Leucine-rich-α-2-glycoprotein 1 (LRG1) is considered as a potential biomarker as it is aberrantly expressed in various malignancies. However, there is limited information regarding its role in head and neck squamous cell carcinoma (HNSCC). In the present study, we aimed to explore the expression pattern of LRG1 in HNSCC and its clinicopathological significance. We first analyzed LRG1 gene expression in HNSCC by investigating data obtained from the Gene Expression Omnibus (GEO) database. The results showed that LRG1 was downregulated in HNSCC tissues and its expression level was negatively related to tumor T and N stages and degree of malignancy...

The tissue microenvironment functions as a crucial player in carcinogenesis, and transforming growth factor-β1 (TGF-β1) within the microenvironment stimulates the formation of neoplasms. Using an in vitro model of malignancy induced by TGF-β1, we assessed the effect of evodiamine and berberine on the interaction between DNA methyltransferases (DNMTs) and target microRNAs (miRNAs) in the model. Colon tissues from neonatal rats 7 days of age were cultured and malignancy was induced by TGF-β1 in vitro for 48 h, and then the tissues were respectively treated with evodiamine and berberine for 24 h...

The guinea pig is a useful model for investigating infectious and non‑infectious lung diseases due to the sensitivity of its respiratory system and susceptibility to infectious agents. Toll‑like receptors (TLRs) are important components of the innate immune response and are critical for lung immune function. In the present study, the differentiation of epithelial cells in the guinea pig lung was examined during gestation by studying anatomic morphology and the major epithelial cell types using cell type‑specific markers...

OBJECTIVE: To illustrate the marked differences between classical endocrinology that distributes hormones to all tissues of the body through the bloodstream and the science of intracrinology, whereby each cell of each peripheral tissue makes a small and appropriate amount of estrogens and androgens from the inactive precursor dehydroepiandrosterone (DHEA), DHEA being mainly of adrenal origin. Because only the inactivated sex steroids are released in the blood, influence in the other tissues is avoided...

Metal-on-metal (MOM) hip resurfacing has recently been a popular prosthesis choice for the treatment of symptomatic arthritis, but results in the release of cobalt and chromium ions into the circulation that can be associated with adverse clinical effects. The mechanism underlying these effects remains unclear. While chromosomal aneuploidy and translocations are associated with this exposure, the presence of subtle structural epigenetic modifications in patients with MOM joint-replacements remains unexplored...

Autophagy, a cell-survival process responsible for degradation of protein aggregates and damaged organelles, is increasingly recognized as another mechanism essential for human placentation. A substantial body of experiments suggests inflammation and oxidative stress as the underlying stimuli for altered placental autophagy, giving rise to placenta dysfunction and pregnancy pathologies. Here, the hypothesis is tested whether or not pro-inflammatory cytokines interleukin (IL)-6 and tumor necrosis factor (TNF)-α are able to influence the expression profile of autophagy genes in human first-trimester villous placenta...

Importance: Periodic discharges (PDs) that do not meet seizure criteria, also termed the ictal interictal continuum, are pervasive on electroencephalographic (EEG) recordings after acute brain injury. However, their association with brain homeostasis and the need for clinical intervention remain unknown. Objective: To determine whether distinct PD patterns can be identified that, similar to electrographic seizures, cause brain tissue hypoxia, a measure of ongoing brain injury...

Importance: Mechanical thrombectomy (MT) improves clinical outcomes in patients with acute ischemic stroke (AIS) caused by a large vessel occlusion. However, it is not known whether intravenous thrombolysis (IVT) is of added benefit in patients undergoing MT. Objective: To examine whether treatment with IVT before MT with a stent retriever is beneficial in patients undergoing MT. Design, Setting, and Participants: This post hoc analysis used data from 291 patients treated with MT included in 2 large, multicenter, prospective clinical trials that evaluated MT for AIS (Solitaire With the Intention for Thrombectomy performed from January 1, 2010, through December 31, 2011, and Solitaire Flow Restoration Thrombectomy for Acute Revascularization from January 1, 2010, through December 31, 2012)...

Optical imaging methods have been developed to measure lymphatic function in skin; however, the lymphatic system of many organs is not accessible to this technology. Since lymphatic transport of macromolecules from any organ proceeds to the blood circulation, we aimed to develop a method that can measure lymphatic function by monitoring the fluorescence in a superficial vein of an interstitially injected tracer. We selected a 40-kDa PEGylated near-infrared dye conjugate, as it showed lymphatic system-specific uptake and extended circulation in blood...

BACKGROUND AND AIMS: Epiretinal membrane (ERM) refers to a semi-translucent tissue layer found on the inner surface of the retina especially in older people. Surgical treatment remains controversial, optimal timing for such treatment is difficult to determine and data on the natural evolution of this disorder are limited. In this study we evaluated the natural course of idiopathic epimacular membrane in 49 patients (53 eyes). MATERIALS AND METHODS: Retrospective evaluation of a group of 49 patients (53 eyes) with idiopathic epimacular membrane confirmed by biomicroscopy, photography and optical coherence tomography (OCT)...

♦ Background: Peritoneal dialysis (PD) is characterized by a gain in fat mass. The fat tissue is a complex endocrine organ that releases various adipokines. In this study, we prospectively examined serial changes of fat composition and adipokines in patients undergoing PD. ♦ Methods: Body composition was assessed by computed tomography (CT). Nutrition status and adipokines (leptin, adiponectin, interleukin [IL]-6, and tumor necrosis factor [TNF]-α) were assessed on the 7th day and 6 months, 12 months, and 24 months after the start of PD...

Down-sloped or hooked acromion morphologies may cause bony encroachment on the soft tissues of the subacromial space, predisposing to shoulder impingement syndrome. Of the latter, a hooked or Type III acromion (T3A) has also been linked to rotator cuff (RC) pathology. However, as bony acromial impingement is typically thought to occur over the age of 40, its occurrence in younger shoulder athletes presenting with shoulder pain, impingement and RC pathology may be overlooked. This case serves to illustrate the occurrence of T3A in a younger shoulder athlete, and the importance of early imaging in achieving diagnostic accuracy...

Cardiotrophin (CT)-1 is a regulator of glucose and lipid homeostasis. In the present study, we analyzed whether CT-1 also acts to peripherally regulate metabolic rhythms and adipose tissue core clock genes in mice. Moreover, the circadian pattern of plasma CT-1 levels was evaluated in normal-weight and overweight subjects. The circadian rhythmicity of oxygen consumption rate (Vo2) was disrupted in aged-obese CT-1-deficient (CT-1(-/-)) mice (12 mo). Although circadian rhythms of Vo2 were conserved in young-lean CT-1(-/-) mice (2 mo), CT-1 deficiency caused a phase shift of the acrophase...

REVIEW
Alejandro Gugliucci
Fructose is associated with the biochemical alterations that promote the development of metabolic syndrome (MetS), nonalcoholic fatty liver disease, and type 2 diabetes. Its consumption has increased in parallel with MetS. It is metabolized by the liver, where it stimulates de novo lipogenesis. The triglycerides synthesized lead to hepatic insulin resistance and dyslipidemia. Fructose-derived advanced glycation end products (AGEs) may be involved via the Maillard reaction. Fructose has not been a main focus of glycation research because of the difficulty in measuring its adducts, and, more importantly, because although it is 10 times more reactive than glucose, its plasma concentration is only 1% of that of glucose...

BACKGROUND: Ancient microbiota information represents an important resource to evaluate bacterial evolution and to explore the biological spread of infectious diseases in history. The soft tissue of frozen mummified humans, such as the Tyrolean Iceman, has been shown to contain bacterial DNA that is suitable for population profiling of the prehistoric bacteria that colonized such ancient human hosts. RESULTS: Here, we performed a microbial cataloging of the distal gut microbiota of the Tyrolean Iceman, which highlights a predominant abundance of Clostridium and Pseudomonas species...

Meniscal injuries are the most frequently encountered soft tissue injuries in the equine stifle joint. Due to the inherent limited repair potential of meniscal tissue, meniscal injuries do not only affect the meniscus itself but also lead to impaired joint homeostasis and secondary osteoarthritis. The presented study compares 3D co-culture constructs of primary equine mesenchymal stem cells (MSC) and meniscus cells (MC) seeded on three different scaffolds - a cell-laden collagen type I hydrogel (Col I gel), a tissue-derived small intestinal matrix scaffold (SIS-muc) and a combination thereof - for their qualification to be applied for meniscus tissue engineering...
