Platelet-derived growth factor (PDGF) was discovered as a serum-derived component necessary for the growth of smooth muscle cells, fibroblasts, and glial cells. The PDGF family is a product of four gene products and consists of five dimeric isoforms: PDGF-AA, PDGF-BB, PDGF-CC, PDGF-DD, and the PDGF-AB heterodimer. This…

OBJECTIVES: Neuromyelitis optica spectrum disorder (NMOSD) causes disabling and persistent central neuropathic pain (NP). Because the pain syndrome in NMOSD is severe and often intractable to analgesic treatment, it interferes with quality of life in patients. No interventional trials have been published looking at res…

Central nervous system infections can be complications of neurosurgical procedures or can occur spontaneously, and occasionally lead to devastating neurological complications, increased rate of mortality, and lengthier stays in the hospital, subsequently increasing costs. The use of intrathecal antibiotics to bypass th…

BACKGROUND: To improve the efficiency of conducting multicenter clinical trials, the Food and Drug Administration, the Office of Human Research Protections, and the Department of Health and Human Services have expressed support for using a centralized institutional review board (IRB) process. However, research institut…

BACKGROUND: The problem of access to medical information, particularly in low-income countries, has been under discussion for many years. Although a number of developments have occurred in the last decade (e.g., the open access (OA) movement and the website Sci-Hub), everyone agrees that these difficulties still persis…

Dissemination of high-grade gliomas (WHO IV) has been investigated poorly so far. We conducted an extensive analysis of the characteristics, treatments and outcomes of the glioblastoma multiforme (GBM)/gliosarcoma (GS) patients with central nervous system (CNS) metastases reported in literature until April 2013. PubMed…

BACKGROUND: The bipyridyl herbicide paraquat was first introduced into agriculture in the 1960s by Imperial Chemical Industries. Due to issues with unintentional poisoning, the centrally acting emetic PP796 was added in 1976 to the company's 20% paraquat ion soluble liquid (SL20) formulations (Gramoxone) at a concentra…

INTRODUCTION: This review summarizes and analyzes the abnormal expression and mechanism of S100A16 in digestive system diseases, which is expected to provide new ideas and methods for adjuvant treatment and prognosis evaluation of digestive system diseases. AREAS COVERED: Based on original publications found in databa…

BACKGROUND: The PubMed database contains nearly 15 million references from more than 4,800 biomedical journals. In general, authors of scientific articles are addressed by their last name and forename initial. DISCUSSION: In general, names can be too common and not unique enough to be search criteria. Today, Ph.D. stud…

BACKGROUND: The dynamic intersection of a pluralistic health system, large informal sector, and poor regulatory environment have provided conditions favourable for 'corruption' in the LMICs of south and south-east Asia region. 'Corruption' works to undermine the UHC goals of achieving equity, quality, and responsivenes…

Hydrogel-based products are used in many areas of biomedicine and healthcare. Recently, the incorporation of cellulose nanocrystals (CNC), a renewable and functional nanomaterial, into hydrogels has enhanced their functionality, particularly by imparting mechanical strength and structural integrity. This scoping review…

INTRODUCTION: Fibromyalgia (FMS), or Fibro-Myalgia Syndrome, is a complex disorder characterized by pain, fatigue and impaired quality of life. FMS will affect a patient's functionality and often lead to significant disability. FMS remains underdiagnosed and undertreated and is an important comorbidity in patients with…

INTRODUCTION: The use of Information and Communication Technology (ICT) for assessing and treating cognitive and motor disorders is promoting home-based telerehabilitation. This approach involves ongoing monitoring within a motivating context to help patients generalize their skills. It can also reduce healthcare costs…

Paediatric patients who are critically unwell typically require a central venous access device (CVAD) to streamline medical procedures and minimise risks associated with repeated venipuncture. However, infectious and non-infectious complications are common, with considerable clinical and cost sequelae. This review aime…

AIMS: To compare the risk of phlebitis between midline catheters and peripherally inserted central catheters in infusion therapy with a meta-analysis. DESIGN: This was a systematic literature review and meta-analysis. DATA SOURCES: Web of Science, PubMed, Scopus, Embase, Cochrane Library, ProQuest, CNKI, WanFang, VIP…

PURPOSE: This meta-analysis was conducted to investigate whether usage of corticosteroids was associated with an increased risk of central serous chorioretinopathy by summarizing all available evidence. METHODS: PubMed, EMBASE, Cochrane Library, and Web of Science databases were searched for all relevant studies publi…

AIM: Mitochondria is one of the important organelles involved in cell energy metabolism and regulation and also play a key regulatory role in abnormal cell processes such as cell stress, cell damage, and cell canceration. Recent studies have shown that mitochondria can be transferred between cells in different ways and…

Drug delivery and distribution in the central nervous system (CNS) and the inner ear represent a challenge for the medical and scientific world, especially because of the blood-brain and the blood-perilymph barriers. Solutions are being studied to circumvent or to facilitate drug diffusion across these structures. Usin…

AIM: We performed a systematic review and meta-analysis to examine the accuracy and safety of using the electrocardiogram (ECG) positioning technique to localize the peripherally inserted central catheter (PICC) tip position to provide objective evidence for its clinical application. METHODS: We searched the literatur…

Traumatic injury to the central nervous system (CNS) and stroke initiate a cascade of processes that expand the area of tissue loss. The current review considers recent studies demonstrating that the induction of an anesthetic state or cooling the affected tissue (hypothermia) soon after injury can have a therapeutic e…
