The aim of this study was to evaluate the therapeutic effect of propolis on non-alcoholic fatty liver disease (NAFLD) in rats. The rats were randomly divided into 3 groups of 10 as the NAFLD, NAFLD+100 and NAFLD+200 groups. The rats were fed with a fatty diet (25g/kg/day) to provoke NAFLD. Then after the formation of fatty liver, a standard diet (SD) (25g/kg/day) was given to the NAFLD group and the other two groups were fed with SD and 100mg/kg (NAFLD+100 Group) or 200mg/kg propolis (NAFLD+200 Group) for two weeks...

Although extracts and consumed foods from Physalis species contain sucrose esters from their glandular trichomes, there is no experimental data available on their toxicological effects. As peruvioses A and B isolated from Physalis peruviana L. calyces have proved to be effective anti-inflammatory and immunomodulatory compounds, this work aimed to investigate their sub-acute toxicity study and genotoxicity. For this, CD-1(ICR) mice were treated intraperitoneally with peruvioses at doses of 2.5, 5, and 10mg/kg/day for 28 consecutive days, to simulate therapeutic and over-therapeutic dosage levels...

Drug liver-induced injury (DILI) due to minocyclin, alpha methyldopa or nitrofurantoin may be responsible for chronic liver damage that mimic the biological and/or histological features of chronic autoimmune hepatitis and, in rare cases, progresses to cirrhosis(1). Olmesartan medoxomil is an antihypertensive drug that acts by blocking the angiotensin II receptor and is metabolized into its pharmacologically active form, olmesartan, in the intestine and in the liver before being released into the systemic circulation...

Active lifestyles increase the risk of meniscal injury. A permanent meniscus implant of polycarbonate urethane (PCU) is a promising treatment to postpone/prevent total knee arthroplasty. Study of the changes in articular cartilage tribology in the presence of PCU is essential in developing the optimum meniscus implant. Therefore, a cartilage-meniscus reciprocating, sliding model was developed in vitro, mimicking the stance and swing phases of the gait cycle. The meniscus was further replaced with PCU and surface-modified PCUs (with C18 chains, mono-functional polydimethylsiloxane groups and mono-functional polytetrafluoroethylene groups) to study the changes...

This article describes the case history of a 59-year-old female patient who sought advice for temporomandibular joint (TMJ) pain and sounds but who was actually diagnosed with a primary lung cancer with metastasis to the TMJ. The patient had a history of TMJ pain and deflection in jaw movement that progressively worsened over a few months and did not improve with the usual standard of care treatment provided by an orofacial pain practitioner. Magnetic resonance and computed tomography (CT) prescribed at a tertiary clinic showed an osteolytic bone mass within the right TMJ condyle...

OBJECTIVES: Guidelines for diagnosing celiac disease (CD) recommend initial testing with a highly sensitive serologic test for anti-tissue transglutaminase immunoglobulin A antibodies (tTG IgA). When the probability of CD is high, IgA deficiency should be considered. The 2 approaches to address this include measuring "both tTG IgA and tTG IgG" or measuring "total IgA." We aim to assess the utility of an isolated positive tTG IgG result in diagnosing CD. METHODS: We conducted a retrospective review of patients undergoing serologic testing for CD from January 1997 to June 2014...

While radiotherapy continues to be a major cancer treatment option, its dose-limiting side effects, such as pulmonary fibrosis, severely impair the quality of life in these patients. In this study, we evaluated the radioprotective effects of metformin, a commonly used biguanide antidiabetic medication, in a murine model of pulmonary damage. Sprague Dawley(®) rats received whole lung 20 Gy irradiation with or without metformin treatment. Computed tomography (CT) was performed and Hounsfield units (HU) were determined during the observation period...

We have shown that nanoparticles (NPs) can be used as ligand-multimerization platforms to activate specific cellular receptors in vivo. Nanoparticles coated with autoimmune disease-relevant peptide-major histocompatibility complexes (pMHC) blunted autoimmune responses by triggering the differentiation and expansion of antigen-specific regulatory T cells in vivo. Here, we define the engineering principles impacting biological activity, detail a synthesis process yielding safe and stable compounds, and visualize how these nanomedicines interact with cognate T cells...

Diabetic nephropathy (DN) is a major cause of end-stage renal disease, and therapeutic options for preventing its progression are limited. To identify novel therapeutic strategies, we studied protective factors for DN using proteomics on glomeruli from individuals with extreme duration of diabetes (ł50 years) without DN and those with histologic signs of DN. Enzymes in the glycolytic, sorbitol, methylglyoxal and mitochondrial pathways were elevated in individuals without DN. In particular, pyruvate kinase M2 (PKM2) expression and activity were upregulated...

This study aimed to investigate the correlation between INSR gene polymorphisms on platinum-based chemotherapy sensitivity and prognosis in epithelial ovarian cancer (EOC). A total of 339 EOC patients receiving postoperative chemotherapy were recruited for the study. Tag single nucleotide polymorphism (tag SNP) of INSR gene was screened from HapMap combined with available literature. Frequency distribution of genotypes and alleles in INSR gene was sequenced by ABI3100-Avant. Compared with CC+GC genotype, INSR rs2252673 GG genotype and rs3745546 CC genotype showed less platinum-based chemotherapy sensitivity in EOC patients (OR=0...

Certain dietary supplements have been reported to increase the risk of some cancers. Over half of the US population regularly uses dietary supplements. Thyroid cancer incidence has increased over the past several decades. However, few studies have investigated the association between dietary supplements and thyroid cancer. Thus, it is essential to clarify any association between dietary supplements and risk of thyroid cancer. MATERIALS AND METHODS: A population-based case-control study in Connecticut was conducted during 2010-2011 among 462 histologically confi rmed incident thyroid cancer cases and 498 population-based controls...

Apoptosis has been regarded to mediate intervertebral disc degeneration (IDD); however, the basic question of how the apoptotic bodies are cleared in the avascular intervertebral disc without phagocytes, which are essential to apoptosis, remains to be elucidated. Our goals were to investigate the ultrastructure of nucleus pulposus (NP) cells undergoing chondroptosis, a variant of apoptotic cell death, in a rabbit annular needle-puncture model of IDD. Experimental IDD was induced by puncturing discs with a 16-G needle in New Zealand rabbits...

PathoSpotter is a computational system designed to assist pathologists in teaching about and researching kidney diseases. PathoSpotter-K is the version that was developed to detect nephrological lesions in digital images of kidneys. Here, we present the results obtained using the first version of PathoSpotter-K, which uses classical image processing and pattern recognition methods to detect proliferative glomerular lesions with an accuracy of 88.3 ± 3.6%. Such performance is only achieved by similar systems if they use images of cell in contexts that are much less complex than the glomerular structure...
