New treatment modalities for vitiligo acting by changing certain cytokines and metalloproteinases are newly emerging. The aim of this work is to To assess the efficacy trichloroacetic acid (TCA) chemical peel, dermapen, fractional CO2 laser in stable non-segmental detect their effects on IL-17 MMP-9 levels. Thirty patients with were recruited a randomized controlled study. They randomly categorized into three equal groups. Group 1: TCA 2: dermapen machine, 3: Fractional laser. Skin biopsies...

Abstract Background Vitiligo is a pigmentary disorder associated with considerable psychological imbalance. Partial response to therapy and long duration for repigmentation are common. Meanwhile, camouflage may help through concealing vitiligo lesions improving patient confidence self‐esteem. Aim To assess the Dermatology Life Quality Index (DLQI) in patients, determine patients’ acceptance willingness utilize regularly impact of using as an adjuvant modality. Patients/Methods The study was...

Owing to the spread of resistance between pathogenic bacteria, searching for novel compounds with antibacterial activity is essential. Here, we investigated potential Greek clover or Trigonella foenum-graecum herb extract on Salmonella typhimurium clinical isolates. The chemical profile was initially determined using LC-ESI-MS/MS, which explored 36 different compounds. Interestingly, fenugreek possessed action in vitro minimum inhibitory concentrations 64 512 µg/mL. mechanism studied by...

Jasmonic acid (JA) and its derivative, methyl JA (MeJA) are hormonal cues released by plants that signal defense response to curb damages from biotic abiotic stresses. To study such response, a tropical herbal plant, Persicaria minor, which possesses pungent smell various bioactivities including antimicrobial anticancer, was treated with MeJA. Such elicitation has been performed in hairy root cultures as Arabidopsis rice, yet how MeJA influenced the proteome of an species like P. minor is...

Abstract Background Sugars and triglycerides are common carbon sources for microorganisms. Nonetheless, a systematic comparative interpretation of metabolic changes upon vegetable oil or glucose as sole source is still lacking. Selected fungi that can grow in acidic mineral salt media (MSM) with had been identified recently. Hence, this study aimed to investigate the overall metabolite an omnipotent fungus reveal at central metabolism corresponding both sources. Results Targeted non-targeted...

Abstract Background Among alopecia areata (AA) treatments, contact irritants (anthralin) and topical immunotherapies (diphenylcyclopropenone) have been successfully used. Chemoexfoliation can potentially be utilized, acting as consecutively immunomodulators. Peels via therapeutic wounding provoke growth factors cytokines that may induce hair regrowth. Aim To evaluate compare trichloroacetic acid (TCA) 35% phenol 88% peels effectiveness tolerability in patchy AA. Patients/Methods This...

The inflammatory reaction is induced by several factors like stimulation of different enzymes, oxidative stress, and production various proinflammatory mediators. Here, we elucidated the phytochemical profile Euphorbia milii ethanol extract (EMEE) then, studied its anti-inflammatory potential using a carrageenan-induced paw edema model in rats. It was found that average edoema weight substantially declined (p < 0.05) treatment with EMEE (100 mg/kg 200 mg/kg). Also, it noticed immunostaining...

In spite of multiple therapeutic regimens for vitiligo, disease relapse remains a challenge. Most guidelines consider systemic treatments only in rapidly progressive with wider surface areas. This delay halting the immune attack, may give chance further progression as well establishment resident memory T-cell population predisposing to future relapses. To assess ability early therapy localized (<2% BSA), recent onset (<6 months) vitiligo control activity and minimize possibility recurrence....
