A importância da indústria e da industrialização para o desenvolvimento econômico no Brasil: uma revisão bibliográfica preliminar
Authors: Sousa Adriano Amaro de
Published: April 2023

A concentração industrial no Brasil se originou a partir de 1860 a 1880 no Estado de São Paulo, durante o ciclo de expansão das exportações de café que foi o motor primário da acumulação de capital. Nesse sentido, o artigo buscou apresentar uma radiografia do panorama da indústria e da industrialização no Brasil, tendo com eixo condutor a geografia histórica da produção material, através de uma revisão bibliográfica. Todavia, o desenvolvimento do capitalismo brasileiro e da industrialização no período de 1930/80, tem no Estado o fator estimulou a transferência do capital agrário para a indústria através de investimentos em infra-estrutura e políticas econômicas como: organização do mercado financeiro, incentivos que privilegiassem a exportação e a economia industrial – via a fase da industrialização de substituição de importações (ISI). Assim, nos anos 1990, o Estado procurou combater a inflação e controlar a dívida externa para a retomada do crescimento econômico. Entraram em cena as políticas neoliberais: a) abertura da economia ao mercado globalizado; b) desregulamentações dos mercados nacionais balizado pela privatização das empresas públicas e pelas fusões/aquisições de empresas. As empresas nacionais tiveram que aumentar a sua capacidade produtiva e tecnológica devido à competitividade com as empresas estrangeiras chegando sólidas ao século XXI.

Published: April 2023

Este artigo tem como objetivo fomentar o debate acerca da relação centro-periferia no contexto da multi(poli)centralidade da produção capitalista do espaço urbano, com foco em Natal (RN). Especificamente buscamos enunciar a noção de centro, centralidade e periferia, sob a perspectiva lefebvriana; apresentar a leitura de diversos autores sobre a relação centro-periferia na realidade latino-americana, atinente ao espaço brasileiro; e registrar as especificidades de Natal, especialmente nas duas primeiras décadas do século XXI, enquanto recorte espaço-temporal de nossa discussão. Para tanto, realizamos revisão bibliográfica e pesquisa desk-research, como subsídio às discussões e ideias aqui expostas, as quais, preliminarmente, nos levaram à compreensão de que a constituição de novas centralidades e, de fato, novas periferias, não esmaece a relação centro-periferia. Ao contrário e, não contraditoriamente, a reforça.

Published: April 2023

"Dramatic climate changes impose the implementation of new non-polluting technologies to ensure a sustainable development. The textile industry is very polluting, with high energy and water footprints, as well as discharges of toxic emissions and high waste water amounts. Thus, new, less polluting processes have to be brought in to decrease the environmental impact of this industry. Cellulosic fibers play an important role among the raw materials of textile industry. Classical treatments of natural cellulosic fibers use many chemical reagents and a large quantity of water. The progress registered lately in enzymes’ production – regarding their preparation reproducibility and their stability as well – offer a good alternative to chemical reagents. The paper discusses the latest achievements in the application of enzymes for natural cellulosic fibers processing. The state of the art and recommendations for the future are presented."

"Cellulosic plant fibers are good reinforcing materials for composites because they are cheap, light weight, and exhibit good mechanical properties. The isolation of the crystalline portion exposes the stable hydrogen bond network that can form intermolecular bonding with other matrices, such as starch, polyvinyl alcohol and chitosan, among others. Sundried and undried sayote (Sechium edule) vines, of varying degrees of maturity, were subjected to uniform chemomechanical extraction procedures to obtain crystalline fibers. The chemo-mechanically extracted fibers were characterized using differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). DSC thermograms revealed that the sun-dried and mature sample exhibited the narrowest endotherm, indicating the presence of fewer amorphous structures. FTIR spectra showed that the numbers of functional groups present in the fiber samples decreased with increasing degree of maturity. SEM micrographs reveal that the mature portion of the sayote vine had more fibrous and orderly features, compared to the samples extracted from the younger and intermediate portions. Further, chemo-mechanical extraction and X-ray diffraction (XRD) analysis of fibers from mature, sun-dried sayote vines also revealed a relative crystallinity index of the extracted fiber of 65%. The fiber yield from the mature portion of the vine was 9%. Sayote (Sechium edule) vine can be a promising source of crystalline fibers for composite fabrication."

"Sugarcane bagasse (SCB) is a by-product of the sugar industry, with approximately 1.9 billion tonnes produced yearly. The sugar industry produces a huge quantity of bagasse during the manufacture of sugar from sugarcane, which has a negative environmental impact, triggering environmental pollution. In this work, chemically purified cellulose (CPC) and cellulose nanocrystals (CNCs) were very effectively extracted from sugarcane bagasse by the acid-hydrolysis method. The obtained CNCs had a rod-like shape, with a diameter in the range of 2-7 nm, and were used to form a CNC-ZnS nanocomposite. The CNCs were seen to be less agglomerated, and the CNC-ZnS nanocomposite was further tested in an antibacterial study using the agar well diffusion method. The synthesized materials were characterized using a number of analytical techniques. The results demonstrated an enhanced antibacterial property of the CNC-ZnS nanocomposite."

"Polygalacturonic acid, the main structure of demethylated pectin, can be efficiently transformed with hydroxylamine to the corresponding hydroxamic acids in 2-propanol under heterogeneous conditions. The degree of transformation of the carboxylic acid function can be tailored and is significantly larger than when applying a homogeneous procedure. The polygalacturonic hydroxamic acids obtained show good water solubility and are capable of forming gels with Al3+, Fe3+ and Zn2+ ions. The amount of metal ions chelated by the hydroxamic acid derivative for Al3+ and Fe3+ is superior in comparison with the starting material."

"The production of kombucha generates bacterial cellulose (BC) as a by-product, which is usually discarded. However, BC can be a source of cellobiose, a disaccharide with prebiotic benefits. In this study, the yield of cellobiose released from BC collected from a medium-sized kombucha producer was evaluated by enzymatic hydrolysis using the commercial cocktail Celluclast 1.5 L. The BC was hydrolyzed at solid contents of 2, 3 and 4% (m/v), enzyme dosage of 2.2 U/g cellulose, pH 5, 50 °C, and 150 rpm for 72 h. Industrial BC was characterized by FTIR and XRD to confirm the presence of common BC characteristics. The same analyses were performed after enzymatic hydrolysis, resulting in a change in crystallinity. The maximum cellobiose production (10-11 g/L) was obtained with 4% BC (w/v) in 48 h of hydrolysis; there was no significant difference when the time was extended to 72 h. The maximum glucose production under the same conditions was 3 g/L, showing that Celluclast 1.5 L has high cellobiose selectivity (78%). However, the cellobiose yield only ranged from 35 to 26%, indicating that cellobiose accumulation in the medium caused enzyme inhibition."

"Known for its sustainable properties, the usability of hemp instead of conventional cotton hybrid yarns for clothing was investigated by spinning hybrid ring yarns using conventional cotton, viscose-hemp, and organic cotton-viscose-hemp blends for the sheath and elastane and polyester (Lycra and T400) for the core in the yarn structure. Unevenness, yarn imperfections, hairiness, tenacity, and breaking elongation properties of the spun hybrid yarns were examined comparatively by statistical analysis methods. The findings revealed that sheath fiber type, number of components in the yarn structure, and blend ratio were influential factors on yarn quality. Using hemp fiber in the yarn structure slightly decreased the yarn properties, except for tenacity, in general. This situation was more visible in hybrid yarns, which have three different fibers in the sheath. Blending viscose and hemp fibers in the yarn sheath structure provided a synergetic effect, improving the weak properties of both fibers. These yarns had nearly the same tenacity values (from 12.98 to 15.47) as conventional cotton yarns (from 15.24 to 16.8), which could be explained by the fact that hemp fiber has a higher tenacity value (45 cN/tex) than other fibers. Moreover, these yarns had the highest elongation values (from 15.88 to 10.79) due to the good elongation properties of the viscose fibers (20%), compared to other sheath fibers. As a result, when the produced yarns were evaluated in terms of sustainability and performance, viscose-hemp-blended yarns had the optimum yarn properties."

"Biochar (BioC) production from biomass is attractive due to its low cost and relevant physicochemical characteristics. Within this context, the objective of the present work was to produce BioC from cellulose of Pinus elliotti, with different pyrolysis parameters, intended for use in CO2 adsorption from the atmosphere. As main results, the produced BioC presented a porous structure, with a fibrous characteristic, due to the raw material used (cellulose). Also, the biochar prepared at 800 °C (P800) presented higher specific surface area and total pore volume than that prepared at 600 °C (P600), due to the higher pyrolysis temperature applied. On the other hand, P600 presented a higher conversion of cellulose to BioC. Due to these characteristics, P800 presented greater ability to adsorb CO2. Thus, a potential use for BioC was identified in this work."
Ferroelectric properties of triglycine sulfate crystals doped with glycine analogs
Authors: Terasawa Yukana , Ichiki Masaaki , Kikuta Toshio , Asahi Toru
Published: April 2023

Single crystals of ferroelectric triglycine sulfate doped with glycine analogs serine, threonine, lactic acid, and alaninol were grown via the slow solvent evaporation method. The resulting ferroelectric domain structures and polarization–electric field hysteresis loops revealed that these dopants caused triglycine sulfate to form a multidomain structure. This was attributed to hydrogen bonds not being formed, which is significant in polarization reversal, due to the side chains and the substituents of the dopant molecules. Therefore, the dopants did not affect the surrounding dipoles enough to cause cooperative phenomena, such as dipole‒dipole interactions, and do not result in the formation of a single- domain, unlike alanine in our previous study.
Improvement of near-infrared photoelectric conversion efficiency of solution-coated (C8BTBT)(F4TCNQ) films by adding Fe3O4 nanoparticles

Published: April 2023

To realize transparent photoelectric conversion elements useful for optical wireless power-transmission systems and sensors, we investigated thin films of 2,7-dioctyl[1]benzothieno [3,2-b][1]benzothiophene and fluorinated derivatives of 7,7,8,8,-tetracyanoquinodimethane (C8BTBT)(F4TCNQ) produced by a simple solution-coating method. We found that the addition of Fe3O4 nanoparticles (NPs) to a (C8BTBT)(F4TCNQ) solution promoted crystal formation and increased the optical absorption of the film. This was because the addition of NPs formed a middle layer, and the NPs acted as starting points for the formation of crystal nuclei. Photocurrent measurements confirmed that the quantum efficiency (QE) of the film with NPs was improved by about 14-fold compared with the film without NPs. The promotion of crystal formation increased optical absorption and significantly improved QE.

Published: April 2023

Mokymosi sunkumų patiria vis daugiau vaikų. Norint sėkmingai mokytis, svarbu ne tik kokybiška informacija iš aplinkos, bet ir aukšti kognityviniai įgūdžiai. Lavinti nusilpusius įgūdžius buvo sukurta kognityvinių įgūdžių lavinimo metodika BrainRx. JAV atlikti moksliniai ty­rimai parodė puikius šios metodikos rezultatus. Lietu­voje tokių tyrimų dar nebuvo atlikta. Šio tyrimo tiks­las − įvertinti kognityvinių įgūdžių lavinimo metodikos BrainRx efektyvumą 6-15 metų vaikams Lietuvoje. Ti­riamieji, atlikę Gibson testą, pasirinko kognityvinių įgū­džių lavinimo metodą UAB „Golita“ ir UAB „Talentų era“ BrainGym Lietuvos centruose. Vėliau pakartotinai atliko Gibson kognityvinių įgūdžių testą, po kurio buvo surinkti antriniai duomenys. Tiriamųjų duomenys buvo renkami ir apdorojami Excel programoje. Remiantis re­zultatais, vidutiniškai bendras kognityvinių įgūdžių po­kytis sudarė 11,83 proc., 6-10 metų tiriamųjų grupėje šis pokytis sudarė 11,15 proc., o 11-15 metų tiriamųjų grupėje − 14,27 procento. Sudėtinis IQ pakitimas 6-10 metų tiriamųjų grupėje buvo 10,17 proc., 11-15 metų grupėje 11,25 proc., kai bendras grupių pokytis buvo 8,5 procento.

Išvada. BrainRx kognityvinių įgūdžių lavinimo metodi­kos taikymo vaikams bandomojo tyrimo rezultatai pa­rodė teigiamų kognityvinių įgūdžių pokyčių, todėl atei­tyje galima daryti daugiau tyrimų, susijusių su BrainRx kognityvinių įgūdžių lavinimo metodika.

Moterų sveikatos raštingumas yra viena iš aktualių šiuo­laikinės akušerijos temų. Nuolat didėjant nėščiųjų mo­kymo vietoms ir galimybėms, ryškėja aktuali moterų sveikatos raštingumo problema. Moterys mokomos ir informuojamos apie pasiruošimą gimdymui, žindymui, naujagimio priežiūrai, tačiau mokymų, susijusių su mo­terų bendruoju sveikatos raštingumu, atsižvelgiant į jų fizinio aktyvumo, sveikos gyvensenos, mitybos ypaty­bes, Lietuvoje nėra. Moterų sveikatos raštingumas ir jo sąsajos su mityba Lietuvoje nėra aiškiai suprantamos moterims, o sveikatos priežiūros specialistai, pas ku­riuos lankosi nėščiosios, dėl vizito laiko stokos negali jų išsamiai informuoti apie sveikatą ir sveiką gyvenseną nėštumo metu.

Tikslas – išanalizuoti nėščiųjų sveikatos raštingumą ir jo sąsajas su mityba.

Tyrimo medžiaga ir metodai. Atliktas kiekybinis tyrimas anoniminės anketinės apklausos būdu. Tyrimo imtį su­darė 500 moterų. Apklausai naudotas Europos sveikatos raštingumo tyrimo klausimynas (HLS-EU-Q47). Tyrimo duomenys analizuoti remiantis statistine duomenų ana­lize. Tyrime naudojami statistiniai metodai: vidurkis, standartinis nuokrypis, Student t, One-way ANOVA, Re­peated measures ANOVA, Chi-square testas, Pearson arba Spearman koreliacinė analizė.

Rezultatai ir aptarimas. Tyrimas parodė, kad sveikatos raštingumo sritys – ligų prevencija, sveikatos stiprinimas, išskyrus sveikatos priežiūros bei informacijos apdorojimo indeksus (gauti, suprasti, įvertinti, pritaikyti), pateko į pakankamo (puikaus) sveikatos raštingumo kategoriją, apytiksliai 1,5 karto rečiau pateko į per daug svorio nėš­tumo metu priaugusių kategoriją (skirtumai statistiškai reikšmingi, p<0,001; p<0,05; p<0,05). Nustatyta, jog motinos, pagal visus tris sveikatos sričių raštingumo in­deksus ir bendrąjį sveikatos raštingumo indeksą pateku­sios į pakankamo (puikaus) sveikatos raštingumo kate­gorijas, daug rečiau turėjo antsvorio ar buvo nutukusios prieš nėštumą (skirtumai statistiškai reikšmingi: p<0,01, p<0,001, p<0,001, p<0,001).

Išvados. 1.Moterų sveikatos raštingumas susijęs su jų mityba. 2. Respondentės, kurių sveikatos raštingumas (pagal ligų prevencijos ir sveikatos stiprinimo indeksus bei bendrą sveikatos raštingumo indeksą) buvo pakan­kamas (puikus), lyginant su tomis, kurių jis neadekva­tus (probleminis), dažniau pažymėjo, kad valgė daugiau kaip du ar tris kartus per dieną prieš nėštumą (skirtumai statistiškai reikšmingi, p<0,001). 3.Pakankamu (puikiu) sveikatos raštingumu pasižyminčios moterys dažniau nurodė priaugusios nėštumo metu normaliai kūno svo­rio, lyginant su neadekvataus (probleminio) sveikatos raštingumo moterimis.

Smurtas sveikatos priežiūros personalo profesinėje aplin­koje yra visuotinė ir kasdienė problema. Kas trečias dar­buotojas susiduria su pacientų ar klientų smurtu, o jo rizika yra 16 kartų didesnė, palyginti su kitų profesijų atstovais. Smurtas sveikatos priežiūros įstaigose susijęs su neigiamomis pasekmėmis sveikatos priežiūros dar­buotojams ir pacientams.

Tikslas – įvertinti smurto paplitimą sveikatos priežiūros įstaigose.

Metodai. Vadovaudamiesi PRISMA Flow diagramos (1 pav.) gairėmis, 2022 m. lapkričio mėnesį atlikome siste­minę literatūros paiešką PubMed duomenų bazėje pagal paieškos žodžius anglų kalba: workplace violence, vio­lence, workplace issues, bullying, sexual harass, abus; health care workers, healthcare personnel, healthcare staff; risk factors; effects. Atlikus pirminę paiešką, ap­tikta 1 511 straipsnių, iš kurių atrinkti 102. Svarbių pu­blikacijų, tinkamų temos apžvalgai, skaičius sumažintas iki 39. Įtraukimo kriterijai: ne senesni nei 5 metų, anglų kalba, prieinamas visas tekstas.

Rezultatai. Tiriamosios apžvalgos metu išsiaiškintas smurto paplitimas sveikatos priežiūros įstaigose: bendras 59,6 proc., fizinis smurtas 22,4 proc., žodinis smurtas proc., seksualinis priekabiavimas 16,9 procento. Gauti duomenys parodė, kad smurtas sveikatos priežiūros įs­taigose ir jo rūšių paplitimas prieš sveikatos priežiūros darbuotojus yra vienas iš didžiausių, lyginant su kitų profesijų darbuotojais ir turi neigiamos įtakos darbuotojų psichinei ir fizinei savijautai, darbo našumui, kokybei, o kartu ir pacientų sveikatai.

Išvada. Smurtas profesinėje aplinkoje yra dažnas reiš­kinys, o jo rūšių paplitimas prieš sveikatos priežiūros darbuotojus yra gana didelis. Smurtas profesinėje aplin­koje susijęs su neigiamomis sveikatos priežiūros įstaigų darbuotojų fizinėmis, psichologinėmis ir profesinėmis pasekmėmis. Reikėtų imtis priemonių mažinti smurtą profesinėje aplinkoje, ypač sveikatos priežiūros įstaigose.

that of open surgery, few patients have pain till postoperative day 3(up to 72 hours) which can ultimately lead to longer hospital stay, need for rescue
analgesics and other associated complications which nullies the main advantages of laparoscopic surgery. A prospective randomised Methods:
clinical trial was done of 100 patients undergoing laparoscopic surgeries between February 2021 and December 2022 at our hospital. Test group of
50 patients received 0.2 % ropivacaine around port sites and other 50 in the control group received diclofenac injections thrice a day. Pain was
assessed using Visual Analogue Scale. Majority of patients were female(65%), more belonged t Results: o the 26-35 years age group(39%) and
most common surgery performed was laparoscopic cholecystectomy(47%). VAS score at 1hr, 6hrs and 24hrs after surgery was signicantly lower
in test group when compared to control group(p value <0.005) Ropivacaine instillation around port si Conclusion: tes was found to be effective in
reducing post-operative pain signicantly when compared to the control group at 1hr, 6hrs and 24hrs after the surgery

Authors: Vinod Kumar G , Sushma D
Published: April 2023

Introduction: An hereditary form of chronic haemolytic anaemia known as sickle cell disease is accompanied by a variety of acute, painful, and
vaso-occulusive episodes. The main molecular process behind clinical symptoms is polymerisation of hb-s following deoxygenation. The wellknown consequence of prolonged haemolysis is cholelithiasis. Case Report:A33-year-old man with known sickle cell disease came with 15 days
of yellowish discoloration of the mucous membranes, eyes, skin, and skin around the mucous membranes, as well as 10 days of stomach
discomfort. He has been receiving frequent blood transfusions and Tab. hydroxyurea for 25 years. Using an ultrasonogram, cholelithiasis was
identied, and an open cholecystectomy was scheduled. Prior to surgery, the patient began incentive spirometry. To prevent dehydration, he was
kept off of NBM after midnight and put on RLat 100 ml each hour. Athoracic epidural catheter was inserted in the T11-T12 area while under local
anaesthesia since the coagulation prole was normal. Discussion: The clinical hallmarks of SCD, vaso-occlusive phenomena and haemolysis,
cause a variety of signicant organ system problems as well as repeated painful episodes. To avoid acute chest syndrome and atelectasis, extensive
preoperative spirometry was performed. The entire time, enough hydration was kept up. To avoid hypoxia and hypotension, the induction and
intubation processes were carried out with the utmost care. To avoid hypothermia, high, warm intravenous uids were administered, and an
epidural infusion was employed to deliver sufcient analgesia. Conclusion: Successful care of sickle cell disease requires meticulous anaesthetic
control, including preoperative exchange transfusion, avoidance of acidosis, hypoxia, hypothermia, and hypovolemia, as well as maintaining
adequate intraoperative and postoperative pain relief using epidural infusion

Published: April 2023

Introduction Perilunate dislocations and fracture–dislocations are the most common forms of wrist dislocation and encompass a spectrum of
injuries, which can include both ligamentous and osseous disruption. In clinical practice, the prex trans is commonly used to refer to associated
fractures, whereas the prex peri- is used to describe a dislocation. Perilunate fracture–dislocations (greater arc injuries) are more frequently seen
than perilunate dislocations (lesser arc injuries) with the ratio reported to be two to one, with displacement in a dorsal direction in 97% of cases.
Here we present a case of 32 year old male with perilunate fracture dislocation with depressed distal radius fracture, which was managed by open
dorsal approach with proper reduction, k wire xation and good functional outcome

Published: April 2023

Direct laryngoscopy and endotracheal intubation frequently induces a cardiovascular stress response that is characterized by hypertension and
tachycardia due to reex sympathetic simulation and an increase in serum catecholamines. Study was planned to evaluate the safety and efcacy of
esmolol and lidocaine in attenuating the cardiovascular stress responses to laryngoscopy and intubation and to assess whether combination of
drugs is more effective than either drug alone. 90 Patients were randomly assigned by computer based randamozised number into three groups,
esmolol group(group E), lidocaine group(group L) and combination group (group LE).In the operation theatre ,all the patients were secured with
18 G IV line and started on intravenous uids. Standard monitors were attached. Pulse rate, Blood pressure and SpO2 were recorded continuously.
All patients received premedication Inj. Glycopyrolate 0.2mg & Inj. Fentanyl 2mcg/kg. Induction was with Inj. Thiopentone sodium 5mg/kg and
paralysed with Inj. Vecuronium 0.5mg/kg. Group E received normal saline 5ml 3 minutes prior & esmolol 2mg/kg made as 10ml 90 seconds prior
to intubation. Group L received lidocaine 1.5mg/kg made into 5ml 3minutes prior & normal saline 10 ml 90seconds prior to intubation. Group LE
received lidocaine 1mg/kg as 5ml 3minutes prior & esmolol 1mg/kg as 10ml 90 seconds prior to intubation. we can conclude that combination of
esmolol and lidocaine is a safe & effective that can be used in patients undergoing general anaesthesia to attenuate the laryngoscopy responses to
both intubation and extubation , thereby reducing the myocardial oxygen consumption and perioperative risk of myocardial ischemia

Introduction: Six minute walk test (6MWT) is cardiopulmonary exercise which is done for assessing severity of chronic respiratory diseases. The
6 Minute Walking Distance (6MWD) reects the global physiological response to exercise. But this test has certain limitations as it requires space
and more time to perform. In contrast to the 6minute walk test (6MWT), that needs a 100foot corridor to be performed, 2 CHAIR TEST is a quick
and effective exercise test that can be done in a small area. Tota Summary: l 80 participants were included in study, out of which COPD were 48,
asthma 22, Post TB brosis 6, bronchiectasis 2, ILD 2. Among the participants males were more affected than females with the values of 62.5% and
37.5% respectively. The mean age among the participants was 61.68 ± 7.01 years. The comparison between the mean pulse rate of the 6MWT
before and end of the test was done. The mean pulse rate before the 6MWT was 94.73 ± 5.49 beats per minute and at the end it was 107.40 ± 7.56.
The comparison between the mean SpO2 before and end of the 6MWT was 96.20 ± 0.87% and 93.88 ± 0.96% respectively. These results were
statistically signicant. The lap score for the 6MWT was obtained which showed 375.50 ± 49.93 meters as mean. Same tests were done for the 2CT
and the results were signicant. When these tests were compared with the tests of the 6MWT, there was a strong positive correlation between pulse
rate and Spo2 at the end of 6MWT and 2 Chair TEST (2CT) respectively

Published: April 2023

Rheumatoid arthritis (RA) is a chronic systemic illness affecting joints and extra-articular structures and is the most prevalent kind of inammatory
arthritis worldwide. Patients of rheumatoid arthritis have increase risk of cardiovascular disease as compared to general population. Local
inammation of the affected joints, manifesting as joint pain and swelling, generally represents the clinical disease activity in RAand is measured
by various joint indices like Disease Activity Score 28 (DAS 28) and Clinical Disease Activity Index (CDAI). Fibrinogen is the major determinant
of plasma viscosity and it represents link between inammation, thrombosis and cardiovascular risk. The aim was to study the association of
plasma brinogen with Disease activity score in rheumatoid arthritis and to compare levels of plasma brinogen in patients with rheumatoid
arthritis with healthy population. Materials And Methods:This study was a cross sectional study done in 70 subjects ( 35 diagnosed RApatient by
ACR 1987 criteria and 35 healthy subjects) in Assam Medical College and hospital from June 2021- May 2022.The quantitive determination of
plasma brinogen was done using clot detection method. We also measured ESR using Westergren's method. Statistical analysis was done using
SPSS software. Results: The mean value of plasma brinogen was 381.143±43.71 in rheumatoid arthritis versus 314.285±46.29 in controls. This
difference was statistically signicant <0.001.On evaluating brinogen level and DAS28 score, it was noted that patient with higher DAS28 had
signicantly higher brinogen level (p<0.01). Conclusion: This study concluded that plasma brinogen is signicantly elevated in patients with
active rheumatoid arthritis and is signicant with increasing severity of the disease. As brinogen is the risk factor for cardiovascular disease it can
also be added in routine monitoring of disease activity along with other parameters

Goal. Ecotoxicological and economic substantiation of the biological system of apple protection against pests and diseases, its optimization and adaptation to the weather and climatic conditions and the phytosanitary state of apple agrocenosis in the Precarpathian province of the Carpathian mountain zone of Ukraine in order to reduce crop losses and improving its quality.
Methods. Phytosanitary monitoring was performed visually and using pheromone traps. The degree of hazard of pesticides was assessed by an integrated 7-point scale, the risk — by agroecotoxicological index (AETI).
Results. Based on the monitoring of the phytosanitary state of the apple agrocenosis in 2015—2017, scientific and methodological parameters of ecologically safe and cost-effective protection systems for apple trees adapted to the soil and climatic conditions of the Precarpathian province of the Carpathian mountain zone of Ukraine were developed: biological and biological-chemical. They are based on 7 treatments with biological or chemical and biological preparations, carried out in the phenophases of culture critical for the development of harmful organisms. The efficiency of the biological system against harmful organisms was in the range of 65.7—72.8%, the biological-chemical system — 66.4—96.5%. It is shown that replacing a number of chemical treatments with biological ones allows to minimize the negative impact of pesticides on the apple agrocenosis.
Conclusions. A model of ecologically safe protection of an apple orchard against a complex of harmful organisms has been developed. It is shown that the modern assortment of biological protection means makes it possible to develop a system that provides effective protection of the apple orchard against a complex of diseases and pests. Calculations showed that the system of biological and chemical protection was more effective in terms of profitability during the years of research (71.4—127.23%). The profit obtained from the use of this system was from 49 898.9 to 107 586.4 UAH/ha.

Methyl bromide fumigation aims to control insect infestation in mangosteen fruit before export which leads to reduce the fruit quality. Thus, the objective of this study was to control the quality of methyl bromide fumigated mangosteen using integrated postharvest technology. Fruit were prepared by fumigating with 32 g m-3 for 2 hours, washed with tap water, surfaced disinfestation with sodium hypochlorite. The prepared fruit samples were divided to treat with different methods as follows; 1) fruit were coated with ethanolic shellac-modified coconut oil (ES-MCO) and then packed in low density polyethylene (LDPE) bag containing ethylene inhibitor (1-MCP sachet), 2) fruit were coated with ES-MCO and packed in LDPE bag, 3) fruit were treated with ES-MCO and packed in nylon net bag, and 4) fruit were non-coated and packed in nylon net bag (control). All fruit samples were kept at 13ºC for 20 days (as the shipment stimulation) and then transferred to 25ºC for 2 days (as the shelf-life stimulation). The results revealed that after 15 days of storage fruit were treated with ES-MCO + LDPE bag + 1-MCP sachet showed the highest reduction of fruit rot disease and this treatment helped to delay the drying and browning of mangosteen calyx, chlorophyll degradation of the calyx, and reduce weight loss, the respiration rate and ethylene production. However after storage for 20 days, the pericarp of mangosteen in fruit treated with ES-MCO + LDPE bag + 1-MCP sachet became hard, and its shelf-life was 15 days.
