درد اک رنگ ہے قرار نما

درد اک رنگ ہے قرار نما
اور ہے رنگ اک ہزار نما

لب ہلے اس کے اور دل میرا
کھینچتا جائے ہے شکار نما

اس ادا پہ ہیں جان و دل قربان
دشمنِ جاں ہوئے ہیں یار نما

اب خزائوں سے کیا خطر مجھ کو
اس کی اک اک ادا بہار نما

عالم اپنا ہے عالمِ دیگر
شعر میرا ہے اک ہزار نما

زندگانی سکوتِ شب ہے فضاؔ
اور سحر لائی ہے قرار نما

Factors Related to the Implementation of Evidenced-based Practice (EBP) of Nursing Staffing Levels in Hospitals: A Literature Review

The implementation of Evidenced-based practice (EBP) was one of the factors in increasing the quality of health services as an ideal problem-solving approach. The ability of nurses to appliance EBP was influenced by many factors, not only on individual nurses consisting by the support of unit leader and colleague. The purpose of this study was to determine the factors associated with the implementation of EBP at the care room level establishing on the support of coworkers and nursing managers. This writing used a literature review study, from several databases namely PubMed, ProQuest, Google Scholar, and ScienceDirect with a limitation of the last 5 years. 17 journals met the inclusion criteria and the results of a literature review study show: eight journals conclude that the support of colleagues and authority in changing practices affects the implementation of EBP, 13 journals concluded the role of managerial nurses affects the implementation of EBP consisting of leadership support and mentorship including the lack of knowledge and skills of nursing leaders regarding EBP. Data from the collected and identified literature study clearly showed that EBP knowledge and skills of nursing leaders related to EBP are important factors in increasing the implementation of EBP but co-worker factors can be a supporter and also an obstacle to the implementation of EBP if it is not well managed.

Biochemical Characterization of Glucans from Mushrooms and Their Application As Green Matrix for Nano-Particles

The use of antimicrobial drugs has decreased the frequency of infectious ailments. But their widespread use has generated drug-resistant microbes, so there is need to develop new rapid acting antibiotics with less side effects. The silver nanoparticles have been recognized as efficient broad spectrum antimicrobial agents. It uses mushroom glucans as reducing and capping agent to decline its toxicity. The present study was primarily, on the nutritional, biochemical and nutraceutical characterization of mushroom and ultimately, on the green synthesis of silver nano-particles with mushroom glucans and then characterization, antimicrobial and biochemical analysis through in vitro and in vivo studies. The four different Pleurotus spps. including P1: Pleurotus ostreatus, P3: Pleurotus sajor-caju, P6: Pleurotus sapidus and P8: Pleurotus columbinus were collected from mushroom culture bank of Medicinal Mushroom Laboratory, Institute of Horticultural Sciences, University of Agriculture, Faisalabad, Pakistan. Proximate analysis of the selected mushrooms depicted the protein (19.07-30.15%), ash (2.1-9.14%), carbohydrate (65.66-82.47%) and fiber contents (38.5-46.3%) were present in significant amounts whereas fats (1.04-6.01%) were in low concentration. All the mushrooms showed potential total phenolic contents (TPC), total flavonoid contents (TFC), DPPH radical scavenging and reducing properties. Selected mushrooms showed DNA protection against H2O2, by use of calf thymus (ctDNA). A moderate antimicrobial potential exhibited by all mushrooms against selected bacterial (E. coli, P. multocida, B. subtilis and S. aureus) and fungal species (A. niger, A. flavus, F. solani and H. maydis). Fatty acids profile by Gas chrometography-Mass spectroscopy (GC-MS) showed that the unsaturated fatty acids were more prevalent over the saturated fatty acids in targeted Pleurotus spps. Quantitative protein analysis depicted h i g h concentration of proteins (33.47-45.78 mg/g) in selected Pleurotus spps. High performance liquid chromatography (HPLC) analysis expressed variable concentration of sugars and organic acids present in the Pleurotus spps. Quantitative ascorbic acid analysis depicted that they were significantly higher (4.90-6.97 mg/g) in chosen Pleurotus spps. High performance liquid chromatography (HPLC) analysis of α-tocopherols and β-carotenes showed that they were present in targeted Pleurotus spps. Macro and micronutrients studies showed that all four Pleurotus spps. have minerals [Na (19.09-39.2 mg/100g) and K (4.84-11.98 mg/100g)] micronutrients [Ca (1.33-11 mg/100g), Mg (1.4-2.1 mg/100g) and P (2.1-4.3 mg/100g)] and xxv trace elements [Cu (10.2-15.42 mg/100g), Mn (2.1-7.4 mg/100g), Zn (37.5-54.6 mg/100g) and Fe (12.1-15.2 mg/100g)] while all were deficient of heavy metals like Pb. Green synthesis of silver nano-particles performed by glucans from selected Pleurotus spps. Extracted glucan and synthesized Glucan-AgNPs confirmed by Ultraviolet-Visible (UV-Vis) spectra. Size of Glucan-AgNPs determined by Dynamic light scattering. The Glucans characterized by Fourier transformation infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM) and X-ray diffraction (XRD) and Glucan-AgNPs were characterized by FT-IR, Scanning electron microscopy-Energy dispersive spectroscopy (SEM-EDS), Transmission electron microscopy (TEM) and XRD. In vitro studies showed that Glucan- AgNPs revealed excellent antimicrobial, biofilm inhibition and anti-cytotoxic potentials. In vivo studies performed on adult albino rats. The glucan-AgNPs significantly restored the physical (Temperature), hematological (Total leukocyte count, neutrophil (%age) count and ESR) and biochemical (C-reactive proteins) parameters elevated after induction of infection. Histological examination revealed that there was no deposition of silver in small intestine, skin, liver and kidney.
