The right brachioradial artery with the radial recurrent artery absence: a cadaveric case report.

Purpose: The purpose of this case report is to present an anatomical variation of the radial artery observed in anatomical practice and to discuss its clinical significance.

Methods: During the dissection of the right upper limb of a Chinese adult male, a high-position variation of the right radial artery with the absence of the radial recurrent artery was found.

Results: The variant branch of the right radial artery originates from the brachial artery and arises medially in the upper one-third of the arm.

Needle breakage as an unusual complication of intravenous therapy: A case report.

Residual intravenous foreign bodies following hand trauma are relatively rare; only a few previous reports of this situation are available. It has been reported that foreign bodies often migrate to the heart and atrium dextrum. Herein, we report a recent case of needle breakage in the dorsal vein of the hand that was removed with lignification using an intraoperative C-arm fluoroscopy machine and tape tourniquet to avoid proximal movement during removal.

More potential uses of specific perforator flaps in the calf - A cadaveric study on the subdermal vascular structure of the lower leg.

Background: The perforator flap has garnered significant interest since its inception due to its advantage of not needing a vascular network at the deep fascial level. Perforator flaps are commonly utilized in different flap transplant surgeries, and the thigh flap is presently the most widely used perforator flap. Is it possible for the calf to replace the thigh as a more suitable site for harvesting materials? Currently, there is a lack of relevant anatomical research.

The Diagnostic Value of Carnett's Test with Chronic Abdominal Pain: A Narrative Review.

Purpose Of Review: Chronic abdominal wall pain is a poorly recognized cause of chronic abdominal pain, and patients frequently go misdiagnosed despite a battery of medical tests. The Carnett's test is a diagnostic tool used to distinguish between abdominal wall pain and visceral pain. This review synthesizes the current literature on the Carnett's test, merges the viewpoints of diverse writers, and evaluates and reports on the Carnett's test's applicability.

Molecular and cellular pruritus mechanisms in the host skin.

Pruritus, also known as itching, is a complex sensation that involves the activation of specific physiological and cellular receptors. The skin is innervated with sensory nerves as well as some receptors for various sensations, and its immune system has prominent neurological connections. Sensory neurons have a considerable impact on the sensation of itching.

Anatomical Study of the Accessory Tendon of the Extensor Hallucis Longus Muscle and Its Clinical Application.

Backgroud: The accessory tendon of the extensor hallucis longus (ATEHL) muscle is a common abnormal structure, and its clinical significance remains debatable. In this study, we provide the incidence of the ATEHL and characterize its morphological types in Asian cadavers and investigate its clinical applications.

Methods: The tendons from 50 adult cadaveric feet, fixed in 10% formalin, were analyzed.

Mechanical/Electrical Characterization of ZnO Nanomaterial Based on AFM/Nanomanipulator Embedded in SEM.

ZnO nanomaterials have been widely used in micro/nano devices and structure due to special mechanical/electrical properties, and its characterization is still deficient and challenging. In this paper, ZnO nanomaterials, including nanorod and nanowire are characterized by atomic force microscope (AFM) and nanomanipulator embedded in scanning electron microscope (SEM) respectively, which can manipulate and observe simultaneously, and is efficient and cost effective. Surface morphology and mechanical properties were observed by AFM.

Long non-coding RNA SNHG1 promotes Cyclin D1-mediated proliferation in pancreatic cancer by acting as a ceRNA of miR-195.

Pancreatic cancer (PCa) is one of the most fatal cancers worldwide. Recently, many studies have confirmed that long non-coding RNAs (lncRNAs) play crucial roles in the development of many human cancers, including PCa. The purpose of the present study was to investigate the biological role and underlying mechanisms of lncRNA small nucleolar RNA host gene 1 (SNHG1) in PCa progression.

Frying Oil Evaluation by a Portable Sensor Based on Dielectric Constant Measurement.

A portable capacitive sensor was designed to assess frying oil degradation by measuring the changes in electrical capacitance. An interdigital electrode (IDE) was designed to be implemented as the testing probe (as IDEs are resistive to parasitic capacitance), together with an adjacent capacitive chip Pcap01 and a further microprocessor STM32, which were used as the data-processing elements. Experimental results demonstrated that viscosity could be a useful frying oil quality indicator, and also proved a preliminary correlation between IDE capacitance and oils' total polar materials.

Interactive Manipulation of Nonconductive Microparticles in Scanning Electron Microscope by a Virtual Nano-hand Strategy.

Micro/nano-manipulation is the fabrication of particular constructs on devices at the micro/nano-scale. Precise manipulation of microparticles is one of the key technological difficulties in manufacturing micro/nano-scale components. Based on scanning electron microscopy and nanomanipulator, this paper adopts a direct push method to operate randomly distributed microparticles into ordered structures.

Anatomical Study of the Compositions and Internal Connections of the Chiasma Plantare (Master Knot of Henry): Exploring Its Possible Clinical Impact.

The purposes of this study were to integrate the types of interconnecting fibers among components of the chiasma plantare and to deduce their flexion actions. The chiasma plantare and the long flexor tendons in 52 cadaveric feet (26 left feet and 25 right feet) were dissected and removed via gross anatomic dissection. The connections among the flexor digitorum longus (FDL), flexor hallucis longus (FHL), and quadratus plantae (QP) were then classified and analyzed.

MicroRNA-206 serves as a tumor suppressor in pediatric acute myeloid leukemia by targeting Cyclin D1.

Pediatric acute myeloid leukemia (AML) is a complex and heterogeneous disease. Several studies have shown the regulatory functions of microRNAs (miRNAs) in pediatric AML progression, and in this study, we aimed to evaluate the biological role of miR-206 in pediatric AML. The results demonstrated that miR-206 expression levels in the bone marrow and serum of pediatric AML patients were remarkably decreased than those in normal controls, and low serum miR-206 expression was closely associated with the unfavorable clinicopathological characteristics and prognosis of pediatric AML patients.

Anatomical basis of a proximal fasciocutaneous extension of the distal-based posterior interosseous flap that allows exclusion of the proximal posterior interosseous artery.

Objective: The objective of this study was to provide anatomical information for the repair of small tissue defects in the hand with posterior interosseous artery chain-link perforator flaps, a proximal fasciocutaneous extension of the distal-based posterior interosseous flap, which allows the exclusion of the proximal posterior interosseous artery.

Methods: Fourteen posterior interosseous artery chain-link perforator flaps taken from human cadavers were studied by the following three methods: latex perfusion for microanatomy analysis, denture material and vinyl chloride mixed packing for cast analysis, and latex perfusion for the production of clearance specimens. Statistical analysis was performed on cutaneous perforators coming from the intermuscular septum of the extensor carpi ulnaris and the extensor digitorum communis.
