Background: Effective workflow management in a diagnostic pathology laboratory is critical to achieve rapid turnover while maintaining high quality. Fluorescence in situ hybridization analysis (FISH) is the preferred technique for detecting single chromosomal aberrations in diagnostic surgical pathology.
Material And Methods: FISH analysis applying a rapid hybridization protocol and using an automated whole-slide fluorescence scanning device (3DHISTECH, Sysmex, Switzerland) were implemented in our workflow. By analyzing 42 diagnostic cases, effects of two different scanning profiles on scanning time, and device memory usage were investigated. Manual signal counting (CaseViewer) and software based signal counting (FISHQuant) were compared.
Results: The two scanning profiles, both including a Z-stack function, differed in their exposure time and digital gain. The "low profile" setting (LP) resulted in a significantly shorter scanning time and lower storage volume compared to the "high profile" (HP) setting, making the LP ideal for routine applications. Both signal counting methods (manual versus software based) provided similar cut-offs on a test-cohort of 13 samples.
Conclusion: Scanning FISH slides provides good picture quality, reduces the analysis time and allows easy picture archiving and facilitates remote diagnostics, allowing an effective workflow.

Background: Mecapegfilgrastim, a long-acting granulocyte colony-stimulating factor, is approved in China for neutropenia prevention. However, data on its safety and efficacy in patients with head and neck cancer remain limited. This study aimed to evaluate the safety and efficacy of mecapegfilgrastim in preventing neutropenia among these patients undergoing chemotherapy, particularly those receiving chemoradiotherapy or chemoimmunotherapy.

Background: Speckle-type POZ protein (SPOP), FAS-associated protein with death domain (FADD), and nuclear transcription factor-κB (NF-κB) have been shown to be associated with the development of prostate cancer (PCa). FADD has been shown to activate the NF-κB pathway to promote tumorigenesis, while SPOP has been shown to enhance the breakdown of FADD and inhibit the function of the NF-κB signaling pathway in non-small cell lung cancer. The existence of this mechanism has not yet been confirmed in PCa.

Intervertebral disc degeneration (IVDD) is a common contributor for low back pain, which is featured by loss of extracellular matrix and nucleus pulposus cells (NPCs). Hence, our current study is undertaken to explore the potential mechanism of NPC apoptosis during IVDD. Transcription factor Dp-1 (TFDP1) expression in degenerative and non-degenerative intervertebral disc tissues was analyzed by bioinformatics.

By determining the time-variant Doppler shift of the reflected probe signal, this system successfully reconstructs various audio signals, including pure sinusoidal, multi-tonal, and musical signals, up to 200 Hz, limited by the laser frequency modulation rate and the Nyquist sampling theorem. Additionally, we employ scanning galvo mirrors to perform 3D measurements and map audio signals from different regions in the scanned field of view.

Cytoskeletal remodeling and mitochondrial bioenergetics play important roles in thrombocytopoiesis and platelet function. Recently, α-actinin-1 mutations have been reported in patients with congenital macrothrombocytopenia. However, the role and underlying mechanism of α-actinin-1 in thrombocytopoiesis and platelet function remain elusive.
