In a single transient middle cerebral artery occlusion model of stroke and using immunohistochemical techniques, the effects of a new therapeutic approach named Gemst (a member of the Poly-L-Lysine innovative therapies) have been studied in the rat brain. The expression of inflammatory (CD45, CD11b), oxidative (NO-tryptophan, NO2-tyrosine) and indoleamine 2, 3-dioxygenase pathway (kynurenic acid, 3-hydroxy anthranilic acid) markers has been evaluated in early and late phases of stroke. For this purpose, we have developed eight highly specific monoclonal antibodies directed against some of these markers...

Cereal-based beverages contain a complex mixture of various polymeric macromolecules including polysaccharides, peptides, and polyphenols. The molar mass of polymers and their degradation products affect different technological and especially sensory parameters of beverages. Asymmetrical flow field-flow fractionation (AF4) coupled with multi-angle light scattering (MALS) and refractive index detection (dRI) or UV detection (UV) is a technique for structure and molar mass distribution analysis of macromolecules commonly used for pure compound solutions...

This paper explores the content and extent of the burden of caregiving for Chinese families in transition. It sets out to understand how Chinese families manage to balance family caregiving responsibilities with employment, the impact of the existing social institutions on family caregiving practices, and the risks that caregivers have to face. Data were collected from a sample of 214 workers from 14 manufacturing companies in an industrialized city in central China in 2013. Analysis revealed that common types of eldercare were assisting with activities of daily living and medical related care; middle aged employed respondents were most likely to be the caregivers to older family members; financial and time demands of care were challenging for caregivers, but women with more education and a secure job responded to the pressure of care giving better than those with less education and insecure jobs...

Since intravenous thrombolysis (IVT) is often associated with poor outcomes in hypertensive patients with severe acute cerebral infarction (ACI) due to occlusions of the internal carotid, basilar, or proximal middle cerebral artery, we evaluated whether multimodal intra-arterial treatment (IAT) might improve functional outcomes in this patient population. We retrospectively reviewed the charts of eligible patients who underwent multimodal IAT including intra-arterial thrombolysis, mechanical thrombectomy, balloon and/or stent angioplasty (IAT group) or IVT alone (IVT group)...

BACKGROUND AND OBJECTIVE: Previous studies firmly proved that an irregular aneurysmal shape was strongly associated with intracranial aneurysm (IA) rupture, but it is unclear how irregularly shaped intracranial aneurysms (IAs) form. We aimed to identify the factors related to irregular shape of IAs. METHOD: We retrospectively analyzed of consecutive patients evaluated or treated for IA at our institution from June 2015 to July 2016. According to the imaging morphology of aneurysm, the enrolled patients are divided into irregular and regular group...

BACKGROUND: Several recreational activities such as roller skating, skateboarding, and scooter riding create the risk for hand injuries, which are the fourth most commonly injured body part in relation to their use. Seymour first identified a specific pattern of digit injury as an open fracture affecting the distal phalangeal physis associated with nail avulsion from the eponychial fold. In this article, we report a series of Seymour fractures associated with misuse of the newly emerging recreational/transportation vehicle, the hoverboard...

Von Willebrand factor (VWF) is a key protein in hemostasis as it mediates adhesion of blood platelets to a site of vascular injury. A proper distribution of VWF lengths is important for normal functioning of hemostatic processes, because a diminished number of long VWF chains may significantly limit blood clotting and lead to bleeding, while an abundant number of long VWFs may result in undesired thrombotic events. VWF size distribution is controlled by ADAMTS13 protease, which can cleave VWF chains beyond a critical shear rate when the chains are stretched enough such that cleavage sites become accessible...

Invasive cervical resorption (ICR) is a type of external resorption that can involve the coronal, middle, and apical parts of the root in its advanced stages. The diagnosis and treatment of ICR depend on the extent of the resorption into the dentin. The treatment of advanced ICR is challenging, and these teeth have poor prognoses. This article describes 4 cases of class 4 ICR diagnosed by using cone-beam computed tomography and treated with a minimally invasive internal approach with sodium hypochlorite irrigation and calcium hydroxide dressing...

REVIEW
Donna M Denno, Shadae L Paul
Ninety-nine percent of the 5.9 million annual child deaths occur in low and middle-income countries. Undernutrition underlies 45% of deaths. Determinants include access to care, maternal education, and absolute and relative poverty. Socio-political-economic factors and policies tremendously influence health and their determinants. Most deaths can be prevented with interventions that are currently available and recommended for widespread implementation. Millennium Development Goal 4 was not achieved. Sustainable Development Goal 3...

Middle East respiratory syndrome-coronavirus (MERS-CoV) resembles a severe form of community-acquired pneumonia initially reported in Saudi Arabia in 2012. The MERS-CoV epidemic poses a big challenge because of its high mortality. In January 2015, a patient who was potentially incubating MERS-CoV arrived from the emergency department of another hospital and was admitted with acute coronary syndrome. This resulted in an outbreak in the cardiac surgery ward that caused the deaths of 5 of 6 patients who had undergone cardiac operations...

Africa's economy is growing faster than any other continent and it has been estimated that the middle class in Africa now exceeds 350 million people. This has meant a parallel increase in the importation of consumer goods and in the implementation of communication and information technologies (ICT), but also in the generation of large quantities of e-waste. However, inadequate infrastructure development remains a major constraint to the continent's economic growth and these highly toxic residues are not always adequately managed...

Insufficient is the evidence for safe use of elderly donors in adult-to-adult living donor liver transplantation (LDLT). The aim of this study was to evaluate the outcomes of right lobe LDLT by donor age (≥55 vs. <55 years). All living donors who underwent right hepatectomy at the authors' institution between March 2008 and December 2015 were divided into 2 groups: group A with an age ≥ 55 and group B with an age < 55. The selection criteria for elderly donor were preservation of middle hepatic vein, remnant liver volume ≥30%, and no or mild fatty liver...
