Conductometric Flexible CuO-Based Sweat-Loss Monitoring Sensor for Future Wearable Technology in Healthcare.

Healthcare tracking supports early diagnosis of illnesses, real-time tracking of the impacts of therapy and treatment, and tracking of cases of human health. Based on this, real-time tracking of sweat loss provides an easy, convenient, and noninvasive approach to the early diagnosis of physical illness in individuals. To date, copper oxide (CuO) as a nanostructured semiconductor metal-oxide is regarded as a hopefully p-type sensing material.

Nanostructured CuO Thin-Film-Based Conductometric Sensors for Real-Time Tracking of Sweat Loss.

Enhanced sweat sensors lead to real-time, sustained, noninvasive tracking of sweat loss, ensure insight into individual health conditions at the molecular level, and have obtained prominent interest for their hopeful implementations in customized health tracking. Metal-oxide-based nanostructured electrochemical amperometric sensing materials are the best selection for continuous sweat monitoring devices owing to their high stability, high-sensing capacity, cost-effectiveness, miniaturization, and wide applicability. In this research, CuO thin films have been fabricated by successive ionic layer adsorption and reaction technique (SILAR) with and without the addition of L.

Cabazitaxel's ototoxicity: An animal study and histopathologic research.

Introduction: Chemotherapeutic agents can have both serious side effects and ototoxicity, which can be caused by direct toxic effects or by metabolic derangement by the agents. Cabazitaxel (CBZ) is a next-generation semi-synthetic taxane derivative that is effective in both preclinical models of human tumors that are sensitive or resistant to chemotherapy and in patients suffering from progressive prostate cancer despite docetaxel treatment. The primary aim of this study is to investigate the ototoxicity of CBZ in a rat model.

Ototoxicity of Triclosan: A Rat Model Study.

Experimental Analysis and Multiscale Modeling of the Dynamics of a Fiber-Optic Coil.

Fiber-optic gyroscopes (FOGs) are common rotation measurement devices in aerospace applications. They have a wide range of diversity in length and in the winding radius of the coil to meet system requirements. Every dimensional parameter in the coil influences the dynamic response of the system, eventually leading to measurement errors.

Comparison of the Healing Effect of Nasal Saline Irrigation with Triamcinolone Acetonide Versus Nasal Saline Irrigation alone in COVID-19 Related Olfactory Dysfunction: A Randomized Controlled Study.

There is no routinely determined treatment for olfactory dysfunction because of COVID-19. Saline irrigation and nasal corticosteroid treatments are safe and inexpensive methods, and have low side effects. In our study, we argue that saline nasal irrigation and topical corticosteroid treatment can be used in the treatment of patients with olfactory loss in all areas of rhinology.

Objective: PFAPA syndrome is derived from the initials of the English words of the findings that make up the syndrome ("Periodic Fever", "Aphthous Stomatitis", "Pharyngitis", "Adenitis"). This study aims to evaluate the vestibular system in patients with PFAPA syndrome by the cVEMP test and to give a general review of PFAPA syndrome in light of current literature.

Methods: In this prospective study, 30 patients aged 4-6 who were diagnosed with PFAPA in a tertiary pediatrics clinic, between January 2016 and February 2020 and 30 children of the same age group who applied to a tertiary otorhinolaryngology clinic for other reasons and proven to have no hearing or vestibular problems were included and in addition to routine physical examination, electromyographic activity of the sternocleidomastoid muscle surface was measured.

The Effect of Nasal Steroid and Antihistamine Use on Total Oxidative Stress and Antioxidant Status in the Treatment of Allergic Rhinitis.

Introduction: The purpose of this study is to determine the post-treatment levels of total oxidant status (TOS) and total antioxidant status (TAS), that are increased due to pathophysiology, and to compare those with pre-treatment levels in allergic rhinitis patients. Among 84 patients clinically diagnosed with allergic rhinitis, 31 patients were started only on nasal steroid treatment (mometasone furoate), and 53 patients were started on nasal steroid and oral antihistamine treatment (mometasone furoate + rupatadine fumarate 10 mg). Blood samples were taken from the patients at the first examination and at post-treatment month 1.

Rhinoliths: Analysis of 24 Interesting Forgotten Foreign Body Cases.

Rhinoliths are petrified masses formed by accumulation of endogenous or exogenous salts around a nidus. Although rarely formed by the body, the most common cause is foreign bodies forgotten in the nose at childhood. Rhinoliths are rare and have been reported as a single case report in the literature.

Objective: Osteoporosis is a common metabolic disorder that causes progressive changes in bone structure. Metabolic changes and possible degeneration of middle ear ossicles or the cochlear capsule may cause hearing loss in patients with osteoporosis. The aim of this study was to evaluate the hearing function and otolaryngologic symptoms of patients with osteoporosis.

Facial paralysis and mediastinitis due to odontogenic infection and poor prognosis.

Cervical necrotizing fasciitis (CNF) is a rare, rapidly advancing infection that involves the skin, the subcutaneous fibrofatty tissue, as well as the superficial and deep fascia and can cause life-threatening complications. The most frequent initiating factors in the head and neck region are a primary odontogenic infection, a peritonsillar infection, as well as posttraumatic or iatrogenic skin and mucosal injuries. Necrotizing fasciitis (NF) can expand within hours, and the reported mortality rate is up to 75% with delay interference.

Fifty two ears of 26 patients who had unilateral tinnitus were included into the retrospective study.

The effect of retinyl palmitate on healing of benign vocal fold lesions.

The leading cause of vocal fold lesions such as nodules and polyps is phonotrauma, which causes microhematoma formation in the vocal fold cover that can initiate an inflammatory process. Vitamin A (Vit A) is essential for immunity, cellular differentiation and maintenance of respiratory epithelium. The aim of this study is to investigate the effect of Vit A (retinyl palmitate) on healing of vocal fold lesions, including vocal polyps and nodules.
