One of the primary constraints in upland rice cultivation is the disease blast (Magnaporthe oryzae), which can provide reduction up to 100% of the grain yield The use of silicon with beneficial microorganisms (bioagents) can be an alternative for the control of this disease and to provide an increase in the productivity of the rice grain. The objective of this work was to study the effect of rates of silicon with bioagents in blast suppression and grain yield of upland rice. The methodology used was tests carried out in field conditions, in two different areas: Capivara and Palmital farms, during the growing season 2015/2016. The experimental design was in a split-plot scheme with four replications. In the main plots were the silicon fertilization rates (0, 2, 4 and 8 ton ha-1) and in the subplots was the bioagents (1-without bioagents, 2-Pseudomonas fluorescens, 3-Burkholderia pyrrocinia, 4-Trichoderma asperellum, 5-a mixture of the three bioagents). The results showed that the use of 2 ton ha-1 of silicon with a mixture of bioagents was the best treatment to control leaf blast. Besides, from rates, 2 to 6 ton ha-1 of silicon in Capivara Farm and up to 8 ton ha-1 of silicon in Palmital Farm provided the highest grain yield. A mixture of bioagents provided the highest grain yield. In this sense, it was concluded that the best recommendation to connect blast control, grain yield and reduced amount of silicon was the use of 2 ton ha-1 of silicon with the mixture of bioagents.
Background: Stunting is a condition of growth and development disorders in children under 5 years of age who appear shorter than their age caused by nutritional deficiencies. The stunted growth and development of children can be influenced by deficiencies in the intake of macronutrients such as protein and micronutrients such as calcium, phosphorus, zinc, and vitamin D. One nutrient that is relevant to current dental health research is vitamin D. Objective: This review article will further analyze the relationship between vitamin D deficiency and Porphyromonas gingivalis bacterial lipopolysaccharide in stunting children. Literature review: Vitamin D deficiency can cause various problems related to the oral cavity such as a decrease in salivary flow rate, buffer capacity, and salivary content such as protein. A decrease in salivary flow rate causes secretory Immunoglobulin A (IgA) to decrease, thus disrupting the colonization of normal microflora in the oral cavity. Reduced vitamin D levels can potentially increase the number of Porpyhromonas gingivalis bacteria and also lipopolysaccharides (LPS), thus inhibiting the proliferation and differentiation of alveolar bone cells. Conclusion: Therefore, lack of micronutrient intake such as vitamin D deficiency can trigger the growth of Porphyromonas gingivalis bacteria and an increase in bacterial products such as lipopolysaccharides, especially in stunted children.
The outbreak of COVID-19 has created an unprecedented situation that has accelerated online education in areas like nephrology, which are traditionally served by onsite training. Efforts to educate clinicians remotely provide convenience and flexibility but may leave many open questions when it comes to how well-trained professionals maybe after completing their programs online. This review paper has emphasized the deleterious effects of online nephrology education and identified a number of ways in which it can be problematic such as lack of hands-on training, less patient interface, lack of proper supervision, and inconsistent quality of programs. The ability to make a difference, however, is further restricted by technological barriers and resource constraints. Whilst these programs tend to focus on creating knowledgeable graduates, they often fail to provide the clinical exposure necessary for preparedness. Hybrid programs - which combine online courses with clinical training in person are required to deliver high-quality nephrology care.

Bilateral trigeminal neuralgia refractory to medical therapy is a rare occurrence and it is mandatory to choose therapeutic procedures minimizing possible bilateral sensitive deficit due to the employment of bilateral mininvasive ablative techniques. A patient affected by bilateral trigeminal neuralgia refractory to medical therapy secondary to multiple sclerosis is presented. Multiple therapeutic tools were employed in this challenging pathology. The second and third left trigeminal divisions were involved by the neuralgia, while the third division was involved in the right facial side. Controlled radiofrequency thermocoagulation was employed for the isolated right third division, then radiosurgery was conducted for the left hemifacial side. After one month, because of the persistence of pain attacks of the left second trigeminal division, peripheral authorizations were performed. Control of pain, with the withdrawal of medical therapy (BNI scale class I), was achieved in this patient with a multi-therapeutic approach. Radiofrequency thermorizotomy was performed for the right third division because neuralgia was very acute, and immediate pain relief was achieved. Pain in the left third trigeminal division regressed after radiosurgery, while pain in the left second division continued after radiosurgery, then peripheral alcoholization was performed with pain control.Bilateral trigeminal neuralgia refractory to medical therapy should be treated by the dedicated neurosurgeon, avoiding bilateral ablative techniques for the same division and using neurosurgical techniques according to the trigeminal division interested by the neuralgia and according to the intensity of pain.
Post-transplant malignancy is one of the contentious and feared consequences of Solid Organ Transplantation (SOT), which might detrimentally alter the outcome of transplantation. Risk factors are manifold, principally related to a suppressed immune system with intercurrent immunosuppressant medications commonly used in the context of SOT. Opportunistic viral infections encountered in SOT are crucial promoters of mitogenic proliferation in several common tumors. Lastly, immune suppressant therapy might trigger mitogenic changes directly.In this paper, we are discussing post-SOT malignancies, elaborating on the different phases of its pathogenesis, and elucidating on the different aspects that linger in its risk factors, preventive strategies, and management.

Alginate, a naturally occurring biopolymer extracted from brown algae, presents a promising avenue for developing sustainable and efficient membranes for wastewater treatment. This review comprehensively examines recent advancements in the fabrication, modification, and application of alginate-based membranes for effective water purification. The paper delves into various fabrication techniques, including casting, electrospinning, and 3D printing, which influence the structural and functional properties of the resulting alginate membranes. To enhance performance, strategies such as crosslinking, incorporation of porogens, and surface functionalization are employed. These modifications optimize crucial properties like mechanical strength, porosity, selectivity, and antifouling resistance. Furthermore, Response Surface Methodology (RSM) has emerged as a valuable tool for systematically optimizing fabrication parameters, enabling researchers to identify optimal conditions for achieving desired membrane characteristics. The integration of alginate membranes with biological treatment processes, such as phycoremediation (utilizing microalgae) and mycoremediation (employing fungi), offers a synergistic approach to enhance wastewater treatment efficiency. By immobilizing these microorganisms within the alginate matrix, their bioremediation capabilities are amplified, leading to improved pollutant degradation and nutrient removal. In conclusion, alginate-based membranes demonstrate significant potential as a sustainable and effective technology for wastewater treatment. Continued research and development, focusing on optimizing fabrication processes and exploring innovative integration strategies with biological systems, will further advance the application of alginate membranes in addressing the pressing global challenge of water pollution.
Mitochondria are essential intracellular organelles that significantly influence various cellular processes, including metabolism, stress response, and cell fate. Their precise regulation is crucial for maintaining both organelle and cellular homeostasis. Wound healing is a complex, multifactorial process that relies on the coordinated actions of multiple cell types and numerous cellular mechanisms. Dysregulation in this process can lead to chronic wounds, which pose substantial challenges for healthcare systems and present limited treatment options due to their intricate pathogenesis. Recent research has increasingly focused on the role of mitochondria in wound healing, revealing their involvement in critical processes such as metabolism, apoptosis, and redox signaling. Mitochondrial dynamics play a vital role in wound healing by adapting to cellular demands and environmental cues. Moreover, mitophagy, the selective degradation of damaged mitochondria, is crucial for maintaining mitochondrial integrity and function during the healing process. Mitochondria are not only pivotal in energy production but also in calcium homeostasis and the generation of mitochondrial reactive oxygen species, which are essential for signaling during wound repair. As wound healing progresses through distinct yet overlapping stages mitochondria facilitate the energy demands of repair and contribute to cytoskeletal remodeling necessary for wound closure. Understanding the multifaceted roles of mitochondria in wound healing could lead to novel therapeutic approaches for chronic wounds. Future research should prioritize investigating mitochondrial dynamics and functions in human tissues to develop targeted strategies for enhancing wound healing outcomes.

We reviewed our outcomes of patients with relapsed/refractory Hodgkin Lymphoma treated with autologous stem cell transplant over a 30-year period, 1992 to 2022 and are reporting 15-year Disease-Free Survival (DFS) and Overall Survival (OS) of the 36 patients treated (19 men, 17 women, median age 41). Over the years there were different preparative regimens employed (carmustine, etoposide, melphalan and BCNU, etoposide, cytarabine, and melphalan) as well as post-transplant consolidation therapy (brentuximab). With a median follow-up of 15 years, the DFS is 52% and OS is 64%. Long-term complications include cardiomyopathy and second malignancies.The use of better salvage regimens and post-transplant consolidation therapy should lead to better outcomes.

Lower extremity edema is one of the most common complaints among pregnant patients. Lymphatic origin to these edemas is rarely considered and few cases of lymphedema after pregnancy have been reported and documented in medical literature. We describe here a series of 15 cases where the diagnosis of lymphedema was established by lymphoscintigraphy. Dermal reflux was observed in ten of the 15 patients (66%), popliteal lymph nodes in 11 (73%), and the edematous limb(s) were said to be abnormal in all but one case which showed only functional asymmetry at rest and limited vascular reflux in a calf.
