Recent studies indicated that insufficient radiofrequency ablation (RFA) could endow hepatocellular carcinoma (HCC) with higher aggressive potential. Stress-induced phosphoprotein 1 (STIP1), which was found highly expressed in HCC, is a chaperone molecule mediating cell homeostasis under thermal stress. We aimed to explore the role of STIP1 on the metastasis of residual HCC after RFA. Mice model with orthotopic HCC implants or caudal vein injection were employed to assess potential of lung metastasis and/or intrahepatic metastasis (IHM) of HCC cells...

Background: Cavitation is a serious consequence of tuberculosis. We tested the hypothesis that repetitive exposure to the same total bacterial burden of Mtb drives greater lung destruction than a single exposure. We also tested whether inhibition of endogenous MMP1 may inhibit cavitation during TB. Methods: Over a three weeks interval we infected rabbits with either 5 aerosols of 500 CFU of Mtb or a single aerosol of 2500 CFU plus four sham aerosols. We administered the MMP1 inhibitor cipemastat (100 mg/kg daily) from week 5-10 to a subset of the animals...

Preeclampsia is the most common cause of proteinuria with hypertension during pregnancy. Primary kidney disease and kidney disease secondary to systemic disorders may rarely occur during pregnancy, resulting in proteinuria. A 34-year-old woman was admitted to our hospital with abdominal distention and lower extremity edema. The pregnancy was terminated at the 24th week of gestation due to preterm labor. Even after the delivery, proteinuria and renal deterioration continued to progress. The M-peak was not found on serum and urine protein electrophoresis...

New phase diagrams for water confined in graphene nanocapillaries and single-walled carbon nanotubes (CNTs) are proposed, identifying ice structures, their melting points and revealing the presence of a solid-liquid critical point. For quasi-2D water in nanocapillaries, we show through molecular-dynamics simulations that AA stacking in multilayer quasi-2D ice arises from interlayer hydrogen-bonding and is stable up to three layers, thereby explaining recent experimental observations. Detailed structural and energetic analyses show that quasi-2D water can freeze discontinuously through a first-order phase transition or continuously with a critical point...

BACKGROUND: To describe and compare incidence, characteristics and outcomes of postoperative pneumonia among patients with or without COPD. METHODS: We included hospitalized patients aged ≥40 years whose medical diagnosis included pneumonia and ventilator-associated pneumonia in the secondary's diagnosis field and who were discharged from Spanish hospitals from 2001 to 2015. Irrespectively of the position at the procedures coding list, we retrieved data about the type of surgical procedures using the enhanced ICD-9-CM codes...

Recent theoretical and experimental studies reported ultra-high water permeability and salt rejection in nanoporous single-layer graphene. However, creating and controlling the size and distribution of nanometer-scale pores pose significant challenges to application of these membranes for water desalination. Graphyne and hydrogenated graphyne have tremendous potential as ultra-permeable membranes for desalination and wastewater reclamation due to their uniform pore-distribution, atomic thickness and mechano-chemical stability...

Vibrational spectra are commonly used to study molecular interactions in solutions. However, the data analysis is often demanding and requires significant experience in order to obtain meaningful results. This study demonstrates that principal component analysis (PCA) can serve as an unsupervised tool for initial screening of non-ideal mixture systems. Taking the aqueous solutions of dimethyl sulfoxide as an example, the PCA easily and fast reveals the two prominent stoichiometries at 1:2 and 1:1 molar DMSO:water ratio and significantly outperforms elaborate spectral profile analysis or common algorithms as indirect hard modeling (IHM) or multivariate curve resolution (MCR)...

Socially anxious individuals report higher social fears and feelings of distress in interpersonal interactions. Structural neuroimaging studies indicate brain morphological abnormalities in patients with social anxiety disorder, but findings are heterogeneous and partially discrepant. Studies on structural correlates of socially anxious tendencies in participants without clinical diagnoses are scarce. By using structural magnetic resonance imaging, the present study examined the relationship between social interaction anxiety and gray matter volume in 38 healthy women...

OBJECTIVE: Stress is linked to negative cardiovascular consequences and increases in depressive behaviors. Environmental enrichment (EE) involves exposure to novel items that provide physical and cognitive stimulation. EE has behavioral, cognitive, and neurobiological effects that may improve stress responses in humans and animal models. This study investigated the potential protective effects of EE on behavior and cardiovascular function in female prairie voles following a social stressor...

BACKGROUND/AIM: A review of the literature related to in-hand manipulation (IHM) revealed that there is no assessment which specifically measures this construct in the adult population. This study reports the face and content validity of an IHM assessment for adults with impaired hand function based on expert opinion. METHODS: The definition of IHM skills, assessment tasks and scoring methods identified from literature was discussed in a focus group (n = 4) to establish face validity...

We aimed to elucidate the role of autonomic dysfunction in the context of complex metabolic and cardiovascular changes in subjects with prehypertension. We identified 556 asymptomatic subjects without hypertension who underwent comprehensive cardiovascular exams. We obtained heart rate recovery (HRR) after peak exercise to quantitatively measure autonomic dysfunction. Of the 556 participants, 279 individuals had prehypertension and the remaining 277 had optimal BP. HRR was significantly lower in the prehypertension group (36...

OBJECTIVES: We investigated specific lactate thresholds for adverse outcomes in patients presenting to emergency departments (EDs) with suspected sepsis identified based on the performance of a sepsis screening algorithm. DESIGN AND SETTING: A standardised sepsis bundle was implemented across public hospitals in New South Wales, Australia, as a quality improvement initiative. A register of all adult ED presentations (≥18 years) meeting predefined criteria for sepsis was created, using a combination of data linkage and direct reporting from 97 participating sites...

Background: Hemangiomas of the soft tissue are common in the head and neck area, especially in the tongue and in children under ten years of age. Intraosseous hemangiomas of the mandible and maxilla (IHM), on the other hand, are exceedingly rare and are not well characterized. This study presents six IHM cases focusing on the clinical, radiographic, and histologic characteristics. Material and Methods: Six cases of IHM were retrieved from the archives of the Biopsy Services at the University of Washington...

International Health and Medical Services (IHMS) are contracted to provide health services, including catch-up vaccination, for individuals in immigration detention. Our audit of catch-up vaccination in asylum seeker children who spent time in held detention demonstrates inadequate and suboptimal vaccine delivery in this setting, and no evidence that IHMS recorded vaccines on the Australian Childhood Immunisation Register at the time. We also found substantial shortfalls in vaccination for these children after they were released from detention...

PURPOSE: The influence of the dipeptidyl peptidase-IV inhibitor, gemigliptin alone or in combination with metformin on survival, proliferation, and migration of thyroid carcinoma cells was investigated. METHODS: SW1736 and TPC-1 human thyroid carcinoma cells were used. RESULTS: Gemigliptin and metformin caused cell death in a dose-dependent manner. In cells treated with both gemigliptin and metformin, compared with metformin alone, all of the combination index values were lower than 1...
