Scalp Metastasis From Renal Cell Carcinoma: A Rare Case With Rapid Progression.

Renal cell carcinoma (RCC) is a common renal malignancy that frequently metastasizes, though cutaneous metastasis, particularly to the scalp, is rare and generally indicates a poor prognosis. We report a case of scalp metastasis from RCC in a 69-year-old man who presented with unexplained weight loss and painless hematuria. Imaging revealed a 12-cm renal mass with adrenal, pulmonary, and scalp metastases.

Comparing the remineralization potential of undemineralized dentin powder versus chicken eggshell powder on artificially induced initial enamel carious lesions: an in-vitro investigation.

Background: White spot lesions are a widespread undesirable effect, especially prevalent during fixed orthodontic treatments. The study compared the in vitro enamel remineralization potential of undemineralized dentin matrix (UDD) versus chicken eggshell powder (CESP) for artificially induced enamel lesions.

Methods: 100 caries-free and sound maxillary premolars were randomly divided into four groups each contain 25 teeth: Group I (Baseline): No treatment was done to the enamel surface.

Bone lid technique versus standard technique for treatment of mandibular lesions.

Background: Jaw lesions are frequent in the oral and maxillofacial areas. Different methods for enucleating jaw lesions in the oral and maxillofacial sites have been proposed, including the bone lid technique.

Purpose: The aim of this study was to compare the clinical and radiographic results of the bone lid technique employing a piezoelectric surgery to the traditional technique in individuals with mandibular lesions.

A pedicled buccal periosteal flap for the closure of oro-antral fistula.

Background: An oroantral fistula is a communication between the maxillary antrum and oral cavity. This pathological communication is formed mainly due to dental extraction of maxillary premolars and molars. Adequate management should include closing the oroantral fistula and eliminating sinus infections to prevent recurrence and sinusitis.

Synergistic Effects of Kaolin and Silicon Nanoparticles for Ameliorating Deficit Irrigation Stress in Maize Plants by Upregulating Antioxidant Defense Systems.

Water deficit is a significant environmental stress that has a negative impact on plant growth and yield. In this research, the positive significance of kaolin and SiO nanoparticles in moderating the detrimental effects of water deficit on maize plant growth and yield is investigated. The foliar application of kaolin (3 and 6%) and SiO NPs (1.
