Phosphorus (P) is an essential nutrient for wheat production and about half of total P fertilizers are consumed by only wheat in Pakistan. Hence, keeping in mind the ever-increasing input cost of P fertilizers, it becomes highly imperative to identify modern wheat genotypes for their P-use-efficiency.  The experiment was consisted two factor completely randomized design  (CRD) with three replications. Factor A comprised of two levels of soil applied P i.e.0 Kg ha-1 (Control) and 90 Kg ha-1, while factor B involved six wheat genotypes (Benazir, Imdad -2005, TD-I, Kiran-95, Tj-83, Sindhu). Results showed that as against its deficient condition, adequate P nutrition (90 kg P ha-1) enhanced shoot length (28%), root length (8.9%), fresh shoot weight (97%), fresh root weight (20%), no of leaves per plant (9.3%), leaf area index (130%), dry weight of shoot (83%), dry weight of root (16.5%) of wheat genotypes. Wheat genotype exhibited wide genotypic variation for their P biomass efficiency. Most interestingly, the Phosphorus efficiency ratio (PER) of the wheat genotypes was greater for TJ-83 and Sindhu. The genotype TJ-83 and Sindhu were the most biomass productive genotypes followed by Benazir and Kiran-95 in the uthal region of the Baluchistan. The study concluded that under P deficiency stress, enhanced efficient wheat genotypes determines their growth and biomass production. The genotype Sindhu was categorized as ‘efficient-responsive’ wheat genotype in terms of biomass production, most desirable both for low and high input sustainable agriculture system, Further validation of these results is required under field conditions at Uthal region Balochistan.

Salinity is a brutal threat to sustainability of crop production and exhibits injurious effect on major plant processes including protein synthesis, cell division and photosynthetic activity. Germination and early growth of plants are most susceptible to salinity effect in comparison to other growth stages. In this context, the seed emergence and early vegetative growth of flowers needs to be tested properly. The pot based study was conducted in Completely Randomized Design (CRD) with three replicates at Sindh Agriculture University Tandojam. The goal of this investigation was to explore the performance of petunia plants to salt stress environment at early growth stage.  Two petunia varieties (V1= Prism blue, V2= Hala lop petunia rose) were evaluated against six levels of salt stress (T1 = Canal irrigation water [Control], T2 = 3 dS m-1, T3 = 5 dS m-1, T4 = 7 dS m-1, T5 = 9 dS m-1, T6 = 11 dS m-1).The results showed that there was an inverse effect of salt stress on all the traits examined and with each increased level of salinity in irrigation water; the values of petunia plant traits were significantly decreased. The petunia grown in pots given only canal water (control) revealed better performance for germination and growth attributes. It was further noted that that salt stress up to 3 dS m-1 level was generally tolerated by petunia. Among petunia varieties, Hala lop petunia rose performance was better and showed relative tolerance to salt stress over Prism blue, but in most cases the differences were insignificant (P>0.05).

Citrus (Citrus sinensis L.) is one of the world's most significant fruit crops, 3rd among subtropical fruits. Kinnow is considered as the trademark of Pakistan’s citriculture industry, dominates the major citrus growing areas of the country. Macro and micronutrients have the capacity to regulate and manipulate the growth and fruit quality of Kinnow mandarin. The present study was initiated to evaluate the influence of foliar sprays of nutrients on yield and fruit quality of Kinnow mandarin. For this purpose, foliar sprays of nitrogen (1 and 1.5 %), iron (0.25 and 0.5 %) and zinc (0.25 and 0.5 %) were applied at pre flowering stage. The trial was carried out using a randomized complete block design (RCBD). The parameters such as reducing sugars (%), acidity (pH), TSS (brix)0, total sugars (%), total fruits per plant, fruit set (%), yield per tree (Kg), length of fruit (cm), fruit width (mm), total number of seeds per fruit and peel thickness (mm) were studied. The collected data was analyzed statistically by Using STATISTIX 8.1 According to results, T6 (Nitrogen @1.5%) gave best results in terms of reducing sugars, TSS/Brix (0), total sugars (%), fruit set (%), yield per tree (Kg), fruit length (cm), fruit width (mm), number of seeds per fruit and peel thickness (mm). The minimum acidity (pH) was recorded in T5 (Nitrogen @1%) and T4 (FeSO4 @0.5%). While the maximum number of fruits per plant were recorded in T4 (FeSO4 @0.5%) then in T2 (ZnSO4 @0.5%). All the treatments gave good result as compare to T0 (control / no treatment) while T6 (Nitrogen @1.5%) gave best results in maximum parameters observation. From the results it was concluded that foliar spray Nitrogen @1.5% can be used for enhancing the yield and fruit quality of Kinnow mandarin.

Bio-organic fertilizers can improve soil health and maintain microbial activity. The application of Aspergillus spp. can degrade organic matter, promote plant growth, and improve soil health by accelerating soil nutrients and biological activity. Previously, Aspergillus spp. has shown potential in phosphate solubilization and siderophore production. Still, a study gap remains, and focus has been placed on clarifying the impact of Aspergillus sp. AS2022 on soil microbial biomass and soil nutrient acceleration. For this purpose, a pot experiment was established with four different treatments: cow compost (CC), cow compost + AS2022 (CA), AS2022 (AS) strain only and control-only soil (CK). The amount of cow compost used was 180 mg N kg-1. Results revealed that inoculation of AS2022 with cow compost stimulated nitrogen mineralization and enhanced available nitrogen and accelerated the soil enzyme activities, which proposed that it could contribute to wheat crop production through the initial and later phases of plant growth. Although a single application of AS2022 enhances plant growth compared to the control, it might be the release of secondary metabolites. However, our short-term findings showed that the combined application of beneficial fungal strain AS2022 along cow compost was suitable culture for wheat crop production and improvement of soil quality through organic matter degradation and accelerating soil nutrients.

Spatial variability mapping of soil properties is essential to understand the differences among soils found in a geographical region for their better management. This study aimed at spatial variability mapping of selected soil properties of district Tando Allahyar, Sindh which is one of the most important districts of Sindh province. The results revealed that majority of soils (35.6%) had loamy slightly medium-textured type, including 30.8% silt loam, 3.8% loam and 1.0% silt, followed by clayey, fine-textured heavy type (27.9%), including 18.3% clay, 6.7% silty clay and 2.9% sandy clay. Soils with sandy, coarse-textured light type were 20.2%, including 16.3% sandy loam and 1.9% loamy sand and sand each. Soils with loamy, moderately medium-textured type were 16.3%, including 9.6% clay loam and 6.7% sandy clay loam, while silty clay loam soil texture was total missing. The EC ranged from 0.14 to 4.44 dS m-1 (mean: 0.69 dS m-1, mode: 0.42 dS m-1). Majority (91%) of soils had low (46%) to medium (45) level of salinity. Soil pH ranged from 6.2 to 8.6 (mean: 7.7, mode: 8.3). Majority of soils (84%) had either slightly (24%), medium (22%) or strongly alkaline (38%) soil pH. Interestingly, some soils (13%) had slightly acidic pH. Organic matter ranged from 0.10 to 1.6% (mean: 0.64%, mode: 0.17%). Majority (84%) of soils were deficient in organic matter. Soil ABDTPA-P ranged from 1.2 to 18.8 mg kg-1 (mean: 5.38 mg kg-1, mode: 2.4 mg kg-1). More than half (55%) of the soils had low P, while soils with marginal (14%) or adequate (31%) P were also present. Soil ABDTPA-K ranged from 31 to 376 mg kg-1 (mean: 154 mg kg-1, mode: 230 mg kg-1). Majority of soils (62%) had adequate K, while soils with marginal (28%) or low (11%) K were also found. Spatial variability mapping revealed the dominance of loam, sandy clay loam, sandy loam, silty clay and clay loam textures, medium > low and high > salinity, slightly to medium alkaline soils > strongly alkaline soils, low organic matter content, medium to adequate > low soil P, and adequate soil K.

Authors: Priya Vansh , Bais Prateek S. , Rastogi Amit , Shamim Rafat , Aggarwal Anil , Patro Abinash
Published: May 2023

Background and Aims:

Increased burden of diabetes in India has resulted in a spurt in the number of patients with diabetes posted for surgeries. The paucity of national guidelines can lead to marked practice variations in the peri-operative management of diabetes. This survey intends to discern current peri-operative practices among anesthesiologists working in medical colleges, tertiary care government, and private health care institutes of the country.

Material and Methods:

An anonymous online survey comprising of 25 closed-ended questions was conducted using Google Forms® and disseminated through social media, emails, and messaging platforms. The questionnaire dealt primarily with the peri-operative management of diabetes in patients scheduled for elective surgery. The survey was conducted over a period of 1 month and targeted anesthesia resident trainees with more than 1-year experience, senior residents, and consultants working in India.

Results:

Statistically significant difference was observed between the three types of health facilities with respect to prior evaluation for diabetes (P = 0.007), prioritizing operative list (P = 0.006), hospital encouragement of day care surgery (P < 0.001), glycated hemoglobin level (HbA1c) level >8.5 for postponement of surgery (P < 0.05), insulin infusion preference (P < 0.001), hourly intra-operatively capillary blood glucose (CBG) assessment (P = 0.021), and avoiding peri-operative use of Ringer’s lactate (RL) (P = 0.025).

Conclusion:

This survey primarily highlights the lack of prioritizing the operative list, early discontinuation of metformin, and reduced tendency to consider diabetics for day care surgeries.

Statement of problem: Evaluating the effectiveness of the management of Olfactory Dysfunction (OD) has been limited by a paucity of high-quality randomised and/or controlled trials. A major barrier is heterogeneity of outcomes in such studies. Core outcome sets (COS) –standardized sets of outcomes that should be measured/reported as determined by consensus—would help overcome this problem and facilitate future meta-analyses and/or systematic reviews (SRs). We set out to develop a COS for interventions for patients with OD. Methods: A long-list of potential outcomes was identified by a steering group utilising a literature review, thematic analysis of a wide range of stakeholders’ views and systematic analysis of currently available Patient Reported Outcome Measures (PROMs). A subsequent e-Delphi process allowed patients and healthcare practitioners to individually rate the outcomes in terms of importance on a 9-point Likert scale. Results: After 2 rounds of the iterative eDelphi process, the initial outcomes were distilled down to a final COS including subjective questions (visual analogue scores, quantitative and qualitative), quality of life measures, psychophysical testing of smell, baseline psychophysical testing of taste, and presence of side effects along with the investigational medicine/device and patient’s symptom log. Conclusions: Inclusion of these core outcomes in future trials will increase the value of research on clinical interventions for OD. We include recommendations regarding the outcomes that should be measured, although future work will be required to further develop and revalidate existing outcome measures.

Salsalate Improves Postprandial Glycemic and Some Lipid Responses in Persons With Tetraplegia: A Randomized Clinical Pilot Trial With Crossover Design
Authors: Kressler Jochen , Mendez Armando , Betancourt Luisa , Nash Mark
Published: May 2023

Objectives

To investigate the effects of salsalate on fasting and postprandial (PP) glycemic, lipidemic, and inflammatory responses in persons with tetraplegia.

Methods

This study was a randomized, double-blind, cross-over design. It was conducted at a university laboratory. Ten males aged 25 to 50 years with SCI at C5-8 levels for ≥1 year underwent 1 month of placebo and salsalate (4 g/day) treatment. Blood samples were drawn before and 4 hours after breakfast and lunch fast-food meal consumption.

Results

Descriptive statistics indicate that fasting and PP glucose values were reduced with salsalate (pre-post mean difference, 4 ± 5 mg/dL and 8 ± 8 mg/dL, respectively) but largely unchanged with placebo (0 ± 6 mg/dL and -0 ± 7 mg/dL, respectively). Insulin responses were generally reciprocal to glucose, however less pronounced. Fasting free fatty acids were significantly reduced with salsalate (191 ± 216 mg/dL, p = .021) but not placebo (-46 ± 116 mg/dL, p = .878). Results for triglycerides were similar (25 ± 34 mg/dL, p =.045, and 7 ± 29 mg/dL, p = .464). Fasting low-density lipoprotein (LDL) levels were higher after salsalate (-10 ± 12 mg/dL, p = .025) but not placebo (2 ± 9 mg/dL, p = .403) treatment. Inflammatory markers were largely unchanged.

Conclusion

In this pilot trial, descriptive values indicate that salsalate decreased fasting and PP glucose response to fast-food meal challenge at regular intervals in persons with tetraplegia. Positive effects were also seen for some lipid but not for inflammatory response markers. Given the relatively “healthy” metabolic profiles of the participants, it is possible that salsalate's effects may be greater and more consistent in people with less favorable metabolic milieus.

Students act as followers and passive recipients of the activities carried out. Therefore, it is necessary to apply a learning model that involves students in the teaching and learning process, so that they can develop the potential of each student independently. One of them is the problem posing learning model. The problem posing learning model is a learning model that requires students to compose their own questions or solve a problem. The purpose of this research is to find out whether there are differences in the mathematics learning outcomes of students who follow the problem posing learning model, whether there is an interaction effect between the application of the problem posing learning model and the belief in mathematics on learning outcomes, whether there are differences in learning outcomes between students who follow the problem posing learning model and students who follow conventional learning models in groups of students who have high mathematical confidence and low mathematical confidence. The results of hypothesis testing using two-way ANOVA. Based on the results of the research and data analysis, it was found that 1) there were differences in the learning outcomes of students who took the problem posing learning model and those who followed the conventional learning model. 2) There is an interaction effect between the application of problem posing learning models and mathematical beliefs on learning outcomes. 3) There are differences in the learning outcomes of students who follow the problem posing learning model with students who follow conventional learning models in groups of students who have high mathematical confidence. 4) There is no difference in the learning outcomes of students who follow the problem posing learning model with students who follow the conventional learning model in groups of students who have low mathematical confidence.

PT. XYZ is a multinational company manufactured semi-finished raw materials of cocoa commodities. The continuity of the production process is very imporant in terms of ensuring that customers will receive a timely supply according to the schedule. The technology for processing the cocoa product in general is still produced by the oversea companies, especially from European countries. To support the production process, the procurement of spare parts for routine maintenance (preventive maintenance) plays an imporant role. Because procurement of the spare parts still involves the original equipment manufacturer company directly from the oversea company, the determination of incoterms will affect impor costs which will be borne by the seller or buyer depend on the agreement. These costs will also consider risk handling of impored the goods. Based on data obtained, the determination of incoterms at PT. XYZ in procuring spare parts for production machines still follows the incoterms proposed by the seller along with the submission of the price of spare parts. In this research, an analysis will be carried out on selecting the right incoterms based on incoterms 2020 covering aspects of cost and risk that can be used by PT. XYZ for making decisions to impor the spare parts in the next order.

On the Business Activity of Eustati Selveli in 1844
Authors: Goranchev Veselin
Published: May 2023

Abstract: This article presents information about the economic activity of the 19th century Tarnovo entrepreneur and public figure Eustati Selveli in 1844. During the year under review E. Selveli participated in at least two business structures. These were the trading companies “Hadji Mincho Hadji Tsachev and Company” and “Eustati Hadji N. Selveli and Company”. In the first, he worked together with Hadji Mincho Hadji Tsachev who was also the main shareholder in it, and in the second, with one of his earliest partners (most probably the earliest one) – Atanas Hadji Nikolaou. The information that the preserved documents provide on the general economic activity of E. Selvleli and Hadji Mincho in 1844 is rather scarce. Historical sources contain richer information on the general activity of E. Selveli and At. H. Nikolaou. The main source on the matter is the trade notebook of the partners. It was kept in Greek and covered the period 1842–1845. In this sense, the publication reveals more details on the activity of the trading company “Eustati Hadji N. Selveli and company” and more specifically presents information on the main business partners of the associates; the goods they traded in; their volume and prices; the monetary units they used in their business activity and their equivalent in grosh (the local coin at the time); the roads that the goods were transported, etc.

Kohler's Disease Case Report: Treatment with Regenerative Distraction Arthroplasty Technology
Authors: Slater Gordon
Published: May 2023

Kohler’s disease is a rare condition which in most cases responds to non-operative management. This report presents an unusual case where the thinning of the navicular resulted in a symptomatic pathological fracture. The patient was treated initially by Open Reduction and Internal Fixation (ORIF). The fracture united and the patient’s symptoms initially resolved. Three years later, symptomatic peri-navicular arthritis developed which was treated by distraction arthroplasty leading to symptom resolution. This case presents a novel solution which otherwise would have resulted in a complex midfoot fusion in a young patient. The methodology demonstrates the utility of new technological advances in joint regenerative technology.
Cutaneous Loxoscelism On 5 Moroccan Cases
Authors: Chhiti Sokaina
Published: May 2023

Introduction: Loxoscelism is an under-diagnosed condition due to lack of awareness among practitioners. It is a serious form of araneism that can be strictly cutaneous with variable clinical aspects that can be deadly.

Materials and methods: Five cases were collected over a period of 3 years presenting with envenomation by a supposed spider bite highly suggestive of cutaneous loxoscelism.

Results: We collected five cases of post-spider bite envenomation with an average age of 45 years, predominantly female, of rural origin. The bite occurred in the summer in all cases. The average time to consultation was 2 days. Four patients had felt and located the spider nearby. Two patients had an erysipéloïde placard centred by a necrotic ulceration, while one had post-bite erythema multiforme, one had acute exanthematous pustulosis and one had acute urticaria. Biological tests were normal in all cases. Antihistamines and dermocorticoids were prescribed.

Discussion: This type of envenomation is common in the summer months and in rural areas, with a clear female predominance. It is generally induced by the venom of spiders of the sicariidae family and of the Loxosceles genus. The diagnosis is based on a combination of epidemiological, clinical and biological evidence.

Conclusion: Envenomation by spider bites has been little reported in Morocco until now. This rare cause of necrosis, skin rash deserves to be known by practitioners for an adequate management.
Etiology Understanding Is the Core of Skeletal Diagnosis
Authors: Kaissi Ali Al
Published: May 2023

Background: The term idiopathic is a non-specific disease label, which fails account for proper etiological understanding. The frequent usage of the term idiopathic may indicate clinical incompetence. We describe a number of patients from our practice with a history of complex bone disorders who were falsely given the term idiopathic by other Institutes. The sole tool used by other Institutes to conclude osteoporosis as a diagnosis is the bone mineral density.

Material and Methods: Two Austrian families and one unrelated adult female patient (total number of 12 subjects) have been referred to our department with referral letters confirming the diagnosis of idiopathic osteoporosis. All patients manifested a diverse constellation of skeletal deformities. In all these patients, regular courses of anti-resorptive treatment plus calcium and vitamin D supplements. These have been excessively prescribed.

Results: Our diagnostic process which is based heavily on detailed clinical and radiological phenotypic characterizations, we refuted the diagnosis of idiopathic osteoporosis for all patients because of the clear-cut clinical features. For the first family, we suggested the diagnosis of a novel type of mucopolysaccharidosis (the genetic results confirmed the diagnosis of a novel subtype of mucopolysaccharidosis (through the identification of arylsulfatase K ARSK). For the second family which has been subjected to a lengthy useless investigation for almost more than a decade, we refuted the diagnosis of idiopathic osteoporosis and the whole exome sequencing was consistent with the phenotypic diagnosis Nasu-Hakola disease (heterozygous missense mutations in TYROBP gene). The other unrelated 42-year-old- female patient was correctly diagnosed with Nasu-Hakola disease.

Conclusion: The objective of this study is to minimize and suppress the usage of the term idiopathic. It has been imperative to understand the sequence of pathological events that occurred in these families. The core for diagnosis is the etiological understanding, which stemmed from professional conscientiousness. Patients underwent misdiagnosis of idiopathic osteoporosis and were treated extensively with anti-resorptive agents, calcium supplements and vitamin D. Strikingly, these medications resulted in a combination of serious cranial and cerebral lesions because of massive pathological calcifications. Imaging analysis via conventional radiographs, MRI and CT scan showed massive calcifications of the cranial sutures, inter-clinoid ligaments and hyper-calcification of the skull base. Sadly speaking, early onset dementia emerged in connection with sclerosing leukoencephalopathy. We believe that the exogenous toxic effects of the huge amounts of bone supplements consumed by these patients enhanced the pre-existing metabolic bone and cerebral disorders. Our findings can ameliorate the etiological understanding of early onset dementia and other correlated cranial and skeletal lesions.
