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.

In the research it was possible to obtain a symbiotic drink, starting from whey, which was subjected to a pasteurization followed by a protein separation using the isoelectric point of the serum, thus precipitating the β - lactoglobulin and separating it by transfer, using two types of Ferments 1. (YO-MIXTM 495), and 2. (LAT BY 9R), these ferments are inoculated at 42 and 37 ° C. Maintaining these temperatures during 3:30 and 6:00 hours respectively. The incorporation of inulin and oligofructose, is 0.85%, thus acquiring a percentage of 0.58% of oligofructose in the lacto serum drink. A bifactorial design was applied: A is the percentage of whey (100, 75 and 50) and B is the yeast, with a total of 18 treatments, the analyzes were:protein, solids, lactic acid bacteria, Lactic acid, coliforms. Statistical results show that the best treatment for serum lactobacillus is 100% A1B2 and LAT B...

factor involved in controlled muscle of shrimp drying permits process optimisation and assists in design of suitable dryers. The study undertook two stages: first a thermal pre-treatment submerging the whole shrimp in water at 90ºC for 90 seconds, were the orange colour and textura was improved. Was used then the sample underwent osmotic dehydration in ternary solution of 20% suerosa and 20%of NaCI ( % weight) under agitation at 120 rpm for 30 minutes to temperatura of 20ºC. The second stage was the drying where the experimental curves were obtained in laboratory dryer under different drying conditions from 40, 50 and 60ºC , and air velocity from 0.5, 0.8 and 1.1 m/s. during this whole process the time of drying was controlled at regular time in someway, the loss weight produced by the evaporation of water contained in the muscle was controlled. With this parameter the product was obt...

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...

Sweet cucumber (Solanum muricatum) sect. Basarthrum is a neglected horticultural crop native to the Andean region. It is naturally distributed very close to other two Solanum crops of high importance, potatoes, and tomatoes. To date, molecular tools for this crop remain undetermined. In this study, the complete sweet cucumber chloroplast (cp) genome was obtained and compared with seven Solanaceae species. The cp genome of S. muricatum was 155,681 bp in length and included a large single copy (LSC) region of 86,182 bp and a small single-copy (SSC) region of 18,360 bp, separated by a pair of inverted repeats (IR) regions of 25,568 bp. The cp genome possessed 87 protein-coding genes (CDS), 37 transfer RNA (tRNA) genes, eight ribosomal RNA (rRNA) genes, and one pseudogene. Furthermore, 48 perfect microsatellites were identified. These repeats were mainly located in the noncoding regions. Who...

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...

Ullucus tuberosus is an Andean region crop adapted to high-altitude environments and dryland cultivation. It is an essential resource that guarantees food security due to its carbohydrate, protein, and low-fat content. However, current change patterns in precipitation and temperatures warn of complex scenarios where climate change will affect this crop. Therefore, predicting these effects through simulation is a valuable tool for evaluating this crop’s sustainability. This study aims to evaluate ulluco’s crop yield under dryland conditions at 3914 m.a.s.l. considering climate change scenarios from 2024 to 2100 by using the AquaCrop model. Simulations were carried out using current meteorological data, crop agronomic information, and simulations for SSP1-2.6, SSP3-7.0, and SSP5-8.5 of CMIP 6. The results indicate that minimum temperature increases and seasonal precipitation exacerbati...

The objective of this study was to determine the prevalence of reactive infectious markers at the Centro Hemodador Regional de Loreto from november 2023 to december 2024. A quantitative, descriptive, and retrospective approach was applied. Data from 7,767 donors were analyzed, who underwent screening with infectious markers using the chemiluminescence technique, allowing for a detailed analysis of the prevalence and distribution of these agents in the donor population. Seven mandatory markers in blood banks were evaluated, and for the purposes of the study, sociodemographic variables such as age, sex, marital status, origin, ABO group, and Rh factor were categorized. The overall prevalence of reactive markers was 8.1%. The most frequent marker was anti-HBcAb (4.49%), followed by anti-syphilis (1.47%), anti-HCV (0.61%), anti HTLV-I/II (0.57%), anti-HIV 1-2 (0.37%), HBsAg (0.22%), and anti...

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...
