Abstract:
ABSTRACT Sirtuins are NAD+-dependent protein deacylases that are conserved in all domains of life and are involved in diverse cellular processes, including control of gene expression and central metabolism. Eukaryotic sirtuins have N-terminal extensions that have been linked to protein multimerization and cellular localization. Here the first evidence of sirtuin isoforms in bacteria is reported. The enterobacterium Salmonella enterica synthesizes two isoforms of CobB sirtuin, a shorter 236-amino-acid isoform (here CobBS) and a longer 273-amino-acid isoform (here CobBL). The N-terminal 37-amino-acid extension of CobBL is amphipathic, containing 18 basic amino acids (12 of which are Arg) and 13 hydrophobic ones; both isoforms were active in vivo and in vitro. Northern blot and transcription start site analyses revealed that cobB is primarily expressed as two monocistronic cobB mRNAs from two transcription start sites, one of which was mapped within the neighboring ycfX gene and the other of which was located within cobB. Additionally, a low-abundance ycfX-cobB bicistronic mRNA was observed which could encode up to three proteins (YcfX, CobBL, and CobBS). CobBL isoforms are common within the family Enterobacteriaceae, but species of the genus Erwinia (including the plant pathogen Erwinia amylovora) encode only the CobBL isoform. The CobBL isoform from E. amylovora restored growth of as S. enterica cobB mutant strain on low acetate.

Abstract:
AbstractThe morphology and morphometry of nematodes of six species of the family Ceramonematidae is described using light and scanning electron microscopy. In this paper, we describe two new species and redescribe two known species of Ceramonema and one new species each of Pselionema and Pterygonema. Ceramonema altogolfi sp. n. is characterised by the 0.8-1.3 mm long body, 187-247 body annules, weakly developed zygapophyses, presence of intracuticular vacuoles, sexual dimorphism in amphid shape, presence of vaginal sclerotisation, complex gubernaculum and relatively uniform anal and cloacal annules, whilst C. inguinispina sp. n. has a 0.8-1.1 mm long body, 135-191 body annules, weakly developed zygapophyses, presence of intracuticular vacuoles, sexual dimorphism in amphid shape, absence of vaginal sclerotisation, thorn-shaped precloacal projection, plate-like gubernaculum and double cloacal annule. Pselionema psednum sp. n. is distinguished by 1.4-1.7 mm long body, 251-292 body annules, weakly developed zygapophyses, absence of intracuticular vacuoles, sexual dimorphism in amphid shape and Pterygonema mexicanum sp. n. is characterised by having amphids lacking a central thorn-like projection and pharynx with a distinct posterior glandular bulb. Populations of Ceramonema rectum and Ceramonema cf. yunfengi are also described. The male cloacal region of the species examined appears to be a rich potential source of taxonomic characters that have as yet received insufficient attention for this family.

Abstract:
Sometime during World War I,Ned Cobb, an African American sharecropper better known to us by his pseudonym Nate Shaw, journeyed from the Tallapoosa County, Alabama, farm where he was sharecropping to Opelika, a small market town about 12 miles away, to buy cotton seed hulls for his mules,meal for his family, and shoes for his children. At Mr. Sadler’s general store, Cobb had a chilling encounter with one Henry Chase, a crippled white store clerk. Chase, resentful that Cobb had been served by one of the store's white female clerks, tried to provoke a fight with Cobb and then accused Cobb of threatening him with a pistol. Cobb wisely refused to be goaded, but he was arrested anyway when Chase brought his complaint to the sheriff. Cobb only escaped trouble with the law and more trouble with Chase and his gang because of the intercession of influential white merchants who knew Cobb from earlier business in town (Rosengarten 1974: 162–72).

Abstract:
Height gain after scoliosis correction is of a special interest for the patient and family. Ylikoski was the first to suggest a formula predicting height loss in untreated scoliotic patients. Stokes has recently suggested a new formula by using Cobb angle to determine height loss in idiopathic curves. We hypothesized that new additional variables to Cobb angle such as apical vertebral translation (AVT), number of instrumented segments (N), and disc heights may increase the accuracy of predicted height gain. According to our findings simple expression for height gain by simplified version of the formula is:SPΔH=0.0059X1θ1 + 2.3(1−(θ2/θ1))N, whereθ1is preoperative Cobb angle,X1is preoperative AVT,θ2is postoperative Cobb angle, andNis the number of instrumented vertebra. The purpose of this study is to analyze a new mathematical formula to predict height gain after scoliotic deformity correction.

Abstract:
In eukaryotic cells, the N-terminal amino moiety of many proteins is modified by N-acetyltransferases (NATs). This protein modification can alter the folding of the target protein; can affect binding interactions of the target protein with substrates, allosteric effectors, or other proteins; or can trigger protein degradation. In prokaryotes, only ribosomal proteins are known to be N-terminally acetylated, and the acetyltransferases responsible for this modification belong to the Rim family of proteins. Here, we report that, inSalmonella enterica, the sirtuin deacylase CobB long isoform (CobBL) is N-terminally acetylated by the YiaC protein of this bacterium. Results of in vitro acetylation assays showed that CobBLwas acetylated by YiaC; liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to confirm these results. Results of in vitro and in vivo experiments showed that CobBLdeacetylase activity was negatively affected when YiaC acetylated its N terminus. We report 1) modulation of a bacterial sirtuin deacylase activity by acetylation, 2) that the Gcn5-related YiaC protein is the acetyltransferase that modifies CobBL, and 3) that YiaC is an NAT. Based on our data, we propose the name of NatA (N-acyltransferase A) in lieu of YiaC to reflect the function of the enzyme.

Journal of Bacteriology 180, no. 24 (December 15, 1998): 6511–18. http://dx.doi.org/10.1128/jb.180.24.6511-6518.1998.

Full text
Abstract:
ABSTRACT Expression of the prpBCDE operon of Salmonella typhimurium LT2 required (i) the synthesis of propionyl-coenzyme A (CoA) by the PrpE protein or the acetyl-CoA-synthesizing systems of the cell and (ii) the synthesis of 2-methylcitrate from propionyl-CoA and oxaloacetate by the PrpC protein. We propose that either 2-methylcitrate or a derivative of it signals the presence of propionate in the environment. This as yet unidentified signal is thought to serve as a coregulator of the activity of PrpR, the member of the sigma-54 family of transcriptional activators needed for activation of prpBCDE transcription. The CobB protein was also required for expression of the prpBCDE operon, but its role is less well understood. Expression of the prpBCDEoperon in cobB mutants was restored to wild-type levels upon induction of the propanediol utilization (pdu) operon by 1,2-propanediol. This effect did not require catabolism of 1,2-propanediol, suggesting that a Pdu protein, not a catabolite of 1,2-propanediol, was responsible for the observed effect. We explain the existence of these redundant functions in terms of metabolic pathway integration. In an environment with 1,2-propanediol as the sole carbon and energy source, expression of the prpBCDE operon is ensured by the Pdu protein that has CobB-like activity. Since synthesis of this Pdu protein depends on the availability of 1,2-propanediol, the cell solves the problem faced in an environment devoid of 1,2-propanediol where propionate is the sole carbon and energy source by having cobB located outside of thepdu operon and its expression independent of 1,2-propanediol. At present, it is unclear how the CobB and Pdu proteins affect prpBCDE expression.

Abstract:
This paper examines the productivity of hired and family labour and determinants of technical inefficiency of fish farms in Ghana. A modified Cobb-Douglas stochastic frontier production function which accounts for zero usage of family and hired labour is employed on cross-sectional data of 150 farmers collected in 2007. The results reveal that family labour, hired labour, feed, seed, land, other costs and extension visit have a reasserting influence on fish farm production. Findings also show that family and hired labour used for fish farming production in Ghana may be equally productive. The combined effects of operational and farm specific factors (age, experience, land, gender, pond type and education) influence technical inefficiency although individual effects of some variables may not be significant. Mean technical efficiency is estimated to be 79 percent. Given the present state of technology and input level, the possibility of enhancing production can be achieved by reducing technical inefficiency by 21 percent through adoption of practices of the best fish farm.

Abstract:
We have made an extensive study of New Zealand representatives of nematodes from the family Tripylidae de Man, 1876. Based on SSU DNA sequence data and phylogenetic analysis, the genera Tripylina Brzeski, 1964 and Trischistoma Cobb, 1913 are not closely related to Tripyla Bastian, 1865, the type genus of the family Tripylidae de Man 1876. The genus Tripylina is sister to Trischistoma and Trefusia de Man, 1893 and is more closely related to Enoplida than to Triplonchida. Our phylogenetic results indicate that Tripylina should be placed in Enoplida.

Abstract:
Cobb moved to Hollywood at the invitation of Will Rogers and Hal Roach. With Cobb’s work in the film business, his writing tapered off. His involvement in the filming of Judge Priest, starring Will Rogers, renewed Cobb’s belief in himself and his career. The film received excellent newspaper coverage when it was released in the fall of 1934, owing to Rogers’s celebrity. The rest of the chapter focuses on Cobb’s work and family life in Hollywood until his wealth and health began to decline.

Abstract:
In this chapter, Ellis describes Cobb’s difficult first year in the big city. Finding a job to support his family and learning how the New York newspapers were run proved to be a daunting task. Cobb’s big breakthrough came as a reporter for the New York Sun covering the Portsmouth Peace Conference. This led to several job offers, including one from Joseph Pulitzer’s Evening World, which Cobb accepted. Over the next six years, Cobb increased his role at this leading newspaper and honed his skills as a writer. Ellis then explores the development of Cobb’s writing as he branched out to produce a variety of columns and stories. Cobb’s success as a reporter led to his rapid rise to fame as he became one of the most popular writers in New York.

In the late 1920s Cobb’s popularity declined, due to the changing times. Although he continued to add books to his repertoire, they failed to receive critical acclaim. Other elements of Cobb’s life were still satisfying, such as his wanderlust and his love of spending time with friends. The stock market crash and the Great Depression took a toll on the Cobb family’s finances. While Cobb’s writing career was slowing down, Buff had become an accomplished writer. Cobb delved into work in radio and ventures in Hollywood.

Abstract:
This chapter discusses traditional vampires that live in large cob-webbed castles or crumbling stately mansions or sometimes dabble in real estate or property development, such as in the film The Satanic Rites of Dracula in 1973. The chapter points out how vampires are generally depicted as wealthy individuals who rarely have to worry about income or housing. It also considers the Twilight movies, where the Cullen 'family' resides not in a castle or old dark house but an airy modern Frank Lloyd Wright-esque home. The chapter reviews the character Eli in Tomas Alfredson's Let the Right One In, who contents herself with a bog-standard flat on a Swedish housing estate where she customizes the bathroom to turn it into a light-tight nest. It explores Eli and Håkan's flat that bears all the hallmarks of an environment where the occupants have lost interest in the superficial trappings of life.

Abstract:
In the fall we had great fun picking our orchard apples and harvesting in the garden. There were two old apple trees, undoubtedly planted by the Baxter family in the late 1800s. One bore very large sweet apples, which probably was a Wolf River type, in Mother’s estimation, and the other bore just nice, tasty apples. The trunks of these two trees were ten to twelve inches in diameter, so they were really mature trees. Under and around these apple trees we usually had planted potatoes (our best crop!), corn, and huge beefsteak tomatoes. A slice from a beefsteak tomato warmed by the sun and just picked would cover a whole slab of bread. What fabulous sandwiches these made with mayonnaise. Makes me hungry to think about it. It was always such fun to visit our garden with Mother, as she would get very enthusiastic about our crops. Most fun was to dig potatoes. I might be at the shovel, and Mother with a bucket was collecting the potatoes, which were invariably healthy and robust. We would both get on our knees and feel around for the potatoes. Mother would get excited and ooh and ah about their size, their ruddiness, and their abundance. “Oh, Estella. Look at THAT one! Put your hands through that loose soil and make sure we did not leave any potatoes behind! Those little potatoes are hiding,” she would say, or words to that effect. Boiling these little potatoes up for supper was a special treat, as they were so tasty with butter when lightly cooked. Our corn occasionally bore enough cobs to give us a meal. We usually had good luck with onions, too. To weed this garden we had a one-wheeled cultivator with a hoe or blade attached behind the wheel, which was about one foot in diameter. The wooden handles formed a V sprouting from the axis of the wheel. With two hands one would push this wheeled implement between the rows of crops, and it would turn over the weeds, so one could keep the space between the rows pretty weed-free without too much work.
