Maqbool Amir,Wachkoo Aijaz Ahmad,Yatoo Suhaib Firdous,Skevington Jeffrey H.,van Steenis Jeroen 한국응용곤충학회 2024 Journal of Asia-Pacific Entomology Vol.27 No.2

The genus Spilomyia (Insecta, Diptera, Syrphidae) consists of 39 species worldwide. One species previously listed from South Asia as Spilomyia manicata (Rondani, 1865), is herein described as a new species, Spilomyia recta van Steenis, Maqbool & Wachkoo sp. n. The new taxon represents the only valid species of Spilomyia from India and Pakistan and the third species known from Afghanistan and thus occurring in both the Palaearctic and Oriental region. Morphologically it is similar to the European species Spilomyia manicata, however based on the features of the male genitalia and molecular COI data the species is more closely related with S. diophthalma. Both morphological and molecular characteristics clearly separate these three species. Descriptions, diagnoses, high quality images, and phylogenetic relationships are presented. http://zoobank.org/urn:lsid:zoobank.org:pub :78A9D482-468F-41EB-B602-D854AE159327.

Maqbool, Mudasir,Zehravi, Mehrukh,Maqbool, Rubeena,Ara, Irfat Cellmed Orthocellular Medicine and Pharmaceutical 2021 셀메드 (CellMed) Vol.11 No.2

Background: ADRs (adverse drug reactions) are becoming a vital aspect of patient care and assessment. ADRs account for about 2% of all hospitalizations, according to the incidence rate. Medications with a narrow therapeutic index need ADR control rather than others. ADR research is required to determine the prevalence of ADRs in medical inpatients, estimate the impact of ADRs to hospital admissions, classify the types of ADRs found, identify possibly contributing risk factors, as well as estimate the costs of ADRs in terms of ADR-related excess stay in the hospital. For several years, theophylline has been used to treat asthma and chronic obstructive pulmonary disease (COPD). Theophylline-related adverse events (ADRs) were found to be 4.71 percent of the time, with nausea, anorexia (loss of appetite), and palpitation being the most common. Objective: The main objective of the study was to study adverse drug reactions in pulmonary medicine department of a Tertiary care hospital, Srinagar, Jammu & Kashmir, India. Methodology: For an eight-month period, a prospective, descriptive, cross-sectional study was conducted in the pulmonary medicine department of a Tertiary care hospital in Srinagar, Jammu & Kashmir, India. ADRs that occurred in the ward were closely tracked, and the collected reports were analyzed for demographic profile, type of ADRs, ADR occurrence and drug causing ADR, severity assessment, and ADR management. Results: During the study period, 420 patients' records were obtained from the pulmonary medicine department of a Tertiary care hospital. ADRs were registered in 60 of the patients. The demographics of ADR patients were analyzed, and it was discovered that the prevalence of ADR was highest in the age group of 50-59 years (21 out of 60) and lowest in the age group of <=19 years. The therapeutic drug groups most often involved in ADRs were investigated. The most common culprits among the medications are first-line TB drugs, which account for 21(35%) ADRs, corticosteroids, which account for 9 (15%) ADRs and other drugs used for different indications, such as ipratropium, furosemide, tramadol, and so on, which account for 30 (50%) ADRs. Hepatitis, loss of appetite, nausea, and vertigo were the most widely recorded ADRs in this study. Conclusion: ADRs are more prevalent in the elderly, and first-line TB drugs are more often implicated. The majority of the reactions were moderate. As a result, early identification, assessment, and control of ADRs are critical for reducing patient harm and improving public health.

An Overview about Treatment of Gestational Diabetes Mellitus: A Short Communication

Mudasir Maqbool,Mehrukh Zehravi,Rubeena Maqbool,Irfat Ara 셀메드 세포교정의약학회 2021 셀메드 (CellMed) Vol.11 No.3

Gestational diabetes mellitus (GDM) has become one of the major public health problems for both mothers and children globally. Internationally, the frequency of excess weight and obesity has risen dramatically in women of childbearing age. There seems to be a greater risk of having GDM in overweight or obese women, resulting in problems during pregnancy, birth and neonatal development. Hospital management is a problem for obese pregnant females with GDM and places extra burdens on the healthcare sector. GDM can result in possible risks to the wellbeing of the mother, fetus, and infant, as well as clinically significant negative effects on the mental health of the mother. For females and their developing babies, diabetes may cause problems during pregnancy. Unsatisfactory diabetes control enhances the risk of complications and other birth related issues during pregnancy. It may also cause a woman to suffer severe complications. Numerous maternal and fetal effects are associated with GDM and multiple detection and management methods are also pursued globally in order to reduce the burden of health. An overview of gestational diabetes treatment is given in this review.

기존의 연구들은 기업의 가치를 결정하는 요인으로서 부채의 영향만을 주로 분석하는 데에 그쳤다. 이런 한계를 넘어서고자 시도된 본 연구는, 부채의 성격과 내역 및 그 결과와 같은 자본구조의 변인이 기업의 가치에 어떤 영향을 미치는지를 탐색하기 위한 목적의 계량분석이다. 연구대상으로는 파키스탄의 기업 전체 리스트의 70%나 되는 비중을 차지하고 있는 비재무적인 영역의 기업이 선정되었다. 그들 중에서 161개의 비재무적인 기업들로 구성된 표본 집단으로부터 자료를 수집해서 분석한 연구결과, 유동성의 자본구조 변인이 기업의 부채에 대한 결정에 미치는 영향이69%에 달하는 것으로 나타났다. 기업크기의 측면에서 총자산 이익률의 자본구조 변인은 29%의 영향력은 지니는 것으로 나왔다. 이들 연구결과는 기업의 재무결정이 최적인지 아닌지를 평가하는 재무담당자에게 유용한 정보가 될 것으로 보인다. This research endeavoured to explore two schemes of the literature of capital structure i. e. antecedents and consequences of debt borrowing on firm specific factors and their impact on firm"s value. Previous studies tried to investigate the impact of debt borrowings on firm value. However, integration of these two ideas is non-existing. This research fills such literature gap and explores the determinants of capital structure to know whether these financing decisions are optimal or not. Non-financial sector firms are 70%, of total firms listed on KSE. It selected proposed research panel data for 161 non-financial firms listed at KSE for 2007 to 2014 and analyzed all of them. Its results show that liquidity has 69% influences in making the decision regarding debt financing, that return on assets has 25% influences on financing decision regarding debt that CG index is negatively linked with debt ratio, and that ROA in terms of the size of a firm is impacted by 29%. And thus this research provides some useful information for managers to know whether their financing decision is optimal or not, and how to make their financing decisions.

Novel sulfation effect on low-temperature activity enhancement of CeO₂-added Sb-V₂O₅/TiO₂ catalyst for NH₃-SCR

Maqbool, M.S.,Pullur, A.K.,Ha, H.P. Elsevier 2014 Applied Catalysis B Vol.152 No.-

Sulfur dioxide (SO<SUB>2</SUB>) is considered as a poisoning gas for NH<SUB>3</SUB>-SCR catalysts under real time conditions. However, it has revealed an obvious beneficial effect on the activity of CeO<SUB>2</SUB> containing catalysts. Hereby we report the applied research in sulfation effect on low-temperature activity enhancement of CeO<SUB>2</SUB>-modified, Sb<SUB>2</SUB>O<SUB>3</SUB>-V<SUB>2</SUB>O<SUB>5</SUB>-TiO<SUB>2</SUB> catalyst system pretreated with SO<SUB>2</SUB> under oxidizing conditions at different temperatures for 2h. We have elucidated the real insights via nature-property relationships of the species formed at various SO<SUB>2</SUB> pretreatment temperatures (T=300, 400 and 500<SUP>o</SUP>C) with the help of advanced characterization techniques such as X-ray diffraction (XRD), temperature programmed reaction (NH<SUB>3</SUB>-TPD, NO-TPD and H<SUB>2</SUB>-TPR), BET surface area, scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS) and X-ray photoelectron spectroscopy (XPS). Our results indicated that SO<SUB>2</SUB> pre-treatment at 500<SUP>o</SUP>C led to the maximum favorable sulfation with cerium(III) sulfate as the major surface species.

Dielectric and Ferroelectric Properties of Nb Doped BNT-Based Relaxor Ferroelectrics

Maqbool, Adnan,Hussain, Ali,Malik, Rizwan Ahmed,Zaman, Arif,Song, Tae Kwon,Kim, Won-Jeong,Kim, Myong-Ho Materials Research Society of Korea 2015 한국재료학회지 Vol.25 No.7

The effects of Nb doping on the crystal structure, microstructure, and dielectric ferroelectric and piezoelectric properties of $(Bi_{0.5}Na_{0.5})_{0.935}Ba_{0.065}Ti_{(1-x)}Nb_xO_3-0.01SrZrO_3$ (BNBTNb-SZ, with ${\chi}=0$, 0.01 and 0.02) ceramics have been investigated. X-ray diffraction patterns revealed that all ceramics have a pure perovskite structure with tetragonal symmetry. The grain size of the ceramics slightly decreased and a change in grain morphology from square to spherical shape was observed in the Nb-doped samples. The maximum dielectric constant temperature ($T_m$) increases with increasing amount of Nb; however, ferroelectric-relaxor transition temperature ($T_{F-R}$) and maximum dielectric constant (${\varepsilon}_m$) values decrease gradually. Nb addition disrupted the polarization hysteresis loops of the BNBT-SZ ceramics by leading a reduction in the remnant polarization coercive field and piezoelectric constant.

본 연구는 파키스탄 카라치 증권거래소에 상장된 기업의 재무적인 의사결정에 영향을 미치는 요인은 무엇이며 또한 이러한 재무적인 의사결정이 적절한지를 연구하는 데 그 목적이 있다. 이러한 연구목적을 위해서 2003년부터 2014년 까지 금융회사, 파산회사, 신설회사, 자본잠식회사 등을 제외한 276개의 기업의 표본을 선택하여 실증분석을 실시하였다. 실증분석 결과에 의하면 이들 기업의 유동성, 고정자본비율, 감가상각비율, 판매액 증가율은 부채액과 음(-)의 관계가 있는 것으로 나타났고, 이와 반대로 기업규모는 부채액과 정(+)의 관계가 있는 것으로 나타났다. 아울러 2개의 더미변수를 이용하여 부채와 이윤과의 관계를 분석해 보았다. 규모가 크고 위험성이 적고 성장성이 큰 기업은 부채가 이윤에 큰 영향을 미치지 않고 있어서 이들 기업의 부채조달에 관한 의사결정은 비교적 적절하다고 할 수 있다. 이에 비해 규모가 작고 위험성이 크고 고정자본비율이 높고 감가상각비율이 낮고 성장성이 작은 기업은 부채가 이윤을 감소시키는 것으로 나타나고 있어 이들 기업의 부채조달에 관한 의사결정은 적절하지 않다고 할 수 있다. 본 연구의 이러한 결과는 재무적 의사결정을 하는 경영자들에게 유용한 정보를 제공할 것으로 판단된다. This study aims at finding out determinants of capital structure and consequences of financing decisions. In an effort to figure out what factors determine financing decision and what outcomes their decision brings forth in the Pakistani firms listed at KSE, it tried a quantitative analysis on 276 firms selected for the period of 2003 to 2014 after excluding financial firms, default firms, newly registered firms and firms with negative equity. Its study results say that liquidity, tangibility, non-debt tax shield and growth are negatively associated with debt financing, except only the factor of firm size. And they also reveal that debt borrowings negatively affect profits overall in all the condition, but that the impacts of debt borrowing by larger, low riskier and high growth firms are less negative than those by small size, high risk, high tangibility, less non-debt tax shield and low growth firms. This study thereupon gives some useful information to firm managers in making financial decision.
