Abstract
The propagation of energetic charged particles and cosmic rays in magnetized thermal plasma is focused. We consider a four-fluid system that consists of thermal plasma, cosmic rays, and two opposite propagating Alfvén waves to investigate the dynamics and energy exchange mechanisms of the system. Additionally, cosmic rays diffusion within the plasma is considered along the magnetic field lines whereas neglected the cross field line diffusion effects. This study is important for understanding of pressure gradients and their impact on the feedback in astrophysical environment. Over the last few decades, this problem becomes important when we discuss the interaction of cosmic rays with plasma in space, such as interstellar clouds or interstellar medium.

Abstract
Abstract
Introduction
Ageing is associated with multimorbidity, polypharmacy and medication-related harm (MRH). A 2013 systematic review reported only one study of medication errors (MEs) in older Egyptian patients. Our study investigated MRH (adverse drug reactions (ADR), drug errors, and non-adherence) in older Egyptian adults after hospital-discharge.
Methods
Between 2018 and 2020, we recruited 400 Egyptian patients, aged ≥60 years on discharge from Geriatrics and Internal Medicine wards from 3 hospitals, and followed them up for 8 weeks. Study procedures adopted a modified PRIME trial methodology (1).
Results
The average age of study participants was 71 (range 60 to 93, SD +/- 6.29) years with 53% females. In the cohort of 325 patients completing follow up, MRH occurred in 99 patients (incidence of 30.5%), with 5 patients (5.1%) experiencing a fatal MRH. Almost two thirds (65.7%) of MRH events were secondary to ADRs, 2 % related to non-adherence, 18.2 % due to both ADR and non-adherence, and 14% related to MEs. Multivariate logistic regression analysis showed that non-adherence (p-value 0.000, OR- 95% CI: 36.029), inappropriate prescription using Beer’s criteria (p 0.000, OR- 95% CI: 6.589), length of stay >7days (p 0.001, OR- 95% CI: 6.176), presence of Ischaemic Heart Disease (IHD) (p 0.000,OR- 95% CI: 5.695), Platelets count ≤ 245X 109/L (p 0.021, OR- 95% CI: 2.640), and dementia medications (p 0.017, OR- 95% CI: 4.616) were all significantly associated with MRH.
Conclusions
Medication-related harm in older Egyptian adults is common after hospital discharge. An integrated care pathway is required targeting high-risk older patients.

Apatitic calcium phosphate /montmorillonite nano-biocomposite: in-situ synthesis, characterization and dissolution properties. Heliyon 2022; 8:e10042.

Abstract
Recently, calcium phosphate/montmorillonite composites have received attention as a synthetic bone substitutes. In this study, apatitic calcium phosphate/Montmorillonite nano-biocomposites were in-situ synthesized at 22 °C by reaction between calcium hydroxide and orthophosphoric acid in the presence of different contents of montmorillonite (MNa). Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM) and Brunauer–Emmett–Teller (BET) surface areas were used to characterize the prepared powders. The XRD results show that the composites prepared with 2 and 5 wt% MNa and sintered at 900 °C, show the formation of hydroxyapatite (HAP) structure, whereas that prepared with 10 wt% MNa leads to the formation of β-tricalcium phosphate (β-TCP) structure. The HAP structure decomposes at 1000 °C and leads to the formation of biocomposite containing HAP, β and α-TCP. However, β-TCP composites show thermal stability. FTIR and structural refinement results show the incorporation of clay ions into the apatitic structure causing changes in the crystal structure of the formed calcium phosphate phases. The changes in the composition and structure lead to an increase in the dissolution rate of HAP and a decrease in that of β-TCP.

Abstract
Phytoremediation is an ecofriendly technique to clean heavy metals from contaminated soil by the use of high biomass producing plant species. Chelators can help to improve this biological technique by increasing metal solubility. Therefore, a pot experiment was conducted to determine the effect of the chelators EDTA and citric acid (CA) in phytoremediation of Ni contaminated soil by using Brassica napus (canola). Two cultivars of B. napus, Con-II (tolerant) and Oscar (sensitive), were selected after screening and exposed to NiSO4 at 30 ppm at the time of sowing. CA (10 mM) and EDTA (1.5 mM) were applied either alone or in combination with each other after two weeks of Ni treatments. Different parameters like morpho-physiological and biochemical data were recorded after 15 days of chelate application. The results highlighted the successful use of chelating agents (CA and EDTA) not only to ameliorate Ni stress but also to enhance Ni accumulation which is prerequisite for phytoremediation. The basal application of 10 mMCA and 1.5 mM EDTA concentration proved to be effective for the growth of plants. The combination of chelating agents failed to show any synergistic effects.

Abstract
Introduction Nations thorughout the world are imposing mandatory quarantine on those entering the country. While such measures may be effective in reducing the importation of COVID-19, the mental health implications remain unclear. Objectives This study sought to assess mental well-being and factors associated with changes in mental health in individuals subject to mandatory quarantine following travel. Methods Travellers arriving at a large urban international airport completed online questionnaires on arrival and days 7 and 14 of mandated quarantine. Questionnaire items such as travel history, mental health, attitudes towards COVID-19, and protection behaviours were drawn from the World Health Organization Survey Tool for COVID-19. Results There was a clinically significant decline in mental health over the course of quarantine among the 10,965 eligible participants. Poor mental health was reported by 5.1% of participants on arrival and 26% on day 7 of quarantine. Factors associated with greater decline in mental health were younger age, female gender, negative views towards quarantine measures, and engaging in fewer COVID-19 prevention behaviours. Conclusions While the widespread use of quarantine may be effective in limiting the spread of COVID-19, the mental health implications are profound and have largely been ignored in public policy decision-making. Psychiatry has a role to play in contributing to the public policy debate to ensure that all aspects of health and well-being are reflected in decisions to isolate people from others. Disclosure No significant relationships.

Abstract
In view of the emerging population trends and that wheat crop is the major unequivocally recognized conduit towards addressing the food security challenges of 2050 this discourse embraces various research options that are viewed as possible solutions toward delivering those targets for providing nutritious food and meeting the aspirations that policy setters have debated on the subject for decades. The underlying strength for achieving these targets will require concerted efforts from plant researchers that are well integrated within effectively harnessing and utilizing prevalent genetic diversity of the wide array of alleles in a holistic pro‐active manner. We argue that the purists of basic and strategic research dimensions need to be thoughtfully defined, so that the vital target of delivering the “applied” gains are only realized from the outputs on farmer’s fields and measured by tons per hectare. In this quest, the pre‐breeding disciplines “classical mode” and its recently surfaced “modified sense” are pivotal, where within the former facet “tissue culture” (TC)/artificial culturing is embodied integrally. Taken for granted, TC has been the backbone of all wide hybridization studies and has made an enormous impact on the agricultural landscape spanning over the last six decades. With its intervention significant generic and specific incompatibilities have been overcome as well as allowing researchers to exploit the protocols for adding efficiency to breeding programs, facilitate operational technologies in running breeding programs and development of unique genetic stocks that preserve valuable allelic richness in user friendly forms for future free germplasmusage in global/private domains of plant improvement ventures.Plant Tissue Cult. & Biotech. 27(1): 89-140, 2017 (June)

Abstract
Gall midges (Diptera: Cecidomyiidae) damage mango by feeding on flowers and fruit tissues, inducing galls on leaves, and providing inoculums of anthracnose. Dasineura amaramanjarae Grover and Procontarinia mangiferae (Felt), two gall midges that damage flowers in all mango-growing areas of the world, have recently been recorded in Pakistan, and studies were conducted in 2011 and 2012 on the within-tree and orchard distribution patterns and cultivar preference of both species in Pakistan at one location (Rahim Yar Khan). Both gall midge species were found on all mango cultivars examined (Chaunsa, Fajri, Dusehri, Surkha, Sindhri, and Anwar Ratul), with the most damage occurring to Surkha and Dusehri. Research on midge distribution patterns in different parts of mango orchards (central, southern, northern, eastern, and western sides) showed these species to be found in all areas, with the greatest numbers in the central and southern regions. In addition, both species were most abundant on the lower parts of the mango tree canopy.

Abstract
AIM To compare HbA1c and fasting plasma glucose assessment, with the 2-h oral glucose tolerance test as reference, in screening for diabetes in people with turberculosis. METHODS Individuals (N=268) with newly diagnosed smear-positive tuberculosis were screened for diabetes at a tertiary hospital in Lahore, Pakistan. Diabetes diagnosis was based on WHO criteria: thresholds were ≥48 mmol/mol (≥6.5%) for HbA1c and ≥7.0mmol/l for fasting plasma glucose. RESULTS The proportion of participants diagnosed with diabetes was 4.9% (n =13) by oral glucose tolerance test, while 11.9% (n =32) and 14.6% (n =39) were diagnosed with diabetes using HbA1c and fasting plasma glucose criteria, respectively. The area under the receiver-operating characteristic curve was 0.79 (95% CI 0.64 to 0.94) for HbA1c and 0.61 (95% CI 0.50 to 0.73) for fasting plasma glucose, with a borderline significant difference between the two tests (P=0.07). CONCLUSIONS HbA1c and fasting plasma glucose performed equally in terms of diagnosing new diabetes cases in individuals with tuberculosis, but the proportion of participants falsely classified as positive was higher for fasting plasma glucose. This may be explained by acute blood glucose fluctuations when using fasting plasma glucose. HbA1c may be a more reliable test in individuals with transient hyperglycaemia.

Abstract
In this work, we report the design configuration and the performance of the hybrid Gas Electron Multiplier (GEM) detector. In order to make the detector sensitive to thermal neutrons, the forward electrode of the GEM has been coated with the enriched boron-10 material, which works as a neutron converter. A total of 5×5cm2 configuration of GEM has been used for thermal neutron studies. The response of the detector has been estimated via using GEANT4 MC code with two different physics lists. Using the QGSP_BIC_HP physics list, the neutron detection efficiency was determined to be about 3%, while with QGSP_BERT_HP physics list the efficiency was around 2.5%, at the incident thermal neutron energies of 25meV. The higher response of the detector proves that GEM-coated with boron converter improves the efficiency for thermal neutrons detection.

Abstract
We report a case of a 54 year old male who presented with abdominal pain and hematemesis. After thorough workup, a laparotomy was done. It revealed an ante grade intussusception in the afferent limb of a gastrojejunostomy, which was done in 1978 presumably for peptic ulcer disease. In an attempt to find if such cases are still reported and under what circumstances, a Pub med search using: (intussusception) and (gastrojejunostomy or gastroentorostomy) was done and 170 publications were retrieved. Relevant articles were studied and discussed in this case report. DOI: http://dx.doi.org/10.3329/pulse.v6i1-2.20348 Pulse Vol.6 January-December 2013 p.41-43

Abstract
Background The abdominal cocoon syndrome was first described as a rare condition where part of or the whole small bowel is encased within a fibrous membrane. Idiopathic sclerosing encapsulating peritonitis (or abdominal cocoon) is a rare cause of small bowel obstruction, especially in adult population. Diagnosis is usually incidental at laparotomy. But preoperative diagnosis can be made. Case presentation This report is of a 27-year-old Bangladeshi male who presented with increasing abdominal pain and features of subacute intestinal obstruction. He had a history appendicectomy 2 months back through grid iron incision in a peripheral hospital. Pre-operative work-up did not reveal a sac like structure encasing small intestinal loops. At computed tomography of the abdomen and pelvis, a huge cystic structure was seen encasing loops of small bowel. At laparotomy, a fibrous capsule was revealed, in which small bowel loops were encased, with the presence of interloop adhesions. A diagnosis of primary abdominal cocoon was established and extensive adhesiolysis was performed. The patient had an uneventful recovery and follow-up. No evidence of Kochs noted in the abdomen or on histopathology of tissue sent for examination. Conclusion Abdominal cocoon is a rare cause of small bowel obstruction, but should be suspected especially in cases with attacks of non strangulating obstruction in the same individual. A high index of clinical suspicion may be generated by the recurrent character of small bowel obstruction. Clinicians must rigorously pursue a preoperative diagnosis. The overall prognosis is satisfactory. DOI: http://dx.doi.org/10.3329/pulse.v5i2.20269 Pulse Vol.5 July 2011 p.61-64

Abstract
Salinity reduces plant growth and yield by affecting morphological and physiological processes. To alleviate the harmful effects of salt stress various approaches involving plant hormones are used. In this study several parameters involving the measurement of cell membrane injury were used to observe whether stress tolerance could be enhanced in Chinese cabbage (B. oleracea capitata L. Chinensis group) by soaking the seeds for 10 h in distilled water (control), or in 100, 150 or 200 mg l−1 gibberellic acid (GA3). The NaCl concentrations were 0 (control), 50, 100 and 150 mM. Seed treated with GA3 showed increased water uptake and decreased electrolyte leakage as compared to that of distilled water-primed seeds even 24 h after soaking under control conditions. Seed priming with GA3 increased the final germination and the germination rate (1/t50, where t50 is the time to 50% germination) under salt stress conditions. Seed priming also alleviated the harmful effect of salt stress on cabbage in terms of fresh and dry weights. Leaf area was higher in plants raised from seeds primed with the higher GA3 concentrations as compared with those raised from seeds treated with distilled water under control conditions (without NaCl) or at 50 mM NaCl stress. The chlorophyll content increased with the NaCl concentration, especially in plants grown from seeds primed with GA3. Plants grown from GA3-primed seeds also suffered lower cellular injury both under control conditions and under NaCl stress.

Abstract
Salinity induced inhibition in germination and early stages of cabbage (Brassica oleracea capitata L.) [two varieties (autumn cabbage and spring cabbage)] were measured in response to increasing NaCl concentration. The salinity (NaCl) concentrations in solution were 0 (control), 4.7, 9.4 and 14.1 dS m(-1). Different concentrations of salt stress had considerable effect on germination, germination rate (1/t50, where t50 is the time to 50% of germination), root and shoot lengths, root, shoot and plant fresh weight of cabbage. Final germination in cabbage (autumn cabbage and spring cabbage) showed significant inhibition with increasing salt stress up to 14.1 dS m(-1) NaCl. The required time for germination increased with increasing concentration of salt. The seedling growth was strongly inhibited by all salt levels, particularly at 14.1 dS m(-1). Furthermore Root growth was more affected then shoots growth by salt stress. Fresh weights of root, shoot and plant were also severely affected by different salinity treatments. Linear regression revealed a significant negative relationship between salinity and final germination, germination rate, root and shoot lengths and fresh weights of roots, shoots and plants.
