ABSTRACT

The ethanolic extract of Coleus forskohlii Briq leaves was employed in the green synthesis of zinc nanoparticles (Zn-NPs) by an immediate, one-step, and cost-effective method in the present study. Zn-NPs were coated with purified bovine lactoferrin (LF) and characterized through different instrumental analysis. The biosynthesized Zn-NPs were white in color revealing oval to spherical-shaped particles with an average size of 77 ± 5.50 nm, whereas LF-coated Zn-NPs (LF-Zn-NPs) revealed a larger particles size of up to 98 ± 6.40 nm. The biosynthesized Zn-NPs and LF-Zn-NPs revealed negatively charged surfaces with zeta-potentials of - 20.25 ± 0.35 and - 44.3 ± 3.25 mV, respectively. Interestingly, the LF-Zn-NPs showed potent in vitro retardation for SARS-CoV-2 entry to host cells by binding to the ACE2-receptor and spike protein receptor binding domain at IC50 values of 59.66 and µg/mL, respectively. Additionally, the results indicated the ability of LF-Zn-NPs to inhibit SARS-CoV-2 replication by interfering with RNA-dependent RNA polymerase "RdRp" activity at IC50 of 49.23 µg/mL. In vivo, the LF-Zn-NPs displayed a protective and therapeutic activity against induced pulmonary fibrosis in Bleomycin-treated male albino rats owing to its anti-inflammatory, antioxidant, and significant reduction in CRP, LDH, ferritin, and D-dimer levels. The obtained findings offer a promising route for biosynthesized Zn-NPs and LF-Zn-NPs as promising candidates against COVID-19.

ABSTRACT

Colorectal cancer (CRC) is a malignant tumor recognized as a major cause of morbidity and mortality throughout the world. Therefore, novel liposomes of oleic acid coated with camel α-lactalbumin (α-LA coated liposomes) were developed for their potential antitumor activity against CRC, both in vitro and in DMH-induced CRC-modeled animal. In vitro results indicated the high safety of α-LA coated liposomes towards normal human cells with potent antitumor activity against Caco-2 cells at an IC50 value of 57.01 ± 3.55 µM with selectivity index of 6.92 ± 0.48. This antitumor activity has been attributed to induction of the apoptotic mechanism, as demonstrated by nuclear condensation and arrest of Caco-2 cells in sub-G1 populations. α-LA coated liposomes also revealed a significant up-regulation of the p53 gene combined with a down-regulation of the Bcl2 gene. Moreover, in vivo results revealed that treatment of induced-CRC modeled animals with α-LA coated liposomes for six weeks markedly improved the CRC-disorders; this was achieved from the significant reduction in the values of AFP, CEA, CA19.9, TNF-α, IL-1ß, MDA, and NO coupled with remarkable rise in SOD, GPx, GSH, CAT, and CD4+ levels. The histopathological findings asserted the therapeutic potential of α-LA coated liposomes in the treatment of CRC. Therefore, the present results proved the antitumor activity of α-LA coated liposomes against CRC through the restoration of impaired oxidative stress, improved immune response, and reduced inflammation.Communicated by Ramaswamy H.

ABSTRACT

Hepatocellular carcinoma (HCC) is one of the most lethal and prevalent cancers, closely associated with cirrhosis and fibrosis. This study aimed to assess the antitumor activity of oleic acid-liposomes (uncoated liposomes) upon coating with albumin against HCC. The in vitro studies revealed the high safety of the prepared uncoated and albumin-coated liposomes to normal HFB-4 cells (EC100 of 35.57 ± 0.17 and 79.133 ± 2.92 µM, respectively) with significant anticancer activity against HepG-2 cells with IC50 of 56.29 ± 0.91 and 26.74 ± 0.64 µM, respectively. The albumin-coated liposomes revealed superior apoptosis induction potential (80.7%) with significant upregulation of p53 gene expression (>7.0-fold), compared to OA. The in vivo study revealed that the administration of uncoated or albumin-coated liposomes (100 mg/kg) for six weeks markedly retarded the DENA-induced HCC in Wistar albino rates through regulating the liver enzymes, total bilirubin level, pro-inflammatory cytokines, and oxidative stress. Accordingly, the current study supports the in vitro and in vivo chemo-preventive feature of albumin-coated liposomes against HCC through modulation of apoptosis, improvement of the immune response, reduction of inflammation, and restoration of impaired oxidative stress, which is the first reported to the best of our knowledge.

ABSTRACT

Severe acute respiratory syndrome 2019-new coronavirus (SARS-CoV-2) is a major global challenge caused by a pandemic disease, named 'COVID-19' with no effective and selective therapy available so far. COVID-19-associated mortality is directly related to the inability to suppress the viral infection and the uncontrolled inflammatory response. So, we investigated the antiviral efficiency of the nanofabricated and well-characterized lactoferrin-coated zinc nanoparticles (Lf-Zn-NPs) on SARS-CoV-2 replication and entry into host cells. Lf-Zn-NPs showed potent inhibition of the entry of SARS-CoV-2 into the host cells by inhibition of ACE2, the SARS-CoV-2 receptor. This inhibitory activity of Lf-Zn-NPs to target the interaction between the SARS-CoV-2 spike protein and the ACE2 receptor offers potent protection against COVID-19 outbreaks. Moreover, the administration of Lf-Zn-NPs markedly improved lung fibrosis disorders, as supported by histopathological findings and monitored by the significant reduction in the values of CRP, LDH, ferritin, and D-dimer, with a remarkable rise in CD4+, lung SOD, GPx, GSH, and CAT levels. Lf-Zn-NPs revealed therapeutic efficiency against lung fibrosis owing to their anti-inflammatory, antioxidant, and ACE2-inhibiting activities. These findings suggest a promising nanomedicine agent against COVID-19 and its complications, with improved antiviral and immunomodulatory properties as well as a safer mode of action.

ABSTRACT

The goal of the current study was to investigate the hormonal modulatory efficiency of hesperidin, through its regulatory potential of immunological, inflammatory, and/or antioxidant changes in on hyperthyroidism modeled adult female albino rats. Both normal and hyperthyroidism modeled rats (140-160g) were randomly divided into four groups (10 animals each) as follows: 1) healthy animals were daily ingested with saline for six weeks, and served as control group, 2) healthy animals were intraperitoneally injected with hesperidin (50 mg/kg/day) for a similar period, 3) hyperthyroidism-modeled animals without any treatment acted as positive control, and 4) hyperthyroidism-modeled animals were treated intraperitoneally with hesperidin for a similar period. The findings showed that hesperidin significantly modulated hyperthyroidism deteriorations, this was evidenced by a remarkable decline in serum T4, FT4, T3, FT3, TNF-α, IL1ß-, IL4-, IL-6, and IL-10 levels, with a minor increase in TSH and significant raise in CD4+ level. Similarly, valuable improvement was observed in the oxidative status; serum SOD, GPx, CAT, and GSH levels were dramatically enhanced, associated with remarkable drop in MDA and NO levels. Also, hesperidin demonstrated nephro-hepatoprotective and anti-atherogenic potential, this was achieved from the notable reduction in ALAT and ASAT activities as well as urea, creatinine, cholesterol, and triglyceride close to the corresponding values of healthy group. These findings were supported by histological and immunohistochemical ones that showed a notable decrease in the expression of the calcitonin antibody. In conclusion, hesperidin possesses anti-hyperthyroidism, immunoinflammatory regulatory, and antioxidant activities that evidenced from the improvement of physio-architecture of the thyroid gland, reduction of inflammation and restoration of the impaired oxidative stress. This effect might be mechanized through immunological, inflammatory, apoptotic, and/or antioxidant modulatory pathways.

ABSTRACT

Carrion flies play a significant role in forensic entomotoxicology, where they are employed as alternative samples when traditional samples are unavailable. In situations of poisoned death, these toxins disrupt insect development and affect forensic entomology analyses. So, forensic entomotoxicologists must be aware of this impact. The present study aimed to determine the effects of aluminum phosphide (AlP) and cypermethrin (CP) on the biochemical parameters and antioxidant enzymes of the third instar of Chrysomya megacephala maggots. C. megacephala was reared on normal and poisoned rabbit carcasses with aluminum phosphide and cypermethrin. The third larval instar of C. megacephala was studied using by spectrophotometer for detection of total protein, (TP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), total antioxidant capacity (TAC), superoxide dismutase (SOD), glutathione s-transferase (GST), catalase (CAT) and malondialdehyde (MDA). The results indicated to significantly decrease of TP, TAC, SOD, GST and CAT and increase of AST, ALT and MDA in the maggots reared on the poisoned carcasses with AlP or CP compared with control group. In conclusion, the tested insecticides brought about a decrease antioxidant enzyme activity and increase of MDA could be involved in free radicals in C. megacephala larvae leading to oxidative stress by these insecticidal components.

ABSTRACT

One of the most common tumors to cause death worldwide is colon cancer. This study aims to investigate the antitumor potency of Litophyton sp. methanolic extract (LME) against DMH-induced colon cancer in adult male rats. Group (1) normal rats served as the control, group (2) normal rats were ip-injected with LME at a dose of 100 µg/kg/day, group (3) DMH-induced colon cancer animals, and group (4) colon cancer-modeled animals were treated with LME (100 µg/kg/day) for six weeks. The results revealed that injection of LME markedly regenerated the colon cancer pathophysiological disorders; this was monitored from the significant reduction in the values of serum biomarkers (CEA, CA19.9, AFP), cytokines (TNF-α and IL1ß), and biochemical measurements (ALAT, ASAT, urea, creatinine, cholesterol, and triglycerides) matched significant increase of apoptotic biomarkers (CD4+); similarly, colon DNA fragmentation, MDA, and NO levels were down-regulated. In contrast, a remarkable upregulation in colon SOD, GPx, GSH, and CAT levels was noted. Moreover, the colon histopathological architecture showed obvious regenerations. Chromatography of LME resulted in the purification of two polyhydroxylated steroids (1 and 2) with potential cytotoxic activities. LME performed therapeutic potential colon tumorigenesis; therefore, LME may have a promising chemo-preventive feature against colon cancer, probably via enhancement of the apoptosis pathway, improvement of the immune response, reduction of inflammation, or/and restoration of the impaired oxidative stress.

ABSTRACT

This study identifies promising potential of a novel and safer nanocombination of bovine milk lactoperoxidase (LPO) and lactoferrin (LF) to target breast cancer in vitro and in adult female albino rat model. Favorable selective anticancer effects of the prepared nanocombination were observed, in a dose-dependent manner, against both MCF-7 and MDA cell lines, sparing normal HFB-4 cells. The administration of LPO + LFNPs markedly improved the induced-breast cancer disorders, prolonged survival and reduced the values of serum TNF-α, IL1ß, CD4+, ALAT, ASAT, urea, creatinine, cholesterol and triglycerides with remarkable elevation in mammary SOD and GPx activity and GSH level. Moreover, the histopathological findings showed that LPO + LFNPs succeeded in prevention of mammary gland tumorigenesis. Superior efficacy of LPO + LFNPs was observed against pro-inflammatory cytokines through their anti-inflammatory and immunomodulatory properties. The treatment of LPO + LFNPs more significantly modulated the apoptosis and enhanced the expression of cell cycle regulator genes, which demonstrates a successful tumor therapy in vitro and in vivo. Therefore, this study provided evidence that the chemo-preventive feature of LPO + LFNPs may offer a novel alternative therapy for the treatment of breast cancer through enhances apoptosis pathway, improvement of immune response, reduction of inflammation and restoration of the impaired oxidative stress.

ABSTRACT

BACKGROUND: Heart failure (HF) is a major medical, and epidemiological problems with ischemic heart disease (IHD) is the most common cause of HF. We aimed to assess the plasma B-type natriuretic peptide (BNP) levels, serum growth differentiation factor 15 (GDF15), and high-sensitivity troponin I (hsTnI) in HF patients with and without IHD. METHODS: The study included 120 HF patients, categorized into 51 patients with IHD and 69 patients without apparent IHD. Clinical and echocardiographic assessments of the included patients were performed. ELISA assays of plasma BNP and serum GDF15 were done, while serum hsTnI was measured using chemiluminescent immunoassay. RESULTS: There were significantly higher median values of serum levels for GDF15 (pg/mL) and hsTnI (pg/mL) among IHD group (1,630.5 and 141.8, respectively) compared to non-IHD group (895 and 14.3, respectively, p ˂ 0.05 for both), with non-significant differences regarding to the BNP plasma levels (p ˃ 0.05). In the IHD group, significant positive correlations were observed between GDF15 with both BNP (r = 0.655, p = < 0.001) and hsTnI (r = 0.496, p = < 0.001). Serum GDF15 at a cutoff of ≤ 717 pg/mL has the highest specificity [85.51% vs. 50.72% for BNP (at cutoff > 264 pg/mL) and 59.42% for hsTnI]. Additionally, hsTnI at a cutoff of > 45.2 pg/mL has the highest sensitivity (70.59% vs. 68.63% for BNP and 33.33% for GDF15) in discriminating heart failure with IHD from heart failure without IHD. CONCLUSIONS: A multimarker approach, particularly GDF15 and hsTnI, is helpful in identifying HF patients with underlying IHD, thus enabling their proper management.

ABSTRACT

<b>Background and Objective:</b> The use of Doxorubicin<sup>®</sup> (Doxo) in the treatment of different tumours is restricted due to its cardiotoxicity. The objective of this study was to determine the protective effect of<i> Balanites aegyptiaca</i> extract against cardiotoxicity induced by Doxorubicin<sup>®</sup> in male rats. <b>Materials and Methods:</b> Adult male rats (140-160) were parted into 6 groups (10 animals each) as follows: Group (1) Normal rats the control, group (2) Rats were administered BAE (200 mg kg<sup>1</sup>) orally for 4 weeks, group (3) Rats were treated IP with the anticancer drug (Doxorubicin<sup>®</sup>) at the dose of (0.5 mg kg<sup>1</sup>) for 4 weeks, group (4) Administrated orally with BAE in combination with Doxo injection for 4 weeks, group (5) Rats orally with BAE before intoxication with Doxo for 4 weeks and finally group (6) Animals post-administration of BAE for 4 weeks after intoxication with Doxo. After 4 weeks of injections. <b>Results:</b> Revealed that BAE succeeded to decline the Doxorubicin cardiotoxicity, this was evidenced by the significant reduction of serum LDH, CK-MB, total cholesterol, triglycerides, HDL, TNF-α, IL-1ß and IL-6 as well as cardiac MDA and nitric oxide levels coupled with marked improvement in serum LDL, PON1 as well as cardiac GSH, SOD and CAT. Moreover, the BAE induced prominent regeneration of the cardiac muscle. <b>Conclusion:</b> <i>Balanites aegyptiaca</i> extract may be a promising cardio-protector against Doxorubicin<sup>®</sup> toxicity mediated through their antioxidant and radical scavenging activities.

ABSTRACT

<b>Background and Objective:</b> Oxaliplatin<sup>®</sup> is an antineoplastic platinum-based compound; nephrotoxicity is one of its most serious side effects. This study aimed to explore the nephroprotective potential of Costus Ethanolic Extract (CEE) against Oxaliplatin<sup>®</sup>-induced nephrotoxicity. <b>Materials and Methods:</b> Adult male Wistar rats, weighting 140-160 g, were randomly divided into four groups: (1) Normal rats, (2) Rats ingested with CEE (67.08 mg kg<sup>1</sup> day<sup>1</sup>), (3) Rats injected (ip) with Oxaliplatin<sup>®</sup> (10 mg kg<sup>1</sup> week<sup>1</sup>) and (4) rats treated with CEE in combination Oxaliplatin<sup>®</sup> injection. <b>Results:</b> After six weeks of treatments, the results revealed that CEE ingestion along with Oxaliplatin<sup>®</sup> injection markedly minimized the Oxaliplatin<sup>®</sup>-induced renal deterioration; this was evidenced by the significant reduction in serum urea, creatinine, uric acid, Tumor Necrosis Factor Alpha (TNF-α), Interleukin 1Beta (IL<sup>1</sup>ß) and Sodium ion (Na<sup>+</sup>) levels as well as kidney Malondialdehyde (MDA), Nitric Oxide (NO) and DNA fragmentation values. Controversially, a marked rise in serum Calcium, Potassium Ion (K<sup>+</sup>) and Cluster of Differentiation 4 (CD4) levels besides renal Glutathione (GSH), Catalase (CAT) and Superoxide Dismutase (SOD) values. Similarly, the histopathological findings confirmed the biochemical ones as the CEE restored the Oxaliplatin<sup>®</sup>-induced histological degenerations. <b>Conclusion:</b> In conclusion, CEE exhibited nephron-protection efficiency against Oxaliplatin<sup>®</sup>-induced nephrotoxicity; this promising effect may be achieved through the antioxidant and radical scavenging activities of its constituents.

ABSTRACT

BACKGROUND AND OBJECTIVE: Pyrethroidsare a group of synthetic pesticides similar to the natural pesticide pyrethrum, which is produced by chrysanthemum flowers. Bifenthrin is one of the pyrethroids that are widely used pesticide in households and to control crop vectors. The main goal of this work was to investigate the possible ameliorating effect of Costus Ethanolic Extract (CEE) against neurotoxicity induced by bifenthrin in adult-male rats. MATERIALS AND METHODS: Rats were arranged randomly to 4 groups (8 rats each) as next. Group 1) control rats orally received 0.5 mL water for consecutive 30 days; group 2) healthy rats orally received CEE (200 mg kg) for consecutive thirty days; group 3) rats treated orally with 7 mg kg-1 day-1 bifenthrin for consecutive 30 days and group 4) included rats treated with bifenthrin for consecutive 30 days followed by administration with CEE another consecutive 30 days. RESULTS: The results showed that CEE succeeded to decline the neurotoxicity-induced by bifenthrin; this was evidenced by the significant reduction in TNF-α, IL- 1ß, MDA and nitric oxide levels in cortex, hippocampus and striatum concomitant with marked improvement in the values of GSH, dopamine, serotonin, AChE-ase, SOD, GPx and catalase that were diminished by bifenthrin intoxication. CEE improved also cognitive impairment and the deficits in motor coordination induced by bifenthrin. CONCLUSION: CEE was found successful, to a great extent, to counteract the bifenthrin-induced brain oxidative stress and neurochemical deteriorations and possesses a protective potential against brain-induced neurotoxicity. Therefore, it may be a promising supplement for the amelioration of BF-neurotoxicity.

ABSTRACT

Cardiovascular complications in ST-segment-elevation myocardial infarction survivors remain substantial despite advances in the management of STEMI. We aimed to determine effect of AH on the area at risk (AAR), final infarct size (FIS), and salvage index (SI) in STEMI patients using cardiac magnetic resonance (CMR). 43 successfully reperfused STEMI patients were recruited. CMR was utilized to estimate AAR and FIS, SI was calculated: SI = AAR- FIS/AAR. AH showed significant positive correlations to FIS (r-value = 0.538, P = < 0.001), and AAR (r-value = 0.435, P = 0.002), and a negative correlation with SI (r-value = -0.378, P = 0.006).

ABSTRACT

BACKGROUND AND OBJECTIVE: The addition of fine-needle aspiration (FNA) to different imaging modalities has raised the accuracy for diagnosis of cystic pancreatic lesions. We aim to differentiate benign from neoplastic pancreatic cysts by evaluating cyst fluid carcinoembryonic antigen (CEA), carbohydrate antigen (CA19-9), and amylase levels and cytopathological examination, including mucin stain. PATIENTS AND METHODS: This prospective study included 77 patients with pancreatic cystic lesions. Ultrasound-FNA (US-FNA) or endoscopic ultrasound-FNA (EUS-FNA) was done according to the accessibility of the lesion. The aspirated specimens were subjected to cytopathological examination (including mucin staining), tumor markers (CEA, CA19-9), and amylase level. RESULTS: Cyst CEA value of 279 or more showed high statistical significance in differentiating mucinous from nonmucinous lesions with sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of 73%, 60%, 50%, 80%, and 65%, respectively. Cyst amylase could differentiate between neoplastic and nonneoplastic cysts at a level of 1043 with sensitivity of 58%, specificity of 75%, PPV of 73%, NPV of 60%, and accuracy of 66%. CA19-9 could not differentiate between neoplastic and nonneoplastic cysts. Mucin examination showed a sensitivity of 85%, specificity of 95%, PPV of 92%, NPV of 91%, and accuracy of 91% in differentiating mucinous from non-mucinous lesions. Cytopathological examination showed a sensitivity of 81%, specificity of 94%, PPV of 94%, NPV of 83%, and accuracy of 88%. CONCLUSION: US or EUS-FNA with analysis of cyst CEA level, CA19-9, amylase, mucin stain, and cytopathological examination increases the diagnostic accuracy of cystic pancreatic lesions.
