Purpose: To detect possible morphologic changes in the urethra in an attempt to clarify the effects of thermotherapy (TUMT).

Material And Methods: Eighteen patients with symptomatic disturbance in micturition and a prostatic volume of 14-133 cm3 underwent voiding cystourethrogram and retrograde urethrogram before and 6 and 12 months after treatment. TUMT treatment was carried out with a Prostatron unit.

Results: No correlation was found between subjective improvement in symptoms and morphologic changes of the urethra. There were more responders among patients who received a high microwave effect.

Conclusion: We conclude that there is no evidence to support the view that TUMT leads to significant necrosis in the prostrate with loss of tissue and retraction. Our results support the view that TUMT causes denervation of the prostate.

Background: During mammalian spermatogenesis, the cytoskeleton system plays a significant role in morphological changes. Male infertility such as non-obstructive azoospermia (NOA) might be explained by studies of the cytoskeletal system during spermatogenesis.

Methods: The cytoskeleton, scaffold, and actin-binding genes were analyzed by microarray and bioinformatics (771 spermatogenic cellsgenes and 774 Sertoli cell genes).

Purpose: To utilize optical coherence tomography (OCT) and SS-OCT angiography (SS-OCTA) for quantifying morphological changes seen in eyes with recalcitrant neovascular age-related macular degeneration (nAMD) transitioned to intravitreal faricimab injections during the manufacturer's recommended induction phase of treatment.

Methods: Fifty-four treatment-recalcitrant patients (60 eyes) were recruited. OCT and SS-OCTA images were obtained at 0 and 3 months.

The expansion of drone-based aerial imagery has facilitated an increase in data obtained from free-ranging marine mammal populations, in particular cetacean species. This non-invasive approach allows for body condition assessments, including nutritional and reproductive health. Yet, existing methods of image analysis are time-consuming and lack the granularity to determine early-stage pregnancies and miscarriage rates.

Understanding the global transcriptomic and metabolic changes during mulberry growth and development is essential for the enhancing fruit quality and optimizing breeding strategies. By integrating phenotypic, metabolomic, and transcriptomic data across 18 developmental and ripening stages of Da10 mulberry fruit, a global map of gene expression and metabolic changes was generated. Analysis revealed a gradual progression of morphological, metabolic, and transcriptional changes throughout the development and ripening phases.
