Mistranslation errors compromise fitness by wasting resources on nonfunctional proteins. In order to reduce the cost of mistranslations, natural selection chooses the most accurately-translated codons at sites that are particularly important for protein structure and function. We investigated the determinants underlying selection for translational accuracy in several species of plants belonging to three clades: the Brassicaceae, Fabidae and Poaceae. Although signatures of translational selection were found in genes from a wide range of species, the underlying factors varied in nature and intensity...

REVIEW
Or Cohen-Inbar
Pituitary adenomas represent one of the most common types of intracranial tumors, accounting for 10-20% of intracranial tumors. While their macroscopic appearance and anatomical location are relatively homogeneous, pituitary tumors differ widely, generating a variety of neurological and endocrine clinical sequelae. Treatment options include hormone suppressive medical therapy, microscopic or endoscopic neurosurgical resection, radiosurgery, radiation therapy, or observation depending on the biochemical profile and the clinical status of the patient...

For patients with refractory or relapsed Burkitt lymphoma (BL), no standard therapy is available for second-line treatment to date. Nonfunctional caspases-dependent apoptosis pathways, inactivating p53 mutations and pro-survival autophagy prevent activity of conventional chemotherapy. Thus, new drugs bypassing these mechanisms of resistance are required. Here, we investigated the efficacy of the marine natural compound frondoside A (FrA) in eight BL cell lines. FrA revealed cytotoxic effects in all cell lines tested including the multiresistant CA46 cells...

BACKGROUND: Small pancreatic neuroendocrine tumors (PNETs) are a unique subset of pancreatic neoplasms. Chromogranin A (CgA) levels, mitotic rate, and histologic differentiation are often used to characterize PNET behavior. This study evaluates the impact of these factors on survival in patients with PNETs. METHODS: The US National Cancer Data Base (1998-2012) was reviewed for patients with stages I-III, nonfunctional PNETs ≤2 cm. Clinicopathologic characteristics were collected, and univariate and multivariate survival analyses were performed...

BACKGROUND: Some stroke survivors suffer from involuntary movement, which often disturbs upper-limb function, but there are few effective modality options. CASE REPORT: A 70-year-old man presented with persisting right-upper-limb hemiballism due to left thalamic hemorrhage 10 years before. We provided inpatient rehabilitation, including repetitive-facilitative exercise and task-related training, and prescribed clonazepam from day 5 after admission. However, the affected upper limb showed no significant change and remained nonfunctional...

Oligomeric α-synuclein is a key mediator in the pathogenesis of Parkinson's disease (PD) and is mainly cleared by autophagy-lysosomal pathway, whose dysfunction results in the accumulation and cell-to-cell transmission of α-synuclein. In this study, concomitant with the accumulation of iron and oligomeric α-synuclein, higher expression of a lysosomal iron transporter, natural resistance-associated macrophage protein-1 (Nramp1), was observed in microglia in post-mortem striatum of sporadic PD patients. Using Nramp1-deficient macrophage (RAW264...

Clinical nonfunctional pituitary adenomas (NFAs) account for about 40% of pituitary adenomas with almost no clinically relevant hormonal symptoms. Increasing evidence shows that many microRNAs are involved in the development and progression of pituitary adenomas. MicroRNA-524-5p (miR-524-5p) has been reported to cause characteristic alterations in various tumors. However, the functional importance of miR-524-5p in NFAs remains unknown. The aim of this study was to explore the effects of overexpressing miR-524-5p on the proliferation, migration, invasion, and tumorigenicity of pituitary-derived folliculostellate (PDFS) cells using lentiviral transfection...

In contrast to the clear indication for surgical treatment in symptomatic patients with clinically nonfunctioning pituitary adenomas (NFPA), there are no randomized controlled studies comparing therapeutic strategies such as watchful waiting, irradiation, or medical therapy for the management of NFPA after surgery. Further, no medical therapy is currently approved for the treatment of NFPA. In this review, we summarize accumulating data on medications currently approved for secreting pituitary adenomas, used off-label in patients with NFPA...

Primary nonfunction due to thrombosis after pancreas transplant is still the leading cause of nonimmunologic graft failure. Early identification of pancreatic graft arterial thrombus and prompt surgical intervention are effective for rescue of graft perfusion and its associated complications. Here, we report a case of successful surgical thrombectomy of the splenic artery, with particular emphasis on clinical presentation, diagnosis, and surgical technique.

Incidentally detected, sporadic, nonfunctional pancreatic neuroendocrine tumors are increasingly diagnosed on imaging studies performed for unrelated purposes. Although their resection is usually recommended, controversy still exists regarding their optimal management, due to their highly variable and difficult to predict biologic behavior. Recently, several studies and guidelines advocated an expectant management approach in small size, low grade, incidentally diagnosed nonfunctional pancreatic neuroendocrine tumors...

OBJECTIVE: Evaluate the possibility of performing a complex vascular allotransplant of all neck organs including skin. SUMMARY BACKGROUND DATA: There are 2 previous attempts described in the literature, none of them being that complex. The first one is nonfunctional due to chronic rejection, the second one is viable yet considerably limited in complexity (no parathyroids, no skin). METHODS: The allotransplantation was performed simultaneously on 2 adjacent operating rooms, using microsurgical techniques...

Cancer burden rises globally at an alarming pace. According to GLOBOCAN 2012, gastric cancer (GC) is regarded as the fifth most common malignancy in the world. Being twice as high in men as in women, GC is the third leading cause of cancer mortality in both sexes globally. Being labeled as 'junk DNA', pseudogenes were considered as nonfunctional 'trash', which contribute nothing to survival of the organism; therefore, a number of strategies have been developed to circumvent their accidental detection. Recent progresses have confirmed that pseudogenes can have broad and multifaceted spectrum of activities in human cancers in general and GC in particular...
