Herbal Medicinal

With tens of thousands of plant species on earth, we are endowed with an enormous wealth of medicinal remedies from Mother Nature. Natural products and their derivatives represent more than 50% of all the drugs in modern therapeutics. Because of the low success rate and huge capital investment need, the research and development of conventional drugs are very costly and difficult. Over the past few decades, researchers have focused on drug discovery from herbal medicines or botanical sources, an important group of complementary and alternative medicine (CAM) therapy. With a long history of herbal usage for the clinical management of a variety of diseases in indigenous cultures, the success rate of developing a new drug from herbal medicinal preparations should, in theory, be higher than that from chemical synthesis. While the endeavor for drug discovery from herbal medicines is “experience driven,” the search for a therapeutically useful synthetic drug, like “looking for a needle in a haystack,” is a daunting task. In this paper, we first illustrated various approaches of drug discovery from herbal medicines. Typical examples of successful drug discovery from botanical sources were given. In addition, problems in drug discovery from herbal medicines were described and possible solutions were proposed. The prospect of drug discovery from herbal medicines in the postgenomic era was made with the provision of future directions in this area of drug development.

The recent legalization of Cannabis sativa L. in many regions has revealed a need for effective propagation and biotechnologies for the species. Micropropagation affords researchers and producers methods to rapidly propagate insect-/disease-/virus-free clonal plants and store germplasm and forms the basis for other biotechnologies. Despite this need, research in the area is limited due to the long history of prohibitions and restrictions. Existing literature has multiple limitations: many publications use hemp as a proxy for drug-type Cannabis when it is well established that there is significant genotype specificity; studies using drug-type cultivars are predominantly optimized using a single cultivar; most protocols have not been replicated by independent groups, and some attempts demonstrate a lack of reproducibility across genotypes. Due to culture decline and other problems, the multiplication phase of micropropagation (Stage 2) has not been fully developed in many reports. This review will provide a brief background on the history and botany of Cannabis as well as a comprehensive and critical summary of Cannabis tissue culture. Special attention will be paid to current challenges faced by researchers, the limitations of existing Cannabis micropropagation studies, and recent developments and future directions of Cannabis tissue culture technologies.

History Of

Over the past 60 years, the use of crystals to define structures of complexes using X-ray analysis has contributed to the discovery of new medicines in a very significant way. This has been in understanding not only small-molecule inhibitors of proteins, such as enzymes, but also protein or peptide hormones or growth factors that bind to cell surface receptors. Experimental structures from crystallography have also been exploited in software to allow prediction of structures of important targets based on knowledge of homologues. Crystals and crystallography continue to contribute to drug design and provide a successful example of academia–industry collaboration.

State Of The Field

In this volume marking the thirtieth anniversary of Muqarnas, the Editor reflects on the evolution of the journal over the years. To that end, the members of the Editorial and Advisory Boards were sent a questionnaire, asking them to comment on the contributions of Muqarnas and its Supplements series to the field of Islamic art and architecture studies over the past three decades, and to provide suggestions for future directions. Their observations, thoughts, and hopes for Muqarnas have been anonymously incorporated into this essay, which, in conversation with their comments, looks back on the history of the publication and offers some possibilities for the path it might take going forward.
The goal here is neither to assess the historiography nor to examine the current state of the field thirty years after the opening essay of volume 1. Instead, the focus is on the development and impact of both Muqarnas and the Supplements series in a highly specialized field with relatively few and short-lived or sporadic journals, before turning to the successes and shortcomings of these publications, as outlined by some of the board members.

Role Of Women

This Introduction outlines the need for a ‘true history’ (Lerner 1976) of the role of women in the history of linguistics, which considers them on their own terms, and challenges categories and concepts devised for traditional male-dominated accounts. We start by considering what research has already been conducted in the field, before exploring some of the reasons for the relative dearth of studies. We outline some of the challenges and opportunities encountered by women who wished to study the nature of language and languages in the past. The geographical and chronological scope of this volume is then discussed. In a central section we examine some of the major recurring themes in the volume. These include attitudes towards women’s language, both positive and negative; women and language acquisition and teaching; and women as creators of new languages and scripts. We further explore women as authors, dedicatees, or intended readers of metalinguistic texts, as interpreters and translators, and as contributors to the linguistic documentation and maintenance. We consider how women supported male relatives and colleagues in their endeavours, sometimes in invisible ways, before reviewing the early stages of their entry into institutionalized contexts. The chapter concludes with a brief section on future directions for research.

Cell Signaling Pathways

Virtual screening, or VS, is emerging as a valuable tool in discovering new candidate inhibitors for many biologically relevant targets including the many chemotherapeutic targets that play key roles in cell signaling pathways. However, despite the great advances made in the field thus far, VS is still in constant development with a relatively low success rate that needs to be improved by parallel experimental validation methods. This chapter reviews the recent advances in VS, focusing on the range and type of computational methods and their successful applications in drug discovery. The chapter also discusses both the advantages and limitations of the various techniques used in VS and outlines a number of future directions in which the field may progress.

Treatment of brain cancers, especially high grade gliomas (WHO stage III and IV) is slowly making progress, but not as fast as medical researchers and the patients would like. Immunotherapy offers the opportunity to allow the patient's own immune system a chance to help eliminate the cancer. Immunotherapy's strength is that it efficiently treats relatively small tumors in experimental animal models. For some patients, immunotherapy has worked for them while not showing long-term toxicity. In this paper, we will trace the history of immunotherapy for brain cancers. We will also highlight some of the possible directions that this field may be taking in the immediate future for improving this therapeutic option.

Harmful Effects

Herbal medicine has become popular in recent years as an alternative medicine. The problem arises when herbal medicines contain an undeclared synthetic drug that is illegally added, since it is a natural product that does not contain any chemical drugs due to the potential cause of harmful effects. Supervision of herbal medicines is important to ensure that these herbal medicines are still safe to use. Thus, developing a reliable analytical technique for the determination of adulterated drugs in herbal medicine is gaining interest. This review aims to provide a recent analytical method that has been used within the past 5 years (2016–2021) for the determination of chemical adulterants in herbal medicine.

Lung disease has been a leading cause of significant morbidity and mortality since neonates first drew breath. Over the past few decades, many treatment options have evolved to aid us in our ability to support neonatal breathing. The history of neonatal pulmonary care, both its successes and controversies, can teach us a great deal about the future of this dynamic field. As new developments occur, we constantly modify the therapies we offer to preterm and term infants. Understanding traditional therapeutic options and knowing what may be on the horizon can help caregivers to better match treatment plans with individual infants. This article reviews advances in mechanical ventilation, adjuvant therapies, and respiratory drugs through the past few decades and speculates on future directions in this field.
