Abstract
AbstractThe 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
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
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-1β, 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
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
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
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, IL1β-, 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
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, IL1β, 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: Testicular dysfunction is one of the common side effects that results from the treatment with oxaliplatin® as a chemotherapy drug, and pharmaceutical search for agents to relieve the side effects are underway. The current study explored the possible ameliorative and regenerative effects of Costus ethanolic extract against testicular degeneration in male rats induced by oxaliplatin. Methods: Male Wistar albino rats weighing 150-200g were divided into four groups of 10 rats each as follows: group-1 control rats; group-2 rats treated orally with the extract at 50 mg/kg/day for six weeks; group-3 rats injected oxaliplatin intraperitoneally at 10 mg/kg/week for six successive weeks; group-4 rats were injected intraperitoneally with oxaliplatin at 10 mg/kg/week combined with a daily oral dose of the Costus extract for six weeks. Results: Data from the current study revealed that the extract lowered the toxic effect of oxaliplatin on the testicular tissue samples. This was evident by the significant rise in the serum of total & free testosterone and CD4 cells, and the levels of GSH, SOD and CAT activities in the testis coupled with a marked reduction of serum TNF-α and IL-1β and testis MDA, nitric oxide levels and DNA fragmentation. Also, the extract promoted the regeneration of the histopathological structure of the testis. Conclusion: This study proposes a novel therapeutic application for the Costus extract as a therapeutic agent against testicular toxicity induced by oxaliplatin treatment through its promising anti-inflammatory and antioxidant properties.

Abstract
Gonadotrophins play key roles in follicular development; however, the underlying molecular mechanisms are not fully understood. Follicle stimulating hormone (FSH) regulation of aromatase and subsequent estradiol (E2) production relies on β-catenin, a key effector of WNT signaling. We previously demonstrated that treatment with the canonical WNT inhibitor, IWR-1, reduced FSH induced bovine granulosa cell E2 production in vitro. Here we demonstrated that intrafollicular injection in vivo with IWR-1 alters steroidogenesis and triggers a significant decrease in estrogen to progesterone ratio in the IWR-1 treated follicles compared to diluent injected control follicles. We next examined markers of canonical and noncanonical WNT signaling in dominant and subordinate follicles collected at different stages of follicular development and showed that protein for both CTNNB1 (canonical pathway) and phosphorylated (p)-LEF1 (noncanonical pathway) was significantly elevated in dominant compared to subordinate follicles at the early dominance stage of development. Therefore, we hypothesized that canonical and/or noncanonical WNT ligands modulate FSH stimulated E2 production. Hence, we examined the effects of specific WNT ligands on FSH stimulated E2 production in the absence of endogenous WNT production in vitro. Universal WNT signaling inhibitor, LGK-974 was able to inhibit FSH stimulation of E2 and reduce the abundance of proteins linked to canonical and noncanonical WNT pathway activation. Supplementation with the canonical ligand WNT2b did not affect the inhibitory effects of LGK-974 on FSH stimulated E2 production but rescued the LGK-974 mediated inhibition of CTNNB1 (canonical pathway) but not p-LEF1, p-JNK or p-P38 abundance (noncanonical pathway) abundance. In contrast, WNT5a treatment rescued FSH stimulated estradiol production and indices of activation of both the canonical (CTNNB1) and noncanonical (p-LEF1, p-JNK and p-P38) WNT signaling pathways in LGK-974 treated granulosa cells. Taken together, these results suggest that both canonical and noncanonical WNT pathways activation is linked to FSH stimulation of E2 production by bovine granulosa cells.

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>β) 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- 1β, 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
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.

Abstract
Embryo transfer remains a viable approach to increase propagation of offspring from high genetic merit females. Although it is now over 60 years since the report of the birth of the first calf from embryo transfer, utilisation of embryo transfer technology worldwide is not widespread. Limitations of conventional procedures for superovulation and embryo transfer are not limited to but include variability in response to superovulation, the labour intensive nature of superovulation procedures, time required between collections and cost of technology. Recently, harvest of ova and transfer of in vitro produced embryos has received more attention as a potential alternative to conventional superovulation and subsequent embryo transfer. Aspiration of follicular ova and in vitro embryo production offers potential advantages in reducing loss of female germplasm occurring through the natural process of ovarian follicular atresia, can increase yield of embryos from elite donor cows beyond that possible with superovulation, and provides a means of salvaging genetic material from valuable animals at slaughter or those culled for disease control or other reasons. Recent evidence indicates poor ovum quality is a major factor limiting in vitro embryo production and discovery of a role for intrinsic factors such as ovum follistatin and cumulus cell cathepsins in control of ovum quality has led to ongoing research on new technologies to increase yield of transferable embryos.

Abstract
Coronary artery aneurysms are usually diagnosed by contrast coronary angiography, which portrays the silhouette of the lumen but cannot distinguish true and false aneurysms. To differentiate true and false aneurysms and to study the morphologic changes of the vessel wall, intravascular ultrasound (IVUS) was performed in patients with angiographic signs of coronary artery aneurysms. We used a 4.8F or 3.5F, 20 MHz IVUS catheter for ultrasound examination. Fourteen patients (12 men and two women ranging in age from 43 to 73 years) with angiographic signs of coronary aneurysm were enrolled. IVUS imaging was optimally obtained in all patients. The vessel area, lumen area, and plaque area of the aneurysm segment and of the proximal and distal segments were determined. IVUS showed that both the proximal and distal reference segments were severely affected by atherosclerotic lesions in all the patients and by calcium deposits in six patients. The percent stenoses were 63.0% +/- 13.7% and 60.9% +/- 17.8% in the proximal and distal reference segments, respectively. In nine patients the walls of the aneurysms showed signs of atherosclerosis. Three angiographically indicated aneurysms were found to be plaque ruptures. Although the lumen and the vessel areas of the aneurysm segments were larger than those of the proximal and distal segments (p < 0.01 and (p < 0.001), no significant differences in plaque area and plaque composition were found between the aneurysm segment and adjacent vessel segments (p > 0.05). In conclusion, IVUS allows detailed characterization of coronary aneurysms. Atherosclerosis seems to play an important role in the formation of acquired coronary aneurysms.
