Published: November 2023

Purpose. To determine the specifics of the productivity formation in sugar sorghum cultivated on the low fertility soils under the influence of mineral fertilizer doses and sowing dates
Methods. Biological, statistical and mathematical methods were used in the study. Biological methods included field research. The obtained experimental data were processed statistically using descriptive statistics and variance analysis. The yield of biofuel and energy was determined by the calculation method.
Results. On the low fertility soils in the zone of unstable moisture in the western part of the Forest Steppe, the highest yield of bioethanol (1.75 t/ha), biogas (8.6 thousand m3/ha) and solid biofuel (18.5 t/ha) was obtained when sowing seeds of ‘Medovyi F1’ hybrid in the middle of May. The application of fertilizerscontributed to a significant increase in the yield of biofuel and energy. When applying fertilizers at a dose of N80P80K80, the yield of bioethanol per 1 ha increased by 0.5 and 0.6 t/ha, biogas by 2.7 and 3.1 thousand m3/ha, solid biofuel by 4.2 and 4.8 t /ha, and energy yield by 80 and 92 GJ/ha in variety ‘Sylosne 42’ and hybrid ‘Medovyi F1’, respectively. When applying a dose of N160P160K160, the yield of bioethanol increased by 0.3 t/ha, biogas by 2.1 thousand m3/ha, solid biofuel by 3.3 t/ha, and energy yield by 61 GJ/ha. Weather conditions (51.4%), varietal characteristics (17.5%) and fertilizer doses (12.3%) had the greatest influence on energy yield per unit area of sugar sorghum crops.
Conclusions. On low-fertile soils in the zone of unstable moisture, the highest yield of bioethanol (1.75 t/ha), biogas (8.6 thousand m3/ha) and solid biofuel (18.5 t/ha) was obtained by sowing seeds of the hybrid ‘Medovyi F1 in the middle of May. When applying fertilizers at a dose of N80P80K80, the yield of bioethanol increased by 0.5 and 0.6 t/ha, biogas by 2.7 and 3.1 thousand m3/ha, and solid biofuel by 4.2 and 4.8 t /ha in variety ‘Sylosne 42’ and hybrid ‘Medovyi F1’, respectively.

Authors: Nosov M. H. 
Published: November 2023

Purpose. Today, the search, research and implementation of new technologies for the production of solid fuel is important for the agro-industrial complex and renewable energy. Sorghum is considered as a strategic crop in the provision of feedstock for bioenergy and reclamation of degraded soils. The purpose of the study was to study and select the material for the creation of high-yielding hybrids of sugar and grain sorghum for the production of solid biofuel.
Materials and methods. The two-year results of the sorghum variety test at the Synelnykivska Experimental Station are highlighted. 68 samples were studied. They had a yield of green mass in the range of 23–79 t/ha.
Results. F1 hybrids (Nyzk.93s x Karlykove 45) formed the highest average yield of green mass — 65.2 t/ha; F1(Early776s x Karlykove 45) — 61.4 t/ha and F1(Dn71s x Karlykove 45) — 60.1 t/ha. The yield of hybrids Mammoth and F1(A158x Karlykove 45) was slightly lower, and amounted to 53.3 and 52.8 t/ha, respectively. F1 (Nyzkorosle 93s x Karlykove 45) stood out according to the average yield of dry matter of green mass — 17.6 t/ha; F1 (Dn17s x Karlykove 45) — 13.8 t/ha. According to the average indicators of the yield of solid fuel from 1 ha, the combinations F1 (Nyzk.93s x Karlykove 45) were the best — 12 t/ha; F1 (Dn17s x Karlykove 45) — 8.2 t/ha; F1 (Early 776s x Karlykov 45) — 7.9 t/ha. The best indicators in terms of energy output were the following combinations: F1(Low 93s x Karlykove 45) — 197.7 Gj/ha, F1(Dn71s x Karlykove 45) –135.5 Gj/ha, F1(Early 776s x Karlykove 45) — 129 Gj/ha.
Conclusions. High-yielding sorghum hybrids are the most economical and energetically expedient measures to provide feedstock for the bioenergy industry. A selected hybrid for the bioenergy application F1 (Nyzkorosle 93s x Karlykove 45) differs from the standard in terms of productivity and manufacturability. The value of the Karlykove 45 variety as a pollinator for the creation of hybrids for solid biofuel was also clarified. The agricultural sector of Ukraine has enough potential resources for biofuel production.

Authors: Blanco Rodríguez Guadalupe 
Published: November 2023

La tesis abordó el trabajo remunerado, doméstico y de cuidado que realizan las mujeres bolivianas y sus hijas en las quintas hortícolas de General Pueyrredon, poniendo en el centro del análisis a las personas y sus trayectorias. El foco estuvo en las experiencias de los trabajadores dentro de sus grupos domésticos y a las interacciones que establecen con la colectividad y los agentes estatales que circulan en el cordón frutihortícola, para observar las desigualdades y asimetrías que se constituyen entre ellos. La superposición de los espacios domésticos y de trabajo para el mercado que sucede en las quintas fue central para la tesis. En esa superposición, las actividades de la “vida pública” – trabajo remunerado- y de la “vida privada” –trabajo doméstico y de cuidado- se realizan en simultáneo y producen distintos efectos en sus trayectorias migratorias y laborales. En ese contexto, mostramos la división sexual del trabajo, los cambios que produjo en ella la mercantilización del trabajo de producción luego de la migración, mientras que analizamos como esa división sexual del trabajo, el estatus en lo familiar y la generación tienen efectos en el acceso a recursos y a las decisiones sobre el trabajo remunerado familiar. Por último, analizamos las formas en que los agentes estatales intervienen produciendo sentidos sobre el cuidado y la crianza en el marco de esa superposición de trabajos con jornadas extendidas y exigencias estacionales.

Introduction and Aim: “SARS-CoV-2” (Severe Acute Respiratory Syndrome Coronavirus -2), a member of the coronavirus family, is the culprit behind COVID-19 (coronavirus disease 2019). We intended to examine the risk factors for infection in patients presenting with corona virus in the emergency department and to report electrolyte disturbance, coagulopathy, procalcitonin, and mortality in COVID-19 patients. The aim was to examine how electrolytes, coagulation parameters, and procalcitonin are associated with mortality in patients with COVID-19.

Materials and Methods: Retrospective observational analysis, information on 106 individuals with SARS-CoV-2 infection was gathered, and survivors and non-survivors were further identified. Continuous parametric variables were statistically reported as Mean ±SD. Analysis was done on the relationship between biochemical markers and mortality.

Results: Substantially low Sodium (P = 0.09), Potassium (P = 0.01), and Chloride (P = 0.000) levels were identified in ‘severe COVID-19 patients’ with survivors than in non-survivors, although the p-value for chloride was significantly connected with non-survivors. No statistically significant data were reported for Prothrombin Time (PT). In patients in the survival group, there was an elevated International Normalized Ratio (INR) with a 0.05 p-value and a significant correlation (p = 0.04). With a p-value of 0.01 in both survivors and non-survivors, activated partial thromboplastin time (APTT) was marginally elevated dimer values were discovered to be noticeably higher in both survivors and non-survivors, and they were substantially connected with a p-value of 0.05. With a p-value of 0.01 the surviving group was shown to have higher procalcitonin levels.

Conclusion: This analysis demonstrates that the extremity of COVID-19 is linked to acid-base imbalance, coagulopathy, and death.

People of all ages are becoming more and more addicted to stimulant medicines and energy drinks for a variety of reasons, including work, sports, and leisure. There are several formulations with different flavors available on the market. Many of these items contain extremely high levels of caffeine as well as a wide range of stimulants that have an array of effects on various body areas. Caffeine use in such excess has been known to produce rhythm disturbances of the heart in healthy people, and when mixed with other stimulants, it can have a range of negative consequences on the way the body functions. Those who use it excessively daily, however, are unaware of the potentially fatal risks linked to these items. We describe a case of a 27-year-young man who presented with new-onset supraventricular tachycardia due to excessive consumption of energy pills that contained high amounts of caffeine. This individual had no significant past medical history and was not a smoker or a regular alcohol drinker.

Published: November 2023

Introduction: Evidence suggests that patients with diabetes who developed the COVID-19 infection are known to have glycaemic instability, impaired immunity and associated comorbidities such as heart diseases and obesity leading to increased risk of mortality. Hence the current study was planned to assess the factors affecting mortality in diabetic COVID-19 patients admitted in tertiary care hospitals in South India.

Methods: This was a retrospective study involving diabetic COVID-19 patients hospitalized in South India, data was collected from hospital records using pre-tested semi-structured validated questionnaire from January 2021 to February 2022.

Results: Out of 397 study patients, 66% (263) them were males. Mean age of the patients was 61± 11.6, male 60.6±11.8, and female was 61.5±11.3. Most common presenting symptoms were fever 62% (235), cough 47% (172), breathlessness 42% (149), followed by weakness 29% (114). 46% (184) patients had uncontrolled diabetes. Co-morbidity like hypertension etc., were seen in 63% (250) of the patients. Saturation below 93% was seen in 20% (75) patients. 26% (69) were on ventilators, 48(42%) were admitted in intensive care unit. Laboratory profile showed high C-reactive protein in (86%) 264, elevated D-dimer in 86% (240), low lymphocyte in 46% (182), elevated ferritin in 63% (177), high neutrophil in 30% (118) and low Hb in 24% (85). Radiological finding shows interstitial opacity in 58 % (148) and CT-ground glass opacity in 21% (86). Complications like acute kidney injury were seen in 29% (115) and acute respiratory distress in 10% (39). The case fatality rate was 14% (56). Elevated neutrophil, elevated aspartate aminotransferase, low oxygen saturation was found to be significantly associated with mortality in COVID-19 diabetic patients.

Conclusion: In diabetic COVID 19 patients elevated aspartate alanine transaminase, neutrocytosis and oxygen saturation below 93% are independent risk factors for mortality.

Authors: Ghaffar Husain Alyaa , Abdullah Laftaah Alrubaii Bahaa 
Published: November 2023

Introduction and Aim: Pseudomonas aeruginosa virulence factors genes are a growing concern as they are involved not only in its pathogenicity, but also cause bacterial resistance to multiple classes of antibiotics. Laboratory identification of clinical isolates carrying the virulence genes would be critical in limiting the bacteria's spread and reducing its pathogenicity. The purpose of this study was to investigate a simple and inexpensive real-time PCR test to find the level of expression of Pseudomonas aeruginosa virulence genes before and after treatment with specific concentration of Lactobacillus acidophilus cell-free supernatants (CFSs).

Materials and Methods: Between December 2021 and June 2022, 350 clinical samples collected from Baghdad hospitals, Iraq, were tested for the presence of P. aeruginosa. The P. aeruginosa isolated were tested for their antimicrobial susceptibility using the Kirby-Bauer disk diffusion method. P. aeruginosa virulence genes were detected by using the reverse transcription-PCR method. The expression levels of these genes before and after treatment with Lactobacillus acidophilus cell-free supernatants were measured by real-time PCR.

Results: Out of 350 samples tested, 60 isolates were positive for the presence of P. aeruginosa. Antibiotic susceptibility tests revealed a high level of antibiotic resistance, while genetic techniques identified the presence of several virulence genes that exhibited variable expression under the influence of Lactobacillus acidophilus supernatants.

Conclusion: The study findings showed that L. acidophilus supernatants had an effect on reducing the expression of certain virulence genes of P. aeruginosa, implying that L. acidophilus could be used as an option in treating P. aeruginosa infection.

Published: November 2023

Introduction and Aim: Although the pathophysiological processes underlying the association between congestive heart failure (CHF) and osteoporosis (OP) are unknown, there is evidence that several changes observed in CHF may play a role in bone loss. The objective of the study is to examine the impact of soluble TNF-alpha receptor 1 (sR1-TNF-alpha) and soluble TNF-alpha receptor 2 (sR2-TNF-alpha) on the risk of fractures in patients with OP associated with CHF and type 2 diabetes mellitus (T2DM).

Methods: This study included 178 women aged 50–65 years, divided into four groups. Group 1 consisted of 48 women diagnosed with HF and T2DM. Group 2 included 93 patients with OP and HF. Group 3 consisted of 37 women with OP, HF, and T2DM.

Results: The levels of sR1-TNF-alpha and sR2-TNF-alpha in patient groups 1 through 3 were significantly higher than in the control group (p<0.01). Furthermore, it was demonstrated that patients in group 3 had much greater levels of both receptors than those in groups 1 and 2.

Conclusion: High levels of sR1-TNF-alpha and sR2-TNF-alpha in postmenopausal women with CHF are associated with an increased risk of a poor outcome during OP.
