Fat, sugar, theobromine, and caffeine are important compounds in chocolates that influence the physico-chemical and sensory characteristics of the products. These parameters commonly are determined with conventional, time-consuming, environmentally pollutant methods. In this study, near infrared spectroscopy (NIRS) coupled with partial least square regression (PLSR) was used to predict the quantity of these compounds.

The prognostic and incremental value of left anterior descending coronary artery TDE-CFR above myocardial perfusion scintigraphy in patients with suspected myocardial ischemia has not yet been studied.
Methods And Results: Three hundred seventy-one patients (mean age, 62.
In France, domestic waste production is estimated at c 350 kg year per person and landfilling still represents a predominant way of municipal solid waste management, with 39% of waste dumped in 2007. Waste characterization campaigns were conducted at different stages of a mechanical-biological treatment process in order to evaluate its efficiency. Waste samples were sorted by size (>100 mm, <100-20 mm and <20 mm) in order to assess the opportunity for mechanical and aerobic degradation and to reduce the volume of waste landfilled.

Here we investigated the 17-year trends in incidence and prognosis of AMI-induced cardiogenic shock in Västra Götaland in western Sweden, an area with approximately 1.6 million inhabitants.

- A study was conducted on chronic total occlusions (CTO) in coronary arteries using data from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) to investigate the prevalence and patient characteristics.
- Out of over 215,000 patients, 16,818 had confirmed CTO, representing 10.9% of all angiographies; most were treated conservatively, with only 5.8% undergoing percutaneous coronary intervention (PCI).
- The findings suggest that CTO is common yet under-treated in Sweden, highlighting the need for more research on optimal treatment strategies for this high-risk patient group.
