4Review of Mg alloy corrosion rates显示文摘A review of the literature confirmed that the intrinsic corrosion rate of high-purity Mg as measured by weight-loss is 0.3mm/y in a concentrated chloride solution.Atmospheric corrosion of Mg alloys has produced corrosion rates of Mg-Al alloys an order of magnitude lower than the intrinsic corrosion rate of Mg in a concentrated chloride solution of 0.3 mm/y.The only successful strategy to produce a Mg alloy with a corrosion rate in a concentrated chloride solution substantially less than the intrinsic corrosion rate as measured by weight loss of Mg of 0.3 mm/y has been to improve the protectiveness of the corrosion product film.Andrej Atrens Zhiming Shi Syeda UMehreen Sean Johnston Guang-Ling Song Xianhua Chen Fusheng Pan 2020Journal of Magnesium and Alloys2020,8,4:5

6Mutant p53 promotes cell spreading and migration via ARHGAP44显示文摘The tumor suppressor p53 protein is either lost or mutated in about half of all human cancers.Loss of p53 function is well known to influence cell spreading,migration and invasion.While expression of mutant p53 is not equivalent to p53 loss,mutant p53 can acquire new functions to drive cell spreading and migration via different mechanisms.In our study,we found that mutant p53 significantly increased cell spreading and migration when comparing with p53-null cells.RNA-Seq analysis suggested that Rho GTPase activating protein 44(ARHGAP44) is a new target of mutant p53,which suppressed AKHGAP44 transcription.ARHGAP44 has GAP activity and catalyze GTP hydrolysis on Cdc42.Higher level of GTP-Cdc42 was correlated with increase expression of mutant p53 and reduced ARHGAP44.Importantly,wt-ARHGAP44 but not mutant ARHGAP44(R291A) suppressed mutant p53 mediated cell spreading and migration.Bioinformatics analysis indicated lower expression of ARHGAP44 in lung carcinoma compared with normal tissues,which was verified by RT-qPCR using specimens from patients.More interestingly,ARHGAP44 mRNA level was lower in tumors with mutant p53 than those with normal p53.Collectively,our results disclose a new mechanism by which mutant p53 stimulates cell spreading and migration.Jinjin Xu Jian Jiao Wei Xu Lei Ji Dongjie Jiang Shaofang Xie Syeda Kubra Xiaotao Li Junjiang Fu Jianru Xiao Bianhong Zhang 2017Science China(Life Sciences)2017,60,9:4

8Are serum leptin levels predicted by lipoproteins, vitamin D and body composition?显示文摘BACKGROUND Both obesity and vitamin D deficiency are important health issues in Pakistan.The connection between body composition, Vitamin D and leptin in young adults is important to be studied as body composition may affect bone health and therefore the possibility of osteoporosis in later life. Few studies have attempted to investigate the effect of body composition and leptin with vitamin D in adolescence.AIM To investigate the association of serum leptin with body composition, lipids and25-hydroxyvitamin D(25 OHD) in adults.METHODS This cross-sectional study was conducted on 167 apparently healthy adults.Demographics were recorded, bioelectrical impedance analysis was performed and clinical history noted. Serum leptin was measured using DIA source kit on ELISA and total 25 OHD was measured on ADVIA-Centaur; Siemens. Total cholesterol and high density lipoprotein cholesterol were quantified using Enzymatic Endpoint Method and Cholesterol Oxidase-Phenol Aminophenazone method respectively. Biochemical analysis was done in the Departments of Pathology and Laboratory Medicine and Biological and Biomedical Sciences, Aga Khan University Hospital Karachi Pakistan.RESULTS Median age of the group(n = 167) was 20 years(IQR 27-20); 55.7% were females.Majority(89.2%, n = 149) of the study group was 25 OHD deficient, 6%(n = 10)had insufficient serum 25 OHD levels and 4.8%(n = 8) had sufficient D levels.Females, had higher median leptin levels [2.71(IQR 4.76-1.66 ng/mL)] compared to their counterparts [1.3(3.60-0.54 ng/mL), P < 0.01]. Multiple regression analysis suggested that basal metabolic rate, muscle mass, body fat percent, bone mass and serum 25 OHD were the most contributing factors to serum leptin levels. Bone mass and serum 25 OHD in fact bore a negative correlation with leptin.CONCLUSION The results indicate that basal metabolic rate, muscle mass, body fat percent, bone mass and serum 25 OHD have an impact on serum leptin. Being a cross sectional study causal relationship between leptin and other variables could not be determined.Aysha Habib Khan Syeda Sadia Fatima Ahmed Raheem Lena Jafri 2019World Journal of Diabetes2019,10,4:4
9Malnutrition and liver disease in a developing country显示文摘Malnutrition is a highly prevalent and under recognized condition in developing countries of South Asia.The presence of malnutrition causes a severe impact on patients with liver cirrhosis.The etiology of cirrhosis differs in the South Asian region compared to the West,with hepatitis B and C still being the leading causes and the prevalence of nonalcoholic fatty liver disease increasing over time.Comorbid malnutrition worsens outcomes for cirrhosis patients.Urgent attention to address malnutrition is needed to improve patient outcomes.The etiology and pathophysiology of malnutrition in liver diseases is multifactorial,as reduction in liver function affects both macronutrients and micronutrients.A need for nutritional status assessment for liver disease patients exists in all parts of the world.There are many widely studied tools in use to perform a thorough nutritional assessment,of which some tools are low cost and do not require extensive training.These tools can be studied and evaluated for use in the resource limited setting of a country like Pakistan.Treatment guidelines for proper nutrition maintenance in chronic liver disease exist for all parts of the world,but the knowledge and practice of nutritional counseling in Pakistan is poor,both amongst patients and physicians.Emphasis on assessment for nutritional status at the initial visit with recording of vital signs is needed.Simultaneously,treating physicians need to be made aware of the misconceptions surrounding nutritional restrictions in cirrhosis so that patient education is done correctly based on proper scientific evidence.Asra tus Saleha Siddiqui Om Parkash Syeda Amrah Hashmi 2021World Journal of Gastroenterology2021,27,30:3
10UV Assisted Preliminary DNA Binding Studies and Single-crystal X-ray Structure of 4-{(4-Nitrophenyl-sulfonamido)methyl}cyclohexanecarboxylic Acid显示文摘A new sulfonamide, 4-{(4-nitrophenylsulfonamido)methyl}cyclohexanecarboxylic acid(C14H18N2O6S), has been synthesized by the reaction of tranexamic acid and 4-nitrobenzenesulfonyl chloride in basic medium at room temperature. The molecular structure was determined by FT-IR, NMR, elemental analysis and single-crystal X-ray technique. X-ray diffraction shows that the compound crystallizes in the monoclinic system, space group P21/c with a = 13.5980(7), b = 4.9877(2), c = 23.3878(13) ?, β = 93.254(3)o, Z = 4, V = 1583.67(14) ?3, μ = 0.237 mm-1, F(000) = 720, R = 0.0471 and w R = 0.1182. The molecules are related by inversion and paired into dimers via C–H···O interactions. The dimmers are interlinked due to strong N–H···O bonds, where O-atoms are of sulfonyl groups. The molecules are stabilized in the form of infinite two-dimensional network with base vectors [0 1 0] and [0 0 –1] in the plane(1 0 2). The existence of good intermolecular interactions suggests the biological importance of the synthesized molecule. The compound was screened for its interaction with FS-DNA using UV-visible spectroscopy. UV-visible spectroscopic results depict that the compound interacts with DNA by mixed binding mode intercalation along with hydrogen bonding. Negative values of ΔG(–23.34, –17.79 k J·mol-1) indicate spontaneity of the compound-DNA adduct formation.MUHAMMAD Danish RABIA Ayub Butt MUHAMMAD Nawaz Tahir MUHAMMAD Ashfaq SYEDA Tahira Hafeez 2017Chinese Journal of Structural Chemistry2017,36,5:3
