Hygromycin A (HygA) binds to the large ribosomal subunit and inhibits its peptidyl transferase (PT) activity. The presented structural and biochemical data indicate that HygA does not interfere with the initial binding of aminoacyl-tRNA to the A site, but prevents its subsequent adjustment such that it fails to act as a substrate in the PT reaction. Structurally we demonstrate that HygA binds within the peptidyl transferase center (PTC) and induces a unique conformation. Specifically in its ribosomal binding site HygA would overlap and clash with aminoacyl-A76 ribose moiety and, therefore, its primary mode of action involves sterically restricting access of the incoming aminoacyl-tRNA to the PTC.

Drying is a method to preserve fruits, vegetables and fish by reducing their volume, their weight. Drying involves the application of energy to vaporize and mobilize the moisture content within porous products. During this process, heat and mass transfer occur simultaneously. The quality of dehydrated fruits, vegetables, and aromatic herbs is a problem closely related to the development and optimization of new drying techniques. This research work addresses the common drying methods applied to fruits, grains, fish and nutrients in relation to possible options to improve the quality of dried products using different drying techniques or their combination. In general, the drying technique is different for each of the materials studied and specific conditions should be recommended after a proper evaluation of the drying protocols. However, a novel or combined technique must ensure a high qu...

La neurocisticercosis (NCC) es una enfermedad causada por la presencia de cisticercos (larvas) de Taenia solium en el cerebro por la ingesta de huevos de este helminto parásito (García et al., 2020). La NCC provoca sintomatología neurológica como epilepsia, presión intracraneal e incluso la muerte (Son et al., 2019). Los cisticercos pueden mantenerse viables por varios meses o años sin producir inflamación ni síntomas (Gutierrez-Loli et al., 2017). No se ha logrado explicar qué le permite a la larva viable de T. solium evadir la respuesta inmune de su hospedero. T. solium libera productos-derivados-de-helmintos (HDP por sus siglas en inglés), entre ellos RNA y proteínas, a través de vesículas extracelulares (EVs) (Zakeri et al., 2018). Los HDP incluyen microRNAs (miRNAs), RNAs regulatorios muy cortos con una función conservada en la regulación postranscripcional en eucario...

Cattle spread throughout the American continent during the colonization years, originating creole breeds that adapted to a wide range of climate conditions. The population of creole cattle in Peru is decreasing mainly due to the introduction of more productive breeds in recent years. During the last 15 years, there has been significant progress in cattle genomics. However, little is known about the genetics of the Peruvian creole cattle (PCC) despite its importance to (i) improving productivity in the Andean region, (ii) agricultural labor, and (iii) cultural traditions. In addition, the origin and phylogenetic relationship of the PCC are still unclear. In order to promote the conservation of the PCC, we sequenced the mitochondrial genome of a creole bull, which also possessed exceptional fighting skills and was employed for agricultural tasks, from the highlands of Arequipa for the firs...

The population of Peruvian creole cattle (PCC) is decreasing mainly due to the introduction of more productive breeds in recent years. We report the complete mitochondrial genome sequence of a PCC bull for the first time. This genome was 16,339 bp in length with the base composition 31.43% A, 28.64% T, 26.81% C, and 13.12% G. It contained 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and a control region. Among the 37 genes, 28 were positioned on the H-strand and 9 were positioned on the L-strand. The most frequently used codons were CUA (Leucine), AUA (Isoleucine), AUU (Isoleucine), AUC (Isoleucine) and ACA (Threonine). Maximum likelihood analysis clearly demonstrated that PCC are strongly related to a native African breed, giving insights into the maternal ancestry of PCC. The annotated mitochondrial genome of PCC would serve as an important genetic data set for...

Introducción: El raquitismo hipofosfatémico ligado al X (RHLX) es el tipo hereditario más frecuente de raquitismo. Ocurre por una mutación en el gen PHEX localizado en el cromosoma 22, que conlleva a un aumento del factor de crecimiento de fibroblastos 23 (FGF-23), cuya función radica en inhibir la reabsorción de fósforo a nivel renal. Por ello, esta patología se caracteriza por una pérdida excesiva de fósforo, lo que ocasiona manifestaciones clínicas que afectan sobre todo región craneal, deformidad de miembros y lesiones dentarias. En Perú se considera una enfermedad huérfana y se estima que 1 de cada 20,000 personas presentan a enfermedad, por lo que no se tiene mucha bibliografía al respecto que determine la prevalencia o el perfil de los pacientes con esta enfermedad. Objetivo: Describir el perfil genético de los pacientes con diagnóstico de raquitismo hipofosfatém...
