On features of the life cycle of humpback shrimp Pandalus hypsinotus (Decapoda, Pandalidae) in the Tatar Strait
Authors: Yuriev D. N.
Published: April 2024

The study is based on biological analyses of > 80,000 ind. of Pandalus hypsinotus collected in trawl surveys and trap fishery in the Tatar Strait in 2010–2022. Due to the lack of age-recording structures, the size-age structure of shrimp is usually determined by various statistical methods, each of which has some limitations and drawbacks. The modal analysis of size-sex composition dynamics is used in this study, including tracing the growth of strong year-classes. The analysis takes into account the dynamics of major seasonal events such as group molting, spawning, and larval hatching. The reproductive cycle of females is assumed to be 2 years. Based on results of the analysis, the life cycle of humpback shrimp in the Tatar Strait is as follows. After the larvae hatch from eggs in April-May, immature shrimp spend the first year of their life at the depths < 70 m, where they reach the carapace length of 9–15 mm, with a modal size of 11–12 mm. In the second year, they grow to the length of 20–22 mm, on average, then become males and migrate to deeper layer where join the adults. Further growth is described on the data for the strong year-class of 2010: the modal size of males reaches 26–27 mm at age 3 years, 29–30 mm — at age 4, 32–33 mm — at age 5, and 35–36 mm — at age 6. Gender transition of shrimp begins at age 5+, but most males become hermaphroditic at the age 6+. The modal size of intersex hermaphrodites ranges from 37 to 39 mm. At the age of 6 years and 9 months, the intersexes spawn en masse and transform into females. The first larval hatching of new females occurs after 15 months, i.e. at exactly 8 years of age. At least three cycles of spawning (larvae release) are assumed for females, taking into account their polymodal size composition and dynamics of their size increments per molt by age. In assumption of 2-year reproductive cycle, the female stage lasts 6 years. Thus, the total life span for the most of humpback shrimps is estimated to be 12 years (6 years before gender transition and 6 years after). Apparently, a small number of them live 14 years and spawn four times, and some can live up to 16 years and spawn five times.

Published: April 2024

This paper evaluates the mechanical characteristics of laminated polymer nanocomposites modified by graphene oxide. The nanocomposite samples were fabricated using the traditional hand-layup method (HLM) at three different weight percentages (1\%, 2\%, and 3\%). Tensile and flexural tests analyzed the mechanical behavior of the produced composite. The viscoelastic and thermal properties of the nanocomposite samples are calculated using dynamic mechanical analysis (DMA). Scanning electron microscopy (SEM) reveals the failure processes on the broken surfaces of the nanocomposite specimens. By enhancing the mechanical properties of structural components, the Graphene Oxide (GO) additives in composites make them more efficient than pure samples.

In this report, we show that modification of the X counterions constitutive of [Ru(bpy)3](X)2 photocatalysts modulates their catalytic activities in intermolecular [2+2] cycloaddition reactions operating through triplet-triplet energy transfer (TTEnT). Particularly noteworthy is the dramatic impact observed in low-dielectric constant solvent over the excited state quenching coefficient, which varies by two orders of magnitude depending on whether X is a large weakly bound (BArF-) or a tightly bound anion (TsO-). In addition, the counterion identity also greatly affects the photophysical properties of the cationic ruthenium complex, with [Ru(bpy)3](BArF4)2 exhibiting the shortest 3MLCT excited state lifetime, highest excited state energy and photostability, enabling remarkably enhanced performance (up to >1000 TON at low 500 ppm catalyst loading) in TTEnT photocatalysis.
Binding Study of Berenil and d(CGCGAATTCGCG)2 and d(CGCAAATTTGCG)2 DNA Dodecamers by Isothermal Titration Calorimetry and Molecular Docking Simulations

Published: April 2024

Berenil, an anti-trypanosomal agent, is a dicationic bis-benzamidine that has been classified as a minor groove binding ligand in AT-rich regions of DNA. However, previous studies have suggested that berenil can bind to various DNA double strands exhibiting both intercalative and minor groove binding modes. In this work we present a biophysical study analyzing the interaction between berenil and two synthetic DNAs that suggests that this molecule shows a mixed bind behaviour when binding to double stranded DNA. It is possible that more than one berenil molecule can bind to DNA dodecamers double strands. The second molecule may be interacting through intercalation. The data from isothermic calorimetric titrations at 298 K were analyzed by Wiseman Isotherm and classical thermodynamic equations. Thermodynamic parameters for complexation between the two DNAs were obtained by ITC experiments and Autodock calculations. The results show that the intercalative effect of the molecule is entropically driven.

Published: April 2024

The design of high-performing OSC materials is an active field of research. Many review articles summarize certain subclasses of NFAs, however, no broad overall analysis has been performed on the photovoltaic impact of chemical modifications made. This meta-analysis investigates various molecular design strategies for NFAs and donors and their effects on OSC device performance. Using a new dataset containing 1975 NFA/donor pairs, we performed matched-pair analysis on many design strategies to try to discern whether it has a significant impact on PCE. For the NFA, the class and size of the NFA, heteroatom substitution, types of rings and their sequence in the fused core, side chains, halogenation of terminal groups, and the presence of a pi-bridge are examined. For the donor polymers, the monomer identities, the types of side chains, and the halogenation of the polymer are examined. Some molecular design strategies that were found to significantly improve the PCE include branched instead of linear side chains, fused cores containing 8 rings, fused NFAs containing pyran, pyrrole, and selenophene, fused cores containing an odd number of thiophenes, the presence of pi-bridge units, halogenating the NFA and donor, incorporation of alkylsilyl chains instead of alkyl chains in donor polymers, as well as multiple others.

Controlling the rotation of carbon-carbon bonds, which is ubiquitous in organic molecules, to create functionality has been a subject of interest for a long time. In this context, it would be interesting to explore whether cooperative and collective rotation could occur if dipolar molecular rotors were aligned close together while leaving adequate space for rotation. However, it is difficult to realize such structures as bulk assemblies, since molecules generally tend to assemble into a closest packing structure to maximize intermolecular forces. To tackle this question, we examined an approach using a supramolecular scaffold composed of a tripodal triptycene, which has been demonstrated to strongly promote the assembly of various molecular and polymer units into regular “2D hexagonal packing + 1D layer” structures. We found that a molecule (1) consisting of a dipolar 1,2-difluorobenzene rotor sandwiched by two 10-ethynyl-1,8,13-tridodecyloxy triptycenes, successfully self-assembles into the desired structure, where the rotor units align two-dimensionally at a close interval of approximately 0.8 nm while having a degree of freedom for rotational motion. Here we describe the self-assembly behavior of 1 in comparison with the general trend in molecular self-assembly, as well as the motility of the aligned rotors investigated using solid-state 19F-MAS NMR spectroscopy.

Polymer electrolyte fuel cells (PEFCs) play a crucial role in approaching net-zero commitments due to their high-power density, rapid refuelling, and environmentally friendly operation. However, ensuring stable performance and durability relies on subtle water balance. Existing water management control strategies, including humidification, drainage, and cold starts, primarily depend on indirect feedback or calibration through the output voltage. The direct, real-time measurement of the water content inside a PEFC remains challenging, hindering the implementation of an efficient feedback control strategy for water management. To address this issue, synchronous measurement of neutron imaging and electrochemical impedance spectroscopy (EIS) is carried out at various water contents for the first time to the best of our knowledge. Machine learning is used to establish a nonlinear correlation between these two characterisation techniques. This enables the development of a more cost-effective and easily accessible real-time water content estimation technique suitable for high-power applications inferred from a universal EIS characterisation tool rather than relying solely on the limited availability of neutron imaging. This approach facilitates the optimisation and advancement of PEFCs.

Published: April 2024

BACKGROUND Pictorial health warnings on cigarette packages are a prominent and effective means of communicating the risks of smoking. They have broad reach in penetrating all sections of society. A specific health warning placed on tobacco product packages is considered an effective and low-cost method for increasing the knowledge and awareness among the community. Health awareness brings benefits at both the global and community levels.OBJECTIVE To explore the awareness of pictorial warnings on tobacco products among cigarette smokers in the urban and rural field practice area of a medical college in Karnataka.MATERIALS AND METHODS The study population comprised of 200 patients who were smokers in the age group of 20- 80yearsand had the smoking habit for a duration of more than six months and wereattending the outpatient department of the rural and urban health centre.The study period was for two months. Data collection was carried out using a semistructured questionnaire and included demographic details health-related issues of smoking awareness about pictorial warning and willingness to quit smoking.RESULTS Smoking was more among the middle age group 64 in both urban and rural area.46.5 smokers had the habit duration of smokingof more than 10 years. Neither their age literacy orsocio-economic status had any influence on theirawareness about pictorial warnings on the usage of tobacco products by the smokers. However a majority of them 48 from urban and 52 from rural background acknowledged that such powerful warnings were necessary and mandatory on tobacco products to help reduce smoking and quit smoking.CONCLUSION A positive response was shown by the general population for the implementation of pictorial warnings on tobacco products. A majority of the people strongly agreed for strong pictorial warnings which were diluted by government notifications in year 20082. Hence this study substantiates that smokers exhibited a positive response for inserting strong pictorial warnings on tobacco products and making it mandatory by law.nbsp

This qualitative study explored the potential sources of enjoyment and boredom in geography classes among Bhutanese
secondary school students. Utilizing open-ended surveys and semi-structured interviews, 206 participants aged 17 to 22,
predominantly from classes 11 and 12, shared their perspectives. The thematic analysis of the data revealed four sources
that contributed to students' enjoyment and boredom in geography classes. The findings on sources of enjoyment
included sources like enthusiasm, encouragement, friendliness and support which emerged as crucial contributors to
enjoyment. Moreover, video-integrated lessons, field trips, and challenging and hands-on activities, actively contributed
to positive emotional experiences. Additionally, individual interest in geography, aspirations to become geographers,
the relevance of materials and topics to learners' interests, were found to enhance geography class enjoyment.
Conversely, the findings on sources of boredom included monotonous teaching methods, poorly prepared lessons,
difficult content, dissatisfaction with presentation tasks, textbook-based activities, lack of interest in the subject or
negative moods linked to boredom. Altogether, this study contributes to the growing research trend, focusing on the
dimensions of students' emotions in the learning process. Based on the findings of the study, recommendations are made
and directions for future research are presented.
A Cross-Sectional Study on The Prevalence of Anemia in Maintenance Hemodialysis and Peritoneal Dialysis Patients and Its Related Factors
Authors: Huang Mingrong
Published: April 2024

Objective: To study the prevalence of anemia, the proportion of hemoglobin (Hb) levels, the treatment methods, and the influencing factors of Hb levels in maintenance hemodialysis (MHD) and peritoneal dialysis patients. Methods: In this study, 602 patients with maintenance hemodialysis and continuous ambulatory peritoneal dialysis were enrolled from December 2020 to December 2022 in our hospital, and their medical records were collected and summarized. The main contents included the patient’s gender, age, primary disease, dialysis duration, dialysis method, the use of erythropoietic stimulating agents (ESA), intravenous iron, and laboratory tests. A Hb index exceeding 110 g/L was set as the standard for the prevalence of anemia. Results: The rate of anemia in patients undergoing blood purification was 83%. The proportion of ESA use was 84.1%, and the proportion of iron use was 76.7%, of which the proportion of intravenous iron used was 17.0%, and the proportion of folic acid used was 28.3%. Conclusion: The incidence of anemia in MHD patients was relatively high, with a low proportion of patients reaching the standard Hb levels. Risk factors include albumin (ALB) levels, iron storage, white blood cells, C-reactive protein, cholesterol, etc. Nutritional support, iron supplementation, and prevention of micro-inflammatory reactions can effectively promote the improvement of Hb indicators in dialysis patients to prevent anemia.

Benign multicystic peritoneal mesothelioma (BMPM) is a rare tumor originating from peritoneal mesothelial cells. Here, we present a case of an 18-year-old male with right lower abdominal pain. Physical examination revealed a palpable mass with unclear boundaries. Laboratory tests showed elevated levels of monocytes and high-sensitivity C-reactive protein. CT scan revealed a cystic mass in the ileocecal region with multiple septations. Laparoscopic surgery confirmed a cystic solid mass resembling beads on the colon’s right side. Immunohistochemistry confirmed BMPM diagnosis. BMPM, especially in the ileocecal region, is uncommon and presents diagnostic challenges. Differential diagnosis includes lymphangioma, peritoneal metastasis, and malignant mesothelioma. CT findings, such as thin cyst walls and septations, aid in diagnosis. Recognition of BMPM’s imaging features improves diagnostic accuracy. Surgical resection remains the primary treatment. This case underscores the importance of considering BMPM in young male patients with abdominal pain and emphasizes the value of imaging modalities in accurate diagnosis and management.

The Sr3B2O6-YbBO3 diagram was constructed based on samples obtained by the solid-state synthesis. In the system YbBO3, Sr3Yb(BO3)3, Sr3Yb2(BO3)4 and Sr3B2O6 phases were identified by XRD analysis. Diffusion experiments showed formation of solid solutions between all compounds. These solid solutions demonstrate typical near-infrared luminescence in the range of 960–1020 nm, characteristic of Yb3+ and related to 2F5/2→2F7/2 transitions in ytterbium ions.

Background

As increasing antibiotic resistance in Acinetobacter baumannii poses a global healthcare challenge, understanding its evolution is crucial for effective control strategies.

Aim

We aimed to evaluate the epidemiology, antimicrobial susceptibility and main resistance mechanisms of Acinetobacter spp. in Spain in 2020, and to explore temporal trends of A. baumannii.

Methods

We collected 199 single-patient Acinetobacter spp. clinical isolates in 2020 from 18 Spanish tertiary hospitals. Minimum inhibitory concentrations (MICs) for nine antimicrobials were determined. Short-read sequencing was performed for all isolates, and targeted long-read sequencing for A. baumannii. Resistance mechanisms, phylogenetics and clonality were assessed. Findings on resistance rates and infection types were compared with data from 2000 and 2010.

Results

Cefiderocol and colistin exhibited the highest activity against A. baumannii, although colistin susceptibility has significantly declined over 2 decades. A. non-baumannii strains were highly susceptible to most tested antibiotics. Of the A. baumannii isolates, 47.5% (56/118) were multidrug-resistant (MDR). Phylogeny and clonal relationship analysis of A. baumannii revealed five prevalent international clones, notably IC2 (ST2, n = 52; ST745, n = 4) and IC1 (ST1, n = 14), and some episodes of clonal dissemination. Genes bla
OXA-23, bla
OXA-58 and bla
OXA-24/40 were identified in 49 (41.5%), eight (6.8%) and one (0.8%) A. baumannii isolates, respectively. ISAba1 was found upstream of the gene (a bla
OXA-51-like) in 10 isolates.

Conclusions

The emergence of OXA-23-producing ST1 and ST2, the predominant MDR lineages, shows a pivotal shift in carbapenem-resistant A. baumannii (CRAB) epidemiology in Spain. Coupled with increased colistin resistance, these changes underscore notable alterations in regional antimicrobial resistance dynamics.

Published: April 2024

En este trabajo se presenta el desarrollo de una aplicación móvil de realidad aumentada para la visualización de prendas en la industria textil, que tiene como objetivo incentivar la comercialización de productos infantiles. Actualmente la mayoría de las industrias textiles ofertan sus productos mediante catálogos de manera digital o físicos, sin embargo, en muchos casos sucede que las prendas cambian o varían en forma, tamaño y colores reales. Aunado a lo anterior, en dichos catálogos se limitan a una perspectiva en 2D, lo cual sería una limitante a la hora de tomar una decisión. Mediante el presente trabajo se pretende incorporar una experiencia envolvente para el usuario final, que le permita visualizar desde un enfoque con vistas tridimensionales, aspectos como  vista, color, textura y forma, y así incentivar a la compra de la prenda.
