Resveratrol regulates Thoc5 to improve maternal immune activation-induced autism-like behaviors in adult mouse offspring

Maternal infection during pregnancy is an important cause of autism spectrum disorder (ASD) in offspring, and inflammatory infiltration caused by maternal immune activation (MIA) can cause neurodevelopmental disorders in the fetus. Medicine food homologous (MFH) refers to a traditional Chinese medicine (TCM) concept, which effectively combines food functions and medicinal effects. However, no previous study has screened, predicted, and validated the potential targets of MFH herbs for treating ASD. Therefore, in this study, we used comprehensive bioinformatics methods to screen and analyze MFH herbs and drug targets on a large scale, and identified resveratrol and Thoc5 as the best small molecular ingredient and drug target, respectively, for the treatment of MIA-induced ASD. Additionally, the results of in vitro experiments revealed that resveratrol increased the expression of Thoc5 and effectively inhibited lipopolysaccharide-induced inflammatory factor production by BV2 cells. Moreover, in vivo, resveratrol increased the expression of Thoc5 and effectively inhibited placental and fetal brain inflammation in MIA pregnancy mice, and improved ASD-like behaviors in offspring.

Comparative aspects of targeted sentinel lymph node mapping in veterinary and human medicine: opportunities for future research.

There is a significant overlap in the genetic, metabolic and epigenetic alterations between human and companion animal cancers, including those of the oral cavity, breast, bladder, skin, lungs and pancreas. In many cancer types, the identification and removal of affected lymph nodes are essential for accurate cancer management, including treatment and prognosis. Historically, lymphadenectomy and subsequent radical resection based on regional anatomy, palpation and lymph node aspirates were considered sufficient; however, modern approaches with sentinel lymph node mapping (SLN) mapping have increased the accuracy of surgical decision-making. Preoperative and intraoperative SLN mapping techniques in veterinary patients parallel those used in human medicine. While many of these techniques are highly successful, the main challenges with current methodologies are their sensitivity and specificity for the presence of cancer, which can be overcome via precision medicine and targeted SLN mapping agents. Given the large population of dogs and cats with cancer, the crossover of knowledge between species can help to deepen our understanding of many of these cancers and can be useful in evaluating new drugs and/or therapies. In this review, we discuss SLN mapping techniques in veterinary medicine and the concept of precision medicine as it relates to targeted SLN mapping imaging agents. The large number of companion animals affected by cancer is an underutilized resource to bridge the translational gap and we aim to provide a reference for the use of dogs and cats as a comparative model for human SLN mapping.

Bioinformatics database and production layout visual analysis platform of medicinal plants:a case study of Dao-di medicinal materials in Sichuan province

In the new stage of trans-omics and trans-subjects for medicinal plants, it is an urgent need to integrate big data, provide interactive applications, and form a unified and multi-level research system and big data platform. Dao-di medicinal material, as an important source of medicinal plants, is a unique quality concept and comprehensive standard of tranditional Chinese medicine(TCM). Several databases have been developed in China and abroad, such as the Encyclopedia of Traditional Chinese Medicine(ETCM) and the Global Pharmacopoeia Genome Database(GPGD). Yet, most databases do not provide multi-dimensional data, including geographic data, phenotype data, compound data, and genetic data. Sichuan, known as the hometown of TCM therapies and the treasure trove of TCM, is the most representative region of medicinal plant diversity in China. According to the latest data of the fourth national survey of TCM resources, there are more than 8 000 TCM and 86 Dao-di medicinal materials in Sichuan province. Based on resource census data and relevant achievements, this study constructed the bioinformatics database of medicinal plants and the visual analysis platform of production layout by taking the Dao-di medicinal materials in Sichuan province as an example, covering geographic data, phenotype data, compound data, and genetic data. It effectively integrates multi-dimensional data of Dao-di medicinal materials and provides different levels of data interaction applications. The platform is the first large-scale multi-dimensional database and visual platform of Dao-di medicinal materials in Sichuan province, which serves as an essential resource for germplasm resources identification, decomposition of biosynthetic pathways, molecular breeding of varieties and provides medicinal plant resource information and data support for development and utilization of medicinal plants in China and abroad.

Advances in Genetic Reprogramming: Prospects from Developmental Biology to Regenerative Medicine.

The foundations of cell reprogramming were laid by Yamanaka and co-workers, who showed that somatic cells can be reprogrammed into pluripotent cells (induced pluripotency). Since this discovery, the field of regenerative medicine has seen advancements. For example, because they can differentiate into multiple cell types, pluripotent stem cells are considered vital components in regenerative medicine aimed at the functional restoration of damaged tissue. Despite years of research, both replacement and restoration of failed organs/ tissues have remained elusive scientific feats. However, with the inception of cell engineering and nuclear reprogramming, useful solutions have been identified to counter the need for compatible and sustainable organs. By combining the science underlying genetic engineering and nuclear reprogramming with regenerative medicine, scientists have engineered cells to make gene and stem cell therapies applicable and effective. These approaches have enabled the targeting of various pathways to reprogramme cells, i.e., make them behave in beneficial ways in a patient-specific manner. Technological advancements have clearly supported the concept and realization of regenerative medicine. Genetic engineering is used for tissue engineering and nuclear reprogramming and has led to advances in regenerative medicine. Targeted therapies and replacement of traumatized , damaged, or aged organs can be realized through genetic engineering. Furthermore, the success of these therapies has been validated through thousands of clinical trials. Scientists are currently evaluating induced tissue-specific stem cells (iTSCs), which may lead to tumour-free applications of pluripotency induction. In this review, we present state-of-the-art genetic engineering that has been used in regenerative medicine. We also focus on ways that genetic engineering and nuclear reprogramming have transformed regenerative medicine and have become unique therapeutic niches.

Knowledge, Attitude, and Practice (KAP) Status toward Clinical Reasoning and Evidence-Based Medicine among the Medical Interns and Gynecology Residents of Iran University of Medical Sciences.

Clinical reasoning and evidence-based medicine (EBM) are important concepts in modern medicine. We performed this study to investigate the knowledge, attitude, and practice (KAP) status toward clinical reasoning and EBM among the medical interns and gynecology resident physicians of Iran University of Medical Sciences and related factors. A cross-sectional study (Tehran, Iran, first half of 2022) was conducted based on two researcher-made questionnaires consisting of three components for each including clinical reasoning attitude (CR-A), clinical reasoning knowledge (CR-K), clinical reasoning practice (CR-P), EBM attitude (EBM-A), EBM knowledge (EBM-K), and EBM practice (EBM-P). The related factors were age, gender, educational level, score of general practice education, having research experience, and general practice experience. A total of 60 individuals participated. The mean score was good for CR-A, moderate for CR-K, moderate for CR-P, good for EBM-A, moderate for EBM-K, and moderate for EBM-P. The total score was moderate in both clinical reasoning and EBM. Among the related factors, CR-P was associated with higher educational levels and having experience in general practice (P < 0.05). Research experience was associated with better CR-K and all KAP components for EBM (P < 0.05). The total score and many of the KAP components had moderate status for clinical reasoning and EBM. Planning on the associated factors should be regarded in the future. Such questionnaires are suggested to be validated for use in quasi-experimental studies.

A Brief Review on Essential Medicine

The World Health Organization (WHO) initially released its list in 1977, marking the beginning of the Essential Medicine Concept, a significant advancement in medical treatment. One of the most cost-effective aspects of modern healthcare is the appropriate use of vital medications. From expert judgement to evidence-based selection, the selection process has developed. In 1996, the first Indian list was published. Particularly in the public sector and in low- and lower middle-income countries, Essential Medicine Policies (EMLs) have had an impact on the provision of medications and led to a higher availability of essential vs non-essential medicines. Even yet, fair access is not guaranteed by the accessibility of necessary medications, particularly in the public sector.

Chronic rhinosinusitis with nasal polyposis and biological agents: the ARIA-ITALY Survey.

Background. Chronic rhinosinusitis (CRS) is an inflammatory disease that affects the nasal mucosa and the paranasal sinuses. CRS can be associated by nasal polyposis (CRSwNP phenotype) in up to 30% of patients and it is frequently associated with bronchial asthma. CRSwNP shows predominantly an underlying activation of type 2 inflammatory pathways with the involvement of eosinophils, IgE, interleukin (IL)-4, IL-5 and IL-13. Biological drugs that target these inflammatory cytokines are currently a therapeutic option recognized by guidelines for the treatment of uncontrolled form of the disease. Methods. As part of the activity of the "ARIA-Italy" working group, a panel of 255 Italian Ear, Nose and Throat (ENT) specialists, pneumologists and immuno-allergologists actively participated in this national survey and answered a series of questions geared toward understanding the main criteria for patient characterization and therapeutic decision, highlighting multidisciplinarity, and the implementation of the management of CRSwNP patients, as a part of the precision medicine concept and the appropriate use of the biologicals. Results. Two hundred and fifty-five experts and specialists participated in the survey. Conclusions. The results of this survey obtained from an extensive number of active specialists throughout Italy allow some important concluding remarks to be drawn. The main points of agreement were that multidisciplinary care teams provide many benefits but that, once the team is established, meetings and communication between members must be coordinated. Finally, the dissemination of national disease registries and the continuous updating of guidelines and position papers related to CRSwNP and comorbidities should be encouraged.

Adequate research helps to bridge the gaps in research and help the future generations in developing new interventions.

Peculiarities of Providing Palliative Care to Tuberculosis Patients

The data from literary sources (the electronic database of medical publications PubMed) have been summarized to highlight contemporary concepts of providing palliative care and recent statistics regarding the provision of palliative care to tuberculosis patients in Ukraine were analyzed. Objective of this analysis was to highlight problematic issues and aspects that require improvement in the field of providing palliative care to tuberculosis patients in Ukraine.The problem of tuberculosis remains relevant today. Despite significant achievements in the fight against tuberculosis, the effectiveness of treating this disease in Ukraine does not reach the target set by the WHO. The issue of drug-resistant tuberculosis remains acute. Individuals with tuberculosis and their families face a range of physical, socio-economic, and psychological challenges associated with the illness, which dimi­nish their quality of life and require a comprehensive approach to address them. Therefore, according to modern concepts, an important component of managing patients with tuberculosis, especially drug-resistant forms, is palliative care. The modern concept of palliative medicine envisions the earliest possible initiation of palliative care for patients with indications as early as possible, simultaneously with curative therapy, gradually increasing the scope of palliative care interventions until completely replacing curative treatment as the disease progresses. Early integration of palliative care for tuberculosis patients enhances the quality of life for patients and their families, promoting better adherence to etiotropic treatment.For the further development and improvement of the palliative care system for tuberculosis at the state level, the resolution of the following issues is necessary: ensuring the integration of palliative care services at all levels of medical care; strengthening and expansion of personnel potential in matters of palliative care; improvement and implementation of guidelines for integrated palliative care for tuberculosis at all levels of care; integration of palliative care into the program management system of drug-resistant tuberculosis from the first day of diagnosis; ensuring sustainable and comprehensive access of people suffering from tuberculosis to essential medicines for providing palliative care; improving the quality of providing psychological assistance to patients and their families.

Toward physics-based precision medicine: Exploiting protein dynamics to design new therapeutics and interpret variants.

The goal of precision medicine is to utilize our knowledge of the molecular causes of disease to better diagnose and treat patients. However, there is a substantial mismatch between the small number of food and drug administration (FDA)-approved drugs and annotated coding variants compared to the needs of precision medicine. This review introduces the concept of physics-based precision medicine, a scalable framework that promises to improve our understanding of sequence-function relationships and accelerate drug discovery. We show that accounting for the ensemble of structures a protein adopts in solution with computer simulations overcomes many of the limitations imposed by assuming a single protein structure. We highlight studies of protein dynamics and recent methods for the analysis of structural ensembles. These studies demonstrate that differences in conformational distributions predict functional differences within protein families and between variants. Thanks to new computational tools that are providing unprecedented access to protein structural ensembles, this insight may enable accurate predictions of variant pathogenicity for entire libraries of variants. We further show that explicitly accounting for protein ensembles, with methods like alchemical free energy calculations or docking to Markov state models, can uncover novel lead compounds. To conclude, we demonstrate that cryptic pockets, or cavities absent in experimental structures, provide an avenue to target proteins that are currently considered undruggable. Taken together, our review provides a roadmap for the field of protein science to accelerate precision medicine.

Alternative &amp; complementary medicine as career after pharmacy graduation

Alternative and complementary medicine has been derived from the natural medicine and can be considered as applied pharmacognosy. The applied pharmacognosy for patient treatment is based on Herbal Medicine concepts. The field of Alternative and Complementary medicine also includes Naturopathic Medicine which is also a part of applied pharmacognosy which the undergraduate students in pharmacy study for 4-year course. This editorial gives the legal status of such practices and career option for the pharmacist who have completed graduation in Pharmacy.

The importance of professional responsibility and fetal viability in the management of abortion.

In June 2022, the Dobbs v. Jackson Women's Health Organization Supreme Court decision ended the constitutional right to the professional practice of abortion throughout the United States. The removal of the constitutional right to abortion has significantly altered the practice of obstetricians and gynecologists across the US. It potentially increases risks to pregnant patients, leads to profound changes in how physicians can provide care, especially in states with strict bans or gestational limits to abortion, and has introduced personal challenges, including moral distress and injury as well as legal risks for patients and clinicians alike. The professional responsibility model is based on the ethical concept of medicine as a profession and has been influential in shaping medical ethics in the field of obstetrics and gynecology. It provides the framework for the importance of ethical and professional conduct in obstetrics and gynecology. Viability marks a stage where the fetus is a patient with a claim to access to medical care. By allowing unrestricted abortions past this stage without adequate justifications, such as those concerning the life and health of the pregnant individual, or in instances of serious fetal anomalies, the states may not be upholding the equitable ethical consideration owed to the fetus as a patient. Using the professional responsibility model, we emphasize the need for nuanced, evidence-based policies that allow abortion management prior to viability without restrictions and allow abortion after viability to protect the pregnant patient's life and health, as well as permitting abortion for serious fetal anomalies.

ROUTE OF ADMINISTRATION OF NANOPARTICLES COMBATING A RESISTANT BACTERIUM.

In the middle of the late century, the concept of medicine has been reshaped and reformed by the discovery of antibiotics. Untreatable infectious diseases have become treatable, However, with time microbes adapt to resist the antibiotic treatments due to their enormous adaptive ability. Therefore, new antibiotics were required to combat these resistant bacteria. But the enormous adaptive ability of bacteria has turned the next generation of antibiotics obsolete. Thus, Nanoparticles play a crucial role due to their antibacterial activity. Besides, these can act as carriers for various antibiotics to increase their efficiency against superbugs. The current review provides an in-depth overview of nanoparticles, their biosynthesis, antibacterial activity, and synergistic effects with various antibiotics.

Regional immunity involved in the maintenance and imbalance of periodontal homeostasis

The concept of homeostatic medicine has helped the researchers to understand the periodontal tissues in a completely new dimension. Periodontal tissues are subjected to complex external environmental stimuli and the internal tissues are continuously undergoing active remodeling. Periodontal regional immunity is continuously activated by local stimuli and interacts with the epithelial barrier, stromal tissue/extracellular matrix, and bone-coupled systems in a complex manner. Together, this complex network shapes the periodontal homeostasis. Under physiological conditions, moderate regional immunity relies on barrier function, intrinsic immune cells to control periodontal microbiota and maintain homeostasis. Under pathological conditions, pathogenic microbiota drive the periodontal homeostasis imbalance through over-activated regional immunity such as neutrophils, helper T (Th) 17 cells and B cells, causing periodontitis. Using the most basic immunological classification as a framework, this paper provides a systematic overview of the above mechanisms by which regional immunity regulates periodontal homeostasis, reviews the translational studies that have been carried out on homeostatic remodeling strategies targeting regional immunity, and proposes a series of periodontal homeostasis medicine research directions worth exploring, as well as potential new targets and strategies for homeostatic remodeling.

Kairos in diagnostics

Kairos has been a key concept in medicine for millennia and is frequently understood as “the right time” in relation to treatment. In this study we scrutinize kairos in the context of diagnostics. This has become highly topical as technological developments have caused diagnostics to be performed ever earlier in the disease development. Detecting risk factors, precursors, and predictors of disease (in biomarkers, pre-disease, and pre-pre-disease) has resulted in too early diagnoses, i.e., overdiagnoses. Nonetheless, despite vast advances in science and technology, diagnoses also come too late. Accordingly, timing diagnostics right is crucial. In this article we start with giving a brief overview of the etymology and general use of the concepts of kairos and diagnosis. Then we delimit kairos in diagnostics by analysing “too early” and “too late” diagnosis and by scrutinizing various phases of diagnostics. This leads us to define kairos of diagnostics as the time when there is potential for sufficient information for making a diagnosis that is most helpful for the person. It allows us to conclude that kairos is as important in diagnostics as in therapeutics.

Dentistry in the centuries: a historical overview.

The began of the dentistry as medicine's concept has a long history dating back to 7000 BCE, making it one of the earliest medical specialties. In its early days, dental diseases were often attributed to supernatural causes like "evil spirits" and "tooth worms." However, today, dentistry leverages cutting-edge technologies, including artificial intelligence, for diagnosis and treatment. This journey reflects the remarkable progress made in the field. Despite these advancements, there is still room for improvement in integrating dental knowledge and skills with medical science and engineering backgrounds. Bridging these disciplines could lead to even greater advancements in the diagnosis and maintenance of oral health. Thus, over time, it has transformed from a primitive form of medicine into a modern field that emphasizes preventative dental care, advanced diagnostics, and state-of-the-art treatment.

Common mechanisms of Wumei pills in treating ulcerative colitis and type 2 diabetes: Exploring an integrative approach through network pharmacology.

Wumei pills (WMP), a classical Chinese herbal formula, have shown efficacy in the treatment of ulcerative colitis (UC) and type 2 diabetes (T2DM). However, the underlying mechanisms by which WMP simultaneously targets these distinct diseases remain unclear. In this study, a network pharmacology approach was employed to unravel the potential molecular mechanisms of WMP in UC and T2DM treatment. This analysis provides a bioinformatics foundation for the traditional Chinese medicine concept of "treating different diseases with the same treatment." WMP was found to contain 65 active components, including flavonoids, sterols, and alkaloids, that act on 228 shared targets for UC and T2DM. Network analysis identified 5 core compounds (Quercetin, Kaempferol, beta-Sitosterol, Isocorypalmine, Stigmasterol) and 8 core proteins (AKT1, ESR1, TP53, IL6, JUN, MYC, TNF, EGFR) that play pivotal roles in the treatment of UC and T2DM by WMP. WMP exerts its therapeutic effects by modulating signaling pathways, including the NF-κB pathway, PI3K-Akt pathway, and p53 pathway. Molecular docking results indicate a strong binding affinity between core compounds and core genes. This study bridges the understanding of 2 diseases using network pharmacology and provides insights into shared therapeutic mechanisms, opening doors for further research in modern Chinese herbal formulations.

Massive Transfusion/Hemorrhage Protocols Versus Goal-Directed Bleeding Management: Science Gone Eerie?

Key questions in bleeding management are “Why does my patient bleed?” and “How to fix it?” To answer the first question, the high negative predictive value of viscoelastic testing can be used to identify coagulopathic bleeding. Accordingly, goal-directed bleeding management (GDBM) guided by viscoelastic testing has been shown to be an effective and essential part of the second pillar of patient blood management (PBM) with the aim to improve patients’ outcomes and safety. Patient’s medical and drug history – with a focus on medication with oral anticoagulants and antiplatelet drugs – are important in emergency, urgent, and elective surgery. Furthermore, risk scores have been developed and validated for traumatic and obstetric hemorrhage and can be helpful tools to predict severe hemorrhage and the need for massive transfusion. Acidosis, hypocalcemia, anemia, and hypothermia (“diamond of death in trauma”) are important basic conditions for hemostasis and good predictors of coagulopathy and should be closely monitored by blood gas analysis and corrected in bleeding patients. Earlier time to hemostasis was associated with decreased mortality in trauma studies. Therefore, GDBM aims to stop the bleeding as soon as possible and avoid the main killers in blood transfusion: Transfusion-associated circulatory overload, transfusion-related acute lung injury, transfusion-related immune modulation, and thrombosis. Thromboelastometry-guided bleeding management follows the concepts of Good Medical Practice and Precision Medicine. Here, rotational thromboelastometry (ROTEM)-guided bleeding management algorithms are using a stepwise approach based on the sequence “Treat first what kills first:” (1) Fibrinolysis management, (2) clot firmness management, (3) thrombin generation management, and (4) avoidance of hypercoagulability and thrombosis. Here, thromboelastometry can not only identify patients with hypercoagulability and increased risk of thrombosis but also ROTEM-guided bleeding management can avoid thromboembolic complications, too. This may support the idea of personalized antithrombotic therapy guided by viscoelastic testing in the postoperative period. Finally, PBM is not about blood transfusion: It is about patients’ outcomes. Accordingly, several meta-analyses based on more than 20 randomized controlled trials on the effect of viscoelastic testing-guided perioperative bleeding management did not only demonstrate a significant reduction in transfusion requirements but also a significant reduction in mortality and postoperative acute kidney injury. The reduction in postoperative acute kidney injury again has a significant impact on long-term survival. Accordingly, recent PBM guidelines recommend the implementation of viscoelastic testing-guided bleeding management algorithms with a 1B or 1A recommendation. This is also addressed in the World Health Organization policy brief about the urgent need to implement PBM in all member states in a timely manner. However, even if the number of national activities is increasing, there is still a long way to go.
