Sleep is vital for all mammals including humans, its distortion implies different health risks and pathologies such as depression, and cardiovascular diseases, and in the end, it can lead to death. In this sense, it is important to find the molecular bases of sleep, among them the genes and their proteins that play a key role in the homeostasis of the living being. Information was collected using the PubMed/Scopus databases in English with a 10-year history using the PICO methodology to determine the words P=Genes, I=Molecular basis, C=Not applicable, O=Sleep. Original articles were determined into two large groups, among these are the "Clock Genes" and other "Genes and Proteins" related to sleep. Among the important clock genes identified are those linked to dopamine (DRD 2) and (DAT 1) and other genes such as pdm3 that participate in the genesis of the innervation of the dopaminergic system and the ANXA3 and 17GAM genes which has shown that overexpression of these is related to sleep deprivation. Understanding the molecular bases of sleep and its gaps still to be studied are key to future studies such as identifying targets and drugs to treat sleep disorders.

Chronicle of the Conservation of Peruvian Biodiversity (2022) is the book written by Marc Dourojeanni, who recounts the efforts made, in the last 60 years, by scientists, environmentalists, managers, politicians, and park rangers, in favor of the conservation of flora and fauna species (wildlife) in natural areas protected by the State, private conservation areas, species management practices in terrestrial environments, continental waters and the sea.

We observed and captured an individual of Coccycua cinerea Vieillot, 1817 in Corozal, Uracoa location, Uracoa municipality, near conflux of Uracoa River and Mánamo spout, in southern Monagas state, adjacent to Orinoco river delta, Venezuela. Diagnostic identification: Bill is ll-dark, short, and curved. Dark iris and suggestive eye ring. Brown tail most dark towards the tips and black at the rear, and ending in white tips, and black bars in the lower part.  This austral migrant bird represents the first and only record for Venezuela and the northernmost to South America.

The "Pantanos de Villa" wetland is a Wildlife Refuge (RVSPV), in Lima, Peru for many resident and migratory birds and is an important space for their development because it provides favorable spaces for their feeding and reproduction. Currently there is no delimitation for the breeding colonies of birds in the RVSPV Laguna Mayor, due to the lack of studies on nesting sites. Therefore, the objective was to evaluate the nesting sites and the reproductive behavior of three species of birds that nest in the Laguna Mayor. Monitoring was carried out once a week between the months of March and May 2022, and the nesting sites of three species were recorded: Nannnopterum brasilianum "Neotropical Cormorant", Chroicocephalus cirrocephalus "Gray-headed Gull" and Anas bahamensis "white-cheeked pintail", of which the microhabitat of the nest, the vegetation cover, characteristics of the eggs and chicks and biological factors such as predation are described.

This study aimed to compare two staining methods for detecting nucleolar organizing regions (NOR) of acrocentric chromosomes in the Cytogenetics Laboratory of INMP (“Instituto Nacional Materno Perinatal”), Lima, Peru.  A total of 60 metaphases with normal karyotypes were analyzed, of which 30 were stained for each method: Kodama et al. and Howell & Black, respectively. The recognition efficiency and staining intensity of these regions were evaluated by each technique based on the count of NORs Ag (+); Likewise, the staining and integrity of the chromosomes were evaluated and the differences between these two methods were established. No significant differences were found regarding the number of stained regions with both techniques; however, in staining intensity and chromosomal quality, the Howell & Black method was superior. It is concluded that the Howell & Black method generates better results for the cytogenetic analysis of these regions.

Francisco Macián has been considered by the critics as one of the main figures of Spanish animation of all times. He has been author, among others, of some of the most popular commercials done by Moro Studios —such as La canción del Cola Cao and Sol de Andalucía embotellado (de Tío Pepe). He is the inventor of M-Tecnofantasy system, and director of one of the best European animations done during the postwar, El mago de los sueños (The Wizard of Dreams, 1966), performed by the famous family Telerín. These achievements and professional milestones have been thoroughly studied in various monographs and even in doctoral thesis. Saying this, this paper brings to the fore two new unexplored elements of Macián’s professional career. Namely, the potential discovery of one his first productions: El justiciero del espacio, and the identification of Dibujos Animados MAPA as his first business structure before the establishment in 1955 of the popular Estudios Macián. These discoveries are connected to the global emergence of home cinema as a toy, which Macián’s inseparable friend, Jaume Papaseit, was also part of. This emergence responded to the popular demand of projectors Jefe by Industrias Saludes, S.A. It was in this small sector of the movie industry, used as an experimentation field, where Macián prepared his leap to the big screen. This paper is the result of a research project on the work of Pérez Arroyo, the king of postwar home animated cinema in Spain, which was done in conjunction with several Spanish film libraries.

After examining the significant links between the neo-noir essence and the shift made by Argentine cinema at the end of last century, when the heterogeneous New Argentine Cinema (NAC) was searching for disruptive cinematic forms and, in certain cases, they were found in film genre hybridity and subversion, the aim of this paper is to analyze the way in which neo-noir’s generic polyvalence, through some of its thematic and aesthetic postulates, influenced various significant examples of the NAC. The two cases under review are Pizza, birra, faso (Bruno Stagnaro and Adrián Caetano, 1998) and El bonaerense (Pablo Trapero, 2002). Their quasi-documentary style, defined as «neo-neorealist» by Joanna Page, establishes a dialogue with the social distress that took place during pre- and post-crisis Argentina after 2001, more effectively conveyed thanks to the influence of neo-noir and its hybridity

In this paper we will analyse three short films directed by Leonardo Goilenberg, which are the result of the work of Teatro Libre Argentino de Títeres (TLAT) —formed by the artists Mane Bernardo and Sarah Bianchi, and the company Cinepa. They were created for the domestic projectors CinepaVisión, entitled: Red Riding Hood (Caperucita Roja, 1949), The Three Bears (Los tres ositos, 1950) and The Savior Gnomes (Los gnomos salvadores). We use as a starting point the hypothesis that the freedom offered by a medium such as home projectors —halfway between cinematographic projections and objects for domestic consumption, later associated with television—, allowed these artists to carry out an experimental work that locates these short films in a zone of tension that combines elements associated with puppet animation cinema and those elements close to the filmed theater. Bearing this in mind, we will begin by outlining the trajectory of TLAT, emphasizing its conception of experimental theater. Then, we will formally analyse these three short films with the aim to reflect on the presence of puppets in cinema and the possible links between them and animation, which will ultimately allow us to arrive at a (re)definition of puppet cinema.
