Lumbosacral Transitional Vertebrae: A Cadaveric Investigation of Prevalence and Relation to Lumbar Degenerative Disease

Conclusions: This cadaveric study aids in establishing the prevalence of LSTV (12.7%) in a random population and the frequency of the various Castellvi LSTV morphologies. An association was found between type Ia morphology and L4–L5 osteoarthritis which has not been reported in the past, suggesting that mild LSTV may carry more significance to lumbar pathology than previously considered.

The objective of this study was to evaluate the potential analgesic action of 8% capsaicin cream for topical use in patients with myofascial pain syndrome. METHODS: Initially, cream formulations of PLA (Placebo) and CPS (Capsaicin 8%) were developed and approved according to the current requirements of the health authority agency. The 40 participating patients were randomly assigned to the PLA and CPS groups in a double-blind fashion. Before the creams were topically administered, according to the allocation group, the local anesthetic was used for a period of 50minutes directly in the area of interest. The cream was a...

Publication date: Available online 14 September 2019Source: Thermochimica ActaAuthor(s): Akihiko TodaAbstractThe recrystallization behavior of poly(ethylene terephthalate), PET, in the melting region was examined by Fast-Scan and Temperature-Modulated Calorimetry. In addition to the prior results of Fast-Scan Calorimetry, FSC, evidence that recrystallization caused double PET melting peaks was obtained. An exothermic recrystallization peak was directly observed in the second heating run of FSC after the lower-temperature melting peak was eliminated through rapid heating and cooling. FSC was then performed with a temperatur...

The microstructure, corrosion behavior, and mechanical properties were analyzed. Electrochemical and immersion techniques were applied for corrosion behavior analysis. Moreover, scanning Kelvin probe force microscopy (SKPFM) was utilized to measure the surface Volta-potential. It was found that an increase in SR temperature decreased the strength by increasing the grain size and reduc...

In this paper, the growth of high-quality AlGaN epi-layer in AlGaN/GaN HEMT is reported. The optimization was carried out to improve surface morphology and quality of the AlGaN epi-layer to get high 2DEG (two-dimensional electron gas) properties of the HEMT structure...

To further improve its properties, a possible way is to form solid solutions by partially substituting one of constituting elements in MoAlB. This work reports on the synthesis of MoAl1-xSixB solid solutions by powder metallurgy. Influences of sintering temperature, dwelling time, and composition of starting mixture on the solubility limit of Si in MoAlB have been investiga...

There are many conditions that can be associated with elbow pain. Elbow pain is not usually a serious condition. Tennis Elbow Tennis elbow can also be referred to as lateral epicondylitis. Tennis elbow is an inflammation, soreness or pain on the outside (lateral) area near the elbow (Figure 1). The condition is usually seen in patients who perform manual labor or sports that require twisting and extension of the wrist against resistance. Tennis elbow is often associated with degeneration, irritation, tears and pain of the extensor tendons. Treatment: Treatment of tennis elbow includes ice, wearing an elbow pad, a decrea...

Total joint replacement surgery is among the most commonly performed inpatient procedures in the United States. More than 1,000,000 hip and knee replacements are performed each year, and, with the aging of our population, that number is expected to grow quickly. Despite the general success of such replacements, approximately 20 percent of recipients of well-done replacements are unsatisfied with their surgery, and unmet patient expectations for the procedure are typically an important cause of such dissatisfaction. In fact, one study found that the most important contributing factor to dissatisfaction following total knee ...
