Abstract
The issues of development and implementation of resource-saving technologies in broiler poultry farming have a complex purposefulness and their solution must be scientifically substantiated and cost-effective. The productive qualities of meat chickens and broiler chickens of the productive crosses are significantly influenced by many factors that make up the conditions of keeping and feeding. The use of Apex and Emicidin preparations both separately and in combination with each other when rearing chickens of the broiler parent flock of the Ross 308 cross had a positive effect on their productivity and the quality of hatching eggs obtained at the end of the productive period, at the age of 52 weeks. Egg production per initial hen exceeded that in the control group by 2.6% in experimental group 1 (Emicidin), by 3.2% in experimental group 2 (Apex 3010), and by 5.8% in experimental group 3 (combined use of Emicidin and Apex 3010). The determined zootechnical indicators showed high efficiency of the use of the GerbaStor preparation for the floor rearing of broiler chickens of the Ross-308 cross in conditions of increased stocking density in winter. The difference in the productivity index was 18 units, and in meat yield from 1 m² of floor, it was 1.37 kg (3.8%) in favor of the broilers of the experimental group 2, who received GerbaStor. The profitability of the production and sale of meat of broilers grown under an increased stocking density using the GerbaStor preparation was 3.95% higher than that of broilers in the control group.

Published: December 2021

Abstract
Homogenate is a source of a huge amount of biologically active substances. However, it is produced in a small number of apiaries, since the cultivation of drone brood negatively affects honey productivity. This paper aimed to study the influence of rearing drone larvae on the power and honey productivity of bee colonies since these issues are not widely addressed in scientific literature. Three groups (control, experimental 1, and experimental 2) of 10 bee colonies were formed by the method of pairs-analogs. One brood frame was placed in the bee colonies of the first experimental group, and two frames were placed in the colonies of the second experimental group. The brood frames were placed on June 12, the clipping was done on June 30, and the honey was collected on July 12. The power of colonies was taken into account after wintering (in March) and at the end of the pre-wintering season (in November). As a result of the research, it was revealed that the homogenate of drone brood can be obtained in apiaries of the Primorsky Krai. It was proved that when adding one brood frame to obtain a homogenate, the main production of the apiary - honey, does not decrease, and a negative effect on honey productivity was observed when adding the second brood frame.

Published: December 2021

Abstract
Today, the urgent task is to preserve the gene pool of local and regional breeds with their special and useful traits. These features allow them to represent an additional reservoir of genetic diversity. Analysis of the genetic diversity of three pig populations (Kemerovo pig breed, Kemerovo × Landrace crossbreds and Kemerovo × Landrace × Pietrain crossbreds) by microsatellites showed that significant allelic diversity is observed for some loci, while for others it is low. The highest number of alleles was in the purebred pigs in comparison with crossbreds. The greatest range of alleles per locus was noted in the three-breed cross pigs. The most polymorphic locus in all populations was SO005, and the least polymorphic was SW72. It was noted that for most loci the observed heterozygosity corresponds to the expected one, while for others a shortage of heterozygotes is detected.

Published: December 2021

Abstract
The selection of the Black Sea aquatic area as a hydrobiont biologically active compound source allows resolving several environmental problems including development of an integrated hydrobiological resource management system for the Black Sea as a new sector of modern pharmacology. Aquatic organisms produce unique secondary metabolites. This paper presents the results of studies on the development of the biologically active substance extraction technology from non-commercial aquatic organisms as well as a preliminary assessment of the biochemical activity of the substrates obtained. Biologically active substances were extracted using the of two-phase extraction method in conjunction with ultrasound. For the substrates, the antioxidant activity was determined utilising the method that allow conducting screening of pharmaceutical raw materials and biologically active substances with high antioxidant activity. The protective activity evaluation was carried out during the study of the enzymatic alcoholic fermentation kinetics within a self-contained system. The evaluation of lymphocytes proliferative activities influenced by the obtained substrates was carried out using the cultivation method. The acquired data allows recommending the two-phase extraction method combined with ultrasonic voiceover as the effective one when processing analogical marine raw materials. The isolated substrates are characterised by a pronounced biochemical activity in relation to the living systems cells, which suggests a significant synergistic effect with derivatives of the microalgae Chlorella Vulgaris.

Abstract
The article presents results of research of monocultures and association of lactic-oxide bacteria, purple nonsulfur bacteria and yeast on indicators of stimulation of growth processes, nitrogen fixation and phosphate mobilization for 2 crops: one-year and longterm. The research was carried out in both laboratory and production conditions. It is shown that milk-oxide and purple nonsulfur bacteria stimulate growth processes of wheat variety Nador in aquatic culture by 20-30%, and their consortium with yeast - by 30%. In comparison with control, an increase of 3.4 t/ha in the yield of Golden Delishes apples was detected with 2fold treatment based on a consortium of lactic oxide, purple nonsulfur bacteria and sucromycetes. It was determined that all the strains of the above-mentioned groups of microorganisms studied mobilized hard-to-soluble compounds of phosphorus, and only purple nonsulfur bacteria were capable of nitrogen fixation.

Published: December 2021

Abstract
The work is devoted to improving clonal micropropagation methods of the genus Rubus representatives. When cultivating R. arcticus L. cultivars, the optimal concentration of 6-benzylaminopurine (6-BAP) was 0.3 mg L−1. Significant effect of FeEDTA concentration in the nutrient medium on multiplication of R. idaeus L. cultivars was established. The interaction of auxin type and plant genotype was revealed during rooting of blackberry cultivars and raspberry-blackberry hybrids. The nutrient medium supplemented with 0.5 mg L-1 indoleacetic acid contributed to the highest percentage of rhizogenesis in R. arcticus representatives (82%). The optimal growth regulator for conservation of raspberry explants was 6-BAP at a concentration of 0.3 mg L-1. One of the most representative in vitro collections of Rubus cultivars has been created.

Abstract
The potato cyst nematodes (PCN) Globodera rostochiensis and Globodera pallida are the most common pests feeding on potato roots. These pests have an aggressive distribution dynamic and bring a lot of damage to yield. The study presents results of comprehensively test new potato genotypes for resistance to the golden potato nematode (Globodera rostochiensis), for its further use in breeding and the creation of economically valuable resistant varieties. Almost half of the samples showed laboratory resistance to golden potato nematode, the rest were susceptible. 26 samples have shown the presence of two molecular markers (N146, N19), indicating the presence of H1 gene. Almost all samples showed a correspondence between laboratory resistance and the presence of H1 gene markers.

Published: December 2021

Abstract
Soil cover of the northern most regions of Eurasia are considered as underestimated in terms of their possible role in expansions of current agriculture to the cryolithozone. In this context, abandoned agricultural soils of Yamal region were investigated in terms of morphology, chemistry and taxonomy microbiome compositions and compared in these terms with mature tundra and taiga soils of pristine environments. The level of soil fertility was low in all cases – former agricultural soils and pristine ones. The level of microorganism’s biodiversity was higher in soils of agricultural lands. This fact indicates that the agricultural soil treatment in polar terrestrial ecosystem results in increasing of soil microbial biodiversity due to diversification of ecological niches. Also the is an essential lack of nitrogen sources in all permafrost affected soils studied.
Comparative study of photosynthetic pigments in the leaves of forage plants of the cryolithozone of Yakutia
Authors: Nokhsorov V V , Petrov K A 
Published: December 2021

Abstract
Thin-layer chromatography and spectrophotometry were used to determine the content of photosynthetic pigments (chlorophylls a and b, carotenoids) in green leaves of forage plants. It was found that the content of carotenoids was high for forage grasses with a high content of green pigments. It was revealed that β-carotene plays the most important role since it is a precursor of vitamin A and lutein, which has a high antioxidant (protective) property. According to modern concepts, lutein and β-carotene actively function in various organs of herbivores. They play a special role in the functioning of the mammalian visual apparatus, protecting this organ from the light factor. In addition, lutein is one of the physiologically active substances that make up cow’s milk.

Published: December 2021

Abstract
Kale is one of the top economically valuable crops in the world because of its high antioxidant content. Research shows that the antioxidant profile of Brassica crops varies with growth stages due to soil fertility, temperature, light and other agronomic factors. This study aimed to analyze the effect of potassium humate on phenolic compound content, the greatest contributor to the antioxidant properties of the highest-ranking superfood kale (Brassica oleracea var. sabellica). Our results showed that potassium humate at different growth stages elicited phenolic compounds in the studied samples. Leaves of 22 weeks old plants accumulated phenolic compounds about two times higher than those of 7 weeks old plants. Vitamin C content was increased by potassium humate treatment at 7 weeks. At 22 weeks levels in controls and treated kale leaves did not significantly differ.
RNA-Seq of potato plants reveals a complex of new latent bacterial plant pathogens

Abstract
The throughput and single-base resolution of RNA-Sequencing (RNA-Seq) have contributed to a dramatic change in diagnostics of viruses and other plant pathogens. A transcriptome represents all RNA molecules, including the coding mRNAs as well as the noncoding rRNA, tRNA, etc. A distinct advantage of RNA-Seq is that cDNA fragments are directly sequenced and the reads can be compared to available reference genome sequences. This approach allows the simultaneous and hypothesis-free identification of all pathogens in the plant. We conducted surveys for potato (Solanum tuberosum L.) -associated phytopathogenic bacteria in 56 original and GenBank RNA-seq data sets for potato breeding material. Bacteria of genera Pseudomonas, Burkholderia, Ralstonia, Xanthomonas, Agrobacterium, and species of family Enterobacteriaceae were most frequently detected in RNA sets from the studied plants. RNA-seq reads identified as Xanthomonas spp. were within X. vesicatoria, and some other species. Xanthomonas spp. covered up to 9,1% of all reads and included the major clades of these bacteria known as pathogens of solanaceous crops, but potato. Bacteria of genus Xanthomonas infect different plant species under artificial inoculation, suggesting that they are shared among wild plants and crops. Our studies indicated that a larger number of solanaceous plants can be occupied by specific Xanthomonas pathovars as endophytes or latent pathogens. Revealing bacteria distribution in the plant breeding material using RNA-seq data improves our knowledge on the ecology of plant pathogens.
A Dyadic Investigation of Depressed Affect and Interspousal Behavior in Couples With Chronic Back Pain
Authors: Post Kristina M , Smith David A , Burns John W , Porter Laura S , Keefe Francis J 
Published: December 2021

Abstract

Background
Depression and marital discord are characteristic not only of individuals with chronic low back pain (ICPs) but also of their spouses.

Purpose
We examined actor–partner interdependence models to evaluate associations among depressed affect and criticism and support of partners at the same time point (concurrent effects) and 3 hr later (lagged effects). Fully dyadic models were used to account for both within-person and cross-spouse associations among depressed affect, criticism, and support for ICPs and spouses. We also examined the direction of the relationships (depressed affect predicting behavior and behavior predicting depressed affect) all while controlling for pain intensity, pain behavior, and the prior dependent variable.

Methods
ICPs (n = 105) and their spouses completed electronic diary measures of depressed affect and behavior (criticism and support) five times a day for 2 weeks. Hierarchical linear modeling with person-mean centering was used for data analysis.

Results
Within the same 3 hr epoch, more depressed affect was related to higher criticism and generally less support. Lagged analyses suggested bidirectional relationships between spouse’s own depressed affect and spouse’s own criticism of ICPs. Spouse depressed affect was also associated with decreased support received from ICPs. Pain behavior and pain intensity were also related to depressed affect, criticism, and support especially concurrently.

Conclusions
Theories and interventions need to address not only ICP depressed affect but also spouse depressed affect, as spouse depressed affect may be a stress generating precursor to criticism and support.

Published: December 2021

Abstract

Objectives
An increasing number of incidental testicular tumors are diagnosed in patients during infertility workup. The aim of this study was to evaluate the accuracy of frozen section examination (FSE) for the management of these tumors.

Methods
We retrospectively studied a series of 46 testicular tumors diagnosed during exploration for infertility from 2000 to 2019 and submitted for FSE.

Results
A diagnosis of malignancy was made in 23 cases on both gross examination (yellow-white or cream-colored nodules for seminomas) and FSE, then confirmed on final diagnosis in 22 of the cases. One seminoma reported on FSE was revised as being a Leydig cell tumor. The 23 other lesions were diagnosed as benign on FSE, including 11 Leydig cell tumors (yellow-brown nodules), 2 Leydig cell hyperplasias, and 10 whitish fibrous lesions. All Leydig cell lesions were confirmed except 1, which was reclassified as a Sertoli cell tumor. Of the 10 cases of fibrous lesions, 6 were associated with malignancy.

Conclusions
The high incidence of Leydig cell tumors and the accuracy of FSE for these lesions demonstrate the interest in FSE. In contrast, FSE is not reliable for fibrous lesions, and surgeons should be aware that a fibrosis result often corresponds with regressed tumors.

Published: December 2021

AbstractPurposeThis study assessed whether personality testing of postgraduate year 1 (PGY1) pharmacy residency applicants was feasible and predicted important selection outcomes, including interview offers.MethodsApplicants to the PGY1 pharmacy residency program at a large academic medical center were invited to complete a 50-item online personality test based on the 5-factor model (ie, the “Big Five”). Scores were sealed until after matching, at which point they were compared to screening, interview, and ranking and match outcomes. Endpoints of interest included the feasibility of the test (eg, time required for completion, completion rate) and whether personality predicted the odds of an interview offer.ResultsThe personality test was taken by 137 PGY1 applicants (69.5%) and required a median of 6.8 minutes to complete. Openness to experience was associated with decreased odds of an interview offer (adjusted odds ratio [OR], 0.86; 95% confidence interval [CI], 0.75-0.98), whereas conscientiousness and extraversion were associated with increased odds of an interview offer (conscientiousness: adjusted OR, 1.26; 95% CI, 1.02-1.55; extraversion: OR, 1.16; 95% CI, 1.03-1.31). When combined with traditional screening criteria (eg, awards, leadership positions), openness to experience and extraversion remained predictors of an interview offer (in the directions specified above), whereas conscientiousness did not. In an exploratory analysis of interviewees, agreeableness was a negative predictor of interview score. Personality did not predict screening scores or final ranking.ConclusionPersonality testing, based on the traits desired at individual residency programs, could be a valuable addition to the methods used for selecting PGY1 pharmacy residents.
P010 FEASIBILITY OF MIDLINE RECONSTRUCTION WITHOUT MYOFASCIAL RELEASE (COMPONENT SEPARATION) AFTER PREOPERATIVE INFILTRATION OF LATERAL ABDOMINAL WALL MUSCULATURE WITH BOTULINUM TOXIN

Published: December 2021

Abstract

Aim
Aim of the analysis was to evaluate whether preoperative botulinum toxin infiltration may facilitate anatomical midline reconstruction without the need for – otherwise pre-operative assumed – surgical component separation.

Material and Methods
Total of 58 patients with complex abdominal wall hernias were included in our single-center retrospective analysis between 03/2015 and 12/2020. Size of the defect, HSV/ACV-ratio, rectus-to-defect-width-ratio (“Carbonell-Index”) as well as risk factors were analyzed. In all patients muscles of the lateral abdominal wall were infiltrated with 300-500 IE of botulinum toxin 4 weeks prior to the abdominal wall reconstruction. CT scans were performed before and 4 weeks after the botulinum toxin infiltration.

Results
Total of 58 patients (M/F-ratio 36:22), with a mean age of 63.8 years were included in our analysis. Mean BMI was 29.5 kg/m². Total of 50 incisional, 3 umbilical, 2 posttraumatic diaphragmatic hernias and 3 scrotal hernias were analyzed. Surgical component separation after the infiltration with botulinum toxin was necessary in 43% of the cases.

Conclusions
Preoperative infiltration of the lateral abdominal wall musculature with botulinum toxin facilitated midline reconstruction of the abdominal wall without the need for myofascial release in 57%. Reduction of surgical trauma could therefore be achieved in several patients.
P014 COMPARATIVE EFFECTIVENESS OF RESORBABLE SYNTHETIC ONLAY AND BIOLOGIC INTRAPERITONEAL MESH FOR ABDOMINAL WALL RECONSTRUCTION: A 2-YEAR MATCHED PAIR ANALYSIS

Published: December 2021

Abstract

Aim
The literature currently lacks comparative studies examining the relative effectiveness of anatomic planes and mesh selection when combating abdominal wall reconstruction (AWR), particularly when the retrorectus sublay space is not available. The aim of this study was to examine the efficacy of resorbable synthetic mesh onlay (RSOM) plane against biologic mesh in the intraperionteal plane (BIPM).

Methods
A single center, two surgeon, 5-year retrospective review (2014-2019) was performed examining subjects who underwent AWR in the onlay plane with resorbable synthetic mesh or the intraperitoneal plane with biologic mesh. A matched paired analysis was conducted. Data examining demographic characteristics, intraoperative variables, post-operative outcomes, and costs were analyzed.

Results
A total of 88 subjects (44 per group) were identified (median follow-up: 24.5 months). The mean age was 57.7 years, with a mean BMI of 30.4 kg/m2. The average defect size was 292 ± 237 cm2, with most wounds being clean-contaminated (48.9%), and 55% having prior failed repair. RSOM subjects were significantly less likely (4.5%) to experience recurrence compared to BIPM (22.7%; p&lt;0.026.). Additionally, RSOM suffered less post-operative surgical site occurrences (18.2% vs. 40.9%;p&lt;0.019) and required fewer procedural interventions (11.4% vs. 36.4%;p&lt;0.011). RSOM was also associated with significantly less total costs ($16,658 ± 14,930) compared to BIPM ($27,645 ± 16,864;p&lt;0.001).

Conclusion
When faced with hernia repair, the selection of resorbable synthetic mesh in the onlay plane may be preferable to biologic mesh place in the intraperitoneal plane due to lower long-term recurrence rates, surgical site complications, and costs.
