Varicocele repair is mainly indicated in young adult patients with clinical palpable varicocele and abnormal semen parameters. Varicocele treatment is associated with a significant improvement in sperm concentration, motility, morphology, and pregnancy rate. Antegrade scrotal sclerotherapy （ASS） represented one of the main alternatives to the traditional inguinal or suprainguinal surgical ligation. This article reviews the use of ASS for varicocele treatment. We provide a brief overview of the history of the procedure and present our methods used in ASS. In addition, we review complication and success of ASS, including our own retrospective data of treating 674 patients over the last 17 years. Herein, we analyzed step by step the ASS technique and described our results with an original modified technique with a long follow-up. Between December 1997 and December 2014, we performed 674 ASS. Mean operative time was 14 min （range 9 to 50 min）. No significant intraoperative complications were reported. Within 90 days from the procedure, postoperative complications were recorded in overall 49 （7.2%） patients. No major complications were recorded. A persistent/recurrent varicocele was detected in 40 （5.9%） cases. In 32/40 （80%） cases, patients showed preoperative grade III varicoceles. In patients with a low sperm number before surgery, sperm count improved from 13 x 106 to 21 x 106 m1-1 （P〈 0.001）. The median value of the percentage of progressive motile forms at 1 h improved from 25% to 45% （P 〈 0.001）. Percentage of normal forms increased from 17% before surgery to 35% 1 year after the procedure （P 〈 0.001）. In the subgroup of the 168 infertile patients, 52 （31%） fathered offspring at a 12-month-minimum follow-up. Therefore, ASS is an effective minimal invasive treatment for varicocele with low recurrence/persistence rate.

The role of copper element has been an increasingly relevant topic in recent years in the fields of human and animal health, for both the study of new drugs and innovative food and feed supplements. This metal plays an important role in the central nervous system, where it is associated with glutamatergic signaling, and it is widely involved in inflammatory processes. Thus, diseases involving copper(Ⅱ) dyshomeostasis often have neurological symptoms, as exemplified by Alzheimer's and other diseases(such as Parkinson's and Wilson's diseases). Moreover, imbalanced copper ion concentrations have also been associated with diabetes and certain types of cancer, including glioma. In this paper, we propose a comprehensive overview of recent results that show the importance of these metal ions in several pathologies, mainly Alzheimer's disease, through the lens of the development and use of copper chelators as research compounds and potential therapeutics if included in multi-target hybrid drugs. Seeing how copper homeostasis is important for the well-being of animals as well as humans, we shortly describe the state of the art regarding the effects of copper and its chelators in agriculture, livestock rearing, and aquaculture, as ingredients for the formulation of feed supplements as well as to prevent the effects of pollution on animal productions.

Mobile communications have come a long way since the early days of cellular networks. Today, we are on the cusp of a new generation of wireless technology,known as sixth-generation(6G), which is expected to significantly improve upon the performance, efficiency and functionality of its predecessor, 5G. While 5G has already begun to transform the way we connect and communicate, 6G is poised to take these capabilities to the next level,with significant impact on industry and society [1].

Metabolic P systems are a special class of P systems which seem to be adequate for expressing biological phenomena, especially, metabolism and signaling transduction. Basic motivations for their introduction are given and their main aspects are explained by means of an example of biological modeling. A new kind of regulation mechanism is outlined, which could be the basis for a more efficient construction of computational models from experimental data of specific metabolic processes.

We investigate several Hamiltonians for a free particle in a one-dimensional box, in the context of supersymmetric quantum mechanics. Specifically, we study this problem with the Neumann boundary condition, the periodic and antiperiodic boundary condition, and some mixed and complex boundary conditions. This is achieved by using an approach recently proposed which expresses the factorization of the partner Hamiltonians in terms of the probability density and current for the ground-state eigenfunction of one of them.

Let R be a prime ring, L a non-central Lie ideal of R and g a non-zero generalized derivation of R. If g acts as a Jordan homomorphism on L, then either g（x） = x for all x ∈ R, or char（R） = 2, R satisfies the standard identity s4（x1, x2, x3, x4）, L is commutative and u2 ∈ Z（R）, for any u C L. We also examine some consequences of this result related to generalized derivations which act as Jordan homomorphisms on the set [I, I], where I is a non-zero right ideal of R.
