Case Report: Ochronotic Arthropathy

Ochronosis is a rare metabolic disease caused by the deficiency of the homogentisic acid oxidase enzyme. It gives clinical findings related to the accumulation of homogentisic acid in soft tissues and excretion in urine. Patients with chronic arthropathy usually have some joint pain and inflammatory back pain. Although axial involvement radiologically resembles ankylosing spondylitis (AS), it is differentiated by the absence of typical syndesmophytes, facet involvement, sacroiliac erosion and fusion.Although there is no effective treatment for ochronosis disease; our patient was given a protein-poor diet, vitamin C supplementation (100 mg/kg/day) and analgesic treatment for symptoms recommended in the literature; and a reduction in joint complaints was observed. In this case, the aim is to diagnose the rare ochronotic arthropathy followed with the diagnosis of AS and to show that both axial and peripheral joint involvement can be together in this disease

A Survey on Energy Optimization Techniques in UAV-Based Cellular Networks: From Conventional to Machine Learning Approaches

Wireless communication networks have been witnessing an unprecedented demand due to the increasing number of connected devices and emerging bandwidth-hungry applications. Albeit many competent technologies for capacity enhancement purposes, such as millimeter wave communications and network densification, there is still room and need for further capacity enhancement in wireless communication networks, especially for the cases of unusual people gatherings, such as sport competitions, musical concerts, etc. Unmanned aerial vehicles (UAVs) have been identified as one of the promising options to enhance the capacity due to their easy implementation, pop up fashion operation, and cost-effective nature. The main idea is to deploy base stations on UAVs and operate them as flying base stations, thereby bringing additional capacity to where it is needed. However, because the UAVs mostly have limited energy storage, their energy consumption must be optimized to increase flight time. In this survey, we investigate different energy optimization techniques with a top-level classification in terms of the optimization algorithm employed; conventional and machine learning (ML). Such classification helps understand the state of the art and the current trend in terms of methodology. In this regard, various optimization techniques are identified from the related literature, and they are presented under the above mentioned classes of employed optimization methods. In addition, for the purpose of completeness, we include a brief tutorial on the optimization methods and power supply and charging mechanisms of UAVs. Moreover, novel concepts, such as reflective intelligent surfaces and landing spot optimization, are also covered to capture the latest trend in the literature.Comment: 41 pages, 5 Figures, 6 Tables.

Traumatic Central Cord Syndrome: A Case Report

WOS: 000270483500010The central cord syndrome is the most common type of the incomplete traumatic cervical cord syndromes. First described by Schneider in 1954, it is characterized by disproportionately greater motor impairment in the upper than in the lower extremities, bladder dysfunction, and varying degrees of sensory loss below the level of lesion. It has generally good prognosis for neurological and functional recovery. In this article, a 64-year-old male patient, diagnosed as central cord syndrome because of spinal cord injury is presented and discussed in the light of the relevant literature.

Acoustoelectric Effect on the Responses of SAW Sensors Coated with Electrospun ZnO Nanostructured Thin Film

In this study, zinc oxide (ZnO) was a very good candidate for improving the sensitivity of gas sensor technology. The preparation of an electrospun ZnO nanostructured thin film on a 433 MHz Rayleigh wave based Surface Acoustic Wave (SAW) sensor and the investigation of the acoustoelectric effect on the responses of the SAW sensor are reported. We prepared an electrospun ZnO nanostructured thin film on the SAW devices by using an electrospray technique. To investigate the dependency of the sensor response on the structure and the number of the ZnO nanoparticles, SAW sensors were prepared with different coating loads. The coating frequency shifts were adjusted to fall between 100 kHz and 2.4 MHz. The sensor measurements were performed against VOCs such as acetone, trichloroethylene, chloroform, ethanol, n-propanol and methanol vapor. The sensor responses of n-propanol have opposite characteristics to the other VOCs, and we attributed these characteristics to the elastic effect/acoustoelectric effect

Phylogenetic analysis of black queen cell virus and deformed wing virus in honeybee colonies infected by mites in Van, Eastern Turkey

This study aimed to determine the presence and prevalence of viral and parasitic infections causing high rates of colony loss in honey bee colonies in Van province, eastern Turkey. Twenty-six different apiaries were collected from five counties in Van province. These samples were tested by Reverse-Transcriptase PCR (RT-PCR) for acute bee paralysis virus (ABPV), chronic bee paralysis virus (CBPV), black queen cell virus (BQCV) and deformed wing virus (DWV). Selected positives were sequenced, phylogenetically analyzed and investigated in terms of Varroa. DWV and BQCV were identified in 69.23% (18/26) and 88.46% (23/26) of the bees respectively whereas ABPV and CBPV were not detected in the sampled apiaries. Results of the phylogenetic analysis of DWV and BQCV sequences showed 94-100% similarity to DWV and BQCV isolates obtained from Genbank. Prevalence of varroasis was 89% (23/26) in Van. The obtained samples were identified as Varroa destructor by morphological investigation. The study showed that viral and parasitic agents commonly infect honeybees in Van province, with high prevalence rates for BQCV and DWV. There was also a high degree of conservation of DWV and BQCV sequences distinct from DWV and BQCV isolates from other geographical regions. These findings, including current prevalence and phylogenetic analysis data for DWV, BQCV and varroazis in honeybees, are useful for future studies

Infective Endocarditis Presenting as Polymyalgia Rheumatica: Case Report

WOS: 000295972800010Infective endocarditis is a bacterial infection of the cardiac valves and endocardium with a high level of mortality and morbidity. Due to such high mortality and morbidity risks, early and accurate diagnosis bears great importance. Accordingly, for prevention of wrong or delayed diagnosis and treatment, it is important to know and be aware of diseases that can be mimicked by infective endocarditis and to keep such diseases in mind in the assessment and evaluation of the patient. In patients suffering from infective endocarditis, the disease may be accompanied by rheumatological symptoms and manifestations such as myalgia, arthralgia and arthritis. A review of the existing medical literature reveals a few cases of infective endocarditis mimicking polymyalgia rheumatica. In this article, we present a 64-year-old male case of infective endocarditis mimicking polymyalgia rheumatica without any known predisposing factor for infective endocarditis

The relation between vitamin D and postural balance according to clinical tests and tetrax posturography

WOS: 000378856200037PubMed ID: 27190466[Purpose] To evaluate the association between Vitamin D and risk of falling, balance, and lower extremity neuromuscular function in women aged 60 and above by using Tetrax posturography. [Subjects and Methods] A total 200 women were classified based on their 25-OH-vitamin D (25(OH)D) values: hypo-vitaminosis group (less than 50.0 nmol/l) and normal group (50.0 more). Balance was measured using a Tetrax (R) posturography device (Sunlight Medical Ltd, Israel). Falling risk, stability index (SI), and weight distribution index (WDI) were calculated. Short Physical Performance Battery (SPPB) and International Physical Activity Questionnaire (IPAQ) were used as the clinical tests. [Results] Standing balance, gait, chair stand performance and total SPPB scores were significantly better in the patients with serum 25(OH) D levels higher than 50.0 nmol/l. Similarly, falling risk and SI values in the most of the postures were significantly higher in the hypovitaminosis group. There were significant associations between serum 25(OH) D levels with SPPB total score and Tetrax-measured falling risk. [Conclusion] This study showed better balance control, lower extremity function, and reduced falling risk in patients with serum 25(OH) D levels higher than 50.0 nmol/l in women aged 60 and above
