A Design for the Dual Skin Paddle Circumflex Scapular Artery Perforator Flap for the Reconstruction of Complex Soft-Tissue Defects in Children: Anatomical Study and Clinical Applications

Conclusions The CSA system is an appropriate source for harvesting dual skin paddle CASP flap. Use of this flap for the reconstruction of complex soft-tissue defects in the extremities in children is an alternative approach that reduces morbidity and improves the cosmetic outcome at the donor site.

We report an unprecedented case of squamous cell carcinoma (SCC) in the floor of mouth of a 23-year-old woman with XP. The patient was referred to the oncologist and, two months after surgical resection, underwent a single chemotherapy and radiotherapy session. However, she died 73 hours after undergoing her first chemotherapy session. Considering the unexpected outcome of this case, we also investigated possible exacerbated adverse effects of antineoplastic treatments (especially cisplatin-based chemotherapy) in XP patients, and discussed the main characteristics of the disease, especially cases with oral manifestations d...

ConclusionSignificant metabolites could be considered as early repair markers for chronic periodontitis disease as they are being restored to achieve symbiosis. The study, therefore, concluded the early recovery process of the diseased subjects with the restoration of possible metabolomic profile similar to the healthy controls.Graphic abstract

The purpose of this study was to design and prepare the biomimetic hydrogel scaffolds mimicking cartilage extracellular matrix (ECM) with excellent performance. Hydrogels were fabricated by varying the composition and ratio of type I collagen (Col I) and modified hyaluronic acid (HA-CHO)/chondroitin sulfate (CS-ADH). The gelation of hydro...

Publication date: Available online 12 October 2019Source: Neuroscience LettersAuthor(s): Niamh B. McNamara, Veronique E. MironAbstractPerinatal brain injury (PBI) to the developing white matter results in hypomyelination of axons and can cause long-term motor and cognitive deficits e.g. cerebral palsy. There are currently no approved therapies aimed at repairing the white matter following insult, underscoring the need to investigate the mechanisms underlying the pathogenesis of PBI. Microglia have been strongly implicated, but their function and heterogeneity in this context remain poorly understood, posing a barrier to th...

In conclusion, a polypharmacology approach of combining established, prolongevity drug inhibitors of specific nodes may be the most effective way to target the nutrient-sensing network to improve late-life health. Deletion of p38α in Neurons Slows Neural Stem Cell Decline and Loss of Cognitive Function in Mice https://www.fightaging.org/archives/2019/10/deletion-of-p38%ce%b1-in-neurons-slows-neural-stem-cell-decline-and-loss-of-cognitive-function-in-mice/ Researchers here provide evidence for p38α to be involved in the regulation of diminished neural stem cell activity with age. It is thought...

This study was carried out to elucidate the antineoplastic effect of quercetin through regulating both Notch and Hh pathways, apoptosis, cell proliferation and CK2α activity.Main methodsHepatocellular carcinoma was induced in male Sprague Dawley rats by thioacetamide. Quercetin was administered in both protective and curative doses. Parameters of liver function and oxidative stress were assessed. CK2α, Notch and Hh pathways were evaluated using RT-PCR and ELISA. Apoptosis was investigated by detecting caspase-3, caspase-8 and p53. Proliferative and cell cycle markers as cyclin D1 and Ki-67 were detected immunoh...

BlindAbstract:The higher-order inositol phosphate second messengers inositol tetrakisphosphate (IP4), inositol pentakisphosphate (IP5) and inositol hexakisphosphate (IP6) are important signaling molecules that regulate DNA-damage repair, cohesin dynamics, RNA-editing, retroviral assembly, nuclear transport, phosphorylation, acetylation, crotonylation, and ubiquitination. This functional diversity has made understanding how inositol polyphosphates regulate cellular processes challenging to dissect. However, some ...

Compared with single-incision (SI) distal biceps repair, double-incision (DI) repair has been described as permitting a more anatomic repair. We hypothesized that DI repair would result in greater terminal supination torque compared with SI repair for acute distal biceps ruptures.

We sought to determine whether flow velocities measured using Doppler ultrasonography after endovascular aortic aneurysm repair (EVAR) can predict for resolution of type II endoleaks without intervention. We also assessed the relationship of the flow velocities to sac growth and the need for intervention. We hypothesized that hemodynamic properties suggesting low flow velocity would predict for resolution of type II endoleaks.
