Abstract
Abstract
Aim
To compare the safety and efficacy of monopolar vs bipolar TURBT.
Method
This was a randomized control trial done over 18 months with patients being allotted randomly into the bipolar and monopolar arms. The study was carried out in the department of urology at BRI and YC. All consecutive patients undergoing TURBT for suspected bladder tumors were eligible for the study. The diagnosis was based on imaging and/or cystoscopy. Exclusion criteria included refusal to participate, unfitness for spinal anesthesia, and lack of tumor in the lateral wall. The primary objective was to compare the incidence of obturator jerk in monopolar and bipolar TURBT. The secondary objective was to study and compare the quality of histopathology specimen, detrusor muscle identification, and bladder perforation.
Results
A total of 95 transurethral resections were done over the study period. All these patients were eligible for inclusion in the study, 50 in monopolar and 45 in the bipolar arms, were analyzed. Both the study groups were comparable for age, sex, and tumor size. The incidence of obturator jerk was greater in the bipolar arm (8.8 %% vs 2%, P- value=2.25). The difference in the incidence of obturator jerk in the two arms was not statistically significant (Chi-Square test). There was no significant difference in either of the secondary outcomes.
Conclusions
The bipolar transurethral resection of the bladder tumor was not superior to monopolar resection concerning the obturator jerk, bladder perforation, and histopathological quality of the resected specimen.

Exogenous application of bio-stimulant and growth retardant improved the productivity of cotton cultivars under different planting arrangement. BRAZ J BIOL 2021; 82:e238812. [PMID: 34161424 DOI: 10.1590/1519-6984.238812] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2020] [Accepted: 12/11/2020] [Indexed: 11/22/2022] Open
Abstract
Optimum planting arrangement is an important attribute for efficient utilization of available resources and to obtain high yield of cotton. Application of plant growth promoter and retardant on cotton in improved planting density are the innovative techniques in the establishment of more productive cotton crop. Therefore, we planned a field study to assess the role of bio-stimulant and growth retardant in the resource utilization efficiency of cotton cultivars planted under variable row spacing at Agronomic Research Area Bahauddin Zakariya University and Usmania Agricultural Farm Shujabad during Kharif 2012. Experimental treatments consisted of cotton genotypes viz. CIM-573 and CIM-598, cultivated under conventional (75 cm), medium (50 cm) and ultra-narrow row spacing (25 cm) with foliar spray of bio-stimulant (moringa leaf extract) and growth retardant (mepiquate chloride), either sole or in combination, keeping distilled water as a control. Exogenously applied MLE alone and MLE + MC significantly enhanced the number of squares, flowers and green bolls per plant leading to higher cotton seed and lint yield of CIM 598 cultivar cultivated under conventional row spacing. While application of MC alone and MLE + MC produced maximum micronaire value, fiber strength and fiber uniformity ratio of CIM 573 cultivar cultivated under conventional row spacing. The results suggested that application of MLE is a possible approach to enhance the cotton productivity and the use of MC to enhance the fiber quality attributes under conventional row spacing.

Abstract
Plant growth regulators and improved planting density are the innovative techniques in the establishment of more productive cotton crop. A field study was planned to assess the role of growth regulators in the resource utilization efficiency of cotton cultivars under different row spacing at Agronomic Research Area, Bahauddin Zakariya University Multan and Usmania Agricultural Farm, Shujaabad during Kharif 2012. The study was comprised of cotton cultivars viz. CIM-573 and CIM-598, cultivated under conventional (75 cm), medium (50 cm) and improved ultra-narrow row spacing (25 cm) and foliar spray of growth regulators viz. moringa leaf extract (MLE) and mepiquat chloride (MC), either alone or in combination, distilled water as a control. The application of MLE alone and in combination (MLE + MC) showed the promoting effect on crop growth rate, net assimilation rate, leaf area index, leaf area duration, sympodial branches and number of bolls leading to higher seed cotton yield of both cotton cultivars grown under conventional row spacing. While application of MC averts the plant growth without considerably improving the productivity. MLE being rich source of growth promoting hormone and nutrients showed its potential to a far greater extent under conventional row spacing in efficient utilization of available resources compared to MC and distilled water.

Abstract
Complementary feeding is a transition of the baby's intake over 6 months to meet the
nutritional needs in addition to breast milk. Complementary feeding should contain
complete nutritional components especially in minerals. Minerals are elements needed by
the body for the overall body function. Children require calcium (Ca), iron (Fe), and zinc
(Zn) for their body growth to prevent stunting. This study was aimed to analyse Ca, Fe
and Zn content in the formulated fish protein hydrolysate (FPH) complementary feeding
porridge. A total of three formulations were produced namely F1, F2 and F3 and analysed
for mineral content following AOAC method 999.11. From the analysis, F3 had the
highest Fe content (38.547 mg/100 g) and Zn content (5.751 mg/100 g) while F1 had the
highest Ca content (65.152 mg/100 g). Overall, F3 had the best mineral content to be
formulated as a suitable FPH complementary feeding instant powder.

Anomalous aortic origin of a coronary artery (AAOCA): A case report. THE MEDICAL JOURNAL OF MALAYSIA 2019; 74:436-438. [PMID: 31649223] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/10/2023]
Abstract
Anomalous Aortic Origin of a Coronary Artery (AAOCA) is a rare anomaly of the coronary artery with a considerable risk of sudden cardiac death due to ischaemia of the heart. Symptoms may include chest pain on exertion, breathlessness or dizziness. We encountered a case of a 46- year-old female who complained of exertional chest pain with a positive-stress test and subsequently diagnosed with AAOCA through CT angiography (CTA). She successfully underwent a coronary artery bypass graft (CABG) surgery using a saphenous vein graft with uneventful recovery. Right internal mammary artery (RIMA) was not used as it was flimsy and the flow was very poor.

Abstract
Folic acid (FA) is an electroactive compound of biological origin. It helps our body to produce and maintain healthy cells. It can significantly reduce the occurrence of neural tube defects and also prevents change in DNA structure. FA deficiency can lead to various health risks. Therefore, a sensitive, specific, and reproducible way of FA detection is essential. A number of analytical methods are in practice for the quantification of FA. However, electroanalytical methods are attracting much attention because of their advantage over conventional methods, as they are fast, simple, sensitive, and cost effective. Moreover, modification of electrodes offers control over size and morphology which allows miniaturization for applicability in portable electrochemical devices.

Abstract
Leucine-rich repeats and immunoglobulin-like domains (LRIG)-1 belong to the family of proteins known to be expressed in skin. Ablation of LRIG1 in mice results in epidermal hyperplasia and its aberrant expression levels have been reported in pathological conditions such as psoriasis, thus evident of an indispensible role of LRIG1 in maintaining epidermal homeostasis. In order to gain insight into the homeostatic expression of LRIG1 and in various stages of cutaneous wound healing, LRIG1 expression was immunohistochemically analyzed in full thickness skin wounds in mice. The full thickness skin wounds were established on the dorsal back of Balb/c mice (n=6). LRIG1 expression at various post wounding days (1, 2, 3, 6 and 14) was determined through Immunohistochemical analysis (IHC) of the murine skin sections. The injury caused a sharp decline in LRIG1 expression in the basal epidermal cells and appendages surrounding the wound which correlates with the re-epithelialization phase of healing. LRIG1 expression remained down regulated during most of the wound healing stages. LRIG1+ cells were found to re-populate the neo-epidermis on day 14, suggesting an important homeostatic role of LRIG1 in skin.

Abstract
BACKGROUND Placenta accreta is a condition of abnormal placental attachment that was usually treated by hysterectomy. Techniques to conserve the uterus are now commonly used and series of subsequent pregnancy outcomes have been reported. The recurrence risk of placenta accreta is now a relevant detail and is currently not known. This work was performed to calculate the recurrence risk by reviewing the published literature. METHODS A literature search using the terms "placenta accreta", "placenta percreta", "placenta increta", "abnormal placental attachment" and "placental attachment disorder" followed by hand-searching identified 6 papers that contained data concerning recurrence of placenta accreta in subsequent pregnancies following initial conservative treatment. RESULTS Overall 407 pregnancies were recorded and 85.7% of women reported achieved a subsequent pregnancy following conservative treatment. The risk of recurrence of placental attachment disorder in a subsequent pregnancy was 19.9% (weighted mean, 95% CI 12.2-27.7). CONCLUSIONS The recurrence risk of placental attachment disorder following uterine conservation treatments is 20% . This risk should be discussed with women with an antenatal diagnosis of a placental attachment disorder who may be considering uterine conservation in order to retain the option of a future pregnancy.

Abstract
Note: a new paragraph 'What this study adds:' was added to page 250 on 27 March 2014.Background Social networking sites are web-based services through which individuals can create a public or semi-public profile within a bounded system, connect with a list of other linked users, and view and interact with a list of their connections and with those made by others within the system. To estimate the proportion of university students using social networking sites (SNS) and to determine the association between SNS use and age, gender, nationality, course and year of study, living context, family size, number of close friends, close relationships, stress related to studies and interpersonal relationships. Materials and Methods A cross sectional study was carried out among 300 students from two universities in Ajman, UAE. A self-administered, content-validated and pilot-tested questionnaire was used. The participants answered questions related to their use of social networking sites and details of socio-demographic variables. The data collected were entered into Microsoft Excel and transferred to PASW 18.0 version. Data were analyzed as frequencies, percentages, means and SDs, and Chi-square test used for associations. The odd ratio was calculated for the significant variables to find the degree of association. The SNS usage was categorized as average, moderate or high based on mean and SD on the SNS test score. Results The study population was comprised of 41.6% males and 58.3% females. 89% used social networking sites (SNS) and 11% were non-users. Of the 267 users of SNS, 58.8% were average users, 37.8% moderate users and 3.4% high users. Students in the first and second years of study, small family size, age below 20 years, male gender, being in a non-medical study program, friends in close relationship were found to be associated with higher SNS use. Conclusion Social networking sites were found to be popular among a large number of university students in the UAE, this being more so among males and non-medical students of first two years of study.

Abstract
AIMS To describe contraception use and the prescription of drugs that are either not recommended in pregnancy or are potentially teratogenic by diabetes type in women of child-bearing age. METHODS Retrospective, cross-sectional chart review undertaken in 22 general practices in Warwickshire, UK. Demographic, anthropometric, medical history, medication and contraception data were extracted from women aged 14 to 49 years with pre-existing diabetes. Independent sample t-test, Mann-Whitney test and χ(2) -test were used to test for univariable associations and multiple logistic regression was used to adjust for confounders. RESULTS Four hundred and seventy eligible women were identified; the majority had a diagnosis of Type 2 diabetes (67%). Thirty-six per cent and 64% of women with Type 1 and Type 2 diabetes, respectively, were prescribed drugs not recommended for use in pregnancy (P < 0.001). Less than half were using concomitant contraception (P < 0.001). No significant difference of contraception use was observed between women who were and were not taking drugs not recommended for use in pregnancy (40 vs. 41%, P = 0.4). CONCLUSIONS Use of drugs not recommended during pregnancy in women with diabetes of child-bearing age is common but is not associated with increased use of contraception. There is need to identify and overcome barriers to effective contraception use for this population group in order to facilitate optimal management of cardiovascular risk.

Abstract
AIMS Women who develop diabetes during pregnancy are at significant risk of developing Type 2 diabetes later in life, and "should be offered blood glucose testing ... to exclude persisting hyperglycaemia" after delivery. New UK guidelines now recommend that this is done by measurement of fasting blood glucose, rather than an oral glucose tolerance test (OGTT). Our study aims to establish whether assessment by fasting blood glucose gives equivalent results to an OGTT. METHODS Retrospective data were obtained from four centres in the West Midlands, UK, who performed a postnatal OGTT on 470 women during a 12-month period. All centres used a 75 g, 2-h protocol. RESULTS 28 of 470 (6.0%) women had diabetes mellitus after testing of fasting plasma glucose. After OGTT, 70 women (14.9%) were found to have impaired glucose tolerance (IGT), and 10 further cases of diabetes were detected (overall prevalence of DM 8.1%). Of the 400 women with normal fasting plasma glucose. After OGTT, 70 women (14.9%) were found to have impaired glucose tolerance (IGT), and 10 further cases of diabetes were detected (overall prevalence of DM 8.1%). Of the 400 women with normal fasting plasma glucose (< or = 6.0 mmol/l), 55 were found to have impaired glucose tolerance and 4 had overt diabetes. In all, 26% of women with diabetes were missed by FPG. CONCLUSION Fasting plasma glucose alone does not allow detection of IGT, and misses a substantial proportion of women with Type 2 diabetes. Recognition of ongoing IGT or DM is important in identifying women who may benefit from lifestyle modification, and who may need early intervention in subsequent pregnancies. Our results suggest that OGTT should be the investigation of choice in the postnatal assessment of women who have had GDM.

Abstract
Hyperkalemia, especially if severe, is a frequent cause of cardiac rhythm pathologies. Sinus arrest of sudden onset is more likely to occur when the potassium level is very high (e.g. > 8 mmol/l) but in concomitance with negative chronotropic drugs it may occur even in presence of a moderate hyperkalemia. This case report highlights the fact that these kinds of drugs, especially in combination, are probably to be avoided in patients at risk of developing hyperkalemia (e.g. diabetics, renal failure, etc.), even of moderate degree, considering this life-threatening cardiac complication.

Abstract
Mer (MerTK) is a receptor tyrosine kinase important in platelet aggregation, as well as macrophage cytokine secretion and clearance of apoptotic cells. Mer is not normally expressed in thymocytes or lymphocytes; however, ectopic Mer RNA transcript and protein expression is found in a subset of acute lymphoblastic leukemia cell lines and patient samples, suggesting a role in leukemogenesis. To investigate the oncogenic potential of Mer in vivo, we created a transgenic mouse line (Mer(Tg)) that expresses Mer in the hematopoietic lineage under control of the Vav promoter. Ectopic expression and activation of the transgenic Mer protein was demonstrated in lymphocytes and thymocytes of the Mer(Tg) mice. At 12-24 months of age, greater than 55% of the Mer(Tg) mice, compared to 12% of the wild type, developed adenopathy, hepatosplenomegaly, and circulating lymphoblasts. Histopathological analysis and flow cytometry were consistent with T-cell lymphoblastic leukemia/lymphoma. Mer may contribute to leukemogenesis by activation of Akt and ERK1/2 anti-apoptotic signals, which were upregulated in Mer(Tg) mice. Additionally, a significant survival advantage was noted in Mer(Tg) lymphocytes compared to wild-type lymphocytes after dexamethasone treatment. These data suggest that Mer plays a cooperative role in leukemogenesis and may be an effective target for biologically based leukemia/lymphoma therapy.

Abstract
This study was conducted to compare the treatment efficacy between a prandial glucose regulator, repaglinide and a new sulphonylurea, glimepiride in Muslim Type 2 diabetic patients who practice Ramadan fasting. Forty-one patients, previously treated with a sulphonylurea or metformin, were divided to receive either repaglinide (n=20, preprandially three-times daily) or glimepiride (n=21, preprandially once daily) 3 months before the month of Ramadan. During Ramadan, patients modified their eating pattern to two meals daily, and the triple doses of repaglinide were redistributed to two preprandial doses. Four point blood glucose monitoring were performed weekly during the month of Ramadan and the subsequent month. Measurements of the 4-point blood glucose were significantly lower in the glimepiride group compared to the repaglinide group both during and after Ramadan. The glycaemic excursion was better in the morning for the repaglinide group and better in the afternoon and evening for the glimepiride group during the Ramadan period. There was no statistically significant difference in the incidence of hypoglycaemia between the two groups during and after Ramadan. There was no difference in the glycaemic excursion post-Ramadan. The longer duration of action of glimepiride may offer an advantage over repaglinide during the 13.5 hours of fast in Ramadan for diabetic patients.

Abstract
AIMS The aims of this study were first, to investigate the relationship between simple anthropometric measures of obesity with visceral fat as assessed by a single slice magnetic resonance imaging (MRI)-scan in patients attending a hospital clinic. Second, to determine which anthropometric measure best relates to the adverse metabolic profile of the metabolic syndrome. METHODS Forty-one male subjects [body mass index (BMI): 30.2 + 5.8 kg/m(2), age: 50.3 + 13.6 years] were studied by MRI-scan to measure visceral fat at L4/L5 level and to investigate its relationship with simple anthropometric measures. Second, we studied 83 male subjects to determine which anthropometric measure best predicts the metabolic complications (using the ATPIII criteria) of obesity in the setting of a hospital clinic. RESULTS Waist circumference was the best anthropometric measurement that correlated with MRI-visceral fat mass assessed at L4/L5 in 41 subjects who had an MRI scan (P = 0.0001, r(2) = 0.36, beta = 0.56) amongst variables which also included age, BMI, sagittal diameter, diabetes and ethnicity. Stepwise multiple regression analysis showed sagittal diameter (P = 0.001, r(2) = 0.4, beta = 0.406), age (P = 0.003, beta = 0.271) and waist circumference (P = 0.012, beta = 0.297) were the best predictors of the adverse metabolic profile of the metabolic syndrome in all 83 male subjects amongst BMI, waist-hip ratio (WHR), ethnicity and diabetes-related factors. CONCLUSIONS Waist circumference is a simple anthropometric parameter that best correlates with single slice MRI-scan, but sagittal diameter (measured using abdominal calipers) better predicts the adverse metabolic profile of the metabolic syndrome. Although there is considerable variation in abdominal fat topography between ethnic groups, and also within populations, sagittal diameter assessment is a technique that is simple and best predicts the metabolic syndrome.

Abstract
Glucocorticoids play an important role in the pathogenesis of obesity and insulin resistance. Impaired conversion of cortisone (E) to cortisol (F) by the type 1 isoenzyme of 11beta-hydroxysteroid dehydrogenase (11beta-HSD) in obesity may represent a protective mechanism preventing ongoing weight gain and glucose intolerance. We have studied glucocorticoid metabolism in 33 male subjects with type 2 diabetes mellitus [age, 44.2 +/- 13 yr; body mass index (BMI), 31.1 +/- 7.5 kg/m(2) (mean +/- sd)] and 38 normal controls (age, 41.4 +/- 14 yr; BMI, 38.2 +/- 12.8 kg/m(2)). Circulating F:E ratios were elevated in the diabetic group and correlated with serum cholesterol and homeostasis model assessment-S. There was no difference in 11beta-HSD1 activity between diabetic subjects and controls. In addition, 11beta-HSD1 activity was unaffected by BMI in diabetic subjects. However, in control subjects, increasing BMI was associated with a reduction in the urinary tetrahydrocortisol+5alpha-tetrahydrocortisol:tetrahydrocortisone ratio (P < 0.05) indicative of impaired 11beta-HSD1 activity. The degree of inhibition correlated tightly with visceral fat mass. Changes in 11beta-HSD1 activity could not be explained by circulating levels of adipocytokines. Impaired E to F metabolism in obesity may help preserve insulin sensitivity and prevent diabetes mellitus. Failure to down-regulate 11beta-HSD1 activity in patients with diabetes may potentiate dyslipidemia, insulin resistance, and obesity. Inhibition of 11beta-HSD1 may therefore represent a therapeutic strategy in patients with type 2 diabetes mellitus and obesity.

Abstract
In 2002, Clavibacter michiganensis subsp. michiganensis (Smith) Davis, the causal organism of bacterial canker of tomato (Lycopersicon esculentum), was isolated from two of six commercial asymptomatic tomato seed lots produced on Java in Indonesia. C. michiganensis subsp. michiganensis has not been reported in Indonesia previously. Methods based on the protocol of the International Seed Health Initiative were used to extract and identify the presence of C. michiganensis subsp. michiganensis in tomato seed. C. michiganensis subsp. michiganensis was isolated with dilution plating on the semiselective media D2ANX and mSCM. The identity of the colonies was confirmed by immunofluorescence microscopy, polymerase chain reaction (2), fatty methyl ester analysis, enzyme-linked immunosorbent assay based on monoclonal antibody 103 (1), and a pathogenicity test in which three replicate tomato plants were stem inoculated with 108 cells ml-1. Within 2 weeks, stripes on stems developed that split and exposed reddish brown cavities (stem cankers). The presence of C. michiganensis subsp. michiganensis poses a direct threat on tomato production, which is one of five economically most important vegetable crops in Indonesia. References: (1) A.

Abstract
BACKGROUND Inflammatory mediators such as tumor necrosis factor-alpha (TNF-alpha), interleukin 1beta (IL-1beta), IL-6, and interferon gamma (IFN-gamma) may change coronary plaque integrity by altering vascular smooth muscle cell (VSMC) survival and modifying the extracellular matrix. Insulin-like growth factor-1 (IGF-1) prevents apoptosis, promotes matrix formation, and can decrease TNF-alpha or IL-1beta--induced proteoglycan degradation. METHODS AND RESULTS To determine the effects of cytokines on the IGF-1 system, rat aortic VSMCs were exposed to TNF-alpha (10 to 500 ng/mL), IL-1beta (20 pg to 10 ng/mL), IL-6 (100 pg to 15 ng/mL), or IFN-gamma (10 to 600 U/mL). IL-1beta, IL-6, and IFN-gamma did not regulate IGF-1, IGF-1 receptor (R), or IGF binding proteins (IGFBPs). However, TNF-alpha markedly decreased IGF-1 mRNA (85% reduction at 24 hours) and increased IGFBP-3 mRNA and protein (300% increase at 24 hours). These changes were blocked by actinomycin D, consistent with a transcriptional mechanism. Experiments using TNF binding protein-1 indicated that these effects were not attributable to secretion of an autocrine factor. Anti--IGFBP-3 antibodies increased VSMC DNA synthesis 3-fold. In addition, apoptosis induced by TNF-alpha, IFN-gamma, and Fas ligand was markedly reduced by desamino-(1-3)-IGF-1. CONCLUSIONS TNF-alpha, a cytokine that is upregulated in atherosclerotic plaques, reduces IGF-1 and increases IGFBP-3 in VSMCs, likely leading to a reduction in bioactive IGF-1. Because IGF-1 is important for growth and survival of VSMCs, its downregulation by TNF-alpha possibly plays a crucial role in acute and chronic coronary syndromes by decreasing VSMC viability and promoting plaque instability.

Abstract
Insulin-like growth factor-1 (IGF-1) plays an important role in migration, cell cycle progression and survival of vascular smooth muscle cells (VSMC). We investigated the specific localization of IGF-1 and its receptor (IGF-1R) and their association with apoptosis and the expression of apoptosis-related proteins in early and advanced atherosclerotic lesions. Human atherosclerotic plaques (n=23) from patients undergoing aortic, carotid or femoral arterial surgery were studied. Immunohistochemistry and in situ hybridization revealed significantly higher expression of IGF-1 and IGF-1R in the media than in the intima of early atherosclerotic lesions (P<0.01). Medial VSMC positive for BAX, a proapoptotic protein of the B-cell CLL/lymphoma 2 (BCL2) family, showed colocalization of IGF-1. Apoptosis, as detected by DNA in situ terminal deoxynucleotidyl transferase end labeling (TUNEL), was not present in these early lesions. In advanced atherosclerotic plaques, the expression of IGF-1 and IGF-1R was significantly lower in the intimal regions with macrophage infiltration than in those without macrophage infiltration or than in the media (P<0.01). Furthermore, IGF-1 and IGF-1R immunoreactivity was markedly lower in intimal TUNEL-positive VSMC compared with intimal BAX-positive and medial VSMC (P<0.01). We conclude that IGF-1 and IGF-1R expression are reduced in the deep intima of early atherosclerotic lesions and in areas of advanced plaques with macrophage infiltration. Since IGF-1 is a potent survival factor for VSMC, poor expression of IGF-1 and IGF-1R in intimal regions with macrophage infiltration would likely contribute to triggering VSMC apoptosis potentially leading to plaque weakening, plaque rupture and acute coronary events.

Abstract
AIM To examine the expression of oestrogen receptors alpha and beta (ERalpha and ERbeta) and their regulation by 17beta-oestradiol (E2) in stromal cells and adipocytes from human subcutaneous (s.c.) and omental (o.m.) adipose tissue. METHODS Subcutaneous and o.m. abdominal adipose tissues were obtained from 10 women (mean age 63.5 +/- 4.8 years; mean weight 75.6 +/- 6.7 kg) undergoing elective or cosmetic surgery. Immunohistochemistry and RT-PCR analysis were used to detect the presence of ERalpha and ERbeta. The regulation of ERalpha and ERbeta by E(2) (10(-7) M to 10(-9) M) was examined using Western immunoblotting analysis in both s.c. and o.m. stromal cells and mature adipocytes cultured in serum-free, phenol red-free medium. RESULTS Immunostaining of s.c. and o.m. adipose tissue showed that the ER subtypes were localized predominantly within the nucleus. Western analysis demonstrated that E2 treatments differentially altered ERalpha and ERbeta expression in s.c. and o.m. adipocytes. In s.c. and o.m. stromal cells, E(2) (10(-8) M) produced a significant up regulation relative to control of 66 kDa ERalpha (s.c.:1.87 +/- 0.22; o.m.:1.97 +/- 0.17; p < 0.05) and 60 kDa ERbeta (s.c.:1.66 +/- 0.3; o.m.: 1.68 +/- 0.16; p < 0.05). In s.c. adipocytes, however, ERalpha expression significantly decreased with E(2) 10(-8) M relative to control while ERbeta expression increased (ERalpha 0.58 +/- 0.06, ERbeta: 1.47 +/- 0.11; p < 0.05). In o.m. adipocytes, the inhibition of ERalpha with E(2) was not observed (ERalpha 1.86 +/- 0.36, ERbeta:1.03 +/- 0.15, p < 0.05) CONCLUSIONS ERalpha and ERbeta are expressed but differentially regulated by E(2) in s.c. and o.m. adipocytes and stromal cells. The upregulation of ERbeta by E(2) suggests that E(2) maintains the expression of these receptors. The feed-back inhibition of ERalpha expression by E(2) in s.c. but not o.m. adipocytes observed in vitro is consistent with the data from ERalpha knock out mice where s.c. fat is increased. Selective ER modulators may have different effects in different adipose sites.

Abstract
Use of lectins as ligands for the immobilization and stabilization of glycoenzymes has immense application in enzyme research and industry. But their widespread use could be limited by the high cost of their production. In the present study preparation of a novel and inexpensive lectin support for use in the immobilization of glycoenzymes containing mannose or glucose residues in their carbohydrate moiety has been described. Cajanus cajan lectin (CCL) coupled covalently to cyanogen bromide activated Seralose 4B could readily bind enzymes such as invertase, glucoamylase and glucose oxidase. The immobilized and glutaraldehyde crosslinked preparations of invertase exhibited high resistance to inactivation upon exposure to enhanced temperature, pH, denaturants and proteolysis. Binding of invertase to CCL-Seralose was however found to be readily reversible in the presence of 1.0 M methyl alpha-D mannopyranoside. In a laboratory scale column reactor the CCL-Seralose bound invertase was stable for a month and retained more than 80% of its initial activity even after 60 days of storage at 4 degrees C. CCL-Seralose bound invertase exhibited marked stability towards temperature, pH changes and denaturants suggesting its potential to be used as an excellent support for the immobilization of other glycoenzymes as well.
