Preparation and Evaluation of Herbal Cream Formulated from Calotropis gigantea Leaves
type: item
description: The present study aimed to formulate and evaluate a topical herbal cream using the leaf extract of Calotropis gigantea. Medicinal plants serve as an important source of bioactive compounds with significant therapeutic potential. Calotropis gigantea, widely used in traditional medicine, possesses antimicrobial, anti-inflammatory, and wound-healing properties. Fresh leaves were collected, authenticated, shade dried, pulverized, and subjected to Maceration extraction using propylene glycol. Preliminary phytochemical screening confirmed the presence of alkaloids, flavonoids, tannins, glycosides, saponins, and terpenoids. An oil-in-water (O/W) emulsion-based cream was formulated using suitable excipients. Four trial formulations (F1C–F4C) were prepared and evaluated for physicochemical properties including organoleptic characteristics, pH, spreadability, washability, phase separation, and skin irritation. The prepared formulations showed smooth texture, faint yellow color, pleasant odor, and semi-solid consistency. No irritation, erythema, edema, or phase separation was observed. Spreadability values indicated good applicability. The optimized formulation exhibited acceptable pH suitable for skin application. The study confirms the feasibility of developing a stable and safe herbal topical preparation using Calotropis gigantea leaf extract with potential therapeutic applications.

A Review on Ebola Virus Disease and Its Prevention and Management in Community
type: item
description: Ebola virus disease is a devastating hemorrhagic disease that is often fatal, has been plaguing Africa since its initial discovery in 1976. For more than 42 years, the disease has claimed the lives of over 15,000 people, with no significant changes in case fatality rates. However, as the global response to EVD evolves, we continue to learn about better ways to diagnose, treat and prevent this disease. EVD does not naturally occur in the human population; it is introduced after exposure to close contact with the secretions, meat or bodily fluids of animals, such as fruit bats, monkeys or other rainforest animals. The World Health Organization states that 2 negative RT-PCR test results, at least 48 hours apart, are required for a clinically asymptomatic patient to be discharged from hospital. Destruction of other tissue cells results in myalgias from myositis, hepatitis, and acute kidney injury from renal tubular dysfunction. Immune-mediated cell damage causes further injury, leading to dysfunction in multiple vital organs such as the lungs, heart, kidney, and liver. More healthcare programmes are required to conducting a large scale for developing the awareness about Ebola virus disease about preventive measures and eradication process. Extensive research investigations are needed to developed in an accurate diagnostic procedure as well as an affordable and rapid treatment initiatives can control Ebola virus infection.

Plant-Based Multifunctional Nutraceuticals as Preventive Interventions for Modern Lifestyle Disorders
type: item
description: In recent years, herbal formulations and nutraceuticals have gained wide acceptance due to their minimal adverse effects. Medicinal plants are known for their immune-enhancing properties, and nutrition during early childhood plays a crucial role in a child’s overall growth and development. Despite consuming a balanced diet, children often suffer from deficiency-related disorders. Owing to their close interaction with gut microbiota, nutraceuticals currently serve as an effective alternative for the prevention and management of dysfunctions associated with oxidative stress. Chronic non-communicable diseases such as cancer, diabetes, hormonal disorders including PCOS, cardiovascular diseases, neurodegenerative conditions, and autoimmune disorders are increasing worldwide, creating significant health and economic burdens. The primary objective of this study was to develop a multifunctional nutraceutical formulation using ingredients derived from various sources such as medicinal herbs, seeds, spices, and green leafy vegetables. The pharmacological efficacy of the formulation was evaluated through its mechanisms of action, including biotransformation processes and identification of relevant biomarkers. Since inflammation is one of the major contributing factors to disease progression, its reduction is essential, as it promotes the generation of free radicals and gut dysbiosis.

Investigation of Antidiabetic Activity and Antioxidant Activity of Moringa Oleifera in Rats
type: item
description: Plants have been used as source of drugs for the treatment of diabetes mellitus in developing countries where the cost of conventional medicines represents a burden to the population. Many species have been reported to present antidiabetic activity. Moringa oleifera is a plant traditionally used for the treatment of diabetes mellitus. This dissertation was designed based in the traditional claim to emphasize the antihyperglycemic, antioxidant potential of the ethanolic extract of Moringa oleifera. Preliminary phytochemical analysis of the EEMO extract of leaf of the plant showed that the plant has a rich possession of phytochemicals like flavonoids and steroids. In the sub-acute study, a steady decrease in blood glucose level was observed on EEMO treatment in Alloxan induced diabetic rats. The treatment of EEMO showed marked increase in body weight, marked increase in protein, HDL cholesterol levels in serum of Alloxan induced diabetic animals. EEMO has high scavenging activity against DPPH free radical generating system so it is considered to be a anti-oxidant. Based on the obtained results and observations, we can infer that the Moringa oleifera could be used for the supportive treatment of diabetes mellitus, as the plant also offers effective protection against free radicals that form the basis for the development of diabetic complications.

Therapeutic strategies on Blood brain barrier
type: item
description: BBB comprises different molecular components and transport systems, which in turn create efflux machinery or hindrance for the entry of several drugs in brain. It is a vital component of the neurovascular unit (NVU) containing tight junctional (TJ) proteins and different ion and nutrient transporters which maintain normal brain physiology. The blood-brain barrier (BBB) is responsible for much of this difficulty but also provides an essential separation from systemic circulation. Due to the BBB’s physical and chemical constraints, many current therapies, from cytotoxic drugs to antibody-based proteins, cannot gain access to the tumor. Various strategies are being developed to enhance the amount and concentration of therapeutic compounds in the brain. The present review describes those different approaches of therapeutic strategies on blood brain barrier. These approaches are mainly utilized to overcome the brain tumors.

Analytical Method Development and Validation for the Simultaneous Estimation of Gabapentin and Nortriptyline by RP-HPLC method
type: item
description: In RP-HPLC method, the conditions were optimized to obtain an adequate separation of eluted compounds. Initially, various mobile phase compositions were tried, to separate title ingredients. Mobile phase and flow rate selection was based on peak parameters (height, tailing, theoretical plates, capacity or symmetry factor), run time and resolution. The mobile phase containing mixture of Phophate buffer solution: Methanol (65:35v/v, pH 4) with a flow rate of 1.0 ml/min is quite robust. The optimum wavelength for detection was 260 nm at which better detector response for both the drugs was obtained. The retention times for Gabapentin and Nortriptyline was found to be 2.113 min and 3.560 min, respectively. To ascertain its effectiveness, system suitability tests were carried out on freshly prepared stock solutions. The calibration was linear in concentration range of 5 to 25μg/ ml and 20 to 100μg/ml, with regression 0.9979 and 0.9999, Gabapentin and Nortriptyline respectively. The low values of % R.S.D indicate the method is precise and accurate. The mean recoveries were found above 99.3 % for both the drugs.

A Review on Satellite DNA
type: item
description: Satellite DNAs are hidden part of the genomes, initially just considered as junk DNA. Heterochromatic regions of the eukaryotic genome harbour DNA sequences that are repeated many times in tandem, collectively known as satellite DNAs. Different satellite sequences co‐exist in the genome, thus forming a set called a satellite DNA library. Satellite DNA families accumulate in the in the heterochromatin in different parts of the eukaryotic chromosomes, mainly in pericentromeric and subtelomeric regions, there is currently an increasing appreciation of the functional significance of satellite DNA repeats and of their sequences. The study of insect satellite DNAs indicates the evolutionary conservation of certain features despite their sequence heterogeneity. Such features can include total length, monomer length, motifs, particular regions and/or secondary and tertiary structures.

Effect of Hydroalcoholic Extract of Orthosiphon Thymiflorus Leaves on Glycemia of Diabetic Rats
type: item
description: The present study was aimed to investigate the antihyperglcemic activity of hydroalcoholic extract of Orthosiphon thymiflorus leaves (HAEOT) on high fat diet (HFD) - streptozotocin (STZ) induced diabetic rats. Male wistar albino rats were fed with a high fat diet for a period of two weeks prior to the administration of streptozotocin (50mg/kg) intraperitonially. The long term effect of the extract was studied by treating diabetic rats with vehicle (0.5% CMC) and HAEOT (200 and 400 mg/kg b wt) for a period of 28 days. The effects of HAEOT on fasting blood glucose and serum insulin levels were studied. In addition, body weight changes, lipid profile and serum biomarkers of liver and kidney function were also studied. Results revealed that HAEOT-400mg shows excellent anti hyperglycemic activity when compared to lower dose of the extract 200mg and also shows better anti hyperlipidemic activity. The elevated serum urea and creatinine levels also decreased by the treatment with extract. Hence the results justify that Orthosiphon thymiflorus possess antidiabetic activity.

Formulation of Mucoadhesive Microspheres of Irbesartan and Their Evaluation
type: item
description: Mucoadhesive microspheres has been accepted as a process to achieve controlled drug delivery by prolonging the residence time of the dosage form at the site of absorption thereby improving and enhancing the bioavailability of drugs. Irbesartan is an Angiotensin receptor blocker (ARB) used mainly for the treatment of hypertension. It competes with Angiotensin II for binding at the AT1 receptor sub type. The mucoadhesive microspheres of Irbesartan were formulated by orifice ionic gelation technique employing polymers like Sodium Carboxy methyl cellulose and Carbopol along with Sodium alginate. The microspheres prepared were discrete, spherical and free flowing. Microspheres were evaluated for particle size, percentage yield, flow properties, drug content, and drug entrapment efficiency, percentage moisture loss, swelling property, in vitro drug release, drug release kinetics, in vitro wash-off test, stability study and drug polymer interaction study by FT-IR. The microencapsulation efficiency was found relatively high with 2% polymer. Average particle size was found in the range of 5.02±0.36 to 9.45±0.43μm. Formulations F6 displayed the best results for. Entrapment efficiency was 85.26±0.43%, swelling-index was 194±3.45% and drug release up to 8h was 94.97%. Drug release was diffusion controlled and followed first order kinetics. The in vitro wash-off test indicated that the microspheres had good mucoadhesive properties. Hence prepared mucoadhesive microspheres may be an effective strategy for the development of easy, reproducible and cost effective method for safe and effective oral drug therapy.

A Comparative Safety and Efficacy Study of Olmesrtan, a Newer Angiotensin-II Type-1 Receptor Blocker in Early Stage Type–2 Diabetes with Hypertension
type: item
description: Patients with type-2 diabetes are at high risk for developing cardiovascular diseases, which are also the most common cause of death in these patients. Angiotensin II type-1 receptor blockers (ARB) are widely used for the treatment of hypertension. Among the several ARBs available in the clinical setting, olmesartan is thought to have a significantly stronger blood pressure lowering effect than losartan or valsartan with their respective starting doses. In addition, recent data demonstrated that olmesartan more adequately achieved ambulatory blood pressure monitoring (ABPM) goals during the early morning surge period than did candesartan. Considering the importance of strict blood pressure control, olmesartan offers certain advantages in clinical use. With regard to its metabolic effect, telmisartan has the unique property of selective peroxisome proliferation–activated receptor (PPARγ) modulating activity, at least in-vitro. Thus, telmisartan might have clinical effects similar to those of PPARγ agonists, such as improving insulin resistance and increasing serum adiponectin levels. In fact, a recent study demonstrated that replacement of valsartan with telmisartan reduced serum highly sensitive C-reactive protein (hs-CRP) and increased serum adiponectin. Another study revealed that telmisartan has superior effects on metabolic parameters compared to losartan in hypertensive patients with metabolic syndrome. In addition, telmisartan blood pressure lowering effect is reported to last longer than valsartan’s. To gain insight into the respective properties of ARB for type-2 diabetic patients with hypertension, an open-label crossover trial was conducted to compare the efficacy of the starting doses of olmesartan and telmisartan on blood pressure, and metabolic parameters. A clinical study has shown that a doses in patients with type-2 diabetes, olmesartan seems to have more potent blood pressure lowering than telmisartan, but similar effects on metabolic parameters.

Evaluation of Cardioprotective Activity of Ethanolic Extract of Cordia sebestena Against Myocardial Infarction: A Comprehensive Review
type: item
description: Myocardial infarction (MI) remains one of the most prevalent and fatal cardiovascular disorders worldwide, primarily resulting from ischemia-induced oxidative stress, inflammation, and cardiomyocyte apoptosis. Although conventional pharmacotherapy has significantly reduced mortality, long-term usage is often associated with adverse effects, necessitating the exploration of safer cardioprotective agents. Medicinal plants rich in bioactive phytoconstituents have emerged as promising alternatives due to their multitarget therapeutic potential. Cordia sebestena L., belonging to the family Boraginaceae, is traditionally employed for the treatment of inflammatory and oxidative stress–related disorders. The ethanolic extract of Cordia sebestena is reported to contain flavonoids, phenolic compounds, tannins, saponins, and terpenoids, which possess potent antioxidant and anti-inflammatory properties. This review comprehensively evaluates the cardioprotective activity of the ethanolic extract of Cordia sebestena against myocardial infarction, focusing on its phytochemical profile, mechanistic pathways, experimental evidence, and future therapeutic prospects. The collective findings suggest that Cordia sebestena exhibits significant cardioprotective effects by attenuating oxidative stress, stabilizing myocardial membranes, modulating inflammatory mediators, and preventing cardiomyocyte apoptosis.

A Scientific Report on Immunosupression Used For Liver Transplantation
type: item
description: Continued advances in surgical techniques and immunosuppressive therapy have allowed liver transplantation to become an extremely successful treatment option for patients with end-stage liver disease. Beginning with the revolutionary discovery of cyclosporine in the 1970s, immunosuppressive regimens have evolved greatly and current statistics confirm one-year graft survival rates in excess of 80%. Advances in immune suppressants over the past decade have resulted in dramatic improvements in short- and long-term outcomes in organ transplantation as well as a decreased incidence of acute rejection. However, immunosuppressive drugs need to be given long term, lack specificity, and are accompanied by adverse metabolic derangements, toxicities, the risk of infection and cancer, and a myriad of other side effects.

Design, Development & Evaluation of Domperidone Dispersible Tablet
type: item
description: “The present study was aimed to prepare dispersible tablet of domperidone by using dried mucilage (DM, i.e. Mucilage isolated from seed of Ocimum basilicum) as novel disintegrant & to confirm the mechanism of disintegration of DM, ie. Mucilage isolated from seed of Ocimum basilicum”. There are several technologies that produce commercially available DTs. ZydisR (Cardinal Health, Dublin, Ohio), OraSolvR /Dura Solv R (Cima Labs, Eden Prairie, Minnesota) and WOWTABR (Yamanouchi Pharma Technologies, Norman, Oklahoma) are widely known technologies. Although these technologies meet the special requirements for DTs to some extent, none has all the desired properties. The technologies are usually grouped according to the method used in making DTs, such as freeze drying, molding, and compression. Compression is the most widely used method for making DTs. Some methods are focused on unique granulation methods, such as spray-drying and flash-heating, to make shear form formulations; some are focused on selecting specific excipients such as water-insoluble calcium salt, specific disintegrant combination, and specific sugar combination; and some are focused on special treatment after compression, such as sublimation, sintering, and humidity treatments. In-vitro release study showed 75-80 % drug release from formulations of factorial batches within five to ten min. Formulation F3 disintegrated rapidly as compared to other factorial batches and hence taken further for stability studies and was found stable at the end of stability testing conducted as per the ICH guidelines. The dissolution profile of optimized batch F3 was compared with the dissolution profile of marketed formulation. There was no significant difference in the profile when compared statistically by applying t test at p<.

Exploration of Autochthonous Fungal Population and its Bioactive compounds Elucidation from the Three Different Coconut Water Samples
type: item
description: Coconut (Cocos nucifera L.) water is a refreshing drink consumed mostly directly from the fruit. However, in recent times, consumers in Accra prefer to have it transferred into plastic bags for later consumption; this favours a high risk of bacterial contamination. Since it is rich in nutrient, it may become unwholesome with possible high bacteria loads. Tender coconut water is a refreshing drink with electrolytes (ionic mineral) similar to human plasma. This refreshing drink is filled with many healthy natural nutrients which can enhance the body's metabolism and immunity and is used more as a health supplement. Initially these three kinds of coconut water interestingly present various diversity of the fungal organisms with different morphological in nature. Mainly those organisms were predominantly developed on two experimental coconut water such as tender and mature coconut water except king coconut water. Though, totally nine numbers of mouldy appearance white colour fungi were seen on mature coc. water and this similar kind of fungi five number also present in tender coco. Water too. But this kind of observed fungi didn’t develop on the third water sample (King coco. water) Data not shown. Furthermore, other kind of morphologically different round shaped pale green colour fungi organisms also been noticed on both two samples (mature and tender coc. water) but it was absent in king water. In addition small thickened pure dark green colour fungi developed on the three coconut water samples viz., 11 in mature, 8 in tender and 5 in king coc. Water respectively. From the present result clearly showed among the three different kinds of coconut king coconut water showed maximized chemical as well as protein composition has been noticed than the control also other two varieties of coconut water. Although, exceptionally small white colour organisms were present. As a result of this coconut water imply that should it be contaminated shortly after two or three days of inc…

Integrated Analytical Quality by Design (AQBD) Approach for the Development and Validation of Liquid Chromatography Method for Simultaneous Estimation of Rimantadine
type: item
description: A simple, precise, and robust reverse-phase high-performance liquid chromatography (RP-HPLC) method was developed and validated for the estimation of Rimantadine in bulk and pharmaceutical dosage forms in accordance with ICH Q2(R1) guidelines. Method optimization confirmed that flow rate, buffer pH, and organic ratio significantly influenced chromatographic performance. The optimized method employed an Inspire C18 column (3.0 × 150 mm, 5 µm) with a mobile phase consisting of phosphate buffer (pH 3.0) and methanol, delivered at a flow rate of 1.0 mL/min, with detection at 265 nm. A sharp and symmetrical peak was obtained at a retention time of 6.12 min, with system suitability parameters meeting all acceptance limits (plate count >5800, tailing factor ~1.0).Validation studies demonstrated excellent linearity in the concentration range of 15–75 µg/mL (R²=0.9994), high precision with %RSD values below 0.2%, and accuracy with mean recoveries between 96.7–101.2%. The method was sensitive with LOD and LOQ values of 2.96 µg/mL and 9.97 µg/mL, respectively. Robustness testing confirmed that deliberate variations in flow rate and mobile phase composition did not significantly affect results. Overall, the developed RP-HPLC method is accurate, reproducible, cost-effective, and stability-indicating, making it highly suitable for routine quality control, batch release, and regulatory applications of Rimantadine formulations.

Formulation Development and Characterization of Posaconazole Loaded Nanoparticle Gel
type: item
description: The present study focused on the development and evaluation of Posaconazole-loaded nanostructured lipid carriers (NLCs) as a novel topical delivery system to overcome limitations of conventional formulations such as poor solubility, low bioavailability, and inadequate tissue retention. Posaconazole, a broad-spectrum triazole antifungal, was incorporated into solid lipid nanoparticles (SLNs) and NLCs using the melt emulsification ultrasonication method, with optimization carried out through a full factorial design (3³). Critical formulation factors including lipid-drug ratio, surfactant concentration, and sonication time significantly influenced particle size and entrapment efficiency. Optimized formulations demonstrated particle sizes ranging from 80–150 nm for NLCs with high entrapment efficiency (up to 85%) and stable zeta potential (–13 to –15 mV). Differential Scanning Calorimetry and Scanning Electron Microscopy confirmed successful drug encapsulation and uniform spherical nanoparticles, respectively. The optimized NLC was incorporated into an aloevera based carbopol gel, yielding a formulation with appropriate pH, viscosity, spreadability, and rheological characteristics suitable for topical application. In vitro permeation studies indicated enhanced skin retention of Posaconazole with minimal systemic penetration, while fluorescent microscopy confirmed deeper layer skin targeting. Antifungal evaluations demonstrated superior efficacy of the NLC gel against Candida albicans and Aspergillus fumigatus, with sustained activity, reduced fungal burden, and significant anti-inflammatory effects in in vivo models. Overall, the developed Posaconazole-loaded NLC gel showed promising potential as a safe and effective topical drug delivery system, combining enhanced local drug retention with improved therapeutic outcomes and reduced systemic side effects.
