The aim of this study was to investigate the effect of thermogenic supplementation on the bone tissue of rats subjected to orthodontic movement. A total of 38 male Wistar rats underwent orthodontic movement of the left permanent maxillary first molars for 21 days. The rats were assigned to three groups: Control group: water; Thermogenic 1: C4 Beta Pump thermogenic; or Thermogenic 2: PRE-HD/Pre-workout.

Bacterial resistance is a major public health challenge. In Gram-negative bacteria, the synergy between multidrug efflux pumps and outer membrane impermeability determines the intracellular concentration of antibiotics. Consequently, it also dictates antibiotic activity on their respective targets.

Resonant inelastic X-ray scattering (RIXS) is an ideal X-ray spectroscopy method to push the combination of energy and time resolutions to the Fourier transform ultimate limit, because it is unaffected by the core-hole lifetime energy broadening. Also, in pump-probe experiments the interaction time is made very short by the same core-hole lifetime. RIXS is very photon hungry so it takes great advantage from high-repetition-rate pulsed X-ray sources like the European XFEL.

Six months following modified Bentall procedure a patient presented with angina and acute ST depression. CT coronary angiogram revealed severe narrowing of the left main coronary artery. Minimal invasive off pump coronary artery bypass grafting avoided complex reoperative surgery and delivered an excellent clinical outcome.

In determining the culprit vessel responsible for inferior ST-segment elevation myocardial infarction (STEMI) as either the right coronary artery (RCA) or left circumflex (LCX), the electrocardiographic value has been validated. However, its ability to predict whether inferior STEMI is complicated by left anterior descending artery (LAD) chronic total occlusion remains uncertain. Based on the involvement of arteries other than the culprit vessels, 189 patients with inferior STEMI from our chest pain center were categorized into four groups: LAD occlusion group (n = 20), LAD stenosis > 50% group (n = 116), normal LAD group (n = 27), and other vessel stenosis > 50% group (n = 26).
