DETERMINANTS OF GREEN PRODUCT EXPORTS IN VIETNAM: DO IMPORTERS’ CHARACTERISTICS MATTER?
Authors: Nguyen Thi Thu Huong  , Phan Thi Bich Ngoc
Published: February 2025

This study examines the factors influencing Vietnam’s green product exports, with a particular emphasis on the characteristics of itstrading partners. Adopting the Poisson pseudomaximum likelihood estimations for a gravity model, the study analyzes bilateral green exports from Vietnam to 169 partners from 2002 to 2022. The empirical evidence demonstrates that exchange rate fluctuations and geographical distance hinder exports, whereas free trade agreements and historical dependencies foster exports. Additionally, the study reveals that GDP per capita, population, human development, tax burden, and financial freedom among importing countries are key factors in promoting Vietnam’s green exports. The results imply that promoting Vietnam’s green exports requires stable exchangerates and active engagement in free trade agreements. In addition, Vietnamese exporting firms seeking to increase green exports should target countries with high GDP per capita, significant economic size, advanced human development, heavy tax burden, and well-liberalized financial systems, as well as those with a shared history of interdependence with Vietnam.

GRAIN SIZE-MOLAR RATIO EFFECTS ON MAGNETO-ELECTRIC PROPERTIES IN PB(ZR0.52TI0.48)O3/COFE2O4 PARTICULATE MULTIFERROIC COMPOSITES BY MICROWAVE OVEN SINTERING
Authors: Parra-Jimenez K. R. C. , De La Espriella Nicolás
Published: February 2025

This study aims to investigate the electric, magnetic, and magnetoelectric properties for the lead zirconate titanate-cobalt ferrite particulate multiferroic composite, Pb(Zr0.52Ti0.48)O3/CoFe2O4.The composites were synthesized utilizing the Pechini method and thermally sintered employing a microwave oven and a conventional method. Two molar ratios, 80/20 and 50/50, of the constituents' phases were utilized to analyze the effect of grain size on properties. The results of X-ray diffraction (XRD) patterns indicated no formation of secondary phases for powder phases and ceramic composites. The micrographs exhibited the distribution of magnetic grains in the ferroelectric matrix and displayed 0-3 connectivity. The dielectric constants, electric resistivity, and ferroelectric properties demonstrated a decrease in their values between approximately 10% and 20% for composites sintered by the microwave-oven method, which was attributed to the decrease in the grain size of the ferroelectric phase and the molar increase of the magnetic phase, resulting in electrical losses due to the presence of a non-ferroelectric phase. The magnetic hysteresis and magnetostriction coefficients exhibited higher values for the microwave-oven method than the conventional method as the magnetic anisotropy effect is more pronounced for smaller ferrite grain sizes. The induced voltage via magnetoelectric coupling was observed for all composites. The composites produced by microwave sintering (MS) exhibited higher voltage values than those produced by conventional sintering (CS). However, the magnetoelectric coefficients for composites with a 50/50 molar ratio were lower than those with an 80/20 molar ratio, which was potentially attributed to the reduction in ferroelectric grain size and increased electrical losses. Consequently, these results demonstrate a novel approach to improve performance and potential applications for functional devices.

Plant extracts in poultry production are widely recognized for their significant benefits in improving productive performance. Specifically, the in ovo administration of soursop leaf extract (SLE) shows promise in improving the health and productivity of Noiler chickens. This study aimed to provide valuable insights into the health of the chicks and evaluate the effectiveness and safety of in ovo SLE in poultry production by examining the blood profile, internal organs, and intestinal morphology of Noiler chickens. For this experiment, 640 hatching eggs were incubated and randomly divided into four experimental groups, including 0.25 µg SLE, 0.5 µg SLE, 0.75 µg SLE, and a non-injected control group. Three treatment groups received a direct injection of 0.2 ml of the respective SLE concentrations into the air cells of the eggs on the 18th day of incubation. After hatching, chickens from each group were divided into five replicates of 15 chicks each and raised using a completely randomized design. At ten days of age, blood samples were collected from two chicks per replicate for hematology and serum analysis. Two chicks per replicate were sacrificed on day 10 to assess the internal organs and intestinal morphology. The results showed no significant changes in hematological parameters, serum biochemistry, and internal organs in all groups. The soursop leaf extract groups had markedly longer villi, deeper crypts, and thicker muscular walls compared to the control group. In conclusion, the in ovo injection of soursop leaf extract at 0.75 µg improved intestinal health by enhancing the intestinal surface structures in Noiler chickens.

Eimeria species cause coccidiosis, a poultry disease that occurs worldwide. Infection is linked to decreased feed efficiency and body weight increase. The present study aimed to assess the prevalence of coccidian species in Togolese poultry farms and evaluate the anticoccidial efficacy of three local medicinal plants. From July to September 2023, two hundred and ninety-five fecal samples were randomly collected using a cross-sectional observational study in the maritime region of Togo, specifically in Vo, Lacs, Zio, and Grand-Lomé districts. Data on risk factors were collected through an interview with the poultry farmers. All fecal samples collected were subjected to Eimeria oocyst counting using the standard McMaster technique. The anticoccidial activity of the extract of Azadirachta indica leaves Carica papaya seeds, and Sarcocephalus latifolius roots in a completely randomized design was evaluated on 23-day-old male Isa brown chicks infected with 30.104 oocysts. Body weight gain, feed efficiency, lesion score, proportion of bloody droppings, anticoccidial index, and excretion of coccidia oocysts were assessed. The results revealed an overall prevalence of 39.66% (117/295) for coccidiosis, with 75% of positive samples having fewer than 10,000 oocysts/g. The logistic regression test indicated that the interval between two anticoccidial prophylaxis applications, age, management, and breed were significant risk factors associated with coccidial infection, with young chicks (≤ 8 weeks) being 5.66 times more susceptible than those older ones (8 weeks) with 0.86 as an odd ratio. Six Eimeria species were identified, with E. maxima (54.17%), E. brunetti (33.33%), and E. tenella (25%) being the most common. The anticoccidial efficacy of Azadirachta indica leaves, Carica papaya seeds Sarcocephalus latifolius roots extract, and amprolium was demonstrated by a reduction in lesion scores, bloody diarrhea, and oocysts per gram in feces (OPG) as well as an improvement in body weight, feed conversion ratio, and production efficiency factor when compared to infected and untreated groups. The anticoccidial index was marked in the chickens treated with Sarcocephalus latifolius roots extract (170) and amprolium (176). The findings of this large-scale epidemiological study and anticoccidial efficacy tests revealed that these Togolese medicinal plants can be sustainable and cost-effective strategies for coccidiosis control.

Published: February 2025

Catfish offal flour (COF; Pangaius hypopthalmus) has the potential to replace fish meal (FM) due to its high crude protein content. The present study aimed to investigate the effects of substituting FM with COF in basal diets on food intake (FI), body weight gain (BWG), and feed conversion ratio (FCR) in quails. A total of 100 male quails were randomly assigned to five treatment groups, each with four replicates. The treatment groups were fed with basal diet + 0% COF and 100% FM (T0), basal diet + 25% COF and 75% FM (T1), basal diet + 50% COF and 50% FM (T2), basal diet + 75% COF and 25% FM (T3), and basal diet + 100% COF and 0% FM (T4). Feed intake, BWG, and FCR were measured from 0 to 35 days of age. The findings indicated that substituting FM with COF up to 100% did not significantly affect FI, BWG, and FCR. It can be concluded that COF has the potential to replace FM in basal diets while maintaining performance in quails.

Oxygen concentration (O₂) during incubation is crucial for embryo development, and hypoxic conditions can influence phenotypic plasticity in poultry. Although low O2 (hypoxia) can be detrimental, it may also promote adaptive responses. Breeder age, a known genetic determinant of egg quality and embryonic development, is likely to interact with O₂ levels during incubation, however, this relationship remains understudied in layer breeders. This study examined how layer breeder age and reduced oxygen (O₂) levels during early embryonic development affect various factors, including eggshell decalcification (Dcal-SHL), chorioallantoic membrane (CAM) weight, heart tissue vascularization, egg weight loss (EWL), eggshell temperature (EST), and calcium (Ca) and phosphorus (P) content in bone and blood and tibia and femur morphometrics. A total of 900 eggs from 33 and 50-week-old ISA brown layer breeders were incubated in a 2x3 factorial design with O₂ levels of 15%, 17% (hypoxic), and 21% (control). Oxygen was reduced for 1hr/day from embryonic days (ED) 7-9 using air-N₂ flushing. Results showed increased CAM weight and heart tissue vascularization under hypoxia, especially in older breeders (50 weeks). Hypoxic conditions (15% and 17% O₂) reduced embryo weight loss and eggshell temperature compared to controls during the post-exposure phase (ED 15-18). There was an interaction between breeder age and O₂ levels on mineral absorption, with reduced oxygen leading to lower Ca and P absorption in bones, higher eggshell P retention, and decreased tibia morphometrics (weight, length, diameter, and seedor index) in hatchlings. Additionally, CAM weight correlated negatively with Dcal-SHL Ca at 15% O₂. The study concluded that reduced oxygen during early embryonic development increases CAM weight, heart neovascularization, and Ca mobilization from eggshell to blood. However, older flocks exhibited reduced Ca transfer to bones, likely due to homeostatic imbalance.
Virus Defektif Hepatitis D Satelit Subviral Hepatitis B

Published: February 2025

AbstrackHepatitis delta virus (HDV) was isolated from liver biopsy of a person with chronic HBs Ag. HBV virions and virions with delta antigen are pathogenic and very infectious. HDV is considered as a subviral satellite because of their distribution in hepatocyte cells only in the presence of HBV. Deltavirus is an incomplete RNA virus (defevtive virus), because HDV can not cause infection, for the occurrence of an HDV infection of HBV infection should occur before or at the time together. HDV genome is a circular singel-stranded RNA of negative polarity, consisting of 1700 nucleotides and did not reveal any homology with HBV genome. Spherical-shaped virion particle size 36 nm is a component of the outer, diencapsidasi by HBsAg (the envelope) and the inside of the nukeokapsid consists of 60 copies of genomic delta antigen (Dane particles). clinical manifestations of infection depends on the virulence of HBV HDV. On a carrier of HBV infection, who had superinfection, HDV does not depend on the manifestation of HBV. Modes of transmission similar to HBV, infection most often is the intravenous drug abusers. The prevalence of HDV is not always a picture of the prevalence of HBV. In Indonesia,73 reported hepatitis B carriers who donate blood anti-HDV positive 2.7%. Prevention of infection is the prevention of HBV infection, it also indirectly prevent the transmission of HDV. Precautions are taken with HBsAg vaccination.Key word : HDV, Defective virus, Dane particle
Kiat Menjinakkan Sel Kanker

AbstrackCancer lies dormant in all of us. Like all living organisms, our bodies are making defective cells all the time. Thatâ€™s how tumours are born. But our bodies are also equipped with a number of mechanisms that detect and keep such cells in check. People whose immune system is particularly active seem to be protected against cancer cells. Micro-tumours also cannot change into dangerous cancers without creating a new network of blood vessels to feed them. Today many drugs similar to angiostatin are being developed by the pharmaceutical industry. But their effects on humans when used alone have turned out to be disappointing. As an alternative, there are natural approaches that have a powerful effect on angiogenesis, without side effects, including common edible mushrooms, certain green teas, spices and herbs. As a conclusion, proper diet, peaceful mind and exercise are approaches that reinforcing the bodyâ€™s defence mechanisms to keep the cancer at bay.Key words : cancer cells, angiogenesis, natural approaches
Anesthesia Management of Patients with Mental Retardation
Authors: Cegin Muhammed Bilal , Yuzkat Nureddin
Published: February 2025

Mental retardation is a condition likely to develop secondarily to several genetic diseases or to some negative conditions and diseases that occur before, during or after birth. Anaesthetic practices start with the preoperative visit of a patient and are then followed by premedication, preoperative preparation, intraoperative procedures and postoperative periods. All these steps with mentally retarded patients involve separate characteristics. The MR patients must be kept under observation in the recovery rooms for longer periods of time and must also be definitely re-evaluated by an experienced anaesthetist before being transferred to the service department. Since there may be several challenges/difficulties likely to be experienced at each stage of the mentally retarded patients’ anaesthesia, far more care and patience is required. A pre-anaesthetic evaluation involving a physical examination in depth and a detailed questioning should be performed. During the pre-medication period, a little amount of midazolam mixed with a proper drink can be used. Prior to applying the neuromuscle blocking agents, the airway opening must be maintained. In the presence of muscular dystrophies, the doses of neuromuscular blocking agents must be equalized. The MR patients must be kept under observation in the recovery rooms for longer periods of time and must also be definitely re-evaluated by an experienced anaesthetist before being transferred to the service department.

Objectives: The aim of this study is to reveal the effect of ezetimibe monotherapy on plasma viscosity and fibrinogen levels in hyperlipidemia.
Material and Methods: A study group of 31 hyperlipidemic patients was treated for twelve weeks with a monotherapy of ezetimibe 10 mg/day. A healthy control group of 31 individuals with normal plasma lipid profile was also  admitted to the study. PV, fibrinogen and fasting lipid parameters were evaluated. PV was measured by Harkness Capillary Viscometer.
Results: PV and fibrinogen levels decreased significantly with ezetimibe monotherapy (p<0.01). Total cholesterol and low density lipoprotein (LDL) levels were statistically significantly lower than ezetimibe monotherapy group (p<0.001), whereas high density lipoprotein (HDL) level was significantly higher than ezetimibe monotherapy group (p<0.01). HDL level increased significantly in ezetimibe monotherapy group (p<0.01). PV and fibrinogen levels of the control group were lower than ezetimibe monotherapy group before treatment (p<0.01 and p<0.001; respectively). Besides, fibrinogen level of control group was significantly lower than ezetimibe monotherapy group after treatment (p<0.01). Total cholesterol and LDL levels of control group was lower than ezetimibe monotherapy group before and after treatment (p<0.001 and p<0.01; p<0.001, respectively). HDL level of  control group was significantly higher than ezetimibe monotherapy group before treatment (p<0.01).
Conclusions: Ezetimibe monotherapy ameliorates lipid profile and PV parameters in hyperlipidemic individuals. Increased PV and deteriorations in lipid profile may induce endothelial damage in cardiovascular diseases. Being a biophysical mechanical marker, PV may be useful for diagnosis, treatment and follow-up of hyperlipidemic patients treated with ezetimibe monotherapy.
