Mulberry (Morus sp.; Moraceae) is a perennial tree crop, which provides sustainable economic and environmental benefits. Its foliage is the only natural feed available for the silkworm Bombyx mori Linneaus for the production of silk. The mulberry germplasm of the Sericulture Research and Development Institute, Don Mariano Marcos Memorial State University (DMMMSU-SRDI), maintains different exotic and indigenous collections. This study aimed to select breeding materials with high propagation traits for crop improvement and to identify suitable parent materials. Pooled data of 2009 and 2010 evaluations on sprouting, rooting and root proliferation rate at 20, 60 and 90DAP, respectively, were subjected to Analysis of Variance. Selection of variety was done using the Least Significant Difference (LSD) using Batac a widely used a variety for cocoon production, as check variety. Result revealed that there was no significant variation among the 32 mulberry collections as to the number and weight of roots and root-shoot ratio by length and weight. Identified parent materials for improved rooting capacity are S3, Papua, King, MA, Collection2 and H4, thus, considered for drought resistance.

Compound Classification

In plant ecology, biochemical analyses of bryophytes and vascular plants are often conducted on dried herbarium specimen as species typically grow in distant and inaccessible locations. Here, we present an automated in silico compound classification framework to annotate metabolites using an untargeted data independent acquisition (DIA)–LC/MS–QToF-sequential windowed acquisition of all theoretical fragment ion mass spectra (SWATH) ecometabolomics analytical method. We perform a comparative investigation of the chemical diversity at the global level and the composition of metabolite families in ten different species of bryophytes using fresh samples collected on-site and dried specimen stored in a herbarium for half a year. Shannon and Pielou’s diversity indices, hierarchical clustering analysis (HCA), sparse partial least squares discriminant analysis (sPLS-DA), distance-based redundancy analysis (dbRDA), ANOVA with post-hoc Tukey honestly significant difference (HSD) test, and the Fisher’s exact test were used to determine differences in the richness and composition of metabolite families, with regard to herbarium conditions, ecological characteristics, and species. We functionally annotated metabolite families to biochemical processes related to the structural integrity of membranes and cell walls (proto-lignin, glycerophospholipids, carbohydrates), chemical defense (polyphenols, steroids), reactive oxygen species (ROS) protection (alkaloids, amino acids, flavonoids), nutrition (nitrogen- and phosphate-containing glycerophospholipids), and photosynthesis. Changes in the composition of metabolite families also explained variance related to ecological functioning like physiological adaptations of bryophytes to dry environments (proteins, peptides, flavonoids, terpenes), light availability (flavonoids, terpenes, carbohydrates), temperature (flavonoids), and biotic interactions (steroids, terpenes). The results from this study allow to construct chemical traits that can be attributed to biogeochemistry, habitat conditions, environmental changes and biotic interactions. Our classification framework accelerates the complex annotation process in metabolomics and can be used to simplify biochemical patterns. We show that compound classification is a powerful tool that allows to explore relationships in both molecular biology by “zooming in” and in ecology by “zooming out”. The insights revealed by our framework allow to construct new research hypotheses and to enable detailed follow-up studies.

Frequency and percentage distribution, weighted arithmetic mean and independent t-test and chi-square are the statistical tools used to answer the entire research question. The data gathered was computed using SPSS analyzed and interpreted with the aide of the statistician. Descriptive survey method was used as the research method. This study utilizes 40 teachers from different colleges/department. Convenience sampling was used to It is the recommended number of which it is the 30% from the total population of all the faculty of Mindanao State University-Sulu.; questionnaire is used by the researcher as a research instrument of the study. The findings of the study were: 1) There is no significant difference of issues and concern of the MSU-Sulu teacher towards modular distance learning approach when grouped according gender but in contrary; and 2) There is significant difference on the issues and concern among MSU-Sulu teacher towards modular distance learning approach when grouped according colleges. The issues encountered towards modular distance learning approach were communication failure like that of instructions or confusion of students on the modules, limited teacher guidance, student’s in discourteous approach to teachers, complaints on not understanding the module, and all of which results to misbehavior on students and failure to pass worksheet on time. In addition, the concerns of the MSU-Sulu teacher towards modular distance learning approach were; first, hidden expenses on modules; second, teacher’s lack of media literacy; third, poor internet connection which intercepts communication between teacher and students; fourth, time constraint among teachers due to overload paperwork; fifth, equipment problem and complexity of the discussion as well as measurement of student’s performance; sixth,  managing student’s responses from time to time; seventh, teacher’s unavailability  and lastly, difficulties of studying among slow learners. Moreover, on teaching preparations on the adaptation of modular distance learning approach, the issues were cater and set time for student’s inquiries and be flexible to allow extension in terms of passing worksheets as well as allow parents, relative or even friends to pass worksheets in their behalf to lessen transportation expenses. Teachers must appreciate/ recognize his/her students to boost their confidence and avoid favouritism while being considerate to students who are attention seeker or may have ADHD. Correspondingly, the concerns were. Teachers must encourage handwritten answers to lessen plagiarism, on the absence of teacher, the parents and elders must guide the students in their learning at home. Teacher and parent’s guidance must go hand and hand in today’s learning. Teachers must likewise be flexible in finding solutions on printing shortage. And lastly, alternative teaching strategies like modular learning should be hone to aid lack of media literacy of both teacher and students In view of the findings and analysis, the following are recommended: Teachers must be flexible with the present kind of teaching strategy at all cost and at all aspects, Set guidelines as to establish proper communication among students and teachers, learning materials must be affordable as well as easy to understand content, teachers must develop their media literacy skills and encourage teachers to be available to their students on allotted time and cater all their inquiries with patience at all times. Furthermore, the following are the recommended research agenda: Teacher’s training on media literacy and module development programs to allow teamwork in the making process.

Ecophysiological studies under semi-controlled conditions in nurseries and greenhouses are essential to enable the use of native species to recover degraded areas and for commercial planting. Talisia subalbens (Mart) Radlk, 'cascudo', is a native fruiting species of the Cerrado on the verge of extinction. The ecophysiological performance of this species was evaluated in nursery conditions under different levels of shading (full sunshine, 30%, 50% and 70%). Initial growth, biomass allocation, gas exchange and chlorophyll content of the plants were analyzed. Full sunshine cultivated plants showed a higher accumulation of total, shoot, and root dry biomass. There was no significant difference in the root/shoot ratio among the treatments. Seedlings cultivated under full sunshine and 30% shading showed higher values for height, basal diameter, and leaf area. Differences in stomata conductance and photosynthesis rate were not observed among the different shading levels. Plants cultivated under 70% of shading had higher contents of chlorophyll a, b, and total. During the initial phase with higher levels of radiation were fundamental for the development of T. subalbens seedlings.

To describe the epidemiologic profile and prevalence of cardiopathy in 163 Trypanosoma cruzi serum positive blood donor candidates, a descriptive study was carried out between August, 1996 and November, 1997 at the Londrina State University Chagas Disease Outpatient Clinic. The profile found was: young, average age 42.95 ± 8.62 years; male (65%); Caucasian (84%); low level of schooling; low family income; agricultural worker (26%); born in the state of Paraná (67%); from rural areas (85%); migrated to the city (85%); and the vector as the main mechanism of transmission. During the clinical characterization a chronic cardiac form was found in 38% of the patients and classified as cardiac suggestive form in 21% and little suggestive of Chagas disease in 17%. No significant difference was found among age group distribution, sex and the presence of cardiac symptoms in patients with or without cardiopathy. This study emphasizes the importance of expanding medical services to areas with a greater prevalence of infected individuals, in a hierarchical manner and aiming at decentralization.

ObjectivesMeat color is often seen by consumers as an indicator of freshness and wholesomeness. Nitrite-embedded (NE) packaging forms nitric oxide myoglobin, which imparts a bright red color similar to oxymyoglobin. However, limited research has determined the effects of NE packaging to improve the appearance of atypically dark cutting beef. Consumers’ perception of NE packaging ultimately determines its success in the market. Educating consumers through infographics can transfer knowledge more effectively than text alone, potentially being a useful method to introduce and simplify the complexity of NE packaging’s role in improving the surface color of beef steaks. The objectives of this study were to evaluate FreshCase® nitrite-embedded packaging’s effect on atypical dark-cutting beef steaks and to evaluate student consumer perception of nitrite-embedded packaging improving the surface color of beef before and after exposure to infographics containing equal content.Materials and MethodsAtypical dark-cutting (n = 13, pH 5.70 ± 0.09) and normal-pH (n = 13, pH = 5.57 ± 0.1) USDA Low Choice beef strip loins were selected 3 d postharvest. Atypical dark-cutting loins were cut into 2.54 cm thick steaks and randomly packaged in polyvinyl chloride film (PVC) or NE film. Normal-pH control loins were cut 2.54 cm and randomly packaged in PVC overwrap. Packages were placed in a coffin-style retail case under fluorescent lighting for 6 d. Instrumental color was observed every 24 h using a HunterLab MiniScan XE spectrophotometer. The color was determined as a* values and chroma. In the second objective, surveys using a ten-point Likert sliding scale (0 = not familiar at all, 10 = extremely familiar) were randomly allocated and emailed via Qualtrics to students enrolled in the Introduction to Animal Science course at Oklahoma State University. These surveys used a pre-questionnaire to evaluate students’ pre-perception of their knowledge of beef color and NE packaging. After the pre-perception questionnaire students were provided one of the following: a static infographic presented as a still image with annotated graphics, a 46 s video infographic with audio and animated graphics, or both infographic formats. A post-questionnaire followed exposure to students’ respective infographic to evaluate changes in the perception of knowledge.ResultsAtypical dark-cutting steaks treated in NE packaging had higher (P < 0.05, more red intensity) chroma and a* values compared to atypical dark-cutting steaks in PVC on d 4, 5, and 6. There was a significant difference (P < 0.05) in the students’ (n = 288) pre- and post-questionnaire self-assessment of their familiarity with NE packaging. Prior to randomly viewing infographics, students were less familiar (= 3.18) with NE packaging than after viewing infographics (= 6.46). However, there was no significant difference in perceptions (P = 0.22) between viewing the different infographic formats.ConclusionThe results suggest that NE packaging with consumer education can improve their perceptions and knowledge and enhance the appearance of atypical dark-cutting beef.

Abstract Purpose Hirschsprung's associated enterocolitis (HAEC) is a complication of Hirschsprung's Disease (HD) with considerable morbidity and mortality. The variability in presentation leads to a wide variety of the reported prevalence pre-and postoperatively. This systematic review aimed to clarify the prevalence of HAEC in short—(S-HD), long (L-HD), TCA and the type of operation used. Methods A systematic literature-based search for relevant cohorts was performed using Pubmed/Medline, Cochrane Library from its inception to May 2021. Studies reporting on pre-and postoperative enterocolitis, segment length, and surgical procedure (Soave, Swenson, Duhamel) were included. Pooled prevalence and subgroup analysis have been calculated for pre-and postoperative HAEC. Results 4738 articles were identified from the literature search, among which 57 studies, including 9744 preoperative and 8568 postoperative patients, were included. The groups were sorted by length of the aganglionic segment for further analysis. The pooled prevalence for preoperative HAEC was 18.3% for all types, 15.2% for S-HD and 26.1% for TCA. The pooled prevalence for postoperative HAEC was in total 18.2% for all segment lengths and used techniques. Subgroup analysis showed no significant difference in the occurrence of postoperative enterocolitis between the three techniques. Conclusion The prevalence of preoperative HAEC increases with segment length. However, pooled data suggest that the postoperative risk for developing HAEC, independently of the employed method and segment length, is comparable to the preoperative risk.
