Biosynthesis of Graphene and Investigation of Antibacterial Activity of Graphene-parthenium hysterophorous Nanocomposite

Abstract There is a great interest to use carbon-based material like graphene and graphene oxide in biomedical applications due to its flexibility to be functionalized with bio-active molecules. Herein, graphene and graphene-based nanocomposites were biosynthesized by liquid-phase exfoliation of graphite using aqueous extract of Parthenium hysterophorous (P-H) as a surfactant. A set of five thin film samples of graphene was prepared from graphene suspension by vacuum filtration method. Samples were characterized by UV-vis spectroscopy, Raman spectroscopy, SEM, and XRD, which revealed successful synthesis of graphene. Graphene/P-H(G/P-H) nanocomposites comprising varied ratios of graphene and P-H were prepared and their antibacterial activity was investigated by agar well diffusion method. The experimental results indicated that G/P-H nanocomposite have higher antibacterial activity than graphene alone, and bioactivity of G/P-H nanocomposite was found to be controlled by the fraction of graphene in the composite.

Outcome of radioactive iodine therapy in Toxic Nodular Goiter in Pakistan

Objective: To determine the outcome of patients receiving radioactive iodine therapy for toxic nodular goiter coming to Aga Khan University Hospital Karachi

Methods: A total of 89 patients who visited the outpatient department of Aga Khan University Hospital from January 2010 to August 2017 were recruited for the study. Toxic nodular goiter was diagnosed on the basis of having hot nodule on thyroid scan with low TSH and high FT4/T4. Other demographic and laboratory data were also recorded

Results: Eighty nine patients with toxic nodular goiter received a dose range from 10 to 30mCi RAI. Six months after RAI, 36.2 percent became hypothyroid, 38.5 percent became euthyroid while 25.3 percent remained hyperthyroid. Thyroid outcome at 3 months were correlating with 6 months results

Conclusion: Radioactive iodine therapy is a safe and effective way of treating toxic nodular goiter which usually results in cure of hyperthyroidism in majority of patients

Evaluation of maxillary central incisor width by regression analysis in different face forms

Restoration of esthetics and function are the primary objectives of prosthodontic rehabilitation. Estimating the width of central maxillary incisor mesiodistally is a tedious task in edentulous subject having no pre-extraction records. Several anthropometric measurements of face have been advocated as a guide to calculate the width of central maxillary incisors in edentulous subjects. The study was conducted in Faryal Dental College to assess relationship between the inner canthal distance with maxillary central incisor width in squarish, ovoid and tapering face forms by regression analysis and whether it is applicable in selection of maxillary anterior teeth in edentulous patients. The face forms of different patients were evaluated by subjecting the photographs to computer analysis. Regression analysis was performed to find the relationship of maxillary central incisor width to inner canthal distance both of which were measured by vernier calipers in patients having no facial or dental deformaties. The statistically significant result of this study proved that there is weak association between inner canthal distance and mesiodistal width of central incisors. The inner canthal distance cannot be taken as dependable anthropometric measurement to select central maxillary incisor width

Evaluation of DNA vaccines encoding M. Tb gene Bfrb and Mpt32 in mice model

Tuberculosis [TB] is a life threatening infectious disease which is prevalent throughout the world. Mycobacterium bovis based Bacille Calmette-Gue'rin [BCG] is the only vaccine available against TB however, this [single] vaccine is not enough to eradicate it. Furthermore, numbers of researches from different parts of the World have shown its efficacy as variable. Hence other [better] vaccines like DNA vaccines are needed in addition to BCG in order to achieve desired goal of TB eradication. The current study was aimed to develop subunit based DNA vaccines against TB and to check their efficacy. Two constructs Bfrb-pND14 and Mpt32-pND14 were made and used as DNA vaccines. Endotoxin free DNA preparations were made and used in immunization studies. Twenty Balb/c female mice of age eight weeks were used in trial. Two experimental groups each comprising eight animals were used to inoculate Mpt32-pND14 and Bfrb-pND14 vaccines respectively. A group of four animals was used as negative control. Animals were bled through tail periodically and finally through cardiac puncture before euthanization. Antibodies were confirmed through dot blot and Agar Gel Immuno Diffusion test [AGID]. All the animals immunized with both vaccines were found positive as tested through dot blot and AGID. The results of this study have indicated that both the M. tb genes have produced strong immune response in mice model through pND14 vector and proved themselves as good subunit based DNA vaccines

Stability indicating RP-HPLC method for simultaneous determination of piroxicam and ofloxacin in binary combination

A simple and precise RP-HPLC method was developed for simultaneous determination of piroxicam and ofloxacin in pharmaceutical formulations and human serum. Optimum separations of piroxicam, ofloxacin and stress-induced degradation products were achieved by use of Hypersil BDS C8 column [250 x 4.6mm, 5microm]. The mobile phase was a mixture of acetonitrile: 0.012M K[2]HPO[4]: 0.008M sodium citrate [both buffers mixed and pH adjusted to 2.8] [50:25:25 v/v/v] delivered at flow rate of 1.5mL min[-1] using DAD at 254nm. Response was linear function of concentration over the ranges of 70-130mg mL[-1] for piroxicam and ofloxacin [r[2]>/=0.999]. The method efficiently separated the analytical peaks from degradation products with acceptable tailing and resolution. The developed method was successfully used for concurrent analysis of piroxicam and ofloxacin in pharmaceutical formulations, human serum and in vitro drug interaction studies

Validity of pleural fluid protein in differentiating tuberculouse from malignant pleural effusion keeping histopathology as gold standard. Cross sectional study. This study was conducted in the Pulmonology department post graduate medical institute, Lady Reading Hospital Peshawar, Khyber Pakhtunkhwa [KPK] Pakistan from March 2009 to March 2010. One hundred and seventy nine patients having clinical suspicion of pulmonary tuberculouse and malignancy and fulfilling the inclusion criteria were subjected to Abrams needle biopsy, plural tissue was examined by histopathology. Biopsy in order to know the significant difference of pleural fluid protein level between tuberculous and malignant pleural effusion, histopathology finding and protein concentration were determined their frequency and percentage. Among total number of 179 patients one hundred and fourteen [63.69%] were male and sixty five [36.32%] were female. The age limit from 15-80 years, the result shows that 60.9% were tuberculous and 39.9% were malignant pleuraleffusion, among these malignant 20 [11.2%] showed primary and 50 [27.9%] secondary malignancy. Tuberculous PE was more common in younger age group while malignant PE in older age group, 32 number of patients falling in category A, 59 in category B, and 88 in category C.A protein level in belonging to category C, there was statistically significant difference between tuberculous and malignant PE, tuberculous PE have high concentration of protein than malignant PE, The category [A] have malignant PE. Plural fluid total protein level determination and differentiating is a valuable tool in reaching to the diagnosis of suspectedtuberculouse from malignant pleural effusion provided it is used in addition to the adequate clinical scenario

High sero-prevalence of transfusion transmitted infections among prisoner blood donors from Punjab prisons

Objective: prisoners as a high risk group are never recommended for blood donations. In Pakistan, prisoners are legally allowed to donate blood and get thirty days extra remission. In Pakistan, there is not much published data on prisoner blood donors. The study aimed to estimate the sero-prevalence of human immunodeficiency virus [HIV], Hepatitis B with [HBV], Hepatitis C virus [HCV] and Syphilis among physically healthy prisoner blood donors in prisons of Punjab

Material and Methods: a retrospective review of record of all prisoner donors who donated blood during camps from January 2007 to December, 2009 was carried out in January 2010. Physically fit prisoner donors were tested for HCV, HBV, HIV and Syphilis by rapid test kits before donation. Those found negative for these infections were allowed to donate blood. Donated blood was retested for anti-HIV, anti-HCV and HBsAg by ELISA and syphilis by VDRL

Results: a total of 3,074 prisoner donors were tested. 3050 [99%] donors were male. Mean age was 28 years [17-57 yr.]. Among prisoners, 235 [7.6%] were positive for HCV, 114 [3.7%] for Syphilis, 111 [3.6%] for HBV and 21 [0.7%] for HIV. Among these, 434 [14%] were positive for at least one of these infections. Three females [12.5%] were positive for syphilis and one [4.14%] for hepatitis B

Conclusion: the prevalence of HIV, HBV, HCV and syphilis is higher in prison donors as compared to blood donors from general population. So prison inmates constitute a very high risk group among blood donors. Stringent screening of blood donors and even testing of donated blood by highly sensitive tests is recommended. We also recommend further studies and then modify blood donation laws accordingly

Frequency of hypodontia in a tertiary care hospital of Karachi

To compare frequency of missing teeth in samples of population from Karachi. Cross-sectional study. This study was conducted in Department of Orthodontics, Karachi Medical and Dental College from October 2011 to October 2012. During the study period, 465 panoramic radiographs were evaluated and according to exclusion and inclusion criteria 309 panoramic radiographs were selected, out of which 109 [35.27%] were males and 200 [64.73%] were females. The patients were 12-25 years old. Data were collected and entered into the SPSS software [version 18; Chicago] to calculate frequencies, percentages and mean +/- SD. 02 males were found with hypodontia [1.83%] while 10 females were found with hypodontia [5%]. Few teeth like maxillary central incisors, 1[st] premolar and 1[st] molar in both arches show no congenital absence. A total of 17 teeth, [males = 3, females = 14] in 12 patients were congenitally missing. The most common congenitally missing teeth were maxillary left 2 incisor 23.52% followed by mandible left 2 pre-molar 17.64%. By early detection of missing teeth, alternative treatment modalities can be planned and minimize the complications of CMT. In this study it has been observed that among the population of Karachi threshold for agenesis of maxillary left 2nd incisors is the most commonly missing, followed by mandibular 2[nd] premolars

Mucocutaneous manifestations in hepatitis C patients

To determine the frequency and nature of mucocutaneous manifestations in hepatitis C virus [HCV] positive patients. Two hundred and five HCV positive patients presenting at the outpatient and inpatient departments of Services Hospital, Lahore were evaluated for mucocutaneous manifestations. Relevant data regarding history, clinical examination including cutaneous system and investigations were documented and analyzed. Mean age of patients was 36.6 +/- 11.0 years. There were 84 [41%] males and 121 [59%] females. 73.7% cases were exposed to antiviral therapy. Dermatological manifestations were present in 88.3% patients with HCV infection. Pruritus was the most common finding seen in 39.5% followed by hyperpigmentation of skin 34.1%, lichen planus 18%, lingual/buccal pigmentation 13.2%, melanonychia 12.7% and urticaria 6.8%. Less frequent features were palmar erythema, photosensitivity and cutaneous vasculitis. Dermatological manifestations may appear as an earliest sign of hepatitis C infection. Therefore, vigilant detection and careful investigation can prevent the complications and further spread of this dreadful disease

Should we routinely expose recurrent laryngeal nerve[s] during thyroid surgery?

To compare the frequency of recurrent laryngeal nerve[s] [RLNs] palsy after various thyroid procedures with and without identification of recurrent laryngeal nerve during the operation. Randomized controlled trial. Department of Surgery, Military Hospital, Rawalpindi, from August 2008 to April 2010. Patients undergoing indirect laryngoscopy with normal vocal cords and those with carcinoma and re-do surgery having normal vocal cord were included in the study. Patients with hoarseness of voice, abnormal vocal cord movements and with solitary nodule in the isthmus were excluded. These patients were randomly divided into 2 groups of 50 each using random number tables. RLN was identified by exposing the inferior thyroid artery and traced along its entire course in group-A. Whereas, in group-B, nerves were not identified during the operations. Immediate postoperative direct laryngoscopy was performed by a surgeon with the help of an anaesthesiologist for the assessment of vocal cords. Patients with persistent hoarseness of voice were followed-up with indirect laryngoscopy at 3 and 6 months. Temporary unilateral recurrent laryngeal nerve palsies occurred in 2 [4%] patients in group-A where the voice and cord movements returned to normal in 6 months. In group-B, it occurred in 8 [16%] patients, 2 bilateral [4%] injuries requiring tracheostomy and 6 unilateral injuries [12%]. Among the 2 bilateral recurrent laryngeal nerve injuries, the tracheostomy was removed in one case after 6 months with persistent hoarseness of voice but no respiratory difficulty during routine activities. Tracheostomy was permanent in the other case. Among the 6 cases of unilateral nerve injuries, the voice improved considerably in 4 cases within 6 months but in 2 cases hoarseness persisted even after 6 months. Frequency of recurrent laryngeal nerve palsies was significantly lower in group-A as compared to group-B [p = 0.046]. For safe thyroid surgery, recurrent laryngeal nerve[s] should be routinely exposed in its entire course

First cancer statistics report from Hazara division

'Cancer' is on rise globally. Cancer registry is vital for policy making, resource allocation, progress tracking and overall cancer control. In Pakistan, cancer prevention, screening and standardised clinical trials, as well as quality assurance through surveillance are badly hampered due to the lack of a National Cancer Registry. For Pakistan a well-integrated system of Cancer Registry is need of the day. This retrospective study was conducted on the hospital records at the Oncology Department of Ayub Teaching Hospital, Abbottabad from year 2007-12. Data were collected through a standard data capture form with a final figure of 555 patients. The malignancies were diagnosed clinically and histopathologically at different laboratories of Pakistan. Among these cases, 54.08% were male and 45.92% female. Incidence of cancer in patients below 14 years age was 8.47% and 91.53% above 14 years. Majority [31.95%] cases were from Mansehra followed by Abbottabad with 27.08% and Haripur 14.26% cases. Leukaemias were at top with 15.14% cases followed by breast carcinoma [13.69%], Lymphomas [12.07%], ovarian carcinomas [8.65%], and gastric carcinoma and skin cancers with 2.70% each. Among men, the highest incidence was of Hodgkin's lymphoma [14.9%] followed by lymphocytic leukaemia [14.3%]. Prostate cancer was seen in 8.3% male patients. Another 5.7% patients had lung cancer. In women, the highest incidence was carcinoma breast [19.7%] followed by ovarian carcinoma [13.4%], leukaemia [9.7%], and Hodgkin's lymphoma [4.3%]. A variety of cancers are prevalent in the indigent population. Record-keeping in wards is sub-optimal. Commonest cancers in the area have slight differences with rest of the country

Oral cavity tumours, a clinical experience in a tertiary care center

To determine the age range, gender distribution, histological types, sites, neck node involvement, and surgery as modality of treatment in diagnosed cases of oral cavity tumours in a tertiary care centre. Descriptive Study. The study was carried out in ENT Department, CMH Rawalpindi for the duration from Dec 2008- Dec 2011. Data of 113 biopsy proven cases of oral cavity tumors who underwent surgery at CMH Rawalpindi, were retrieved from Armed Forces Institute of Pathology's Tumour Registry and from Head and Neck Oncology Forum Registry, and were evaluated. Out of 113 patients with oral cavity tumours, 87 [77%] were male, while 26 [23%] were female, the male: female ratio being 3:1. The mean age of the patients was 59.4 years, ranging from 40 to 75 years. Site distribution of the tumours was: Tongue: 61[54%], buccal mucosa 24 [21%], floor of mouth 18 [16%], and hard palate 10 [9%]. The histology of tumours showed Squamous cell carcinoma in 102 [90%] and tumours of Salivary gland origin in 11 [10%]. Sixty four [56%] of these patients had N0 disease, 10 [9%] had N1 disease, 8 [7%] had N[2s] disease, 27 [25%] had N[2b] disease, 3 [2%] had N[2c] disease, while 1 patient [1%] had N[3] disease. Resection of the tumour along with Supra-omohyoid neck dissection was carried out in 64 [56%] patients, while resection with radical neck dissection was done in 49 [44%] patients. Primary closure was carried out in 62 [55%] patients, while secondary reconstruction was done in 51 [45%] patients. Presentation of oral cavity tumours occur at an advanced age with male preponderance in our population. Early presentation results in lesser local spread, leading to less aggressive surgical approach with selective neck dissection

Effects of ciprofloxacin and zinc chloride in adult albino rat and pre-natal conceptus

Administration of quinolone therapy is controversial during growing age as stated by earlier authors. The flouroquinolones are currently not indicated for young children because of arthropathy and adverse effect as new born shown by studies. However the effects of ciprofloxacin and ZnCl[2] on prenatal conceptus have remained undocumented. The present study was designed to compare the effects on conceptus after maternal ingestion of ciprofloxacin and ZnCl[2] using Wastar albino rats. Ciprofloxacin and ZnCl[2] was administrated to pregnant female albino rats. Ciprofloxacin with a dose of 20 mg/Kg bodyweight and ZnCl[2] 120 microg/100 gm bodyweight two times therapeutic dose for 10 days [from day 8-18 of pregnancy]. Each animal was weighted on day 1, day 8 and day 18 of pregnancy. Abortion resulted on day 18[th] of pregnancy. Each group of pregnant animals were sacrificed on day 18 of gestation by over dose of either anaesthesia, abdomen opened, uterus and both cornua containing conceptus identified, removed, there weight recorded, crown rump length was measured and was compared with similar value of control animals. The results were statistically analysed to find out the significance. The ciprofloxacin induces a mordanting effect as obviated by increased basophilia. Our study reveals that ciprofloxacin administered in maternal, decreased maternal body weight to 38.4 +/- 0.9 gm. However simultaneous ZnCl[2] maintained the body weight to 41.4 +/- 0.7 gm, while ZnCl[2] increased the body weight to 46.5 +/- 2.25 gm. The body weight and Crown Rump length [CR Length] in conceptus decreased by 4.52 +/- 0.10 gm and 3.06 +/- 0.09 Cm respectively. That ciprofloxacin and ZnCl[2] administration maintained the body weight and CR length by 5.46 +/- 0.09 gm and 3.79 +/- 0.13 Cm respectively. That ZnCl[2] administration increased the body weight and CR length by 6.71 +/- 0.05 gm and 4.15 +/- 0.08 Cm respectively. Prenatal administration of Ciprofloxacin caused reduction in growth rate and CR length, and ZnCl[2] maintained body weight and CR length and growth of the rat conceptus.
