The growing demand for alternative protein sources in animal feed has increased interest in earthworm meal (EM) as a sustainable input in poultry production. This study evaluated the effect of its inclusion in the diet of native chickens on productive and economic parameters. Four treatments were applied with inclusion levels ranging from 0 to 12 % EM, recording cumulative feed intake, body weight, weight gain, feed conversion ratio, mortality, and profitability over a 25-day period. In addition, the nutritional composition of EM was determined through proximate analysis. The results showed significant differences (p < 0.05) in body weight, with a progressive increase from 355.51 g to 427.86 g. Feed conversion improved from 2.40 to 2.08 as the inclusion level increased, while feed intake showed an upward trend without statistical differences. No mortality was recorded and feathering w...

Childhood malnutrition and anemia constitute a serious public health problem, driving the search for foods enriched with protein and vitamin supplements to help reduce this issue. In this context, the present research was developed with the objective of creating a protein rich, probiotic, and energy boosting becerage based on mango (Mangifera indica), whey, and Lactobacillus casei. Five treatments were formulated with different proportions of mango pulp and whey (T1: 90/10, T2: 70/30, T3: 50/50, T4: 30/70, and T5: 10/90, with two replicates per treatment. The bererages were inoculated with L. casei, and the pH was monitored every 48 hours for 14 days. Aprogessive decrease in pH from 5.0 - 6.0 to aproximately 4.0 was observed, demonstrating the viability and stability of the probiotic during storage. Regarding protein composition, treatment T5 reached 4.92 g/100 ml of protein, while treat...

Technological advances applied to preclinical and clinical scientific research have significantly enabled the broadening of knowledge regarding neoplastic cells biology in the last two decades. The characterization of genetic and epigenetic alterations which are involved in carcinogenesis; the molecular subclassification of tumors; the understanding of normal and neoplastic cells interactions in the tumor microenvironment; and the description of molecular bases that explain the influence of factors such as exercise, diet and microbiota composition on cancer progression have contributed to support the importance of precision medicine in cancer. The present research reviews the so-called "hallmarks of cancer" and their "enabling characteristics", i.e. those properties inherent to cancer cells that allow to evade intrinsic and extrinsic mechanisms of carcinogenesis control. This paper is a ...

In the last twenty years, the number of complete genomes that have been sequenced and deposited in data banks has grown dramatically. This abundance in sequence information has supported the creation of the discipline known as paleogenetics. In this article, without going into complex algorithms, we present some key concepts for understanding how proteins have evolved in time. We then illustrate how paleogenetic analysis can be used in biotechnology. These examples highlight the connection between chemistry and biology, two disciplines that twenty years ago seemed to be more different than what they seem to be today.

Since their origins, vascular land plants have coexisted with a wide variety of bacteria and fungi. When insects appeared, they also maintained a close relationship with them, taking on a big role with the arrival of flowering plants in the early Cretaceous period. The different evolutionary processes have led to the development of a series of interspecific interactions; some of them beneficial for both parties, such as the various pollination mechanisms throu- gh insects in many plant species. At the same time, other types of interactions have emerged with species capable of producing severe diseases in different sections of the plant. This evolutionary pressure with the inability of a defense offered by locomotion, and the lack of a defense system based on antibodies, have been the main responsible for the appearance of com- plex defense mechanisms in plants, many times rapid and effec...

Con el pasar de los años, la consciencia por la salud física y estética ha aumentado, producto del auge del estilo de vida saludable. Con esto, las cadenas de suplementos deportivos se han visto favorecidas al poder incrementar las ventas de sus productos a nivel mundial; sin embargo, en Perú se enfoca principalmente en los sectores altos, con mayor poder adquisitivo. Lamentablemente, muchas personas de los estratos socioeconómicos más bajos no tienen acceso a suplementos deportivos que permitan complementar su entrenamiento físico o deporte. Sin embargo, en el caso del Perú se cuenta con una realidad en la cual la mayor parte de los suplementos deportivos, puntualmente marcas de proteína de calidad son importadas y no de fabricación local, destacando marcas como Gold Standard Whey o Carnivore. En el presente proyecto de prefactibilidad se busca aprovechar el recurso dosidicus ...

Proteins are versatile biopolymers in living systems that show a great diversity of functions based on the order of their amino acids. Many protein functions, whether mechanical or regulatory, emerge from interactions with other proteins and macromolecules. This dissertation describes the development and adaptation of new computational models to investigate structural and dynamic properties of protein interactions. Two main systems were investigated: the regulation of the actin cytoskeleton and the control of DNA transcription by nuclear factor B (NF-kB). During the study of the regulation of the actin cytoskeleton, mechanical and dynamic properties were estimated using polymer theory. A simplified model of actin filament polymerization was developed. Through simulations, it was shown that actin networks containing Arp2/3 undergo abrupt releases of tension. For the study of DNA interacti...
