TLR2 recognizes cell wall components of Staphylococcus aureus, which colonizes >90% of atopic eczematous skin lesions. The regulatory mechanisms of TLR2 signaling in the skin remain unclear. Allergin-1, an inhibitory immunoglobulin-like receptor containing an ITIM, is expressed on mast cells (MCs) and inhibits IgE-mediated anaphylaxis in mice. Here, we show that Allergin-1 inhibits TLR2-mediated activation of, and inflammatory cytokine production by, MCs in vitro Compared with wild-type mice, Allergin-1-deficient mice showed enhanced ear swelling with enhanced collagen deposition and greater Ly6G(+) neutrophil recruitment after intra-dermal injection of Pam2CSK4 into pinnae...

The extreme drought tolerance of the resurrection fern is in part the result of the dorsal scales that assist in water distribution and controlled desiccation. We studied the effect of peltate scales on water uptake and loss of the desiccation-tolerant epiphytic fern Pleopeltis polypodioides using optical and FTIR microscopy and staining with calcofluor, solophenyl flavine7GFE, and Ruthenium Red. We provide information on structure, property, and function of the scales by measuring water uptake and dehydration, contact angles, and metabolic activity...

BACKGROUND AND AIMS: Nutritional status (NS) is not routinely assessed in HF. We sought to evaluate whether NS may be additive to a comprehensive pre-discharge evaluation based on a clinical score that includes BMI (MAGGIC) and on an index of functional capacity (six minute walking test, 6mWT) in HF patients. METHODS AND RESULTS: The CONUT (Controlling Nutritional Status) score (including serum albumin level, total cholesterol and lymphocyte count) was computed in 466 consecutive patients (mean age 61 ± 11 years, NYHA class 2...

Different surgical solutions have been proposed for reconstruction of the auricle following loss of the pinna through traumatic injury or neoplastic disease or in patients with congenital defects. Surgical treatment may involve the insertion of an autogenous rib cartilage framework or the use of a porous polymer material inserted into an expanded postauricular flap. Reconstruction with rib cartilage has yielded good results but requires more than one surgical step, and adverse events can occur both at the donor and at the acceptor site; cases of prosthesis rejection have also been described following application of the polymeric prosthesis...

A new approach is proposed for statistically analysis of laser speckle signals emerged from a living biological tissue based on eigen-decomposition to separate the dynamic speckle signals due to moving blood cells from the static speckle signals due to static tissue components, upon which to achieve angiography of the interrogated tissue in vivo. The proposed approach is tested by imaging mouse ear pinna in vivo, demonstrating its capability of providing detailed microvascular networks with high contrast, and high temporal and spatial resolutions...

BACKGROUND: Biliopancreatic diversion (BPD) is a bariatric technique burdened, in some instances, by clinical evidence of malabsorption and malnutrition, and by intractable diarrhea. OBJECTIVE: The objective of this study was to assess metabolic and nutritional effects on patients undergoing BPD and BPD plus revisional surgery because of side effects. METHODS: Thirty-five consecutive BPD patients underwent revisional surgery (elongation of the common limb from 50 to 200 cm and reduction of the gastric pouch from 500 to 40 ml) after a median 48-month period [48...

PURPOSE: The aim of this study was to help with the process of selecting patients with advanced ovarian cancer to undergo cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) by analyzing outcome data at distinct clinical time points reflecting the natural history of the disease. METHODS: In a retrospective Italian multicenter study investigating patients with advanced ovarian cancer who underwent CRS plus HIPEC between 1998 and 2014, we analyzed data for consecutive patients at eight treatment time points: primary debulking surgery (PDS); interval debulking surgery after partial response, after no response, and after a pathologic complete response to neoadjuvant chemotherapy; first recurrence with a progression-free interval >12, <12 months, or >12 months in patients who underwent further chemotherapy before CRS and HIPEC; and patients who underwent two or more CRS procedures and chemotherapy lines before CRS and HIPEC...

We investigated the familiar phenomenon of the uncanny feeling that represented people in frontal pose invariably appear to "face you" from wherever you stand. We deploy two different methods. The stimuli include the conventional one-a flat portrait rocking back and forth about a vertical axis-augmented with two novel variations. In one alternative, the portrait frame rotates whereas the actual portrait stays motionless and fronto-parallel; in the other, we replace the (flat!) portrait with a volumetric object...

Housing and feeding practices of wild birds for conservation management of biodiversity or restocking play a crucial role in determining the survival rates of animals when released into nature. Failure in coping with the environment might be one of the main flaws captive animals can experience when put into natural habitat. The present investigation aimed at exploring feeding habits and related morphometric traits of gizzard with respective content from wild partridges in comparison with captive ones. A total of 52 hunted wild Sardinian adult partridges (Alectoris barbara barbara Bonnaterre, 1790) were used...

Congenital facial palsy (CFP) is clinically defined as facial palsy of the seventh cranial nerve which is present at birth or shortly thereafter. It is generally considered to be either developmental or acquired in origin. Facial palsy of developmental origin is associated with other anomalies including those of pinna and external auditory canal, which range from mild defects to severe microtia and atresia. We report a 2-day-old male newborn that had right CFP with bilateral anotia and atresia of external auditory canals which is rare...

BACKGROUND: Treatment of patients with chronic hepatitis C who failed the triple therapy with first generation of protease inhibitors is not still defined. The combined use of sofosbuvir (SOF) and daclatasvir (DCV) seems to be promising due to higher genetic barrier, good tolerance and effectiveness. METHODS: We described the treatment with this drug combination in a real-life cohort of 20 cirrhotic patients with genotype 1 who failed the triple therapy. RESULTS: 18 of them (90%) with Child-Pugh A, 11 (55%) with genotype 1a, 17 (85%) with more than 1 and 8 (40%) with more than 2 previous failed treatment; all patients had at baseline NS3 resistance-associated variants related to triple therapy failure...

BACKGROUND: In treating pancreatic ductal adenocarcinoma (PDAC), age does not represent a contraindication to surgery, even if aging is known to increase postoperative mortality and morbidity. Furthermore, long-term outcome remains poor and there is much debate on whether to operate or not in elderly patients. The aim of this study was to provide a general framework to evaluate the health gain obtainable from surgery for PDAC in relationship with age and tumor stage. METHODS: A Monte Carlo simulation model was built taking into consideration pertinent literature from population-based studies regarding surgical and non-surgical outcomes for stages I-II PDAC...

BACKGROUND: The literature reports a significant association between various mental disorders and asthma, in particular depression and/or anxiety, with some more robust data regarding anxiety disorders. However, the nature of this association remains largely unclear. OBJECTIVES: (1) To test the hypothesis of a specific association of anxiety and depressive disorder (according to the DSM-IV) with asthma and (2) to test the bidirectional hypothesis of causality between asthma and psychiatric disorders...

High-resolution inelastic neutron scattering and extensive first-principles calculations have been used to explore the low-temperature phase of the hybrid solar-cell material me-thylammonium lead iodide up to the well-known phase transition to the tetragonal phase at ca. 160 K. Contrary to original expectation, we find that the Pnma structure for this phase can only provide a qualitative description of the geometry and underlying motions of the organic cation. A substantial lowering of the local symmetry inside the perovskite cage leads to an improved atomis-tic model that can account for all available spectroscopic and thermodynamic data, both at low temperatures and in the vicinity of the aforementioned phase transition...

At rest the proportion between systolic and diastolic periods of the cardiac cycle is about 1/3 and 2/3 respectively. Therefore, mean blood pressure (MBP) is usually calculated with a standard formula (SF) as follows: MBP = diastolic blood pressure (DBP) + 1/3 [systolic blood pressure (SBP) - DBP]. However, during exercise this proportion is lost because of tachycardia, which shortens diastole more than systole. We analysed the difference in MBP calculation between the SF and a corrected formula (CF) which takes into account changes in the diastolic and systolic periods caused by exercise-induced tachycardia...

A series of novel unsymmetrical 2,5-disubstituted 1,3,4-oxadiazoles was synthetized and evaluated for their cytotoxic activity against different cancer cell lines of various origins as in vitro tumor models. Four of 12 new compounds (2b, 2h, 2j and 2l) showed growth inhibitory activity using the XTT dye assay. The most active agent, 2-(2-methyl-1,4-dihydroindeno[1,2-b]pyrrol-3-yl)-5-phenyl-1,3,4-oxadiazole, 2j, was chosen for further studies. It showed high potency against a panel of cultured human cancer cells with IC50 ranging from 0...

Electroconvulsive therapy (ECT), developed in the 30's by Bini and Cerletti, remains a key element of the therapeutic armamentarium in psychiatry, particularly for severe and life-threatening psychiatric symptoms. However, despite its well-established clinical efficacy, the prescription of ECT has declined constantly over the years due to concerns over its safety (cognitive side effects) and an increasingly negative public perception. As for other treatments in the field of psychiatry, ECT is well suited to a personalized approach that would increment its efficacy, as well as reducing the impact of side effects...

Infections continue to be one of the leading causes of morbidity and mortality in liver transplant recipients. We retrospectively reviewed the symptomatic infectious episodes that occurred during the first year post-transplant to determine time of onset, causative pathogens and cell-mediated immunity response patterns. Ninety-eight of the 202 (48.5%) recipients enrolled developed at least one infectious episode. The total number of infectious episodes was 135: 77 (57.1%) bacterial, 45 (33.3%) viral and 13 (9...

BACKGROUND: Many patients with primary liver cancers are not candidates for surgery, and systemic therapies are seldom effective. Selective internal radiation therapy (SIRT) has been shown to obtain partial and even complete response in unresectable primary tumors. As a "side effect", SIRT can induce contra-lateral liver hypertrophy. Tumor response to SIRT can be sufficient to allow disengagement from normal vital structures whose involvement is the cause of the initial unresectability...
