With the help of the media, there is growing public awareness for the problems associated with rare diseases and their impact on the lives of those affected and their families. Bladder exstrophy-epispadias complex (BEEC) is also a part of the group of rare diseases within the urological field. The German network CURE-Net was founded in 2009 to systematically collect data regarding the epidemiological and molecular causes, and clinical and psychosocial effects of congenital urorectal malformations. With the help of self-help groups a national registry could be established for systematic data retrieval...

This Research Communication describes the study of in vitro biofilm formation of mastitis causing pathogens. Biofilms are communities of bacteria that are attached to a surface and to each other and are embedded in a self-produced matrix of extracellular polymeric substances. Biofilm formation is an important virulence factor that may result in recurrent or persistent udder infections and treatment failure through increased resistance to antibiotics and protection against host defences. In the present study 252 bacterial isolates from milk samples from bovine udder quarters with intramammary infections were examined with Congo Red agar (CRA) method and tube method (TM) for their ability to form biofilms...

The acquisition of self-perpetuating, immunological tolerance specific for graft alloantigens has long been described as the "holy grail" of clinical transplantation. By removing the need for life-long immunosuppression following engraftment, the adverse consequences of immunosuppressive regimens, including chronic infections and malignancy, may be avoided. Furthermore, autoimmune diseases and allergy are, by definition, driven by aberrant immunological responses to ordinarily innocuous antigens. The re-establishment of permanent tolerance towards instigating antigens may, therefore, provide a cure to these common diseases...

To treat cancer, chemotherapy is a key therapeutic approach which is associated with several limitations. This chemotherapeutical agents exhibit multi drug resistance coupled with undesirable side effects. This multidrug resistance is exhibited by tumor cell due to actuation of drug out flow mechanism, programmed cell death and protection mechanisms etc. One of the therapeutic approaches to cure cancer is RNA interference (RNAi). Small interfering RNA (si-RNA) is considered as a major therapeutic tool used to control expression of a particular gene...

Acute lymphoblastic leukemia (ALL) is the most common cancer in children. While survival rates for ALL have improved, central nervous system (CNS) relapse remains a significant cause of treatment failure and treatment-related morbidity. Accordingly, there is a need to identify more efficacious and less toxic CNS-directed leukemia therapies. Extensive research has demonstrated a critical role of the bone marrow (BM) microenvironment in leukemia development, maintenance, and chemoresistance. Moreover, therapies to disrupt mechanisms of BM microenvironment-mediated leukemia survival and chemoresistance represent new, promising approaches to cancer therapy...

A solvent-free induced self-assembly technology for the synthesis of nitrogen-doped ordered mesoporous polymers (N-OMPs) is developed, which is realized by mixing polymer precursors with block copolymer templates, curing at 140-180 °C, and calcination to remove the templates. This synthetic strategy represents a significant advancement in the preparation of functional porous polymers through a fast and scalable yet environmentally friendly route, since no solvents or catalysts are used. The synthesized N-OMPs and their derived catalysts are found to exhibit competitive CO2 capacities (0...

Pan Fu, Xingchen Xiang, Yong Ge, Zhiming Yuan, Xiaomin Hu
Due to the self-produced binary toxins BinA/BinB, some Lysinibacillus sphaericus isolates exhibit high toxicity against mosquito larvae and are utilized in mosquito control programs. Previous whole genome sequencing revealed the presence of a large plasmid pBsph in L. sphaericus C3-41, which contains a 30.5-kb duplication of the genome including the binary toxin genes binA/binB. This was confirmed by Southern blot and qPCR experiments in this study. Mutants of L. sphaericus C3-41, bearing disruptions of the chromosomal-bin (C3-41ΔCab ) or the plasmid-bin (C3-41ΔPab ) and a plasmid cured strain G725, were generated...

A microfluidic chip-like setup consisting of a vascular system of microchannels alternatingly filled with either a resin monomer or a curing agent is used to study the intrinsic physical healing mechanism in self-healing materials. It is observed that, as a prenotched crack propagates across the chip, the resin and curing agent are released from the damaged channels. Subsequently, both the resin and the curing agent wet the surrounding polydimethylsiloxane (PDMS) matrix and spread over the crack banks until the two blobs come in contact, mix, and polymerize through an organometallic cross-linking reaction...

Acute myelogenous leukemia (AML) is initiated and maintained by leukemia stem cells (LSCs). LSCs are therapy-resistant, cause relapse and represent a major obstacle for the cure of AML. Resistance to therapy is often mediated by aberrant tyrosine kinase (TK) activation. These TKs primarily activate downstream signaling via STAT3/STAT5. In this study, we analyzed the potential to therapeutically target aberrant TK signaling and to eliminate LSCs via the multi-TK inhibitor Debio 0617B. Debio 0617B has a unique profile targeting key kinases upstream of STAT3/STAT5 signaling such as JAK, SRC, ABL and class III/V receptor TKs...

Gastric cancer is a major cause of cancer mortality worldwide, with a low survival rate for patients with advanced forms of the disease. Over the recent decades, the investigation of the pathophysiological mechanisms of tumourigenesis has opened promising avenues to understand some of the complexities of cancer treatment. However, tumour regeneration and metastasis impose great difficulty for gastric cancer cure. In recent years, cancer stem cells - a small subset of tumour cells in many cancers - have become a major focus of cancer research...

Articular cartilage (AC) is the weight-bearing tissue in diarthroses. It lacks the capacity for self-healing once there are injuries or diseases due to its avascularity. With the development of tissue engineering, repairing cartilage defects through transplantation of engineered cartilage that closely matches properties of native cartilage has become a new option for curing cartilage diseases. The main hurdle for clinical application of engineered cartilage is how to develop functional cartilage constructs for mass production in a credible way...
