fusion is an anomaly manifested in both deciduous and permanent dentitions. fu- sion of dental tissues in the primary dentition is of clinical significance owing to the challenges in treatment of the affected teeth and aberrations encountered in development and eruption of their successors. triple tooth refers to the :union: of three separate tooth entities. it can occur by fusion, germination,...

original article   mental fatigue (mf) is considered as a contributor factor in incident, even catastrophic one. electroencephalography measurement has been the most acceptable method to assess mf by neurologists. however, this method could be hardly feasible in real work setting. flicker fusion device, by contrast, is more usable at work setting. the purpose of this study was to compare the cr...

background: controlling the hemodynamic situation of patients who have spinal operation is of prime importance, and maintaining the heart rate and blood pressure in normal or low- normal levels in these patients can reduce their bleeding loss. one of the commonly used drugs for this purpose is remifentanil. another sedative-hypnotic-analgesic drug, with acceptable effects is dexmedetomidine. th...

Extending and improving the concepts: woven frame and fusion frames, we introduce the notion of woven fusion frames in Hilbert spaces. We clarify our extension and generalization by some examples of woven frames and woven fusion frames. Also, we present some properties of woven fusion frames, especially we show that for given two woven frames of sequences, one can build woven fusion frames and ...

Sirenomelia is a rare congenital malformative disorder characterized by fusion of the lower limbs giving a characteristic mermaid-like appearance to the affected foetus. We report a case of sirenomelia occurring in a 19 year old Cameroonian woman following premature rupture of membranes and associated cord prolapse. This is the first documented case in this country. We highlight some of the cul...

objective(s) staphylococcus aureus is a foremost source of numerous nosocomial and community acquired infections. antibiotic therapy for vancomycin resistant s. aureus (vrsa) can not promise the eradication of infections. since adhesion is the major route of infections, adhesin based vaccine could suppress s. aureus infections. fibronectin binding protein a (fnbpa) and clumping factor a (clfa) ...

In recent years, laboratory studies of cultural evolution have become increasingly prevalent as a means of identifying and understanding the effects of cultural transmission on the form and functionality of transmitted material. The datasets generated by these studies may provide insights into the conditions encouraging, or inhibiting, high rates of innovation, as well as the effect that this h...

We discuss the importance of narrative intelligence (story-awareness, story-telling, historical grounding) in regard to an agent’s transcendence of its immediate local temporal context to create a broad temporal horizon in which the experience and future of the agent can be accounted for, together with the advantage that narrative provides to sociality by making the experience of others availab...

Errors occur commonly in healthcare and can cause significant harm to patients. Most errors arise from a combination of individual, system, and communication failures. Neurologists may be involved in harmful errors in any practice setting and should familiarize themselves with tools to prevent, report, and examine errors. Although physicians, patients, and ethicists endorse candid disclosure of...
