The efficacy of chitosan and silicon oxide to prevent postharvest weight loss and fungi infection in 'Valencia Late' oranges was tested. Three silicon oxide concentrations (0.1%, 0.2%, 1%) were applied as preharvest treatments. Chitosan treatments were performed at the same concentrations in postharvest fruit. Preharvest applications were carried out by tractor spraying, while fruit were submerged for 30 seconds in baths with the chitosan concentrations in the postharvest applications. In both cases, a positive control (water treatment) and negative control (fungicide) were included. Treated fruit were stored in a chamber to simulate commercial storage conditions (4 ºC, 90% RH) for 9 weeks. After this time, the weight loss and damage caused by fungi due to natural infection were evaluated. Both silicon oxide and chitosan applications were effective in controlling natural infection by Penicillium species but had no positive effect on weight loss.

Hypercalcemia in End Stage Renal Disease on Dialysis, is a frustrating complication for both medical staff and patients, and it may lead to vascular calcification, Calciphylaxis, and even aggravating cardiovascular disease, even in the absence of risk factors which can lead to early death [1], and correcting Hypercalcemia even in the absence of hyperphosphatemia is out most important to improve co-morbid conditions and reduce mortality, most common causes in end stage renal disease, includes high calcium dialysis bath, high dietary intake of Calcium rich food, exogenous intake of calcium products, or excessive intake of Vitamin D, underlying Sarcoidosis, rare causes need to be explored in resistant cases, including Vitamin A toxicosis, as being presented in this case.

Throughout global efforts to defend against the spread of COVID-19 from late 2019 up until now, one of the most crucial factors that has helped combat the pandemic is the development of various screening methods to detect the presence of COVID-19 as conveniently and accurately as possible. One of such methods is the utilization of chest X-Rays (CXRs) to detect anomalies that are concurrent with a patient infected with COVID-19. While yielding results much faster than the traditional RT-PCR test, CXRs tend to be less accurate. Realizing this issue, in our research, we investigated the applications of computer vision in order to better detect COVID-19 from CXRs. Coupled with an extensive image database of CXRs of healthy patients, patients with non-COVID-19 induced pneumonia, and patients positive with COVID-19, convolutional neural networks (CNNs) prove to possess the ability to easily and accurately identify whether or not a patient is infected with COVID-19 in a matter of seconds. Borrowing and adjusting the architectures of three well-tested CNNs: VGG-16, ResNet50, and MobileNetV2, we performed transfer learning and trained three of our own models, then compared and contrasted their differing precisions, accuracies, and efficiencies in correctly labeling patients with and without COVID-19. In the end, all of our models were able to accurately categorize at least 94% of the CXRs, with some performing better than the others; these differences in performance were largely due to the contrasting architectures each of our models borrowed from the three respective CNNs.

Malignant pericardial effusion is a usual and crucial exacerbation in malignancies. In some cases, pericardial effusion may be the first manifestation of the disease. Neoplastic pericarditis is extremely rare in thyroid cancer. Hereby, we describe the case of a 54-year-old man submitted to the hospital for chest pain and dyspnea. Clinical and radiological examinations were suggestive of pericardial effusion and mediastinal lymphadenopathy. The patient underwent pericardial drainage and surgical biopsy of a paratracheal lymph node. Pericardial biopsies were also taken. Histology study was compatible with metastatic papillary thyroid carcinoma with “signet-ring” cell morphology. Extended study of thyroid gland and function was performed and he was referred to oncologists for further treatment. Clinical presentation and histology are discussed emphasizing the rare correlation between pericardial pathology and metastatic thyroid carcinomas as the first diagnosis. Histopathologic findings of “signet-ring” cell morphology are very challenging for a differential diagnosis between thyroid carcinoma and other metastatic adenocarcinomas.

Introduction: Oxidative stress is a phenomenon induced by an imbalance between production and the biological system's ability to readily detoxify oxygen reactive species (ROS) in cells. It has been shown that grape juice can reduce oxidative stress due to the presence of polyphenols. The aim of this study was to evaluate the effect of fresh red grape juice and grape fermentative product on oxidative stress in human erythrocytes.Methods: 5 ml of blood from 125 healthy individuals as control group collected in EDTA containing tubes. To perform biochemical assays, erythrocytes were incubated at 37 ºC for different times including 4, 24, 48, and 72 hours in the presence or absence of grape juice and grape red wine in amounts of 5 ml. Results: Grape juice and grape red wine reduced lipid peroxidation and increase of thiol groups, and total antioxidant capacity after 24 hours of treatment (p < 0.05). Also, the activity of catalase enzyme was increased 4 and 24 hours after treatment with red wine and grape juice, respectively. Conclusion: Grape juice and grape fermentative product may improve the antioxidant power of erythrocytes. This may lead to reducing the risk of free-radical damage and chronic diseases. However, more research with a higher number of samples is necessary to confirm the antioxidant effect of grape juice and red wine on human erythrocytes.

Background: The novel coronavirus is a rapidly spreading respiratory disease that has been declared a pandemic by the World Health Organization (WHO) and a global public health emergency. The use of face masks has been recommended by the WHO and the Centers for Disease Control (CDC) as a standard prevention method for transmission of COVID-19.Objective: The objective of this study is to determine face mask utilization and associated factors in combating the COVID-19 pandemic among government employees in Akaki district administration offices in Akaki District, Oromia, Ethiopia, 2022Methods: A quantitative cross-sectional study was conducted from December 1, 2021, to February 15, 2022, on 385 government employees working in Akaki district administration offices. After obtaining consent from the study participants, data were collected using pretested, self-administered, and standardized questionnaires adapted from other studies. After the data was collected, it was entered into Epi info version 7.2.6, cleaned, and analyzed using SPSS version 26. A logistic regression model was computed to measure the association between the predictor and outcome variables. A p - value of.05 with a 95% CI was used as the cut-off point to declare the level of statistical significance. Results: The study showed that the magnitude of good practice for facemask utilization was 213 (53.5%) (95% CI: 1.50, 1.60) for preventing COVID-19. In the multivariate logistic regression analysis, the odds of using face masks among male employees (AOR = 0.275; 95% CI: 0.137, 0.555), employees aged 20-29 (AOR = 0.17; 95% CI: 0.065, 0.481 ), employees aged 30-39 (AOR = 0.260, 95% CI: 0.109, 0.623), employees of less than five family size (AOR = 0.549, 95% CI: 0.303, 0.995), work experience at 6-12 (AOR = 0, 32, 95 CI: 0.120, 0.450), poor knowledge about face mask use (AOR = 0.504, 95% CI: 0.302, 0.844), and employees with a negative attitude (AOR = 0.430, 95% CI: 0.256, 0.721) were factors significantly associated with face mask utilization.Conclusion: The magnitude of facemask utilization was low (53.5%) compared to other studies. The results of the study showed that age, sex, household family size, work experience, poor knowledge, and the negative attitude of employees toward facemask utilization were among the factors significantly associated with facemask utilization.

A comprehensive approach to asymptomatic adults with Wolff-Parkinson-White (WPW) pattern discovered incidentally on routine electrocardiography (ECG) is debatable. The objective of this review article is to update the most recent evidence on the management of young patients with asymptomatic WPW patterns. A substantial proportion of adults with WPW patterns on ECG may remain asymptomatic but the lifetime risk for fatal arrhythmias still exists. The inherent properties of the accessory pathway determine the risk of sudden cardiac death. A low-risk pathway is considered when the pre-excitation is intermittent on ambulatory monitoring or when it disappears completely or abruptly during exercise testing. On the other hand, a high-risk pathway in EP study is suggested by the presence of the shortest pre-excited RR interval (SPERRI) during atrial fibrillation of ≤ 250 ms or accessory pathway effective refractory period (APERP) ≤ 240 ms. The cardiac evaluation may thus be considered in asymptomatic patients with WPW to determine the individual risk for future symptomatic arrhythmia. A shared-decision making must be performed before offering catheter ablation whose procedural success rate is high.

The transfusion is a normal life-saving procedure conducted commonly by the nurses at the prescription of the attending physician or the emergency physicians. It is generally a safe procedure if guidelines for processing and administering are carefully followed. Blood transfusion is an independent risk factor for morbidity and mortality and major complications arising from transfusion are generally rare. We present a case of a mild case of iatrogenic air embolism exacerbated by pressure infusion for a patient who had undergone an exploratory laparotomy for an iatrogenic fistula repair under epidural anesthesia.

In this paper, the concentration of As, Cd, Cr, Cu, Pb, and Zn was investigated in soil and Ambrosia artemisiifolia L. sampling from polluted cite near the enterprises for the production and processing of batteries in the city of Dnipro in Ukraine. The obtained results of the study were provided to assess the plant species through bio-monitoring and phytoremediation. Though Ambrosia artemisiifolia L. is a weed that causes serious allergic reactions in humans, this plant species can also have a high bioaccumulative capacity regarding metals. The obtained results highlighted the metals’ significantly higher concentration in roots than in the inflorescence part in Ambrosia artemisiifolia L. Among all studied metals, Zn and Cu had the highest concentration in Ambrosia artemisiifolia L., while lead was characterized by the highest bioavailable content available to plant forms in the soil. The various distribution of As, Cd, Cr, Cu, Pb, and Zn was found in different parts of the plant. According to plant-up-taking indexes studied elements can be ranked in the following descending order: Cu > Zn > Cr > Cd > Pb. Ambrosia artemisiifolia L. could be proposed for phytoremediation in Zn, Cu, Cd, and Cr contaminated soils although this species is resistant to lead soil pollution.

In this short opinion piece, we discuss the appropriate use of the term ‘invasion’ for woody plant expansion and refer to the various ways in which the term is being used in the literature. We point out the present confusion and make suggestions for the use of a more appropriate term (i.e., ‘woody plant encroachment’). We continue with an overview of the various definitions of ‘woody plant encroachment in the literature, we mention associated alternative terms, and we explain the circumstances in which each of these are used. With this piece, we hope to provide more clarity on the use of correct terminology related to woody plant expansion research.

Fungus belonging to the genus Aspergillus is considered highly important in the production of various types of enzymes and organic acids. Aspergillus species produce organic acids such as citric acid, itaconic acid, and malic acid, which are one of the most important alternate techniques for chemical processes. Citric acid is an important component in the manufacturing process of food and beverages, pharmaceuticals, cosmetics, toiletries, detergents, and other industries. In this work, A.niveus was isolated from the agricultural waste collected in Kotagiri, The Nilgiris, India. Submerged batch fermentation with a range of low-cost substrates, such as wheat flour, corn starch, and sweet potato, was used to successfully synthesize citric acid by the isolated fungus. In addition, production-related factors such as substrate concentration and incubation time were optimized. The maximum yield of citric acid was produced using A. niveus from corn starch at a concentration 7of 120 g/L after 168 hours at pH 3.2. Furthermore, with a degree of extraction of 91.96, citric acid was extracted from fermentation.

It is utterly important to ensure the safety of stem cell donors and limit the incidence of long-term adverse events. Additionally, the willingness to donate the potentially life-saving stem cells, depends among other reasons, on the donor’s trust in the safety of the procedure as our case highlights. Here we present the case of a 35-year-old patient who developed macrohematuria and proteinuria following peripheral blood stem cell (PBSC) donation. 4 years later he was diagnosed with IgA-nephropathy (IgAN) and the disorder was causally attributed to the PBSC donation. He discouraged his family and friends from registering as donors because of this. In the current case report, we review the literature on the relationship between IgAN and PBSC donation and suggest under which conditions stem cell donation can still be performed even with a prior diagnosis of IgAN.

The aim of this work is to report some interesting references and documents related to the mRNA vaccine. Every cited reference can act as an instrument to better understand what some independent researchers find: this work is mainly focused on the public debate related presence/absence of graphene derivates in some vaccine vials for COVID-19. Relevant classic articles White Papers or other kinds of a document are useful instruments to better clarify some crucial aspects of this infectious disease, its epidemiology and the efficacy of the measure adopted (preventive, therapeutic, or vaccine).If the reviewed article show an intrinsic recognized international value other kinds of source like a White Paper or other documents can be of interest to generate hypotheses or to open public discussion on crucial topics. For this reason, it is useful to use this method also in the discussion related to impurity profiles in new innovative bio-pharmaceuticals like the mRNA vaccine. The fact that this product was introduced with an emergency authorization, whit reduced the time of experimentation and due to the lack of official quality information related to some raw materials used authorizes us to use also this method.Even if the international official regulatory agency does not find this substance in the control for release of the lots it is interesting to more deeply investigate what funded by an independent researcher in some vials of vaccine or sample patient’s blood after vaccination. This reference even if not a smoking gun the same can stimulate the reasoning about the general concept involved. It is needed, to read this work, to consider the intrinsic limitation of some of the study research reported (White Paper) or the other documents.

Dynamic Knee Valgus (DKV) is correlated with both, Anterior Cruciate Ligament (ACL) injury and hip and ankle disorders in female athletes and has a more significant prevalence compared with male athletes because of numerous factors. The aim of this study is to determine if the connexion between DKV, landing errors, and non-contact ACL injury and re-injury in high-performance, adult, female team sport athletes can be eliminated by changing the frontal plane movement pattern and the landing errors during the rehabilitation process (RHB), a process which was focussed on dynamic knee stability with multidimensional single-leg jump landing training, on 3D knee balance improvement and multistimulus perturbation challenges and tasks,+ eccentric & concentric exercise, strength & conditioning, aerobic training that lasted from 26 - 44 weeks.Assessing and eliminating-reducing DKV during the RHB is mandatory in lowering the re-rupture rates in female professional athletes after ACL surgery and in preventing opposite knee trauma.

The post-harvest health and microbial safety of plant products and foods continue to be a global concern to farmers, consumers, regulatory agencies and food industries. A study was carried out to evaluate the pathogenicity of fungi associated with post-harvest rot of oranges, watermelons and bananas in Lafia, Nasarawa State, Nigeria. Healthy fruits inoculated with fungal spores obtained from rotted fruit tissues were incubated at ambient temperature conditions and observed daily for the appearance and development of tissue rot. Oranges and Watermelons had the highest number of fungal isolates (3) compared to banana (2). Fungi belonging to the genus Curvularia were the most isolated (37.50%), followed by both Aspergillus and Colletotrichum (25.00% respectively) and lastly Alternaria (12.50%). The highest tissue rot diameter of sweet orange (2.40 cm) was induced by Alternaria sp. followed by Curvularia geniculate (1.40 cm) and lastly Colletotrichum sp. (1.28 cm). The highest rot of banana fruit tissues was produced by A. niger (3.90 cm), followed by Curvularia geniculate (3.40 cm). Aspergillus sp. produced the highest tissue rot diameter on watermelon fruits (1.93 cm), followed by Colletotrichum sp. (1.30 cm) and lastly Curvularia geniculate (1.20 cm). Differences in the susceptibilities of different fruits to rot by fungal pathogens were significant (p ≤ 0.05). There is need for improved handling of fruits after harvest to prevent losses due to bacterial and fungal rots in the study area.

Background: One of the types of the complex control system is medico-biological, which includes a set of methods and measures aimed at assessing the health, and functional state of the athlete’s body, taking into account the reaction of his systems to various loads. CrossFit is a constantly varied and high-intensity functional training program in which with increasing the training load, the pulse rate increases.The context and purpose of the study: The research was aimed to find out the frequency of heart rate of adolescent judokas in the presence of CrossFit-trainings in the process of physical fitness, for which a pedagogical scientific experiment was held at the youth sports and cultural training center after V. Zakaryan (Hrazdan city). From the groups of 10-12-year-olds practicing judo at the sports school, one experimental and control group was formed, each with 10 athletes. During CrossFit-trainings “Tabata”, “AMRAP”, “21-15-9” and “WOD” methods were mainly used. Athletes’ pulse rate was measured manually at the wrist before training, during training, and immediately after training in order to control the athletes’ feelings toward the training load.Results: In the September-June period, with the implementation of the CrossFit-training program, the heart rate of athletes before training was on average 102,2 bpm, during training 158,3 bpm and immediately after training – 157,8 bpm.Conclusion: The indicators obtained as a result of the research correspond to the norms suggested in literature sources.

The pandemic the new Coronavirus infection has brought changes in the health status of a large number of our citizens. The consequence of this has been a higher rate of employees seeking medical care and subsequent sick leave. Crisis phenomena in the economic and social life of society are associated with the consequences of the pandemic, moreover, the stress burden on the population increases with the consequences of the pandemic. All this affects the level of performance. The transferred COVID-19 has increased the number of patients with complaints of pain in joints and muscles, with the phenomena of cardiovascular pathology, as well as in breathing, increased frequency of asthma attacks, etc. That is, complications affected a wide range of diseases [1-4]. All this is the consequence, including neurological pathology, which is closely related to stress. According to surveys of several large industrial enterprises, 31.7% of those seeking medical help report anxiety, sleep problems, and a feeling of fatigue [5]. Exacerbation of chronic diseases was recorded in more than 50% of patients with COVID-19. The figures show that more than 1/3 of the population is chronically unwell, and more often than usual they apply for sick leave, which inevitably leads to a decrease in economic indicators [6-10].

Percutaneous coronary angioplasty is a minimally invasive procedure aimed at unclogging a coronary artery with a low complication rate (with a serious complication rate of 3% to 7% and a mortality rate of 1.2%). Device entrapment during PCI is a rare but life-threatening complication that occurs in < 1% of PCIs and balloon entrapment comes second after coronary guidewires. We present the case of 68-years-old man, smoker, hypertensive and type2 diabetic that presents angina with evidence of ischemia on myocardial tomoscintigraphy and in whom the radial coronary angiography reveals a tight calcified mid LAD stenosis. During his PCI and after dilatation with an NC balloon 2.5 × 12 the latter refuses to deflate and remains trapped in the lesion with the appearance of pain and ST-elevation despite several attempts to dilute the product in the inflator and to burst it by overexpansion. Traction on the balloon resulted in the deep intubation of the guiding-catheter, which comes in contact with the trapped balloon, and the rupture of the latter’s hypotube, which remains inflated at the site of the lesion and mounted on the 0.014 guidewire. We put a second 0.014 guidewire distally in the LAD and twisted with the distal part of the first guidewire, then we introduced a second balloon 2.0 × 20 over the second guidewire until the distal part of the guiding-catheter and inflated to trap the stucked balloon. We gradually removed this emergency assembly that allowed us to retrieve the trapped balloon. The control injection revealed a thrombotic occlusion of the LAD treated by thrombectomy and anti-GPIIbIIIa followed by a DES 2.75 × 28 placement. The patient was discharged 48 hours later with a good LVEF. The possible balloon entrapment mechanisms are an acute recoil of a highly calcified lesion with compression of the incompletely deflated balloon, which seems to be the case in our patient, strangulation of the proximal balloon end by the guiding-catheter if the balloon is removed before complete deflation and break or bend of the hypotube. The solutions in case of undeflatable balloon entrapment are to dilute the product in the inflator, to burst it by overexpansion, to pierce it through a stiff guidewire (or through its other end on a Microcatheter or OTW balloon), to cut its outer part and let it empty passively, to introduce a second guide-wire and perform a Buddy-Balloon or to transfer the patient to Surgery. Material entrapment remains a rare but life-threatening complication, its eviction requires the choice of material size and gentle manipulations (small balloons in the event of a calcified lesion) and its management uses different techniques, the choice of which depends on the clinical and anatomical situation. 

Introduction: Atrial Septal Defect (ASD) is the most common congenital heart disease, accessible to percutaneous closure in 90% of cases. The closure procedure is performed usually under local anesthesia and TTE by femoral access. The association of OS-ASD with an azygos continuation of the inferior vena cava is very rare (< 0.1/1000 births) making femoral access impossible. Only a few cases are mentioned in the literature, here we describe the procedure as faithfully as possible. Important clinical finding: We present a case of a 32-years-old female candidate for percutaneous closure of OS-ASD with right cavity dilatation who present during her procedure an unusual guidewire path suspecting an azygos continuation of the inferior vena cava, confirmed by CT angiography, making impossible the closure via the femoral approach. Therapeutic intervention: After being confronted with the categorical patient refusal of the surgery, we performed successfully the procedure; one month later; under general sedation by internal jugular approach. We finished with manual compression before extubating the patient. Outcomes: The follow-up was favorable at the cost of a hematoma at the puncture site and brachial plexus compression, which regressed after 3 days. Conclusion: We opted for general anesthesia and intubation to guide the procedure by TEE. We placed it in the aorta, which gave us good stability to continue successfully the procedure. We underestimated the risk of complication at the puncture site, which could have been avoided by using a vascular suture device or more prolonged compression. Main takeaway lesson: Percutaneous closure is the reference treatment for OS-ASD. In case of is associated with an azygos continuation of the inferior vena cava, the right internal jugular vein remains a reasonable approach; it requires discussion and rigorous preparation by the whole team. The management of the puncture site in this situation remains delicate and requires great concentration. 

Aim: To evaluate the hemodynamic changes and side effects during endotracheal intubation with Macintosh laryngoscope and intubating laryngeal mask airway.Materials and methods: A prospective, simple randomized, comparative study on 100 patients 18 years - 60 years of age, divided into two groups: Group A comprising intubation with Macintosh laryngoscope and Group B intubation through ILMA.Results: Total intubation time (in seconds) of group A was 24.38 + 3.26 seconds and of the group, B was 42.94 + 1.24 seconds. At 2,4 and 6, a higher rise in mean heart rate was noted in group A (p < 0.05). At 2,4,6 and 8 minutes difference in mean SBP and mean DBP of the two groups was statistically significant with a p - value of < 0.05 with a significant increase of mean SBP and mean DBP in patients of group A. The difference for all complications was not significant between the two groups.Conclusion: Intubation via intubating laryngeal mask airway can be done as an alternative to direct laryngoscopy using a Macintosh blade as intubation via intubating laryngeal mask airway has shown to have lesser hemodynamic changes.
