Photothermal effectiveness of microporous carbon nanospheres incorporated with polysulfone in direct contact membrane distillation.

Carbon nano-spheres (CNS) were synthesized a hydrothermal method using d-glucose as a precursor, followed by pyrolysis in a nitrogen atmosphere. The resulting CNS were integrated into polysulfone (PSF) membranes to enhance their photothermal properties. Characterization using various techniques revealed improved thermal properties upon CNS inclusion, with a notable increase in membrane surface temperature and enhancement of contact angle (CA) and liquid entry pressure (LEP).

Fluorescent sensor/tracker for biocompatible and real-time monitoring of ultra-trace arsenic toxicants in living cells.

Real-time monitoring and tracking of extreme toxins that penetrate into living cells by using biocompatible, low-cost visual detection via fluorescent monitors are vitally essential to reduce health hazards. Herein, we report a simple engineering design of biocompatible and fluorescent sensors/trackers for real-time monitoring and ultra-trace tracking (up to ppb) of extremely toxic substances (such as arsenic species) in living cells. The biocompatible As(V) sensor (BAS) design is fabricated via successful dressing/decoration process of 2-hydroxy 5-methyl isophthalaldehyde fluorescent receptor into hierarchical organic-inorganic carriers that have micro-hollow geodes, swirled caves and nest-shaped cages, and uniform cubic structures.

Penile reconstruction after complete bladder exstrophy repair.

Introduction: The decreased penile length in patients born with bladder exstrophy (BE) results partly from pubic symphysis diastasis and the separation of the corporal bodies. Also, intrinsic shortening of anterior corporal compartment, residual penile dorsal curvature, and postsurgical scarred skin share in creation of short penile length.

Objective: The goal of this study was to look at whether adult men who had bladder exstrophy (BE) surgery as babies needed and benefited from penile reconstruction, which included penile lengthening and repair of any redo penile pathology that was present at the same time.

The synergistic effect of ultrasound power and magnetite incorporation on the sorption/desorption behavior of Cr(VI) and As(V) oxoanions in an aqueous system.

Though abundant studies have targeted the sorption of Cr(VI) and As(V) anions by organic polymers or magnetic metal oxides, there is no research literature on the sorption characteristics of Cr(VI) and As(V) by thiourea-formaldehyde resin (TF) and its magnetic derivative (MTF). TF resin is a strong chelating agent, which has several practical applications. This paper reports on the removal of Cr(VI) and As(V) oxoanions by TF and MTF sorbents.

A Simple Immunohistochemical Panel Could Predict and Correlate to Clinicopathologic and Molecular Subgroups of Urinary Bladder Urothelial Carcinoma.

Background: Although gene expression profiling provided a comprehensive molecular characterization of different subtypes of bladder urothelial carcinoma (UC), which are distinct in their biological features and prognosis, such a system is not yet applicable for routine clinical practice. This study aimed to examine the expression of these molecular classes of UC using simple panel of immunohistochemical markers.
