Background: Diabetes mellitus (DM) challenges health and quality of life of patients, families, and communities. Patients with comorbid depression are more likely to develop macrovascular and microvascular complications. The aim was to assess glycemic control and adherence in diabetic patients with comorbid depression. Further, the study evaluated the relationship between adherence and the physician-patient relationship. Methods: The study was conducted at Al-Agouza Family Medicine Center (AFMC) between February 2018 and March 2020. The included patients were between 35 - 80 years of age;had type 2 diabetes with hemoglobin A1c (HbA1c) ≥ 6.5%, fasting plasma glucose ≥ 126 mg/dl, and scored between 11 - 30 on the Beck Depression Inventory (BDI). Logistic regression, chi-square, and analysis of variance (ANOVA) were used to assess the relationship between depression, adherence, physician-patient relationship, and other variables. Results: The study included 100 eligible patients with a median BDI score of 20 (10 - 30). The median diabetic panel for patients was FBS 188 (126 - 348) mg/dl, PPS 282.50 (162 - 448) mg/dl, and HbA1c 9.5 (6.6 - 14.0)%. Depression and regular follow-up visits were statistically associated with improvement of diabetes symptoms (p = 0.019). There was a significant relationship (p 0.001) between adherence, regular follow-up visits, and knowledge of DM. Further, there was a significant relationship between the physician-patient relationship and DM improvement (p = 0.047). Conclusion: Physician-patient relationship was paramount to improving adherence and positive diabetes care. Our findings suggest a shift to a physician-patient relationship model with mutual agreement on medical decisions is highly recommended. 展开更多

This study aims to compare the quality of family and social relationships and Type D personality in cardiovascular patients with normal people. In this research, 300 individuals (n = 150 male, 150 female) are divided in two groups of patient (n = 150) and non-patients (n = 150) were selected as samples from the author’s offices (both private and his office in Mazandaran Heart Center). They attended in this study filling the questionnaires of “Pierce Quality relations” and “Personality Inventory (DS14)”. In order to analyze data, First observations were described by the help of descriptive statistics methods including tables, graphs, and indices of central tendency and distribution. Then, observations were described by inferential statistics methods such as univariate and multivariate analysis of variance and then were analyzed by SPSS. Out of the 300 participants, 108 patients (36%) had the mean age of 52 to 63 years old and 30 patients (10%) were 30 to 40 years old. This study showed that there is a significant difference between cardiovascular patients and control group in terms of quality of family and social relationships and Type D personality (P < 0.01). Cardiovascular patients have lower quality of family and social relationships, social support, as well as lower depth of relationships, and also higher relationship conflict than normal people. Also cardiovascular patients have higher type D personality than normal people (P < 0.01). In general, research findings indicate the importance of psychological factors associated with coronary artery disease. 展开更多

The relationship between free cancer cells and the pathological characteristics of gastric cancer were studied. Of 100 cases of gastric cancer, free cancer cells in the peritoneal cavity were detected in 32 cases (32%). Free cancer cells were most often found in tendonoid (62.2%) and colour diffused (60.0%) serosal types. When the area of serosal invasion was over 20 cm, the positive free cancer cell rate was 56.6% and only 2.5% if below 20 cm. Free cancer cells were related to the depth of cancer infiltration, often found in the S2 and S3 invasion layers, as well as to the pathological characteristics of gastric cancer. Free cancer cells were often seen in infiltrated type cancer, histologically poorly differentiated or undifferentiated adenocarcinoma. and nest or diffused growth types. In patients without peritoneal metastasis (P0), the positive rate was 26.1%. This study proved that Chen's serosal classification is correct and useful in assessing whether the cancer cells have penetrated through the serosa or not during surgery. Different treatments should be used in the cases with different serosal types. In addition to surgery, destruction of free cancer cells should be considered in tendonoid and colour diffused serosal types, so as to prevent peritoneal metastasis. 展开更多

In a study on erythrocyte polyamine levels in 20 leukemia patients and 18 healthy individuals, following results were obtained. Putrescine(Pu) in ery-throcytes was nearly undetectable but in 2 AMoL patients; Spermidine(Spd) level in ALL was higher than the control volue (P<0.05), in AML (M1, M2) and APL the Spd level was in the range of control group (P>0.1), while that in AMoL and AMMoL was considerably lower as compared to control (P< 0.001); Spermine (Spm) level in all types of leukemia was increased (P<0.001); Spd/Spm ratio was significantly decreased, showing 1.525 in control group, 0.938 in ALL (P<0.025), 0.779 in AML (M1, M2) P< 0.01), 0.319 in APL (P<0.001) and 0.296 in AMoL & AMMoL (P<0.001), and the differences between the Spd/Spm ratio in AMoL and AMMoL and in ALL were noted (P<0.05). These results suggested that determination of erythrocyte polyamines in leukemia patients may be helpful in diagnosis, differential diagnosis and prognosis. 展开更多

Two recombinant inbred line (RIL) populations, one derived from a cross between Zhongyouzao 8 (indica) and Toyonishiki (japonica) and the other from a cross between Qishanzhan (indica) and Akihikari (japonica), were grown in Liaoning and Sichuan Provinces, China, to study the panicle type index (PTI, the ratio of a number of node position on panicle axis where the secondary branch with the most numerous secondary branch grains is located to the number of primary branches) and its relationships with subspecies characteristics and yield traits. With continuous distribution of PTI and numerous of lines with different PTIs in the progenies, indica-japonica hybridization could be a method for breeding cultivars with ideal panicle type. PTI was significantly influenced by environments, with a significant decrease from Liaoning to Sichuan A significantly negative correlation was found between PTI and most of subspecies characteristics. PTI varied remarkably with different subspecies types. As a whole, it showed a trend of indica (H)〉indicalinous (H')〉japonicalinous (K')〉japonica (K) However, it is not appropriate to regard PTI as a parameter for subspecies classification in rice because it was recombined in the filial generations of cross between indica and japonica rice. The negative correlations were found between PTI and most of panicle characteristics, as well as yield-related traits. Based on PTI, most of lines from the two populations were middle dominant panicle type (the number of grains on the secondary branch is numerous in middle position of the panicle) and lower dominant panicle type (the number of grains on the secondary branch is numerous in lower position of the panicle and becomes less towards the top of panicle) with significant yield advantages. 展开更多

A review of the art state was developed about the inflow relationships and their application for reservoir characterization. The theoretical development of the methodology for determining the damage effect using type-curves of the inflow relationships was shown. We show the process followed for achieve the geothermal type-curve affected with damage for reservoirs with mean salinities of 30000 ppm and temperatures up to 350℃. This type-curve was applied using measurement production data in a Mexican geothermal field. According with the obtained results is shown that the methodology for determining the damage effect using production measurements is a sure alternative for the damage effect calculation. It was used an alternative methodology in order to validate the damage presence and the obtained results were consistent.

Since oil palm (Elaeis guineensis Jacq.) does not breed true, tissue culture-derived material is the resource of choice for achieving oil palm homogeneity in terms of growth and yield. Currently, no genomic tagging method is available with which one could verify the ortet (tissue donor oil palm) from which the clonal planting material (ramets) origi-nated, particularly in cases of unsatisfactory performance. Thus, Sime Darby Plantation used 10 genomic microsatellite markers to genotype 8 sets of 5 ramets +1 ortet and 2 single ortets. The average genetic distance (D) among oil palms from the same set of ramets and ortet was 0.0000 with the exception of sets containing off-type ramets (D = [0.0834 - 0.1505]). The dendrogram showed that the ramets and their ortet of origin formed a sub-cluster, confirming their simi-larity. The 10 microsatellite markers were valuable to Sime Darby as tools for verification of ramet-to-ortet relation-ships and for the identification of off-types. Furthermore, the set of 10 markers revealed a high expected heterozygosity (He = 0.634) that is a high expected heterosis effect on which yield depends. 展开更多
