RNA silencing with direct delivery of siRNA has been used to suppress ldhA gene expression in filamentous fungus Rhizopus oryzae. Here, for the first time we show that, introducing small interfering RNA which consequently forms silencing complexes can alter the gene expression and we report a significant reduction of lactic acid production for isolates containing short (25 nt) synthetic siRNA. In all samples lactic acid production was reduced comparing with wild types. The average concentration of lactic acid production by Rhizopus oryzae during batch fermentation process where glucose has been used as a sole carbon source, diminished from 2.06 g/l in wild types to 0.36 g/l in knockdown samples which signify 5.7 times decrease. Interestingly, the average concentration of ethanol production was increased from 0.38 g/l in wild types to 0.45 g/l in knockdown samples. In some samples we were able to report even a 10 fold decrease in lactic acid production. Since R.oryzae is capable to assimilate a wide range of carbohydrates hydrolysed from lignocellulosic material in order to produce many economically valuable bulk material such as ethanol, these results suggest that RNA silencing is a useful method for industrial biotechnology to be applied in fungus Rhizopus oryzae in order to trigger the metabolism and gene expression toward a desired product.

Rockfish are commercially and recreationally important, yet due to the in habitat depths at which rockfish inhabit, little is known about their ecology. As a consequence, management of rockfish population as a fishery resource is a work in progress. In particular, changes in physiological condition aver the course of the year is poorly described. This study examined 19 different species of Sebastes from the Southern California Bight over four seasons (late summer, fall, winter, and spring) using metabolic enzyme assays. Enzymes used were lactate dehydrogenase (LDH), malate dehydrogenase (MDH), pyruvate kinase (PK), and citrate synthase (CS). Some muscle composition data (percent water, percent protein, percent lipid, and protein as a percentage of wet mass) were also used to help interpret the enzyme data. Enzyme activity was lowest in the summer when expressed as activity per gram wet weight but when it was expressed per gram protein the trend was reversed. We found that the rockfish tend to have the highest protein as a percentage of wet mass (P%WM) in the spring right before the upwelling period begins and have the lowest P%WM in late summer after the peak of upwelling. Their metabolic poise (represented as CS/LDH) grouped according to locomotory habit (benthic or bentho-pelagic). A mass and oxygen consumption plot also showed that the species group according to locomotory habit. With those known to be benthic grouped together and those species that are known to more actively swimming had higher values. This knowledge could be used to infer whether a rockfish that hasn't been well studied is benthic or bentho-pelagic.

Target cell lysis is the hallmark of immune effector responses of cytotoxic T lymphocytes (CTL), natural killer (NK) cells, and monocytes. The most commonly used assay to measure target cell lysis is the 51Cr release assay and is considered the ‘gold standard’. However, this assay has many disadvantages that limit its use by most laboratories. Thus, several alternative assays have been developed. Some of these alternative assays are more sensitive, easy to perform and do not use radioactive elements. In this study, four of these assays were evaluated for their ability to detect antigen- specific CTL responses in equine blood. Three long-term equine arteritis virus (EAV) carrier stallions, two vaccinated stallions and one naïve stallion were included in this study. Peripheral blood mononuclear cells (PBMCs) were isolated from whole blood collected of these stallions to be used as effector cells. The PBMCs were stimulated with EAV in vitro for 7-10 days to generate antigen-specific effector cells. The granzyme B assay, the Carboxyfluorescein succinimidyl ester (CFSE)/7-Aminoactinomycin D (7AAD) assay and the Lactate dehydrogenase (LDH) assay were performed using these effector cells and autologous equine dermal cells (isolated from each stallion) as target cells. The first two assays (i.e., granzyme B and CFSE/7AAD assays) were difficult to optimize for this study because they work well with non-adherent targets and require immediate flow cytometry analysis. The LDH assay, however detected CTL lysis in one of the two vaccinated stallions at day 99 post vaccination and no response was detected in PBMCs isolated from carrier stallions and control stallion. Based on these findings, the LDH assay is the most suitable assay since it works well with adherent target cells, it produces quantitative data, and is ideal for high-throughput screening.

Although clinical outcomes of some cancer have been greatly improved by advancements made in surgery, chemo or radiotherapy and development of novel strategies such as molecular targeted therapy, Traditional Chinese Medicine (TCM) is particularly appreciated for cancer therapy in China based on its 5,000-year-old history, well established theoretical system and numerous exciting case reports. However, due to lack of quality assurance, laboratory evidences and well-designed clinical trials, TCM always encounters much skepticism and pessimism by the West. The study aims to identify the bioactive compounds in a Chinese herb Spatholobus suberectus (SS, 雞血藤) by targeting on lactate dehydrogenase A (LDH-A) in breast cancer. Glycolysis inhibition has been considered as important strategy to block cancer energy metabolism and therefore suppressing cancer growth. LDH-A has been demonstrated to be up-regulated in various cancer cells. In our study, 46 breast cancer specimens were collected to study the relation between LDH-A expression and clinicopathological characteristics including menopause, tumor size, node involvement, differentiation and pathological subtypes classified by estrogen receptor (ER), progesterone receptor (PR) and Her-2. LDH-A expression was found to be correlated significantly with breast cancer size and independent with other clinicopathological factors. LDH-A silencing in breast cancer cell lines MDA-MB-231 and MCF-7 resulted in an inhibited breast cancer cell proliferation, elevated intracellular oxidative stress, induction of mitochondiral pathway apoptosis and limited tumorigenic ability, indicating that LDH-A inhibition might offer a promising therapeutic strategy for breast cancer. SS is historically recommended to invigorate blood circulation and has been prescribed to treat diseases relating to blood stasis syndromes including menstrual abnormalities, anemia, numbness of the limbs, arthritis and cancer, etc. Our following study revealed that SS aqueous extracts could significantly inhibited breast cancer LDH-A expression and activity in both in vitro and in vivo models built by MDA-MB-231 and MCF-7 cell lines. Bioactivity guided fractionation based on LDH-A activity, apoptosis and LDH-A expression further identified epigallocatechin (EGC) as the key compound responsible for the inhibited LDH-A expression. Mechanistic studies found that the inhibitory effect of EGC on LDH-A expression was mainly through promoting Hypoxia inducible factor-1α (HIF-1α) proteasome degradation rather than inhibiting transcription activity, which might be correlated with decreased binding between HIF-1α and Hsp90. Consistent with in vitro findings, EGC was also demonstrated effecitve in suppressing breast cancer growth in vivo correlating to down-regulation of LDH-A, HIF-1α and triggerment of apoptosis. This study provides preliminary laboratory evidences for applying SS in breast cancer therapy. However, further research is needed to evaluate its metabolism, the synergistic effects with chemotherapeutic agents and clinical efficiency. / published_or_final_version / Chinese Medicine / Doctoral / Doctor of Philosophy

Thus, classification of effusion in exudate and transudate is one of major points to elucidation of diagnosis and conduction of clinical case. In veterinary medicine the traditional method of an effusion classification is based on cellular counting and protein concentration of the fluid, however, several studies evidence that such parameters are not enough for the correct classification of all kinds of effusions. Considering this, the present study aimed to verify the correlation of some biochemical parameters with the differentiation of transudatives and exudatives effusions. To perform this, the activities of lactate dehydrogenase (LDH) and alkaline phosphatase (FA) were appraised, as well as the relationship of their activities with fluid/serum; lactate, cholesterol and proteins concentration and fluid/serum gradients of concentration of these same substances and albumin. The results allowed to observe that, among the appraised parameters, the activity of LDH, relationship LDH and fluid/serum, lactate concentration and lactate serum/fluid gradient of concentration present statistically significant difference (p<0,05), as well as a high correlation with the classification of an exudative and transudative effusion. Therefore, these parameters were shown to be more effective in the classification of an effusion when compared with total proteins concentration in the fluid / Doutor

Os testes físicos mais utilizados para determinar a aptidão física dos jogadores são: teste aeróbio intermitente de Yo-yo, velocidade de 10 e 30 metros, corridas repetidas anaeróbias (RSA, 6 x 20-20 m) e impulsão vertical squat e contra movimento (IVSQUAT e IVCMV). Entretanto, a relação entre o nível de aptidão física do jogador, seu desgaste durante a partida com a intensidade na qual ele joga e com as ações técnicas é pouco estudada. Diante disso, o presente estudo tem como objetivo: verificar se os jogadores que apresentam melhor desempenho nos testes físicos também têm maior participação com a bola e jogam em maior intensidade; verificar quais indicadores de dano muscular no jogo se relacionam com a aptidão física, as ações técnicas e a intensidade do jogo de futebol; bem como, verificar a relação entre CK, LDH e Mb com a intensidade do jogo. O presente estudo contou com 11 jogadores de futebol de uma equipe participante do Campeonato Paulista da primeira divisão. Os jogadores passaram por avaliação antropométrica e avaliação das capacidades físicas (Yo-yo, RSA, 10 e 30 metros e IV). A FC do jogo foi monitorada durante duas partidas oficiais para determinar a carga do jogo, pelo impulso de treinamento (TRIMP). Duas horas antes do início e após o jogo foram coletadas amostras de sangue (5 mL) para dosagem de Mb (pré-jogo e 30 min) e CK e LDH (pré-jogo e 24 h). As partidas foram filmadas para determinar as ações técnicas dos jogadores. A normalidade dos dados foi verificada com o teste de Shapiro-Wilk. Para determinar se houve diferença pré e pós-jogo entre CK, LDH e Mb foi realizado o teste - t Student. A relação entre os testes de aptidão física e ações técnicas, marcadores de dano tecidual e FC do jogo foi feita por meio da correlação de Pearson. O nível de significância foi fixado em p≤0,05. LDH correlacionou-se significantemente com os 10-m, enquanto que a Mb apresentou correlação com RSAdecai , IVCMV, 10-m e 30-m. TRIMP do jogo apresentou correlação com bola perdida, finalização certa e errada, Yo-yo e RSAmelhor. O número de desarmes teve correlação com o Yo-yo, RSAmelhor, 30-m, IVSQUAT e IVCMV, já os passes certos correlacionaram-se com IVSQUAT e os contatos com a bola com RSAmelhor, IVSQUAT e IVCMV. Mb apresentou maior sensibilidade com a aptidão física dos jogadores, em comparação com CK e LDH. TRIMP do jogo não tem relação com os marcadores de dano tecidual e, por fim, os jogadores com maior aptidão física apresentam melhores desempenhos técnicos. / Soccer is a sport with high intensity actions, involving an increase in tissue damage, which can be measured by the analysis of biochemical markers such as creatine kinase (CK), lactate dehydrogenase (LDH) and myoglobin (Mb). The physical tests most used to determine the physical fitness of the players are: Yo-yo intermittent aerobic test, 10 and 30 meters speed, repeated anaerobic races (RSA, 6 x 20-20 m) and vertical squat and counter-movement (IVSQUATand IVCMV). However, therelationship between the level of physical fitness of the player, his wear during the match with the intensity in which he plays and the technical actionsis little studied. Therefore, the present study has as objective: to verify if the players that present better performance in the physical tests also have higherparticipation with the ball and play in higherintensity; to verifywhich indicators of muscle damage in matches relate to physical fitness, technical actions and intensity of the soccermatch; as well as,toverifythe relationship amongCK, LDH and Mb with the intensity of the match. The present study had 11 soccer players from a team participating in the First Division Paulista Championship. The players underwent anthropometric evaluation and assessment of physical abilities (Yo-yo, RSA, 10 and 30 meters and IV). The HFof the game was monitored during two official matches to determine the loading of the game by the training impulse (TRIMP). Two hours before and after the game blood samples (5 mL) were collected for MB (pre-game and 30 min) and CK and LDH (pre-game and 24 h) dosages. The matches were filmed to determine the technical actions of the players. The determine the technical actions of the players. The normality of the data was verified with the Shapiro-Wilk test. In order to determine if there was pre and post-match difference between CK, LDH and Mb, Student-t-test was performed. The relationship between physical fitness tests and technical actions, markers of tissue damage and HR of the game was made through Pearson's correlation. The level of significance was set at p≤0.05. LDH was significantly correlated with 10-m, whereas Mb presented correlation with RSAdecai, IVCMV, 10-m and 30-m. TRIMP of the game presented correlation with lost ball, right and wrong finalization, Yo-yo and RSAbetter. The number of disarrangescorrelated with the Yo-yo, RSAbetter, 30-m, IVSQUATand IVCMV, and the correct passes correlated with IVSQUAT and the contacts with the ball with RSAbetter, IVSQUATand IVCMV. Mb presented greater sensitivity with the physical fitness of the players compared to CK and LDH. TRIMP of the game has no relation with the markers of tissue damage and, finally, the players with greater physical aptitude present better technical performances.

Sickle cell anemia is a disorder of genetic hemoglobin more common around the world, characterized by the presence of abnormal hemoglobin S. The phenomena of vaso-occlusion and anemia characteristics cause tissue damage leading to organ damage, including the kidneys. The various types of renal abnormalities occur primarily in the renal medulla. Clinical manifestations of sickle cell nephropathy start early, often before one year of age with glomerular hyperfiltration, hyposthenuria, renal tubular acidosis distal and, over time, increase in albuminuria. The lactate dehydrogenase (LDH) is considered a useful marker of hemolysis and its levels are very high in the presence of intravascular hemolysis, as indicated by some authors as associated with various complications related to hemolysis, including renal complications. In order to identify laboratory variables associated with renal injury in patients with sickle cell anemia, a cross-sectional study was conducted in children, teenagers and young adults treated in the hematology ward of the HU-UFS, from October 2010 to June 2011. Laboratory tests were performed in 124 patients with sickle cell anemia, mean age 13.3 + 6.4 years (2 - 32 years), 56.5 % were male. There was a frequency of microalbuminuria and proteinuria 19.4 % and 18.5% respectively. The frequency of glomerular hyperfiltration was 63.7 %. Elevation of LDH occurred in 95 % of patients and correlated positively with microalbuminuria, with percentages of reticulocytes and inversely with average rates of hemoglobin. Although univariate analysis revealed a significant positive correlation between the levels of LDH and microalbuminuria, these values were not significantly different between patients with or without microalbuminuria, suggesting that the association with renal injury is not specific, since it was also associated with markers of hemolysis. It is concluded that, levels of LDH present variability independently of microalbuminuria, because LDH levels were not able to distinguish patients with and without microalbuminuria. / A Anemia Falciforme é uma desordem da hemoglobina de caráter genético, mais comum em todo o mundo, caracterizada pela presença da hemoglobina anormal S. Os fenômenos de vaso-oclusão e anemia característicos da doença causam danos aos tecidos levando à lesão de órgãos, entre eles os rins. Os vários tipos de anormalidades renais ocorrem principalmente na medula renal. Manifestações clínicas de nefropatia falciforme começam cedo, muitas vezes antes de um ano de idade com hiperfiltração glomerular, hipostenúria, acidose tubular renal distal e, ao longo do tempo, aumento de albuminúria. A desidrogenase láctica (DHL) é considerada um marcador útil de hemólise e seus níveis encontram-se bastante elevados na presença de hemólise intravascular, sendo apontada por alguns autores como associadas a várias complicações relacionadas à hemólise, inclusive complicações renais. Com o objetivo de identificar variáveis laboratoriais associadas à lesão renal em portadores de anemia falciforme, foi realizado um estudo transversal em crianças, adolescentes e jovens adultos, atendidos no ambulatório de hematologia do HU-UFS, no período de outubro de 2010 a junho de 2011. Exames laboratoriais foram realizados em 124 pacientes com anemia falciforme, idade média de 13,3 + 6,4 anos (2 a 32 anos), 56,5 % do sexo masculino. Observou-se uma frequência de microalbuminúria e proteinúria de 19,4 % e 18,5 % respectivamente. A frequência de hiperfiltração glomerular foi de 63,7 %. Elevação de DHL ocorreu em 95 % dos pacientes e correlacionou-se positivamente com a microalbuminúria, com a contagem de reticulócitos e inversamente com taxas médias de hemoglobina. Apesar de a análise univariada revelar uma correlação positiva significativa entre os níveis de DHL e microalbuminúria, estes valores não foram significativamente diferentes entre os pacientes com ou sem de microalbuminúria, sugerindo que a associação com lesão renal não é específica, uma vez que houve também associação com marcadores de hemólise. Conclui-se que, níveis de DHL apresentam variabilidade de forma independente da microalbuminúria, pois níveis de DHL não foram capazes de discriminar pacientes com ou sem microalbuminúria.

As atividades enzimáticas e isoenzimáticas da CK e da LD foram determinadas nos tecidos gástricos neoplásico e da margem de ressecção e no soro de indivíduos com adenocarcinoma de estômago, submetidos à gastrectomia. O tecido gástrico neoplásico aapresentou índices CKBB/Cktotal e LD5/LD1, bem como atividade da LD5, superiores aos da margem de ressecção correspondente. No pré-operatório, os indivíduos estudados apresentaram elevação da atividade sérica da CK BB (100%) e da CK MB (69%). Este fato, possivelmente, resultou da liberação dessas isoenzimas pelo próprio neoplasma ou, também pelo tecido normal adjacente. As atividades séricas das isoenzimas da LD apresentaram-se dentro dos valores de referência, nesse período. Após a gastrectomia, houve aumento significativo das atividades isoenzimáticas séricas da CK e da LD relação àquelas do pré-operatório, notadamente, no 1º período pós-operatório. Tais alterações foram atribuídas à liberação dessas isoenzimas pelos tecidos lesados durante o ato cirúrgico. / Abstract not available

The infrequency of known T cell targets in high grade serous ovarian carcinoma (HSGC) is a substantial barrier to the development of targeted immunotherapies. Due to their infrequency, antigen discovery is a crucial component of immunotherapeutic design. In our cohort of HGSC cases, the cancer testis (CT) antigen lactate dehydrogenase C (LDHC) is expressed in 76% of tumours (22/29). As LDHC presents with tumour specificity in women, I hypothesize that LDHC is an immunogenic target in HGSC patients, and that LDHC-specific T cells can be activated and expanded for therapeutic purposes. As such, I sought to examine whether endogenous LDHC-specific T cells were present in the ascites of HGSC patients. A standard Rapid Expansion Protocol was used to expand CD8 T cell cultures from patient ascites. These cultures were screened for reactivity to a peptide library encompassing all possible epitopes of the LDHC protein by interferon-γ ELISpot. With this approach, T cell clones from one of five patients were identified that were reactive to minimal peptides contained within LDHC. In this patient, the antigenic LDHC peptide differentiated from LDHA by a single amino acid at its C-terminus (YTSWAIGLSVM versus YTSWAIGLSVA). In recognition assays, tumour cell lines expressing endogenous LDHC, autologous ascites, or autologous B cells transfected with LDHC were unable to elicit T cell responses. Although this study suggests that LDHC is not immunogenic, continued screening of LDHC and other CT proteins will likely provide additional immunotherapeutic targets. / Graduate
