Spindle cell lipoma and pleomorphic lipoma emerge as benign, adipocytic neoplasms representing a morphologic continuum of a singular neoplasm. In addition to myofibroblastoma and cellular angiofibroma, spindle cell lipoma or pleomorphic lipoma configures as a constituent of chromosome 13q/RB1 family of tumors. Initially scripted by Enzinger and Harvey in 1975 with an obsolete terminology of dendritic fibromyxolipoma, aforesaid adipocytic neoplasms articulate an estimated 1.5% of lipomatous tumors. In contrast to conventional lipoma, spindle cell lipoma or pleomorphic lipoma is an uncommonly discerned variant, demonstrating a proportion of 1: 60.

Hypertension is a risk factor for the development of heart failure and has a negative impact on the survival of these patients. Although patients with these two conditions usually take different antihypertensive medications, some patients do not achieve adequate blood pressure control and their hypertension becomes resistant or refractory. In this scenario, percutaneous renal denervation has emerged in recent years as an alternative to achieve blood pressure control goals. We present the case of a 53-year-old woman with a medical history of essential hypertension, hypercholesterolemia, unipolar depression, and diabetes, who was diagnosed with dilated cardiomyopathy with reduced left ventricular ejection fraction (33%). Despite the initiation of multiple antihypertensive medications and placement of a cardiac resynchronization therapy pacemaker, the patient remained hypertensive with a left ventricular ejection fraction of 40%. At that time, percutaneous renal denervation was performed without complications, and one year after the procedure, the patient had improved better blood pressure control and the left ventricular ejection fraction increased to 51%. This case illustrates one of the clinical scenarios in which it has been suggested that renal denervation may be more beneficial, as in the situation of patients with refractory hypertension and heart failure.

The aim of the study was to evaluate ozone therapy in obese pregnant women. 118 pregnant women with varying degrees of obesity were examined and treated. It turned out that the course of intravenous drip administration of ozonated saline solution leads to the normalization of a number of important indicators of homeostasis including stimulation of the antioxidant system and reduction of peroxide stress. The reduction in the frequency of miscarriage, preeclampsia, premature birth, and bleeding during childbirth and the postpartum period is achieved. It`s possible to recommend the inclusion of ozone therapy in the preventive treatment of pregnant women with exogenous constitutional obesity.

The emergence of dramatic urinary tract infections (UTIs) caused by the members of the Enterobacteriales is an important public health problem in the community as well as in Tunisian hospitals. This study aims to investigate the prevalence of extended-spectrum β-lactamase (ESBL) and carbapenemase-producing uropathogenic isolates of Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae). Based on decreased susceptibility to β-lactams antibiotics and analyzed for the presence of ESBL and carbapenemase genes by Real Time- polymerase chain reaction (RT-PCR), 56 uropathogenic isolates of E. coli (n = 36) and K. pneumoniae (n = 20) were confirmed positive for ESBLs. The CTX-M-type β-lactamases were mostly detected in E. coli isolates (21 strains, 58.33% [95% CI 38.09% - 72.06%]) followed by blaSHV-like (18 strains, 50% [95% CI 32.92% - 67.07%]), blaTEM-like and blaCMY-2-like simultaneously (15 strains, 41.67% [95% CI 25.51% - 59.24%]). Furthermore, the RT-PCR system on the K. pneumoniae strains demonstrated that blaSHV-12-like was the most predominant (16 strains, 80% [95% CI 56.33% - 94.26%]) followed by blaTEM-like (14 strains, 70% [95% CI 45.72% - 88.10%]), blaCTX-M belonging to groups 9 and 1 (11 strains, 55% [95% CI 31.52% - 76.94%]) and finally blaCMY-2-like (10 strains, 50% [95% CI 27.19% - 72.80%]). In addition, E. coli and K. pneumoniae strains harbored a carbapenemase gene blaOXA-48-like with 22.2% [95% CI 10.11% - 39.15%]; 20% [95% CI 12.83% - 43.66%], respectively.Our results confirm the need to monitor the resistance to extended-spectrum β-lactams and to carbapenems among enterobacteria in Tunisia.

It is planned to carry out a comprehensive experimental and theoretical study on the high temperature of low calorific gas combustion with oxygen-deficient oxidizers. The experimental research will be performed using the experimental facility with a combustion chamber. The oxygen concentration in combustion oxidizers will be varied from 21% by volume (normal) air to 2%. The test combustion chamber will be fed with propane or methane as the reference fuel, then with low calorific fuels as test gases obtained by mixing various combustible components, e.g. H2, CH4, CO, and neutral gases, e.g. N2, CO2. Gaseous fuels prepared in this way will be burned in the atmosphere of a deficient oxidizer with a temperature changing from 800 °C to 1100 °C. Oxidizers will be heated up to a certain temperature using two methods: by flue gas heat exchanger and kanthal rod electric preheater. Different burner geometry will be used. The burner will be equipped with annular swirl vanes for co-axial or under different angles, fuel, and oxidizers flow to have a high swirl number achieved by flow aerodynamics and mixing. Experimental data will be verified with numerical simulations with the use of ANSYS CFD Fluent code.

True hermaphroditism (TH) is a cause of intersexuality in which both ovarian and testicular tissue is present in the same individual [1]. The gonadal distribution in cases of true hermaphroditism varies from [2]

Parkinson’s disease is a progressive and debilitating neurodegenerative disorder affecting millions of people worldwide. The disease is characterized by motor symptoms such as tremors, rigidity and postural instability, as well as non-motor symptoms such as depression and cognitive impairment. While there is no cure for Parkinson’s disease, there are various treatments available to manage symptoms and improve quality of life for patients.This case study examines a 65-year-old retired accountant, Mr. John Smith, who was diagnosed with Parkinson’s disease five years ago. Mr. Smith has been treated with a combination of medications, including levodopa and carbidopa and physical therapy to manage his symptoms. However, his symptoms have not significantly improved.This literature review explores the current research on Parkinson’s disease, including its pathophysiology, diagnosis and treatment. Parkinson’s disease is caused by the degeneration of dopamine-producing neurons in the brain, leading to a depletion of dopamine and the accumulation of alpha-synuclein protein, oxidative stress and inflammation. Diagnosis is based on clinical symptoms, neurological examination and response to dopaminergic therapy. Treatment focuses on managing symptoms, with medications and non-pharmacological interventions such as exercise and physical therapy. Deep brain stimulation is a surgical treatment option that has been shown to be effective in managing motor symptoms.While there is currently no cure for Parkinson’s disease, ongoing research into its pathophysiology and treatment holds promise for improving outcomes for patients. This case study highlights the importance of early diagnosis and personalized treatment plans for patients with Parkinson’s disease.

Today, there are said to be some 590 million people of all ages around the world, who are suffering from a range of swallowing problems – probably about 4 million in the UK. Either living at home or as residents in some 20,000 Care Homes, with perhaps another 25,000 as patients in hospitals every day.Professor David Smithard, of the Lewisham and Greenwich NHS Trust, has been leading a national campaign for some years to raise general awareness of Dysphagia and to improve the treatment of patients with varying conditions. He and his team at the Queen Elizabeth Hospital have now completed a detailed Review of the use of carbonated water (CW) in the treatment of Dysphagia, which has just been published and can be accessed here: https://www.mdpi.com/2308-3417/8/1/6The Review concludes that further evidence-based research is essential before CW can be adopted as standard in clinical practice – but that although the amount of evidence is small, there is a suggestion that swallows are safer and that secretion management improves, and consequently until further studies are undertaken, Carbonated Water should be limited to individual patient use.My experience as a Dysphagia sufferer is that the use of CW has resulted in life-changing benefits, and this paper is devoted to describing how CW worked for me, and what the practical requirements are, so that many others may be able to benefit as I have done. The paper has three sections: My Personal Experience, Practical Considerations, and Conclusions.

In the past, natural pigments derived from plant-biomass wastes had been widely used for coloring purposes (e.g. fabrics/batik), before finally getting pushed aside by the imported synthetic/inorganic pigments. Thorough attempts to revive the use of such natural pigments then deserve carrying out. Relevantly, conducting storage of liquid/wet or dry natural coloring pigments, extracted from wood wastes; and use of fixatives for batik fabrics intended to impart fabric-color variations. Wood wastes (i.e. leaves and barks) were obtained from nine plant species (Acacia mangium Willd, Avicenia marina L, Caesalpinia sappan L, Ceriop tagal Perr. CB. Rob, Pelthophorum ferruginum Benth, Rhyzophora mucronata Lamk, Tectona grandis Linn.f., Terminalia catappa L and Xylocarpus granatum KD Koenig.), prevalently growing on plain/lowland areas; and their wood portions commonly utilized by wood industries, which generate similar wastes enormously. The pigments in liquid/wet and then in dry forms were produced from those wastes. The production process of pigments adopted traditions by local batik crafters in Bogor. Variations occurring in fabric colors could be due to fixatives, i.e. lime (CaCO3), ferrous sulphate/tunjung (FeSO4); and various wastes. Six-month storage insignificantly changed the coloring qualities of natural coloring pigments applied to fabrics, compared to those of corresponding initially produced pigments. Leaf wastes always contained green-colored compounds, while bark wastes appeared aptly brownish in color. Color performances of bark extracts at fabrics with ferro-sulfat fixative brought about strong grey colors, and with lime fixative produced brown colors. Coloring of fabrics using leaf waste extracts with ferro-sulfat fixative aptly exhibited greenish grey; while with lime fixative became reddish brown. Testing results on the leaching resistance of pigment-colored and fixative-treated fabrics against rubbing and exposure to sunlight revealed a very good category (4-5), but against detergent, washing was very low (2-3).

The review article examines the production of molecular hydrogen from the decomposition of water by various irradiation methods. The article shows different types of radiation: UV radiation, visible radiation, gamma radiation, X-ray radiation and neutron radiation. Electrons generated by radiation inside a nanoparticle of radius R suspense in fluid water are diffused with equal probability in all directions inside the particle and gradually lose their kinetic energy as a result of elastic and inelastic collisions. Some of these electrons are transported to the nanoparticle surface during the physical and physicochemical stages of the process and emitted into the water. It is extremely important for the formation of nanostructured materials after exposure to ordered nanostructure from the new phase with a period of a few nanometers, promoting the preservation of the properties of materials under high irradiation.
