Flavoring seasonings are food additives added with the aim of increasing flavor(palatability) and covering up deficiencies in food in terms of taste. The natural glutamatecontent of mushrooms has the potential to be used as a flavoring ingredient, one of which isoyster mushrooms. The quality of natural flavoring of oyster mushrooms is determined by theformula of the ingredients and the way they are produced. The drying process can affect thewater content and color of seasoning.  This study aims to determine the water content and natural flavoring of oystermushrooms based on initial treatment. This study was an experimental study using aCompletely Randomized Design with 6 treatment trials (non-blanching, blanching, sodiumbisulfite immersion, citric acid immersion, blanching + sodium bisulfite immersion, andblanching + citric acid immersion), and 3 test replications. The moisture content test wasperformed by the AOAC oven method and color analysis was measured using Konica MinoltaCR-10 Color Reader. Observational data were analyzed using univariate analysis.  The results showed that the initial treatment had a tendency to increase water content.Moisture content for all samples based on pretreatment meets the quality criteria for dryproducts that is 10%. The results of the color analysis showed an increase in the value of eachtreatment but did not show any real difference in color. The treatment using sodium bisulfiteimmersion and blanching showed an increase in brightness intensity and a good chroma valuecategory compared to the control value. Based on Hue value in each treatment has the samecolor scheme, namely yellow – red. OKeywords: Oyster mushroom, Water Content, Color, Pre treatment, blanching

ABSTRACT Ornamental plants are all plants grown for their beauty and are commonly used in gardening and landscaping. The colorful fruits and varied foliage colors that typify ornamental peppers provide a vibrant garden display that rivals other ornamental plants. This study aimed to evaluate the potential ornamental use of eight pepper accessions, Capsicum annuum, from the Capsicum Germplasm Bank of the Universidade Federal do Piauí, using qualitative and quantitative descriptors. The experiment was carried out in a greenhouse at the Department of Plant Science, Centre of Agricultural Sciences of Universidade Federal do Piauí, where the accessions were evaluated through a completely randomized design, with eight replicates, one plant per plot, and characterized based on 35 descriptors, 23 of which were qualitative and 12 quantitative. Data on quantitative descriptors were submitted to univariate analysis of variance, followed by Scott-Knott clustering test at 5% probability. Data on qualitative multicategorical descriptors were considered based on observations of statistical mode. The eight accessions evaluated have ornamental potential and are within the standards established by the Instituto Brasileiro de Floricultura. The accessions BAGC 98, 100, 203, 207, 224, and 236 accessions are suitable for cultivation in pots, while BAGC 220 is suitable for garden cultivation. BAGC 199 is the most promising accession because it supports all quality criteria required for size, foliage, flowers, and fruit proposed by the Veiling Holambra Cooperative.

Luas perkebunan kelapa sawit di Indonesia pada tahun 2014 mencapai 10 juta Ha. Pertumbuhan yang pesat diikuti dengan produksi crude palm oil (CPO) dan palm karnel oil (PKO) yang juga meningkat, sekaligus produk sampingan berupa limbah. Salah satu limbah pabrik kelapa sawit yang jumlahnya besar adalah tandan kosong kelapa sawit (TKKS). Tandan kosong kelapa sawit merupakan limbah organik yang berpotensi dimanfaatkan dibidang pertanian. Akan tetapi, TKKS memiliki nilai C/N yang cukup tinggi, akibatnya sukar dan lama untuk terdekomposisi. Salah satu cara pemanfaatan TKKS adalah dengan dilakukan pengomposan dengan pengkayaan urea. Diharapkan dengan perlakuan tersebut TKKS akan cepat terdekomposisi dan dapat segera dimanfaatkan oleh tanaman. Penelitian ini bertujuan untuk (1) mengetahui pengaruh pemberian urea terhadap pengomposan TKKS dan (2) mengetahui pengaruh peningkatan dosis urea terhadap kualitas kompos TKKS. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) faktor tunggal dengan 5 perlakuan, yaitu U1 (urea 0 g setara dengan nilai C/N=), U2 (urea 30,9 g setara dengan nilai C/N=), U3 (urea 79,3 g setara dengan nilai C/N=), U4 (urea 176,1 g setara dengan nilai C/N=) dan U5 (urea 466,3 g setara dengan C/N = ) dan 9 ulangan, sehingga diperoleh 45 satuan percobaan. Hasil penelitian menunjukan bahwa pemberian urea berpengaruh sangat nyata terhadap susut bobot, kadar air, nilai pH kompos, C-organik, N-total, P-tersedia, dan nilai C/N, selain itu pemberian urea mengakibatkan terjadi perubahan tekstur dan warna pada kompos TKKS. Pemberian dosis urea 466,3 g mampu meningkatkan kandungan N-total, serta menurunkan nilai C/N dan nilai pH kompos. Pemberian dosis urea 79,3 g atau setara dengan C/N = mampu meningkatkan kandungan P-tersedia dan kadar air, menurunkan susut bobot dan kandungan C-organik, serta menunjukan perubahan tekstur dan warna yang lebih baik.

Calla lily is an appreciated specie used for flower arrangements. In spite of its commercial importance, there is little information on calla lily postharvest conservation. Thus, this study aimed to determine the best sucrose concentration for pulsing and cold storage conditions to extend calla lily postharvest durability. Flower stalks were submitted to a pulsing pre-treatment using 2, 4, 8, 12 and 16% sucrose in the solution, for one hour, plus a treatment with direct storage in cold chamber (4ºC), without a prior-treatment. Dry storage or storage in solution with the commercial product Flower® was also tested. A completely randomized design was used with four replicates and three inflorescences per plot. Spathe length and width were daily measured from which the opening and wilting processes were analyzed. It was observed that pulsing with sucrose was efficient in extending calla lily inflorescences opening process and durability. Dry storage for short periods (less than six days) can also be used, but a prior-treatment with 12% sucrose pulsing for one hour or with a water supply for the same period was required. For storage in solution, a pulsing with 5% or 7.5% sucrose was recommended.

Background: Extranodal natural killer/T cell lymphoma (ENKL) is an aggressive Epstein-Barr virus (EBV) associated lymphoma with a strong geographical predilection for Asia and South America. While treatment outcomes of advanced stage (AS) disease (i.e., stage III and IV) are uniformly poor, early stage (ES) disease treated with concomitant or sequential chemotherapy (ChT) and radiotherapy (RT) can yield good long-term outcomes. Currently there is no standard therapy for ES ENKL. We describe our experience treating patients with ES ENKL in 3 tertiary cancer centres in Singapore. Method: We performed a retrospective analysis using data from Singapore Lymphoma Study Group database which captures patients from 3 largest tertiary cancer centres in Singapore: National Cancer Centre Singapore (NCCS), Singapore General Hospital (SGH) and National University Cancer Institute, Singapore (NCIS). We included patients with stage I or II ENKL that were treated with ChT and RT from 1996 to March 2019. Patients who did not receive treatment or received radiotherapy alone were excluded. We recorded data on patient demographics, chemotherapy regimen, radiotherapy dosage, sequencing of treatment, response and survival outcomes. End of treatment overall response rates (ORR) included those who achieved complete response (CR) and a partial response (PR). Progression free survival (PFS) was defined as date of diagnosis to date of progression, relapse or death. Overall survival (OS) was defined as date of diagnosis to date of death from all causes. Survival distributions were estimated by the Kaplan-Meier method. Assuming cox proportional hazards models, univariate analysis for OS was performed and Wald tests were used to evaluate the statistical significance. All the statistical analysis was performed using R. Results: There were 56 patients who fulfilled the inclusion criteria. Forty (71%) were male, 47 (84%) were Chinese and the median age of this cohort was 50 (range 18-80). Thirty-one (55%) patients had stage I disease and all had nasal involvement. All patients had ECOG performance status of 0 or 1 and most had low or low-intermediate international prognostic index (IPI) score. Ten patients (18%) had B-symptoms and LDH was elevated in 22 (39%). Pre-treatment positron emission tomography-computed tomography (PET/CT) was performed in 36 (64%) patients. Pre-treatment EBV titres were tested in only 23 patients and they were detected in 17 (74%) of patients. Twenty-five patients (45%) had sandwich (ChT, RT then ChT), 25 (45%) had ChT followed by RT, while 6 had RT followed by ChT. None had concurrent ChT/RT. The most commonly used ChT regimen was ICE (ifosfamide, carboplatin, etoposide) in 19 patients and SMILE (steroids, methotrexate, ifosfamide, L-asparaginase, etoposide) was used in 9 patients. Most patients (75%) did not receive L-asparaginase containing regimens. The median RT dose was 50Gy. The ORR for this cohort was 87.5% and 7 patients (12.5%) progressed at the end of treatment. Our median duration of follow up is 3.5 years (range: 0.25 - 21.6 years). The 5-year OS for stage I and II disease were 78.5% (95% CI, 64.2%-96.0%) and 65.6% (95% CI 47.5% to 90.5%) respectively. The 5-year PFS for stage I and II disease was 78.5% (95% CI 64.2%-96.0%) and 58.8% (95% CI 40.9% to 84.5%) respectively. On univariate analysis, only the sequence of therapy i.e., the sandwich ChT-RT-ChT approach when compared to sequential treatment with ChT followed by RT, was associated with better OS with a hazard ratio (HR) of 0.18 (95% CI 0.04 to 0.84 , p = 0.03). When L-asparaginase containing regimens were compared against those without, no statistical significant difference was observed in OS in ES ENKL, with HR of 3.38 (95%CI 0.44-26.15, p=0.243) Conclusion: Survival outcomes for ES ENKL especially that of stage I ENKL, are good with chemoradiotherapy. This contrasts against the treatment outcomes of AS ENKL. It is likely that many patients in this study were under-staged since PET scans were only performed in 64% of patients. Within the limits of this retrospective analysis and the small numbers, the ICE chemotherapy regimen appears to be an effective treatment when "sandwich"-sequenced with radiotherapy.

BackgroundDespite the clinical effectiveness of Immune Checkpoint Inhibitors (ICI) in lung cancer, only around 20% remain disease free at 5 years. Predictive biomarkers for ICIs are neither sensitive nor specific. Here, we used the GeoMx Digital Spatial Profiler (DSP) (NanoString, Inc.) to analyze high-plex protein in a quantitative and spatially resolved manner from single formalin-fixed paraffin embedded tissue sections toward the goal of identification of new biomarkers with better predictive value.MethodsPre-treatment samples from 56 patients with NSCLC treated with ICI were collected, represented in Yale tissue microarray 471 (YTMA471), and analyzed. A panel of 71 photocleavable oligonucleotide-labeled primary antibodies (NanoString Human IO panel) was used for protein detection. Protein expression was measured in 4 molecularly defined tissue compartments, defined by fluorescence co-localization (tumor [panCK+], leukocytes [CD45+/CD68-], macrophages [CD68+] and an aggregate stromal immune cell compartment, defined as the sum of leukocyte and macrophage expression [panCK-/CD45+/CD68+]) generating 284 variables representing potential predictive biomarkers. Promising candidates were orthogonally validated with Quantitative Immunofluorescence (QIF). Pre-treatment samples from 40 patients with NSCLC (YTMA404) that received ICI, and 174 non-ICI treated operable NSCLC patients (YTMA423) were analyzed to provide independent cohort validation. All statistical testing was performed using a two-sided significance level of α=0.05 and multiple testing correction (Benjamini-Hochberg method, FDR < 0.1).ResultsInitial biomarker discovery on 284 protein variables were generated by univariate analysis using continuous log-scaled data. High PD-L1 expression in tumor cells predicted longer survival (PFS; HR 0.67, p=0.017) and validated the training cohort. We found 4 markers associated with PFS, and 3 with OS in the stromal compartment. Of these, expression of CD66b in stromal immune cells predicted significantly shorter OS (HR 1.31, p=0.016) and shorter PFS (HR 1.24, p = 0.04). Tertile analysis using QIF on all three tissue cohorts for CD66b expression, assessed by QIF, showed that CD66b was indicative but not prognostic for survival [discovery cohort, YTMA471 (OS; HR 3.02, p=0.013, PFS; HR 2.38, p=0.023), validation cohort; YTMA404 (OS; HR 2.97, p=0.018, PFS; HR 1.85, p=0.1), non-ICI treated cohort YTMA423 (OS; HR 1.02, p>0.9, PFS; HR 0.72, p=0.4)].ConclusionsUsing the DSP technique, we have discovered that CD66b expressed in the stromal immune [panCK-/CD45+/CD68+] molecular compartment is associated with resistance to ICI therapy in NSCLC. This observation was validated by an orthogonal approach in an independent ICI treated NSCLC cohort. Since CD66b identifies neutrophils, further studies are warranted to characterize the role of neutrophils in ICI resistance.AcknowledgementsDr Moutafi is supported by a scholarship from the Hellenic Society of Medical Oncologists (HESMO)Ethics ApprovalAll tissue samples were collected and used under the approval from the Yale Human Investigation Committee protocol #9505008219 with an assurance filed with and approved by the U.S. Department of Health and Human Services
