Objectives: This study aims to introduce and differentiate between traditional craze lines and a newly identified type of line in enamel, termed an “internal craze line.” This novel classification enhances diagnostic precision and carries significant clinical implications for treatment strategies. The goal is to provide a clear description of these two types of lines, discuss their unique clinical implications, and highlight their differing appearances and staining characteristics, contributing to improved understanding and management of enamel anomalies.Method and materials: Four extracted teeth exhibiting visible and internal craze lines were selected and examined using a stereo microscope to observe the structural characteristics of the lines. Cross-sections of the coronal parts of the teeth were prepared to document the differences between traditional craze lines (extending from the dentin-enamel junction [DEJ] to the enamel surface) and internal craze lines (originating at the DEJ but terminating midway through the enamel). Additionally, intraoral observations were conducted under high magnification to identify the visual differences between the two types of lines, noting that traditional craze lines can be stained while internal craze lines cannot.Results: Microscopic examination revealed two distinct types of lines: traditional craze lines extending from the DEJ to the enamel surface and internal craze lines terminating within the enamel. Intraoral observations confirmed that these lines could be distinguished under high magnification. Traditional craze lines appear as continuous lines reaching the enamel surface and can be stained, whereas internal craze lines are shorter, do not extend to the surface, and cannot be stained.Conclusion: The identification of internal craze lines presents significant clinical implications. Differentiating between traditional and internal craze lines can enhance diagnostic accuracy and inform treatment decisions. Recognizing internal craze lines might indicate different etiologies or risk profiles compared to traditional craze lines, influencing preventive and therapeutic strategies in dental practice. Further research is needed to explore the prevalence, causes, and long-term impacts of internal craze lines.

Introduction: In many developing countries, particularly in Africa, the use of renal biopsy (RB) in clinical nephrology is severely lacking. The objectives were to describe the anatomoclinical and etiological profile of these biopsied nephropathies, as well as the factors associated with the etiology of the nephropathies.Patients and method: This was a retrospective descriptive and analytical study from 1 April 2020 to 30 October 2022. The patients were selected from the renal biopsy register of the nephrology department of the Thiès Regional Hospital. Sociodemographic, clinical, biological, and histological parameters were studied.Results: 75 renal biopsies were included. The mean age was 33.3 ± 14.8 years, with a male predominance (65.3%). The main indications were nephrotic syndrome in 50.67% of cases. RB was adequate in 82.7%, inadequate in 13.3%, and borderline in 4%. Glomerular nephropathies predominated, with focal segmental glomerulosclerosis (FSGS) in 34.7%, membranous nephropathy (MN) in 17.3%, minimal change disease (MCD) in 10.67%, extracapillary glomerulonephritis (ECGN) in 5.3% and lupus nephritis (LN) in 3.9%. Thrombotic microangiopathy (TMA) was found in 9.3%. Chronic tubulointerstitial nephropathy (CTIN) accounted for 5.3% of all RB and acute tubular necrosis (ATN) for 4%. The etiologies were primary in 48%, secondary in 28%, and undetermined in 24%. In the bivariate analysis, the etiology was correlated with the mean SBP (p = 0.023), the mean level of hemoglobin (p = 0.028), the levels of GFR (p = 0.017), and the type of kidney disease (p = 0.000).Conclusion: Glomerular nephropathy was more frequent and FSGS was the most common histological lesion found. Primary causes predominated. Associated factors were identified to improve patient management.

The SARS-CoV-2 pandemic, which began in late 2019, initially manifested with acute respiratory symptoms, including bilateral pneumonia, and later emerged as a systemic disease. This brief report assesses changes in the clinical profiles of psychiatric outpatients before, during, and after the pandemic’s most severe periods, focusing on mood, anxiety, and cognitive symptoms. Data from a private psychiatric facility in Rome reveal that both pandemic-related stressors and SARS-CoV-2 infection itself may contribute to enduring affective and cognitive symptoms in both older and younger adult subgroups. Notably, during the pandemic, older patients showed elevated psychopathology scores (BPRS-24) compared to younger individuals. In the post-pandemic period, younger adults exhibited increased positive symptoms on the PANSS Positive subscale, suggesting a gradual worsening in symptoms post-pandemic ( = 0.47). Cognitive assessments (MMSE and PM38) further highlighted fluctuating performance over time, with older adults showing two distinct declines during the pandemic and in 2024. This work underscores the importance of sustained mental health interventions to address the pandemic’s psychosocial and neuroinflammatory legacy. This perspective also considers new data on the CNS effects of “toxin-like peptides” synthesized by microbiome bacteria.

This study evaluates the effects of two months of regular snoezelen therapy on anger-hostility (AH), assessing both psychological and physiological indicators before and after the intervention. Using the Profile of Mood States (POMS-2), the research measured changes in anger-hostility levels and stress responses, comparing pre- and post-intervention data. At baseline, participants exhibited relatively high levels of anger-hostility, with psychological scores averaging 40.14 (± 2.46) and physiological scores averaging 42.25 (± 2.71), indicating significant irritability, aggression, and elevated stress responses. After two months of multisensory stimulation in a snoezelen room, participants’ psychological scores decreased to 37.40 (± 2.26) and physiological scores to 39.50 (± 2.01), suggesting improvements in mood and physiological stress. The statistical analysis yielded a p - value of 0.047, indicating that the reductions were significant. These findings suggest that snoezelen therapy can be effective in reducing anger-hostility and associated physiological stress, offering a promising intervention for emotional regulation and stress management.

Dyspepsia refers to acute, chronic, or recurrent pain or discomfort centered in the upper abdomen. An international committee of clinical investigators (Rome III Committee) has defined Dyspepsia as Epigastric pain or Burning, early satiety, or postprandial fullness Dyspepsia occurs in 15 % of the Adult population and accounts for 3% of general medical office visits. The descriptive study was carried out in Eastern Afghanistan, Afghan Momand Medical Complex & Research Center, Department of Gastroenterology, during the years 2023-2024. To know the Clinico-Endoscopy of Dyspepsia, for patients who present with investigated Dyspepsia to Gastroenterological OPD & IPD. The study result showed, there were a total of patients 467, and of these patients 230 were Male and 237 were Female.

Bifurcation analysis and Multiobjective Nonlinear Model Predictive Control (MNLMPC) calculations were performed on a model of circadian oscillations of the Period (PER) and Timeless (TIM) proteins in Drosophila. The MATLAB program MATCONT was used to perform the bifurcation analysis. The optimization language PYOMO was used along with the state-of-the-art global optimization solvers IPOPT and BARON for the MNLMPC calculations. The bifurcation analysis revealed oscillation causing Hopf bifurcations while the MNLMPC calculations revealed the existence of spikes in the control profiles. Both Hopf bifurcation points and the control profile spikes were eliminated using an activation factor involving the hyperbolic tangent function.
