Background: One of the most common complications of total thyroidectomy is post-operative transient or persistent hypoparathyroidism that can cause symptomatic hypocalcaemia. To prevent this complication, shorten the period of hospitalization and reduce morbidity, routine supplementation of oral vitamin D and calcium has been suggested. This systematic review and meta-analysis aims to critically assess the association between pre-operative calcitriol supplementation and post-operative hypocalcaemia.

This paper is an attempt to provide a dual-source inverter, an intelligent inverter topology that links two isolated DC sources to a single three-phase output through single-stage conversion. The converter is designed to be utilized in hybrid photovoltaic fuel cell systems, among other renewable energy applications. The proposed dual-source inverter employs a single DC-AC converter, as opposed to conventional dual-source hybrid inverters which make use of several input DC-DC modules to obtain the voltage formed across the inverter's input DC-link.

Introduction: Differentiating the soft tissue abscess from other types of skin and soft tissue infections (SSTIs) poses a particular challenge because they have similar physical evaluation findings, but each disease has a different course, outcome, and treatment. This meta-analysis aimed to investigate the diagnostic accuracy of point-of-care ultrasonography for diagnosis of soft tissue abscess in the emergency departments.

Methods: A comprehensive literature search of MEDLINE, Scopus, Web of Science, Embase, and Google Scholar, from inception to January 2023, was conducted to identify relevant studies investigating the diagnostic performance of point-of-care ultrasonography for identification of abscess.

Nanocomposite Based on HA/PVTMS/ClFeHO as a Gas and Temperature Sensor.

Sensors (Basel)

December 2022

Faculty of Mechanical Engineering and Design, Kaunas University of Technology, Studentu Street 56, 51373 Kaunas, Lithuania.

In this paper, a novel nanocrystalline composite material of hydroxyapatite (HA)/polyvinyltrimethoxysilane (PVTMS)/iron(II)chloride tetrahydrate (ClFeH-O) with hexagonal structure is proposed for the fabrication of a gas/temperature sensor. Taking into account the sensitivity of HA to high temperatures, to prevent the collapse and breakdown of bonds and the leakage of volatiles without damaging the composite structure, a freeze-drying machine is designed and fabricated. X-ray diffraction, FTIR, SEM, EDAX, TEM, absorption and photoluminescence analyses of composite are studied.

Article Synopsis
  • * A thorough search of existing literature resulted in 26 relevant studies, revealing that MRI has a high sensitivity of 92% and specificity of 98% for diagnosing AA in this population.
  • * The findings suggest that MRI should be the preferred imaging technique for suspected AA in pregnant women, particularly when ultrasound results are unclear, potentially reducing unnecessary surgeries.

Intensive chemical herbicide use has resulted in human health and environmental issues. This study evaluated the phytotoxic potential of chamomile extract as a bioherbicide to minimize chemical herbicide use in wheat production. Treatments including four concentrations (0, 50, 100, and 150 mL/L) of three different chamomile plant parts (root, shoot, and root + shoot) extracts were applied to flixweed as a major weed in wheat production.

Background: Multiple sclerosis (MS) is a complex autoimmune disease of the central nervous system (CNS) with unknown etiology and variable clinical evolution. Although the role of serum progranulin levels in the pathogenesis of MS remains unclear, it is well known that progranulin is involved in several physiological and pathophysiological process of CNS including modulation of neurite outgrowth, neuronal differentiation, and neuronal survival. Therefore, in this study, we aimed to measure serum levels of progranulin in patients with neuromyelitis optica (NMO) and relapsing-remitting multiple sclerosis (RRMS) in comparison with healthy control subjects.

Multiple sclerosis (MS) is an autoimmune disease of central nervous system. Since different types of immune cells are involved in MS pathogenesis, in this study we aimed to evaluate serum levels of several immunological components including soluble CD4 (sCD4), sCD8, sCD163, and immunoglobulins as markers of activity of T-cells, macrophages, and B-cells in different types of MS. Serum levels of sCD4, sCD8, and sCD163 of patients with relapsing-remitting MS (RRMS, n=61), primary progressive MS (PRMS, n=31), secondary progressive MS (SPMS, n=31), clinical isolated syndrome (CIS, n=31) and neuromyelitis optica (NMO, n=31), and healthy controls (n=49) were measured using enzyme-linked immunosorbent assay (ELISA).
