Variant formation and branching pattern of superficial palmar arch in a human cadaver: a case report
AbstractSuperficial palmar arch (SPA) is a dominant vascular structure in the palmar region that provides a major blood supply to fingers. Present case describes a rare formation and branching pattern of SPA in a formalin fixed cadaveric left hand. In this case, SPA was formed by the anastomoses between radial artery (RA) and the superficial brachioulnar artery (SBUA), which is defined as an ulnar artery with a high origin in the arm. More interestingly, unlike classic literature, SPA sends out six branches instead of four, and the principle artery of thumb arises directly from SPA instead of RA. The aforementioned variati...

Acute colonic flexures: the basis for developing an artificial intelligence-based tool for predicting the course of colonoscopy
AbstractTortuosity of the colon is an important parameter for predicting the course of colonoscopy. Computed tomography scans of the abdominal cavity were performed in 224 (94 female, 130 male) adult subjects. The number of acute (angle not exceeding 90 °) bends between adjacent colonic segments was noted and analyzed. Data were analyzed for correlation with gender, age, height and weight. An artificial intelligence algorithm was proposed to predict the course of colonoscopy. We determined the number of acute flexions in females to be 9.74 ±  2.5 (min–max: 4–15) and in males to be 8.7 ± 2.75 (min–max: 4–...

An evaluation of mandibular canal variations: a systematic review and meta-analysis
AbstractThe inferior alveolar nerve and vessels are carried via the mandibular canal, which extends bilaterally from the inferior alveolar foramen to the mental foramen. Bifid and trifid  mandibular canals result from abnormal fusions of nerve canals. The purpose of this study was to provide an up-to-date and comprehensive analysis of the prevalence of mandibular canal variations among healthy adults, and to identify any potential ethnic, sex, or laterality predilections. The pre valence of the bifid mandibular canal was 18.87% and that of the trifid canal 1.3%. Unilateral variants were three times commoner than bilater...

A surgical modification in the technique of rat pinealectomy
ConclusionAdvantages of this technique were removing a small skull area, modifying the hook insertion point to prevent damaging the brain veins, reducing the bleeding risk and the mortality rate. Surgery modification was associated with a decreased final number of animals used. Regardless of the melatonin shortage, pinealectomy affects different organs, which should be considered in the research study design. (Source: Anatomical Science International)
