Abstract
Present study aimed to assess effect of pre-treatment with Mucuna pruriens seed extract and its bioactive molecule(s) on NMDAR and Tau protein gene expression in cerebral ischemic rodent model. Methanol extract of M. pruriens seeds was characterized by HPLC, and β-sitosterol was isolated by flash chromatography. In vivo studies to observe the effect of pre-treatment (28 days) with methanol extract of M. pruriens seed and β-sitosterol on the unilateral cerebral ischemic rat model. Cerebral ischemia induced by left common carotid artery occlusion (LCCAO) for 75 min (on day 29) followed by reperfusion for 12 h. Rats (n = 48) divided into four groups. GroupI (control,Untreated + LCCAO)-No pre-treatment + cerebral ischemia; GroupII(β-sitosterol + Sham)-pre-treatment with β-sitosterol, 10 mg/kg/day + sham-operated; GroupIII(β-sitosterol + LCCAO)-pre-treatment with β-sitosterol, 10 mg/kg/day + cerebral ischemia; GroupIV(methanol extract + LCCAO)-pre-treatment with methanol extract of M. pruriens seeds, 50 mg/kg/day + cerebral ischemia. Neurological deficit score was assessed just before sacrifice. Experimental animals were sacrificed after 12 h reperfusion. Brain histopathology was performed. Gene expression of NMDAR and Tau protein of left cerebral hemisphere (occluded side) was performed by RT-PCR. Results revealed that the neurological deficit score was lower in groups III and IV compared to group I. NMDAR and tau protein mRNA expression in left cerebral hemisphere were upregulated in Group I, downregulated in groups III and IV. Histopathology of left cerebral hemisphere (occluded side) in Group I showed features of ischemic brain damage. Groups III and IV, left cerebral hemisphere showed less ischemic damage compared GroupI. Right cerebral hemisphere showed no areas of ischemia-induced brain changes. Pre-treatment with β-sitosterol and methanol extract of M. pruriens seeds may reduce ischemic brain injury following unilateral common carotid artery occlusion in rats.

Abstract
Soil salinity affects various crop cultivation but legumes are the most sensitive to salinity. Osmotic stress is the first stage of salinity stress caused by excess salts in the soil on plants which adversely affects the growth instantly. The Trehalose-6-phosphate synthase (TPS) genes play a key role in the regulation of abiotic stresses resistance from the high expression of different isoform. Selected genotypes were evaluated to estimate for salt tolerance as well as genetic variability at morphological and molecular level. Allelic variations were identified in some of the selected genotypes for the TPS gene. A comprehensive analysis of the TPS gene from selected genotypes was conducted. Presence of significant genetic variability among the genotypes was found for salinity tolerance. This is the first report of allelic variation of TPS gene from chickpea and results indicates that the SNPs present in these conserved regions may contribute largely to functional distinction. The nucleotide sequence analysis suggests that the TPS gene sequences were found to be conserved among the genotypes. Some selected genotypes were evaluated to estimate for salt tolerance as well as for comparative analysis of physiological, molecular and allelic variability for salt responsive gene Trehalose-6-Phosphate Synthase through sequence similarity. Allelic variations were identified in some selected genotypes for the TPS gene. It is found that Pusa362, Pusa1103, and IG5856 are the most salt-tolerant lines and the results indicates that the identified genotypes can be used as a reliable donor for the chickpea improvement programs for salinity tolerance.

Abstract
OBJECTIVES Dietary high fat possibly causes oxidative stress; also it makes deleterious effect on kidney functions and land up in lipotoxicity in renal tissue. Lipotoxicity is the pathological situation where lipid Peroxidation occurs and generates reactive oxygen species (ROS). Overproduction of ROS than antioxidant present in tissues cause oxidative stress. Terminalia arjuna is found to be potential antioxidant that counteract oxidative stress and possibly maintain glomerular integrity. METHODS Ethanolic extract of T. arjuna (ETO) was prepared and phytochemical analysis was done. Rats were divided into four groups, having six rats in each group as following; group 1-Control (20% fat); group 2 (ETO 100 mg/kg/b.wt); group 3 (30% fat) and group 4 (30% fat + ETO 100 mg/kg/b.wt). Dietary and ETO supplementation were continued for 21 days. Gravimetric, kidney functions (blood urea and serum creatinine) and oxidative stress markers like MDA, SOD and GSH were evaluated. Histopathological analysis was done on kidney along with measurement of glomerular integrity. Morphometrical analysis of glomerular integrity was evaluated by measuring glomerular length, width, glomerular area and Bowman's capsule radius. One way ANOVA was done for analysis of data. RESULTS Blood urea and serum creatinine levels were significantly higher in high fat fed rats indicating renal dysfunction. High fat diet showed significant increase in MDA, decrease in SOD and GSH in rats fed with high fat diet, which indicate generation of oxidative stress. Supplementation of ETO showed amelioratic effect against high fat diet induced renal dysfunction and oxidative stress. Histopathological findings were significantly corroborated with morphometrical analysis of glomerular integrity. CONCLUSIONS Ethanolic extracts of T. arjuna supplementation found to be beneficial against high fat induced renal alterations in terms of functions and architecture.

Abstract
OBJECTIVE Patients exposed to chronic sustained hypoxia frequently develop cardiovascular disease risk factors to ultimately succumb to adverse cardiovascular events. In this context, the present study intends to assess the role of cilnidipine (Cil), a unique calcium channel blocker that blocks both L-type and N-type calcium channels, on cardiovascular pathophysiology in face of chronic sustained hypoxia exposure. MATERIALS AND METHODS The study involved Wistar strain albino rats. The group-wise allocation of the experimental animals is as follows - Group 1, control (21% O2); Group 2, chronic hypoxia (CH) (10% O2, 90% N); Group 3, Cil + 21% O2; and Group 4, CH (10% O2, 90% N) + Cil (CH + Cil). Cardiovascular hemodynamics, heart rate variability, and endothelial functions (serum nitric oxide [NO], serum endothelial nitric oxide synthase [NOS3], and serum vascular endothelial growth factor [VEGF]) were assessed. Cardiovascular remodeling was studied by histopathological examination of the ventricular tissues, coronary artery (intramyocardial), and elastic and muscular arteries. Normalized wall index of the coronary artery was also calculated. RESULTS AND CONCLUSION The results demonstrated altered cardiovascular hemodynamics, disturbed cardiovascular autonomic balance, increased levels of VEGF and NOS3, and decreased bioavailability of NO on exposure to chronic sustained hypoxia. The histopathological examination further pointed toward cardiovascular remodeling. Treatment with Cil ameliorated the cardiovascular remodeling and endothelial dysfunction induced by CH exposure, which may be due to its blocking actions on L/N-type of calcium channels, indicating the possible therapeutic role of Cil against CH-induced cardiovascular pathophysiology.

Abstract
BACKGROUND Dietary high fat possibly causes oxidative stress. Also, it alters the pathophysiology of metabolically active myocardial tissues and vascular architecture. Emblica officinalis contains a potential antioxidant that counteracts oxidative stress and possibly maintains vascular integrity. OBJECTIVES To assess the effect of ethanolic extract of Emblica officinalis (EEO) on High Fat Diet (HFD) induced changes in vascular chemistry and histopathology of the cardiovascular system in male albino rats. MATERIALS AND METHODS Ethanolic extract of Emblica officinalis (EEO) was prepared and phytochemical analysis was done. Rats were divided into four groups, having six rats in each group as follows: group 1- Control (20% fat); group 2 (20% fat+ EEO 100 mg/kg/b w); group 3 (30% fat) and group 4 (30% fat + EEO 100 mg/kg/b w). Dietary and EEO supplementation was continued for 21 days. Gravimetric and oxidative stress markers like MDA, NO, antioxidants like Vitamin C and E, and molecular marker (NOS3) were evaluated. Histopathological analysis was done on the myocardium and elastic artery along with measurement of coronary arterial wall thickness and lumen diameter. One way ANOVA was done for analysis of data. RESULTS High fat diet showed a significant increase in MDA, decrease of NO with unaltered NOS3 protein in rats fed with high fat diet, which indicate possible alteration of vascular pathophysiology. Supplementation of EEO showed an ameliorating effect on high fat diet induced oxidative stress. These results were further corroborated with findings of a histopathological study on the myocardium, elastic artery and coronary arterial architecture. CONCLUSION Ethanolic extract of Emblica officinalis (EEO) indicates its cardioprotective efficacy against rats fed with high fat diet.

Abstract
Carbonaceous meteorites provide clues with regard to prebiotic chemistry and the origin of life. Geological Survey of India recorded a carbonaceous chondrite meteorite fall in Mukundpura, India, on June 6, 2017. We conducted a study to investigate the microbial community that survived the meteorite impact. 16S rRNA metagenomic sequencing indicates the presence of Actinobacteria, Proteobacteria, and Acidobacteria in meteorite impact soil. Comparative phylogenetic analysis revealed an intriguing abundance of class Bacilli in the impact soil. Bacillus thermocopriae IR-1, a moderately thermotolerant organism, was isolated from a rock, impacted by the Mukundpura meteorite. We investigated the resilience of B. thermocopriae IR-1 to environmental stresses and impact shock in a Reddy shock tube. Bacillus thermocopriae IR-1 survived (28.82% survival) the effect of shock waves at a peak shock pressure of 300 kPa, temperature 400 K, and Mach number of 1.47. This investigation presents the first report on the effect of impact shock on B. thermocopriae IR-1. The study is also the first report on studying the microbial diversity and isolation of bacteria from impact crater soil immediately after meteorite impact event.

Abstract
OBJECTIVE: This study was aimed to assess the effect of unilateral common carotid artery occlusion on brain pathophysiology in rats pretreated with subchronic hypoxia. MATERIALS AND METHODS: Rats (200 ± 20 g) were randomized into three groups: Group 1 served as sham, Group 2 were normoxic (21% O2 and 79% N2), and Group 3 were hypoxia preconditioned (10% O2 and 90% N2) for 21 days before left common carotid artery occlusion (LCCAO). The LCCAO was done for 75 min followed by reperfusion for 12 h. Neurological scores were recorded. Serum malondialdehyde (MDA) and nitric oxide (NO) levels at pre- and 12 h post-LCCAO were measured. Brain histopathological assessments were also done. RESULTS: Higher neurological deficits scores in Group 2 as compared to Group 3 rats were noticed. Serum MDA and NO levels at 12 h post-LCCAO in Group 2 rats showed significant elevation as compared to preocclusion levels. Group 3 rats did not show such elevations. On histopathology of left and right cerebral hemispheres of Group 1 (sham) did not show any specific changes. In Group 2 rats, the right cerebral hemisphere (nonoccluded) showed no areas of ischemia-induced brain changes, but in the left side (occlusive), there were features of ischemic brain damage including cerebral edema. In the case of Group 3 rats, there were less ischemic damages in the left occluded side as compared to the left side of the Group 2 rats. CONCLUSION: This study clearly demonstrates that subchronic hypoxia pretreatment can reduce ischemic brain injury by unilateral common carotid artery occlusion in rats.

Abstract
BACKGROUND Kenaf (Hibiscus cannabinus Linn, Pundi), Chick pea (Cicer arietinum Linn, Chana) and Prickly lettuce (Lactuca scariola Linn, Hattaraki) leaves are a few of indigenous plants which are routinely consumed by the people of north Karnataka in the diet. Studies on these plants showed some potential anti-diabetic efficacies. OBJECTIVES To examine the effect of leaves extracts of Hibiscus cannabinus Linn, Cicer arietinum Linn and Lactuca scariola Linn on cardiovascular integrity, glucose homeostasis and oxygen sensing cell signaling mechanisms in alloxan induced diabetic rats. METHOD In vitro and in vivo tests on glucose regulatory systems and molecular markers such as - NOS3, HIF- 1α and VEGF were conducted in alloxan induced diabetic rats supplemented with all the three plant extracts. Electrophysiological analysis (HRV, LF: HF ratio, baroreflex sensitivity, BRS) and histopathogy of myocardial tissues and elastic artery were evaluated in diabetic rats treated with L. scariola linn. RESULTS Out of these three plant extracts, Lactuca scariola Linn supplementation showed significant beneficial effects on glucose homeostasis and oxygen sensing cell signaling pathways in alloxaninduced diabetic rats. Furthermore, effects of sub chronic supplementation of Lactuca scariola Linn aqueous extracts showed significant improvement in sympatho-vagal balance in diabetic rats by increase of Heart Rate Variability (HRV) and regaining of Baroreflex Sensitivity (BRS). These results were also corroborated with myocardial and elastic artery histopathology of Lactuca scariola Linn supplemented diabetic rats. CONCLUSION These findings indicate an adaptive pathway for glucose homeostasis, oxygen sensing cell signaling mechanisms and cardio protective actions in alloxan - induced diabetic rats supplemented with Lactuca scariola Linn extracts.

Abstract
Introduction Dietary high fat alters lipid profile and possibly induce sympatho-vagal imbalance. Emblica officinalis is found to be potential antioxidant and possibly counteract hyperlipidemia induced lipid peroxidation. Aim To assess Ethanolic extract of Emblica Officinalis (EEO) as lipid lowering and cardiovascular protective agent against high dietary fat supplemented to experimental rats. Further to study a comparative analysis between EEO and atorvastatin on hyperlipidemia and cardiovascular integrity. Materials and Methods EEO was prepared and phytochemical analysis was done. Rats were divided into five groups, having six rats in each group as following; Group I-control (20% fat); Group II (+ EEO 100 mg/kg body wt); Group III (fed with high fat diet; 30% fat); Group IV (fed with high fat diet; 30% fat + EEO 100 mg/kg body wt) and Group V (fed with high fat diet; 30% fat + atorvastatin 4 mg/kg body wt). The treatments were continued for 21 days. Gravimetric parameters and electrophysiological parameters {Heart Rate (HR), sympatho-vagal balance} were recorded and lipid profiles of all the groups were measured. ANOVA, correlation and multiple regressions were done for analysis of data. Results Significant alteration in serum lipid profile was observed in rats fed with high dietary fat but supplementation of EEO was found to be reversible. Electrophysiological evaluation revealed altered HR and sympatho-vagal balance in high dietary fat fed rats (Group III) which indicate cardiac autonomic malfunctions which were found to be improved in Emblica officinalis supplemented group of rats (Group IV). Further, analysis has shown significant negative correlation between HDL/LDL and sympatho-vagal balance in all groups of rats which clearly indicate a role of dietary fat on sympatho-vagal balance. These results further corroborated with findings of histopathological study on myocardium and elastic artery. Conclusion Observations from the study indicate a beneficial role of ethanolic extract of Emblica officinalis (amla) on dyslipidemia and cardiac autonomic functions in rats treated with high fat diet.

Abstract
Purpose: The purpose of the study was to evaluate the presentation and management of posthysterectomy ureteral injuries. Patients and Methods: Fourteen patients with ureteric injuries after hysterectomy for benign diseases were evaluated. The diagnosis was done based on clinical presentation, intravenous urogram, computed tomography, cystoscopy, and retrograde pyelogram (RGP) depending on the clinical situation. Results: Sixteen iatrogenic ureteric injuries in 14 patients over a 2-year period were evaluated. Hysterectomy was the cause of injury in all the cases, 12 abdominal and 2 were vaginal. Two patients presented with anuria, one had ureteric, and bladder injury with hemoperitoneum underwent emergency laparotomy and bilateral ureteral reimplantation. Another patient underwent RGP followed by stenting on the right side, left side unable to put stent so percutaneous nephrostomy (PCN) was done followed by antegrade stenting later. Two patients presented with septicemia and pyonephrosis were managed initially with PCN followed by balloon dilatation and JJ stenting. RGP and retrograde stenting was done in seven of the remaining ten patients and ureteric reimplantation in three patients. Conclusion: Patient with ureteric injury should be evaluated and intervened at the earliest. Patients presenting early, within 2 weeks after hysterectomy have higher chances of success with endourological procedures, obviating the need for open surgery.

Abstract
A cross sectional study of 136 women age group40-55 years was conducted to study which anthropometric measure had the strongest association with cardiovascular disease risk factors in middle aged women. In accordance with their BMI measurement subjects were divided into three groups namely: Normal weight (Group1) BMI 18.5-24.9 kg/m2, Overweight (Group2) - 25 kg/m2 - 29.9 kg/m2, Obese (Group3) - BMI > 30 kg/m2. Each group was further divided into premenopausal and postmenopausal women BMI, WHR, WHtR, SBP, DBP were recorded. TG, TC, HDL and FBS values were estimated. Results showed that both pre and post menopausal middle aged obese women with higher BMI, WHR and WHtR have more chances of having cardiovascular diseases. BMI, WHR and WHtR are theeasy and practical methods to diagnose obesity and together can be used as simple measures to predict cardiovascular risk factors in middle aged women.

Abstract
Variations of venous pattern in the arm are common. In this case report, we present a variation of axillary artery and vein. During routine educational dissections of axillary region, it was observed that a fenestrated axillary vein was perforated by a variant axillary artery in right arm of an old male cadaver. The axillary artery which was fenestrated through axillary vein had only two branches arising from its second part and no branches from its remaining distal parts. The branches are thoraco-acromial (usual) and another large collateral (unusual) branch. This collateral branch is the origin of several important arteries as the subscapular, circumflex scapular, posterior circumflex humeral and lateral thoracic arteries. We propose to name this artery as collateral axillary arterial trunk. The course of this collateral axillary arterial trunk and its branches and also clinical significance of this variation are discussed in the paper.

Abstract
Hypertension is one of the common diseases affecting general population. The World Health Organization has concluded that hypertension is the major factor responsible for the most deaths worldwide, 12.8% per year or more than seven million. Additionally hypertension is rated third on the list of factors responsible for the burden of disease during life, as measured by disability-adjusted life-years. The study, diagnosis and treatment of hypertension in the young constitute one of the major health challenges today, because of high percentage of potentially curable chance if the cause could be found. Indeed intensive study and investigations are required to unravel the underlying cause. Here we present a case of typical Takayasu arteritis presented with swelling in the right neck and hypertension.

However, the manifestation and progression of the disease is influenced by a wide variety of determinants and factors. The strongest type of causal relationship is the association of systemic and periodontal disease. Hashimotos thyroiditis has also been considered as one of the causes of periodontal disease. As a matter of fact, on an autoimmune basis, in Hashimotos disease and periodontal disease, we have made an attempt to derive the common mechanisms, with an evidence base. The need for this kind of review was due to the fact that the outcome of periodontal therapy did not give the expected results in patients with Hashimoto's thyroiditis. Hence, a possible link between Hashimotos thyroiditis and periodontitis was considered.

Abstract
The public awareness about cell phone safety increased greatly in the last few years as various reports of potential adverse health effects on humans exposed to radiations emitted from cellular phones were published. The aim of the study was to assess the effect of long term cell phone exposure on physiological and hematological parameters along with its impact on serum lipid profiles and a single call effect on heart rate, blood pressure and SpO2(%) of healthy male medical students. The students were divided into two groups, group I (n=22, age 20.63 +/- 1.17 yrs) comprising first year medical students who were never exposed to cell phones at the time of this study and group II (n=35, age 22.00 +/- 1.56 yrs) consists of final year (fourth year) male medical students who were using cell phone for more than four years before this study. The results showed no significant differences the groups in basal heart rate, systolic blood pressure, SpO2(%), or various hematologic parameters. Acute exposure (single call of cell phone with 900 MHz for 1 minute) in both groups showed a significant increase in peak heart rate in group II as compared with group I and a significant decrease in peak SpO2 (%) in group I as compared with group II. Serum total cholesterol, VLDL-cholesterol, and triglycerides concentration were significantly higher in group II (long term cell phone exposed) than in group I, suggesting a mild alteration of lipid profile among group II subjects.

Abstract
AIM This study investigated the quorum sensing, biofilm and type three secretion system (TTSS) inhibitory properties of citrus flavonoids. METHODS AND RESULTS Flavonoids were tested for their ability to inhibit quorum sensing using Vibrio harveyi reporter assay. Biofilm assays were carried out in 96-well plates. Inhibition of biofilm formation in Escherichia coli O157:H7 and V. harveyi by citrus flavonoids was measured. Furthermore, effect of naringenin on expression of V. harveyi TTSS was investigated by semi-quantitative PCR. Differential responses for different flavonoids were observed for different cell-cell signalling systems. Among the tested flavonoids, naringenin, kaempferol, quercetin and apigenin were effective antagonists of cell-cell signalling. Furthermore, these flavonoids suppressed the biofilm formation in V. harveyi and E. coli O157:H7. In addition, naringenin altered the expression of genes encoding TTSS in V. harveyi. CONCLUSION The results of the study indicate a potential modulation of bacterial cell-cell communication, E. coli O157:H7 biofilm and V. harveyi virulence, by flavonoids especially naringenin, quercetin, sinensetin and apigenin. Among the tested flavonoids, naringenin emerged as potent and possibly a nonspecific inhibitor of autoinducer-mediated cell-cell signalling. Naringenin and other flavonoids are prominent secondary metabolites present in citrus species. Therefore, citrus, being a major source of some of these flavonoids and by virtue of widely consumed fruit, may modulate the intestinal microflora. SIGNIFICANCE AND IMPACT OF THE STUDY Currently, a limited number of naturally occurring compounds have demonstrated their potential in inhibition of cell-cell communications; therefore, citrus flavonoids may be useful as lead compounds for the development of antipathogenic agents.

Abstract
Oropharyngeal candidiasis (OPC) continues to be a common opportunistic infection in patients infected with Human Immunodeficiency Virus (HIV) and is predictive of increasing immunosuppression. Though Candida albicans remains the predominant isolate, a rise in the frequency of isolation of non-albicans Candida (NAC) species is being observed. The levels of virulence and the sensitivities to available antifungal drugs vary among these species. Of 340 HIV seropositive patients in this study, 132 (38.8%) had oral lesions suggestive of candidiasis. Samples were collected from the lesion using sterile cotton swabs. Isolation and speciation were done by standard techniques. Antifungal drug susceptibility testing was done by macro broth dilution. The total number of Candida isolates was 135, of which, 45 (33.3%) were NAC species and 90 were C.albicans (66.6%). Of the NAC species, C. dubliniensis was the predominant pathogen (22,48.9%). Antifungal susceptibility testing showed that 14 (31.1%) of the NAC species and 11 (12.2%) of C. albicans were resistant to fluconazole (MIC > 8 microg/ml). A very high MIC of > 32 microg/ml was noted among the NAC species resistant to fluconazole.

Abstract
BACKGROUND We reported that drinking citrus juice improves bone quality in orchidectomized senescent male rats. Because cranberry juice, like citrus, is rich in nutrients and phenolic compounds, beneficial effects of citrus juice might also be seen with cranberry juice. An experiment evaluated effect of drinking cranberry juice on bone quality in orchidectomized rats. METHODS Thirty-two 1-year-old male rats were randomized to two groups: a sham-control group (n=8) and an orchidectomized group (n=24). The treatments for the 4 months duration of the study were SHAM, orchidectomy (ORX), ORX+drinking either 27% or 45% cranberry juice concentrate added to drinking water. At the termination of the study, the rats were euthanized, blood was collected for plasma antioxidant status and IGF-I. The femur, tibia and the 4th lumbar were evaluated for bone quality. Total calcium and magnesium concentration in the femurs were also evaluated. RESULTS ORX did not affect red blood cell (RBC)-induced hemolysis despite lowering (p<0.05) plasma antioxidant capacity; reduced (p<0.05) plasma IGF-I, femoral density, femoral strength, time-induced femoral fracture, bone mineral content, bone mineral area; numerically (p=0.07) lowered 4th lumbar density; decreased (p<0.05) trabecular connectivity, trabecular number, femoral ash; increased (p<0.05) trabecular separation in comparison to the SHAM group. Drinking cranberry juice increased (p<0.05) plasma antioxidant status, protected RBC against hemolysis, but had no positive effect on bone quality or bone mineral status. CONCLUSIONS Cranberry juice increases plasma antioxidant status without affecting bone quality.

Abstract
Gametophytic selection can drastically reduce the number of selection cycles during crop improvement programs. The objective of the present investigation was to test whether the nature of inheritance of two unlinked disease-resistant loci, h(1) and h(2), against Fusarium wilt in chickpea (Cicer arietinum L.) under gametophytic (pollen) selection was similar to that already observed at sporophytic level. A homozygous dominant (H(1)H(1)H(2)H(2)) susceptible genotype JG-62 was crossed to a recessive (h(1)h(1)h(2)h(2)) resistant genotype WR-315 to produce 20 F(1) hybrid seeds. In the following generation, flower buds of 10 F(1) hybrid plants were subjected to toxin stress before anthesis and the remaining ten control F(1) plants' flowers were sprayed with water. Thirty-four selected BC(1) plants were generated by test crossing resistant WR-315 individuals with pollen from toxin-stressed F(1) individuals. Both control and treated F(1) plants were selfed to produce respective F(2) generations. Two DNA markers, CS-27(700bp) and A07C(430bp), linked to susceptible alleles H(1) and H(2), respectively, were used to study the inheritance patterns of h(1) and h(2) loci in the F(2) and BC(1) generations. One hundred and forty-four selected F(2), 129 control F(2), and 34 selected backcross individuals were tested for the presence or absence of DNA markers. Except for the control F(2), observed ratios of selected F(2) and BC(1) populations exhibited significant chi-square deviations from expected monogenic and digenic ratios. Our results suggest that gametophytic selection is as effective as that realized at the sporophytic level, and that the gametophytic selection can be an effective breeding tool for plant breeding programs.

Abstract
Limonoids have been shown to inhibit the growth of estrogen receptor-negative and -positive human breast cancer cells in culture. The primary objective of this study was to test the antiproliferative activity of limonoids (obacunone 17 beta-D-glucopyranoside, nomilinic acid 17 beta-D-glucopyranoside, limonin, nomilin, and a limonoid glucoside mixture), found in high concentrations in mandarin (Citrus reticulata Blanco), against a series of human cancer cell lines. The human cancer cell lines included leukemia (HL-60), ovary (SKOV-3), cervix (HeLa), stomach (NCI-SNU-1), liver (Hep G2), and breast (MCF-7). The growth-inhibitory effects of the four limonoids and the limonoid glucoside mixture against MCF-7 cells were significant, and the antiproliferative activity of the different citrus limonoids was also dose and time dependent. No significant effects were observed on growth of the other cancer cell lines treated with the four individual limonoids at 100 micrograms/ml. At 100 micrograms/ml, the limonoid glucoside mixture demonstrated a partial inhibitory effect on SKOV-3 cancer cells. With use of flow cytometry, it was found that all the limonoid samples could induce apoptosis in MCF-7 cells at relatively high concentrations (100 micrograms/ml). Considering the high concentration needed to induce apoptosis, it is unlikely that this is the primary mechanism of action for the cytotoxic effects seen with limonoids in this study. Further work is needed in this area to establish the mechanism of action of citrus limonoids on human breast cancer cells.

Abstract
This study was undertaken to characterize the pectin from four citrus species and to determine their in vitro inhibitory activities on the binding of fibroblast growth factor (FGF) to the FGF receptor (FGFR). Pectin from various parts of lemon, grapefruit, tangerine, and orange were isolated and characterized. Tangerine had the highest pectin content among the four citrus species. Segment membrane contained as much as or more pectin than flavedo/albedo. Anhydrogalacturonic content was highest in pectin from segment membrane of tangerine and flavedo/albedo of grapefruit. Lemon pectin contained the highest methoxyl content (MC), and grapefruit contained the largest proportion of lower molecular weight (<10000 Da) pectin. Tangerine contained the highest neutral sugar in both flavedo/albedo and segment membrane. The interdependency of heparin on factor-receptor interaction provides a means for identifying new antagonists of growth factor activity and thus for treatment of various diseases. These results showed that pectin significantly inhibited the binding of FGF-1 to FGFR1 in the presence of 0.1 microg/mL heparin. The pectin from the segment membrane of lemon was the most potent inhibitor. The inhibition activity was significantly correlated with sugar content, MC, and size of pectin. Kinetic studies revealed a competitive nature of pectin inhibition with the heparin, a crucial component of the FGF signal transduction process. The observation that the heparin-dependent biological activity of FGF signal transduction is antagonized by citrus pectin should be further investigated for the use of these pectins as anti-growth factor agents for potential health benefits.
