The present study deals with the development of scaffolds based on gelatin (G) and/or chitosan (CH) through modifications in the central processing method. This process consists of the fabrication of a hydrogel which is, then submitted to a freeze-drying stage. To compare the effects of the different modifications, the mechanical properties of the various systems were characterized, employing both dynamic compressive strain and frequency sweep tests. In addition, their porosity as well as the structure and fiber di [...]

The TiO2/MCM-41 nanomaterials were synthesized by impregnation with an excess solvent with different percentages of titanium dioxide. They were used for catalytic degradation of Benzene Toluene Ethylbenzene and Xylenes (BTEX) in the presence of hydrogen peroxide in aqueous media. The obtained materials were characterized by X-ray Diffraction, nitrogen adsorption-desorption using the BET method and Fourier Transform Infrared Spectroscopy. The nanostructured phase of the hexagonal ordered materials was obtained even [...]

This study aims to assess the Trophectoderm (TE) biopsy practice in Jordan in terms of the following effectiveness parameters: timing of zona breaching, risk of inner cell mass herniation if zona breaching was done on day 3, timing of TE sampling, method of biopsy (pulling or flicking), number of laser pulses, assessment of embryo survival after biopsy, and degeneration rate. An online cross-sectional survey was conducted in November 2022. The collected data presented the perception of embryologists (>10 years e [...]

Peripheral inflammation plays an important role in the pathophysiology of Alzheimer’s disease (AD) and dysregulations in circulating levels of different inflammatory mediators are detectable as early as the mild cognitive impairment (MCI) stage towards AD. Depressive symptoms, another risk factor of AD, are often found in individuals with MCI and associated with heightened levels of peripheral inflammatory mediators. Diminution in depressive symptoms and alterations of peripheral inflammation profiles have been obs [...]

Background: Streptomyces avermitilis is an actinomycete that produces avermectins. The complete genome sequence of S. avermitilis K139 was determined in 2003. In our previous study, we revealed that S. avermitilis NBRC 14893T harbors two extra secondary metabolite-biosynthetic gene clusters (smBGCs), com and ptx, which are not present in strain K139. Methods: Whole-genome sequencing for S. avermitilis NBRC 14893T and ATCC 31267T was carried out by the SMRT DNA sequencing technology to determine the genomic loci enc [...]

More than 60% of adult women in the United States have urinary incontinence (UI), with the prevalence increasing to over 80% in women over age 65. Despite its high prevalence, most patients do not seek care and few clinicians screen for UI. The Medicare Health Outcomes Survey queries patients about satisfaction with their provider’s discussion and management of UI, but formal recommendations about screening, diagnosis, and treatment are lacking. This review presents a practical algorithm for primary care providers [...]

Increased body fat mass can lead to lifestyle diseases such as hypertension, diabetes, and hyperlipidemia. Metabolic syndrome is a cluster of conditions that increases the onset of multiple diseases, such as cardiovascular diseases, stroke, and type 2 diabetes, which are closely related to lipid metabolism; therefore, new prevention approaches and treatments are needed. Our study investigated the effects and mechanism of YNCRG on anti-obesity in metabolic syndrome model SHR.Cg-Leprcp/NDmcr (SHRCP) rats. Eight-week- [...]

Background: The participation of mental health professionals in multidisciplinary care teams for heart transplantation has become an international standard practice. The contribution of these professionals in this setting, which involves assessment and interventions, has not been the subject of systematic study. Methods: This paper explores how psychotherapists contribute to multidisciplinary decision making and care in transplant teams before, during, and after transplantation. To illustrate, it uses the case of a [...]

Catatonia and malignant catatonia may result in devastating and life-threatening complications like pulmonary embolisms, pneumonia, deep venous thrombosis, rhabdomyolysis, and even death. There have been documented cases implicating alcohol withdrawal as a significant culprit in catatonia. Here, we provide a unique case report of a patient with a complicated medical course, who subsequently developed malignant catatonia secondary to severe alcohol withdrawal, and was successfully treated using both first line treat [...]

Research has shown that compassion – whether to others, from others or to oneself – can be associated with improved well-being and mental health. Most measures to date focus on one of these flows of compassion, with only one recently published scale tracking all three. The primary aim of the current study was to investigate the psychometric properties of The Compassionate Engagement and Action Scales (CEAS) in a UK sample. The secondary aims were to investigate the level of compassion, as measured by th [...]
