Abstract
Immunoaffinity chromatography (IAC) is a fundamental isolation and purification tool which is incorporated in a substantial range of therapeutic and diagnostic applications. This study has reappraised the usefulness of immunoaffinity chromatography for the purification of polyclonal antibodies. Protein A based IAC is a convenient and reliable method for purification of IgG, from hyperimmunesera (HIS) raised in experimental animals such as rabbits, guinea pigs and mice to be utilized in pharmaceutics and diagnostics. The 146S fraction of Foot and Mouth Disease virus (FMDV) TCID50=10 5.6 was cultured on a baby hamster kidney cell line 21 (BHK-21), concentrated using salt precipitation method using PEG 6000, purified by size exclusion chromatography (SEC) using Sepharose-30 at 254nm absorbance. Purification of 146S FMDV was analyzed using 12% SDS-PAGE which provided two bands of light and heavy chains. The alum-based vaccine, consisting of ≥10μg of 146S FMDV, was applied in 10 male rabbits and 10 male guinea pigs and two animals of each group were taken as a negative control. The titer of serum was calculated using virus neutralization test. A Protein-A kit (Thermo scientific- 44667, 0528.2) was used to purify HIS raised against 146S FMDV and validated using 12% SDS PAGE in reducing condition. The data demonstrate that protein-A affinity chromatography is an efficient tool for the purification of antibodies from hyper-immune sera raised against 146S FMDV and can be used for the production of diagnostic kits e.g. Enzyme linked immuno-sorbent assay (ELISA) and radioimmunoassay.

Abstract
Due to the lack of farm-gate milk processing facilities, dairy farmers have to sell raw milk, resulting in economic and quality compromises. The study compared the quality of yogurt processed in solar assisted yogurt processing unit with the existing milk value chain and its techno-economic feasibility. For this, an investigation of the experiment was executed where four different milk processing approaches were compared. The quality attributes for processed milk like fat (5.283%), solid-not-fat (9.0833%), salts (0.6833%), protein (3.8%), lactose (4.1%), total solids (14.383%), pH (6.87), density (1.031 kg/L) and freezing point (- 0.532 °C) were found within the standardized ranges. Similarly, for the case of yogurt, these attributes were found as fat (5.5%), solid-not-fat (8.683%), acidity (0.93%), lactose (4.73%), total solids (14.183%), pH (4.3433), density (1.039 kg/L) syneresis (9.87 mL/100 g), S. thermophilus count range (10.18-10.30 log cfu/mL) and L. bulgaricus count range (10.26-10.34 log cfu/mL). Moreover, no detection of coliform count in solar-processed yogurt, endorsed the current idea to perform three processes of heating, fermentation, and cooling in a single unit. Based on the energy sources utilized, the payback period was calculated to be 1.3-9 years with an expected lifespan of 15 years while in terms of product profit, the payback period was predicted to be 1.78 years. The processing cost per liter of milk for yogurt production was calculated to be 0.0189 USD. Considering CO2 emission savings, it is anticipated that a solar-powered yogurt processing unit can generate 107.73 MWh of useful energy during its operating life with zero CO2 emission.

Abstract
Abstract
Study question
To access successfulness of sperm retrieval by evaluating the mRNA expression profile of JMJD1A, TNP1, TNP2, PRM1 and PRM2 in patients undergoing surgical sperm retrieval procedure.
Summary answer
Probability of sperm retrieval in azoospermia is decreased when mRNA expression profile of JMJD1A TNP2 and PRM2 in testicular tissue is decreased.
What is known already
Studies have been done on expression of JMJD1A in non-obstructive azoospermic patients in other part of the world with smaller sample size but this is the first study in Pakistan with larger number of patients. Study design, size, duration: Crossectional study, 100 azoospermic patients coming for purpose of sperm retrieval by TESE or micro-TESE in Australian Concept Infertility Medical Center, Karachi,from March, 2018 to December, 2019
Participants/materials, setting, methods
All recruited azoospermic patients were evaluated by history, physical examination, and hormonal assessment. RNA was extracted by pureLink RNA Micro kit and mRNA expression of the JMJD1A, TNP1, TNP2, PRM1 and PRM2 genes was determined using innu-SCRIPT One Step RT_qPCR SyGreen kit. For quantitative variables independent t test and for categorical variables chi-square/ Fisher Exact test was used. Unadjusted and adjusted prevalence ratio were reported by using cox regression algorithm. Main results and the role of chance: The patients were categorized into (i) Group-I: Patients with successful sperm retrieval n = 42, (ii) Group-II: Patients with unsuccessful sperm retrieval n = 58. The patients were categorized into (i) Group-I: Patients with successful sperm retrieval n = 42, (ii) Group-II: Patients with unsuccessful sperm retrieval n = 58. Azoospermic men in the successful sperm retrieval group had significantly decreased expression of JMJD1A (P < 0.001), TNP2(P < 0.001), and PRM2 (P 0.008). In addition to this regarding hormonal parameters: FSH (P 0.004), LH(P < 0.001), TSH(P<.011) were significantly different in azoospermic men with successful and unsuccessful sperm retrieval. In multivariate analysis, after adjusting for the other covariates, a significant association was found between JMJD1A, TNP2, PRM2 and successful sperm retrieval (p-value <0.05).
Limitations, reasons for caution
It is unicentric and outcomes for fertilization were not assessed. Azoospermic patients from multi-centeres were difficult because of lack of facility of sperm retrieval procedures at these centers and it was difficult to follow the fertrilization outcome.
Wider implications of the findings: This will be useful for making the decision in azoospermic men to proceed for ICSI or not. In addition to this, the repetition of unnecessary surgical procedures can be avoided, as the azoospermic men often undergo number of rounds of ICSI, with the hope of becoming biological father.

Abstract
Meloidogyne graminicola threatens global rice production, yet is understudied for many areas where it is cultivated. To better understand the prevalence and incidence of M. graminicola in central Punjab, Pakistan, we carried out field surveys of rice fields in the districts of Faisalabad and Chiniot. M. graminicola isolates were recovered from soil and root samples and identified on the basis of perineal patterns and rDNA ITS-based sequencing. The severity of nematode attack on rice roots and infested fields at various locations was based on galling index, root-knot nematode juveniles per root system, juveniles per 100 ml of soil, and prevalence of stylet-bearing nematodes and non-stylet-bearing nematodes. Maximum prevalence (22.5 and 27.5%) and minimum prevalence (17.5 and 20%) of M. graminicola was observed in Chiniot and Faisalabad, respectively. Eleven alternate host-plant species were examined in this study revealing varying degrees of M. graminicola infestation. ITS sequencing and phylogenetic analysis indicated that isolates from this study form a well-resolved clade with others from Asia, while another isolate falls outside of this clade in an unresolved polytomy with those from Europe and South America. Though monophyletic with the other M. graminicola, the isolates from Pakistan are distinguished by their high genetic variability and long branch lengths relative to the other isolates of M. graminicola, suggesting Pakistan as a possible ancestral area. Our results indicate that rice is severely attacked by a genetically diverse and aggressive M. graminicola, necessitating the development of appropriate control measures for its management in rice and other graminaceous crops.

Abstract
Aim To assess and correlate three distinct states of severely painful endodontically derived inflammation with their depiction on periapical radiographs using periapical index (PAI) scores. Methodology During a period of 15 months, 368 consecutively enrolled patients with suspected endodontic emergency conditions were examined at the University of Zurich, Center of Dental Medicine. Cases with a severely painful (numeric rating scale, NRS‐11 > 6) endodontically involved tooth and a clear pulpal and apical diagnosis (n = 162) were selected (one tooth per patient). Teeth were divided into three groups according to the clinically diagnosed main location of the inflammatory process: level 1: pulp (positive response to cold test), level 2: periodontium (no response to cold without swelling) and level 3: periapical tissues (no response to cold with swelling). Periapical radiographs were obtained using a digital unit and analysed by two calibrated observers. For level 2, which had the highest PAI variance (n = 76), the PAI scores were further scrutinized regarding their dependence on tooth location and the duration of pain. Data were analysed using chi‐squared and non‐parametric tests, alpha = 0.05. Results Overall, the PAI scores correlated well with the clinically diagnosed main location of periapical inflammation (Spearman’s rho = 0.5131, P < 0.001), with level 1 having the lowest scores by far (P < 0.001) and level 2 having significantly lower scores compared to level 3 (P < 0.05). However, a PAI score of 5 was found in merely 3 teeth within the entire cohort, and 49% of the teeth in the level 2 group had no radiolucency (PAI < 3). Within level 2, the PAI scores were not dependent on tooth location but were substantially (P < 0.001) higher for teeth which had hurt for more than one week, and for root filled teeth. Conclusions For the analysed, severely painful endodontically involved teeth, the clinically diagnosed main location of inflammation was reflected by the periapical index. PAI scores were not significantly influenced by anatomical noise, yet in some cases under‐estimated the clinical situation.

Abstract
Wheat yellow/stripe rust pathogen Puccinia striiformis is highly diverse and recombinant in the north of Pakistan in the Himalayan region. However, little is known about the role of this diversity in disease epidemics in areas where wheat yellow rust is an important disease in both irrigated and rain-fed wheat (i.e., in the plains of Pakistan). We explored the population diversity in P. striiformis during the rust epidemics of 2013 in the major wheat-growing regions of Pakistan (the Himalayan region, central Khyber Pakhtunkhwa [KP], southern KP, central and northern Punjab). Disease severities among commonly grown cultivars ranged from 5% to 100%. Microsatellite genotyping with 16 simple sequence repeat (SSR) markers revealed a high diversity among 266 isolates collected during the season, with the Simpson diversity index (Simpson 1949) ranging from 0.870 (Himalayan) to 0.955 (southern KP). The recombination signature was stronger in the Himalayan population and central KP compared with wheat-growing regions of Punjab and southern KP. The overall diversity was higher in Pakistan relative to the clonal populations present in Europe, Australia, and the Americas. Analyses of population subdivision revealed no clear evidence of spatial structure for samples from Pakistan, with a maximum fixation index (FST) value of only 0.10. The lack of clear population subdivision could be attributed to migration of pathogen. In turn, the high diversity of P. striiformis in Pakistan represents a potential threat to wheat production in the region and worldwide, as a possible source to found clonal populations in diverse wheat-growing areas.

Abstract
Background:Corneal melt is a rare inflammatory disease of the peripheral cornea; it may lead to perforation of the globe and visual failure. Corneal melt can be a manifestation of systemic vasculitis in patients with RA and other conditions, such as cancer. Without early and aggressive treatment it may be associated with a poor visual outcome and a high mortality. It has been reported in patients with stable RA.Objectives:A case report in a patient with long standing but well controlled Rheumatoid Arthritis (RA) and metastatic disease.Methods:A 75 year old male with a background of sero positive Rheumatoid Arthritis for more than 10 years presented to the Eye Casualty with a two week history of a painful left red eye. His other medical history was significant for Stage IIB poorly differentiated cancer of the left lower lobe. Left lower lobectomy with a patch of diaphragm resected. Intratumoural lymphovascular invasion noted. He completed Adjuvant Carboplatin/Vinorelbine chemotherapy September, 2017. He had DVT proximal left leg 22ndof September, 2017. Follow up CT in 2018 demonstrated a right renal upper pole lesion for which he was awaiting biopsy with?metastatic lung disease vs primary renal carcinoma. His RA was well controlled on Methotrexate 10mg weekly. He had been treated by the ophthalmology team for left marginal Keratitis for the prior 2 months with steroid eye drops without significant improvement. On presentation to ED, he described sharp eye pain, waking him from the sleep, associated with watery discharge and photophobia. Examination showed corneal melt in left eye involving 25% of inferior portion of the cornea and spastic entropion with injecting eye lashes. He had no active joints and there were no other signs of vasculitis. CRP was 4.1. He had a negative ANA and ANCA; viral swabs were negative. He was admitted under the medical team. Intravenous Methyl Prednisolone was started. The patient felt better after 5 days of Methyl Prednisolone. Left temporary tarsorrhaphy was done by Ophthalmology. Cyclophosphamide was initiated after discussion with Oncologist pending the result of the renal biopsy. Patient was discharged after 5 days of admission in the hospitalResults:The renal biopsy was positive for metastatic Squamous cell carcinoma of lung. Cyclophosphamide was withdrawn and he was started on Carboplatin/Gemcitabine. The corneal melt improved with complete resolution of his visual symptoms.Conclusion:In this case, although the history of RA was felt by the ophthalmology team to be the most likely association with the corneal melt, we would argue the oncological diagnoses were likely the driving force behind the presentation.References:[1]Sule A, Balakrishnan C, Gaitonde S, Mittal G, Pathan E, Gokhale NS, et al.

Abstract
Abstract
Background: The use of titanium-coated polypropylene mesh (TCPM) is an alternative to a-cellular dermal matrix for the implant based breast reconstruction by providing extra implant coverage especially in the lower half. The aim of our study was to analyze short-term outcomes of TCPM based implant breast reconstruction and compare the patient- and procedure-related factors to implant loss and surgical complications.
Methods: Between 2013and 2016, implant breast reconstructions after conservative mastectomies using TCMP was performed in 50 patients (with 58 reconstructions). Complications were divided into major (need for additional surgery), minor (conservative treatment), and implant loss. Univariate analyses were performed to determine the influence of the patient- and procedure-related factors on postoperative complications and implant loss.
Results: Fifty patients had therapeutic mastectomies with 8 of them also had contra lateral risk reducing mastectomies. With median follow-up of 17.5 months, four of 50 patients had implant loss. Reasons for implant loss were skin necrosis in 2 cases, infection in 1 case and necrosis with infection in another case. One of these patients had a revised reconstruction one year later. One additional patient required implant replacement because of capsule contracture. No risk factors were observed for patient-associated complications. Univariate analysis revealed an increased risk for implant loss in patients with skin necrosis (p < 0.01).
Conclusions: This titanium-coated polypropylene mesh shows acceptable complication rates and its use in immediate implant breast reconstruction is safe and effective.

Abstract
Municipal effluent of three rural settings of Islamabad was assessed for physicochemical and microbiological parameters by collecting wastewater from inlet and center of ponds. Results showed that water quality was comparatively better at the center as Typha latifolia plants were growing toward the center of ponds. In another study, the wastewater treatment ability of T. latifolia was investigated by growing them in industrial and municipal effluent under greenhouse conditions. Water and plant samples were collected periodically (3rd, 10th, 17th, 24th, and 31st day after transplanting) for the measurement of Pb, Cu, and Cd concentrations. A decrease in heavy metal concentration of both effluents was observed as the experiment progressed and metal removal percentages ranged between 81% and 96%. Complementary the increase in metal concentration in plant tissues was observed over experimental period. Among plant tissues, metal concentration of Pb was highest i.e. 362 mg kg-1 in roots and 313 mg kg-1 in shoots at end of experiment. Pb, Cu, and Cd concentrations were higher in roots than shoots and hence translocation factors were less than 1.0. Metal removal efficiency was better from industrial wastewater and was in order of Pb > Cu > Cd. T. latifolia can be used for remediation of heavy metal-polluted wastewater.

Abstract
AbstractAir heterogeneity in the drying chamber of the batch-type dryer is a major problem because uneven air distribution within the drying chamber reduces the product quality and dryer efficiency. To surmount this problem, a new dryer with central air distribution model has been designed and developed. This is the distinct design feature of the dryer, which ensure the uniformity in the moisture content of the final dried paddy grains. ANSYS-Fluent (Computational Fluid Dynamics [CFD]) was used to predict the flow behavior of the air with respect to pressure and velocity within the drying chamber by applying actual boundary conditions and standardk−εturbulence model. Pressure and velocity profiles in the drying chamber were determined using CFD to optimize the drying uniformity. An estimated value for velocity input was used and air distribution was found good. For the validation of simulation results several drying tests were performed at different dryer depths of 18, 36, 54 and 72 cm in the drying chamber. The drying results expressed as percentage moisture content reduction, along the length of the dryer and measured the uniformity in the drying rate. The drying curves for each depth showed highR2value. Numerical simulation and experimental results showed that the newly developed solar-assisted paddy dryer is capable to produce uniform air distribution throughout the length of the drying chamber in the dryer for uniform and quality drying. This approach improved the overall performance of the solar-assisted paddy dryer.

Abstract
Abstract
Background:
Axillary lymph node involvement is a prognostic factor in breast cancer and it is used to guide adjuvant therapy. Axillary clearance remains the standard of care in lymph node positive disease in most parts of the world. Usually this is performed as second procedure but immediate intra-operative node analysis allows clearance to be performed as part of the initial procedure where necessary.
The Metasin assay targets the breast epithelial cell markers CK19 and mammaglobin mRNA and detects the presence of breast tissue (metastatic disease) in the sentinel nodes. Evidence shows the Metasin assay to be fast (average assay time 41.2min) and accurate with a discordance rate below 4% compared with histology. The cost effectiveness of the assay has been reported in our previous studies.
Aim:
The aim of this study is to assess the risk of axillary recurrence following the use of the Metasin assay to guide axillary management.
Method:
This is a single centre retrospective study which included all patients presenting to a district general hospital with early clinically node negative breast cancer undergoing sentinel node biopsy between Oct 2011 and Dec 2014.
Alternate 2 mm slices of the node were examined intraoperatively using the Metasin assay and the remainder sent for histological examination. The results of the Metasin assay and histology were compared. The risk of axillary recurrence using the Metasin test to select patients for immediate axillary clearance was assessed.
Results:
1073 sentinel nodes from 545 patients were analysed during this three-year period. 2 patients were lost to follow up. 94 patients were node positive and underwent axillary clearance as part of their primary surgery. 449 patients had sentinel node biopsy with no further axillary procedure. There were 36 nodes (3.34%) with discordant results. Median follow up was 32 months (range 18 to 55 months).
Fourteen patients presented with recurrences (2.56%). The mean event free interval was 15 months. Of the 14 patients, 5 patients tested with Metasin had macrometastases and underwent immediate axillary clearance during the primary surgery. 7 patients were node negative and 2 patients were shown to have micrometastases. 11 patients recurred with distant metastases, 3 patients with local recurrence and 2 patients (0.36%) with axillary recurrences.
The two axillary recurrences occurred at 3 and 5 months after primary surgery. Both patients underwent Metasin intraoperative analyses of sentinel nodes which were negative. Subsequent histological examination confirmed no metastatic node involvement in one patient but micro-metastases in the other. Both of these patients had aggressive disease with local, axillary and distant metastasis and subsequently died of their disease.
Conclusions:
The Metasin assay is a reliable intraoperative test for sentinel node involvement and when used to guide surgical axillary management is associated with very low axillary recurrences (0.36% with a median follow up of 32 months).

Abstract
Abstract
Background:
In the Western World, it has been stated that breast cancers detected on a screening program are indolent. There have been many recent publications stating that breast screening is overdiagnosing and therefore overtreating patients with breast cancer. With the advent of genomic testing, it can now be determined which patients have an aggressive tumor requiring systemic chemotherapy. We therefore conducted a retrospective study in the UK on patients having oncotype DX testing in both screen detected and symptomatic cancers.
Materials and Methods:
Patients in our institution undergoing oncotype DX testing for invasive breast cancer which was ER positive and node negative were part of this study. The detection of the breast cancer was documented as either a screening case or a symptomatic one. The recurrence scores of the oncotype DX testing was then compared in the screening versus the symptomatic cohort.
Results:
155 patients were included in this study. They underwent Oncotype DX testing between 2008 to 2016. The age of the patients ranged from between 31 years to 78 years. Eighty-nine patients were reported to have a low recurrence score; 45 had an intermediate score; and 21 had a high result. Fifty eight patients were screen detected, while 97 patients were symptomatic presentations. In the screening population, 32 patients had a low recurrence score; 22 had an intermediate result and 4 had a high recurrence score resulting in the latter groups being considered for chemotherapy. In the symptomatic cohort, 57 had a low recurrence score; 23 had an intermediate result; and 17 had a high score.
Conclusion:
The results of our study depict that even patients in a screeining cohort will have a high number of intermediate recurrence scores and some with a high recurrence score. This shows that the hypothesis that screening detects a majority of breast cancers which are indolent not requiring further systemic treatment should be looked at again in light of our results with genomic testing.

Abstract
Abstract
Background: Prognostic factors have been used for years to determine the benefit of adjuvant chemotherapy in breast cancer. However, reporting of the size and grade of the tumor are affected by interobserver variability in reporting. This can result in a change in the results of adjuvant online and an impact on decision making of chemotherapy. On the contrary, genomic testing such as oncotype Dx is reproducible. The purpose of our study was to assess the effect of pathological discordance on the adjuvant online results on a cohort of patients who also underwent oncotype Dx testing.
Materials and Methods: A total of 143 patients' histologies were included in this study. The results of the Phase III WSG-Plan B trial concerning central vs. local grade discrepancy rates were utilized to randomly change the grade of the tumors. 61 percent of grade 1 cancers were upgraded to grade 2 and 2% upgraded to grade 3. 4 percent of grade 2 cancers were downgraded to grade 1 and 26% were upgraded to grade 3. 1 percent of grade 3 cancers were downgraded to grade 1 and 25% were downgraded to grade 2. Likewise, change was made in the size of the tumor in 20 percent of patients. 8 to 10mm, 18-20, 28-30, and 48-50mm changed to 11, 21, 31 and 51mm respectively. 11-13mm, 21-23, 31-33, and 51-53mm was changed to 10, 20, 30, and 50mm. Ten percent of patients had the ER and Her 2 status changed.
Results: The simulation results showed that when the grade was only altered, the spearman correlation of the predicted 10 year mortality on adjuvant online with the original data was significantly changed from 1 to a result of 0.788. When the changed size was additionally added, the coefficient was 0.836. With the altered ER status, the result was 0.749 and with the Her 2 change, the spearman correlation was minimally changed to 0.742. The scattergrams showed a large number of outliers when the alteration in size was added to the altered grade.
Conclusion: Our simulation study confirms that with minimal changes in the clinical parameters because of the lack of perfect correlation between pathologist's results, there is a significant difference in the 10 year predicted mortality on adjuvant online. This is one step further in understanding the lack of correlation between adjuvant online and oncotype Dx, and the inconsistency of chemotherapy decision making with the sole use of adjuvant online.

Abstract
Abstract
OBJECTIVE: Vacuum-assisted breast biopsy (VABB) has replaced surgical biopsy for the assessment of mammographic abnormalities that are not evident clinically and or on ultrasound examination. The aim of this study was to determine the indications for, and accuracy of, vacuum-assisted breast biopsy (VABB) performed using digital breast tomosynthesis (DBT) guidance. (Hologic® Dimensions, Affirm guidance and Eviva handsets).
MATERIALS AND METHODS:
Design: Retrospective medical record and histopathologic review.
Patients and method: We introduced DBT guided VABB in June 2014 having previously investigated such patients using the prone table technique. This is a review of the first 66 consecutive patients investigated using this technique up to April 2105.
The following information was reviewed: Indication for VABB, (mammographic classification M1-5, type of abnormality – calcifications/mass/distortion), complications of the procedure itself, (failure to complete, infection, haematoma), the result of the multidisciplinary team (MDT) review of imaging/pathologic correlation and the outcome for the patient.
RESULTS: In one case it proved impossible to locate the lesion and this patient has been excluded from further analysis. The mean age of the patients was 57 years (30-80years). VABB was proposed for patients with lesions initially reported as highly suspicious (M5) 4 patients (6%), suspicious (M4) in 18 patients (28%), intermediate (M3) in 37 patients (57%) or benign (M2) in 6 patients (9%). Mean size of the lesion was 13mm (range 3-100mm). Forty-four patients (68%) presented with micro calcifications, 14 (21%) with distortions in and 7 (11%) with masses.
There were no complications (infection or haematoma) that required further management following the procedure.
Review by the MDT agreed that all biopsies were adequate and removed representative tissue from the lesion (No B1s). Review showed that the histology was benign and consistent in 30 (46%) patients all of whom were discharged to routine screening. 19 (29%) cases were reported as B3 (ADH, flat atypia, LCIS or ALH) in whom all the calcifications had been removed in 13 (20%) and the patients discharged and 6 (9%) went to open biopsy for residual calcifications all of whom were benign on final analysis. There was one (1.5%) radial scar reported as B4 that went to open excision and proved benign. 15 (23%) proved malignant (B5a, B5b) and went on to definitive treatment (with one patient entered into the LORIS low risk DCIS trial).
The procedure is quicker, more accurate (related to the higher resolution and larger window of the receptor plate) and involves less radiation exposure (often involving only one DBT exposure) when compared to performing the same procedure on the Hologic Platinum prone table.
CONCLUSION: DBT-guided VABB is an accurate, convenient and safe procedure.

Abstract
Langerhans cell histiocytosis can involve single or multiple organ/tissue systems and may go undiagnosed for years until it enters the clinician's differential diagnosis framework. We report on a young patient who initially presented with diabetes insipidus and subsequently with pyrexia of unknown origin. She progressed from single system Langerhans cell histiocytosis to multisystem involvement and remains in long-term remission following chemotherapy.

Abstract
A series of experiments were conducted to assess the effectiveness of rhizobacteria containing 1-aminocyclopropane- 1-carboxylate (ACC) deaminase for growth promotion of peas under drought conditions. Ten rhizobacteria isolated from the rhizosphere of different crops (peas, wheat, and maize) were screened for their growth promoting ability in peas under axenic condition. Three rhizobacterial isolates, Pseudomonas fluorescens biotype G (ACC-5), P. fluorescens (ACC-14), and P. putida biotype A (Q-7), were selected for pot trial on the basis of their source, ACC deaminase activity, root colonization, and growth promoting activity under axenic conditions. Inoculated and uninoculated (control) seeds of pea cultivar 2000 were sown in pots (4 seeds/pot) at different soil moisture levels (25, 50, 75, and 100% of field capacity). Results revealed that decreasing the soil moisture levels from 100 to 25% of field capacity significantly decreased the growth of peas. However, inoculation of peas with rhizobacteria containing ACC deaminase significantly decreased the "drought stress imposed effects" on growth of peas, although with variable efficacy at different moisture levels. At the lowest soil moisture level (25% field capacity), rhizobacterial isolate Pseudomonas fluorescens biotype G (ACC-5) was found to be more promising compared with the other isolates, as it caused maximum increases in fresh weight, dry weight, root length, shoot length, number of leaves per plant, and water use efficiency on fresh and dry weight basis (45, 150, 92, 45, 140, 46, and 147%, respectively) compared with respective uninoculated controls. It is highly likely that rhizobacteria containing ACC deaminase might have decreased the drought-stress induced ethylene in inoculated plants, which resulted in better growth of plants even at low moisture levels. Therefore, inoculation with rhizobacteria containing ACC deaminase could be helpful in eliminating the inhibitory effects of drought stress on the growth of peas.

Abstract
BACKGROUND Peroxisome proliferator-activated receptor (PPAR)-gamma agonists have been proposed as therapy to lower plasma ACTH in Cushing's disease. Cyclical secretion of ACTH may, however, explain some of the responses seen. Patients with Nelson's syndrome have persistently high levels of ACTH and may be a better model for examining new therapies to elevated ACTH levels. OBJECTIVE The objective of the study was to assess whether high-dose rosiglitazone therapy reduces circulating ACTH levels in Nelson's syndrome, a model of ACTH hypersecretion for which no established medical therapy exists. DESIGN The design was an open-label, prospective, nonrandomized study over 14 wk. SETTING The study was conducted at a university teaching hospital. PATIENTS Six patients with Nelson's syndrome participated in the study. METHODS Patients were assessed at -2, 0, 4, 8, and 12 wk. Rosiglitazone 12 mg/d was administered between 0 and 8 wk. PPAR-gamma immunoreactivity was assessed in pathological tissue. OUTCOME MEASURE Plasma ACTH was measured before (0830 h) and 120 min after morning dosing with hydrocortisone (HC). RESULTS One female withdrew prior to commencing therapy for personal reasons. There was no evidence that ACTH levels changed over time (P = 0.864). The average ACTH level was 1187 ng/liter (95% confidence interval 928-1446) for patients before the HC dose and 432 ng/liter (95% confidence interval 172-692) after the HC dose. PPAR-gamma immunoreactivity was positive in three ACTH-secreting tumors available. CONCLUSIONS Rosiglitazone 12 mg/d did not change circulating ACTH over time, despite PPAR-gamma receptor expression in the tumor tissue. However, this does not preclude the possibility that other patients may respond or that higher doses of rosiglitazone or more potent agonists might prove useful treatment.

Abstract
Wernicke's encephalopathy, a serious neurological disorder caused by thiamine deficiency, is most commonly found in chronic alcoholics. We present a typical case of Wernicke's encephalopathy in a non-alcoholic man. Our patient presented with altered mental status, slurred speech, fever, vomiting and headache of one-week duration. An infectious etiology of the symptoms was ruled out by spinal fluid cultures. The patient improved dramatically within 24 hours of administration of thiamine.

Abstract
OBJECTIVE To analyse the results of the new revolutionary technique of Intra Cytoplasmic Sperm Injection (ICSI) for male infertility. Furthermore, to find out the ways of reducing cost of the expensive methods of Assisted Reproductive Techniques. DESIGN This is an analytical study of results of 71 patients (86 Cycles) of ICSI performed in first year of its launching in Baqai Institute of Reproduction and Developmental Sciences (BIRDS) from May 1997 to April 1998. Men with semen reports of parameters less than WHO criteria were treated including Azoospermic men. RESULTS After ICSI procedure a fertilisation rate of 58.9% was achieved in 86 cycles. A total of 17 clinical pregnancies were had from the transfer of fresh embryos. This includes three pregnancies from Surgical Sperm Collection in azoospermic men. Cost could be reduced by avoiding high dosage of drugs and by cutting out serial serum estrogen levels. Ultrasonic assessment for follicle monitoring is equally satisfactory. CONCLUSION ICSI proved to be the only successful treatment for men with poor semen quality. It is giving nearly 20% chances of fatherhood in a man who was labeled infertile previously. Results are promising and will be improving with time. The cost could be reduced to an extent by cutting down drug doses and laboratory investigations without compromising the results.

Abstract
A 41-year-old woman had fever of 3 days' duration. She had had pancreas transplantation 2 years previously and had recently completed a course of antirejection medication. Temperature spikes occurred during treatment with broad spectrum antibiotics. No obvious cause for the fever was found. The patient's condition worsened, with development of shortness of breath, bilateral pulmonary infiltrates on chest radiographs, sepsis, and shock. Fiberoptic bronchoscopy with bronchoalveolar lavage showed the presence of Toxoplasma gondii. Pyrimethamine and clindamycin were started, and the patient improved. Toxoplasma gondii occurs in contaminated food containing oocysts or cysts. Organ transplantation and blood transfusions are other routes of transmission. Most recent cases have occurred in human immunodeficiency virus (HIV) patients with reactivation of previous infection. Serology and tissue biopsies are used for diagnosis. Treatment includes a combination of pyrimethamine and sulfadiazine or trisulfapyrimidines.
