levels (75.10 U/mL). Sigmoidoscopy was performed, showing a polypoid, fungating mass with colonic obstruction in the rectum, located 11 cm from the anal verge (Fig. A). Chronic inflammation with ulceration and epithelial hyperplasia were observed in the mucosal layer of endoscopic biopsies. A CT scan of the abdomen and pelvis revealed an illdefined enhancing lesion in the rectum, abutting the u...

Hedgehog (Hh) signalling plays an important role in various developmental processes by activating the Cubitus interruptus (Ci)/Glioblastoma (Gli) family of transcription factors. In the process of proper pattern formation, Ci activity is regulated by multiple mechanisms, including processing, trafficking, and degradation. However, it remains elusive how Ci distinctly recognizes the strong and m...

Resection of retroperitoneal tumors is usually performed using the anterior retroperitoneal approach. Our report presents an innovative method utilizing a robotic surgical system. A 50-yr-old male patient visited our hospital due to a known paravertebral mass. Magnetic resonance imaging showed a well-encapsulated mass slightly abutting the abdominal aorta and left psoas muscle at the L4-L5 leve...

Numerous industrial applications, particularly those in the transport industry, require joining of dissimilar materials which offers considerable benefits terms low cost, design flexibility, and weight reduction for overall structures. The problems associated with conventional fusion welding processes have stimulated researchers recent years to develop new methods are difficult join. Friction s...

introduction: the use of cell phones is widespread and there are public concerns regarding its possible deleterious effects on human health especially on the pregnancy outcomes. in this study, structural changes of the placenta after applying the cell phone radiation were examined in the mice model.   materials and methods: for this work, 40 pregnant balb/c mice were randomly allocated to one c...

regarding the importance of rice fields, as the main mosquito breeding places, use of chemical larvicides has been under consideration in malaria eradication programs. in this trial, oms 786 was used, to study the method and cost of application of this larvicide in the rice fields. two form of larvicides (1% sand granule, and 50% e.c.) were used in four formulations. (10 and 15 kg. of 1% s.g./h...

background: men are unavoidably exposed to ambient electromagnetic fields (emf) generated from various electrical gadgets and from power transmission lines. prostate gland plays an important role in secretion of semen as largest accessory gland of male reproductive system. it seems that protection of this gland against emf is important in spermatogenesis process. objective: the goal of this stu...

This paper describes the “motion” properties of the ambiyopic fovea and compares them to the normal periphery. Specifically, thresholds for defection of the displacement of a grating pattern, and for discrimination of displacement direction were measured. The main findings of these experiments were: (I) in the central vision of both normal and amblyopic observers, unreferenced displacements are...

We have found a new configurational effect in texture segmentation. In addition to collinear facilitation at the edge, this effect results from contextual modulation within the texture-region, i.e. from texels not abutting the segmented edge. The largest facilitation was found when two conditions were fulfilled: (i) elements along the edge were parallel to the edge and collinear, (ii) elements ...
