Update in minimally invasive periorbital rejuvenation with a focus on platelet-rich plasma: A narrative review.

2020

Background The periorbital region is among the first areas to be affected by the process of aging, which is influenced by genetic and constitutional factors. As the region plays an important role in overall facial appearance, rejuvenation of the area has immense cosmetic benefit and various treatment modalities have been used to achieve the same. Aims This article reviews commonly used non-surgical and minimally invasive modalities for periorbital rejuvenation. Methods The literature research considered published journal articles (clinical trials or scientific reviews). Studies were identified by searching electronic databases (MEDLINE and PubMed) and reference lists of respective articles.…

Evaluation of the methodological quality of articles on autologous breast reconstruction

2018

Abstract Background Breast cancer remains the most common cancer among women worldwide. Autologous breast reconstruction may contribute toward restoring body image and improving quality of life after mastectomy. This systematic literature review describes differences in the quality and type of studies investigating autologous breast reconstruction techniques over time. Methods MEDLINE was searched for articles related to the surgical techniques, namely, TRAM, LADO, DIEP, and SGAP/IGAP, for the periods 1970 to 2007 and 2008 to 2010. The quality and type of studies were compared across the two time periods. Full-texts were evaluated according to prespecified quality criteria. Results The MEDL…

Assessment of Mobilization Cost for Multiple Myeloma Using 2 Different Mobilization Strategies: High-Dose Cyclophosphamide Versus Plerixafor. on Beha…

2016

Abstract Background. Peripheral blood stem cell (PBSC) collection prior to high dose chemotherapy for autologous transplantation (ASCT) is a standard of care, and an attractive alternative to the use of bone marrow cells, for transplantation in Multiple Myeloma (MM). The optimal methodology for mobilizing PBSC has yet to be defined, both G-CSF and GM-CSF can be used; although, the stimulatory effect may be more pronounced when given after high dose cyclophosphamide (usually administered at a dose of 1.5 to 6g/m2 IV for one to two days) and use of Plerixafor, a CXCR4 antagonist (Mozobil®). The latter 2 options are preferred, overall, in France. Indeed, it was shown that the most recent combi…

Engraftment kinetics of human CD34+ cells from cord blood and mobilized peripheral blood co-transplanted into NOD/SCID mice

2004

We have reported short periods of post transplant neutropenia in human patients co-transplanted with cord blood (CB) and low numbers of haploidentical mobilized peripheral blood (MPB) CD34+ cells. To investigate the effect that the proportion of MPB to CB cells may have on engraftment kinetics, we have co-transplanted fixed numbers of human CB CD34+ cells mixed with different numbers of MPB CD34+ cells into NOD/SCID mice. We periodically quantified the proportion of human cells and the relative contribution of MPB and CB cells to the human engraftment on marrow aspirates. At the lowest MPB/CB ratios (5 : 1, 10 : 1), the contribution of CB cells predominated at all time points analyzed, and …

Atherosclerosis, inflammation and Chlamydia pneumoniae

2009

Coronary heart disease is the single most common cause of illness and death in the developed world. Coronary atherosclerosis is by far the most frequent cause of ischemic heart disease, and plaque disruption with superimposed thrombosis is the main cause of the acute coronary syndromes of unstable angina, myocardial infarction, and sudden death. Atherosclerosis is the result of a complex interaction between blood elements, disturbed flow, and vessel wall abnormality, involving several pathological processes: inflammation, with increased endothelial permeability, endothelial activation, and monocyte recruitment; growth, with smooth muscle cell proliferation, migration, and matrix synthesis; …

Quantitative study of muscle fibre atrophy and restitution after nerve grafts.

1976

Our comparative experimental studies on rabbits using clinical, electromyographical, and quantitative histological examinations of long autologous and homologous nerve grafts in 35 rabbits, paying special attention to quantitative histological changes in the gastrocnemius muscles, allow the statement that, compared to the short homografts, the long homografts showed worse results. Moreover, it became obvious that the regeneration rate of autografts was not influenced by increasing the lengths of the grafts. The answer to the question of how far even longer grafts may influence the quality of regeneration will need further investigations.

Regulation of the human bradykinin B2 receptor expressed in sf21 insect cells: A possible role for tyrosine kinases

2000

The functional regulation of the human bradykinin B2 receptor expressed in sf21 cells was studied. Human bradykinin B2 receptors were immunodetected as a band of 75–80 kDa in membranes from recombinant baculovirus-infected cells and visualized at the plasma membrane, by confocal microscopy, using an antibody against an epitope from its second extracellular loop. B2 receptors, detected in membranes by [3H-bradykinin] binding, showed a Kd of 0.66 nmol/L and an expression level of 2.57 pmol/mg of protein at 54 h postinfection. In these cells, bradykinin induced a transient increase of intracellular calcium ([Ca2+]i) in fura 2-AM loaded sf21 cells, and promoted [35S]-GTPγS binding to membranes.…

Histamine up-regulates phosphodiesterase 4 activity and reduces prostaglandin E2-inhibitory effects in human neutrophils.

2000

Objective: To investigate whether histamine produces up-regulation of phosphodiesterase (PDE) activity with functional consequences in human peripheral blood neutrophils.¶Methods: PDE activity was studied by a radioisotopic method following anion-exchange chromatography. Reverse transcriptase-polymerase chain reaction (RT-PCR) was used for detection of mRNA transcripts of PDE4 subtypes. Cyclic AMP (cAMP) levels were measured by enzyme-immunoassay, and superoxide generation by cytochrome c reduction.¶Treatment: Neutrophils were incubated for 4 h with histamine (1 μM).¶Results: PDE4 was the only isoenzyme activity increased in treated neutrophils. Kinetic analysis showed a ∼1.5-fold increase …

Prospective evaluation of parathyroid graft function after total parathyroidectomy and heterotopic autotransplantation in renal hyperparathyroidism b…

1998

The value of gradients for intact parathyroid hormone (PTH) in the assessment of graft function after total parathyroidectomy/autotransplantation for renal hyperparathyroidism was evaluated in a prospective follow-up study. Altogether 99 patients who underwent operation from August 1, 1987 to December 31, 1996 were prospectively investigated and reexamined postoperatively, including analyses of serum calcium, alkaline phosphatase, and intact PTH in the antecubital venous blood of both arms. The postoperative course is known for all patients. Of the 99 patients included in the study, 95 underwent one to nine reexaminations (median three) over follow-up periods of 1 month to 5 years (median 2…
