Random call has been proposed as an inclusive and equitable practice that engages students in learning. However, this inclusion may come with a cost. In some contexts, students experience anxiety and distress when being called on.

Undergraduate research experiences have been widely demonstrated as a beneficial and essential component of the college experience. However, many community colleges face barriers and lack of support in implementing such research programs, which means a significant number of community college students miss out on these impactful experiences. Course-based undergraduate research experiences (CUREs) represent a feasible way to increase access to research experiences within community colleges.

Prosthetic joint infection (PJI) is a rare but devastating complication of joint arthroplasty. Biofilm formation around the prosthesis confers tolerance to antibiotics so that treatment is challenging. Most animal models of PJI use planktonic bacteria to establish the infection which fails to reproduce the pathology of chronic infection.

The purpose of the study is to describe the experience of a multidisciplinary team in a tertiary hospital regarding the management of Infantile Hemangiomas (IH). The method employed is a retrospective analysis of patients with IH followed in a tertiary pediatric hospital between January 2010 and May 2022. A total of 393 IH were diagnosed (56.

The introduction of magnetic resonance (MR) linear accelerators (MR-Linac) marks the beginning of a new era in radiotherapy. MR-Linac systems are currently being operated by teams of radiation therapists (RTs), radiation oncology medical physicists (ROMPs) and radiation oncologists (ROs) due to the diverse and complex tasks required to deliver treatment. This is resource-intensive and logistically challenging.

The introduction of magnetic resonance (MR) linear accelerators (MR-Linacs) into radiotherapy departments has increased in recent years owing to its unique advantages including the ability to deliver online adaptive radiotherapy. However, most radiation oncology professionals are not accustomed to working with MR technology. The integration of an MR-Linac into routine practice requires many considerations including MR safety, MR image acquisition and optimisation, image interpretation and adaptive radiotherapy strategies.

Introduction: The magnetic resonance linear accelerator (MRL) offers improved soft tissue visualization to guide daily adaptive radiotherapy treatment. This manuscript aims to report initial experience using a 1.5 T MRL in the first 6 months of operation, including training, workflows, timings and dosimetric accuracy.

Purpose: Reviewing surgical procedures using fasciocutaneous and myocutaneous flaps for inguinal reconstruction after lymphadenectomy in metastatic penile cancer.

Material And Methods: We reviewed the current literature of the Pubmed database according to PRISMA guidelines. The search terms used were "advanced penile cancer", "groin reconstruction", and "inguinal reconstruction", both alone and in combination.

Paratuberculosis or Johne's disease, caused by Mycobacterium avium subsp. paratuberculosis (Map), is a chronic granulomatous enteritis affecting both domestic and wild ruminants. The present work is part of a wider set of studies designed to assess the prevalence of paratuberculosis in free ranging red deer (Cervus elaphus).

We describe the case of a teenager with a structurally normal heart that presented with and cardiac arrest. He had a history of epilepsy in childhood, mild cognitive impairment and cognitive visual dysfunction. The baseline electrocardiogram had prominent J waves and a marked early repolarization pattern in all the leads, with normal QT interval.

Anomalous pulmonary venous connection is an uncommon congenital anomaly in which all (total form) or some (partial form) pulmonary veins drain into a systemic vein or into the right atrium rather than into the left atrium. The authors present one case of total anomalous pulmonary venous connection and two cases of partial anomalous pulmonary venous connection, one of supracardiac drainage into the brachiocephalic vein, and the other of infracardiac anomalous venous drainage (scimitar syndrome). Through the presentation of these cases, this article aims to review the main pulmonary venous developmental defects, highlighting the role of imaging techniques in the assessment of these anomalies.

Noonan syndrome is a relatively common and heterogeneous genetic disorder, associated with congenital heart defect in about 50% of the cases. If the defect is not severe, life expectancy is normal. We report a case of Noonan syndrome in a preterm infant with hypertrophic cardiomyopathy and lethal outcome associated to acute respiratory distress syndrome caused by Adenovirus pneumonia.

Germ cells are maintained in a pristine non-aging state as they proliferate over generations. Here, we show that a novel function of the Caenorhabditis elegans RNA interference proteins RNAi spreading defective (RSD)-2 and RSD-6 is to promote germ cell immortality at high temperature. rsd mutants cultured at high temperatures became progressively sterile and displayed loss of small interfering RNAs (siRNAs) that target spermatogenesis genes, simple repeats, and transposons.

Homeostasis of postmitotic and proliferating cells is maintained by pathways that repress stress. We found that the Caenorhabditis elegans histone 3 lysine 4 (H3K4) demethylases RBR-2 and SPR-5 promoted postmitotic longevity of stress-resistant daf-2 adults, altered pools of methylated H3K4, and promoted silencing of some daf-2 target genes. In addition, RBR-2 and SPR-5 were required for germ cell immortality at a high temperature.

The aim of this study was to compare two diagnostic methods for the detection of Mycobacterium avium complex (MAC) infection in lymph nodes with granulomatous lymphadenitis from slaughtered domestic pigs. Fifty affected lymph nodes were collected from 50 pigs and examined microscopically and by polymerase chain reaction (PCR). Microscopically, granulomatous lesions were observed in 92% of the samples, consisting mostly of central necrosis (78%) with dystrophic calcification (46%) and associated with inflammatory infiltration by epithelioid giant cells, lymphocytes, neutrophils (92%), eosinophils (60%) and Langhans-type cells (70%).

Unlabelled: Kawasaki disease (KD) is an acute, self-limiting, idiopathic form of vasculitis. The preventive effect of early therapy on coronary artery aneurysms, the hallmark of the disease, is well established. The spectrum of complication includes not only cardiac involvement but also central nervous system lesions.

Pulmonary hypertension (PH) was until recently an obscure pathology which frequently went unidentified as it lacked a precise diagnostic strategy. Recent years have seen advances in the knowledge of the pathogenesis and mechanisms of vascular lesion of PH. This has led to the scientific community's growing interest in this area, an interest manifested in appreciable progress in the pathology's clinical characterisation, diagnostic strategies and the development of effective drugs.

Cell adhesion to the extracellular matrix (ECM) via integrin adhesion receptors initiates signaling cascades leading to changes in cell behavior. While integrin clustering is necessary to initiate cell attachment to the matrix, additional membrane components are necessary to mediate the transmembrane signals and the cell adhesion response that alter downstream cell behavior. Many of these signaling components reside in glycosphingolipid-rich and cholesterol-rich membrane domains such as Tetraspanin Enriched Microdomains (TEMs)/Glycosynapse 3 and Detergent-Resistant Microdomains (DRMs), also known as lipid rafts.
