Abstract
The healthcare systems of African nations heavily rely on importing and repackaging biological medicine. More than 70% of the pharmaceutical products consumed in Africa are imported. The localization of biosimilar production can have a positive impact on the availability and cost of these products by reducing the expenses for African governments and making essential healthcare products more accessible to the population. However, it is evident that the developing countries, particularly African nations, face various obstacles and difficulties in localizing biosimilar production. These challenges encompass development, manufacturing, evaluation, and registration processes. In this review, we will highlight the significant hurdles and achievements encountered during the localization process of biosimilars.

Abstract
Benign prostatic hyperplasia (BPH) poses a significant health concern amongst elderly males. Canagliflozin (Cana), a selective sodium-glucose co-transporter 2 (SGLT2) inhibitor, has a powerful anti-inflammatory influence. Nevertheless, its role in treating BPH has not been clarified. Therefore, the study aimed to investigate the potential ameliorative effect of Cana on experimentally induced BPH in rats and explore the underlying mechanisms compared to the standard finasteride (Fin). The study employed histological analysis, biochemical assays using ELISA, and western blotting. Animals were categorized into four groups: Control (2.5 ml/kg CMC, orally + 3 ml/kg olive oil, subcutaneous), BPH (3 mg/kg testosterone, subcutaneous + CMC orally), Fin-treated BPH (5 mg/kg, orally), and Cana-treated BPH (5 mg/kg, orally), for 28 days. The BPH group showed obvious BPH manifestations including an increase in prostate weight (PW), prostate index (PI), dihydrotestosterone (DHT) level, and histological aberrations compared to control. Fin and Cana therapy had a comparable impact. Cana treatment significantly reduced PW and PI, besides it improved prostatic biochemical, and histopathological features compared to BPH, consistent with in silico study findings. Cana was associated with downregulation of the androgen axis, increased miR-128b expression, with a lowered expression of epidermal growth factor (EGF) and its receptor. Phosphorylation of STAT3 and its downstream proliferative markers were significantly reduced suggesting apoptotic activity. Cana markedly rescued the BPH-induced upregulation of IL-1β, and iNOS levels. Altogether, the current study demonstrates that Cana could impede BPH progression, possibly by modulating miR-128b/EGFR/EGF and JAK2/STAT3 pathways and downregulating AR, cyclin D1, and PCNA immunoreactivity.

Abstract
Meloxicam has shown significant neuroprotection in experimental models of stroke, Alzheimer's disease, and Parkinson's disease. However, the potential of meloxicam to treat depression-like neuropathology in a chronic restraint stress (CRS) model and the associated molecular changes has been insufficiently explored. The current work aimed to explore the potential neuroprotective actions of meloxicam against CRS-evoked depression in rats. In the current experiments, animals received meloxicam (10 mg/kg/day; i.p.) for 21 days, and CRS was instigated by restraining the animals for 6 h/day during the same period. The sucrose preference test and the forced swimming test were used to explore the depression-linked anhedonia/despair, whereas the open-field test examined the animals' locomotor activity. The current findings revealed that CRS elicited typical depression behavioral anomalies in the animals, including anhedonia, despair, and diminished locomotor activity; these findings were reinforced with Z-normalization scores. These observations were corroborated by brain histopathological changes and increased damage scores. In CRS-exposed animals, serum corticosterone spiked, and the hippocampi revealed decreased monoamine neurotransmitter levels (norepinephrine, serotonin, and dopamine). Mechanistically, neuroinflammation was evident in stressed animals, as shown by elevated hippocampal TNF-α and IL-1β cytokines. Moreover, the hippocampal COX-2/PGE2 axis was activated in the rats, confirming the escalation of neuroinflammatory events. In tandem, the pro-oxidant milieu was augmented, as seen by increased hippocampal 8-hydroxy-2'-deoxyguanosine alongside increased protein expression of the pro-oxidants NOX1 and NOX4 in the hippocampi of stressed animals. In addition, the antioxidant/cytoprotective Nrf2/HO-1 cascade was dampened, as evidenced by the lowered hippocampal protein expression of Nrf2 and HO-1 signals. Interestingly, meloxicam administration mitigated depression manifestations and brain histopathological anomalies in the rats. These beneficial effects were elicited by meloxicam's ability to counteract the corticosterone spike and hippocampal neurotransmitter decrease while also inhibiting COX-2/NOX1/NOX4 axis and stimulating Nrf2/HO-1 antioxidant pathway. Together, the present findings prove the neuroprotective/antidepressant actions of meloxicam in CRS-induced depression by ameliorating hippocampal neuroinflammation and pro-oxidant changes, likely by modulating COX-2/NOX1/NOX4/Nrf2 axis.

Abstract
Doxorubicin (DOX) is one of the basic anticancer drugs, nonetheless its use is restricted due to noxious side effects. Kidney failure is one of the main side effects that restrict its medical use. The current study assessed the nephroprotective effects of fenofibrate and pioglitazone against the renal injury induced by doxorubicin in rats and illustrated the probable mechanisms underlying these protective effects. For this purpose, Male Sprague-Dawley rats weighing (200-230 g) were allocated into seven groups treated for 15 days as following: control (50% corn oil + 50% DMSO p.o), fenofibrate (100 mg/kg p.o) and pioglitazone (10 mg/kg p.o) as well as four groups of DOX (15 mg/kg i.p on 11th day). DOX groups included DOX alone and DOX with protective drugs fenofibrate, pioglitazone or both of them. As a result of doxorubicin nephrotoxicity; serum creatinine and blood urea nitrogen were remarkably elevated. Moreover, renal glutathione was significantly reduced while tissue lipid peroxidation malondialdehyde, tumor necrosis factor-α, nuclear factor-kappa B p65 (NF-κB p65), interleukin-1β, p38 mitogen activated protein kinase (p38-MAPK) and caspase-3 (Casp-3) were significantly augmented. Treatment with fenofibrate and pioglitazone either alone or in combination markedly attenuated DOX-induced injury by suppression of oxidative stress, inflammation and apoptosis. The above-mentioned biochemical markers were affirmed by histological assessment. In conclusion, fenofibrate, pioglitazone, and their combination possess potential prophylactic effects against doxorubicin-induced renal injury through modulation of p38-MAPK/NF-κB p65 pathway with superiority to the combination.

Abstract
Exposure to Lead -causes testicular dysfunction through oxidative stress, inflammation, and apoptosis; however, naringenin (NGN) therapeutic impact against lead-evoked testicular dysfunction remains elusive. Herein, the point of the study was to examine the defensive impact of NGN on testicular dysfunction initiated by lead. Seventy-Two male Wistar rats were allotted into nine groups; control group, drug control groups, lead acetate group, as well as NGN treated groups (10, 25, and 50 mg/kg) respectively, given 5 days before lead acetate treatment. The result showed clearly the impact of lead on reduced sperm count, sperm motility as well as serum testosterone and LH levels. Additionally, it caused a significant rise in testicular inflammatory markers TNF-α, IL-1β, and TGFβ, effects that were accompanied by a reduction of AKT and mTOR levels. Lead acetate also caused degenerative changes in the testis, atrophy, and loss of spermatogenic series. Our findings revealed that NGN in a dose-dependent manner improved spermiotoxicity induced by lead acetate via restoration of the testicular function, preservation of spermatogenesis, halting inflammatory cytokines along with the enhancement of germ cell survival using upregulation of AKT/mTOR expressions. The present study discloses that NGN suppresses lead acetate toxicity that is involved in the antioxidant effect in a dose-dependent manner, besides its anti-inflammatory property.

Abstract
Magnesium sulfate has demonstrated marked neuroprotection in eclampsia, hypoxia, stroke, and post-traumatic brain injury rodent models. However, its potential impact against chronic-restraint-stress (CRS)-induced depression-like neuropathology and associated alterations in endoplasmic reticulum (ER) stress have not been adequately examined. The present study aimed to investigate the neuroprotective potential of magnesium sulfate in a rat model of CRS-triggered depression-like behavioral disturbance and the underlying molecular mechanisms. Herein, CRS was induced by placing rats into restraining tubes for 6 h/day for 21 days and the animals were intraperitoneally injected with magnesium sulfate (100 mg/kg/day) during the study period. After stress cessation, the depression-like behavior was examined by the open-field test, sucrose preference test, and forced swimming test. The present data demonstrated that CRS triggered typical depression-like behavioral changes which were confirmed by the Z-normalization scores. Mechanistically, serum circulating corticosterone levels spiked, and the hippocampi of CRS-exposed animals demonstrated a significant decline in serotonin, norepinephrine, and dopamine neurotransmitters. At the molecular level, the hippocampal pro-inflammatory TNF-alpha and IL-1β cytokines and the oxidative stress marker 8-hydroxy-2'-deoxyguanosine (8-HG) increased in stressed animals. In tandem, enhancement of hippocampal ER stress was evidenced by the activation of iNOS/PERK/GRP78/CHOP axis seen by increased protein expression of iNOS, PERK, GRP78, and CHOP signal proteins in the hippocampi of stressed rats. Interestingly, magnesium sulfate administration attenuated the depression-like behavioral outcomes and the histopathological changes in the brain hippocampi. These favorable actions were driven by magnesium sulfate's counteraction of corticosterone spike, and hippocampal neurotransmitter decline, alongside the attenuation of neuroinflammation, pro-oxidation, and ER stress. In conclusion, the current results suggest the promising neuroprotective/antidepressant actions of magnesium sulfate in CRS by dampening inflammation, ER stress, and the associated PERK/GRP78/CHOP pathway.

Abstract
Abstract
Doxorubicin (DOX) is one of the basic chemotherapeutic drugs for cancer treatment, but its use is restricted due to noxious side effects. One of the major side effects that restrict its medical use is kidney failure. The PPAR-α agonists have been displayed to have beneficial effects against drug-induced nephropathy in animals. Similarly, PPAR-γ agonists have revealed nephroprotection by haemodynamic, vascular, anti-inflammatory, anti-oxidant and metabolic effects. This study examined the nephroprotective effects of fenofibrate (FENO) and pioglitazone (PIO) against the nephrotoxicity induced by doxorubicin in rats and illustrate the probable mechanisms underlying these protective effects. For this purpose, Male Sprague-Dawley rats weighing (200 to 230 g) were allocated into seven groups treated for 15 days as following: control (50% corn oil + 50% DMSO p.o), fenofibrate (100 mg/kg p.o) and pioglitazone (10 mg/kg p.o) as well as four groups of DOX (15 mg/kg i.p on 11th day). DOX groups included DOX alone and DOX with protective drugs fenofibrate, pioglitazone or both of them. As a result of doxorubicin nephrotoxicity; serum creatinine and blood urea nitrogen (BUN) were significantly elevated. Moreover, renal glutathione (GSH) was significantly reduced while tissue lipid peroxidation malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), nuclear factor-kappa B p65 (NF-κB p65), interleukin-1β (IL-1β), p38 mitogen activated protein kinase (p38-MAPK) and caspase-3 (Casp-3) were significantly increased. Administration of fenofibrate and pioglitazone either alone or in combination significantly attenuated DOX-induced injury by suppression of oxidative stress, inflammation and apoptosis. The above-mentioned biochemical markers were affirmed by histological assessment. In conclusion, Fenofibrate, pioglitazone and their combination possess promising protective effects against doxorubicin-induced nephrotoxicity through modulation of p38-MAPK/ NF-κB p65 pathway with superiority to the combination.

Abstract
Polydatin (PD) is a polyphenolic compound found naturally in many fruits such as grapes. It has anti-oxidant and anti-inflammatory activities that are of paramount importance for its pharmacological actions. This study aimed to explore possible protective effects of PD against methotrexate (MTX)-induced pulmonary fibrosis in rats. A single oral dose of MTX (14 mg/kg) per week for 2 weeks caused a significant decrease in glutathione (GSH) content with a marked increase in transforming growth factor-beta (TGF-β), alpha-smooth muscle actin (α-SMA), pulmonary content of malondialdehyde (MDA), interleukin-1β (IL-1β), Hydroxyproline, tumor necrosis factor-alpha (TNF-α), and 8-hydroxy-2'-deoxyguanosine (8-OHdG) as compared with the control group. Contrarily, daily administration of PD (25, 50, and 100 mg/kg, p.o.) for 14 days concomitantly with MTX ameliorated MTX-induced pulmonary fibrosis as indicated by mitigation of the previously mentioned biochemical parameters and histopathological changes in a dose-dependent manner. In conclusion, the protective effect of PD against pulmonary fibrosis induced by MTX in rats might be attributed to its anti-oxidant, anti-inflammatory as well as anti-fibrotic effects.

Abstract
Depression is a widespread, withering illness, resulting in a massive personal suffering and economic loss. The chronic exposure to stress may be involved in the etiology of human psychiatric disorders; such as depression. In the current study, the animals were subjected to chronic unpredictable mild stress (CUMS) for 14 days. Saxagliptin (SAXA) is a member of dipeptidyl peptidase-4 (DPP-4) inhibitors class. The current study was the first one to examine the anti-depressive effect of SAXA in an experimental model of CUMS-induced depression in rats and the possible underlying mechanisms. Animals were orally treated with SAXA (0.5, 1 and 2 mg/kg) for 14 days. SAXA treatment reversed the CUMS-induced alterations in the behavioral, biochemical as well as histopathological parameters. Moreover, it hindered the CUMS-induced increase in the oxidative stress, inflammatory, and apoptotic markers. On the other hand, it increased the monoamines levels and the neurogenic brain derived neurotrophic factor (BDNF). In addition, SAXA treatment increased the incretin hormones, glucagon like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP), which are linked to the activation of protein kinase B (AKT)/phosphatidylinositol3-kinase (PI3K) pathway. In conclusion, the current study revealed that the modulation of the interplay between the key events involved in depression, including oxidative stress, inflammation, and GLP-1/PI3K/AKT signaling pathway, can explain the anti-depressant activity of SAXA.

Abstract
AIMS Saxagliptin, a selective/potent dipeptidyl peptidase-4 inhibitor, has revealed remarkable anti-inflammatory features in murine models of nephrotoxicity, hepatic injury, and neuroinflammation. However, its potential effect on ethanol-induced gastric mucosal injury has not been examined. Hence, the present work investigated the prospect of saxagliptin to attenuate ethanol-evoked gastric injury, with emphasis on the AMPK/mTOR-driven autophagy and NLRP3/ASC/caspase-1 pathway. MATERIALS AND METHODS In ethanol-induced gastropathy, the gastric tissues were examined by immunohistochemistry, immunoblotting, histopathology, and ELISA. KEY FINDINGS The results demonstrated that saxagliptin (10 mg/kg; by gavage) suppressed the gastric pathological signs (area of gastric ulcer and ulcer index scores), histopathologic aberrations/damage scores, without provoking hypoglycemia in rats. These protective features were attributed to the enhancement of gastric mucosal autophagy flux, as proven with increased expression of LC3-II and Beclin 1, decreased accumulation of p62 SQSTM1, and activation of the autophagy-linked AMPK/mTOR pathway by increasing the expression of p-AMPK/AMPK and decreasing the expression of the autophagy suppressor p-mTOR/mTOR signal. In tandem, saxagliptin counteracted the ethanol-induced pro-apoptotic events by downregulating Bax, upregulating Bcl2 protein, and lowering the Bax/Bcl2 ratio. Equally important, saxagliptin suppressed the NLRP3 inflammasome in the gastric tissue by lowering the expression of NLRP3, ASC, and nuclear NF-κBp65, decreasing the activity of caspase-1, and diminishing the IL-1β levels. In the same regard, saxagliptin suppressed the mucosal oxidative stress by lowering lipid peroxide levels, increasing GSH and GPx antioxidants, and activating Nrf2/HO-1 pathway. SIGNIFICANCE Saxagliptin may be a promising intervention against ethanol-evoked gastropathy by activating AMPK/mTOR-driven autophagy and inhibiting NLRP3 inflammasome.

Abstract
Doxorubicin (DOX) is a potent chemotherapeutic agent widely used for the treatment of several malignancies. Despite its effectiveness, DOX has been implicated in induced neurotoxicity manifested as cognitive dysfunction with varying degrees, commonly referred to as chemobrain. DOX-induced chemobrain is presumed to be due to cytokine-induced inflammatory, oxidative, and apoptotic responses damaging the brain. Atorvastatin (ATV), 3-hydroxy 3-methylglutaryl co-enzyme A (HMG Co-A) reductase inhibitor, is a cholesterol-lowering statin possessing beneficial pleiotropic effects, including anti-inflammatory, antioxidant, and anti-apoptotic properties. Therefore, this study aims to investigate the potential neuroprotective effects of ATV against DOX-induced cognitive impairment studying the possible involvement of heme oxygenase-1 (HO-1) and endoplasmic reticulum (ER) stress biomarkers. Rats were treated with DOX (2 mg/kg/week), i.p. for 4 weeks. Oral treatment with ATV (10 mg/kg) ameliorated DOX-induced behavioral alterations, protected brain histological features, and attenuated DOX-induced inflammatory, oxidative, and apoptotic biomarkers. In addition, ATV upregulated the protective HO-1 expression levels and downregulated the DOX-induced apoptotic ER stress biomarkers. In conclusion, ATV (10 mg/kg) exhibited neuroprotective properties against DOX-induced cognitive impairment which could possibly be attributed to their anti-inflammatory, antioxidant, and anti-apoptotic effects in the brain.

Abstract
Cyclosporine (CsA) is a widely used immunosuppressive agent that incurs marked nephrotoxicity in the clinical setting. Thus, there is a need for finding safe/effective agents that can attenuate CsA-induced kidney injury. Meanwhile, the underlying mechanisms for CsA-associated nephrotoxicity are inadequately investigated, in particular, the AKT/eNOS/NO pathway. Here, the present work aimed to explore the potential of camel milk, a natural product with distinguished antioxidant/anti-inflammatory actions, to ameliorate CsA-induced nephrotoxicity in rats. The molecular mechanisms related to renal oxidative aberrations and apoptosis were studied, including Nrf2/HO-1 and AKT/eNOS/NO pathways. The kidney tissues were inspected using histopathology, ELISA, Western blotting, and immunohistochemistry. The present findings demonstrated that camel milk (10 ml/kg) significantly lowered creatine, BUN, and NGAL nephrotoxicity markers and the aberrant histopathology, with similar efficacy to the reference quercetin. Moreover, camel milk suppressed the renal oxidative stress, as evidenced by significantly lowering NOX-1 and lipid peroxides and significantly augmenting the renal antioxidant moieties (GSH, GPx, and SOD), thereby, driving the restoration of Nrf2/HO-1 pathway. Meanwhile, camel milk counteracted the pro-apoptotic reactions by significantly lowering Bax protein expression, caspase-3 activity/cleavage, and PARP cleavage, alongside significantly increasing the expression of the proliferation signal PCNA. Regarding the anti-apoptotic AKT/eNOS/NO pathway, camel milk activated its signaling by significantly increasing the protein expression of PI3Kp110, p-AKT(Ser473)/total AKT, and p-eNOS (Ser1177)/total eNOS besides significantly boosting the renoprotective NO levels. In conclusion, these findings reveal that camel milk may be a promising candidate for the alleviation of CsA-induced nephrotoxicity.

Abstract
Paracetamol is a commonly used over-the-counter analgesic and antipyretic drug. Nevertheless, an overdose of paracetamol leads to hepatic necrosis that can be lethal. This study aimed to assess the potential hepatoprotective effects of dibenzazepine, a Notch inhibitor, against acute liver injury in rats via interfering with oxidative stress, inflammation, apoptosis, autophagy, and Notch signaling. Silymarin (200 mg/kg, p.o.) or dibenzazepine (2 mg/kg, i.p.) were administered to rats for 5 days before a single hepatotoxic dose of paracetamol (800 mg/kg, i.p.). Pretreatment with silymarin and dibenzazepine significantly mitigated oxidative stress, inflammatory and apoptotic markers induced by paracetamol hepatotoxicity where dibenzazepine showed greater repression of inflammation. Furthermore, dibenzazepine was found to be significantly more efficacious than silymarin in inhibiting Notch signaling as represented by expression of Notch-1 and Hes-1. A significantly greater response was also demonstrated with dibenzazepine pretreatment with regard to the expression of autophagic proteins, Beclin-1 and LC-3. The aforementioned biochemical results were confirmed by histopathological examination. Autophagy and Notch signaling seem to play a significant role in protection provided by dibenzazepine for paracetamol-induced hepatotoxicity in rats, which could explain its superior results relative to silymarin.

Abstract
AIMS Cadmium (Cd) is a prevalent environmental contaminant that incurs deleterious health effects, including testicular impairment. Sitagliptin, a selective dipeptidyl peptidase-4 (DPP-4) inhibitor, has demonstrated marked cardio-, hepato-, and reno-protective actions, however, its impact on Cd-triggered testicular dysfunction has not been formerly investigated. Hence, the present study aimed to explore the probable beneficial impact of sitagliptin against Cd-evoked testicular impairment which may add to its potential clinical utility. The underlying mechanisms pertaining to the balance between testicular autophagy and apoptosis were explored, including the AMPK/mTOR and Nrf2/HO-1 pathways. MATERIALS AND METHODS The testicular tissues were examined using histopathology, immunohistochemistry, Western blotting, and ELISA. Sitagliptin (10 mg/kg/day, by gavage) was administered for 4 consecutive weeks. KEY FINDINGS Sitagliptin attenuated the testicular impairment via improvement of the relative testicular weight, sperm count/motility, sperm abnormalities, and serum testosterone. Additionally, sitagliptin counteracted Cd-induced histologic aberrations/disrupted spermatogenesis. Interestingly, sitagliptin augmented the defective autophagy as demonstrated by upregulating Beclin 1 protein expression and lowering p62 SQSTM1 protein accumulation. These effects were mediated via the activation of testicular AMPK/mTOR pathway as proven by increasing p-AMPK (Ser485, Ser491)/total AMPK and diminishing p-mTOR (Ser2448)/total mTOR protein expression. Additionally, sitagliptin suppressed the testicular apoptotic events via downregulating Bax and upregulating Bcl-2 protein expression. In tandem, sitagliptin suppressed the oxidative stress through lowering lipid peroxides and activating Nrf2/HO-1 pathway via upregulating the protein expression of Nrf2, and the downstream effectors HO-1 and GPx. SIGNIFICANCE Sitagliptin attenuated Cd-induced testicular injury via boosting the autophagy/apoptosis ratio through activation of AMPK/mTOR and Nrf2/HO-1 pathways.

Abstract
Cisplatin is one of the standard anti-cancer agents that are used to treat variety of solid tumors. Nevertheless, due to the accumulation of cisplatin in the renal epithelial cells, nephrotoxicity was found to be the main side effect that limits its clinical use. The current study was conducted to assess the potential nephroprotective effect of dibenzazepine, a Notch inhibitor, against cisplatin-induced nephrotoxicity in rats as well as the possible mechanisms underlying this nephroprotection. The rats were pre-treated with 2 mg/kg dibenzazepine for 7 days before giving a single nephrotoxic dose of cisplatin (7 mg/kg). Cisplatin induced acute nephrotoxicity, where blood urea nitrogen and serum creatinine levels were significantly increased. Besides, lipid peroxidation was markedly elevated and the levels of reduced glutathione and catalase were significantly reduced. Also, the tissue levels of the pro-inflammatory mediators; IL-1β, TNF-α, and NF-kB, were significantly increased in the cisplatin group. The pre-treatment with dibenzazepine significantly mitigated the nephrotoxic effects of cisplatin, the oxidative stress and inflammatory status as well as decreased caspase-3 expression, as compared to the cisplatin group. Furthermore, the up-regulation of Notch-1 and Hes-1 was found to be involved in cisplatin-induced nephrotoxicity and their expression was significantly reduced by dibenzazepine. The nephroprotective effect of dibenzazepine was further confirmed by the histopathological assessment. Moreover, dibenzazepine pre-treatment of hela and PC3 cells in vitro did not antagonize the cisplatin anti-cancer activity. In conclusion, these findings show that dibenzazepine provides protection against cisplatin-induced nephrotoxicity. Moreover, the up-regulation of the Notch pathway was shown to play a role in the pathogenesis of cisplatin-induced renal injury.

Abstract
BACKGROUND The multidrug resistance (MDR) of cancer cells is a major obstacle to cancer treatment. Glutathione S-transferase Pi (GSTP1-1) catalyzes the conjugation of glutathione with anticancer drugs and therefore reduces their efficacy. Phenolic compounds have the potential to inhibit GST P1-1 activity, which is a promising goal to overcome MDR and increase the efficacy of chemotherapy. RESULTS Three fractions (dichloromethane, ethyl acetate, and n-butanol) were prepared from Tamarindus indica seeds to determine their phenolic and flavonoid properties as well as their antioxidant/pro-oxidant properties. The n-butanol fraction displayed the highest levels of phenol ( 378 ± 11.7 mg gallic acid equivalent/g DW) and flavonoids (83 ± 6.0 mg rutin equivalent/g DW). Inhibiting effects on purified GSTP1-1 activity in human erythrocytes (eGST), placenta (pGST), and hGSTP1-1 have been studied. The n-butanol fraction was the most effective in inhibiting eGST, hGSTP1-1, and pGST with IC50 values of 3.0 ± 0.7, 4.85 ± 0.35, and 6.6 ± 1.2 μg/ml, respectively. Cellular toxicity was investigated for the T. indica n-butanol fraction on various human cancerous cell lines. The only ones affected were MCF-7 cell lines (72%) and HePG2 (52%) indicated cytotoxicity. The value of IC50 is 68.5 μg/ml of T. indica n-butanol fraction was observed compared to 1.7 μg/ml tamoxifen in MCF-7 cell lines. The combination of treatment of T. indica extract with the medicinally approved drug tamoxifen had unexpected effects; complete elimination of the cytotoxic inhibition effect of tamoxifen and the plant extract was observed. CONCLUSIONS However T. indica extract has a cytotoxic effect on the MCF-7 cell line; in certain situations, plant products can have an opposite effect to the intended drug, which decreases the impact of the drug.

Abstract
With the alarming rise in incidence of antibiotic-resistant bacteria and the scarcity of newly developed antibiotics, it is imperative that we design more effective formulations for already marketed antimicrobial agents. Fusidic acid (FA), one of the most widely used antibiotics in the topical treatment of several skin and eye infections, suffers from poor water-solubility, sub-optimal therapeutic efficacy, and a significant rise in FA-resistant Staphylococcus aureus (FRSA). In this work, the physico-chemical characteristics of FA were modified by nanocrystallization and lyophilization to improve its therapeutic efficacy through the dermal route. FA-nanocrystals (NC) were prepared using a modified nanoprecipitation technique and the influence of several formulation/process variables on the prepared FA-NC characteristics were optimized using full factorial statistical design. The optimized FA-NC formulation was evaluated before and after lyophilization by several in-vitro, ex-vivo, and microbiological tests. Furthermore, the lyophilized FA-NC formulation was incorporated into a cream product and its topical antibacterial efficacy was assessed in vivo using a rat excision wound infection model. Surface morphology of optimized FA-NC showed spherical particles with a mean particle size of 115 nm, span value of 1.6 and zeta potential of −11.6 mV. Differential scanning calorimetry and powder X-ray diffractometry confirmed the crystallinity of FA following nanocrystallization and lyophilization. In-vitro results showed a 10-fold increase in the saturation solubility of FA-NC while ex-vivo skin permeation studies showed a 2-fold increase in FA dermal deposition from FA-NC compared to coarse FA. Microbiological studies revealed a 4-fofd decrease in the MIC against S. aureus and S. epidermidis from FA-NC cream compared to commercial Fucidin cream. In-vivo results showed that FA-NC cream improved FA distribution and enhanced bacterial exposure in the infected wound, resulting in increased therapeutic efficacy when compared to coarse FA marketed as Fucidin cream.

Abstract
Valproic acid is a commonly used drug for many psychiatric disorders, particularly for epilepsy. However, it has been reported that its use is associated with possible side effects including hepatotoxicity. The present study investigated the hepatoprotective effect of ellagic acid against valproic acid-induced hepatotoxicity in rats. Ellagic acid (60 mg/kg/day; p.o) was treated for one week, followed by concomitant injection of valproic acid (250 mg/kg/day; i.p.) for another 14 consecutive days to induce hepatocellular damage in adult Sprague-Dawley rats. Valproic acid showed a marked increase in serum enzyme activities, AST, ALT, ALP and GGT. In addition, it significantly increased MDA and NO along with a marked decline in reduced GSH content. At the same time, valproic acid administration resulted in marked elevation in hydroxyproline, TNF-α production and NF-kB expression. These results were confirmed by histopathological examination. Treatment with ellagic acid markedly attenuated valproic acid-induced hepatic injury in rats.

Abstract
Aim Liver fibrosis represents a massive global health burden with limited therapeutic options. Thus, the need for curative options is evident. Thus, this study aimed to assess the potential antifibrotic effect of honokiol in Concanavalin A (Con A) induced immunological model of liver fibrosis as well the possible underlying molecular mechanisms. METHODS Male Sprague-Dawley rats were treated with either Con A (20 mg/kg, IV) and/or honokiol (10 mg/kg, orally) for 4 weeks. Hepatotoxicity indices were as well as histopathological evaluation was done. Hepatic fibrosis was assessed by measuring alpha smooth muscle actin (α-SMA) expression and collagen fibers deposition by Masson's trichrome stain and hydroxyproline content. To elucidate the underlying molecular mechanisms, the effect of honokiol on oxidative stress, inflammatory markers as well as transforming growth factor beta (TGF-β)/SMAD and mitogen-activated protein kinase (MAPK) pathways was assessed. KEY FINDINGS Honokiol effectively reversed the hepatotoxicity indices elevations and abnormal histopathological changes induced by Con A. Besides, honokiol attenuated Con A-induced liver fibrosis by down-regulation of hydroxyproline levels, α-SMA expression together with a marked decrease in collagen fibers deposition. Mechanistically Con A induced oxidative stress, provocation of inflammatory responses and activation of TGF-β/SMAD/MAPK pathways. Contrariwise, honokiol co-treatment significantly restored antioxidant defence mechanisms, down-regulated inflammatory cascades and inhibited TGF-β/SMAD/MAPK signaling pathways. CONCLUSION The results provide an evidence for the promising antifibrotic effect of honokiol that could be partially due to suppressing oxidative stress and inflammatory processes as well as inhibition of TGF-β/SMAD/MAPK signaling pathways.

Abstract
BACKGROUND AND PURPOSE Reduced male fertility has been regarded as a serious complication of rheumatoid arthritis. Phytochemicals have been described as protective agents against rheumatoid arthritis-linked testicular impairment. The current study aimed to investigate the potential protective effects of ellagic acid on rheumatoid arthritis-evoked testicular dysfunction vis-à-vis the reference anti-inflammatory celecoxib. EXPERIMENTAL APPROACH Ellagic acid (50 mg/kg/day) and celecoxib (5 mg/kg/day) were administered orally for 20 days in adjuvant-induced arthritic rats. KEY FINDINGS Current data revealed that ellagic acid counteracted rheumatoid arthritis-evoked testicular histopathologic changes, disrupted sperm characteristics and low gonadosomatic index with comparable efficacy to celecoxib. Ellagic acid also enhanced the testicular steroidogenesis via upregulating the gene expression of 3β-hydroxysteroid dehydrogenase, 17β-hydroxysteroid dehydrogenase and steroidogenic acute regulatory protein with consequent boosting of serum testosterone. Notably, ellagic acid attenuated the testicular inflammatory responses through suppression of myeloperoxidase, tumor necrosis factor-α and cyclo-oxygenase-2 protein expression together with enhancing the anti-inflammatory signal interleukin 10. Ellagic acid also curbed the redox alterations via lowering the production of lipid peroxides and nitric oxide and elevation of the anti-oxidant reduced glutathione. In support of cell survival, ellagic acid combated testicular apoptosis through downregulating caspase-3 protein expression. SIGNIFICANCE The present work accentuates the beneficial actions of ellagic acid in rheumatoid arthritis-incurred testicular impairment and disrupted spermatogenesis via combating the inflammatory, oxidative and apoptotic aberrations.

Abstract
Methotrexate (MTX) is commonly used to treat several types of cancer and autoimmune diseases. However, there is increasing concern over its organs toxicities particularly liver toxicity. Liraglutide, a glucagon like peptide-1 agonist, possesses antioxidant and anti-inflammatory features. This study aimed to explore the potential protective effect of liraglutide pre-treatment in ameliorating MTX-induced hepatotoxicity and to further investigate the underlying mechanisms. Rats received 1.2 mg/kg liraglutide intraperitoneal twice daily for 7 days before MTX. Results revealed that liraglutide significantly decreased activities of liver enzymes and oxidative stress in hepatocytes. Furthermore, NF-kB expression and related inflammatory markers (TNF-α, COX-2 and IL-6) were reduced in the pre-treatment group of liraglutide. These data validate the advantageous effects of liraglutide in MTX hepatotoxic animals. In addition, liraglutide increased the expression of the antioxidant transcription factor nuclear factor-erythroid 2-related factor 2 (Nrf-2), along with the transcription of downstream phosphorylated cAMP response element-binding protein (pCREB) which increases the activity of Nrf-2. Additionally, caspase-3 expression/activity and BAX/Bcl-2 ratio were decreased following liraglutide pre-treatment. In conclusion, it was confirmed that liraglutide enhanced the antioxidant activity of liver cells by activating the Nrf-2 and pCREB signaling, thereby, reducing liver cell inflammation and apoptosis induced by MTX.

Abstract
Rheumatoid arthritis (RA) is a chronic and progressive autoimmune inflammatory disease associated with irreversible joint destruction that leads to permanent motor disability and compromised quality of life. However, the main cause of RA is still unknown though stimulation of immune system and cells plays pivotal role in disease development and progression. Ramucirumab (RAM) is the monoclonal antibody against VEGF- receptor. This study aimed to investigate and evaluate the therapeutic effect of RAM with or without Methotrexate (MTX) against adjuvant-induced arthritis in rats. Complete Freund's adjuvant (CFA)-induced arthritic rats were treated for three consecutive weeks with MTX or RAM alone and MTX-RAM co-therapy. Arthritic score, gait score, ankle diameter, paw thickness, angiogenic, inflammatory cytokines, bone erosion markers, and apoptotic markers were assessed to evaluate the anti-arthritic effect. RAM monotherapy exhibited anti-inflammatory, anti-angiogenic and anti-apoptotic effects similar to MTX alone to treat RA in the current study. Furthermore, RAM alone had a protective effect on bone and cartilage health better than standard anti-rheumatic agent MTX. Interestingly, combined therapy of MTX and RAM produced significant differences in comparison with MTX or RAM monotherapy in all tested parameters. Moreover, the current study proved that MTX-RAM co-therapy has a synergistic effect.

Abstract
Nicorandil ameliorated doxorubicin-induced nephrotoxicity; this study aimed to show and explain the mechanism of this protection. A precise method was elucidated to study the effect of nicorandil on doxorubicin-induced nephrotoxicity in rats depending on the critical inflammation pathway TLR4/MAPK P38/NFκ-B. Adult male rats were subdivided into four groups. The 1st group was normal control, the 2nd group received nicorandil (3 mg/kg; p.o., for 4 weeks), the 3rd group received doxorubicin (2.6 mg/kg, i.p., twice per week for 4 weeks), and the fourth group was combination of doxorubicin and nicorandil for 4 weeks. Nephrotoxicity was assessed by biochemical tests through measuring Kidney function biomarkers such as [serum levels of urea, creatinine, albumin and total protein] besides renal kidney injury molecule-1 (KIM-1) and cystatin C], oxidative stress parameters such as [renal tissue malondialdehyde (MDA), reduced glutathione (GSH), SOD, catalase and nrf-2], mediators of inflammation such as [Toll like receptor 4 (TLR-4), Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB), p38 MAPK, Interleukin 1 beta (IL-1 β), and Tumor necrosis factor alpha (TNF-α)] and markers of apoptosis [BAX and Bcl-2 in renal tissue]. Finally, our data were supported by histopathology examination. Nicorandil pretreatment resulted in a significant decrease in nephrotoxicity biomarkers, oxidative stress markers, inflammatory mediators and prevented apoptosis through decreasing BAX and increasing Bcl-2 in renal tissues. Nicorandil prevented all the histological alterations caused by doxorubicin. Nicorandil is a promising antidote against doxorubicin-induced nephrotoxicity by neutralizing all toxicity mechanisms caused by doxorubicin through normalizing inflammatory cascade of TLR4/MAPK P38/NFκ-B.

Abstract
Cisplatin, a platinum chemotherapeutic agent, is used in a diversity of malignancies; nevertheless, the excessive nephrotoxicity following cisplatin treatment is the dose-limiting devastating reaction. This study was designed to explore the possible nephroprotective impact of wogonin, a forceful anti-oxidant, anti-inflammatory, and anti-tumor agent, in a rat model of cisplatin-induced renal injury. The potential nephroprotective mechanisms were additionally investigated. Wogonin was given at a dose of 40 mg/kg. Acute nephrotoxicity was indicated by a significant rise in BUN, and serum creatinine levels in cisplatin-injected rats. Also, cisplatin enhanced the lipid peroxidation, diminished GSH, catalase, and PPAR-γ levels. Additionally, cisplatin-injected rats showed a significant rise in tissue levels of IL-1β, TNF-α, NF-kB, and caspase-3 enzymatic activity. Notably, the pre-treatment with wogonin ameliorated the nephrotoxicity indices, oxidative stress, inflammation, and apoptosis induced by cisplatin. Also, wogonin up-regulated PPAR-γ expression. The involvement of Wnt/β-catenin pathway was debatable; however, our findings showed that it was significantly induced by cisplatin. Wogonin pre-treatment markedly attenuated Wnt/β-catenin pathway. Collectively, these findings imply that wogonin is a promising nephroprotective agent that improves the therapeutic index of cisplatin via reducing oxidative stress, inflammation as well as inducing PPAR-γ. Also, Wnt/β-catenin pathway is partially involved in the pathogenesis of cisplatin nephrotoxicity.

Abstract
BACKGROUND Exposing patients with metastatic colorectal cancer (mcrc) to all three active chemotherapeutic agents (oxaliplatin, irinotecan, fluorouracil) has improved survival. The benefit of second-line chemotherapy after a first-line triplet is not clearly defined. We evaluated the efficacy of second-line chemotherapy in patients who had received first-line triplet therapy. METHODS The medical records of patients treated on a prospective trial of first-line triplet therapy were reviewed for second-line treatment. Univariate and multivariate analyses were performed to establish factors of prognostic significance. RESULTS Of the 53 patients who received first-line triplet therapy, 28 (53%) received second-line chemotherapy [13 men; 8 with a colon primary; mutant KRAS in 10, wild-type in 15, and unknown status in 3; Eastern Cooperative Oncology Group performance status (ps) of 1 in 16 patients, ps 2 in 3, ps 3 in 2, and unknown in 7; involved organs: liver in 17 patients, lung in 16, and peritoneum in 8]. Second-line chemotherapy consisted of xelox or folfox in 13 patients, xeliri or folfiri in 12, and single-agent irinotecan in 3. Concurrent bevacizumab was given in 16 patients (57%), and cetuximab, in 2 (7%). Median survival was 28.0 months [95% confidence interval (ci): 22.8 months to 33.2 months] for patients receiving second-line therapy and 23.0 months (95% ci: 13.2 months to 32.8 months) for those not receiving it. Best response was partial in 6 patients (21%), stable disease in 11 (39%), and progressive disease in 11 (39%). Median progression-free survival was 4.8 months (95% ci: 2.4 months to 9.6 months), and overall survival was 15 months (95% ci: 9.6 months to 20.4 months). CONCLUSIONS Second-line chemotherapy after first-line triplet therapy in mcrc is feasible and suggests efficacy comparable to that reported for second-line therapy after a doublet, regardless of the agent used.

Abstract
Possible hepatoprotective effect of Curcuma longa and/or Nigella sativa against hepatotoxicity induced by coadministration of sodium valproate (SV) and paracetamol was studied. Rats were divided into 10 groups, control groups 1, 2, 3, and 4 received vehicles, C. longa (200 mg/kg, p.o.), N. sativa (250 mg/kg, p.o.), or both herbs for 21 days, respectively. Toxicity groups 5, 6, and 7 received SV (300 mg/kg, i.p.), paracetamol (1000 mg/kg, p.o.) for the last 4 days or both for 21 days, respectively. Protection groups 8, 9, and 10 received C. longa, N. sativa, or both, respectively, 1 h before the administration of both the drugs for 21 days. SV and/or paracetamol significantly increased aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total bilirubin, relative liver/body weight ratio, malondialdehyde (MDA), tumor necrosis factor alpha (TNF-α), and caspase-3 (Casp-3) while significantly decreased albumin, total protein, glutathione (GSH) reduced, GSH peroxidase, and superoxide dismutase (SOD). Preadministration of C. longa and/or N. sativa caused protective effect against the hepatotoxicity induced by both drugs.

Abstract
Mesenchymal stem cells (MSCs) are an ideal adult stem cell with capacity for self-renewal and differentiation with an extensive tissue distribution. The present study evaluates the therapeutic effects of bone marrow mesenchymal stem cells (BM-MSCs) or adipose-derived mesenchymal stem cells (AD-MSCs) against the development of methotrexate (MTX)-induced cardiac fibrosis versus dexamethasone (DEX). Rats were allocated into five groups; group 1, received normal saline orally; group 2, received MTX (14 mg/kg/week for 2 weeks); groups 3 and 4, treated once with 2 × 106 cells of MTX + BM-MSCs and MTX + AD-MSCs, respectively; and group 5, MTX + DEX (0.5 mg/kg, for 7 days, P.O.). MTX induced cardiac fibrosis as marked changes in oxidative biomarkers and elevation of triglyceride, cholesterol, aspartate aminotransferase, gamma-glutamyl transferase, creatine kinase, and caspase-3, as well as deposited collagen. These injurious effects were antagonized after treatment with MSCs. So, MSCs possessed antioxidant, antiapoptotic, as well antifibrotic effects, which will perhaps initiate them as notable prospective for the treatment of cardiac fibrosis.

Abstract
Exposure to drugs often results in toxicity in the kidney which represents the major control system maintaining homeostasis of the body and thus is especially susceptible to xenobiotics. Nephrotoxicity is a life-threatening side-effect of nonsteroidal anti-inflammatory drugs (NSAIDs). Diclofenac is one of the most frequently prescribed NSAIDs and have been reported to cause multiple organs damage. Curcumin (CUR) exhibits nephroprotective properties. Therefore, rats were divided into four groups; rats of groups 3 and 4 received diclofenac (100 mg/kg, i.m.), whereas rats of groups 2 and 4 received CUR (100 mg/kg, p.o.) for 3 days. Diclofenac revealed a significant increase in urea and creatinine levels and malondialdehyde concentration and marked reduction in catalase activity and reduced glutathione concentration. Histopathologically, diclofenac produced fatty changes and eosinophilic casts were detected in the renal tubules, those were attenuated by administration of CUR prior diclofenac.
