En aquesta tesi s'han estudiat les propietats antitumorals d'una variant de la ribonucleasa pancreàtica humana anomenada PE5 que incorpora un senyal de localització nuclear. Aquest estudi mostra que PE5 indueix l'apoptosi ...
L'ús d'esperma criopreservada en la inseminació artificial (IA) d'espècies d'interès productiu permet un major control sanitari i la creació de bancs de germoplasma d'alt valor genètic, entre d'altres avantatges. En el ...
Currently, automatic analyzers based on highly accurate methods can determine hematologic parameters in a fast and reliable way which is important to detect abnormalities in blood cells. In laboratories with a high care ...
El present treball analitza la morfologia espermàtica de l'ejaculat de Sus domesticus, la histologia del conducte epididimari i la qualitat de l'esperma epididimari. El material d'estudi prové de mascles reproductors porcins ...
Boar semen is not collected under sterile conditions,so boar ejaculates are commonly contaminated with a broad range of microorganisms, which may affect sperm quality and lead to a low reproductive performance and severe ...
En aquesta tesi s'ha caracteritzat la ruta d'internalització de l'onconasa, una RNasa citotòxica. Els resultats indiquen que l'onconasa entra a les cèl·lules per la via dependent de clatrina i del complex AP-2. Seguidament ...
Colorectal Cancer is the main type of cancer in Spain. Up to 90% of the cases are sporadic in nature and its aetiology is still unclear. It is supposed to be a multi-factorial disease, where factors play an important role ...
El disseny i la producció de zimògens de ribonucleases que puguin ser específicament activats per la proteasa d’un patogen, constitueix un enginyós mecanisme per controlar la seva activitat enzimàtica i, conseqüentment, ...
Chromosome abnormalities are one of the most important causes of congenital disorders. The main goal of this research is to give a broad view of the use and evolution of prenatal and postnatal cytogenetic diagnosis in ...
This thesis is about challenges that currently concern in vitro production (IVP), sex determination procedures and sex-related survival of in vitro-produced porcine embryos. Specifically, the current thesis develops a new ...
Pancreatic ductal adenocarcinoma (PDA) presents a dismal prognosis mainly due to its delayed diagnosis, its aggressiveness, and resistance to existing therapies. Aberrant glycosylation and, in particular, the overexpression ...
S'estudia la histologia normal de la paret corporal d'Hirudo medicinalis i els canvis morfogenètics que es donen durant el procés de cicatrització de ferides per incisió, cauterització i nitrat de plata.<br/>El procés de ...
Male infertility is a global health problem affecting one in four infertile couples. This also has a negative repercussion on the animal breeding industry, where infertility has a detrimental impact on their balance sheets. ...
The aim of this doctoral thesis was to unravel mechanisms underlying primary resistance to trastuzumab regarding a putative new breast cancer subtype with mixed basal & ErbB2+ molecular features. Using the JIMT-1 breast ...
For many years, reproductive outcomes were considered as being solely determined by the genome of oocytes and sperm. Yet, in the last decades, many other female and male factors have also been found to be relevant. Focusing ...
The spermatozoon is a highly specialised cell that travels along the female reproductive tract to deliver its genetic information into the oocyte. During this journey, the interaction with the varying environment is crucial ...
Amb la finalitat d'aprofundir en les bases moleculars de la citotoxicitat de les ribonucleases pancreàtiques, es van construir variants derivades de l'HP-RNasa seguint dues estratègies. En la primera, es van generar variants ...
Male fertilising capacity has traditionally been predicted by the assessment of sperm concentration, motility and morphology. During the last few decades, however, research has been particularly focused on the analysis of ...
Este trabajo demuestra que los genes que codifican para los enzimas beta-galactosido alfa-2,3-sialiltransferasa 3 (ST3Gal III), y en menor medida beta-galactosido alfa-2,3-sialiltransferasa 4 (ST3Gal IV), están directamente ...
Cancer is the leading cause of death due to non-communicable diseases worldwide. Despite the advances in the development of new antitumor drugs, there are still problems such as the resistance that tumor cells acquire ...
