SIR,-A man aged 40 was admitted in July 1967 with a reducible right inguinal hernia and an undescended left testis. The right testis, normal in size and consistency, was present in the scrotum. Exploration of the right inguinal canal revealed a completely patent processus vaginalis with the testis inside the sac. On applying traction to the testis, an oval mass, apparently intra-abdominal, was ...

The laryngeal tube suction II (LTS-II; VBM, Medizintechnik GmbH, Sulz, Germany) is a recent version of the laryngeal tube (LT) family of supraglottic airway devices originally intended for emergency airway management including out of hospital use 1,2 and unexpected difficult airway situations 3,4, but which are currently also used during general anaesthesia 5-11. The original LT consists of an ...

In case of hepatic damage, the liver uses a unique regeneration mechanism through proliferation of hepatocytes. If this process is inhibited, bipotent oval stem cells proliferate and differentiate to hepatocytes and bile ducts, thus restoring liver mass. Although oval cell accumulation in the liver is often associated with inflammatory processes, the role of lymphocytes in oval cell-mediated he...

Introduction Placement of a bougie for sleeve sizing during laparoscopic sleeve gastrectomy (LSG) is recommended. We compared this standard with a suction calibration system (SCS) that performs all functions with one insertion, and measured each step’s duration. Methods Primary LSG was performed using a bougie and SCS in alternating order. Number of tube movements to achieve optimal placement, ...

PURPOSE To evaluate the cement thickness around oval and circular posts luted in oval post spaces prepared with different drills/tips. METHODS Extracted premolars were endodontically treated and obturated, then randomly divided into three groups (n = 5) according to the tips/drills used for post-space preparation and to the type of fiber post luted: medium grit oval tip + oval posts, fine gri...

Preliminary note The main goal of each technologist is the prediction of technological parameters by fulfilling the set design and technological demands. The work of the technologist is made easier by acquired knowledge and previous experience. A plan of input-output data was made by using the hybrid system of modelling ANFIS (Adaptive Neuro-Fuzzy Inference System) based on the results of seam ...

Improved inclusion-exclusion inequalities for unions of sets are available wherein terms usually included in the alternating sum formula can be left out. This is the case when a key abstract tube condition, can be shown to hold. Since the abstract tube concept was introduced and refined by the authors, several examples have been identified, and key properties of abstract tubes have been describ...

tions and advantages of this method have been reported (Barber, J. MIilk & Food Technol., 12, 257-266, 1949), and it is well to point out here the obvious economy in incubator space, agar medium, time, and productivity. Usually, 4 to 5 ml of agar are used per tube. Samples (1 ml or some fraction thereof) aire added to the sterile, melted, and tempered agar; the tubes are agitated gently, slante...
