background and objectives: primary acquired nasolacrimal duct obstruction (pando) is a common ocular problem. clinical presentation can range from simple tearing to a life-threatening condition. the exact pathophysiology of obstruction is not completely understood. in this study, therelationship between pando and nasal mucosal goblet cells was investigated.  materials & methods: in this ca...

The power requirement for a rotating parallel-disk assembly with through-flow is experimentally studied. The flow velocity at the test core exit is measured using a traverse hot-wire probe, from which the exit kinetic energy is determined. A traverse pitot tube is utilized to monitor the velocity distribution in the inlet duct from which the flow rate is evaluated. The total pressure characteri...

OBJECTIVE The aim of the study was to determine psychological, psychophysiological, and anthropometric factors connected with life events, level of depression, and quality of life in people at risk for cardiovascular disease and healthy controls. METHODS This is a cross-sectional study involving arterial hypertension patients and healthy controls. There were several measurements including phy...

CONTEXT The use of cranial osteopathic manipulative medicine (OMM) to alter cerebral tissue oxygen saturation could play a role in the maintenance of cerebral homeostasis. OBJECTIVE To examine the effects of cranial OMM on cerebral tissue oxygen saturation (S(CT)O(2)) and cardiac autonomic function in healthy adults. METHODS Cranial OMM augmentation and suppression techniques and sham thera...

careful treatment planning, space management, augmentation of bone and attention to the details of implant surgical and prosthetic techniques are important factors when treating anterior maxilla specially replacement of missing teeth. this case report addresses a chair-side ridge augmentation procedure using autograft bone harvested with trephine drills and placed without using screws and the f...

excessive alveolar bone resorption is commonly found when teeth are extracted. this is a problem in anterior part of mouth because it will result in an unaesthetic pontic on a narrow hollowed out alveolar ridge. yet, another problem is gingival recession and root exposure in adjacent teeth which represent a therapeutic problem to the clinician. use of acellular dermal matrix graft is an appropr...

Since there are no legally defined testing requirements for mobile positive pressure fans, they may be tested based on methods that do not correspond to their actual operating conditions. Adequate assessment of the technical and conditions this type equipment is particularly important used in rescue operations. Such units should characterized by efficient reliable operation. This article invest...

In terms of multifarious technical applications, various kinds passive methods are preferred to the active techniques when it comes increase amount convection heat transfer via less energy consumption. As a vortex generator within scope method, rib is usually employed induce enhancement. this study, rectangular cross-sectional ribs have been placed for staggered arrangement between horizontal p...

pancreatic stent proximal migration is a well known complication of pancreatic duct stenting, which occurs in about 5-6% of cases. serious complications should be avoided by retrieval of the stent via different endoscopic techniques. we report a new technique previously reported only once (in a pancreatic duct with underlying pathology), to remove the proximally migrated pancreatic stent in a n...
