Purpose: Evaluate the renal blood flow by using a laser flow meter, Laserflow Vasamedics®, after the ischemia/reperfusion in two different times of the arterial renal vessel clamping.
Methods: The renal blood flow was evaluated by using a laser flow meter after two different times of ischemia/reperfusion procedure, 30 and 60 minutes. It was used 20 Wistar male rats, divided in two groups of 10 rats: Group A (30 minutes of ischemia on the left kidney, with later analysis of the blood flow in 1, 5 and 20, after the renal reperfusion start) and Group B (60 minutes of ischemia on the left kidney, with later analysis of the blood flow in 1, 5 and 20 minutes, after the renal reperfusion start).
Results: In the first minute, there were not significant differences between the two groups (p=0.789). In the 5th minute there were not significant differences also, but there was a tendency (p=0.068). In the 20th minute, there was a significant difference between the 2 groups (p=0.022). When the means are observed, it is possible to notice that Group A has a larger flux than Group B.
Conclusion: The kidneys submitted to 30' of ischemia/reperfusion are subject to a larger restitution of the blood flow in comparison to the Group which had a longer time.

Blood flow restriction exercise (BFRE) is a therapeutic approach traditionally used to facilitate muscular strength and hypertrophy. Emerging evidence has identified its benefits on other systems and metabolic processes. The emphasis of this study was to examine potential impact of BFRE on serum levels of tissue plasminogen activator (tPA).

Purpose: The purpose of this study is to evaluate the influence of photobiomodulation therapy on the regenerative potential of non-vital mature permanent teeth of healthy Canine dogs.
Methods: 54 mature roots, obtained from 27 premolars, in dogs, were selected and divided into three equal groups where Group I received regenerative endodontic procedures (REPs) using blood clot as a scaffold (positive control), Group II received similar treatment as Group I, followed by photobiomodulation therapy (study group) and Group III did not receive any intervention (negative control). Each group was further divided into three equal subgroups for the evaluation of the vascular area percentage and fibroblast count at 3 different intervals; 3, 10, and 15 weeks.

Blast quantification in the bone marrow (BM) is crucial for evaluating myeloid neoplasms, with cytomorphology being the only recognized analysis. The CD34 myeloid cell (CD34M) count by flow cytometry is promising but impaired by BM hemodilution. A modified version of the Holdrinet index (mHI) is routinely used to assess it, though not yet validated.

Acute ischemic stroke (AIS) is a significant brain disease with a high mortality and disability rate. Additional therapies for AIS are urgently needed, and neuroplasticity mechanisms by agents are expected to be neuroprotective for AIS. As a major active component of Salvia miltiorrhiza, salvianolic acid A (SAA) has shown potential for preventing cardiovascular diseases.
