chronic inflammatory demyelinating polyneuroradiculopathy (cidp) is an immune mediated disorder characterized by progressive developing or relapsing symmetrical motor or sensory symptoms in more than one limb over a period of two months. achalasia, as a primary esophageal motility disorder, is also characterized by increasing the tone of lower esophageal sphincter, absence or incomplete sphinct...

the vast majority of mandibular second molars have two roots with three root canals; however, variations in molar root canal anatomy are not uncommon. to the best of our knowledge, four rooted mandibular second molar with three mesial roots and one distal root has never been reported. herein, we present the endodontic management of a four rooted mandibular second molar tooth, diagnosed with the...

adenoid cystic carcinoma of the lung is a relatively rare, slow growing lung neoplasm. metastases outside the lung are uncommon. herein, we have reported the case of a patient who presented with a large mass in the right lower lobe of her lung. bronchial biopsy revealed features suggestive of adenoid cystic carcinoma of the lung with a predominant cribriform architecture. ct abdomen showed feat...

the main obstacle facing cancer preventive strategies worldwide is a lack of well conducted epidemiological studies to guide local and international efforts for disease control. in lebanon, long due political strain has added yet another obstacle to the development of methodologies aiming to collect data on cancer epidemiology. however, through several efforts dated from the 1960s the picture i...

Herein, a theoretical study on the stability of some vic-dioxime complexes of Ni(II), Pd(II) and Pt(II) in gas and aqueous phases is reported. The DFT/M06/SDD and DFT/M06/6-31G+(d,p) levels of theory were adopted for the metal ions and for every other element respectively. Structural analyses of investigated complexes have revealed square planar geometries stabilized by two O–H⋯Cl hydrogen bond...

This paper investigates the bending vibration of rotating single-walled carbon nanotubes (SWCNTs) based on nonlocal theory. To this end, the rotating SWCNTs system modeled as a beam with a circular cross section and the Euler-Bernoulli beam theory (EBT) is applied with added effects such as rotary inertia, gyroscopic effect and rotor mass unbalance. Using nonlocal theory, two coupled sixth orde...

Although central to regulating the access to genetic information, most lysine methyltransferases remain poorly characterised relative to other family of enzymes. Herein, we report new substrates for the lysine methyltransferase SETD6. Based on the SETD6catalysed site on the histone variant H2AZ, we identified similar sequences in the canonical histones H2A, H3, and H4 that are modified by SETD6...

The development of readily tunable and regioselective C-H functionalization reactions that operate solely through catalyst control remains a challenge in modern organic synthesis. Herein, we report that simple silver catalysts supported by common nitrogenated ligands can be used to tune a nitrene transfer reaction between two different types of C-H bonds. The results reported herein represent t...

Magnetic force microscope ( MFM ) is a powerful technique for mapping the magnetic force gradient above the sample surface. Herein, single-wall carbon nanotubes (SWCNT) were used to fabricate MFM probe by dielectrophoresis method which is a reproducible and cost-effective technique. The effect of induced voltage on the deposition manner of carbon nanotubes (CNT) on the atomic force microscope (...
