Municipal water recycling may expose humans and the environment to trace organic contaminants. We assessed biological activated carbon (BAC) filtration for removal of organic micropollutants (MPs). Adsorption experiments were carried out in batch reactors containing secondary effluent and new granular activated carbon (GAC) and preloaded BAC media. Results show that BAC has good potential for r...

Unique sampling techniques have generated a new understanding regarding the fate of volatile organic compounds (VOCs) in phytoremediation systems. Tissue sampling and diffusion traps were used to determine how VOCs are transported in and diffuse from vegetation, particularly woody species. These techniques were then utilized to observe how plants interact with different contaminated media, show...

The removal of sulfur by deep hydrodesulfurization is expensive and environmentally unfriendly. Additionally, not separated completely from heterocyclic poly-aromatic compounds. In nature, several microorganisms (Rhodococcus erythropolis IGTS8, Gordonia sp., Bacillus Mycobacterium Paenibacillus sp. A11-2 etc.) have been reported to remove petroleum fractions. All these microbes recalcitrant org...

Dystrophic calcifications have been detected in the prostatic fossa, especially after de-obstructing procedures or radiotherapy for prostate cancer. These calcifications can be recalcitrant in patients with poor tissue healing. Hyperbaric Oxygen (HBO) therapy has multiple applications in urology but has not been reported as a treatment of recalcitrant dystrophic calcifications of the prostatic ...

Ulnar nerve neuropathy at the elbow represents the second most frequent compression neuropathy of the upper extremity. Of the five different anatomical areas responsible for ulnar nerve compression at the elbow region, the epitrochlear-olecranon channel and Osborne’s arcade are the most common. An additional cause of nerve damage is a dynamic process in which the ulnar nerve dislocates anterior...

As Trichomonas vaginalis infects the urethra, Bartholin’s and Skene’s glands, as well as the vagina systemic treatment for trichomoniasis is recommended. The only group of drugs with safe, proved, systemic eYcacy is the imidazoles and the most widely used agent is metronidazole. When antimicrobial resistance arises it is likely to be shared across the group. Metronidazole resistant strains have...

Nonsedating antihistamines are the fi rst-choice treatment for all forms of urticaria. In patients with recalcitrant urticaria who do not respond to conventional doses of antihistamines, current guidelines recommend increasing doses by up to 4 times in order to obtain better control of the disease. Although few studies have been conducted, there are convincing data from controlled trials for ce...
