Published: August 2020

Whether microplastics themselves or their interactions with chemicals influence the health and development of aquatic organisms has become a matter of scientific discussion. In aquatic environments, several groups of chemicals are abundant in parallel to microplastics. The tricyclic antidepressant amitriptyline is frequently prescribed, and residues of it are regularly found in surface waters. In the present study, the influence of irregularly shaped polystyrene microplastics (<50 µm), amitriptyline, and their mixture on early life-stages of brown trout were investigated. In a first experiment, the impacts of 100, 104, and 105 particles/L were studied from the fertilization of eggs until one month after yolk-sac consumption. In a second experiment, eggs were exposed in eyed ova stages to 105, 106 particles/L, to amitriptyline (pulse-spiked, average 48 ± 33 µg/L) or to two mixtures for two months. Microplastics alone did neither influence the development of fish nor the oxidative stress level or the acetylcholinesterase activity. Solely, a slight effect on the resting behavior of fry exposed to 106 particles/L was observed. Amitriptyline exposure exerted a significant effect on development, caused elevated acetylcholinesterase activity and inhibition of two carboxylesterases. Most obvious was the severely altered swimming and resting behavior. However, effects of amitriptyline were not modulated by microplastics.

Authors: Gao Dedao , Long Aihua , Yu Jiawen , Xu Helian , Su Shoujuan , Zhao Xu
Published: August 2020

Quantitative analysis of the reallocation and linkages of virtual water in the economic sector was important for the integrated water resources management in inland arid regions. Taking the northern Tianshan Mountains (NTM) as an example, we applied the environmental input-output model to design the accounting framework for the reallocation of blue and green virtual water (VW) in the economic sector and analyzed the correlation effect of VW reallocation among various sectors by backward and forward linkages in economic analysis. The results showed that the direct blue and green water consumption of primary industry respectively accounted for 99.2% and 100% of the total water consumption in NTM. Planting sector had the largest amount of VW outflow among all sectors. Animal husbandry, forestry and construction had a large pulling effect on VW outflow of planting sector, while planting sector and animal husbandry were the main sectors for VW export of blue and green water. We suggest that the government can increase the import of blue-green VW for agricultural raw materials through VW trade and develop industries such as service and electricity that have less pulling effect on the primary industry VW, so as to improve the economic added value of VW in the primary industry and reduce the loss of VW in primary industry production and trade flows in future water management.

Pharmacology of inhibitor-protected beta-lactam agents
Authors: Kryukova D. , Sokolov A. , Maksimov Maksim
Published: August 2020

Beta-lactam antibiotics are the most widely used class of antibacterial drugs, both for outpatient and hospital infections. Their further improvement in relation to overcoming the resistance of microorganisms to this group of antibiotics has given new opportunities in the treatment of severe infectious diseases. Due to the obtained high efficiency of β-lactam antibiotics and their low toxicity, they form the basis of antimicrobial chemotherapy at present. Antibiotic resistance is the phenomenon of resistance of a stain of infectious agents to the action of one or more antibacterial drugs. It is a reduced sensitivity (resistance, immunity) of a culture of microorganisms to the action of an antibacterial substance. One of the main mechanisms for the formation of bacterial resistance to them is the production of beta-lactams. To overcome the acquired resistance widespread among microorganisms, compounds have been developed that can irreversibly suppress the activity of these enzymes, the so-called beta-lactam inhibitors - clavulanic acid (clavulanate), sulbactam and tazobactam. They are used to create combined (inhibitor-protected) beta-lactams. Currently, there are several fixed combinations of beta-lactams and beta-lactam inhibitors on the pharmaceutical market. The review article presents the key issues of pharmacology of inhibitor-protected beta-lactam antibacterial drugs.
Pharmacokinetic peculiarities of drugs used in the form of rapidly dispersible tablets (oral delivery system)
Authors: Kozlova Zhanna , Krasnyuk Ivan , Lebedeva Yuliya , Odintsova Ekaterina
Published: August 2020

Oral mucosal drug delivery is an alternative method of systemic delivery with several advantages over both injectable and enteral methods. Drugs that are absorbed through the oral mucosa directly enter the systemic circulation, passing through the gastrointestinal tract and first-pass metabolism in the liver due to oral mucosa being highly vascularised. This results in rapid onset of action for some drugs because of a more comfortable and convenient way of delivery than the intravenous one. But not all drugs can be administered through the oral mucosa due to characteristics of the oral mucosa and physical and chemical properties of the drug.

Published: August 2020

The long-term data from morphometric studies of Artemia males from bisexual and parthenogenetic populations from hyperhaline reservoirs of the Altai region (Bolshoe Yarovoe Lake, Maloe Shklo Lake, and the Tanatar Lakes system) is analyzed in this paper. The description of signs of sexual dimorphism and sexual structure in different populations is given. The influence of brine salinity and hydrogen index on morphometric parameters of males was analyzed. There are differences in the sexual structure of the Artemia population: in the lakes Maloe Shklo and the thanatar system, the populations are bisexual (the share of males is 28.5 — 75.0 %), in the lake Bolshoe yarovoe — parthenogenetic (the share of males on average does not exceed 3 %). At the same time, sexual dimorphism is typical for both types of populations: females are larger than males, males have a larger head (the distance between the eyes is greater by 15.5 %, the diameter of the eye is 26.1 %, the length of the antenna is 22.3 %) and a larger number of bristles (36.1 %). The greatest variability is observed in the parameters of the Furka structure associated with the salinity of water by feedback and the pH — line indicator. Significant differences between the samples of males were revealed. The largest number of significant differences in morphometric indicators was found between samples of males from bisexual populations (lake thanatar and lake Maloe Shklo), the smallest — between males from the parthenogenetic population of lake Bolshoe yarovoe and males from lake Maloe Shklo.

China-Pakistan economic corridor: state and prospects
Authors: Sutyrin S. , Kovalenko V.
Published: August 2020

The article discusses the main aspects of the most important joint project with the people’s Republic of China to create the China-Pakistan economic corridor (CPEC) in the modern history of Pakistan. The transformation of China into an economic superpower, as well as the gradual strengthening of its geopolitical capabilities, has led to the need to form a belt of States loyal to China, ensuring its uninterrupted supply of raw materials, as well as providing Beijing with its transport infrastructure to ensure its unhindered access to the world market. In many ways, Pakistan is an exemplary partner for the middle Kingdom. More than half a century of interaction between the two countries in the political and economic spheres, against the background of the gradual reduction of Pakistan’s dependence on the United States in the 1990s, has led to the fact that the PRC has become a key partner for Islamabad. The implementation of such a large-scale project is not only of great importance for the participating countries, but is also of great interest in the geopolitical context.
Striational Muscle Antibody Positivity Heralding a Diagnosis of Autoimmune Encephalitis associated with Epiglottic Squamous Cell Carcinoma: A Case Report
Authors: Swaminathan Arun
Published: August 2020

A 59 yo woman presented to our emergency room with confusion, spells of loss of awareness over four weeks with malaise, weakness, gait difficulties, and 30 lb weight loss over one year. Brain imaging was unremarkable. EEGs revealed diffuse slowing, triphasic GPDs, and left temporal epilepti form discharges. Spinal fluid showed an elevated protein count. She received a working diagnosis of autoimmune encephalitis and received steroids and antiepileptic medications. She experienced an improvement in symptoms and went home. Follow up revealed elevated striational muscle antibodies and enhancement of spinal nerve roots suggesting an autoimmune neurological syndrome. She received intravenous immune globulin (IVIg) therapy and had periods of improvement followed by worsening a few months later with each dose of IVIg. She presented to the hospital a year with worsening dysphagia and an endoscopy showing an epiglottic mass. Pathology confirmed squamous cell carcinoma, and she received chemotherapy and radiation. We wish to share this rare case of autoimmune encephalitis presenting with only striational antibodies as a heralding sign of a tumor. We postulate that, in the correct context, the presence of striational antibodies alone, despite low titers, may support a diagnosis of autoimmune encephalitis from underlying malignancy.
There are Infinitely Many Fibonacci Primes
Authors: Liu Fengsui
Published: August 2020

We invent a novel algorithm and solve the Fibonacci prime conjecture by an interaction between proof and algorithm. From the entire set of natural numbers successively deleting the residue class 0 mod a prime, we retain this prime and possibly delete another one prime retained, then we invent a recursive sieve method, a modulo algorithm on finite sets of natural numbers, for indices of Fibonacci primes. The sifting process mechanically yields a sequence of sets of natural numbers, which converges to the index set of all Fibonacci primes. The corresponding cardinal sequence is strictly increasing. The algorithm reveals a structure of particular order topology of the index set of all Fibonacci primes, then we readily prove that the index set of all Fibonacci primes is an infinite set based on the existing theory of the structure. Some mysteries of primes are hidden in second order arithmetics.
