PHOTOSYNTHESIS OF VEGETABLES AND FIELD PLANTS IN RESPONSE TO BIOCHAR TREATMENT

The requirements of modern agriculture include besides obtaining maximum yields of crops also maintaining and improving soil fertility and environmental protection. In recent years, interest of usage solid phase (charcoal or biochar) obtained by pyrolysis as soil improver, increases. Biochar is a solid material obtained from the thermo chemical conversion of biomass in anoxygen-limited environment. Additions of biochar to soil have generally been shown to be beneficial for growing crops. From an agronomic perspective it is suggested that biochar could improve soil health by increasing nutrient retention. The present pot experiment was conducted to investigate the effect of biochar application on the plants photosynthetic activity. The experiment was carrying out on two soil types, treated with different BC ratio. The plants grown on cinnamic pseudopozolic soil show a high content of plastid pigments in comparison with these on alluvial meadow soil. The aim of study is to evaluate the biochar agronomic impact on the plants growth, development and quality indicators

Phytoconstituents and bioactivity of plants of the genus Spiraea L. (Rosaceae): A review

The genus Spiraea L. belongs to the Rosaceae Juss. family and includes more than 100 species distributed in the temperate zone and subtropical zone of the Northern Hemisphere at the center of species diversity in East Asia. Representatives of the genus are known as ornamental plants with many forms and varieties, are widely used in conventional medicine, and have a high resource potential. This review provides information on the diversity of phenolic compounds (flavonoids, phenolcarboxylic acids, and lignans), terpenoids, alkaloids, steroids, and other classes of secondary metabolites in the species of Spiraea worldwide. The article also presents little-known and hard-to-find data published in Russian concerning Spiraea phytochemistry. The biological activities of extracts and their fractions and of individual compounds having different types of biological activity (e.g., antioxidant, antibacterial, anti-inflammatory, and antifungal) are discussed. Data about biotechnological research on representatives of the genus Spiraea are presented too. The analysis of the literature showed that further chemical and pharmacological studies on Spiraea plants are quite promising

Caesarean section in a semi-rural hospital in Northern Namibia

BACKGROUND: Increasing caesarean sections rates (CSR) are a major public health concern and the prevention of the first caesarean section, which often leads to repeat operations, is an important issue. Analyzing caesarean sections can help to identify factors associated with variations in CSR and help to assess the quality of clinical care. METHODS: In a retrospective observational study, during a two year period, indications of 576 caesarean sections were analyzed using intra-operative internal pelvimetry and a record keeping system in a semi-rural hospital in Northern Namibia. RESULTS: Most caesarean sections were done for dystocia (34%) followed by repeat caesarean section (31%). The true conjugate (distance between the promontorium to mid pubic bone) was significantly smaller in these recurrent indication groups when compared to non recurrent indications. CONCLUSION: In this rural hospital the introduction of Delee Pelvimetry and a caesarean section record keeping system was found to be a simple and cheap method to analyse indications for caesarean sections, which may help in reducing unnecessary caesarean sections

Cross-border media and nationalism: Evidence from Serbian radio in Croatia

How do nationalistic media affect animosity between ethnic groups? We consider one of Europe’s deadliest conflicts since WWII: the Serbo-Croatian conflict. We show that, after a decade of peace, cross-border nationalistic Serbian radio triggers ethnic hatred towards Serbs in Croatia. Mostly attracted by non-political content, many Croats listen to Serbian public radio (intended for Serbs in Serbia) whenever signal is available. As a result, the vote for extreme nationalist parties is higher, and ethnically offensive graffiti are more common, in Croatian villages with Serbian radio reception. A laboratory experiment confirms that Serbian radio exposure causes anti-Serbian sentiment among Croats.

Features of management of atopic dermatitis in pregnant women

Atopic dermatitis (AD) is a chronic allergic skin disease, the most common of dermatoses during pregnancy. Exacerbation of AD can be at any stage of pregnancy, its main causes are an increase in progesterone levels, the predominance of Th2 cytokines, psychoemotional stress, violations of the gastrointestinal tract. Changes occur in the clinical picture, the lesions on the face and extensor surfaces of the extremities, papules. Treatment options for pregnant women are limited due to the unethical nature of clinical trials. It is safe to use topical glucocorticosteroids, moisturizers, narrow-band UVB 311 nm, calcineurin inhibitors are relatively safe. In systemic therapy in severe cases, the use of cyclosporine or a short course of prednisone is recommended. There is no evidence of the safety of selective immunosuppressants

Investigation of chemical constituents of Eranthis longistipitata (Ranunculaceae): coumarins and furochromones

Aqueous‐ethanol extracts (70%) from the leaves of Eranthis longistipitata Regel. (Ranunculaceae Juss.)—collected from natural populations of Kyrgyzstan—were studied by liquid chromatography with high‐resolution mass spectrometry (LC‐HRMS). There was no variation of the metabolic profiles among plants that were collected from different populations. More than 160 compounds were found in the leaves, of which 72 were identified to the class level and 58 to the individual‐ compound level. The class of flavonoids proved to be the most widely represented (19 compounds), including six aglycones [quercetin, kaempferol, aromadendrin, 6‐methoxytaxifolin, phloretin, and (+)‐catechin] and mono‐ and diglycosides (the other 13 compounds). In the analyzed samples of E. longistipitata, 14 fatty acid–related compounds were identified, but coumarins and furochromones that were found in E. longistipitata were the most interesting result; furochromones khelloside, khellin, visnagin, and cimifugin were found in E. longistipitata for the first time. Coumarins 5,7‐dihydroxy‐4‐methylcoumarin, scoparone, fraxetin, and luvangetin and furochromones methoxsalen, 5‐O‐methylvisammioside, and visamminol‐3′‐O‐glucoside were detected for the first time in the genus Eranthis Salisb. For all the above compounds, the structural formulas are given. Furthermore, detailed information (with structural formulas) is provided on the diversity of chromones and furochromones in other representatives of Eranthis. The presence of chromones in plants of the genus Eranthis confirms its closeness to the genus Actaea L. because chromones are synthesized by normal physiological processes only in these members of the Ranunculaceae family

naklada - Zagreb, Croatia USE OF THE COMMUNICATION CHECKLIST - SELF REPORT (CC-SR) IN SCHIZOPHRENIA: LANGUAGE IMPAIRMENTS CORRELATE WITH POOR PREMORBID SOCIAL ADJUSTMENT

Background: The present study reports preliminary results from the multicentre project on the approbation of the Russian language version of the “The Communication Checklist-Self Report” (RL-CC-SR) and its first use in schizophrenia (SZ), aiming to evaluate the contribution of language disturbances in the pathogenesis of this heterogeneous disorder. Subjects and methods: The study evaluated patients’ clinical state with the Diagnostic Interview for Psychoses (DIP), and assessed language and communication disturbances (LCD) with the RL-CC-SR in all participants (213 healthy controls (HC), 83 SZ patients, 31 SZ first-degree relatives). Data from the current sample of SZ (n=50), and HC (n=213) was analysed to calculate the relationships between LCD, social and clinical variables using descriptive statistics methods, T-test and Pearson’s correlations (SPSS-26, 2019). Results: The quotient scores (<6) and raw scores on all three CC-SR subscales demonstrated prominent LCD in SZ: (i) language structure (LS) (SZ:11.92±8.01, HC:7.54±5.91; <0.001), (ii) pragmatic skills (PS) (SZ:11.30±10.07, HC:8.71±7.39; =0.040), (iii) social engagement (SE) (SZ:31.94±11.76, HC:19.42±10.35; <0.001). In SZ, Pearson correlations of LS scores were significant for the DIP-items Odd Speech (p=0.033), and Social Engagement - Blunted Affect (p=0.042). PS was related to early disease onset (=0.027), poor premorbid work adjustment (p=0.003), along with LS (p=0.005), and was also linked to poor premorbid social adjustment (p=0.005). Conclusions: SZ patients are aware of their LCD at all levels of language structure, pragmatics, and nonverbal communication, but are unable to compensate. Disturbances of LS and PS in SZ patients relate to their poor social adjustment and functioning, and may prove to be associated with the primary negative symptoms domain of the disorder and its generally poor outcome
