Published: October 2022

Introduction: Carbon monoxide (CO) poisoning is one of the most common forms of intoxication around the world. One of the complications associated with CO exposure is direct toxicity to the skeletal muscles. Though compartment syndrome induced by CO intoxication is rare, it is a well-known complication. In this study, we present a case of CO poisoning in a patient who developed compartment syndrome in his forearm. Case report: A 22-year-old man was found unconscious in a motel where a briquette had burned. He was later diagnosed with rhabdomyolysis associated with CO poison- ing. After he regained consciousness, he experienced difficulty in moving his left arm, with sensory impairment in the same arm. He was diagnosed with compartment syndrome, and an emergency fasciotomy was performed. One month later, electromyography was performed which revealed left median, ulnar, radial and musculocutaneous nerve palsy. Discussion: Compartment syndrome induced by CO intoxication is rare but is a well-known complication. Compartment syndrome is a limb-threatening and life- threatening condition. If untreated, the pressure in the muscle may rise, which can lead to tissue necrosis. Generally, nerve paralysis does not occur in CO poisoning. In our case, it occurred as median, ulnar, radial and musculocutaneous nerve palsy. Conclusion: Side effects of CO poisoning can be extant, especially for those who are unconscious since they cannot express pain, numbness, and motor weakness. It is important to not overlook compartment syndrome, to double-check whether there is swelling, change in skin color, or skin firmness in extremities, and to observe the patient closely.

Emphysematous cystitis is an uncommon acute infection of the underlying bladder musculature and mucosa, caused by gas-producing organisms. Here we describe an 87-year-old woman with diabetes mellitus and emphysematous cystitis who was successfully treated with hyperbaric oxygen (HBO2) therapy. Her predisposition of diabetes and infection with gas-producing bacteria was considered to precede the development of emphysematous cystitis. Computed tomography revealed gas accumulation in the bladder wall and lumen. Antibiotics and HBO2therapy were administered. HBO2 therapy may be beneficial due to the improvement in oxygenation of the tissues affected by the disease. HBO2 is a useful adjunct therapy for the management of severe emphysematous cystitis.

In any kind of diving there is a risk of accidents, as the move from the topside environment to underwater can affect a diver’s physiological and psychological condition. It is important to investigate dive accidents to clarify the causative factors and determine preventive measures. In this study, autopsy files of fatal dive accident cases were reviewed to evaluate demographic data, type of diving, purpose of dive, seasonal distribution, autopsy findings, and causes of death. We reviewed 56 fatal dive accident files from autopsy units in cities where dive activities are concentrated and from the archive of the Turkish Underwater Federation. Four cases were excluded from the study since we were unable to obtain autopsy reports. Of 52 cases there were 20 scuba divers, two surfacesupplied divers and 30 breath-hold divers. The majority of cases involved males (94%). The average age of 50 cases was 38.6; age estimation for two cases could not be determined due to advanced putrefaction. Of these fatal dive accidents 75% took place over a period of six months between May and October. Drowning was recorded as the primary cause of death in these cases. X-ray imaging was used in four (8%) cases. A special autopsy technique was used for nine (17%) cases, to detect possible pulmonary barotrauma and arterial gas embolism. The forensic specialist who is planning to conduct the autopsy for a dive fatality should have knowledge and experience about dive physics and physiology as well as physiopathology of dysbaric injuries.

Introduction: Hyperbaric oxygen (HBO2) therapy is emerging internationally as the primary treatment modality for inflammatory pathways related to neurological disorders. Currently, literature concerning its effectiveness in autistic children is limited. Using neurocognitive tests and clinical-diagnostic evaluations, this study evaluates the clinical, cognitive and behavioral effects of HBO2 on children diagnosed with autism. Methods: An experimental HBO2 group (EXP: F = 1; M = 7; mean age: 7 ± 2.33; years) and a control non-HBO2 group of autistic children (CTRL: F = 2; M= 5; mean age: 6.6 ± 2.7 years) correctly completed the Aberrant Behavior Checklist-Community (ABC) before HBO2 (T0), after 40 sessions of HBO2 (T1), and one month after the end of treatments (T2). Additionally, the experimental HBO2 group was evaluated with the Childhood Autism Rating Scale at T0 and T2. Results: Total ABC score was lower at T2 (mean ± SD: 50.38 ± 18.55; p < 0.001) compared to scores obtained at T0 (mean ± SD: 57.5 ± 19.01). Similarly, in the control group the total ABC score differed statistically (p < 0.05) between T0 (103.6 ± 20.38) and (T2: 59 ± 25.25). Conclusions: Despite the improvements reported in both groups, our results do not support the utility of HBO2 in children diagnosed with autism.

Objective: Analyze the influence of the hyperbaric environment on skeletal muscle mitochondrial bioenergetic end-points of rats submitted to muscle contusion. Methods: Twelve female Wistar rats were randomly assigned to three groups. All rats were submitted to muscle contusion in the right gastrocnemius through a standard protocol. The control group (C) remained under normo- baric conditions without any treatment. The hyperbaric air (HB) and the hyperbaric oxygen (HBO2) groups had four sessions of HBO2 therapy 60 minutes, six, 12, 24 and 48 hours after the injury at 253.25 kPa (2.5 atmospheres absolute/ATA) with air or 100% oxygen, respectively. The animals were sacrificed 48 hours after muscle injury, and both muscles (injured and non-injured) were analyzed. Muscle mitochondrial bioenergetics and mitochondrial permeability transition pore (MPTP) susceptibility were evaluated. Results: Significant differences were found in all parameters between the injured and the non-injured gastrocnemius in the C group. In the HB group, significantly better results concerning bioenergetics-related end points with complex I and II substrates where found in the right gastrocnemius, whereas in the HBO2 group the time to Vmax (time that elapsed until the faster swelling kinetics starts) was significantly higher and the swelling amplitude was significantly smaller than in other groups, which suggest a lower susceptibility to MPTP opening. Conclusion: The present data suggest that hyperbaric exposure, particularly with oxygen, positively modulates the efficiency of skeletal muscle mitochondria after muscle contusion.

We previously published our method of performing continuous bladder irrigation (CBI) in a monoplace hyperbaric chamber [1]. This method entailed the use of an IV pump to infuse saline into the monoplace chamber. The specter of causing iatrogenic rupture of the bladder was raised following such a case, reported herein, of a woman with hemorrhagic radiation cystitis leading to cystectomy. Due to the danger of bladder rupture while providing CBI with a pump, we retract our previously reported method and encourage the use of either a gravity-fed system or delay in hyperbaric oxygen therapy treatment until CBI is no longer necessary.

The Eurasian Tunnel is a 5.64-km crossroad tunnel that connects Europe and Asia. Located under the seabed for the first time, 3.34 km of the tunnel that crosses the Bosphorus was built by advanced tunneling techniques. An exclusively designed tunnel boring machine (TBM), which has an operating pressure of 11 bars and a diameter of 13.7 meters was used for boring the seabed tunnel. The deepest point was 106 meters below sea level. One bounce diving period and seven saturation diving periods were needed for the repair and maintenance of the TBM during the project. Total time spent under pressure was 5,763 hours. A saturation decompression chamber for four divers was used for the saturation interventions, and divers breathed trimix at storage and excursion depths. The longest saturation run was the second, with storage at 10 bars and excursions to 10.4 bars. Twenty-three professional divers who were all experienced in compressed-air work were assigned to work on the project. Four dive physicians provided medical support, which included screening of divers before and during the hyperbaric interventions as well as on-site supervision. There were no diving-related accidents. A minor hand trauma, an external otitis and occasional insomnia were non-diving-related health issues that occurred during saturation and bounce diving. To our knowledge, the Eurasian Tunnel was the first project to perform TBM repair operations at such depths under the seabed and the first saturation diving in Turkey. In this report, we aimed to share our experiences of hyperbaric medical consulting in support of this type of tunneling project.
Updates in diving medicine: evidence published in 2017-2018
Authors:   Duke Center for Hyperbaric Medicine and Environmental Physiology, Duke University Medical Center, Durham, NC, U.S, Keuski Brian M.
Published: October 2022

This report summarizes some of the most relevant studies during the 2017-2018 academic year of scientific literature for diving medicine. The article selection is the result of a PubMed search for “diving,” as well as a manual review of the journals Undersea and Hyperbaric Medicine and Diving and Hyperbaric Medicine. Four articles were published reporting on new advances in decompression modeling. New consensus guidelines in the prehospital treatment of decompression sickness were published as well as a retrospective review of the efficacy of the U.S. Navy Treatment Tables. Several articles were published this year researching cardiovascular health and fitness to dive. A novel approach by one occupational medicine clinic for referral for hypertension may allow for early intervention of the “silent killer.” Application of the Framingham risk score to commercial divers does not result in an excessive number of disqualifications. The controversy over screening and subsequent repair of a patent foramen ovale in divers was heavily researched this past year. Several groups reported their experience with closure and associated risks. Subjects diving with pre-existing conditions were surveyed and found to be fairly common, with seemingly little ill effect (albeit with a potential survivor bias). Recommendations for diving while using antidepressants were reported. Several articles were published utilizing point of care ultrasound in the diagnosis of immersion pulmonary edema (IPE). One case of a using sildenafil as a preventative medication in a triathlete with an extensive history of IPE may prove promising for further research. Finally, an extensive review article pertaining to hypercapnia in diving was published as well as the use of pulse oximetry as an early warning system to prevent hypoxia in rebreather divers.

Published: October 2022

A concorrência do mercado de trabalho aliado à disputa para melhores vagas faz com que os trabalhadores da saúde dediquem tempo em excesso ao seu emprego. Além disso, a sobrecarga de estresse físico aliada a grande carga horária, estresse psicológico e óbitos de pacientes, podem gerar insatisfação no ambiente de trabalho. Com isso, sintomas depressivos, esgotamento profissional, falta de prazer no ambiente de convivência e estresse emocional podem ocasionar o desenvolvimento da Síndrome de Burnout. A pesquisa é relevante visto que buscou analisar os fatores de risco para o desenvolvimento da Síndrome de Burnout em profissionais da área de saúde. A metodologia iniciou com a abordagem de profissionais de saúde na residência médica com uma amostra de 24 indivíduos. A coleta de dados consistiu na aplicação de questionários digital online que incluiu: socioeconômico, WHOQOL (World Health Organizativo Quality of Live Bref) e MBI (Maslach Burnout Inventory). Os resultados se deram através do cruzamento dos dados que demonstraram que 81,81% declararam que trabalhar em conjunto com pessoas exige um grande esforço algumas vezes na semana e 54,55% relataram se sentirem emocionalmente exaustos com o trabalho com carga horária semanal acima de 50 horas. A rotina de trabalho dos médicos residentes demonstrou uma carga horária exaustiva associada à demanda psicológica alta devido à pressão pessoal e de chefia. Dentre os participantes, o esgotamento profissional e despersonalização estavam presentes em mais da metade que apresentaram essas características durante algumas vezes por semana. Logo, foram encontrados fatores de risco prévios para o desenvolvimento de Síndrome de Burnout.

Authors: Sorano Enrico , Giovando Guido , Rizzi Alessandro , Sardi Alberto
Published: October 2022

The increase in claims for compensation by patients to public healthcare companies highlights the key role of the provision for risks and charges. The resources set aside in the provision for risks determine the ability to cover losses or debts of determined nature, of certain or probable existence, of which, however, either the amount or the date of occurrence is undetermined. The research aims to identify the evolutionary trend of the provision of risk in national public healthcare companies. Moreover, it forecasts the future trend of provision for risks divided per the protection of civil liability towards third parties model. The research adopts a quantitative methodology to facilitate replicability and to investigate the trend of the provision for risks of a national public healthcare context, i.e., Italian public healthcare context. The research data set includes accounting information collected by websites of healthcare facilities in order to comprehend the evolutionary trend of the provision for risks. The results of the research describe a stable trend in the resources set aside in the provision for risks, a continuous decrease in the use of the provision for risks with a consequent increase in the fund itself, and a discontinuous trend in the percentage ratio between the annual provisions for the risk and the fund itself.

Purpose: To explore the screening value of the adenoidectomy /
nasopharyngeal (A/N) ratio from nasopharyngeal lateral radiography in
children with obstructive sleep apnoea hypopnea syndrome (OSAHS).
Methods: Children who had visited the respiratory department due to
snoring and/or mouth breathing’ were enrolled. Nasopharyngeal lateral
radiography and polysomnography (PSG) were performed. PSG monitoring is
the gold standard for OSAHS. The differences in PSG monitoring results
among different A/N groups were compared, and the correlation between
the A/N ratio and PSG monitoring results was analysed. The receiver
operating characteristic curve (ROC) was plotted to evaluate the
screening value of OSAHS in children with the A/N ratio from
nasopharyngeal lateral radiography to determine the diagnostic critical
point. Results: A total of 425 children were enrolled. A total of 183
patients (43.1%) were diagnosed with OSAHS, including 113 cases
(26.6%) of mild OSAHS and 70 cases (16.5%) of moderate to severe
OSAHS. A total of 52 patients (12.2%) had an A/N ratio ≤ 0.60, 77
patients (18.1%) had an A/N ratio from 0.61~0.70, 142
patients (33.4%) had an A/N ratio from 0.71~0.80, and
154 patients (36.2%) had an A/N ratio ≥0.80 The patients with
moderate-severe OSAHS had a higher A/N ratio than those with mild OSAHS
and non-OSAHS. The OAHI, ODI, and the diagnostic rate of OSAHS were
higher and the LSaO 2 was lower in the A/N≥0.80 group than in the other
three groups. Spearman’s rank correlation showed that the A/N ratio was
correlated with OAHI, ODI, and LSaO 2 (r=0.275, 0.227, -0.225,
respectively). The area under the ROC curve for the diagnosis of OSAHS
by the A/N ratio was 0.659, the critical value was 0.825, and the
sensitivity and specificity were 45.1% and 80.9%, respectively. An A/N
ratio ≥0.825 was identified as the main influencing factor of OSAHS by
logistic multivariable regression analysis. Conclusion: There is a
correlation between the degree of adenoid hypertrophy and OSAHS, and an
A/N ratio ≥0.825 has good suggestive value for the diagnosis of OSAHS
but is not a substitute for PSG.
Effect of Hyperthermic Intraperitoneal Chemotherapy (HIPEC) on survival and recurrence rates in advanced gastric cancer: A systematic review and meta-analysis.
Authors: Patel Maitreyi , Arora Amandeep , Mukherjee Dipankar , Mukherjee Samrat
Published: October 2022

Background and methods: Around 5-20% of patients who undergo surgery
for advanced gastric cancer have peritoneal carcinomatosis. Peritoneal
recurrence rate is 10-54%, which is associated with poor prognosis. The
role of hyperthermic intraperitoneal chemotherapy (HIPEC) in advanced
gastric cancer is not clearly defined. We conducted a meta-analysis, in
accordance with the PRISMA guidelines, of the clinical trials and
high-quality non-randomized studies evaluating the role of HIPEC in AGC
over the last 10 years. Clinical data including overall survival,
recurrence-free survival, overall recurrence rate, peritoneal recurrence
rate, and complications analyzed using RevMan5.4. Results: Six
randomized controlled trials and 10 nonrandomized studies, comprising a
total of 1700 patients were included. HIPEC was associated with
significantly improved OS at 3 (OR 1.89, 95% CI 1.17-3.05) and 5 years
(OR 1.87, 95% CI 1.29-2.71). HIPEC was associated with reduced overall
recurrence (OR 0.49, 95% CI 0.31-0.80) and peritoneal recurrence (OR
0.22, 95% 0.11-0.47). HIPEC was not associated with increased
complications. The occurrence of postoperative renal dysfunction was
significantly higher in the HIPEC group (OR 3.94, 95% CI 1.85-8.38).
Conclusion: HIPEC may improve survival rates and reduce recurrence rates
in patients with AGC, without any significant increase in complications
with a favorable impact on survival.

Hyperaccumulator plants are able to tolerate extremely high concentrations of metals/metalloids in the soil in which they grow and to accumulate high concentrations in their shoots. To date, a total of 31 hyperaccumulator plant species have been identified in the Balkans, the centre of diversity and speciation in the European flora which is particularly rich in ultramafic areas. A further 8 species have yet to be confirmed through additional studies. Most of the 31 hyperaccumulator taxa (13 taxa or 41.9%) are species of the genus Odontarrhena, all hyperaccumulating Ni, but concentrations of this element above the hyperaccumulation threshold were also found in the genera Bornmuellera and Noccaea (all Brassicaceae), Orobanche (Orobanchaceae), Centaurea (Asteraceae) and Viola (Violaceae). The existence of hyperaccumulators of Tl and Zn is of particular interest because very few species worldwide hyperaccumulate these elements. Multiple metal hyperaccumulation was found in Noccaea kovatsii, as the hyperaccumulation of Zn was found in this species in addition to Ni, the primary accumulated element. Metal hyperaccumulation is discussed in terms of phylogenetic relationships and species distributions, with special attention to their systematics, the detection and recognition of new hyperaccumulating species and the possibilities for their future practical applications in phytotechnologies.

Published: October 2022

This research project aimed to analyse the biological potential of aqueous,
ethanolic, methanolic, and ethyl acetate extracts of red grape stalks, as
well as lyophilised red grape stalks from Krnjevo (Serbia). The
concentration of the total phenols and flavonoids, as well as the
antioxidant activity of the stalk extracts were measured by means of the
spectrophotometric method. In vitro antimicrobial activity of 23 selected
species of microorganisms (13 species of bacteria and 10 species of fungi)
was evaluated by determining the minimum inhibitory concentration (MIC) and
the minimum microbicidal concentration (MMC). The results indicated that the
highest concentration of total phenols was measured in the ethyl acetate
extract (60.08 mg GAE/g of extract), while the highest total flavonoid
concentration was observed in the acetone extract (34.24 mg RUE/g of
extract). The tested extracts showed poor antioxidant activity compared to
chlorogenic acid. The acetone extract probably showed the strongest
antimicrobial activity due to the high concentrations of phenols and
flavonoids. The tested extracts showed a better effect on Gram-positive
bacteria than on Gram-negative bacteria. Although grape stalks are a
by-product in the wine industry, they are a potential source of natural
compounds which can be used for a variety of purposes in many fields ranging
from the food industry to medicine.

Monitoring the presence of invasive species in natural wetlands is crucial for numerous reasons, including their negative impact on biodiversity, conservation and the ecosystem services provided by these important fragile areas. The aim of this paper was to investigate the presence and distribution of the highly invasive liana Echinocystis lobata (wild cucumber), and to determine its coenological relations with the native plant species in the Ramsar sites of the southern part of the Pannonian Plain (the southeastern part of Central Europe, northern Serbia). We conducted the phytocenological research of the selected protected riparian areas in detail over a six-year period (2011-2015 and 2020). This study revealed the significant presence of the highly invasive species E. lobata in the studied sites. Wild cucumbers were found in 146 plots in four out of the seven investigated areas. Cluster analyses distinguished four groups of relev?s dominated by E. lobata, which were described, and their dominant and constant species were identified. Habitat type identification was done, and the habitat preferences of E. lobata were determined. The spatial distribution of the four groups is such that they occur in a number of different habitat types or local communities. The species pool which makes up each of these four groups is thus geographically larger than the local community under study, so we can treat them as independently established and well-defined new community assemblages. Plant communities dominated by the invasive species E. lobata have not been described previously. Therefore, this work provides new data, and contributes to the further research and comparative analyses needed to describe invasive plant communities dominated by wild cucumber. In addition, the identification of habitat types which are most occupied by E. lobata is very important for managers of protected areas, as it allows them to better control and remove this highly invasive species, but also to prevent its further spread.

this research was to provide more detailed palynomorphological data on
selected taxa whose pollen grains are characterised by tricolpate apertures
(Pterocephalus plumosus, Succisa pratensis and Succisella inflexa). The
pollen morphology of P. plumosus was studied using both light microscopy and
scanning electron microscopy. The pollen grains are tricolpate, suboblate to
prolate; large in size. Their outline in polar view (amb) is subcircular,
rarely trilobate. The brevicolpi have a distinct margo and acute ends. The
exine sculpture is echinate-microechinate-nanoechinate. The exine structure
(columellae) of the pollen grains of P. plumosus, S. pratensis and S.
inflexa was analysed for the first time in the current study. Pollen grains
in P. plumosus are distinguished by long and dense columellae in the
mesocolpia, and longer in the apocolpia. Our new ?alynomorphological data
support a close relationship between S. pratensis and S. inflexa by the
presence of shorter sparse columellae throughout the pollen exine. The UPGMA
dendrogram shows the distinctive morphometric characters of P. plumosus
pollen grains, which is thus included as a separate branch.
Resorption of N, P and K from the floating and submerged leaves of the aquatic fern Salvinia natans
Authors: Adamec Lubomír
Published: October 2022

Nutrient resorption from senescing leaves and shoots decreases the nutrient
losses associated with biomass turnover and represents a significant
component of mineral nutrient economy. In submerged aquatic plants, N and P
resorption efficiencies (REN, REP) from senescing leaves or shoots are high
(usually >40% in dry weight, DW), but K resorption efficiency (REK) is
usually very low or zero. The free-floating aquatic fern Salvinia natans has
a linear, modular shoot structure exhibiting steep growth and a
physiological polarity, and consists of oval, floating, natant leaves with
photosynthetic functions and thread-like submerged leaves which absorb
nutrients. To obtain the basic mineral nutrient characteristics, REN, REP
and REK were estimated in the senescent floating and submerged leaves of
this species grown in an outdoor culture. The N content in all the leaves
was in the range between 1.10-1.42% DW, P 0.33-0.57% DW and K between
4.03-6.20% DW, indicating a partial N growth limitation but a liberal P
uptake. Contrary to expectations, the REN values in both types of leaves
were relatively low (7-31%), those of REP even negative (-7 to -12%), while
the REK values were relatively high (31-44%). These results are in contrast
to much higher N and P resorption efficiencies reported in both submerged
plants and the similar tropical species S. molesta. The REK values found in
S. natans are in accordance with those reported in S. molesta, but are much
higher than those in submerged plants. Thus, the submerged leaves
(rhizophylls) of the Salvinia species do not behave in the same way as the
leaves of higher submerged plants in terms of the K economy.

Published: October 2022

Headspace sampling is a fast, simple and economical way to prepare plant
samples for analysis by gas chromatography. For the first time, the
composition of the head space volatiles (HSV) of six Salvia species (S.
verticillata, S. glutinosa, S. nemorosa, S. aethiopis, S. amplexicaulis and
S. officinalis) in the flowering stage and two (S. glutinosa and S. sclarea)
in the fruiting stage from Southeastern Serbia was analysed using the
GC-FID-MS technique after headspace sampling. The chemical composition of
the highly volatile compounds of the analysed species varies considerably.
Monoterpene hydrocarbons represented the dominant class of volatile
compounds in all the Salvia species, except for S. sclarea and S. aethiopis.
The content of sesquiterpenes was the highest in S. aethiopis (96.9%) and S.
glutinosa in the flowering phase (29.5%), while in all the other samples
that percentage was below 10%. Oxygenated monoterpenes were the most
abundant in S. sclarea, where the main component was oxygenated monoterpene
linalyl acetate (97.7%). The main component of S. verticillata was
?-phellandrene, and its content varied depending on the plant location and
sampling time. The main component of S. glutinosa in the flowering phase was
limonene (16.6%), and in the fruiting phase sabinene (87.1%). Headspace
analysis of the volatile components of S. aethiopis was carried out for the
first time and the most abundant detected components were sesquiterpenes:
(E)- caryophyllene (36.8%), ?-copaene (33.4%) and ?-elemene (7.3%). The
analysis of the principal components was performed to interpret the grouping
patterns, as well as to analyse the similarities and differences between the
samples in terms of the composition of the volatile components. The samples
were grouped into three clusters. The first cluster consisted of samples of
S. verticillata (S1, S4 and S5) from different locations, the second
comprised samples of S. glutinosa (S3), S. aethiopis (S8), S. amplexicaulis
(S9) and S. officinalis (S10), while samples of S. nemorosa (S7) made up the
third cluster. The HS-GC-FID-MS technique can be successfully used for the
qualitative and quantitative analysis of volatile compounds of different
Salvia species. The obtained results are important for evaluating the
possibility of using different types of sage.

Published: October 2022

Seasonal variations in the environment (e.g. of temperature and light intensity) can lead to the excess production of reactive oxygen species and oxidative stress, inducing changes in the permeability of the plant cell membrane and the structure and function of cellular molecules. To address these deleterious effects, plants activate various non-enzymatic and enzymatic antioxidants. This study seeks to detect the influence of seasonal variation in Hedera helix (ivy) leaves, collected in Banj brdo (Banja Luka, Republika Srpska, Bosnia and Herzegovina) between December 2017 and November 2018, on oxidative (hydrogen peroxide and malondialdehyde) and antioxidant (superoxide dismutase, catalase, Class III peroxidases, and phenolic compounds) parameters. During the winter-early spring months (a temperature range of 0.7 to 5.4?C), we detected an increase in the values of all the oxidative and antioxidant parameters, whereas during the spring, summer, and autumn months (a temperature range of 15 to 25?C), the values of most of these parameters fell. However, a peak in the parameter values was detected during June and July 2018, which might be attributable to the influence of the changes in both light intensity and temperature and to the effects of intensive shoot growth. Our results highlight the importance of the antioxidant protection system of H. helix for its acclimation to seasonal variations in the environment, especially temperature.

The influence of siam weed compost and inorganic fertiliser applications on tomato performance
Authors: Akinrinola Tajudeen , Tijani-Eniola Hassan
Published: October 2022

Tomato is an important vegetable crop with high soil nutrient requirements.
Hence, improvement in soil fertility status must be met through the use of
readily available nutrient sources. Chromolaena odorata is widely spread in
the country, and its compost has the potential of improving tomato yield.
However, there is a dearth of information on the response of tomatoes to
Chromolaena Compost (CC) and NPK fertiliser interactions. In the 4 x 3
factorial arrangement, CC at 0, 6, 8 and 10 t/ha and NPK 15-15-15 at 0, 15
and 30 kg N/ha were evaluated in a completely randomised design and a
randomised complete block design for pot and field studies, using 10 kg/pot
soil and 33333 plants/ha, respectively, with 3 replicates. Data on growth
and yield parameters were subjected to analysis of variances by using SAS
version 9.0. In the pot, the interaction of 8 t/ha of CC and 30 kg N/ha of
NPK 15-15-15 fertiliser gave a significantly higher number of leaves, number
of branches, leaf area and the highest fruit set at 49 days after
transplanting compared to other treatments. In the field, the number of
fruits/plant (20.89) was significantly higher with the interaction of 10
t/ha of CC and 30 kg N/ha of NPK 15-15-15 fertiliser, while 8 t/ha of CC and
30 kg N/ha of NPK 15-15-15 fertiliser treatment gave the significantly
higher fruit size (64.61 g) and yield (31.73 t/ha) compared to the control
(11.33, 32.09 g and 9.66 t/ha, respectively). The application of 8 t/ha of
CC with 30 kg N/ha of NPK 15-15-15 fertiliser was therefore recommended.

Published: October 2022

The low seed yield of kenaf in different agro-ecologies in southwestern
Nigeria has been partly attributed to the effect of climate change. An
experiment was, therefore, conducted to determine the response of kenaf to
prevailing weather conditions and the most appropriate planting time to
produce optimum seed yield of acceptable quality that will be profitable in
humid agro-ecologies of Nigeria. The study was conducted at five research
stations (Ibadan, Ilora, Ikenne, Orin Ekiti and Kishi) of the Institute of
Agricultural Research and Training (I.A.R.&T) in Ibadan, Nigeria, in the
2018 and 2019 planting seasons (June to August). Seeds of five varieties of
kenaf (Cuba108, Ifeken DI 400, Ifeken100, Ifeken 400 and Tianung-2) were
planted at monthly interval between June and August of each year in a
randomised complete block design (RCBD) with three replicates. Harvesting,
threshing and cleaning were manually done, and samples of clean seeds were
analysed for seed quality. Data were obtained on plant height at harvest,
seed yield-related traits and seed quality parameters. Profitability
analysis was also conducted to estimate the cost and returns to production
in the different locations. Kenaf seed yield and quality were highly
influenced by the production environment. It is concluded that planting of
kenaf in mid-June in southwestern Nigeria will give optimum seed yield of
high quality with profitable gross return on investment.
Structural and luminescence properties of SrGd2O4 nanocrystalline phosphor doped with Dy3+ and Sm3+

Published: October 2022

In this manuscript, down-conversion nanopowders of SrGd2O4 doped with
different concentrations of either Dy3+ or Sm3+ ions were examined in
detail. All samples were prepared via glycine-assisted combustion method,
primarily burned at 500?C for 1.5 h and additionally calcined at 1000?C for
2 h, at ambient room temperature. The XRD analysis showed that all samples
crystallize as single phase and the orthorhombic lattice SrGd2O4. TEM
analysis determined high degree of crystallinity of samples with grain size
of approximately 200 nm for Dy3+ doped and 150 nm for Sm3+ doped SrGd2O4.
For both samples SAED confirmed that diffraction rings correspond to the hkl
plane indices of SrGd2O4, while EDS confirmed presence of Dy in crystal
structure. Results of luminescent characterization demonstrated all
appropriate emission peaks related to either Dy3+ or Sm3+ dopant ions.
Investigation of dopant concentration revealed that the lowest values of
both dopants have the most prominent emission peaks, while coordinates
obtained from the CIE diagram showed emission shifting with the change of
concentration.
