Phytochemical analysis and anti-emetic activity of illicium verum hook. f. fruit by chick emesis model

Emesis is defined as a forceful expulsion of stomach contents via the mouth. The adverse effects of available anti-emetic drugs potentiate us to evaluate natural products to explore effective natural anti-emetics with fewer side effects. The fruits of Illicium verum Hook. f. were selected for anti-emetic activity based on their folkloric use against gastrointestinal complaints. Crude methanolic extract and its aqueous, dichloromethane, ethylacetate and hexane fractions were evaluated using the copper sulphate-induced chick emesis model. Emesis was induced by the oral administration of copper sulfate 10 ml/kg body weight and metoclopramide (150 mg/kg p.o.) as a standard anti-emetic drug. The anti-emetic effect was observed by calculating the mean decrease in the number of retches compared to that of the control. Methanolic extract and its fractions were tested at 25, 50 and 75 mg/kg oral doses. Among all tested fractions, ethyl acetate showed the highest (94.46%), and hexane showed the lowest (56.30%) anti-emetic activity at 50 mg/kg. Further, isolation and purification from the same fractions are in process to discover effective natural anti-emetic compound(s) with less unwanted effects.

Symmetric key cryptosystem based on randomized block cipher

Multimedia data encryption attempts to prevent unauthorized disclosure of confidential multimedia information in transit or storage. Security of multimedia files attracts more and more attention and many encryption methods have been proposed in literature. If we call a multimedia data stream (message) plaintext , the process of transforming the plaintext into unintelligible data stream is referred to as multimedia encryption (MME) where the encrypted message (data stream) is often named ciphertext. The process of transforming the ciphertext back into plaintext is termed decryption. We propose a new block cipher based on randomized key of size n × n where n is the block size and the block undergoes n 2 iterations with the plaintext. Every iteration generates the pseudo cipher text. The encryption process generate the ciphertext C with the help of the randomized key. The decryption apply the key in reverse order on the cipher text, to get back the plain text. This work deals with the problem of efficient multimedia data encryption.

An international, interlaboratory ring trial confirms the feasibility of an extraction-less “direct” rt-qpcr method for reliable detection of sars-cov-2 rna in clinical samples

Reverse transcription–quantitative polymerase chain reaction (RT-qPCR) is used worldwide to test and trace the spread of severe acute respiratory syndrome coronavirus 2 (SARSCoV-2). “Extraction-less” or “direct” real time–reverse transcription polymerase chain reaction (RT-PCR) is a transparent and accessible qualitative method for SARS-CoV-2 detection from nasopharyngeal or oral pharyngeal samples with the potential to generate actionable data more quickly, at a lower cost, and with fewer experimental resources than full RT-qPCR. This study engaged 10 global testing sites, including laboratories currently experiencing testing limitations due to reagent or equipment shortages, in an international interlaboratory ring trial. Participating laboratories were provided a common protocol, common reagents, aliquots of identical pooled clinical samples, and purified nucleic acids and used their existing in-house equipment. We observed 100% concordance across laboratories in the correct identification of all positive and negative samples, with highly similar cycle threshold values. The test also performed well when applied to locally collected patient nasopharyngeal samples, provided the viral transport media did not contain charcoal or guanidine, both of which appeared to potently inhibit the RT-PCR reaction. Our results suggest that direct RT-PCR assay methods can be clearly translated across sites utilizing readily available equipment and expertise and are thus a feasible option for more efficient COVID-19 coronavirus disease testing as demanded by the continuing pandemic.

New dimension in higher education in india

Higher Education has an important role in the task of rebuilding a nation and it pavCes the way for overall development of a nation. The twentieth century has witnessed several revolutions like Green revolution, White revolution, I.T revolution, so on and so forth, taking human civilization to new heights. At the start of 21st century, we gave a lot of importance given to higher education. Every country realized the value of higher education and the benefits that accrue from it. “The social demands for higher education continue to increase. The inabilities of the state to support this growing demand result in new financing arrangements for higher education. The recent reforms in this area could be broadly divided into two categories: the privatization of public institutions and the establishment of private institutions of higher education. Privatization implies the application of market principles in the operation of public institutions, while ownership rests within the public domain. Promotion of the private sector implies the growth and expansion of the non-state sector in higher education, and very often this sector does not rely on state funding for its growth and expansion. Both of these measures have paved the way for market operations in higher education

Exploring performance parameters of artificial allosteric protein switches

Biological information processing networks rely on allosteric protein switches that dynamically interconvert biological signals. Construction of their artificial analogues is a central goal of synthetic biology and bioengineering. Receptor domain insertion is one of the leading methods for constructing chimeric protein switches. Here we present an in vitro expression-based platform for the analysis of chimeric protein libraries for which traditional cell survival or cytometric high throughput assays are not applicable. We utilise this platform to screen a focused library of chimeras between PQQ-glucose dehydrogenase and calmodulin. Using this approach, we identified 50 chimeras (approximately 23% of the library) that were activated by calmodulin-binding peptides. We analysed performance parameters of the active chimeras and demonstrated that their dynamic range and response times are anticorrelated, pointing to the existence of an inherent thermodynamic trade-off. We show that the structure of the ligand peptide affects both the response and activation kinetics of the biosensors suggesting that the structure of a ligand:receptor complex can influence the chimera's activation pathway. In order to understand the extent of structural changes in the reporter protein induced by the receptor domains, we have analysed one of the chimeric molecules by CD spectroscopy and hydrogen-deuterium exchange mass spectrometry. We concluded that subtle ligand-induced changes in the receptor domain propagated into the GDH domain and affected residues important for substrate and cofactor binding. Finally, we used one of the identified chimeras to construct a two-component rapamycin biosensor and demonstrated that core switch optimisation translated into improved biosensor performance.

A natural language processing approach to determine the polarity and subjectivity of iphone 12 twitter feeds using textblob

Sentiment analysis and opinion mining is a branch of computer science that has gained considerable growth over the last decade. This branch of computer science deals with determining the emotions, opinions, feelings amongst others of a person on a particular topic. Social media has become an outlet for people to voice out their thoughts and opinions publicly about various topics of discussion making it a great domain to apply sentiment analysis and opinion mining. Sentiment analysis and opinion mining employ Natural Language Processing (NLP) in order to fairly obtain the mood of a person’s opinion about any specific topic or product in the case of an ecommerce domain. It is a process involving automatic feature extractions by mode of notions of a person about service and it functions on a series of different expressions for a given topic based on some predefined features stored in a database of facts. In an ecommerce system, the process of analyzing the opinions of customers about products is vital for business growth and customer satisfaction. This proposed research will attempt to implement a model for sentiment analysis and opinion mining on Twitter feeds. In this paper, we address the issues of combining sentiment classification and the domain constraint analysis techniques for extracting opinions of the public from social media. The dataset that was employed in the paper was gotten from Twitter through the tweepy API. The TextBlob library was used for the analysis of the tweets to determine their sentiments. The result shows that more tweets were having a positive subjectivity and polarity on the subject matter.

Use of weight-reducing products among libyans: pharmacist intervention in obesity management

Obesity is a complex and challenging global public health concern. It is a major disease involving excessive fat accumulation that may impair health. Obesity is dangerous and has been related to a range of long-term health issues that can impact adults and children. According to the World Health Organization, more than one billion people worldwide are obese as of March 2022. In the Libyan situation, the prevalence of obesity has increased among the public over the last decade. This cross-sectional survey-based study is conducted by using self-structured designed questionnaire to evaluate the use of anti-obesity drugs and herbal products among Libyan people. Additionally, considered as an indirect method, pharmacist performance in obesity management was also evaluated. The investigators collected interview data from three different cities in the Northwest of Libya over a period of five months, 2019. A total of 170 participants who use weight loss products were randomly selected to participate in the study after obtaining their verbal consent. The participants' experience with weight reduction agents revealed that more than half of the participants (52.3%) used herbal products while 32.0% of the participants have used drugs of chemical origin and 15.6% have used both (herbal and drugs). The majority of the participants (91.4%) used these products without medical consultation which in turn led to failure to lose and maintain weight with 74.2% gaining weight after stopping using these products. In conclusion, poor pharmacist intervention in obesity management was revealed where the majority of the participants reported that Libyan community pharmacists had not been offering weight management services, monitoring weight loss progress, or explaining the risks of being overweight or obese.

Synthesis and toxicity of graphene oxide nanoparticles: a literature review of in vitro and in vivo studies

Nanomaterials have been widely used in many fields in the last decades, including electronics, biomedicine, cosmetics, food processing, buildings, and aeronautics. The application of these nanomaterials in the medical field could improve diagnosis, treatment, and prevention techniques. Graphene oxide (GO), an oxidized derivative of graphene, is currently used in biotechnology and medicine for cancer treatment, drug delivery, and cellular imaging. Also, GO is characterized by various physicochemical properties, including nanoscale size, high surface area, and electrical charge. However, the toxic effect of GO on living cells and organs is a limiting factor that limits its use in the medical field. Recently, numerous studies have evaluated the biocompatibility and toxicity of GO in vivo and in vitro. In general, the severity of this nanomaterial’s toxic effects varies according to the administration route, the dose to be administered, the method of GO synthesis, and its physicochemical properties. This review brings together studies on the method of synthesis and structure of GO, characterization techniques, and physicochemical properties. Also, we rely on the toxicity of GO in cellular models and biological systems. Moreover, we mention the general mechanism of its toxicity.

Marine peptides in lymphoma: surgery at molecular level for therapeutic understanding

Lymphoma, the most common form of blood cancer, affects primarily the intricate network of tissues and organs known as the lymphatic system. Globally, it ranks among the leading causes of cancer-related deaths. Although conventional therapies have led to significant advancements, they are accompanied by adverse side effects and present challenges in cases of multidrug resistance, refractory patients, and relapses. This highlights a pressing need for innovative treatment approaches. Extensive research on the anti-lymphoma properties of natural compounds has particularly focused on marine organisms as valuable sources for potential medicinal agents. Among these, anticancer peptides have garnered attention due to their multiple beneficial effects against cancer, coupled with reduced toxicity to normal cells. This review focuses on the molecular mechanisms underlying the anti-lymphoma effects of marine peptides, examining the diverse pathways through which these peptides impact physiological processes. Key effects include modulation of cell viability, induction of apoptosis, cell cycle arrest, antimitotic activity, immunotherapeutic properties, disruption of mitochondrial function and induction of oxidative stress, cancer cell membrane destruction, and interference with microtubule stability. The review also highlights the antibody–drug conjugates (ADCs) derived from marine peptides and their synergistic effects with other anti-lymphoma medications. This knowledge should inspire future study and development of these prospective therapeutic modalities and hasten the investigation and creation of novel lymphoma remedies derived from marine sources.

Covid-19 in yemen: the present situation and the future plan to overcome the crisis

Since the WHO declared COVID-19 a pandemic on March 11, 2020, all countries worldwide have taken precautions to combat this pandemic, except for Yemen. The civil war and resulting humanitarian crises have diverted the attention of the Yemeni people and authorities away from COVID-19, potentially leading to the escalation of the pandemic. Following the initial denial, the internationally recognized government and the de facto authority of the Houthis acknowledged the first COVID-19 cases on March 11, 2020 and May 13, 2020, respectively. With only half of the Yemeni hospitals and medical facilities being fully operational, the authorities and humanitarian groups are working together to end the crisis. Due to paucity of information on the real number of cases in the country attributed to various reasons, no one can predict the future in this country, which will be most likely worse unless the civil war stops, and the humanitarian groups with the authorities need to work hard to strengthen the health system to prepare it for the current and all upcoming health crisis and pandemics.
