The eusocial non-code: Unveiling the impact of noncoding RNAs on Hymenoptera eusocial evolution.

Eusociality, characterized by reproductive division of labor, cooperative brood care, and multi-generational cohabitation, represents a pinnacle of complex social evolution, most notably manifested within the Hymenoptera order including bees, ants, and wasps. The molecular underpinnings underlying these sophisticated social structures remain an enigma, with noncoding RNAs (ncRNAs) emerging as crucial regulatory players. This article delves into the roles of ncRNAs in exerting epigenetic control during the development and maintenance of Hymenopteran eusociality.

Shotgun Metagenomics Reveals Minor Micro""omes Diversity Defining Differences between Larvae and Pupae Brood Combs.

Bees represent not only a valuable asset in agriculture, but also serve as a model organism within contemporary microbiology. The metagenomic composition of the bee superorganism has been substantially characterized. Nevertheless, traditional cultural methods served as the approach to studying brood combs in the past.

Taste and pheromonal inputs govern the regulation of time investment for mating by sexual experience in male Drosophila melanogaster.

Males have finite resources to spend on reproduction. Thus, males rely on a 'time investment strategy' to maximize their reproductive success. For example, male Drosophila melanogaster extends their mating duration when surrounded by conditions enriched with rivals.

Micro"bee"ota: Honey Bee Normal Microbiota as a Part of Superorganism.

Honey bees are model organisms for microbiota research. Gut microbiomes are very interesting for surveys due to their simple structure and relationship with hive production. Long-term studies reveal the gut microbiota patterns of various hive members, as well as the functions, sources, and interactions of the majority of its bacteria.

Achilles tendon thickness normalized to body surface area as a marker of asymptomatic peripheral arterial disease.

Objectives: The normalisation of Achilles tendon thickness (ATT) to anthropometric parameters may increase the diagnostic efficiency of the assessment of ATT. The aim of this study was to compare the diagnostic value of AT dimensions depending on their normalization to body surface area (BSA) in patients with asymptomatic peripheral arterial disease (PAD).

Methods: All patients underwent duplex scanning of the carotid arteries and the lower limb arteries.

Factors associated with atherosclerotic plaque echogenicity in patients aged 40-64 with carotid atherosclerosis.

Aim    To identify clinical and laboratory indexes related with the atherosclerotic plaque (ASP) echogenicity based on results of the analysis of grey-scale median (GSM) in patients aged 40-64 years.Material and methods    The study included patients aged 40-64 years with carotid atherosclerosis. The carotid duplex scanning was performed for all patients.

Compressional wave velocity measurements on mafic-ultramafic rocks under high aqueous fluid pressure and temperature help to explain low-velocity zones in the lithosphere.

Deep seismic studies have revealed that low-velocity zones mainly occurred in the continental lithosphere at the depth of 100-150 km. Their origin has not been clearly explained yet. The article demonstrates the possible scale of Vp changes in crystalline rocks of different composition.

A Cellular Automata Approach for the Modeling of a Polyamide and Carbon Aerogel Structure and Its Properties.

In this work, a cellular automata (CA) approach was used to generate 3D structures of polyamide and carbon aerogels. Experimental results are used as initial data for materials' digital representations and to verify the developed CA models. Based on the generated digital structures, a computer study of aerogels' mechanical properties was conducted.

Cellular Automata in Chemistry and Chemical Engineering.

We review the modern state of cellular automata (CA) applications for solving practical problems in chemistry and chemical technology. We consider the problems of material structure modeling and prediction of materials' morphology-dependent properties. We review the use of the CA approach for modeling diffusion, crystallization, dissolution, erosion, corrosion, adsorption, and hydration processes.

Achilles Tendon Thickness Is an Independent Predictor of Carotid Atherosclerosis and Is Associated With a Carotid Plaque Burden.

The aim of the study was to research the relationship between carotid atherosclerosis markers and ultrasound parameters of Achilles tendons (AT). The study included 150 patients at high and very high cardiovascular risk (CVR). All patients underwent a carotid ultrasound scanning.

Reduced infectivity in (Trematoda, Himasthlidae) cercariae with deviant photoreaction.

Digenean larvae of hermaphroditic generation - cercariae - are known to be polymorphic at genetic and behavioural levels. Cercariae arise as a result of parthenogenetic reproduction of intramolluscan stages, and represent a clone if a snail was infected with a single miracidium. Here we investigated cercarial clones of Himasthla elongata - namely, the infectivity of cercariae with normal (negative) and deviant (positive) photoreaction.

Unlabelled: The relaxation processes of hybrid organic-inorganic polymer nanosystems (OIS) synthesized by joint polymerization of organic and inorganic components were studied using methods of differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA), and broadband dielectric relaxation spectroscopy (DRS). The organic component was a mixture of two products: high-molecular-weight macrodiisocyanate (MDI) with low reactivity and low-molecular-weight isocyanate-containing modifier poly(isocyanate) (PIC) with high reactivity. Sodium silicate (SS) was used as inorganic component.

[Determination of circulation disturbance in the rat lungs in modelling of chronic obstructive disease].

Development of chronic obstructive pulmonary disease (COPD) involves not only the bronchial and respiratory areas of the lungs, but also the system of pulmonary circulation, which begins with the defeat of capillary blood flow. One of radiological methods of studying lung microcirculatory functions is perfusion scintigraphy. We designed the technique of radiological examination and identified its abilities in determination of the role of vascular dysfunctions in experimental model of development of COPD.
