Microcirculatory changes were monitored in 20 deep inferior epigastric artery perforator (DIEAP) flaps during unilateral breast reconstruction until the seventh postoperative day using laser Doppler perfusion imaging. Measurements were recorded according to the zonal classification by Scheflan and Dinner. The cutaneous territory zone IV was discarded during insetting due to marginal circulation. The highest perfusion levels were found the first postoperative day for both zones I and III. Postoperative perfusion values were significantly higher for these zones compared with zone II. Immediately after revascularization, zone I was significantly better perfused than both II and III. However, the perfusion in zone III stabilized at the level of zone I in the postoperative phase. Evaluating microcirculatory changes in the DIEAP flap with laser Doppler perfusion imaging showed that zones I and III have higher perfusion levels than zone II in the postoperative phase.

Background: There is a gap in understanding the effects of different acupoints and treatment methods (acupuncture and moxibustion) on microcirculatory changes in the lumbar region.
Objective: This study aimed to assess the thermal effects of acupuncture at Weizhong (BL40), with acupuncture at Chize (LU5) and moxibustion at both acupoints as control interventions.
Design, Setting, Participants And Interventions: In this randomized controlled trial, 140 healthy participants were equally divided into four groups: acupuncture at BL40 (Acu-BL40), acupuncture at LU5 (Acu-LU5), moxibustion at BL40 (Mox-BL40) and moxibustion at LU5 (Mox-LU5).

The SARS-CoV-2 infection manifests with diverse clinical manifestations, with severity potentially influenced by the viral variant. COVID-19 has also been shown to impact ocular microcirculation in some patients, but whether this effect varies by viral lineage remains unclear. This prospective study compared clinical features and ocular parameters assessed via optical coherence tomography angiography (OCTA) in patients recovering from SARS-CoV-2 infections during the dominance of two distinctive viral lineages, Alpha (B.

The autologous reconstruction of the female breast using a microsurgical DIEP flap is a reliable and safe method. To detect impairments early and preserve the microvascular flap through timely revision, a better understanding of physiologic perfusion dynamics is necessary. This exploratory study examines changes in microcirculation in free DIEP flaps within the first 72 h after vascular anastomosis using laser Doppler flowmetry and white-light spectrophotometry.

The aim of this study was to conduct experiments using laser speckle contrast imaging (LSCI) technology to investigate the effects of high salt diet on renal vascular reactivity in mice. LSCI is a technology for monitoring blood flow based on the laser speckle principle. It has been widely used to detect microcirculatory functions in tissues such as the skin and brain.

Human populations are experiencing unprecedented growth and longevity with lingering knowledge gaps of the characteristics, mechanisms, and pathologies of senescence. Invasive measurements and long-term control conditions for longitudinal studies are infeasible, necessitating the need for surrogate animal models. Rats have short lifespans (2-3 years) with translatable cardiovascular systems, and Sprague Dawley microcirculatory preparations are key to studying the oxygen transport mechanisms critical to the loss of skeletal muscle function in aging.
