Background And Objective: Male fertility assessment through sperm morphology analysis remains a critical component of reproductive health evaluation, as abnormal sperm morphology is strongly correlated with reduced fertility rates and poor assisted reproductive technology outcomes. Traditional manual analysis performed by embryologists is time-intensive, subjective, and prone to significant inter-observer variability, with studies reporting up to 40% disagreement between expert evaluators. This research presents a novel deep learning framework combining Convolutional Block Attention Module (CBAM) with ResNet50 architecture and advanced deep feature engineering (DFE) techniques for automated, objective sperm morphology classification.

Neuronal heterogeneity, characterized by a multitude of spiking neuronal patterns, is a widespread phenomenon throughout the nervous system. In particular, the brain exhibits strong variability among inhibitory neurons. Despite the huge neuronal heterogeneity across brain regions, which in principle could decrease synchronization due to differences in intrinsic neuronal properties, cortical areas coherently oscillate during various cognitive tasks.

Introduction: Interstitial lung disease is a major complication in patients with common variable immunodeficiency. There are some publications that try to shed light on the pathophysiology of this non-infectious complication, most of them highlight the role of follicular T cells and CD21 B cells. Moreover, there are no guidelines based on randomized controlled studies on the treatment of patients with interstitial lung disease and the published case series or small uncontrolled studies describe a wide range of response rates to treatment.

Mast cell tumors (MCTs) are the most common skin neoplasms in dogs and exhibit highly variable biological behavior. Metastasis primarily affects the lymph nodes, though less frequently, MCTs can infiltrate the spleen, liver, peripheral blood, and bone marrow. Flow cytometry of fine needle aspirate samples represents a non-invasive diagnostic procedure that has shown promise for detecting and quantifying mast cells in primary tumors and lymph nodes.

Introduction: In Pap test reports, sample quality is assessed based on the presence of squamous-columnar junction (SCJ) cells and atypia.
Objective: To assess the quality of Pap test samples by analyzing the frequency of SCJ cells in Pap test results and examining their association with sociodemographic, clinical, and professional-related variables.
Materials And Methods: A cross-sectional study was conducted using 1.
