    Ratification of the Trans-Pacific Partnership (TPP) will attract a large number of foreign drug companies in the coming years to Vietnam. It is anticipated to bring investment to Vietnam's pharmaceutical industries, lead to increased infrastructure and enable the use of more sophisticated technologies for the discovery, development and manufacture of drugs. However, with respect to pharmaceutical companies, which are producing generic drugs primarily, the availability of biologic will be reduced. Thus, the consequence is, an increase in drug cost resulting in difficulties for patients wishing to procure these drugs. This will be particularly detrimental for developing countries, such as Vietnam and Malaysia.

    Neurological disorders (ND) have affected a major part of our society and have been a challenge for medical and biosciences for decades. However, many of these disorders haven't responded well to currently established treatment approaches. The fact that many active pharmaceutical ingredients can't get to their specified action site inside the body is one of the main reasons for this failure. Extracellular and intracellular central nervous system (CNS) barriers prevent the transfer of drugs from the blood circulation to the intended location of the action. Utilizing nanosized drug delivery technologies is one possible way to overcome these obstacles. These nano-drug carriers outperform conventional dosage forms in many areas, including good drug encapsulation capacity, targeted drug delivery, less toxicity, and enhanced therapeutic impact. As a result, nano-neuroscience is growing to be an intriguing area of research and a bright alternative approach for delivering medicines to their intended action site for treating different neurological and psychiatric problems. In this review, we have included a short overview of the pathophysiology of neurological diseases, a detailed discussion about the significance of nanocarriers in NDs, and a focus on its recent advances. Finally, we highlighted the patented technologies and market trends, including the predictive analysis for the years 2021-2028.

    BACKGROUND: Nummular eczema may mimic diseases that present with annular configuration and the differential diagnosis is broad.

    OBJECTIVE: This article aimed to provide an update on the evaluation, diagnosis, and treatment of nummular eczema.

    METHODS: A PubMed search was performed in using the key terms "nummular eczema", "discoid eczema", OR "nummular dermatitis". The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. The search was restricted to English literature. The information retrieved from the above search was used in the compilation of the present article. Patents were searched using the key terms "nummular eczema", "discoid eczema", OR "nummular dermatitis" in www.google.com/patents and www.freepatentsonline.com.

    RESULTS: Nummular eczema is characterized by sharply defined, oval or coin-shaped, erythematous, eczematous plaques. Typically, the size of the lesion varies from 1 to 10cm in diameter. The lesions are usually multiple and symmetrically distributed. Sites of predilection include the lower limbs followed by the upper limbs. The lesions are usually intensely pruritic. The diagnosis is mainly clinical based on the characteristic round to oval erythematous plaques in a patient with diffusely dry skin. Nummular eczema should be distinguished from other annular lesions. Dermoscopy can reveal additional features that can be valuable for correct diagnosis. Biopsy or laboratory tests are generally not necessary. However, a potassium hydroxide wet-mount examination of skin scrapings should be performed if tinea corporis is suspected. Because contact allergy is common with nummular eczema, patch testing should be considered in patients with chronic, recalcitrant nummular eczema. Avoidance of precipitating factors, optimal skin care, and high or ultra-high potency topical corticosteroids are the mainstay of therapy. Recent patents related to the management of nummular eczema are also discussed.

    CONCLUSION: With proper treatment, nummular eczema can be cleared over a few weeks, although the course can be chronic and characterized by relapses and remissions. Moisturizing of the skin and avoidance of identifiable exacerbating factors, such as hot water baths and harsh soaps may reduce the frequency of recurrence. Diseases that present with annular lesions may mimic nummular eczema and the differential diagnosis is broad. As such, physicians must be familiar with this condition so that an accurate diagnosis can be made, and appropriate treatment initiated.

    Access to affordable drugs for the treatment of HIV/AIDS and other diseases is increasingly challenging in many developing countries such as Brazil, South Africa, and India. These challenges are in part the result of strengthened patent laws mandated by the 1994 Trade-Related Aspects of Intellectual Property Rights (TRIPS) treaty. However, there are underutilized instruments within TRIPS that governments can use to limit the adverse effects of patent protection and thereby ensure a supply of affordable generic drugs to their people. One such instrument is compulsory licensing, which allows generic manufacturers to produce pharmaceutical products that are currently subject to patent protection. Compulsory licensing has been used by a number of countries in the last few years, including the United States, Canada, Indonesia, Malaysia, Brazil, and Thailand, and is particularly significant for countries such as India, where large numbers of people are infected with HIV. This Article explores the feasibility of compulsory licensing as a tool to facilitate access to essential medicines within the current patent regime in India, drawing on the experiences of other countries.

    Lauritz Toft (1920-1991), also known as Lau, graduated with a MSc degree in pharmacy at the Royal Danish School of Pharmacy in 1944. During the education and parallel activities Lau had shown gifts for intuition and improvisation, together with special talents for leadership and large-scale working. In 1945 he got the idea during the organization of the East Asiatic Company Ltd. to sell the best of the products from the Danish pharmaceutical companies in India under a common trade mark: DUMEX (Danish United Medical Export). The article describes Lau's difficulties and problems in realizing this idea. The adventure peaks in the mid-1950's with about 40 pharmacists in DUMEX-departments in India as well as Thailand, Malaysia, Indonesia, China etc.

    BACKGROUND: Polyhydroxyalkanoates are bio-based, biodegradable naturally occurring polymers produced by a wide range of organisms, from bacteria to higher mammals. The properties and biocompatibility of PHA make it possible for a wide spectrum of applications. In this context, we analyze the potential applications of PHA in biomedical science by exploring the global trend through the patent survey. The survey suggests that PHA is an attractive candidate in such a way that their applications are widely distributed in the medical industry, drug delivery system, dental material, tissue engineering, packaging material as well as other useful products.

    OBJECTIVE: In our present study, we explored patents associated with various biomedical applications of polyhydroxyalkanoates.

    METHOD: Patent databases of European Patent Office, United States Patent and Trademark Office and World Intellectual Property Organization were mined. We developed an intensive exploration approach to eliminate overlapping patents and sort out significant patents.We demarcated the keywords and search criterions and established search patterns for the database request. We retrieved documents within the recent 6 years, 2010 to 2016 and sort out the collected data stepwise to gather the most appropriate documents in patent families for further scrutiny.

    RESULTS: By this approach, we retrieved 23,368 patent documents from all the three databases and the patent titles were further analyzed for the relevance of polyhydroxyalkanoates in biomedical applications. This ensued in the documentation of approximately 226 significant patents associated with biomedical applications of polyhydroxyalkanoates and the information was classified into six major groups. Polyhydroxyalkanoates has been patented in such a way that their applications are widely distributed in the medical industry, drug delivery system, dental material, tissue engineering, packagingmaterial as well as other useful products.

    CONCLUSION: There are many avenues through which PHA & PHB could be used. Our analysis shows patent information can be used to identify various applications of PHA and its representatives in the biomedical field. Upcoming studies can focus on the application of PHA in the different field to discover the related topics and associate to this study.We believe that this approach of analysis and findings can initiate new researchers to undertake similar kind of studies in their represented field to fill the gap between the patent articles and research publications.

    OBJECTIVE: To explore tobacco industry accounts of its use of indirect tobacco advertising and trademark diversification (TMD) in Malaysia, a nation with a reputation for having an abundance of such advertising.
    METHODS: Systematic keyword and opportunistic website searches of formerly private tobacco industry internal documents made available through the Master Settlement Agreement.
    RESULTS: 132 documents relevant to the topic were reviewed. TMD efforts were created to advertise cigarettes after advertising restrictions on direct advertising were imposed in 1982. To build public credibility the tobacco companies set up small companies and projected them as entities independent of tobacco. Each brand selected an activity or event such as music, travel, fashion, and sports that best suited its image. RJ Reynolds sponsored music events to advertise its Salem brand while Philip Morris used Marlboro World of Sports since advertising restrictions prevented the use of the Marlboro man in broadcast media. Despite a ban on tobacco advertisements in the mass media, tobacco companies were the top advertisers in the country throughout the 1980s and 1990s. The media's dependence on advertising revenue and support from the ruling elite played a part in delaying efforts to ban indirect advertising.
    CONCLUSION: Advertising is crucial for the tobacco industry. When faced with an advertising ban they created ways to circumvent it, such as TMDs.

    PMID: 27185502
    BACKGROUND: Predicting the effects of genetic modification is difficult due to the complexity of metabolic net- works. Various gene knockout strategies have been utilised to deactivate specific genes in order to determine the effects of these genes on the function of microbes. Deactivation of genes can lead to deletion of certain proteins and functions. Through these strategies, the associated function of a deleted gene can be identified from the metabolic networks.

    METHODS: The main aim of this paper is to review the available techniques in gene knockout strategies for microbial cells. The review is done in terms of their methodology, recent applications in microbial cells. In addition, the advantages and disadvantages of the techniques are compared and discuss and the related patents are also listed as well.

    RESULTS: Traditionally, gene knockout is done through wet lab (in vivo) techniques, which were conducted through laboratory experiments. However, these techniques are costly and time consuming. Hence, various dry lab (in silico) techniques, where are conducted using computational approaches, have been developed to surmount these problem.

    CONCLUSION: The development of numerous techniques for gene knockout in microbial cells has brought many advancements in the study of gene functions. Based on the literatures, we found that the gene knockout strategies currently used are sensibly implemented with regard to their benefits.

    BACKGROUND: Nanosuspensions are colloidal systems consisting of pure drug and stabilizers, without matrix or lyophilized into a solid matrix. Nanosuspensions improve the solubility of the drug both in the aqueous and organic phases. Nanosuspensions are also known as brick dust molecules, as they increase the dissolution of a system and improve absorption.

    METHODS: Extensive information related to nanosuspensions and its associated patents were collected using Pub Med and Google Scholar.

    RESULTS: Over the last decade nanosuspensions have attracted tremendous interest in pharmaceutical research. It provides unique features including, improved solubility, high drug loading capacity, and passive targeting. These particles are cost-effective, simple, and have lesser side effects with minimal dose requirements. However, the stability of nanosuspensions still warrants attention.

    CONCLUSION: Nanosuspensions play a vital role in handling the numerous drug entities with difficult physico-chemical characteristics such as solubility and can further aid with a range of routes that include nasal, transdermal, ocular, parenteral, pulmonary etc. This review highlights the relevance of nanosuspensions in achieving safe, effective and targeted drug delivery.

    Sarawak, on the island of Borneo, is known internationally for its rich rain forests, flora and fauna. Its rain forests, occupying two-thirds of its geographical area shelters 2500 tree species, 5500 flowering plants and over 20 000 different kinds of animals and insects. Such abundance of plants, and in particular, in the variety thereof, have attracted the attention of scientists involved in the field of research into their potential medicinal value. Recent discovery that two species of Calophyllum tree in the rain forests of Sarawak produce active anti-HIV agents, has, no doubt, intensified interest in the State's plant resources for scientific research.

    Symptomatic slow-acting drugs for osteoarthritis (SYSADOAs) are recommended for the medium- to long-term management of knee osteoarthritis (OA) due to their abilities to control pain, improve function and delay joint structural changes. Among SYSADOAs, evidence is greatest for the patented crystalline glucosamine sulfate (pCGS) formulation (Mylan). Glucosamine is widely available as glucosamine sulfate (GS) and glucosamine hydrochloride (GH) preparations that vary substantially in molecular form, pharmaceutical formulation and dose regimen. Only pCGS is given as a highly bioavailable once-daily dose (1500 mg), which consistently delivers the plasma levels of around 10 μmol/L required to inhibit interleukin-1-induced expression of genes involved in the pathophysiology of joint inflammation and tissue destruction. Careful consideration of the evidence base reveals that only pCGS reliably provides a moderate effect size on pain that is higher than paracetamol and equivalent to non-steroidal anti-inflammatory drugs (NSAIDs), while non-crystalline GS and GH fail to reach statistical significance for pain reduction. Chronic administration of pCGS has disease-modifying effects, with a reduction in need for total joint replacement lasting for 5 years after treatment cessation. Pharmacoeconomic studies of pCGS demonstrate long-term reduction in additional pain analgesia and NSAIDs, with a 50% reduction in costs of other OA medication and healthcare consultations. Consequently, pCGS is the logical choice, with demonstrated medium-term control of pain and lasting impact on disease progression. Physician and patient education on the differentiation of pCGS from other glucosamine formulations will help to improve treatment selection, increase treatment adherence, and optimize clinical benefit in OA.

    The objective of this paper is to assess the attitude of Malaysian stakeholders to genetically modified (GM) salmon and to identify the factors that influence their acceptance of GM salmon using a structural equation model. A survey was carried out on 434 representatives from various stakeholder groups in the Klang Valley region of Malaysia. Public attitude towards GM salmon was measured using self-developed questionnaires with seven-point Likert scales. The findings of this study have confirmed that public attitudes towards GM salmon is a complex issue and should be seen as a multi-faceted process. The most important direct predictors for the encouragement of GM salmon are the specific application-linked perceptions about religious acceptability of GM salmon followed by perceived risks and benefits, familiarity, and general promise of modern biotechnology. Encouragement of GM salmon also involves the interplay among other factors such as general concerns of biotechnology, threatening the natural order of things, the need for labeling, the need for patenting, confidence in regulation, and societal values. The research findings can serve as a database that will be useful for understanding the social construct of public attitude towards GM foods in a developing country.

    Topical application of honey to burn and wounds has been found to be effective in controlling infection and producing a clean granulating bed. It is suggested that the wound healing effect of honey may in part be related to the release of inflammatory cytokines from surrounding tissue cells, mainly monocytes and macrophages. It has been reported that honey hastens wound healing by accelerating wound contractions. Microscopic evaluation demonstrated that there was a significant acceleration of dermal repair in wound treated with honey. Macroscopic and microscopic observations under in vivo assessment suggested that the topical application of honey might have favourable influences on the various phases of burn and wound healing hence accelerating the healing process. The regulatory effects of honey are related to components other than the sugars. However, the mechanisms by which honey affects the release of anti inflammatory agents and growth factors from monocytic cells are as yet unclear. Whether honey affects other cell types, particularly endothelial cells and fibroblasts, involved in wound healing also needs to be clarified. The present article is a short review of recent patents on the healing effect of honey in wound and burn management.

    Introduction: Pulmonary route is one of the preferred routes for the administration of therapeutically active agents for systemic as well as localized delivery. Chronic obstructive pulmonary disease (COPD), bronchial asthma, pneumonia, pulmonary hypertension, bronchiolitis, lung cancer, and tuberculosis are the major chronic diseases associated with the pulmonary system. Knowledge about the affecting factors, namely, the etiology, pathophysiology, and the various barriers (mechanical, chemical, immunological, and behavioral) in pulmonary drug delivery is essential to develop an effective drug delivery system. Formulation strategies and mechanisms of particle deposition in the lungs also play an important role in designing a suitable delivery system.Areas covered: In the present paper, various drug delivery strategies, viz. nanoparticles, microparticles, liposomes, powders, and microemulsions have been discussed systematically, from a patent perspective.Expert opinion: Patent publications on formulation strategies have been instrumental in the evolution of new techniques and technologies for safe and effective treatment of pulmonary diseases. New delivery systems are required to be simple/reproducible/scalable/cost-effective scale for manufacturing ability and should be safe/effective/stable/controllable for meeting quality and regulatory compliance.
