Cholinium α-amino carboxylates, which debuted in the ionic liquid arena over a decade ago, exhibit superior stability and suitable physical properties relative to other RTILs. Although synthetic pursuits in such media, leveraging their dual role as solvents and catalysts, have been scarce so far, we herein illustrate their catalytic advantage in aza-Michael reactions in terms of low loading, acceleration and improved yields with respect to conventional conditions and other imidazolium-based ILs. These highly structured salts most likely act through multiple and cooperative non-covalent interactions.

In this study, the effect on the flowability, compressive strength, absorption, sorptivity, and carbonation resistance of concrete with different copper slag (CS) replacement ratios was investigated. For this research, four concrete mixes with different percentages of CS were made (0%, 10%, 20%, and 30% of CS as replacement of cement by volume). In addition, the microstructure was analyzed by X-ray diffraction (XRD), scanning electron microscope (SEM), and thermogravimetric analysis (TG-DTG).

Article Synopsis
  • - Urogenital schistosomiasis is a common and significant parasitic disease in sub-Saharan Africa, influenced by socio-economic factors and community behaviors.
  • - A study conducted in Cubal, Angola, with 250 participants, found that while 93.6% had some knowledge of schistosomiasis, many still held gaps in understanding symptoms and transmission, particularly among caregivers.
  • - The research identified low awareness of symptoms and risky behaviors, like washing clothes in rivers, as key factors contributing to higher infection rates in pre-school children, highlighting the need for education and prevention strategies.

Background: The ageing of the population is leading to an increase in the number of elderly patients with acute myocardial infarction. These patients are at higher risk for complications and poor medication adherence, which in turn are associated with higher healthcare resource expenditures. Nursing programmes might help to improve adherence in these complex patients.

Background: The prevalence of frailty, cognitive impairment and disability and its prognostic impact in patients with myocardial infarction undergoing primary percutaneous coronary intervention is unknown.

Aims: The aim of this study was to assess the prevalence of frailty and other ageing-related variables and their association with inhospital mortality in consecutive elderly ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention in a tertiary care hospital.

Methods: We prospectively included patients aged 75 years or older with STEMI undergoing primary percutaneous coronary intervention.

Aplasia/agenesis of lacrimal and salivary glands is a rare congenital defect that has been associated with disturbances in fibroblast growth factor 10 (FGF10). It can present with symptoms of congenital lacrimal obstruction, dry eye, and dry mouth. We report the ophthalmological and genetic study of a 19-year-old woman and her relatives suffering from this syndrome.

Fragile X-associated tremor/ataxia syndrome (FXTAS) is a late-onset neurodegenerative disorder that occurs in FMR1 premutation carriers. The prevalence of FMR1 premutation carriers in the general population is relatively high, and although rare, a premutation in both X chromosomes may occur in females inheriting a premutation allele from each of both parent carriers. Here, we report the first female with an autozygous (homozygous by descendent) FMR1 premutation allele, who fulfills neurological and radiological FXTAS findings/criteria.
