Abstract:

Cholangiocarcinoma is a rare type of cancer which is an increasingly discernible health threat. The disease is usually very difficult in diagnosis and various treatment modalities are typically not effective. Cholangiocarcinoma is a complex and very heterogeneous malignancy characterized by tumor location, different risk factors, molecular profiling, and prognosis. Cancer cell lines represent an important tool for investigation in various aspects of tumor biology and molecular therapeutics. We established two cell lines, KKU-452 and KKU-023, which were derived from patients residing in the endemic area of liver fluke infection in Thailand. Both of tumor tissues have gross pathology of perihilar and intrahepatic mass-forming cholangiocarcinoma. Two cell lines were characterized for their biological, molecular and genetic properties. KKU-452 and KKU-023 cells are both adherent cells with epithelium morphology, but have some differences in their growth pattern (a doubling time of 17.9 vs 34.8 h, respectively) and the expression of epithelial bile duct markers, CK7 and CK19. Cytogenetic analysis of KKU-452 and KKU-023 cells revealed their highly complex karyotypes; hypertriploid and hypotetraploid, respectively, with multiple chromosomal aberrations. Both cell lines showed mutations in p53 but not in KRAS. KKU-452 showed a very rapid migration and invasion properties in concert with low expression of E-cadherin and high expression of N-cadherin, whereas KKU-023 showed opposite characters. KKU-023, but not KKU-452, showed in vivo tumorigenicity in xenografted nude mice. Those two established cholangiocarcinoma cell lines with unique characters may be valuable for better understanding the process of carcinogenesis and developing new therapeutics for the patients

Abstract:

Cholangiocarcinoma (CCA) is a bile duct cancer, commonly found in Asia including Thailand and especially in the northeastern region of Thailand. To identify the proteins involved in carcinogenesis and metastasis of CCA, protein expression profiles of high-invasive KKU-M213 and low-invasive KKU-100 cell lines were compared using a comparative GeLC-MS/MS proteomics analysis. A total of 651 differentially expressed proteins were detected of which 27 protein candidates were identified as having functions involved in cell motility. A total of 22 proteins were significantly upregulated in KKU-M213, whereas 5 proteins were downregulated in KKU-M213. S100A2, a calcium-binding protein in S100 protein family, is upregulated in KKU-M213. S100A2 is implicated in metastasis development in several cancers. The protein expression level of S100A2 was verified by Western blot analysis. Intriguingly, high-invasive KKU-M213 cells showed higher expression of S100A2 than KKU-100 cells, consistent with proteomic data, suggesting that S100A2 may be a key protein involved in the progression of CCA. However, the biological function of S100A2 in cholangiocarcinoma remains to be elucidated. S100A2 might be a potential biomarker as well as a novel therapeutic target in CCA metastasis.

Abstract:

Coconut crab (Birgus latro) is a fishery resource with high economic value. Coconut Crab is only found in eastern Indonesia, covering Sulawesi, Maluku and North Maluku. One of the habitat of Coconut Crab in North Maluku is Moor Island, Central Halmahera. The coastal typology of this island is predominantly rocky with many gaps and small caves, as well as several steep slopes with dominant vegetation conditions of coconut, beach pandanus and other coastal plants. Walnut Crab is often used as a consumption ingredient because it has delicious taste and high nutritions. However, the use of crustaceans for consumption can also be dangerous. This is because crustaceans also contain several pathogenic bacteria. This study aimed to identify pathogenic bacteria isolated from Coconut Crab which is the largest crustacean in the world. 5 samples of Coconut Crab were taken from Moor Island. Isolated samples marked KK1, KK2, KK3, KK4 and KK5. Pure bacterial isolates were obtained from Coconut Crab samples, evaluated for colony type and identified based on biochemical characterization. The types of pathogenic bacteria identified in samples KK1, KK2, KK3, KK4 and KK5 were Escherichia coli, Pseudomonas sp. and Staphylococcus sp.

Abstract:

Cholangiocarcinoma (CCA) is a highly metastatic tumor, and the majority of patients with CCA have a short survival time because there are no available effective treatments. Hence, a better understanding regarding CCA metastasis may provide an opportunity to improve the strategies for treatment. A comparison study between the highly metastatic cells and their parental cells is an approach to uncover the molecular mechanisms underlying the metastatic process. In the present study, a lung metastatic CCA cell line, KKU-214L5, was established by the in vivo selection of the tail vein-injected mouse model. KKU-214L5 cells possessed mesenchymal spindle-like morphology with higher migration and invasion abilities in vitro than the parental cells (KKU-214). KKU-214L5 also exhibited extremely aggressive lung colonization in the tail vein-injected metastatic model. Epithelial‐mesenchymal transition (EMT) was clearly observed in KKU-214L5 cells. Significant downregulation of epithelial markers (ZO-1 and claudin-1), with unique upregulation of E-cadherin and mesenchymal markers (vimentin, β-catenin, and slug), was observed in KKU-214L5. Increasing MMP-2 and MMP-9 activities and CD147 expression reflected the high invasion activity in KKU-214L5 cells. Suppression of vimentin using siRNA significantly decreased the migration and invasion capabilities of KKU-214L5 to almost the basal levels of the parental cells without any change on the expression levels of other EMT markers and the activities of MMPs. These results suggest that vimentin activation is essential to potentiate the metastatic characters of CCA cells, and suppression of vimentin expression could be a potential strategy to improve the treatment of CCA, a highly metastatic cancer.

Abstract:

An actinomycete strain (KKU-A3) with algicidal activity against Microcystis aeruginosa was isolated from soil in Khon Kaen Province, Thailand. Based on its phenotypic characteristics and 16S rDNA sequence, strain KKU-A3 was identified as Streptomyces rameus. Strain KKU-A3 also exhibited algicidal activity against the cyanobacteria Synechococcus elongatus, Cylindrospermum sp. and Oscillatoria sp. A mathematical and statistical technique was used to optimize the culture conditions and maximize its anti-Microcystis activity. The single factor experiments indicated that glucose and casein were the most effective carbon and nitrogen sources, respectively, and produced the highest anti-Microcystis activity. Response surface methodology indicated that the optimum culture conditions were 19.81 g/L glucose and 2.0 g/L casein at an initial pH of 7.8 and an incubation temperature of 30 °C. The anti-Microcystis activity increased from 82% to 95% under optimum conditions. In an internal airlift loop bioreactor, the removal of M. aeruginosa KKU-13 by the bacterium was investigated in batch and continuous flow experiments. In the batch experiment, KKU-A3 displayed maximum anti-Microcystis activity of 95% at day 7, whereas in the continuous flow experiment, KKU-A3 displayed maximum anti-Microcystis activity of 95% at day 10.

Abstract:

This research aims to investigate the impact of employing the learning management system (Blackboard) on attitudes of King Khalid University (KKU) students. The research examines the students' knowledge and skills in employing the Blackboard in their learning process, and investigates the elements, which influence the students' attitude and performance in using Blackboard in classroom instruction from their perspectives. To this end, the author has selected a sample of 34 of KKU students, where they have been requested to complete a 14-item questionnaire. Findings of the current study revealed that KKU students faced several difficulties in learning English language vocabulary. Consequently, the students have developed negative attitudes towards English vocabulary. The study found that Blackboard had a little influence on the attitude and performance of the KKU students in vocabulary learning. The study also showed that there were some limitations in the use of Blended Learning. It needs an action plan in order to make supportive learning opportunities for the university students.

Abstract:

this is the extended research work where we tried to add more sections in Quality instruments to their role in achieving interoperability in e-learning and quality. In this paper we included more reference models such as experiences of Quality instruments affected by demographic criteria. In Higher education systems E-Learning faces two major challenges, first to ensure the interoperability of E-Learning (IEL) and secondly, developing quality learning through e-Learning. This research studies the concept, scope and dimensions of interoperability of E-Learning in education with special reference to King Khalid University then the connection and interdependence between with quality development. To impart learning and teaching through E-learning, KKU has adopted Learning Management Services (LMS) through Blackboard. The university has three types of learning and teaching methods; full online, Blended and Supportive. In this paper we have described the dimensions of quality and the standards of E- Learning for the objectives of IEL and quality development (QD) in KKU. The research is based principally on secondary data observed from KKU E-Learning deanship. Also sample of 20 E-Learning experts at KKU were given closed ended as well as semi closed questionnaires for evaluating the assurance of IEL and QD. These experts are mainly certified online facilitators and admin staff. Results provide the verification of application and presence of IEL and assured the QD process in KKU in imparting knowledge.

Abstract:

Drought remains the most important factor that affects rice productivity, especially in rainfed areas, worldwide. Upland rice is one of the crop choices of farmers in the rainfed environment. Although upland rice varieties require less water than lowland rice varieties, yields often remain limited by drought, particularly in the period of early growth. The aims of this study were to identify the traits related to early drought tolerance in upland rice varieties, and to identify the potential sources of germplasm for early drought tolerance. A total of sixty upland rice varieties were planted in a factorial experiment with a randomized complete block design with 3 replications in the rainy seasons of 2011 and 2012, under greenhouse conditions. Based on the drought tolerance index (DTI), the test germplasm sources were classified into three groups: (i) susceptible; (ii) moderately tolerant; (iii) tolerant to drought stress. Grain yield (GY) showed significant negative correlations with the leaf rolling score (r= − 0.623, P< 0.01), the leaf death score (LDS) (r= − 0.673, P< 0.01) and the recovery score (r= − 0.746, P< 0.01), while leaf dry matter (r= 0.698, P< 0.01) and leaf water potential (r= 0.618, P< 0.01) had significant positive correlations with GY. These findings indicate the suitability of the DTI as the selection criteria for early drought tolerance in a breeding programme. In addition, the upland rice germplasm accessions KKU-ULR011, KKU-ULR012, KKU-ULR125, KKU-ULR199 and KKU-ULR292 were identified as having high levels of stability for drought tolerance in both the 2011 and 2012 experiments, suggesting their potential for further use for rice variety improvement for drought tolerance.

Abstract:

Anemia is a global public health problem. The prevalence of anemia among different ages, genders or ethnic groups must be clarified in order to solve problems. This study proposed to determine the prevalence and factors related to anemia among the Muslim school-age population in Nakhon Si Thammarat, Thailand. Socio-demographic and anthropometric data were collected by a structured questionnaire. Blood samples were collected from 200 school-age subjects. The thalassemia screening was performed with KKU-OF and KKU-DCIP reagents. The prevalence of anemia in this study was 36.5%, divided into males and females, 33.3% and 39.1%, respectively. The means of Hb, Hct, MCV, MCH, and MCHC in the anemic group were significantly lower. The positive results for KKU-OF or KKU-DCIP or both were 15.0%, 2.5%, and 1.0%, respectively. The result of positive OF test was a significantly independent factor for anemia. The number of family members was 5 to 7 and more than 7 persons are related factors for anemia in this study. In summary, the contribution of thalassemia and socio-economic factor are associated factors to anemia in this population. These findings should be addressed in public health strategies for the control of anemia of school-aged Muslims in the region.

Abstract:

The objective of this study was to identify the maize inbred lines with good general combining ability (GCA), good specific combining ability (SCA), high heterosis for yield and phytochemicals, and the crosses with high yield of yellow kernels and high anthocyanin content in cobs and husk, which was probably related to the high antioxidant activity. The parental lines including five unpigmented females and five pigmented males were crossed in North Carolina design II. The parents, the resulting 25 hybrids, and 5 controls were evaluated at two locations in the dry season of 2016/2017. Additive and non-additive gene effects controlled the inheritance of grain yield, agronomic traits, and phytochemicals. KKU–PFC2 and KKU–PFC4 had the highest GCA effects for phytochemical traits in husk and cob, whereas Takfa1 and Takfa3 were good combiners for grain yield. F1 hybrids had significantly higher total anthocyanin content (TAC), total phenolic content (TPC), (2,2-diphenyl-1-picrylhydrazyl) (DPPH), and trolox equivalent antioxidant capacity (TEAC) in husk and cob than pigmented control cultivars. The hybrids superior for individual traits were identified, but the experiment was not able to identify superior hybrids for multiple traits. The Takfa3 × KKU–PFC5 and NakhonSuwan2 × KKU-PFC4 had the highest anthocyanin in husk and cobs, respectively. The breeding strategies to develop maize varieties with high anthocyanins and normal yellow kernels and utilization of the hybrids are discussed.

Abstract:

Cholangiocarcinoma (CCA) is a major cause of mortality in Northeast Thailand with about 14,000 deaths each year. There is an urgent necessity for novel drug discovery to increase effective treatment possibilities. A recent study reported that lignin derived from Scoparia dulcis can cause CCA cell inhibition. However, there is no evidence on the inhibitory effect of coniferyl alcohol (CA), which is recognized as a major monolignol-monomer forming a very complex structure of lignin. Therefore, we aimed to investigate the effect of CA on CCA cell apoptosis. We demonstrated that a half-inhibitory concentration of CA on KKU-100 cells at 48 h and 72 h was 361.87 ± 30.58 and 268.27 ± 18.61 μg/mL, respectively, and on KKU-213 cells 184.37 ± 11.15 and 151.03 ± 24.99 μg/mL, respectively. Furthermore, CA induced CCA cell apoptosis as demonstrated by annexin V/PI staining in correspondence with an increase in the BAX/Bcl-2 ratio. A metabonomic study indicated that CA significantly decreased the intracellular concentrations of glutathione and succinate in KKU-213 cells and increased dihydrogen acetone phosphate levels in KKU-100 cells treated with 200 µg/mL of CA compared to the control group. In conclusion, CA induced cellular metabolic changes which are involved in the antioxidant defense mechanism, glycerophospholipid metabolism and the tricarboxylic acid cycle. CA may serve as a potent anticancer agent for CCA treatment by inducing CCA cellular apoptosis.

Abstract:

This research aims to assess the importance of Extensive Reading (ER) in developing reading comprehension, vocabulary development, and speaking fluency among English as a Foreign Language (EFL) students at King Khalid University (KKU). Most EFL students appear to be under pressure and confront anxiety while acquiring English language competency in basic language skills. According to MacIntyre and Gardner (1994, p. 284), language anxiety is the "feeling of tension and apprehension" with language learning, including listening, speaking, and language comprehension. One thought of making language learning an enjoyable activity is to make language acquisition a natural process instead of a forced and external one. According to Day & Bamford (2002), the goal of ER is to help students become fluent, independent, and confident readers. ER encourages L2 learners to explore the English language independently, especially in an EFL environment. ER inherently encourages language acquisition by allowing students to read extensively in a relaxed and natural environment, thus developing the basic nuances of the language effortlessly. This approach is also referred as uninterrupted sustained silent reading (USSR). Two distinct groups of students, namely experimental and control groups, will participate in this study. The results will help measure the effect of ER on students’ reading comprehension and speaking fluency. The experimental group will practice effortless ER for almost 12 weeks. Students' performance in the assigned reading task, vocabulary development, and speaking proficiency will be analyzed using SPSS. Finally, the researchers will suggest efficient measures to implement ER as a teaching methodology at the English department, and will also encourage implementation of an ER club at the faculty of languages and translation, KKU.

Abstract:

The use of a chili fruit is distinguished by its capsaicinoid content, which shows many beneficial effects in food and pharmaceutical applications. However, chilies exhibit wide variations in the accumulation of capsaicinoids depending on their genotype and environmental interaction. Therefore, we conducted experiments to evaluate the capsaicinoid responses of 14 cultivars of chili across four different elevations. Experiments were conducted during the rainy season from June to Oct. 2009 at elevations of 200 m asl (Khon Kaen) and 680 m asl (Chiang Mai) in Thailand and from Apr. to Sept. 2010 at elevations of 1400 m asl (Lobesa) and 1630 m asl (Kabesa) in Bhutan. A high-performance liquid chromatography technique was used to determine capsaicin and dihydrocapsaicin. Significant differences were observed among the cultivars, the locations, and the cultivar-by-location interactions. Large variations of cultivar effects indicate that it is possible to select cultivars for capsaicinoid concentration that are adapted over a wide range of environments. Average capsaicin, dihydrocapsaicin, and total capsaicinoids were greater at higher elevations in a particular year. There was significant correlation between capsaicin and total capsaicinoid contents with elevations, but capsaicinoid yield showed negative correlation. Small-fruited cultivars with high pungency showed consistent capsaicinoid production over different environments. Dallay khorsaney, KKU-P-22006, KKU-P-31141, and KKU-P-21041 cultivars showed high stability for pungency, producing high capsaicinoids at all four locations.

Abstract:

ABSTRACT This questionnaire survey of recent graduates was carried to find out the strengths and weaknesses of the undergraduate training program for dentists at the King Khalid University College of Dentistry (KKU/COD), Saudi Arabia. The questionnaire focussed on seven key areas of interest to a pioneer dental school, in a region where many patients are visiting the dentist for the first time. Almost all the graduates surveyed returned completed questionnaires (99% response rate). Study was conducted at the end of the internship year. Respondents were generally satisfied with the quality of their training, skills acquired, the adequacy of tools of training (clinical and laboratory equipment). Training was also adjudged relevant and adequate for future practice as General Dental Practitioners. Most of the respondents planned to undergo postgraduate training in a dental specialty after the internship year. Two areas of weakness were cited by survey participants—inadequate patients and patient referral system, clinical support staff-related issues. Much more was expected of faculty and support staff than the program provided during their training. It is hoped that findings of this survey will be considered along with other on-going evaluations of the KKU/COD program in the continuous improvement of the BDS training.

Abstract:

Abstract The occurrence of trihalomethanes (THMs) and haloacetonitriles (HANs) in three water distribution networks (Thapra, Kota, and Khon Kaen University (KKU)) in Khon Kaen Municipality, Thailand, from November 2015 to December 2016 was investigated. The highest THMs and HANs were 584 μg/L and 30 μg/L, respectively. Chloroform was the dominant species of the THM pool and trichloroacetonitriles were the dominant species for HANs. Water treatment plants using free chlorine (Thapra and Kota) formed more THMs than the plant using ClO2 (KKU). In the summer season, more brominate THMs were observed. In many locations, total THM concentrations were found to be higher than the drinking water standard of the Provincial Water Authority of Thailand. The concentration of THMs tended to increase with greater distance from the water plants (as water aged), while HAN concentrations decreased with distance, potentially because they were undergoing hydrolysis in the pipeline.

Abstract:

Photo-hydrogen and lipid production from individual synthetic volatile fatty acids (VFAs) and sugar manufacturing wastewater (SMW) byRhodobactersp. KKU-PS1 with sodium glutamate or Aji-L (i.e., waste from the process of crystallizing monosodium glutamate) as a nitrogen source was investigated. Using individual synthetic VFAs, the maximum hydrogen production was achieved with Aji-L as a nitrogen source rather than sodium glutamate. The maximum hydrogen production was 1,727, 754 and 1,353 mL H2/L, respectively, using 25 mM of lactate, 40 mM of acetate and 15mM of butyrate as substrates. Under these conditions, lipid was produced in the range of 10.6–16.9% (w/w). Subsequently, photo-hydrogen and lipid production from SMW using Aji-L as nitrogen source was conducted. Maximal hydrogen production and hydrogen yields of 1,672 mL H2/L and 1.92 mol H2/mol substrate, respectively, were obtained. Additionally, lipid content and lipid production of 21.3% (w/w) and 475 mg lipid/L were achieved. The analysis of the lipid and fatty acid components revealed that triacyglycerol (TAG) and C18:1 methyl ester were the main lipid and fatty acid components, respectively, found inRhodobactersp. KKU-PS1 cells.

Abstract:

Zinc finger protein 423 (ZNF423) is a transcriptional factor involved in the development and progression of cancers but has not yet been examined in cholangiocarcinoma (CCA), an oxidative stress-driven cancer of biliary epithelium. In this study, we hypothesized that oxidative stress mediated ZNF423 expression regulates its downstream genes resulting in CCA genesis. ZNF423 protein expression patterns and 8-oxodG (an oxidative stress marker) formation in CCA tissues were investigated using immunohistochemical analysis. The results showed that ZNF423 was overexpressed in CCA cells compared to normal bile duct cells adjacent of the tumor. Notably, ZNF423 expression was positively correlated with 8-oxodG formation. Moreover, ZNF423 expression in an immortalized cholangiocyte cell line (MMNK1) was increased by hydrogen peroxide-treatment, suggesting that oxidative stress induces ZNF423 expression. To investigate the roles of ZNF423 in CCA progression, ZNF423 mRNA was silenced using specific siRNA in CCA cell lines, KKU-100 and KKU-213. Silencing of ZNF423 significantly inhibits cell proliferation and invasion of both CCA cell lines. Taking all these results together, the present study denoted that ZNF423 is an oxidative stress-responsive gene with an oncogenic property contributing to the regulation of CCA genesis.

Abstract:

Unlike normal cells, cancer cells undergo unlimited growth and multiplication, causing them to require massive amounts of amino acid to support their continuous metabolism. Among the amino acid transporters expressed on the plasma membrane, l-type amino acid transporter-1, a Na+-independent neutral amino acid transporter, is highly expressed in many types of human cancer including cholangiocarcinoma. Our previous study reported that l-type amino acid transporter-1 and its co-functional protein CD98 were highly expressed and implicated in cholangiocarcinoma progression and carcinogenesis. Therefore, this study determined the effect of JPH203, a selective inhibitor of l-type amino acid transporter-1 activity, on cholangiocarcinoma cell inhibition both in vitro and in vivo. JPH203 dramatically suppressed [14C]l-leucine uptake as well as cell growth in cholangiocarcinoma cell lines along with altering the expression of l-type amino acid transporter-1 and CD98 in response to amino acid depletion. We also demonstrated that JPH203 induced both G2/M and G0/G1 cell cycle arrest, as well as reduced the S phase accompanied by altered expression of the proteins in cell cycle progression: cyclin D1, CDK4, and CDK6. There was also cell cycle arrest of the related proteins, P21 and P27, in KKU-055 and KKU-213 cholangiocarcinoma cells. Apoptosis induction, detected by an increase in trypan blue–stained cells along with a cleaved caspase-3/caspase-3 ratio, occurred in JPH203-treated cholangiocarcinoma cells at the highest concentration tested (100 µM). As expected, daily intravenous administration of JPH203 (12.5 and 25 mg/kg) significantly inhibited tumor growth in KKU-213 cholangiocarcinoma cell xenografts in the nude mice model in a dose-dependent manner with no statistically significant change in the animal’s body weight and with no differences in the histology and appearance of the internal organs compared with the control group. Our study demonstrates that suppression of l-type amino acid transporter-1 activity using JPH203 might be used as a new therapeutic strategy for cholangiocarcinoma treatment.

Abstract:

256 Background: Trastuzumab emtansine (T-DM1) is an antibody-drug conjugate composed of trastuzumab and DM1 (an anti-microtubule agent derived from maytansine) that is approved for the treatment of HER2-positive metastatic breast cancer. HER2-overexpression rate in biliary tract cancer (BTC) is reported as approximately 10%, and HER2-targeted therapy may enhance therapeutic efficacy in HER2-positive BTC. In this study, we investigated the antitumor activity of T-DM1 in several BTC cell lines and xenograft models. Methods: HER2 expression was detected by flow cytometry and Western blotting in 17 BTC cell lines. The cell growth inhibition activity of T-DM1 and DM1 was examined by quantifying the DNA with Hoechst 33258 nucleic acid stain. In vivo antitumor activity of T-DM1 was evaluated in three xenograft mouse models using cell lines with different levels of HER2 expression. HER2 expression in xenografts was assessed by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH), according to gastric cancer criteria. Cell cycle was assessed by flow cytometry after staining with propidium iodide. Apoptosis was assessed by caspase 3/7 activity measurement. Results: In the 17 BTC cell lines, HER2 expression was high in KMCH-1, Mz-ChA-1, and TGBC-18-TKB. Although cell growth inhibition of DM1 was similar in all cell lines (50% inhibitory concentration (IC50): 0.79–7.2 nM), that of T-DM1 was HER2-expression-dependent, with IC50 values in KMCH-1, Mz-ChA-1, and KKU-100 (which has low HER2 expression) of 0.031, 1.3, and 4.3 μg/mL, respectively. In KMCH-1 and Mz-ChA-1 xenograft models, T-DM1 treatment once every 3 weeks for 6 weeks showed significant dose-dependent antitumor activity, and tumor growth inhibition 21 days after first dose at 20 mg/kg T-DM1 was 108% (KMCH-1) and 75% (Mz-ChA-1), whereas there was no significant efficacy in KKU-100 xenograft model. Values for HER2 status (IHC score/FISH ratio of HER2 to CEP17) in KMCH-1, Mz-ChA-1, and KKU-100 tumor tissues were 3+/3.5, 2+/4.7, and 0/1.1, respectively. In KMCH-1, T-DM1 induced M phase arrest and apoptosis, as is reported in HER2-positive breast cancer cells. Conclusions: T-DM1 could be an effective therapy for HER2-overexpressed BTC.

Abstract:

Introduction: Patient satisfaction is important for ensuring patients adherence in orthodontic treatment. As teaching institutions, dental college clinics must constantly strive to find a balance between satisfying the needs of the patients and ensuring proper training of the students. The objective of the present study was to assess dental patients satisfaction with orthodontic treatment and related services at King Khalid University, College of Dentistry (KKU COD), Saudi Arabia.Materials and methods: A 19 item closed end questionnaire was developed and pretested to assess patients satisfaction with orthodontic care. The questionnaire items were designed under three domains: 1) Reception and work environment, 2) doctor-patient relationship, and 3) treatment expectations and satisfaction. The study sample consisted of all patients consulting the orthodontic clinics during the time frame of the survey and those who were willing to participate.Results: A total of 72 patients completed the survey within the time framework. The mean age of the patients was 21.2±8.06 of which males were 69.5% and Females 30.5%. The highest subscale score was found to be with patients treatment expectations and satisfaction (92.6%) followed by reception and work environment (89.3%) and dentist-patient relationship (82.7%). The overall patients satisfaction for orthodontic services among the patients was found to be 87.1%.Conclusion: There was a high dental patients satisfaction with orthodontic services at COD KKU, Saudi Arabia as a teaching institution. The dentist-relationship was found to be key factor in determining dental patients satisfaction.Bangladesh Journal of Medical Science Vol.14(2) 2015 p.146-150

Abstract:

Altered expression of a cytosolic flavoenzyme NAD(P)H:quinone oxidoreductase-1 (NQO1) has been seen in many human tumors. Its remarkable overexpression in cholangiocarcinoma (CCA; an aggressive malignancy of the biliary duct system) was associated with poor prognosis and short survival of the patients. Inhibition of NQO1 has been proposed as a potential strategy to improve the efficacy of anticancer drugs in various cancers including CCA. This study investigated novel NQO1 inhibitors and verified the mechanisms of their enzyme inhibition. Among the different chemical classes of natural NQO1 inhibitors are coumarins, flavonoids, and triterpenoids. Coumarins are a group of particularly potent NQO1 inhibitors. The mechanisms and kinetics of enzyme inhibition of coumarin, aesculetin, umbelliferone, and scopoletin using the cell lysates as a source of NQO1 enzyme best fit with an uncompetitive inhibition model. Among the NOQ1 inhibitors tested in KKU-100 CCA cells, scopoletin and umbelliferone had the strongest inhibitory effect on this enzyme, while aesculetin and coumarin barely affected intracellular NQO1. All coumarins were further tested for cytotoxicity and anti-migration activity. At modest cytotoxic doses, scopoletin and umbelliferone greatly inhibited the migration of KKU-100 cells, whereas coumarin and aesculetin barely reduced cell migration. The anti-migration effect of scopoletin was associated with decreased ratio of matrix metalloproteinase 9/tissue inhibitors of metalloproteinases 1 ( MMP9/ TIMP1) mRNA. These findings suggest that natural compounds with potent inhibitory effect on intracellular NQO1 have useful anti-migration effects on CCA cells. In order to prove that the potent NQO1 inhibitor, scopoletin, is clinically useful in the enhancement of CCA treatment, additional in vivo studies to elucidate the mechanism of these effects are needed.

Abstract:

Waxy corn is a popular, alternative staple food in most Asian countries including Thailand. The availability of small-ear waxy corn genotypes with prolific ears and a high level of carotenoids is expected to benefit growers and consumers. Integrated evaluation among source germplasm is essential before performing further breeding efforts for enhancing prolific ears and high-carotenoid content. Thus, the present study explored the variability of ear prolificacy, total carotenoids, lutein, zeaxanthin, and beta-carotene among yellow small-ear waxy corn accessions. About 44 corn accessions and 4 check varieties were evaluated for agronomic traits and yield components under multienvironment trials in a randomized complete block design (RCBD). The immature seed sample of these genotypes was analyzed to quantify the content of total carotenoids and some carotenoid fractions. All traits showed that low GXE interaction and significant genotypic diversity existed among all tested accessions with the predominant contribution of genotype to total phenotypic variation and beta-carotene. Accessions were clustered into four major groups based on the similarity of multiple carotenoids profiles. Three selected accessions (UT121001, KKU-WX112087, and KKU-WX212001) had higher values of total carotenoids, lutein, zeaxanthin, and beta-carotene than those of all check varieties. High and positive correlations among second-emerged ears, marketable second-emerged ears, and total ear number indicate that a higher chance of secondary ears becomes marketable ears with an increase of total ears per plant per hectare. Lutein and zeaxanthin had positive, strong correlations with total carotenoids. The implications and breeding strategies are discussed prior to promoting yellow small-ear waxy corn as a biofortified crop.
