C-terminal cross-linking telopeptide levels in COVID-19 patients: A prospective case-control study.

Background: Coronavirus disease 19 (COVID-19) is a viral infection mediated by coronavirus-2 that causes severe acute respiratory syndrome (SARS-CoV-2). The disease may affect biochemical parameters and electrolytes. C-terminal cross-linking telopeptide (CTX-I) is released during mature bone resorption and is a biomarker for predicting bone resorption.

Serum levels of heavy metals in patients with Bell's palsy: a case-control study.

Purpose: The exact etiology of Bell's palsy (BP) remains unknown, while its potential etiopathology includes neuritis and inflammation-related demyelination as in optic neuritis. It has been reported that disruption of heavy metal homeostasis may be associated with the inflammatory process of optic neuritis; therefore, heavy metals may be involved in the pathogenesis of facial nerve neuritis. In this study, we aimed to investigate serum levels of heavy metals including essential elements [iron (Fe), zinc (Zn), copper (Cu), cobalt (Co), and manganese (Mn)], and nonessential elements [lead (Pb) and cadmium (Cd)] in patients with BP.

There Is No Relation between Epitympanic Recess Volume and Chronic Otitis Media.

Background: Chronic otitis media is recurrent infection of the middle ear and mastoid air cells in the setting of perforation of the tympanic membrane. Risk factors for chronic otitis media include predisposing characteristics such as gender, allergies, Eustachian tube dysfunction, history of acute otitis media, and upper respiratory tract infection. The purpose of this study was to evaluate the potential relationship between chronic otitis media and epitympanic recess volume.

Determination and pharmacokinetic study of riociguat by UPLC-MS/MS in human plasma.

Pulmonary hypertension (PH) is frequent in the general population and is linked to an increased risk of death. Riociguat is a kind of endothelin receptor antagonist that is often used to treat PH. For pharmacokinetic studies and the determination of riociguat in PH patients, a new, quick, easy, and sensitive UPLC-MS/MS approach was designed and validated.

High Serum Progranulin Levels in COVID-19 Patients: A Pilot Study.

In this study, we aimed to determine whether the progranulin level in serum predicts the course and severity of the disease in COVID-19 (+) patients and whether it can be used as a biomarker in these patients. Therefore, we sampled 61 people infected with COVID-19, and the cases were divided into the following groups: asymptomatic, noncomplicated, moderate, and severe. Concentrations of progranulin, TNF-α, IL-6 from in serum obtained from all participants were measured using commercially available ELISA kits, as well as WBC, PLT, NE, LY, ALT, AST, Hb, PCT, and CRP were examined with clinical analyzer.

Evaluation of Serum Trace Element Levels and Biochemical Parameters of COVID-19 Patients According to Disease Severity.

The present study includes 60 people infected with COVID-19, and the cases were divided into the following groups: asymptomatic, mild, moderate, and severe. Serum Zn, Se, and Cu levels of these groups were analyzed by ICP-MS.

N-glycan profiling of papillary thyroid carcinoma tissues by MALDI-TOF-MS.

Papillary thyroid carcinoma (PTC) is a type of thyroid cancer whose incidence rate has increased recently all over the world. Glycosylation is a crucial post-translational modification (PTM) for the regulation of thyroid hormone synthesis in thyroid glands. However, our knowledge regarding the N-glycosylation change in PTC is limited.

Objective: Burn injuries are one of the most significant threats to life in both undeveloped and developing countries. In this study, we evaluate the demographic characteristics and treatment methods in pediatric burn cases admitted to our clinic.

Methods: A total of 960 patients aged 0-16 years old who were referred to our center with burn injuries between 2015 and 2016 were analyzed in terms of sex, age, etiology, epidemiology, burn percentage, the degree of burn, hospitalization duration, morbidity-mortality, and treatment methods.

Assessment of Vertical Triangular Spreader Graft Technique for Reconstruction of Middle Vault and Internal Nasal Valve Angle.

Background: Rhinoplasty is a surgical procedure to smooth out the nasal deformities and to fix nasal breathing problems. Spreader grafts and flaps are used to prevent some complications such as middle vault collapse, narrowing the internal nasal valve and inverted V deformity. To obtain more stable middle vault, spreader grafts and flaps could be used together.

Mean Platelet Volume, Red Cell Distribution Width, and Neutrophil-to-Lymphocyte Ratio Before and After Surgery in Patients With Carotid Body Tumors.

Objective: Carotid body tumors (CBTs) are rare hypervascular benign tumors that originate from the paraganglia at the carotid bifurcation. The red cell distribution width (RDW), neutrophil-to-lymphocyte ratio (NLR), and mean platelet volume (MPV) may serve as markers in inflammatory, cardiovascular, and neoplastic diseases. However, their prognostic value in CBTs is unknown.
