plastic sex-specific disease expression��. We will begin by explaining in more detail these three evolutionary scenarios using a simple experimental design to help distinguish them (Box 1, Figure 1).

Batimastat The conditions under which these scenarios may evolve differ strongly. We also attempt to pinpoint those conditions that are likely to play a crucial role for the evolution of sex-specific parasite adaptation and lead either to monomorphic parasite populations or to dimorphic parasite populations (Figure 2). Then, we discuss how host demographic properties, notably host sex ratio and social structure, can influence the extent to which the parasite evolves.

After two days incubation at 37��C/5% CO2, 1 ��Ci of 3HTdR (5′-3H

After two days incubation at 37��C/5% CO2, 1 ��Ci of 3HTdR (5′-3H Thymidine spec.act 14.4 Ci/mmol, Amersham Biosciences) was added. After an additional 16�C18 hr of metabolic labelling, the cells were harvested on GF/C filters (Inotech AG, Basle, Switzerland) and analysed for incorporated radioactivity using a liquid scintillation counter (TriCarb 2500 TR, Packard Instruments, Meriden, CT). Spleen cells obtained from four mice immunised with the plasmid vector without insert constituted the negative control. The stimulation index (SI) was calculated as the ratio of radioactivity incorporated into cells from vaccinated mice and the count rate in cells from control mice.

Plaque reduction neutralisation test (PRNT) Heat-inactivated mouse sera including positive and negative controls, were serially diluted three-fold in PBS and incubated with a virus suspension containing about 30 plaque forming units (PFU) of RVFV. The mixtures were incubated for 90 min at 37��C and thereafter used to infect monolayers of BHK-21 cells in 6-well tissue culture plates (NUNC tissue culture, Nalgene Nunc International). After an adsorption period of 30 min at 37��C, the cells were rinsed with PBS and incubated with cell culture media containing 1% Carboxy-Methyl Cellulose (Aquacide II, Calbiochem?, Merck, CA) for six days at 37��C/5%CO2. The cells were subsequently fixed with 10% formaldehyde, washed with water and counter-stained with 1% crystal violet in water containing 20% ethanol and 0.7% NaCl. The PRNT50 titer was calculated as the reciprocal of the highest serum dilution that reduced the number of plaques by 50%, as compared to the virus control.

Statistical methods The outcome of the challenge was evaluated using the Fisher exact test (Epi Info?, Version 3.5). Quantitative variables were based on measurements of at least two independent experiments containing duplicate samples. Variables are expressed as means and the error bars represent the standard deviation. Results Antibody response after immunisation with cDNA encoding the N protein Genetic vaccination with cDNA encoding the N protein resulted in a strong humoral immune response in all mice. Anti-N specific antibodies (total Ig) were detected by ELISA already after the first immunisation and were followed by a large increase in titers after additional vaccination rounds (Fig (Fig1).1).

However, despite the strong antibody response observed after genetic vaccination with cDNA encoding the N protein, RVFV neutralising GSK-3 antibodies were not detected by PRNT (data not shown). Figure 1 Anti-N specific antibody responses (total Ig) after gene-gun vaccination with cDNA encoding the RVFV N protein. The curves correspond to the mean titers in individual mouse sera measured by ELISA. The error bars represent the standard deviation between …

The demographic, anthropometric, and laboratory characteristics o

The demographic, anthropometric, and laboratory characteristics of the subgroup cases were not significantly different from those of the cancer cases. Table 2. Anthropometric and laboratory characteristics of study subjects Mean serum hs-CRP selleck catalog level was significantly higher in subjects with metabolic syndrome (1.9 mg/L) than in those without metabolic syndrome (1.3 mg/L; P < 0.01, Wilcoxon rank-sum test). We also analyzed the association between hs-CRP and cancer according to the metabolic syndrome. The results are shown in Table Table3.3. After stratification, the positive associations persisted in subjects without metabolic syndrome. The adjusted ORs (model III) for cancer in subjects with metabolic syndrome were 1.51 (95% CI = 1.05�C2.17) in the second highest hs-CRP category and 2.

19 (95% CI =1.38�C3.45) in the highest hs-CRP category, as compared with the lowest category (P for trend = 0.0006). The adjusted ORs (model III) for cancer in subjects without metabolic syndrome were 1.04 (95% CI = 0.81�C1.34) in the second highest hs-CRP category and 1.92 (95% CI = 1.41�C2.63) in the highest hs-CRP category, as compared with the lowest category (P for trend = 0.0009). Table 3. Odds ratios (ORs) and 95% confidence intervals for cancer by serum hs-CRP category and metabolic syndrome status Overall, the prevalence ORs for cancer were positively associated with increasing categories of hs-CRP (<1, 1�C3, >3 mg/L). Crude and adjusted ORs for cancer are presented in Table Table4.4. The crude ORs for cancer were 1.36 (95% CI = 1.16�C1.62) for the second highest hs-CRP category and 2.

49 (95% CI = 2.02�C3.07) for the highest hs-CRP category, as compared with the lowest hs-CRP category (P for trend <0.0001). After adjustment for age, sex, BMI, abdominal obesity, diabetes, hypertension, dyslipidemia, aspirin use, smoking, alcohol consumption, exercise, education level, and income, the positive associations were weaker, but remained. The adjusted ORs for cancer were 1.16 (95% CI = 0.95�C1.42) for the second highest hs-CRP category and 1.94 (95% CI = 1.50�C2.50) for the highest hs-CRP category, as compared with the lowest hs-CRP category (P for trend <0.0001). The association was not attenuated after excluding cancer cases detected within 1 year of the health examination. These results are presented in Table Table44. Table 4.

Odds ratios (ORs) and 95% confidence intervals for cancer by serum hs-CRP category Subjects were stratified according to sex to assess the sex-specific association of hs-CRP and cancer. After stratification, as compared with the lowest hs-CRP category, the positive associations were stronger for women than for men in the second highest hs-CRP category and for men as compared with women in the highest hs-CRP category. The adjusted ORs (model III) for cancer in men were 1.15 (95% CI =0.90�C1.48) Entinostat in the second highest hs-CRP category and 2.15 (95% CI = 1.60�C2.

Approximately 27% of Americans use nicotine regularly, with approximately 24% meeting Diagnostics and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) criteria for nicotine dependence at some point in their lives (Breslau, Johnson, Hiripi, & Kessler, 2001). Decades of twin and family studies have demonstrated consistently that approximately 50% of total vulnerability to nicotine dependence results from heritable factors (True et al., 1999; Tsuang, Bar, Harley, & Lyons, 2001). Since smoking results in 400,000 deaths and $157 billion in economic expenditures annually in the United States, the identification of the genetic architecture that initiates and maintains nicotine dependence is a high public health priority (Centers for Disease Control and Prevention, 2002).

In response to this challenge, a large number of genetic studies have attempted to identify gene loci containing variability that affects vulnerability to nicotine dependence. Before 2005, these reports consisted largely of candidate gene and linkage analyses (Li, 2006). Many of these studies were pivotal in advancing our understanding of the role of genetic variation in critical gene pathways, such as the cholinergic neurotransmission system, in altering vulnerability to nicotine dependence. However, these linkage and candidate gene studies were limited by either sample size or scale of genotyping. In an attempt to transcend these problems, the National Institute on Drug Abuse funded a pair of large-scale association studies by a group of investigators in collaboration with Perlegen Sciences (Mountain View, CA) referred to as the Collaborative Study of the Genetics of Nicotine Dependence (NICSNP) consortium.

This consortium first performed a high-density association case�Ccontrol analysis of 482 nicotine dependence Cilengitide cases and 466 controls using a 2.4 million single nucleotide polymorphism (SNP) platform and a DNA pooling technique (Bierut et al., 2007). This was then followed by individual genotyping of the 39,213 SNPs showing the strongest evidence of association in a sample of 1,050 cases and 879 controls.

All the daily smokers participating in the program were invited t

All the daily smokers participating in the program were invited to participate. Participants reported attaining the following levels of education: 40.7% completed high school, 30.9% completed college (community college or technical schooling), 13.0% completed university (traditional 4-year schooling), 10.6% completed junior high school, 4.1% completed elementary any other enquiries school, and 0.8% did not report educational status. With regard to marital/relationship status, 48.0% of the sample reported being married/cohabiting with a partner, 35.0% reported being separated/divorced/widowed, and 17.1% reported being single. Participants reported smoking an average of 19.71 cigarettes/day (SD=7.57) and endorsed relatively high levels of nicotine dependence (M=6.25, SD=2.

17), as indexed by the Fagerstr?m Test for Nicotine Dependence (FTND; Fagerstr?m, 1978; Heatherton, Kozlowski, Frecker, & Fagerstr?m, 1991) at treatment outset. Participants reported initiating daily smoking at a mean age of 16.60 years (SD=4.77) and smoking regularly for an average of 28.28 years (SD=10.64). In terms of smoking cessation, participants endorsed an average of 2.95 (SD=2.85) ��serious�� lifetime quit attempts and 5.77 (SD=12.57) lifetime quit attempts lasting longer than 12 hr. The longest average lifetime period of smoking abstinence after a quit attempt among participants was 1.14 years (SD=2.74). Participants had the option of using nicotine replacement therapy (NRT) during the study (see Measures and Procedure), and all accepted the optional NRT.

Data regarding NRT use are reported here for only those participants with smoking calendar log data at or following the quit day appointment (n=106) as only these participants are included in the analyses (see Results). Upon enrollment in the study (approximately 2 weeks prior to quit day), 8 participants requested only nicotine gum, 6 participants requested only the nicotine patch, 90 participants requested the nicotine gum and patch, 1 participant did not request NRT during the first week (but at week 2 of the study, this participant requested both nicotine gum and patch), and 1 participant’s NRT data were missing for the first week (but at week 2 of the study, this participant requested both nicotine gum and patch). Participants�� NRT regimens were modified throughout the study, as based on individual requests or expressed need.

Measures Descriptive baseline measures. Participants provided demographic and background information such as age, gender, marital status, educational attainment, and annual income during the first session. At this time, participants also were asked to indicate if they were accepting the NRT provided, and whether they were accepting the gum, the patch, or both. All participants were Cilengitide offered at least one form of NRT as part of the treatment research program. Smoking History Questionnaire.
