This article presents the development and characterization of environmentally friendly composites comprising polypropylene (PP) reinforced with Bahia Beige (BB) marble waste. The composites were prepared using different PP/BB weight ratios and analyzed for their chemical, physical, mechanical, microstructural, and thermal properties. X-ray fluorescence (XRF) analysis revealed the composition of BB, which exhibited a significant concentration of CaO, indicating the presence of calcite and other oxides. X-ray diffrac [...]

Transcutaneous auricular vagal nerve stimulation (taVNS) is a non-invasive method that regulates the autonomic nervous system via electrical stimulation of the auricular branch of the vagus nerve. Recent literature demonstrates that taVNS can decrease systemic inflammation, attenuate emotional disorders, modulate autonomic functions, and facilitate neural plasticity. This review examines the neurophysiological mechanisms of taVNS, including stimulation paradigms (short- and intensive, prolonged), and clinical findi [...]

Background: Hematopoietic cell transplant (HCT) patients are a high-risk population for poor nutrition and decreased survival. There is little data on how nutrition in pediatric HCT patients affects need for critical care interventions and outcomes. Methods: We hypothesized that patients who did not meet goal nutrition by 72 hours post-admission to the pediatric intensive care unit (PICU) had increased in-hospital mortality and increased need for critical care interventions. We performed a retrospective cohort stud [...]

Drought and phosphorus (P) deficiency stress are two significant natural abiotic stresses restricting rice growth and yield worldwide. Developing rice varieties tolerant to drought and low P stress is crucial for sustainable agricultural production. To address these issues, two separate experiments were conducted using selected advanced rice breeding lines to study the impact of drought and low P stress on yield-attributing traits. The first experiment evaluated the drought stress tolerance of five advanced lines ( [...]

There are several definitions of sympathy, empathy, and compassion on the internet. I have chosen the above definitions to emphasize their salient differences, for the following reason: In medical school, in the early 1960s, we were taught not to sympathize with patients, but to empathize: By empathizing, one can retain some professional objectivity toward the patient, in order to be of some help. To sympathize, on the other hand, was to immerse oneself in the patient’s suffering and lose one’s professional per [...]

Chronic constipation and irritable bowel syndrome (IBS) are two of the most common functional gastrointestinal disorders, both of which negatively affect the quality of life of the patients. Since people may have co-existing symptoms of multiple disorders, chronic constipation and IBS with predominant constipation cannot be clearly distinguished. In this cross-sectional study, data were obtained from self-administered questionnaires to assess the prevalence of chronic constipation and IBS, and their overlap, among [...]

The authors attempted to operationalize the clinical work of strategic theorist and expert family therapist, Scott Browning. Strategic therapy takes the position that a client is stuck, not necessarily sick. This focus encourages the clinician to create alternative perspectives such that a client learns to consider a problem from a new lens. Milton Erickson, a progenitor of strategic thinking, used hypnosis and paradox to nudge clients toward a useful alternative perspective [1]. The present article examined three [...]

2-Phenyl-4-arylmethylidene-5-oxazolinones were synthesized in very high yield by subjecting a mixture of an aryl aldehyde/heterocyclic aldehyde/cinnamaldehyde and hippuric acid in anhydrous acetic anhydride and catalytic Zn(OCOCH3)2·2H2O to ultrasonication at 35 KHz for 4 to 8 min. This method has many advantages: use of a green catalyst; yields are high, involves easy workup procedure, is energy efficient and economically feasible.

Covid-19 pandemic has been infecting a substantial portion of the world population, thereby revealing quality deficits in health care in the majority of the countries around the globe. Severe illness and mortality from Covid-19 infection are present predominantly in minorities; especially they are more frequent in geriatric patients. Unfortunately, our knowledge is limited about what accounts for the variability in immune response from one person to another. This question is far from being merely academic, and find [...]
