Expression analysis of transcription factors in sugarcane during cold stress / Análise de expressão de fatores de transcrição em cana-de-açúcar sob estresse por frio

Transcription factors (TF) are a wide class of genes in plants, and these can regulate the expression of other genes in response to various environmental stresses (biotic and abiotic). In the current study, transcription factor activity in sugarcane was examined during cold stress. Initially, RNA transcript reads of two sugarcane cultivars (ROC22 and GT08-1108) under cold stress were downloaded from SRA NCBI database. The reads were aligned into a reference genome and the differential expression analyses were performed with the R/Bioconductor edgeR package. Based on our analyses in the ROC22 cultivar, 963 TF genes were significantly upregulated under cold stress among a total of 5649 upregulated genes, while 293 TF genes were downregulated among a total of 3,289 downregulated genes. In the GT08-1108 cultivar, 974 TF genes were identified among 5,649 upregulated genes and 283 TF genes were found among 3,289 downregulated genes. Most transcription factors were annotated with GO categories related to protein binding, transcription factor binding, DNA-sequence-specific binding, transcription factor complex, transcription factor activity in RNA polymerase II, the activity of nucleic acid binding transcription factor, transcription corepressor activity, sequence-specific regulatory region, the activity of transcription factor of RNA polymerase II, transcription factor cofactor activity, transcription factor activity from plastid promoter, transcription factor activity from RNA polymerase I promoter, polymerase II and RNA polymerase III. The findings of above results will help to identify differentially expressed transcription factors during cold stress. It also provides a comprehensive analysis of the regulation of the transcription activity of many genes. Therefore, this study provides the molecular basis for improving cold tolerance in sugarcane and other economically important grasses.

Partial purification, characterization and application of thermoalkaliphilic proteases from Priestia endophytica, Lysinibacillus cresolivorans and Bacillus subtilis isolated from desert soil

Aims@#Thermophilic proteases are important industrial enzymes because they can be used at high temperatures in various bioprocessing schemes. The bacterial population of the Cholistan desert was explored for thermophilic proteases and their industrial applications.@*Methodology and results@#Three bacterial isolates K1, K5 and K7 were found promising protease producers. These isolates were preliminary identified as Bacillus based on morphological characteristics and biochemical tests (positive for catalase, oxidase and citrate tests, and negative for indole and urease tests). The isolates K1, K5 and K7 were further identified as Priestia endophytica, Lysinibacillus cresolivorans and Bacillus subtilis, respectively by phylogenetic analysis. The isolates grew best at 50 °C and P. endophytica (K1), L. cresolivorans (K5) and B. subtilis (K7) produced larger zones of hydrolysis at 37 °C, 45 °C and 50 °C at pH 7, respectively. The optimum temperature where protease activity was maximum was 65 °C for P. endophytica and L. cresolivorans and 55 °C for B. subtilis, and the optimum pH was 9.@*Conclusion, significance and impact of study@#The proteases produced by these isolates were found active at high temperatures (45 °C to 85 °C) and high pH (9-12), which make them industrially important thermoalkaliphilic proteases. These proteases successfully de-haired cow’s skin and de-stained blood from cotton cloth pieces, which are rarely tested applications of these proteases.

Intestinal spirocheteosis in a patient with celiac disease

A young girl presented to us with recurrent diarrhea along with a history of 5 kg weight loss in one year. On examination, she appeared pale, while her laboratory reports showed a low hemoglobin, mean corpuscular volume [MCV] and serum albumin. Her erythrocyte sedimentation rate [ESR] was slightly raised with her iron profile suggestive of iron deficiency anemia. Viral markers, human immunodeficiency virus [HIV] serology along with thyroid profile were all unremarkable. There was no history of tuberculosis, and purified protein derivative [PPD] skin test was also negative. Computed tomography [CT] abdomen showed thickening of the terminal ileum with multiple enlarged lymph nodes. An esophagogastroduodenoscopy [EGD] along with colonoscopy was done. Multiple biopsies were taken, which were suggestive of sprue along with intestinal spirochetosis. Her tissue transglutaminase [TTG] was negative while deamidated gliadin peptide [DGP] was positive. She was kept on gluten-free diet and started on tablet metronidazole. This case shows that intestinal spirochetosis should be kept in mind in patients belonging to lower socio-economic status, who present with chronic diarrhea symptoms

Hepatic Sarcodosis presenting as portal hypertension in a young boy

A 13-year-old boy, known case renal stone disease came with the complaints of abdominal pain along with low grade fever. On examination, hepatosplenomegaly was noted while his lab reports showed a low hemoglobulin with a raised ESR. His blood and urine cultures showed no growth. Viral markers, autoimmune profile, C and p ANCA were all negative apart from a raised serum IgG level. Ultrasound abdomen showed a hyperechoic liver with an enlarged spleen along with splenic varices and minimum ascites. Ultrasound hepatic doppler was normal. Serum AFP levels were normal while workup for Wilson's disease was negative. Fibroscan showed F4 fibosis. CT scan abdomen showed an enlarged left lobe of the liver along with an enlarged spleen. His EGD revealed varices. So liver biopsy was done that was suggestive of chronic granulomatous disease with ZN stain testing negative for TB.PPD, urine for AFB were both negative. Serum ACE levels were raised. He started ATT therapy but his condition did not improve. So, on the suspicion of hepatic sarcoidosis, he started on steroids and had a drastic improvement in his condition

use of Karnofsky Performance Status [KPS] as a predictor of 3 month post discharge mortality in cirrhotic patients

Aim: Is Karnofsky Performance Status [KPS] a predictor of 3 month post discharge mortality in cirrhotic patients?

Background: Cirrhotic patients often experience an abrupt decline in their health, which often leads to frequent hospitalization and can cause morbidity and mortality. Various models are currently used to predict mortality in cirrhotics however these have their limitations. The Karnofsky Performance Status [KPS] being one of the oldest performance status scales, is a health care provider - administered assessment that has been validated to predict mortality across the elderly and in the chronic disease populations

Methods: We used the KPS performance status scale to envisage short-term mortality in cirrhotic and HCC patients who survive to be discharged from hospital

Results: Our study showed that KPS one week post-discharge, child pugh score, hospital stay, international normalized ratio, serum albumin, total bilirubin and serum creatinine showed statistical significance on univariate analysis. On multivariate analysis, KPS was found to be statistical significant predictor of 3-month mortality

Conclusion: Hence KPS can be utilized to identify cirrhotic patients at risk of 3-month post discharge mortality

Axillary artery aneurysm

Axillary artery aneurysm is a rare condition. Though mostly asymptomatic, it should be treated early as it can develop thrombosis, distal embolisation, pressure symptoms or rupture. We report here a case of a 24-year woman who presented with neurological deficit in her arm because of pressure by axillary artery aneurysm. Standard treatment of these aneurysms is excision and replacement with an interposition graft. We used reversed saphenous vein as interposition graft between axillary and brachial artery

This study helps to identify the common diseases encountered during Hajj Medical Mission and may aid in the better preparedness of such missions in future

Evaluation of different formulations of IGRs against Aedes albopictus and Culex quinquefasciatus (Diptera:Culicidae)

Objective: To test the relative efficacy of pyriproxyfen and methoprene on mortality, deformity, inhibition and emergence to adult stages of Culex quinquefasciatus and Aedes albopictus. Methods: Serial dilutions (0.01–0.05 mg/L) of methoprene, pyriproxyfen 0.5 water dispersible granules (WDG) and pyriproxyfen 1.0 WDG were used to assess mortality and inhibition of 3rd instar larvae of Aedes albopictus and Culex quinquefasciatus. Each concentration and control was replicated four times in completely randomized design. Data on larval mortality, growth inhibition, deformities and adult's emergence was recorded weekly. On the basis of best comparative performance, the efficacy of pyr-iproxyfen 1.0 WDG at 0.1 g/m3 was also tested in the field by collecting treated water samples monthly for 1–6 months after field application. Twenty five 3rd instar larvae of Aedes and Culex spp. of the same cohorts were used for bioassays and compared with larvae in control cups containing 1 L of untreated tap water. Results: Results revealed variations in fatality of different insect growth regulators (IGRs) to the 3rd instar larvae of Culex and Aedes mosquitoes. Among the IGRs, pyr-iproxyfen 1.0 WDG was found best that exhibited significantly high emergence inhibition against Culex and Aedes spp. Based on the results, the IGRs were classified in terms of the tested parameters in order of pyriproxyfen 1.0 WDG > pyriproxyfen 0.5 WDG > methoprene. In case of field studies, pyriproxyfen 1.0 WDG, pool data of the entire target treated sites showed minimum adult emergence from water sampled of habitats treated with 0.1 g/m3 of pyriproxyfen 1.0 WDG. Conclusions: It is thus concluded that IGRs can be utilized as environment friendly control measures for Culex and Aedes spp. of mosquitoes on small and large scale. This will reduce the use of conventional insecticides by the public health authorities and help in reducing selection pressure of insecticides.

Double flap patch closure of VSD with elevated pulmonary vascular resistance: an experience at AFIC/NIHD

To determine the 30 days outcome measured in terms of morbidity and mortality in cases of ventricular septal defect [VSD] with increased pulmonary vascular resistance [PVR] managed with double flap patch closure. Case series. Armed Forces Institute of Cardiology [AFIC/NIHD], Rawalpindi, from December 2005 to December 2008. Forty patients with VSD having PVR 9.58 + 4.33 wood units underwent double flap patch closure. The patch was fenestrated as one half of the expected aortic annulus diameter. A separate flap patch 5 mm larger than fenestration was attached to superior upper one third margins of fenestration. The patch was placed with flap to open towards the left ventricular apex. Modified ultra filtration [MUF] was employed in every case and sildenafil was given postoperatively. The age of patients ranged from 1 to 28 years with a mean of 6.66 + 5.70 years. There were 22 males and 18 females. All patients were weaned off from inotropic and ventilatory support as earlier as possible postoperatively with intensive care unit [ICU] stay of 77.15 + 54.56 hours. Postoperative pulmonary artery pressures were reduced to 42.63 + 10.86 mmHg as compared to pre-operative pulmonary artery pressures of 88.3 + 15.2 mmHg. Postoperatively 11 patients with suprasystemic pulmonary artery pressures and desaturation went into pulmonary hypertensive crisis in which immediate 2D echo evidenced the functioning flap valve with right to left shunt. There was only one death [early] out of 40 patients with an overall mortality of 2.5% along with limited morbidity. Double flap patch is an inexpensive, easy to construct technique with low morbidity and mortality in cases of VSD with raised PVR

Helicobacter pylori detection in chronic gastritis: a comparison of staining methods

Background: Helicobacter pylori is an important cause of chronic gastritis, gastric ulceration and gastric malignancies as gastric carcinoma and MALT lymphoma. Its definitive diagnosis is based on histopathology. Routine H and E stain is not very effective in its detection, immune-stains and fluorescent stains are costly. Need for simple cheap and sensitive stain has always been a topic of hot debate and extensive research. Method: paraffin embedded blocks of all adult patients diagnosed as chronic gastritis/gastric ulceration with no accompanying gastric pathology as hypertrophic gastropathys, and neoplasias were taken into study. Three sections of 4 micron were cut and stained with routine H and E, Giemsa, and Cresyl fast violet. Results: Total number of patients was 50. Out of these 37 [74%] were males and 13 [26%] were females. Mean age of the patients was 50.4 years. Thirty-four percent [34%] were positive in normal H and E stain, 68% were positive in Giemsa and 76% were positive in Cresyl fast violet. Conclusion: Cresyl fast violet is a good stain for diagnosis of H. pylori gastritis. Keywords: H pylori, chronic gastritis, H pylori staining methods
