RESUMO

Human cadaveric donors are essential for research in the anatomical sciences. However, many research papers in the anatomical sciences often omit a statement regarding the ethical use of the donor cadavers or, as no current standardized versions exist, use language that is extremely varied. To rectify this issue, 22 editors-in-chief of anatomical journals, representing 17 different countries, developed standardized and simplified language that can be used by authors of studies that use human cadaveric tissues. The goal of these editor recommendations is to standardize the writing approach by which the ethical use of cadaveric donors is acknowledged in anatomical studies that use donor human cadavers. Such sections in anatomical papers will help elevate our discipline and promote standardized language use in others non anatomy journals and also other media outlets that use cadaveric tissues.

RESUMO

INTRODUCTION: Psoriasis is a chronic multifactorial inflammatory disease that affects 3% of people worldwide. Ustekinumab is a selective anti-IL-12/23 biologic that alleviates psoriasis, and curcumin is a natural, effective dietary turmeric extract applied to treat numerous diseases through its antioxidant and anti-inflammatory effects. OBJECTIVE: The current study evaluated the therapeutic effects of curcumin and ustekinumab cotherapy (CUC) on imiquimod (IQ)-induced psoriasis in a rat model. MATERIALS AND METHODS: Twenty rats were divided into four groups, G1 (control group), G2 (IQ-treated group), G3 (IQ + ustekinumab), and G4 (IQ + CUC). Clinical, histopathological (HP), immunohistochemical (IHC), antioxidant, and biochemical investigations evaluated the efficacy of these drugs for treating IQ induced-psoriasis. RESULTS: Rats of G2 exhibited clinical signs of psoriatic skin lesions (erythema, scaling, and skin thickening) with epidermal changes (acanthosis and parakeratosis). Additionally, the biochemical analysis revealed significant (p < 0.05) reductions in the levels of antioxidant biomarkers (SOD, GPx, and CAT) with significant (p < 0.05) elevations in psoriasis-related cytokines (TNF-α, IL-17A, IL-12P40, and IL-23). In contrast, CUC alleviated the psoriatic changes in G4 better than ustekinumab monotherapy in G3. CONCLUSIONS: Ustekinumab inhibits the inflammatory cytokines IL-12P40 and IL-23, while curcumin has antioxidant effects (increasing SOD, GPx, and CAT levels) with anti-inflammatory effects (decreasing the proinflammatory cytokine TNF-α and IL-17). Therefore, CUC could be an excellent cost-effective regimen that can improve the treatment of psoriasis by the synergistic effects of CUC.HighlightsIQ-induces psoriasis by elevating TNF-α, IL-17A, IL-12, and IL-23 and decreasing GPx, SOD, and CATUstekinumab exhibits anti-inflammatory effects by inhibiting IL-12 and IL-23Curcumin inhibits TNF-α and IL-17A, and increases GPx, SOD, and CAT levelsCUC mitigates psoriasis by synergistic antioxidant and anti-inflammatory effectsCUC inhibits TNF-α, IL-17A, IL-12, and IL-23 and increases GPx, SOD, and CAT levels.

RESUMO

BACKGROUND: Ifosfamide (IFS) has potential complications such as nephropathy and hemorrhagic cystitis (HC). Although mesna can prevent IFS-induced cystitis by direct binding and neutralization of acrolein, HC symptoms have still been observed clinically in most of these cases. Celery is a powerful healing vegetable that has antioxidant, anti-inflammatory, and anticancer effects. The current study evaluated the synergistic effects of mesna and celery seed on IFS-induced HC in rabbits. METHODS: Twenty male rabbits (four groups) were administered distilled water, IFS, mesna, and mesna+celery seed cotherapy (MCC) for three weeks. The serum and urinary bladder of experimental rabbits underwent biochemical (TNF-α, MDA, iNOS, SOD, GPx, and CAT), histopathological and ultrastructural investigations to evaluate the structural changes of the urinary bladder (UB). RESULTS: IFS injection resulted in severe cystitis with a remarkable increase in the scale of hematuria, elevations of TNF-α, MDA, and iNOS activity, and reduced activity of SOD, GPx, and CAT antioxidants. Additionally, the structure of UB exhibited evident mucosal edema and ulceration. In contrast, the MCC regimen group revealed partial synergistic improvement of all mentioned parameters. CONCLUSION: IFS induced cystitis by releasing acrolein, which exerted a significant role in the pathogenesis of HC. In contrast, the MCC intake partially ameliorated the UB damage through its antioxidant and anti-inflammatory effects.

RESUMO

Ginger or Zingiber officinale which is used in traditional medicine has been found to possess antioxidant effect that can control the generation of free radicals. Free radicals are the causes of renal cell degeneration that leads to renal failure in case of gentamicin induced toxicity. This study was done to evaluate the possible protective effects of 6-gingerol as natural antioxidant on gentamicin-induced renal cortical oxidative stress and apoptosis in adult male albino rats. Forty adult male albino rats were used in this study and were randomly divided into four groups, control group; 6-gingerol treated group; gentamicin treated group and protected group (given simultaneous 6-gingerol and gentamicin). At the end of the study, blood samples were drawn for biochemical study. Kidney sections were processed for histological, and immunohistochemical examination for caspase-3 to detect apoptosis and anti heat shock protein 47 (HSP47) to detect oxidative damage. Gentamicin treated rats revealed a highly significant increase in renal function tests, tubular dilatation with marked vacuolar degeneration and desquamation of cells, interstitial hemorrhage and cellular infiltration. Immunohistochemically, gentamicin treated rats showed a strong positive immunoreaction for caspase-3 and anti heat shock protein 47 (HSP47). Protected rats showed more or less normal biochemical, histological, and immunohistochemical pictures. In conclusion, co-administration of 6-gingerol during gentamicin 'therapy' has a significant reno-protective effect in a rat model of gentamicin-induced renal damage. It is recommended that administration of ginger with gentamicin might be beneficial in men who receive gentamicin to treat infections.

RESUMO

The sural nerve is the most commonly nerve used in nerve transplantation, and so the aim of this study was to determine the variations of the sural nerve in the back of the leg, its relations to the calcaneal tendon and lateral malleolus, and determine the patterns of its distribution on the dorsum of the foot. Twenty-four Egyptian legs and feet were dissected. The results showed that the sural communicating nerve connected with the sural nerve in 87.5%. The predominant site of union between these two nerves was in the lower one-third of the leg and ankle region (62%). There was only one right leg that the sural nerve passed through the gastrocnemius. The small saphenous vein passed along the medial side of the sural nerve in 100%. The sural nerve crossed the lateral border of the calcaneal tendon in 50%. The distance between the sural nerve and insertion of calcaneal tendon was 16 + 7 mm in 91.7%. There were four types of pattern of innervation of the toes by the sural nerve. The predominant pattern was type I (45.8%), where the lateral side of the little toe was supplied by the sural nerve alone. The second pattern was type IV (29.2%), where the lateral 2 ½ toes were supplied by the sural nerve alone. These findings are important for sural nerve biopsy and grafts, surgical repair of the calcaneal tendon, and regional anesthesia of the foot.
