Introduction Sperm DNA integrity is a crucial paternal factor affecting fertilization and pregnancy rates, as well as embryo development. Case The present case report describes the successful pregnancy after testicular sperm aspiration (TESA) combined with intracytoplasmic sperm injection (ICSI) (TESA-ICSI) in a couple where the male presented high sperm DNA fragmentation. In order to sort dama...

In recent years, the security of encryption and signature schemes in the presence of key-dependent plaintexts received attention, and progress in understanding such scenarios has been made. In this paper we motivate and discuss a setting where an adversary can access tags of a message authentication code (MAC) on key-dependent message inputs, and we propose a way to formalize the security of MA...

The in vivo studies of myocardial infarct using c-ki⁺/Lin⁻ cardiac stem cells (CSCs) are still in the early stage with margin or no beneficial effects for cardiac function. One of the potential reasons may be related to the absence of fully understanding the properties of these cells both in vitro and in vivo. In the present study, we aimed to systematically examine how CSCs adapted to in vitro...

In this thesis, we explore a topic within cryptography called Message Authentication Codes (MACs). A MAC is a collection of algorithms which allows A to send a message to B in such a way that B can be certain (with very high probability) that A did in fact originate the message. Let’s say A wants to send a message (string) M to B using a MAC. First A will run the “tag generation” algorithm on M...

This study investigated whether basic mathematics skills are associated with undergraduate psychology statistics course performance while simultaneously considering self-reported psychological/behavioral and demographic variables. Participants (n = 460) completed a Math Assessment for College Students (MACS), which included questions ranging from calculating percentages to graphical interpretat...

Objective The article synthesized the corporate social responsibility (CSR) initiatives of multinational alcohol companies (MACs) in Nigeria, highlighting their policy implications.
