Neurodegenerative disorders (NDDs) pose a significant global health challenge, impacting millions with a gradual decline in neurons and cognitive abilities. Presently, available NDD therapies focus on symptom management rather than altering the disease trajectory. This underscores the critical necessity for groundbreaking treatments capable of addressing the root causes of neurodegeneration, offering both neuroprotection and neuro-restoration. This in-depth review delves into the forefront of emerging NDD therapies, encompassing gene therapy, stem cell therapy, immunotherapy, and neurotrophic factors. It sheds light on their potential advantages, hurdles, and recent advancements gleaned from both preclinical and clinical studies. Additionally, the document outlines existing NDD treatments, spanning pharmacological and non-pharmacological interventions, along with their inherent limitations. The overarching conclusion emphasizes the immense potential of emerging therapies in NDD treatment, yet underscores the imperative for continued research and optimization to ensure their safety, efficacy, and specificity.

Ischemia-Reperfusion Injury (IRI) is the outcome of two intertwined pathological processes resulting from the shortage of blood flow to tissues and the subsequent restoration of circulation to a previously ischemic area. IRI (sometimes just one side of the dyad) remains one of the most challenging problems in several branches of emergency medicine. Mitochondrial and endoplasmic reticulum dysfunction is a crucial pathological factor involved in the development of IRI. The sigma-1 receptor (Sig1-R) is an intracellular chaperone molecule located between the mitochondria and endoplasmic reticulum with an apparent physiological role in regulating signaling between these cell organelles and serves as a safety mechanism against cellular stress. Therefore, amelioration of IRI is reasonably expected by the activation of the Sig1-R chaperone. Indeed, under cellular stress, Sig1-R agonists improve mitochondrial respiration and optimize endoplasmic reticulum function by sustaining high-energy phosphate synthesis. The discovery that N, N-dimethyltryptamine (DMT) is an endogenous agonist of the Sig1-R may shed light on yet undiscovered physiological mechanisms and therapeutic potentials of this controversial hallucinogenic compound. In this article, the authors briefly overview the function of Sig1-R in cellular bioenergetics with a focus on the processes involved in IRI and summarize the results of their in vitro and in vivo DMT studies aiming at mitigating IRI. The authors conclude that the effect of DMT may involve a universal role in cellular protective mechanisms suggesting therapeutic potentials against different components and types of IRIs emerging in local and generalized brain ischemia after stroke or cardiac arrest.

The genesis of the youth Community Health Worker (CHW) and Citizen/Community Science (CS) training is rooted in interdisciplinary research and the lived experiences of families in Chicago and Urbana-Champaign. Dr. Mendenhall and colleagues’ (Drs. Robinson, Roberts and Rodriquez-Zas) South Chicago’s Black Mothers’ Resiliency Project provide dinsights into Black women’s experiences with genomics, trauma, and community science. Black women’s testimonies highlighted the health impacts of living in neighborhoods with high levels of gun violence and the resilience strategies they employ. This led to the development of a youth-centered CHW and CS training program, aimed at addressing health disparities. The program trained high school students and young adults (up to age 24) as CHWs and CSs, focusing on the objectives of (1) embedding culturally competent health workers in marginalized communities; (2) amplifying community voices; (3) collecting, analyzing, and quantifying observational data to inform policy decision-making; (4) amplifying community voices in healthcare discussions and (5) creating community health care worker training certification for youth. Over three years, the program trained over 50 participants, incorporating elements of wellness, art, and entrepreneurship.Based on ethnographic notes participants reported increases in wellness such as reduced anxiety and increased empowerment. The program’s long-term goals include creating employment opportunities for graduates and contributing to improved community health outcomes. This initiative represents a step towards addressing racial trauma and promoting community healing through youth-led innovation and empowerment.

The present review highlights some of the very important contributions to non-alignment ways of comparing biological sequences, which may be genome sequences of nucleotides, protein sequences of amino acids, or sequences of protein secondary structures. The discussion centers around specific methods applicable to the comparison of three types of sequences. The methods of comparison of genome sequences are based on three pairs of biological groups of nucleotides; the same for protein sequences are based on either physio-chemical property values of amino acids or on classified groups of amino acids of different cardinalities obtained from the physio-chemical properties; the same for sequences of secondary structures of proteins are based on their sequential expressions of structure elements of cardinality three and four. Comparison is made in the time domain and also in the frequency domain. Different taxa of known phylogeny are considered for comparison. It tries to find out the specific method of comparison, which can show the exact phylogeny of the taxa. If a new sequence appears in the database, it becomes essential to know its phylogeny. For this purpose, a phylogenetic tree is drawn on the sequences of the known taxa together with this new sequence using the best possible method. If the species having this new sequence belongs to the old taxa, there is nothing to worry about. Otherwise, the species with the new sequence has to be studied separately. This is the general reason for the construction of a phylogenetic tree in any form of biological sequence comparison.

The Blood Flow Restriction (BFR) technique is based on cuffs connected to a pressure device that induces partial arterial inflow. BFR combined with exercise has already been proven to increase strength, muscle mass, and muscular endurance. However, some BFR devices with pneumatic air bands, such as KAATSU (KA), are expensive and less accessible, making either a Sphygmomanometer Cuff (SC) or Elastic Band (EB) an interesting alternative. However, vascular parameters in response to blood flow restriction during KA, EB, and SC have not yet been compared. Purpose: The aim of this study was to compare the brachial blood flow behavior during restriction using bands such as KA, SC, and EB on the same perceived tightness. Methods: Thirty healthy men participated in a prospective crossover study. Participants underwent blood flow measurements before and during KA, SC, and EB use, with KA-perceived tightness taken as a reference. The brachial blood flow volume, the diameter of the artery, and blood flow velocity were measured before and immediately after the cuff’s inflation at a specific tightness. Results: Blood flow volume was significantly reduced in KA (52%, ES: 1.38), SC (61.7%, ES: 1.29), and EB (41.5%, ES: 1.22) (p

Loneliness is thean experience that is intertwined inwith being human, but since it is so painful and troubling, all of us try to avoid it. It has short- and long-term negative consequences, including its influence on our life satisfaction, health, and mortality. Various causal factors were explored regarding loneliness, which is essentially a subjective experience. This commentary aims to highlight the contribution of culture, be it collectivistic or individualistic, to the development of loneliness. Since loneliness is correlated with the expectation of being with others and part of a community, research found that people in collectivistic cultures are lonelier than those in individualistic ones. Ethnicity also contributes to the development, and was thus reviewed. While it beingis an essential part of being human, loneliness can, indeed, be attenuated and its pain lessened, and culture may predict ways of doing so.

DNA evidence has now become an essential part of forensic investigations since it offers vital information for person identification and crime resolution. However, the biological material is affected by some environmental factors which may impact the DNA in biological samples. This may affect the correctness and reliability of forensic DNA analysis. This review is related to the influence of various environmental conditions on the stability and degradation of DNA in biological stains including blood and saliva stains. The common factors that affect DNA are temperature, humidity, exposure to sunlight, and type of substrate. The information is crucial to improve forensic DNA analysis and forensic protocol optimization. The DNA stability and integrity in biological materials, such as blood and saliva stains, are indispensable for forensic DNA analysis. Environmental influences, however, significantly affect DNA concentration and may jeopardize forensic analysis. The present review explores various environmental factors for their effect on DNA stability in blood and saliva stains. While DNA degradation is slowed but not completely prevented by low temperatures, it is accelerated by high temperatures. Risks of contamination arise from the promotion of microbial growth and DNA breakdown by humidity. DNA photodamage brought on by sunlight exposure results in strand breakage and cross-linking. DNA stability is also influenced by the type of substrate used; porous surfaces, such as cloth, are better at keeping fluids than non-porous ones, such as glass. Maintaining the integrity of DNA evidence requires an understanding of these variables. The present studies will help to create sophisticated DNA preservation methods for use in forensic DNA examination. The study emphasizes the requirement of improvement in forensic DNA analysis skills, related to the preservation of DNA pieces of evidence and the possible effect of environmental factors.

Introduction: Post-dilution online hemodiafiltration is the most efficient extracorporeal depurative treatment of CKD. Recently a new type of membrane has been developed, with a higher cut-off point also called a medium cut-off point, which has the capacity to eliminate higher molecular weight molecules in hemodialysis. The hemodialysis performed with these membranes has been called “Expanded Hemodialysis”.Objective: Compare the purifying efficacy of medium and high molecular weight molecules in patients dialyzed with high-flux hemodialysis, VitaPES 210HF, and with patients treated with expanded hemodialysis with the medium cut-off dialyzer, Elisio-HX.We also assessed the effect that the increased removal of inflammatory mediators by MCO hemodialysis had on fecal Calprotectin levels.Patients and methods: This is a prospective observational cross-over study in which 8 prevalent hemodialysis patients were followed for two months. Blood levels of IL-6, C-reactive protein (CRP), β2-microglobulin, Kappa and Lambda immunoglobulin light chains, and serum albumin were determined before and after each hemodialysis session.Results: The percentage of reduction of medium and higher molecular weight molecules: β2microglobulin, IL-6, Kappa and Lambda chains and CRP were higher with the Elisio-21HX dialyzer compared to the VitaPES 210HF dialyzer. There was no difference in albumin clearance between the two dialyzers.Fecal calprotectin levels were lower in patients dialyzed with Elisio-21HX.Conclusion: The medium cutoff dialyzer, Elisio-HX, is more efficient in the elimination of medium/high molecular weight molecules than the VitaPES HF high-flux dialyzer, with the same albumin elimination.Improving inflammation at the local intestinal level with lower levels of fecal Calprotectin.

Rheumatic heart disease persists as a significant concern in developing regions, often resulting in multivalvular heart conditions. Treatment options are limited, though percutaneous transvenous mitral commissurotomy effectively addresses rheumatic mitral stenosis. Non-surgical interventions for aortic stenosis include balloon aortic valvotomy and Transcatheter aortic valve replacement (TAVR), tailored to patient factors like age and comorbidities.We describe two cases of Rheumatic multivalvular disease which were managed non-surgical. The first case is a pioneering procedure performed on a young patient combined percutaneous transvenous mitral commissurotomy with balloon aortic valvotomy, guided by 4-dimensional transoesophageal echocardiography (4D TEE). This represents the first documented instance in medical literature, showcasing the potential of integrated interventions and advanced imaging techniques. In the second challenging case involving a heavily calcified, retrovirus, and Hepatitis B positive 55-year-old, a staged approach was adopted, involving percutaneous transvenous mitral commissurotomy followed by Transcatheter aortic valve replacement (TAVR). Despite complexities, this sequential strategy demonstrates the adaptability of transcatheter techniques in managing complex valvular pathologies. These cases highlight the evolving landscape of interventional cardiology and underscore the importance of tailored, multidisciplinary approaches in optimizing outcomes for patients with rheumatic heart disease and multivalvular involvement, especially in resource-limited settings. Further exploration and dissemination of such innovative strategies hold promise for enhancing cardiac care quality and expanding treatment options globally.

Juvenile Xanthogranulomatosis (JXG) is a condition, characterized by a proliferation of histiocytes, primarily observed in infants and young children. Cutaneous manifestations appear as yellow-orange-brown papules or nodules, typically localized on the face, neck, and upper chest. While most lesions regress spontaneously, some may require intervention for aesthetic, diagnostic, or hemorrhagic reasons. A rare case of disseminated JXG in a child with hemophilia has been reported. In this patient with severe hemophilia A, cutaneous nodules appeared, some associated with bleeding requiring appropriate management. Treatment included the administration of factor VIII to prevent bleeding during surgical procedures and secondary prophylaxis, to control recurrent bleeding. The outcome was favorable with the disappearance of the cutaneous lesions without sequelae, under regular surveillance for both medical conditions. This case highlights the rare association between juvenile xanthogranulomatosis (JXG) and hemophilia, a combination that has never been documented in the medical literature. This association only impacts the management of JXG when the cutaneous lesions bleed and their excision becomes necessary.

A 51-year-old female with a history of multinodular goitre presented with vomiting, abdominal discomfort, and generalized tiredness. Investigations revealed hypercalcemia (ionized calcium 1.41 mmol/L), hypokalaemia, suppressed parathyroid hormone, and significantly elevated free thyroxine (> 7.77 ng/dL) with a suppressed thyroid-stimulating hormone level consistent with hyperthyroidism. Further, the workup confirmed Graves’ disease as the underlying aetiology. Hyperthyroidism is occasionally associated with mild to moderate hypercalcemia, but severe hypercalcemia or hypercalcaemic crisis is an extremely rare complication. Prompt recognition and treatment are crucial to prevent life-threatening complications. The patient was treated with intravenous fluids, a low-calcium diet, zoledronic acid, carbimazole, and a beta-blocker, leading to improvement in her condition. This case highlights a rare occurrence of hypercalcaemic crisis in a patient with thyrotoxicosis due to Graves’ disease. Hyperthyroidism-induced hypercalcemia requires prompt recognition and multidisciplinary management involving endocrinologists, internists, and critical care specialists to prevent potentially life-threatening complications. Healthcare providers should consider the hypercalcaemic crisis in the differential diagnosis of hypercalcemia in the context of hyperthyroidism.

Background: Maternal mortality is a very sensitive indicator of our health system and services. Epidemiological data about maternal mortality is a vital requirement in every setting not only to design interventional programs but also to identify gaps in the existing structures, to reduce the ratio favorably. This study was an attempt to shed light on the mortality rate in our hospital, to analyze the epidemiological aspects, causes of maternal mortality, and types of delay, and to suggest recommendations for improvement. Methods: A retrospective study was done at a tertiary care center at the district level from January 2022 to December 2022. Demographic data and details of selected parameters were obtained from maternal death review forms and case records. Data analyzed and presented.Results: The majority of the maternal deaths could be attributed to direct obstetric causes like Eclampsia (29.41%), Pre-eclampsia (20.59%), and anemia (20.59%) followed by hemorrhage (14.71%), and septicemia (11.76%). Medical conditions contributing to death included liver disorders (5.8%), COVID-19 infection (5.8%), and cardiac disorders (2.9%). Conclusion: It is evident that the maternal mortality ratio is significantly high, with a majority of the deaths occurring due to avoidable causes. Leading contributory factors were due to delay in seeking help or delay in referral. High-risk cases must be identified at the earliest and referred to higher centers for management from the first trimester itself. Generating awareness among the common public and counseling the gravidas and their caretakers throughout pregnancy is equally important to prevent maternal mortality and near-miss cases.

This paper investigates the effect of coating concentration (ppm), and coating thickness (µm) on the anti-microbial properties of polycarbonate sheets using a variety of anti-microbial agents (Cu-infused Mg(OH)2, Mg(OH)2, Cu(OH)2, MgO, CuCl2.2H2O, and ZnO). In addition, a complete analysis was performed for all agents to rank the best agent in terms of the highest anti-microbial performance against E. coli K-12 MG1655 in two time intervals (4 and 24 hours). The coating concentration (ppm) was found to be a significant factor in the anti-microbial characteristics for Cu-infused Mg(OH)2, Mg(OH)2, Cu(OH)2, MgO, CuCl2.2H2O, and ZnO (p = 0.004, p < 0.0001, p < 0.0001, p = 0.0297, p = 0.0011, and p = 0.0130 respectively). The coating thickness (µm), on the other hand, was found to be a major contributor to the anti-microbial properties of Cu-infused Mg(OH)2, Mg(OH)2, Cu(OH)2, MgO, and CuCl2.2H2O (p < 0.0001, p = 0.0004, p = 0.0011, p = 0.0310, and p < 0.0001 respectively). The analysis determined that the coating did not influence the anti-microbial properties of ZnO. The interaction between the coating concentration (ppm), and the coating thickness (µm) was found to be a significant factor for Cu-infused Mg(OH)2, Cu(OH)2, MgO, CuCl2.2H2O, and ZnO (p < 0.0001, p = 0.0001, p = 0.0004, p < 0.0001, and p < 0.0001 respectively), however, this was not a significant factor for Mg(OH)2.Highlights•    The anti-microbial activity of the inorganic material is dependent on the particle shape and size.•    Particles with sharp edges will provide additional physical injuries to the microorganisms.•    Smaller particle size will provide higher surface area therefore better interaction with microorganisms.•    The coating concentration and coating thickness will be crucial to the anti-microbial activity.•    The thermal embossing techniques demonstrate good adhesion to the surface.

Introduction: Immune checkpoint inhibitors (ICI) have significantly improved cancer treatment outcomes, but cardiovascular complications such as ICI-associated myocarditis are a major concern. Diagnosing myocarditis requires integrating biomarkers, electrocardiogram (EKG), cardiac imaging, and endomyocardial biopsy. We present a case illustrating these diagnostic challenges, involving a female patient treated with pembrolizumab who developed fatal acute myocarditis mimicking infiltrative cardiomyopathy.Case report: A 54-year-old woman with mucosal melanoma, treated with pembrolizumab, was hospitalized in May 2023 due to dyspnea and elevated troponin levels. Initial cardiac workups were normal, but subsequent tests revealed borderline cardiac magnetic resonance imaging findings. In late May 2023, the patient was admitted with worsening dyspnea, elevated NT-pro-BNP, and severe hyperlactatemia. Imaging and endomyocardial biopsy confirmed acute myocarditis with atypical presentation, mimicking infiltrative cardiomyopathy. Despite aggressive immunosuppressive therapy, the patient’s condition deteriorated, resulting in cardiogenic shock and death seven days post-admission.Conclusion: This case underscores the diagnostic and management challenges of ICI-associated myocarditis, particularly with atypical presentations. It highlights the need for vigilant, comprehensive monitoring and further research to improve diagnostic and therapeutic strategies for managing these severe side effects in patients undergoing ICI therapy.

This study presents a novel approach to calculating the average change in kinetic energy of galaxies exhibiting non-relativistic motion. The methodology integrates the dynamics of total observed motion, which encompasses both peculiar and recessive motion, with the gravitational influence of neighboring galaxies. The peculiar motion is quantified through peculiar redshift, while recessive motion is described by Hubble’s Law. The total observed velocity is the sum of these two components. The research derives an expression for the average acceleration of a galaxy based on the change in its total observed redshift wavelength over time. Utilizing Newton’s Second Law of Motion, the average observed force and subsequent work done by this force is calculated. The work done by conservative forces, primarily gravitational forces exerted by neighboring galaxies, is also considered to determine the total work done on the galaxy. Results indicate that the average total observed force causing the motion of a galaxy is a non-conservative force, resulting from the combined effects of non-conservative forces responsible for peculiar and recessive motion. The change in potential energy due to gravitational interactions with neighboring galaxies is accounted for, leading to the formulation of the average change in kinetic energy. The conclusion of the paper provides a comprehensive expression for the average change in kinetic energy of a galaxy, factoring in the mass of the galaxy, the speed of light, the total observed redshift, the change in distance with respect to Earth, and the gravitational constant. This expression is significant for understanding the dynamics of galactic motion and the forces at play in a non-relativistic context.

An empirical framework that accurately describes radioactive binding energies is the Somewhat Empirical Mass Equation (SEMF). They showcase many implementations and uses of the idea that rely on graphics and printed objects. A key new addition is a contrast with real experiments, as well as a visualization of the energy environment as supplied by the SEMF. The shortcomings of the empirical theory are shown by our visualization of this differential energy scenery, which also highlights the significance of what is known as magic numbers—an explanation provided by the outermost approach, which was developed much more recently than the water drop theory. This provides a great chance to talk about the advantages and limitations of simulations everywhere within the framework of science teaching.

Ischemic Heart Disease (IHD) remains a significant cause of morbidity and mortality worldwide. We present a case report of a 54-year-old individual presenting with symptoms suggestive of IHD, including palpitations and chest heaviness. Utilizing a Spandan device at home, the patient detected anteroseptal and lateral wall ischemia, prompting consultation with a cardiologist. Subsequent diagnostic evaluations revealed Left Ventricular Hypertrophy (LVH), concentric LVH, regional wall motion abnormality, and Grade I diastolic dysfunction. Hypertension and dyslipidemia were identified as prominent risk factors, with additional findings of carotid artery disease. Management strategies included antihypertensive medications, lipid-lowering therapy, and lifestyle modifications. This case underscores the complexity of diagnosing and managing IHD, highlighting the importance of comprehensive assessment and multidisciplinary care in optimizing patient outcomes.
