Slow motor units (MUs) have no sag in their unfused tetani. This study in anesthetized rats shows that the sag can be observed in slow soleus MUs after prolonged activity. Twitches and unfused tetanic contractions were recorded from male (n=35) and female (n=39) MUs before and after the four minutes of the fatigue test (trains of 13 pulses at 40 Hz repeated every second). After this activity tw...
During voluntary contraction, firing rates of individual motor units (MUs) increase modestly over a narrow force range beyond which little additional increase in firing rate is seen. Such saturation of MU discharge may be a consequence of extrinsic factors that limit net synaptic excitation acting on motor neurons (MNs) or may be due to intrinsic properties of the MNs. Two sets of experiments i...
Respiratory muscle weakness is common in children with neuromuscular disease (NMD). We hypothesized that weakness puts them at risk for respiratory muscle fatigue, a harbinger of chronic respiratory failure. We therefore measured a noninvasive index of respiratory muscle fatigue, the tension-time index of the respiratory muscles (TT(mus)), in 11 children with NMD and 13 control subjects. Spirom...
OBJECTIVE Doctors find patients with medically unexplained symptoms (MUS) challenging to manage and some hold negative attitudes towards these patients. It is unknown when and how these views form. This study examines medical trainees' beliefs and influences about MUS. METHODS Semi-structured interviews with 43 medical trainees. Using an iterative approach, initial emergent themes were explor...
INTRODUCTION Since the introduction of the first retropubic tension-free synthetic sling to treat stress urinary incontinence (SUI), newer approaches, different techniques and new devices have been created. Transobturator and single-incision sling (SIS) techniquespara-were developed with the goal of diminishing the rate of complications andspeeding the recovery phase. METHODS For this review ...
Musculoskeletal ultrasound (MUS) is potentially the most exciting development in clinical rheumatology practice in recent years. It is readily accessible, patient friendly and relatively inexpensive. It can be used to detect small joint effusions and thus increase the accuracy of diagnostic aspiration and therapeutic injection [1]. It is more sensitive than clinical examination in detecting ent...
Mid urethral sling is the standard in SUI treatment. Nevertheless, the risk of reoperation reaches 9%. There is no consensus as to the best treatment option for complications. A question is raised: what is the optimal way to achieve the best result in patients after primary failure? The aim of the study was to evaluate the outcomes of repeat MUS surgery in patients after excision of the sling w...
Monoclonal antibodies have been generated against disrupted mammary tumor viruses isolated from Mus musculus, Mus cervicolor, and Mus cookii. Monoclonal antibodies directed against the M.W. 36,000 external glycoproteins of these viruses demonstrate the presence of multiple epitopes, i.e., distinct antigenic determinants, within these glycoproteins. These epitopes represent type, group, and inte...
BACKGROUND Medically unexplained physical symptoms present one of the most common problems in modern medical practice but often prove difficult to manage. The central position of the GP in the care of patients with medically unexplained symptoms has been emphasized repeatedly, but little is known about the attitudes of GPs to this role. Understanding how GPs view these patients may inform the d...
The synthesis of derivatives of 4-Methylumbelliferone (4-MUs), which are structurally interesting antioxidants, was performed in this study. The modification of 4-Methylumbelliferone (4-MU) by different reaction steps was performed to yield the target compounds, the 4-MUs. The 4-MUs were characterized by different spectroscopic techniques (Fourier transform infrared; FT-IR and Nuclear magnetic ...
