Abstract:

Aim. To increase the effectiveness of treatment and prevention of periodontal diseases in smoking students. Methods. A comprehensive dental examination and survey was conducted among 380 students 180 of whom were smokers, and the other 200 students were not tobacco smokers. The students were comparable by age (mean age 21.1±0.09 and 21.4±0.10 years, p=0.1009) and the initial state of the oral cavity. To assess the effectiveness of treatment and preventive measures, smoking students with inflammatory changes in periodontium were divided into the groups. The first group (52 subjects) was divided into three subgroups: 1a (n=15) — removal of plaque by the piezoelectric ultrasound apparatus Vector; 2a (n=20) — use of the Air-Flo C2 air-abrasive apparatus; 3a (n=17) — use of Gracey curette. The second group (n=32) was divided into two subgroups: control (n=15) where only conventional therapy was applied, including professional oral hygiene (removal of supra- and subgingival dental deposits) and the main one (n=17), where, unlike the control group, additional supportive therapy was introduced with Antitobacco Chamomile-Sage conditioner. Repeated clinical examinations were carried out 1 and 6 months after the completion of treatment using periodontal and hygienic indices. Results. Students were found to have caries and periodontal inflammation but it was more pronounced in patients with a bad smoking habit in history: 4.37±0.12 and 3.98±0.09 — the intensity of caries in smokers and non-smokers, respectively (p <0.05). Among the smoking students in relatively rare cases a healthy periodontium was detected: 2.78±1.22, versus 9.0±2.02 in the group of non-smoking students (p <0.05). With the inclusion of Antitobacco Chamomile-Sage conditioner in the complex therapy, the values of OHI-S and papillary marginal attachment indices were significantly lower than in the control group 1 and 6 months after treatment. A comparative analysis of the data obtained in another treatment group, divided into three subgroups, revealed that with the use of Gracey curette a more pronounced positive shift in the indices was observed. Conclusion. Favorable dynamics in the reduction of hygienic and periodontal indices at all stages of the research, indicating improvement of oral hygiene and periodontal condition, was recorded when using periodontal Gracey curette and “Antitobacco Chamomile-Sage” herbal conditioner in the complex treatment.

Abstract. Recombinant IGF-I was infused sc at a dose of 20 μg · kg−1 · h−1 to 2 healthy subjects during a total of 79 h. Serum levels of IGF-I rose from 93 and 177 to 502 and 616 μg/l, respectively. Fasting blood glucose remained normal. During the infusion, glomerular filtration rate increased by 31% in subject No. 1 and by 32% in subject No.2. Concomitantly, renal plasma flow increased by 26% and 22%, respectively. Proximal and distal tubular reabsorption of fluid and sodium as determined by lithium clearance was elevated to a similar extent. When determined again one week after the end of the IGF-I infusion, all parameters of renal function had returned to baseline. Sodium excretion, body weight and blood pressure did not change. We conclude that IGF-I infused at pharmacological doses has marked effects on kidney function. Future studies will be necessary to define the clinical potential of recombinant IGF-I in the treatment of diseases characterized by impaired renal perfusion and filtration.

Abstract:

Abstract Background and study aims Conventional detection of aberrant crypt foci (ACF) with dye-spraying and magnifying observation is labor- and skill-intensive. We performed a prospective non-inferiority study to investigate the utility of image-enhanced endoscopy (IEE) for detection of ACF. Patients and methods Patients with a history of colorectal neoplasm were eligible. The number of ACF in the lower rectum was counted first using IEE magnification with narrow-band imaging (NBI) or blue-laser imaging (BLI), and subsequently using the methylene blue method. The primary endpoint was the ACF detection rate with IEE, i. e., the number of ACF detected with IEE relative to the number of ACF detected with methylene blue. The secondary endpoints were bowel preparation time, ACF detection time, and the detection rate with NBI or BLI. Results A total of 40 patients were enrolled (NBI 20 and BLI 20). The overall detection rate for ACF with IEE was 81.7 % (503/616; 95 %CI 78.8 – 84.6 %), meeting the primary endpoint. The detection rate for ACF with BLI (84.9 %, 258/304) was significantly higher than with NBI (78.5 %, 245/312; P < 0.05). Both bowel preparation time and ACF detection time were significantly shorter with IEE versus the methylene blue method (P < 0.01, respectively). The detection rates for dysplastic and non-dysplastic ACF with IEE were 84.4 % (27/32) and 80.3 % (469/584), respectively. Conclusion IEE is able to detect ACF during colonoscopy with sensitivity non-inferior to that of the conventional methylene blue method. IEE is simpler than the methylene blue method and is therefore a potentially useful new tool for ACF detection.

Abstract:

Abstract Introduction: Approximately twenty percent of patients with Hodgkin’s lymphoma (HL) relapse or have primary refractory disease. About 50% of these patients achieve long-term remissions after high-dose chemoradiotherapy and autologous stem cell transplantation (HDT/ASCT). At MSKCC, ICE (ifosfamide, carboplatin, etoposide) was incorporated as second-line chemotherapy prior to HDT/ASCT in a comprehensive treatment program. In addition to chemosensitive disease, a clinical prognostic model that emerged from this study identified 3 risk factors - B symptoms at relapse, extranodal disease, and complete remission duration of less than 1 year (Blood. 2001 Feb 1;97(3):616–23). This model was used to intensify treatment according to the number of risk factors, with stratification overcoming the significance of poor prognostic features (Blood. 2003 Nov 16;102(11), abstract #403). Methods: To further identify important prognostic factors, we evaluated pre-ICE biopsy specimens of patients enrolled on one of 3 IRB-approved clinical trials of HDT/ASCT. Prior studies showed that overexpression of bcl-2 and p53 have negative impact on outcome with primary therapy. We sought to determine if our comprehensive second-line program could overcome these poor prognostic features. We performed immunohistochemistry staining for bcl-2, bim (a bcl-2 family marker), and p53; samples were considered positive if any Reed-Sternberg (RS) cells stained for bcl-2 or bim, and if more than 50% stained for p53, at any staining intensity. Results: Seventy one patients had sufficient tissue available. Thirty five patients (49%) had disease progression and 28 (39%) died. Median PFS was 4.8 years, median OS was not reached, and median follow-up was 5.7 years. Bcl-2 was overexpressed in 19(27%), bim in 22 (32%), and p53 in 20 (29%) patients. Expression of bcl-2, bim, or p53 had no significant association with PFS or OS. Five-year PFS rates for positive vs. negative cases were 52.6% vs 50% for bcl-2, 54.5% vs 50% for bim, and 50% vs 51% for p53 (all p=NS). The 3 factor clinical model (B symptoms at relapse, extranodal disease and complete remission duration of less than 1 year) remained highly significant (0/1 vs 2/3 factors) for PFS and OS (p=0.002 and p=0.0003, respectively). Conclusion: Despite the evidence that p53 and bcl-2 overexpression may predict a worse prognosis with initial treatment, it appears that the approach of incorporating ICE and HDT/ASCT may overcome the significance of these biological markers at relapse. Further studies will focus on other pathways that are thought to play a role in relapsed/refractory HL outcomes. Bim is a novel pro-apoptotic marker from the bcl-2 family that is expressed on RS cells and suggests a role in the pathogenesis of HL. Future studies will focus on its role in both initial and relapsed/refractory setting.

Abstract:

BACKGROUND It is estimated that 8110 persons will be diagnosed with Hodgkin Lymphoma (HL) in the US during 2019, but the advent of new treatment options has increased the cure rate to at least 80%. It has been reported that the rates of HL are lower in the adolescent and young adult (AYA) Hispanic population but significantly higher in the Hispanic population older than 65. The relative survival estimates are stated to be similar between AYA Hispanics (HI) and non-Hispanics (NH) but for ages 65-84, HI have a significantly higher mortality rate. Pediatric studies have suggested that ethnicity plays a role in outcomes in patients with HL but there is limited data in the adult population. There is an unmet need in the field, where dossiers on underrepresented ethnic minorities need to be carefully considered and compared to existing data. Therefore, our study aims to compare survival outcomes in Hispanics vs Non-Hispanics with HL, who were treated at the only NCI designated cancer center of South Texas. To our knowledge this is the largest cohort of HL patients from a single academic institution that serves primarily Hispanics. METHODS We located and retrospectively analyzed a total of 616 patients with diagnosis of Lymphoma (HL and NHL) by International Classification of Diseases (ICD) codes and identified 116 cases of HL; all the patients received care at UT Health San Antonio, between 2008-2018. Key variables for each patient included age, gender, race/ethnicity, comorbidities, insurance status, stage, BM and extranodal involvement, treatment received, outcome at 3 and 5 years and vitality status in 2018. Continuously distributed outcomes were summarized with the mean and standard deviation and categorical outcomes were summarized with frequencies and percentages. The significance of variation in the mean with disease category was assessed with one way ANOVA and the significance of associations between categorical outcomes was assessed with Pearson's Chi Square or Fisher's Exact test as appropriate. Multivariate logistic regression was used to model binary outcomes in terms of covariates and indicators of disease. All statistical testing was two-sided with a significance level of 5%. R1 was used throughout. The study was approved by the local Institutional Review Board. The findings will be available to patients, funders and medical community through traditional publishing and social media. RESULTS We identified 116 patients with HL, of which 73 were HI (63%), 43 NH (36%) and 1 not specified (1%). In regard to race, 92% identified as Caucasian, 4% as African American, 3% other and 1% Asian. The median age at diagnosis was 37.4, (SD 15.13). There were 49 females (42%) and 67 males (58%). The most common funding source was commercial insurance N=54 (47%), followed by a hospital payment plan N=30 (26%), Medicare N=16 (14%), unfunded N=13 (11%) and Medicaid N=3 (2%). Most prevalent co-morbidities were HTN N=28 (24%) and diabetes mellitus N= 23(20%); 50% of patients had no co-morbidities (N=63).At diagnosis ECOG of 0-1 was seen in 108 patients (93%); 8 were Stage I (7%), 39 stage II (33%), 32 stage III (28%), and 37 stage IV (32%). EBV was positive in 26 patients (22%). There were 15 patients that were HIV positive (13%), 54% with CD4 count <200, and 12 (75%) on antiretroviral therapy at diagnosis. Median PFS was 853.85 days (SD 912.92). We excluded patients who were lost to follow up or had not reached 3/5 years. At 3 year follow up there was: complete response in 37 HI (74%) vs 22 NH (92%); disease progression in 8 (16%) vs 0 (0%); death in 5 (10%) vs 2 (8%), respectively (p-value= 0.094). At 5 year follow up there was: complete response in 30 HI (77%) vs 17 NH (90%); progressive disease in 2 (5%) vs 0 (0); death 7 (18%) vs 2 (11%), respectively (p-value = 0.619). At the end of 2018, 41 HI (84%) were alive compared to 22 NH (88%) [p-value 0.74]. CONCLUSION Within the limitations of sample size, our study demonstrates that in the prevalently Hispanic population of our institution, HI patients with HL have no statistically significant difference in outcome when compared to NH patients. Disclosures No relevant conflicts of interest to declare.

Abstract:

120 Background: Despite treatment advances, metastatic castrate resistant prostate cancer (mCRPC) remains a lethal disease. Trials in 177LuPSMA-617 have demonstrated good efficacy and safety, but synergistic combinations may further improve treatment responses. NOX66 inhibits external NADH oxidase type 2 with downstream pro-apoptotic actions including radio-sensitization. We present results of a prospective open label single arm phase 1/2 dose escalation/expansion trial of 177LuPSMA-617 and NOX66 in mCRPC. Methods: Men with progressive mCRPC post androgen signalling inhibition (ASI) and taxane chemotherapy were eligible. Inclusion criteria included PSMA PET/CT intensity > SUV max 15, with no discordant disease on FDG PET/CT, Hb > 100 g/L, Platelets > 90 x 106/L and GFR > 40 mL/min. Protocol allowed up to 6 doses of 177 Lu-PSMA 617 (7.5Gbq) on day 1 with NOX66 (suppository) given day 1-10 at 6-weekly intervals; the first 8 men received 400mg NOX66. After safety review, dose was escalated to 800mg. Data regarding safety, efficacy, pain scores, and QOL were collected. Results: 32/43 (26% imaging screen failures) screened men were enrolled (November 2017 – June 2019), of whom 100% had prior docetaxel and ASI, and 94% (30/32) cabazitaxel. All men received ≥ 2 cycles, with 12/32 completing 6 cycles, and 16/32 2 - 5 cycles, while 4/32 remain on treatment. Any PSA response was seen in 84% (27/32), with a PSA response > 50% in 62.5% (20/32). Median PSA PFS was 6.5 months (95%CI 3.54-9.3). To date, 72% (23/32) of patients have progressed. 34% (11/32) men have died with median OS not reached. 50% (12/24) of men with baseline pain scores ≥3 (24/32) had significant reduction in pain. Adverse events are summarized below. Conclusions: Combination 177LuPSMA-617 with NOX66 appears safe and efficacious in men with heavily pre-treated mCRPC.

Abstract:

Gray mold (Botrytis cinerea Pers.) is a major disease of grapevine (Vitis vinifera L.) worldwide. Integrated control strategies, including canopy management and fungicide treatments, are needed to control gray mold. Chemical control relies on the use of single mode of action fungicides. The aim of this research was to study the sensitivity of B. cinerea to boscalid, which is a single mode of action fungicide of the succinate dehydrogenase inhibitor (SDHI) fungicide group. Fifty isolates were obtained in 2012 to 2013 from commercial vineyards in central Chile. Vineyards had received two boscalid applications at least for four consecutive years. Briefly, the percent mycelial growth inhibition (MGI) was determined on minimal medium (MM) (2) plus 50 μg m−1 of boscalid (Cantus 50 WP, BASF Chile). Each isolate was tested in triplicate, obtaining 2% highly resistant (HR, MGI ≤25%), 32% moderately resistant (MR, MGI 26 to 50%), 64% low resistant (LR, MGI 51 to 80%), and 2% sensitive (S, MGI ≥81%) phenotypes. Nine isolates were arbitrary selected and compared for MGI on MM plus 50 μg ml−1 of boscalid (1) and conidial germination inhibition (CGI) on yeast extract-bacto peptone-Na acetate (YBA) plus 5 μg ml−1 of boscalid (2,3). Isolates previously determined to be S and HR had the same phenotype for both MGI and CGI. However, all of the MR and LR isolates, determined based on the MGI tests, were identified as S isolates in the CGI tests. Using primer-introduced restriction analysis (PIRA)-PCR (4), the SdhB mutations were detected only in the HR isolate. The amplifications were performed with H272L-fw/H272-rev and were digested by the enzyme BglII, yielding 35- and 85-bp fragments and confirming a mutation at codon 272 (H272L) in the HR phenotype. The efficacy of the label-rate (0.4 g liter−1) boscalid in controlling gray mold was determined on ‘Granny Smith’ apples. The apples were surface-disinfested (75% ethanol, 30 s), wounded with a sterile syringe, and inoculated with a mycelium plug (5 mm in diameter) or 20 μl of a conidial suspension (106 conidia/ml) of one HR, MR, and S isolate. The inoculum was placed on the wounded sites after boscalid application. Apples were incubated for 7 days at 21°C. Each test had four replicates and the experiment was conducted three times. Boscalid slightly controlled (<6.7% efficacy) gray mold on the apples that were inoculated with mycelium or conidia of the HR phenotype isolate, while the sensitive isolate was highly controlled (>95% efficacy), and the MR isolate was moderately controlled (27 to 34% efficacy). These results demonstrate that mycelium or conidia assays using MM + 50 μg ml−1 boscalid or YBA+5 μg ml−1 boscalid consistently detected HR isolates. The S isolates detected using MGI were also S according with the CGI tests. The presence of the boscalid HR strains of B. cinerea associated with the H272L mutation in grapevine in Chile is reported for the first time in this study. This finding suggests that resistance to boscalid needs to be considered in the design of gray mold control strategies in commercial grapevine orchards. References: (1) D.

Abstract:

In der vorliegenden Arbeit wurden die Krankenblätter 366 kleiner Frühgeborener (Schwangerschaftswochen (SSW) 23/0 bis 32/0), die im Zeitraum von 1995 bis 2001 in der Frauenklinik des Klinikums Süd Nürnberg aus Einlingsschwangerschaften geboren wurden, retrospektiv ausgewertet. 136 Schwangere wurden nach einem vorzeitigen Blasensprung entbunden. 16 Kinder sind innerhalb der Neonatalperiode gestorben. Erfasst wurden zum einen wichtige prä- und peripartale Faktoren, u.a. mütterliches Alter und Risiko,Schwangerschaftsalter, Indikation zur Schwangerschaftsbeendigung und Entbindungsmodus, und zum anderen fetale Outcome-Parameter wie Gewicht, Apgar Score, Nabelarterien-pH-Wert, Base Excess und Intubation. Darüber hinaus wurden für jedes Kind die Morbiditätsdiagnosen und bei gestorbenen Kindern die Todesursachen aufgenommen. In 37 % der Fälle lag der Frühgeburt ein vorzeitiger Blasensprung zugrunde, in 31 % eine vorzeitige Wehentätigkeit. Die übrigen 32 % wurden durch maternofetale Pathologie hervorgerufen. Das Gewicht der Frühgeborenen lag zu 75 % unter 1500 g. In einer schweren Azidose befanden sich 6 % der Kinder. Eine starke Abhängigkeit der Outcome-Parameter von Poleinstellung und Entbindungsmodus war nicht zu beobachten. Frühgeborene nach fetaler Entbindungsindikation wiesen ein schlechteres Outcome auf als nach maternaler Indikation. Von den beobachteten Krankheiten kam das Atemnotsyndrom am häufigsten vor (in 63 % der Fälle), bei 20 % der Kinder III.-IV. Grades. Hochgradige Retinopathie (Grade III-IV) wurde in 5,4 %, retrolentale Fibroplasie in 0,6 % der Fälle diagnostiziert. Ein Drittel der Kinder erkrankten an einer Sepsis. Bei 18 % entwickelte sich im Verlauf eine bronchopulmonale Dysplasie. Schwere Hirnblutungen (III.-IV. Grades) erlitten 4,5 % der Frühgeborenen, periventrikuläre Leukomalazie 3,6 % und nekrotisierende Enterokolitis 1,5 %. Die genannten Krankheiten traten mit zunehmendem Schwangerschaftsalter weniger häufig auf. Die Prognose verbesserte sich besonders stark in den SSW 28-30. 6 von 16 Todesfällen (38 %) entfielen auf die ersten 24 Lebensstunden. Die Todesursachen waren Unreife/Mangelgeburt (31 %), Sepsis (31 %), Fehlbildungen und intrauterine Asphyxie (jeweils 13 %). Die neonatale Mortalitätsrate nahm mit zunehmendem Geburtsgewicht deutlich ab: Von 33 % für Frühgeborene unter 500 g, auf 3 % ab 1000 g. Die mittlere Latenzperiode nach einem vorzeitigen Blasensprung betrug 9,1 Tage (in 90 % der Fälle bis zu 3 Wochen, Maximum: 10 Wochen). Kinder beider betrachteter Gruppen von 23-28 und 29-32 SSW profitierten vom angewendeten konservativen Management: Bezüglich der Lungenreife war eine klare Verbesserung zu beobachten, falls die RDS-Prophylaxe 48 Stunden vor der Geburt abgeschlossen war. Sepsis kam zwar in der Gruppe mit niedrigerem Gestationsalter häufiger vor, war jedoch nicht direkt abhängig von der Latenzperiode. Im Vergleich mit anderen aktuellen Studien lagen die in dieser Arbeit festgestellten Morbiditätsraten etwa gleichauf. Die Kinder des eigenen Kollektivs entwickelten aber seltener intraventrikuläre Hämorrhagie und periventrikuläre Leukomalazie. Die starke Abnahme von Morbidität und Mortalität mit zunehmendem Schwangerschaftsalter wird in den Vergleichsstudien ähnlich berichtet.

Abstract.—Bighead carp Hypophthalmichthys nobilis have become established within the Mississippi River system (MRS) and pose a serious threat to native fishes and aquatic ecosystems throughout North America. Determining their dispersal dynamics will be a key management tool for controlling their expansion. To better understand how bighead carp have spread through the MRS, we developed a simple diffusion model to be used as a heuristic tool to generate insights regarding dispersion patterns. First, we collected occurrence data from fish museums and government agencies spanning more than 30 years of sampling in the MRS and nearby rivers. These were then combined into a geographic information system database and used to create yearly occurrence maps for this species. We then developed a diffusion model for bighead carp using information on their movement and reproduction. The resulting model can be used to track the dispersal of hypothetical carp populations from different points of introduction within the MRS. With this model, we generated and compared four possible dispersal scenarios for bighead carp based on likely points of introduction. For each of these, we calculated Cohen’s kappa and sensitivity (measures of predictive success) to determine which dispersal scenarios were the most accurate in predicting bighead carp occurrence pattern after 30 years. We found significant agreement between the actual and predicted distributions of carp after 30 years of expansion for all four dispersal scenarios (Cohen’s kappa: range = 0.136–0.426, p < 0.05). The single introduction scenario (in the Arkansas River) had the lowest agreement with the occurrence data (Cohen’s kappa = 0.136, sensitivity = 32%) compared with the scenarios representing multiple points of carp introduction: introductions in the Arkansas and Missouri rivers (Cohen’s kappa = 0.370, sensitivity = 71%), introductions in the Arkansas and lower Ohio rivers (Cohen’s kappa = 0.391, sensitivity = 68%), and introductions in all three river locations (Cohen’s kappa = 0.426, sensitivity = 85%). The triple introduction scenario also had the highest sensitivity (sensitivity = 66%) when it was compared to the other three scenarios for accuracy on a year-to-year basis: Arkansas River only (sensitivity = 25%), Arkansas and Missouri rivers (sensitivity = 39%), and Arkansas and lower Ohio rivers (sensitivity = 46%). These results suggest expanding bighead carp populations in the MRS began from multiple origins rather than a single introduction. Other insights derived from the dispersal scenarios include evidence that bighead carp are possibly more widely dispersed than current occurrence data indicate and that the species is likely extending its range “under the radar” of standardized sampling. Finally, we used these dispersal scenarios to predict potential high carp density hot spots that could develop over the next 20 years in the MRS and should be targeted for control management.

Abstract:

Although HHT accounts for approximately one third of the ara-chidonic acid (AA) metabolites produced by stimulated platelets, no well defined function has been attributed to this platelet product. We report that HHT stimulates prostacyclin production by endothelial cells, and have identified the mechanism for this effect. In human umbilical venous endothelial cells HHT (0.5 and 1pM) stimulated prostacyclin (RIA for 6KPGF1α) by 32±10% (1 SE) and 42±13% (P<0.05 and (0.01). Similar changes were observed when the effect of HHT on exogenous [1 -14C] AA metabolism in fetal bovine aortic endothelial cells (FBAECs) was studied. 6KPGF1α was stimulated by 25±9% and 30±6% at HHT cones, of 0.5 and 1μM (P<0.05) . While prelabelling experiments with [1-14c] AA revealed that HHT (1μM) did not affect the ionophore stimulated release of AA from FBAEC membrane lipids (29521±11837 cpm/well control vs 32458+8811 in HHT treated cells, mean ±1SD) kinetic analyses revealed that HHT affected vascular cyclooxygenase. HHT (1μM) increased Vmax in test microsomes (706±21 pmol/mg/min) when compared to controls (529±20; P<0.02). No effect on Km was observed (6.2±0.3μM control vs. 7.2±0.4 in HHT treated microsomes). The effect of HHT on platelet AA metabolism was next studied. Preincubation of washed platelets with HHT (1μM) did not enhance thrombin (0.2 U/ml) induced pit. TXB2 (2.27±1.34 pmol/106 platelets control vs 2.28±1.62 in HHT treated platelets). In platelets prelabelled with [ 1-14c] AA, HHT (1μM) also had no effect on AA release post thrombin stimulation (5794_423 cpm per 108 platelets control vs. 6135±612 for paired HHT treated cells). Conversion to cyclooxygenase metabolites was also not enhanced (2605±265 vs 2806±332 for test platelets). HHT thus stimulates vascular prostacyclin without a concomitant effect on platelet AA metabolism. Our findings may explain the discrepancies relative to prostacyclin production in atherosclerosis and diabetes. In these disorders while ex vivo production of prostacyclin by vascular tissue is decreased, in vivo production is elevated. HHT may also be an important local modulator of platelet plug formation and could play a protective antithrombotic role by its hitherto unrecognized effect on vascular prostacyclin.

Abstract:

"Appropriate self-regulation in motivation and experiencing flow in learning and other academic activities are important factors for success in study and psychological wellbeing. Previous studies suggested that achievement goals have role in student’s motivation for learning, but there is only partial knowledge regarding the role of achievement goals in motivational regulation and academic flow. The aim of this study was to explore: a) the role of achievement goals in motivational self-regulation and study-related flow; b) the incremental role of mastery self-talk motivational strategy in academic flow over the mastery-approach goal; c) the mediating role of mastery self-talk motivational strategy in the relationship between mastery-approach goal and academic flow. It was expected that both mastery-approach goal and mastery self-talk motivational strategy will have positive and incremental role in academic flow, and that the relationship between mastery-approach goal and academic flow would be mediated through using motivational strategy of mastery self-talk. The participants were 113 university undergraduate students studying mathematics (M= 20 years, 61% females). Self-report questionnaires assessing achievement goals, strategies used for self-regulation of motivation, and study-related flow were applied. Data analysis included regression analyses and mediational analyses. Regression analyses revealed that personal goal achievements explained 43% of variance in mastery self-talk strategy, 32% of variance in performance-approach self-talk strategy, 18% of variance in performance-avoidance self-talk strategy, 11% of variance in environmental control strategy, 7% of variance in self-consequating strategy, and 10% of variance in proximal goal strategy. Personal achievement goals explained 45% of variance in academic flow. Mastery-approach goal was predictive for explaining individual variance in most of positive motivational strategies and academic flow. In line with hypothesis, it was found that mastery self-talk mediated the relationship between mastery-approach goal and flow. The results underscore the importance of adopting mastery-approach goal and using mastery self-talk strategy in order to experience study-related flow."

Abstract:

The increasing trend in power levels and associated densities leads to the need of design thermal optimization, either at the module level or at the system (module-board stack-up) level. The wireless communication industry is facing multiple challenges as it tries to promote smaller, faster and cost-effective packages, yet trying to cope with potential thermal bottlenecks. The present study investigates a new family of packages, whose thermal and electrical performances are far superior to the classic (standard) packages. A 3-D conjugate numerical study was conducted to evaluate the thermal performance of Gallium Arsenic (GaAs) die packaged in Quad Flat No Lead (QFN) packages for various wireless and networking applications. Two different QFN packages are investigated: a standard package and a Power package (PQFN) with thicker leadframe and solder die attach. The thermal impact of die attach material, leadframe thickness, die pad size, and board structure is evaluated and provides valuable information for product designers. Two powering scenarios are investigated: 1) one for standard operating parameters and 2) an alternative for extreme operating powering scenarios. Results indicate that the peak temperature reached on the die for 3×3 mm QFN under normal powering conditions is ∼138.5°C (or 119°C/W junction-to-air thermal resistance), while for the extreme scenario, the junction temperature is ∼186°C (or 125°C/W junction-to-air thermal resistance). In both cases, the top Au metal layer has a limited impact on lateral heat spreading. Under extreme powering conditions, the 5×5 mm PQFN package reaches a peak temperature of ∼126°C (66°C/W thermal resistance). A ∼32% reduction in peak temperature is achieved with the 5×5 PQFN package. The improvement is mainly due to the larger package size, high conductivity die attach material, thicker leadframe and more board thermal vias. A parametric study shows that the increase in leadframe thickness from 0.2 mm (8 mils) to 0.5 mm (20 mils) in the QFN package will lead to only 3% reduction in peak temperature. By comparison, for both packages, the die attach material (conductive epoxy vs. solder) will have a significant impact on the overall reduction in peak temperature (∼12%). Experimental measurements using an Infrared (IR) Microscope are performed to validate the numerical results. The results indicate good agreement (∼6% discrepancy) between the numerical model and the measurement.
