Published: January 2023

Society's demand for foods with high organoleptic and nutraceutical quality requires studies that identify superior cultivars and nutritional management that provides gains in quality attributes. The attributes pH, soluble solids (SS), titratable acidity (TA), SS/TA ratio, total contend of flavonoids (FVT), anthocyanins (ATC), phenols compounds (TPC), vitamin C (Vit C) and total antioxidant activity (TAA) of pseudofruits of two cultivars of short days (Pircinque and Jônica) and two of neutral days (Albion and San Andreas) submitted to spraying with water or nutrients (PAN) (B, Zn and B + Zn) under semi-hydroponic system in Alto Vale do Itajaí/SC, Brazil. Pseudofruits from short-day cultivars have higher SS content and SS/AT ratio. PAN does not influence pH, SS, AT and SS/AT ratio. Strawberries from Jônica and Albion stand out for their high Vit C content. The application of Zn increases Vit C of the cultivars. The variation found in the levels of FVT, ATC and TAA, is mainly due to the genetics of each cultivar. The TAA correlated positively with the FvT and ATC content and negatively with SS. Higher TAA were observed in decreasing order for San Andreas, Jônica, Albion and Pircinque. Pircinque strawberries are sweeter, with higher SS and SS/AT ratio, but with lower TAA.
On graphs with α- and b-edge consecutive edge magic labelings
Authors: Barrientos Christian
Published: January 2023

Among the most studied graph labelings we have the varieties called alpha and edge-magic. Even when their definitions seem completely different, these labelings are related. A graceful labeling of a bipartite graph is called an α-labeling if the smaller labels are assigned to vertices of the same stable set. An edge-magic labeling of a graph of size n is said to be b-edge consecutive when its edges are labeled with the integers b+1, b+2, ..., b+n, for some 0 ≤ b ≤ n. In this work, we prove the existence of several b edge-magic labelings for any graph of order m and size m-1 that admits an α-labeling. In addition, we determine the exact value of b induced by the α-labeling, as well as for its reverse, complementary, and reverse complementary labelings.
On the number of caterpillars
Authors: Barrientos Christian
Published: January 2023

A caterpillar is a tree obtained from a path by attaching pendant vertices. The number of caterpillars of size n is a well-known result. In this work extend this result exploring the number of caterpillars of size n together with the cardinalities of the stable sets and the diameter. Three closed formulas are presented, giving the number of caterpillars of size n with: (i) smaller stable set of cardinality k, (ii) diameter d, and (iii) diameter d and smaller stable set of cardinality k.
HIV-1 is Transported into the Central Nervous System by Trafficking Infected Cells
Authors: Kincer Laura , Schnell Gretja , Swanstrom Ronald , Miller Melissa , Spudich Serena , Eron Joseph , Price Richard , Joseph Sarah
Published: January 2023

Background: In this work, we carried out a cross-sectional study examining HIV-1 and HCV free virus concentrations in blood and cerebrospinal fluid (CSF) to determine whether HIV-1 enters the central nervous system (CNS) passively as virus particles or in the context of migrating infected cells. If virions migrate freely across the blood-cerebrospinal fluid barrier (BCSFB) or the blood-brain barrier (BBB) then HCV and HIV-1 would be detectable in the CSF at proportions similar to that in the blood. Alternatively, virus entry as an infected cell would favor selective entry of HIV-1.
Methods: We measured HIV-1 and HCV viral loads in the CSF and blood plasma of 4 co-infected participants who were not on antiviral regimens for either infection. We also generated HIV-1 env sequences and performed phylogenetic analyses to determine whether HIV-1 populations in the CSF of these participants were being maintained by local replication.
Results: While CSF samples taken from all participants had detectable levels of HIV-1, HCV was not detectable in any of the CSF samples despite participants having HCV concentrations in their blood plasma, which exceeded that of HIV-1. Further, there was no evidence of compartmentalized HIV-1 replication in the CNS (Supplementary Figure 1). These results are consistent with a model where HIV-1 particles cross the BBB or the BCSFB within infected cells. In this scenario, we would expect HIV-1 to reach the CSF more readily because the blood contains a much greater number of HIV-infected cells than HCV-infected cells.
Conclusions: HCV entry into the CSF is restricted, indicating that virions do not freely migrate across these barriers and supporting the concept that HIV-1 is transported across the BCSFB and/or BBB by the migration of HIV-infected cells as part of an inflammatory response or normal surveillance.

Published: January 2023

Introduction: Hypotension is an acute complication following Emergency Endotracheal Intubation (ETI) in populations who called the Rapid Response Team (RRT). Thus, a fast and simple tool is needed to identify the risk of Post-emergency Intubation Hypotension (PIH). Shock Index (SI) pre-intubation is one of the potential factors to predict PIH. Objective: To measure the association between shock index with post-emergency intubation hypotension after calling for the RRT. Materials and Methods: This research is a cohort retrospective study that analyzed 171 patients aged ≥18 years who have called RRT and underwent an emergency ETI. The cut-off point for SI was determined using the ROC curve to predict PIH. The modification effect was evaluated using stratification analysis. Data were analyzed using cox regression to determine the likelihood of SI in the cause of hypotension. Result: A total of 92 patients (53.8%) underwent post-emergency intubation hypotension. The SI cut-off point of 0.9 had a sensitivity of 82.6% and a specificity of 67.1% for predicting PIH (Area Under Curve (AUC) 0.81; 95% CI 0.754–0.882, p <0.05). The increased risk of PIH associated with high SI score was an aRR of 1.9; 95% CI 1.03–3.57, a p-value of 0.040 among those with sepsis, and an aRR of 7.9, 95% CI 2.36–26.38, a p-value of 0.001 among those without sepsis. Conclusion: This study showed that a high SI score was associated with PIH after being controlled with other PIH risk variables. The risk of PIH associated with SI score modestly increased (2-fold increase) in those with sepsis and significantly increased (8-fold increase) in those without sepsis.
Using Multimodal Analgesia for Breakthrough Pain in Stage IV Breast Cancer Patient
Authors: Wijaya Indriyani , Mahmud
Published: January 2023

Introduction: Breakthrough Pain (BTP) is experienced as mild to moderate-severe pain, from only a few seconds to hours. It causes a decrease in the quality of life and functional capacities. Furthermore, BPT must be recognizable, assessed, and controlled to prevent its relapse and severity. Case report: A woman, 45 years old, having breast cancer along with pulmonary, femur, and cervical metastases, came with the main complaint of pain. The patient had a pain score of NRS 9, which was felt intermittently for the last 3 months. Treatment has been carried out with MST 10 mg/8 hours and a Durogesic® patch (fentanyl 50 mcg/h) but the pain did not subside. Moreover, the patient was unable to identify any precipitating factors or pain relievers, while the diagnosis confirmed BTP. The rescue dose was administered in a range of 10 – 20% of the total daily dose in the last 24 hours equivalent to 11 – 22 mg intravenous Morphine or equianalgesic with 110 – 220 mcg of fentanyl. For immediate effect, transmucosal fentanyl was recommended, but this preparation is currently unavailable. Moreover, therapy was carried out with the continuous administration of Morphine, and the pain reduced to NRS 0 – 3 on the second day. Conclusion: Transmucosal fentanyl, either buccal, sublingual, oral, or nasal mucosa, was proven to be effective in treating BTP. However, when transmucosal fentanyl is not available, multimodal analgesia is an effective alternative.

Published: January 2023

Introduction: Heart disease is one of the most common causes of maternal death. The incidence has increased since women with congenital and acquired heart disease reached fertile age. The circulation system changes during pregnancy which are induced by changes in the progesterone. The changes in progesterone levels increase heart work and cause death in pregnant women. Objective: This report aims to elaborate on the administration of nitrates as the management of labor in rheumatic heart disease (RHD). Case Report: A 27-year-old woman complained of shortness of breath and wanted to give birth. The patient was 38 weeks pregnant and had a history of heart disease. Antero-posterior chest radiography examination showed pulmonary edema and cardiomegaly. The patient was examined using echocardiography before spontaneous labor and was diagnosed as pregnant with rheumatic heart disease. As an emergency management, the patient was given painless spontaneous labor. The patient was given nitrates on the first day after delivery as a treatment for progesterone withdrawal syndrome in this case. After the delivery process was completed, the patient was admitted to the Intensive Care Unit (ICU). Discussion: Progesterone hormone produced by the corpus luteum and the placenta until the eighth week of pregnancy and before delivery, respectively, can reduce systemic vascular resistance. Progesterone hormone increase causes peripheral vasodilation by affecting the function of endothelial nitric oxide synthase (eNOS) and nitrite oxide (NO) production. Conclusion: A pregnant woman with rheumatic heart disease can be given exogenous nitrate. Administration of exogenous nitrates in this patient successfully prevent the reduction of peripheral vascular resistance and postpartum hemodynamic instability because it can replace the reduction in nitric oxide caused by progesterone withdrawal.
Regional Anesthesia Subarachnoid Blockade (RASAB) in Scoliosis Patients
Authors: Setijanto Eko , Putra Kiel Pino
Published: January 2023

Introduction: Scoliosis is a three-dimensional spinal deformity that is mainly determined based on the lateral curvature of the spine. Furthermore, regional anesthesia often infiltrates the peripheral nerves with an anesthetic agent and blocks transmission to avoid or relieve pain. A previous study revealed that scoliosis in patients is one of the factors affecting the success of spinal anesthesia. Objective: To obtain a theoretical basis that can support the solution to the RASAB problem. The acceptance of the theory is the first step to providing a better understanding of the study problem based on the scientific framework of thinking. Furthermore, the similarities, differences, and views of several pieces of literature that discussed related issues were evaluated in this review. Review: Regional anesthesia subarachnoid blockade (RASAB) or spinal anesthesia, is a procedure, which involves the administration of local anesthetic drugs into the subarachnoid space. Furthermore, the process is carried out between the lumbar (L) vertebrae L2-L3, L3-L4, or L4-L5. Spinal anesthesia is often used in surgical procedures involving the lower abdomen, pelvis, perineum, and lower extremities. Summary: In the setting of scoliosis, spinal anesthesia is challenging, but is not an absolute contraindication. Patients with scoliosis have unique characteristics, hence, anesthetists need to understand the impact of the disease on the body.

Проблематика. Рання діагностика раку молочної залози має колосальне значення, оскільки дана патологія є одним із найбільш розповсюджених чинників летальності серед жінок по всьому світу. Чи не небезпечнішим підтипом раку молочної залози вважається інвазивна протокова карцинома. Зазвичай патологоанатоми фокусуються на областях з подібною карциномою, так як це дозволяє присвоїти оцінку агресивності усьому зразку монтування. Саме тому важливою задачею є автоматизоване виявлення карциноми при діагностиці ракових пухлин молочної залози.
Мета. Встановлення основних етапів побудови діагностичних алгоритмів класифікації типу ракової пухлини молочної залози на основі аналізу гістологічних знімків.

Published: January 2023

Nano cellulose has the advantages of high degree of polymerization, high strength, degradability, and large specific surface area. The modifier is uniformly dispersed in the matrix material to form a composite system containing nano-scale materials in one phase. With regard to the above-mentioned competitive situation of performance fibers, China should first strengthen the research on engineering scale-up, focusing on finding the factors that affect product quality and dispersion coefficient from engineering issues, and making continuous improvements. Using the analytic hierarchy process method, according to the idea of first decomposition and then synthesis, through pairwise comparison between risk indicators, the risk weights of risk factors at various levels in the risk assessment index system are rigorously calculated and sorted, and the degree of membership and validity are compared. The risk assessment index is judged, the fuzzy clustering algorithm is used to identify the bad data in the market competition data, and the conditional value-at-risk (CVaR) model is constructed to conduct risk assessment. Experimental results show that the actual logarithmic rate of return fluctuates around 0, most of which are higher than the Va R value. Only in extreme cases will it break the Va R curve; the accuracy of risk assessment is close to 100%, and the (Tech-Sector Volatility)TSV indicator begins to decline significantly. That is, the transmission sensitivity of risk data is effectively improved.
On the Koopman representation of Hamiltonian flows in infinite dimensional spaces with invariant measure
Authors: Glazatov Vladimir Andreevich , Sakbaev Vsevolod Zhanovich
Published: January 2023

We study Hamiltonian flows in a real separable Hilbert space endowed with a symplectic structure. Measures on a Hilbert space that are invariant with respect to flows of completely integrable Hamiltonian systems and allow one to describe Hamiltonian flows in a phase space in terms of unitary groups in the space of functions squarely integrable with respect to an invariant measure are studied. The properties of the Koopman representation are described using the example of the Hamiltonian of a countable set of noninteracting harmonic oscillators. A spectral analysis of the generator of Koopman group for such a Hamiltonian is carried out. An invariant subspace of strong continuity of Koopman unitary group is described in terms of spectrum of the generator.

The aim of the present study was to identify and assess the determinants of the content of Ca, Mg, Zn, Fe, Cd, and Pb in longissimus lumborum (LL) and semimembranosus (SM) muscles of fallow deer and red deer reared in the organic system. The concentrations of 6 elements (Ca, Mg, Zn, Fe, Cd, Pb) in fallow deer and red deer meat produced in the organic system in Poland were analyzed with the use of inductively coupled plasma mass spectrometry. The animals, i.e. 12 ca. 2- and 3-year-old fallow deer (Dama dama) and 12 ca. 3- and 4-year-old red deer (Cervus elaphus), were culled during the autumn season. Both groups of animals comprised 6 males and 6 females. A significant effect of the species on the content of selected minerals in the meat was noted. It was found that the LL muscle from the fallow deer was a rich source of Ca, Mg, and Zn, and the meat from the red deer had high amounts of Zn and Fe. The age of the animals had a significant effect on the level of Mg in the red deer meat.

The use of digital kinematic analysis in veterinary medicine provides great opportunities to diagnose lameness in dogs. The aim of the study was to determine the lateralization of the dog's gait and to create a gait model for a given individual at walk and trot. The material used for the study was a boxer bitch. The study was carried out on a dogPACER treadmill at feed speeds allowing the dog to move at walk and trot. The analysis performed in the Noraxon MyoVideo program included the length of the step and angulation in the joints in the three phases of movement. A comparative analysis of the angle values in the joints in both gait types indicates statistically significantly larger angulation (P < 0.05) in the joints of the pelvic and thoracic limbs and a reflection of these changes in the distance between the steps taken. Deviations are most often visible for the left hip, knee and ankle joints and intensify when the gait rate increases in the initial phase of limb transfer. In addition to differences for the pelvic limbs, significant differences were found for angulation in the shoulder and elbow joints. The results indicate the advantages of kinematic analysis as a tool for early diagnosis of changes in the locomotor apparatus, which allows the implementation of appropriate therapy aimed at restoring the normal motor functions of the body.

The widespread availability of legal pneumatic weapons is commonly abused to hurt animals. Determining the shotgun based on animal injuries is complex and requires the knowledge of gunshot wounds and animal tissues. In this study, a detailed gunshot wound analysis was conducted on bird carcasses. An attempt was made to examine damaged soft and hard tissues in Japanese quail. A ballistic device of low energy was used. It was found that the shot of an average velocity of 83 m · s–1 thoroughly penetrates a bird carcass of an average mass of 205.5 g. A head or a neck shot with the same velocity can lead to immediate death. The shot velocity of 110 m · s–1 generates enough energy to move a carcass. These prove how dangerous the weapon is when used to harm small animals. Further studies may contribute to creating a model of bird injuries produced by various shots and result in strict law on possession of low-energy pneumatic weapons in Poland.

The development of infection in the field of surgical intervention is inextricably linked with financial costs and the public reputation of the institution. The medical and preventive institution needs to allocate additional funds from the hospital budget for diagnostic studies, as well as for medicines for the treatment of frolicking purulent-septic complications. As a result, medical and preventive institutions experience annual additional economic losses. P u r p o s e of the study is to assess the economic damage caused to medical and preventive institutions due to the development of infections in the field of surgical interventions. M a t e r i a l s a n d m e t h o d s . In the course of this study, an analysis of domestic and foreign literature sources on the issue of economic damage from purulent-septic complications in surgical practice was carried out. R e s u l t s . The damage caused by the development of infections in the area of surgical intervention is quite significant, and even the introduction of new technologies and therapies does not relieve patients from their possible appearance. The estimated costs of infection of the surgical intervention area vary depending on the region, the type of operation and the degree of infection. Economic analysis in this case is necessary to study the activities of organizations from the point of view of evaluating their work in order to monitor and subsequently better manage the processes of supplying the institution itself with material resources, as well as the use of internal reserves and their rational use. F i n d i n g s . The distribution of funds in medical and preventive facilities should be carried out rationally to ensure the full-fledged activity of the institution. In the absence of measures taken to prevent the development of nosocomial infections, infections of the surgical intervention area may occur after a certain period of time after the patient is discharged from the hospital, thereby contributing to the spread and contamination of healthy people, which from a socio-economic point of view is unprofitable.
