Protein restriction cycles reduce IGF‐1 and phosphorylated Tau, and improve behavioral performance in an Alzheimer's disease mouse model
Summary
In laboratory animals Calorie Restriction (CR) protects against aging, oxidative stress and neurodegenerative pathologies. Reduced levels of growth hormone and IGF‐1, which mediate some of the protective effects of CR, can also extend longevity and protect against age‐related diseases in rodents and humans. However, severely restricted diets are difficult to maintain and are associated with chronically low weight and other major side effects. Here, we show that four months of periodic protein restriction cycles (PRC) with supplementation of non‐essential amino acids in mice already displaying significant cogn...

Peritoneal adhesion index (PAI): proposal of a score for the ¿ignored iceberg¿ of medicine and surgery
Peritoneal adhesions describe a condition in which pathological bonds form between the omentum, the small and large bowels, the abdominal wall, and other intra-abdominal organs. Different classification systems have been proposed, but they do not resolve the underlying problem of ambiguity in the quantification and definition of adhesions. We therefore propose a standardized classification system of adhesions to universalize their definition based on the macroscopic appearance of adhesions and their diffusion to different regions of the abdomen. By scoring with these criteria, the peritoneal adhesion index (PAI) can range ...

Wide-field Imaging of the Retina
Abstract: The retinal periphery is the site of pathology in several eye diseases. Imaging of the peripheral retina offers a way to diagnose, monitor, and evaluate responses to the treatment of these conditions. Traditional fundus cameras have offered a 30- to 50-degree field of view. Recent technology has advanced to provide up to a 200-degree field of view. The utility of this technology in clinical practice continues to be investigated; wide-field color photography, autofluorescence imaging, and fluorescein angiography have been used for imaging peripheral retinal disease. Due to the limitations of this imaging technolog...

Clinicopathological and prognostic significance of HIF-1α and HIF-2α expression in small cell lung cancer.
Abstract
Previous work from our laboratory has demonstrated that urokinase plasminogen activator receptor (uPAR) may be a potential stem-like cell marker in SCLC. Hypoxia inducible factor (HIF) has been shown to transcriptionally regulate uPAR expression. Therefore, the aim of this study was to evaluate the relationship between HIF-1α/HIF-2α and uPAR expression, and to investigate the role of HIF-1α/HIF-2α in the clinical pathology and prognosis of patients with SCLC. Immunohistochemical analysis showed that HIF-1α/HIF-2α staining was mainly present in the nuclei of cancer cells. HIF-1α-positive cells were d...

Impact of single nucleotide polymorphism in tumor necrosis factor-α gene 308G/A in Egyptian asthmatic children and wheezing infants.
Abstract
Bronchial asthma is a common disease with multiple determinants that include genetic variation. Although tumor necrosis factor alpha (TNF-α) is a major pro-inflammatory cytokine, the functions of genetic polymorphisms in this cytokine has not been thoroughly examined in the context of asthma pathology. Therefore, we aimed to investigate whether single nucleotide polymorphism (SNP) in TNF-α is associated with asthma and wheezing and whether the association is related to the severity of the disease and other epidemiological factors. Frequencies of TNF-α-308G/A polymorphism were compared in 100 asthmatic c...

Interobserver variability in grading transbronchial lung biopsies after lung transplantation.
CONCLUSION: These results expand upon previous reports of interobserver variability in grading transbronchial biopsies after lung transplantation. Given the variability in the grading transbronchial biopsies, we advocate further education of the histopathologic findings in lung transplant biopsies as well as revisiting the current criteria for grading transbronchial biopsies in order to improve concordance among lung transplant pathologists.

The concept of the onychodermis (specialized nail mesenchyme): an embryological assessment and a comparative analysis with the hair follicle
ConclusionsThe concept of the onychodermis is equally valid in the developing nail organ where it is also defined by its expression for CD10. Its function may be related to the anchorage of the overlying nail bed but may also involve a more dynamic role in the induction of hard keratins in the latter, contributing to the formation of the nail plate.

Does the calcification of adamantinomatous craniopharyngioma resemble the calcium deposition of osteogensis/odontogenesis?
ConclusionsOur study indicated, for the first time, that osteogenic factor Bmp2 may play an important role in the calcification of ACP via autocrine or paracrine mechanisms. Given the presence of osteogenic markers (Runx2 and Osterix), CP cells could differentiate into an osteoblast‐like lineage, and the process of CP calcification resembles that which occurs in osteogenesis/odontogenesis.© 2012 Blackwell Publishing Ltd

Metastatic urachal carcinoma in bronchial brush cytology
We present a case of metastatic urachal adenocarcinoma in bronchial brushings and review the use of immunohistochemistry in its diagnosis. A 47-year-old female was seen initially in 2007 with adenocarcinoma of the bladder dome for which she underwent partial cystectomy. She presented in 2011 with a left lung mass and mediastinal adenopathy. Bronchoscopy showed an endobronchial lesion from which brushings were obtained. These showed numerous groups of columnar cells with medium sized nuclei and abundant cytoplasm. The cells were positive for CK20 and CDX2 and negative for CK7. The cytomorphological findings were similar to ...

Monoclonal antibodies selective for α‐synuclein oligomers/protofibrils recognize brain pathology in Lewy body disorders and transgenic mice expressing the disease‐causing A30P mutation
Abstract
Inclusions of intraneuronal alpha‐synuclein (α‐synuclein) can be detected in brains from patients with Parkinson's disease (PD) and dementia with Lewy bodies (DLB). The aggregation of α‐synuclein is a central feature of the disease pathogenesis. Among the different α‐synuclein species, large oligomers/protofibrils have particular neurotoxic properties and should therefore be suitable as both therapeutic and diagnostic targets. Two monoclonal antibodies, mAb38F and mAb38E2, with high affinity and strong selectivity for large α‐synuclein oligomers were generated. These antibodies, which do not bind amy...

Epigenetic Regulation of the X‐Linked Tumor Suppressors BEX1 and LDOC1 in Oral Squamous Cell Carcinoma
Abstract
The strong associations between oral squamous cell carcinoma (OSCC) and dietary habits such as Alcohol consumption (A), Betel quid chewing (B) and Cigarette smoking (C) and its predominance in men have been well‐documented; however, systemic analysis of OSCC is limited. Our study applied high‐throughput screening methods to identify causative epigenetic targets in a cohort of men with ABC‐associated OSCC. We identified BEX1 and LDOC1 as two epigenetically silenced X‐linked tumour suppressors and demonstrated a functional link between the transcription of BEX1 and LDOC1 and promoter hypermethylation. Methyl...

Involvement of the cholinergic basal forebrain nuclei in spinocerebellar ataxia type 2 (SCA2)
ConclusionsThe findings of the present study (1) indicate that the mutation and pathological process underlying SCA2 play a causative role for this severe degeneration of the cholinergic basal forebrain nuclei and (2) may suggest that degeneration of the cholinergic basal forebrain nuclei per se is not sufficient to cause profound and global dementia detrimental to everyday practice and activities of daily living.

Strain differences in pleural mesothelial cell reactions induced by potassium octatitanate fibers (TISMO) infused directly into the thoracic cavity.
Abstract
Although we have previously reported that the fiber-shaped TISMO, morphologically similar to asbestos, can induce a severe mesothelial reaction in A/J mice, it is important to clarify any strain differences. In the present study, female A/J, C3H/HeN, ICR and C57BL/6 mice were therefore employed as test strains. At the beginning of the experiment, all mice underwent a left thoracotomy and direct administration of 3mg of TISMO particles suspended in 0.2ml saline into the left thorax. The experiment was terminated after 21 weeks and all groups were sacrificed and the mesothelium and main organs were examined ...

Mechanistic Insights into Self-Reinforcing Processes Driving Abnormal Histogenesis During the Development of Pancreatic Cancer.
Abstract
Pancreatic ductal adenocarcinoma, one of the most feared lethal and painful diseases, is increasing in incidence. The poor prognosis of pancreatic ductal adenocarcinoma-affected patients primarily is owing to our inability to develop effective therapies. Mechanistic studies of genetic, epigenetic, and cell-to-cell signaling events are providing clues to molecular pathways that can be targeted in an attempt to cure this disease. The current review article seeks to draw inferences from available mechanistic knowledge to build a theoretical framework that can facilitate these approaches. This conceptual model...

Application of Interleukin-22 Mediates Protection in Experimental Acetaminophen-Induced Acute Liver Injury.
Abstract
Acetaminophen (APAP, paracetamol)-induced hepatotoxicity, although treatable by timely application of N-acetylcysteine, can be fatal. Because it is among the common causes of acute liver failure in intensive care units and in light of its gradually increasing incidence, the need for novel therapeutic strategies aimed at severe intoxication is apparent. Recently, it has been shown that IL-22, a STAT3-activating cytokine, has the capability to mediate liver protection. Herein, the protective potential of IL-22 in murine APAP-induced hepatotoxicity was assessed. Intravenous administration of prophylactic IL-2...

ABCA1 influences neuroinflammation and neuronal death.
Abstract
ATP-binding cassette transporter A1 (ABCA1) mediates cellular cholesterol efflux in the brain and influences whole brain cholesterol homeostasis. Activation of liver X receptors (LXRs), transcription factors that increase the expression of cholesterol transport genes including ABCA1, reduces neuroinflammation and pathology in neurodegenerative animal models suggesting that in addition to its involvement in cholesterol transport, ABCA1 may play a role in modulating the inflammatory response in the brain. We investigated the cell-type specific role of ABCA1 in neuroinflammation in vivo using mice specificall...

Targeting dysregulation of brain iron homeostasis in Parkinson's disease by iron chelators.
Abstract
Brain iron accumulation has been implicated in a host of chronic neurological diseases including Parkinson's disease (PD). The elevated iron levels observed in the substantia nigra of PD subjects have been suggested to incite the generation of reactive oxygen species and intracellular α-synuclein aggregation, terminating in the oxidative neuronal destruction of this brain area. Thus, elucidation of the molecular mechanisms involved in iron dysregulation and oxidative stress-induced neurodegeneration is crucial step in deciphering PD pathology and in developing novel iron complexing compounds, aimed at res...

Prevention of Needle-Tract Seeding by Two-Step Freezing after Lung Cancer Biopsy.
Abstract
Fine-needle aspiration biopsy is a method to detect malignancy for undetermined pulmonary nodules, but has the potential to spread malignant cells from the tumor to the pleural cavity or chest wall. We developed a two-step freezing method to avoid needle-tract seeding, by use of percutaneous cryoablation after biopsy but before the biopsy needle was removed. A man aged 72 years was admitted because of a large mass in right upper lobe. After biopsy, the patient underwent surgery. Pathological assessment of the resected tumor showed that tissue around the biopsy probe and cryoprobe had been killed before ne...

Initial Assessment of the Pathogenic Mechanisms of the Recently Identified Alzheimer Risk Loci
Summary
Recent genome wide association studies have identified CLU, CR1, ABCA7 BIN1, PICALM and MS4A6A/MS4A6E in addition to the long established APOE, as loci for Alzheimer's disease. We have systematically examined each of these loci to assess whether common coding variability contributes to the risk of disease. We have also assessed the regional expression of all the genes in the brain and whether there is evidence of an eQTL explaining the risk. In agreement with other studies we find that coding variability may explain the ABCA7 association, but common coding variability does not explain any of the other loci. We were...

The Aging Eye: Common Degenerative Mechanisms Between the Alzheimer's Brain and Retinal Disease [Review]
Alzheimer's disease (AD) is a common, incurable, and progressive dementia, characterized by loss of learning and memory and the neuropathologic accumulation of amyloid plaques and neurofibrillary tangles in the brain. A number of similarities between AD pathology and several distinct retinal degenerations have been described, particularly with respect to either glaucoma or age-related macular degeneration (AMD), each a leading cause of vision loss and blindness worldwide. Although comparisons between these diseases may provide important new insights into their pathogenic mechanisms, glaucoma and AMD result in markedly diff...

Genistein, a natural product derived from soybeans, ameliorates polyglutamine‐mediated motor neuron disease
Abstract
Spinal and bulbar muscular atrophy (SBMA) is an inherited motor neuron disease caused by the expansion of a polyglutamine (polyQ) tract within the androgen receptor (AR) gene. The pathologic features of SBMA are motor neuron loss in the spinal cord and brainstem and diffuse nuclear accumulation and nuclear inclusions of mutant AR in residual motor neurons and certain visceral organs. AR‐associated coregulator 70 (ARA70) was the first co‐regulator of AR to be identified, and it has been shown to interact with AR and increase its protein stability. Here, we report that genistein, an isoflavone found in soy, disr...

Stevens‐Johnson Syndrome associated with mogamulizumab treatment of Adult T‐cell leukemia/lymphoma
We report an ATL patient suffering from Stevens‐Johnson Syndrome (SJS) during mogamulizumab (humanized anti‐CCR4 monoclonal antibody) treatment. There was a durable significant reduction of the CD4+CD25highFOXP3+ regulatory T (Treg) cell subset in the patient′s PBMC, and the affected inflamed skin almost completely lacked FOXP3‐positive cells. This implies an association between reduction of the Treg subset by mogamulizimab and occurrence of SJS. The present case should contribute not only to our understanding of human pathology resulting from therapeutic depletion of Treg cells, but also alert us to the possibil...

Manganese toxicity in the CNS: the glutamine/glutamate‐γ‐aminobutyric acid cycle
Abstract
Manganese (Mn) is an essential trace element that is required for maintaining proper function and regulation of numerous biochemical and cellular reactions. Despite its essentiality, at excessive levels Mn is toxic to the CNS. Increased accumulation of Mn in specific brain regions, such as the substantia nigra, globus pallidus and striatum, triggers neurotoxicity resulting in a neurological brain disorder, termed manganism. Mn has been also implicated in the pathophysiology of several other neurodegenerative diseases. Its toxicity is associated with disruption of the glutamine (Gln)/glutamate (Glu)‐γ‐aminobut...

Quality assessment metrics for whole genome gene expression profiling of paraffin embedded samples
Conclusion:
Proper assessment of array quality within a research study is crucial for controlling unwanted variability in the data. The metrics proposed in this paper have direct biological interpretations and can be used to identify arrays that should either be removed from analysis all together or down-weighted to reduce their influence in downstream analyses.

ProEx C as an adjunct marker to improve cytological detection of urothelial carcinoma in urinary specimens
CONCLUSIONSProEx C stain is a useful adjunct test to urine cytologic analysis, even in specimens with limited cellularity. In urinary smears, this test is most useful in stratification of the “atypical” diagnoses into benign and malignant subsets. To the authors' knowledge, this is the first study of ProEx C application in urine cytology as an adjunct marker for detection of urothelial carcinoma.

Tips and tricks to avoid periprocedural neurological complications in carotid artery stenting.
Abstract
Execution of carotid artery stenting (CAS) requires not only excellent manual dexterity, and a high level of competence, but also in-depth knowledge of the carotid pathology, of the materials available on the market and of the different techniques to apply in given situations. Actually each individual moment of the procedure can be determining for the final result. This review describes each individual step of CAS, including arterial access, carotid engagement, pre-dilatation, the characteristics and use of cerebral protection devices, stent selection and deployment, and post-dilatation. Technical notes an...
