OBJECTIVE: Describes a method of dynamic video-endoscopy of the Eustachian tube (ET) orifice at the nasopharynx to quantitatively represent ET component movements during swallowing using a graphic function and analyze their importance to its opening mechanics. METHODS: This was a pilot study of relational event capture using a polar coordinate system applied to trans-nasal video-endoscopic recordings of the ET during 3 swallows in 5 adults. After topical anesthesia of the nose, a 45° telescope was introduced unilaterally and focused on the ipsilateral ET orifice...

Neuronal damage induced by injury, stroke, or neurodegenerative disease elicits swift immune responses from glial cells, including altered gene expression, directed migration to injury sites, and glial clearance of damaged neurons through phagocytic engulfment. Collectively, these responses hinder further cellular damage, but the mechanisms that underlie these important protective glial reactions are still unclear. Here, we show that the evolutionarily conserved trimeric protein phosphatase 4 (PP4) serine/threonine phosphatase complex is a novel set of factors required for proper glial responses to nerve injury in the adult Drosophila brain...

Type 1 diabetes mellitus (T1DM) is a major subtype of diabetes and is usually diagnosed at a young age with insulin deficiency. The life expectancy of T1DM patients has increased substantially in comparison with that three decades ago due to the availability of exogenous insulin, though it is still shorter than that of healthy people. However, the relation remains unclear between T1DM and dementia as an aging-related disease. We conducted a systematic review of existing literature on T1DM and cognition impairments by carrying out searches in electronic databases Medline, EMBASE, and Google Scholar...

Our central hypothesis is that protection against HIV infection will be powerfully influenced by the magnitude and quality of the B cell response. Although sterilizing immunity, mediated by pre-formed abundant and potent antibodies is the ultimate goal for B cell-targeted HIV vaccine strategies, scenarios that fall short of this may still confer beneficial defenses against viremia and disease progression. We evaluated the impact of sub-sterilizing pre-existing neutralizing antibody on the B cell response to SHIV infection...

Stressful life events occurring in adulthood have been found able to affect mood and behavior, thus increasing the vulnerability for several stress-related psychiatric disorders. However, although there is plenty of clinical data supporting an association between stressful life events in adulthood and an enhanced vulnerability for psychopathology, the underlying molecular mechanisms are still poorly investigated. Thus, in this study we performed peripheral/whole-genome transcriptomic analyses in blood samples obtained from 53 adult subjects characterized for recent stressful life events occurred within the previous 6 months...

Transplantation of stem cells represents an upcoming therapy for many degenerative diseases. For clinical use, transplantation of pluripotent stem cell-derived cells should lead to integration of functional grafts without immune rejection or teratoma formation. Our previous studies showed that the risk of teratoma formation is highly influenced by the immune system of the recipients. In this study, we have observed a higher teratoma formation rate when undifferentiated so-called multipotent adult germline stem cells (maGSCs) were transplanted into the heart of T, B, and natural killer (NK) cell-deficient RAG2(-/-)γc(-/-) mice than in RAG2(-/-) mice, which still have NK cells...

BACKGROUND: The assessment of cardiac risk in contemporary liver transplantation (LT) has required more sensitive testing for the detection of occult coronary artery disease as well as microvascular and functional cardiac abnormalities. Because dobutamine stress perfusion echocardiography provides an assessment of both regional systolic and diastolic function as well as microvascular perfusion (MVP), we sought to examine its incremental value in this setting. METHODS AND RESULTS: We evaluated the predictive value of dobutamine stress perfusion echocardiography in 296 adult patients with end-stage liver disease and preserved systolic function who underwent LT between 2008 and 2014...

BACKGROUND: Patients with relapsed diffuse large B-cell lymphoma (DLBCL) not eligible for autologous stem cell transplantation (ASCT) or having relapse after ASCT have a low likelihood of cure. Single-drug maintenance after salvage therapy might be an attractive strategy to prolong survival in these patients. Lenalidomide is a suitable candidate for long-lasting maintenance as it is an oral drug, active against DLBCL that can be taken for years with an acceptable toxicity profile. We designed a study to investigate safety and efficacy of lenalidomide maintenance in patients with chemosensitive relapse of DLBCL not eligible for ASCT or having relapse after ASCT...

OBJECTIVES: Late-life depression often has a chronic course, with debilitating effects on functioning and quality of life; there is still no consensus on important risk factors explaining this chronicity. Cross-sectional studies have shown that childhood abuse is associated with late-life depression, and in longitudinal studies with chronicity of depression in younger adults. We aim to investigate the impact of childhood abuse on the course of late-life depression. DESIGN: Two-year longitudinal cohort study...

Adult hippocampal neurogenesis is essential for learning and memory, and its dysfunction is involved in neurodegenerative diseases. However, the molecular mechanisms underlying adult hippocampal neurogenesis are still largely unknown. Our previous studies indicated that the transcription factor Brn4 was upregulated and promoted neuronal differentiation of neural stem cells (NSCs) in the surgically denervated hippocampus in rats. In this study, we use high-throughput RNA sequencing to explore the molecular mechanisms underlying the enhancement of adult hippocampal neurogenesis induced by lentivirus-mediated Brn4 overexpression in vivo...

BACKGROUND: Hepatic epithelioid hemangioendothelioma (HEHE) is a rare vascular tumor which has an intermediate aggressive behavior. Although the value of liver transplantation (LT) is well established, its place in the management of HEHE is still unclear. The aim of this study is to confirm, based on a very large patient cohort, the value of LT in the management of HEHE and to identify risk factors for post-LT recurrence. METHODS: The outcome of 149 transplant recipients with HEHE recorded in the European Liver Transplant Registry during the period November 1984 to May 2014 was analyzed...

Tuberculosis, commonly known as TB, is the second most fatal infectious disease after AIDS, caused by bacterium called Mycobacterium tuberculosis. Prolonged treatment, high pill burden, low compliance, and stiff administration schedules are factors that are responsible for emergence of MDR and XDR cases of tuberculosis. Till date, only BCG vaccine is available which is ineffective against adult pulmonary TB, which is the most common form of disease. Various unique antibodies have been developed to overcome drug resistance, reduce the treatment regimen, and elevate the compliance to treatment...

BACKGROUND AND AIM: Celiac disease (CD) is a common gluten-related disorder, whose only treatment is a gluten-free diet (GFD). Since a unique view on psychological consequences of a GFD still lacks, our aim was to assess the quality of life (QoL) and the depression state in symptomatic CD patients after GFD. Socio-demographic features were considered. PATIENTS AND METHODS: 210 adult CD patients were recruited and divided into 3 groups : 70 newly diagnosed patients (​Group A​),70 patients who have been on GFD for 6-12 months (​Group B​), and 70 patients who have been on GFD for more than 12 months (​Group C​)...

In this manuscript, we report an exceptional observation study of a young woman suffering from an autoimmune syndrome induced by adjuvants (ASIA). Until today only seven cases of adult-onset Still's disease (AOSD) induced by breast implants have been published. This may be due to the fact that this illness itself is very rare; however, the reason might also be that the community is not sensitized to the case-specific symptoms. Within this article, we show for the first time highly detailed diagnostic test procedures such as PET-CT scans and specific histological staining of the breast tissue, displaying proinflammatory macrophages that are a well-known activator and booster of autoimmune diseases...

There is substantial evidence suggesting that Western and non-Western caregivers of patients with Alzheimer's disease have different caregiving experiences depending on the cultural values they adopt. Although family-centered constructs such as familism and filial piety have taken some attention, there is still a paucity of research on how cultural values and norms shape caregiving appraisals, coping strategies, and formal service use specifically in Eastern-oriented contexts. The aim of this study was to investigate Turkish adult children caregivers' perceptions of Alzheimer's disease and caregiving experience...

Adult stem cells uphold a delicate balance between quiescent and active states, a deregulation of which can lead to age-associated diseases such as cancer. In Drosophila, intestinal stem cell (ISC) proliferation is tightly regulated and mis-regulation is detrimental to intestinal homeostasis. Various factors are known to govern ISC behavior; however, transcriptional changes in ISCs during aging are still unclear. RNA sequencing of young and old ISCs newly identified Nipped-A, a subunit of histone acetyltransferase complexes, as a regulator of ISC proliferation that is upregulated in old ISCs...
