Hematopoietic malignancies like leukemia and lymphoma are characteristically associated with various chromosomal translocations. Follicular lymphoma (FL) and mantle cell lymphoma (MCL) are two subtypes of non-Hodgkin's lymphoma which possess t(14;18) and t(11;14) translocations, respectively. The incidence of FL and MCL is higher in the western countries as compared to India. Interestingly, the associated translocations are also found in healthy individuals in western population, which is 50-80% for t(14;18), whereas t(11;14) occurs at a very low frequency. However, there are no studies to explore thes translocations in healthy Indian population, which could explain the lower incidence of FL and MCL. We employed Southern hybridization following nested PCR to detect above translocations in healthy individuals from India. Our results suggest that this assay can detect one t(14;18) translocation event in up to 10(7) normal cells where as one t(11;14) in 10(8) normal cells. According to our results, 87 out of 253 individuals carry t(14;18) indicating 34% prevalence in the population. The presence of this translocation was also detectable at the transcript level. Although, no gender-based difference was observed, an age-dependent increase in the prevalence of translocation was found in adults. However, even after studying 210 people, we could not detect any t(11;14) translocation, indicating that it is uncommon in Indian population. These results suggest that lower incidence of FL and MCL in India could be attributed to lower prevalence of these translocations in healthy individuals.

Den här avhandlingen handlar om lantbruksföretagare som genomgått yrkesinriktad rehabilitering. De har blivit tvungna att omskola sig till ett nytt yrke efter att de har insjuknat i yrkessjukdom eller skadat sig i ett olycksfall. Avhandlingens syfte är att öka förståelsen av hurdana erfarenheter lantbruksföretagare har av sin rehabiliteringsprocess. Rehabiliteringsätgärden, i det här fallet omskolningen, baserar sig på lagen om rehabilitering som ersätts enligt lagen om olycksfallsförsäkring. Materialet i avhandlingen bestär av 21 livsberättelser skrivna av de rehabiliterade som genomgått omskolningen. Undersökningen är därför narrativ tili sin natur. Analysen gjorde jag med hjälp av innehållsanalys och med hjälp av att tematisera innehållet i berättelserna. Tematiseringen var en central metod genom hela analysen och fungerade som ett redskap för att beskriva och tolka materialet. Rehabiliteringsprocessen frän början till slut ser jag även som ett identitetsprojekt och en process dar de rehabiliterade har varit tvungna att göra biografiskt arbete. Jag baserar min processindelning pä Corbin's och Strauss' (1988) defmition om att biografiskt arbete vid en krissituation i livet eller livsförändring innefattar fyra processer; kontextualisering, accepterande, äteruppbyggande av identiteten och omarbetning av biografin. Jag definierar insjuknandet eller skadan som en gemensam livsförändring för de rehabiliterade. De rehabiliterade har varit tvungna att konstruera en ny eller delvis en ny biografisk identitet som stämmer överens med de nya aktuella livsförhällandena, med framtida livsförhällanden och med tidigare erfarenheter. För största delen av de rehabiliterade hade rehabiliteringsprocessen varit en positiv erfarenhet och de hade lyckats med det biografiska arbetet för att återuppbygga identiteten och omarbeta biografin. Det var bara några av de rehabiliterade som ansåg att de inte hade haft någon nytta av rehabiliteringen. Det var personer som inte hade fått arbete efter omskolningen. Positiva studieerfarenheter och att man lyckas skaffa sig en utbildning i vuxen älder har för många varit faktorer som har gett dem bättre självkänsla och ökat deras självförtroende och dessutom skapat resurser för att kunna gå vidare i livet.

For studying systems containing nitrogen, limited use of N-14 NMR spectroscopy has been made because of the large quadrupolar interaction experienced by the N-14 nucleus and the absence of a central transition. To overcome the above problem, use of overtone spectroscopy has been suggested. Though this approach has limited applicability for powder samples due to second order quadrupole broadening, it is useful for studying oriented samples and single crystals. Here, we demonstrate the use of the recently proposed dipolar assisted polarization transfer (DAPT) pulse scheme for exciting the overtone transitions. The pulse sequence may also be utilized as a two-dimensional experiment to obtain H-1-N-14 dipolar couplings and H-1 chemical shifts. (C) 2010 Elsevier B.V. All rights reserved.

El presente estudio se realizó con el objetivo de determinar la calidad bromatológica (materia seca MS, proteína bruta PB, fibra neutro detergente FND), ácidos grasos volátiles AGV (ácido láctico, ácido acético, acido butírico) y pH del ensilaje de hoja de plátano (Musácea; variedad, FHIA-01), con dos niveles de inclusión de levadura de Torula (Candida utilis). El muestreo se realizó en la granja porcina y en los laboratorios de bromatología y microbiología de la Facultad de Ciencia Animal de la UNA. Los micro silos fueron conservados por 30 días. Los tratamientos evaluados fueron dos niveles de inclusión de levadura de Torula (Candida utilis al 0.5 y 1%). Los tratamientos se distribuyeron en un diseño completamente al azar (DCA) con tres repeticiones. El tratamiento uno (T1) consistió en hoja de plátano; el tratamiento dos (T2) en hoja de platano+melaza+0.5%levadura de Torula y el tratamiento tres (T3) en hoja de platano+melaza+1% levadura de Torula. Los resultados de la calidad bromatológica para MS por tratamiento fueron para T3:17.68%, T2: 17.22% y para T1: 16.46%. La PB alcanzó valores de: 14.08%, 13.50%, 13.12% para T3, T1 y T2, respectivamente. La FND presentó valores por tratamiento de T1: 67.80%, T3: 61.32% y T2: 56.39. Para los AGV, los resultados fueron para ácido láctico: T2 con 1.25%, T3 con 1.19% y T1 con 0.74%; para ácido acético T1 con 2.46%, T2 con 1.44% y T3 con 1.40; para ácido butírico no hubo presencia en ninguno de los tratamientos. Los resultados para el pH fueron para T1: 6.75%, para T3: 4.17% y para T2: 4.07. Con base en estos resultados, el T3 presentó mejor resultado en la calidad bromatológica y pH, superando al resto de los tratamientos, aunque obtuvo mejor resultado el T2 para el caso del ácido láctico. El uso de levaduras y melaza en el ensilaje mejora su calidad bromatológica.

A novel fish-specific apolipoprotein (apo-14 kDa) has been recently cloned from eel and pufferfish. However, its expression pattern has not been elucidated. in this study, EcApo-14 has been screened from hypothalamic cDNA library of male orange-spotted grouper, which shows 62.9%, 51%, 46.9%, 43.2%, and 31.9% identities to Apo-14 of European flounder, pufferfish, Japanese eel, gibel carp, and grass carp, respectively. RT-PCR analysis reveals that this gene is first transcribed in neurula embryos and maintains a relatively stable expression level during the following embryogenesis. EcApo-14 transcripts are at a very high level during embryonic and early larval development in the yolk syncytial layer (YSL), and decrease in YSL and form intense staining in liver at 3 days after hatching. In adult tissues, EcApo-14 is predominantly expressed in liver and brain. The data suggested that EcApo-14 might play an important role in liver and brain morphogenesis and growth.

In this paper, bioconversion of trans-cinnamic acid(t-Ca)to L-phenylalanine (L-phe) has been investigated by using immobilized yeast cells with induced L-phe Ammonia-lyase(PAL, EC.4.3.1.5) as biocatalysts. The contents are the following. (1) Thirty strains of yeasts, including two genera (Rhodotorula, Sporobolomyces), six species (R. glutinis R. minuta,R.rubra,R.sineses,R.roseus and S.salmonicolor)were screened for their ability to converse the substrates, t-Ca and ammonia, to the product, L-phe, by using yeast cells as biocatalyst, and primary evaluation for PAL activity of the selected strains was investigated. From the results of the screening experiments, it was found that 22 strains were able to produce L-phe from t-Ca with the range of conversion yield from 2% to 67%. Studies on PAL formation time course during cultivation show that the maximum PAL activity of several different strains ranges from 2.3 to 14.4×10-3U/mg cell dry weight. The biomass of tested strains at their maximum enzyme activity is also greatly varied. (2)One of the selected strains, R. rubra as 2.166, was used for immobilized cells as biocatalysts to produce L-phe. The optimum conversion conditions and effective stablization agents were investigated. The results shown that polyacrylamide gel was chosen as a suitable matrix for immobilization of the yeast cells, and it can retain 88% of the PAL activity in the reverse direction at the following reactive conditions: [t-Ca]: 34mM. [NH4OH]: 6.OM.PH10.00, temperature: 30℃. (3) The effects of various kinds of effectors on the production of L-phe were also examined. Membrane permeabilizing agents can stimulate L-phe synthesis, but make the stability of PAL decline greatly. Polyalchoholic agents and glutamic acid were very effective for the stabilization of PAL. At the presence of glutamic acid (5%), the half life of L-phe productivity with the immobilized cells was extended to 192 hours, which was much higher than most of that having been reproted, while the half life of resting cells was only about 15 hours. (4) Use of initial velocity studies on the kinetics of enzyme-catalized reaction indicated that the apparent Km value was 13.0mM for the immobilized cells, and 4.8mM for the resting cells. Thermostability of the immobilized cells was better than the resting cells. Fluid bed bioreactor is more effective than batch bioreator in prolonging the thermostability of the biocatalysts. (5) CGA- 688 resin column chromatographic procedure was employed in the isolation and purification of L-phe, t-Ca and other substances from the reactire mixture. (6) Preparative-scale production of L-phe on a level of gram amount by immobilized cells from the culture broth of R. rubra AS2.166 allowed for the conversion yield with 30%. The characteristic physico-chemical criteria (including melting point, optical activity, elements analysis, IR, NMR) are the same with the standard L-phe. 本文报告了利用诱导的苯丙氨酸解氨酶 (PAL.EC.4.3.1.5)催化反式肉桂酸(t-Ca)氨加 成制备L-苯丙氨酸(L-phe)的研究,主要内容为:(1) 我们搜集了三十株酵母菌株,利用全细胞转化t-Ca生成L-phe的能力进行了直 接筛选,并对其PAL活性水平进行了初步评估研究。研究结果表明,其中22株酵母具有转化t-Ca生产L-phe的能力,它们包括 Rhodotorula glutinis,R.rubra, R.sineses 和Sporobolomyces roseus 的菌株,转化率在2-67%。细胞生长和PAL形成过程的研究 表明,不同菌株PAL最大活力在2.3-14.4×10-3U/mg 细胞干重,达到最大PAL活性时各株酵母的生长情况也极不一致。(2) 利用筛 选出的一株深红酵母R.rubra AS2.166 作为供试菌株,研究了细胞固定化条件下生物转化的最适条件及PAL在固定化条件下的稳定 性。结果表明以聚丙烯酰胺凝胶包埋法较为理想,能使细胞合成L-phe活力保持88%,最适t-Ca浓度为34mM,最适NH4OH浓度为6M,最 适PH10.0,最适温度45℃。(3) 多种效应物对L-phe 合成的影响研究表明:表面活性剂能刺激L-phe的合成,但使PAL稳定性下降。 多羟基化合物及Glu对PAL的稳定十分有效在有Glu存在下,能使固定化细胞合成L-phe的半寿期达192小时左右,高于大部分现已报 导的固定化结果。(4) 用初速度法研究了深红酵母AS2.166中PAL的酶促反应特征,测得固定化细胞对t-Ca的表观米氏常数Km为 13.0mM,全细胞为4.8mM,细胞固定后热稳定性提高。(5) 建立了适合低浓度分离纯化产物与底物的聚苯乙烯大孔树脂柱层析技术 ,能使L-phe与t-Ca及产物混合物中其它成分有效分开。(6) 利用固定化的R.rubra AS2.166细胞所做的制备实验能够使L-phe的产 率达到30%左右,其主要的理化指标(包括熔点、比旋光度、元素分析、IR、NMR等)与标准L-phe一致。
