A new perspective on quantitative assessment of photodynamic therapy mediated hydrogel nanocomposite in wound healing using objective biospeckle and morphological local-gradient.

Skin wounding is a serious public health issue, especially when considering factors that accelerate tissue recovery. Consequently, the use of photodynamic therapy (PDT) as an effective wound-healing treatment has attracted more scientific attention. Although assessing the wound healing rate is crucial for appropriate monitoring of the probability of wound healing and evaluating the treatment efficiency, the currently used techniques lack the ability to provide such information.

Comparative study on the effect of low intensity laser and growth factors on stem cells used in experimentally-induced liver fibrosis in mice.

Background And Study Aims: The therapeutic effects of human umbilical cord-derived mesenchymal stem cells (UC-MSCs) exposed to diode laser and/or hepatocyte growth factor (HGF) were compared in mice with experimental liver fibrosis induced by carbon tetra chloride (CCl).

Material And Methods: Animal model of liver cirrhosis was induced by intraperitoneal injection of CCl in a dose of 0.4ml/kg, twice a week for 6weeks.

Impact of nutritional status of Egyptian patients with end-stage liver disease on their outcomes after living donor liver transplantation.

Objective: Malnutrition is prevalent among patients with end-stage liver disease (ESLD) awaiting liver transplantation. Our aim was to examine prospectively the impact of patients' nutritional status on their outcomes after living donor liver transplantation (LDLT).

Methods: In all, 30 patients scheduled for LDLT were subjected to a preoperative nutritional status assessment through subjective global assessment (SGA), nutritional risk screening (NRS 2002) and anthropometric measurements.

Mitogenic potential inducible by He:Ne laser in human lymphocytes in vitro.

The objective of the study was to investigate the mitogenic and genotoxic effects of He:Ne laser irradiation (632.8 nm) on human peripheral lymphocytes in vitro. We used the cytokinesis-block micronucleus assay, which incorporates cytochalasin B to inhibit cytokinesis while karyokinesis proceeds normally leading to the appearance of proliferating lymphocytes as binucleated cells.
