2024-11-14T09:29:42+00:00

Background: 60–70% of cases of memory loss are caused by Alzheimer's disease (AD). It is a violent type of memory loss manifesting in memory, language and behavioural deficits. The primary risk of AD is advancing age. The incidence rates change with ages. After the age of 65 incidence rate of disease become double and differs in the sex also. Women are more proven for the disease particularly after the age of 85. The risk of dying from AD is higher in white non-Hispanics than in black non-Hispanics, although the Hispanic population is less likely to get AD than non-Hispanic whites. Whereas non-Hispanic whites have a higher risk of dying from AD than non-Hispanic blacks, the Hispanic population is less likely to get AD.

This study was undertaken in order to evaluate learning and memory impairment activity of the methanolic extract of Albizia procera R. (MEtAP) leaves in animal models. Albizia procera R. (AP) is a fast-growing subtropical and tropical tree belonging to the Fabaceae family's Mimosoideae subfamily. AP is a herb widely used in the Asian traditional medicine as antioxidant, analgesic, antibacterial¸ antidiarrheal and antidiabetic drug. AD is a chronic neurological disease.

Methods: The leaves of AP were collected, authenticated, dried and extracted with methanol. The effect of the MEtAP leaves (200 and 400 mg/kg, taken orally once a day for 28 days)

on learning and memory performance was assessed using Modified EPM apparatus and MWM apparatus. Learning and Memory impairment was induced by chronic restraint stress.

Results: In Modified EPM apparatus the treated rats exhibited decrease entries and time spent in the closed arm and increase entries and time spent in open arm. In MWM Apparatus the treated rats exhibited increase in the retention time and decrease in the escape latency. In calorimetric analysis the level of acetylcholinesterase decreases by the plant extract to some extent and helps in the learning and memory enhancement. Administration of MEtAP leaves significantly improved those parameters suggesting positive effects on learning and memory impairment activity.

Conclusion: The present finding indicates that the MEtAP leaves exhibits significant mild to moderate learning and memory enhancement activity at low dose (200 mg/kg) and high dose (400 mg/kg) Thus, AP is a promising herbal option in the pharmaceutical world.

2024-12-02T13:24:28+00:00

Scientists and the food business are currently interested in a vast range of microbes called lactic acid bacteria (LAB) and yeasts. Despite playing a significant role in the taste improvement of fermented foods, their antimicrobial qualities haverecently come to light. Standard techniques were used in this investigation to describe the LAB and yeasts derived fromthe fermented milk primarily on their morphological, microscopic, and biochemical characteristics. Furthermore,antilisterial activities of lactic acid bacteria and yeasts were performed. Also, the antilisterial activities of neutralized LABand yeasts and the effect of treatment of pH, NaCl, and enzyme activities against Listeria monocytogenes were performed. Lastly, a co-culture of LAB and yeast with Listeria monocytogenes in skimmed milk was done. Twenty lactic acid bacteriaisolates obtained from fermented cow milk were characterised as Lactobacillus rhamnosus, Lactobacillus plantarum,Lactobacillus delbrueckii, Lactobacillus brevis, Lactobacillus casei, Lactobacillus fermentum, and Lactococcus lactis while twenty- five yeast isolates obtained from fermented cow milk were identified as Saccharomyces cerevisiae,Debaryomyces hansenii, Pichia anomala, Kluyveromyces lactis, Trichosporon mucoides, Saccharomyces barnettii and Saccharomyces bayanus with different frequency. The secretion of metabolites like organic acids, hydrogen peroxide,diacetyl, and bacteriocin by lactic acid bacteria led to the inhibition of Listeria monocytogenes, whereas the synthesis oforganic and volatile acids, substantial quantities of ethanol, hydrogen peroxide, while mycocins by yeasts led to theirinhibition. When treated with -amylase and at pH 4–7, bacteriocins and mycocins remained constant, but part of their activity was reduced when treated with protease. As pH and NaCl concentration increased, the activity of bacteriocins and mycocins decreased. In the presence of the LAB and yeasts, Listeria monocytogenes showed a delay in growth and lowmicrobial count for the control during the co-culturing experiment.

Can Microorganisms Produce Biobutanol after Agricultural Wastes Pretreatment?

2024-12-02T13:28:10+00:00

This review investigates the possibility of biobutanol as a renewable energy source for addressing the environmental issues associated with traditional carbon-based fuels. As energy demand rises, carbon emissions from fossil fuels exacerbate climate change, emphasizing the importance of sustainable, low-emission alternatives. Bioenergy, which is produced from organic waste via biochemical processes, is a possible replacement. Biobutanol, in particular, has an advantage over bioethanol due to its cleaner combustion and applicability for a variety of applications; nevertheless, the toxicity of biobutanol to its producing bacteria reduces production efficiency. Gas stripping recovery systems are presented as solutions for increasing output.

Renewable energy is classified into four types based on its source: edible crops, non-edible biomass (such as lignocellulose), cellular materials, and carbon capture. Currently, first-type renewables dominate, but agricultural concerns are moving the focus to non-food sources. Second-generation renewables, particularly lignocellulose, offer considerable benefits by exploiting whole plant biomass with minimum land needs. Biobutanol, a second-type renewable, is recognized for its ability to satisfy energy demands while promoting environmentally good activities. This analysis emphasizes biobutanol's potential for bioenergy, notably from agricultural waste, and advocates for more research into production upgrades.

(Moringaceae) is a bush of African savannah, commonly known as Drum stick used in folk Medicine for the treatment of rheumatic and articulanry pain. Its seeds shown analgesic activity [7], Antipyretic activity [8]. Analgesic and anti-inflammatory effects of flavonoids, steroids and tannins have been reported [23] hence the analgesic and anti-inflammatory effects produced by these extracts may be attributed due to the flavonoids and steroids. However, its pharmacological actions and mechanisms have not been precisely documented in spite of its increasing usage recently. Present work reported the potential effects of the stem bark of Moringa oleifera, as an anti-inflammatory agent using both in vivo and in vitro models. Carrageenan-induced paw edema and cotton pellet granuloma formation in rats reflect the edematous stages during acute and chronic inflammation. [24,25] In the present study, two different extracts of leaves of Moringa oleifera were tested. Carrageenan induced rat paw edema has been a popular inflammatory model to investigate nonsteroidal anti-inflammatory effect of compounds [26] Serotonin, histamine, bradykinin, and prostaglandin have been identified as a mediators for carrageenan induced rat paw edema. [27] Petroleum ether and methanolic extracts were found to possess a prominent anti-inflammatory activity, showing inhibition to the paw edema induced by carrageenan during the three time points from 1 to 3 h. In cotton pellet granuloma model Petroleum ether and methanolic extracts showed significant inhibition.

Pharmacovigilance of Herbal Drugs (Herbovigilance)

2024-12-12T16:12:57+00:00

Improved traditional medicine/phytomedicine formulations have gained a global acceptability and popularity as therapeutic agents for many diseases in Sub-Saharan Africa. Herbal products are generally considered as safe, environmentally friendly and increasingly consumed by the community without a prescription. There is a lack of systematic data on traditional medicine- associated adverse effects due to complex issues such as products with multiple ingredients, poor standardization, lack of clinical trials, variation in manufacturing processes, contamination, adulteration and misidentification of herbs. The aim of pharmacovigilance is to detect, assess, understand, and prevent the adverse effects or any other possible drug-related problems, related to herbal, traditional and complementary medicines. Pharmacovigilance for herbal medicines is in its infancy, and monitoring the safety of natural products presents unique challenges, and as such, preparations are available from a wide range of sources where limited qualified healthcare professionals are available. The ethico-legal issues and regulatory approval mechanism of herbal medicine vary from country to country. This paper also elucidates the level of challenges associated with herbal pharmacovigilance geared towards improving safety monitoring for herbal medicines in the future. The importance of herbal remedies in pharmacovigilance systems is becoming one of the primary tasks, due to the constantly ascending potential of herbal products and herbal medicines worldwide. Nowadays, the drug development is focused on finding new active compounds or combinations, but costs are simultaneously growing, which makes herbal medicines an attractive, harmless and cheaper alternative to synthetic drugs.

Like all drugs, herbal are not free of risk and many studies suggest for potential adverse reactions and interactions. Available statistics show that some herbal products, used in traditional medication for generations, may possess carcinogenic, hepatotoxic, cardiotoxic and other severe actions. Evaluation of the safety should include at least in vitro and in vivo genotoxicity assays, long-term rodent carcinogenicity tests (for drugs intended to be continuously used for >3 months or intermittently for >6 months), reproductive and developmental toxicity studies in some cases and examination of the effects on drug-metabolizing enzymes.

Drug safety of herbal medicines should be developed, focusing on specific groups of patients. Herbal formulations being widely accepted therapeutic agents as antidiabetics, antiarthritics, hepatoprotectives, cough remedies, memory enhancers, and adaptogens. The commonest myth regarding herbal medicines is that these medicines are completely safe, and can therefore be safely consumed by the patient on his/her own, without a physician's prescription. This belief has led to large-scale self-medication by people all over the world, often leading to disappointing end-results, side-effects, or unwanted after-effects. There is an increasing awareness at several levels of the need.

To Explore Cu-Catalyzed Oxidative Amidation of Cinnamic Acids / Arylacetic Acids with 2-Amines

2024-12-18T05:44:52+00:00

When it comes to pharmaceutical components in particular, air-and moisture-sensitive organometallic species might be problematic due to their inherent contamination, functional group compatibility issues, and stringent reaction conditions. The method's synthetic value was further shown by conducting a gram scale reaction under standard circumstances using cinnamic acid and morpholine. This reaction yielded the intended product, 1-morpholino-2-phenylethane-1,2-dione (3a), in 51% yield. The reaction's viability was assessed by meticulously manipulating a model reaction involving isatin and (E)-3-(benzylamino)-3-(methylthio)-1-phenylprop-2-en-1-one, changing variables including catalyst, solvent, temperature, and molar concentration of the reactants. The results of the control tests, the products' isolation, and the current literature are used to construct a plausible mechanism.

To Design QBD (Quality-by-Design) Approach to Understand the Processing Factors Impact Melt-Extruded Solid Dispersions with an Instantaneous Release

2024-12-18T15:43:57+00:00

Quality by Design (QbD) is a method for determining which patient-reported quality factors are most important, translating those factors into product attributes, and then determining how to consistently produce drug products with those attributes by varying key process parameters. For this purpose, it is necessary to identify sources of variability and create correlations between product features and factors pertaining to the formulation and manufacturing process, such as the properties of the medication ingredient and excipients, as well as process parameters. Using this information, a strong and adaptable manufacturing process is put into place, allowing it to consistently create high-quality products over time. Although hot-melt extrusion (HME) has been around for a while in the food and plastics industries, it wasn't until 1971 when El-Egakey et al. used it to pharmaceutical formulation. Different research organizations dug further into this method, honing it for use in the pharmaceutical industry.

The Interactions between Heterocyclic Compounds and Target Proteins Involved with Cancer

2024-12-19T16:29:09+00:00

Worldwide, cancer ranks as the second most lethal disease. The World Health Organisation predicts that by 2030, there will be 22 million new instances of cancer worldwide. Cancer prevention, diagnostic, and treatment procedures are the subject of extensive global research. The metabolic profile of cancer cells differs from that of normal cells due to epigenetic and genetic abnormalities. Many anti-cancer medications on the market include heterocycles as their primary structural component. Additionally, anticancer medications that were authorised by the FDA between 2010 and 2015 have heterocyclic rings in their structural makeup. Their massive cellular processes and mechanisms, together with their abundance in nature, explain why they are present in anti-cancer medications. This study sheds light on several heterocyclic compounds that have anticancer effect on various cell lines. These compounds have rings that contain nitrogen, sulphur, and oxygen. Collecting information on heterocyclic rings can pave the path for the discovery of novel compounds with cancer-fighting potential in the future.
