Abstract Our purpose was to compare with respect to fecundity and longevity two groups of F1 diploid virgins of Habrobracon the fathers of which had been X-rayed with 3000r. Sorting of wasps into two groups was based on low or high hatchability of their F2 haploid eggs. Wasps with low hatchability (below 60%) are heterozygous for induced embryonic lethals such as recessives and translocations; wasps with high hatchability (100–60%) are free of lethals or possibly heterozygous for mild detrimentals. The F1s showing high hatchability laid significantly more eggs on the average; the average difference in lifespan was almost statistically significant (7% level). A more sensitive analysis by regression indicated a highly significant linear regression of survival of all F1s on hatchability of their eggs: F1s whose eggs showed 100% hatchability lived 1.84 days longer on the average than those whose eggs showed no hatchability. Furthermore, the former laid 4.99 more eggs on the average than the latter. The data also showed a very highly significant positive correlation coefficient between eggs laid and survival of mothers (0.122***) and a very highly significant positive partial correlation coefficient (0.105***) with hatchability held constant. The latter indicates that the F1s which laid more eggs also live longer, regardless of the hatchability of their eggs and hence of the heterozygosity of the mothers for lethals and other detrimentals.

A field experiment conducted for screened 288 elite gen pool of linseed against bud fly infestation at Kanpur, India during rabi 2012-13 to study the bud structure of resistance of linseed against bud fly. The results indicated that the bud length and width showed significant positive correlation coefficient relationship (r=0.1559 and 0.0761) bud infestation. The resistant germplasm line minimum (GS-234) minimum bud length and width (7.93 ×3.26 mm) had relative minimum bud infestation (6.88%) and was statically at par other resistant germplasm lines viz. A-95B, CI-1385, EC-1392, EC-1424, GS-234, IC-15888 and JRF-5. While susceptible germplasm line (Arny) exhibited maximum bud length and width (8.25 ×3. 23 mm) maximum bud infestation(65.11%) which was statically at par with other susceptible lines viz. Ajgan-3-1, Ajgan-20M, Alipur (Hamirpur), Anand, GS-148, GS-440, Gunawal Local, NP(RR)193, RAULD-7810, RLC-28(PM), MS-14, SJKO-2, SJKO-45.

ABSTRACT The present study analyzed the average and minimum streamflow behavior of 11 watersheds located in the Atlantic Forest Biome, relating them to the changes in forest cover. The average minimum flow with seven days of duration (Q7), the average annual flow (Qave), the total annual precipitation (Pa) and the percentage of forest cover (FC) for each watershed were determined. The joint correlation between the FC and the Pa with the flow for each watershed were analyzed by adjusting multiple linear regression equations. The partial correlation coefficient was also used to analyze whether the variation in the FC influenced the water flow when the effects of Pa are fixed. This study allowed us to identify significant associations between FC and Pa with Q7 or Qave in only two of the watersheds. Disregarding the effects of Pa, the increase in the FC tended to result in a reduction in the Qave, and in turn increased the Q7 in these two watersheds.

The purpose of this study is to empirically determine the improvement of teacher's commitment to the organisation by observing its connection with servant leadership of the principal and job satisfaction, with respondents being Permanent Teachers of the Foundation (GTY) of Private Junior High School in Cibinong District, Bogor Regency. The number of research samples of 183 teachers was taken randomly using the proportional random sampling technique. The method used was the correlation method. Hypothesis testing was carried out using parametric statistical analysis in simple and multiple linear regression analysis, simple and multiple correlation analysis, and partial analysis with a significance level of = 0.01 and = 0.05. This study resulted in four conclusions. First, there is a significant positive correlation between servant leadership (X<sub>1</sub>) and teacher's commitment to the organisation (Y), which is indicated by a simple linear regression equation Ŷ = 63.094 + 0,501X<sub>1</sub>. with correlation coefficient r<sub>y1</sub> = 0.73, coefficient of determination R<sub>y1</sub><sup>2</sup> = 0.5361. Second, there is a very significant positive correlation between job satisfaction (X2) and teacher’s commitment to the organization (Y) which is indicated by the linear regression equation Ŷ = 56.35 + 0.552X2 with correlation coefficient r<sub>y2</sub> = 0.66, coefficient of determination R<sub>y2</sub><sup>2</sup> = 0,4343. Third, there is a significant positive correlation between servant leadership and job satisfaction collectively with the teacher's commitment to the organisation, which is indicated by the equation Ŷ = 35.50 + 0.372X1 + 0.34X2 with a correlation coefficient r<sup>y.12</sup> = 0.81 and coefficient of determination R<sub>y.12</sub><sup>2</sup>= 0.665. Fourth, commitment to the organisation of GTY's Private Junior High School in Cibinong District, Bogor Regency can be enhanced through strengthening servant leadership and job satisfaction.

AbstractSeveral cytokines and adipokines are related to clinical severity and progression in knee osteoarthritis. The aim of this study was to evaluate the associations of IL-8 with clinical severity and with local and systemic adipokines and cytokines. This is a Cross-sectional study including 115 women with symptomatic primary knee osteoarthritis with ultrasound-confirmed joint effusion. Age, symptoms duration and body mass index were collected. Radiographic severity was evaluated according to Kellgren–Lawrence. Pain and disability were assessed by Lequesne and Knee injury and Osteoarthritis Outcome Score pain, symptoms and function scales. Three inflammatory markers and five adipokines were measured by ELISA in serum and synovial fluid. Partial correlation coefficient (PCC) and corresponding 95% confidence interval were used to evaluate association. Synovial fluid IL-8 was significantly associated with clinical severity scales. After controlling for potential confounders, associations measured by a Partial Correlation Coefficient (PCC) remained essentially unaltered for Lequesne (PCC = 0.237), KOOS pain (PCC = − 0.201) and KOOS symptoms (PCC = − 0.209), KOOS function (PCC = − 0.185), although the later did not reach statistical significance. Also in synovial fluid samples, associations were found between IL-8 and TNF (PCC = 0.334), IL6 (PCC = 0.461), osteopontin (PCC = 0.575), visfatin (PCC = 0.194) and resistin (PCC = 0.182), although significance was not achieved for the later after statistical control for confounders. None of these associations were detected in serum. In conclusion, IL-8 was associated with clinical severity, inflammatory markers and adipokines in synovial fluid, but not in blood. Although the reported associations are weak to moderate in magnitude, these findings reinforce the notion that local and not systemic inflammation is more relevant to clinical severity in knee OA women with joint effusion.

Abstract. Plasma total T4 (TT4), T3 (TT3), free T4 (FT4), free T3 (FT3), thyroxine binding globulin, hCG, and erythrocyte zinc content were measured in 43 women with uncomplicated pregnancy and in 71 patients admitted with hyperemesis gravidarum. Plasma concentration of thyroid hormones in hyperemesis subjects showed wide variability and 32% of subjects had high TT4 (higher than mean +2 sd of normal pregnant subjects), 33% had high FT4, 20% had high TT3, and 20% had high FT3. Red cell zinc content, a tissue marker of thyroid status, in the hyperthyroxinemic subjects was not different from that of normothyroxinemic hyperemesis subjects or of subjects with uncomplicated pregnancy. The elevated TT4 concentration decreased spontaneously in all but two of the hyperemesis subjects to normal pregnant levels. The plasma FT4 concentration at presentation correlated with plasma hCG in hyperemesis gravidarum (partial correlation coefficient r = 0.411, P< 0.01), but not in normal pregnancy (partial correlation coefficient r = 0.043) after allowing for the effect of gestational age. We conclude that approximately one third of hyperemesis subjects show transient hyperthyroxinemia and suggest that hCG or a molecular variant of hCG may stimulate the thyroid gland.

We intend to develop earphone-type wearable devices to measure occlusal force by measuring ear canal movement using an ear sensor that we developed. The proposed device can measure occlusal force during eating. In this work, we simultaneously measured the ear canal movement (ear sensor value), the surface electromyography (EMG) of the masseter muscle and the occlusal force six times from five subjects as a basic study toward occlusal force meter development. Using the results, we investigated the correlation coefficient between the ear sensor value and the occlusal force, and the partial correlation coefficient between ear sensor values. Additionally, we investigated the average of the partial correlation coefficient and the absolute value of the average for each subject. The absolute value results indicated strong correlation, with correlation coefficients exceeding 0.9514 for all subjects. The subjects showed a lowest partial correlation coefficient of 0.6161 and a highest value of 0.8286. This was also indicative of correlation. We then estimated the occlusal force via a single regression analysis for each subject. Evaluation of the proposed method via the cross-validation method indicated that the root-mean-square error when comparing actual values with estimates for the five subjects ranged from 0.0338 to 0.0969.

772 Background: Oxaliplatin-induced peripheral neuropathy (PN), for which no therapy has been firmly established, is a critical factor that makes the continuation of chemotherapy difficult. Numbness and pain are currently evaluated using subjective methods such as the visual analog scale (VAS). However, because the assessment of pain can greatly vary depending on the mood and physical state of the patient at the time of assessment, it is best to objectively evaluate pain. Therefore, a method for objective assessment is also required to evaluate drugs designed to ameliorate PN. Pain Vision PS-2100 (PV) is an analytical instrument that was designed to quantitatively and objectively assess sense perception and nociception in a patient. Although it is used in the field of anesthesiology, there have been no reports concerning its use for the assessment of oxaliplatin-induced PN. Methods: The present study examined the correlation of subjective and objective assessment results using VAS and PV, respectively, for cases of oxaliplatin-induced PN. Subjects comprised 58 patients with colorectal cancer who underwent chemotherapy at the Fukuoka University. Results: Both VAS and PV assessments of PN were performed 173 times in total, and partial correlation coefficient analysis adjusted by subject and gender. The VAS and PV mean values of PN were 20.5 (0–100) and 27.9 (0–416), respectively. The partial correlation coefficient was 0.258 (p=0.0053). Conclusions: Although both assessments evaluated the same events, no strong correlation was observed between the results and a weak correlation was observed between VAS and PV. These results suggest that because VAS and PV each measure different factors, both subjective and objective assessments of drugs designed to ameliorate oxaliplatin-induced PN are necessary.
