ASSESMENT OF SEXUAL AND REPRODUCTIVE CORRELATION IN THE SEASONAL DYNAMICS OF THE AGROTIS SEGETUM POPULATION AT IMAGO STAGE

TUDOR NASTAS, IULIANA RUSU

During seasonal activity A. Segetum has been shown to evolve over three generations. The development of the first generation was noted during the first decade of May and the second decade of June. The development of the second and third generations was established between the first decade of July and the second decade of September. The assessment of the sexual correlation of imago Agrotis segetum during crop growing, showed the ratio of males to females is 1,3 : 0,8. The Agrotis segetum phytophagus has been shown that the present climate of the Republic of Moldova, increased aggressiveness on crops, and the number of eggs in the egg tubes of the females does not depend on the number of copulatory acts (estimated by the number of spermatophores in the copulatory bags of females). Analysis of the females showed that the copulative bags contained between 1 and 6 sperm, which means that they were paired with the males up to six times. Females with 2 pairs (30%) and 3 pairs (23%), representing 53% of the total number of captured females.

This paper aims to implement and understand the mechanisms by which cervical lesions intervene in the pathogenesis of lesions precursor to neoplasia, as well as knowledge of their cytological investigation methods. The study is channeled towards a complete evaluation of the complex diagnosis of cervical intraepithelial lesions, based on classical methods of investigation that include the Babeş-Papanicolaou cytological examination. The cervix can be easily examined cytologically. The use of this method of investigation leads to the discovery of the disease in the early stages, 100% curable (Koss, 1989). The observations were made on cervico-vaginal smears. The vaginal secretion product was collected from 282 patients examined in the obstetrics-gynecology office "Clinic Center Hera" Bacau, for one year, March 2019 - March 2020. The samples were processed and clinically examined in the Medlife laboratory, Bacau . The working method used was Papanicolau in liquid medium, May-Grünwald-Giemsa staining, Papanicolau classification. Following the study, 73.85% of patients were identified with PN I and II smears, 8.83% were patients with PN III smears and 6.36% were patients with PN IV. Most cytological changes in the cervix occur in sexually active women over the age of 35.

CĂTĂLIN IONEL CIONTU(1), LUCIAN DINCĂ(2)

The surface of game funds from Harghita County amounts to 593.944 ha gathered in 45 funds. They are characterized by a moderately continental climate in Sub-Carpathian hills and a mountain climate in the high areas. Eight species were selected among the county’s main game and fish species, namely bear, fox, capercaillie pine marten, magpie, hooded crow, trout and grayling. The species were classified based on their results from 19 criteria (harvesting period, harvested quantity by one worker in eight hours, harvesting cost, harvesting knowledge, required instruments, the harvesting process’s complexity, distribution array, biotic threats, abiotic threats, perishability, market potential, market request, the product’s market “popularity”, raw product price, derived product price, derived products portfolio, transport from the harvesting place to the storage center). Grades from 1 to 8 were given to each analyzed species by specialists. As such, the most important species are the trout and, grayling while the species with the smallest percentage were hooded crow and magpie. The species’ harvesting and distribution potential as well as their diversity in the county are high as both the forest and fish areas are very well represented. In this way, the game and fish species with a high interest have the space and environment in which to reproduce and develop.

This paper, which proposed a study on methicillin-resistant Staphylococcus aureus (MRSA) infection, is based on analyzes and statistical processing that were performed between July 2019 and March 2020. A retrospective descriptive study was performed in the laboratory of SC medical analysis. HYRON ARS MEDICA S.R.L. from Bacău. The following data were taken from the records made in the Rilab software: name and surname, age, type of analysis requested and also information on pre-existing conditions and treatments recommended by the doctor were taken. The study was performed in patients who were explained the purpose and protocol of the study and who gave their consent to participate. The study group included 1304 patients. Of these, 320 patients were infected with Staphylococcus spp., Aged between 1 month and 83 years, of which 285 patients were under 20 years of age at the time of the study. There has been a significant increase in the percentage of patients in whom Staphylococcus aureus manages to enter, infect and spread in the body, despite the body's own defense mechanisms. An important role in this regard is played by nosocomial infections, which are among the main risk factors in terms of the share of infections.

The side effects of pesticides have been constantly studied, and are the subject of books such as the one written by biologist and journalist Rachel Carson who talked about the negative effects of DDT (Dichlor-Diphenyl-Trichloroethane) on the environment in the book "Silent Spring" (Rachel Carson, 1962), a book that would destroy the fame of DDT. Due to undesirable side effects in 1970, DDT was banned in industrialized countries and since 2004 the "Stockholm Convention" has banned its use in agriculture. The human attitude towards pesticides has two aspects: the protection of consumers against pesticide residues in food and the training of those who produce or handle pesticides in the sense of proper use. Whether it is insecticides, fungicides, or herbicides, we must keep in mind that the dose is what makes the poison. The objective of this paper is to test glyphosate in two groups of test organisms, according to the recommendations of the OECD-Organization for Economic Cooperation and Development, respectively on Folsomia candida- (OECD 232) and wheat- (OECD 208). The results obtained after laboratory testing have revealed the harmful effect of this herbicide on wheat at high concentrations (of 5mL/0.25mL water, respectively 7.5mL/0.25mL water), inhibiting the seed germination process as well as the plant growth processesand development and their content in assimilating pigments. Although the mortality rate for adults of F. candida was low, the number of juveniles decreased in direct proportion to the concentration of glyphosate used in the experiment.

STUDY ON THE INCIDENCE OF ANTI-SARS COV2 ANTIBODIES TO HEALTHCARE STAFF

TATIANA CIUREA(1), DANIELA TITA(2), DIANA IOANA TITA(3)

The exact extent to which a person with SARS CoV2 infection can transmit the infection to other is uncertain. The potential for SARS-CoV-2 transmission begins before the onset of symptoms and decreases thereafter. Infected people are more likely to be contagious in the early stages of the disease, when the level of viral RNA in the upper respiratory tract is highest. The duration of viral RNA clearance is variable and may increase with disease severity. In some people, viral RNA can be detected in the respiratory tract a few months after the initial infection. However, detectable viral RNA does not always indicate the presence of the infectious virus and there appears to be a threshold below which the infectivity is unlikely. Prevention and limitation measures are essential in both healthcare and the community. Medical personnel must apply additional precautions to protect themselves and prevent the transmission of the disease during medical care. This paper aims to study the incidence of the IgM and IgG antibodies anti-SARS CoV2 in healthcare professionals. The determination of antibodies was made on request, both to see the immunization of people who went through the disease and to evaluate asymptomatic personnel (they came in direct contact with confirmed people).

The paper aims to highlight the value of laboratory investigations in various pleurisy by exploring the pleural fluid on the three levels (biochemical, bacteriological and cytological), correlating it with the clinical and imaging aspect to establish the etiology of pleurisy. The researches were performed in the Clinical Laboratory within the Bacău Pneumoftiziology Hospital between March and May 2020. To study the characteristics of pleural fluids, a number of 56 subjects diagnosed with pleurisy of different etiologies were analyzed. Laboratory tests were performed on pleural fluid obtained by pleural puncture. The patients investigated were grouped by sex, according to background and age groups. The investigation of pleural fluids on the three levels (biochemical, cytological and bacteriological), correlated with clinical manifestations and radiological aspects led to the diagnosis of patients with the following types of pleurisy: tuberculous pleurisy, parapneumonic, neoplastic, eosinophils and pleurisy due to other causes. In all types of pleurisy, male patients have the highest number of cases. All neoplastic pleurisy was recorded in age group III.

The genus Artemia, known as the brine shrimp, represents an important inhabitant of hypersaline lakes of Romania. Worldwide, the genus consists of six well-characterized bisexual species and several clonal lineages described with the binomen Artemia parthenogenetica. Despite its conspicuous appearance and numerous records in the literature, dating back to the eighteenth century, no positive identification can be provided for Artemia in Romania: the citations change from Artemia salina, to Artemia sp, Artemiaparthenogenetica, or parthenogenetic strains of Artemia. The present paper represents a review of previous records of the genus in Romania. Further studies are mandatory to clarify all taxonomic issues associated with this genus.

TATIANA CIUREA(1), DANIELA TIŢĂ(2), IONUŢ STOICA(3)

Lamotrigine is a broad-spectrum antiepileptic used as monotherapy or as an adjunct to other antiepileptics for the treatment of partial or generalized tonico-clonic seizures. This drug is also used in the treatment of neurological lesions, bipolar disorder, and other psychiatric disorders. The choice of the appropriate method for the routine monitoring of the drug administered to the patient with epilepsy in order to individualize the therapy, the difficulty of establishing the dose, the therapeutic field, the fluctuations of the serum concentration in certain physiological conditions (during pregnancy) imposed this study. The literature presents several methods for determining LMT and metabolites in the biological matrix including: HPLC, gas chromatography with nitrogen-phosphorus detector, mass spectrometry with thermospray chromatography, capillary electrophoresis, radioimmunoassay, immunofluorimetric analysis, UV electrophotometry, methods. In this paper, the focus was on chromatographic and spectrophotometric and electrochemical methods. Electrochemical methods with modified electrodes for LMT dosing are gaining ground lately. The choice of method aims at: simplicity of analysis, precision, accuracy, sensitivity and selectivity of the method, low analysis time, low costs.
