BACKGROUND: Placental transfusion (by means of delayed cord clamping (DCC), cord milking, or cord stripping) confers benefits for preterm infants. It is not known if providing respiratory support to preterm infants before cord clamping improves outcomes. OBJECTIVES: To assess the efficacy and safety of respiratory support provided during DCC compared with no respiratory support during placental transfusion (in the form of DCC, milking, or stripping) in preterm infants immediately after delivery...

Spinal cord injury (SCI) leads to bereft voluntary control of bladder, but the possible role of spontaneous excited system in bladder of SCI patients is poorly understood. Hyper-polarization-activated cyclic nucleotide-gated (HCN) channels are deemed to regulate the spontaneous contraction of bladder, our study explored the functional role of HCN channels in SCI induced neurogenic bladder. Sixty female Sprague-Dawley rats were randomized into control, sham and SCI groups. Rat models subjected to SCI at S2 levels were successfully established and were assessed using hematoxylin and eosin staining and cystometry...

Contrary to traditional planar flexible piezoelectric nanogenerators (PNGs), highly adaptable hemispherical shape-flexible piezoelectric composite strip (HS-FPCS) based PNGs are required to harness/measure non-linear surface motions. Therefore, a feasible, cost-effective and less-time consuming groove technique was developed to fabricate adaptable HS-FPCSs with multiple lengths. A single HS-CSPNG generates 130 V/0.8 μA and can also work as a self-powered muscle monitoring system (SP-MMS) to measure maximum human body part movements, i...

BACKGROUND: In recent years, spinal surgery has incorporated the many advantages of navigation techniques to facilitate the placement of pedicle screws during osteosynthesis, mainly for degenerative diseases. However, spinal intradural tumors are not clearly visible by intraoperative fluoroscopy or computed tomography scans, thereby making navigation necessary. OBJECTIVE: To evaluate the use of spinal navigation for the removal of intradural and spinal cord tumors using spinal magnetic resonance imaging (MRI) merged with intraoperative 3-dimensional (3-D) fluoro images...

RATIONALE: The spinal cord compression caused by intraspinal epidural fibrous cord. PATIENT CONCERNS: All patients in this study had spinal cord compression syndrome caused by an intraspinal epidural fibrous cord, manifested as abnormally increased epidural adipose tissue by imaging. DIAGNOSE: These abnormal fibrous connective tissue strips were not identical to the known pathological tissue such as "meningovertebral ligament." Instead, it might be a novel pathogenic cause for the spinal cord compression...

OBJECTIVE: Postnatal resident endothelium of blood vessels has been proposed to represent terminally differentiated tissue that does not replicate. We previously isolated endothelial colony-forming cells (ECFCs) from human umbilical cord blood (CB) and term placenta by using colony-forming assays and immunocytochemistry. We showed that ECFCs are highly proliferative and form functioning vessels in vivo, the defining characteristics of a true endothelial progenitor cell. This exploratory investigation was conducted to determine whether the endothelium of healthy adult blood vessels contained resident ECFCs...

Proteolysis is a process where proteins are broken down into smaller polypeptides or amino acids, comprising one of the important posttranslational modifications of proteins. Since this process is exquisitely achieved by specialized enzymes called proteases under physiological conditions, abnormal protease activity and dysregulation of their substrate proteins are closely associated with a progression of several neurodegenerative diseases including Alzheimer disease, Parkinson disease, stroke, and spinal cord injury...

OBJECTIVES: Regenerative medicine is an emerging field aimed at the repair and regeneration of various tissues. To this end, cytokines (CKs), growth factors (GFs), and stem/progenitor cells have been applied in this field. However, obtaining and preparing these candidates requires invasive, costly, and time-consuming procedures. We hypothesised that skeletal muscle could be a favorable candidate tissue for the concept of a point-of-care approach. The purpose of this study was to characterize and confirm the biological potential of skeletal muscle supernatant for use in regenerative medicine...

Neurogenic detrusor overactivity (NDO) is among the most challenging complications of spinal cord injury (SCI). A recent report by us demonstrated an improvement in NDO in SCI rats following chronic systemic treatment with the purine nucleoside inosine. The objective of this study was to investigate the mechanism of action of inosine underlying improvement of NDO. Male Sprague-Dawley rats underwent complete spinal cord transection at T8. Inosine (1 mM) delivered intravesically to SCI rats during conscious cystometry significantly decreased the frequency of spontaneous non-voiding contractions...

INTRODUCTION: Omphalitis is the infection of the umbilical cord stump, which can lead to septicaemia and significant neonatal morbidity and mortality. Very little data is available on the aetiology of neonatal omphalitis in India. AIM: To identify the causative agents of omphalitis in neonates and determine the antimicrobial susceptibility patterns of the isolates. MATERIALS AND METHODS: A prospective study was conducted at ESI-PGIMSR and ESIC Medical College, Joka, a tertiary care teaching hospital in Eastern India for a period of four months (from 1st January 2016 to 30th April 2016)...

BACKGROUND: Vascular lesions of the spinal cord are increasingly recognized. The most common types of these lesions are dural arteriovenous fistulas (AVFs) whereas, extradural AVFs are a very rare type of spinal AVF and can be associated with either extradural or intradural venous reflux. This results in neurological deficits through congestive or compressive myeloradiculopathy. These lesions must be treated to allow stabilization or improvement of neurologic status, either by endovascular therapy or microsurgical interruption...

Motor units are the fundamental elements responsible for muscle movement. They are formed by lower motor neurons and their muscle targets, synapsed via neuromuscular junctions (NMJs). The loss of NMJs in neurodegenerative disorders (such as amyotrophic lateral sclerosis or spinal muscle atrophy) or as a result of traumatic injuries affects millions of lives each year. Developing in vitro assays that closely recapitulate the physiology of neuromuscular tissues is crucial to understand the formation and maturation of NMJs, as well as to help unravel the mechanisms leading to their degeneration and repair...

Primary laryngeal aspergillosis is extremely rare, especially in an immunocompetent host. It is commonly found as a part of systemic infection in immunocompromised patients. A case of vocal cord aspergillosis with no systemic extension in an immunocompetent patient on long-term steroid metered dose inhaler (MDI) is presented here, because of its rarity. The present case is a 28-year-old asthmatic female who was on inhalational steroid for 8 years, presented with sudden onset of severe dysphonia for 5 days. Fiberoptic laryngoscopy demonstrated whitish plaque involving right vocal cord, clinically suggestive of fungal laryngitis...

Laryngeal aspergillosis is most commonly seen as a result of secondary invasion from the lungs and tracheobronchial tree in immunocompromised hosts. Primary aspergillosis of the larynx is, however, rare with few cases documented over the past fifty years. We report a case of a 73-year-old woman who presented with persistent hoarseness. She is a nonsmoker with a history of asthma and chronic bronchiectasis treated with bronchodilators, inhaled and oral corticosteroids, and nebulized tobramycin. Direct laryngoscopy with vocal cord stripping confirmed the diagnosis of invasive aspergillosis with no manifestations elsewhere...

OBJECTIVE: To explore the imaging features of spinal cord and spinal meningeal tuberculosis by magnetic resonance (MR). METHODS: We analyzed retrospectively the features of MRI in 23 patients with spinal cord and spinal meningeal tuberculosis compared to 25 patients with spinal cord meningeal metastatic carcinoma. All patients were admitted in our hospital from Jun. 2011 to Oct. 2014. There were 12 males and 11 females with a median age of 26 (range 16-50) years in the spinal cord meningeal tuberculosis group, and 18 males and 7 females with a median age 56 (range 44-78) years in the spinal cord meningeal metastatic carcinoma group...
