Innate lymphoid cells (ILC) are a recently discovered group of innate lymphocytes found at mucosal surfaces. The transcriptional and effector programs of ILC strikingly resemble those of the various T-helper (Th) cell fates (that is, Th1, Th2, Th9, Th17, Th22). ILC are involved in protecting the mucosal borders by producing tissue protective factors.

Ischemia-reperfusion injury (IRI) has been implicated in a large array of pathological conditions such as cerebral stroke, myocardial infarction, intestinal ischemia as well as following transplant and cardiovascular surgery. Reperfusion of previously ischemic tissue, while essential for the prevention of irreversible tissue injury, elicits excessive inflammation of the affected tissue. Adjacent to the production of reactive oxygen species, activation of the complement system and increased microvascular permeability, the activation of leukocytes is one of the principle actors in the pathological cascade of inflammatory tissue damage during reperfusion.

It has recently emerged that innate lymphocytes are more diverse than previously appreciated. In addition to natural killer cells, various subsets of innate lymphoid cells are now being characterized. It has become apparent that the transcriptional programs underlying lineage specification and cell fate decisions of innate lymphocytes strikingly resemble those of T cell subsets, suggesting that such transcriptional circuitry was already pre-formed in the evolutionary older innate immune system.

Purpose: Autologous chondrocyte implantation (ACI) is a well-established treatment method for cartilage defects in knees. Age-related grouping was based on expression data of cartilage-specific markers. Specificities of ACI in the different populations were analysed.

Background: We recently established negative pressure wound therapy (NPWT) as a safe postoperative care concept for free muscle flaps; however, the molecular effects of NPWT on free muscle flaps remain elusive. Here we investigated the effects of NPWT on pathological changes associated with ischaemia/reperfusion injury in free flap tissue.
Methods: From July 2008 to September 2010, 30 patients receiving skin-grafted free muscle transfer for defect coverage were randomly assigned to two treatment groups: In one group the skin-grafted free flap was covered by a vacuum dressing (NPWT); in the second group, flaps were covered by conventional petroleum gauze dressings (conv).

Background: Panniculus morbidus is characterized by an edematous, painful hanging abdominal mass, due to laxity and redundancy of the abdominal skin in morbid obesity, particularly after massive weight loss. Panniculectomy, by wedge resection, is a salvage procedure with high satisfaction rates though associated with high complication rates. Here we investigated the effects of perioperative complex decongestive physical therapy (CDP) on outcome and complication rates.

Various approaches to endoscopic carpal tunnel release have been described, including the advantages of the open compared with the endoscopic technique. However recent results suggest that both are equal in terms of outcome and morbidity. The misconception about the potential morbidity and the hope of successful conservative treatment can sometimes delay operative release of the carpal tunnel.

Psychotherapeutic treatments of borderline personality disorder (BPD) often focus on severe behavioral problems. Until now, few techniques have been developed to specifically address low self-esteem in BPD. We developed a 6-session psychoeducative group therapy module to treat low self-esteem in BPD patients.

Recent evidence suggests that the prototypic acute phase reactant C-reactive protein (CRP) is not only a marker but also a potential contributor to inflammatory diseases. CRP belongs to the family of pentraxins and as such consists of five identical non-covalently linked subunits. Contradictory data on the characteristics of CRP as either being pro- or anti-inflammatory may be explained by the existence of two conformations of the protein: the circulating native, pentameric CRP (pCRP) and the monomeric isoform (mCRP), formed as a result of a dissociation process of pCRP.

Alpha thalassaemia myelodysplastic syndrome (ATMDS) is an unusual complication of chronic myeloid malignancy that is associated with a striking red cell phenotype. It represents an acquired form of alpha-thalassaemia that most commonly arises in the context of myelodysplasia. It has recently been shown that this condition occurs in association with somatic mutations of a known X-encoded trans-acting regulator of alpha globin gene (HBA) expression, ATRX.

Background: RhoA and Rho kinase inhibitors overcome the inhibition of axonal regeneration posed by central nervous system (CNS) substrates.
Methods: To investigate if inhibition of the Rho pathway augments the neurite extension that naturally occurs in the peripheral nervous system (PNS) following nerve damage, dorsal root ganglion neurons and Schwann cell co-cultures were incubated with culture medium, C3 fusion toxin, and the Rho kinase (ROCK) inhibitors Y27632 and H1152. The longest neurite per neuron were measured and compared.

RET testing in multiple endocrine neoplasia type 2 for molecular diagnosis is the paradigm for the practice of clinical cancer genetics. However, precise data for distinct mutation-based risk profiles are not available. Here, we survey the clinical profile for one specific genotype as a model, TGC to TGG in codon 634 (C634W).

The purpose of this study was to assess the feasibility of combined keratinocyte and dermal scaffold transplantation performed in a single step for treatment of full-thickness wounds. Cultured autologous keratinocytes were suspended in fibrin and grafted together with decellularised human dermis (Alloderm) in a porcine animal model, involving 10 animals over 4 weeks. Wound healing was evaluated by planimetry.

A 48-year-old patient reported pain in her face and neck. Within 10 years she had undergone three "golden thread lift" suspension procedures, the last one 2 years previously. Skull radiographs showed complete fragmentation of all the implants into small pieces, and a total loss of their vector orientation.

The free fibular flap has been used extensively in facial and extremity long bone reconstruction but has not been presented as a tool for reconstruction following composite hand injuries, in particular for reconstruction of the ulnar border of the hand. We present a case of the use of this flap for reconstruction of such a complex composite hand injury.

The proteins termed TLE in humans, Grg in mice and Groucho in Drosophila constitute a family of transcriptional corepressors. In mammalians there are five different genes encoding an even larger number of proteins. Interactions between these TLE/Grg proteins and an array of transcription factors has been described.

In recent years, the in vivo role of the three members of the RUNX family of transcription factors has in part been elucidated. While Runx1 is essential for mature haematopoiesis and Runx2 for osteochondrogenesis, Runx3 has a function in the nervous system. Translocations and mutations affecting the RUNX1 gene are clearly implicated in leukemogenesis whereas recent data suggest that changed expression levels of RUNX3 may be involved in gastric carcinogenesis.

Decitabine (5-aza-2'-deoxycytidine) acts as a powerful demethylating agent in vitro. Clinically, low-dose decitabine ameliorates cytopenias including induction of trilineage responses in approximately 50% of patients with high-risk myelodysplastic syndrome (MDS). We examined the incidence and kinetics of cytogenetic responses to decitabine in these patients.

In the present study, we have established a technique to create an artificial urethra in a rat animal model by transplantation of in vitro-expanded urothelial cells onto an in vivo-prefabricated tube formation using tissue engineering methods. Urothelial cells from isogenic rats were harvested for culture. A silicon catheter was used to induce a connective tissue capsule-tube formation underneath the abdominal skin.
