Lemierre syndrome is an uncommon condition in which internal jugular vein thrombosis presents after recent oropharyngeal infection. Frequently, this is accompanied by septic emboli. This report outlines a variant of this disease process, with septic thrombophlebitis of the neck associated with a necrotizing skin infection of the lower lip and chin. A 25-year-old man with lower lip and chin swelling, initially managed with intravenous antibiotics, progressed to the development of a left facial vein thrombus, septic emboli to the lungs, and a necrotizing lower lip and chin infection that was managed with debridement, thrombectomy, and prolonged hemodynamic and pulmonary support...

This paper aims to study Twist protein expression in colorectal carcinoma and its effect on the proliferation and invasion of colorectal cancer cells, and to explore its specific mechanism of promoting cancer. Tissues of 20 patients and specimens of 20 normal people were examined by colonoscopy biopsy; the Twist mRNA expression level was detected by real-time quantitative PCR; the RNA interference in colorectal carcinoma cell line CT-26 cells was performed by lipid transfection method; the effects of Twist interference on proliferation and invasion of colorectal cancer cells were observed by CCK8 assay and tran swell assay; the mRNA and protein levels of mRNA in CT-26 cells were detected by RT-PCR and Western blot...

This study was aimed to explore the combined effects of Exendin-4 with dipeptidyl peptidase-IV (DPP-4) silencing on vascular endothelial growth factor (VEGF)-induced cell proliferation and angiogenesis in Human Coronary Artery Endothelial Cells (HCAECs), as well as the underlying molecular mechanisms which were involved in this process. HCAECs were treated by exendin-4, small interfering RNA (siRNA) targeting DPP-4 (DPP-4-siRNA) or exendin-4 plus DPP-4-siRNA, respectively. Cell migration, proliferation and angiogenesis in vitro were assessed by scratch-wound assay, MTT, tran swell assay, and matrigel tube formation, respectively...

OBJECTIVE: Lyme borreliosis (LB) is a tick-borne infectious disease caused by Borrelia burgdorferi spirochaetes, which are able to disseminate from the tick-bite site to distant organs. Mouse models are widely used to study LB and especially Lyme arthritis (LA), but only a few whole-animal in vivo imaging studies on the pathogenesis of B. burgdorferi infection in mice have been published so far. The existing imaging techniques have their drawbacks and, therefore, novel tools to complement the array of available LB imaging methodologies are needed...

BACKGROUND: Dry eye syndrome is a disorder of the tear film that is associated with symptoms of ocular discomfort. Punctal occlusion is a mechanical treatment that blocks the tear drainage system in order to aid in the preservation of natural tears on the ocular surface. OBJECTIVES: To assess the effects of punctal plugs versus no punctal plugs, different types of punctal plugs, and other interventions for managing dry eye. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 11), MEDLINE Ovid (1946 to 8 December 2016), Embase...

The notochord, a conserved axial structure required for embryonic axis elongation and spine development, consists of giant vacuolated cells surrounded by an epithelial sheath [1-3]. During morphogenesis, vacuolated cells maintain their structural integrity despite being under constant mechanical stress [4]. We hypothesized that the high density of caveolae present in vacuolated cells [5, 6] could buffer mechanical tension. Caveolae are 50- to 80-nm membrane invaginations lined by cage-like polygonal structures [7, 8] formed by caveolin 1 (Cav1) or Cav3 and one of the cavin proteins [6, 9-11]...

An 11-year-old boy living in Otsu City, Shiga Prefecture, Kansai Region, Western Honshu, Japan had zoonotic onchocercosis. The patient developed a painful swelling on the little finger of his left hand. The worm detected in the excised mass had external transverse ridges but did not have inner striae in the cuticle. On the basis of the parasite's histopathological characteristics, the causative agent was identified as a female Onchocerca dewittei japonica (Spirurida: Onchocercidae). The species of the filarial parasite was confirmed by sequencing the cox1 gene of the parasite...

Superior vena cava (SVC) syndrome, characterized by facial and arm swelling, is most frequently caused by intrathoracic malignancies. Decompression may be achieved with endovenous stent placement. Polytetrafluoroethylene-covered stents have shown to have higher long-term cumulative patency rates compared with uncovered stents for the treatment of malignant SVC syndrome. Unfortunately, polytetrafluoroethylene-covered stents are not readily available worldwide. Moreover, the existing armamentarium, including balloon-expandable iCAST stents (maximum diameter 10 mm) and heparin-coated Viabahn stent-graft endoprostheses (maximum diameter 13 mm), are too small to adequately treat malignant obstruction of the SVC...

The polyelectrolyte matrix tablets loaded with an oppositely charged drug exhibit complex drug-release mechanisms. In this study, the release mechanism of a cationic drug doxazosin mesylate (DM) from matrix tablets based on an anionic polyelectrolyte λ-carrageenan (λ-CARR) is investigated. The drug release rates from λ-CARR matrices are correlated with binding results based on potentiometric measurements using the DM ion-sensitive membrane electrode and with molecular characteristics of the DM-λ-CARR-complex particles through hydrodynamic size measurements...

Hepatic encephalopathy (HE) represents a serious complication of acute liver failure (ALF) in which cerebral edema leading to brainstem herniation as a result of increased intracranial hypertension is a major consequence. Long non-coding RNAs (lncRNAs) play a significant role in coordinating gene expression, with recent studies indicating an influence in the pathogenesis of several diseases. To investigate their involvement in the cerebral pathophysiology of ALF, we profiled the expression of lncRNAs in the frontal cortex of mice at coma stage following treatment with the hepatotoxin azoxymethane...

Although copper is an essential micronutrient involved in a variety of biological processes indispensable for sustaining life, it can be toxic when administered in excess. Licorice (Glycyrrhizaglabra) has been used in Chinese folk medicine for the treatment of various disorders. Licorice has the biological capabilities of detoxication, antioxidation, and antiinfection. Here, we test the hypothesis that licorice could ameliorate copper-induced neurotoxic and genotoxic effects in adult male albino rats. For this purpose, 48 adult male albino rats were randomized into five groups: group I (8 rats), untreated control; group II (16 rats), subdivided into; vehicle control IIa (8 rats) which received 1 mL saline twice weekly intraperitoneally for 8 weeks and vehicle control IIb (8 rats) received 0...

The structures of the compact and swollen southern bean mosaic virus (SBMV) particles have been compared by X-ray diffraction and proton magnetic resonance (PMR). Small-angle X-ray scattering showed that removal of divalent cations at alkaline pH causes the particle diameter to increase from 289Å in the native SBMV by 12% in solution and by 9% in microcrystals. The swelling is fully reversible upon re-addition of Ca(2+)and Mg(2+) ions, as shown by the X-ray patterns at 6 Å resolution and by the 270 MHz PMR spectra...

Karan Dua, James M Barsi
Heterotopic ossification (HO) is abnormal formation of mature lamellar bone in soft tissues. HO is most commonly diagnosed in the setting of localized trauma, which results in improper differentiation of progenitor cells, leading to aberrant tissue formation. In the pediatric population, nongenetic causes of HO have rarely been reported, especially HO involving the tendons of the ankle. We present a case of HO of the peroneus brevis tendon without systemic disease in a pediatric patient. The patient was a 7-year-old female with a normal birth and developmental history who first presented 6 weeks after a right ankle sprain with pain localized to the lateral calcaneus...

BACKGROUND: Musculoskeletal findings in Sjögren's syndrome are arthralgia, arthritis, myalgia, myositis, fibromyalgia, and chronic fatigue. Enthesis zones are important in the formation of pain in the musculoskeletal system. Musculoskeletal ultrasound (US) may show subclinical enthesitis in the synovial joints and in the axial skeleton before joint swelling in inflammatory diseases characterized by arthritis. OBJECTIVE: In this study, we aimed to determine the presence of enthesopathy using the Madrid sonographic enthesitis index (MASEI) in patients with primary Sjögren's syndrome (PSS)...
