Hotel W Barcelona: style department (housekeeping)

Este relatório pretende descrever a experiência proporcionada pelo estágio efetuado no departamento de Style do hotel W Barcelona, enquanto supervisor de housekeeping. Para melhor conseguir definir esta experiência, é feita uma caraterização da entidade de acolhimento, referindo os elementos diferenciadores associados à brand do hotel, assim como aspetos gerais da cadeia hoteleira a que esta está liga. Segue-se uma revisão de literatura onde é explorada a descrição do departamento de alojamento e do subdepartamento de housekeeping. Nesta revisão focam-se as funções dos vários colaboradores pertencentes ao subdepartamento, assim como os variados documentos inerentes ao decorrer da operação. Posteriormente é feita uma descrição da realidade do hotel, ao nível da área de housekeeping: relata-se as funções dos vários elementos do departamento, dando-se especial destaque à função de supervisor de andares. Refere-se quais os procedimentos e relatórios exigidos, durante a operativa do hotel. Comenta-se, também, a implementação de um sistema (REX), que visa melhorar o desempenho deste departamento. Comparando os conceitos obtidos através da revisão da literatura com a realidade do hotel verifica-se que não é fácil implementar grandes inovações, dentro da área do housekeeping, e que a forma de operar não conheceu profundas alterações nos últimos dez anos e conclui-se que este hotel estabeleceu para a operativa, procedimentos estandardizados.

A retrospective model of oocyte competence: global mRNA and housekeeping transcripts are not associated with in vitro developmental outcome

Oocyte developmental competence depends on maternal stores that support development throughout a transcriptionally silent period during early embryogenesis. Previous attempts to investigate transcripts associated with oocyte competence have relied on prospective models, which are mostly based on morphological. criteria. Using a retrospective model, we quantitatively compared mRNA among oocytes with different embryo development competence. A cytoplasm biopsy was removed from in vitro matured oocytes to perform comparative analysis of amounts of global polyadenylated (polyA) mRNA and housekeeping gene transcripts. After parthenogenetic activation of biopsied oocytes, presumptive zygotes were cultured individually in vitro and oocytes were classified according to embryo development: (i) blocked before the 8-cell stage; (ii) blocked between the 8-cell and morulae stages; or (iii) developed to the blastocyst stage. Sham-manipulated controls confirmed that biopsies did not alter development outcome. Total polyA mRNA amounts correlate with oocyte diameter but not with the ability to develop to the 8-cell and blastocyst stages. The last was also confirmed by relative quantification of GAPDH, H2A and Hprt1 transcripts. In conclusion, we describe a novel retrospective model to identify putative markers of development competence in single oocytes and demonstrate that global mRNA amounts at the metaphase II stage do not correlate with embryo development in vitro.

Effect of creatine supplementation on housekeeping genes in human skeletal muscle using real-time RT-PCR

The present study examined the validity and reliability of measuring the expression of various genes in human skeletal muscle using quantitative real-time RT-PCR on a GeneAmp 5700 sequence detection system with SYBR Green 1 chemistry. In addition, the validity of using some of these genes as endogenous controls (i.e., housekeeping genes) when human skeletal muscle was exposed to elevated total creatine levels and exercise was also examined. For all except 28S, linear relationships between the logarithm of the starting RNA concentrations and the cycle threshold (C_T) values were established for ß-actin, ß2-microglobulin (ß₂M), cyclophilin (CYC), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH). We found a linear response between C_T values and the logarithm of a given amount of starting cDNA for all the genes tested. The overall intra-assay coefficient of variance for these genes was 1.3% and 21% for raw C_T values and the linear value of 2^-C_T, respectively. Interassay variability was 2.3% for raw C_T values and 34% for the linear value of 2^-C_T. We also examined the expression of various housekeeping genes in human skeletal muscle at days 0, 1, and 5 following oral supplementation with either creatine or a placebo employing a double-blind crossover study design. Treatments were separated by a 5-wk washout period. Immediately following each muscle sampling, subjects performed two 30-s all-out bouts on a cycle ergometer. Creatine supplementation increased (P < 0.05) muscle total creatine content above placebo levels; however, there were no changes (P > 0.05) in C_T values across the supplementation periods for any of the genes. Nevertheless, 95% confidence intervals showed that GAPDH was variable, whereas ß-actin, ß₂M, and CYC were the least varying genes. Normalization of the data to these housekeeping genes revealed variable behavior for ß₂M with more stable expressions for both ß-actin and CYC. We conclude that, using real-time RT-PCR, ß-actin or CYC may be used as housekeeping genes to study gene expression in human muscle in experiments employing short-term creatine supplementation combined with high-intensity exercise.

Real time RT-PCR analysis of housekeeping genes in human skeletal muscle following acute exercise

Studies examining gene expression with RT-PCR typically normalize their mRNA data to a constitutively expressed housekeeping gene. The validity of a particular housekeeping gene must be determined for each experimental intervention. We examined the expression of various housekeeping genes following an acute bout of endurance (END) or resistance (RES) exercise. Twenty-four healthy subjects performed either a interval-type cycle ergometry workout to exhaustion (~75 min; END) or 300 single-leg eccentric contractions (RES). Muscle biopsies were taken before exercise and 3 h and 48 h following exercise. Real-time RT-PCR was performed on ß-actin, cyclophilin (CYC), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and ß2-microglobulin (ß2M). In a second study, 10 healthy subjects performed 90 min of cycle ergometry at ~65% of O2 max, and we examined a fifth housekeeping gene, 28S rRNA, and reexamined ß2M, from muscle biopsy samples taken immediately postexercise. We showed that CYC increased 48 h following both END and RES exercise (3- and 5-fold, respectively; P < 0.01), and 28S rRNA increased immediately following END exercise (2-fold; P = 0.02). ß-Actin trended toward an increase following END exercise (1.85-fold collapsed across time; P = 0.13), and GAPDH trended toward a small yet robust increase at 3 h following RES exercise (1.4-fold; P = 0.067). In contrast, ß2M was not altered at any time point postexercise. We conclude that ß2M and ß-actin are the most stably expressed housekeeping genes in skeletal muscle following RES exercise, whereas ß2M and GAPDH are the most stably expressed following END exercise.

Comparative phylogenies of the housekeeping genes atpD, infB and rpoB and the 16S rRNA gene within the Pasteurellaceae

Phylogenies of housekeeping gene and 16S rRNA gene sequences were compared to improve the classification of the bacterial family Pasteurellaceae and knowledge of the evolutionary relationships of its members. Deduced partial protein sequences of the housekeeping genes atpD, infB and rpoB were compared in 28, 36 and 28 representative taxa of the Pasteurellaceae, respectively. The monophyly of representatives of the genus Gallibacterium was recognized by analysis of all housekeeping genes, while members of Mannheimia, Actinobacillus sensu stricto and the core group of Pasteurella sensu stricto formed monophyletic groups with two out of three housekeeping genes. Representatives of Mannheimia, Actinobacillus sensu stricto, [Haemophilus] ducreyi and [Pasteurella] trehalosi formed a monophyletic unit by analysis of all three housekeeping genes, which was in contrast to the 16S rRNA gene-derived phylogeny, where these taxa occurred at separate positions in the phylogenetic tree. Representatives of the Rodent, Avian and Aphrophilus-Haemophilus 16S rRNA gene groups were weakly supported by phylogenetic analysis of housekeeping genes. Phylogenies derived by comparison of the housekeeping genes diverged significantly from the 16S rRNA gene-derived phylogeny as evaluated by the likelihood ratio test. A low degree of congruence was also observed between the individual housekeeping gene-derived phylogenies. Estimates on speciation derived from 16S rRNA and housekeeping gene sequence comparisons resulted in quite different evolutionary scenarios for members of the Pasteurellaceae. The phylogeny based on the housekeeping genes supported observed host associations between Mannheimia, Actinobacillus sensu stricto and [Pasteurella] trehalosi and animals with paired hooves.

Investigating the pathogenicity of mutations in two ubiquitously expressed housekeeping genes that cause autosomal dominant retinitis pigmentosa

The purpose of this dissertation research was to investigate potential mechanisms through which mutations in two ubiquitously expressed genes, inosine monophosphate dehydrogenase 1 (IMPDH1) and pre-mRNA processing factor 31 (PRPF31), cause autosomal dominant retinitis pigmentosa (adRP) but have no other apparent clinical consequences. Basic properties of the gene and gene product, such as expression and protein levels, were examined. The purpose of our research is to understand the genetic basis of inherited retinopathies such as retinitis pigmentosa (RP). RP is a heterogeneous retinal dystrophy that affects approximately one in 3,700 individuals, making it the most common heritable retinal degenerative disease worldwide. Currently, mutations in 35 genes are known to cause RP and additional loci have been mapped but the underlying gene is not yet known. Often the genes associated with RP are integral to the biological processes underlying vision, making their role in retinal disease easy to explain. However, the mechanisms by which other genes cause RP are not apparent, especially widely-expressed genes. For IMPDH1, this research characterized the enzymatic properties of retinal isoforms. Results show that the retinal isoforms have enzymatic functions similar to the previously known canonical IMPDH1 whether or not an adRP pigmentosa mutation is included in the protein. For PRPF31, this research tested the hypothesis that functional haploinsufficiency is the cause of disease and relates to nonpenetrance in some individuals. Studies in patients with known mutations show that haploinsufficiency is the likely cause of disease, however, we did not confirm that non-penetrant individuals are protected from disease via increased expression of the wild type allele. Information gleaned from these functional studies, and the testing methods developed in tandem, will contribute to future research on disease mechanism related to adRP. ^

Cysteine-proteases and cystatins from barley: molecular and functional characterization in housekeeping and defense processes

Plant cysteine-proteases (CysProt) represent a well-characterized type of proteolytic enzymes that fulfill tightly regulated physiological functions (senescence and seed germination among others) and defense roles. This article is focused on the group of papain-proteases C1A (family C1, clan CA) and their inhibitors, phytocystatins (PhyCys). In particular, the protease–inhibitor interaction and their mutual participation in specific pathways throughout the plant's life are reviewed. C1A CysProt and PhyCys have been molecularly characterized, and comparative sequence analyses have identified consensus functional motifs. A correlation can be established between the number of identified CysProt and PhyCys in angiosperms. Thus, evolutionary forces may have determined a control role of cystatins on both endogenous and pest-exogenous proteases in these species. Tagging the proteases and inhibitors with fluorescence proteins revealed common patterns of subcellular localization in the endoplasmic reticulum–Golgi network in transiently transformed onion epidermal cells. Further in vivo interactions were demonstrated by bimolecular fluorescent complementation, suggesting their participation in the same physiological processes.
