| 1 | Choice of wound care in diabetic foot ulcer: A practical approach显示文摘Diabetic foot ulcers are the consequence of multiple factors including peripheral neuropathy,decreased blood supply,high plantar pressures,etc.,and pose a significant risk for morbidity,limb loss and mortality.The critical aspects of the wound healing mechanism and host physiological status in patients with diabetes necessitate the selection of an appropriate treatment strategy based on the complexity and type of wound.In addition to systemic antibiotics and surgical intervention,wound care is considered to be an important component of diabetic foot ulcer management.This article will focus on the use of different wound care materials in diabetic foot.From a clinical perspective,it is important to decide on the wound care material depending on the type and grade of the ulcer.This article will also provide clinicians with a simple approach to the choice of wound care materials in diabetic foot ulcer. | Karakkattu Vijayan Kavitha Shalbha Tiwari Vedavati Bharat Purandare Sudam Khedkar Shilpa Sameer Bhosale Ambika Gopalakrishnan Unnikrishnan | 2014 | World Journal of Diabetes2014，5，4： | 20 |
| 2 | Micro RNAs potential utility in colon cancer: Early detection, prognosis, and chemosensitivity显示文摘Over the past decade, research has shown that aberrant expression of micro RNA(mi RNA) is involved in colorectal cancer development and progression. Micro RNAs are small sequences of non-coding RNA that regulate expression of genes involved in important cellular functions, such as cell differentiation, multiplication, and apoptosis. A specific mi RNA may display the effects of a tumor suppressor or oncogene. Altered mi RNA expression is found in colorectal cancer(CRC) and patterns of mi RNA expression correlate with CRC detection and outcome. Studies also have examined the use of circulating serum mi RNA and fecal mi RNA expression as non-invasive markers for early detection. Here, we review recent evidence demonstrating the potential role of mi RNA in CRC and the implications of its use in the diagnosis, prognosis, and management of CRC. | Michael Hollis Kavitha Nair Arpita Vyas Lakshmi Shankar Chaturvedi Sahil Gambhir Dinesh Vyas | 2015 | World Journal of Gastroenterology2015，21，27： | 19 |
| 3 | Role of dental plaque,saliva and periodontal disease in Helicobacter pylori infection显示文摘Helicobacter pylori(H.pylori)infection is one of the most common bacterial infections in humans.Although H.pylori may be detected in the stomach of approximately half of the world’s population,the mechanisms of transmission of the microorganism from individual to individual are not yet clear.Transmission of H.pylori could occur through iatrogenic,fecal-oral,and oral-oral routes,and through food and water.The microorganism may be transmitted orally and has been detected in dental plaque and saliva.However,the role of the oral cavity in the transmission and recurrence of H.pylori infection has been the subject of debate.A large number of studies investigating the role of oral hygiene and periodontal disease in H.pylori infection have varied significantly in terms of their methodology and sample population,resulting in a wide variation in the reported results.Nevertheless,recent studies have not only shown that the microorganism can be detected fairly consistently from the oral cavity but also demonstrated that the chances of recurrence of H.pylori infection is more likely among patients who harbor the organism in the oral cavity.Furthermore,initial results from clinical trials have shown that H.pylori-positive dyspeptic patients may benefit from periodontal therapy.This paper attempts to review the current body of evidence regarding the role of dental plaque,saliva,and periodontal disease in H.pylori infection. | Pradeep S Anand Kavitha P Kamath Sukumaran Anil | 2014 | World Journal of Gastroenterology2014，20，19： | 15 |
| 4 | Stereotactic body radiation therapy for non-small cell lung cancer:A review显示文摘Stereotactic body radiation therapy(SBRT) is the treatment of choice for medically inoperable patients with early stage non-small cell lung cancer(NSCLC). A literature search primarily based on PubMed electronic databases was completed in July 2018. Inclusion and exclusion criteria were determined prior to the search, and only prospective clinical trials were included. Nineteen trials from 2005 to 2018 met the inclusion criteria, reporting the outcomes of 1434 patients with central and peripheral early stage NSCLC. Patient eligibility,prescription dose and delivery, and follow up duration varied widely. Threeyears overall survival ranged from 43% to 95% with loco-regional control of up to 98% at 3 years. Up to 33% of patients failed distantly after SBRT at 3 years. SBRT was generally well tolerated with 10%-30% grade 3-4 toxicities and a few treatment-related deaths. No differences in outcomes were observed between conventionally fractionated radiation therapy and SBRT, central and peripheral lung tumors, or inoperable and operable patients. SBRT remains a reasonable treatment option for medically inoperable and select operable patients with early stage NSCLC. SBRT has shown excellent local and regional control with toxicity rates equivalent to surgery. Decreasing fractionation schedules have been consistently shown to be both safe and effective. Distant failure is common, and chemotherapy may be considered for select patients. However, the survival benefit of additional interventions, such as chemotherapy, for early stage NSCLC treated with SBRT remains unclear. | Kavitha M Prezzano Sung Jun Ma Gregory M Hermann Charlotte I Rivers Jorge A Gomez-Suescun Anurag K Singh | 2019 | World Journal of Clinical Oncology2019，10，1： | 10 |
| 5 | Stair and Step Soliton Solutions of the Integrable (2+1) and (3+1)-Dimensional Boiti-Leon-Manna-Pempinelli Equations显示文摘The multiple exp-function method is a new approach to obtain multiple wave solutions of nonlinear partial differential equations (NLPDEs). By this method one can obtain multi-soliton solutions of NLPDEs. In this paper, using computer algebra systems, we apply the multiple exp-function method to construct the exact multiple wave solutions of a (2+1)-dimensional Boiti-Leon-Manna-Pempinelli equation. Also, we extend the equation to a (3+1)-dimensional case and obtain some exact solutions for the new equation by applying the multiple exp-function method. By these applications, we obtain single-wave, double-wave and multi-wave solutions for these equations. | M.T. Darvishi M. Najafi L. Kavitha M.

| 6 | Determination of the mechanism of photoinduced toxicity of selected metal oxide nanoparticles(ZnO,CuO,Co_3O_4 and TiO_2)to E.coli bacteria显示文摘Cytotoxicity of selected metal oxide nanoparticles(MNPs)(ZnO,CuO,Co 3 O 4 and TiO 2)was investigated in Escherichia coli both under light and dark conditions.Cytotoxicity experiments were conducted with spread plate counting and the LC 50 values were calculated.We determined the mechanism of toxicity via measurements of oxidative stress,reduced glutathione,lipid peroxidation,and metal ions.The overall ranking of the LC 50 values was in the order of ZnO < CuO < Co 3 O 4 < TiO 2 under dark condition and ZnO < CuO < TiO 2 < Co 3 O 4 under light condition.ZnO MNPs were the most toxic among the tested nanoparticles.Our results indicate depletion of reduced glutathione level and elevation of malondialdehyde level correlated with the increase in oxidative stress.Released metal ions were found to have partial effect on the toxicity of MNPs to E.coli.In summary,the dynamic interactions of multiple mechanisms lead to the toxicity of the tested MNPs to E.coli. | Thabitha P.Dasari Kavitha Pathakoti Huey-Min Hwang | 2013 | Journal of Environmental Sciences2013，25，5： | 9 |
| 7 | Antibacterial activity of leaves and inter-nodal callus extracts of Mentha arvensis L显示文摘Objective:To determine the anti-bacterial efficacy of chloroform,ethanol,ethyl acetate and water extracts of inter-nodal and leaves derived calli extracts from Mentha arvensis(M.arvensis) against Salmonella typhi(S.typhi),Streptococcus pyogenes(S.pyogenes),Proteus vulgaris(P. vulgaris) and Bacillus subtilis(B.subtilis).Methods:The inter-nodal and leaves segments of M.arvensis were cut into 0.5-0.7 cm in length and cultured on Murashige and Skoog solid medium supplemented with 3%sucrose,gelled with 0.7%agar and different concentration of 2,4-Dichlorophenoxyacetie acid(2,4-D) either alone or in combinations.The preliminary phytochemical screening was performed by Brindha et al method.Antibacterial efficacy was performed by disc diffusion method and incubated for 24 h at 37℃.Results:Maximum percentage of callus formation(inter-nodal segments 84.3±0.78;leaves segments 93.8±1.27) was obtained on Murashige and Skoog’s basal medium supplemented with 3%sucrose and 1.5 mg/L of 2,4-D.The ethanol extracts of leaves derived calli showed the maximum bio-efficacy than other solvents.The leaves and stem derived calli extracts on Proteus sp.showed that the plants can be used in the treatment of urinary tract infection associated with Proteus sp.Through the bacterial efficacy studies,it is confirmed that the in vitro raised calli tissue was more effective compared to in vivo tissue.Conclusions:The bio-efficacy study confirmed that the calli mediated tissues showed the maximum zone of inhibition.The present study paved a protocol to establish high potential cell lines by in vitro culture. | Johnson M Wesely EG Kavitha MS Uma V | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，3： | 9 |
| 8 | Hypoxia-inducible factor 2α is a negative regulator of osteoblastogenesis and bone mass accrual显示文摘Osteoblasts,which are the bone-forming cells,operate in a hypoxic environment.The transcription factors hypoxia-inducible factor-1α(HIF1)and HIF2 are key mediators of the cellular response to hypoxia.Both are expressed in osteoblasts.HIF1 is known to be a positive regulator of bone formation.Conversely,the role of HIF2 in the control osteoblast biology is still poorly understood.In this study,we used mouse genetics to demonstrate that HIF2 is an inhibitor of osteoblastogenesis and bone mass accrual.Moreover,we provided evidence that HIF2 impairs osteoblast differentiation at least in part,by upregulating the transcription factor Sox9.Our findings constitute a paradigm shift,as activation of the hypoxia-signaling pathway has traditionally been associated with increased bone formation through HIF1.Inhibiting HIF2 could thus represent a therapeutic approach for the treatment of the low bone mass observed in chronic diseases,osteoporosis,or aging. | Christophe Merceron Kavitha Ranganathan Elizabeth Wang Zachary Tata Shreya Makkapati Mohd Parvez Khan Laura Mangiavini Angela Qing Yao Laura Castellini Benjamin Levi Amato J.Giaccia Ernestina Schipani | 2019 | Bone Research2019，7，1： | 7 |

| 10 | BK nephropathy in the native kidneys of patients with organ transplants: Clinical spectrum of BK infection显示文摘Nephropathy secondary to BK virus, a member of the Papoviridae family of viruses, has been recognized for some time as an important cause of allograft dysfunction in renal transplant recipients. In recent times, BK nephropathy(BKN) of the native kidneys has being increasingly recognized as a cause of chronic kidney disease in patients with solid organ transplants, bone marrow transplants and in patients with other clinical entities associated with immunosuppression. In such patients renal dysfunction is often attributed to other factors including nephrotoxicity of medications used to prevent rejection of the transplanted organs. Renal biopsy is required for the diagnosis of BKN. Quantitation of the BK viral load in blood and urine are surrogate diagnostic methods. The treatment of BKN is based on reduction of the immunosuppressive medications. Several compounds have shown antiviral activity, but have not consistently shown to have beneficial effects in BKN. In addition to BKN, BK viral infection can cause severe urinary bladder cystitis, ureteritis and urinary tract obstruction as well as manifestations in other organ systems including the central nervous system, the respiratory system, the gastrointestinal system and the hematopoietic system. BK viral infection has also been implicated in tumorigenesis. The spectrum of clinical manifestations from BK infection and infection from other members of the Papoviridae family is widening. Prevention and treatment of BK infection and infections from other Papovaviruses are subjects of intense research. | Darlene Vigil Nikifor K Konstantinov Marc Barry Antonia M Harford Karen S Servilla Young Ho Kim Yijuan Sun Kavitha Ganta Antonios H Tzamaloukas | 2016 | World Journal of Transplantation2016，6，3： | 4 |

| 12 | Prolonged hypernatremia triggered by hyperglycemic hyperosmolar state with coma: A case report显示文摘A man with past lithium use for more than 15 years, but off lithium for two years and not carrying the diagnosis of diabetes mellitus or nephrogenic diabetes insipidus(NDI), presented with coma and hyperglycemic hyperosmolar state(HHS). Following correction of HHS, he developed persistent hypernatremia accompanied by large volumes of urine with low osmolality and no response to desmopressin injections. Urine osmolality remained < 300 m Osm/kg after injection of vasopressin. Improvement in serum sodium concentration followed the intake of large volumes of water plus administration of amiloride and hydrochlorothiazide. Severe hyperglycemia may trigger symptomatic lithium-induced NDI years after cessation of lithium therapy. Patients with newonset diabetes mellitus who had been on prolonged lithium therapy in the past require monitoring of their serum sodium concentration after hyperglycemic episodes regardless of whether they do or do not carry the diagnosis of NDI. | Darlene Vigil Kavitha Ganta Yijuan Sun RichardⅠDorin Antonios H Tzamaloukas Karen S Servilla | 2015 | World Journal of Nephrology2015，4，2： | 3 |

| 14 | Clinical profile of brucellosis from a tertiary care center in southern India显示文摘Objective:To highlight the spectrum of clinical manifestations,labs,complications,treatment and outcome of brucellosis.Methods:Retrospective study was conducted in Kasturba Medical College,Manipal University,Karnataka,India which included 68 confirmed cases of brucellosis from January 2006- April 2010.Diagnosis of brucellosis was made by culturing the sera/body fluids by standard BACTEC method(or) by testing the sera for Brucella agglutinins using the standard agglutination test(SAT).A titer of 1:320 or more was considered as significant.SPSS 16 was used for statistical analysis and Microsoft Excel for graphical representation.Results:Of the 68 patients,46(68%) were male and 22(32%) were female patients with age distribution of 9-75 years.Forty four(64.7%) had history of contact with unpasteurized dairy products or infected animals.Symptoms included fever(68,100%),myalgia(21,31%),musculoskeletal symptoms (23,34%),headache(16,24%),gastrointestinal symptoms(19,28%) and altered sensorium(3, 4%).Co-morbidities and associations included HIV positivity(2,3%),type 2 diabetes mellitus (13,19%),steroid therapy(3,4%) and HBsAg positivity(8,12%).Ten(15%) patients had cervical lymphadenopathy,4(6%) had splenic enlargement,6(7%) had hepatomegaly,19(28%) had hepatosplenomegaly and 2(3%) got meningeal signs.Anaemia was observed in 39(57.3%) cases,high erythrocyte sedimentation rate(ESR) was present in 55(80.8%) cases,leucocytosis in 10(14.7%),leucopenia in 10(14.7%),thrombocytopenia in 23(33.82%) and thrombocytosis in 2(2.94%) cases.Conclusions:In countries like India,where brucellosis and tuberculosis are endemic;rapid,sensitive and highly specific diagnostic methods are required to make early diagnosis and prevent resistance as there is an overlap in therapy. | Vishwanath Sathyanarayanan Abdul Razak Kavitha Saravu Shastry Barkur Ananthakrishna Mukhyprana Prabhu M Vandana KE | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，5： | 3 |
| 15 | 纤维蛋白胶与无缝无胶自体球结膜瓣固定术治疗翼状胬肉的疗效比较(英文)显示文摘目的:比较两种大小纤维蛋白胶与无缝无胶自体球结膜瓣固定术在原发性翼状胬肉手术中的患者舒适度、移植物稳定性、移植物炎症、复发等术后并发症。方法:本研究对2014-12/2016-08共80例翼状胬肉患者(80眼)进行前瞻性介入对比研究。研究组随机抽取并分为两组,组1接受纤维蛋白胶疗法,组2采用无缝合无胶结膜自体移植固定术。每组再将等量的受试者随机平均分为两组(组1:组A+组B,组2:组C+组D)。组A(自体移植物的大小与裸眼巩膜相同)和组B(比裸巩膜大1 mm)实施纤维蛋白胶疗法;组C(自体移植物的大小与裸眼巩膜相同)和组D(比裸巩膜大1 mm)采用无缝线无胶结膜自体移植固定术。每一位患者都接受翼状胬肉切除术,并根据组别使用不同大小的自体球结膜瓣。结果:组1平均年龄为43.525,组2平均年龄为42.2。男性20例,女性60例。37例患者右眼有翼状胬肉。四组间平均手术时长相似。在术后随访期间,除结膜下出血(纤维蛋白胶组在术后1wk内明显增多)外,4组间患者的舒适度、移植物回缩、移植物炎症和移植物水肿等术后参数均相似(P<0.0001)。组2仅3例患者出现4级移植物回缩/移位。术后1wk,组A和组D各出现1例移植囊肿患者。随访6mo后,组D中2例患者复发。结论:两种方法均安全有效,术后不适及并发症少。与纤维蛋白胶疗法相比,无缝无胶疗法更加经济且效果相当。由于该手术成本低,且具有纤维蛋白胶疗法的所有优点,无缝无胶法可被认为是治疗患者非常有效的方法。 | Manipur Raviraj Sahana Chikkanayakanahalli Venugopal Kavitha Acharya Pavana Bomalapura Ramamurthy Lakshmi | 2019 | 国际眼科杂志2019，19，11： | 2 |
| 16 | In vitro cytotoxicity of CdSe/ZnS quantum dots with different surface coatings to human keratinocytes HaCaT cells显示文摘Quantum dots (QD) nanoparticles have been widely used in biomedical and electronics fields, because of their novel optical properties. Consequently it confers enormous potential for human exposure and environmental release. To increase the biocompatibility of QDs, a variety of surface coatings or functional groups are added to increase their bioactivity and water solubility. Human adult low calcium high temperature (HaCaT) cells are the epithelial cells derived from adult human skin that exhibits normal differentiation capacity and a DNA fingerprint pattern that is unaffected by long-term cultivation, transformation, or the presence of multiple chromosomal alternations. Human keratinocytes, HaCaT cells were used to systematically evaluate the cytotoxicity of biocompatible QD made of CdSe metal core and ZnS shell with three different coatings and at three different wavelengths (530, 580 and 620 nm). In terms of half- maximal inhibitory concentration, QSA-QDs with amine-polyethyleneglycol coating and QSH-QDs with amphiphilic polymer coating were not cytotoxic, while QEI-QDs with polyethylenimine coating were highly toxic to the HaCaT cells in comparison to a reference CuInS2/ZnS. QEI-QDs led to significant increase in reactive oxygen species, decrease in mitochondrial membrane potential and DNA damage in HaCaT cells. The mechanisms of toxicity of QEI-530 and QEI-580 can be attributed to the combination of intracellular reactive oxygen species production and loss of MMP. The QDs toxicity can be attributed to the polyethylemimine surface coating which was highly toxic to cells in comparison with amine-polyethyleneglycol, but not due to the release of cadmium ions. | Kavitha Pathakoti Huey-Min Hwang Hong Xu Zoraida P.Aguilar Andrew Wang | 2013 | Journal of Environmental Sciences2013，25，1： | 2 |
