Polyindole Embedded Nickel/Zinc Oxide Nanocomposites for High-Performance Energy Storage Applications.

Conducting polymers integrated with metal oxides create opportunities for hybrid capacitive electrodes. In this work, we report a one-pot oxidative polymerization for the synthesis of integrated conductive polyindole/nickel oxide (PIn/NiO), polyindole/zinc oxide (PIn/ZnO), and polyindole/nickel oxide/zinc oxide (PNZ). The polymers were analyzed thoroughly for their composition and physical as well as chemical properties by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), ultraviolet-visible spectroscopy (UV-Vis), and thermogravimetric analysis (TGA).

A generative adversarial network for artifact removal in photoacoustic computed tomography with a linear-array transducer.

Unlabelled: With balanced spatial resolution, penetration depth, and imaging speed, photoacoustic computed tomography (PACT) is promising for clinical translation such as in breast cancer screening, functional brain imaging, and surgical guidance. Typically using a linear ultrasound (US) transducer array, PACT has great flexibility for hand-held applications. However, the linear US transducer array has a limited detection angle range and frequency bandwidth, resulting in limited-view and limited-bandwidth artifacts in the reconstructed PACT images.

Imaging the aged brain: pertinence and methods.

The global population is ageing at an accelerating speed. The ability to perform working memory tasks together with rapid processing becomes increasingly difficult with increases in age. With increasing national average life spans and a rise in the prevalence of age-related disease, it is pertinent to discuss the unique perspectives that can be gained from imaging the aged brain.

Awareness of risk factors and fallacies associated with urinary bladder cancer in our population: A prospective survey.

Objective: To determine the awareness of risk factors for bladder cancer and false beliefs associated with this disease.

Methods: This cross-sectional study was conducted at the Kidney Centre, Karachi, from January to February 2015, and comprised subjects who presented to the various in-house clinics. The subjects were interviewed using a questionnaire comprising demographic parameters, level of education and awareness of smoking hazards, knowledge and false beliefs associated with bladder cancer.

Hypogonadotropic hypogonadism: new identification of testicular blood flow and varicocele after treatment with gonadotropins.

Objective: To investigate testicular changes in patients with hypogonadotropic hypogonadism (HH) after treatment with gonadotropins.

Design: Patients with HH were investigated and followed before and after treatment.

Setting: Urology and andrology clinic of a teaching hospital.
