Anderson and Dyck claim that the current trend of almost exclusively using citation-based evaluative metrics to assess the research output of scholars is unsound. I agree with them in this, but I feel that, for practical reasons, this system will not disappear in the near future, so we must concentrate ...

Abstract Objective. Leiomyomata are benign neoplasms that are rarely encountered in the genitourinary tract outside the uterus. Pathological confirmation is always needed for definitive diagnosis, in order to rule out malignancies such as leiomyosarcoma. In cases of small leiomyomata, a surveillance strategy can be suggested, although the preferred approach is ...

The regioselective synthesis of pyrazole triflones has been achieved by 1,3-dipolar cycloaddition of triflyl alkynes and hydrazonoyl chloride in the presence of Hünig's base. Pyrazolo[5,1-a]isoquinoline triflones were also regioselectively synthesized for the first time via tandem 1,3-dipolar cycloaddition/oxidative aromatization between triflyl alkynes and C,N-cyclic azomethine imines.

The biosynthesis of glycogen or starch is a main strategy developed by living organisms for the intracellular storage of carbon and energy. In phototrophic organisms, such polyglucans accumulate due to carbon fixation during photosynthesis and are used to provide maintenance energy for cell integrity, function and viability in dark periods. ...

It was hypothesized that chronic hypoxia acclimation (preconditioning) would alter the behavioural low O(2) avoidance strategy of fish as a result of both aerobic and anaerobic physiological adaptations. Avoidance and physiological responses of juvenile snapper (Pagrus auratus) were therefore investigated following a 6 week period of moderate hypoxia exposure (10.2-12.1 ...

Abstract Radical prostatectomy remains the gold-standard surgical treatment for clinically localized prostate cancer. Contrast imaging of the upper urinary tract is not part of the routine work-up of the patient before radical prostatectomy. This may lead to rare, albeit serious complications when anatomical anomalies are present. This article reports a ...

To mitigate the diesel particle pollution problem, diesel vehicles are fitted with modern exhaust after-treatment systems (ATS), which efficiently remove engine-generated primary particles (soot and ash) and gaseous hydrocarbons. Unfortunately, ATS can promote formation of low-vapor-pressure gases, which may undergo nucleation and condensation leading to formation of nucleation particles (NUP). ...

Receptors that exhibit high selectivity are essential for potentiometric cyanide sensors. Therefore, CN- binding to metallotetraphenylporphyrins with different metal centers (i.e, Co(II), Co(III) Zn(II), Ni(II), Cu(II) and Fe(III)) was investigated. All these metalloporphyrins were found to function as neutral ionophores. Co(III) and Fe(III) tetraphenylporphyrins with their positive charges seemed likely ...

Plumes of contaminated groundwater often pass through an oxic/anoxic interface when they discharge into surface water bodies. We tested the hypothesis that contaminants recalcitrant under anaerobic conditions but degradable under aerobic conditions can be biodegraded at the interface resulting in the protection of the overlying water. Flow through columns containing ...
