Cucumber, a widely cultivated vegetable, is mostly grown under greenhouse conditions. In recent years, the overuse of inorganic fertilizers for higher yield attainment adversely has affected human health and the environment. Therefore, a greenhouse experiment was designed to evaluate the effects of different nutrient sources (poultry manure (PM) and mineral fertilizer (MF)) on productivity-enhancing parameters of cucumber via univariate and multivariate analyses. Amounts of PM and MF (NPK15:15:15) were added to coco-peat per cubic meter by weight/volume (w/v) ratios as follows: T1 (control), 60 kg PM; T2, 30 kg PM + 3 kg MF; T3, 30 kg PM + 5 kg MF, and T4, 30 kg PM + 7 kg MF. The univariate analysis performed on the collected data illustrated the significant enhancement in growth and productivity for the integrated use of PM and MF. Multivariate analyses (correlation, clustering, and Principal Component Analysis) validated the results of univariate analysis by differentiating treatments into two groups. The three treatments obtained a distinguished group from T1 (Control) and did not show significant differences among each other, with a maximum yield increase by T2 (74.6%). According to these results, T2 could improve cucumber productivity under greenhouse conditions. It can be taken as recommendations for better quality and yield enhancement in future improvement programs and cucumber-related farming communities.

Oman is endowed with enormous diversity of important food crops that have global significance for food security and has ancient history of cultivation of bread wheat (Triticum aestivum L.) with its divergent landraces, which are useful in crop improvement. 55 indigenous Omani accessions conserved at the USDA were evaluated in the winter season (November to April) of the years 2017-2018 and 2018-2019 on loamy soil under sprinklers in augmented design with 5 check varieties in 5 replications following crop husbandry practices as per national recommendations using 9 quantitative (descriptors) and 6 qualitative traits (anthocyanin pigmentation on plant parts). The data on traits were subjected not only for PC values and D values after varimax rotation through Kaiser normalization in Principal Component Analysis (PCA) but also for Agglomerative Hierarchical Clustering (AHC). The results indicated that indigenous bread wheat accessions were significantly different (p>0.05) for all the quantitative traits except number of tillers. The multivariate analyses led to formation of four diverse clusters from PCA analyses corresponding to four quadrants of bi-plot graphs and three clusters from AHC analysis corresponding to main clades of dendrogram. The parents were selected from common accessions of distinct clusters in all the multivariate analyses for hybridization for improving characters of growth for higher yield or productivity with pigmentation on one or two plant parts useful for DUS test of varieties. The indigenous bread wheat landraces / accessions were genetically diverse and have potential for use in national crop improvement programs for earliness and higher grain productivity with distinct identification markers.

Prediction Of Outcome

We investigated pregnancy outcome following transabdominal cerclage (TAC) in women with cervical insufficiency (CI) and explored parameters for predicting pregnancy outcomes following TAC. In this retrospective cohort study, we included 161 women with TAC. We considered demographic, obstetric, and gynecologic histories, pre- and postoperative cervical length (CL), and CL at 20–24 weeks as parameters for predicting outcomes following TAC. Univariate and multivariate analyses were used to identify risk factors for predicting delivery before 34 weeks after TAC. 182 pregnancies occurred after TAC, and 290 pregnancies prior to TAC were identified. The rate of delivery <34 weeks significantly decreased following TAC (5% versus 82%,P<0.001). Univariate analysis demonstrated that a short CL (<25 mm) at 20–24 weeks and adenomyosis were associated with delivery at <34 weeks’ gestation following TAC (P=0.015andP=0.005, resp.). However, multivariate analysis demonstrated that only a short CL (<25 mm) at 20–24 weeks was a significant predictor (P=0.005). TAC is an efficacious procedure that prolongs pregnancy in women with CI. A short CL at 20–24 weeks may predict the delivery at <34 weeks’ gestation following TAC.

The experimental studies were carried out on the fields of the Sumy NAU Training Research and Production Complex (TRPC) during 2016–2018.The soil of the experimental plot is typical deep-medium humus, large-dusty and medium-loam black soil on forest trees. The subject of the research was a white mustard variety of Oslava created at the Institute of Feed and Agriculture of the Podillya NAASU, entered in the Register of varieties suitable for cultivation in Ukraine in 2010. The aim of the research is to optimize the nutrition of the white mustard variety of Oslava through the complex application of mineral fertilizers and foliar fertilization under the conditions of the northeastern forest-steppe of Ukraine. The analysis of weather conditions, in particular the hydrothermal coefficient of Selyaninov (HTC), established that 2016 season was wet (HTC = 1.60), 2017 and 2018 were dry (HTC = 0.59 and 0.46). During the research, the cultivation technology was generally accepted in the experimental area, except for the elements studied. The results of the three-year study on the influence of foliar fertilizing under different mineral nutrition backgrounds on the yield of the white mustard variety Oslava are presented. It was found that the application of mineral fertilizers and complex fertilizers for the foliar feeding had a positive effect on the morphometric parameters of the white mustard, in particular, increased the plant height and the number of branches of the first order. The use of mineral fertilizers at the rate of N30P30K30 provided an increase in the yield by 0.34 t/ha, N60P60K60 – by 0.55 t/ha, N90P90K90 – by 0.61 t/ha on an average compared to the control. Therefore, for the maximum yield (2.14–2.21 t/ha) with a mass of 1000 seeds (5.39–5.54 g) of the white mustard under the conditions of the Northeastern Forest-Steppe of Ukraine, foliar fertilizing of Vuxal boron (3.0 l/ha) + Vuxal bioaminoplant 3.0 l/ha) and Spectrum B + Mo (2.0 l/ha) + Spectrum Ascorist (3.0 l/ha) should be applied on the background of N60-90P60-90K60-90, what provided an increase in the yield compared to the control of 0.58-0.65 t/ha.

The article presents an analysis of the determination of the effectiveness of mineral and organic fertilizers on the yield of winter wheat grain. The studies were carried out in 2017–2020 in the Rostov region on the southern chernozem. The object of research was the Doneko winter wheat variety. The predecessor is corn for grain. Ammonium nitrate, ANP fertilizer (16-16-16) and urea were used as mineral fertilizers, which were applied in the fertilization system of winter wheat and acted as a background option in the experimental scheme. ANP fertilizer (16-16-16) was introduced when sowing winter wheat, ammonium nitrate - scattered over thawed-frozen soil and carbamide in the heading phase by foliar method. Organomineral fertilizers were represented by the following types: Ruther, Leili 2000, Siamino Pro, Gumiful Pro, Soft Guard and Double Wine MKR (monocaliphosphate) produced by Biokepharm (Switzerland). The raw material for the production of organomineral fertilizers was the algae of the warm seas Laminaria. In the field experiment, the options for the joint application of foliar application and pre-sowing seed treatment with organomineral fertilizers were also studied. The control was the option without mineral fertilizers and the option with the background of the use of mineral fertilizers (farm fertilization system). It was found out that the use of organic fertilizers Ruter (0.5 or 0.25 l / t) and Leyli (0.25 l / t) for seed treatment before sowing, the use of Soft Guard (0.2 l / ha) and Gumiful Pro ( 0.2 l / ha) in the spring tillering phase and in the flag leaf phase against the background of sowing nitroammophoska at a dose of N32P32K32, random fertilizing on thawed-frozen soil with ammonium nitrate at a dose of N40 and the use of carbamide in the heading phase at a dose of N20 increased grain yield on average for 2018–2020 compared with the control (fertilization system of the farm) by 0.73 t / ha, or 23.0%. The maximum yield increase from the root-forming agent Ruther, used for pre-sowing seed treatment, reached 0.36 t / g, or 11.3%.

AbstractPurposeWe aimed to develop a non-invasive neural test of language comprehension to use with non-speaking children for whom standard behavioural testing is unreliable (e.g., minimally-verbal autism). Our aims were three-fold. First, we sought to establish the sensitivity of two auditory paradigms to elicit neural responses in individual neurotypical children. Second, we aimed to validate the use of a portable and accessible electroencephalography (EEG) system, by comparing its recordings to those of a research-grade system. Third, in light of substantial inter-individual variability in individuals’ neural responses, we assessed whether multivariate decoding methods could improve sensitivity.MethodsWe tested the sensitivity of two child-friendly covert N400 paradigms. Thirty-one typically developing children listened to identical spoken words that were either strongly predicted by the preceding context or violated lexical-semantic expectations. Context was given by a cue word (Experiment 1) or sentence frame (Experiment 2) and participants either made an overall judgement on word relatedness or counted lexical-semantic violations. We measured EEG concurrently from a research-grade system, Neuroscan’s SynAmps2, and an adapted gaming system, Emotiv’s EPOC+.ResultsWe found substantial inter-individual variability in the timing and topology of N400-like effects. For both paradigms and EEG systems, traditional N400 effects at the expected sensors and time points were statistically significant in around 50% of individuals. Using multivariate analyses, detection rate increased to 88% of individuals for the research-grade system in the sentences paradigm, illustrating the robustness of this method in the face of inter-individual variations in topography.ConclusionsThere was large inter-individual variability in neural responses, suggesting inter-individual variation in either the cognitive response to lexical-semantic violations, and/or the neural substrate of that response. Around half of our neurotypical participants showed the expected N400 effect at the expected location and time point. A low-cost, accessible EEG system provided comparable data for univariate analysis but was not well suited to multivariate decoding. However, multivariate analyses with a research-grade EEG system increased our detection rate to 88% of individuals. This approach provides a strong foundation to establish a neural index of language comprehension in children with limited communication.

SUMMARYPoultry manure and mineral fertilizers at two rates of application (medium and high) and in different combinations, together with a non-fertilized control, were tested at the Experimental Station of the Agricultural University of Padova, Italy (45° 21′ N, 11° 58′ E) in 1985–89.Compared to the control, all the fertilization treatments increased the incidence of larger-sized bulbs of onion and tubers of potato, improved the fruit colour of processing tomato and the raw protein content of spinach, but reduced the acidity and acids: soluble solids ratio of tomato and the dry matter content of spinach leaves.In addition, the application of 140 kg/ha of N, 140 kg/ha of P2O5 and 100 kg/ha of K2O as mineral fertilizer or as poultry manure gave the best scores of processing suitability of potato, both for sticks and chips. All the fertilization formulae, except for 140 kg/ha of N, 140 kg/ha of P2O5 and 100 kg/ha of K2O as poultry manure alone, showed significant decreases in the extractable sucrose ratio in sugarbeet, compared with the control. In processing tomato, the best scores of suitability for paste transformation were obtained with mixed fertilization (1/3 poultry manure and 2/3 mineral fertilizers) applying 210 kg/ha of N, 210 kg/ha of P2O5 and 150 kg/ha of K2O and the plots receiving only mineral fertilizers produced fruits with less favourable values of pH and electrical conductivity compared to the poultry manured ones.

Abstract Background: PTLD is a rare, often fatal, complication of SOT. Several studies have identified clinical prognostic factors in PTLD. However, no published studies to our knowledge have yet correlated outcome with the number (#) or type of tumor infiltrating T-cells, which in other types of lymphoma may have prognostic value. We hypothesized that tumor infiltrating T-cells, including TIA1-CTCs and Tregs, would predict survival in SOT PTLD. Methods: We searched the Cleveland Clinic pathology archives for SOT patients (pts), who were diagnosed with PTLD between 1987 and 2007; reviewed the medical records and extracted clinical information and outcomes; performed immunohistochemical (IHC) studies for CD3, TIA-1, and FOXP3; and analyzed the data by Cox proportional univariate and multivariate analyses. Results: We identified 62 SOT pts (heart, 22; lung, 17; kidney 15; liver, 7; pancreas, 1), who were diagnosed with PTLD at median age of 51 years (range 7–73). The median time from SOT to PTLD was 1.8 years (range 0.2–20.9). 1st therapeutic intervention (1st TI) (usually >1) included “complete” resection (4), decreased immunosuppression (51), acyclovir or gancyclovir (32), rituximab (R) (18), “CHOP” chemotherapy (11), radiation therapy (7), and interferon (4). Response to 1st TI was CR (34) or PR (10). The median follow-up among surviving pts is 3.6 years (range 0.1–11.7). 35 (including 4 CHOP and 9 R) pts have died; only 2 CHOP but all 9 R pts died from PTLD. IHC studies in 42 evaluable cases showed the following median # (and range) of cells /10 hpf: CD3 525 (8–2451), TIA1-CTCs 304 (6–1238) and FOXP3 13 (1–338). On univariate analysis, younger age, prior rejection episodes <2, PS <2, LDH normal, extranodal sites (ENS) <2, IPI <4, 1st TI >1, 1st TI with CHOP, # of CD3 cells >550/10 hpf, and # of TIA1-CTCs >300/10 hpf were associated with an improved overall survival (OS), PTLD-specific survival (PSS), and/or progression-free survival (PFS). On multivariate analyses, only PS <2, ENS <2, and 1st TI with CHOP remained independent predictors of outcome. Among the subset of 47 pts with monomorphic B-cell (MMBC) PTLD, these same clinical factors were also independently statistically significant. Conclusions: High #s of infiltrating T cells and TIA1-CTCs are associated with a favorable outcome and may reflect a relatively intact local anti-tumor response. Tregs, which may potentially antagonize such a response, are uniformly low and do not correlate with outcome in PTLD. In this analysis, a significant minority of SOT pts treated initially with single agent R still died from PTLD while pts treated initially with CHOP (with or without R) appeared to have a better outcome, arguing for its early use - at least in a subset of pts. Future studies should attempt to identify biological factors that predict which MMBC PTLD pts might benefit from the addition of CHOP to standard R as part of 1st TI.

The effectiveness of herbicides in spring barley crops on different nutrition backgrounds was studied in field experiments on dark gray forest soil of medium loamy particle size distribution in the conditions of Volga-Vyatka region. It is revealed that on both backgrounds of fertilizer application the barley formed a maximum yield, when applying the herbicide Bomba. When using this herbicide in making mineral fertilizers N54P54K54 the productivity was 2.71 tons per hectare and a dose N70P70K70 – it was 2.83 tons per hectare. On average for three years, the maximum (11.35%) protein content was appeared in the preparation by Sekator turbo herbicide on the background of fertilizer application of N70P70K70.

637 Background: While estrogen receptor (ER) negativity has been consistently associated to higher pCR rates after NACT in BC, few data regarding the association of PR with pCR has been reported. PR positivity has been related to taxol resistance in in vitro chemosensitivity assays. Our aim was to investigate the putative role of PR in the prediction of pCR in a cohort of BC pts receiving NACT. Methods: Medical reports of all pts receiving NACT and breast surgery between 2004 and 2006 in our institution were reviewed. Baseline clinical and histological features, along with type of preoperative therapy were examined as variables for association with pCR (no invasive tumor in breast and axilla) using univariate and multivariate analyses. Results: 128 pts were included. 73.4% received anthracycline and taxanes (A&Tx) based CT and 9.4% also received trastuzumab (T). PR+ (≥ 10%) was significantly associated with low histological grade (HG), low Ki67 (<10%), HER-2- (Herceptest 0,1,or 2 with FISH-) and ER+ (≥10%). Overall pCR rate was 18.8%. No PR+ patient achieved pCR. In univariate analysis, high HG, ER-, PR-, HER-2-, high Ki67, T therapy, and number of CT cycles were significantly associated with pCR. In multivariate analysis only HER-2 and PR status were statistically significant. Similarly, PR and HER-2 status were independently related to pCR in the subgroup of pts receiving A&Tx (N = 94, 20.2%pCR). In the HER-2- subgroup (n = 89, 9%pCR) only ER independently predicted pCR, while in the HER-2+ subgroup (n = 33, 42.4%pCR, 57.1%pCR with T), both PR- and T therapy were the only predictive factors for pCR in the univariate and multivariate analyses. When the 24 HER-2+ pts treated with A&Tx (23 taxol/1 taxotere) ± T were separately analyzed, only PR retained statistical significance in the multivariate model. Conclusions: In our cohort of BC pts treated with NACT, PR status independently predicts pCR in the whole population as well as in the A&Tx-treated and in the HER-2+ subgroups. In the HER-2+ pts receiving A&Tx ± T PR negativity was the only factor associated with pCR. PR status merits further investigation as a predictive factor for pCR to NACT, in particular in HER-2+ population. No significant financial relationships to disclose.
