D Schneider, M Hirsch
Acute calcific tendinopathy is one of the manifestations of hydroxyapatite crystal deposition disease. While it is more frequent in the shoulder, it has been described in virtually all areas of the body, but rarely in the muscles of the hand. Its etiopathogenesis is not yet fully understood and despite being a fairly frequent condition, it is commonly misdiagnosed. The onset of the disease is usually acute and resolves spontaneously. Acute calcific tendinitis of the interosseous tendons of the hand is an uncommon site of a frequent condition...

Osteonecrosis of the jaw (ONJ) is a rare adverse event of antiresorptive drugs such as bisphosphonates (BP) and denosumab (DMAb). The diagnosis of ONJ is considered in cases where exposed bone in the maxillofacial region does not heal within 8 weeks in a patient previously treated with an antiresorptive agent. In patients with osteoporosis, ONJ is reported as a very rare adverse event while in oncologic patients with bone metastases or malignant hypercalcemia the incidence is significantly higher (up to the 1-10% of the patients)...

The bioactivities of boxthron fruits, a source of oriental medicine, are known, while phytochemical studies of the boxthorn stem are rare. In this study, the stem extract of boxthorn (Lycium chinense Miller) and its sub-fractions were evaluated for their effects on nitric oxide (NO) inhibition and procollagen type I peptide (PIP) synthesis. A phenolic amide isolated from the stem extract was also assayed for these effects. The compound, N-trans-feruloyltyramine, was identified by (1)H, (13)C, and 2D-nuclear magnetic resonance analysis...

Chronic kidney disease (CKD) exacerbating vascular disease poses a major challenge to nephrology. Surgically placed vascular fistulas, as an aid to hemodialysis prior to kidney transplant, have extended many lives, while post-surgical restenosis closure of the fistula by smooth muscle cells affects many lives. When post-surgical restenosis is developed, palliative measures are almost always surgical: there are no effective drug treatments. In this study, we offer a testable hypothesis that effects of CKD on widely distributed vascular diseases and the phenomenon of fistula restenosis are both driven by the pathologic creation of non-dividing smooth muscle cells via asymmetric division of exponentially increasing metakaryotic stem cells...

Pancreatic neuroendocrine tumors (pNETs) are rare neoplasms representing less than 2% of all pancreatic malignancies. The PI3K-AKT-mTOR pathway is often deregulated in pNETs and seems to play a key role in tumorigenesis. Everolimus, an inhibitor of the mTOR pathway, has demonstrated efficacy in the treatment of pNETs. Nevertheless de novo or acquired drug resistance is responsible for disease progression and represents a major obstacle to overcome by clinicians. Blocking the PI3K/AKT/mTOR pathway may cover the supposed main mechanisms of resistance to everolimus...

Objective Posttransplant lymphoproliferative disorder (PTLD) is a unifying term for a spectrum of lymphoid expansion entities brought about by immunosuppression and is strongly associated with Epstein-Barr virus (EBV). Otolaryngological findings tend to present early in the clinical course; therefore, disease awareness among otolaryngologists is of utmost importance. This review synthesizes the body of literature pertaining to PTLD involving the head and neck, summarizes contemporary management, and highlights areas for future research...

High-profile genomic variation projects like the 1000 Genomes project or the Exome Aggregation Consortium, are generating a wealth of human genomic variation knowledge which can be used as an essential reference for identifying disease-causing genotypes. However, accessing these data, contrasting the various studies and integrating those data in downstream analyses remains cumbersome. The Human Genome Variation Archive (HGVA) tackles these challenges and facilitates access to genomic data for key reference projects in a clean, fast and integrated fashion...

Myotonic Dystrophy Type 1 (DM1) is a rare genetic disease caused by expansion of CTG trinucleotide repeats ((CTG)exp) in the 3' untranslated region of the DMPK gene. The repeat transcripts sequester the RNA binding protein Muscleblind-like protein 1 (MBNL1) and hamper its normal function in pre-mRNA splicing. Overexpressing exogenous MBNL1 in the DM1 mouse model has been shown to rescue the splicing defects and reverse myotonia. Although a viable therapeutic strategy, pharmacological modulators of MBNL1 expression have not been identified...

Background: Large cell neuroendocrine carcinoma of the lung (LCNEC) is a rare disease with poor prognosis and limited treatment options. Neuroendocrine tumors frequently show overactivation of the mTOR pathway. Based on the good activity of the mTOR inhibitor everolimus in different types of neuroendocrine tumors and the results of a previous phase I trial we evaluated the efficacy and safety of everolimus in combination with carboplatin and paclitaxel as upfront treatment for patients with advanced LCNEC...

Jordan M Horowitz, Rahul V Kulkarni
The intrinsic stochasticity of gene expression can give rise to large fluctuations and rare events that drive phenotypic variation in a population of genetically identical cells. Characterizing the fluctuations that give rise to such rare events motivates the analysis of large deviations in stochastic models of gene expression. Recent developments in non-equilibrium statistical mechanics have led to a framework for analyzing Markovian processes conditioned on rare events and for representing such processes by conditioning-free driven Markovian processes...

A 4 mo old intact male kitten was presented for chronic regurgitation and failure to thrive after weaning to dry food. Esophageal dilatation and severe diffuse proliferative lesions of the esophageal mucosa were found via radiography and esophagoscopy, respectively. Histopathologic examination revealed severe, chronic, diffuse, hyperplastic eosinophilic and mastocytic esophagitis. Eosinophilic infiltrates were prominent, with a mean of 29.8 eosinophils per high power field, supportive of eosinophilic esophagitis (EoE)...

Chronic idiopathic neutropenia (CIN) is an acquired disorder of granulopoiesis characterized by female predominance and mostly uncomplicated course. Crucial to CIN pathophysiology is the presence of activated T lymphocytes with myelosuppressive properties in both peripheral blood (PB) and bone marrow (BM). We systematically profiled the T cell receptor beta chain (TRB) gene repertoire in CD8(+) cells of 34 CIN patients through subcloning/Sanger sequencing analysis of TRBV-TRBD-TRBJ gene rearrangements. Remarkable repertoire skewing and oligoclonality were observed, along with shared clonotypes between different patients, alluding to antigen selection...

Qinghui Cheng, Wei Qiang
Solid-state nuclear magnetic resonance (ssNMR) spectroscopy has been widely applied to characterize the high-resolution structures of β-amyloid (Aβ) fibrils. While these structures provide crucial molecular insights on the deposition of amyloid plaques in Alzheimer's diseases (AD), ssNMR structures have been rarely used so far as basis for designing inhibitors. It remains a challenge because the ssNMR-based Aβ fibrils structures were usually obtained with sparsely-isotope-labeled peptides with limited experimental constraints, where the structural models, especially the side-chain coordinates showed restricted precision...

Tetanus, an almost forgotten but serious disease Tetanus is the systemic consequence of a local infection with Clostridium tetani, that produces toxin which spreads in the systemic circulation. In developed countries, it is extremely rare. Women born before 1950 are a group at risk due to lower prevalence of immunisation. This report describes a case of tetanus. The patient is a previously healthy 82-year-old woman. She presented to primary care with a complaint of stiffness in the neck and jaw. A physical exam and basic laboratory tests were normal apart from a slightly increased blood pressure...

Gastric cancer is one of the leading causes of cancer-related deaths worldwide. Despite the advanced surgical resection techniques and anticancer drugs currently available to treat early stage gastric cancer, the prognosis of patients with gastric cancer remains poor. The epithelial to mesenchymal transition (EMT) is an important process for the initiation of tumorigenesis. Recent studies suggested that reactive oxygen species (ROS) can promote cell migration and invasion. Thus, an imbalance of redox homeostasis can result in cancer cells exhibiting EMT properties...

CC-chemokine receptor 5 serves as the coreceptor for the HIV-1 R5 strains, which are responsible for the majority of HIV transmissions. A deletion of 32 nucleotides in the gene encoding this receptor (termed CCR5-Δ32) leads to the suppression of CC-chemokine receptor 5 presentation at the cell surface, thus impeding process of HIV entry into the cell. Individuals homozygous for the CCR5-Δ32 allele are resistant to infection with HIV-1 R5 strains, and are extremely rare among HIV-1-infected individuals. We have described a case of person homozygous for CCR5-Δ32, who was infected with subtype B HIV-1...

Hepatitis A virus (HAV) is a small RNA, non-enveloped agent predominantly transmitted via the fecal/oral route through person-to-person contact or contaminated food and water. The mean incubation period is 28 days (range: 15-50). Acute hepatitis A is always self-limited and very rarely fatal. Moreover, it never progresses to chronicity. Acutely infected persons are most likely to transmit HAV before the onset of jaundice, when viral particle concentration in stool is highest.
