(Elsevier B.V., 2023-03-25T00:00:00) Amanat, Muhammed; Shahid Ud Daula, A.F.M.; Singh, Randhir
Introduction: The rhizomes of Zingiber roseum plant have been used in traditional medicine to treat several ailments. Regardless of worth, no research has accounted its toxicity potential. So, the study was designed to determine safety and toxicity potential of Zingiber roseum rhizomes (ZRR) in acute oral toxicity model in swiss albino mice. Methods: Acute oral toxicity was assessed as per the guidelines of �The Brazilian Agency of National Health Surveillance'. In an acute toxicity investigation, 300 mg/kg, 600 mg/kg, and 1200 mg/kg of ZRR extract was orally administered to mice. Thereafter, the animals were monitored for 14 days. To analyze any potential toxicity, general behavior of animals, clinical symptoms of poisoning, body weight, biochemical and hematological marker, and liver histology was carried out. Results: Oral dosing of 300, 600, and 1200 mg/kg of crude extract did not produce mortality or any adverse effect in the laboratory animals. The control and treatment groups of mice exhibited similar behavioral characteristics, neurological signs and total body weight during the treatment period of 14 days. The markers of liver damage i.e., ALT and AST, total serum protein, and albumin did not show any significant change between extract-treated and control mice. The extracts also significantly suppressed ALP activity as compared to control. Kidney function was assessed in mice by measuring creatinine and urea level and no change was observed in level of creatinine and urea in experimental animals. Moreover, no alterations were observed in hematological markers and lipid profile (triglyceride and total cholesterol level). In addition, the liver showed normal architecture and no significant adverse consequences on histopathology analysis. Discussion & conclusion: These outcomes propose that LD50 of rhizomes of Z. roseum is higher than 1200 mg/kg b.w. and might be possibly safe for consumption. � 2023 The Author(s)

Tardive dyskinesia (TD) is a hyperkinetic movement disorder that displays unusual involuntary movement along with orofacial dysfunction. It is predominantly associated with the long-term use of antipsychotic medications, particularly typical or first-generation antipsychotic drugs such as haloperidol. Oxidative stress, mitochondrial dysfunction, neuroinflammation, and apoptosis are major pathophysiological mechanisms of TD. The BCG vaccine has been reported to suppress inflammation, oxidative stress, and apoptosis and exert neuroprotection via several mechanisms. Our study aimed to confirm the neuroprotective effect of the BCG vaccine against haloperidol-induced TD-like symptoms in rats. The rats were given haloperidol (1 mg/kg, i.p.) for 21 days after 1 h single administration of the BCG vaccine (2 � 107 cfu). Various behavioral parameters for orofacial dyskinesia and locomotor activity were assessed on the 14th and 21st days after haloperidol injection. On the 22nd day, all rats were euthanized, and the striatum was isolated to estimate the biochemical, apoptotic, inflammatory, and neurotransmitter levels. The administration of the BCG vaccine reversed orofacial dyskinesia and improved motor function in regard to haloperidol-induced TD-like symptoms in rats. The BCG vaccine also enhanced the levels of antioxidant enzymes (SOD, GSH) and reduced prooxidants (MDA, nitrite) and pro-apoptotic markers (Cas-3, Cas-6, Cas-9) in rat brains. Besides this, BCG treatment also restored the neurotransmitter (DA, NE, 5-HT) levels and decreased the levels of HVA in the striatum. The study findings suggest that the BCG vaccine has antioxidant, antiapoptotic, and neuromodulatory properties that could be relevant in the management of TD.

Background: Cucurbita pepo (C. pepo) is cultivated and used traditionally as vegetable as well as medicine in different parts of the world. The aim of current study was to investigate the potential of C. pepo in attenuation of diabetic neuropathy via using streptozotocin (STZ)-induced diabetes model in male wistar rats. Materials and Methods: Diabetic neuropathy was induced by administration of STZ; 65�mg/kg, i.p. and Nicotinamide (NAD; 230�mg/kg i.p.) and assessed by measuring thermal hyperalgesia, mechanical hyperalgesia and motor nerve conduction velocity (MNCV) in experimental animals. Treatment with different doses of (100, 200 and 400�mg/kg, p.o.) petroleum ether extract of C. pepo (CPE) and hydroethanolic extract of C. pepo (CHE) was started from the 60th day of STZ/NAD administration and continued upto 90th day. Results: CPE and CHE significantly attenuated the behavioural changes including hyperalgesia, allodynia and MNCV linked to diabetic neuropathy. Moreover, the oxidative stress and level of TNF-?, TGF-? and IL-1? was found to be significantly attenuated in experimental animals. Conclusion: Thus C. pepo might ameliorate the progression of diabetic neuropathy via modulation of chronic hyperglycemia and therefore and have therapeutic potential for treatment of diabetic neuropathic pain. � 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

(John Wiley and Sons Inc, 2022-01-22T00:00:00) Aggarwal, Ranjana; Swati, S.; Kumar, Vinod; Singh, Randhir; Kajal, Anu; Saini, Deepika
A series of structurally diverse N-[1-(6?-chloropyridazin-3?-yl)-3-(4?-substitutedphenyl)-1H-pyrazole-5-yl]alkanamides 5(a�r) has been designed and synthesized via Aliquat 336 catalyzed amidation of 5-amino-3-aryl-1-(6?-chloropyridazin-3?-yl)pyrazoles 3(a�c). The target compounds were designed on basis of the results obtained from the study of Lipinski's rule of five and binding interactions with target protein 3LN1. Eventually, compounds 5(a�r) were screened for their in vitro anti-inflammatory action by using inhibition of albumin denaturation and membrane stabilization assay. It has been found that all the synthesized compounds obeyed Lipinski's rule of five (nviolations�=�0�1) and showed weak to strong binding interactions with dock score range ?8.0 to ?9.9�kcal/mol. All alkanamides exhibited moderate to excellent activity as compared to the standard drug, Aspirin. Interestingly, the results indicated that the compound 5a may act as a promising medicinal lead as an anti-inflammatory agent for in vivo and clinical testing in future. � 2022 Wiley Periodicals LLC.

(Bentham Science Publishers, 2022-08-18T00:00:00) Sharma, Prerna; Rani, Nidhi; Gangwar, Aishwarya; Singh, Randhir; Kaur, Rajwinder; Upadhyaya, Kumud
Diabetes mellitus is a crucial health issue worldwide. The worldwide ubiquity is 8.8% among adults, which is predicted to rise to 10.4% by 2040. Diabetic neuropathy is a long-term complication associated with the diabetes mellitus condition, which primarily targets Schwann cells, peripheral axons and cell bodies (perikarya) in DRG (dorsal root ganglia). It can be accom-panied by different factors such as metabolic factors such as insulin resistance, hypertension, obe-sity, low HDL level, and hypertriglyceridemia. The etiology of DPN is multifactorial. It is caused by hyperglycemia, micro-angiopathy, HbA1c, duration of diabetes, smoking status, high-density lipoprotein cholesterol and hypertension. Also, increased glucose conditions decrease vitamin D levels. Vitamin D, which is involved in neurotrophins such as NGF (nerve growth factor) and NCH (neuronal calcium homeostasis), plays a neuroprotective role in peripheral nerves. Depletionleads to vitamin D deficiency which further develops peripheral neuropathy in diabetic patients. Accu-mulation of AGEs (advanced glycation end product) plays a significant role in the pathogenesis of sensory neuronal damage. It contributes to microangiopathy and endoneurial vascular dysfunction in peripheral nerves. With vitamin D supplementation, the neuropathy pain scores were improved. � 2023 Bentham Science Publishers.

This review focuses on graphene and its derivatives and their function in nanomedicine, in particularly the transport of drugs and biomolecules, as well as in the future trends and challenges associated with graphene-based materials. � 2023 Elsevier B.V.
Exploring the role of exosomes in rheumatoid arthritis
(Springer Science and Business Media Deutschland GmbH, 2022-11-22T00:00:00) Singh, Anuja; Behl, Tapan; Sehgal, Aayush; Singh, Sukhbir; Sharma, Neelam; Naqwi, Maaz; Mavi, Anil; Singh, Randhir
In prosperous countries, autoimmune illnesses affect minimum 7% of the community. Rheumatoid Arthritis (RA) as an autoimmune illness is thought to be induced through a variety of genomic, physiological, and biological factors. Many experts in the field of nanomedicine have looked to stem cells as a viable strategy to repair human tissue; however, exosomes have demonstrated greater potential in recent years. Exosomes, produced from stem cells in particular, have exhibited a high propensity to give therapeutic effects. To resist local cellular stress, they are secreted in a paracrine manner from cells. As a result, exosomes produced from stem cells can provide enormous health uses. If treatment is not given, autoantibodies produce synovial inflammation and arthritis, which can lead to chronic inflammation, and impairment. Exosomes could be administered for the treatment of RA, by acting as therapeutic vectors. Exosomes are murine extracellular vesicles that influence biological mechanisms and signal transduction by transporting genetic and protein components. Diseases like RA and bone fractures could be treated using cell-free therapeutic strategies if exosomes could be isolated from stem cells efficiently and packaged with specific restorative substances. To get to this position, many breakthroughs must be achieved, and the following review summarises the most recent developments in stem cell-derived exosomes, with a focus on the important literature on exosome dynamics in RA.

Background and aim: The ingredients viz., Artemisia roxburghiana, Cissampelos pareira, Stephania glabra, Drimia indica, Roylea cinerea, Tinospora sinensis and Curcuma longa of the present formulation are used to treat diabetes in the Indian traditional medical system. Adopting the concept of multiple herbal mixtures for better therapeutic effects from the ancient Ayurvedic text Sarangdhar Samhita, the present study aimed to develop a polyherbal formulation (PHF) of seven herbs and to evaluate its sodium-glucose cotransporter protein-2 (SGLT2) inhibitory effect on type 2 diabetic rats. Experimental procedure: Streptozotocin (STZ) (60 mg/kg) and nicotinamide (NAM) (120 mg/kg) were intraperitoneally administered to induce type 2 diabetes in Wistar rats. The animals were divided into 5 groups viz. normal control, diabetic control, positive control (dapagliflozin at 0.1 mg/kg) and two test groups (PHF at 250 and 500 mg/kg). Various parameters including blood glucose, serum glutamic pyruvic transaminase (SGPT), serum glutamic-oxaloacetic transaminase (SGOT), bilirubin, triglycerides and creatinine were measured. Results and conclusion: The treatment with PHF (250 and 500 mg/kg) showed a significant (p < 0.05) decrease in blood glucose levels by 56.37% and 58.17%, respectively. The levels of SGOT, SGPT and bilirubin were significantly reduced in PHF-fed diabetic rats. Histopathological examination revealed no major changes in the treated groups as compared to the normal control. The molecular docking study showed strong binding of ?-sitosterol, insulanoline, warifteine, dehydrocorydalmine, taraxerol acetate, lupeol, corydalmine and luteolin to SGLT2 protein. The present study concludes that PHF has promising antidiabetic activity via inhibiting SGLT2 protein without showing any adverse effects. � 2022 Center for Food and Biomolecules, National Taiwan University
Galangin, as a Potential Anticancer Agent
(Springer Science and Business Media Deutschland GmbH, 2022-04-07T00:00:00) Singh, Dhirendra; Saini, Arpit; Singh, Randhir; Agrawal, Rohini
Cancer is a major global health issue and one of the main causes of mortality worldwide. In recent years, cancer mortality and morbidity rates have risen dramatically due to variety of factors. Despite therapeutic alternatives, chemotherapy medications have major adverse effects and many kinds of drug resistance that severely diminish their effectiveness. Galangin, 3,5,7-trihydroxyflavone, is considered as the bioactive constituent of galangal and honey. In general, galangin exhibits several pharmacological effects, such as anti-inflammatory, antioxidant, anticancer, and antiviral activities. The anticancer effects of galangin are mostly due to its abilities to inhibit cell cycle progression, inhibiting mitogen-activated protein kinase (MAPK), protein kinase B (Akt), or mammalian target of rapamycin (mTOR) activity leading to apoptotic cell death by stimulating caspase-9/8/3 and inhibiting tumor invasion and metastasis by decreasing the upregulation of matrix metalloproteinase-2/-9 (MMP-2/-9). These molecular pathways of galangin are involved in suppressing different malignancies, such as lung cancer, hepatic cancer, breast cancer, ovarian cancer, gastric cancer, colorectal cancer, retinoblastoma, and osteosarcoma. The present work is emphasized on the anticancer mechanisms of galangin. [Figure not available: see fulltext.]. � 2022, The Author(s) under exclusive licence to Sociedade Brasileira de Farmacognosia.

Monkeypox is a zoonotic illness caused by the monkeypox virus (MPXV) that has a similar etiology to smallpox. The first case of monkeypox was reported in Western and Central Africa in 1971, and in 2003, there was an outbreak of monkeypox viruses outside Africa. According to the World Health Organization (WHO) and Center for Disease Control and Prevention (CDC), monkeypox is transmitted through direct contact with infected animals or persons exposed to infectious sores, scabs, or body fluids. Also, intimate contact between people during sex, kissing, cuddling, or touching parts of the body can result in the spreading of this disease. The use of the smallpox vaccine against monkeypox has several challenges and hence anti-virals such as cidofovir, brincidofovir, and tecovirimat have been used for the symptomatic relief of patients and reversing the lesion formation on the skin. Despite the recent outbreak of monkeypox most especially in hitherto non-endemic countries, there is still a lack of definitive treatment for monkeypox. In the present review, emphasis was focused on etiopathology, transmission, currently available therapeutic agents, and future targets that could be explored to halt the progression of monkeypox. From our review we can postulate that owing to the lack of a definitive cure to this reemerging disorder, there is a need for general awareness about the transmission as well as to develop appropriate diagnostic procedures, immunizations, and antiviral medication. � 2022 Elsevier B.V.

Nutritional intakes, homeostasis of glucose and also of electrolytes, are controlled by the central nervous system which triggers the various sensations. Certain risks are associated with malnutrition that may have severe effects and are a major cause of neurological diseases. About 792 million people from chronic food deficiencies are influenced in the whole world. Acute neurological patients may have a wide range of enhanced metabolism and catabolism seen due to long-term fasting. Acute neurological diseases include spinal cord injuries, traumatic brain injury, cancer, and cerebral vascular accident hemorrhagic or ischemic, whereas chronic neurological diseases include Parkinson's disease, several dementia's and Alzheimer's disease, and amyotrophic lateral sclerosis. Treatment options must include the nutritional evaluation periodically. Also, to rectify the nitrogen balance depletion, intake of nutrition must be enhanced and hyper alimentation must be avoided. � 2023 Elsevier Inc. All rights reserved.
