A MgAl-layered double hydroxide(MgAl-LDH)protective film was developed on AA6082 substrates via the in situ hydrothermal growth method to obtain a distinct cauliflower-like LDH structure,and coated substrates were further heat-treated in air at temperatures from 100 to 250℃ to further improve the corrosion resistance of MgAl-LDH by taking advantage of the LDH memory effect;also,the effect of calcination on MgAl-LDH structural stability and the corresponding corrosion resistance properties were *** structural characterization of uncalcined and calcined LDH films were examined using scanning electron microscopy,energy-dispersive spectroscopy,X-ray diffraction,thermogravimetric analysis,differential scanning calorimetry,and Fourier transform infrared *** corresponding corrosion protection efficiency of the developed coating was studied through potentiodynamic polarization experiments and by electrochemical impedance *** with uncalcined MgAl-LDH,the calcined film showed a relatively lower corrosion current density and a higher impedance value,especially after heat treatment at 250℃.The findings demonstrate that calcination strongly affects the oriented growth of the LDH and causes an increase in the surface area and contraction of the basal spacing,which in turn caused a compact structure that substantially influenced the LDH corrosion resistance properties.

Locally Advance Breast Cancer refers to a heterogeneous group of breast cancer with locally extensive disease, which may or may not involve the nodes, without any distant metastases. The study was conducted at Faisalabad Medical University (FMU), Oncology, Allied Hospital Faisalabad (Pakistan). Data of 100 patients with LABC was collected. Demographics were recorded in the form of age, socio-economic status. In clinical data, time of presentation, family history of breast cancer, the presenting symptom in the form of lump, ulceration and other skin changes were noted. Histo-pathological variables including tumor size, histopathology, Bloom & Richardson grading, estrogen receptor (ER), progesterone receptor status (PR) and HER2 status. Results showed that after following a standard trimodality treatment approach in LABC patients, 30 percent died within two years. Disease free survival for more than two years was observed in only 25% of patients. Whereas, 70% patients had eventful (Recurrence/metastases) survival. This poor outcome was observed due to lack of health care facilities, awareness and poor socioeconomic status.
