  • Kidney transplantation is the treatment of choice for patients with end-stage renal disease, as it extends survival and increases quality of life in these patients. However, chronic allograft injury continues to be a major problem, and leads to eventual graft loss. Early detection of allograft injury is essential for guiding appropriate intervention to delay or prevent irreversible damage. Several advanced MRI techniques can offer some important information regarding functional changes such as perfusion, diffusion, structural complexity, as well as oxygenation and fibrosis. This review highlights the potential of multiparametric MRI for noninvasive and comprehensive assessment of renal allograft injury.

  • The kinesiologic electromyograhy(KEMG) is one of the most common use in physical therapy for understanding normal function and dysfunction of the neuromuscular system. Physical therapists concerned to patterns of muscle response, position, type of muscle contraction, onset and cessation of activity, the level of muscle response in relation to effort, and type of muscle contraction. Also they are use KEMG to assess the exercises for facilitate or for inhibit specific muscle activity. However there is a few references that provide information of KEMG Thus, the purpose of this article is for the use and interpretation of KEMG data. This article will guide beginning researchers for collecting, managing and analyzing of KEMG data.

  • Rotator cuff tear is often cited as a reason for shoulder pain and dysfunction in patients > 40 years of age. Surgical repair of rotator cuff tear is one of the most commonly performed orthopedic surgical procedures. Until now, the success rate of surgical repair for rotator cuff tear has not been satisfactory. Many factors influence the process of rotator cuff repair such as the presence of tendinosis and fatty infiltration, but the main factor is the difficulty in achieving healing at the tendon to bone interface. There is a clinical need for bioengineering approaches to promote regeneration of the native enthesis and reduce the poor outcomes after surgical repair. Toward this end, the design and fabrication of multiphasic or hierarchically structured scaffolds have received great attention. This manuscript deals with information on the tendon to bone interface and tries to find out why a multiphasic scaffold is necessary to reproduce it and considerations that need to be taken into to make an ideal scaffold.

  • Management of mechanical ventilation is essential for patients with neuro-critical illnesses who may also have impairment of airways, lungs, respiratory muscles, and respiratory drive. However, balancing the approach to mechanical ventilation in the intensive care unit (ICU) with the need to prevent additional lung and brain injury, is challenging to intensivists. Lung protective ventilation strategies should be modified and applied to neuro-critically ill patients to maintain normocapnia and proper positive end expiratory pressure in the setting of neurological closed monitoring. Understanding the various parameters and graphic waveforms of the mechanical ventilator can provide information about the respiratory target, including appropriate tidal volume, airway pressure, and synchrony between patient and ventilator, especially in patients with neurological dysfunction due to irregularity of spontaneous respiration. Several types of asynchrony occur during mechanical ventilation, including trigger, flow, and termination asynchrony. This review aims to present the basic interpretation of mechanical ventilator waveforms and utilization of waveforms in various clinical situations in the neuro-ICU.

  • Current scintigraphic tests of gastrointestinal motor function provides relevant pathophysiologic information, but their clinical utility is controversial. Many scintigraphic methods are developed to investigate gastrointestinal motility from oral cavity to colon. These are esophageal transit scintigraphy, oropharyngeal transit study, gastric emptying test, small bowel transit time measurement, colon transit study and gastroesopahgeal reflux scintigraphy. Scintigraphy of gastrointestinal tract is the most physiologic and noninvasive method to evaluate gastrointestinal motility disorders. Stomach emptying test is regarded as a gold standard in motility study. Gastrointestinal transit scintigraphy also has a certain role in assessment of drug effect to GI motility and changes alter therapy of motility disorders. Scintigraphy provides noninvasive and quantitative assessment of physiological transit throughout the gastrointestinal tract, and it is extremely useful for diagnosing gastrointestinal motor dysfunction. This article reviews the current procedures, indications, significance and guidelines for gastrointestinal motility measurements by scintigraphy.

  • Chaotic dynamics have been studied by many researchers in the fields of biology, physics, and engineering. Interest in chaos is also expanding to the social sciences such as politics, economics, and others, including the prediction of societal events. The concept of leisure has developed from a passive concept correlated with relaxation, entertainment, and ideology formation into a positive concept that assumes a more active role. As information and communications technology develops, digital leisure activity is expected to continue spreading. This expansion of digital leisure function correctly, as well as. Traditional leisure activity functions correctly more, whereas digital leisure activity is predicted to function incorrectly more often. In this paper, we propose a mathematical addiction model of digital leisure that deals with its dysfunctions such as addiction to digital leisure, including computer games, internet search, internet chatting, and social media. Herein, to solve addiction to digital leisure, we propose a model derived from a nicotine addiction.

  • Tetrahydrobiopterin (BH4) is a multifunctional cofactor of aromatic amino acid hydroxylases and nitric oxide synthase (NOS) as well as an intracellular antioxidant in animals. Through regulation of NOS activity BH4 plays a pivotal role not only in a variety of normal cellular functions but also in the pathogenesis of cardiovascular and neurodegenerative diseases, which develop under oxidative stress conditions. It appears that a balanced interplay between BH4 and NOS is crucial for cellular fate. If cellular BH4 homeostasis maintained by BH4 synthesis and regeneration fails to cope with increased oxidative stress, NOS is uncoupled to generate superoxide rather than NO and, in turn, exacerbates impaired BH4 homeostasis, thereby leading to cell death. The fundamental biochemical events involved in the BH4-NOS interplay are essentially the same, as revealed in mammalian endothelial, cardiac, and neuronal cells. This review summarizes information on the cellular BH4 homeostasis in mammals, focusing on its regulation under normal and oxidative stress conditions.

  • Trigeminal neuralgia (TN) is neuropathic pain that affects the trigeminal nerve branches. Facial pain experienced by patients with TN is typically intense and excruciating. The second and third branches (maxillary and mandibular) are commonly affected. This case report focuses on the potential treatment options for acute TN attacks involving these branches. The proposed approach involves extra-oral peripheral blocks using local anesthetics. Pain levels were measured using a visual numeric scale (VNS) with potential side effects and other relevant documented information. The patients showed responses from high pain levels to almost complete remission (from 8 to 2 and from 10 to 2 on the final VNS), with no significant side effects. This technique provides immediate pain relief and complements oral medications by offering comfort and confidence until the desired drug effect is achieved.
