Hypoxia inducible factor-1 (HIF-1) is the main transcriptional activator of the cellular response to hypoxia and an important target of anticancer therapy. Phosphorylation by ERK stimulates the transcriptional activity of HIF-1α by inhibiting its CRM1-dependent nuclear export. Here, we demonstrate that phosphorylation by ERK also regulates the association of HIF-1α with a novel interaction partner identified as mortalin (GRP75) which mediates non-genomic involvement of HIF-1α in apoptosis. Mortalin binds specifically to HIF-1α lacking modification by ERK and their complex is localized outside the nucleus...

The human immune deficiency virus type 1 (HIV-1) matrix protein p17 (p17), although devoid of a signal sequence, is released by infected cells and detected in blood and in different organs and tissues even in HIV-1-infected patients undergoing successful combined antiretroviral therapy (cART). Extracellularly, p17 deregulates the function of different cells involved in AIDS pathogenesis. The mechanism of p17 secretion, particularly during HIV-1 latency, still remains to be elucidated. A recent study showed that HIV-1-infected cells can produce Gag without spreading infection in a model of viral latency...

Klebsiella pneumoniae carbapenemases (KPCs) are plasmid encoded carbapenem hydrolyzing enzymes which have the potential to spread widely through gene transfer. The instability of upstream region of blaKPC accelerates emergence of different isoforms. Routine antibiotic susceptibility testing failed to detect KPC producers and some commercial kits have been launched for early identification of KPC producers. Notable among the drugs under development against KPC are mostly derivatives of polymixin; ß-lactamase inhibitor NXL104 with combination of oxyimino cephalosporin as well as with ceftazidime; a novel tricyclic carbapenem, LK-157, potentially useful against class A and class C enzymes; BLI-489-a bicyclic penem derivative; PTK-0796, a tetracycline derivative and ACHN-490...

Children undergoing cancer therapy encounter a diverse spectrum of oral changes that generally are attributed to immunosuppression and bleeding tendencies caused by the therapeutic agents. Therefore, providing oral health instructions and dental rehabilitation before the initiation of cancer therapy is encouraged. In this article, we discuss the general dental management of pediatric patients with cancer actively undergoing cancer therapy, or for whom it is planned. We also describe the dental rehabilitation performed on a child while he was undergoing chemotherapy for neuroblastoma, using an unconventional approach that varied from the standard management protocol used by King Abdulaziz University Hospital...

: Influenza A virus infection can predispose to potentially devastating secondary bacterial infections. Invariant natural killer T (iNKT) cells are unconventional, lipid-reactive T lymphocytes that exert potent immunostimulatory functions. Using a mouse model of postinfluenza invasive secondary pneumococcal infection, we sought to establish whether α-galactosylceramide (α-GalCer [a potent iNKT cell agonist that is currently in clinical development]) could limit bacterial superinfection...

Therapeutic tourism is a recent phenomenon in public health and has had repercussions among people with disabilities. Virtual social networks have enabled people to organize themselves to discover ways and means of seeking unconventional treatments in China. In this context, foreign biotech companies have offered experimental cell treatment therapies. In this work, netnography (conducting ethnographic research online) was conducted on the blogs of 58 people who organized campaigns to carry out treatment in China...

Acquired resistance to conventional and targeted therapies is becoming a major hindrance in cancer management. It is increasingly clear that cancer cells are able to evolve and rewire canonical signalling pathways to their advantage, thus evading cell death and promoting cell invasion. The Axl receptor tyrosine kinase (RTK) has been shown to modulate acquired resistance to EGFR-targeted therapies in both breast and lung cancers. Glioblastoma multiforme (GBM) is a highly infiltrative and invasive form of brain tumour with little response to therapy...

Using the term of progressive multiple sclerosis (PMS), we considered a combined population of persons with secondary progressive MS (SPMS) and primary progressive MS (PPMS). These forms of MS cannot be challenged with efficacy by the licensed therapy. In the last years, several measures of risk estimation were developed for predicting clinical course in MS, but none is specific for the PMS forms. Personalized medicine is a therapeutic approach, based on identifying what might be the best therapy for an individual patient, taking into account the risk profile...

Th17 cells are a heterogeneous population of pro-inflammatory T cells that have been shown to mediate immune responses against intestinal bacteria. Th17 cells are highly plastic and can transdifferentiate to Th1/17 cells or unconventional Th1 cells, which are highly pathogenic in animal models of immune-mediated diseases such as inflammatory bowel diseases. A recent European Journal of Immunology article by Liu et al. (Eur. J. Immunol. 2015. 45:1010-1018) showed, surprisingly, that Th1 cells have a similar plasticity, and could transdifferentiate to Th17 cells...

Novel, tumor-specific drugs are urgently needed for a breakthrough in cancer therapy. Herein, we generated a first-in-class humanized antibody (PRL3-zumab) against PRL-3, an intracellular tumor-associated phosphatase upregulated in multiple human cancers, for unconventional cancer immunotherapies. We focused on gastric cancer (GC), wherein elevated PRL-3 mRNA levels significantly correlated with shortened overall survival of GC patients. PRL-3 protein was overexpressed in 85% of fresh-frozen clinical gastric tumor samples examined but not in patient-matched normal gastric tissues...

CASE SUMMARY: A 6 yr old 45 kg child with severe Cushinoid features was admitted to PICU with probable hypertensive encephalopathy. She presented with increasing headaches, vomiting and seizures becoming unresponsive with a GCS of 3. She was profoundly hypertensive and her cortisol levels were significantly elevated (>2000 nmol/L). Rapid reduction in cortisol levels was required to stabilise her condition prior to surgery. Etomidate is the only readily available intravenous preparation which reliably suppresses adrenocortical function...

Amlodipine, a dihydropyridine calcium channel blocker, is commonly prescribed for the treatment of hypertension. Ingestion of an overdose leads to severe hypotension; if the hypotension is not treated, death may be imminent. Conventional and unconventional interventions were used to treat an adolescent who ingested a life-threatening dose of amlodipine. Severe hypotension resistant to conventional treatment with intralipids and hyperinsulinemia-euglycemia therapy led to the use of plasmapheresis and a pneumatic antishock garment as lifesaving measures...

One of the major transformations in religion in contemporary societies has been the decline of church institutions and their reconstruction within a diverse network of associations, therapies, markets and other unconventional spiritual services. Based on extensive ethnographic fieldwork on religious behaviours and dynamics in sports contexts, and taking the similarities between sport and religion as the point of departure, this paper analyses, reflects on and theorises about the symbolic affinities of these two contemporary social institutions...

The recent study by Hodi et al. published in the Journal of Clinical Oncology has evaluated unconventional response patterns during PD-1 inhibitor therapy using immune-related response criteria (irRC) in comparison with RECIST1.1, which constitutes an important step to further understand immune-related response phenomena. This commentary discusses the key observations in the study in terms of their implications and pitfalls, and describes unmet needs that remain to be addressed. The article also emphasizes the important role of tumor response criteria as a "common language" to describe the results of cancer treatment, and discusses future directions for further advances of the field of immuno-oncology...

Chronic lymphocytic leukemia (CLL) is one of the chronic lymphoproliferative disorders (lymphoid neoplasms). It is characterized by a progressive accumulation of functionally incompetent lymphocytes. Patients with leukemia often seek unconventional treatments not prescribed by hematologist in order to improve their cancer treatment outcome or to manage symptoms. In the present report, a 76-year-old patient was diagnosed with B-cell chronic lymphocytic leukemia (B-CLL). Beetroot-carrot juice is used as a complementary and or/alternative therapy used in conjunction with conventional leukemic treatment (chlorambucil) that has been a standard first-line chemotherapeutic agent for patients with CLL and known to have serious and undesirable side-effects...

B7-H3 (CD276) is an important immune checkpoint member of the B7 and CD28 families. Induced on antigen-presenting cells, B7-H3 plays an important role in the inhibition of T-cell function. Importantly, B7-H3 is highly overexpressed on a wide range of human solid cancers and often correlates with both negative prognosis and poor clinical outcome in patients. Challenges remain to identify the receptor(s) of B7-H3 and thus better elucidate the role of the B7-H3 pathway in immune responses and tumor evasion. With a preferential expression on tumor cells, B7-H3 is an attractive target for cancer immunotherapy...
