A Deep Learning Model for Estimating the Quality of Bimetallic Tracks Obtained by Laser Powder-Directed Energy Deposition.

During the fabrication of Inconel 718-AISI 316L bimetallic components via laser powder-directed energy deposition, understanding the relationships between processes, microstructures, and material properties is crucial to obtaining high-quality parts. Physical-chemical properties, cooling rates, and thermal expansion coefficients of each material may affect the microstructure of parts, generating segregations and cracks. This paper analyzes how the process parameters affect the dimensions, chemical composition, and microhardness of bimetallic tracks.

Effects of Switching FSH Preparations on Sperm Parameters and Pregnancy: A Prospective Controlled Study.

To study the effect of switching to a follicle-stimulating hormone (FSH) preparation other than that to which infertile male patients have not had an effective response. Seventy-four normogonadotropinemic, non-obstructive, oligozoospermic patients who were poor responders to the administration of highly purified FSH (hpFSH) (Group 1 (n = 22) and Group 3 (n = 15)) or to recombinant human FSH (rhFSH) (Group 2 (n = 22) and Group 4 (n = 15)) were selected for this prospective study. After 3 months of washout from treatment with the first FSH preparation of choice, rhFSH was administered to patients in Groups 1 and 4 and hpFSH to those in Groups 2 and 3.

Prostate Cancer: Emerging Modifiable Risk Factors and Therapeutic Strategies in the Management of Advanced Cancer.

Prostate cancer (PCa) is the third highest cause of cancer death in men. PCa is a very heterogeneous tumor form in terms of grade, phenotypes, and genetics, often accompanied by complex networks. PCa is characterized by slow growth that does not compromise the patient's quality of life, unlike more aggressive forms showing rapid growth and progression.

Can nutraceuticals counteract the detrimental effects of the environment on male fertility? A parallel systematic review and expert opinion.

Introduction: Male fertility relies on a complex physiology that may be negatively influenced by lifestyle, diet, and environment. The beneficial effect of nutraceuticals on male fertility is a debated claim. The aim of this study was to assess if the positive effect of nutraceuticals can counteract the negative effects of the environment on male fertility.
