Plant-based nanoformulation is one of the novel approaches for therapeutic benefits. This research synthesized a silver nanoparticle from the polyherbal combination of four plants/seeds (Momordica charantia, Trigonella foenum-graecum, Nigella sativa, and Ocimum sanctum) and investigated its antidiabetic effects in streptozotocin-induced Wistar albino rat model. The polyherbal extract (PH) was extracted by the Soxhlet-solvent extraction method and the resulting crude extract was undergone for silver nanoparticle synthesis. The PH extract was subjected to a four-week intervention in fructose-fed streptozotocin-induced Wistar Albino rats’ models and in vitro antioxidative tests. Experimental animals (age: 6–7 weeks, male, body weight: 200–220 g), were divided into five groups including normal control (NC), reference control (RC), diabetic control (DC), and treatment groups PH200, PH100, and PHAgNP20. After three weeks of intervention, body weight, weekly blood glucose level, oral glucose tolerance test, AST, ALT, alkaline phosphatase, total cholesterol, triglycerides, uric acid, urea, and creatinine level of PH200 were found to be significantly (P

Toxoplasma gondii causes a global parasitic disease. Therapeutic options for eradicating toxoplasmosis are limited. In this study, ZnO and Mg-doped ZnO NPs were prepared, and their structural and morphological chrematistics were investigated. The XRD pattern revealed that Mg-doped ZnO NPs have weak crystallinity and a small crystallite size. FTIR and XPS analyses confirmed the integration of Mg ions into the ZnO framework, producing the high-purity Mg-doped ZnO nanocomposite. TEM micrographs determined the particle size of un-doped ZnO in the range of 29 nm, reduced to 23 nm with Mg2+ replacements. ZnO and Mg-doped ZnO NPs significantly decreased the number of brain cysts (p < 0.05) by 29.30% and 35.08%, respectively, compared to the infected untreated group. The administration of ZnO and Mg-doped ZnO NPs revealed a marked histopathological improvement in the brain, liver, and spleen. Furthermore, ZnO and Mg-doped ZnO NPs reduced P53 expression in the cerebral tissue while inducing CD31 expression, which indicated a protective effect against the infection-induced apoptosis and the restoration of balance between free radicals and antioxidant defense activity. In conclusion, the study proved these nanoparticles have antiparasitic, antiapoptotic, and angiogenetic effects. Being nontoxic compounds, these nanoparticles could be promising adjuvants in treating chronic toxoplasmosis.

Neoplasms. Tumors. Oncology. Including cancer and carcinogens ,RC254-282 - Abstract
Abstract Little is known about the role of microRNAs (miRNAs) in rewiring the metabolism within tumours and adjacent non-tumour bearing normal tissue and their potential in cancer therapy. This study aimed to investigate the relationship between deregulated miRNAs and metabolic components in murine duodenal polyps and non-polyp-derived organoids (mPOs and mNPOs) from a double-mutant Apc Min Fbxw7∆G mouse model of intestinal/colorectal cancer (CRC). We analysed the expression of 373 miRNAs and 12 deregulated metabolic genes in mPOs and mNPOs. Our findings revealed miR-135b might target Spock1. Upregulation of SPOCK1 correlated with advanced stages of CRCs. Knockdown of miR-135b decreased the expression level of SPOCK1, glucose consumption and lactic secretion in CRC patient-derived tumours organoids (CRC tPDOs). Increased SPOCK1 induced by miR-135b overexpression promoted the Warburg effect and consequently antitumour effect of 5-fluorouracil. Thus, combination with miR-135b antisense nucleotides may represent a novel strategy to sensitise CRC to the chemo-reagent based treatment.

Medicine ,Science - Abstract
Sixteen fuberidazole derivatives as potential new anticancer bioreductive prodrugs were prepared and characterized. The in vitro anticancer potential was examined to explore their cytotoxic properties by employing apoptosis, DNA damage, and proliferation tests on chosen hypoxic cancer cells. Eight substances (Compound 5a, 5c, 5d, 5e, 5g, 5h, 5i, and 5m) showed promising cytotoxicity values compared to the standard control. The potential of compounds was also examined through in silico studies (against human serum albumin), including chem-informatics, to understand the structure-activity relationship (SAR), pharmacochemical strength, and the mode of interactions responsible for their action. The DFT calculations revealed that only the 5b compound showed the lowest ΔET (2.29 eV) while 5i showed relatively highest βtot (69.89 x 10-31 esu), highest αave (3.18 x 10-23 esu), and dipole moment (6.49 Debye). This study presents a novel class of fuberidazole derivatives with selectivity toward hypoxic cancer cells.

Chronic stable angina pectoris is the primary indication for ranolazine (RZ), an anti-anginal drug. The drug has an anti-ischemic action that is unaffected by either blood pressure or heart rate. Due to the first-pass effect, the drug has a reduced bioavailability of 35 to 50%. The study emphasized developing a novel transdermal drug delivery system of nanostructured lipid carriers (NLCs) for delivering RZ. Many pharmaceutical companies employ lipid nanoparticles as biocompatible carriers for medicinal, cosmetic, and biochemical uses. These carriers are appropriate for many applications, such as topical, transdermal, parenteral, pulmonary, and oral administration, because of the large variety of lipids and surfactants that are readily available for manufacturing. RZ NLCs were made using high-pressure homogenization. Statistical analysis was utilized to find the best formula by varying the concentrations of Precirol ATO 5 (X1), oleic acid (X2), and Tween 80 (X3). Variables such as entrapment effectiveness (EE) (Y1), particle size (Y2), polydispersity index (PDI) (Y3), and zeta potential (Y4) were tested. A variety of tests were performed on the new formulation to ascertain how well it would be absorbed in the body. These tests included in vivo absorption studies, skin permeability assessments, in vitro drug release assessments, and physicochemical analyses. The particle size of RZ-NLCs was shown to be very small (118.4 ± 5.94 nm), with improved EE (88.39 ± 3.1%) and low ZP and PDI (−41.91 ± 0.38 and 0.118 ± 0.028). SEM and TEM analysis confirmed the structure of the NLCs and showed a smooth, spherical surface. Improved RZ-NLCs were used to create NLC gel, which was then tested for elasticity both physically and rheologically. The formulation’s elasticity was investigated. Optimized RZ-NLCs and NLCG were found to have transdermal fluxes of 48.369 g/cm2/h and 38.383 g/cm2/h, respectively. These results showed that the transdermal delivery of RZ distribution through NLC’s transdermal gel had more significant potential. According to in vivo experiments, the drug’s bioavailability in Wistar rats increased when it was delivered through NLCs. The findings demonstrated that NLCs loaded with RZ successfully transported the RZ to the designated site with no interruptions and that a quadratic connection existed between the independent and dependent variables.

In this study, bimetallic nanoparticles (NPs) of silver (Ag) and zinc oxide (ZnO) were synthesized using Leptadenia pyrotechnica leaf extract for the first time. Monometallic NPs were also obtained for comparison. The characterization of the prepared NPs was carried out using various techniques, including UV-Visible spectroscopy (UV-Vis), scanning electron microscopy (SEM), and X-ray diffraction (XRD). The latter confirmed the crystalline nature and diameter of the monometallic and bimetallic NPs of Ag and ZnO. The SEM images of the prepared NPs revealed their different shapes. The biological activities of the NPs were evaluated concerning their antibacterial, antioxidant, and cytotoxic properties. The antibacterial activities were measured using the time-killing method. The results demonstrated that both the monometallic and bimetallic NPs inhibited the growth of Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) bacteria. The antioxidant activities of the NPs were evaluated using the DPPH (2,2-diphenyl-1-picrylhydrazyl) assay and their cytotoxicity was checked using the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The results indicated that the controlled quantity of the monometallic and bimetallic NPs did not affect the viability of the cells. However, the decreased cell (L-929) viability suggested that the NPs could have anticancer properties. Furthermore, the photocatalytic degradation of methyl violet and 4-nitrophenol was investigated using the prepared Ag/ZnO NPs, examining the factors affecting the degradation process and conducting a kinetic and thermodynamic study. The prepared Ag/ZnO NPs demonstrated good photocatalytic degradation (88.9%) of the methyl violet (rate constant of 0.0183 min−1) in comparison to 4-nitrophenol (NPh), with a degradation rate of 81.37% and 0.0172 min−1, respectively. Overall, the bimetallic NPs showed superior antibacterial, antioxidant, cytotoxic, and photocatalytic properties compared to the monometallic NPs of Ag and ZnO.

Abstract In this paper, Jr.NiFe2O4 nanoparticles (NPs) were synthesized first time using the leaves extract of Juglans regia via a straightforward process. The physio and phytochemical analysis of plant confirm the presence of macromolecules which function as bio-reductant and stabilize the nanoparticles. The Jr.NiFe2O4 NPs were characterized by UV–visible, FTIR spectroscopy, PXRD pattern, SEM and TGA/DTA analysis. The nanoparticles proved to be optically active having a value of indirect bandgap of energy in the range of 1.53 eV. The Jr.NiFe2O4 NPs have the ability in scavenging 2,2-diphenyl-1-picrylhydrazyl hydrate (DPPH) free radicals and showed 58.01% ± 1.2% scavenging activity at 100 µg/mL concentrations. The photocatalytic degradation study of ciprofloxacin (CIP) and Congo red (CR) reveals that the highest degradation rate was acquired for CIP using pH = 3, at 254 nm, while 85% of removal rate was analysed for CR. The kinetic studies in case of CR removal followed pseudo-first-order model with thermodynamic parameters (∆G° = − 5.87 kJ mol−1 K, ΔH° = 1393.50 kJ mol−1 and ΔS° = 22.537 kJ mol−1 K) with error analysis. Overall, these data recommend an innovative inspiring application of a plant-mediated synthesis of Jr.NiFe2O4 NPs.

Abstract Background Justicia adhatoda and Ocimum tenuiflorum, locally known as bashok and tulsi, are two ethnomedicinally important herbs that have been using as dietary supplements for several therapeutic applications. This study evaluated the combined effect of both the herbs as an antioxidative and antihyperlipidemic agent. Methods Antihyperlipidemic effect was assessed in a high‐fat diet‐induced hyperlipidemic model in Wistar albino rats. The rats were treated orally with extracts of bashok (J adhatoda, 200 mg/kg bw), tulshi (O tenuiflorum, 200 mg/kg bw), and a combination of bashok and tulshi (50:50), as well as with a reference drug, atorvastatin (10 mg/kg/day), with or without high‐fat diet for 14 days. The antioxidative effect was studied using established in vitro models. The studies were supported by experimentally testing the effects of the extracts on membrane stabilization and inhibition of protein denaturation. Results The results showed that the serum lipid profile was significantly decreased in the different treatment groups, with bashok having the greatest effect. Body weights, total serum protein, LDH, and relative liver and adipose tissue weights were markedly restored towards baseline values, the lowest atherogenic index being achieved with the combined extract. The combination treatment significantly enhanced total phenolic content and antioxidative capacity and greatly potentiated membrane stabilization, but inhibition of protein denaturation was not significantly affected. Conclusion The data demonstrate that a combination of Justicia adhatoda and Ocimum tenuiflorum could be developed as a food supplement with antioxidative and antihyperlipidemic benefits.

Natural biometabolites of plants have been reported to be useful in chronic diseases including diabetes and associated complications. This research is aimed to investigate how the biometabolites of Lasia spinosa methanol stem (MEXLS) extract ameliorative diabetes and diabetes-related complications. MEXLS was examined for in vitro antioxidant and in vivo antidiabetic effects in a streptozotocin-induced diabetes model, and its chemical profiling was done by gas chromatography-mass spectrometry analysis. The results were verified by histopathological examination and in silico ligand-receptor interaction of characterized natural biometabolites with antidiabetic receptor proteins AMPK (PDB ID: 4CFH); PPARγ (PDB ID: 3G9E); and mammalian α-amylase center (PDB ID: 1PPI). The MEXLS was found to show a remarkable α-amylase inhibition (47.45%), strong antioxidant action, and significant (p < 0.05) decrease in blood glucose level, serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), low-density lipoprotein (LDL), urea, uric acid, creatinine, total cholesterol, triglyceride (TG), liver glycogen, creatinine kinase (CK-MB), and lactate dehydrogenase (LDH) and increase in serum insulin, glucose tolerance, and high-density lipoprotein (HDL). Rat’s pancreas and kidney tissues were found to be partially recovered in histopathological analyses. Methyl α-d-galactopyranoside displayed the highest binding affinity with AMPK (docking score, −5.764), PPARγ (docking score, −5.218), and 1PPI (docking score, −5.615) receptors. Data suggest that the MEXLS may be an exciting source to potentiate antidiabetic activities affirming a cell-line study.

Ibuprofen is a well-known non-steroidal anti-inflammatory (NSAID) medicine that is often used to treat inflammation in general. When given orally, it produces gastrointestinal issues which lead to lower patient compliance. Ibuprofen transdermal administration improves both patient compliance and the efficacy of the drug. Nanoconjugation hydrogels were proposed as a controlled transdermal delivery tool for ibuprofen. Six formulations were prepared using different compositions including chitosan, lipids, gum arabic, and polyvinyl alcohol, through ionic interaction, maturation, and freeze–thaw methods. The formulations were characterised by size, drug conjugation efficiency, differential scanning calorimetry (DSC), and Fourier transform infrared spectroscopy (FTIR). Further analysis of optimised hydrogels was performed, including X-ray diffraction (XRD), rheology, gel fraction and swelling ability, in vitro drug release, and in vitro macrophage prostaglandin E2 (PGE2) production testing. The effects of ibuprofen’s electrostatic interaction with a lipid or polymer on the physicochemical and dissolution characterisation of ibuprofen hydrogels were evaluated. The results showed that the S3 (with lipid conjugation) hydrogel provided higher conjugation efficiency and prolonged drug release compared with the S6 hydrogel.

In the present study, naphthyl acetohydrazide (HL) ligand was prepared and used for the synthesis of new six amorphous transition metal (Co(II), Ni(II), Cu(II), Zn(II), Pb(II), Cd(II)) complexes. All the compounds were characterized by elemental analysis, UV-vis, FT-IR, 1H- and 13C-NMR, and Matrix-Assisted Laser Desorption Ionization (MALDI). The solubilization study was carried out by estimating the interaction between the metal complexes with surfactants viz. sodium stearate (SS) and Cetyltrimethylammonium bromide (CTAB). UV-Visible spectroscopy was employed to determine partitioning and binding parameters, whereas electrical conductivity measurements were employed to estimate critical micellar concentration (CMC), the extent of dissociation, and free energy of micellization. The CT-DNA interaction of synthesized compounds with DNA represents the major groove binding. The synthesized ligand and metal complexes were also tested against bacterial and fungal strains and it has been observed that Cu(II) complex is active against all the strains except Candida albicans, while Cd(II) complex is active against all bacterial and fungal strains except Pseudomonas. Among all compounds, only the Pd(II) complex shows reasonable activity against cervical cancer HeLa cell lines, representing 97% inhibition.

The microbial resistance to current antibiotics is increasing day by day, which in turn accelerating the development of new effective drugs. Several studies have proved the high antimicrobial potential of the interaction of several organic ligands with a variety of metal ions. In the present study, a conventional method has been adopted in the synthesis of twelve new heteroleptic complexes of cobalt (II), nickel (II), copper (II) and zinc (II) using three aldimines, namely, (HL1 ((E)-2-((4-chloro-2-hydroxybenzylidene)amino)-3,4-dimethyl-5-phenylcyclopent-2-en-1-one), HL2 ((Z)-3-((4-chlorobenzylidene)amino)-4-hydroxy-5-nitrobenzenesulfonic acid) HL3 (2,2′-((1,2-phenylenebis(azaneylylidene))bis(methaneylylidene))diphenol)) as primary ligands, while phenyl glycine was the secondary ligand. The synthesized compounds were characterized by UV-vis, IR and multinuclear (1H and 13C) NMR spectroscopy, elemental analysis, and electrical conductance. The IR study revealed the coordination of the aldimine derivatives with the -OH and N atom of imine moiety. In contrary to this, the phenyl glycine coordinated to the metal ions via oxygen of carboxylate and nitrogen of the amino group. The spectroscopic analysis unveiled the tetrahedral geometry of the synthesized metal (II) complexes, except for ligand HL3 which exhibited octahedral geometry. The synthesized compounds generally showed antibacterial activity for all microbes, except Ni (II) complexes lacking sensitivity. Furthermore, to access the bioavailability, the synthesized complexes were screened for their solubilization in the micellar media of sodium lauryl sulphate. The metal complex–surfactant interaction was revealed by UV-vis spectroscopy and electrical conductivity measurements.

Nanotechnology is drawing attention nowadays due to its ability to regulate metals into nanosize, ultimately changing metal’s physical, chemical, and optical properties. Silver nanoparticles are known for their potential impact as antimicrobial agents due to their inherent property penetrating the cell wall. The present study aimed to develop and statistically optimise using a novel combination of capsaicin loaded silver nanoparticles (AgCNPs) as an effective anti-bacterial agent to treat psoriasis using a green approach. Ascorbic acid was used as a reducing agent to fabricate silver nanoparticles. The formulation parameters optimisation was conducted using Box-Behnken Design (3×3 factorial design). The loading of capsaicin was confirmed by attenuated total reflectance-fourier transform infrared spectroscopy. Energy-dispersive X-ray spectroscopy-scanning electron microscopy (EDX-SEM) confirmed the existence of silver; net-like structure revealed in SEM and high-resolution transmission electron microscopy further confirmed the nano size of the formulation. Differential scanning calorimetry and X-ray diffraction demonstrated the capsaicin transformed into amorphous after encapsulated. An in-vitro microbial study showed that the 0.10 M formulation of AgCNPs exerted potent anti-bacterial activity, which can be considered an alternative anti-bacterial agent. It also displayed that the zone of inhibition was significantly high in gram-negative bacteria (E. coli) than gram-positive bacteria (S. aureus). Green synthesised AgCNPs showed highly significant anti-bacterial activity, which indicates that this formulation can be very promising for treating psoriasis.

Pregabalin is one of a group of gabapentinoids approved by the Food and Drug Administration (FDA) in 2004. It is a capsule medication taken by mouth that is used for the treatment of neuropathic pain. It is a structural analogue of the neurotransmitter gamma-aminobutyric acid (GABA), and it appears to have a spectrum of benefits and harms similar to those of other adjuvant analgesics used to treat neuropathic pain. The most common side effects mentioned in peripheral neuropathy studies are dizziness and somnolence. Pregabalin could cause liver toxicity by increasing the levels of liver enzymes. It can potentially cause vasodilatation and fluid retention in the heart and blood vessels. It may also lead to addiction. The use of Pregabalin is common among patients with a history of substance abuse and psychoactive drug dependence, as euphoria is one of its main side effects. However, abrupt discontinuation from using Pregabalin may cause nausea, insomnia, or headache. The present review evaluates the significant impact of Pregabalin toxicity on liver and heart in patients and misusers. Keywords: Pregabalin, liver toxicity, alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK), heart failure, addiction.

Graphical abstract, This research investigated the reno-protective effect of Thunbergia laurifolia Linn. (TL) in a lead-induced toxicity test through the modulation of cell signaling pathways. The study carried out to evaluate the effect of TL leaf extracts in Swiss Albino mice exposed to lead acetate (PbAc). Prior to in vivo study, a probable kidney-protective effect of the plant leaf extract was presumed through an activity-specific (PASS) molecular docking analysis. In animal model study, albino mice were divided in seven groups and co-treated with PbAc and TL (100, 200 mg/kgBW) or vitamin E (100 mg/kgBW) for 38 days, whereas the untreated control, TL control, and vehicle control groups received sodium acetate, PbAc, sodium acetate plus mineral oil, respectively. At the end of treatment, blood and kidney tissue were collected for investigating Pb concentration, estimating biochemical profile, evaluating oxidative stress and inflammatory parameters. The histopathological change of kidney along with apoptosis was assessed from kidney sections using H & E staining and TUNEL assay. Pb-exposed mice were found to be increased concentration of Pb in the blood and kidney sample, which further led to increased MDA levels in the plasma, blood, and tissue. Followed by kidney damage, increased expression of TNF-α, iNOS, and COX-2 in kidney tissues were noticed, which were related to elevated TNF-α in the systemic circulation of Pb-treated mice. Co-treatment with TL or vitamin E significantly reduced altered structure and apoptosis of kidney tissues. Downregulation of inflammatory markers especially TNF-α, iNOS, and COX-2 with simultaneous improvement of renal function through reduced plasma BUN and creatinine levels demonstrate that TL act as a potential dietary supplement to detoxify Pb in kidney showing an antioxidant and anti-inflammatory effect.

The current study investigated the immunomodulating and osteoblast differentiation potential of the natural compounds from Leea macrophylla (LMN). Immunomodulatory effects have been investigated by the phagocytosis of Candida albicans using polymorphonuclear neutrophil cells in the in vitro slide method. A bioactivity-guided fractionation technique was used to evaluate the stimulating effect of L. macrophylla methanol extract on osteoblast differentiation using mouse osteoblastic cells. A low dose of LMN was found to stimulate the phagocytic effect better than a higher dose. The natural compounds from L. macrophylla have significantly increased alkaline phosphatase (ALP) and osteocalcin activities. The LMN promoted the osteoblast differentiation through upregulation of ALP, osteocalcin, and type 1 collagen in a dose-dependent manner. These natural compounds also upregulated ALP, osteocalcin, and type 1 collagen gene expressions. The data suggest that LMN has potential anabolic sequel on bone formation and osteoblast differentiation.

This research investigated pharmacological properties mainly the anti-inflammatory, anthelmintic, thrombolytic and anxiolytic potential of methanol extract of Syzygium samarangense (MESS) var. parviflorum. Anti-inflammatory action by bovine serum albumin, egg albumin denaturation and membrane stabilization, anthelmintic by live parasites, thrombolytic by clot lysis and anxiolytic by elevated plus maze (EPM) and light and dark box (LDB) tests were measured. The four targeted pharmacological properties were further justified using the most prevalent compounds, isolated from this plant, to be undergone for their pharmacokinetic property’s analyses, sitemap analyses and lignad-receptor interactions by computational models through SwissADME and Schrödinger, 2018 softwares against PDB 6COX, 6D6T, 1JFF receptors. MESS was found to display statistically significant (P < 0.05) inhibition of Bovine Serum albumin and Egg albumin denaturation compared to reference drug diclofenac sodium. Remarkable vermicidal effect on the paralysis and death of anthelmintic parasites was observed at MESS concentration 200 mg/dL. A nondescript clot lysis of MESS compared to streptokinase was evident in in vitro thrombolytic assay. MESS increased the number of times the animal crossed from one compartment to the other and the time spent in the brightly-lit chamber of the LDB. Three-methylchalcone derivatives out of seven MESS compounds were undertaken, based on cut off value and sitemap prediction score, for further ligand-receptor binding efficiency. All these three compounds showed promising docking score, glide emodel and glide energy against PDB 6COX, 6D6T and 1DDJ, plasmin proteins demonstrating the prospects of MESS to be materialized for anti-inflammatory, anthelmintic, and thrombolytic therapeutics with further clarification.

Antipsychotics (APs) are widely used medications with reported diabetogenic side effects. This study investigated the effect of commonly used APs, namely chlorpromazine (CPZ), haloperidol (HAL) and clozapine, on the bioenergetics of male CD1 mice isolated pancreatic beta cells as an underlying mechanism of their diabetogenic effects. The effect of APs on Alamar blue reduction, adenosine triphosphate (ATP) production and glucose-stimulated insulin secretion (GSIS) of isolated beta cells was evaluated. Then, the effects of APs on the activities of mitochondrial complexes and their common coding genes expression, oxygen consumption rate (OCR), mitochondrial membrane potential (MMP) and lactate production were investigated. The effects of APs on the mitochondrial membrane fluidity (MMF) and mitochondrial membrane fatty acid composition were also examined. Results showed that the tested APs significantly decreased cellular ATP production and GSIS of the beta cells. The APs significantly inhibited the activities of mitochondrial complexes and their coding gene expression, MMP and OCR of the treated cells, with a parallel increase in lactate production to different extents with the different APs. CPZ and HAL showed increased MMF and mitochondrial membrane polyunsaturated fatty acid content. In conclusion, the tested APs-induced mitochondrial disruption can play a role in their diabetogenic side effect.

A number of plant-derived drugs have been prescribed for treating atherothrombotic disorders such as myocardial or cerebral infarction. Therefore, this study investigated the individual and combined antithrombotic effects of six Asian plants on individuals with various BMIs. Venous blood drawn from healthy volunteers was allowed to form clots and treated with six organic fractions of Ophiorrhiza harrisiana Heyne, Haldina cordifolia (Roxb.) Ridsdale, Eclipta alba (L.) Hassk, Syzygium operculatum L., Lantana camara L., and Acanthus ilicifolius Linn. using the clot-lysis method. The weight of the clot before and after treatment provided the percentage of clot lysis. Variations in clot lysis in different BMI groups were assessed. A. ilicifolius induced the most thrombolytic activity, whereas L. camara showed slightly lower thrombolytic activity. The maximum clot-lysis activity was primarily observed in different fractions of O. harrisana, H. cordifolia, E. alba, S. operculatum, and A. ilicifolius. However, chloroform fractions of all plants except O. harrisana and L. camara showed maximum activity in individual plants. O. harrisana, H. cordifolia, E. alba, S. operculatum, L. camara, and A. ilicifolius showed the highest significant (P < 0.5 and P < 0.001) clotlysis activity viz., 46.60±0.79% (ethyl acetate), 55.40±1.023% (chloroform), 48.86±1.35% (CCl4 ), 44.89±1.76% (chloroform), 29.17±1.12% (ethanol), and 56.318±1.64% (chloroform). Obtained results were verified by ligandreceptor interaction through in silico approach. In conclusion, H. cordifolia, E. alba, and A. ilicifolius demonstrated promising thrombolytic effects; therefore, it is recommended that they be studied further for their therapeutic potential.

Pharmaceutical Science - Abstract
Background: The antiretroviral protease inhibitor drug lopinavir (LPV) is used to treat HIV-1 infection. LPV is known to have limited oral bioavailability, which may be attributed to its poor aqueous solubility, low efficacy and high first-pass metabolism. Self-nanoemulsifying drug delivery systems (SNEDDS) for LPV have been developed and optimised to counter the current issues. Methods: The titration method was used to prepare LPV-loaded SNEDDS (LPV-SNEDDS). Six different pseudo-ternary phase diagrams were constructed to identify the nanoemulsifying region. The developed formulations were chosen in terms of globule size < 100 nm, dispersity ≤ 0.5, dispersibility (Grade A) and % transmittance > 85. Heating-cooling cycle, freeze-thaw cycle, and centrifugation studies were performed to confirm the stability of the developed SNEDDS. Results: The final LPV-SNEDDS (L-14) droplet size was 58.18 ± 0.62 nm, with polydispersity index, zeta potential, and entrapment efficiency (EE%) values of 0.326 ± 0.005, -22.08 ± 1.2 mV, and 98.93 ± 1.18%, respectively. According to high-resolution transmission electron microscopy (HRTEM) analysis, the droplets in the optimised formulation were < 60 nm in size. The selected SNEDDS released nearly 99% of the LPV within 30 min, which was significantly (p < 0.05) higher than the LPV-suspension in methylcellulose (0.5% w/v). It indicates the potential use of SNEDDS to enhance the solubility of LPV, which eventually could help improve the oral bioavailability of LPV. The Caco-2 cellular uptake study showed a significantly (p < 0.05) higher LPV uptake from the SNEEDS (LPV-SNEDDS-L-14) than the free LPV (LPV-suspension). Conclusion: The LPV-SNEDDS could be a potential carrier for LPV oral delivery.

The authors thank The Islamia University of Bahawalpur for providing basic facilities. The degradation of dyes is a difficult task due to their persistent and stable nature; therefore, developing materials with desirable properties to degrade dyes is an important area of research. In the present study, we propose a simple, one-pot mechanochemical approach to synthesize CuO nanoparticles (NPs) using the leaf extract of Seriphidium oliverianum, as a reducing and stabilizing agent. The CuO NPs were characterized via X-ray diffraction (XRD), scanning electron microscopy (SEM), photoluminescence (PL) and Fourier-transform infrared spectroscopy (FTIR). The photocatalytic activity of CuO NPs was monitored using ultraviolet-visible (UV-Vis) spectroscopy. The CuO NPs exhibited high potential for the degradation of water-soluble industrial dyes. The degradation rates for methyl green (MG) and methyl orange (MO) were 65.231% ± 0.242 and 65.078% ± 0.392, respectively. Bio-mechanochemically synthesized CuO NPs proved to be good candidates for efficiently removing dyes from water publishersversion published

Diabetic nephropathy (DN) is a major risk factor for end-stage renal disease (ESRD). MicroRNAs (miRNAs/miRs) and their variants may be implicated in health and disease, including DN. The present study aimed to investigate the association of the miRNA-499a gene (MIR499A) A/G seed region variant (rs3746444) with DN-associated ESRD susceptibility in patients with diabetes mellitus, and to determine whether there was an association between the different genotypes and the patients' laboratory and clinical data. A case-control pilot study was conducted on 180 adult patients with type 2 diabetes mellitus. A total of 90 patients with ESRD on regular hemodialysis were considered as the cases, and 90 age-, sex- and ethnicity-matched diabetic patients with normo-albuminuria were considered as the controls. MIR499A genotyping was performed using a TaqMan Real-Time allele discrimination assay. Results demonstrated that the MIR499A rs3746444*G variant conferred susceptibility to the development of ESRD under co-dominant [(odds ratio (95% confidence interval): 2.49 (1.41-3.89) and 2.41 (1.61-6.68) for heterozygous and homozygous comparison, respectively], dominant [2.30 (1.18-3.90)] and allelic [1.82 (1.17-2.83)] models. Different genotypes of the specified variant did not exhibit significant associations with the clinic-laboratory data of the studied patients or the circulating miR-499a plasma levels. In conclusion, results of the present study suggested that MIR499A rs3746444 may be a susceptibility variant for DN-associated ESRD in the study population. However, larger sample size studies with different ethnicities are warranted to verify these findings.

Marine algae are ecologically important in the food chain and some of have demonstrated wide range of pharmacological properties including antidiabetic activities. This research was aimed to investigate the diabetes-healing effect of a phytochemically active marine alga Padina tenuis. Prior to the in vivo study, both qualitative and quantitative phytochemical status, acute toxicity and antioxidative effects by DPPH radical scavenging assay, ferric reducing assay, superoxide scavenging assay, iron chelating assay were evaluated. The in vivo study was conducted in 10% fructose-fed streptozotocin-induced diabetic rats categorized into five different groups including normal control (NC), diabetic control (DC), reference control (RC), treatments PT-25 (Padina tenuis chloroform extract 25 mg/kg b.w.) and PT-50. Upon routine observation on body weight, food intake, water intake, blood glucose, and oral glucose tolerance (OGT), the animals were sacrificed after three weeks of intervention. Organ weights, serum lipid profile, insulin, alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), creatinine, uric acid and urea were calculated as major indices. The results showed very promising phenolic and flavonoid content, substantial antioxidative effect, non-toxicity in acute level and strong α-amylase inhibition. PT-25 was found to significantly manage the serum AST, ALP, creatinine, uric acid, weekly blood glucose level, glucose tolerance ability as well as kidney and pancreatic weights. Moreover, kidney and pancreatic architecture in histopathological screening were notably improved in the treatment group. β-cells/islet of Langerhans and kidney cells were improved compared to NC animals. The data suggests that Padina tenuis could be very effective as natural sources of antidiabetic agents to modulate pancreatic action and kidney function.

In the present study, naphthyl acetohydrazide (HL) ligand was prepared and used for the synthesis of new six amorphous transition metal (Co(II), Ni(II), Cu(II), Zn(II), Pb(II), Cd(II)) complexes. All the compounds were characterized by elemental analysis, UV-vis, FT-IR, 1H- and 13C-NMR, and Matrix-Assisted Laser Desorption Ionization (MALDI). The solubilization study was carried out by estimating the interaction between the metal complexes with surfactants viz. sodium stearate (SS) and Cetyltrimethylammonium bromide (CTAB). UV-Visible spectroscopy was employed to determine partitioning and binding parameters, whereas electrical conductivity measurements were employed to estimate critical micellar concentration (CMC), the extent of dissociation, and free energy of micellization. The CT-DNA interaction of synthesized compounds with DNA represents the major groove binding. The synthesized ligand and metal complexes were also tested against bacterial and fungal strains and it has been observed that Cu(II) complex is active against all the strains except Candida albicans, while Cd(II) complex is active against all bacterial and fungal strains except Pseudomonas. Among all compounds, only the Pd(II) complex shows reasonable activity against cervical cancer HeLa cell lines, representing 97% inhibition.

COVID-19 is considered as the most challenging in the current situation but lung cancer is also the leading cause of death in the global population. These two malignancies are among the leading human diseases and are highly complex in terms of diagnostic and therapeutic approaches as well as the most frequent and highly complex and heterogeneous in nature. Based on the latest update, it is known that the patients suffering from lung cancer, are considered to be significantly at higher risk of COVID-19 infection in terms of survival and there are a number of evidences which support the hypothesis that these diseases may share the same functions and functional components. Multi-level unwanted alterations such as (epi-)genetic alterations, changes at the transcriptional level, and altered signaling pathways (receptor, cytoplasmic, and nuclear level) are the major sources which promote a number of complex diseases and such heterogeneous level of complexities are considered as the major barrier in the development of therapeutics. With so many challenges, it is critical to understand the relationships and the common shared aberrations between them which is difficult to unravel and understand. A simple approach has been applied for this study where differential gene expression analysis, pathway enrichment, and network level understanding are carried out. Since, gene expression changes and genomic alterations are related to the COVID-19 and lung cancer but their pattern varies significantly. Based on the recent studies, it appears that the patients suffering from lung cancer and and simultaneously infected with COVID-19, then survival chance is lessened. So, we have designed our goal to understand the genes commonly overexpressed and commonly enriched pathways in case of COVID-19 and lung cancer. For this purpose, we have presented the summarized review of the previous works where the pathogenesis of lung cancer and COVID-19 infection have been focused and we have also presented the new finding of our analysis. So, this work not only presents the review work but also the research work. This review and research study leads to the conclusion that growth promoting pathways (EGFR, Ras, and PI3K), growth inhibitory pathways (p53 and STK11), apoptotic pathways (Bcl- 2/Bax/Fas), and DDR pathways and genes are commonly and dominantly altered in both the cases COVID-19 and lung cancer.

The IL6/JAK2/STAT3 axis dysregulation and the related downstream pathways are a major contributor to the progression of non-small-cell lung carcinoma (NSCLC) and mainly affect apoptosis. Furthermore, tubulin inhibitors are potential chemotherapeutic agents against NSCLC. In this study, we have provided new molecular insights into the antiproliferative activity of six 3β-acetoxy-5α-androstane heterocycle compounds against NSCLC. The cell line A549, which represents a good model of NSCLC, was used to evaluate the antitumour activity of tested androstane derivatives, and non-cancerous gingival mesenchymal stem cell line (GMSC) were used to assess the specificity and toxicity of the tested compounds. Further on, molecular docking predictions were used to determine the molecular targets for the most promising cytotoxic compound. To assess apoptosis and cell cycle progression in treated A549 cells, flow cytometry was used. RT-qPCR and ELISA analyses were used to gain deep insights into cellular and molecular mechanisms. Results revealed that compound

Carbamazepine (CBZ) is a widely employed anti-seizure medication that crosses the blood-brain barrier (BBB) to exert its anti-convulsant action. The effects of CBZ on components of the BBB have yet to be completely delineated. Hence the current study evaluated the effects of CBZ upon mitochondrial functionality of BBB-derived microvascular endothelial cells isolated from Albino rats. The influence of CBZ on cell viability and barrier functions were evaluated by 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT), lactate dehydrogenase, and electrophysiological assays over a drug concentration range of 0.1–1000 μM. Bioenergetics effects were measured via ATP production, mitochondrial complexes I and III activities, lactate production, and oxygen consumption rates (OCRs), and mitochondrial membrane potential, fluidity and lipid content. CBZ was cytotoxic to microvascular endothelial cells in a concentration and duration dependent manner. CBZ significantly diminished the endothelial cell’s barrier functions, and impacted upon cellular bioenergetics: reducing mitochondrial complex activities with a parallel decrease in OCRs and increased anaerobic lactate production. CBZ significantly decreased mitochondrial membrane potential and induced an increase of membrane fluidity and decrease in levels of mitochondrial saturated and unsaturated fatty acids. In summary, CBZ disrupted functional activity of BBB endothelial cells via damage and modification of mitochondria functionality at therapeutically relevant concentrations.

Degranulation of mast cells and basophils occurs after the cross-linking of FceRI receptor-bound IgE by multivalent allergens, resulting in the release of a range of de novo synthesized and preformed mediators of the allergic response. β-Hexosaminidase release is usually measured as a simple readout for degranulation. Furthermore, the rat basophilic leukemia (RBL)-2H3 cell line is commonly used for measuring degranulation, monitoring β-hexosaminidase release. Here, we describe surface-engineered and modified nanoparticles with specific ligands in order to study the signaling and cellular responses of the RBL-2H3 cell line.

The cancer-brake gene CTLA4 has a vital function in suppressing the immune responses of activated T lymphocytes. Numerous reports explored the impact of various CTLA4 variants with the predisposition for malignancies but with unconvincing findings. Hence, this study is designed to assess the association of CTLA4 (c.49AG, rs231775) variant with the outcome of breast carcinoma. A total of 272 participants (93 BC patients and 179 cancer-free healthy volunteers) were enrolled. Genomic DNA for all participants was genotyped for CTLA4 (c.49AG) variant via TaqMan genotyping assay. Patients with A/G genotype conferred protection against developing BC under heterozygote comparison (OR = 0.56, 95%CI = 0.31-0.98) as well dominant model (OR = 0.55, 95%CI = 0.32-0.97). AG/GG genotypes were anchored with an increased risk of nodal infiltration (OR = 2.90, 95%CI = 1.03-8.17, P = 0.037), metastasis (OR = 4.46, 95%CI = 1.18-16.8, P = 0.019), advanced clinical stage (OR = 6.54, 95%CI = 2.06-20.75, P 0.001), recurrence (OR = 5.2, 95%CI = 1.73-15.7, P = 0.001), and shorter survival (OR = 2.54, 95%CI = 1.08-5.99, P = 0.032). In addition, functional enrichment analysis revealed the key role of CTLA4 in cancer immunosurveillance. Our findings indicated that the CTLA4 c.49AG variant might have prognostic as well diagnostic impact in breast cancer.

Worldwide, cancer is still an area with high unmet medical need. Lead optimization efforts towards structure-based drug design were employed to discover newly synthesized hetero-steroid derivatives with promising anticancer effects against hepatocellular carcinoma (HCC). The aim of our study is to evaluate the anti-proliferative activity and the mechanism, a dual PI3K/mTOR inhibitor, and mechanism of action of a series of heterocylic androstane derivatives as anti-HCC agent. The cytotoxic effects of different heterocylic androstanes and 5FU as single agents, were assessed against both HepG2 cells and Non-malignant MDCK cell line to assess the toxicity. Then the underlying mechanism of compound 4 as most promising compound was evaluated using molecular docking, MTT assay, cell cycle analysis, DNA fragmentation, and real-time PCR. The results of MTT assay showed potential cytotoxic effect for compound 4 and 5 against liver cancer cell line with IC50 value 39.81 and 57.54 μM, respectively. Inhibition of the PI3K/AKT/mTOR pathway was achieved by compound 4, which was documented by molecular docking and augmented by gene expression analysis. Detailed mechanism revealed that compound 4 induced cell cycle arrest, DNA fragmentation, and induction of apoptosis by inhibition of anti-apoptotic genes, and upregulation of apoptotic genes. Our results shed a light on aminopyrazoloandrostane derivative 4 as an inhibitor of the PI3K/AKT/mTOR pathway, which might be acting as promising anti-liver cancer agent. Our data support further investigation of agents targeting the PI3K/AKT/mTOR.
