New inorganic inhibitors derived from cefotaxime to enhance corrosion resistance of mild steel in 3% NaCl.

To overcome the threat of corrosion and its cost, a new Schiff base was prepared and utilized to synthesize inorganic inhibitors to enhance corrosion resistance and reduce current density. The Schiff base was obtained from the interaction of cefotaxime with acetylacetone, while H NMR and IR spectra were used to confirm the preparation. Moreover, Fe, Co, Ni and Cu metal salts were reacted with the Schiff base to give the corresponding complexes.

Effect of body mass index on prostate volume and prostate-specific antigen in men over 50: A cross-sectional study.

Objectives: To assess the relationship between body mass index (BMI) and prostatic-specific antigen (PSA) levels, and prostate volume (PV) in men over 50 years.

Methods: This cross-sectional study was conducted at the Urology Outpatient Clinic at Badr Hospital and 15th May Hospital over a period of 6 months on 300 male patients over 50 years of age. The international prostate symptom score (IPSS) was used to evaluate the severity of lower tract urinary symptoms.
