Abstract:
In the yeast Saccharomyces cerevisiae , the paralogous genes ALT1 and ALT2 have been proposed to encode alanine aminotransferase isozymes. Although in other microorganisms this enzyme constitutes the main pathway for alanine biosynthesis, its role in S. cerevisiae had remained unclear. Results presented in this paper show that under respiratory conditions, Alt1p constitutes the sole pathway for alanine biosynthesis and catabolism, constituting the first example of an alanine aminotransferase that simultaneously carries out both functions. Conversely, under fermentative conditions, it plays a catabolic role and alanine is mainly synthesized through an alternative pathway. It can thus be concluded that ALT1 has functions in alanine biosynthesis and utilization or only alanine utilization under respiratory and fermentative conditions, respectively. ALT2 expression was repressed under all tested conditions, suggesting that Alt2p biosynthesis is strictly controlled and only allowed to express under peculiar physiological conditions.

Abstract:
A series of fluorinated free-base porphyrins (H2TPPF[Formula: see text], [Formula: see text] = 0, 8, 12, 20, 24) and the corresponding aluminum(III) porphyrin (AlTPPF[Formula: see text]-Ph, [Formula: see text] = 0, 8, 12, 20, 24) derivatives have been synthesized and their spectroscopic, redox and optical properties were investigated. The absorption studies show that the spectral shapes of investigated porphyrins are sensitive to the degree of fluorination on the meso-phenyl units. Analogously, the fluorescence quantum yields and singlet-state lifetimes depend on the number of fluorine atoms, and decrease by increasing the number of fluorine atoms. The H2TPPF[Formula: see text] and AlTPPF[Formula: see text]-Ph ([Formula: see text] = 8, 12, 20, 24) derivatives exhibited lower fluorescence intensities compared to the H2TPP and AlTPP, respectively. However, the AlTPPF[Formula: see text]-Ph ([Formula: see text] = 0, 8, 12, 20, 24) derivatives yield relatively a strong fluorescence compared to the well-known ZnTPP. As predicted, the redox potentials are shifted to the more positive side by increasing the fluorine atoms. The Lewis acidity of AlTPPF[Formula: see text]-Ph was quantified by using the absorption and fluorescence titrations with the Lewis base [Formula: see text]-methylimidazole (Me-Im). The titration data suggests that the Lewis acidity of the Al center rises when increasing the number of fluorine atoms on the porphyrin. Together, the high fluorescence quantum yields, high-potentials, unique optical and redox properties suggest that the investigated porphyrins could be potential sensitizers to mimic various components of artificial photosynthetic systems for the production of solar fuels.

Abstract:
The dye-sensitized solar cell using visible and near-infrared sensitization of nanocrystalline TiO 2 films by aluminium phthalocyanine, aluminium 2,9,16,23-tetraphenoxy-29H, 31H-phthalocyanine hydroxide (AlTPPc), was developed and its photoelectrochemical properties were investigated. The short-circuit photocurrent (ISC) was 0.026 mA cm-2, the open-circuit photovoltage ( V OC) was 186 mV, and the fill factor (FF) of solar cell using AlTPPc adsorbed on nanocrystalline TiO 2 film electrode was estimated to be 40.4%, respectively. By using AlTPPc adsorbed on nanocrystalline TiO 2 film electrode, photovoltage and photocurrent were higher compared with that of only nanocrystalline TiO 2 film electrode and were maintained under near-infrared irradiation. Thus, the solar cell using the near-infrared sensitization by AlTPPc adsorbed on nanocrystalline TiO 2 film electrode was developed.

AbstractThe chlorine functionalized dialkynylsilane (4-tBu-C6H4)(Cl)Si(C≡C-tBu)2 (3) reacted with equimolar quantities of H–AltBu2 or H–GatBu2 by hydrometallation of a C≡C triple bond and formation of mixed alkenyl-alkynylsilanes (4 and 5) in which the Si and Lewis acidic metal atoms adopt geminal positions at the α-C atoms of the alkenyl groups. Intramolecular M···Cl interactions (M=Al, Ga) afforded four-membered SiCMCl heterocycles which in comparison with 3 had significantly lengthened Si–Cl bonds. Dual hydrometallation of 3 was only observed for H–GatBu2. One Ga atom of the product (6) was coordinated by the silicon-bound Cl atom, while the second one showed an interaction with the aromatic ring of the tert-butyl-phenyl group. Treatment of the aluminium compound 4 with two equivalents of H–GatBu2 afforded a Si–H bond by Cl-H exchange and release of Cl–AltBu2. The resulting silane (7) has the Si atom and two Ga atoms bridged by the α-C atoms of two vinyl groups. The specific functionality of 4 caused a remarkable reactivity. Phenyl isocyanate reacted by the formal insertion into the Al–C(vinyl) and the activated Si–Cl bonds and resulted in the formation of a C–C bond. The product (8) has a SiC2N heterocycle with an Si–N bond and exocyclic C=C and C=O double bonds. The keto group is coordinated to a Cl–AltBu2 molecule, which was formed by the shift of the Cl atom from silicon to aluminium.

Abstract:
Anaplastic large T-cell lymphoma (ALTCL) is a rare subtype of non-Hodgkin T-cell lymphoma that occasionally occurs in the gastrointestinal tract of humans. Enteropathy-associated T-cell lymphoma (EATL) type 1 is the most common type of intestinal lymphoma in dogs, and ALTCL has not previously been reported in the intestinal tract of dogs. Thirteen dogs with intestinal masses diagnosed as intestinal lymphoma with anaplastic morphology were reviewed. Clinical data, including treatment protocols, were available for 11 cases. Immunohistochemistry for CD3, CD20, and CD30 was performed for all cases in addition to PCR for Antigen Receptor Rearrangements (PARR) for assessment of clonality. Eight (62%) of the cases presented with intestinal perforation, and all cases had 1 or more masses arising from the small intestine. Histologically, all cases were characterized by transmural infiltrates of large, CD3-positive and frequently CD30-positive cells. Neoplastic T cells had marked anisocytosis and anisokaryosis, prominent nucleoli, and occasionally indented to reniform nuclei. There was abundant necrosis and inflammation with occasional vascular invasion within neoplastic masses. All cases had a monoclonal T-cell receptor γ gene rearrangement. The median survival time was 5 days, with 1 dog surviving 2 years after the initial diagnosis. ALTCL can occur as an aggressive transmural lymphoma in the gastrointestinal tract of dogs and commonly causes intestinal perforation. ALTCL can be differentiated from EATL type 1 and might have implications for accurate prognostication and selection of therapeutic options in the future.

Abstract:
OBJECTIVE Separation surgery followed by spine stereotactic radiosurgery (SSRS) has been shown to achieve favorable rates of local tumor control and patient-reported outcomes in patients with metastatic epidural spinal cord compression (MESCC). However, rates and factors associated with adjacent-level tumor progression (ALTP) in this population have not yet been characterized. The present study aimed to identify factors associated with ALTP and examine its association with overall survival (OS) in patients receiving surgery followed by radiosurgery for MESCC. METHODS Thirty-nine patients who underwent separation surgery followed by SSRS for MESCC were identified using a prospectively collected database and were retrospectively reviewed. Radiological measurements were collected from preoperative, postoperative, and post-SSRS MRI. Statistical analysis was conducted using the Kaplan-Meier product-limit method and Cox proportional hazards test. Subgroup analysis was conducted for patients who experienced ALTP into the epidural space (ALTP-E). RESULTS The authors’ cohort included 39 patients with a median OS of 14.7 months (range 2.07–96.3 months). ALTP was observed in 16 patients (41.0%) at a mean of 6.1 ± 5.4 months postradiosurgery, of whom 4 patients (10.3%) experienced ALTP-E. Patients with ALTP had shorter OS (13.0 vs 17.1 months, p = 0.047) compared with those without ALTP. Factors associated with an increased likelihood of ALTP included the amount of bone marrow infiltrated by tumor at the index level, amount of residual epidural disease following separation surgery, and prior receipt of radiotherapy at the index level (p < 0.05). Subgroup analysis revealed that primary tumor type, amount of preoperative epidural disease, time elapsed between surgery and radiosurgery, and prior receipt of radiotherapy at the index level were significantly associated with ALTP-E (p < 0.05). CONCLUSIONS To the authors’ knowledge, this study is the first to identify possible risk factors for ALTP, and they suggest that it may be associated with shorter OS in patients receiving surgery followed by radiosurgery for MESCC. Future studies with higher power should be conducted to further characterize factors associated with ALTP in this population.

Abstract:
Приведены результаты оценки быковпроизводителей голштинской породы по молочной продуктивности и воспроизводительным качествам их дочерей. Обработаны данные 563 первотелок и 45 быковотцов. В среднем удой дочерей за 1ю лактацию от разных отцов колебался от 6784 до 7789 кг, по содержанию жира и белка в молоке различий не выявлено. Большинство производителей обладали желательной степенью реализации генетического потенциала. Основной вклад в генетическое совершенствование стада вносят быки Altahessel Sex138929389, Altajupiter Sex 66011448 и ClearEc Altar2 62916235, достоверно увеличивая удой дочерей за 305 дней 1й лактации от 350 кг до 490 кг по сравнению со средними показателями по стаду. Уровень раздоя коров по 1й лактации достоверно обусловливает их дальнейшую продуктивность. У дочерей ClearEc Altar2 отмечена положительная корреляция (0,44) между удоем и белком, а у дочерей Бодо 354239752 (r0,68) между жиром и белком. Отмечены дочери с отрицательной коррелятивной связью между удоем и жиром, это свидетельствует о том, что в этих группах с высокой молочной продуктивностью отбор коров по жирномолочности не обеспечивает повышение белковомолочности. Самый короткий сервиспериод (98 дней) характерен для дочерей Магикон 536522893, наиболее длинный у дочерей Dinom Altatyson 66133528 и Short Cut 3504510619. Используемые быкипроизводители в хозяйстве реализуют свой потенциал в более сжатые сроки, что необходимо учитывать при дальнейшем их закреплении.The results of estimation of Holstein sires based on milk productivity and reproductive qualities of their daughters are presented .The findings of 563 heifers and 45 bullsfathers were processed.on average, the milk yield of daughters for 1 lactation from different fathers ranged from 6784 to 7789 kg, theee were not found any differences in the content of fat and protein in milk.most producers had a desirable degree of realization of genetic potential. Bulls Altahessel Sex138929389, Altajupiter Sex 66011448 and ClearEc Altar2 62916235mainly contribut to the genetic improvement of the herd, significantly increasing yield of daughters in 305 days of the first lactation from 350 kg to 490 kg compared to the average for the herd. The level of milking cows on the 1st lactation reliably determines their further productivity. Daughters of ClearEc Altar2 had a positive correlation (0.44) between milk yield and protein, and daughters of Bodo bull 354239752 (r0.68) between fat and protein. Daughters with a negative correlation between milk yield and fat were noted, this indicates that the selection of cows by fat content does not provide an increase in protein content in these groups with high milk productivity. The shortest service period (98 days) are typical for daughters of Magikon 536522893, the longest the daughters Dinom Altatyson 66133528 and Short Cut 3504510619.sires, used in farming, realize their potential in a shorter time, which should be taken into account in their further consolidation.

Abstract:
Mouse CP2 is the founding member of a group of highly conserved proteins in mouse, human, chicken and Drosophila collectively referred to as the CP2 family of transcription factors. CP2 was originally identified in murine erythroleukemia (MEL) cell nuclear extracts as an activator of the mouse a-globin gene, binding a promoter element overlapping the CCAAT box. In addition Io CP2, the family includes mouse NF2d9, human LBP-1c and LBPla, homologues of mouse CP2 and NF2d9 respectively, LBP-9, chicken CPZ and Drosophila melanogaster CP2. Mammalian CP2-related proteins have generally been shown to be activators of transcription and expressed ubiquitously. There is little knowledge of factors that regulate their activity. This thesis describes CRTR-I, a novel member of the CP2 family, originally identified as a transcript differentially expressed between mouse ES and early primitive ectoderm-like (EPL) cells in vitro. In vivo expression analysis showed CRTR-I to be expressed by the pluripotent inner cell mass cells of the blastocyst, but not in the later pluripotent cells of the primitive ectoderm. Analysis during later stages of development and in the adult mouse showed CRTR-1 expression to be developmentally and spatially regulated. Greatest levels of CRTR-I expression were detected in the embryonic and adult kidneys with CRTR-I specifically expressed in the branching ureteric buds of the developing kidney with expression becoming restricted to the epithelial lining of the distal convoluted tubules during later kidney development and in the adult mouse. These sites of CRTR-I expression suggest distinct biological roles for CRTR-I function in the maintenance of pluripotency in the early stage embryo and in the development and function of the kidney. Conservation in nucleotide and amino acid sequence defined CRTR-I as a novel member of the mouse CP2 family of transcription factors. Consistent with this, CRTR-1 was shown to interact with all other members of the mouse CP2 family, forming protein complexes competent to bind a CP2 family consensus DNA response element. However, unlike other CP2 family members, CRTR-I was shown to act as a transcriptional repressor with the ability to repress transcription localised to a novel 52 amino acid N-terminal repression domain. Furthermore, the ability of CRTR-I to repress transcription was shown to be dominant over CP2 mediated transcriptional activation. CRTR-I is therefore distinct from other family members in two respects, CRTR-I expression is spatially and temporally regulated and CRTR-I acts as a dominant transcriptional repressor of CP2 family mediated transcriptional activation. This thesis also describes the identification, isolation and functional characterisation of an alternatively spliced isoform of CP2, altCP2. Similar to CRTR-1, altCP2 appears to be differentially expressed and was demonstrated to act as a dominant repressor of CP2 family mediated transcriptional activation by formation of heteromultimers with other CP2 family proteins that cannot bind DNA. Together, altCP2 and CRTR-1 provide mechanisms to achieve spatially and temporally regulated activity of ubiquitously expressed CP2 family transcriptional activators. Possible mechanisms regulating the cellular localization and transcriptional regulatory ability of CP2 family members were investigated by identification of nonrelated binding proteins. Yeast-2-hybrid analysis identified Ubc9, PIAS1 and FKBP4 as CRTR-I binding proteins. Ubc9 and PIASl function as regulators of post-translational modification by sumoylation. These have been shown to regulate the cellular localization and transcriptional regulation of other transcription factors, and were shown here to interact with other mouse CP2 family members. In contrast the immunophilin FKBP4 was determined to be a CRTR-I specific binding protein suggesting that altemate mechanisms regulate CRTR-I and other family members. Identification of CP2 family member specific binding proteins suggest mechanisms for independent regulation of CP2 family members through distinct cellular pathways. Finally, identification of the sumoylation enhancer PIAS3 and transcription factors Rexl and YYI as CRTR-I binding proteins provide further mechanisms for the regulation of CRTR-1 activity through the control of cellular localization, transcriptional regulation and promoter specificity and together suggest mechanisms for the regulation of CRTR-I activity through signaling pathways important for pluripotence and kidney development.

In this paper, a sub-1V input single-inductor dual-output (SIDO) DC-DC converter with an adaptive load-tracking control (ALTC) technology is proposed for single-cell-powered portable devices. Through the minimized number of switch and the optimum current sequence, the ALTC technique adaptively and accurately adjusts storage energy in form of inductor current according to the actual load condition without wasting surplus charge and increasing cross-regulation. Moreover, a current-mode ring oscillator with a self-bias current source (SBCS) circuit is proposed to replace the conventional startup ring oscillator to produce a nearly constant system clock. Owing to the proposed current-mode ring oscillator operates in the startup process and steady-state of SIDO DC-DC converter, a simplified design efficiently addresses high switching frequency losses at startup process and reduces chip area and power consumption. The proposed sub-1V input SIDO DC-DC converter was fabricated by TSMC 0.25 μm 2.5 V/5 V BCD process and the experimental results show a high efficiency of 92 % and a good cross-cross regulation smaller than 10 mV.

Abstract:
This chapter considers the potential of social software to support learning in higher education. It outlines a current project funded by the then Australian Carrick Institute for Learning and Teaching in Higher Education, now the Australian Learning and Teaching COuncil (ALTC) (http://www.altc. edu.au/carrick/go) to explore the role of social software in supporting peer engagement and group learning. The project has established a series of pilot projects that examine ways in which social software can provide students with opportunities to engage with their peers in a discourse that explores, interrogates and provides a supplementary social ground for their in-class learning. Finding creative ways of using technology to expand and enrich the social base of learning in higher education will become increasingly important to lecturers and instructional designers alike. This project represents one small step in testing the applicability of social software to these contexts. While many of our students are already using various technologies to maintain and develop their personal networks, it remains to be seen if these offer viable uses in more scholarly settings.

Abstract This study demonstrates a new methodology for the simultaneous direct measurement of temperature and heat flux within the same sensing element of heat-flux sensors. The methodology is demonstrated for fast response ALTP-sensors and makes use of a temperature-resistance correlation. The new methodology enables an inherent comparison and validation of the heat flux density signal of ALTPs. Good agreement is found based on experiments in the stagnation point of a subsonic hot air jet. The results of the mainly convective heat flux densities are compared against a standard coaxial thermocouple indicating good agreement of mean values and signal characteristics. The simultaneous direct measurement of the temperature and heat flux allows the time resolved calculation of local heat transfer coefficients and Nusselt numbers. The spectral analysis of the Nusselt number exhibits an excellent signal-to-noise ratio.

Abstract:
Abstract In view of the vibration failure of drilling string system in ultra-high temperature and high pressure (ultra-HPHT) curved wells, an axial-lateral-torsion coupling (ALTC) nonlinear vibration model of drilling string system was established using energy method and Hamiltonian principle, in which, the influence of wellbore trajectory change, wellbore constraint, interaction between bit and rock and ultra-HPHT of wellbore on elastic modulus and viscosity of drilling fluid were taken into account. The finite element method (FEM) is used to realize the numerical solution of the nonlinear vibration model. The correctness and validity of the ALTC nonlinear vibration model was verified by comparing the measured data of four ultra-HPHT wells with the theoretical calculation results of the proposed model. The research results provide a theoretically sound guidance for designing and practically sound approach for effectively improving rate of penetration (ROP) and the service life of drilling string in ultra-HPHT curved wells.

A novel heat flux sensor was tested which allows for time-resolved heat flux measurements in internal ribbed channels related to the study of passages in gas turbine blades. The working principle of the Atomic Layer Thermopile (ALTP) sensor is based on a thermoelectric field created by a temperature gradient over an YBCO crystal (the transverse Seebeck effect). The sensors very fast frequency response allows for highly time-resolved heat flux measurements up to the 1 MHz range. This paper explains the design and working principle of the sensor, as well as the benchmarking of the sensor for several flow conditions. For internal cooling passages, this novel sensor allows for highly accurate, time-resolved measurements of heat transfer coefficients, leading to a greater understanding of the influence of fluctuations in temperature fields.

Abstract:
Abstract In this study, the static calibration of different heat flux sensors in radiation- and convection-based procedures are compared. First, three heat flux sensors based on different principles: ALTP (based on the Transverse Seebeck Effect), HFM8E (differential-layer device) and a TG-2000 (circular-foil gage) are calibrated in a laser-based radiation setup and compared to the manufacturers calibration. In a second step, all three heat flux sensors are compared with standard temperature-based, robust heat flux measurement techniques (coaxial thermocouple and slug-calorimeter) within a newly built convection-dominated facility based on stagnation-point measurments of an impinging hot air jet. The obtained results show measurement principle depending divergences indicating that a sensitivity transfer between a radiative calibrated sensor used in a mainly convective environment is not always possible and can lead to significant, systematic errors. By comparing the time signal behavior of temperature based heat flux measurement techniques, benefits for direct heat flux measurement techniques are detected.
