Objective: The aim of the study was to investigate the efficacy of extracorporeal shock wave therapy on myofascial pain syndrome in the neck and shoulder compared with that of other treatments.

Data Sources: PubMed, Embase, and Web of Science were systematically searched until May 30, 2019, to select randomized controlled trials.

Review Methods: The randomized controlled trials comparing extracorporeal shock wave therapy with sham extracorporeal shock wave therapy or other treatments for patients with myofascial pain syndrome in the neck and shoulder patients were included.

Objective: The aim of the study was to compare the effects of hydrotherapy and land-based conventional therapy on postural balance and knee strength in stroke patients.

Designs: A comprehensive search was done via databases (PubMed, EMBASE, and Web of Science) until April 12, 2019, to select randomized controlled trials. The methodological quality was assessed by the PEDro scale.

Introduction: Patients with overlapping Miller Fisher syndrome (MFS), Guillain-Barré syndrome (GBS), and the Bickerstaff brainstem encephalitis (BBE) have rarely been reported, and the diverse clinical features and sequelae are challenging for physicians. Through this case report, we present the clinical course, treatment, recovery, and sequelae of an overlapping MFS, GBS, and BBE syndrome and provide a review of the literature.

Case Report: A 76-year-old woman was initially presented with diplopia, ophthalmoplegia, and ataxia, but she later developed weakness of limbs, respiratory failure, deterioration of consciousness, and cognitive impairment.

Objective: To determine whether patients with lumbosacral (LS) radiculopathy and peripheral polyneuropathy (PPNP) exhibit sudomotor abnormalities and whether SUDOSCAN (Impeto Medical, Paris, France) can complement nerve conduction study (NCS) and electromyography (EMG).

Methods: Outpatients with lower extremity dysesthesia underwent electrophysiologic studies and SUDOSCAN. They were classified as normal (group A), LS radiculopathy (group B), or PPNP (group C).

Objective: To investigate the clinical characteristics of patients involved in road traffic accidents according to the New Injury Severity Score (NISS).

Methods: In this study, medical records of 1,048 patients admitted at three hospitals located in different regions between January and December 2014 were retrospectively reviewed. Only patients who received inpatient treatments covered by automobile insurance during the period were included.

Two ink genes, inkO and inkD, responsible for the earliest steps of K252a biosynthetic pathway, from Nonomurea longicantena JCM 11136 were heterologously coexpressed in Streptomycesalbus J1074. The resultant strain accumulated compound that was purified by HPLC and studied by NMR. Coexpression of inkOD yielded chromopyrrolic acid, the key intermediate in an indolocarbazole biosynthesis.

Magnaporthe grisea is a fungal pathogen of rice that forms appressoria that penetrate the outer cuticle of the rice plant. Data from recent studies indicate that M. grisea isocitrate lyase (ICL), a key enzyme in the glyoxylate cycle, is highly expressed during appressorium-mediated plant infection.

Indolocarbazole metabolite K-252a is a natural product that was previously reported as a potent protein kinase C inhibitor with in vitro and in vivo potency. From a biosynthetic viewpoint, this compound possesses structurally interesting features such as an unusual furanosyl sugar moiety, which are absent in the well-studied staurosporine and rebeccamycin. A cosmid library from genomic DNA of Nonomuraea longicatena JCM 11136 was constructed and screened for the presence of genes to be involved in the biosynthesis of indolocarbazole K-252a.
