Conflicts of interest: The authors have declared no conflicts of interest. by hairdressers to straighten curly hair, have recently become fashionable in hair salons. They are generally based on formaldehyde, which alters hair keratins in order to provide a smoothing effect on frizzy hair. The treatment process usually includes three tasks: (i) applying the product to the hair, (ii) blow-drying ...

Inserting a guiding catheter into a tortuous artery for neurointerventional procedures can be difficult. In our technique, the carotid artery is manually compressed to stabilize and/or straighten the inserted wire before advancing the guiding catheter. Although this technique is not risk-free and care must be taken to avoid vascular injury by excessive compression, it is useful for the insertio...

Radiofrequency neurotomy (RFN) of the medial branches (MB) of the lumbar dorsal rami is a common procedure to treat facetogenic backache. Serious complications are unusual when guidelines are followed (1). We report for the first time, the development of severely painful camptocormia (inability to straighten the back in the upright position that disappears in the recumbent position) as a compli...

We present a molecular dynamics simulation study of crystal nucleation from undercooled melts of n-alkanes, and we identify the molecular mechanism of homogeneous crystal nucleation under quiescent conditions and under shear flow. We compare results for n-eicosane (C20) and n-pentacontahectane (C150), i.e., one system below the entanglement length and one above, at 20%-30% undercooling. Under q...

An effective chromosome image processing algorithm for straightening highly curved chromosomes is presented. This will extend the domain of application of most of the previously reported algorithms to the curved chromosomes. The proposed algorithm is based on the calculating and analyzing the vertical and horizontal projection vectors of the binary image of the chromosome obtained at various ro...

DESCRIPTION A 71-year-old right-hand-dominant retired man complains of inability to straighten the thumb, middle finger, and small finger of his left hand. This symptom has been progressively worsening over the past 2 or 3 years. On examination, the 3 affected digits cannot be fully extended, either passively or actively. There is a thick band of fibrous tissue tethering each digit in its contr...

A stainless steel grid baked by a propane±air premixed ¯ame had iron, chromium and nickel oxide deposits on the grid surface. With this grid, entangled and curved shape multi-walled carbon nanotubes (MWNTs) were harvested from an ethylene±air di€usion ¯ame with yield rate of 3 mg/min. Nitrogen addition to the ¯ame was found to straighten the entangled tubes probably by lowering the ¯ame tempera...

A patient is described with a right-sided tortuous siphon-like extracranial internal carotid artery leading to highly distressing ipsilateral heart beat synchronous pulsatile tinnitus, scoring 9/10 measuring loudness. Dilating the balloon during the occlusion test in or distal to the siphon-like anomaly reduces the arterial pulsations. Subsequently, surgery is performed using Teflon as an exter...
