Abstract
This prospective cross-sectional study evaluated the diagnostic and prognostic role of cerebrospinal fluid (CSF) tumor necrosis factor-alpha (TNF-α) in children with cerebral malaria (CM) and its role in the differentiation of CM from non-cerebral severe malaria. CSF TNF-α was measured using a human TNF-α enzyme-linked immunosorbent assay kit of 39 cases of CM and 19 cases of non-cerebral severe malaria. CSF TNF-α levels were significantly higher in CM (p < 0.001). Based on the receiver operating characteristics curve, a cutoff value of CSF TNF-α was 5.7 pg/ml for diagnosis of CM with sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 87.2%, 94.7%, 97.1% and 78.3% respectively. The cutoff value of CSF TNF-α was 13.7 pg/ml for predicting adverse outcomes in CM with sensitivity, specificity, PPV and NPV of 100%, 96.8%, 88.9% and 100%, respectively. However, the cutoff value of CSF TNF-α was 4.96 pg/ml for predicting adverse outcomes in non-cerebral severe malaria with a sensitivity, specificity, PPV and NPV of 100%, 94.1%, 88.9% and 100% respectively. So, CSF TNF-α is an excellent biomarker and can be used as a diagnostic and prognostic tool. More studies are needed to establish CSF TNF-α as a predictor of neurological sequelae.

Abstract
PURPOSE/OBJECTIVE(S) To evaluate the efficacy of P - PART with concurrent chemotherapy in LACC with the use of intensity modulated radiotherapy technique (IMRT). Our Primary endpoint was to assess acute toxicities and secondary endpoint was to assess loco-regional control (LRC), disease free-survival (DFS), para-aortic recurrence free survival (PA-RFS). MATERIALS/METHODS A total of 30 patients of squamous cell carcinoma of cervix with stage IIIC1 (FIGO-2018) were recruited in this prospective, single arm interventional phase II study between January 2021 to September 2022. 18FDG-PET CT was performed and those with positive PALN were excluded. IMRT was used to deliver a dose of 50 Gy in 25 fractions to whole pelvis and PALN chain below renal hilum till aortic bifurcation received 45 Gy in 25 fractions. Concurrent cisplatin was administered weekly at 40 mg/m2 during radiation. On completion of external beam radiotherapy, high dose rate intracavitary brachytherapy was given at 7 Gy per fraction in 3 fractions prescribed to HR-CTV. Acute toxicities were assessed using CTCAE version 5.0. RESULTS Median age was 50 years (37-66 years). All patients had completed treatment as per protocol. All patients had positive pelvic nodes with the maximum nodal short axis dimension of 14 mm (10-18 mm). All patients had positive internal iliac group of LNs, only 2(6.6%) patients had positive common iliac group of Ln. Median number of concurrent cisplatin cycles given were 5 (3-5 cycle). Median overall treatment time was 56 days (52-63 days) and median follow up was 15 months (3-22 month). Median cumulative dose to HR-CTV was 84.3Gy (Range:79.2-86.9Gy). Cumulative median EQD2 to 2cc of bladder and rectum were 69.11Gy (Range:59.17 - 80.07 Gy) and 64.6 Gy (Range: 60.1-66.3Gy) respectively. 7(23.3%) patients having grade 3 diarrhea and 2(6.67%) patients had grade 3 anemia while no significant genitourinary or other toxicities were noted. Patient characteristics, dosimetric data are described in Table-1. All patients underwent clinical and radiological assessment at the time of last follow up with one (3.33%) patient experiencing local failure at 9 months of follow up, hence crude LRC rate is 96.6%, DFS is 13.5 months (5-22 months) and PA-RFS is 16 months (8-23 months) till last date of follow up. CONCLUSION Prophylactic EFRT with concurrent chemotherapy using IMRT technique yielded excellent short term clinical outcomes with acceptable toxicity profiles. Longer follow up will elucidate late toxicity and long-term clinical outcomes.

Abstract
PURPOSE/OBJECTIVE(S) Oral cavity squamous cell carcinoma (OCSCC) is the most common head and neck cancer in India. Definitive surgery with or without post-op radiotherapy (PORT) with or without chemotherapy (CT) provides better outcomes in locally advanced OCSCC as compared to definitive chemoradiotherapy. T4b OCSCC with infra temporal fossa (ITF) involvement has varied outcome depending on the extent of ITF involvement, with low and mid ITF having relatively favorable prognosis. We aimed to prospectively evaluate outcomes in patients of OCSCC with low or mid ITF involvement treated with curative surgery followed by adjuvant concurrent chemoradiotherapy (CCRT). MATERIALS/METHODS A total of 20 patients of T4b OCSCC (as per AJCC 8th edition) with low or mid ITF involvement were included in this single arm prospective interventional study from January 2021 to October 2022. Patients with involvement of skull base, carotid artery, prevertebral fascia and/or pterygomaxillary fissure were excluded. All patients were treated with definitive surgery with ITF clearance followed by adjuvant CCRT as indicated. Loco-regional control (LRC), Disease free survival (DFS), Overall survival (OS) were assessed using Kaplan-Meier survival analysis. Acute toxicities were assessed according to the CTCAE v5.0. RESULTS Patient characteristics are summarized in table 1. Median follow-up was 11.5 months (4-21months). All patients received adjuvant CCRT with weekly cisplatin 40mg/m2 to a median number of 6 cycles (5-7 cycles). Median RT dose was 64Gy (60-64Gy). All patients tolerated treatment well. Grade 3 oral mucositis, odynophagia were seen in 8 (40%) patients each and skin toxicity, oral pain in 6 (30%) and 5 (25%) patients respectively. No grade 4 toxicities were observed LRC at three month was 73.68% with 4 local and 1 locoregional failure only. LRC at one year was 36.8% with 8 local, 1 locoregional, 2 locodistant and 1 distant failure only. Median DFS was 10.4 months. Median OS was not reached; four patients died. LRC at three months was better for patients with low ITF disease as compared to mid ITF disease (85.7% vs. 40% (p = 0.04) and at one year was 42.8% vs. 40% (p = 0.50). CONCLUSION Selected patient of locally advanced OCSCC with low ITF involvement may benefit from trimodality therapy of surgery with ITF clearance followed by adjuvant CCRT. Acute toxicity profile was acceptable in our study.

Abstract
Diabetic foot ulcer (DFU) is globally a major health burden predisposing to limb amputation. Among the various treatment modalities, platelet-rich plasma (PRP) is emerging as a promising agent. It stimulates wound healing by providing a higher concentration of essential growth factors locally. Though the role of PRP in DFU healing is established, still the route of administration with maximal efficacy is yet to be defined. Our study aims to evaluate the efficacy of autologous PRP in the treatment of diabetic ulcers and compare the effect of topical and perilesional injections of PRP in DFU healing. We conducted a single-centre, prospective, interventional study on 60 patients with DFU, in 2 groups of 30 patients each. They were treated with freshly prepared autologous PRP injection perilesionally and topically respectively, once a week for 4 weeks. Ulcer size was assessed, using "imito-measure" software at presentation and 2, 4, 8, and 12 weeks post-therapy. Serum MMP-9 levels were assessed in both groups, pretreatment and post-treatment. For statistical analysis, SPSS software V-23 was used. On assessment, both groups had comparable baseline characteristics, Wagner's grading, and glycemic indices. The percentage reduction in the size of the wound at 2 weeks, 1 month, 2 months, and 3 months was greater in the perilesional group as compared to the topical PRP group.

Abstract
Crop yield varies considerably within agroecology depending on the genetic potential of crop cultivars and various edaphic and climatic variables. Understanding site-specific changes in crop yield and genotype × environment interaction are crucial and needs exceptional consideration in strategic breeding programs. Further, genotypic response to diverse agro-ecologies offers identification of strategic locations for evaluating traits of interest to strengthen and accelerate the national variety release program. In this study, multi-location field trial data have been used to investigate the impact of environmental conditions on crop phenological dynamics and their influence on the yield of mungbean in different agroecological regions of the Indian subcontinent. The present attempt is also intended to identify the strategic location(s) favoring higher yield and distinctiveness within mungbean genotypes. In the field trial, a total of 34 different mungbean genotypes were grown in 39 locations covering the north hill zone (n = 4), northeastern plain zone (n = 6), northwestern plain zone (n = 7), central zone (n = 11) and south zone (n = 11). The results revealed that the effect of the environment was prominent on both the phenological dynamics and productivity of the mungbean. Noticeable variations (expressed as coefficient of variation) were observed for the parameters of days to 50% flowering (13%), days to maturity (12%), reproductive period (21%), grain yield (33%), and 1000-grain weight (14%) across the environments. The genotype, environment, and genotype × environment accounted for 3.0, 54.2, and 29.7% of the total variation in mungbean yield, respectively (p < 0.001), suggesting an oversized significance of site-specific responses of the genotypes. Results demonstrated that a lower ambient temperature extended both flowering time and the crop period. Linear mixed model results revealed that the changes in phenological events (days to 50 % flowering, days to maturity, and reproductive period) with response to contrasting environments had no direct influence on crop yields (p > 0.05) for all the genotypes except PM 14-11. Results revealed that the south zone environment initiated early flowering and an extended reproductive period, thus sustaining yield with good seed size. While in low rainfall areas viz., Sriganganagar, New Delhi, Durgapura, and Sagar, the yield was comparatively low irrespective of genotypes. Correlation results and PCA indicated that rainfall during the crop season and relative humidity significantly and positively influenced grain yield. Hence, the present study suggests that the yield potential of mungbean is independent of crop phenological dynamics; rather, climatic variables like rainfall and relative humidity have considerable influence on yield. Further, HA-GGE biplot analysis identified Sagar, New Delhi, Sriganganagar, Durgapura, Warangal, Srinagar, Kanpur, and Mohanpur as the ideal testing environments, which demonstrated high efficiency in the selection of new genotypes with wider adaptability.

Abstract
Background Pancreatic exocrine insufficiency (PEI) is a well-defined complication of malignant diseases and pancreatic resection; however, study results of PEI are less consistent. Assessment of PEI by estimation of fecal elastase (FE)-1 in stool by enzyme-linked immunosorbent essay (ELISA) is a relatively inexpensive, noninvasive, and simple test. This study assessed exocrine function of pancreas following pancreaticoduodenectomy (PD) by estimating FE-1. Methods This prospective hospital-based study involved 30 patients who had undergone PD for malignancy. All 30 patients had an uneventful postoperative period under the unit's enhanced recovery after surgery (ERAS) protocol with no Grade B, C postoperative pancreatic fistula/postpancreatectomy hemorrhage as per the International Study Group of Pancreatic Surgery (ISGPS) definitions. Stool samples were collected postoperatively 3 months after surgery from all patients irrespective of clinical symptoms. The analysis was based on a solid phase ELISA used for the quantitative determination of human elastase 1 in feces. Fecal elastase was considered normal if >200 μg/gm stool, moderately reduced if 100-200 μg/gm stool, and severely reduced if <100 μg/gm stool. Results Among 30 patients included, fecal elastase levels were moderately reduced in 10 (33.33%) and severely reduced in 20 (66.67%) patients (P <0.0001). Mean (± standard deviation) of fecal elastase was 87.12 ± 38.76 with median of 74.6 μg/gm stool. There was no significant difference in the fecal elastase levels between men and women (P = 0.057), age (P = 0.48), pancreatic duct diameter (P = 0.609), pancreatic texture (P = 0.286), and presence or absence of clinical symptoms (P = 0.181). Conclusions PD was frequently associated with PEI. Unfortunately PEI is an under recognized and under treated long-term sequel of PD. Fecal elastase 1 should be performed routinely in both symptomatic and asymptomatic patients. Pancreatic enzyme replacement therapy should be considered in every patient after PD.

Abstract
Background: Brachytherapy treatment planning in cervix carcinoma patients using two dimensional (2D) orthogonal images provides only point dose estimates while CT-based planning provides volumetric dose assessment helping in understanding the correlation between morbidity and the dose to organs at risk (OARs) and treatment volume.
Objective: Aim of present study is to compare International Commission on Radiation Units and Measurements Report 38 (ICRU 38) reference point doses to OARs with volumetric doses using 2D images and CT images in patients with cervical cancer.
Material and Methods: In this prospective study, 20 patients with cervical cancer stages (IIB-IIIB) were planned for a brachytherapy dose of 7Gy per fraction for three
fractions using 2D image-based treatment plan and CT-based plan. ICRU 38 points for bladder and rectum were identified on both 2D image-based plan
and CT-based plan and doses (DICRU) at these points were compared to the minimum dose to 2cc volume (D2cc) of bladder and rectum receiving the highest dose.
Results: D2cc bladder dose was 1.60 (±0.67) times more than DICRUb bladder dose whereas D2cc rectum dose was 1.13±0.40 times DICRUr. Significant difference
was found between DICRUb and D2cc dose for bladder (p=.0.016) while no significant difference was seen between DICRUr and D2cc dose for rectum (p=0.964).
Conclusion: The study suggests that ICRU 38 point doses are not the true representation of maximum doses to OARs. CT-based treatment planning is more a reliable tool for OAR dose assessment than the conventional 2D radiograph-based plan.

Abstract
Pancreatic exocrine insufficiency (PEI) is a common long-term complication after pancreaticoduodenectomy (PD) and is observed in 23-80% of patients. As the postoperative mortality after PD has substantially decreased, it warrants more attention on the diagnosis and treatment of functional long-term consequences after PD. These include PEI and endocrine insufficiency that can result in significant nutritional impairment and often adversely impacts quality of life (QOL) of the patient. A PubMed search was performed for articles using key words "pancreatic exocrine insufficiency"; "pancreaticoduodenectomy"; "quality of life after pancreaticoduodenectomy"; "stool elastase"; "direct, indirect tests for pancreatic exocrine insufficiency"; "pancreatic enzyme replacement therapy." Relevant studies were shortlisted and analyzed. This review summarizes relevant studies addressing PEI following PD. We also discuss functional changes after PD, risk factors and predictive factors for postoperative PEI, clinical symptoms, direct and indirect tests for estimation of PEI, pancreatic enzyme replacement therapy (PERT), and QOL after pancreatic resection for malignancy. It was found that significant PEI occurs in most patients following PD. Fecal elastase 1 is an easy indirect test and should be performed routinely in both symptomatic and asymptomatic patients after PD. PERT should be considered in every patient after PD with the aim to improve the QOL and perhaps even their long time survival.

Abstract
INTRODUCTION Breast cancer represents a major public health problem in women worldwide. For many cancers, serum tumour markers play an important role in patient treatment and monitoring. Isocitrate dehydrogenase enzyme is also used as a biomarker for various types of cancer. AIM The purpose of this study was to determine serum Isocitrate dehydrogenase-2 (IDH-2) enzyme activity in breast cancer patients (pre and post chemotherapy) and also correlate the changes in enzyme activity with stages of cancer and control groups. MATERIALS AND METHODS In this case-control study, histologically confirmed 40 female patients aged 28-80 years who fulfilled the criteria for diagnosis of invasive breast cancer were selected in our study groups from surgery outpatient department of SS Hospital, BHU, Varanasi, India, and 40 healthy age matched females were selected between October 2013 to July 2015. The estimation of serum IDH-2 enzyme activity in before and after two cycles of neoadjuvant chemotherapy patients was performed by spectrophotometry assay. RESULTS The mean serum IDH-2 activity in cases (Mean±SD) was significantly more than control group (p<0.001). The mean serum IDH-2 activity in cases was significantly decrease after neo-adjuvant chemotherapy (p=0.019). In stage II pre chemotherapy patients serum IDH-2 activity was higher than post chemotherapy (p<0.05), but in stage III the correlation between pre and post chemotherapy patients serum IDH-2 activity was not significant (p-value>0.05). CONCLUSION The serum IDH-2 can be a potential biomarker in breast carcinoma and can be used for prognosis and monitoring the chemotherapy response of the patients.

Abstract
In vitro dosimetric verification prior to patient treatment has a key role in accurate and precision radiotherapy treatment delivery. Most of commercially available dosimetric phantoms have almost homogeneous density throughout their volume, while real interior of patient body has variable and varying densities inside. In this study an attempt has been made to verify the physical dosimetry in actual human body scenario by using goat head as "head phantom" and goat meat as "tissue phantom". The mean percentage variation between planned and measured doses was found to be 2.48 (standard deviation (SD): 0.74), 2.36 (SD: 0.77), 3.62 (SD: 1.05), and 3.31 (SD: 0.78) for three-dimensional conformal radiotherapy (3DCRT) (head phantom), intensity modulated radiotherapy (IMRT; head phantom), 3DCRT (tissue phantom), and IMRT (tissue phantom), respectively. Although percentage variations in case of head phantom were within tolerance limit (< ± 3%), but still it is higher than the results obtained by using commercially available phantoms. And the percentage variations in most of cases of tissue phantom were out of tolerance limit. On the basis of these preliminary results it is logical and rational to develop radiation dosimetry methods based on real human body and also to develop an artificial phantom which should truly represent the interior of human body.

Abstract
Fifty cases of severe malaria were studied for their oxidant and antioxidant status. Severe anemia (54%) was the most common presentation followed by hyperpyrexia, cerebral malaria and jaundice. Plasma malondialdehyde, protein carbonyl, nitrite, ascorbic acid and copper levels were significantly raised in cases as compared with controls (p < 0.001). Plasma ceruloplasmin, glutathione and superoxide dismutase levels were significantly decreased in children with severe malaria (p < 0.001). Plasma zinc was increased in cases but difference is not statistically significant. Significantly decreased level of nitrites and increased value of glutathione was found in patients with hemoglobinuria and jaundice, respectively. The significantly elevated malondialdehyde and protein carbonyl levels reflect the increased oxidative stress, whereas decreased levels of glutathione and superoxide dismutase point toward utilization of the antioxidants in severe malaria. Thus, changes in oxidants and antioxidants observed suggest the production of reactive oxygen species and their possible role in pathogenesis of severe malaria.

Abstract
The EPR studies have been carried out on gamma irradiated samples of Pd(ClO4)2 in 9 M/4M HClO4 in the presence and absence of isopropanol [i-PrOH (5%, v/v)], in the temperature range of 77-300 K. The EPR studies revealed the formation of Pd+ complex, Pd3+ complex and several radicals such as H., OH., ClO3., ClO4. and O3- on radiolysis of these systems. Reduction of Pd2+ to Pd clusters could not be observed in the absence of i-PrOH and warming of the irradiated sample finally resulted in recovery of Pd2+ complex. However, in the presence of 5% i-PrOH, strongly oxidizing radicals like OH., ClO3. and ClO4. are suppressed and (CH3)2C.OH radical was produced along with reducing species like H.. EPR spectra in these strongly reducing conditions showed formation of Pd+ complex, which on heating above 230 K, disproportionated into Pd0 and Pd2+ complex and finally lead to formation of Pd metal aggregates. Simultaneously, pulse radiolysis technique has been employed as an alternative method to verify the EPR observations.

Abstract
The removal of fluoride from aqueous solutions has been investigated using various oxide ores such as refractory grade bauxite, feed bauxite, manganese ore, and hydrated oxides of manganese ores (WAD). The refractory grade bauxite showed promising results. The studies were carried out as functions of contact time, pH, concentration of adsorbents, concentration of adsorbate, and temperature. The adsorption was rapid during the initial 5 min but equilibrium was attained within 120 min. The adsorption followed first-order kinetics. The present system followed the Langmuir adsorption isotherm model. Various thermodynamic parameters such as free energy, enthalpy, entropy, and equilibrium constants were calculated. The isosteric heat calculations showed that the adsorption process followed a heterogeneous model.

Abstract
The uptake of Ba(II) and Sr(II) by hydrous ferric oxide (HFO) was studied as a function of contact time, concentration, temperature and pH of the respective adsorptive solutions employing the 'radiotracer technique'. The uptake of both the ions was found to increase with the increase in concentration, temperature and pH of the adsorptive solutions. Concentration dependence data fitted well to the Freundlich adsorption isotherm over the entire range of concentration (10(-2)-10(-7) M) and the uptake process followed first-order rate kinetics. The desorption experiments demonstrate the irreversible nature of the uptake process, however, in the presence of H+ ions, i.e. on acidification, an appreciable amount of metal ions were removed in the bulk solution. The radiation stability of hydrous ferric oxide towards the uptake of Ba(II) and Sr(II) was also examined by using samples of hydrous ferric oxide irradiated by neutrons and gamma-rays prior to be employing as sorbents. The presence of some mono- and divalent co-ions along with the studied ions suppressed their removal appreciably.

Abstract
Sequestering of Zn(II) ions at the surface of rice husk has been studied as a function of contact time, adsorptive concentration, temperature and pH, using the radiotracer technique employing a 65Zn radiotracer. A relatively slow uptake of metal ion increasing with bulk dilution (10(-2) to 10(-7) mol/dm3) was seen, which obeys the first-order rate law and agrees well with the classical Freundlich adsorption isotherm. The removal of metal ions from the bulk increases with the increase in pH (3.2-10.2) and temperature (293-323K) and evaluation of the thermodynamic data shows that the process involved is endothermic and apparently irreversible in nature, suggesting an ion exchange mechanism along with surface complexation. On the other hand Cd(II) was not adsorbed on the surface of the rice husk at pH 6.2.

Abstract
OBJECTIVE A clinicopathological study of patients presenting with necrotizing enteritis, similar to the Pig-Bel disease of Papua New Guinea. METHODS A clinicopathological study of 95 patients presenting in last ten years with acute abdominal pain with diarrhea and/or bleeding per rectum and vomiting and found to have lesions similar to Pig-Bel disease. RESULTS 89% of the patients were young adult vegetarians from lower socio-economic strata. 94% of cases presented between May and August every year showing a marked seasonal variation. Jejunum was the most common site (95%) involved. Gross examination showed blackish brown 'skip' lesions with gangrene and perforations. Histology showed marked necrosis and congestion of all the layers with mucosal ulcerations. CONCLUSION A disease simulating Pig-Bel disease occurs in India. It is more common in young adult vegetarians and may have a different etiology from that proposed in endemic regions.

Abstract
Forty-seven patients with esophageal variceal bleeding were randomly allocated to undergo sclerotherapy on a 3 weekly schedule with either 5% ethanolamine oleate (23 patients) or absolute alcohol (24 patients), in an attempt to compare the efficacy and safety of the two sclerosants. Sclerotherapy with absolute alcohol eradicated esophageal varices significantly earlier compared with ethanolamine oleate (12.9 +/- 5.2 vs 22.3 +/- 8.2 wk, respectively, p less than 0.001). The mean number of injection courses and the mean amount of sclerosant required for variceal obliteration was also significantly (p less than 0.001) less in the alcohol-injected group. Although the total number of rebleeding episodes were significantly (p less than 0.05) less in the alcohol-injected group, the frequency of rebleeding was not significantly different between the two groups (20.8% vs 30.4%, respectively, p greater than 0.05). Two (8.1%) patients died due to rebleeding in the ethanolamine-injected group, whereas in the alcohol group, none died. There was no significant difference in the frequency of complications with the two sclerosants. Besides the relative ease of rapid injection due to its aqueous nature, alcohol is readily available and relatively economical (total cost of sclerosant per patient; alcohol US $0.50, ethanolamine US $60). In conclusion, absolute alcohol appears to be a useful alternative to 5% ethanolamine oleate as a variceal sclerosant.

Abstract
The construct validity of the Reitan-Indiana Neuropsychological Test Battery (R-INB)for Children with a learning disabled population was examined. Forty-two subjects classified as learning disabled also were administered the Wechsler Intelligence Scale for Children-Revised (WISC-R) and Wide Range Achievement Test (WRAT) subtests. Factor analysis of the data revealed four factors: verbal intelligence, psychomotor speed, achievement, and memory. Evidence from this study indicates that the overall construct paradigm as conceptualized by the author of the R-INB does not exist. Implications of these findings are discussed.

Abstract
There are few studies available comparing the efficacy of loop and distal diuretics and a combination of the two groups, in the treatment of ascites due to liver disease. Thirty-seven nonazotemic cirrhotic patients with ascites were randomly allocated to receive for 2 weeks bumetanide (group A, n = 13), spironolactone (group B, n = 12) or a combination of the two drugs (group C, n = 12) after a 5-day stabilization period. The response to the treatment was 69, 42 and 83% in groups A, B and C, respectively; the difference was not significant. Hypokalemia was seen in 4 patients of group A and mild hyperkalemia in 2 patients of group B. Electrolyte disturbances were minimal in patients of group C. The response to diuretic treatment was prompt in groups A and C. It can be concluded that a combination of loop and distal diuretics is superior to a one-drug regimen in achieving a rapid and better diuretic response with fewer side effects.

Abstract
Examined the generalizability of the Bannatyne WISC-R profile of learning-disabled children to a sample of children from Mexican-American culture. A sample of 64 Mexican-Americans diagnosed as learning disabled were used in the study. Recategorized scores were subjected to 1 X 3 repeated measures ANOVAs and the differences between mean categorized scores were analyzed by Newman-Keuls tests for simple effects. Analysis of the obtained data suggested that learning-disabled Mexican-American children were not characterized by Spatial greater than Conceptual greater than Sequential patterns as predicted by Bannatyne. The WISC-R performance of these children was found to be similar on Sequential and Conceptual categories. In spite of the lack of generalizability of the Bannatyne profile to the Mexican-American group, some interesting similarities and differences in performance patterns of the two groups of Ss were observed.

Examined the WISC-R profiles of learning-disabled children from the Papago culture. A sample of 46 Papagos diagnosed as learning disabled were used in the study. Recategorized scores were subjected to 1 X 3 repeated measures ANOVA, and the differences between mean categorized scores were analyzed by Newman-Keuls tests for simple effects. Analysis of the obtained data suggested that learning-disabled Papago children were not characterized by Spatial greater than Conceptual greater than Sequential pattern because WISC-R performance of these children was found to be similar on Sequential and Spatial categories. Caution in the use of WISC-R profile for differential diagnosis was recommended.

Abstract
Examined the comparability of the WAIS and WAIS-R by administering the two scales to a sample of 88 adults in a counterbalanced order. The obtained data were analyzed by correlational and repeated measure three-way analysis of variance procedure. The indices of obtained correlation coefficients suggested a high degree of similarity between the two scales. The findings from ANOVA indicated statistically significant differences in the subtest performance (except in the performance of the Picture Arrangement), and three IQs on the WAIS and WAIS-R. Performance of Ss was found to be higher on the WAIS as compared to their performance on corresponding subtests and IQs on the WAIS-R. These results were found to be consistent with the data reported by earlier studies that compared revisions of the Wechsler and Stanford-Binet scales with older tests.

Abstract
Compared the scores obtained by high and low anxious Ss, when the Wechsler Adult Intelligence Scale was administered by a trained examiner, with those obtained when the test was administered mechanically. A sample of 40 Ss were classified into high and low anxious groups in terms of their scores on the Taylor Manifest Anxiety Scale. Each S was given half the items of the WAIS verbal scale by a trained examiner and half by machine. Analysis of the scores under these two modes of test presentation, using a 2 X 2 X 2 factional analysis of variance, showed no significant differences in performance of high and low anxious Ss under two testing situations. Similarly, there were no differences in the performance of male and female Ss. However, the Ss showed a significant tendency to score higher when the test was given by an examiner than when the test was administered mechanically. Such differences, however, were not observed when the scores on each subtest were compared under two testing conditions except in the case of the Information and Arithmetic subtests.
