Abstract
The study of anthropoid nonhuman primates has provided valuable insights into frontal cortex function in humans, as these primates share similar frontal anatomical subdivisions (Murray et al. 2011). Causal manipulation studies have been instrumental in advancing our understanding of this area. One puzzling finding is that macaques with bilateral aspiration removals of orbitofrontal cortex (OFC) are impaired on tests of cognitive flexibility and emotion regulation, whereas those with bilateral excitotoxic lesions of OFC are not (Rudebeck et al. 2013). This discrepancy is attributed to the inadvertent disruption of fibers of passage by aspiration lesions but not by excitotoxic lesions. Which fibers of passage are responsible for the impairments observed? One candidate is cholinergic fibers originating in the nucleus basalis magnocellularis (NBM) and passing nearby or through OFC on their way to other frontal cortex regions (Kitt et al. 1987). To investigate this possibility, we performed unilateral aspiration lesions of OFC in three macaques, and then compared cholinergic innervation of the anterior cingulate cortex (ACC) between hemispheres. Histological assessment revealed diminished cholinergic innervation in the ACC of hemispheres with OFC lesions relative to intact hemispheres. This finding indicates that aspiration lesions of the OFC disrupt cholinergic fibers of passage, and suggests the possibility that loss of cholinergic inputs to ACC contributes to the impairments in cognitive flexibility and emotion regulation observed after aspiration but not excitotoxic lesions of OFC.

Abstract
The efficient removal of organic contaminants from wastewater is, nowadays, a prominent area of study due to its biological as well as environmental significance. Antibiotics are now found in wastewater because of their high use, which has become a source of aquatic pollution. These antibiotics have dangerous implications for people’s health. Hence, effective pharmaceutical removal from wastewater and contaminated water bodies, especially the removal of antibiotics, is of major interest to global research organizations. This is why it is necessary to investigate this class of toxic material in wastewater discharge. We synthesized three different coordination polymers (CPs) in the presence of various assistant carboxylate linkers, namely, [Zn(Hbtc)(dip)]n (1), [Zn4(1,2-bdc)4(dip)4]n (2), and [Zn(1,4-bdc)(dip)]n (3) (3,5-di(1H-imidazol-1-yl)pyridine = dip, 1,3,5-benzenetricarboxylic acid = H3btc, 1,2-benzenedicarboxylic acid = 1,2-H2bdc, and 1,4-benzendicarboxylic acid = 1,4-bdc). These CPs were characterized by using different techniques, including single-crystal X-ray diffraction. The structural studies demonstrated that in 2, there are four Zn(II) centers and both centers are in different coordination environments (Zn2 has distorted tetrahedral geometry, whereas Zn1, Zn3, and Zn4 have square pyramidal geometry). Hirshfeld surfaces analysis revealed that different types of intermolecular interactions (C⋯C, H⋯C, H⋯H, O⋯C, N⋯H, and O⋯H) are present in the synthesized CPs. We examined the different antibiotics, such as metronidazole (MDZ), nitrofurazone (NFZ), dimetridazole (DTZ), sulfasalazine(SLA), and oxytetracycline (OXY), degradation behaviors of the synthesized CPs, which showed remarkable degradation efficiency. 1 showed photocatalytic behavior toward the NFZ antibiotic in an aqueous media. This study also showed that these catalysts are stable and reusable under mild conditions.

Abstract
INTRODUCTION The aim of our study was to assess the clinical outcome of isolated lymph node recurrence in patients with epithelial ovarian cancer treated by surgery and to analyze the impact of various clinico-pathological factors on prognosis. MATERIAL AND METHODS We conducted a retrospective analysis of all the epithelial ovarian cancer patients who underwent secondary lymphadenectomy surgery for isolated lymph node recurrence at our institute from 2013 to 2020. Univariate analysis of various factors influencing the post-recurrence disease free survival and post-recurrence survival was done using Kaplan-Meier for categorical variables and cox-proportional hazard progression for continuous variables. RESULTS A total of 21 patients of isolated lymph node recurrence were treated surgically during the study period. The median disease free interval to develop lymph nodal recurrence was 13 months. All the patients achieved complete resection to no gross residual disease without any significant morbidity associated with the procedure. The median post-recurrence disease free survival after treatment of lymph node recurrence was 25 months with 3-year post-recurrence survival of 72% and 3-year overall survival of 85%. Amongst the factors influencing post-recurrence disease free survival, young age (< 50 years), para-aortic lymph node dissection at initial surgery and single site of lymph node recurrence were significantly associated with better prognosis. A single site of lymph node recurrence was associated with significantly better post-recurrence survival. CONCLUSIONS Complete resection is feasible for epithelial ovarian cancer patients presenting with isolated lymph node recurrence, without any significant perioperative morbidity. When combined with postoperative adjuvant chemotherapy, complete resection is associated with favourable survival outcomes. Young age, para-aortic lymph node dissection during primary surgery and single site of lymph node recurrence are associated with better prognosis.

Abstract
A Biobank/Biorepository is an organized collection of resources that can be accessed to retrieve biological material and data for research purpose. Human specimen repositories (adult and paediatric) take lead amongst the various types of biorepositories. Patient's bio samples are a rich source of genetic information and therefore can form the basis of diagnostics, forensics and multidimensional disciplines of biomedical research. The advent of molecular techniques and the technological upsurge in the management of genetic resources has facilitated the human DNA sampling and data collection leading to the emergence of DNA banking. DNA banking has paved a new path in precision oncology and personalized medicine. This article highlights the current scenario concerning the general awareness, scientific consciousness and current national and international practices being initiated and in practice for the establishment of bio banking facilities particularly DNA bio banking.

Abstract
PURPOSE There is a growing evidence showing that there are geographic differences in hepatocellular carcinoma (HCC). Little is known about the characteristics of hepatocellular carcinoma in the Arabian Peninsula. The present study examines the presentation and outcomes of HCC in a single institution. METHODS A retrospective chart review of patients presented with advanced-stage HCC to Kuwait Cancer Control Center (KCCC) between 2008 and 2018 was conducted. Data collected included patients demographics, HCC risk factors, performance status, Child-Pugh score, pick up of sorafenib, and survival. RESULTS About 111 cases were analyzed. The mean age of the cohort was 61.8 ± 11.4 years and 94 patients (84.7%) were males. HCV and diabetes were the most common risk factors for HCC and presented in 60 patients (54.1%) and 45 patients (40.5%), respectively. About 78 (70.3%) patients had an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 at presentation. Only 29 (26.1%) patients presented with Child-Pugh class A, while 42 (40.4%) patients received sorafenib. The median overall survival was only 3 months. CONCLUSIONS In our cohort, HCV and diabetes were the main risk factors for HCC. The majority of patients was not amenable to sorafenib treatment and carries a very poor prognosis.

Abstract
It is known that the organic units in hybrid halide perovskites are free to rotate, but it is not clear if this freedom is of any relevance to the structure-property relationship of these compounds. We have employed quasi-elastic neutron scattering using two different spectrometers, thus providing a wide dynamic range to investigate the cation dynamics in methylammonium lead bromide (MAPbBr3) and formamidinium lead bromide (FAPbBr3) over a large temperature range covering all known crystallographic phases of these two compounds. Our results establish a plastic crystal-like phase forming above 30 K within the orthorhombic phase of MAPbBr3 related to 3-fold rotations of MA units around the C-N axis with an activation energy, Ea, of ∼27 meV, which has no counterpart in the FA compound. MA exhibits an additional 4-fold orientational motion of the whole molecule via rotation of the C-N axis itself with an Ea of ∼68 meV common for the high-temperature tetragonal and cubic phases. In contrast, the FA compound exhibits only an isotropic orientational motion of the whole FA unit with Ea ≈ 106 meV within the orthorhombic phase and a substantially reduced common Ea of ∼62 meV for the high-temperature tetragonal and cubic phases. Our results suggest that the rotational dynamics of the organic units, crystallographic phases, and physical properties of these compounds are intimately connected.

Abstract
Abstract
Introduction/Objective
Myeloid sarcoma within the central nervous system is a rare presentation of an infiltrative mass of immature myeloid cells. It is typically found in association with myeloid dysplastic syndrome, myeloproliferative disorder, or acute myeloid leukemia. Rarely, it can occur in the absence of these diseases.
Methods
We present the case of 68-year-old female with worsening nausea and headaches. Brain MRI showed diffuse pachymeningeal enhancement with numerous nodular enhancing extra-axial masses overlying both cerebral hemispheres.
Results
Open biopsy of these masses showed gelatinous, hemorrhagic, brown tissue measuring 3.0 x 2.0 x 0.7 cm. Histologically, the specimen shows a diffuse polymorphous atypical myeloid proliferation consisting of all three cell lineages. There are nodules composed predominantly of large blastoid cells with 1 to 2 prominent oblong nucleoli, consistent with erythroblasts and early erythroid precursors. In between the nodules there are myeloid cells in different stages of maturation, including numerous eosinophilic precursors. Scattered megakaryocytes are also identified.
Immunohistochemistry shows positivity for E-cadherin, CD235a and spectrin which highlight the immature erythroid cells. MPO, muramidase, and CD33 are positive in myeloid elements. Eosinophilic peroxidase highlights numerous eosinophilic precursors. CD34 is positive in the endothelial cells and very rare hematopoietic cells. CD20 and PAX 5 highlights B-cells, CD3 highlights T-cells, and CD4 highlights monocytic precursors, monocytes, histiocytes and a subset of T-cells.
Conclusion
Additional work up at the time of biopsy including FLOW cytometry and bone marrow biopsies showed no evidence of hematologic pathology. In summary the histologic and immunohistochemical findings demonstrate a tumor composed of proliferating immature myeloid cells most consistent with myeloid sarcoma without any evidence of hematological disease.

Abstract
Aims The prevalence of premature coronary artery disease (CAD) in India is two to three times more than other ethnic groups. Untreated heterozygous familial hypercholesterolemia (FH) is one of the important causes for premature CAD. As the age advances, these patients without treatment have 100 times increased risk of cardiovascular (CV) mortality resulting from myocardial infarction (MI). Recent evidence suggests that one in 250 individuals may be affected by FH (nearly 40 million people globally). It is indicated that the true global prevalence of FH is underestimated. The true prevalence of FH in India remains unknown. Methods A total of 635 patients with premature CAD were assessed for FH using the Dutch Lipid Clinical Network (DLCN) criteria. Based on scores, patients were diagnosed as definite, probable, possible, or no FH. Other CV risk factors known to cause CAD such as smoking, diabetes mellitus, and hypertension were also recorded. Results Of total 635 patients, 25 (4%) were diagnosed as definite, 70 (11%) as probable, 238 (37%) as possible, and 302 (48%) without FH, suggesting the prevalence of potential (definite + probable) FH of about 15% in the North Indian population. FH is more common in younger patients, and they have lesser incidence of common CV risk factors such as diabetes, hypertension, and smoking than the younger MI patients without FH (26.32% vs.42.59%; 17.89% vs.29.44%; 22.11% vs.40.74%). Conclusion FH prevalence is high among patients with premature CAD admitted to a cardiac unit. To detect patients with FH, routine screening with simple criteria such as family history of premature CAD combined with hypercholesterolemia, and a DLCN criteria score >5 may be effectively used.

Abstract
Background India contributes 1.5–2 million annual confirmed cases of malaria. Since both parasites and vectors are evolving rapidly, updated information on parasite prevalence in mosquitoes is important for vector management and disease control. Possible new vector-parasite interactions in Goa, India were tested. Methods A total of 1036 CDC traps were placed at four malaria endemic foci in Goa, India from May 2013 to April 2015. These captured 23,782 mosquitoes, of which there were 1375 female anopheline specimens with ten species identified using morphological keys. Mosquito DNA was analysed for human and bovine blood as well as for Plasmodium falciparum and Plasmodium vivax infection. Results Human host feeding was confirmed in Anopheles stephensi (30 %), Anopheles subpictus (27 %), Anopheles jamesii (22 %), Anopheles annularis (26 %), and Anopheles nigerrimus (16 %). In contrast, Anopheles vagus, Anopheles barbirostris, Anopheles tessellates, Anopheles umbrosus and Anopheles karwari specimens were negative for human blood. Importantly, An. subpictus, which was considered a non-vector in Goa and Western India, was found to be a dominant vector in terms of both total number of mosquitoes collected as well as Plasmodium carriage. Plasmodium infections were detected in 14 An. subpictus (2.8 %), while the traditional vector, An. stephensi, showed seven total infections, two of which were in the salivary glands. Of the 14 An. subpictus infections, nested PCR demonstrated three Plasmodium infections in the salivary glands: one P. vivax and two mixed infections of P. falciparum and P. vivax. In addition, ten gut infections (one P. vivax, six P. falciparum and three mixed infections) were seen in An. subpictus. Longitudinal mosquito collections pointed to a bimodal annual appearance of An. subpictus to maintain a perennial malaria transmission cycle of both P. vivax and P. falciparum in Goa.

Abstract
INTRODUCTION Dual antiplatelet therapy with clopidogrel and aspirin is the current standard of care in the management of patients with coronary artery disease (CAD) and acute coronary syndrome (ACS). The variability in response to these antiplatelet agents may be due to the underlying genetic diversity. This study was designed to determine the resistance to aspirin and clopidogrel in Indian patients and to look for correlation, if any, with selected polymorphisms. METHODS Platelet function testing by light transmission aggregometry was performed on 72 patients with CAD/ACS who were stable on dual antiplatelet therapy (clopidogrel 75 mg OD and aspirin 150 mg OD) along with 72 controls. Aspirin resistance was considered as mean platelet aggregation ≥ 70% with 10 μm ADP and ≥ 20% with 0.75 mm arachidonic acid. Clopidogrel resistance was defined as <10% decrease from the baseline in platelet aggregation in response to ADP 10 μm and semi-response as <30% decrease from the baseline. Polymorphisms CYP2C19*2, *3, CYP3A5*3 and PLA1/A2 were genotyped. RESULTS We found 51.4% patients with inadequate response to clopidogrel (1.4% resistant and 50% semi-responders) and 5.5% patients semi-responders to aspirin, none being completely resistant. The genotype and allele frequencies of CYP2C19*2 and PLA1/A2 gene polymorphisms were significantly different between clopidogrel semi-responders and responders. Carriers of CYP2C19*2 and CYP3A5*3 showed diminished inhibition of platelet aggregation. No significant correlation was found between coronary events, type of coronary intervention with clopidogrel nonresponsiveness. CONCLUSION Unlike aspirin, a high proportion of partial responders to clopidogrel were identified. In an interim analysis on 72 Indian patients, a significant association was found between CYP2C19*2 and PLA1/A2 in clopidogrel semi-responders.

Abstract
Abstract
A statistical experimental design method known as the Taguchi method was utilized to optimize the injection molding processes of poly(butylene terephthalate) (PBT) and poly(trimethylene terephthalate) (PTT) blends. Impact strength was taken as the optimized property. The significant parameters included mold temperature, injection pressure, holding pressure, injection time and holding temperature. Results of the Taguchi analysis gave mold temperatures as major influencing factor on the impact strength. The optimal processing conditions were determined through the Taguchi method giving an increase of 13.7% in impact strength for the blend. Further analysis was done to distinguish the blends dependency on temperature. Differential scanning calorimetry curves indicated the presence of recrystallization peaks that were dependent on the temperature profile the sample had received prior to testing. Polarized optical microscopy was used to show the different sphereulitic growth patterns under varying isothermal conditions. It was seen that at 90°C sphereulitic growth contained pockets of different sized spereulites. AFM imaging was also used to indicate differences in blended polymer morphology.

Abstract
The impact of pretreatment anaemia on survival in individuals with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) co-infection is not known. Moreover, HCV treatment is offered less frequently to individuals with anaemia, due to haematological side effects of the treatment regimen. This study aimed to determine the effect of HCV treatment on survival among HCV/HIV co-infected individuals with pretreatment anaemia using the Electronically Retrieved Cohort of HCV-Infected Veterans (ERCHIVES). Individuals with HCV/HIV co-infection were included in current analyses. Participants were considered treated if they were prescribed ≥ 4 weeks of HCV treatment. All-cause mortality data were obtained using record linkage. Survival analyses were performed using Cox proportional hazard models. Among 5000 HCV/HIV co-infected individuals, 1671 (33.4%) had pretreatment anaemia. In a follow-up period of up to 7 years (19,500 person-years), individuals with anaemia had significantly higher mortality rate compared with those without anaemia [144.2 (95% CI: 134.5-154.7) vs 47.5 (44.0-51.2) per 1000 person-years, respectively]. Among individuals with anaemia, HCV treatment was associated with significantly lower mortality rate [66.6 (44.3-100.2) vs 149.6 (139.2-160.5) per 1000 person-years, for treated vs untreated, respectively]. Treatment remained associated with substantial survival benefit after taking into account the effect of multiple comorbidities (hazards ratio: 0.34, 95% CI: 0.21-0.62). These data suggest that HCV/HIV co-infected individuals with pretreatment anaemia have significantly higher mortality compared with those without anaemia. HCV treatment is associated with substantial survival benefit in this group. Additional studies are needed to determine strategies to improve HCV treatment rates among this group.

Abstract
PURPOSE To evaluate intracranial tuberculomas using quantitative magnetic resonance (MR) techniques such as T2 relaxometry, magnetization transfer (MT), and diffusion-weighted imaging (DWI). MATERIAL AND METHODS Thirty-three patients with intracranial tuberculomas (histologically confirmed in 22) were evaluated using proton density/T2-weighted, T1-weighted (with and without MT), and echo-planar diffusion-weighted imaging sequences. T2 relaxation times, MT ratios (MTR), and apparent diffusion coefficient (ADC) values were calculated from the center of the lesion, the periphery, perilesional edema, and contralateral normal white matter. The mean and standard deviation values of each variable were calculated and correlated using Pearson's test (P = 0.05). RESULTS The measured mean values of T2 relaxation time, MTR, and ADC in the center of lesions were 155.5 ms, 14.1, and 1.27 x 10(-3) mm(2)/s, respectively, compared to 117 ms, 23.72, and 0.74 x 10(-3) mm(2)/s in normal white matter, and a T2 relaxation time of 187.45 ms in normal gray matter. Significant inverse correlations were noted between T2 relaxation values and MTR (P<0.001) and between MTR and ADC (P = 0.046). Significant positive correlation was seen between T2 relaxation and ADC values (P = 0.03). CONCLUSION Intracranial tuberculomas are characterized by relatively short T2 relaxation times (compared to normal gray matter), decreased MTR, and mostly no restriction of diffusion. A combination of these quantitative parameters could be of help in the noninvasive diagnosis of tuberculomas.

Abstract
Severe malaria is invariably caused by Plasmodium falciparum. In India, both adults and children are affected by severe malaria. However, children are more prone for developing anemia and convulsions as manifestations of severe malaria, while acute renal failure and jaundice are more common among adults. Pregnant women are vulnerable to hypoglycemia, anemia and pulmonary complications. The case-fatality rate due to severe malaria is 10-15% in spite of therapy but it increases in the presence of renal failure or respiratory distress (pulmonary edema or ARDS). Of late, multi-organ failure and high mortality figures are being reported increasingly from different parts of India. Early diagnosis and prompt treatment will reduce the mortality due to malaria. Cerebral malaria should always be suspected in a patient with altered sensorium in a malaria-endemic area. However, other causes of unconsciousness such as encephalitis, meningitis or hepatic coma should also be excluded. Parenteral quinine is the mainstay of therapy. A recent multi-centric study has demonstrated the efficacy of intravenous artesunate in reducing the mortality by 30%. The usefulness of adjunct therapy is still controversial.

Abstract
INTRODUCTION Colloid cysts of the 3rd ventricle are relatively rare intracranial tumours, more so in children. They are benign tumours with excellent prognosis if diagnosed and treated early. METHODS A retrospective analysis of 18 cases of colloid cysts in children below 18 years, operated in our institution between September 1998 and November 2003 (5 years) was made. Clinical presentation, radiological findings, surgical approaches and outcome were analysed. RESULTS Age ranged from 7 to 18 years. The male-to-female ratio was 12:6. Headache and vomiting were the most common symptoms. Papilloedema was the most common clinical sign. Pre-operative CT showed a hyperdense non-enhancing lesion in the majority. Twelve patients underwent a transcallosal, 2 a transcortical and 4 an endoscopic approach. Ventriculoperitoneal shunts were done in 5 patients. Postoperatively 2 patients developed epidural haemorrhage which required evacuation. One patient was re-explored for symptomatic residue. A mean follow-up of 10.2 months was available in 9 patients; the majority were asymptomatic. CONCLUSION Colloid cysts though rare are increasingly detected in children. Their early recognition and treatment give excellent results.

Abstract
CASE REPORT Four cases of medulloblastoma with extensive nodularity (MBEN) are described. The patients were 3 years of age or younger at diagnosis. Cranial CT scan disclosed multiple coalescing nodules with peculiar 'grape-like' architecture in three patients. A near total excision of the tumour was performed in all four patients. The patients are currently receiving radiation and chemotherapy. Histologically, the tumours were characterized by extreme nodularity with intranodular uniformity and low proliferative index. The internodular zones were extremely cellular, composed of undifferentiated, mitotically active cells. Bcl-2 protein expression was observed in the cellular zones but was distinctly absent within nodules. DISCUSSION MBEN represents a variant that occurs in very young children but has a good prognosis. The favourable outcome is probably related to its spontaneous neurocytic differentiation. The pattern of Bcl-2 immunoreactivity in MBENs indicates that this protein could be a key player in the regulation of neuronal differentiation in medulloblastomas.

Abstract
AIMS The aim of this study was to establish whether nimodipine given orally soon after severe diffuse head injury for a period of three weeks improved outcome. MATERIAL AND METHODS The present report analyzes the results of a prospective randomized double-blind placebo-controlled trial of nimodipine in 97 severe head injury patients (GCS Score < or =8) treated at the Department of Neurosurgery, NIMHANS, between January 1995 and June 1996. The patients were randomly assigned to two groups which were matched for age, sex, mode of injury, time interval from injury to admission, neurological status and CT scan findings. One group was given nimodipine 30 mg Q6H and the other group was given a placebo. The outcome of these patients at 6 months was evaluated using the Glasgow Outcome Score by and a psychologist. RESULTS Results showed no significant difference in the functional and psychological outcome between the two groups, even in patients with subarachnoid hemorrhage. No adverse drug events were recorded. CONCLUSION Oral nimodipine given for three weeks does not improve outcome in patients with severe diffuse head injury.

Abstract
Transgenic lines of indica rice were generated by Agrobacterium-mediated transformation with the choline oxidase ( codA) gene from Arthrobacter globiformis. Choline oxidase catalyses conversion of choline to glycine betaine. Glycine betaine is known to provide tolerance against a variety of stresses. Molecular analyses of seven independent transgenic lines as performed by Southern, Northern and Western hybridization revealed integration and expression of the transgene as well as inheritance in the progeny plants. A good correlation was observed between levels of mRNA and protein accumulation, and a significant amount of choline oxidase product, i.e. glycine betaine, accumulated in R0 as well as R1 plants. Mendelian as well as non-Mendelian segregation patterns were obtained in the progeny plants. Challenge studies performed with R1 plants by exposure to salt stress (0.15 M NaCl) for 1 week, followed by a recovery period, revealed that in some cases more than 50% of the transgenic plants could survive salt stress and set seed whereas wild-type plants failed to recover.

Abstract
During our initial experience with endoscopic third ventriculostomies, we observed intraoperative bradycardia and postoperative hyperkalemia. The present study was carried out to verify the consistency of these initial observations. Intraoperative heart rate (HR) changes and postoperative serum K + changes were studied prospectively in 20 patients of endoscopic third ventriculostomy. Another 6 patients who underwent endoscopic procedures other than ventriculostomy acted as controls. The anaesthetic technique and intraoperative and postoperative fluid regimen were similar in all patients. Serum K + concentrations were measured intraoperatively and once a day for the next 5 days. The third ventriculostomy group exhibited a significant slowing of the heart rate during the fenestration of the floor of the third ventricle (112 +/- 26 to 101 +/- 28 bpm, p < 0.001) and also at the time of the reversal of the neuromuscular block at the end of surgery (104 +/- 29 to 96 +/- 33 bpm, p < 0.01). The control group did not exhibit similar changes in the heart rate. The postoperative increase in serum K + values in the ventriculostomy group (0.82 +/- 0.55 mmol/L) was higher than that in the control group (0.10 +/- 0.44 mmol/L) (p < 0.01). Endoscopic third ventriculostomy is associated with a significant bradycardia at the time of fenestration and at the time of reversal of the neuromuscular block. The procedure is also associated with a postoperative increase in serum K + values. We propose a mechanism involving distortion of the posterior hypothalamus, which accounts for the bradycardia and postoperative hyperkalemia.

Abstract
BACKGROUND The renewed interest in mitral valve replacement with a pulmonary autograft encouraged us to perform this procedure in selected patients. METHODS AND RESULTS From August 2000 to February 2002, 10 patients between 30 and 52 years of age with calcific mitral valvular disease underwent the Ross II procedure. Patients were either in New York Heart Association functional class III (7/10) or IV (3/10). Transthoracic echocardiography was done in all the patients to confirm the diagnosis. A pulmonary autograft was used to replace the diseased mitral valve. Intraoperative transesophageal echocardiography confirmed normal functioning of the autograft. There were 2 early deaths. The 8 survivors are in New York Heart Association functional class I with excellent autograft and homograft function at a follow-up of 2-20 months (mean 9 months). CONCLUSIONS This procedure is a viable option for mitral valve replacement in patients with calcific mitral valve disease. However, the procedure is technically demanding and requires a valve bank.

Abstract
Various surgical approaches to treat intraventricular cysticercosis have been practiced over the years. We now present our experience with the use of the endoscope in the removal of intraventricular cysticercal cysts in patients with intraventricular cysticercal lesions associated with hydrocephalus. From 1995 to 1998, we have excised intraventricular cysticercal cysts from 9 patients. They were located in lateral ventricle in 4, in the third ventricle in two and in the fourth ventricle in three patients. A Gaab's rigid neuroendoscope system was used to enter and excise cysts in the lateral and third ventricle. The flexible fiberoptic scope was used for excising cysts in the fourth ventricle, through a transaqueductal route. In all cases a precoronal frontal burr hole was used for entry. All have been treated with albendazole in the postoperative period. All the cysts were removed successfully using endoscopic neurosurgery alone. One patient had a superficial injury to the rigid side of the aqueduct with a postoperative deficit, which improved. Three septal perforations, three third ventriculostomies, and one aqueductoplasty were done in the same sitting after cyst removal for CSF diversion. None of the nine cases required further surgery up to date. The follow-up period varied from 12 to 45 months with a median of 18 months. Endoscopic neurosurgery is a minimally invasive technique enabling removal of intraventricular cyticercal cysts from all locations, avoiding major craniotomies/posterior fossa explorations and shunts.

Abstract
A population genetic study of chloroplast DNA was carried out in 23 wild populations of Prunus avium sampled from several European deciduous forests. An analysis of approx. 9% of the chloroplast genome detected mostly insertion-deletion mutations and one point mutation. In all, 16 haplotypes were detected. Six haplotypes were shared by two or more populations and 10 were unique. One haplotype was present in 21 of the 23 populations and 161 of 211 individuals, which probably indicates its ancient origin. The level of population subdivision, using unordered and ordered alleles, was low, GSTC=0.29 and NSTC=0.33, respectively. The difference between GSTC and NSTC is nonsignificant, indicating an absence of correlation between haplotype phylogeny and geographical distribution. The absence of phylogeographic structure in wild cherry may be attributed to long distance gene flow among populations by birds, animals and anthropogenic activities. The minimum-length spanning tree depicting the phylogenetic relationships between the haplotypes indicates the possible existence of two lineages represented by the haplotypes H3 and H4. The information about homogeneity or heterogeneity of populations in terms of haplotype constitution and detection of rare haplotypes in some populations will be useful for formulation of conservation and management strategies of wild cherry.

Abstract
Research examining the memory-enhancing effects of glucose in humans has been limited to mnemonic tasks lacking affective components, even though glucose may be a mechanism for emotion-induced memory enhancement. This limitation does not permit analysis of interactions between the enhancing properties of emotional stimuli and glucose. Participants were administered either glucose or saccharin 15 min prior to completing a neutral or emotional spatial memory task. Performance under three glycemic conditions (100 mg/kg or 50 g glucose, or placebo) for the two sets of emotional stimuli revealed a significant interaction. Both 100-mg/kg and 50-g doses of glucose resulted in impaired performance for emotional stimuli. For neutral stimuli, a 100-mg/kg dose enhanced memory, whereas a 50-g dose showed no effect. Results indicate that the enhancing effects of emotional stimuli may be attenuated by the consumption of glucose and suggest that recent food consumption should be considered in paradigms examining memory.

Abstract
BACKGROUND AND OBJECTIVES information on the incidence and prevalence of hepatitis E virus (HEV) infection in Indian pregnant women is scanty. Only a few studies have been done so far to document the vertical route of transmission of this virus. We therefore studied the prevalence of HEV infection in pregnant women with hepatitits and the outcome of their pregnancy. METHODS fifty pregnant women with clinical hepatitits were included in the study. After informed consent, their blood samples were tested for potential causes of hepatitis including hepatitis A, B, hepatitis C, and hepatitis E infections. RESULTS of the 50 cases, 20 (40%) patients were found to be positive for IgM anti -HEV (group A) and 30 (60%) were negative for IgM anti-HEV antibodies (group B). Overall 19 patients were in their second trimester while 30 were in third trimester. Of these 52.6 per cen (10/19) of those in second trimester and 50 per cent (15/30) in third trimester had fulminant hepatic failure (FHF). Only one patient presented in the first trimester who had acute viral hepatitis (AVH) and recovered completely. Of the HEV infected women, 70 per cent were in their third trimester and remaining 30 per cent in second trimester of pregnancy. A similar percentage of patients i.e., 14 of 20 (70%) manifested with FHF while 6 (30%) had acute hepatitis leading to recovery. The percentage of women with FHF and acute hepatitis was 36.6 and 63 per cent, respectively, in group B. Upon follow up all the 13 of the 14 HEV infected patients with FHF expired and only one delivered a male baby during the illness. The fatality rate in HEV infected patients was not different between the second and third trimesters (66.6% vs. 71.43%), respectively). INTERPRETATION AND CONCLUSIONS this study suggests that HEV causes high mortality in pregnant women as compared to non-HEV infected pregnant women. This pilot study indicates that steps should be taken to prevent HEV infection during pregnancy.

Abstract
Severe diffuse brain injury in children has a devastating influence on their physical and psychological development. This retrospective study was undertaken to analyse the factors that influence outcome in children with such injuries. The short-term outcomes (Glasgow outcome score) of 74 children (age < or =15 years) with severe diffuse brain injury and no focal operable mass lesions on CT scan, admitted between 1992 and 1998 at the National Institute of Mental Health and Neurosciences were analysed. The prognostic factors analysed were age, gender, time after injury to admission, nature of injury, highest post-resuscitation Glasgow coma score (GCS), pupillary reaction, horizontal oculocephalic reflex and CT scan findings. The following factors were found to be independent predictors of poor outcome: GCS 3-5 (p < 0.003), absent verbal response (p < 0.001), motor response score of 1-3 (p < 0.001), absent pupillary reaction (p < 0.001), absent oculocephalic reflex (p < 0.001) and presence of traumatic subarachnoid haemorrhage on CT scan (p < 0.002). These independent variables were then subjected to a stepwise logistic regression analysis, and the most important variables for predicting outcome were oculocephalic reflex and GCS, which together correctly predicted unfavourable outcome with a sensitivity of 79% and a specificity of 65%. An early CT scan or a single CT scan did not have any prognostic significance.

Abstract
The subunit III of photosystem I and ferredoxin-NADP(+)-oxidoreductase are encoded by nuclear genes, namely psaF and petH. The activity of their promoters from spinach has been evaluated in transgenic tobacco earlier. Evaluation of the activity of these Dicotyledoneae-specific promoters has been carried out in a monocot system (i.e. rice) by transient gene expression system, based on electroporation-mediated gene delivery into protoplasts from leaves and roots. It has been found that various promoter deletions show higher activity in leaf protoplasts and elements for quantitative response are widely distributed. Transgenic rice has also been produced with a petH promoter and gus reporter gene construct. Although petH promoter is a weak promoter in comparison to the 35S promoter, it expresses well in green tissues and could be useful for plant genetic engineering.

Abstract
Although several japonica and some indica varieties of rice have already been transformed, there is significant scope for improvement in the technology for transformation of economically important indica varieties. Successful transformation of rice employing Agrobacterium and recent advances in direct gene transfer by biolistics, evidenced by transfer of multiple genes, have removed some of the serious impediments in the area of gene engineering. The transfer of genes for nutritionally important biosynthetic pathway has provided many opportunities for performing metabolic engineering. Other useful genes for resistance against pests, diseases and abiotic stresses have also been transferred to rice. But the limited knowledge about important target genes requires rapid progress in the field of functional genomics. Transgenic rice system can be applied to isolate new genes, promoters, and enhancers and their functions could be unravelled. The combination of novel regulatory systems for targeted expression and useful new genes should pave the way for improvement of rice and other cereals.

Abstract
The purpose of this study was to consider the effects of valence, motoric direction (i.e., approach/withdrawal), and arousal on the perception of facial emotion in patients with unilateral cortical lesions. We also examined the influence of lesion side, site, and size on emotional perception. Subjects were 30 right-hemisphere-damaged (RHD) and 30 left-hemisphere-damaged (LHD) male patients with focal lesions restricted primarily to the frontal, temporal, or parietal lobe. Patient groups were comparable on demographic and clinical neurological variables. Subjects were tested for their ability to match photographs of four facial emotional expressions: happiness, sadness, fear, and anger. Overall, RHD patients were significantly more impaired than LHD patients in perceiving facial emotion. Lesion side, but not site, was associated with motoric direction and valence dimensions. RHD patients had specific deficits relative to LHD patients in processing negative and withdrawal emotions; there were no group differences for positive/approach emotions. Lesion size was not significantly correlated with accuracy of emotional perception.

Abstract
BACKGROUND Stereotactic biopsies for diagnosing intracranial tuberculomas are often reported to be inconclusive, being confirmatory in only 28% of cases. We analyzed the role and diagnostic efficacy of stereotactic biopsies in the management of intracranial tuberculomas. METHODS Twenty patients diagnosed with intracranial tuberculomas based on neuroimaging procedures underwent computerized tomography (CT) guided stereotactic biopsies for histological confirmation. In 10 patients (Group A), biopsies were obtained from the center of the lesion; in the other 10 (Group B), biopsies were obtained from both the enhancing rim and the isodense center and examined separately. The tissues were processed for paraffin sections and hematoxylin eosin staining. In addition, in the first five patients a squash smear from a small portion of the biopsy was prepared, and the cytological features of the cells were examined. All the patients received antitubercular medication and CT scans were repeated 4 months posttreatment. RESULTS Histopathological features of the paraffin sections in 17 patients (Group A: 8, Group B: 9) were diagnostic of tuberculoma, whereas the other three revealed only chronic nonspecific inflammation. Based on the cytological features in squash smears, diagnosis could be made in one of five. In two, although the smear was not diagnostic, the histological section from the same specimen confirmed the tuberculous pathology. There was no procedural morbidity or mortality. One patient had a small asymptomatic hematoma at the biopsy site. Three patients died during the follow-up period, due to secondary complications of tuberculosis. Repeat CT scans during follow-up after antituberculous treatment confirmed the reduction in the size of the lesion in 15/17 patients. CONCLUSION The high positive yield of stereotactic biopsies in diagnosing tuberculomas argues for their inclusion in the management protocol for tuberculous mass lesions.

Abstract
Two hundred and forty male and 9 female jail inmates confined for various crimes in a district jail near Delhi were screened for sexually transmitted and blood-borne diseases including HIV, syphilis and hepatitis B and C viral infections, skin diseases etc. The inmates were aged 15-50 years with a mean of 24.8+/-0.11. Their alleged criminal background, period of stay in the jail, drug addiction, education, birth place, marital status, sexual activity, and clinical complaints were recorded by an anonymous questionnaire. Serum samples were tested for antibodies against HIV (1+2), hepatitis C (HCV), Treponema pallidum and for hepatitis B surface antigen (HBsAg). Sputum examination was done for acid-fast bacilli. Out of the 240 men, 115 were married and 125 unmarried. One hundred and eighty-four (76.6%) men gave history of penetrative sex. Of the 184, 53 (28.8%) were homosexuals or bisexuals and 131 (71.2%) had sex with women only. Sixty of the 131 (45.8%) were faithful to their partners while 124 gave a history of having multiple sexual partners and 100 of them (80.6%) had unprotected sex. Eighty-three of these 100 also had had sex with commercial sex workers (CSWs). One hundred and twenty-six were addicted for alcohol, 44 for smack/charas and 8 had a history of intravenous drug abuse. One hundred and seventy-four were not aware of AIDS. On examination 28 of the 240 (11.6%) had active hepatitis with or without a history of jaundice in the last 2 years, 25 (10.4%) active pulmonary tuberculosis (TB) and 11 (4.6%) had syphilitic ulcers on the penis. Four-fifths of the teenagers confined to a particular barrack had moderate to severe scabies. Three males (1.3%) were found to be Western blot confirmed HIV-1 positive while 28 (11.1%) men and 2 (22.2%) women were positive for HBsAg. Twelve (5.0%) men but no women, were found to be positive for anti-HCV antibodies. Out of the 3 HIV-positive persons, one was an intravenous drug user (IVDU), second was a drug addict and frequent CSW visitor while the third was a homosexual. This pilot study gives an indication that sexually transmitted and blood-borne infections are highly prevalent in jail premises and pose a threat of rapid spread of these infections through IVDU and homosexuality.
