INTRODUCTION: The aim of this study was to determine the correlation between muscle thickness (MT) and cycling power in varsity cyclists using ultrasonography (US) and to identify any differences in MT between short- and long-distance cyclists. MATERIALS AND METHODS: Twelve cyclists participated in this study. Real-time two-dimensional B-mode US was used to measure the MT in the anterior thigh, anterior lower leg, and trunk, especially in the abdominal and lumbar regions...

INTRODUCTION: Posterior spinal arteries (PSAs) arise from the vertebral (VA) or posterior inferior cerebellar (PICA) artery. We identified variations in their origins and their anastomosis with the first posterior radiculomedullary branches in human spinal cords. MATERIALS AND METHODS: Spinal cords from male and female cadavers (n = 30) were injected with colored latex through the vertebral, ascending cervical, costocervical trunk and segmental arteries. Specimens were fixed in formalin and the spinal arteries were dissected under a surgical microscope...

One branch of the radial nerve to the medial head of the triceps brachii muscle (MHN) has been described as accompanying or joining the ulnar nerve. Mostly two MHN branches have been reported, with some reports of one; however, the topographical anatomy is not well documented. We dissected 52 upper limbs from adult cadavers and found one, two, and three MHN branches in 9.6%, 80.8%, and 9.6% of cases, respectively. The MHN accompanying the ulnar nerve was always the superior MHN. The relationship between the ulnar nerve and the MHN was classified into four types according to whether the MHN was enveloped along with the ulnar nerve in the connective tissue sheath and whether it was in contact with the ulnar nerve...

INTRODUCTION: The purpose of the present study was to investigate the presence of an elongated transverse aortic arch (ETA), which has been reported to be specific for Turner syndrome, in a population without Turner syndrome. MATERIALS AND METHODS: A set of 1012 patients (713 men, 299 women) under 40 years old, who underwent thoracic CT examination in our radiology department between July 2016 and December 2016, were included in the study. CT scans were performed by 16-slice scanners...

INTRODUCTION: There is no standardized approach to the greater occipital nerve (GON) block technique for treating occipital neuralgia. The aim of the present study was to validate the previously-suggested guidelines for conventional injection techniques and to provide navigational guidelines for safe GON block. METHODS & MATERIALS: The GON, lesser occipital nerve (LON) and occipital artery (OA) were carefully dissected in the occipital region of embalmed cadavers...

The mammalian target of rapamycin, mTOR, is a serine-threonine protein kinase downstream of the phosphatidylinositol 3-kinase (PI3K)-AKT axis. The pathway can regulate cell growth, proliferation, and survival by activating ribosomal kinases. Recent studies have implicated the mTOR signaling pathway in ovarian neoplasms, polycystic ovary syndrome (PCOS) and premature ovarian failure (POF). Preclinical investigations have demonstrated that the PI3K/AKT/mTOR pathway is frequently activated in the control of various ovarian functions...

INTRODUCTION: Variations of testicular vessels are more common than supposed. The testicular artery varies because of abnormal regression of the lateral mesonephric arteries in the fetus, whereas variations in the testicular vein are due to abnormalities in the involution of the intersubcardinal anastomosis. Such variations are usually found incidentally during surgical procedures around the renal pedicle and they often lead to complications. Several authors have attempted to classify them...

Introduction When surgeons operate on the foot and ankle, the most common complication that may arise is injury of the cutaneous nerves. The sural nerve (SN) is potentially at risk of being injured when treating fractures involving the distal tibia using the posterolateral approach. The aim of this study was to evaluate how differences in length and position of the surgical treatment of fractures involving the distal tibia can affect the risk of SN injury. Materials and Methods The study involved 40 healthy volunteers (n=80 lower limbs)...

INTRODUCTION: The aim of this work was to conduct a radiological micro-CT study and meta-analysis to determine the morphological features of the root canal anatomy of the maxillary molars. MATERIALS AND METHODS: The radiological study included micro-CT scans of 110 maxillary first molars and 98 maxillary second molars. To identify articles eligible for inclusion in our meta-analysis, PubMed, Embase, and Web of Science were search comprehensively. The following data were extracted: study type (cadaveric, intraoperative or imaging), Vertucci types of canal configuration, presence/number of canals, roots, apical foramina, apical deltas, and inter-canal communications...

In this study, the protective effect of spirulina on corneal injury after formaldehyde (FA) exposure was assessed. Thirty adult male albino rats were divided into four groups. Group I: twelve rats were divided into two subgroups: I-a (negative control) and I-b (positive control). Group II (spirulina group): six rats received spirulina via an oral gavage feeding needle at a daily dose of 400mg/kg b.w. Group III (FA exposure group): six rats were subjected to 10% FA inhalation for two hours per day for two weeks (five days per week)...

An estimated 1.4% of the population worldwide has been diagnosed with Gender Dysphoria, as defined by the Diagnostic and Statistical Manual of Mental Disorders. Gender reassignment, which holistically encompasses psychotherapy, hormonal therapy and genital and nongenital surgeries, is considered the most effective treatment for transgender non-conforming patients afflicted with gender dysphoria. Little research is currently available identifying the psychosocial needs of the transgender population and their access to preventative and primary care during this transitioning process...

The handedness of Michelangelo Buonarroti (1475-1564), one of the greatest artists of all time, is still controversial. Although there is no doubt that almost all of his well-attributed drawings were drawn with the right hand, the hatch marks of the shading going downward from right to left; it has been often neglected in the literature that he was an innate left-hander. An unfairly unknown autobiography of Raffaele da Montelupo stated that Michelangelo, a natural left-hander, trained himself from a young age to become right-handed...

INTRODUCTION: Difficulty in identifying the susprascapular nerve (SSN) limits the success of US-guided regional anesthetic injections. A proximal SSN block could be an effective and reliable approach. The primary objective was to validate the feasibility of the US-guided proximal SSN block. The secondary objective was to quantify the spread of the colored local anesthetic to the phrenic nerve (PN). MATERIALS AND METHODS: Fourteen brachial plexuses from seven cadavers were included...

INTRODUCTION: Carpal Tunnel Syndrome (CTS) is the most common upper extremity entrapment neuropathy and various risk factors have been implicated in the etiology. In this study, we aimed to determine whether anthropometric measurements are independent risk factors for CTS. MATERIALS AND METHODS: Patients with symptoms of CTS (n= 27) and asymptomatic controls (n=27) were enrolled following electrophysiological confirmation. Body mass index (BMI) was recorded and anthropometric measurements of the hand were made by a digital caliper...

INTRODUCTION: Bicuspid aortic valves are associated with histopathological abnormalities of the aorta. Their diameters have been measured in several studies, but the literature concerning changes in the overall anatomy of the ascending aorta is limited. We wanted to know whether the anatomy of the valve, bicuspid or tricuspid, is associated with anatomical differences. MATERIALS AND METHODS: We prospectively included patients requiring aortic valve surgery. The protocol included a chest CT scan before the operation to determine the angulations and straight lengths of aortic segments 0 and 1...

INTRODUCTION: Epicardial electrophysiological procedures rely on dependable interfacing with the myocardial tissue. For example, epicardial pacing systems must generate sustainable chronic pacing capture, while epicardial ablations must effectively deliver energy to the target hyper-excitable myocytes. The human heart has a significant adipose layer which may impede epicardial procedures. The objective of this study was to quantitatively assess the relative location of epicardial adipose on the human heart, in order to define locations where epicardial therapies might be performed successfully...
