This study aims to examine the ethnobotanical uses, phytochemical composition, toxicity, and central nervous system activities of UA. It promotes learning and memory and has biological effects against Alzheimer's disease, Parkinson's disease, and cognitive impairment, according to pharmacological investigations. UA did not cause any death, abnormal body weight, or pathological diseases at any of the test doses. Furthermore, no behavioral, neurotoxin, coagulation, haematological, or clinical chemistry changes were seen as a result of UA treatment. UA is also used as a cosmeceutical product to improve skin functions. This article examines all knowledge that has become available at this time for revealing the chemistry of the current has been extensively investigated based on the data, resulting in UA derivatives with improved potency, bioavailability, and stability being used to treat a number of non-communicable diseases. The pharmacological activity of UA has been exploited to improve learning and memory and treat depression, emotional stress, fatigue, anxiety, insomnia, Alzheimer’s disease, Parkinson’s disease, epilepsy, and schizophrenia. The effects of UA on the central nervous system detailed in this review. The majority of UA studies have been preclinical evaluations of cellular mechanisms in the central nervous system, and more translational clinical research is needed to assess the drug's safety and efficacy, as well as its favorable, biodistribution, which could be targeted using different pathways and administration routes. Several in vitro and in vivo studies have investigated the pharmacological properties of UA reporting neuroprotective effects and improvements in cognitive function. These effects are attributed to its antioxidant, antiapoptotic, and anti-inflammatory actions.

Cardiometabolic diseases (CMDs) continue to be the leading cause of mortality in both developed and developing nations, accounting for over 32% of all fatalities globally each year. Furthermore, dyslipidemia, angina, arrhythmia, heart failure, myocardial infarction (MI), and diabetes mellitus are the major causes of death, accounting for an estimated 19 million deaths in 2012. CVDs will kill more than 23 million individuals each year by 2030. Nonetheless, new drug development (NDD) in CMDs has been increasingly difficult in recent decades due to increased costs and a lower success rate. Drug repositioning in CMDs looks promising in this scenario for launching current medicines for new therapeutic indications. Repositioning is an ancient method that dates back to th...

A common macroscopic complication associated with diabetes is cardiomyopathy. Cardiomyopathy refers to diseases of the heart muscle, where the heart muscle becomes enlarged, thick, or rigid. As cardiomyopathy worsens, the heart becomes weaker and is unable to conduct the right amount of blood through the body and maintain a normal electrical rhythm. This can lead to heart failure or arrhythmias. Chronic diabetes is one of the instigating factors behind the etiology of this cardiac complication. Type-II diabetes is associated with impaired glucose metabolism that increases the dependence of a diabetic heart on fatty acid oxidation to meet its functional demands, resulting in mitochondrial uncoupling, glucotoxicity, lipotoxicity and initially subclinical cardiac dysfunction that finally gives way to heart failure. The increasing diabetic population with cardiac di...

Memory storage is the process that demands the movement of signals, neural plasticity, and the molecules which can transfer the signals from the sensory neuron to the dorsal root ganglion (DRG) neurons and later into the temporal region of the brain. The discovery of cAMP in 1958 as the second messenger also had a role in memory formation and other neural aspects. Further, in 1998 the scientists found that cAMP does not just activate protein kinase A (PKA) but also exchange protein directly activated by cAMP (Epac) which has an active role to play in hyperalgesia, memory, and signaling. The cAMP has three targets, hyperpolarization-activated cyclic nucleotide modulated (HCN) channels, protein kinase A (PKA), and exchange protein activated by cAMP (Epac). Different research has exposed that both PKA and HCN channels are significant for lo...

DFUs are displayed as open sores or wounds located on the bottom of the foot as a secondary complication of diabetes mellitus (DM). DFUs are associated with significant morbidity and mortality and can subsequently lead to hospitalization and lower limb amputation if not recognized and treated on time. An immense challenge to conventional treatments is caused by the chronic nature of diabetic foot syndrome and it has led to the emergence of nanotechnology-based therapeutics. The greatest advantages of these nanotherapeutics are their unique biological, chemical, and physical properties. The present review highlights the augmentation of bacterial infections relating to delayed healing of DFUs and the potential of nanotherapeutics such as polymeric nanoparticles, metallic nanoparticles, siRNA-based nanoparticles, lipid nanoparticles, and nanofibers in accelerating wound healing in diabetic ...

The centre of consideration for this study is to provide solubility enhancement, improved bioavailability and provide a better patient compliance. To improve the hydrophilic and drug delivery characteristics, developed a beta-cyclodextrin and polyvinyl pyrrolidone K30 mediated fixed dose combination drug delivery system via solid dispersion technique. Inclusion complex was prepared as a fixed dose combination of these three bioactive phytoconstituent, obtained from natural sources with different polymers. The formations of inclusion complexes were characterized by Fourier transform infrared, drug content and drug dissolution. Saturation solubility studies also indicated that inclusion complex showed markable increased solubility compared toothers. Physical analysis of solid dispersion, when compared to its apparent compounds by FTIR allows for a change in solid state from the pure crystalline phase to the high-amorphous phase. The drug solubility increased in proportion to the increase in the concentration of polymer. The inclusion complex of PHC--CD prepared by solvent evaporation method demonstrated higher drug dissolution rates in comparison to solid dispersion prepared by solvent change precipitation method.

This risk may increase due to the opening of mitochondrial permeability transition pore (mPTP). The mPTP is also regulated by ischemic preconditioning (IPC) and a membrane protein known as caveolin. The cardioprotective effect of IPC is the most effective methodologies used in testosterone deficiency. Daidzein (DDZ) a caveolin inhibitor shows cardioprotective action. The experiment has been designed to evaluate the pretreated DDZ effect in IPC-mediated cardioprotective action in orchidectomy (OCZ)-challenged rat heart. The experiment was designed on male Wistar rats with/without OCZ. The level of testosterone is decreased by OCZ which reduces general body growth. Isolated heart from normal and OCZ rat was tied up on Langendorff's perfused apparatus and followed by ischemic reperfusion (IR) and IPC cycle. To investigate the cardioprotective effect of DDZ in heart with testosterone deficiency, a total of nine groups, each consisting of six rats (n = 6) were as follows: Sham, IR, IPC, IPC + OCZ, IPC + DDZ, IPC + OCZ + DDZ, IPC + sodium nitrite, IPC + OCZ + sodium nitrite, IPC + OCZ + DDZ + sodium nitrite. Hemodynamic parameters, cellular injury (infarct size, LDH, CKMB and cardiac troponin-T), oxidative stress, mitochondrial function, integrity and immunoblot analysis were assessed for each group. The experimental data showed that DDZ potentiated IPC-mediated increase in the heart rate, left ventricular diastolic pressure, coronary flow; + dp/dtmax, and - dp/dtmax. The pretreated DDZ decreases the action of LDH and CKMB, myocyte size, cardiac collagen content, infarct size and ventricular fibrillation and attenuation in oxidative stress and mitochondrial dysfunction in OCZ-challenged rat heart in all sets of experiments. Sodium nitrite, a producer of nitric oxide (NO), enhanced potentiating effects of DDZ on IPC-mediated cardioprotection in OCZ-challenged rats. These observations show that the downregulation of caveolin through impaired opening of mPTP during reperfusion and caveolin might be a potential adjuvant to IPC against cardiac injury in OCZ-challenged rats.

The current magnitude of the problem and the speed with which new resistance phenotypes are emerging elevates the public health significance of this issue. In recent decades, almost every variant of bacteria has become stronger and less vulnerable to antibiotic treatment, threatening new strains of infectious disease or super strains that are both more expensive to treat and more difficult to cure. A postantibiotic era, in which common infections and minor injuries can kill, far from being an apocalyptic fantasy, is instead a very real possibility for the 21st century. Antibiotic resistance has cast a shadow over the medical miracles we take for granted, undermining every clinical and public health program designed to contain infectious diseases worldwide. Limited access to medical care an...

Infract size, coronary flow, LDH, CKMB and histopathology were estimated. Sham control group decreased the LDH, CKMB and infract size in normal rat heart. The IPC mediated protection of heart was attenuated in OVX rat heart. Inhibition of GSK-3β is found to enhance the threshold of mPTP opening during reperfusion. The treatment with atractyloside stuck significantly the protection of heart of IPC in normal and OVX rat heart. These observations show that downregulation of GSK-3β through an impaired opening of mPTP during reperfusion and GSK-...

The core metabolic defects that mark diabetes, including impaired glucose tolerance, insulin resistance and proinflammatory state leading to endothelial dysfunction forms the pathogenesis of diabetic cardiomyopathy. Hyperglycemia triggers series of maladaptive stimuli that result in myocardial fibrosis and collagen deposition. Hyperglycemia induced mitochondrial reactive oxygen species (ROS) is also a significant contributor. Moreover, increases in sympathetic tone with diabetes are associated with changes in cardiac and vascular functions. ANS is responsible for modulating the activity of the sinus node (heart rate), ventricular (end systolic and diastolic volume) and blood vessels (systemic vascular resistance) and the dysfunction of the ANS may contribute to the development of arterial stiffness, left ventricular hypertrophy and ventricular diastolic dysfunction and cardiac autonomic neu...

It is a prevalent traditional herbal medicine that is chewed to separate collected fluid in the alimentary canal and for killing worms. Areca catechu seed contains alkaloids (arecoline, arecaine, arecaidine, guvacoline, guvacine, and choline), tannin, gallic acid, gum, and various minerals such as copper, calcium, phosphorus, and iron. The chemical constituents of this plant have been used as antidiabetic, stomatitis, bleeding gums, gingivitis, conjunctivitis, glaucoma, leucorrhoea, urinary disorders, anorexia, diarrhea, blood pressure regulating activity, antiulcerogenic, antioxidant activity, anticonvulsant activity, central nervous system stimulant activity, antifertility, oxytocic activity, antiviral activity, anthelmintic, and foul breath. It showed a dose-dependent toxicity profile, and various research has been done regarding its safety analysis and it would be considered safe when administered in the prescribed dose. The purpose of the present paper is to make available an up-to-date review on the ethnic, traditional description, morphology, phytochemistry, and the pharmacological and toxicological profile of this plant. Furthermore, the possible advances, trends, and a perspective for forthcoming research of this plant have also conversed.

The virus emerged in bats and was disseminated to humans in December 2019 via still unknown intermediate species in Wuhan, China. It is disseminated by inhalation or breaks out with infected droplets and the incubation period is between 2 and 14 days. The symptoms usually include high body temperature, cough, sore throat, dyspnea, low energy or tiredness, and weakness. The condition is moderate in most people; but in the elderly and those with comorbidities, it advances to pneumonia, acute respiratory distress syndrome (ARDS), and multiple organ failure. Popular research work includes normal/low WBC with upraised C-reactive protein (CRP). Treatment is generally supportive and requires home seclusion of suspected persons and rigorous infection control methods at hospitals. The Covid-19 has lower fatality than SARS and MERS. Among the proposed ...

The safety assessment of each of them is already established but no toxicological assessment has been done that would guarantee the safe use of these three flavonoids when used as a polyherbal combination (PHC). The aim of this study to evaluate the possible toxicological effect of polyherbal combination of these three flavonoids in female Swiss albino mice. Methods In acute toxicity study, the oral dose of poly herbal combination was administered to four groups stepwise in single dose and general behaviour, adverse effects and mortality were determined up to 14 days and compared to normal group. In sub-acute study, the tested poly herbal combination was administered orally for 28 days to the four experimental groups and their body weight was measured each alternate day from the first day of dosing. On 29th day the final body weight was re...

Animal models are required to propel our understanding of the pathogenesis, increase our knowledge, disease progress, and mechanism behind cardiovascular disorder, providing new approaches focused to improve the diagnostic and the treatment of these pathological conditions and additionally to test various therapeutic ways to deal with tissue regeneration and re-establish heart working following damage. A perfect model framework ought to be reasonable, effectively controlled, reproducible, and physiologically illustrative of human disease, show cardinal signs and pathology that resembles after the human ailment and ethically stable. The decision of selection of animal model should be considered precisely since it influences exploratory results and whether results of the research can be sensibly matched with the human. In this way, no specific technique splendidly reproduces the human disease, and relying upon the model, extra cost burden, resources, infrastructure and the necessity for technical hands, should also be kept under consideration. Here we have discussed and compiled various methods of inducing myocardial infarction in animals, basically by surgery, chemicals and through genetic modification, this may benefit the researchers in getting a complied data regarding various methods through which they can induce myocardial infarction in animals.
