Muscle activity monitoring or Electromyography (EMG) is a useful tool. However, EMG is typically invasive, expensive and difficult to use for untrained users. A possible solution is textile-based surface EMG (sEMG) integrated into clothing as a wearable device. This is, however, challenging due to (i) uncertainties in the electrical properties of conductive threads used for electrodes, (ii) imprecise fabrication technologies (e.g., embroidery, sewing), and (iii) lack of standardization in design variable selection...

Nondiphtheria Corynebacterium species are often dismissed as culture contaminants, but they have recently become increasingly recognized as pathologic organisms. We present the case of a 48-year-old male patient on chronic prednisone therapy for rheumatoid arthritis with a history of mitral valve replacement with prosthetic valve. He presented with fever, dizziness, dyspnea on exertion, intermittent chest pain, and palpitations. Transesophageal echocardiography revealed two medium-sized densities along the inner aspect of the sewing ring and one larger density along the atrial surface of the sewing ring consistent with vegetation...

While the term "image-guided surgery" has gained popularity fairly recently, the use of imaging for medical interventions dates as far back as the beginning of the 20th century. Dr. George H. Gray of Lynn, Massachusetts, reported in his 1908 article "X-rays in Surgical Work," published in volume 2 of the Journal of Therapeutics and Dietetics, that "the one great stride in the handling of difficult cases was the accurate diagnosis made possible by the use of the X-rays." His story points to the day when a seamstress presented to his office with a broken sewing needle embedded in her hand...

Surgical aortic valve replacement is the most common procedure of choice for the treatment of severe aortic stenosis. Bioprosthetic valves are traditionally sewed-in the aortic root by means of pledget-armed sutures during open-heart surgery. Recently, novel bioprostheses which include a stent-based anchoring system have been introduced to allow rapid implantation, therefore reducing the duration and invasiveness of the intervention. Different effects on the hemodynamics were clinically reported associated with the two technologies...

Work-related musculoskeletal disorders (WMSDs) are a major hazard for sewing machine operators. Ergonomics education is recommended for reducing musculoskeletal disorders at workstations. This study aimed to evaluate the effect of an ergonomics education in reducing the exposure to risk factors for WMSDs among sewing machine operators. In this study of 278 workers, their exposure to the risk of WMSDs was assessed using the quick exposure check (QEC) scale prior to them attending an ergonomics education programme and then again 3 months after the programme...

The Coral Triangle is widely considered the most important centre of marine biodiversity in Asia while areas on its periphery such as the South China Sea, have received much less interest. Here, we demonstrate that a small population of the knobbly sea star Protoreaster nodosus in Singapore has similarly high levels of genetic diversity as comparable Indonesian populations from the Coral Triangle. The high genetic diversity of this population is remarkable because it is maintained despite decades of continued anthropogenic disturbance...

In this study, commercial surfactants have been investigated at economically viable dosage to enhance the enzymatic saccharification of pretreated wheat straw at high solid loadings. Twenty one surfactants were evaluated with pilot scale pretreated wheat straw and mechanism of surfactant action has been elucidated. One surfactant has improved the saccharification of dilute acid wheat straw (DAWS) by 26.4% after 24h and 23.1% after 48h while, steam exploded wheat straw (SEWS) saccharification was increased by 51...

The diagnosis of prosthetic valve endocarditis may be challenging in patients with an atypical clinical presentation. Virtually all infections associated with mechanical prosthetic valves are localized to the prosthesis-tissue junction at the sewing ring and are accompanied by tissue destruction around the prosthesis. Because the orifice of the mechanical prosthetic valve is made of metal and pyrolytic carbon, which do not enable the adherence of microorganisms, any vegetation originating from the interior of the valve orifice is usually rare...

Management of anesthesia for a child with an upper airway foreign body is fraught with particular challenges. We present the case of a 3-year-old girl who presented to the emergency department with a 12-cm sewing needle protruding from her mouth and unknown vascular involvement. We were faced with establishing a secure airway despite exclusion of mask ventilation or use of a laryngeal mask airway. Moreover, peripheral intravenous access was lost before adequate sedation. Ultimately, we were able to safely induce anesthesia and achieve endotracheal intubation...

Research on the identity of genes and their relationship with traits of economic importance in chickens could assist in the selection of poultry. In this study, an F2 resource population of Gushi chickens crossed with Anka broilers was used to detect single-nucleotide polymorphisms (SNPs) in the flanking region of the ASB15 gene by DNA sequencing and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). One SNP of -1271 C>T in 5' flanking region of the chicken ASB15 gene and two SNPs of the 10618 A>G and 10716 G>A in 3' flanking region were identified...

Lightweight artificial muscle fibers that can match the large tensile stroke of natural muscles have been elusive. In particular, low stroke, limited cycle life, and inefficient energy conversion have combined with high cost and hysteretic performance to restrict practical use. In recent years, a new class of artificial muscles, based on highly twisted fibers, has emerged that can deliver more than 2,000 J/kg of specific work during muscle contraction, compared with just 40 J/kg for natural muscle. Thermally actuated muscles made from ordinary polymer fibers can deliver long-life, hysteresis-free tensile strokes of more than 30% and torsional actuation capable of spinning a paddle at speeds of more than 100,000 rpm...

INTRODUCTION: Intracranial needles are rare entities. Intracranial foreign bodies due to non-missile intracranial penetrations are one of the most rarely encountered situations in neurosurgery. Sewing needles are among the more unusual foreign bodies that may be found in the brain. Although uncommon, foreign body cases are important and interesting. Foreign bodies enter the body through trauma or iatrogenic injuries. Needles are mostly inserted through fontanelles, cranial sutures, and more rarely through the orbits in infancy for the purpose of killing unwanted babies...
