Clostridium acetobutylicum is not able to grow on glycerol as the sole carbon source since it cannot reoxidize the excess of NADH generated by glycerol catabolism. Nevertheless, when the pSPD5 plasmid, carrying the NADH-consuming 1,3-propanediol pathway from C. butyricum VPI 3266, was introduced into C. acetobutylicum DG1, growth on glycerol was achieved, and 1,3-propanediol was produced. In or...

Eubacterium sp. strain VPI 12708 has several bile acid-inducible (bai) genes which encode enzymes in the bile acid 7 alpha-dehydroxylation (7 alpha DeOH) pathway. Twelve 7 alpha DeOH-positive intestinal bacterial strains were assayed for 7 alpha DeOH activity, and 13 strains were tested for hybridization with bai genes. Cholic acid 7 alpha DeOH activity varied greatly (> 100-fold) among these s...

Mitochondrial ATP production is vital for meeting cellular energy demand at rest and during periods of high ATP turnover. We hypothesized that high-intensity interval training (HIT) would increase ATP flux in resting muscle (VPi→ATP) in response to a single bout of exercise, whereas changes in the capacity for oxidative ATP production (Vmax) would require repeated bouts. Eight untrained men (27...

Epidemic Vibrio cholerae possess the VPI (Vibrio pathogenicity island) essential virulence gene cluster. The VPI is 41.2 kb in size and encodes 29 potential proteins, several of which have no known function. We show that the VPI-encoded Orf4 is a predicted 34-kDa periplasmic protein containing a zinc metalloprotease motif. V. cholerae seventh-pandemic (El Tor) strain N16961 carrying an orf4 mut...

A linked cell-free system has been developed which is capable of transcribing and translating mamalian viral DNA, and its characteristics and requirements are outlined. In this system, simian virus 40 (SV40) DNA Form I (supercoiled) directed the synthesis of discrete polypeptides up to 85,000 daltons in size. One of these products was indistingusihable from authentic major virus capsid protein ...

OBJECTIVE Velopharyngeal insufficiency (VPI) is a common complication after cleft palate repair, it may be due to lack of levator sling reconstruction and/or palatal shortening. Furlow palatoplasty has the advantages of retro-positioning of levator palati muscles and palatal lengthening. The aim of this study was to assess the efficacy of Furlow palatoplasty in the treatment of VPI in patients ...

PURPOSE To compare the nasoendoscopic findings related to the velopharyngeal gap among patients with cleft palate who underwent the Furlow (F) technique and those who underwent the von Langenbeck (vL) technique for primary palatal surgery, who remained with velopharyngeal insufficiency (VPI). METHODS The analyzed data were retrieved from the institution's data of recordings of nasoendoscopic ...

Machine learning is an important part of the data science field. In petrophysics, machine algorithms and applications have been widely approached. this context, Vietnam Petroleum Institute (VPI) has researched deployed several effective prediction models, namely missing log prediction, fracture zone density forecast, etc. As one our solutions, VPI-MLogs a web-based deployment platform which int...

OBJECTIVES Understanding the clinicopathological features of patients with skip N2 metastases (SN2) in clinical early stage lung cancer is important for surgical planning and other treatment considerations; however, the factors associated with SN2 are unclear. This study aimed to investigate the clinicopathological features associated with SN2 in patients with clinical stage IA (cIA) non-small-...

Abstract Degenerate minima in momentum space—valleys—provide an additional degree of freedom that can be used for information transport and storage. Notably, such naturally exist the band structure transition metal dichalcogenides (TMDs). When these atomically thin crystals interact with intense laser light, second harmonic generated (SHG) field inherits special characteristics reflect not only...
