(1) Background: Wood decay is a serious issue that results from the presence of wood-destroying fungi and has a great influence on the international wood industry. The utilization of biological control methods offers good prospects for wood preservation. (2) Methods: The plate-screening experiment, the soil block test of the Chinese stand method (GB/T 13942.1), and the characterization of wood blocks were used to achieve biological control of brown rot and white rot. (3) Results: Through isolation, screening, and identification, the antagonistic bacterium Bacillus velezensis Nhw-B72 strain was obtained. In the plate-screening experiment, the inhibition zone diameter of Nhw-B72 for Gloeophyllum trabeum was 1.68 cm and that for Coriolus versicolor was 2.33 cm. After inhibition, the morphology of mycelia was distorted, malformed, and broken. In the soil block test, the average weight loss percentage of wood blocks in the control group was 61.66%. In the treatment group, the average weight loss percentage of the wood blocks with drying was 28.18% and that of the wood blocks without drying was 34.97%. (4) Conclusions: The strain has an obvious antagonistic effect on the wood-destroying fungi and the sterile fermentative liquid can effectively inhibit wood decay. In addition, compared to the drying of wood blocks, the air-drying of blocks after impregnation with the fermentative liquid had a better inhibition effect.

83 Background: Weight loss during chemotherapy is a significant prognostic factor for poor survival in patients advanced gastric cancer (AGC). However, in most studies, weight loss was measured at the end of chemotherapy, limiting its clinical use. In this study, we evaluated whether weight loss during the first month of chemotherapy could predict survival outcomes in patients with AGC. Methods: We analyzed 719 patients with metastatic or recurrent AGC who were receiving palliative chemotherapy. We calculated initial body mass index (BMIi), percent weight loss after one month of chemotherapy (ΔW1m), percent weight loss after last administration of chemotherapy (ΔWend), and average weight loss per month during chemotherapy (ΔW/m). We correlated these data with overall survival (OS) by receiver operating characteristic (ROC) curves and Kaplan-Meier curves, and performed a subgroup analysis using Cox regression. Results: The probabilities of longer OS had stronger correlations with ΔW/m and ΔW1m than with ΔWend or BMIi. The optimal cutoff values of ΔW/m and ΔW1m for predicting shorter survival were 1% and 3%, respectively. A significant positive correlation between ΔW1m and ΔW/m (r2 = 0.591, p < 0.001) was observed. Patients with ΔW1m more than 3% significantly younger, had worse performance status, more diffuse-type Lauren classification, more HER2-negative pathology, a higher number of involved organs, and more peritoneal seeding at initial presentation. OS of patients with ΔW1m more than 3% were significantly shorter than patients with less weight loss (ΔW1m ≥3%: 9.7, <3%: 16.3 months, p < 0.001). Patients who recovered average weight loss per month after experiencing weight loss at the first month showed prolonged OS compared with patients who did not recovered (ΔW/m < 1%: 21.3, ≥1%: 7.8 months, p < 0.001). Subgroup analysis revealed ΔW1m accompanied poor survival irrespective of other clinical characteristics. Multivariate analysis showed weight loss at the first month of chemotherapy adversely affected OS (p= 0.038). Conclusions: Weight loss at the very first month of palliative chemotherapy could predict unfavorable survival outcomes in AGC.

Studies were conducted to determine the most suitable conditions for the lye-peeling of fresh yam, Dioscorea alata, of the Florido variety. Good peeling resulted from each of these boiling lye solution combinations: 5 minutes in 10-percent, 4 minutes in 15-percent, or 3 minutes in 20-percent. The average weight loss resulting from these three combinations was approximately the same, but less in each instance than when the tubers were hand-peeled. Changes in titrable acidity and hardness values of the tubers were approximately equal to those which resulted from hand-peeled yam. The sensory evaluation of the samples showed no significant difference between hand- and lye-peeled tubers. The lye-peeling method was not wholly satisfactory when the yams had been in storage for more than 3 weeks.

112 Background: Maintaining a healthy weight after breast cancer diagnosis has been associated with improved survival outcomes. Lifestyle interventions are particularly important in overweight women who are at an increased risk of overall and breast-cancer specific death compared to non-overweight women. The purpose of this study is to examine the barriers and acceptance of a lifestyle intervention program among overweight women with newly diagnosed breast cancer. Methods: The Breast Cancer Database of NYU Langone Medical Center was queried for women who were newly diagnosed with breast cancer and who had a body mass index (BMI) ≥25kg/m2. Eligible patients participated in the Moving for Life (MFL) exercise program for 16 sessions. Questionnaires were administered at baseline and at the end of the intervention. Descriptive statistics were used to summarize patient characteristics and paired t-tests were used to see if there were any significant differences before and after the intervention. Results: A total of 40 women were eligible to participate in the MFL exercise program. A total of 20 women declined to participate due to location, transportation limitations, and conflicts in schedule. Of the 18 women who enrolled in the MFL program, 13 (72%) were regular attendees and completed the study. The median age was 61 years (range: 38-76) and the average baseline BMI was 31kg/m2(range: 25-42). After completing the MFL intervention, there was a significant decrease in weight and BMI (p=0.04). The average weight loss was 10lbs. Participants also reported a greater enjoyment of exercise (p=0.02), as well as a decrease in pain related to treatment (p=0.05). Conclusions: Moving for Life is a unique exercise program for breast cancer patients and had a high rate of acceptance and completion in a cohort of overweight breast cancer patients. This study resulted in a statistically significant average weight loss of 10lbs, as well as a greater enjoyment of exercise and decrease in treatment-related pain which may impact long-term lifestyle changes. Longitudinal follow-up at 6- and 12-months will allow assessment of secondary endpoints, including exercise frequency and attitudes about exercise, allowing us to examine sustainability and changes in behaviors and attitudes over time.

ocids are commonly found to be a persistent pest in structures of grain stores. Grain residues are potential pest reservoirs that serve as sources of grain re-infestation. Weight losses caused by psocids on broken wheat kernels were measured. Average weight loss of grain samples was 9.7% after 3 months of Liposcelis bostrychophila infestation. The weight losses were positively correlated with progeny production.

Background Patients with gastrointestinal cancers often suffer from malnutrition and cachexia caused by inflammatory processes due to malignancy and therapeutic intervention. Evaluation of nutritional status and well-being of patients is essential to prevent or slow down the progression of cachexia. In addition, acupuncture as a complementary intervention may help reduce cachexia and unintentional weight loss. Methods Seven patients with cancers of the gastrointestinal tract enrolled in this pilot study were provided with eight acupuncture sessions in addition to their regular treatment schedule. Bioelectrical impedance analysis (BIA) measurements were taken at every other acupuncture session to evaluate the body composition of patients. BIA is a fast, inexpensive and non-invasive method for evaluating fluid, fat and muscle mass distribution which correlates with nutritional status. Results All patients enrolled in the pilot study completed the acupuncture intervention and BIA measurements. The average weight loss and reduction in body weight was 1.3%, which is less than the average weight loss of 5% reported in the literature. Both phase angle and fat-free mass decreased in patients, indicating a worsening of the condition. However, a shift from intracellular to extracellular fluid was not observed, which is usually associated with a loss of cell integrity. Conclusions This pilot study indicates that patients tolerate acupuncture treatments well. The BIA results should be interpreted with caution due to the small sample size. A larger randomised placebo-controlled study is currently being conducted to further investigate the influence of acupuncture and to provide insights into BIA as a reliable tool for evaluating body composition in patients with gastrointestinal cancers.

The purpose of this research was to improve the weight-loss percentage of PVC artificial leather products manufactured by the calendering process. It was noticed that the weight-loss percentage was greater than 5% which did not pass the specification given by the Original Equipment Manufacturer (OEM). Hence, the DMAIC Six Sigma methodology was applied to improve the situation. The cause-and-effect matrix and the Failure Mode and Effect Analysis (FMEA) were adopted to identify the potential factors that affect the quality of the products. After that, the design of experiment (DOE) was used to determine significant factors and optimal parameter settings for the production process to prevent a recurrence. The result shown that the average weight-loss percentage was reduced to only 0.9% after applying new parameter settings.

Gases extracted from wetwood of unwounded black cottonwood (Populustrichocarpa Torrey and Gray) trunks near Vancouver, B.C., throughout 1974 contained less than 0.10% O2 for periods of 5 to 19 weeks during the summer, and an average of approximately 2.5% O2 in winter. CO2 ranged from an average of about 8.5% in summer to about 6% in winter. Decay tests using surface and completely sterilized cottonwood sapwood and wetwood blocks showed no significant weight loss (average 0.2%) after 10 weeks under near-anaerobic conditions (O2 at 0.08%), while parallel tests under aerobic conditions resulted in 42% average weight loss. Both test fungi (Polyporusdelectans Peck and Ganodermaapplanatum (Pers.) Pat.) survived 10 weeks under near-anaerobic conditions, but resumption of decay following this period was considerably delayed. It is suggested that in black cottonwood, wetwood is not necessarily a deleterious phenomenon but rather a condition that imparts considerable decay resistance to the inner wood of unwounded trees.

The aim of the present study was focused on analysis of reproductive traits in the painted stork (Mycteria leucocephala). The analysis of partial reproductive traits was intended to complete the knowledge necessary for ensuring reproduction of the painted stork in captivity on the required level. The observation was performed in the Zoo Zlín – Lešná from 2011 to 2014. The eggs were measured and weighed after laying and then in several‑day intervals. Other observed traits were hatchability of the eggs, number of raised young birds and their weight after hatching. During whole observation period, a total of 90 eggs of the painted stork were evaluated from 12 parental pairs. The average share of fertilized eggs was 38.9 %. Average length of eggs was 68.57 mm, average width was 46.43 mm and average weight was 79.79 g. Average weight loss of eggs during their incubation was 9.87 g. Average hatchability of all the laid eggs was 27.8 %. Average hatchability of the fertilized eggs was 71.4 %. A total of 23 young painted storks were hatched during the observation period. Their average hatching weight was 57.04 g. The overall number of 11 individuals were raised during the four years of observation.

Block Test

A modified soil-block test was used to compare the bark-decomposing ability of various soil- and root-inhabiting fungi. Bark of Pinus taeda was highly resistant to decomposition by all 31 fungi tested. A brown-rot fungus, Lenzites saepiaria, caused the most weight loss, but weight losses due to decay by all fungi varied only from 3 to 15%. Isolates of Mucorales produced 3–8% weight losses from stem bark in 12 weeks. Available nutrients were used within 6 weeks; longer incubation resulted in little additional decomposition. Losses in weight from root bark and stem bark were similar, indicating little nutritional difference between these two substrates.Extraction of stem bark with ethanol or water before incubation with Fomes annosus, L. saepiaria, or Scytalidinun lignicola did not increase the amount of decomposition. This suggests that extractives in the bark may not be responsible for the slow rate of decay. Since autoclaving of the bark before incubation with the fungi enabled the fungi to cause more weight loss than did gas sterilization of the bark, the primary reason for the slow rate of decomposition by fungi is considered to be the complex molecular structure of the bark constituents.
